description: The so-called rain-cracking of sweet cherry fruit severely threatens commercial production. Simple observation tells us that cuticular microcracking (invisible) always precedes skin macrocracking (visible). The objective here was to investigate how a macrocrack develops. Incubating detached sweet cherry fruit in deionized water induces microcracking. Incubating fruit in D2O and concurrent magnetic resonance imaging demonstrates that water penetration occurs only (principally) through the microcracks, with nondetectable amounts penetrating the intact cuticle. Optical coherence tomography of detached, whole fruit incubated in deionized water, allowed generation of virtual cross-sections through the zone of a developing macrocrack. Outer mesocarp cell volume increased before macrocracks developed but increased at a markedly higher rate thereafter. Little change in mesocarp cell volume occurred in a control zone distant from the crack. As water incubation continued, the cell volume in the crack zone decreased, indicating leaking/bursting of individual mesocarp cells. As incubation continued still longer, the crack propagated between cells both to form a long, deep macrocrack. Outer mesocarp cell turgor did not differ significantly before and after incubation between fruit with or without macrocracks; nor between cells within the crack zone and those in a control zone distant from the macrocrack. The cumulative frequency distribution of the log-transformed turgor pressure of a population of outer mesocarp cells reveals all cell turgor data followed a normal distribution. The results demonstrate that microcracks develop into macrocracks following the volume increase of a few outer mesocarp cells and is soon accompanied by cell bursting.

description: We study the evolution of a single-electron packet of Lorentzian shape along an edge of the integer quantum Hall regime or in a Mach-Zehnder interferometer, considering a capacitive Coulomb interaction and using a bosonization approach. When the packet propagates along a chiral quantum Hall edge, we find that its electron density profile becomes more distorted from Lorentzian due to the generation of electron-hole excitations, as the interaction strength increases yet stays in a weak interaction regime. However, as the interaction strength becomes larger and enters a strong interaction regime, the distortion becomes weaker and eventually the Lorentzian packet shape is recovered. The recovery of the packet shape leads to an interesting feature of the interference visibility of the symmetric Mach-Zehnder interferometer whose two arms have the same interaction strength. As the interaction strength increases, the visibility decreases from the maximum value in the weak interaction regime, and then increases to the maximum value in the strong interaction regime. We argue that this counterintuitive result also occurs under other types of interactions.

description: One of the most common images of the Tunisian revolution is the photograph of President Ben Ali in the hospital next to Mohamed Bouazizi’s bed on 28th December 2010. It evokes the strength of a man about to die whose death will upset the country. The dramatic gesture of Mohamed Bouazizi helped the Tunisian society to regain public space. Reclaiming the voice is crucial for the Tunisian revolutionary dynamic. The cry of Bouazizi seems to be heard. That is why we can put into perspective the death of Mohamed Bouazizi with the immolation of Ryszard Siwiec in 1968 who had protested against the Soviet intervention in Czechoslovakia. Hear my cry is the title of the documentary that chronicles the last days of Ryszard Siwiec. The comparative study devoted to these heroes allows us to see the importance of the body and of her sacrifice in resistance to authoritarian systems.

description: Démarche. L’absence de locaux appropriés, de pièces dédiées et de lave-bassins au centre hospitalier isarien de Clermont de l’Oise, ainsi que la spécificité de la prise en charge des patients en psychiatrie, nous a conduits à mettre en place des solutions alternatives pour éviter la diffusion des infections liées aux excreta dans notre établissement. Nous avons ensuite élargi notre démarche à la prise en charge globale du patient selon cinq axes de travail : (1) le repérage des patients porteurs de bactéries hautement résistantes émergentes à l’admission ; (2) les soins de nursing ; (3) la prévention de la constipation due aux traitements psychotropes ; (4) la gestion des excreta proprement dite ; (5) l’hygiène des mains. Résultats. Ce programme a permis de sensibiliser les soignants à l’application des précautions standard, qui intègrent depuis juillet 2017 la gestion des excreta. Une prise de conscience de l’importance de l’hygiène des mains pour prévenir la transmission manuportée a émergé au niveau de leurs pratiques. Toutefois, les résultats précis de ces actions préventives sont difficiles à évaluer, du fait de la rareté du portage infectieux et des épidémies en psychiatrie.

description: Dark matter (DM) self-interactions have important implications for the formation and evolution of structure, from dwarf galaxies to clusters of galaxies. We study the dynamics of self-interacting DM via a light mediator, focusing on the quantum resonant regime where the scattering cross section has a non-trivial velocity dependence. While there are long-standing indications that observations of small scale structure in the Universe are not in accord with the predictions of collisionless DM, theoretical study and simulations of DM self-interactions have focused on parameter regimes with simple analytic solutions for the scattering cross section, with constant or classical velocity (and no angular) dependence. We devise a method that allows us to explore the velocity and angular dependence of self-scattering more broadly, in the strongly-coupled resonant and classical regimes where many partial modes are necessary for the achieving the result. We map out the entire parameter space of DM self-interactions --- and implications for structure observations --- as a function of the coupling and the DM and mediator masses. We derive a new analytic formula for describing resonant s-wave scattering. Finally, we show that DM self-interactions can be correlated with observations of Sommerfeld enhancements in DM annihilation through indirect detection experiments.

description: Bystander programs contribute to crime prevention by motivating people to intervene in violent situations. Social media allow addressing very specific target groups, and provide valuable information for program evaluation. This paper provides a conceptual framework for conducting benefit–cost analysis of bystander programs and puts a particular focus on the use of social media for program dissemination and data collection. The benefit–cost model treats publicly funded programs as investment projects and calculates the benefit–cost ratio. Program benefit arises from the damages avoided by preventing violent crime. We provide systematic instructions for estimating this benefit. The explained estimation techniques draw on social media data, machine-learning technology, randomized controlled trials and discrete choice experiments. In addition, we introduce a complementary approach with benefits calculated from the public attention generated by the program. To estimate the value of public attention, the approach uses the bid landscaping method, which originates from display advertising. The presented approaches offer the tools to implement a benefit–costs analysis in practice. The growing importance of social media for the dissemination of policy programs requires new evaluation methods. By providing two such methods, this paper contributes to evidence-based decision-making in a growing policy area.

description: This study investigated the exercise-induced changes in oxidative stress, nitric oxide (NO) metabolism and amino acid profile in plasma of omnivorous (OMN, n = 25), lacto-ovo-vegetarian (LOV, n = 25) and vegan (VEG, n = 23) recreational runners. Oxidative stress was measured as malondialdehyde (MDA), NO as nitrite and nitrate, and various amino acids, including homoarginine and guanidinoacetate, the precursor of creatine. All analytes were measured by validated stable-isotope dilution gas chromatographic-mass spectrometric methods. Pre-exercise, VEG had the highest MDA and nitrate concentrations, whereas nitrite concentration was highest in LOV. Amino acid profiles differed between the groups, with guanidinoacetate being highest in OMN. Upon acute exercise, MDA increased in the LOV and VEG group, whereas nitrate, nitrite and creatinine did not change. Amino acid profiles changed post-exercise in all groups, with the greatest changes being observed for alanine (+28% in OMN, +21% in LOV and +28% in VEG). Pre-exercise, OMN, LOV and VEG recreational runners differ with respect to oxidative stress, NO metabolism and amino acid profiles, in part due to their different dietary pattern. Exercise elicited different changes in oxidative stress with no changes in NO metabolism and closely comparable elevations in alanine. Guanidinoacetate seems to be differently utilized in OMN, LOV and VEG, pre- and post-exercise.

description: We compare two approaches to non-Markovian quantum evolution: one based on the concept of divisible maps and the other one based on distinguishability of quantum states. The former concept is fully characterized in terms of local generator whereas it is in general not true for the latter one. A simple example of random unitary dynamics of a qubit shows the intricate difference between those approaches. Moreover, in this case both approaches are fully characterized in terms of local decoherence rates. As a byproduct it is shown that entropy might monotonically increase even for non-Markovian qubit dynamics.

description: We present ab initio studies of structures, energetics, and diffusion properties of Mg in Si, Ge, and Sn diamond structures to evaluate their potential as insertion type anode materials for Mg batteries. We show that Si could provide the highest specific capacities (3817 mAh g-1) and the lowest average insertion voltage (~0.15 eV vs. Mg) for Mg storage. Nevertheless, due to its significant percent lattice expansion (~216%) and slow Mg diffusion, Sn and Ge are more attractive; both anodes have lower lattice expansions (~120 % and ~178 %, respectively) and diffusion barriers (~0.50 and ~0.70 eV, respectively for single-Mg diffusion) than Si. We show that Mg-Mg interactions at different stages of charging can decrease significantly the diffusion barrier compared to the single atom diffusion, by up to 0.55 eV.

description: We outline a strategy for showing convergence of loop-erased random walk on the Z^2 square lattice to SLE(2), in the supremum norm topology that takes the time parametrization of the curves into account. The discrete curves are parametrized so that the walker moves at a constant speed determined by the lattice spacing, and the SLE(2) curve has the recently introduced natural time parametrization. Our strategy can be seen as an extension of the one used by Lawler, Schramm, and Werner to prove convergence modulo time parametrization. The crucial extra step is showing that the expected occupation measure of the discrete curve, properly renormalized by the chosen time parametrization, converges to the occupation density of the SLE(2) curve, the so-called SLE Green's function. Although we do not prove this convergence, we rigorously establish some partial results in this direction including a new loop-erased random walk estimate.

description: A new device structure for spin transfer torque based magnetic random access memory is proposed for on-chip memory applications. Our device structure exploits spin Hall effect to create a differential memory cell that exhibits fast and energy-efficient write operation. Moreover, due to inherently differential device structure, fast and reliable read operation can be performed. Our simulation study shows 10X improvement in write energy over the standard 1T1R STT-MRAM memory cell, and 1.6X faster read operation compared to single-ended sensing (as in standard 1T1R STT-MRAMs). The bit-cell characteristics are promising for high performance on-chip memory applications.

Year: 2018

description: Contexte et objectif. Les infections associées aux soins touchent 1 patient sur 20 en France. Face à ces enjeux de santé publique, des stratégies vaccinales émergent. Cependant, en France, l’hésitation vaccinale s’avère croissante. Cette enquête cherche à évaluer l’acceptation de vaccins en cours de développement, tels que les vaccins anti-Staphylococcus aureus et anti-Clostridium difficile. Méthode. Cette étude qualitative par entretiens semi-dirigés a été menée auprès de 14 patients hospitalisés en vue de la pose d’une prothèse, entre octobre 2016 et juin 2017. Résultats. Même si le risque d’infection nosocomiale n’est pas la principale préoccupation des patients, S. aureus génère une grande crainte. Les patients ne se sentent pas concernés par les mesures de prévention. La proposition vaccinale est bien accueillie, mais le passage à l’acte vaccinal pourrait se heurter à de nombreuses réticences. La nouveauté du vaccin augmente la propension des patients à hésiter. Conclusion. Les polémiques vaccinales impactent les décisions des patients, qui souhaitent décider seuls des vaccins nécessaires à leur santé. L’hésitation des patients repose sur une méconnaissance du risque nosocomial et des processus vaccinaux. Il semble donc indispensable de prendre en charge leur information, pour permettre l’acceptation de ces vaccins qui pourraient venir.

description:   Objectif. L’objectif de cette étude était d’identifier les réservoirs environnementaux de persistance des bactéries productrices de carbapénémases (BPC) dans l’environnement proche du patient. Méthodes. Les surfaces de la chambre de patients porteurs ou infectés par des BPC ont été prélevées par écouvillonnage, 24 heures après l’entretien de la chambre. Après enrichissement puis isolement sélectif, chaque souche a été identifiée avec un instrument de type Matrix Assisted Laser Desorption Ionisation - Time of Flight (Maldi-Tof). Les pratiques d’hygiène ont été auditées et améliorées si besoin dans les 19 services accueillant ces patients. Résultats. 2 677 prélèvements ont été réalisés dans les chambres de 32 patients. Au total 238 souches ont été isolées dans les chambres des patients, et se répartissaient en : Klebsiella pneumoniae (n=100), Enterobacter cloacae (n=57), Escherichia coli (n=22) et Acinetobacter baumannii (n=59). Le taux de contamination des chambres variait de 0 % à 31,1 %. Il n’était lié ni aux espèces de BPC, ni au statut porteur ou infecté des patients, ni au type de service. Les catégories de surfaces présentant les plus forts taux de contamination étaient le mobilier (30 %) et les points d’eau (26 %). Conclusion. Ces résultats révèlent des surfaces à risque, formant des réservoirs privilégiés de transmission de bactéries responsables d’infections associées aux soins. Ces surfaces sont donc à cibler en priorité lors de l’entretien d’une chambre et lors des contrôles microbiologiques dans celle-ci, par exemple lors d’épidémies.

description: Candida auris (CA) est une levure pathogène opportuniste, capable de résister dans l’environnement et d’être multirésistante aux antifongiques. Des épidémies ont été décrites dans des hôpitaux d’Inde et de Grande-Bretagne. Nous rapportons la prise en charge d’un premier patient colonisé en France métropolitaine, et hospitalisé préalablement en Inde. CA a été isolé de sa gorge, et il a été placé dès son arrivée dans notre établissement en « précautions complémentaires contact avec marche en avant » (PCC bactéries hautement résistantes émergentes [BHRe]). Nous nous sommes notamment appuyés sur les recommandations américaines et anglaises pour mettre en place les mesures suivantes : PCC BHRe et Clostridium difficile, avec un bionettoyage efficace sur les spores ; trois dépistages pour chaque patient contact ; suivi épidémiologique hebdomadaire des patients exposés ; prélèvements microbiologiques d’environnement ; pas de dépistage des professionnels. Le patient est décédé le 52e jour. La vigilance a été maintenue grâce à l’accompagnement réalisé jour et nuit par l’équipe opérationnelle d’hygiène (EOH), et via des prélèvements de dépistage chez les patients et dans l’environnement de soins. Ces mesures ont évité une épidémie. Suite à cette expérience, nous avons mis en place un dépistage systématique de CA chez tout patient nouvellement hospitalisé et provenant d’un pays dit à risque, avec une alerte automatisée vers l’EOH.

description: Objectifs. Pour la gestion des excreta, les services d’oncologie et de chirurgie de l’institut du cancer de Montpellier sont équipés de laveurs-désinfecteurs de bassins (LDB). Nous avons commencé un travail sur la gestion des excreta en 2014, qui a conduit à la mise en œuvre de nombreuses actions correctives. L’objectif de cette étude était d’évaluer leur mise en œuvre. Méthode. En janvier 2017, l’équipe opérationnelle d’hygiène hospitalière (EOH) a mené une enquête auprès des aides-soignants (AS) et des infirmiers (IDE) de l’établissement, pour connaître leurs pratiques de gestion des excreta. Résultats. Vingt-cinq AS et 9 IDE ont participé à l’étude : 85 % d’entre eux éliminaient les selles des bassins dans les w.-c. de la chambre du patient et 97 % y vidangeaient également les urines des bassins et des urinaux. Le lavage du bassin était réalisé au LDB par 26 % des enquêtés en cas de selles, au LDB après un nettoyage manuel par 12 %, manuellement avec un détergent désinfectant par 12 %, et manuellement à l’eau par 44 %. Le lavage manuel était réalisé avec la douche du patient par 83 % des enquêtés ; le nettoyage des urinaux n’était pas réalisé par 12 %. Discussion. Nous avons constitué un groupe de travail pluridisciplinaire, chargé d’envisager le changement aux plans architectural, matériel et organisationnel. Des essais de broyeurs et de LDB ont été programmés et des formations menées. La gestion des excreta nécessite une démarche participative et pluridisciplinaire, ainsi qu’un investissement total de l’EOH.

title: Понятие ambitio в трудах Цицерона

Publisher: name: Новгородский государственный университет имени Ярослава Мудрого (НовГУ)
Year: 2019

description: Статья посвящена анализу содержания понятия ambitio в трудах Цицерона. Указанное понятие употребляется Цицероном 52 раза, его производные прилагательное ambitiosus — 15 раз и наречие ambitiose — 5 раз. Понятие может быть переведено как «честолюбие», «тщеславие», «искание должностей». Делается вывод о том, что отношение Цицерона к понятию ambitio неоднозначно. Если он говорит о друзьях или о себе, то чаще всего использует данное понятие в положительном смысле, в значении честолюбия, которым должен обладать политически активный гражданин Римской республики. В других случаях ambitio подразумевает тщеславие, которому сопутствует жажда власти и, в случае получения магистратуры, несправедливое правление. Понятие ambitio сочетается в сочинениях Цицерона как с пороками и деструктивными явлениями римской действительности (зависть, вражда, соперничество и др.), так и с положительными социально-политическими понятиями и явлениями (почет, достоинство, долг, слава, дружба).

description: The type-I intermittency route to (or out of) chaos is investigated within the Horizontal Visibility graph theory. For that purpose, we address the trajectories generated by unimodal maps close to an inverse tangent bifurcation and construct, according to the Horizontal Visibility algorithm, their associated graphs. We show how the alternation of laminar episodes and chaotic bursts has a fingerprint in the resulting graph structure. Accordingly, we derive a phenomenological theory that predicts quantitative values of several network parameters. In particular, we predict that the characteristic power law scaling of the mean length of laminar trend sizes is fully inherited in the variance of the graph degree distribution, in good agreement with the numerics. We also report numerical evidence on how the characteristic power-law scaling of the Lyapunov exponent as a function of the distance to the tangent bifurcation is inherited in the graph by an analogous scaling of the block entropy over the degree distribution. Furthermore, we are able to recast the full set of HV graphs generated by intermittent dynamics into a renormalization group framework, where the fixed points of its graph-theoretical RG flow account for the different types of dynamics. We also establish that the nontrivial fixed point of this flow coincides with the tangency condition and that the corresponding invariant graph exhibit extremal entropic properties.

title: Религия в жизни современных британских африканцев

description: Рассмотрены особенности деятельности африканских церквей, а также основные аспекты межрелигиозных отношений. Следует констатировать, что для развития религиоведения вообще и, в частности, вопросов о религии в жизни современных британских африканцев в частности необходимо выработать некоторую единую методологию, которая могла бы стать универсальной для исследования социальных проявлений религии в рамках социальной философии, а также других социальных наук, таких, как социология, политология и т.д. Религия для африканцев, проживающих в Великобритании, служит цементирующим фактором, позволяющим сохранять традиционные ценности, поддерживать культуру взаимной поддержки и чувство принадлежности к своей общине. Актуальность темы обусловлена тем, что африканские сообщества Великобритании, составляющие к 2010-м гг. около 1,5% населения страны, относятся к одной из самых молодых и динамично развивающихся этнических групп. Мигранты из Африки представлены практически во всех сферах жизни британского общества – политике, экономике, бизнесе, культуре, спорте, науке, масс-медиа. Для поддержания своего мировоззрения и особого образа жизни африканцы опираются на собственные религиозные движения. В отличие от англиканской церкви, христианские организации выходцев из Африки не находятся в упадке, а сохраняют и накапливают общественный авторитет, выступая одним из неотъемлемых атрибутов современной жизни африканских сообществ. Религия для африканцев, проживающих в Великобритании, служит цементирующим фактором, позволяющим сохранять традиционные ценности, поддерживать культуру взаимной поддержки и чувство принадлежности к своей общине. Африканские церкви весьма активны не только в Великобритании, но и в других странах Западной Европы и США. Они занимаются благотворительностью, реализуют образовательные и медицинские программы, берут на себя значительную социальную нагрузку по работе с неблагополучными семьями. В заключении подведены итоги по исследуемой теме.

description: A general purpose fitting model for one-dimensional astrometric signals is developed, building on a maximum likelihood framework, and its performance is evaluated by simulation over a set of realistic image instances. The fit quality is analysed as a function of the number of terms used for signal expansion, and of astrometric error, rather than RMS discrepancy with respect to the input signal. The tuning of the function basis to the statistical characteristics of the signal ensemble is discussed. The fit sensitivity to a priori knowledge of the source spectra is addressed. Some implications of the current results on calibration and data reduction aspects are discussed, in particular with respect to Gaia.

description: A previous dielectric, near-infrared (NIR), and nuclear magnetic resonance study on the hydrogen-bonded liquid 2-ethyl-1-hexanol [C. Gainaru et al., Phys. Rev. Lett. 107, 118304 (2011)] revealed anomalous behavior in various static quantities near 250 K. To check whether corresponding observations can be made for other monohydroxy alcohols as well, these experimental methods were applied to such substances with 5, 6, 7, 8, and 10 carbon atoms in their molecular backbone. All studied liquids exhibit a change of behavior near 250 K which is tentatively ascribed to effects of hydrogen bond cooperativity. By analyzing the NIR band intensities, a linear cluster size is derived that agrees with estimates from dielectric spectroscopy. All studied alcohols, except 4-methyl-3-heptanol, display a dominant Debye-like peak. Furthermore, neat 2-ethyl-1-butanol exhibits a well resolved structural relaxation in its dielectric loss spectrum which so far has only been observed for diluted monohydroxy alcohols.

description: In photography, low depth of field (DOF) is an important technique to emphasize the object of interest (OOI) within an image. Thus, low DOF images are widely used in the application area of macro, portrait or sports photography. When viewing a low DOF image, the viewer implicitly concentrates on the regions that are sharper regions of the image and thus segments the image into regions of interest and non regions of interest which has a major impact on the perception of the image. Thus, a robust algorithm for the fully automatic detection of the OOI in low DOF images provides valuable information for subsequent image processing and image retrieval. In this paper we propose a robust and parameterless algorithm for the fully automatic segmentation of low DOF images. We compare our method with three similar methods and show the superior robustness even though our algorithm does not require any parameters to be set by hand. The experiments are conducted on a real world data set with high and low DOF images.
