Temperature-Induced Plasmon Excitations for the - Lattice in Perpendicular Magnetic Field.

We have investigated the α-T3 model in the presence of a mass term which opens a gap in the energy dispersive spectrum, as well as under a uniform perpendicular quantizing magnetic field. The gap opening mass term plays the role of Zeeman splitting at low magnetic fields for this pseudospin-1 system, and, as a consequence, we are able to compare physical properties of the the α-T3 model at low and high magnetic fields. Specifically, we explore the magnetoplasmon dispersion relation in these two extreme limits.

Screening in Graphene: Response to External Static Electric Field and an Image-Potential Problem.

We present a detailed first-principles investigation of the response of a free-standing graphene sheet to an external perpendicular static electric field . The charge density distribution in the vicinity of the graphene monolayer that is caused by was determined using the pseudopotential density-functional theory approach. Different geometries were considered.

Examining inequities in rates of undiagnosed HIV and rectal STIs in a large nationwide cohort study of sexual minority men.

Objective: Sexual minority men (SMM) of colour are disproportionately impacted by HIV and bacterial STIs (bSTIs). To better understand within-group heterogeneity and differential risk factors by race and ethnicity, we sought to examine rates of undiagnosed HIV and rectal bSTI at the intersection of racial and ethnic identity with other sociodemographic factors.

Methods: We examined data from 8105 SMM conducting home-based self-testing at enrolment in a nationwide cohort study collected from November 2017 to August 2018.

The role of outdoor microclimatic features at long-term care facilities in advancing the health of its residents: An integrative review and future strategies.

Projections show that Earth's climate will continue to warm concurrent with increases in the percentage of the world's elderly population. With an understanding that the body's resilience to the heat degrades as it ages, these coupled phenomena point to serious concerns of heat-related mortality in growing elderly populations. As many of the people in this age cohort choose to live in managed long-term care facilities, it's imperative that outdoor spaces of these communities be made thermally comfortable so that connections with nature and the promotion of non-sedentary activities are maintained.

Partners' Consensus About Joint Effort and COVID-19 Prevention Among Sexual Minority Men.

The current study examined the relevance of relationship functioning to partners' agreement or consensus about joint effort surrounding COVID-19 prevention. Interdependence theory has been widely used to understand how relationship partners influence health behavior, including how sexual minority male (SMM) couples regulate HIV risk. Couples with better relationship functioning tend to be more successful at negotiating joint (shared) goals and subsequently accomplishing them.

Stewardship of global collective behavior.

Collective behavior provides a framework for understanding how the actions and properties of groups emerge from the way individuals generate and share information. In humans, information flows were initially shaped by natural selection yet are increasingly structured by emerging communication technologies. Our larger, more complex social networks now transfer high-fidelity information over vast distances at low cost.

The Role of Anger in Traumatic Harm and Recovery for Sexual Violence Survivors.

Sexual violence is a strong predictor of posttraumatic stress disorder (PTSD). Sexual violence survivors presenting for PTSD treatment may experience and express a range of distressing emotions. An extensive body of research guides clinical conceptualization and targeting of fear responses in PTSD treatment.

Population-Specific Correlates of Sexual Arrangements and Communication in a National Sample of Latinx Sexual Minority Men.

While the literature on sexual arrangements has expanded considerably, less is known about sexual arrangements among ethnically diverse populations, particularly Latinx sexual minority men (LSMM). Relationship research may overlook culturally salient correlates (e.g.

Atomistic Band-Structure Computation for Investigating Coulomb Dephasing and Impurity Scattering Rates of Electrons in Graphene.

In this paper, by introducing a generalized quantum-kinetic model which is coupled self-consistently with Maxwell and Boltzmann transport equations, we elucidate the significance of using input from first-principles band-structure computations for an accurate description of ultra-fast dephasing and scattering dynamics of electrons in graphene. In particular, we start with the tight-binding model (TBM) for calculating band structures of solid covalent crystals based on localized Wannier orbital functions, where the employed hopping integrals in TBM have been parameterized for various covalent bonds. After that, the general TBM formalism has been applied to graphene to obtain both band structures and wave functions of electrons beyond the regime of effective low-energy theory.

Disproportionate multimorbidity among veterans in middle age.

Background: Little is known about the prevalence of multimorbidity among middle-aged veterans. Multimorbidity holds implications for planning for a population with high health care utilization, poor quality of life and marked need for interdisciplinary care.

Methods: The current study used the US 2017 Behavior Risk Factor Surveillance System to measure multimorbidity in three ways: (1) reporting two or more health conditions, (2) reporting two or more conditions controlling for demographic characteristics (e.

CO utilization in built environment the swing carbonation of alkaline solid wastes with different mineralogy.

Carbon mineralization to solid carbonates is one of the reaction pathways that can not only utilize captured CO2 but also potentially store it in the long term. In this study, the dissolution and carbonation behaviors of alkaline solid wastes (i.e.

Current State of Targeted Radiometal-Based Constructs for the Detection and Treatment of Disease in the Brain.

The continual development of radiopharmaceutical agents for the field of nuclear medicine is integral to promoting the necessity of personalized medicine. One way to greatly expand the selection of radiopharmaceuticals available is to broaden the range of radionuclides employed in such agents. Widening the scope of development to include radiometals with their variety of physical decay characteristics and chemical properties opens up a myriad of possibilities for new actively targeted molecules and bioconjugates.

Nutritional geometry of female chimpanzees (Pan troglodytes).

Primate foraging is influenced by the spatial and temporal distribution of foods, which may facilitate or constrain optimal nutrient intakes. Chimpanzees are frugivorous primates that mainly subsist on ripe fruit that is typically low in available protein (AP) and high in easily digestible carbohydrates. Because chimpanzees prefer ripe fruit and often eat it in large quantities compared with other foods, we hypothesized that protein intake would be tightly regulated while non-protein energy (NPE) would vary with fruit intake.

Stress-Related Growth Among Transgender Women: Measurement, Correlates, and Insights for Clinical Interventions.

Although transgender women (TGW), and especially TGW of color, are disproportionately exposed to discrimination and violence, many of them experience stress-related growth. However, little is known about the experience of stress-related growth and its correlates among TGW. Using data from a racially-diverse sample of 210 TGW, the short version of the Stress-Related Growth Scale was modified to assess growth as a result of coming to terms with one's transgender identity among TGW.

Development of Motivational Interviewing Treatment Integrity (MITI) Fidelity Codes Assessing Motivational Interviewing with Couples.

This study evaluated preliminary reliability and validity evidence for novel scores that extend the motivational interviewing treatment integrity (MITI) coding system to assess elements unique to motivational interviewing (MI) with couples. We recruited 20 cismale couples where at least one partner was aged 18-29; reported substance use; and was HIV-negative. Couples were randomized to a three-session MI or attention-matched education control.

mHealth for transgender and gender-expansive youth: harnessing gender-affirmative cross-disciplinary innovations to advance HIV prevention and care interventions.

Transgender and gender-expansive (TGE) youth endure stark disparities in health and wellbeing compared to their cisgender peers. A key social determinant of health for TGE adolescents and emerging adults is gender affirmation, which encompasses multidimensional validations of an individual's lived gender. Lacking available resources for one's gender affirmation, TGE young people may engage in high-risk maladaptive coping behaviors, linked to their disproportionately high HIV-acquisition risk.

Utilization of Host Cell Chromosome Conformation by Viral Pathogens: Knowing When to Hold and When to Fold.

Though viruses have their own genomes, many depend on the nuclear environment of their hosts for replication and survival. A substantial body of work has therefore been devoted to understanding how viral and eukaryotic genomes interact. Recent advances in chromosome conformation capture technologies have provided unprecedented opportunities to visualize how mammalian genomes are organized and, by extension, how packaging of nuclear DNA impacts cellular processes.

Targeting PVT1 Exon 9 Re-Expresses Claudin 4 Protein and Inhibits Migration by Claudin-Low Triple Negative Breast Cancer Cells.

PVT1 is a long non-coding RNA transcribed from a gene located at the 8q24 chromosomal region that has been implicated in multiple cancers including breast cancer (BC). Amplification of the 8q24 chromosomal region is a common event in BC and is associated with poor clinical outcomes. Claudin-low (CL) triple negative breast cancer (TNBC) is a subtype of BC with a particularly dismal outcome.

Prostac: A New Composite Score With Potential Predictive Value in Prostate Cancer.

Prostate cancer (PCa) is the most commonly diagnosed solid organ cancer in men worldwide. Current diagnosis of PCa includes use of initial prostate specific antigen assay which has a high false positive rate, low specificity, and low sensitivity. The side effects of unnecessary prostate biopsies that healthy men are subjected to, often result in unintended health complications.

Risk Analysis of COVID-19 Infections in Kolkata Metropolitan City: A GIS-Based Study and Policy Implications.

The COVID-19 pandemic has affected daily lives of people around the world. People have already started to live wearing masks, keeping a safe distance from others, and maintaining a high level of hygiene. This paper deals with an in-depth analysis of riskness associated with COVID-19 infections in Kolkata Municipal Corporation (KMC) at the subcity (ward) level.

Understanding Shame as an Obstacle: Toward a Global Perspective.

In this paper, the authors suggest that shame is a barrier to many patients' willingness to disclose their history of trauma to nurses and other members of the healthcare team and that the clinicians participate in this withholding of information because of their experience of vicarious shame. The authors propose that shame and vicarious shame reduce the accuracy of assessment, limit the nurse-patient relationship, and reduce the ability of the healthcare teams to accurately diagnose and treat patients. Shame as a barrier to trauma assessment is also considered in light of the Roy adaptation model and from a global perspective.

The importance of domain-specific self-efficacy assessment for substance use and HIV care continuum outcomes among adults in an urban HIV clinic network.

Despite the prominence of self-efficacy as a predictor of antiretroviral therapy (ART) adherence, relatively little work has examined domain-specific associations with steps in the care continuum or the possibility that substance use may have domain-specific associations with self-efficacy. This study analyzed data from a sample of 174 people living with HIV recruited through three clinics in the New York City metro area. Consistent with hypotheses, path analysis showed that appointments kept and viral load were each predicted only by their respective domain-specific self-efficacy components (i.

Evolution of water conservation in humans.

To sustain life, humans and other terrestrial animals must maintain a tight balance of water gain and water loss each day. However, the evolution of human water balance physiology is poorly understood due to the absence of comparative measures from other hominoids. While humans drink daily to maintain water balance, rainforest-living great apes typically obtain adequate water from their food and can go days or weeks without drinking.
