description: We consider a magnetic superconductor MS with a spiral magnetic structure. On the basis of generalized Eilenberger and Usadel equations we show that near the boundary of the MS with an insulator or vacuum the condensate (Gor'kov's) Green's functions are disturbed by boundary conditions and differ essentially from their values in the bulk. Corrections to the bulk quasiclassical Green's functions oscillate with the period of the magnetic spiral, $2π/Q$, and decay inside the superconductor over a length of the order $v/πT$ (ballistic limit) or $\sqrt{D/πT}$ (diffusive limit). We calculate the dc Josephson current in an MS/I/MS tunnel junction and show that the critical Josephson current differs substantially from that obtained with the help of the tunnel Hamiltonian method and bulk Green's functions.

description: We use coordinate transformation theory to realize substrates that can modify the emission of an embedded source. Simulation results show that with proper transformation functions the energy radiated by a source embedded in these space variant media will be concentrated in a narrow beam. The thickness of the slab achieved with our transformations will no longer be restricted by the evanescent modes and the source can be placed at any position along the boundary of the substrate without affecting the radiation pattern. We also discuss the case where reduced parameters are used, which still performs well and is physically realizable.

description: We study the properties of the giant connected component in random graphs with arbitrary degree distribution. We concentrate on the degree-degree correlations. We show that the adjoining nodes in the giant connected component are correlated and derive analytic formulas for the joint nearest-neighbor degree probability distribution. Using those results we describe the correlations in maximal entropy connected random graphs. We show that connected graphs are disassortative and that correlations are strongly related to the presence of one-degree nodes (leaves). We propose an efficient algorithm for generating connected random graphs. We illustrate our results with several examples.

description: Objectives: Psychological well-being in people with neurological diseases can be compromised due to brain damage or psychological reactions towards chronic disabilities. This systematic review evaluated the efficacy of positive psychological intervention (PPI) in neurological populations. Methods: Previous studies relevant to this topic were identified by searches in PUBMED, EMBASE, MEDLINE, and PSYCINFO databases from Jan 1980 to August 2017. Results: Of 1361 articles identified, 31 studies were included. Nineteen studies were randomized controlled trials. Sixteen studies had sample sizes of less than 30. Twelve studies were rated as high quality using the National Heart, Lung, and Blood Institute (NHLBI) quality assessment tools. Six therapies were found: mindfulness-based approaches, positive savoring, life summary, expressive-based, hope-based interventions, and character strengths. These interventions were shown to improve quality of life, reduce symptomatic distress, and depressive symptoms. Conclusion: PPIs promote well-being among patients with neurological deficits. For PPIs to be considered as an evidence-based practice, more trials with adequate statistical power are required.
Loopy Determinations of $V_{ub}$ and $V_{cb}$

description: We use loop induced processes like meson oscillations and rare b hadron decays to determine the absolute values of the CKM matrix elements $|V_{ub}|$ and $|V_{cb}|$ and compare our results to the standard determinations based on inclusive and exclusive semileptonic tree-level decays of B mesons. For many years there have been tensions between the inclusive and exclusive determinations. Assuming the absence of new physics, we find that meson oscillation data shows a slight preference for the inclusive value of $|V_{cb}|$ and the exclusive value for $|V_{ub}|$. Rare b decay data prefers values for $|V_{cb}|$ far below the inclusive and exclusive determinations, offering a new perspective on some of the persistent rare b decay anomalies.

description: We study a totally asymmetric simple exclusion process with open boundary conditions and local resetting at the injection node. We investigate the stationary state of the model, using both mean-field approximation and kinetic Monte Carlo simulations, and identify three regimes, depending on the way the resetting rate scales with the lattice size. The most interesting regime is the intermediate resetting one, as in the case of periodic boundary conditions. In this regime we find pure phases and phase separation phenomena, including a low-density/high-density phase separation, which was not possible with periodic boundary conditions. We discuss density profiles, characterizing bulk regions and boundary layers, and nearest-neighbour covariances, finding a remarkable agreement between mean-field and simulation results. The stationary state phase diagram is mapped out analytically at the mean-field level, but we conjecture that it may be exact in the thermodynamic limit. We also briefly discuss the large resetting regime, which exhibits an inverse characteristic length scale diverging logarithmically with the lattice size.

description: The relativistic LambdaCDM cosmological model has passed a demanding network of tests that convincingly demonstrate it is a useful approximation to what happened back to high redshift. But there are anomalies in its application to structure formation on the scales of galaxies that show we have much to learn about what this theory actually predicts and possibly something also of value to learn about the fundamental theoretical basis for observational cosmology. This is slightly revised and enlarged from a contribution to A Century of Cosmology, Venice, August 2007.

description: We studied, both analytically and numerically, complex excitable networks, in which connections are time dependent and some of the nodes remain silent at each time step. More specifically, (a) there is a heterogenous distribution of connection weights and, depending on the current degree of order, some connections are reinforced/weakened with strength Phi on short-time scales, and (b) only a fraction rho of nodes are simultaneously active. The resulting dynamics has attractors which, for a range of Phi values and rho exceeding a threshold, become unstable, the instability depending critically on the value of rho. We observe that (i) the activity describes a trajectory in which the close neighborhood of some of the attractors is constantly visited, (ii) the number of attractors visited increases with rho, and (iii) the trajectory may change from regular to chaotic and vice versa as rho is, even slightly modified. Furthermore, (iv) time series show a power-law spectra under conditions in which the attractors' space is most efficiently explored. We argue on the possible qualitative relevance of this phenomenology to networks in several natural contexts.

On the insecurity of quantum Bitcoin mining

description: Grover's algorithm confers on quantum computers a quadratic advantage over classical computers for searching in an arbitrary data set, a scenario that describes Bitcoin mining. It has previously been argued that the only side-effect of quantum mining would be an increased difficulty. In this work, we argue that a crucial argument in the analysis of Bitcoin security breaks down when quantum mining is performed. Classically, a Bitcoin fork occurs rarely, i.e., when two miners find a block almost simultaneously, due to propagation time effects. The situation differs dramatically when quantum miners use Grover's algorithm, which repeatedly applies a procedure called a Grover iteration. The chances of finding a block grow quadratically with the number of Grover iterations applied. Crucially, a miner does not have to choose how many iterations to apply in advance. Suppose Alice receives Bob's new block. To maximize her revenue, she should stop and measure her state immediately in the hopes that her block (rather than Bob's) will become part of the longest chain. The strong correlation between the miners' actions and the fact that they all measure their states at the same time may lead to more forks -- which is known to be a security risk for Bitcoin. We propose a mechanism that, we conjecture, will prevent this form of quantum mining, thereby circumventing the high rate of forks.

description: The impact of formation flying on interferometry is growing over the years for the potential performance it could offer. However, it is still an open field, and many studies are still required. This article presents the basic principles behind interferometry focusing first on a single array and secondly on a formation of satellites. A sensitivity analysis is carried out to evaluate how the performance of the interferometry is affected by an error in the relative position in the formation geometry. This is estimated by computing the loss of the performance in terms of percentage deviation due to a non-nominal relative trajectory, including two-dimensional errors and defining a payload index. The main goal of this study is to estimate whether some errors in the relative state are more impacting than others. The final objective is to compute the link between a position error and a specific loss of performance, to foresee the origin of the the error. Furthermore, a dynamical model is developed to describe the relative motion in the Low Earth Orbit environment, considering both the unperturbed and the J2 and drag contributions. A Proportional, Integral and Derivative controller is implemented for the position control of a multiple satellite formation flying, considering a low thrust control profile. The Formation Flying L-band Aperture Synthesis study is taken as the case scenario, analysing both nominal and non-nominal configurations. This study serves as a starting point for the development of a combined tool to assess the performance of the interferometry and the control on the relative state for future remote sensing studies involving relative motion.

description: Noise in gene expression, either due to inherent stochasticity or to varying inter- and intracellular environment, can generate significant cell-to-cell variability of protein levels in clonal populations. We present a theoretical framework, based on stochastic processes, to quantify the different sources of gene expression noise taking cell division explicitly into account. Analytical, time-dependent solutions for the noise contributions arising from the major steps involved in protein synthesis are derived. The analysis shows that the induction level of the activator or transcription factor is crucial for the characteristic signature of the dominant source of gene expression noise and thus bridges the gap between seemingly contradictory experimental results. Furthermore, on the basis of experimentally measured cell distributions, our simulations suggest that transcription factor binding and promoter activation can be modelled independently of each other with sufficient accuracy.

description: During phylogenesis different types of immunocytes such as amoebocytes and eleocytes have developed in earthworms to defend the host against microbial pathogens. Previously we applied a cell sorting-based approach to untangle the morphological and functional properties of these aforementioned coelomocyte subsets. In order to compare their constitutive gene expression patterns, cell-sorting was performed and followed by semiquantitative RT-PCR in the distinct, separated coelomocyte subpopulations of unmanipulated Eisenia andrei earthworms. We targeted a variety of genes with diverse functions ranging from pattern recognition through intracellular signaling to oxidative stress. Several immune-related genes (CCF, TLR, lumbricin, LuRP, MyD88) were only manifested in the amoebocytes. In contrast, other immune response genes (lysozyme, lysenin), lysosomal hydrolases (cathepsin L and cathepsin C) and cystatin B were expressed in both subpopulations. In addition, cell signaling molecules (MyD88, PKC1) and oxidative stress-related genes (Cu/ZnSOD, MnSOD) were mainly observed in amoebocytes, while other stress-related genes (Cd-metallothionein, catalase) were apparent in both subsets. We conclude that these characteristic differences of the molecular signatures manifest in the functional heterogeneity of distinct coelomocyte subtypes.

description: We present ALMA 870um and JCMT SCUBA2 850um dust continuum observations of a sample of optically dark and strongly lensed galaxies in the cluster fields. The ALMA and SCUBA2 observations reach a median rms of about 0.11 mJy and 0.44 mJy, respectively, with the latter close to the confusion limit of the data at 850um. This represents one of the most sensitive searches for dust emission in optically dark galaxies. We detect the dust emission in 12 out of 15 galaxies at >3.8 sigma, corresponding to a detection rate of 80 per cent. Thanks to the gravitational lensing, our observations reach a deeper limiting flux than previous surveys in blank fields by a factor of 3. We estimate delensed infrared luminosities in the range log(LIR)=11.5-12.7 Lsun, which correspond to dust-obscured star formation rates (SFRs) of 30 to 520 Msun per year. Stellar population fits to the optical-to-NIR photometric data yield a median redshift z=4.26 and de-lensed stellar mass log(Mstar)=10.78 Msun. They contribute a lensing-corrected star-formation rate density at least an order of magnitude higher than that of equivalently massive UV-selected galaxies at z>3. The results suggest that there is a missing population of massive star-forming galaxies in the early Universe, which may dominate the SFR density at the massive end. Five optically dark galaxies are located within r<50 arcsec in one cluster field, representing a potential overdensity structure that has a physical origin at a confidence level >99.974% from Poisson statistics. Follow-up spectroscopic observations with ALMA and JWST are crucial to confirm whether it is associated with a protocluster at similar redshifts.

description: A new "on the fly" method to perform Born-Oppenheimer ab initio molecular dynamics (AIMD) is presented. Inspired by Ehrenfest dynamics in time-dependent density functional theory, the electronic orbitals are evolved by a Schroedinger-like equation, where the orbital time derivative is multiplied by a parameter. This parameter controls the time scale of the fictitious electronic motion and speeds up the calculations with respect to standard Ehrenfest dynamics. In contrast to other methods, wave function orthogonality needs not be imposed as it is automatically preserved, which is of paramount relevance for large scale AIMD simulations.

These specific fluorescent dyes make it possible to distinguish cells differing in the amount of lysosomes and in transcriptional activity. We found that hemocytes of B. glabrata were represented by hyalinocytes and granulocytes (35.34 (27.38; 36.10) and 65.13 (64.11; 73.05) % respectively). Granulocytes were generally strongly granulated and more metabolically active than hyalinocytes. This is the first report confirming the presence of these two main cell types in the hemolymph of B. glabrata with the use of specific fluorescent dyes.

description: Microsporidiosis of the silkworm Bombyx mori is caused by the highly virulent parasite Nosema bombycis (Nageli). The infection can be deleterious due to horizontal and vertical transmission, causing heavy damage to the sericulture industry. In recent years, molecular diagnostics has revolutionized the possibility to detect diseases in terms of rapidity and simplicity, however, most of them are time consuming, require sophisticated instruments and skilled personnel. In this study, the polar tube protein 1 gene of N. bombycis (Indian isolate) was cloned, characterized and utilized for the development of rapid and simple loop mediated isothermal amplification assay (LAMP) for detection of microsporidiosis in silkworm B. mori. The LAMP reaction conditions were optimized to 65 °C for 60 min. The developed method demonstrated a higher sensitivity and the detection limit was found to be 2-fold higher than conventional PCR. This is the first report on loop mediated isothermal amplification assay that could be used to diagnose microsporidiosis at various developmental stages of the silkworm. This method serves as a robust alternative technique to conventional PCR and aids in the rapid diagnosis of N. bombycis infecting silkworm B. mori.

Blind Image Deblurring Using Row-Column Sparse Representations

description: Blind image deblurring is a particularly challenging inverse problem where the blur kernel is unknown and must be estimated en route to recover the deblurred image. The problem is of strong practical relevance since many imaging devices such as cellphone cameras, must rely on deblurring algorithms to yield satisfactory image quality. Despite significant research effort, handling large motions remains an open problem. In this paper, we develop a new method called Blind Image Deblurring using Row-Column Sparsity (BD-RCS) to address this issue. Specifically, we model the outer product of kernel and image coefficients in certain transformation domains as a rank-one matrix, and recover it by solving a rank minimization problem. Our central contribution then includes solving {\em two new} optimization problems involving row and column sparsity to automatically determine blur kernel and image support sequentially. The kernel and image can then be recovered through a singular value decomposition (SVD). Experimental results on linear motion deblurring demonstrate that BD-RCS can yield better results than state of the art, particularly when the blur is caused by large motion. This is confirmed both visually and through quantitative measures.

description: Multiwavelength observations of supernova remnant (SNR) 1987A show that its morphology and luminosity are rapidly changing at X-ray, optical, infrared, and radio wavelengths as the blast wave from the explosion expands into the circumstellar equatorial ring, produced by mass loss from the progenitor star. The observed infrared (IR) radiation arises from the interaction of dust grains that formed in mass outflow with the soft X-ray emitting plasma component of the shocked gas. Spitzer IRS spectra at 5 - 30 microns taken on day 6190 since the explosion show that the emission arises from ~ 1.1E-6 Msun of silicate grains radiating at a temperature of ~180+20-15 K. Subsequent observations on day 7137 show that the IR flux had increased by a factor of 2 while maintaining an almost identical spectral shape. The observed IR-to-X-ray flux ratio (IRX) is consistent with that of a dusty plasma with standard Large Magellanic Cloud dust abundances. IRX has decreased by a factor of ~ 2 between days 6190 and 7137, providing the first direct observation of the ongoing destruction of dust in an expanding SN blast wave on dynamic time scales. Detailed models consistent with the observed dust temperature, the ionization timescale of the soft X-ray emission component, and the evolution of IRX suggest that the radiating silicate grains are immersed in a 3.5E6 K plasma with a density of (0.3-1)E4 cm^{-3}, and have a size distribution that is confined to a narrow range of radii between 0.023 and 0.22 microns. Smaller grains may have been evaporated by the initial UV flash from the supernova.

description: In the presented work, the structural, optical and thermal characteristics of GeO2-PbO-SrO-AlF3-MgF2 glasses have been investigated. In this regard, different germanate glasses containing of PbO, SrO, MgF2 and AlF3 were prepared by conventional melt quenching technique between two steel sheets. The produced samples were characterized using X-ray diffraction, differential thermal calorimetry, Fourier transform infrared and UV-Vis spectroscopy. Based on results, the glass-forming ability and thermal stability of GeO2-PbO glasses increase by replacement of PbO with SrO in glass composition. This replacement has negligible effects on optical properties of prepared glasses and the values of Eg°pt and EU of GeO2-PbO-SrO glassy system are in the range of 2.98–3.02 and 0.27–0.28 eV, respectively. In contrast, the optical properties, overall transparency, glass-forming ability and thermal stability of GeO2-PbO-SrO glasses decrease by replacement of PbO with MgF2 and AlF3.

description: Background: People who use drugs are commonly excluded from clinical research despite being disproportionately impacted by numerous health conditions. Recent work indicates that community-recruited individuals report low support of research inclusion for persons reporting substance use. Objective: This study conducted a mixed-method assessment of researchers’ attitudes on including persons reporting substance use in clinical research. Methods: Respondents (N = 168; 58% female; 58% psychologists) recruited via scientific society listservs and Twitter completed a survey containing two hypothetical research vignettes. Quantitative items evaluated respondents’ endorsement of research participation by healthy adults, people who use drugs, and vulnerable populations. Qualitative items included open-ended questions asking reasons why people who use drugs should and should not participate in research. Results: Respondents reported significantly lower support for research participation by people who use drugs compared to healthy adults (p Conclusion: Although lower support for research participation by people who use drugs was observed compared to healthy adults, the magnitude of this difference was smaller than reported for prior community-recruited respondents. These findings emphasize salient factors that may serve as both protections for and barriers to inclusion of people who use drugs in research. Initiatives including adoption of person-first language, addressing stereotyping of people who use drugs, and emphasizing the benefits of including these populations in clinical research should be explored to reduce bias while retaining needed protections.

description: We study the Oxygen and Nitrogen abundances in the interstellar medium of high-redshift galaxies. We use high resolution and high signal-to-noise ratio spectra of Damped Lyman-alpha (DLA) systems detected along the line-of-sight to quasars to derive robust abundance measurements from unsaturated metal absorption lines. We present results for a sample of 16 high-redshift DLAs and strong sub-DLAs (log N(HI)>19.5, 2.4-1 and nine systems have [N/O]

description: The $D$ and $\bar {D}$ mesons are studied in hot dense matter within a self-consistent coupled-channel approach taking, as bare interaction, a broken SU(4) s-wave Tomozawa-Weinberg interaction supplemented by an attractive isoscalar-scalar term. The in-medium solution at finite temperature incorporates Pauli blocking effects, baryon mean-field bindings, and $π$ and open-charm meson self-energies. In the $DN$ sector, the $Λ_c$ and $Σ_c$ resonances remain close to their free-space position while acquiring a remarkable width. As a result, the $D$ meson spectral density shows a single pronounced peak close to the free mass that broadens with increasing density specially towards lower energies. The low-density theorem is not a good approximation for the repulsive $\bar D$ self-energy close to saturation density. We discuss the implications for the $J/Ψ$ suppression at CBM (FAIR).

description: It was recently shown that a massive thin shell that is sandwiched between a flat interior and an exterior geometry given by the outgoing Vaidya metric becomes null in a finite proper time. We investigate this transition for a general spherically-symmetric metric outside the shell and find that it occurs generically. Once the shell is null its persistence on a null trajectory can be ensured by several mechanisms that we describe. Using the outgoing Vaidya metric as an example we show that if a dust shell acquires surface pressure on its transition to a null trajectory it can evade the Schwarzschild radius through its collapse. Alternatively, the pressureless collapse may continue if the exterior geometry acquires a more general form.

description: We provide a Lyapunov type bound in the multivariate central limit theorem for sums of independent, but not necessarily identically distributed random vectors. The error in the normal approximation is estimated for certain classes of sets, which include the class of measurable convex sets. The error bound is stated with explicit constants. The result is proved by means of Stein's method. In addition, we improve the constant in the bound of the Gaussian perimeter of convex sets.

Chiral phase transition in the presence of spinodal decomposition

description: The thermodynamics of a first order chiral phase transition is considered in the presence of spinodal phase separation within the Nambu-Jona-Lasinio (NJL) model. The properties of the basic thermodynamic observables in the coexistence phase are discussed for zero and non-zero quark masses. We focus on observables that probe the chiral phase transition. In particular, the behavior of the specific heat and entropy as well as charge fluctuations are calculated and analyzed. We show that the specific heat and charge susceptibilities diverge at the isothermal spinodal lines. We determine the scaling behavior and compute the critical exponent $γ$ of the net quark number susceptibility at the isothermal spinodal lines within the NJL model and the Ginsburg-Landau theory. We show that in the chiral limit the critical exponent $γ=1/2$ at the tricritical point as well as along the isothermal spinodal lines. On the other hand, for finite quark masses the critical exponent at the spinodal lines, $γ=1/2$, differs from that at the critical end point, $γ=2/3$, indicating a change in the universality class. These results are independent of the particular choice of the chiral Lagrangian and should be common for all mean field approaches.

description: Bombyx mori nuclear polyhedrosis virus (BmNPV) has caused great economic losses to sericulture and considerable effort has been made to identify disease resistance genes in B. mori. We constructed differential expression gene libraries of the resistant near-isogenic line (NIL) BC10 and susceptible strain 306 using the suppression subtractive hybridization technique. A total of 23 differentially expressed genes were obtained, of which 17 genes were upregulated in BC10, and 6 genes were upregulated in 306. These differentially expressed genes are involved in cell metabolism, transmembrane transport, cytoskeleton, protease, development and immunity. Six BC10 upregulated genes were verified by real-time quantitative PCR, and the results were consistent with those of subtractive hybridization. The resistance trait of NIL BC10 was inherited from the resistant strain NB, and its genetic background was 99.99% similar to that of recurrent parent 306. The upregulated genes in NIL BC10 may be associated with silkworm BmNPV resistance.

MEANS OF DEPICTING NATURE IN THE WORKS OF M.YU. LERMONTOV AND A.A. FET

description: Like any poet, Lermontov expressed in his works the era in which he lived; and the spirit of this era is reflection, doubt, deep thoughts about life without hope for the future. The consciousness of one’s exclusivity in a world where only mediocrity is blissful again and again evokes a feeling of sad loneliness. This motif, persistent in Lermontov’s lyrics, also sounds in works dedicated to nature.

Role of glutamate transporter EAAT2 in survival of silk worm Bombyx mori at higher dosages of Azaserine, an analogue of glutamine

description: Organisms are subjected to a variety of stress and physiological impact in the event of drug administration. Drug extrusion plays a critical role in the survival of organisms. The present study elucidate the role of glutamate transporter, EAAT2 in survival of model organism silkworm injected with azaserine, a glutamine analogue and offer a possible explanation for a contrasting observation of greater survival at higher dosage and lesser survival in lower dosage. Our results have shown a dosage dependent inhibition of gamma glutamyl transferase (GGT) activity, differential expression of EAAT2 transporter along with concomitant changes in residual concentration of azaserine, glutamate and cysteine that undermine cysteine transport. The current results also suggest that survival is dependent on EAAT2 transporter in cysteine-glutamate/azaserine transport and rejuvenation of ATP formation as observed in higher but not in lower dosage received worms.
