Upper Limits on Pulsed Radio Emission from Unseen Compact Objects in Six Galactic Stellar Binaries
The Astrophysical JournalWe have conducted a search for radio pulsars in six Galactic stellar binary systems with unseen primary stars. All six systems have estimated primary masses in the range that could be consistent with neutron stars.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

On the aberration–retardation effects in pulsars
, 2009 The magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so-called radius-to-frequency mapping should be reflected in the aberration-retardation (A/R) effects that shift and/or delay the photons depending on

TMEM16A channel signalling microdomains in the regulation of vascular function
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Searching for Radio Pulses from Radio-quiet Gamma-Ray Pulsars with FAST
The Astrophysical JournalWe present periodicity and single-pulse searches at 1250 MHz for 22 “radio-quiet” gamma-ray pulsars, conducted using the Five-hundred-meter Aperture Spherical Radio Telescope. For PSR J1813−1246, we successfully detected pulsed signals with a spin period

Carbon and Hydrogen, Volume 28, Issue 2, Page 184-195, June 2026.Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...

High-sensitivity searches for radio pulsars [PDF]
, 1995 Radio pulsars are rapidly spinning, highly magnetized neutron stars which emit beams of radio waves and are observed to pulse when the beam crosses the Earth.

Proteomic and Super‐Resolution Analyses of Murine Brown Adipocyte‐Derived Extracellular Vesicles
Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.Graphical Abstract ABSTRACT Thermogenic brown adipocytes (BAs) are not only an energy sink but also regulate systemic metabolic health through secreted factors and extracellular vesicles (EVs). Here, we investigate the baseline profiles BA‐EVs and how cold‐induced thermogenesis alters the proteome of BA‐EVs.
