A Micromachined Silicon-on-Glass Accelerometer with an Optimized Comb Finger Gap Arrangement

open access: yesMicromachines
This paper reports the design, fabrication, and characterization of a MEMS capacitive accelerometer with an asymmetrical comb finger arrangement. By optimizing the ratio of the gaps of a rotor finger to its two adjacent stator fingers, the sensitivity of

Oxidative stress and impaired cardiovagal baroreflex sensitivity in young adults with post‐traumatic stress disorder

open access: yesExperimental Physiology, EarlyView.
Abstract Post‐traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, yet the underlying physiological characterization in young adults remain unclear. This study examines whether autonomic and/or vascular dysfunction predominates as an early precursor to CVD development in young adults with PTSD and explores the

External Vibrations on Early‐Age Concrete: A Review

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

First Results from ABRACADABRA-10cm: A Search for Low-Mass Axion Dark Matter

open access: yes, 2019
The presence of dark matter provides some of the most tangible evidence for the existence of physics beyond the Standard Model. One compelling dark matter candidate is the axion, a light boson that was originally postulated as a solution to another ...

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.
