description: We investigate experimentally the mechanical response to shear of a 2D packing of grains across the jamming transition. First, we develop a dedicated experimental setup, together with tracking and photoelastic techniques in order to prepare the packing in a controlled fashion and to quantify the stress and strain tensors at the grain scale. Second, we install a inflating probe (a 2D "balloon"), which shears the packing with a cylindrical symmetry. We probe experimentally stresses and strains for strain amplitudes as low as $10^{-3}$ and for a range of packing fractions within $2\%$ variation around the jamming transition. We observe not only that shear strain induces shear stresses, but also normal stresses. Moreover, we show that both shear and normal stresses behave nonlinearly with the shear strain. Finally, we show by scaling analysis that the constitutive laws are controlled by the Jamming transition.

description: Les élevages intensifs d’animaux génèrent de très fortes quantités de bioaérosols, ces derniers proviennent des animaux eux-mêmes (squame, matières fécales, poils, plumes) de leur litière ou de la nourriture. Les niveaux d’exposition des travailleurs à ces différents bioaérosols (bactéries, champignons, endotoxines) sont bien documentés, cependant la composition et la dynamique de ces communautés de microorganismes et de leurs dérivés au cours des saisons est très peu étudiée. De même, la présence de bactéries résistantes aux antibiotiques dans l’air de ces élevages reste encore peu documentée. Les résultats de plusieurs études menées dans des élevages de porcs seront présentés.

description: Les particules de suie sont considérées comme des aérosols importants dans l'atmosphère en raison de leur rôle dans la formation du nuage en tant que potentiels noyaux de condensation (CCNs). Les suies fraîches sont généralement considérées comme hydrophobes. Néanmoins, les processus de vieillissement dans l'atmosphère peuvent modifier leur morphologie et composition chimique de surface, et les rendre hydrophiles. Les propriétées hygroscopiques des particules de suie sont généralement estimées par la mesure de la fraction activée Fa qui est donnée par le rapport du nombre des goutelettes formées sur le nombre de CCNs. En supposant que les CCNs sont monodispersés et de forme sphérique, la théorie de ?-Köhler est généralement utilisée pour obtenir un « paramètre d'hygroscopicité » ? qui exprime quantitativement les propriétés hygroscopiques de l'aérosol. Dans ce travail, un modèle pour obtenir ? est proposé en prenant en compte la distribution de taille et la morphologie des CCNs. Le modèle est testé avec des CCNs générés à partir de sulfate d'ammonium qui produit des particules quasi-sphériques et qui possèdent des distributions log-normale. Les résultats expérimentaux de l'hygroscopie des particules sèches de sulfate d'ammonium concordent très bien avec la simulation par le modèle. Ensuite, le modèle est utilisé pour obtenir ? des particules de suie vieillies en presence de radicaux OH. Les paramètres pris en compte sont le diamètre de mobilité Dm, la dimension fractale Df, le diamètre des particules primaires Dpp et l'écart type géométrique des volumes équivalents des particules de suie.

description: We want to understand the kinematic and thermal properties of young massive gas clumps prior to and at the earliest evolutionary stages of high-mass star formation. Do we find signatures of gravitational collapse? Do we find temperature gradients in the vicinity or absence of infrared emission sources? Do we find coherent velocity structures toward the center of the dense and cold gas clumps? To determine kinematics and gas temperatures, we used ammonia, because it is known to be a good tracer and thermometer of dense gas. We observed the NH$_3$(1,1) and (2,2) lines within seven very young high-mass star-forming regions with the VLA and the Effelsberg 100m telescope. This allows us to study velocity structures, linewidths, and gas temperatures at high spatial resolution of 3-5$"$, corresponding to $\sim$0.05 pc. We find on average cold gas clumps with temperatures in the range between 10 K and 30 K. The observations do not reveal a clear correlation between infrared emission peaks and ammonia temperature peaks. We report an upper limit for the linewidth of $\sim$1.3 km s$^{-1}$, at the spectral resolution limit of our VLA observation. This indicates a relatively low level of turbulence on the scale of the observations. Velocity gradients are present in almost all regions with typical velocity differences of 1 to 2 km s$^{-1}$ and gradients of 5 to 10 km s$^{-1}$ pc$^{-1}$. These velocity gradients are smooth in most cases, but there is one exceptional source (ISOSS23053), for which we find several velocity components with a steep velocity gradient toward the clump centers that is larger than 30 km s$^{-1}$ pc$^{-1}$. This steep velocity gradient is consistent with recent models of cloud collapse. Furthermore, we report a spatial correlation of ammonia and cold dust, but we also find decreasing ammonia emission close to infrared emission sources.

Les résultats obtenus à partir des différentes configurations ont été comparés afin de déterminer le taux de capture en fonction de la taille des confinements, de la taille des particules et de la masse de la charge explosive. Ils confirment l'efficacité de la mousse pour capturer les particules, et, spécifiquement, les plus grosses.

description: We show that in 1+1 dimensional conformal field theories, exciting a state with a local operator increases the Renyi entanglement entropies by a constant which is the same for every member of the conformal family. Hence, it is an intrinsic parameter that characterises local operators from the perspective of quantum entanglement. In rational conformal field theories this constant corresponds to the logarithm of the quantum dimension of the primary operator. We provide several detailed examples for the second Renyi entropies and a general derivation.

description: Certaines applications industrielles utilisent de la poudre de carbure de silicium sur des durées allant de plusieurs heures à plusieurs mois. De telles durées induisent des problématiques d'émission (exposition des opérateurs, rejets à l'environnement) mais aussi de modification de la poudre elle-même. Ces problématiques sont très peu considérées à ce-jour, les tests de pulvérulence étant principalement centrés sur les quantités de matière émises, et ce pour des durées plus courtes. Les résultats présentés ici portent sur l'étude par agitateur vortex [3, 4] de la pulvérulence en masse et en nombre de deux types de poudre de SiC de diamètre médian (x50) de 66 µm et 38 µm, sur des périodes de 6 heures. Le mécanisme de génération de poussières peut comprendre la libération d'aérosol due à l'attrition des particules due à l'impaction entre particules et à la paroi des particules. Cette étude souligne la nécessité de procéder à des essais à long terme sur la poussière pour les matériaux durs comme le SiC et à la caractérisation des propriétés des matériaux en vrac en raison de la génération et de la libération de poussières. En outre, les résultats peuvent être trouvés dans le matériau en vrac pour des applications à long terme basées sur la poussière.

description: The proportion of teens and young adults with driver's licenses has declined sharply in many industrialized countries including the United States. Explanations for this decline have ranged from the introduction of graduated driver licensing programs to the increase in online social interaction. We used a longitudinal cohort study of teenage girls in San Diego and Minneapolis to evaluate factors associated with licensure and whether teens' travel patterns become more independent as they aged. We found that licensure depended not only on age, but on race and ethnicity as well as variables that correlate with household income. Results also showed evidence that teen travel became more independent as teen's age, and that acquiring a license is an important part of this increased independence. However, we found limited evidence that teen's travel-activity patterns changed as a result of acquiring a driver's license. Rather, teen independence resulted in less parental chauffeuring, but little shift in travel patterns. For the larger debate on declining Millennial mobility, our results suggest the need for more nuanced attention to variation across demographic groups and consideration of the equity implications if declines in travel and licensure are concentrated in low-income and minority populations.

description: Nous présentons ici une synthèse des résultats, obtenus par l'équipe, sur la charge des aérosols submicroniques par collection d'ions gazeux, produits par plasma à pression atmosphérique. L'objectif est de montrer l'intérêt d'utiliser les plasmas pour identifier les leviers qui contrôlent le nombre de charges électriques par particule et ainsi développer des chargeurs optimisés selon l'application visée. Le plasma est produit, soit par une décharge couronne pour générer des ions d'une seule polarité (ions positifs ou négatifs), soit par une décharge à barrières diélectriques pour des mélanges d'ions positifs et négatifs. Nous avons donc conçu plusieurs chargeurs et mesurer les niveaux de charge et les pertes des aérosols selon (i) leurs propriétés (diamètre et concentration), (ii) les conditions plasmas qui définissent la polarité des ions et contrôlent les densités d'ions et le champ électrique traversés par les aérosols, et (iii) les conditions de mélange ions-aérosols. Les contraintes liées à l'application (diamètre des particules, pénétration requise, niveau de charge souhaités) définissent la stratégie de charge qui doit être utilisée: injection des aérosols dans la décharge ou en postdécharge, dans des densités d'ions unipolaires ou bipolaires. Selon la stratégie de charge, les paramètres clés qui déterminent la charge moyenne d'un aérosol monodispersé en sortie de chargeur sont présentés. Enfin, la relation chargediamètre est critique pour les applications mobilimétriques, telles que les mesures de taille d'aérosols par analyse différentielle de mobilités électriques. Les relations charge-diamètre mesurées dans différentes conditions de mélange ions-aérosols démontrent qu'il est possible de contrôler cette relation et ainsi étendre le champ d'application de ces analyses mobilimétriques.

L'échantillonneur développé est extrêmement utile pour les plates-formes UAV (Unmanned Aircraft Vehicle) embarquées où la limitation du poids de la charge utile est un problème majeur. L'instrument dispose de deux unités 1) Unité de contrôle 2) Unité d'échantillonnage. L'unité de commande sert à commander à distance l'échantillonneur équipé d'un échantillonneur à faible débit. Les communications n / b des unités sont effectuées en utilisant un émetteur et un récepteur à 433 MHz. Les poids de l'unité de contrôle et de l'échantillonneur sont de 64 et 200 g, piles comprises. Le débit de l'échantillonneur a été maintenu à >1 ml / min. L'échantillonneur développé a été testé par rapport à son fonctionnement à distance et à son aptitude à des études de morphologie et d'états de mélange. L'opération à distance facilite la collecte de particules à un moment et à un endroit donnés (horizontal et vertical). Les particules recueillies à différentes échelles de temps ont été analysées à l'aide de SEM équipées d'EDS. EDS a été utilisé pour explorer la composition chimique élémentaire qui a montré que même les particules molles avaient une morphologie non perturbée. Pour une longue période de fonctionnement (~ 8 heures), les particules collectées sur le filtre en PTFE peuvent également fournir des informations sur la concentration gravimétrique en masse (?g / m3). L'échantillonneur TSPM a été développé avec des capacités de fonctionnement à distance. Il fonctionne avec des piles légères et à faible débit (fonctionne avec des piles rechargeables à courant continu). Les micrographies de particules individuelles révèlent des morphologies non perturbées.

description: Remote Work bietet unterschiedliche Chancen und Herausforderungen für Organisationen und Arbeitnehmende. Mit dieser Studie wurde mittels Interviews von HR-Verantwortlichen zu erfassen versucht, wie die zukünftige Entwicklung von Remote Work aussehen könnte und welche neuen Standardarbeitsmodelle sich in der Schweiz etablieren könnten. Dabei wurden insbesondere die organisatorischen Bedingungen sowie die zielführenden Kompetenzen für Führungskräfte und Mitarbeitende beleuchtet und gefragt, ob ein Swiss Remote Work Competence Center für Dienstleistungen rund um das Thema Remote Work aus Sicht der Arbeitgebenden als hilfreich angesehen wird.
 Aus den Ergebnissen wird ersichtlich, dass ungleich den theoretischen Ausführungen die asynchrone und ortsunabhängige Verrichtung von Arbeit nicht durchgehend als Chance gewertet wird und insbesondere die unternehmenskulturellen Facetten und der Wandel im Autonomiegrad und der Führungshaltung eine Herausforderung darstellen.
 Ein Swiss Remote Work Competence Center würde speziell für den Austausch und Best Practices zu Hybrid- und Remote Work-Themen mit anderen Organisationen geschätzt und sollte aus Sicht der HR-Verantwortlichen Informationen und Workshops zu digitaler Kooperation, zu Führungsfragen und Führungsausbildungen bieten. Die Klärung von arbeitsrechtlichen Fragen und Sozialversicherungen, Informationen zum Arbeiten im Ausland, Inputs zu neuen Arbeitsformen sowie Arbeitsplatzinfrastrukturen und Zugang zu wissenschaftlichen Erkenntnissen könnten das Angebot ergänzen.

description: Prenatal maternal mood may explain the adverse obstetric outcomes seen in disadvantaged populations yet the effects of trauma history are not well studied. We examined the impact of trauma exposure and mood symptoms on obstetric outcomes in 358 women. Women with antecedent trauma were more likely to have a history of depression χ2(1, N = 358) = 19.2, p =.001; OR = 2.83, 95% CI [1.81, 4.42], were younger at their first pregnancy t(356) = −2.97, p = .003 and had a higher number of previous pregnancies t(356) = 2.77, p = .011 compared to those with no trauma exposure. Women with prenatal anxiety had significantly smaller babies than nonanxious women F(1, 322) = 5.32, p = .024. Trauma history magnified the effects of maternal prenatal mood on birth weight; the moderating effect was limited to those who first experienced a trauma under 18 years of age F(14, 320) = 2.44, p =.005. Childhood trauma exposure increases vulnerability for low birthweight delivery associated with prenatal mood disturbance. Screening pregnant women for trauma history and current mood symptoms is indicated.

description: OBJECTIVE: To study clinical manifestations and outcome of hyponatremia and hypernatremia in children with diarrhea.

METHOD: We compared children aged 0-59 months hospitalized from 1 January to 31 December 2013 with hyponatremia (serum sodium <130 mmol/l), hypernatremia (serum sodium >150 mmol/l) and normonatremia (serum sodium 135-145 mmol/l).

RESULTS: The case fatality was significantly higher among the children with hypernatremia and hyponatremia than normonatremia. A logistic regression analysis adjusting for potential confounders revealed that children with hyponatremia are more likely to have convulsions, have severe acute malnutrition and be of older age compared with children with normal serum sodium. Children with hypernatremia are more likely to have convulsions and dehydration than normonatremic children (for all p < 0.05).

CONCLUSION: Early diagnosis and prompt management of hypo- and hypernatremia by identifying simple clinical predicting factors of these two conditions in diarrheal children <5 years of age is critically important to prevent deaths in such children, especially in resource-limited settings.

description: We study the geometry of metrics and convexity structures on the space of phylogenetic trees, which is here realized as the tropical linear space of all \ ultrametrics. The ${\rm CAT}(0)$-metric of Billera-Holmes-Vogtman arises from the theory of orthant spaces. While its geodesics can be computed by the Owen-Provan algorithm, geodesic triangles are complicated. We show that the dimension of such a triangle can be arbitrarily high. Tropical convexity and the tropical metric behave better. They exhibit properties desirable for geometric statistics, such as geodesics of small depth.

description: Introduction:  `Maharashtra is a 15th rank India in agricultural output. In 2019, agriculture and allied sectors like forestry, logging and fishing represented 13.12% of the GDP. Maharashtra took 3rd rank in population as a compare to other states. At the time of independence, more than one-half of the national income was contributed by agricultural. At the same time, more than 70% of total population was depended on agriculture. The agriculture secures faces the lot of challenges due to uncertainties in agriculture i.e. natural and artificial hazards especially Maharashtra state. Still, more people in India make money for their livelihood from this sector, than from all other economic sectors. In rural India, households that depend upon income from agriculture (either self-employed or as agricultural workforce) accounted from nearly 70% of the population. According to the World Bank collection of development indicator, employment in agriculture in India was reported 41. 49 percent in 2020. All this facts & figures show that, the need for the development of agricultural sector in India. Maharashtra has reached the stage of self-sufficiency but it is still cursed by nature. This poses a great risk to state farmers in agricultural production and on their way. It has been observed that fluctuations in crop production in the Indian also in Maharashtra subcontinent are mainly due to natural uncertainties such as droughts, floods, cyclones, storms, landslides, earthquakes etc. The government of India was introduced crop Insurance scheme to face these challenges. Pradhan Mantri Fasal Bima Yojana (PMFBY) is the one of the largest crop insurance scheme, which was introduced in Feb. 2016. In this study, main focused on performance of PMFBY in Maharashtra state from last five years.

description: Social media are increasingly reflecting and influencing behavior of other complex systems. In this paper we investigate the relations between a well-know micro-blogging platform Twitter and financial markets. In particular, we consider, in a period of 15 months, the Twitter volume and sentiment about the 30 stock companies that form the Dow Jones Industrial Average (DJIA) index. We find a relatively low Pearson correlation and Granger causality between the corresponding time series over the entire time period. However, we find a significant dependence between the Twitter sentiment and abnormal returns during the peaks of Twitter volume. This is valid not only for the expected Twitter volume peaks (e.g., quarterly announcements), but also for peaks corresponding to less obvious events. We formalize the procedure by adapting the well-known "event study" from economics and finance to the analysis of Twitter data. The procedure allows to automatically identify events as Twitter volume peaks, to compute the prevailing sentiment (positive or negative) expressed in tweets at these peaks, and finally to apply the "event study" methodology to relate them to stock returns. We show that sentiment polarity of Twitter peaks implies the direction of cumulative abnormal returns. The amount of cumulative abnormal returns is relatively low (about 1-2%), but the dependence is statistically significant for several days after the events.

description: Between 20 and 40 % of female sex workers (FSWs) began sex work before age 18. Little is known concerning whether early initiation of sex work impacts later experiences in adulthood, including violence victimization. This paper examines the relationship between early initiation of sex work and violence victimization during adulthood. The sample included 816 FSWs in Mombasa, Kenya, recruited from HIV prevention drop-in centers who were 18 years or older and moderate-risk drinkers. Early initiation was defined as beginning sex work at 17 or younger. Logistic regression modeled recent violence as a function of early initiation, adjusting for drop-in center, age, education, HIV status, supporting others, and childhood abuse. Twenty percent of the sample reported early initiation of sex work. Although both early initiators and other FSWs reported commonly experiencing recent violence, early initiators were significantly more likely to experience recent physical and sexual violence and verbal abuse from paying partners. Early initiation was not associated with physical or sexual violence from non-paying partners. Many FSWs begin sex work before age 18. Effective interventions focused on preventing this are needed. In addition, interventions are needed to prevent violence against all FSWs, in particular, those who initiated sex work during childhood or adolescence.
Photon trapping in cavity quantum electrodynamics

Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We propose and analyze a scheme for photon trapping in an optical resonator coupled with two-level atoms. We show that when the cavity is excited by two identical light fields from two ends of the cavity respectively, the output light from the cavity is suppressed while the intra-cavity light field is near the maximum due to the excitation of the polariton state of the coupled cavity and atom system. We also present methods for the direct probing of the trapped polariton state. The photon trapping is manifested by the destructive interference of the transmitted light and the incident light. Such photon trapping is quite generic and should be observable experimentally in a variety of cavity quantum electrodynamics systems.

description: Aims. We study the coherency of solar spicules intensity oscillations with increasing height above the solar limb in quiet Sun, active Sun and active region using observations from HINODE/SOT. Existence of coherency up to transition region strengthens the theory of the coronal heating and solar wind through energy transport and photospheric oscillations. Methods. Using time sequences from the HINODE/SOT in Ca II H line, we investigate oscillations found in intensity profiles at different heights above the solar limb. We use the Fourier and wavelet analysis to measure dominant frequency peaks of intensity at the heights, and phase difference between oscillations at two certain heights, to find evidence for the coherency of the oscillations. Finally, we can calculate the energy and the mass transported by spicules providing energy equilibrium, according to density values of spicules at different heights. To extend this work, we can also consider coherent oscillations at different latitudes and suggest to study of oscillations which may be obtained from observations of other satellites.
