Magnetic fields generated by r-modes in accreting millisecond pulsars [PDF]

open access: yes, 2010
In rotating neutron stars the existence of the Coriolis force allows the presence of the so-called Rossby oscillations (r-modes) which are known to be unstable to emission of gravitational waves.

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe 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,

Discovery of Two Highly Scattered Pulsars from Image-based Circular Polarization Searches with the Australian SKA Pathfinder

open access: yesThe Astrophysical Journal
We report the discovery and timing of two pulsars from a sample of four circularly polarized sources identified in radio continuum images taken as part of the Australian SKA Pathfinder Variables and Slow Transients survey.

Finding Pulsars in Radio Images

open access: yes, 2021
Pulsars are a type of compact star that emit a beam of radio waves. As they spin regular pulses of radio waves can be seen here on Earth. They are both rare and difficult to detect, but are very useful both as a testing ground for physics and in the ...

Mechanisms regulating cerebral perfusion during running exercise: Influence of foot strike‐induced pulsatility oscillations, CO2 reactivity and BP

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Young, healthy males and females completed an incremental running test, demonstrating a progressive increase in middle cerebral artery blood velocity (MCAv) up to maximal exercise despite reductions in end‐tidal CO2. To investigate the underlying mechanism, foot‐strike timing was synchronized to the diastolic phase of the cardiac

Searching for Radio Pulses from Radio-quiet Gamma-Ray Pulsars with FAST

open access: yesThe Astrophysical Journal
We 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

The Zoo of Isolated Neutron Stars

open access: yesUniverse, 2023
In this brief review, I summarize our basic knowledge about different types of isolated neutron stars. I discuss radio pulsars, central compact objects in supernova remnants, magnetars, nearby cooling neutron stars (also known as the magnificent seven ...

Tumor‐Regional Immune Microenvironment: A Critical Factor in the Design of Radiotherapy–Immunotherapy Combination Trials

open access: yesInternational Journal of Cancer, Volume 159, Issue 8, Page 1857-1872, 15 October 2026.
ABSTRACT Clinical trials combining radiotherapy (RT) with immune checkpoint blockade (ICB) have shown improved outcomes in only a fraction of patients, and optimal strategies for integrating these modalities remain under intense investigation. With a few exceptions, phase III combination trials have yielded disappointing results.

Iron‐Substituted Zn‐Al LDH‐Derived Mixed Oxides: Tailoring Structure, Composition and Redox Properties for Efficient CO2‐to‐Olefins Conversion

open access: yesChemCatChem, Volume 18, Issue 15, 14 August 2026.
LDH‐derived Zn‐Fe‐Al mixed oxides exhibited 40% CO2 conversion and 10.6% yield of light olefins. The composition and the properties of the mixed oxides strongly influenced the selectivity of products, while ZnFe2O4 and iron carbide structure promoted the conversion and the selectivity of light olefins.

On the aberration–retardation effects in pulsars

open access: yes, 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
