RELATIVISTIC SPIN-PRECESSION IN BINARY PULSARS [PDF]

The Twelfth Marcel Grossmann Meeting, 2012
After the first prediction to expect geodetic precession in binary pulsars in 1974, made immediately after the discovery of a pulsar with a companion, the effects of relativistic spin precession have now been detected in all binary systems where the magnitude of the precession rate is expected to be sufficiently high.

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters

The Astrophysical Journal
Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.

The Green Bank North Celestial Cap Survey. VIII. 21 New Pulsar Timing Solutions

The Astrophysical Journal, 2023
We present timing solutions for 21 pulsars discovered in 350 MHz surveys using the Green Bank Telescope (GBT). All were discovered in the Green Bank North Celestial Cap pulsar survey, with the exception of PSR J0957−0619, which was found in the GBT 350 ...

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection

Space Weather, Volume 24, Issue 4, April 2026.
Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.

A Radio Pulsar/X-ray Binary Link [PDF]

Science, 2009
From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased by long-lasting mass transfer from their companion stars. Using data from a radio pulsar survey, Archibald

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

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 ...

Overcoming the Challenges of Transmural Durable Lesions With PFA—Impact of Electrode Design and Contact Assessment

Pacing and Clinical Electrophysiology, Volume 49, Issue 1, Page 25-31, January 2026.
Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

The Intrabinary Shock and Companion Star of Redback Pulsar J2215+5135

The Astrophysical Journal
PSR J2215+5135 (J2215) is a “redback” spider pulsar, where the intrabinary shock (IBS) wraps around the pulsar rather than the stellar-mass companion. Spider orbital light curves are modulated, dominated by their binary companion thermal emission in the ...

Constraint‐Aware Operating‐Point Selection for FAST Pulsar Candidate Screening

Advances in Astronomy, Volume 2026, Issue 1, 2026.
FAST pulsar surveys generate candidate volumes that make manual review a practical bottleneck, so fixed‐threshold classification is often mismatched to deployment under limited review budgets. We formulate candidate screening as a constrained operating‐point selection problem: given model scores, the decision threshold is chosen to maximise recall ...
