description: A paucity of research investigating men as a group has been in observed in the psychological literature, and researchers have further highlighted the need for psychologists to better understand and attend to men’s mental health needs. This study explored the help-seeking experiences of male victims of female-perpetrated domestic abuse. Patterns observed in the literature on men’s help-seeking behaviour have uncovered consistent under-utilisation of mental health resources, as well as the presence of gender role and masculinity-related issues in how mental health issues are perceived and responded to. Various internal and external barriers to help-seeking in male victims of female-perpetrated domestic abuse have also been observed. Review of the relevant theory and literature produced a rationale for exploring male domestic abuse victims using an indepth, qualitative approach. This UK-based study investigated the help-seeking experiences of eight research participants via semi-structured interviews. The resultant data were analysed using Interpretative Phenomenological Analysis (IPA), and produced five superordinate themes: ‘Blind spots’; ‘Reasons for pause’; ‘Vulnerability’; ‘Invalidation’; and ‘Finding help’. Findings were considered in the context of psychological theory and the current literature, with a focus on aspects of invisibility, masculinity and female privilege. The findings suggest that gender role-related tensions may be a salient issue in helpseeking for men abused by women, that representation of abused men in domestic abuse discourse needs to be increased, and that aspects of female privilege may be used against male victims by female abusers, which can have a detrimental impact on victims’ ability to access help. Clinical implications are discussed, which include the need to challenge stereotypes about domestic abuse, develop gender-informed interventions and harnessing positive aspects of masculinity in designing mental health interventions.

description: In this paper, we prove two supercongruences by the Wilf-Zeilberger method. One of them is, for any prime $p>3$, \begin{align*} \sum_{n=0}^{(p-1)/2}\frac{3n+1}{(-8)^n}\binom{2n}n^3\equiv p\left(\frac{-1}p\right)+\frac{p^3}4\left(\frac2p\right)E_{p-3}\left(\frac14\right)\pmod{p^4}, \end{align*} where $\left(\frac{\cdot}p\right)$ stands for the Legendre symbol, and $E_{n}(x)$ are the Euler polynomials. This congruence confirms a conjecture of Sun \cite[(2.18)]{sun-numb-2019} with $n=1$.

description: The paper analyze some general aspects about innovation process in the economic reality. The authors emphasize the benefits of innovation (built the infrastructure all over the world; changed the world from an agrarian society to an industrial society; overspecialized some professions and erases some professions etc.) and the main four factors which have a great influence over the innovation process (process, resources, infrastructure and culture). Another important aspect is the correlation between innovation and economic growth.
The effect of viscous relaxation on the spatiotemporal stability of capillary jets
Creators: name: Sevilla, Alejandro
Publisher: name: arXiv
Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The linear spatiotemporal stability properties of axisymmetric laminar capillary jets with fully developed initial velocity profiles are studied for large values of both the Reynolds number, $Re=Q/(π\,a\,ν)$, and the Froude number, $Fr=Q^2/(π^2\,g\,a^5)$, where $a$ is the injector radius, $Q$ the volume flow rate, $ν$ its kinematic viscosity, and $g$ the gravitational acceleration. The downstream development of the basic flow and its stability are addressed with an approximate formulation that takes advantage of the jet slenderness. The base flow is seen to depend on two parameters, namely a Stokes number, $G=Re/Fr$, and a Weber number, $We=ρ\,Q^2/(π^2\,σ\,a^3)$, where $σ$ is the surface tension coefficient, while its linear stability depends also on the Reynolds number. When non-parallel terms are retained in the local stability problem, the analysis predicts a critical value of the Weber number, $We_c(G,Re)$, below which a pocket of local absolute instability exists within the near field of the jet. The function $We_c(Re)$ is computed for the buoyancy-free jet, showing marked differences with the results previously obtained with uniform velocity profiles. It is seen that, in accounting for gravity effects, it is more convenient to express the parametric dependence of the critical Weber number with use made of the Morton and Bond numbers, $Mo=ν^4 ρ^3 g/σ^3$ and $Bo=ρg a^2/σ$, as replacements for $G$ and $Re$. This alternative formulation is advantageous to describe jets of a given liquid for a known value of $g$, in that the resulting Morton number becomes constant, thereby leaving $Bo$ as the only relevant parameter. The computed function $We_c(Bo)$ for a water jet under Earth gravity is shown to be consistent with the experimental results of Clanet \& Lasheras (J. Fluid Mech. vol. 383, 1999, p. 307).

title: Computational analysis of the Caenorhabditis elegans genome sequence.
Creators: name: Jones, Steven John Mathias
Publisher: name: The Open University
Year: 1999

description: The genomic sequencing of the model genetic organism, the nematode Caenorhabditis elegans is now essentially complete, representing the first genome sequence to be derived for a multicellular organism. This thesis describes the strategies and software tools that have been utilized in the analysis of the genomic sequence: Preliminary analysis of genomic organisation is also presented.
 C. elegans chromosomes do not store genetic information in a uniform manner. Gene density varies between different chromosomal regions and between chromosomes. The highly recombinagenic autosomal arms possess more repetitive elements and generally have a lower gene density than the recombinationally suppressed central regions. Although, the gene density within autosomal arms is higher than had been previously expected. A positive correlation is observed between the number of genetically defined loci from a chromosomal region and the expression rate of a region as estimated by the abundance of Expressed Sequence Tags (ESTs). A similar positive correlation is observed with the proportion of genes possessing similarity to rion-nematoda proteins. Chromosomal regions with a high density of gene clusters have fewer genetically derived loci. Demonstrating that redundancy reduces the genetic accessibility of a region towards classical genetic approaches.
Introns are larger on the autosomal arms than the central clusters. Exon length shows no correlation with chromosomal position but increases with expression rate. Stop codon preference is also influenced by expression rate.
 Clusters of similar genes are also found on the C. elegans chromosomes although their distribution is not random. The majority of gene clusters have been determined to lie on chromosome V and the left arm of II. The orientation of the genes within gene clusters suggests that inversion events are common and provide a selective advantage. Alternative splicing has also been studied and the results suggest that many alternative transcripts can be attributed to errors in splice acceptor processing.
Spin dependent quantum transport effects in Cu nanowires

description: In this work we investigate quantum transport in Cu nanowires created by bringing macroscopic Cu wires into and out of contact under an applied magnetic field in air. Here we show that a 70 % magneto-conductance effect can be seen in a Cu nanowire in a field of 2 mT at room temperature. We propose that this phenomenon is a consequence of spin filtering due to the adsorption of atmospheric oxygen modifying the electronic band structure and introducing spin split conduction channels. This is a remarkable result since bulk Cu is not magnetic and it may provide a new perspective in the quest for spintronic devices.

description: Neoclassical comprehension of economic development, based on the models of economic growth, represents powerfull theoretical framework. However,mechanistic views that dominate this approach are the source of some theoretical constrains. In the paper major elements are scatched of those theories, that analyze economic development as the interplay of different evolutionary mechanisms. Evolutionary concepts of economic development can have significant contribution to traditional development economics. Furthermore,evolutionary approach must be incorporated into the modern paradigm of economic development.
Disturbance Preview for Nonlinear Model Predictive Trajectory Tracking of Underwater Vehicles in Wave Dominated Environments

description: Operating in the near-vicinity of marine energy devices poses significant challenges to the control of underwater vehicles, predominantly due to the presence of large magnitude wave disturbances causing hazardous state perturbations. Approaches to tackle this problem have varied, but one promising solution is to adopt predictive control methods. Given the predictable nature of ocean waves, the potential exists to incorporate disturbance estimations directly within the plant model; this requires inclusion of a wave predictor to provide online preview information. To this end, this paper presents a Nonlinear Model Predictive Controller with an integrated Deterministic Sea Wave Predictor for trajectory tracking of underwater vehicles. State information is obtained through an Extended Kalman Filter, forming a complete closed-loop strategy and facilitating online wave load estimations. The strategy is compared to a similar feed-forward disturbance mitigation scheme, showing mean performance improvements of 51% in positional error and 44.5% in attitude error. The preliminary results presented here provide strong evidence of the proposed method's high potential to effectively mitigate disturbances, facilitating accurate tracking performance even in the presence of high wave loading.

description: In this text we combine the notions of supergeometry and supersymmetry. We construct a special class of supermanifolds whose reduced manifolds are (pseudo) Riemannian manifolds. These supermanifolds allow us to treat vector fields on the one hand and spinor fields on the other hand as equivalent geometric objects. This is the starting point of our definition of {supersymmetric Killing structures}. The latter combines subspaces of vector fields and spinor fields, provided they fulfill certain field equations. This naturally leads to a superalgebra that extends the supersymmetry algebra to the case of non-flat reduced space. We examine in detail the additional terms that enter into this structure and we give a lot of examples.

description: Achieving a particular response to serve multiple wireless
applications is regarded as the primary demand in our
modern age because of the considerable development of the
communication devices. In this paper, a compact monopole
antenna with reduced ground plane has been suggested to
meet the requirements of the dual-band WLAN applications. The antenna miniaturization has been carried out in employing two techniques. Initially, the fractal geometry has been applied to the antenna radiating element. Two-sided Koch fractal curves up to the third iteration have been used to increase the path of electrical current on the surface of the radiating element which is in the form of a square with dimensions. To gain more miniaturization, the antenna ground plane has been further reduced by using different lengths of two open-ended parallel stubs to form a virtually extended ground plane. This supportive technique has been adopted as a tuning means to control the path of the electrical currents exciting the resulting resonances. The
proposed antenna and has been printed on an FR-4 substrate with a thickness of 1.6 mm and 4.4 relative dielectric constant and is fed by 50-ohm microstrip feed line. The resulting antenna dimensions are of about 18.93 mm ×
18.93 mm. A parametric study has been carried out, and the
results reveal that the proposed antenna offers a dual-band
performance with a considerable ratio of resonant frequencies covering the existing 2.4/5.8 GHz WLAN
applications, besides many other communication services.
Measured results of a fabricated prototype show the validity
of the proposed methodology to design a compact size dual-band antenna.
On the Application of the Gallavotti-Cohen Fluctuation Relation to Thermostatted Steady States Near Equilibrium

description: The fluctuation relation of the Gallavotti-Cohen Fluctuation Theorem (GCFT) concerns fluctuations in the phase space compression rate of dissipative, reversible dynamical systems. It has been proven for Anosov systems, but it is expected to apply more generally. This raises the question of which non-Anosov systems satisfy the fluctuation relation. We analyze time dependent fluctuations in the phase space compression rate of a class of N-particle systems that are at equilibrium or in near equilibrium steady states. This class does not include Anosov systems or isoenergetic systems, however, it includes most steady state systems considered in molecular dynamics simulations of realistic systems. We argue that the fluctuations of the phase space compression rate of these systems at or near equilibrium do not satisfy the fluctuation relation of the GCFT, although the discrepancies become somewhat smaller as the systems move further from equilibrium. In contrast, similar fluctuation relations for an appropriately defined dissipation function appear to hold both near and far from equilibrium.

description: We propose a mechanism to achieve the group velocity control of bifurcation light via an imaginary coupling effect in the non-reciprocal lattice. The physical model is composed of two-layer photonic lattices with non-reciprocal coupling in each unit cell, which can support a real energy spectrum with a pair of Dirac points in the first Brillouin zone due to the Hermicity. Furthermore, we show that the systems experience topological phase transition at the Dirac points by tuning the coupling strength, allowing the existence of topological edge states on the left or right boundaries of respective lattice layers. By adjusting the imaginary coupling and the wave number, the group velocity of the light wave can be manipulated, and bifurcation light transmission can be achieved both at the Dirac points and the condition without the group velocity dispersion. Our work might guide the design of photonic directional couplers with group velocity control functions.

description: In this work, we investigate the semileptonic decays of $B_{c}$ meson to $η_{c}(1S,2S,3S)$, $ψ(1S,2S,3S)$ and $X(3872)$ within the framework of covariant light-front quark model (CLFQM). We combine the helicity amplitudes via the corresponding form factors to obtain the branching ratios of the semileptonic decays $B_{c}\to η_{c}(1S, 2S, 3S)\ellν_{\ell}$, $B_{c}\to ψ(1S, 2S, 3S))\ellν_{\ell}$ and $B_{c}\to X(3872)\ellν_{\ell}$ with $\ell=e,μ,τ$. In view of the $R_{J/Ψ}$ anomaly released by the LHCb collaboration, it is necessary to calculate the ratios $R_X$ with $X=ψ(1S,2S,3S),η_c(1S,2S,3S),X(3872)$ systematically, which are helpful to check the lepton flavor universality (LFU). Furthermore, we also take into account another two physical observables, one is the longitudinal polarization fraction $f_{L}$ and the other is the forward-backward asymmetry $A_{FB}$, which can provide new clues to understand the $R_{J /Ψ}$ anomaly. Such theoretical predictions are necessary and interesting, which can be tested in the future LHCb experiments.

Entropy growth of shift-invariant states on a quantum spin chain

description: We study the entropy of pure shift-invariant states on a quantum spin chain. Unlike the classical case, the local restrictions to intervals of length $N$ are typically mixed and have therefore a non-zero entropy $S_N$ which is, moreover, monotonically increasing in $N$. We are interested in the asymptotics of the total entropy. We investigate in detail a class of states derived from quasi-free states on a CAR algebra. These are characterised by a measurable subset of the unit interval. As the entropy density is known to vanishes, $S_N$ is sublinear in $N$. For states corresponding to unions of finitely many intervals, $S_N$ is shown to grow slower than $(\log N)^2$. Numerical calculations suggest a $\log N$ behaviour. For the case with infinitely many intervals, we present a class of states for which the entropy $S_N$ increases as $N^α$ where $α$ can take any value in $(0,1)$.

description: Centers of starburst galaxies may be characterized by a specific gas and ice chemistry due to their gas dynamics and the presence of various ice desorption mechanisms. This may result in a peculiar observable composition. We analyze abundances of $CO_2$, a reliable tracer of ice chemistry, from data collected as part of the ALMA large program ALCHEMI, a wide-frequency spectral scan toward the starburst galaxy NGC~253 with an angular resolution of 1.6$''$. We constrain the $CO_2$ abundances in the gas phase using its protonated form $HOCO^+$. The distribution of $HOCO^+$ is similar to that of methanol, which suggests that $HOCO^+$ is indeed produced from the protonation of $CO_2$ sublimated from ice. The $HOCO^+$ fractional abundances are found to be $(1-2)\times10^{-9}$ at the outer part of the central molecular zone (CMZ), while they are lower ($\sim10^{-10}$) near the kinematic center. This peak fractional abundance at the outer CMZ is comparable to that in the Milky Way CMZ, and orders of magnitude higher than that in Galactic disk star-forming regions. From the range of $HOCO^+/CO_2$ ratios suggested from chemical models, the gas-phase $CO_2$ fractional abundance is estimated to be $(1-20)\times10^{-7}$ at the outer CMZ, and orders of magnitude lower near the center. We estimate the $CO_2$ ice fractional abundances at the outer CMZ to be $(2-5)\times10^{-6}$ from the literature. A comparison between the ice and gas $CO_2$ abundances suggests an efficient sublimation mechanism. This sublimation is attributed to large-scale shocks at the orbital intersections of the bar and CMZ.

description: We investigate numerically the transverse and longitudinal correlation lengths of the three-dimensional O(4) model as a function of the external field H. In the low-temperature phase we verify explicitly the H^{-1/2}-dependence of the transverse correlation length, which is expected due to the Goldstone modes of the model. On the critical line we find the universal amplitude ratio xi^c_T / xi^c_L = 1.99(1). From our data we derive the universal scaling function for the transverse correlation length. The H-dependencies of the correlation lengths in the high temperature phase are discussed and shown to be in accord with the scaling functions.

Analysis of student satisfaction and life experience indicators

Publisher: name: The University of British Columbia

description: International students provide a broad range of benefits to the global economy, their home country, their host country, and the institutions that are privileged to serve as their hosts. However, studies have found that Canada is lagging behind other Anglo-Western nations, such as Great Britain, the USA and Australia, in attracting students from abroad. Using a subset of data from a study conducted jointly by the University of British Columbia, York University, McGill University, and Dalhousie University this paper undertakes to analyze the experience of international students at those institutions. With a view to developing a preliminary understanding of how Canadian domestic and international students vary in their academic experiences, different areas of those experiences have been explored. For female international respondents, the mean level of satisfaction with academic programs and course instructors was significantly lower than their domestic counterparts, and compared to their domestic counterparts international male respondents reported significantly less satisfaction with their course instructors. Also, I found that the determinants of satisfaction with academic programs and instructors varied between domestic and international students. When gender is introduced as a variable, results indicate that both male and female international students are less satisfied with their instructors, academic programs, and staff contacts than their domestic counterparts. The results also indicate that the determinants of satisfaction differ for male and female international students differ, and from their domestic counterparts. The fact that the differences between domestic male and female students are not mirrored in the results for international male and female participants raises a concern about whether the questions posed in the survey instrument are valid across cultures.

description: We show that the supersymmetry transformations for type II string theories on six-manifolds can be written as differential conditions on a pair of pure spinors, the exponentiated Kahler form exp(iJ) and the holomorphic form Omega. The equations are explicitly symmetric under exchange of the two pure spinors and a choice of even or odd-rank RR field. This is mirror symmetry for manifolds with torsion. Moreover, RR fluxes affect only one of the two equations: exp(iJ) is closed under the action of the twisted exterior derivative in IIA theory, and similarly Omega is closed in IIB. Modulo a different action of the B-field, this means that supersymmetric SU(3)-structure manifolds are all generalized Calabi-Yau manifolds, as defined by Hitchin. An equivalent, and somewhat more conventional, description is given as a set of relations between the components of intrinsic torsions modified by the NS flux and the Clifford products of RR fluxes with pure spinors, allowing for a classification of type II supersymmetric vacua on six-manifolds. We find in particular that supersymmetric six-manifolds are always complex for IIB backgrounds while they are twisted symplectic for IIA.

description: We provide elementary and uniform proofs of order independence for various strategy elimination procedures for finite strategic games, both for dominance by pure and by mixed strategies. The proofs follow the same pattern and focus on the structural properties of the dominance relations. They rely on Newman's Lemma established in 1942 and related results on the abstract reduction systems.

description: Model-independent measurements for the cosmic spatial curvature, which is related to the nature of cosmic space-time geometry, plays an important role in cosmology. On the basis of the Distance Sum Rule in the Friedmann-Lema{î}tre-Robertson-Walker metric, (distance ratio) measurements of strong gravitational lensing (SGL) systems together with distances from type Ia supernovae observations have been proposed to directly estimate the spatial curvature without any assumptions for the theories of gravity and contents of the universe. However, previous studies indicated that a spatially closed universe was strongly preferred. In this paper, we re-estimate the cosmic curvature with the latest SGL data which includes 163 well-measured systems. In addition, possible factors, e.g. combination of SGL data from different surveys and stellar mass of the lens galaxy, which might affect estimations for the spatial curvature, are considered in our analysis. We find that, except the case where only SGL systems from the Sloan Lens ACS Survey are considered, a spatially flat universe is consistently favored at very high confidence level by the latest observations. It is suggested that the increasing number of well-measured strong lensing events might significantly reduce the bias of estimation for the cosmic curvature.

description: Fractal geometries are attractive for antenna designers seeking antennas with compact size and multiband resonant behavior. This paper presents the design of a new microstrip-fed printed slot antenna for use in dual-band wireless applications. The slot structure of the proposed antenna is in the form of Cantor square fractal geometry of the second iteration. The slot structure has been etched on the ground plane of a substrate with relative permittivity of 4.4 and 1.6 mm in thickness. A parametric study is conducted to explore the effects of some geometrical parameters on the antenna performance. Results show that the antenna possesses a dual-band behavior with a wide range of resonant frequency ratio. In addition to the ease of fabrication and simple design procedure, the antenna offers desirable radiation characteristics. A prototype of the proposed antenna has been simulated, fabricated, and measured. The measured 10 dB return loss bandwidths for the lower and the upper resonant bands are 42% (2.35–3.61 GHz) and 20% (5.15–6.25 GHz), respectively. This makes the proposed antenna suitable to cover a number of operating bands of wireless systems (2.4 GHz-Bluetooth, 2.4 GHz ISM, 2.4/5.8 GHz-WLAN, 3.5 GHz-WiMAX, and 5.8 GHz-ITS).

description: The magnetic field governs the corona; hence it is a crucial parameter to measure. Unfortunately, existing techniques for estimating its strength are limited by strong assumptions and limitations. These techniques include photospheric or chromospheric field extrapolation using potential or non-linear-force-free methods, estimates based on coronal seismology, or by direct observations via, e.g., the Cryo-NIRSP instrument on DKIST which will measure the coronal magnetic field, but only off the limb. Alternately, in this work we investigate a recently developed approach based on the magnetic-field-induced (MIT) transition of the \fex~257.261~Å. In order to examine this approach, we have synthesized several \fex\ lines from two 3D magnetohydrodynamic simulations, one modeling an emerging flux region and the second an established mature active region. In addition, we take bound-free absorption from neutral hydrogen and helium and singly ionised helium into account. The absorption from cool plasma that occurs at coronal heights has a significant impact on determining the magnetic field. We investigate in detail the challenges of using these \fex\ lines to measure the field, considering their density and temperature dependence. We present a novel approach to deriving the magnetic field from the MIT using inversions of the differential emission measure as a function of the temperature, density, and magnetic field. This approach successfully estimates the magnetic field strength (up to \%18 relative error) in regions that do not suffer from significant absorption and that have relatively strong coronal magnetic fields ($>250$~G). This method allows the masking of regions where absorption is significant.

description: Quantum technologies have the potential to solve certain computationally hard problems with polynomial or super-polynomial speedups when compared to classical methods. Unfortunately, the unstable nature of quantum information makes it prone to errors. For this reason, quantum error correction is an invaluable tool to make quantum information reliable and enable the ultimate goal of fault-tolerant quantum computing. Surface codes currently stand as the most promising candidates to build near term error corrected qubits given their two-dimensional architecture, the requirement of only local operations, and high tolerance to quantum noise. Decoding algorithms are an integral component of any error correction scheme, as they are tasked with producing accurate estimates of the errors that affect quantum information, so that they can subsequently be corrected. A critical aspect of decoding algorithms is their speed, since the quantum state will suffer additional errors with the passage of time. This poses a connundrum, where decoding performance is improved at the expense of complexity and viceversa. In this review, a thorough discussion of state-of-the-art decoding algorithms for surface codes is provided. The target audience of this work are both readers with an introductory understanding of the field as well as those seeking to further their knowledge of the decoding paradigm of surface codes. We describe the core principles of these decoding methods as well as existing variants that show promise for improved results. In addition, both the decoding performance, in terms of error correction capability, and decoding complexity, are compared. A review of the existing software tools regarding surface codes decoding is also provided.

description: The prime purpose of competition policy is to promote and maintain a process of effective competition so as to achieve a more efficient allocation of resources. The improvement of competition regime is necessary for ensuring competitiveness of goods and services. The purpose and aims of competition policy (giving in the competition law) are general protection of competition, anti-collusion, anti-monopoly and merger control, conduct of public agents (including firms enjoying exclusive rights). Competition policy also depends on the pro-competitive nature of other parts of economic policy (for example, trade policy).
