Published: March 2020

Abstract
We present the physical parameters of 2335 late-type contact binary (CB) systems extracted from the Catalina Sky Survey (CSS). Our sample was selected from the CSS Data Release 1 by strictly limiting the prevailing temperature uncertainties and light-curve fitting residuals, allowing us to almost eliminate any possible contaminants. We developed an automatic Wilson–Devinney-type code to derive the relative properties of CBs based on their light-curve morphology. By adopting the distances derived from CB (orbital) period–luminosity relations (PLRs), combined with the well-defined mass–luminosity relation for the systems’ primary stars and assuming solar metallicity, we calculated the objects’ masses, radii, and luminosities. Our sample of fully eclipsing CBs contains 1530 W-, 710 A-, and 95 B-type CBs. A comparison with literature data and with the results from different surveys confirms the accuracy and coherence of our measurements. The period distributions of the various CB subtypes are different, hinting at a possible evolutionary sequence. W-type CBs are clearly located in a strip in the total mass versus mass-ratio plane, while A-type CBs may exhibit a slightly different dependence. There are no significant differences among the PLRs of A- and W-type CBs, but the PLR zero-points are affected by their mass ratios and fill-out factors. Determination of zero-point differences for different types of CBs may help us improve the accuracy of the resulting PLRs. We demonstrate that automated approaches to deriving CB properties could be a powerful tool for application to the much larger CB samples expected to result from future surveys.

Abstract
We continuously monitored the blazar S5 0716+714 in the optical g, r, and i bands from 2017 November 10 to 2019 June 6. The total number of observations is 201 nights including 26,973 data points. This is a very large quasi-simultaneous multicolor sample for the blazar. The average time spans and time resolutions are 3.4 hr and 2.9 minutes per night, respectively. During the period of observations, the target source in the r band brightens from 14.ͫ16 to 12.ͫ29 together with five prominent subflares, and then becomes fainter to 14.ͫ76, and again brightens to 12.ͫ94 with seven prominent subflares. For the long-term variations, we find a strong flatter-when-brighter (FWB) trend at a low-flux state and then a weak FWB trend at a higher-flux state. A weak FWB trend at a low-flux state and then a strong FWB trend at a higher-flux state are also reported. Most subflares show strong FWB trends, except for two flares with a weak FWB trend. The particle acceleration and cooling mechanisms together with the superposition of the different FWB slopes from the subflares likely explain the optical color behaviors. A scenario of bent jet is discussed.

Published: March 2020

Background Protease inhibitors (PI) have relatively low penetration into the genital tract, raising concerns about the potential for genital HIV RNA shedding in patients taking PI-based regimens, particularly PI monotherapy (PI-mono). Methods We measured HIV RNA and PI drug concentrations in samples of semen, cervicovaginal and rectal mucosa secretions, and plasma in patients after 48–96 weeks on PI-mono or standard triple therapy. Results A total of 85 participants were recruited. Of the 43 participants on PI-mono (70% on darunavir [DRV]/ ritonavir [r]), 3 had detectable virus in semen or vaginal secretions (all below quantification limit), and none in rectal mucosa or plasma. Among those taking triple therapy, five had detectable virus in semen or vaginal secretions (HIV RNA >50 copies/ml in one), none in rectal mucosa and one in plasma. The median (IQR) concentration of DRV and atazanavir in semen (659.7 [339–1,089] and 128.8 [63–368] ng/ml, respectively) and cervico-vaginal samples (2,768 [312–7,879] and 1,836 [359–3,314] ng/ml, respectively) exceeded their protein adjusted median inhibition concentration (MIC50). DRV concentration in rectal secretions showed higher variability compared with concentration in the other sites, with particularly high rectal secretion/blood ratios (median 8.4, IQR 2.6–68.7:1). Conclusions We found no substantive evidence of HIV shedding in patients taking PI-mono, suggesting that PIs provide adequate control of virus in the genital compartment and are unlikely to lead to ongoing sexual transmission.
Entre narration et narrativité : récits de rêves et travail du rêver
Authors: Joly Fabien 
Published: March 2020

L’irréductible écart entre « récits de rêves » et « travail du rêver », entre le rêve raconté et le rêve rêvé apparaît comme un laboratoire singulier pour repérer et comprendre les deux registres de la narrativité et de la narration : leurs écarts autant que leurs articulations au sein d’un processus permanent de symbolisation et de subjectivation, au creux duquel les logiques de l’Inconscient se jouent, se nouent et se dialectisent. Hors du processus du rêve, il est proposé d’exporter cette dialectique « entre narration et narrativité » dans d’autres secteurs de la vie psychique ou de la thérapeutique.
Espoirs et désillusions du développement minier en contexte post-conflit. Un exemple congolais
Authors: Joncheray Mathilde 
Published: March 2020

Suite à la décennie de guerres des années 1990, et sous l’injonction des institutions internationales, la République du Congo a réalisé un nouveau code minier. Le secteur a été ainsi profondément reconfiguré, de grands conglomérats internationaux remplaçant les petites sociétés d’extraction étrangères, suscitant l’espoir de retombées rapides pour le développement du pays. Alors que l’imposition de plus en plus fréquente de règles de contenu local pourraient laisser présager d’un possible développement des territoires, l’absence de reconstruction, le manque d’infrastructures et de formations professionnelles adaptées au secteur minier constituent autant de freins à l’activité minière au Congo, provocant autant de désillusions.

Entrepreneurship orientation and innovation linkage: the case of Moroccan firms
Authors: Majdouline Ilias , El Baz Jamal , Jebli Fedwa 
Published: March 2020

Plusieurs recherches ont examiné comment les entrepreneurs détectent et exploitent les opportunités (e.g. Baron, 2008; Ucbasaran et al. , 2010) et comment l’innovation influence leurs entreprises (e.g. Ireland et al. , 2003; Kuratko et Audretsch, 2009). Cependant, la recherche empirique s’est focalisée en grande partie sur le contexte des pays avancés ou émergents et peu de recherches ont ciblé les pays en développement. En particulier, la recherche sur l’innovation entrepreneuriale dans les pays africains est en émergence. En prenant le Maroc comme terrain d’étude, le but de cette recherche est d’analyser comment les entrepreneurs marocains déploient l’innovation dans leurs activités entrepreneuriales. Notre démarche empirique est basée sur une approche qualitative à travers des entretiens avec des entrepreneurs marocains afin de cerner la thématique de l’orientation entrepreneuriale et sa relation avec l’innovation. L’analyse des cas d’entrepreneurs met en évidence différentes attitudes et approches de l’innovation entrepreneuriale des entreprises au Maroc. Sur la base des résultats obtenus, nous présenterons une discussion de leurs implications ainsi qu’un modèle conceptuel proposé et nous discuterons également les limites issues de notre recherche.
ARTICLE RETIRÉ : Le goût de l’autre
Authors: Jourdan-Peyrony Jessica , Servant Benoît 
Published: March 2020

Les auteurs proposent une réflexion théorico-clinique sur la place de la relation duelle dans la psychopathologie et le soin des patients en souffrance narcissique-identitaire, à partir de leur expérience en hôpital de jour soins études. Alors que la relation duelle est souvent considérée avec suspicion, le cadre institutionnel devant permettre la tiercéisation censée faire défaut, la première semble être un temps nécessaire incontournable du processus thérapeutique, ce que l’on peut rapprocher des conceptualisations du transfert dans ses deux temps de sexualisation et désexualisation. Les auteurs repèrent ainsi trois temps nécessaires dans l’évolution de leurs jeunes patients : surinvestissement d’un des objets de l’environnement ou du cadre idéalisé, déception et attaque de cet objet, dégagement de ce lien négatif et introjection d’une partie du travail élaboratif de l’équipe soignante. Cette réflexion est illustrée de nombreuses vignettes cliniques de ces différents temps.
Du concrétisme à la métaphore. Sur quelques aspects théoriques et techniques de travail psychanalytique avec des descendants de survivants à l’Holocauste
Authors: Grubrich-Simitis Ilse 
Published: March 2020

Au début des années 1960 commença le travail analytique avec les descendants des survivants des camps de concentration. L’auteure attire ici l’attention sur une caractéristique du fonctionnement du moi de ces patients dont les parents avaient dû d’abord exister face à la menace permanente de la mort, puis dénier leurs expériences traumatiques. L’altération de la capacité de métaphorisation dans ces conditions extrêmes se retrouve aussi chez les descendants de survivants. Ils considèrent ce qu’ils ont à dire comme des choses concrètes, et non comme étant remémoré ou fantasmé. De ce fait, leur expression est factuelle. L’objectif thérapeutique est alors de surmonter le concrétisme et de restaurer la capacité métaphorique. Pour ce faire, l’analyste doit surmonter le pacte de silence instauré dans la famille, et établir avec son patient la réalité de ce qui s’est passé. La « phase d’acceptation commune de la réalité de l’Holocauste » apparaît comme une étape indispensable à la restauration de la capacité métaphorique de la pensée et du langage, étape qui engage profondément les deux protagonistes dans un véritable travail de deuil.

Published: March 2020

Purpose:
To investigate corneal biomechanical properties in patients with childhood obesity.

Methods:
The study included 47 patients with childhood obesity (study group) and 39 healthy patients (control group). Corneal hysteresis, corneal resistance factor, corneal compensated intraocular pressure (IOPcc), and Goldmann-correlated IOP (IOPg) were measured with the Ocular Response Analyzer (Reichert, Ophthalmic Instruments, Buffalo, NY) in each eye. Central corneal thickness (CCT), anterior chamber angle (ACA), anterior chamber volume (ACV), and anterior chamber depth (ACD) measurements were obtained by the Pentacam rotating Scheimpflug camera (Oculus Optikgeräte GmBh, Wetzlar, Germany).

Results:

The mean corneal hysteresis was 10.56 ± 1.52 mm Hg in the study group and 11.16 ± 1.92 mm Hg in the control group (
P
= .022). The mean IOP was 14.9 ± 2.0 mm Hg in the study group and 14.1 ± 1.3 mm Hg in the control group (
P
= .003). Corneal hysteresis showed a significant, positive correlation with corneal resistance factor (
P
< .001,
r
= 0.851), IOPg (
P
= .044,
r
= 0.213), CCT (
P
< .001,
r
= 0.477), and IOP (
P
= .005,
r
= 0.295). Corneal hysteresis showed a significant, negative correlation with IOPcc (
P
= .001,
r
= −0.355), ACA (
P
= .005,
r
= −0.294), ACV (
P
= .019,
r
= −0.246), and ACD (
P
= .046,
r
= −0.211).

Conclusions:
Patients with childhood obesity have lower corneal hysteresis and higher IOPcc measurements when compared with healthy patients. Corneal tissue changes may occur in early life in childhood obesity, which could lead to ocular disease in the future.

Abstract
Macrophages are critical for the initiation and resolution of the inflammatory phase of wound healing. In diabetes, macrophages display a prolonged inflammatory phenotype preventing tissue repair. TLRs, particularly TLR4, have been shown to regulate myeloid-mediated inflammation in wounds. We examined macrophages isolated from wounds of patients afflicted with diabetes and healthy controls as well as a murine diabetic model demonstrating dynamic expression of TLR4 results in altered metabolic pathways in diabetic macrophages. Further, using a myeloid-specific mixed-lineage leukemia 1 (MLL1) knockout (Mll1f/fLyz2Cre+), we determined that MLL1 drives Tlr4 expression in diabetic macrophages by regulating levels of histone H3 lysine 4 trimethylation on the Tlr4 promoter. Mechanistically, MLL1-mediated epigenetic alterations influence diabetic macrophage responsiveness to TLR4 stimulation and inhibit tissue repair. Pharmacological inhibition of the TLR4 pathway using a small molecule inhibitor (TAK-242) as well as genetic depletion of either Tlr4 (Tlr4−/−) or myeloid-specific Tlr4 (Tlr4f/fLyz2Cre+) resulted in improved diabetic wound healing. These results define an important role for MLL1-mediated epigenetic regulation of TLR4 in pathologic diabetic wound repair and suggest a target for therapeutic manipulation.
Del inacabado al boceto como elemento estético: los "pencil tests" de Glen Keane

<p>En estudios como Walt Disney Animation, el dibujo abocetado que conforma las pruebas de lápiz o “pencil tests”, es depurado para obtener los fotogramas que darán lugar a la animación definitiva de acetatos. En el presente artículo analizaremos la presencia del trazo esbozado de Glen Keane en el resultado final de sus animaciones experimentales, Duet y Nephtali. En segundo lugar, veremos la transformación que sufre la línea de sus borradores a un contorno limpio y depurado, en las secuencias que forman parte de películas como La Bella y la Bestia o Tarzán. Y, por último, reflexionaremos cómo esta prueba de lápiz puede considerarse como definitiva dentro de animaciones de estética más comercial, en Pocahontas.</p>
La animación en bucle como dibujo vivo. Las repeticiones de Francis Alÿs

Published: March 2020

<p>Francis Alÿs, belga residente en México desde hace más de treinta años, es un artista contemporáneo con una trayectoria basada en lo performático, en la que también incluye una animación de naturaleza sencilla. La interacción entre sus dibujos en movimiento y el resto de su obra ubican a los primeros en un territorio interconectado a otros registros artísticos, a la vez que los transforma ampliando sus posibilidades dentro del dibujo. Esta relación provoca una difícil categorización que escapa a toda clasificación rígida. Por último, el hecho de que las animaciones seleccionadas se estructuren como bucle genera un tipo de visionado particular, en el que se juega con la desposesión y la ilusión de control de la imagen.</p>

<p>El anime se ha convertido en una de las grandes bazas de la diplomacia pública japonesa para publicitar el encanto de Japón. El gobierno japonés es consciente de este hecho, y apoya más que nunca el movimiento Cool Japan. Como resultado, algunos anime ya no exportan una visión personal de Japón, sino una hecha a medida. En relación con la creciente popularidad del anime, desde los años noventa del pasado siglo el peregrinaje otaku ha atraído turismo y revitalizado así la economía de las prefecturas. Podemos decir, por tanto, que el peregrinaje otaku es una consecuencia del éxito del anime. Sin embargo, recientemente ha habido un incremento en los anime cuyo principal objetivo es la promoción de prefecturas concretas. Mediante el estudio de algunos casos representativos, pretendemos investigar qué aspectos está interesado en promocionar Japón y cómo lo hace.</p>
Local stratopause temperature variabilities and their embedding in the global context
Authors: Eixmann Ronald , Matthias Vivien , Höffner Josef , Baumgarten Gerd , Gerding Michael 
Published: March 2020

Abstract. The stratopause is by definition the transition between the
stratosphere and mesosphere. During winter the circulation at mid-latitudes and
high latitudes in the stratosphere is mainly driven by quasi-stationary planetary waves (PWs), while the circulation in the
mesosphere is mainly driven by gravity waves (GWs). The question
arises of whether PWs or GWs dominate the variability of the
stratopause. The most famous and dramatic variability of the middle
atmosphere is a sudden stratospheric warming (SSW) generated by PWs
interacting with the polar vortex. A similar phenomenon but smaller in
magnitude and more regional is stratopause temperature enhancements
(STEs) initially observed by local measurements and generated by
breaking PWs. Thus it seems that PWs dominate the variability of the
stratopause. In this study we want to quantify to which extent quasi-stationary PWs contribute to the stratopause variability. To do that
we combine local lidar observations at Kühlungsborn
(54∘ N, 11∘ E) and Andenes (69∘ N,
16∘ E) with global MERRA-2 reanalysis data bringing the
local variability of the stratopause into the global
context. Therefore we compare the temperature time series at
Kühlungsborn and Andenes at 2 hPa, the altitude where STEs
maximize, with characteristics (amplitude and phase) of PWs with wave
numbers 1, 2 and 3. We found that for Kühlungsborn and Andenes
98 % of the local day-to-day variability of the
stratopause can be explained by the variability of PWs with wave
number 1, 2 and 3. Thus, the winter stratopause day-to-day
variability is highly dominated by the variability of PWs.
Dynamic upscaling of decomposition kinetics for carbon cycling models
Authors: Chakrawal Arjun , Herrmann Anke M. , Koestel John , Jarsjö Jerker , Nunan Naoise , Kätterer Thomas , Manzoni Stefano 
Published: March 2020

Abstract. The distribution of organic substrates and microorganisms in soils is spatially heterogeneous at the microscale. Most soil carbon cycling models do not account for this microscale heterogeneity, which may affect predictions of carbon (C) fluxes and stocks. In this study, we hypothesize that the mean respiration rate R‾ at the soil core scale (i) is affected by the microscale spatial heterogeneity of substrate and microorganisms and (ii) depends upon the degree of this heterogeneity. To theoretically assess the effect of spatial heterogeneities on R‾, we contrast heterogeneous conditions with isolated patches of substrate and microorganisms versus spatially homogeneous conditions equivalent to those assumed in most soil C models. Moreover, we distinguish between biophysical heterogeneity, defined as the nonuniform spatial distribution of substrate and microorganisms, and full heterogeneity, defined as the nonuniform spatial distribution of substrate quality (or accessibility) in addition to biophysical heterogeneity. Four common formulations for decomposition kinetics (linear, multiplicative, Michaelis–Menten, and inverse Michaelis–Menten) are considered in a coupled substrate–microbial biomass model valid at the microscale. We start with a 2-D domain characterized by a heterogeneous substrate distribution and numerically simulate organic matter dynamics in each cell in the domain. To interpret the mean behavior of this spatially explicit system, we propose an analytical scale transition approach in which microscale heterogeneities affect R‾ through the second-order spatial moments (spatial variances and covariances). The model assuming homogeneous conditions was not able to capture the mean behavior of the heterogeneous system because the second-order moments cause R‾ to be higher or lower than in the homogeneous system, depending on the sign of these moments. This effect of spatial heterogeneities appears in the upscaled nonlinear decomposition formulations, whereas the upscaled linear decomposition model deviates from homogeneous conditions only when substrate quality is heterogeneous. Thus, this study highlights the inadequacy of applying at the macroscale the same decomposition formulations valid at the microscale and proposes a scale transition approach as a way forward to capture microscale dynamics in core-scale models.
Brief communication: A fast vortex-based smearing correction for the actuator line
Authors: Meyer Forsting Alexander R. , Pirrung Georg R. , Ramos-García Néstor 
Published: March 2020

Abstract. The actuator line is a lifting line representation of aerodynamic surfaces in computational fluid dynamics applications but with non-singular
forces, which reduces the self-induced velocities at the line. The vortex-based correction by Meyer Forsting et al. (2019a)
recovers this missing induction and thus the intended lifting line behaviour of the actuator line. However, its computational cost exceeds that of
existing tip corrections and quickly grows with blade discretization. Here we present different methods for reducing its computational cost to the
level of existing corrections without jeopardizing the stability or accuracy of the original method. The cost is reduced by at least 98 %, whereas
the power is maximally affected by 0.8 % with respect to the original formulation. This accelerated smearing correction remains a dynamic
correction by modelling the variation in trailed vorticity over time. The correction is openly available (Meyer Forsting et al., 2019b).
