Binary pulsars and tests of general relativity [PDF]

Proceedings of the International Astronomical Union, 2009
AbstractBinary pulsars are a valuable laboratory for gravitational experiments. Double-neutron-star systems such as the double pulsar provide the most stringent tests of strong-field gravity available to date, while pulsars with white-dwarf companions constrain departures from general relativity based on the difference in gravitational binding energies

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

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 ...

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

Carbon 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.

Cultural Adaptation and Implementation Strategy of a Recovery‐Oriented Mental Health Training Intervention (REFOCUS‐THAIREC) for Healthcare Workers in Thailand: An Experience‐Based Co‐Design

Health Expectations, Volume 29, Issue 3, June 2026.
ABSTRACT Background Healthcare workers are key in supporting mental health recovery, though the approach is poorly understood in many Asian countries. In Thailand, no recovery‐oriented training currently exists, highlighting the need for a culturally adapted intervention that incorporates locally meaningful concepts and clarifies unfamiliar recovery ...

Pulsars and Physics [PDF]

, 1992
Twenty-five years of active pulsar research have yielded a quite unexpected harvest of physical effects. These range from pleasing corroborations of well-established physical principles in unfamiliar environments to direct verification of the general ...

Pulsar magnetogyro ratios and pulsar evolution. III - Magnetic field generation

The Astrophysical Journal, 1984
Evidence to support the earlier contention that the primary mechanism of magnetic field generation in short-period (P< or approx. =0.5 s) pulsars is the thermally driven, Hall field limited battery effect is presented.

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.

Timing observations of southern pulsars [PDF]

, 1995
Pulse arrival-time measurements made at frequencies near 670 and 800 MHz over a 7-year period have been used to study the timing behaviour of 45 southern pulsars.

A Perspective of Multi‐Reflecting TOF MS

Mass 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.

Timing stability of three black widow pulsars [PDF]

, 2020
International audienceWe study the timing stability of three black widow pulsars (BWPs), both in terms of their long-term spin evolution and their shorter term orbital stability.
