We report the stopping of an atomic beam, using a series of pulsed electromagnetic coils. We use a supersonic beam of metastable neon created in a gas discharge as a monochromatic source of paramagnetic atoms. A series of coils is fired in a timed sequence to bring the atoms to near rest, where they are detected on a microchannel plate. Applications to fundamental problems in physics and chemistry are discussed.

No FDA-approved medications for methamphetamine (MA) use disorder (MUD) are available. Suvorexant (SUVO), a dual orexin receptor antagonist that is FDA approved for insomnia treatment, reduces MA self-administration and MA-induced reinstatement responding in preclinical studies. SUVO may also reduce MA use by targeting substance use risk factors, including insomnia, stress, cue reactivity, and craving.

Background: The Apple Watch provides promising health data that could aid in increasing exercise adherence; regular exercise can help individuals manage and prevent diseases such as obesity and cardiovascular disease. However, the impact of skin pigmentation on the accuracy of the Apple Watch Series 9 for measures of energy expenditure (EE) and heart rate (HR) is unknown.
Purpose: The purpose of this study was to determine the accuracy of the Apple Watch Series 9 on various skin pigmentations for measures of EE and HR.

The dual-active-bridge series-resonant converter, offering galvanic isolation and high power density, is a viable and attractive solution for the isolated DC/DC power stage in Solid-State Transformers. Under the step load commands, the resonant tanks typically experience severe oscillations, which delay the transient response and the entry into the final steady state. To address these drawbacks, this paper proposes a dynamic trajectory prediction modulation (DTPM) method for adjusting the transient process.

Unlabelled: Exercise-induced pulmonary arterial hypertension (EiPH) is often treated with off-label use of pulmonary arterial hypertension-targeted therapy (PH-targeted therapy). Most measures of PAH severity are normal in patients with EiPH, posing challenges in evaluating for physiological improvement in patients treated for EiPH. In this study, we used non-invasive cardiopulmonary exercise testing (CPET) to assess for objective improvement in patients treated for EiPH.

Sleep apnea/hypopnea is a sleep disorder characterized by repeated pauses in breathing which could induce a series of health problems such as cardiovascular disease (CVD) and even sudden death. Polysomnography (PSG) is the most common way to diagnose sleep apnea/hypopnea. Considering that PSG data acquisition is complex and the diagnosis of sleep apnea/hypopnea requires manual scoring, it is very time-consuming and highly professional.
