Even if insect pest populations can be reduced by increasing plant diversity through intercropping, natural enemies are not always favored in such systems. Alternatively, semiochemical substances have been tested to enhance biological control, with inconsistent results. Combining both strategies can be an interesting way to maximize pest control. In this work, a 2-year setup involving wheat–pea strip intercropping combined with the release of E-b-farnesene (EBF) or methyl salicylate (MeSA) was tested as a push–pull strategy to simultaneously repel aphids and attract beneficials. Two types of slow-release formulation (i.e., oil and alginate beads) containing EBF or MeSA were deployed with the intercropping. The abundance of aphids was significantly decreased, while hoverfly larvae and mummified aphids increased on both pea plants and wheat tillers by the release of oil-formulated EBF and MeSA. The proportion parasitism of the aphid-parasitism rate [mummies/(aphids + mummies)] was also increased by treating both crops in both years. Releasing EBF through oil rather than alginate beads proved significantly better for attracting natural enemies and reducing aphids. Aphids were negatively correlated with the density of hoverflies (both adults and larvae) and numbers of mummies. All these results showed that combining intercropping with the release of EBF or MeSA formulated in oil can significantly reduce aphid density and attract their natural enemies. Therefore, the combination of both strategies could help farmers reduce the use of insecticides. [less ▲]

Au fil des siècles, le corpus latin des vitae sanctorum et des passiones martyrum s’est enrichi par l’introduction de nouveaux textes, par la réécriture et l’adaptation d’anciens remis au goût du jour, ainsi que par la traduction d’oeuvres issues du monde byzantin. Le phénomène de la réécriture hagiographique est bien connu et a fait l’objet de nombreux travaux. Celui de la traduction dans ce domaine reste en revanche peu exploité, tant il existe d’obstacles à son étude (absence de répertoire, manque d’éditions critiques, difficultés à identifier les traductions et les modèles grecs, etc.). Le présent travail propose une approche originale du phénomène, basée sur l’utilisation de la statistique linguistique. Cette approche consiste à étudier le latin utilisé par les traducteurs hagiographes pour rendre leur modèle grec et les techniques qu’ils ont adoptées pour le traduire en considérant les traductions non pas une à une, mais d’une manière comparative au moyen de l’analyse quantitative, dans le but de caractériser et de classer les traductions sur base de critères linguistiques, d’identifier et de qualifier des pratiques, des traditions localisées, des spécificités d’école ou de traducteur. La pratique de la traduction est examinée à travers un corpus de 35 textes représentatif des différentes phases de l’histoire de la traduction hagiographique latine au Moyen Âge et des différents foyers de traduction en Italie. Les analyses sont menées sur divers paramètres lexicaux et syntaxiques, en comparant d’abord le corpus, pris dans son ensemble, à un corpus de textes non traduits, puis en comparant entre eux les différents sous-corpus de traductions. Le premier type de comparaison (externe) a pour objectif de mettre en évidence les caractéristiques des traductions en général, le second (interne) de dégager les spécificités de chaque groupe de traductions.

The material study of La Famille Soler through non-invasive imaging, molecular, structural and elemental techniques, permitted a relevant re-examination of this singular blue period painting, which is considered as the earliest Picasso’s version of Le déjeuner sur l’herbe by E. Manet. On the one hand, it was concluded that the underlying landscape painted by Vidal in 1903 referred to Manet’s masterpiece. On the other hand, it was assumed that the cubist sketch undertaken by Picasso in 1912, prior to the current blue background, consists of an uncompleted transformation of Vidal’s landscape into synthetic cubism. Additionally, the main pigments associated to the underlying compositions were successfully identified. [less ▲]

Hydrodistillation assisted by microwave (HDAM) and Head space solid phase micro-extraction (HSSPME) of Myristica fragrans houtt (MF) were investigated. A kinetic study was performed for MF seeds using two techniques (HDAM: Hydrodistillation assisted by microwave and SDAM: steam distillation assisted by microwave). The effect of the cryogenic grinding (CG) showed differences in yields and composition of volatile oils compared to the simple grinding (SG). HDAM–SG (3.4%) and SDAM–SG (2.55%) allowed extraction of substantial amounts of volatile oils in less time compared with HDAM–CG (4.75%) and SDAM–CG (3.8%). The kinetic study (differential and accumulated yields) of essential oil extraction was quantitatively and qualitatively performed showing a significant variation of composition with the extraction time, especially for accumulated yields such as sabinene (31.48–38.78%), α-pinene (12.74–14.09%) and β-pinene (10.01–12.11%). Similarly, the HS-SPME–GC–MS analysis showed also a significant variation of MF seeds volatile composition according some parameters as the type of fibre coating (PDMS: Polydimethylsiloxane and PDMS– DVB: Polydimethylsiloxane divenylbenzene), particle size, grinding mode and the mass used. The chemical groups (monoterpenoids, aliphatic and aromatic alcohols and esters) showed specific behaviour in SPME analysis. SPME sampling parameters were optimized for these components. [less ▲]

This paper uses institutional theory to highlight different patterns of cross-sector collaboration from the perspective of social enterprises. Specifically, it explores how and why social enterprises interact with mainstream businesses and to what extent their collaboration patterns reflect a vision of how their social mission should be implemented and institutionalized. The empirical analysis is derived from a qualitative study of ‘fair trade’ – a hybrid model created by social enterprises and using market mechanisms to support small-scale producers in developing countries and to advocate for changes in international trading practices. The findings highlight three strategies used by fair trade social enterprises to manage their interactions with mainstream businesses: sector solidarity, selective engagement, and active appropriation. This paper suggests that each strategy is motivated by a different vision of how best to articulate the social mission of fair trade via specific types of collaborations. It also notes how each vision has a distinct pattern of institutionalization at the field level. This paper adds to the emergent literatures on social enterprise and social entrepreneurship, fair trade, cross-sector collaboration and hybrid organizing. [less ▲]

The purpose of this note is to focus on the finiteness of the weighted likelihood estimator (WLE) of ability in the context of dichotomous and polytomous item response theory (IRT) models. It is established that the WLE always returns finite ability estimates. This general result is valid for dichotomous (one-, two-, three- and four-parameter logistic) IRT models, the class of polytomous difference models and divide-by-total models, independently of the number of items, the item parameters and the response patterns. Further implications of this result are outlined. [less ▲]

In Nile tilapia Oreochromis niloticus, phenotypic males and females with different sexual genotypes (XX, XY, YY) have particular behavioural and physiological traits. Compared to natural XX females and XY males, XY and YY females, and XX males expressed higher level of aggressiveness that could be related to higher levels of 17β-oestradiol and 11-ketotestosterone respectively. Our results suggest that the presence of a Y chromosome increases aggressiveness in females. However, since the same relationship between aggressiveness and the Y chromosome is not observed in males, we can hypothesize that the differences in aggressiveness are not directly dependent on the genotype but on the sex reversal procedures applied on young fry during their sexual differentiation to produce these breeders. These hormonal treatments could have permanently modified the development of the brain and consequently influenced the behaviour of adults independently of their genotype. In both hypotheses (genotype or sex reversal influence), the causes of behavioural modifications have to be searched in an early modification of the brain sexual differentiation. [less ▲]

The synaptic vesicle glycoprotein 2A (SV2A), a protein essential to the proper nervous system function, is found in presynaptic vesicles. Thus, SV2A targeting, using dedicated radiotracers combined with positron emission tomography (PET), allows the assessment of synaptic density in the living brain. The first-in-class fluorinated SV2A specific radioligand, [18F]UCB-H, is now available at high-activity through an efficient radiosynthesis compliant with the current good manufacturing practices (cGMP). We report here a non-invasive method to quantify [18F]UCB-H binding in rat brain with microPET. Validation study in rats confirmed the need of high enantiomeric purity to target SV2A in vivo. We demonstrated the reliability of a population-based input function to quantify SV2A in preclinical microPET setting. Finally, we investigated the in vivo metabolism of [18F]UCB-H and confirmed the negligible amount of radiometabolites in the rat brain. Hence, the in vivo quantification of SV2A using [18F]UCB-H microPET seems a promising tool for the assessment of the synaptic density in the rat brain, and opens the way for longitudinal follow-up in neurodegenerative diseases rodents’ models.

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

Of all the royal families of ancient or modern fame, few are as iconic as the eighteenth dynasty of pharaohs of the New Kingdom of Egypt, whose opulence and deeds we are still familiar to nearly 3,500 years after their time. Tenth pharaoh of this dynasty and father of Tutankhamun, Akhenaten (Amenhotep/Amenhotep IV) still fascinates Egyptologists and history lovers through the many questions surrounding his atypical rule. One of the most striking aspects of the so-called Amarna period concerns the representations of the pharaoh himself, very confusing compared to the traditional iconography of the New Kingdom. These intriguing portraits of Pharaoh raised a whole lot of medical assumptions, more or less substantiated. We review here the main theories developed throughout history. [less ▲]

Humans have the remarkable ability to mentally travel through past and future times. However, while memory for the times of past events has been much investigated, little is known about how imagined future events are temporally located. Using a think-aloud protocol, we found that the temporal location of past and future events is rarely directly accessed, but instead mostly relies on reconstructive and inferential strategies. References to lifetime periods and factual knowledge (about the self, others, and the world) were most frequently used to determine the temporal location of both past and future events. Event details (e.g., places, persons, or weather conditions) were also used, but mainly for past events. Finally, the results showed that events whose temporal location was directly accessed were judged more important for personal goals. Together, these findings shed new light on the mechanisms involved in locating personal events in past and future times. [less ▲]

In order to differentiate from competitors in terms of customer service, warehouses accept late orders while providing delivery in a quick and timely way. This trend leads to a reduced time to pick an order. This paper introduces workload forecasting in a warehouse context, in particular a zone picking warehouse. Improved workforce planning can contribute to an effective and efficient order picking process. Most order picking publications treat demand as known in advance. As warehouses accept late orders, the assumption of a constant given demand is questioned in this paper. The objective of this study is to present time series forecasting models that perform well in a zone picking warehouse. A real-life case study demonstrates the value of applying time series forecasting models to forecast the daily number of order lines. The forecast of order lines, along with order pickers’ productivity, can be used by warehouse supervisors to determine the daily required number of order pickers, as well as the allocation of order pickers across warehouse zones. Time series are applied on an aggregated level, as well as on a disaggregated zone level. Both bottom-up and top-down approaches are evaluated in order to find the best-performing forecasting method.

Surface-enhanced Raman spectroscopy (SERS) is a sensitive analytical tool used in the pharmaceutical field in recent years. SERS keeps all the advantages of classical Raman spectroscopy while being is more sensitive allowing its use for the detection and the quantification of low-dose substances contained in pharmaceutical samples. However, the analytical performance of SERS is limited due to the difficulty to implement a quantitative methodology correctly validated. Nevertheless, some studies reported the development of SERS quantitative methods especially in pharmaceutical approaches. In this context, this review presents the main concepts of the SERS technique. The different steps that need to be applied to develop a SERS quantitative method are also deeply described. The last part of the present manuscript gives a critical overview of the different SERS pharmaceutical applications that were developed for a non-exhaustive list of pharmaceutical compounds with the aim to highlights the validation criteria for each application.

Starting early 2015, the fusion-based additive manufacturing of Al alloys has been developing at an ever faster pace after undergoing a comparatively slow start with respect to other metallic materials. This paper reviews the recent developments with the aim of identifying major challenges and opportunities for future work. Laser Beam Melting proves the most useful technique for the additive fabrication of Al components with strongly out-of-equilibrium microstructures and potentially enhanced mechanical behavior. Laser Cladding is also promising for specific applications such as repairs and coatings. However, a deeper understanding of the thermal history during fabrication is still needed to further optimize the microstructures and usage properties. The design of new high strength alloys and of Al-matrix composites, and the development of better adapted post-processing procedures to take greater advantage of the specificities of fusion-based additive techniques are two other important issues in view of reaching the full potential of additive Al components.

Supplementation of post-weaning diets with exogenous enzymes has been suggested to control post-weaning syndrome, by compensating for the under-developed endogenous enzyme secretory capacity and increasing nutrient digestibility in newly weaned pigs. The effect of in-feed enzymes in improving gut maturation, growth and/or health in weaned piglets is not always consistent. A systematic review and a meta-analysis were therefore conducted to determine which exogenous enzymes are most consistent in improving piglet growth and digestibility when supplemented to post-weaning diets. The mean difference effect of enzyme supplementation on growth and digestibility of dry matter (DM), gross energy (GE), crude protein (CP), and P digestibility was calculated for each study and this was used as the effect size estimate in the meta-analysis. The impact of feed enzyme supplementation on intestinal health and bone mineralization was also discussed where information was available in the literature. From a total of 90 studies included in the metaanalysis, G:F was improved in 55, remained un-changed in 28 and deteriorated in 7, in response to enzyme supplementation. Average daily gain, average daily feed intake (ADFI) and G:F was improved when phytase was supplemented in the diet. Phosphorous digestibility was increased with phytase supplementation while GE digestibility was reduced. Dietary phytase supplementation increased bone mineralization in pigs fed diets with a reduced Pcontent. Supplementation with multi-enzyme complexes increased DM and CP digestibility. In conclusion, the most consistent improvement in piglet growth, P digestibility and bone mineralization were found due to exogenous phytase supplementation. Supplementation with xylanase alone or in combination with β-glucanase had inconsistent effects on piglet growth and nutrient digestibility. The most consistent improvements in growth and nutrient digestibility due to supplementation with multi-enzymes complexes were found when mannanase and/or protease were included in the complex.

En prenant l'exemple de l'expression prépositionnelle ou non du datif en ancien français et en français moderne (complément des verbes _donner_, _aider_, et _pardonner_), nous montrons comment les polygraphes peuvent être employés pour montrer géométriquement la différence entre une préposition obligatoire et une préposition facultative. Le potentiel de ces structures permet également de visualiser l'évolution et de comparer le comportement des lexèmes. [less ▲]

Aim: Continuous pain occurs routinely, even after invasive procedures, or inflammation and surgery, but clinical practices associated with assessments of continuous pain remain unknown. Methods: A prospective cohort study in 243 Neonatal Intensive Care Units (NICUs) from 18 European countries recorded frequency of pain assessments, use of mechanical ventilation, sedation, analgesia, or neuromuscular blockade for each neonate upto 28 days after NICU admission. Results: Only 2113/6648 (31·8%) of neonates received assessments of continuous pain, occurring variably among tracheal ventilation (TrV, 46·0%), noninvasive ventilation (NiV, 35· 0%), and no ventilation (NoV, 20· 1%) groups (p<0· 001). Daily assessments for continuous pain occurred in only 10·4% of all neonates (TrV: 14· 0%, NiV: 10· 7%, NoV: 7· 6%; p<0· 001). More frequent assessments of continuous pain occurred in NICUs with pain guidelines, nursing champions, and surgical admissions prompted (all p<0·01), and for newborns <32 weeks gestational age, those requiring ventilation, or opioids, sedatives-hypnotics, general anesthetics (O-SH-GA) (all p<0·001), or surgery (p=0· 028). Use of O-SH-GA drugs increased the odds for pain assessment in the TrV (OR:1· 60, p<0·001) and NiV groups (OR:1·40, p<0· 001). Conclusion: Assessments of continuous pain occurred in less than one-third of NICU admissions, and daily in only 10% of neonates. NICU clinical practices should consider including routine assessments of continuous pain in newborns. [less ▲]

Estrogens derived from brain testosterone aromatization (neuro-estrogens) are critical for the activation of male sexual behavior. Their effects on this behavior are typically associated with long-term changes in circulating levels of testosterone and the transcriptional activity of their liganded nuclear receptors. According to this view, neuro-estrogens would prime the neural circuits controlling the long-term expression of behavior, which would then be acutely regulated by neurotransmitter systems conveying information from the social environment. In parallel, neuro-estrogens are also able to produce much faster effects than previously anticipated. Our recent investigations in Japanese quail revealed an interesting dichotomy in the regulation of male sexual behavior by membrane- and nuclear-initiated estrogen signaling providing respectively an acute modulation of sexual motivation and a long-term control of the capacity to display the copulatory sequence. In parallel, a similar dichotomy applies to the regulation of brain aromatase whose expression depends on the transcriptional activity of testosterone metabolites while its enzymatic activity is rapidly regulated in a region- and context-dependent manner. Recent evidences suggest that rapid changes in sexual motivation result from rapid changes in local estrogen production. Together, these data support the idea that the acute regulation of some aspects of male sexual behavior depends not only on classical neurotransmitter systems, but also on rapid and spatially restricted changes in local estrogen availability. The existing literature suggests that this acute regulation by neuro-estrogens of the motivational aspects of behavior could be generalized to other systems such as singing behavior in songbirds.

Microgravity, confinement, isolation, and immobilization are just some of the features astronauts have to cope with during space missions. Consequently, long-duration space travel can have detrimental effects on human physiology. Although research has focused on the cardiovascular and musculoskeletal system in particular, the exact impact of spaceflight on the human central nervous system remains to be determined. Previous studies have reported psychological problems, cephalic fluid shifts, neurovestibular problems, and cognitive alterations, but there is paucity in the knowledge of the underlying neural substrates. Previous space analogue studies and preliminary spaceflight studies have shown an involvement of the cerebellum, cortical sensorimotor, and somatosensory areas and the vestibular pathways. Extending this knowledge is crucial, especially in view of long-duration interplanetary missions (e.g., Mars missions) and space tourism. In addition, the acquired insight could be relevant for vestibular patients, patients with neurodegenerative disorders, as well as the elderly population, coping with multisensory deficit syndromes, immobilization, and inactivity.

While it goes undisputed that international criminal tribunals (ICTs) are, in general terms, bound to respect human rights standards, there is no consensus on whether their obligations should be identical in scope to those of national criminal tribunals. Most commentators seem to value the idea of equality in protection for international and domestic defendants alike. Yet, according to others, the human rights obligations of ICTs should be contextualised, that is, adapted to the specificities of international justice – and most critically to the gravity of international crimes. This article seeks to shed some light on this debate. It does so, in particular, by pointing out the intrinsic flexibility of human rights, and by drawing on the practice of the European Court of Human Rights with respect to gravity-based contextualism.

In this paper I want to create a presumption in favor of a nonreductive analysis of emotional phenomenology. The presumption relies on the claim that none of the nonemotional elements which are usually regarded as constitutive of emotional phenomenology may reasonably be considered responsible for the evaluative character of the latter. In section 1 I suggest this is true of cognitive elements, arguing that so-called ‘evaluative’ judgments usually result from emotional, evaluative attitudes, and should not be conflated with them. In section 2 I argue the same holds true for conative attitudes (desires and acts of the will). And in section 3 I briefly mention some salient aspects of the version of nonreductive analysis I lean toward. [less ▲]

Measuring serum creatinine is cheap and commonly done in daily practice. However, interpretation of serum creatinine results is not always easy. In this review, we will briefly remind the physiological limitations of serum creatinine due notably to its tubular secretion and the influence of muscular mass or protein intake on its concentration. We mainly focus on the analytical limitations of serum creatinine, insisting on important concept such as reference intervals, standardization (and IDMS traceability), analytical interferences, analytical coefficient of variation (CV), biological CV and critical difference. Because the relationship between serum creatinine and glomerular filtration rate is hyperbolic, all these CVs will impact not only the precision of serum creatinine but still more the precision of different creatinine-based equations, especially in low or normal-low creatinine levels (or high or normal-high glomerular filtration rate range).

Distinct gap features in the nearest protoplanetary disk, TW Hya (distance of 59.5$\pm$0.9 pc), may be signposts of ongoing planet formation. We performed long-exposure thermal infrared coronagraphic imaging observations to search for accreting planets especially within dust gaps previously detected in scattered light and submm-wave thermal emission. Three nights of observations with the Keck/NIRC2 vortex coronagraph in $L^\prime$ (3.4-4.1$\mu$m) did not reveal any statistically significant point sources. We thereby set strict upper limits on the masses of non-accreting planets. In the four most prominent disk gaps at 24, 41, 47, and 88 au, we obtain upper mass limits of 1.6-2.3, 1.1-1.6, 1.1-1.5, and 1.0-1.2 Jupiter masses ($M_J$) assuming an age range of 7-10 Myr for TW Hya. These limits correspond to the contrast at 95\% completeness (true positive fraction of 0.95) with a 1\% chance of a false positive within $1^{\prime\prime}$ of the star. We also approximate an upper limit on the product of planet mass and planetary accretion rate of $M_p\dot{M}\lesssim10^{-8} M_J^2/yr$ implying that any putative $\sim0.1 M_J$ planet, which could be responsible for opening the 24 au gap, is presently accreting at rates insufficient to build up a Jupiter mass within TW Hya's pre-main sequence lifetime.

Shallow reservoirs are often used as sediment traps or storage basins, in which sedimentation depends on the flow pattern: Short rectangular reservoirs reveal a straight jet from inlet to outlet with on both sides identical recirculation zones. In longer reservoirs, the main jet reattaches to the side of the reservoir leading to a small and a large recirculation zone. Previous studies found an empirical geometric relation describing the switch between these two flow patterns. In this study, we demonstrate, with a simple analytical model, that this switch coincides with a maximization of energy dissipation in the shear layer between the main jet and recirculation zones: Short reservoirs dissipate more energy when the flow pattern is symmetric, while longer reservoirs dissipate more energy with an asymmetric pattern. This approach enables to predict the flow patterns without detailed knowledge of small scale processes, potentially useful in the early phase of reservoir design. [less ▲]

A linear oscillator simultaneously subjected to stochastic forcing and parametric excitation is considered. The time required for this system to evolve from a low initial energy level until a higher energy state for the first time is a random variable. Its expectation satisfies the Pontryagin equation of the problem, which is solved with the asymptotic expansion method developed by Khasminskii. This allowed deriving closed-form expressions for the expected first passage time. A comprehensive parameter analysis of these solutions is performed. Beside identifying the important dimensionless groups governing the problem, it also highlights three important regimes which are called incubation, multiplicative and additive because of their specific features. Those three regimes are discussed with the parameters of the problem. [less ▲]

Understanding the potential drought characteristics under climate change is essential for reducing vulnerability and establishing adaptation strategies, especially in the Huang-Huai-Hai Plain (3H Plain) which is the grain production base in China. In this paper, the variation of drought characteristics including drought event frequency, duration, severity and intensity for the past 50 years (1961-2010) and future scenarios (2010-2099) based on observed meteorological data and RCP 8.5 projections were investigated, respectively. Firstly, the applicability of three climatic drought indices including the Standardized Precipitation Index (SPI), the Standardized Precipitation Evapotranspiration Index based on the Penman–Monteith equation (SPEI-PM) and the Thornthwaite equation (SPEI-TH) were compared in tracing recorded agricultural drought areas. Then, the drought characteristics including drought event, duration, severity and intensity using “run theory” was analyzed for both historical observations and future RCP 8.5 scenarios based on the proper index. Correlation analysis between drought indexes and agricultural drought areas showed that SPEI-PM performed better than SPI and SPEI-TH in the 3H Plain. Based on the results of SPEI-PM, droughts over the past 50 years have experienced reduced drought with shorter durations, and weaker severity and intensity. However, for the future RCP 8.5 scenario, drought is predicted to rise in frequency, duration, severity and intensity from 2010-2099 although drought components during the 2010-2039 were milder compared to historical conditions. This study highlights that the estimations for atmospheric evaporative demand would bring in differences in long term drought trend of drought indexes and consequently the applicability in 3H Plain. The results of this paper can help inform researchers and local policy makers to establish drought risk management strategies. [less ▲]

The famous Doignon-Bell-Scarf theorem is a Helly-type result about the existence of integer solutions to systems of linear inequalities. The purpose of this paper is to present the following quantitative generalization: Given an integer k, we prove that there exists a constant c(n,k), depending only on the dimension n and on the number k, such that if a bounded polyhedron {x in R^n : Ax <= b} contains exactly k integer points, then there exists a subset of the rows, of cardinality no more than c(n,k), defining a polyhedron that contains exactly the same k integer points. In this case c(n,0)=2^n as in the original case of Doignon-Bell-Scarf for infeasible systems of inequalities. We work on both upper and lower bounds for the constant c(n,k) and discuss some consequences, including a Clarkson-style algorithm to find the l-th best solution of an integer program with respect to the ordering induced by the objective function.

Dans le dernier quart du XVIe siècle, Philippe II d’Espagne est à la tête de l’ensemble territorial le plus puissant d’Europe. Fils préféré de l’Église romaine et souverain reconnu d’une grande partie de l’Italie, il exerce une influence considérable sur la papauté à travers l’action de son ambassadeur espagnol résidant près le Saint-Siège. Ce dernier a pour tâche d’étendre le réseau des alliés au sein de la Curie. Il chapeaute aussi les différents services diplomatiques et ecclésiastiques des États de la monarchie présents dans la cité des papes . Si elle conserve une certaine autonomie, la légation des Pays-Bas et de la Franche-Comté près le Saint-Siège – conduite par l’agent Laurent du Blioul de 1573 à 1598 – est également soumise à la volonté de cet envoyé. Ce n’est d’ailleurs pas un hasard si l’étude de la légation à l’époque du règne de Philippe II a peu passionné les historiens . Effacée derrière la puissance de l’ambassadeur espagnol, celle-ci semble être un piètre avatar des services ecclésiastiques et diplomatiques dépêchés à Rome par les ducs de Bourgogne , Philippe le Beau ou les archiducs Albert et Isabelle . Or, si, aux temps de Laurent du Blioul, la légation, considérée en tant qu’actrice isolée dans le paysage romain, joue un rôle modeste qui se cantonne au suivi des affaires ecclésiastiques provenant des Pays-Bas et de la Franche-Comté, il faut envisager qu’elle fait partie intégrante d’une toile religieuse, diplomatique, sociale et politique plus vaste tissée à Rome par le roi Philippe II et ses agents. Dépassant les seuls intérêts des Pays-Bas, l’étude de cette institution conduit à appréhender tout un pan de la stratégie politique habsbourgeoise. L’imbrication de la légation dans le théâtre diplomatique espagnol à Rome a deux facettes : si, d’une part, elle limite les prérogatives institutionnelles de l’agent du Blioul, d’autre part, elle favorise régulièrement l’efficacité de son action.

Movement patterns during landing have been suggested to be related to injury risk. The purpose of this study was to determine the inter-session reliability of kinematic variables and ground reaction forces during landing in a population of male recreational athletes after a counter movement jump. Both unipodal and bipodal landings were evaluated. Furthermore, the possibility to improve landing reliability with a verbal instruction was also studied. Twenty- four male volunteers with no history of lower-extremity trauma were randomly assigned to two groups (with and without verbal landing instruction). An optoelectronic 3D system and force plates were used to measure the lower-limb joint angles and the ground reaction forces during landing. Intraclass correlation values show moderate to excellent inter-session reliability for the bipodal task (ICC average: 0.80, range: 0.46 to 0.97) and poor to excellent reliability for the unipodal task (ICC average: >0.75, range: 0.20 to 0.95). However, large standard errors of measurement values at the ankle joint at impact (27.6 ± 11.5°) and for the vertical ground reaction forces (394 ± 1091 N) show that some variables may not be usable in practice. The verbal instruction had a negative effect on the reliability of unipodal landing but improved the reliability of bipodal landing. These findings show that the reliability of a landing task is influenced by its motor complexity as well as the instruction given to the subject. [less ▲]

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [less ▲]

Alfred Einstein soulignait en 1949 qu’« à Naples comme à Palerme, le baroque le plus extravagant fleurissait à l’église, à la cour et dans la musique ». En effet, la culture de la Méditerranée – immémorial carrefour de nombreuses civilisations – a donné naissance à un monde musical riche et singulier dans la période qui court de la fin de la Renaissance au début du Baroque et sur lequel il reste beaucoup à découvrir. Il en est de même pour Rome : la richesse de l’activité musicale s’y présentait sous les formes les plus éclectiques. La Ville Eternelle était alors en effet la cour la plus importante de la Péninsule, foyer culturel majeur et porte de l’Italie méridionale. Nous pouvons constater un récent regain d’intérêt pour la recherche archivistique et historique qui a permis, à travers de nombreux travaux et colloques, de jeter un regard neuf sur le milieu musical et culturel romain et méditerranéen de cette époque (musique vocale profane et sacrée, musique instrumentale, théâtre, institutions musicales, etc.).

The effects of hydrocolloids (Hydroxypropylmethylcellulose (HPMC), Carboxymethylcellulose (CMC), Xanthan gum (XG), and Apple pectin (AP)) at different concentrations on dough thermo-mechanical properties and in vitro starch digestibility of gluten-free potato steamed bread were investigated. Results showed that hydrocolloids addition significantly increased the gelatinization temperature (from 52.0 to 64.2 °C) and water absorption (from 56.22 to 66.50 %) of potato dough. Moreover, hydrocolloids may be interacted with protein and starch, the density of potato protein bands was decreased by hydrocolloids addition, the reason might be that higher molecular weight complexes might be formed between proteins-hydrocolloids or proteins-proteins, thus change the protein solubility. Furthermore, steamed breads with hydrocolloids presented higher specific volume and lower hardness, and the rapidly digestible starch and estimated glycemic index were significantly decreased from 45.51 to 20.64, from 69.54 to 55.17, respectively. In conclusion, HPMC and XG could be used as improvers in the gluten-free potato steamed bread. [less ▲]

Antarctic sea-ice bacterial community composition and dynamics in various developmental stages were investigated during the austral winter in 2013. Thick snow cover likely insulated the ice, leading to high (o4 μg l–1) chlorophyll-a (chl-a) concentrations and consequent bacterial production. Typical sea-ice bacterial genera, for example, Octadecabacter, Polaribacter and Glaciecola, often abundant in spring and summer during the sea-ice algal bloom, predominated in the communities. The variability in bacterial community composition in the different ice types was mainly explained by the chl-a concentrations, suggesting that as in spring and summer sea ice, the sea-ice bacteria and algae may also be coupled during the Antarctic winter. Coupling between the bacterial community and sea-ice algae was further supported by significant correlations between bacterial abundance and production with chl-a. In addition, sulphate-reducing bacteria (for example, Desulforhopalus) together with odour of H2S were observed in thick, apparently anoxic ice, suggesting that the development of the anaerobic bacterial community may occur in sea ice under suitable conditions. In all, the results show that bacterial community in Antarctic sea ice can stay active throughout the winter period and thus possible future warming of sea ice and consequent increase in bacterial production may lead to changes in bacteria-mediated processes in the Antarctic sea-ice zone.

We study retirement incentives with an augmented reduced form option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentive and household composition.

Massive runaway stars produce bow shocks through the interaction of their winds with the interstellar medium, with the prospect for particle acceleration by the shocks. These objects are consequently candidates for non-thermal emission. Our aim is to investigate the X-ray emission from these sources. We observed with XMM-Newton a sample of 5 bow shock runaways, which constitutes a significant improvement of the sample of bow shock runaways studied in X-rays so far. A careful analysis of the data did not reveal any X-ray emission related to the bow shocks. However, X-ray emission from the stars is detected, in agreement with the expected thermal emission from stellar winds. On the basis of background measurements we derive conservative upper limits between 0.3 and 10 keV on the bow shocks emission. Using a simple radiation model, these limits together with radio upper limits allow us to constrain some of the main physical quantities involved in the non-thermal emission processes, such as the magnetic field strength and the amount of incident infrared photons. The reasons likely responsible for the non-detection of non-thermal radiation are discussed. Finally, using energy budget arguments, we investigate the detectability of inverse Compton X-rays in a more extended sample of catalogued runaway star bow shocks. From our analysis we conclude that a clear identification of non-thermal X-rays from massive runaway bow shocks requires one order of magnitude (or higher) sensitivity improvement with respect to present observatories.

Tetrapod limbs are serially homologous structures that represent a particularly interesting model for studies on morphological integration, i.e. the tendency of developmental systems to produce correlated variation. In newts, limbs develop at an early larval stage and grow continuously, including after the habitat transition from water to land following metamorphosis. However, aquatic and terrestrial environments impose different constraints and locomotor modes that could affect patterns of morphological integration and evolvability. We hypothesize that this would be the case for alternative heterochronic morphs in newts, i.e. aquatic paedomorphs that keep gills at the adult stage and adult metamorphs that are able to disperse on land. To this end, we analysed patterns and strengths of correlations between homologous skeletal elements of the fore- and hindlimbs as well as among skeletal elements within limbs in both phenotypes in the alpine newt, Ichthyosaura alpestris. Our results showed that metamorphs and paedomorphs had similar, general patterns of limb integration. Partial correlations between homologous limb elements and within limb elements were higher in paedomorphs when compared to metamorphs. Decrease in partial correlation between homologous limb elements in metamorphs is accompanied with a higher evolvability of the terrestrial morph. All these results indicate that environmental demands shaped the patterns of morphological integration of alpine newt limbs and that the observed diversity in correlation structure could be related to a qualitative difference in the modes of locomotion between the morphs.

A nitrogen (N) balance digestion trial was conducted to determine the protein requirement of collared peccaries (Pecari tajacu). In a 4 × 4 Latin square design, four captive adult male peccaries were fed four isoenergy diets containing four different levels of N (11.7, 16.3, 22.8, and 26.7 g N/kg of dry matter—DM). After 15 days of adaptation, a total collection of feces and urine was carried out for five consecutive days. Regression analyses between N intake and N in feces and urine allowed to calculate the metabolic fecal nitrogen (MFN = 2.3 g N/kg of dry matter intake—DMI) and daily endogenous urinary N (EUN = 185 mg N/kg0.75). Likewise, by regression analyses between consumption of nitrogen and the nitrogen balance (NB = N ingested − N excreted, mg N/kg0.75), a daily requirement of 514 mg N/kg0.75 was calculated. Therefore, if food intake is unrestricted, collared peccaries require a minimumin their diet of about 5.4% crude protein on DM basis. These values are almost as low as those found for browsing and frugivorous wild ruminants, which reinforce the proposition that peccaries’ digestive physiology is nearer to that of domestic and wild ruminants than domestic pigs. This relatively low protein requirement of collared peccary and its great ability to digest protein reveal the relevance of the forestomach for the species on nitrogen/protein metabolism and allow the use of diets with lower crude protein levels than the commercial ones used for the domestic pig, which reduces feed costs.

In liberalized network industries, competitors can either compete for service using the existing infrastructure (access) or deploy their own capacity (bypass). We revisit this make-or-buy problem making two contributions to the literature. First we analyze both the profit maximizing behavior of an incumbent and the welfare maximizing behavior when the entrant chooses between access and bypass. Second, we extend the baseline model studied in the literature by allowing for fixed costs of network installation. By analogy to the literature on strategic entry deterrence, we distinguish three regimes of blockaded bypass, deterred bypass and accommodated bypass depending on the entrant's unit cost. We show that the make-or-buy decision of the entrant is not necessarily technologically efficient: when bypass is chosen, it is always the cheapest option but access may be chosen when it is not cost effective.

INTRODUCTION: Vitamin D insufficiency, defined by a 25-hydroxyvitamin D (25OHD) serum concentration<20ng/mL, is highly frequent in the French general population, especially between November and April. The aim of this study was to evaluate whether 80,000 IU vitamin D3 every month during this period of the year was able to maintain a 25OHD level between 20 and 60ng/mL in apparently healthy subjects whatever their basal vitamin D status. METHODS: Ninety-eight subjects volunteered to receive an 80,000 IU vitamin D3 dose every month between November 2014 and April 2015. Serum 25OHD, calcemia and calciuria were measured just before the first dose (Month 0), just before the 4th dose (M4), and one month after the 6th dose (M7). RESULTS: At M0, 25OHD was 17.5+/-9.5ng/mL. Sixty subjects (61.2%) had a 25OHD<20ng/mL and 25 (25.5%) had a 25OHD<10ng/mL. 25OHD increased significantly at M4 (35.3+/-8.0ng/mL) and M7 (40.1+/-8.5) without change in calcemia and calciuria. At M4, 2 subjects had a 25OHD slightly below 20ng/mL (17.6 and 19.7ng/mL), and none had a concentration>60ng/mL. At M7, all had a serum 25OHD>20ng/mL and 2 subjects had a value slightly above 60ng/mL (62.1 and 63.2ng/mL). CONCLUSION: A monthly supplementation with 80,000 IU vitamin D3 between November and April corrected vitamin D insufficiency in subjects in whom it was initially very frequent, without overdosing. This protocol is simple, safe and costless, and can be easily implemented when physicians detect risk factors for hypovitaminosis D in patients for whom a 25OHD measurement is not indicated.

Eleven samples of the traditional date product " Btana" prepared by direct (DBM) and indirect method (UBM) were analysed to characterize their bacterial diversity. A total of 42 representative isolates have been chosen for molecular identification. 16S rRNA gene sequencing revealed the presence of 20 species within 30.9% belonged to the genus Bacillus, 28.6% of the Staphylococcus, and Enterococcus genus. Within the minority represented species, two isolates were identified as Paenibacillus (isolated from UBM exclusively), Streptococci salivarius, Lactobacillus sakei and Klebsiella pneumoniae. Preliminary results indicate that IBM is more selective for spore former bacilli contrary to DBM that show more diversity in the bacterial flora with a prevalence of Enterococcus. API ZYM test showed that the bacilli species have a weak hydrolase activity. [less ▲]

Objectives: (1) To investigate music theory teachers’ professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. Methods: Using voice dosimetry, 13 music theory teachers were monitored for one workweek. Parameters analysed were voice SPL, F0, phonation time, vocal loading index (VLI) and noise SPL. Spearman’s correlation was used to correlate vocal loading parameters (voice SPL, F0 and phonation time) and noise SPL. Each day, subjects self-assessed their voice using visual analogue scales. VLI and self-evaluation data were correlated using Spearman’s correlation. Results: Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time and females’ F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue and amount of singing and speaking voice produced. Conclusions: Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders. Correlations between VLI and self-assessments suggest that these teachers are well-aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analogue scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users. [less ▲]
