Transient High-energy Gamma-Rays and Neutrinos from Nearby Type II Supernovae
Authors: Wang Kai , Huang Tian-Qi , Li Zhuo 
Published: February 2019

Abstract
A dense wind environment (or circumstellar medium) may be ubiquitous in regular Type II supernovae (SNe II) before explosion, the interaction of which with the SN ejecta could result in a wind breakout event. The shock generated by the interaction of the SN ejecta and the wind can accelerate protons and subsequently high-energy gamma-rays and neutrinos could arise from inelastic pp collisions. In this work, we present detailed calculations of gamma-ray and neutrino production for regular SNe II. The calculations are executed by applying time-dependent evolution of dynamic and proton distributions so that the emission can be shown at different times. Our results show, for the SN 2013fs-like wind environment, multi-GeV and a few hundred TeV gamma-rays are detectable with a time window of several days at ≲2–3 Mpc by Fermi/LAT and the Cerenkov Telescopes Array during the ejecta–wind interaction, respectively, and can be detected at a further distance if the wind environment is denser. We find the contribution of wind breakouts of regular SNe II to diffusing neutrino flux is subdominant by assuming all SNe II are SN 2013fs-like, whereas for a denser wind environment the contribution could be conspicuous above 300 TeV.

Carrières de nobles hongrois à la cour de France sous l’Ancien Régime
Authors: Tóth Ferenc 
Published: February 2019

La cour de Versailles, œuvre de Louis XIV, représentait un moyen d’ascension sociale pour les nobles européens émigrés. Parmi ceux-ci, nous trouvons quelques aristocrates hongrois qui firent des carrières intéressantes durant la dernière période de l’Ancien Régime. L’émigration hongroise vers la France commença à la fin du xviie siècle et s’accrut sensiblement après la guerre d’indépendance hongroise (1703-1711). François II Rákóczi, allié oriental de Louis XIV, trouva un refuge au sein de la cour de celui-ci. Son intégration y fut facilitée par ses liens familiaux, mais il devait vivre à Versailles incognito et son entourage faisait face à des problèmes financiers. Finalement, il quitta la France en 1717 dans l’espoir de retrouver son trône. Les immigrés hongrois restant en France étaient intégrés dans les nouveaux régiments de hussards. Leur chef charismatique, le comte Ladislas de Berchény, tira parti de ses bonnes relations avec le beau-père de Louis XV, Stanislas Leszczynski, dont il obtint des charges importantes. Profitant de l’appui de la reine, il reçut à la fin de sa vie le bâton de maréchal. Un autre cas de carrière est présenté : celle du comte Valentin-Ladislas d’Esterhazy, fils d’un colonel de régiment de hussards français. Il gagna la sympathie et la confiance de Marie-Antoinette, qui le combla de ses grâces. En 1780, il fut nommé général et, en 1787, membre du Conseil de la guerre. Dans cette étude, nous présentons, par le biais de divers cas de figure, une synthèse sur l’histoire de l’immigration de nobles hongrois à la cour de France au temps des Lumières. À travers leurs liens avec des personnages influents, nous essayons de montrer les éléments et le fonctionnement des réseaux qui permettaient ou empêchaient leur carrière dans la cour royale.

Abstract
Yersinia enterocolitica causes a severe enteric infection in infants and young children. There is no vaccine approved for use in humans. We investigated the immunogenicity and protective capacity of Yersinia YopB, a conserved type III secretion system protein, alone or combined with LcrV in adult mice immunized intranasally. YopB or LcrV (5 μg) administered with the Escherichia coli double mutant heat-labile toxin (dmLT) adjuvant afforded modest (10–30%) protection against lethal Y. enterocolitica oral infection. The combination of YopB and LcrV (5 μg each) dramatically improved vaccine efficacy (70–80%). Additionally, it afforded complete protection against Y. pestis pulmonary infection. Immunization with YopB/LcrV+dmLT resulted in Ag-specific serum IgG, systemic and mucosal Ab-secreting cells, as well as IFN-γ, TNF-α, IL-2, IL-6, IL-17A, and KC production by spleen cells. Serum Abs elicited by YopB/LcrV+dmLT had enhanced bactericidal and opsonophagocytic killing activity. After Y. enterocolitica challenge, YopB/LcrV+dmLT–vaccinated mice exhibited intact intestinal tissue, active germinal centers in mesenteric lymph nodes, IgG+ and IgA+ plasmablasts in the lamina propria, and Abs in intestinal fluid. On the contrary, complete tissue destruction and abscesses were seen in placebo recipients that succumbed to infection. Mice immunized as infants with YopB+dmLT or LcrV+dmLT achieved 60% protection against lethal Y. enterocolitica infection, and vaccine efficacy increased to 90–100% when they received YopB/LcrV+dmLT. YopB+dmLT also afforded substantial (60%) protection when administered intradermally to infant mice. YopB/LcrV+dmLT is a promising subunit vaccine candidate with the potential to elicit broad protection against Yersinia spp.

Abstract. Tree allometric relationships are widely employed for estimating forest biomass
and production and are basic building blocks of dynamic vegetation models.
In tropical forests, allometric relationships are often modeled by fitting
scale-invariant power functions to pooled data from multiple species, an
approach that fails to capture changes in scaling during ontogeny and
physical limits to maximum tree size and that ignores interspecific
differences in allometry. Here, we analyzed allometric relationships of tree
height (9884 individuals) and crown area (2425) with trunk diameter for 162
species from the Barro Colorado Nature Monument, Panama. We fit
nonlinear, hierarchical models informed by species traits –
wood density, mean sapling growth, or sapling mortality – and assessed the
performance of three alternative functional forms: the scale-invariant power
function and the saturating Weibull and generalized Michaelis–Menten (gMM)
functions. The relationship of tree height with trunk diameter was best fit
by a saturating gMM model in which variation in allometric parameters was
related to interspecific differences in sapling growth rates, a measure of
regeneration light demand. Light-demanding species attained taller heights at
comparatively smaller diameters as juveniles and had shorter asymptotic
heights at larger diameters as adults. The relationship of crown area with
trunk diameter was best fit by a power function model incorporating a weak
positive relationship between crown area and species-specific wood density.
The use of saturating functional forms and the incorporation of functional
traits in tree allometric models is a promising approach for improving estimates
of forest biomass and productivity. Our results provide an improved basis for
parameterizing tropical plant functional types in vegetation models.

Published: February 2019

There have been studied kinetic objective laws of ethylbenzol oxidation (RH) and decomposition of a-phenylethyl of hydroperoxide (ROOH) in the presence of cationic surface-active substance-cetyltrimethylammonia of bromide (CTAB) and bis-(chacetylacetonate) of cobalt (Co(acac)2). The combination of Co(acac)2 (0,1 mM) with CTAB (1mM) is a hidheffective synergetic catalytic system: the oxidation of RH at 600C is characterized by a high rate of absorption O2 and low stationar concentration of ROOH, the main product of oxidation RH in this system is acetophenon. The effective energy of activization the decomposition of ROOH is Eeff=45,5 kJ/mol, the outlet of radicals-e=0,09. It has been made a supposition that at the oxidation of ethylbenzol by the oxygen from the air, the mecanism of cobalt-bromide catalysis is realized in the system CTAB-Co(acac)2; the concentration of reagents (ROOH, Co(II), Br) in microagregates CTAB at a small brutto concentrations of the catalysator brings to the rise of the rate of ROOH decomposition and to the fall of the radicals outlet into volume of oxidating
Enhancing fitness, enjoyment, and physical self-efficacy in primary school children: a DEDIPAC naturalistic study
Authors: Vitali Francesca , Robazza Claudio , Bortoli Laura , Bertinato Luciano , Schena Federico , Lanza Massimo 
Published: February 2019

Background
Physical activity (PA) (e.g., sport, physical education) promotes the psychophysical development of children, enhances health and wellbeing, offers opportunities for enjoyable experiences, and increases self-efficacy.

Methods
In the DEDIPAC framework, we conducted a naturalistic, cross-sectional study to evaluate the effects of a school-based, long-term intervention on fitness (i.e., cardiovascular endurance, muscular strength, flexibility, speed, and finger dexterity), body mass index (BMI), PA levels, sedentary levels, enjoyment, and physical self-efficacy in primary school children. A group of Italian children (41 boys and 39 girls, aged 10–11 years) involved in the project—named “Più Sport @ Scuola” (PS@S)—was compared with a group of children (41 boys and 39 girls) of the same age not involved in the project.

Results
After a four-year long attendance to the PS@S project, participants reported higher scores of cardiovascular endurance, muscular strength, enjoyment, and physical self-efficacy compared to children not involved in the project. Correlation analysis results showed that muscular strength scores correlated positively with BMI, PA levels, and enjoyment. Flexibility of the upper body was positively related to physical self-efficacy, and negatively related to speed and BMI.

Conclusions
Findings suggest that the PS@S project enhanced fitness level, enjoyment, and physical self-efficacy of children.
Mathematical Analysis of a Fractional-order "SIR" Epidemic Model with a General Nonlinear Saturated Incidence Rate in a Chemostat
Authors: Hajji Miled El 
Published: February 2019

In the present work, a fractional-order differential equation based on the Susceptible-Infected- Recovered (SIR) model with nonlinear incidence rate in a continuous reactor is proposed. A profound qualitative analysis is given. The analysis of the local and global stability of equilibrium points is carried out. It is proved that if the basic reproduction number R > 1 then the disease-persistence (endemic) equilibrium is globally asymptotically stable. However, if R ≤ 1, then the disease-free equilibrium is globally asymptotically stable. Finally, some numerical tests are done in order to validate the obtained results.
The Gasca-Maeztu Conjecture for n = 4
Authors: Vardanyan Vahagn 
Published: February 2019

We consider planar GCn node sets, i.e., n-poised sets whose all n-fundamental polynomials are products of n linear factors. Gasca and Maeztu conjectured in 1982 that every such set possesses a maximal line, i.e., a line passing through n + 1 nodes of the set. Till now the conjecture is confirmed to be true for n ≤ 5. The case n = 5 was proved recently by H. Hakopian, K. Jetter, and G. Zimmermann (Numer. Math. 127 (2014) 685{713). In this paper we bring a short and simple proof of the conjecture for n = 4.

Recent Advances in Carbon‐Based Metal‐Free Electrocatalysts
Authors: Paul Rajib , Zhu Lin , Chen Hao , Qu Jia , Dai Liming 
Published: February 2019

AbstractPrecious noble metals (such as Pt, Ir) and nonprecious transition metals (e.g., Fe, Co), including their compounds (e.g., oxides, nitrides), have been widely investigated as efficient catalysts for energy conversion, energy storage, important chemical productions, and many industrial processes. However, they often suffer from high cost, low selectivity, poor durability, and susceptibility to gas poisoning with adverse environmental issues. As a low‐cost alternative, the first carbon‐based metal‐free catalyst (C‐MFC based on N‐doped carbon nanotubes) was discovered in 2009. Since then, various C‐MFCs have been demonstrated to show similar or even better catalytic performance than their metal‐based counterparts, attractive energy conversion and storage (e.g., fuel cells, metal–air batteries, water splitting), environmental remediation, and chemical production. Enormous progress has been achieved while the number of publications still rapidly increases every year. Herein, a critical overview of the very recent advances in this rapidly developing field during the last couple of years is presented.
Ferroelectric Properties of Perovskite Thin Films and Their Implications for Solar Energy Conversion

Published: February 2019

AbstractWhether or not methylammonium lead iodide (MAPbI3) is a ferroelectric semiconductor has caused controversy in the literature, fueled by many misunderstandings and imprecise definitions. Correlating recent literature reports and generic crystal properties with the authors' experimental evidence, the authors show that MAPbI3 thin‐films are indeed semiconducting ferroelectrics and exhibit spontaneous polarization upon transition from the cubic high‐temperature phase to the tetragonal phase at room temperature. The polarization is predominantly oriented in‐plane and is organized in characteristic domains as probed with piezoresponse force microscopy. Drift‐diffusion simulations based on experimental patterns of polarized domains indicate a reduction of the Shockley–Read–Hall recombination of charge carriers within the perovskite grains due to the ferroelectric built‐in field and allow reproduction of the electrical solar cell properties.

Published: February 2019

AbstractOrganic semiconductors are the centerpiece of several vibrant research fields from single‐molecule to organic electronics, and they are finding increasing use in bioelectronics and even classical polymer technology. The versatile chemistry and broad range of electronic functionalities of conjugated materials enable the bridging of length scales 15 orders of magnitude apart, ranging from a single nanometer (10−9 m) to the size of continents (106 m). This work provides a taste of the diverse applications that can be realized with organic semiconductors. The reader will embark on a journey from single molecular junctions to thin film organic electronics, supramolecular assemblies, biomaterials such as amyloid fibrils and nanofibrillated cellulose, conducting fibers and yarns for e‐textiles, and finally to power cables that shuffle power across thousands of kilometers.

Published: February 2019

AbstractVan der Waals (vdW) epitaxy allows the fabrication of various heterostructures with dramatically released lattice matching conditions. This study demonstrates interface‐driven stacking boundaries in WS2 using epitaxially grown tungsten disulfide (WS2) on wrinkled graphene. Graphene wrinkles function as highly reactive nucleation sites on WS2 epilayers; however, they impede lateral growth and induce additional stress in the epilayer due to anisotropic friction. Moreover, partial dislocation‐driven in‐plane strain facilitates out‐of‐plane buckling with a height of 1 nm to release in‐plane strain. Remarkably, in‐plane strain relaxation at partial dislocations restores the bandgap to that of monolayer WS2 due to reduced interlayer interaction. These findings clarify significant substrate morphology effects even in vdW epitaxy and are potentially useful for various applications involving modifying optical and electronic properties by manipulating extended 1D defects via substrate morphology control.

Published: February 2019

AbstractNowadays, aiming to fight against environmental pollution and energy crisis, a great amount of effort has been performed on self‐powered devices. Herein, assembling a wind‐driven triboelectric nanogenerator (TENG) and a pressure sensitive elastic polyimide (PI)/reduced graphene oxide (rGO) foam together, a self‐powered pressure sensor system has been designed and investigated. Employing Ag nanoparticles and nylon film as electrode and vibration membrane, the TENG can generate desirable output. Meanwhile, the PI/rGO foam acts as the pressure sensitive unit. Integrating a bulk of PI/rGO foam (14 mm × 14 mm × 30 mm), the TENG could generate output voltage and current up to 130 V and 7.5 µA with an effective working area of 100 mm × 15 mm. Additionally, the as‐fabricated device presents various stress sensing scopes and sensitivities, when different heights of foams are integrated on the TENG. The self‐powered pressure sensor achieves a great combination between new clean energy resources and traditional pressure sensor.
