Gated InAs quantum dots embedded in surface acoustic wave cavities for low-noise optomechanics.

Self-assembled InAs quantum dots (QDs) are promising optomechanical elements due to their excellent photonic properties and sensitivity to local strain fields. Microwave-frequency modulation of photons scattered from these efficient quantum emitters has been recently demonstrated using surface acoustic wave (SAW) cavities. However, for optimal performance, a gate structure is required to deterministically control the charge state and reduce the charge noise of the QDs.

Cost and cost-effectiveness of abstinence-contingent wage supplements for adults experiencing homelessness and alcohol use disorder.

Background: Alcohol use disorder, unemployment, and risk of homelessness are linked and often co-occurring, but most interventions do not address both alcohol use disorder and unemployment. The Abstinence-Contingent Wage Supplement (ACWS) model of the Therapeutic Workplace offers participants stipends or wage supplements contingent on both their abstaining from alcohol and engaging with an employment specialist or working in a community job. Wearable biosensors continuously tracked alcohol use.

Monolithic Polarizing Circular Dielectric Gratings on Bulk Substrates for Improved Photon Collection from InAs Quantum Dots.

III-V semiconductor quantum dots (QDs) are near-ideal and versatile single-photon sources. Because of the capacity for monolithic integration with photonic structures as well as optoelectronic and optomechanical systems, they are proving useful in an increasingly broad application space. Here, we develop monolithic circular dielectric gratings on bulk substrates - as opposed to suspended or wafer-bonded substrates - for greatly improved photon collection from InAs quantum dots.

Evolving Disparities in Cannabis Use Among Youth by Demographics and Tobacco and Alcohol Use in the U.S.: 2013-2021.

Introduction: This study investigated the prevalence of past 30-day cannabis use among U.S. youth by cigarette use, alcohol use, demographics, and state-of-residence cannabis legal status in 2021 and examined whether changes in cannabis use prevalence were modified by these factors from 2013 to 2021.

Asthma prevalence among US 9th-12th graders who report past 30-day cannabis use in 2019.

Introduction: Little is known about the relationship between cannabis use and asthma among youth in the US. The aims of this study were to estimate prevalence of asthma among youth who reported any cannabis use in the past 30 days, relative to those who did not, and to investigate the relationship between frequency of cannabis use and prevalence of asthma, adjusting for demographic characteristics and cigarette use.

Methods: Data were drawn from the 2019 Youth Risk Behavior Surveillance System (YRBSS), a CDC national high school survey, which collects data from students in grades 9-12 across the US bi-annually.

Cannabis use and the prevalence of current asthma among adolescents and adults in the United States.

Objectives: Cannabis use has increased among adolescents and adults in the United States (US) in recent years. Few data are available on the prevalence of asthma by frequency of cannabis use. This study aimed to estimate the prevalence of asthma by frequency of past 30-day cannabis use among US individuals.

Long-Term Effects of Incentives for HIV Viral Suppression: A Randomized Clinical Trial.

Achieving viral suppression in people living with HIV improves their quality of life and can help end the HIV/AIDS epidemic. However, few interventions have successfully promoted HIV viral suppression. The purpose of this study was to evaluate the long-term effectiveness of financial incentives for viral suppression in people living with HIV.

Discounting of employment opportunities with urine drug testing requirements in opioid users enrolled in the Therapeutic Workplace.

Background: The evidence-based Therapeutic Workplace (TWP) is a promising employment-based treatment where access to work is contingent on objective evidence of abstinence from drugs. TWP is sometimes criticized for requiring individuals who use drugs to voluntarily enroll in a program requiring urine drug testing.

Objective: This experiment was conducted to assess whether urine drug testing as a condition of employment decreases the value of employment opportunities and to what degree.

Assessing the Association of Solitary Confinement Ban With Adolescent Self-Harm in New York City Jails.

This study sought to evaluate the association of a solitary confinement ban with self-harm among adolescents in New York City's jail system. Data were extracted from medical records on 5,038 adolescent incarcerations from October 1, 2013, through July 12, 2016, and compared incarcerations before the ban (February 20, 2015) with those after the ban. Of the 2,503 adolescent incarcerations pre-ban, there were 171 self-harm gestures among 106 incarcerations (4.

Central Obesity Is Associated With an Increased Rate of Multisite Pain in Older Adults.

Objective: Central obesity has been associated with several adverse health events, but little research exists about the longitudinal effects of central obesity on multisite pain. The purpose of this study was to assess if central obesity, as measured by waist circumference measurement, was associated with an increased rate of having multisite pain among older adults aged 65 years and older.

Design: The National Health and Aging Trends Study is a longitudinal cohort study initiated in 2011 and intended to be representative of Medicare beneficiaries in the contiguous United States.

Being at work improves stress, craving, and mood for people with opioid use disorder: Ecological momentary assessment during a randomized trial of experimental employment in a contingency-management-based therapeutic workplace.

Employment problems are common among people with substance use disorders (SUDs), and improving vocational functioning is an important aspect of SUD treatment. More detailed understanding of the psychosocial benefits of employment may help refine vocational interventions for people with SUDs. Here, we used ecological momentary assessment to measure possible affective improvements associated with work.

The Association of Pain Levels and Low Physical Activity among Older Women.

There is an integral research gap regarding whether there is a relationship between pain levels and low physical activity among older women. This is a secondary analysis of a longitudinal cohort study, the Women's Health and Aging Study (WHAS) II. Our analyses included 436 community-dwelling women between the ages of 70 and 79, who were followed for 10.

Psychosocial Interventions to Promote Undetectable HIV Viral Loads: A Systematic Review of Randomized Clinical Trials.

Suppressing HIV viral loads to undetectable levels is essential for ending the HIV/AIDS epidemic. We evaluated randomized controlled trials aimed to increase antiretroviral medication adherence and promote undetectable viral loads among people living with HIV through November 22, 2019. We extracted data from 51 eligible interventions and analyzed the results using random effects models to compare intervention effects between groups within each intervention and across interventions.

Poor Lower Extremity Functioning Is Associated with Modest Increased Incidence of Probable Dementia.

Lower extremity functioning in older adults provides a measure of poor physical performance and can predict negative health outcomes. The consequences of reduced lower extremity functioning on cognitive decline, measured as time-varying variables, have not been well documented in previous studies. We aimed to evaluate whether lower extremity functioning is associated with an increased incidence rate of probable dementia among older adults using data from the National Health and Aging Trends Study (NHATS).

Cost and Cost-Effectiveness of Incentives for Viral Suppression in People Living with HIV.

Only 63% of people living with HIV in the United States are achieving viral suppression. Structural and social barriers limit adherence to antiretroviral therapy which furthers the HIV epidemic while increasing health care costs. This study calculated the cost and cost-effectiveness of a contingency management intervention with cash incentives.
