description: Powerful telescopes equipped with multi-fibre or integral field spectrographs combined with detailed models of stellar atmospheres and automated fitting techniques allow for the analysis of large number of stars. These datasets contain a wealth of information that require new analysis techniques to bridge the gap between observations and stellar evolution models. To that end, we develop BONNSAI (BONN Stellar Astrophysics Interface), a Bayesian statistical method, that is capable of comparing all available observables simultaneously to stellar models while taking observed uncertainties and prior knowledge such as initial mass functions and distributions of stellar rotational velocities into account. BONNSAI can be used to (1) determine probability distributions of fundamental stellar parameters such as initial masses and stellar ages from complex datasets, (2) predict stellar parameters that were not yet observationally determined and (3) test stellar models to further advance our understanding of stellar evolution. An important aspect of BONNSAI is that it singles out stars that cannot be reproduced by stellar models through $χ^{2}$ hypothesis tests and posterior predictive checks. BONNSAI can be used with any set of stellar models and currently supports massive main-sequence single star models of Milky Way and Large and Small Magellanic Cloud composition. We apply our new method to mock stars to demonstrate its functionality and capabilities. In a first application, we use BONNSAI to test the stellar models of Brott et al. (2011a) by comparing the stellar ages inferred for the primary and secondary stars of eclipsing Milky Way binaries. Ages are determined from dynamical masses and radii that are known to better than 3%. We find that the stellar models reproduce the Milky Way binaries well. BONNSAI is available through a web-interface at http://www.astro.uni-bonn.de/stars/bonnsai.

description: Gamma-ray bursts (GRBs) show a bimodal distribution of durations, separated at a duration of ~2 s. Observations have confirmed the association of long GRBs with the collapse of massive stars. The origin of short GRBs is still being explored. We examine constraints on the emission region size in short and long GRBs detected by Fermi/GBM. We find that the emission region size during the prompt emission, R, and the burst duration, T$_{90}$, are consistent with the relation R ~ c x T$_{90}$, for both long and short GRBs. We find the characteristic size for the prompt emission region to be ~2 x 10$^{10}$ cm, and ~4 x 10$^{11}$ cm for short and long GRBs, respectively.

Loop quantum cosmological model from ADM Hamiltonian

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The loop quantum cosmological model from ADM Hamiltonian is studied in this paper. We consider the spatially flat homogeneous FRW model. It turns out that the modified Friedmann equation keeps the same form as the APS LQC model. However, the critical matter density for the bounce point is only a quarter of the previous APS model, i.e. $ρ_{cL}=\frac{ρ_c}{4}$. This is interesting because the lower critical bounce density means the quantum gravity effects will get involved earlier than the previous LQC model. Besides, the lower critical density also means the detection of quantum gravity effects easier than the previous model.

description: The present study examined discrimination attributions in the psychological well-being of Black adolescents. Findings are based on a representative sample of 810 African American and 360 Caribbean Black youth, aged 13 to 17, who participated in the National Survey of American Life (NSAL). Youth completed measures of perceived discrimination, discrimination attributions, depressive symptoms, self-esteem and life satisfaction. Approximately half the youth attributed discrimination to race/ethnicity (43%), followed by age (17%), physical appearance (16.5%) and gender (7.5%) and there were no ethnic, gender or age differences regarding discrimination attributions. Key findings suggest that the association between perceived discrimination and psychological did not vary according to discrimination attribution, which implies that discrimination is harmful for Black youth regardless of the attribution.

description: This article reviews empirical and theoretical contributions to a multidisciplinary understanding of peer influence processes in adolescence over the past decade. Five themes of peer influence research from this decade were identified, including a broadening of the range of behaviors for which peer influence occurs, distinguishing the sources of influence, probing the conditions under which influence is amplified/attenuated (moderators), testing theoretically based models of peer influence processes (mechanisms), and preliminary exploration of behavioral neuroscience perspectives on peer influence. This review highlights advances in each of these areas, underscores gaps in current knowledge of peer influence processes, and outlines important challenges for future research.

description: The Remote Associates Test (RAT) is a widely used test for measuring creativity, specifically the ability to make associations. The Remote Associates Test normally takes a linguistic form: given three words, the participant is asked to come up with a fourth word associated with all three of them. While visual creativity tests do exist, no creativity test to date can be given in both a visual and linguistic form. Such a test would allow the study of differences between various modalities, in the context of the same creative process. In this paper, a visual version of the well-known Remote Associates Test is constructed. This visual RAT is validated in relation to its linguistic counterpart.

description: Il lavoro di tesi muove da una tensione esplorativa volta ad analizzare il rapporto esistente tra l’immagine femminile e la terra e come esso venga filtrato e plasmato sulla pagina da uno scrittore d’eccezione come Cesare Pavese e da una suggestione letteraria, nata da una lettura di un saggio del 1910 di Sibilla Aleramo, che descrivendo la situazione difficile della donna in quegli anni, la definisce quale “energia incognita”, metafora che potrebbe trovare una sua dimensione anche in un orizzonte complesso ed estremamente caleidoscopico quale quello della scrittura pavesiana. La tesi si dipana così come una rete labirintica attraverso le scritture di Pavese tra poesie e prose, provando a delineare percorsi possibili e ponti di rimando che intrecciano una scrittura all’altra schiudendo i nuclei tematici centrali. .. [a cura dell'Autore]
description: The work on Pavese’s novels deals with the relationship between the image of women and the homeland, and also it analyzes a woman like as an “incognita energy”, as Sibilla Aleramo said in the 1910. It demonstrates the extraordinary capacity of Cesare Pavese to give to the femal character the ability to tell her stories also in first person and to interpret the difficult path of emancipation which realizes the passage of women’s role from the “object of desire” to the “desiring subject”. This work analyzes also the relationship between Cesare Pavese and Alba de Cèspedes, specially the novel named Nessuno torna indietro (1938) and Tra donne sole (1948) especially in relation to the issues related to the fascist regime. This thesis deals with the poetical matter, basing on the analysis of the importance of a word and its meaning, symbolical and mythological too: first, Lavorare stanca (1936), and afterwards “La Terra e la Morte” (1945). The analysis tries to give a possible interpretation of interlocutor whom poet it will appeal in his poetry; finally it seems to be a Poetry, precisely “The Art or a Woman- Poetry”. This work also tries to explain how the author has made a kind of “mimesis” between reality and writing, such as to render the complexity of human existence. [edited by Author]

description: We construct the D3-brane dual to a $k$-quark of $\mathcal{N}=4$ super-Yang-Mills theory in the totally symmetric representation of $SU(N)$, undergoing arbitrary motion. Our method of construction generalizes previous work by Mikhailov, and proceeds by shooting light rays inward from the anti-de Sitter boundary, to trace out the brane embedding. We expect this method to have wider relevance, and provide evidence for this by showing that it correctly reproduces the known D5-brane embeddings dual to totally antisymmetric $k$-quarks. As an application of our solutions, we compute the energy of the D3-brane and extract from it the $k$-quark's intrinsic energy and rate of radiation. The result matches expectations based on previous calculations, and makes contact with the exact Bremsstrahlung function for the fundamental representation.

description: We study numerical integration of Hölder-type functions with respect to weights on the real line. Our study extends previous work by F. Curbera, [2] and relies on a connection between this problem and the approximation of distribution functions by empirical ones. The analysis is based on a lemma which is important within the theory of optimal designs for approximating stochastic processes. As an application we reproduce a variant of the well known result for weighted integration of Brownian paths, see e.g., [8].

description: Aim & Hypothesis: The objective of the present investigation is to determine the influence of the combined effect of both the transmucosal abutment height (TmAH) and restorative emergence angles (REA) on peri-implant marginal bone loss (MBL) after the first year of remodeling in bone level implants. It was hypothesized that by increasing the TmAH, the known effects of REA on peri-implant bone loss progression could be mitigated. Materials & Methods: Implants with diagnostic radiographs taken 12-18 months after crown placement (T0) and at least one year later (T1) were included in this retrospective analysis. TmAH and REA were measured. Sites were separated into four groups: Long-Gradual (LG) with TmAH >2mm with REA <30˚, Long-Abrupt (LA) with TmAH >2mm with REA >30˚, Short-Gradual (SG) with TmAH <2mm with REA <30˚, and Short-Abrupt (SA) with TmAH <2mm with REA >30˚. MBL was calculated, and multiple linear regression analysis was performed to control for patient-level (age, gender, diabetes, smoking status, maintenance visits, history of periodontitis) and implant/prosthesis level factors (implant site, diameter, length, brand, connection, retention type). Subsequently, a multiple binary logistic regression model was performed to identify what factor (REA or TmAH) had a more significant impact on the probability of MBL. Results: 192 implants pertaining to 119 patients were included. When comparing Mean MBL, Group played a significant role (p<0.001), with Group SA experiencing on average 0.48mm (95% CI: 0.25 - 0.71, p<0.001), 0.43mm (95% CI: 0.18 - 0.68, p=0.001), and 0.25mm (95% CI: 0.00 - 0.45, p=0.013) greater MBL compared to Group LG, Group LA, and Group SG respectively. Results also revealed that Group was a significant factor impacting the development of periimplantitis (p=0.041), with Group SA displaying a roughly 4x greater likelihood of having peri-implantitis (PI) diagnosed compared to Group LA (OR: 4.19; p= 0.013) and Group LG (OR: 4.04; p=0.091). Additionally, every 1 mm increase in TmAH decreased the probability of MBL >0mm (pMBL>0) by 51% (OR=0.49; p=0.015). Finally, the influence of REA on pMBL>0 was not found to be significant when adjusted for TmAH. Conclusions: Abutment height greater than 2mm may play a role in reducing the experience of PI and MBL related to abrupt REA around bone-level implants. REA was only a significant factor when TmAH was less than 2mm. The probability of MBL was found to have an inverse relationship with TmAH and have no significant relationship with REA.

description: We present experimental data and numerical modeling of a nonlinear phenomenon in active magnetic microbead rheology that appears to be common to entangled polymer solutions (EPS). Dynamic experiments in a modest range of magnetic forces show: 1. a short-lived high viscosity plateau, followed by 2. a bead acceleration phase with a sharp drop in apparent viscosity, and 3. a terminal steady state that we show resides on the shear-thinning slope of the steady-state flow curve from cone and plate data. This latter feature implies a new protocol to access the nonlinear steady-state flow curve for many biological EPS only available in microliter-scale volumes. We solve the moment-closure form of the Rolie-Poly kinetic model for EPS hydrodynamics, together with a decoupling approximation that obviates the need for a full 3D flow solver, and show that the model qualitatively reproduces the dynamic experimental sequence above. In this way, we explain the phenomenon in terms of entangled polymer physics, and show how the nonlinear event (acceleration and termination on the shear-thinning response curve) is tunable by the interplay between molecular-scale mechanisms (relaxation via reptation and chain retraction) and magnetic force controls. The experimental conditions mimic movement of cilia tips, bacteria, and sperm in mucus barriers, implying a physiological relevance of the phenomenon, and compelling further development of the fully coupled, 3D flow-microstructure model to achieve quantitative accuracy.

description: During X-ray computed tomography (CT) scanning, metallic implants carrying with patients often lead to adverse artifacts in the captured CT images and then impair the clinical treatment. Against this metal artifact reduction (MAR) task, the existing deep-learning-based methods have gained promising reconstruction performance. Nevertheless, there is still some room for further improvement of MAR performance and generalization ability, since some important prior knowledge underlying this specific task has not been fully exploited. Hereby, in this paper, we carefully analyze the characteristics of metal artifacts and propose an orientation-shared convolution representation strategy to adapt the physical prior structures of artifacts, i.e., rotationally symmetrical streaking patterns. The proposed method rationally adopts Fourier-series-expansion-based filter parametrization in artifact modeling, which can better separate artifacts from anatomical tissues and boost the model generalizability. Comprehensive experiments executed on synthesized and clinical datasets show the superiority of our method in detail preservation beyond the current representative MAR methods.

description: The aim of the paper is to provide the mathematical foundation of effective numerical algorithms for the optimal design of periodic binary gratings. Special attention is paid to fast and reliable methods for the computation of diffraction efficiencies and of the gradients of certain functionals with respect to the parameters of the non-smooth grating profile. The methods are based on a generalized finite element discretization of strongly elliptic variational formulations of quasi periodic transmission problems for the Helmholtz equation in a bounded domain coupled with boundary integral representations in the exterior. We prove uniqueness and existence results for quite general situations and analyse the convergence of the numerical solutions. Furthermore, explicit formulas for the partial derivatives of the reflection and transmission coefficients with respect to the parameters of a binary grating profile are derived. Finally, we briefly discuss the implementation of a gradient type algorithm for solving optimal design problems and present some numerical results.

description: Consider the problem of control selection in complex dynamical and environmental scenarios where model predictive control (MPC) proves particularly effective. As the performance of MPC is highly dependent on the efficiency of its incorporated search algorithm, this work examined hill climbing as an alternative to traditional systematic or random search algorithms. The relative performance of a candidate hill climbing algorithm was compared to representative systematic and random algorithms in a set of systematic tests and in a real-world control scenario. These tests indicated that hill climbing can provide significantly improved search efficiency when the control space has a large number of dimensions or divisions along each dimension. Furthermore, this demonstrated that there was little increase in search times associated with a significant increase in the number of control configurations considered.

description: Hospital nurses have one of the highest work-related injury rates in the United States. Yet, approaches to improving employee safety have generally focused on attempts to modify individual behavior through enforced compliance with safety rules and mandatory participation in safety training. We examined a theoretical model that investigated the impact on nurse injuries (back injuries and needlesticks) of critical structural variables (staffing adequacy, work engagement, and work conditions) and further tested whether safety climate moderated these effects. A longitudinal, non-experimental, organizational study, conducted in 281 medical-surgical units in 143 general acute care hospitals in the United States. Work engagement and work conditions were positively related to safety climate, but not directly to nurse back injuries or needlesticks. Safety climate moderated the relationship between work engagement and needlesticks, while safety climate moderated the effect of work conditions on both needlesticks and back injuries, although in unexpected ways. DISCUSSION AND IMPACT ON INDUSTRY: Our findings suggest that positive work engagement and work conditions contribute to enhanced safety climate and can reduce nurse injuries.

description: In order to link infrared observations of dust formed during planet formation in debris disks to mid-infrared spectroscopic data of planetary materials from differentiated terrestrial and asteroidal bodies, we obtained absorption spectra of a representative suite of terrestrial crustal and mantle materials, and of typical Martian meteorites. A series of debris disk spectra characterized by a strong feature in the 9.0-9.5 micron range (HD23514, HD15407a, HD172555 and HD165014), is comparable to materials that underwent shock, collision or high temperature events. These are amorphous materials such as tektites, SiO2-glass, obsidian, and highly shocked shergottites as well as inclusions from mesosiderites (Group A). A second group (BD+20307, Beta Pictoris, HD145263, ID8, HD113766, HD69830, P1121, and Eta Corvi) have strong pyroxene and olivine bands in the 9-12 micron range and is very similar to ultramafic rocks (e.g. harzburgite, dunite)(Group B). This could indicate the occurrence of differentiated materials similar to those in our Solar System in these other systems. However, mixing of projectile and target material, as well as that of crustal and mantle material has to be taken into account in large scale events like hit-and-run and giant collisions or even large-scale planetary impacts. This could explain the olivine-dominated dust of group B. The crustal-type material of group A would possibly require the stripping of upper layers by grazing-style hit-and run encounters or high energy events like evaporation/condensation in giant collisions. In tidal disruptions or the involvement of predominantly icy/water bodies the resulting mineral dust would originate mainly in one of the involved planetesimals. This could allow attributing the observed composition to a specific body (such as e.g. Eta Corvi).

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The surface brightness distribution in the majority of stellar galactic discs falls off exponentially. Often what lies beyond such a stellar disc is the neutral hydrogen gas whose distribution also follows a nearly exponential profile at least for a number of nearby disc galaxies. Both the stars and gas are commonly known to host lopsided asymmetry especially in the outer parts of a galaxy. The role of such asymmetry in the dynamical evolution of a galaxy has not been explored so far. Following Lindblad's original idea of kinematic density waves, we show that the outer part of an exponential disc is ideally suitable for hosting lopsided asymmetry. Further, we compute the transport of angular momentum in the combined stars and gas disc embedded in a dark matter halo. We show that in a pure star and gas disc, there is a transition point where the free precession frequency of a lopsided mode, $Ω-κ$, changes from retrograde to prograde and this in turn reverses the direction of angular momentum flow in the disc leading to an unphysical behaviour. We show that this problem is overcome in the presence of a dark matter halo, which sets the angular momentum flow outwards as required for disc evolution, provided the lopsidedness is leading in nature. This, plus the well-known angular momentum transport in the inner parts due to spiral arms, can facilitate an inflow of gas from outside perhaps through the cosmic filaments.

description: A systematic study of energy conservation for extended magnetohydrodynamic (MHD) models that include Hall terms and electron inertia is performed. It is observed that commonly used models do not conserve energy in the ideal limit, i.e., when viscosity and resistivity are neglected. In particular, a term in the momentum equation that is often neglected is seen to be needed for conservation of energy.

description: For functions belonging to the classes $C^{2}[0, 1]$ and $C^{3}[0, 1]$, we establish the lower estimate with an explicit constant in approximation by Bernstein polynomials in terms of the second order Ditzian-Totik modulus of smoothness. Several applications to some concrete examples of functions are presented.

description: To understand how neighborhoods influence the development of youth violence, we investigated intrapersonal mediators of the relationship between neighborhood disadvantage and youth violence trajectories between ages 11 and 18. The hypothesized mediators included indicators of social bonding (belief in conventional values, involvement in school activities, religious engagement, and commitment to traditional goals) and psychological distress.

description: Photonic qubits should be controllable on-chip and noise-tolerant when transmitted over optical networks for practical applications. Furthermore, qubit sources should be programmable and have high brightness to be useful for quantum algorithms and grant resilience to losses. However, widespread encoding schemes only combine at most two of these properties. Here, we overcome this hurdle by demonstrating a programmable silicon nano-photonic chip generating frequency-bin entangled photons, an encoding scheme compatible with long-range transmission over optical links. The emitted quantum states can be manipulated using existing telecommunication components, including active devices that can be integrated in silicon photonics. As a demonstration, we show our chip can be programmed to generate the four computational basis states, and the four maximally-entangled Bell states, of a two-qubits system. Our device combines all the key-properties of on-chip state reconfigurability and dense integration, while ensuring high brightness, fidelity, and purity.

description: В статье представлена характеристика поверхностных вод одного из самых отдаленных заполярных районов Ямало-Ненецкого автономного округа (ЯНАО). Приведены сведения об уровне антропогенной нагрузки, связанной с использованием водных ресурсов Ямальского района. Выявлено, что по объему сточных вод, приходящихся на 1 жителя, в том числе загрязненных и сточных вод сбрасываемых без очистки, Ямальский район занимает последнее место как среди субъектов Уральского федерального округа, так и среди муниципальных районов ЯНАО. Показано, что проводимых исследований недостаточно для выявления уровня загрязнения поверхностных вод, а также тенденций их изменения. Необходимы более продолжительные временные периоды наблюдений. Рассмотрены основные мероприятия по охране и предупреждению негативного воздействия на водные объекты Ямальского района.
description: The characteristic of the surface water of one of the most remote Polar areas of Yamal-Nenets Autonomous Okrug (YNAA) is presented in the article. It is revealed that the Yamal Area takes the last place, both among the subjects of the Ural Federal District, and the municipal areas of Yamal-Nenets Autonomous Okrug on the volume of the sewage per a resident including the polluted water and the sewage which are dumped without cleaning. It is shown that the conducted research is not enough for the identification of the level of the surface water pollution, and the tendencies of their change. Longer time periods for observations are needed. The main activities on the protection and prevention of the negative impact on the water objects of the Yamal Area are considered.
Microscopic pair potentials and the physical properties of the condensed phase of parahydrogen

description: Equilibrium physical properties of the solid and liquid phases of parahydrogen, computed by first principle computer simulations, are compared for different choices of pairwise, spherically symmetric intermolecular potentials. The most recent ab initio potential [Patkowski et al., J. Chem. Phys., 2008, 129, 094304], which has a stiffer repulsive core than the commonly used Silvera-Goldman, yields results for structural quantities in better agreement with the most recent experimental measurements, while possibly overestimating the kinetic energy per molecule by as much as 10%. Altogether, the comparison between theory and the available experimental evidence suggests that the potential of Patkowski et al. may be a better choice for simulations of condensed phases of parahydrogen at moderate pressure.

A scaling relation between proton-nucleus and nucleus-nucleus collisions

description: It is recently discovered that at high multiplicy, the proton-nucleus ($pA$) collisions give rise to two particle correlations that are strikingly similar to those of nucleus-nucleus ($AA$) collisions at the same multiplicity, although the system size is smaller in $pA$. Using an independent cluster model and a simple conformal scaling argument, where the ratio of the mean free path to the system size stays constant at fixed multiplicity, we argue that flow in $pA$ emerges as a collective response to the fluctuations in the position of clusters, just like in $AA$ collisions. With several physically motivated and parameter free rescalings of the recent LHC data, we show that this simple model captures the essential physics of elliptic and triangular flow in $pA$ collisions.

Efficient exciton generation in a semiconductor quantum dot-metal nanoparticle composite structure using conventional chirped pulses

description: We consider a nanostructure consisting of a semiconductor quantum dot coupled to a metal nanoparticle, and show with numerical simulations that the exciton state of the quantum dot can be robustly generated from the ground state even for small interparticle distances, using conventional chirped pulses with Gaussian and hyperbolic secant envelopes. The asymmetry observed in the final exciton population with respect to the chirp sign of the applied pulses is explained using the nonlinear density matrix equations describing the system, and is attributed to the real part of the parameter emerging from the interaction between excitons in the quantum dot and plasmons in the metal nanoparticle. The simplicity of the conventional chirped pulses, which can also be easily implemented in the laboratory, make the proposed robust quantum control scheme potentially useful for the implementation of ultrafast nanoswitches and quantum information processing tasks with semiconductor quantum dots.

description: The crisis of the formalistic legal conceptions of the late twentieth century led to a reconsideration of the issues related to the correlation among law, morality and politics. One of such issues was the re-evaluation, in practical-argumentative terms, of the concept of rationality embedded in the Constitution. Before providing a critical overview of the core aspects and the key theories of the literature conducted in this direction, this dissertation will focus on the concept of ‘argumentation’ in general terms and, subsequently, will address its applicability in legal terms. ..

description: Con la crisi delle concezioni formalistiche del diritto negli ultimi decenni del Novecento, si assiste ad un ripensamento di tutte le questioni legate al rapporto diritto/morale/politica a partire dalla rivalutazione in chiave pratico-argomentativa della razionalità implicita nella Costituzione. Prima di passare alla disamina delle maggiori peculiarità della teoria dell’ argomentazione giuridica e all’analisi critica delle teorie dei suoi più importanti esponenti mettendone in evidenza luci ed ombre, per un’ approfondita ricostruzione del dibattito teorico, è opportuno porre l’accento su cosa sia l’argomentazione in generale, per poi focalizzarci sulle specificità dell’argomentazione giuridica, analizzandone le varie concezioni. ..
