description: Cadmium telluride (CdTe) is an important material for photovoltaic applications because of its low cost and high efficiency. This efficiency may be increased further by alloying cadmium telluride with cadmium selenide (CdSe), to form cadmium selenium telluride (CdSeTe). Understanding the electronic and atomic structure of CdSeTe is important for understanding how to create the most efficient photovoltaic devices possible. In this study, density functional theory is used to model the behaviour of CdSeTe. An appropriate choice of functionals is developed, and these are used to analyse the properties of CdSeTe, including crystal structure, band structure, density of states, and molecular binding energies. Analysis of the results shows a good match between the predicted band gap and experimental results. The model is then used to explore the distribution of selenium within the CdSeTe, the free energy of mixing between CdTe and CdSe, and the formation energies of point defects with CdSeTe.

description: The article constitutes a presentation of the results of research devoted to the current trends in crisis PR. The authors of the work made an attempt to diagnose crisis prevention in a cross-section of two dimensions. On the one hand the perspective of business (survey of companies) was presented and on the other hand experts' opinions (survey of the leaders of public relations agencies) were shown. As a result of analyses a point model of an immune system, which takes into consideration the key instruments of crisis methodology (developed procedures in form of communication management book, dedicated anti-crisis structures in an organization, crisis team with a fixed membership and a system of communication trainings) was designed. Diagnosis of prevention measures of the leaders of Polish business — based on the years 2007–2017 showed major deficiencies in the degree of companies' preparation for the risk of crisis.

MDFRC item.

When using cephalopods as experimental animals, a number of factors, including morality, quality of information derived from experiments, and public perception, drives the motivation to consider welfare issues. Refinement of methods and techniques is a major step in ensuring protection of cephalopod welfare in both laboratory and field studies. To this end, existing literature that provides details of methods used in the collection, handling, maintenance, and culture of a range of cephalopods is a useful starting point when refining and justifying decisions about animal welfare. This review collates recent literature in which authors have used cephalopods as experimental animals, revealing the extent of use and diversity of cephalopod species and techniques. It also highlights several major issues when considering cephalopod welfare; how little is known about disease in cephalopods and its relationship to senescence and also how to define objective endpoints when animals are stressed or dying as a result of the experiment.

Percolation and cooperation with mobile agents: Geometric and strategy clusters

description: We study the conditions for persistent cooperation in an off-lattice model of mobile agents playing the Prisoner's Dilemma game with pure, unconditional strategies. Each agent has an exclusion radius rP, which accounts for the population viscosity, and an interaction radius rint, which defines the instantaneous contact network for the game dynamics. We show that, differently from the rP=0 case, the model with finite-sized agents presents a coexistence phase with both cooperators and defectors, besides the two absorbing phases, in which either cooperators or defectors dominate. We provide, in addition, a geometric interpretation of the transitions between phases. In analogy with lattice models, the geometric percolation of the contact network (i.e., irrespective of the strategy) enhances cooperation. More importantly, we show that the percolation of defectors is an essential condition for their survival. Differently from compact clusters of cooperators, isolated groups of defectors will eventually become extinct if not percolating, independently of their size.

description: MEXICAN PARROTLET Forpus cyanopygius insularis
(vs. F. c. cyanopygius / pallidus total score 7)
 Coloration.—Males have breast, belly, neck-sides and postocular region pale malachitegreen, somewhat glaucous, contrasting strongly with the yellowish-green or apple-green cheeks, throat, forehead and forecrown vs. apple-green underparts in slight contrast (if any) with the face colour (Figs. 11–12; Ridgway 1911, Grant 1965a, based on 21 male and 15 female insularis vs. 20 male and 31 female cyanopygius, www.inaturalist.org/observations/5258308, www.inaturalist.org/observations/5258315 [score 2]). This coloration is similar to male Pacific Parrotlet F. coelestis of western Ecuador and north-west Peru (e.g., www.hbw.com/ ibc/photo/pacific-parrotlet-forpus-coelestis/close-pacific-parrotlet and www.hbw.com/ibc/ photo/pacific-parrotlet-forpus-coelestis/male; the illustration of the later species in del Hoyo & Collar 2014 is inaccurate). Rump, lower back and greater coverts of males bright cerulean blue vs. bright turquoise-blue (Ridgway 1911, Grant 1965a [score 1]). Secondaries and proximal primaries darker and duller blue, edged cerulean blue vs. greenish blue (nearly cerulean blue) edged distally with pale yellowish green (Ridgway 1911 [score 2]). A. J. Grayson (in Lawrence 1872), Lawrence (1872), Ridgway (1888, 1911) and Grant (1965a) described the upperparts of both sexes of insularis as darker and more glaucous green (not scored, we are unable to discern this difference in the three insularis vs. six cyanopygius / pallidus specimens at IBUNAM). Grant (1965a) added that the flanks and undertail-coverts are the same colour as the breast / belly in all insularis males in his sample, but the detailed description of insularis by Ridgway (1911), the two IBUNAM specimens of adult male insularis, and our field photographs (e.g., Fig. 11) contradict that.
 Morphometrics.—Larger in all external measurements (score 2).
 Additional information.—Smith et al.’s (2012) molecular study found that insularis has diverged more from a common ancestor than cyanopygius / pallidus, consistent with a faster rate of divergence in small, isolated populations (Woolfit 2009), and the Bayesian modelling programme BP&B assigned the probability of insularis being a separate species as higher than 95%.

description: GOLDEN VIREO Vireo hypochryseus sordidus
 (vs. V. h. hypochryseus total score 5–6)
 Coloration.—Throat, breast, flanks and upperparts duller and greener in sordidus, especially in fresh plumage and when specimens collected in the same season are compared (score 1 or possibly 2, Grant 1965a, based on 30 male and 23 female sordidus vs. 44 male and 20 female hypochryseus). Grant (1965a) reported that Nelson’s (1898) claimed difference in bill colour is incorrect.
 Morphometrics.—Larger in all external measurements, especially tail length of both sexes and wing length of females (score 2), with a significantly shorter coracoid both absolutely and relatively (effect size almost reaches the threshold for score of 3, but we assign a score of 2) and a relatively shorter femur (not significantly different between taxa, whereas all external measurements are larger [not scored]). Arbeláez-Cortés et al. (2014) analysed the morphometrics of ten sordidus and 37 specimens from the rest of the range, and confirmed the larger size of sordidus.
 Additional information.— Arbeláez-Cortés et al. (2014) and Ortiz-Ramírez et al. (2018) reported reciprocal monophyly but shallow genetic divergence between these taxa.

Radial Velocities of Three Poorly Studied Clusters and the Kinematics of Open Clusters

description: We present radial velocities for stars in the field of the open star clusters Berkeley 44, Berkeley 81, and NGC 6802 from spectra obtained using the Wisconsin-Indiana-Yale-NOAO (WIYN) 3.5 m telescope. These clusters are of intermediate age (1-3 Gyr), located within the solar Galactocentric radius, and have no previous radial velocity measurements. We find mean radial velocities of -9.6 +/- 3.0 km s^-1, 48.1 +/- 2.0 km s^-1, and 12.4 +/- 2.8 km s^-1 for Be 44, Be 81, and NGC 6802, respectively. We present an analysis of radial velocities of 134 open clusters of a wide range of ages using data obtained in this study and the literature. Assuming the system of clusters rotates about the Galactic center with a constant velocity, we find older clusters exhibit a slower rotation and larger line-of-sight (LOS) velocity dispersion than younger clusters. The gradual decrease in rotational velocity of the cluster system with age is accompanied by a smooth increase in LOS velocity dispersion, which we interpret as the effect of heating on the open cluster system over time.

description: We have considered the underdamped motion of a Brownian particle in the presence of a correlated external random force. The force is modeled by an Ornstein-Uhlenbeck process. We investigate the fluctuations of the work done by the external force on the Brownian particle in a given time interval in the steady state. We calculate the large deviation functions as well as the complete asymptotic form of the probability density function of the performed work. We also discuss the symmetry properties of the large deviation functions for this system. Finally we perform numerical simulations and they are in a very good agreement with the analytic results.

description: Many species live in colonies that prosper for a while and then collapse.

We use birth and death chains in random environments to model such a population and to argue that random dispersion is a superior strategy for survival.

description: Optical localized states are usually defined as self-localized bistable packets of light which exist as independently controllable optical intensity pulses either in the longitudinal or transverse dimension of nonlinear optical systems. Here we provide the first experimental and analytical demonstration of the existence of longitudinal localized states which exist fundamentally in the phase of laser light. These robust and versatile phase bits can be individually nucleated and canceled in an injection-locked semiconductor laser operated in a neuron- like excitable regime and submitted to delayed feedback. The demonstration of their control opens the way to their use as phase information units in next generation coherent communication systems. We analyze our observations in terms of a generic model which confirms the topological nature of the phase bits and discloses their formal but profound analogy with Sine-Gordon solitons.

The Ξ-term influences the age of the universe. 훶 > 0 allows to avoid big bang singularity and black hole horizon formation. This solves the horizon problem without inflation. An atomic hypothesis solves the ultraviolet problem by explicit regularization. We give a prediction for cutoff length.
The dimming of Betelgeuse
Creators: name: Kervella, Pierre

Year: 2020

description: In January-February 2020, our red supergiant neighbor Betelgeuse experienced an exceptionally deep photometric minimum at visible wavelengths. As it emerges from behind the Sun after the boreal summer, the apparent brightness of Betelgeuse is still at a low level. Betelgeuse is surrounded by a molecular and dusty envelope, that has been detected in the thermal infrared domain, in particular using VLT/VISIR and VLTI/MIDI. More generally, the close environment of Betelgeuse has been monitored from the ultraviolet to radio wavelengths using a variety of facilities, including adaptive optics and long-baseline interferometry. I will present an (incomplete) overview of the existing observations of the environment of Betelgeuse, with an emphasis on the thermal infrared domain, and how they could shed light on the recent dimming event.

description: Analogues of stepping-stone models are considered where the site-space is continuous, the migration process is a general Markov process, and the type-space is infinite. Such processes were defined in previous work of the second author by specifying a Feller transition semigroup in terms of expectations of suitable functionals for systems of coalescing Markov processes. An alternative representation is obtained here in terms of a limit of interacting particle systems. It is shown that, under a mild condition on the migration process, the continuum-sites stepping-stone process has continuous sample paths. The case when the migration process is Brownian motion on the circle is examined in detail using a duality relation between coalescing and annihilating Brownian motion. This duality relation is also used to show that a random compact metric space that is naturally associated to an infinite family of coalescing Brownian motions on the circle has Hausdorff and packing dimension both almost surely equal to ½ and, moreover, this space is capacity equivalent to the middle -½ Cantor set (and hence also to the Brownian zero set).

description: A new cosmic scenario with gravitationally induced particle creation is proposed. In this model the Universe evolves from an early to a late time de Sitter era, with the recent accelerating phase driven only by the negative creation pressure associated with the cold dark matter component. The model can be interpreted as an attempt to reduce the so-called cosmic sector (dark matter plus dark energy) and relate the two cosmic accelerating phases (early and late time de Sitter expansions). A detailed thermodynamic analysis including possible quantum corrections is also carried out. For a very wide range of the free parameters, it is found that the model presents the expected behavior of an ordinary macroscopic system in the sense that it approaches thermodynamic equilibrium in the long run (i.e., as it nears the second de Sitter phase). Moreover, an upper bound is found for the Gibbons-Hawking temperature of the primordial de Sitter phase. Finally, when confronted with the recent observational data, the current `quasi'-de Sitter era, as predicted by the model, is seen to pass very comfortably the cosmic background tests.

description: We study the photon-photon correlation properties of two-photon transport in a one-dimensional waveguide coupled to a nonlinear cavity via a real-space approach. It is shown that the intrinsic dissipation of the nonlinear cavity has an important effect upon the correlation of the transported photons. More importantly, strongly correlated photons can be obtained in the transmitted photons even when the nonlinear interaction strength is weak in the cavity. The strong photon-photon correlation is induced by the Fano resonance involving destructive interference between the plane wave and bound state for two-photon transport.

description: The stochastic reactor models Partially Stirred Reactor (PaSR) and Partially Stirred Plug Flow Reactor (PaSPFR) have been investigated. These models are based on a simplified joint composition PDF transport equation. Analytic solutions for five different Cauchy problems for the PDF transport equation as given by the stochastic reactor models are presented. In all cases, molecular mixing in the stochastic reactor models is described by the LMSE mixing model. The analytic solutions have been found by combining the method of characteristics with a set of ordinary differential equations for the statistical moments to account for the functional dependence of the coefficients in the corresponding PDF transport equation. For each case an example problem is discussed to illustrate the behavior of the analytic solution.

 Coloration.—White mid-breast and mid-belly vs. rufous breast and belly in pallidus (Fig. 13; Grant 1965a, based on 43 male and 30 female lawrencii vs. 37 male and 18 female pallidus [not scored]). Among 18 lawrencii at IBUNAM, a few are washed warm on the breast, but are still usually paler than the palest pallidus. Even if there is warm colour across part of the breast, there is much white on the mid-breast and mid-belly. Examination of the ‘warmest’ specimens of lawrencii (P016585) revealed a diagnostic character not previously mentioned in the literature (e.g. Nelson 1898, Ridgway 1904, Grant 1965a): the colour of the underwing-coverts. In lawrencii, these are white or whitish, contrasting with the warm breast-sides, whereas pallidus has cinnamon / rufous underwing-coverts concolorous with the breast (score 3) (Fig. 14). Ear-coverts have significantly more white than black feathers vs. black and white feathers approximately equally prominent (score 2) (Fig. 13). One or other of these differences between lawrencii and pallidus is of somewhat similar magnitude to those between certain subspecies of, e.g., Coraya Pheugopedius coraya, Rufous-and-white Thryophilus rufalbus, Buff-breasted Cantorchilus leucotis, Carolina Thryothorus ludovicianus and White-browed Wrens T. albinucha, but in those cases there are zones of intergradation and smooth clines, whereas between lawrencii and pallidus the differences are abrupt and occur in both characters simultaneously. Grant (1965a) noted that in both plumage features, juveniles from the mainland approach those of Tres Marías birds.
 Morphometrics.—Longer wing, tail and, especially in females, bill (score 2) but tarsus relatively shorter (not significantly different in female and only slightly bigger in male [score 1]).

description: In a previous paper, we developed a technique for estimating the inner eccentricity in coplanar hierarchical triple systems on initially circular orbits, with comparable masses and with well separated components, based on an expansion of the rate of change of the Runge-Lenz vector. Now, the same technique is extended to non-coplanar orbits. However, it can only be applied to systems with ${I_{0}<39.23^{\circ}}$ or ${I_{0}>140.77^{\circ}}$, where ${I}$ is the inclination of the two orbits, because of complications arising from the so-called 'Kozai effect'. The theoretical model is tested against results from numerical integrations of the full equations of motion.

description: Molecular docking is a widely used Structure-Based method for drug discovery. Over the years, molecular docking methodologies have evolved to address several limitations, such as high errors in predicting pose and binding energy and approximations in the treatment of solvent molecules. These limitations were the starting point for my Ph.D. project, which involved using molecular dynamics (MD) and artificial neural networks to overcome these limitations. During the first year, I have addressed the problem of flexibility and high error in the calculation of the binding energy. From a thermodynamic point of view, water molecules can contribute to the formation of receptor-ligand complexes. During the second year, I evaluated the entropic contribution of water molecules in the binding site, developing a new docking protocol. During the third year, exploiting the studies started earlier on the entropy of water molecules in the active site, I developed a tool for binding site prediction. Moreover, I applied and validated the created protocol and other computational techniques to study the mechanism of action of the Sphingomyelin synthase system. [edited by Author]
description: Il docking molecolare è un metodo Structure-Based ampiamente utilizzato per la scoperta di farmaci. Nel corso degli anni, le metodologie di docking molecolare si sono evolute per affrontare diverse limitazioni, tra cui elevati errori nella previsione della posa e dell'energia di legame e le approssimazioni nel trattamento delle molecole di solvente. Queste limitazioni sono state il punto di partenza del mio progetto di dottorato, che ha visto l'utilizzo della dinamica molecolare (MD) e delle reti neurali artificiali per superare queste limitazioni. Durante il primo anno, ho affrontato il problema della flessibilità e dell'elevato errore nel calcolo dell'energia di legame. Da un punto di vista termodinamico, le molecole d'acqua possono contribuire alla formazione di complessi recettoreligando. Durante il secondo anno, ho valutato il contributo entropico delle molecole d'acqua nel sito di legame, sviluppando un nuovo protocollo di docking. Durante il terzo anno, sfruttando gli studi iniziati in precedenza sull'entropia delle molecole d'acqua nel sito attivo, ho sviluppato uno strumento per la predizione del sito di legame. Inoltre, ho applicato diverse tecniche computazionali per studiare il meccanismo d'azione del sistema della sfingomielina sintasi. [a cura dell'Autore]

description: We extend the quasi-steady state approximation (QSSA) as well with respect to the class of differential systems as with respect to the order of approximation. As an application we prove that the trimolecular autocatalator can be approximated by a fast bimolecular reaction system. Finally we describe a class of singularly perturbed systems for which the first order QSSA can easily be obtained.
First L band detection of hot exozodiacal dust with VLTI/MATISSE

description: For the first time we observed the emission of hot exozodiacal dust in L band. We used the new instrument MATISSE at the VLTI to detect the hot dust around ? Tuc at wavelengths between 3.37 ?m and 3.85 ?m. The dust-to-star flux ratio in L band amounts to 5 to 7 % and the spectral slope is ? = 3.92. We modelled the spectral energy distribution based on the new L band data alone and in combination with H band data (VLTI/PIONIER) published previously. In all cases we find 0.58 ?m grains of amorphous carbon to fit the ? Tuc observations the best, however, also nanometre or micrometre grains and other carbons or silicates reproduce the observations well. Since the H band data revealed a temporal variability, while our L band data were taken at a different epoch, we combine them in different ways. Depending on the approach, the best fits are obtained for a narrow dust ring at a stellar distance in the 0.1 au to 0.29 au range and thus with a temperature between 940 K and 1430 K.

description: The discovery of ThCr2Si2-type AxFe2-ySe2 (A = K, Rb, Cs and Tl) with Tc ~ 30K make much progress in iron-based superconducting field, but their multiple-phase separations are disadvantageous for understanding the origin. On the other hand, for small alkali metals, studies on (Li,Na)FeCu(S,Se)2 and NaFe2-δS2 shows that these compounds possess CaAl2Si2-type structure, implying that ThCr2Si2-type structure is unstable for small alkali-metal intercalated FeSe under high-temperature. Here we report a new intercalate Na0.65(1)Fe1.93(1)Se2 with Tc ~ 37 K, synthesized by low-temperature ammonothermal method. The notable finding is that the Na0.65(1)Fe1.93(1)Se2 shows a ThCr2Si2-type structure, which is the first instance of small-sized alkali metal intercalates without NH3 co-intercalation. Besides, the NH3-poor Na0.80(4)(NH3)0.60Fe1.86(1)Se2 and NH3-rich phase with Tcs at 45 K and 42 K are identified by tuning the concentration of Na-NH3 solutions. The modulation of interlayer spacing reveals the versatile evolution of structural stability and superconductivity in these intercalates.

description: We survey a variety of possible explications of the term "Individual Risk." These in turn are based on a variety of interpretations of "Probability," including Classical, Enumerative, Frequency, Formal, Metaphysical, Personal, Propensity, Chance and Logical conceptions of Probability, which we review and compare. We distinguish between "groupist" and "individualist" understandings of Probability, and explore both "group to individual" (G2i) and "individual to group" (i2G) approaches to characterising Individual Risk. Although in the end that concept remains subtle and elusive, some pragmatic suggestions for progress are made.

A new sample of X-ray selected narrow emission-line galaxies. I. The nature of optically elusive AGN

description: Using the 3XMM catalogue of serendipitous X-ray sources, and the SDSS-DR9 spectroscopic catalogue, we have obtained a new sample of X-ray selected narrow emission line galaxies. The standard optical diagnostic diagram and selection by hard X-ray luminosity expose a mismatch between the optically-based and X-ray-based classifications. The nature of these misclassified elusive AGN can be understood in terms of their broader X-ray and optical properties and leads to a division of this sub-sample into two groups. A little more than half are likely to be narrow-line Seyfert 1s (NLS1s), so misclassified because of the contribution of the Broad Line Region (BLR) to their optical spectra. The remainder have some of the properties of Seyfert 2 (Sy2) AGN; their optical elusiveness can be explained by optical dilution from the host galaxy plus a star-formation contribution and by their underluminous optical emission due to low accretion rates. Because some of the Sy2 sources have very low accretion rates, are unabsorbed, plus the fact that they lack broad optical emission lines, they are good candidates to be True Sy2 AGN.

Eccentricity generation in hierarchical triple systems: the planetary regime
Creators: name: Georgakarakos, Nikolaos
Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: In previous papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. We considered systems with well separated components and different initial setups (e.g. coplanar and non-coplanar orbits). However, the systems we examined had comparable masses. In the present paper, the validity of some of the formulae derived previously is tested by numerically integrating the full equations of motion for systems with smaller mass ratios (from ${10^{-3} \hspace{0.2cm} \mbox{to} \hspace{0.2cm} 10^{3}}$, i.e. systems with Jupiter-sized bodies). There is also discussion about HD217107 and its planetary companions.
