Perception olfactive et régulation émotionnelle : Approches psychophysique, psychophysiologique et par imagerie cérébrale

Ces travaux ont pour but d'etudier des mecanismes centraux de l'olfaction, et la maniere dont ils sont integres dans les processus de regulationemotionnelle. Les strategies de distraction et de reevaluation ont fait l'objet de deux experiences distinctes en IRMf, dans lesquelles les sujets devaientdiminuer l'intensite d'emotions suscitees par des odeurs. Dans une troisieme experience, des donnees psychophysiques et psychophysiologiques ont etecollectees pour evaluer la capacite d'une odeur agreable a reguler un sentiment negatif prealablement induit par uneimage desagreable.Les resultats montrent que la regulation d'emotions induites par des odeurs mobilise des aires cerebrales decrites dans les etudes utilisant du materielvisuel (cortex prefrontal, lobule parietal inferieur, gyrus temporal moyen) mais aussi d'autres plus specifiques a cette modalite sensorielle (insula, gyrusfusiforme, gyrus lingual). De plus, le cortex prefrontal semble moduler certaines aires du cortex olfactif comme le cortex piriforme et le cortexorbitofrontal lorsque les sujets utilisent une strategie de distraction. Les donnees issues de la troisieme experience revelent egalement qu'une odeuragreable permet de diminuer l'impact d'un affect negatif prealablement induit, tant au niveau subjectif que psychophysiologique.Par consequent, il semble exister chez l'Homme une reelle capacite a la regulation des emotions induites par des odeurs. Ce processus met enjeu desregions habituellement decrites pour la regulation d'emotions induites par des stimuli visuels, mais egalement d'autres aires plus specifques.De plus, les odeurs elles-memes sont capables de reguler une emotion negative.
An Improvement Proposal to the Static Friction Model

Friction is a force acting against the relative motion between two surfaces in contact. This phenomenon is present in all mechanical systems and has a great impact on the control area. The design of mechatronic systems and the compensation techniques require a broad knowledge of the effects that friction produces. The phenomenon has two well-defined phases: static friction presents before the motion between the surfaces in contact is clearly visible, while kinetic friction appears when that motion at large scale has already started. There are different friction models for each of those phases. In this work we propose an improvement to the static friction models, which consist in assuming that the maximum static friction coefficient is no more a constant but a function of the rate of change of the external force that produces the motion. After explaining and justifying the proposal, the procedure for obtaining the parameters of the new model is mentioned. At the end, an experimental study on a direct-drive motor allows us to validate the proposed model.
Nomadicity – bug or feature?

This paper takes an auto-ethnographic approach, focusing on my own nomadic work practices as part of a sabbatical year. A diary excerpt is used to illustrate an example of working “anywhere, anytime” motivated partly by deadlines, but also by project interdependencies, as well as by urgency and by the desire to make space for some leisure time. Work happened seamlessly at different places, mobilizing various artefacts and involving various collaborators as a result of coordination efforts ’over trajectories of time and distributed in space’ (Rossitto and Eklundh, 2007).
PHYSIO-CHEMICAL CHANGES DURING POST HARVEST HANDLING OF ONION (Allium cepa L.)–A REVIEW

Harvested onion bulbs under goes several physio-chemical changes like increase in respiration, physiological loss in weight (PLW), rotting and sprouting. Chemical changes in stored of onions include dry matter content, pungency, abscisic acid and fructans concentration. The seasonal differences were observed in the weight of the onions, dry matter content, glucose and total carbohydrates. Even some of the pre-harvest cultural practices like nutrition, maturity, growth regulator spraying etc and also post harvest curing would extend shelf life of onion bulbs. Onion storage in ventilation condition is satisfactory when the temperature is maintained between 25oC to 30oC with a relative humidity 65 to 70 per cent.
Summer and winter drought in a cold desert ecosystem ( Colorado Plateau ) part I : effects on soil water and plant water uptake

We investigated the effects of winter and summer drought on plants of the Colorado Plateau in western North America. This winter-cold, summer-hot desert region receives both winter and summer precipitation. Droughts were imposed for two consecutive years using rainout shelters. Here, we examine drought effects on the hydrologic interactions between plants and soil. We chose three perennial species for this study, representing different rooting patterns and responsiveness to precipitation pulses: Oryzopsis hymenoides, a perennial bunch grass with shallow roots; Gutierrezia sarothrae, a subshrub with dimorphic roots; and Ceratoides lanata, a predominantly deep-rooted woody shrub. Drought effects on plant water status were qualitatively similar among species, despite morphological differences. Summer drought affected the water status of all species more negatively than winter drought. Isotopic analysis of stem water revealed that all three species took up deeper soil water under drought conditions and shallow soil water after a large rainfall event in summer. Thus all three species appeared to use the same water sources most of the time. However, after a particularly dry summer, only the deepest-rooted species continued to take up soil water, while the more shallow-rooted species were either dead or dormant. Our study suggests therefore that see front matter r 2004 Elsevier Ltd. All rights reserved. jaridenv.2004. 07.003 nding author.

Assessment of Soil Structure Under Monoculture of Vines

Assessment of Soil Structure Under Monoculture of Vines Long-term impact of vine growing on the soil structure stability was studied in three wine-growing areas of Slovakia. In Leptosols, the highest content of water-stable aggregates was determined. This soil type had the lowest vulnerability of soil structure as well. In Chernozems, the highest stability of soil structure was determined, while on the other hand, in Fluvisols, soil structure had the highest vulnerability. Between rows of vines in comparison to rows of vines a more favourable soil structure was determined. In vineyards, the soil structure state depends on the quantity and stability of soil organic matter, as well as particle size distribution.
Targeted Remedial Education for Underperforming Teenagers: Costs and Benefits

This study evaluates the short‐term effects of a remedial education program that provided additional instruction to underperforming high school students in Israel. The intervention prepared students for the matriculation exams. Using a comparison group of schools that enrolled in the program later and implementing a difference‐in‐differences estimation strategy, we found that the program raised the school mean matriculation rate by 3.3 percentage points. This gain reflects an effect on targeted participants and the absence of externalities on their untreated peers. The program was found to be less cost effective than two alternative interventions based on incentives for teachers and students.
Intentionality, Information, and Experience

The fact that we have thoughts about things is a salient feature of our mental life. In phenomenology this feature goes by the name intentionality, while cognitive psychologists prefer to speak of the representational power of the mind. Where does this power come from? It is generally agreed today that one attempt at answering this question has thoroughly failed. The power of mental representation (i.e. intentionality) cannot be explained as a feature of language. Many philosophers have therefore turned to a more promising project, namely to explain intentionality in information-theoretic terms. This project, too, has come under attack however. Such reductive explanations fail, it is argued, because they leave out the constitutive relation between intentionality and experience. If intentionality can be explained at all, it must be grounded in a primitive non-relational feature of our experience. In this paper I will take up this adverbialist challenge to an information-theoretic explanation of intentionality and show how it can be met.
X-ray lines from dark matter: the good, the bad, and the unlikely

We consider three classes of dark matter (DM) models to account for the recently observed 3.5 keV line: metastable excited state DM, annihilating DM, and decaying DM. We study two examples of metastable excited state DM. The first, millicharged composite DM, has both inelasticity and photon emission built in, but with a very constrained parameter space. In the second example, up-scattering and decay come from separate sectors and is thus less constrained. The decay of the excited state can potentially be detectable at direct detection experiments. However we find that CMB constraints are at the border of excluding this as an interpretation of the DAMA signal. The annihilating DM interpretation of the X-ray line is found to be in mild tension with CMB constraints. Lastly, a generalized version of decaying DM can account for the data with a lifetime exceeding the age of the Universe for masses ≲106 GeV.
Study on feature extraction method of Han Dynasty stone carving images

Han Dynasty stone carving is Chinese nation’s outstanding cultural heritage, how to protect and promote it is an historical responsibility. In recent years, there has been a lot of research on the Han Dynasty stone carving, and has achieved certain results. But the digital research on it is still very rare. This is mainly because the own characteristics of Han Dynasty stone carving images make feature extraction become difficult. Feature extraction is the key point of Han Dynasty stone carving’s digital research, which directly affects the accuracy of image retrieval and the efficiency of image matching algorithm. This paper based on the analysis of the characteristics of Han Dynasty stone carving images and the existing image feature extraction methods, puts forward a scheme for feature extraction of Han Dynasty stone carving images which adopts multifeature fusion.

The Cradle of Thought: Growth, Learning, Play and Attachment in Neanderthal Children

Childhood is a core stage in development, essential in the acquisition of social, practical and cultural skills. However, this area receives limited attention in archaeological debate, especially in early prehistory. We here consider Neanderthal childhood, exploring the experience of Neanderthal children using biological, cultural and social evidence. We conclude that Neanderthal childhood experience was subtly different from that of their modern human counterparts, orientated around a greater focus on social relationships within their group. Neanderthal children, as reflected in the burial record, may have played a particularly significant role in their society, especially in the domain of symbolic expression. A consideration of childhood informs broader debates surrounding the subtle differences between Neanderthals and modern humans.
Adaptability and stability parameters for immature seeds and pods and mature dried seeds in cowpea genotypes in Brazil Northeast.

The aim of this study was to estimate adaptability and stability parameters in genotypes of cowpea for the yield of immature seeds and pods and mature dried seeds, in order to enable the recommendation of cultivars for the region of Sao Francisco Submedium valley. We evaluated 30 cowpea genotypes, being fourteen lines of Embrapa Semiarid, six commercial cultivars and 10 landraces in the municipalities of Juazeiro-BA and Petrolina-PE. The experiments were conducted in the second semester, during the years 2013, 2014 and 2015. For adaptability and stability analysis, the methodologies of Eberhart and Russell, Lin and Binns were used, in addition to the multiplicative method, based on principal components analysis (AMMI). A significant difference was observed for the mean squares of treatments in all environments, as well as the pooled ANOVA (P<0.01) for the effects of genotypes (G), environments (E) and G*E interaction. The lines P290, P303, P508 and PC950409D02E showed yield of immature seeds exceeding 2140 kg ha-1, broad stability and good predictability in the series of evaluated environments, and has great potential to be recommended as new cultivars for the region of Sao Francisco Submedium Valley.
On extensions of lax monads

In this paper we construct extensions of Set-monads – and, more generally, lax Rel-monads – into lax monads of the bicategory Mat(V) of generalized V-matrices, whenever V is a well-behaved lattice equipped with a tensor product. We add some guiding examples. Introduction Extensions of Set-monads into lax monads in bicategories of generalized matrices have been used recently to study categories of lax algebras [4, 9, 8], generalizing Barr’s [1] description of topological spaces as lax algebras for the ultrafilter monad and Lawvere’s [14] description of metric spaces as V-categories for V the real half-line. The recent interest in this area had its origin in the use of the description of topological spaces via ultrafilter convergence to characterize special classes of continuous maps, such as effective descent morphisms, triquotient maps, exponentiable maps, quotient maps and local homeomorphisms [16, 13, 3, 6, 12, 5]. In this area, one of the difficulties one has to deal with is the construction of lax extensions of Set-monads into a larger bicategory. Contrarily to the extensions studied so far, with ad-hoc constructions, here we present a uniform construction of an extension of a Set-monad, satisfying (BC), into a lax monad of the bicategory Mat(V) of generalized V-matrices. This construction consists of three steps: first we apply Barr’s extension of the monad into the category Rel of relations (in Section 1) and then we extend this into Mat(2 op ) and finally into Mat(V) (as described in Section 3). This construction includes, for instance, Clementino-Tholen construction of an extension of the ultrafilter monad in case V is a lattice (Example 5.4). The techniques used here can be used also to extend lax monads from Rel into Mat(V). We find particularly interesting the presentation of the Hausdorff metric on subsets of a metric space as an extension of the lax powerset monad (Example 6.3). 2000 Mathematics Subject Classification. 18D05, 18C20, 18D10.
Dietary Protein Requirements of Juvenile Barbless Carp, Cyprinus pellegrini

The dietary protein requirements of juvenile barbless carp, Cyprinus pellegrini, were determined. Five isoenergetic diets containing graded levels of protein (29%, 34%, 39%, 44%, 49%) were fed to triplicate groups of fish (12.4 g) for 10 weeks in a recirculating rearing system maintained at 18-22°C. Weight gain significantly increased as the dietary protein level increased to 44%, then slightly declined. Specific growth rate (SGR) significantly increased as the dietary protein level increased to 39%, then reached a plateau. In contrast, the feed conversion ratio decreased as the dietary protein level increased to 39%. The highest feed intake and protein efficiency ratio were obtained in fish fed the 34% diet. Broken-line regression analysis shows that the optimum dietary protein level for the maximum SGR is 39.3±1.7%, while second-order polynomial regression analysis shows that the maximum SGR occurs at 43.6% and that the minimum protein requirement is 34.7-37.3%. Together, these results indicate that the optimum range of protein for juvenile C. pellegrini is 37.3-43.6%.
Research on Loop Detection of Power Grid Equipment Based on Graph Database

this paper presents a method of power grid loop detection based on graph database. The topology concept is introduced to extract the network relationship from the power grid equipment. The devices and power lines in the power grid correspond to the vertices in the topological graph, and the connection relation between the grid devices corresponds to the edges in the topological graph. The topological graph data model is generated by establishing the edges of connected vertices and stored in graph database. The loop detection of power grid equipment is divided into ordinary topological loop detection and multi-power loop detection, using the degree reduce algorithm and union-find sets to achieve the ordinary loop detection, and using the breadth first search algorithm to achieve the multipower loop detection. For large-scale power grid, the efficiency of power grid loop detection based on graph database can be 10 times higher than relational database.

Bartonella Neuroretinitis: A Case Report with New Insights from Fundus Autofluorescence Imaging

Purpose: Fundus autofluorescence (FAF) is a modern functional imaging modality utilized to characterize abnormalities of the retinal pigment epithelium (RPE). There are no prior studies demonstrating FAF findings in both symptomatic and asymptomatic eyes of patients diagnosed with Bartonella neuroretinitis. Methods: Case report and review of the literature. Patients: Single patient case study. Results: In the symptomatic right eye, (FAF-Heidelberg Retina Angiograph; Heidelberg Engineering, Heidelberg, Germany) identified abnormality of the RPE which corresponded to pathology seen on fundus photography, fluorescein angiography (FA-Heidelberg Retina Angiograph; Heidelberg Engineering, Heidelberg, Germany) and spectral domain optical coherence tomography (SD-OCT-Spectralis®, Heidelberg Engineering, Heidelberg, Germany). Interestingly, FAF also demonstrated sub-clinical anatomic abnormalities not seen clinically nor detected as clearly by any other imaging modalities in the patient’s asymptomatic left eye. As the patient improved clinically, normalization of the FAF occurred in both eyes. Discussion: This report is the first study to describe novel subclinical and clinical FAF findings as part of the evaluation of a patient with infectious neuroretinitis. Compared to FA, SD-OCT and clinical examination, FAF provided a more detailed functional understanding of this condition in its early stages and was also used to follow the clinical course of this patient. This functional imaging modality confirmed normalization of anatomic abnormalities also demonstrated by the other techniques.
Low-latitude climate variability in the Heinrich frequency band of the Late Cretaceous greenhouse world

Abstract. Deep marine successions of early Campanian age from DSDP (Deep Sea Drilling Project) site 516F drilled at low paleolatitudes in the South Atlantic reveal distinct sub-Milankovitch variability in addition to precession, obliquity and eccentricity-related variations. Elemental abundance ratios point to a similar climatic origin for these variations and exclude a quadripartite structure as an explanation for the inferred semi-precession cyclicity in the magnetic susceptibility (MS) signal as observed in the Mediterranean Neogene for precession-related cycles. However, semi-precession cycles as suggested by previous work are likely an artifact reflecting the first harmonic of the precession signal. The sub-Milankovitch variability, especially in MS, is best approximated by a ~7 kyr cycle as shown by spectral analysis and bandpass filtering. The presence of sub-Milankovitch cycles with a period similar to that of Heinrich events of the last glacial cycle is consistent with linking the latter to low-latitude climate change caused by a non-linear response to precession-induced variations in insolation between the tropics.
Effects of Salt and Drought Stresses on Germination and Seedling Growth of Pea (Pisum sativum L.)

The effects of salt and drought stresses at the water potentials of -2, -4, -6 and -8 bars induced by NaCl and PEG 6000 (polyethylene glycol 6000) each, on germination and early seedling growth, were investigated for 3 pea cultivars (Bolero, Sprinter and Utrillo). Electrical conductivity (EC) values of the NaCl solutions were 4.5, 8.8, 12.7 and 16.3 dS m-1. Germination percentage, mean germination time, root and shoot length, and seedling fresh and dry weight were measured in the study. The objective was to determine genotypic differences among pea cultivars in terms of salt and drought stress and to determine factors (salt toxicity or osmotic stress due to PEG) inhibiting seed germination. The germination results revealed that the genotypes significantly differed for salt and drought stress. Bolero appeared to be more tolerant to salt stress, but Sprinter cv. gave higher values under drought stress. Both NaCl and PEG inhibited germination and seedling growth in all cultivars, but the effects of NaCl compared to PEG were less on germination and seedling growth. All cultivars were able to germinate at all NaCl levels without a significant decrease in germination, while a drastic decrease in germination was recorded at -6 bars of PEG. It was concluded that inhibition in germination at equivalent water potentials of NaCl and PEG was mainly due to an osmotic effect rather than salt toxicity.
Social Cognition in Down Syndrome: Face Tuning in Face-Like Non-Face Images

Individuals with Down syndrome (DS) are widely believed to possess considerable socialization strengths. However, the findings on social cognition capabilities are controversial. In the present study, we investigated whether individuals with DS exhibit shortage in face tuning, one of the indispensable components of social cognition. For this purpose, we implemented a recently developed Face-n-Food paradigm with food-plate images composed of food ingredients such as fruits and vegetables. The key benefit of such face-like non-face images is that single elements do not facilitate face processing. In a spontaneous recognition task, 25 children with DS aged 9 to 18 years were presented with a set of Face-n-Food images bordering on the Giuseppe Arcimboldo style. The set of images was administered in a predetermined order from the least to most resembling a face. In DS individuals, thresholds for recognition of the Face-n-Food images as a face were drastically higher as compared not only with typically developing controls, but also with individuals with autistic spectrum disorders and Williams-Beuren syndrome. This outcome represents a significant step toward better conceptualization of the visual social world in DS and neurodevelopmental disorders in general.
