Pulmonary Veno‐Occlusive Disease: A Focused Clinicopathologic Series

open access: yesPulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Pulmonary veno‐occlusive disease (PVOD) is a rare and aggressive subtype of pulmonary arterial hypertension characterized by fibroproliferative obstruction of post‐capillary pulmonary venules leading to increased pulmonary vascular resistance and progressive right ventricular failure.

Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

open access: yesCarbon 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 ...

The Emission Geometry of Pulsars with Interpulses

open access: yesThe Astrophysical Journal
We present polarization profiles of 23 pulsars exhibiting interpulse (IP) emissions using the Five-hundred-meter Aperture Spherical Radio Telescope. By applying the rotating vector model (RVM), we measured the inclination and impact angles for 16 pulsars,

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

open access: yesCarbon Energy, Volume 8, Issue 6, June 2026.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.

Proteomic and Super‐Resolution Analyses of Murine Brown Adipocyte‐Derived Extracellular Vesicles

open access: yesJournal 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.

A Search for Pulsars in Steep Spectrum Radio Sources

open access: yes, 2018
We report on a time-domain search for pulsars in 44 steep spectrum radio sources originally identified from recent imaging surveys. The time-domain search was conducted at 327 MHz using the Ooty radio telescope, and utilized a semicoherent dedispersion ...

Nature of Ultralong Period Radio Transients: Could They Be Strange Dwarf Pulsars?

open access: yesThe Astrophysical Journal
Ultralong period radio transients (ULPTs), with periods of thousands of seconds, challenge conventional pulsar models. We propose that these isolated sources are strange dwarf (SD) pulsars—compact objects with a strange quark matter core surrounded by a ...

A Perspective of Multi‐Reflecting TOF MS

open access: yesMass Spectrometry Reviews, Volume 45, Issue 3, Page 476-506, May/June 2026.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.
