Orbital modulation of emission of the binary pulsar J0737-3039B

, 2005
In binary radio pulsar system J0737-3039, slow pulsar B shows orbital modulations of intensity, being especially bright at two short orbital phases. We propose that these modulations are due to distortion of pulsar B magnetosphere by pulsar A wind which ...

Detection and localization of continuous gravitational waves with pulsar timing arrays: the role of pulsar terms [PDF]

, 2016
A pulsar timing array is a Galactic-scale detector of nanohertz gravitational waves (GWs). Its target signals contain two components: the `Earth term' and the `pulsar term' corresponding to GWs incident on the Earth and pulsar respectively.

Comparing Recent Pulsar Timing Array Results on the Nanohertz Stochastic Gravitational-wave Background

Astrophysical Journal
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohertz gravitational-wave background (GWB).

Radio emission from a pulsar’s magnetic pole revealed by general relativity [PDF]

Science, 2019
General relativity reveals pulsar beams Pulsars are rotating neutron stars that emit beams of radio waves along their magnetic poles, seen as regular pulses if the beam points toward Earth. Desvignes et al.

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

Advanced Science, EarlyView.
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 ...

Fifty years of pulsar candidate selection: from simple filters to a new principled real-time classification approach [PDF]

Monthly notices of the Royal Astronomical Society, 2016
Improving survey specifications are causing an exponential rise in pulsar candidate numbers and data volumes. We study the candidate filters used to mitigate these problems during the past fifty years.

Single‐Position Peptide Clustering for Peptidomics Reveals Novel Disease Biomarkers and Dysregulated Proteolytic Characteristics

Advanced Science, EarlyView.
A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...
