description: We develop a pairing-field formalism for ab initio studies of non-relativistic two-component fermions on a $(d\!+\!1)$-dimensional spacetime lattice. More specifically, we focus on theories where the interaction between the two components can be described by the exchange of a corresponding pairing field. The introduction of a pairing field may indeed be convenient for studies of, e.g., the finite-temperature phase structure and critical behavior of, e.g., ultracold atomic Fermi gases. Moreover, such a formalism allows to directly compute the momentum and frequency dependence of the pair propagator, from which the pair-correlation function can be extracted. For a first illustration of the application of our formalism, we compute the density equation of state and the superfluid order parameter for a gas of unpolarized fermions in $(0\!+\!1)$ dimensions by employing the complex Langevin approach to surmount the sign problem.

description: Background: Menopause is the universal physiological process of women’s midlife and exhibits a wide variety of symptoms. However, there is little data on the menopausal symptoms and factors associated with their severity among rural Indian women. Aim: To evaluate the prevalence of menopausal symptoms during the different transition phases of menopause among rural women of North India. Subjects and methods: This cross-sectional study consisted of 351 women aged 35–55 years (mean age 44.6 years) residing in rural areas of North India. A structured questionnaire was used to collect data regarding menopausal status, demographic profile and reproductive history of the participants. Frequency and severity of menopausal symptoms were evaluated using the Greene Climacteric Scale in different stages of menopause. All statistical procedures were accomplished using SPSS version 19.0. Results: In the present study the mean ages of attainment of menarche and menopause were 14.3 years and 47.2 years, respectively. Mean score of total Greene Climacteric Scale was highest among perimenopausal women (16.12 ± 8.1) over post-menopausal (14.78 ± 7.3) and pre-menopausal women (11.08 ± 6.1). Logistic regression analysis revealed that advancing age, low educational attainment, low socioeconomic status, menopausal status, later age at menarche and higher BMI were all associated with more severe menopausal symptoms. Conclusion: The climacteric symptoms were more prevalent among women who were perimenopausal followed by post-menopausal women and were the lowest in pre-menopausal women. Age, menopausal status, socio-economic status, and reproductive factors significantly influenced the severity of menopausal symptoms.

description: As a first result we prove higher order Schauder estimates for solutions to singular/degenerate elliptic equations of type: \[ -\mathrm{div}\left(ρ^aA\nabla w\right)=ρ^af+\mathrm{div}\left(ρ^aF\right) \quad\textrm{in}\; Ω\] for exponents $a>-1$, where the weight $ρ$ vanishes in a non degenerate manner on a regular hypersurface $Γ$ which can be either a part of the boundary of $Ω$ or mostly contained in its interior. As an application, we extend such estimates to the ratio $v/u$ of two solutions to a second order elliptic equation in divergence form when the zero set of $v$ includes the zero set of $u$ which is not singular in the domain (in this case $ρ=u$, $a=2$ and $w=v/u$). We prove first $C^{k,α}$-regularity of the ratio from one side of the regular part of the nodal set of $u$ in the spirit of the higher order boundary Harnack principle established by De Silva and Savin. Then, by a gluing Lemma, the estimates extend across the regular part of the nodal set. Finally, using conformal mapping in dimension $n=2$, we provide local gradient estimates for the ratio which hold also across the singular set.

description: Dimer C60 solids are monoclinic crystals with molecular longer axis aligned along the c-axis. A simple model based on atom-atom potential used to calculate various bulk, structural and thermodynamic properties of this fullerite, has also been used to investigate the pressure and temperature dependent properties such as bulk modulus, lattice and orientational structure, phonon dispersion relations, Gruneisen parameters, heat capacity and entropy. An important feature of this solid evidently concerns its anisotropic pressure compression. We calculate these directional compressibilities and find the anisotropy for pressure compression very significant. It is expected that the properties of dimer solid C60 calculated here will motivate further experimentation on this solid.

description: Background: Cancer-related cognitive impairment (CRCI) is a commonly reported complaint among non-CNS cancer patients. Even subtle CRCI may have detrimental effects on quality of life and identifying patients at increased risk for CRCI to improve survivorship care is important. In the present paper, we systematically reviewed available studies of possible genetic risk factors for developing CRCI. Methods: Keyword-based systematic searches were undertaken on 24 July 2018 in PubMed, Web of Science, The Cochrane Library, and CINAHL. Three authors independently evaluated full-texts of identified papers and excluded studies with registration of reasons. Seventeen studies reporting results from 14 independent samples were included for review. Two authors independently quality assessed the included studies. The review was preregistered with PROSPERO (CRD42018107689). Results: Ten studies investigated apolipoprotein E (APOE), with four studies reporting that carrying at least one risk allele (APOE4 (ε4)) was associated with CRCI, while six studies found no association. The remaining identified genetic risk variants associated with CRCI located in: COMT, four DNA repair genes, five oxidative stress genes, 22 genes related to breast cancer phenotype, and GNB3. No associations were found between CRCI and genes coding for interleukin-6 (IL6), tumor necrosis factor alpha (TNF), interleukin 1 beta (IL1B), and brain-derived neurotropic factor (BDNF). With the exception of APOE, the genetic risk factors had only been investigated in one or two studies each. Conclusions: Overall, the available evidence of possible genetic risk factors for CRCI is limited. While some research suggests a role for the ε4 allele, the literature is generally inconsistent, and the currently available evidence does not allow clear-cut conclusions regarding the role of genetic factors in the development of CRCI. Larger genetic studies and studies investigating additional genetic variants are needed to uncover genetic risk factors for CRCI.

description: Genus Synsyllidia Uchida, gen. nov
 Synsyllidia Uchida, 2004: 32 (nomen nudum, without type species fixation); Ruta et al. 2006: 101.
 Diagnosis. Prostomium rectangular, with two antennae and bi-articulated palps. Without facial tubercle. Proboscis with distal ring of papillae, without jaws. Three apodous tentacular segments bearing six pairs of cirri with distinct cirrophores. Neuropodia subconical, without extra lobes. Each neuropodium with single acicular simple chaeta and several compound heterogomph falcigers. Some anterior segments without simple chaetae.
 Type species. Synsyllidia alternata sp. nov., fixed by original designation.
 Gender. Feminine.
 Etymology. The genus is named after the resemblance to Syllidia Quatrefages, 1865.
 Remarks. Seven known genera of hesionids have six pairs of tentacular cirri and papillae on the outer rim of the proboscis: Microphthalmus Mecznikow, 1865, Micropodarke Okuda, 1938; Neopodarke Hartman, 1965; Heteropodarke Hartmann-Schröder, 1962; Parahesione Pettibone, 1956; Nereimyra Blainville, 1828; and Syllidia. The last two have horny jaws or horny ridges in proboscis, while palps are simple in Microphthalmus, Heteropodarke, and Parahesione. Neopodarke has clearly uniramous parapodia, without notopodial acicula. Synsyllidia is closely related to Micropodarke. Both genera have two antennae, two bi-articulated palps, six pairs of articulated tentacular cirri, and sub-biramous parapodia. However, Synsyllidia possesses simple subconical parapodia, and acicular chaetae, whereas Micropodarke has conspicuous parapodial lobes and lacks acicular chaetae.

description: I provide numerical evidence for the robustness of the Griffiths phase (GP) reported previously in dynamical threshold model simulations on a large human brain network with N=836733 connected nodes. The model, with equalized network sensitivity, is extended in two ways: introduction of refractory states or by randomized time dependent thresholds. The non-universal power-law dynamics in an extended control parameter region survives these modifications for a short refractory state and weak disorder. In case of temporal disorder the GP shrinks and for stronger heterogeneity disappears, leaving behind a mean-field type of critical transition. Activity avalanche size distributions below the critical point decay faster than in the original model, but the addition of inhibitory interactions sets it back to the range of experimental values.

description: The use of calcium solutions is a cost-limiting factor for bio-cement production from microbially induced carbonate precipitation (MICP). The aim of this article is to analyse the feasibility of using recycled calcium sources to solidify sand, including oyster shells, scallop shells and eggshells, by comparing the physical and mechanical properties and microstructural characteristics of solidified sand with different recycled calcium sources and chemical calcium nitrate. The results show that oyster shells have the optimal effect on MICP, with values of permeability, dry density, unconfined compressive strength and calcium carbonate precipitation of 1.12 × 10−4 m s−1, 2.09 g cm−3, 1454.6 kPa and 15.28%, respectively. Strength values of bio-cemented sands made from different recycled calcium sources in this article range from 845.1 to 1454.6 kPa. According to the SEM and XRD analysis, calcium carbonates originating from the above recycled calcium sources precipitate as globular vaterite, whereas the precipitation from calcium nitrate is a cluster mixture of vaterite and calcite. Oyster shells, scallop shells and eggshells derived from kitchen waste, which is more economical and environmentally friendly than calcium nitrate, can be applied as recycled calcium solutions in MICP.

description: To improve the spatial resolution of power Doppler (PD) imaging, we explored null subtraction imaging (NSI) as an alternative beamforming technique to delay-and-sum (DAS). NSI is a nonlinear beamforming approach that uses three different apodizations on receive and incoherently sums the beamformed envelopes. NSI uses a null in the beam pattern to improve the lateral resolution, which we apply here for improving PD spatial resolution both with and without contrast microbubbles. In this study, we used NSI with three types of singular value decomposition (SVD)-based clutter filters and noise equalization to generate high-resolution PD images. An element sensitivity correction scheme was also proposed as a crucial component of NSI-based PD imaging. First, a microbubble trace experiment was performed to evaluate the resolution improvement of NSI-based PD over traditional DAS-based PD. Then, both contrast-enhanced and contrast free ultrasound PD images were generated from the scan of a rat brain. The cross-sectional profile of the microbubble traces and microvessels were plotted. FWHM was also estimated to provide a quantitative metric. Furthermore, iso-frequency curves were calculated to provide a resolution evaluation metric over the global field of view. Up to six-fold resolution improvement was demonstrated by the FWHM estimate and four-fold resolution improvement was demonstrated by the iso-frequency curve from the NSI-based PD microvessel images compared to microvessel images generated by traditional DAS-based beamforming. A resolvability of 39 um was measured from the NSI-based PD microvessel image. The computational cost of NSI-based PD was only increased by 40 percent over the DAS-based PD.

description: We show that bipolaron formation leads to a d-wave Bose-Einstein condensate in cuprates. It is the bipolaron energy dispersion rather than a particular pairing interaction which is responsible for the d-wave symmetry. The unusual low-temperature dependence of the magnetic field penetration depth in cuprates is explained by the localisation of bosons in the random potential. The temperature dependence of the penetration depth is linear with positive or negative slope depending on the random field profile.

description: We have developed a method to calculate the fundamental parameters of the vertical structure of the Galaxy in the solar neighborhood from trigonometric parallaxes alone. The method takes into account Lutz-Kelker-type biases in a self-consistent way and has been applied to a sample of O-B5 stars obtained from the Hipparcos catalog. We find that the Sun is located 24.2 +/- 1.7 (random) +/- 0.4 (systematic) pc above the galactic plane and that the disk O-B5 stellar population is distributed with a scale height of 34.2 +/- 0.8 (random) +/- 2.5 (systematic) pc and an integrated surface density of (1.62 +/- 0.04 (random) +/- 0.14 (systematic)) 10^{-3} stars pc^{-2}. A halo component is also detected in the distribution and constitutes at least ~5% of the total O-B5 population. The O-B5 stellar population within ~100 pc of the Sun has an anomalous spatial distribution, with a less-than-average number density. This local disturbance is probably associated with the expansion of Gould's belt.

description: This paper describes `Ludwig', a versatile code for the simulation of Lattice-Boltzmann (LB) models in 3-D on cubic lattices. In fact `Ludwig' is not a single code, but a set of codes that share certain common routines, such as I/O and communications. If `Ludwig' is used as intended, a variety of complex fluid models with different equilibrium free energies are simple to code, so that the user may concentrate on the physics of the problem, rather than on parallel computing issues. Thus far, `Ludwig''s main application has been to symmetric binary fluid mixtures. We first explain the philosophy and structure of `Ludwig' which is argued to be a very effective way of developing large codes for academic consortia. Next we elaborate on some parallel implementation issues such as parallel I/O, and the use of MPI to achieve full portability and good efficiency on both MPP and SMP systems. Finally, we describe how to implement generic solid boundaries, and look in detail at the particular case of a symmetric binary fluid mixture near a solid wall. We present a novel scheme for the thermodynamically consistent simulation of wetting phenomena, in the presence of static and moving solid boundaries, and check its performance.

description: The cornerstone of statistical mechanics of complex networks is the idea that the links, and not the nodes, are the effective particles of the system. Here we formulate a mapping between weighted networks and lattice gasses, making the conceptual step forward of interpreting weighted links as particles with a generalised coordinate. This leads to the definition of the grand canonical ensemble of weighted complex networks. We derive exact expressions for the partition function and thermodynamic quantities, both in the cases of global and local (i.e., node-specific) constraints on density and mean energy of particles. We further show that, when modelling real cases of networks, the binary and weighted statistics of the ensemble can be disentangled, leading to a simplified framework for a range of practical applications.

description: Bosonic encoding is an approach for quantum information processing, promising lower hardware overhead by encoding in the many levels of a harmonic oscillator mode. Scaling to multiple modes requires weak interaction for independent control, yet strong interaction for fast control. Applying fast and efficient universal control on multiple modes remains an open problem. Surprisingly, we find that displacements conditioned on the state of a single qubit ancilla coupled to multiple harmonic oscillators are sufficient for universal control. We present the conditional-no operation concept, which can be used for reducing the duration of entangling gates. Within this guiding concept, we develop the conditional not displacement control method which enables fast generation and control of bosonic states in multi-mode systems weakly coupled to a single ancilla qubit. Our method is fast despite the weak ancilla coupling. The weak coupling in turn allows for excellent separability and thus independent control. We demonstrate our control on a superconducting transmon qubit weakly coupled to a multi-mode superconducting cavity. We create both entangled and separable cat-states in different modes of the multi-mode cavity, showing entangling operations at low cross-talk while maintaining independent control of the different modes. We show that the operation time is not limited by the inverse of the coupling rate, which is the typical timescale, and we exceed it by almost 2 orders of magnitude. We verify our results with an efficient method for measurement of the multi-mode characteristic function which employs our conditional not displacement. Our results inspire a new approach toward general entangling operations and allow for fast and efficient multi-mode bosonic encoding and measurement.

 The ordinary Grothendieck construction over a small category C is a 2-equivalence that sends a C-indexed category to an opfibration over C. We show that the Grothendieck construction over a small tight bipermutative category D is a pseudo symmetric Cat-multifunctor that is generally not a Cat-multifunctor in the symmetric sense. When the projection to D is taken into account, we prove that the Grothendieck construction over D lifts to a non-symmetric Cat-multiequivalence whose codomain is a non-symmetric Cat-multicategory with small permutative opfibrations over D as objects.
 As applications we show that inverse K-theory, from Gamma-categories to small permutative categories, is a pseudo symmetric Cat-multifunctor but not a Cat-multifunctor in the symmetric sense. It follows that inverse K-theory preserves algebraic structures parametrized by non-symmetric and pseudo symmetric Cat-multifunctors but not Cat-multifunctors in general. As a special case, we observe that inverse K-theory sends pseudo symmetric E-infinity-algebras in Gamma-categories to pseudo symmetric E-infinity-algebras in small permutative categories.

description: Online communities such as Facebook and Twitter are enormously popular and have become an essential part of the daily life of many of their users. Through these platforms, users can discover and create information that others will then consume. In that context, recommending relevant information to users becomes critical for viability. However, recommendation in online communities is a challenging problem: 1) users' interests are dynamic, and 2) users are influenced by their friends. Moreover, the influencers may be context-dependent. That is, different friends may be relied upon for different topics. Modeling both signals is therefore essential for recommendations. We propose a recommender system for online communities based on a dynamic-graph-attention neural network. We model dynamic user behaviors with a recurrent neural network, and context-dependent social influence with a graph-attention neural network, which dynamically infers the influencers based on users' current interests. The whole model can be efficiently fit on large-scale data. Experimental results on several real-world data sets demonstrate the effectiveness of our proposed approach over several competitive baselines including state-of-the-art models.

description: Identifying triggers for challenging behavior is difficult in some children with autism because of their limited communication abilities. Physiological indicators of stress may provide important insights. This study examined whether heart rate (HR) predicts challenging behavior in children with autism. While wearing an electrocardiograph monitor, 41 children with autism aged 2- to 4-years participated in tasks designed to induce low-level stress (e.g. waiting for a snack). Coders identified 106 time periods during which challenging behaviors occurred and also coded 106 randomly selected time samples that did not include challenging behaviors. Thirteen (32%) participants exhibited challenging behaviors and were included in the study. Baseline-corrected HR was computed for each behavior/time sample. On average, children with autism showed a 22 ± 16% HR increase from baseline 58 ± 22 seconds before the onset of a challenging behavior episode. Peak HR change had moderate predictive utility (area under the curve = .72, p 001). The increase in HR before challenging behaviors was similar for children of different characteristics (age, autism severity, expressive language ability, overall developmental ability). Results highlight the promise of using physiological stress to predict challenging behavior in preschoolers with autism; although, they need to be replicated in larger samples. Given recent advances in wearable biosensing, it may be useful to incorporate HR monitoring in autism intervention. Lay summary In children with autism, changes in heart rate (HR) may help us predict when challenging behavior is about to occur – but this hypothesis has not been well studied. In this study, HR increase moderately predicted challenging behavior in preschoolers with autism. Given recent advances in wearable sensors, it may be useful to incorporate HR monitoring in autism intervention.

Simetria da passada

description: Resumo - Simetria é um principio físico que denota igualdade, assim, avaliar a simetria da mecânica de corrida é um passo importante para o conhecimento das condições em que o corpo trabalha durante a corrida, qual a eficiência e o possível risco de uma lesão. Esta pesquisa teve como objetivo primário, analisar a simetria do comprimento de passada dos corredores de rua e como objetivo secundário, correlacionar a possível assimetria do comprimento da passada com o lado dominante autodeclarado de membros inferiores dos voluntários. Participaram da pesquisa noventa e dois corredores do gênero masculino com média de idade: = 42,1±14,19 anos, e que correm a mais de um ano. Estes foram recrutados por meio de grupos de corrida em redes sociais e concordaram em participar da pesquisa. Inicialmente foram direcionados a responder um questionário autoavaliativo e posteriormente encaminhados para realizarem um teste com máxima intensidade de 2400 metros em uma pista de 200 metros. Em cada volta foi analisado o comprimento de dois ciclos de passada, ou seja, duas passadas com a perna direita e duas passadas com a perna esquerda. As passagens foram filmadas com uma câmera utilizando uma frequência de 60 quadros por segundos. A câmera foi posicionada a uma distância de 11,5 metros do centro da raia de corrida. As imagens foram analisadas utilizando-se o software Kinovea versão 8.27 e os procedimentos estatísticos utilizando-se uma planilha Microsoft office Excel 2007, foram aplicados testes T-Student para a análise estatística da simetria e teste de correlação de Spearman para verificar a correlação entre autodeclarados “destro” ou “canhoto” e o lado de maior comprimento de passada. Os resultados mostraram que 51,1% dos voluntários apresentavam uma passada em que a perna direita aplicava maior força no solo do que a perna esquerda, consequentemente 48,9% dos voluntários possuía a passada maior quando a perna esquerda era a que fazia a força contra o solo. Em 32,6% dos voluntários verificou-se uma assimetria menor que 1%, em 22,8 % assimetria entre 1% e 2%, em 21,7% assimetria entre 2% e 3%, em 14,1% assimetria entre 3% e 4%, e em 8,7% assimetria acima de 4%. Verificou-se também que os voluntários que tiveram a assimetria acima de 4% possuíam algum histórico de lesão no membro inferior considerado mais fraco. Como objetivo secundário foi investigado a correlação entre o lado predominante autodeclarado e o lado de maior comprimento da passada, entre estes não foi encontrado nenhuma correlação. Esta pesquisa é importante para que se faça uma investigação mais profunda para se encontrar meios de intervenção que consiga diminuir a assimetria do comprimento de passada dos corredores de rua com o intuito de prevenir lesões e melhorar a eficiência dos atletas.

description: We study the thermal behavior of correlations in a one-dimensional Bose gas with tunable interaction strength, crossing from weakly-repulsive to Tonks-Girardeau regime. A reference temperature in this system is that of the hole anomaly, observed as a peak in the specific heat and a maximum in the chemical potential. We find that at large momenta $k$ and temperature above the anomaly threshold, the tail $\mathcal{C}/k^4$ of the momentum distribution (proportional to the Tan contact $\mathcal{C}$) is screened by the $1/|k|^3$-term due to a dramatic thermal increase of the internal energy emerging from the thermal occupation of spectral excitation states. The same fading is consistently revealed in the behavior at short distances $x$ of the one-body density matrix (OBDM) where the $|x|^3$-dependence disappears for temperatures above the anomaly. We obtain a new general analytic tail for the momentum distribution and a minimum $k$ fixing its validity range, both calculated with exact Bethe-Ansatz method and valid in all interaction and thermal regimes, crossing from the quantum to the classical gas limit. Our predictions are confirmed by comparison with ab-initio Path Integral Monte Carlo calculations for the momentum distribution and the OBDM exploring a wide range of interaction strength and temperature. Our results unveil a novel connection between excitations and correlations. We expect them to be of interest to any cold atomic, nuclear, solid-state, electronic and spin system exhibiting an anomaly or a thermal second-order phase transition.

description: We derive alternate and new closed-form analytic solutions for the non-equatorial eccentric bound trajectories, $\{ ϕ\left( r, θ\right)$, $\ t \left( r, θ\right),\ r \left( θ\right) \}$, around a Kerr black hole by using the transformation $1/r=μ\left(1+ e \cos χ\right)$. The application of the solutions is straightforward and numerically fast. We obtain and implement translation relations between energy and angular momentum of the particle, ($E$, $L$), and eccentricity and inverse-latus rectum, ($e$, $μ$), for a given spin, $a$, and Carter's constant, $Q$, to write the trajectory completely in the ($e$, $μ$, $a$, $Q$) parameter space. The bound orbit conditions are obtained and implemented to select the allowed combination of parameters ($e$, $μ$, $a$, $Q$). We also derive specialized formulae for spherical and separatrix orbits. A study of the non-equatorial analog of the previously studied equatorial separatrix orbits is carried out where a homoclinic orbit asymptotes to an energetically bound spherical orbit. Such orbits simultaneously represent an eccentric orbit and an unstable spherical orbit, both of which share the same $E$ and $L$ values. We present exact expressions for $e$ and $μ$ as functions of the radius of the corresponding unstable spherical orbit, $r_s$, $a$, and $Q$, and their trajectories, for ($Q\neq0$) separatrix orbits; they are shown to reduce to the equatorial case. These formulae have applications to study the gravitational waveforms from EMRIs besides relativistic precession and phase space explorations. We obtain closed-form expressions of the fundamental frequencies of non-equatorial eccentric trajectories that are equivalent to the previously obtained quadrature forms and also numerically match with the equivalent formulae previously derived. We sketch several orbits and discuss their astrophysical applications.

description: We have used the ATNF Mopra antenna and the SEST antenna to search in the directions of several class II methanol maser sources for emission from six methanol transitions in the frequency range 85-115 GHz. The transitions were selected from excitation studies as potential maser candidates. Methanol emission at one or more frequencies was detected from five of the maser sources, as well as from Orion KL. Although the lines are weak, we find evidence of maser origin for three new lines in G345.01+1.79, and possibly one new line in G9.62+0.20. The observations, together with published maser observations at other frequencies, are compared with methanol maser modelling for G345.01+1.79 and NGC6334F. We find that the majority of observations in both sources are consistent with a warm dust (175 K) pumping model at hydrogen density ~10^6 cm^-3 and methanol column density ~5 x 10^17 cm^-2. The substantial differences between the maser spectra in the two sources can be attributed to the geometry of the maser region.

description: Directed contact networks (DCNs) are a particularly flexible and convenient class of temporal networks, useful for modeling and analyzing the transfer of discrete quantities in communications, transportation, epidemiology, etc. Transfers modeled by contacts typically underlie flows that associate multiple contacts based on their spatiotemporal relationships. To infer these flows, we introduce a simple inhomogeneous Markov model associated to a DCN and show how it can be effectively used for data reduction and anomaly detection through an example of kernel-level information transfers within a computer.
