Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

open access: yesAdvanced Electronic Materials, Volume 12, Issue 20, 26 October 2026.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

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

Mode Changing in PSR B0844-35 and PSR B1758-29 with Enhanced Emission at the Profile Centers

open access: yesThe Astrophysical Journal, 2023
We have studied the single pulse emission from two pulsars, PSR B0844-35 and PSR B1758-29, over a wide frequency range of 300–750 MHz using the upgraded Giant Metrewave Radio Telescope.

Multi‐omics–driven precision medicine

open access: yesiMeta, Volume 5, Issue 5, October 2026.
Multi‐omics‐driven precision medicine (MODPM) provides a multiscale, continuously learnable framework that integrates genomics, epigenomics, transcriptomics, proteomics, metabolomics, microbiome profiles, and clinical data. Powered by artificial intelligence and foundation models, MODPM enables cross‐modal representation learning, contextual modeling ...

Radio pulsars [PDF]

open access: yes, 2004
This thesis focuses on different aspects of radio pulsars: on the one hand it describes research on the pulsar emission mechanism (nulling, drifting subpulses, single-pulse polarisation and their mutual interaction).

Gravity Tests with Radio Pulsars

open access: yesUniverse, 2020
The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion ...

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 ...

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

open access: yesThe Journal of Physiology, Volume 604, Issue 20, Page 8501-8522, 15 October 2026.
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

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, Volume 50, Issue 3, September 2026.
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.

Search for radio pulsations in four anomalous X-ray pulsars and discovery of two new pulsars [PDF]

open access: yes, 2006
We report on observations of four southern Anomalous X-ray Pulsars (1RXSJ170849.0-400910, 1E1048.1-5937, 1E1841-045 and AXJ1845-0258) obtained at 1.4 GHz using the Parkes Radio Telescope.
