description: Aging dynamics of a reentrant ferromagnet Cu$_{0.2}$Co$_{0.8}$Cl$_{2}$-FeCl$_{3}$ graphite bi-intercalation compound has been studied using AC and DC magnetic susceptibility. This compound undergoes successive transitions at the transition temperatures $T_{c}$ ($= 9.7$ K) and $T_{RSG}$ ($= 3.5$ K). The relaxation rate $S(t)$ exhibits a characteristic peak at $t_{cr}$ close to a wait time $t_{w}$ below $T_{c}$, indicating that the aging phenomena occur in both the reentrant spin glass (RSG) phase below $T_{RSG}$ and the ferromagnetic (FM) phase between $T_{RSG}$ and $T_{c}$. The relaxation rate $S(t)$ ($=\text{d}χ_{ZFC}(t)/\text{d}\ln t$) in the FM phase exhibits two peaks around $t_{w}$ and a time much shorter than $t_{w}$ under the positive $T$-shift aging, indicating a partial rejuvenation of domains. The aging state in the FM phase is fragile against a weak magnetic-field perturbation. The time ($t$) dependence of $χ_{ZFC}(t)$ around $t \approx t_{cr}$ is well approximated by a stretched exponential relaxation: $χ_{ZFC}(t) \approx \exp[-(t/τ)^{1-n}]$. The exponent $n$ depends on $t_{w}$, $T$, and $H$. The relaxation time $τ$ ($\approx t_{cr}$) exhibits a local maximum around 5 K, reflecting a chaotic nature of the FM phase. It drastically increases with decreasing temperature below $T_{RSG}$.

description: Inspired by the newly observed $Ω_b$ states by the LHCb Collaboration, we investigate the two-body strong decays of the low-lying $λ$-mode $Ω_b$ baryons up to $N=2$ shell using the chiral quark model within the $j$-$j$ coupling scheme. Our results indicate that: (i) the newly observed states $Ω_b(6316)^-$ and $Ω_b(6330)^-$ are good candidates of the light spin $j=1$ states, while the spin-parity $J^P=1/2^-$ and $J^P=3/2^-$ cannot be distinguished. The other two states, $Ω_b(6340)$ and $Ω_b(6350)$ mostly correspond to the light spin $j=2$ states, while the spin-parity $J^P=3/2^-$ and $J^P=5/2^-$ cannot be distinguished as well.(ii) The $2S$ states with spin-parity $J^P=1/2^+$ and $J^P=3/2^+$, respectively, might be narrow states with a width of $Γ<2$ MeV. (iii) The $1D$ states are not broad and the total decay widths vary from several to dozens of MeV, which have a good potential to be observed in future experiments.

description: Increasing evidence has demonstrated that regulatory RNA elements such as riboswitches (RS) play a pivotal role in the fine-tuning of bacterial gene expression. In this study, we investigated and characterized a novel transcriptional thiamine pyrophosphate (TPP) RS in the obligate human pathogen N. meningitidis MC58 (serogroup B). This RS is located in the 5´ untranslated region upstream of thiC gene, encoding a protein involved in TPP biosynthesis, an essential cofactor for all living beings. Primer extension revealed the transcriptional start site of thiC. Northern blot analysis of thiC mRNA and reporter gene studies confirmed the presence of an active TPP-sensing RS. Expression patterns of the wild-type RS and site-specific mutants showed that it is an OFF switch that controls transcription elongation of thiC mRNA. Interestingly, the regulatory mechanism of the meningococcal thiC RS resembles the Gram-positive Bacillus subtilis thiC RS rather than the Gram-negative Escherichia coli thiC RS. Therefore, the meningococcal thiC RS represents a rare example of transcriptional RS in a Gram-negative bacterium. We further observed that the RS is actively involved in modulating gene expression in response to different growth media and to supplemented bacterial and eukaryotic cell lysates as possible sources of nutrients in the nasopharynx. Our results suggest that RS-mediated gene regulation could influence meningococcal fitness, through the fine-tuning of biosynthesis and scavenging of nutrients and cofactors, such as thiamine.

description: In the present work, we study the effect of a network approach on the final wealth distributions of, important in the relevant bibliography, agent-based-models. The original bibliography models reach a dynamical equilibrium state where the distribution of the wealth is stable. In those models each agent is able to interact with every other agent. In the first part of this work, the agents are considered as nodes of a network. They can interact only with agents directly linked with them in the network. The interactions between the agents follow the same rules as in the original models of the relevant bibliography. The networks in this part are Eros-Renyi. Each agent has a probability p to be linked with everyone else in the network. Through computer stimulations, we study the effects of the variation of p on the final wealth distributions. The conclusion is that the wealth distributions stay the same as the value of p changes. In the second part the agents are considered nodes of directed networks. Every agent has probability p to be linked with everyone else, but this time the wealth flows one-way only as the links are directed. The interaction rules of the original models are slightly modified in this case. We study the final wealth distributions of the dynamical equilibrium state as p value changes

description: Convolutional Neural Nets, which is a powerful method of Deep Learning, is applied to classify equation of state of heavy-ion collision event generated within the UrQMD model. Event-by-event transverse momentum and azimuthal angle distributions of protons are used to train a classifier. An overall accuracy of classification of 98\% is reached for Au+Au events at $\sqrt{s_{NN}} = 11$ GeV. Performance of classifiers, trained on events at different colliding energies, is investigated. Obtained results indicate extensive possibilities of application of Deep Learning methods to other problems in physics of heavy-ion collisions.

description: In many particle physics models, domain wall can form during the phase transition process after discrete symmetry breaking. We study the scenario within a complex singlet extended Standard Model framework, where a strongly first order phase transition can occur depending on the hidden scalar mass and the mixing between the extra heavy Higgs and the SM Higgs mass. The gravitational wave spectrum is of a typical two-peak shape, the amplitude and the peak from the strongly first order phase transition is able to be probed by the future space-based interferometers, and the one locates around the peak from the domain wall decay is far beyond the capability of the current PTA, and future SKA.

Toward a better understanding of the chronic pain experiences of Indigenous women who experience violence : implications for nursing education, practice and research
Creators: name: Heino, Angela Nicole
Publisher: name: The University of British Columbia
Year: 2018

description: Problem/Issue and significance: Intimate partner violence [IPV] is a critically urgent public health issue worldwide. Violence and trauma have multiple short- and long-term health effects including pain, which is a complex, highly subjective experience that can have profoundly negative impacts on both “body and soul.” Untreated pain can become chronic and debilitating, leading to a lower quality of life, decreased employment opportunities, and increased mental health concerns. Addressing pain is an important aspect of the health care professional’s role, and the failure to do so can exacerbate existing health disparities and worsen health outcomes. Current approaches to understanding and managing pain are primarily based on a Westernized view of health and illness. Diversity in knowledge and perspectives is missing from clinical practice, nursing education, and research, and is needed to improve pain assessment and management practices. Approach or innovation: While health care practitioners recognize that more holistic approaches to understanding, assessing, and treating pain are required, the significance of women’s chronic pain experiences in the context of IPV has been largely unexplored. This paper proposes the creation of “pain profiles” using an approach that draws of multiple sources of information and types of knowledge to gain new insights and to develop a richer understanding of women’s pain experiences. The unique circumstances and experiences of Indigenous women are used to illustrate the usefulness of the pain profiles as a case in point. In Canada, Indigenous women experience higher levels of violence and trauma as a result of interpersonal violence, historical trauma, and ongoing socio-economic inequities and systemic racism than non-Indigenous women. When Indigenous women seek health care for pain, they often report a lack of culturally safe and appropriate services and are often labeled as “drug-seeking” which can cause further delays or avoiding seeking care. Few existing health services address pain arising from violence and trauma for women, especially services that focus on cultural safety and trauma-and-violence informed care. Lessons and implications: Pain profiles provide a novel and more nuanced approach to understanding, and addressing, pain in women who have experienced violence by using a holistic approach that draws on various perspectives and multiple sources of information, including the women’s own words. This approach may help to guide the implementation of more culturally safe, trauma-and-violence informed health practices and services, strengthen nursing curriculum around pain assessment and management, and help improve the overall well-being and quality of life of all women who have experienced violence.

description: We study in this paper the ground state energy of a free bosonic theory on a finite interval of length $R$ with either a pair of sine-Gordon type or a pair of Kondo type interactions at each boundary. This problem has potential applications in condensed matter (current through superconductor-Luttinger liquid-superconductor junctions) as well as in open string theory (tachyon condensation). While the application of Bethe ansatz techniques to this problem is in principle well known, considerable technical difficulties are encountered. These difficulties arise mainly from the way the bare couplings are encoded in the reflection matrices, and require complex analytic continuations, which we carry out in detail in a few cases.

description: We consider the swampland distance and de Sitter conjectures, of respective order one parameters $λ$ and $c$. Inspired by the recent Trans-Planckian Censorship conjecture (TCC), we propose a generalization of the distance conjecture, which bounds $λ$ to be a half of the TCC bound for $c$, i.e. $λ\geq \frac{1}{2}\sqrt{\frac{2}{3}}$ in 4d. In addition, we propose a correspondence between the two conjectures, relating the tower mass $m$ on the one side to the scalar potential $V$ on the other side schematically as $m\sim |V|^{\frac{1}{2}}$, in the large distance limit. These proposals suggest a generalization of the scalar weak gravity conjecture, and are supported by a variety of examples. The lower bound on $λ$ is verified explicitly in many cases in the literature. The TCC bound on $c$ is checked as well on ten different no-go theorems, which are worked-out in detail, and $V$ is analysed in the asymptotic limit. In particular, new results on 4d scalar potentials from type II compactifications are obtained.

We show that $κ(T,B)$ shows large oscillations in the high-field region (B > 2 T) where clear signs of the Quantum-Hall effect are observed in the Hall resistance. With the measured longitudinal electrical resistivity we show that the Wiedemann-Franz law is violated in the high-field regime.

description: Environment perception for autonomous driving is doomed by the trade-off between range-accuracy and resolution: current sensors that deliver very precise depth information are usually restricted to low resolution because of technology or cost limitations. In this work, we exploit depth information from an active gated imaging system based on cost-sensitive diode and CMOS technology. Learning a mapping between pixel intensities of three gated slices and depth produces a super-resolved depth map image with respectable relative accuracy of 5% in between 25-80 m. By design, depth information is perfectly aligned with pixel intensity values.
Elastic deformation of a fluid membrane upon colloid binding
Creators: name: Deserno, Markus
Publisher: name: arXiv
Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: When a colloidal particle adheres to a fluid membrane, it induces elastic deformations in the membrane which oppose its own binding. The structural and energetic aspects of this balance are theoretically studied within the framework of a Helfrich Hamiltonian. Based on the full nonlinear shape equations for the membrane profile, a line of continuous binding transitions and a second line of discontinuous envelopment transitions are found, which meet at an unusual triple point. The regime of low tension is studied analytically using a small gradient expansion, while in the limit of large tension scaling arguments are derived which quantify the asymptotic behavior of phase boundary, degree of wrapping, and energy barrier. The maturation of animal viruses by budding is discussed as a biological example of such colloid-membrane interaction events.

description: Sufficient dimension reduction (SDR) techniques have proven to be very useful data analysis tools in various applications. Conventional SDR methods mainly tackle simple vector-valued predictors, but they are inappropriate for data with array (tensor)-valued predictors. In this paper, we propose a tensor dimension reduction approach based on inverse regression, and we refer to it as T-IRE, which reduces the dimension of original array-valued predictors while simultaneously retaining the structural information within predictors and the proposed method also provides an efficient estimation algorithm. Empirical performance and two dataset analysis demonstrate the advantages of our proposed method.

Continuity properties of these objects through a crossing sphere are proved. In the case of spherical symmetry Dray--t'Hooft--Redmount formula results from continuity property of the corresponding object.

description: Assessing the structural properties of large proteins is important to gain an understanding of their function in, e.g., biological systems or biomedical applications. We propose a method to examine the mechanical properties of proteins subject to applied forces by means of multiscale simulation. We consider both stretching and torsional forces, which can be applied independently of each other. We apply torsional forces to a coarse-grained continuum model of the antibody protein immunoglobulin G (IgG) using Fluctuating Finite Element Analysis and identify the area of strongest deformation. This region is essential to the torsional properties of the molecule as a whole, as it represents the softest, most deformable domain. We subject this part of the molecule to torques and stretching forces on an atomistic level, using molecular dynamics simulations, in order to investigate its torsional properties. We calculate the torsional resistance as a function of the rotation of the domain, while subjecting it to various stretching forces. We learn how these obtained torsion profiles evolve with increasing stretching force and show that they exhibit torsion stiffening, which is in qualitative agreement with experimental findings. We argue that combining the torsion profiles for various stretching forces effectively results in a combined force-torque spectroscopy analysis, which may serve as a mechanical signature for the examined molecule.

description: The main objective of the study is the quantitative characteristics of the business cycle in agriculture in Poland in 1991-2016. The first part of the article is devoted to the theory of cyclical fluctuations in the agriculture. The second part includes an empirical analysis. The investigation of the agricultural business cycle is based on the year-to-year dynamics of the gross value added and final output. On the basis of the added value it was possible to identify four full cycles: (1) 1996-2000; (2) 2001-2006; (3) 2007-2012; (4) 2013-2015. Using the final output, it was considered that also in this case, four cycles can be determined: (1) up to 2000; (2) 2001-2006; (3) 2007-2010; (4) 2011-2015. The cycles’ duration was usually 3-6 years. However, the phases most frequently lasted from 2 to 4 years. On the basis of the analysis, it was also concluded that the amplitude of the entire cycle of gross value added as well as of its individual phases was always, in absolute terms, higher than the amplitude of the final production cycle and phases. The highest absolute amplitude was observed for the cycle of gross value added in 2013-2015.

Input data to the network constitute magnetic signals measured by a Rogowski coil (plasma current), magnetic pick-up coils (normal and tangential components of magnetic fields) and flux loops (poloidal magnetic fluxes). The developed neural networks fully reconstruct not only the poloidal flux function $ψ\left( R, Z\right)$ but also the toroidal current density function $j_ϕ\left( R, Z\right)$ with the off-line EFIT quality. To preserve robustness of the networks against a few missing input data, an imputation scheme is utilized to eliminate the required additional training sets with large number of possible combinations of the missing inputs.

description: The clinicoanatomic cases of acquired pedophilia that have been published in the medical and forensic literature up to 2019 are reviewed. Twenty-two cases fit our inclusion criteria. All but one were men, and in only one case the injury was localized to the left hemisphere. Hypersexuality was present in 18 cases. The damaged areas fell within the frontotemporoinsular cortices and related subcortical nuclei; however, the anterior hypothalamus was spared. Damage to parts of the right frontotemporoinsular lobes with sparing of the anterior hypothalamus seems to be critical for the emergence of acquired pedophilia.

description: The emission properties of atoms lie at the foundations of both quantum theory and light-matter interactions. In the context of macroscopic media, exact knowledge thereof is important both in current quantum technologies as well as in fundamental studies. While for isotropic media, this is a very well-studied problem, there are still big gaps in the theory of anisotropic media. In particular, to the best of our knowledge, an explicit expression for the spontaneous emission rate in general anisotropic media has not been presented. In this work, we first derive the quantised electromagnetic field operators to calculate the emission rate in uniaxial media. For the more general case of biaxial media we propose an approximate expression based on interpolation between the limiting cases of uniaxial media. We support our model with numerical simulations which are in strong agreement for typical media configurations, and furthermore show how local field effects can be taken into account in the model.

Nurse practitioner residency programs : a literature review
Creators: name: Constantino, Maridel
Publisher: name: The University of British Columbia
Year: 2018

description: New-graduate Nurse Practitioners (NPs) have identified many challenges during the transition period from a student to a full-scope NP. Some of these challenges included the inability to practice at full-scope, which caused role ambiguity. Consequently, role ambiguity has led to poor job satisfaction and low retention rates. Nurse Practitioner Residency Programs (NPRPs) have been explored as a viable support option for new-graduate NPs during the transition period. The primary objectives of this literature review were to 1.) examine participant perceptions on the usefulness of NPRPs to facilitate a smooth transition from a student NP to a full-scope NP, 2.) determine the most effective program structure, and 3.) identify the barriers preventing the development of NPRPs. The secondary objective of this project was to create a NPRP prototype framework that could be used within the Canadian health care system. Based on the current literature, the findings showed that NPs perceived NPRPs to be useful during the transition period because it increased clinical knowledge, built confidence, consolidated skills, clarified duty boundaries, and successfully integrated NPs into the health care team. Secondly, the findings revealed the most effective program structure to include combined didactic and clinical experiences, reflective journaling, regular performance assessments, and comprehensive program evaluations. Thirdly, the barriers recognized in the literature included inadequate funding, insufficient research regarding the impact of NPRPs, a failure to standardize programs, and the lack of support from key stakeholders. Using the findings from objectives one and two, a NPRP prototype framework, called the Canadian Nurse Practitioner Residency Program, was created. Finally, using the findings from objective three, key recommendations for future NPRPs were provided.

description: The adsorption of highly charged flexible polycations and polyanions on a charged cylindrical substrate is investigated by means of Monte Carlo (MC) simulations. A detailed structural study, including monomer and fluid charge distributions, is provided. The influence of a short range attraction between the polycations and the negatively charged substrate is also considered. We demonstrate that the building up of multilayer structures is highly prohibited mainly due to the high entropy penalty stemming from the low dimensionality of the substrate at strong curvature.

description: The importance of packaging functions is still growing and, consequently, the approach to packaging is more innovative and creative, resulting in the creation of packaging with innovative features in the form of active and intelligent packaging. This paper explores preferential packaging functions and preferences of customers according to intelligent and active packaging. The survey was conducted with 200 respondents, who can be defined as the millennials (people born in 1980-2000). This age group was chosen due to previous research results, which confirmed that intelligent and active packaging are most attractive for respondents of this age. Protection function is still perceived as the primary one and most importantly ensuring the freshness and shelf life of products. Respondents’ interest is slightly higher in active packaging as they extend the protection of the product and thus extend shelf life of the product, but also its safety. The analysis allows for more specific suggestions for active and intelligent packaging marketing with respect to the customers’ requirements.

description: We have observed signatures of resonant tunneling in an Al three-junction qubit, inductively coupled to a Nb LC tank circuit. The resonant properties of the tank oscillator are sensitive to the effective susceptibility (or inductance) of the qubit, which changes drastically as its flux states pass through degeneracy. The tunneling amplitude is estimated from the data. We find good agreement with the theoretical predictions in the regime of their validity.

description: Nanostructures with one-dimensional periodicity, such as multilayered structures, are currently in the focus of active research in the context of hyperbolic metamaterials and photonic topological structures. An efficient way to describe the materials with subwavelength periodicity is based on the concept of effective material parameters, which can be rigorously derived incorporating both local and nonlocal responses. However, to provide any predictions relevant for applications, effective material parameters have to be supplemented by appropriate boundary conditions. In this work, we provide a comprehensive treatment of spatially dispersive bulk properties of multilayered metamaterials as well as derive boundary conditions for the averaged fields. We demonstrate that local bianisotropic model does not capture all the features related to second-order nonlocal effects in the bulk of metamaterial. As we prove, while the bulk response of multilayers does not depend on the unit cell choice, effective boundary conditions are strongly sensitive to the sequence of layers and multilayer termination. The developed theory provides a clear interpretation of the recent experiments on the reflectance of all-dielectric deeply subwavelength multilayers suggesting further avenues to experimentally probe electromagnetic nonlocality in metamaterials.
