Perceptions and experiences of Korean American older adults with companion robots through long-term use: a comparative analysis of robot retention vs. return.

To date, limited research has been conducted on technology use among socially marginalized groups, such as older immigrants who may have limited digital literacy. This pilot study aims to explore Korean American older adults' perceptions and experiences with a companion version of the social robot, Hyodol. We hypothesize that the Hyodol robot's social presence may facilitate technology use among this sample.

Small-Angle X-ray Scattering (SAXS) Combined with SAXS-Driven Molecular Dynamics for Structural Analysis of Multistranded RNA Assemblies.

Nucleic acids (RNA and DNA) play crucial roles in all living organisms and find wide utility in clinical settings. The convergence of rationally designed nucleic acid multistranded assemblies with embedded therapeutic properties has led to the development of a platform based on nucleic acid nanoparticles (NANPs). NANPs incorporate various functional moieties to deliver their combinations to diseased cells in a highly controlled manner.

Perturbative analysis of the coherent state transformation in ab initio cavity quantum electrodynamics.

Experimental demonstrations of modified chemical structure and reactivity under strong light-matter coupling have spurred theoretical and computational efforts to uncover underlying mechanisms. Ab initio cavity quantum electrodynamics (QED) combines quantum chemistry with cavity QED to investigate these phenomena in detail. Unitary transformations of ab initio cavity QED Hamiltonians have been used to make them more computationally tractable.

Comparing parameterized and self-consistent approaches to ab initio cavity quantum electrodynamics for electronic strong coupling.

Molecules under strong or ultra-strong light-matter coupling present an intriguing route to modify chemical structure, properties, and reactivity. A rigorous theoretical treatment of such systems requires handling matter and photon degrees of freedom on an equal quantum mechanical footing. In the regime of molecular electronic strong or ultra-strong coupling to one or a few molecules, it is desirable to treat the molecular electronic degrees of freedom using the tools of ab initio quantum chemistry, yielding an approach referred to as ab initio cavity quantum electrodynamics (ai-QED), where the photon degrees of freedom are treated at the level of cavity QED.

Polaritonic Chemistry Using the Density Matrix Renormalization Group Method.

The emerging field of polaritonic chemistry explores the behavior of molecules under strong coupling with cavity modes. Despite recent developments in polaritonic methods for simulating polaritonic chemistry under electronic strong coupling, their capabilities are limited, especially in cases where the molecule also features strong electronic correlation. To bridge this gap, we have developed a novel method for cavity QED calculations utilizing the Density Matrix Renormalization Group (DMRG) algorithm in conjunction with the Pauli-Fierz Hamiltonian.

"I'll Be That One Cockblocking Friend": Understanding Student Experiences of Bystander Intervention in Alcohol-Related Sexual Assault.

The prevalence of sexual assault (SA) among college students (13%) is unacceptable, underreported, and alcohol use by the perpetrator or victim is reported in 50% of SA cases. Bystander intervention (BI) programs, which use prosocial behaviors to prevent or stop a harmful situation from occurring, have been implemented across college campuses to reduce SA. There are several known barriers (e.

Investigating Older Adults' Use of a Socially Assistive Robot via Time Series Clustering and User Profiling: Descriptive Analysis Study.

Background: The aging population and the shortage of geriatric care workers are major global concerns. Socially assistive robots (SARs) have the potential to address these issues, but developing SARs for various types of users is still in its infancy.

Objective: This study aims to examine the characteristics and use patterns of SARs.

COVID-19 Knowledge Among Sexual and Gender Minority Adults in New York City.

This study describes sources of COVID-19 vaccine information and COVID-19 knowledge among sexual and gender minority (SGM) adults in New York City (NYC). A sample of 986 SGM adults in NYC completed an online survey between June 25 and December 1, 2021. Participants indicated their top three sources of COVID-19 vaccine information from a list of 10 options.

Eighty years of national mental health policy: Exploring the inclusion of a human rights approach.

Mental health, historically framed as the mere absence of mental health disorders, has led to unequal treatment, resulting in more persons living with mental health challenges. This limited framing of mental health, often woven into policy and practices across a broad range of governance structures, programs, and services, has led to individual and collective discrimination and structural and systemic inequities, culminating in the infringement of fundamental human rights. Using a broader framework for viewing mental health (e.

Time to Elicit Physiological and Exertional Vigorous Responses from Daily Living Activities: Setting Foundations of an Empirical Definition of VILPA.

Purpose: Vigorous intermittent lifestyle physical activity (VILPA) are bursts of incidental vigorous activity that occur during day-to-day activities outside of the exercise-domain. Vigorous intermittent lifestyle physical activity has shown promise in lowering risk of mortality and chronic disease. However, there is an absence of an empirically derived definition.

Evolution of C-point singularities and polarization coverage of Poincaré-Bessel beam in self-healing process.

As a vector version of scalar Bessel beams, Poincaré-Bessel beams (PBBs) have attracted a great deal of attention due to their non-diffracting and self-healing properties as well as the presence of polarization singularities. Previous studies of PBBs have focused on cases that consist of a superposition of Bessel beams in orthogonal circular polarization states; here, we present a theoretical and experimental study of PBBs for which the polarization states are taken to be linear, which we call a linear PBB. Using a mode transformation of a full Poincaré beam constructed from linear polarization states, we observe the linear PBB as providing an in-principle infinite number of covers of the Poincaré sphere in the transverse plane and with an infinite number of C-points with positive and negative topological indices.

The effects of a tier 2 reading comprehension intervention aligned to tier 1 instruction for fourth graders with inattention and reading difficulties.

This study reports a secondary analysis from a quasi-experimental design study (N = 13 schools) to examine the effects of aligned Tier 1 (T1) and Tier 2 (T2) instruction for a subsample of fourth graders with inattention and reading difficulties. Of this sample (N = 63 students), 100% received free- or reduced-price lunch, 92% identified as Hispanic, and 22% received special education services. T1 instruction focused on implementing practices to support reading comprehension and content learning during social studies instruction.

MHConstructor: A high-throughput, haplotype-informed solution to the MHC assembly challenge.

The extremely high levels of genetic polymorphism within the human major histocompatibility complex (MHC) limit the usefulness of reference-based alignment methods for sequence assembly. We incorporate a short read assembly algorithm into a workflow for novel application to the MHC. MHConstructor is a containerized pipeline designed for high-throughput, haplotype-informed, reproducible assembly of both whole genome sequencing and target-capture short read data in large, population cohorts.

Synergistic innovations enabled the radiation of anglerfishes in the deep open ocean.

Major ecological transitions are thought to fuel diversification, but whether they are contingent on the evolution of certain traits called key innovations is unclear. Key innovations are routinely invoked to explain how lineages rapidly exploit new ecological opportunities. However, investigations of key innovations often focus on single traits rather than considering trait combinations that collectively produce effects of interest.

Women in Orthopaedics: 10-Year Trends of Fellowship Match Rate and Subspecialty.

Background: Orthopaedic surgery has consistently remained one of the least diverse specialties in medicine. There are limited data on the match rate by sex into orthopaedic fellowships.

Purpose: The goals of this study were to determine (1) how the percentage of women applying to orthopaedic fellowships has changed from 2011 to 2021, (2) whether there was a correlation between sex and the likelihood of a successful fellowship match, and (3) which subspecialties tend to have a greater proportion of female applicants and fellows.

A transformative shift in urban ecology toward a more active and relevant future for the field and for cities.

This paper builds on the expansion of urban ecology from a biologically based discipline-ecology in the city-to an increasingly interdisciplinary field-ecology of the city-to a transdisciplinary, knowledge to action endeavor-an ecology for and with the city. We build on this "prepositional journey" by proposing a transformative shift in urban ecology, and we present a framework for how the field may continue this shift. We conceptualize that urban ecology is in a state of flux, and that this shift is needed to transform urban ecology into a more engaged and action based field, and one that includes a diversity of actors willing to participate in the future of their cities.

Shifting forward: Urban ecology in perspective.

The world has become urban; cities increasingly shape our worldviews, relation to other species, and the large-scale, long-term decisions we make. Cities are nature, but they need to align better with other ecosystems to avoid accelerating climate change and loss of biodiversity. We need a science to guide urban development across the diverse realities of global cities.

Integrated analysis of gut metabolome, microbiome, and exfoliome data in an equine model of intestinal injury.

Background: The equine gastrointestinal (GI) microbiome has been described in the context of various diseases. The observed changes, however, have not been linked to host function and therefore it remains unclear how specific changes in the microbiome alter cellular and molecular pathways within the GI tract. Further, non-invasive techniques to examine the host gene expression profile of the GI mucosa have been described in horses but not evaluated in response to interventions.

Phototactic preference and its genetic basis in the planulae of the colonial Hydrozoan .

Background: Marine organisms with sessile adults commonly possess motile larval stages that make settlement decisions based on integrating environmental sensory cues. Phototaxis, the movement toward or away from light, is a common behavioral characteristic of aquatic and marine metazoan larvae, and of algae, protists, and fungi. In cnidarians, behavioral genomic investigations of motile planulae larvae have been conducted in anthozoans (corals and sea anemones) and scyphozoans (true jellyfish), but such studies are presently lacking in hydrozoans.

Intestinal energy harvest is associated with post-bariatric surgery weight loss.

Background/objectives: Metabolic and bariatric surgery (MBS) is the most effective treatment for severe obesity; however, a significant subset of patients does not achieve expected weight loss or have substantial weight recurrence over time. The intestinal energy harvest is a potential determinant of varying weight loss outcomes, but with limited exploration. We assess the relationships between diet, intestinal energy harvest, and weight outcomes over 24 months in individuals who have undergone MBS.

Changes in Healthcare Spending Attributable to High Deductible Health Plan Offer Among Enrollees with Comorbid Substance Use Disorder and Cardiovascular Disease.

Background: The rise in prevalence of high deductible health plans (HDHPs) in the United States may raise concerns for high-need, high-utilization populations such as those with comorbid chronic conditions. In this study, we examine changes in total and out-of-pocket (OOP) spending attributable to HDHPs for enrollees with comorbid substance use disorder (SUD) and cardiovascular disease (CVD).

Methods: We used de-identified administrative claims data from 2007 to 2017.
