Generation of pulsar radio emission [PDF]
International Astronomical Union Colloquium, 2000 Abstract The generation of radio emission from plasma waves excited by two-stream instability in pulsar magnetospheres is considered. Induced scattering transforms the excited longitudinal waves into waves that escape freely in the form of transverse electromagnetic waves.

Tests of General Relativity from Timing the Double Pulsar [PDF]
Science, 2006 The double pulsar system PSR J0737-3039A/B is unique in that both neutron stars are detectable as radio pulsars. They are also known to have much higher mean orbital velocities and accelerations than those of other binary pulsars. The system is therefore a good candidate for testing Einstein's theory of general relativity and alternative ...

General-relativistic force-free pulsar magnetospheres [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Pulsar magnetospheres are shaped by ultra-relativistic electron/positron plasmas flowing in a strong magnetic field and subject to strong gravitational fields. The former induces magnetospheric currents and space charges responsible for the distortion of the electromagnetic field based on pure electrodynamics.

Advanced Science, Volume 13, Issue 9, 13 February 2026.Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.

Testing general relativity with black hole-pulsar binaries
Physical Review D, 2018 Binary pulsars allow us to carry out precision tests of gravity and have placed stringent bounds on a broad class of theories beyond general relativity. Current and future radio telescopes, such as FAST, SKA, and MeerKAT, may find a new astrophysical system, a pulsar orbiting around a black hole, which will provide us a new source for probing gravity ...

Advanced Science, Volume 13, Issue 10, 18 February 2026.This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

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.

Advanced Science, Volume 13, Issue 9, 13 February 2026.The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.Abstract INTRODUCTION This study evaluated the efficacy of deep cervical lymphatic–venous anastomosis (dcLVA) for severe Alzheimer's disease (AD). METHODS A total of 139 severe AD patients undergoing dcLVA were enrolled, and changes in cognitive function and biomarkers were evaluated by comparing preoperative measures with postoperative outcomes over a
