Profile instabilities of the millisecond pulsar PSR J1022+1001 [PDF]
, 1999 We present evidence that the integrated profiles of some millisecond pulsars exhibit severe changes that are inconsistent with the moding phenomenon as known from slowly rotating pulsars.

Advanced Science, EarlyView.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 ...

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars
The Astrophysical Journal, 2023 We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

Enhancing CHO cell recombinant protein production using a perfusion‐directed host evolution approach
Biotechnology Progress, EarlyView.Abstract Clonally derived cell lines generated from Chinese hamster ovary (CHO) cells encounter numerous stressors when cultured in high‐intensity perfusion bioreactors leading to poor process performance. To circumvent this, the ability of CHO cells to adapt to different culture environments was exploited. Here host cells were selected in the presence

Binary system delays and timing noise in searches for gravitational waves from known pulsars [PDF]
, 2007 The majority of fast millisecond pulsars are in binary systems, so that any periodic signal they emit is modulated by both Doppler and relativistic effects.

Interventional therapies for chronic heart failure: An overview of recent developments
ESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...

A Method to Estimate the Cooling Time of Ultra-Relativistic Electrons in Pulsar Wind Nebulae [PDF]
American Journal of Astronomy and Astrophysics, 2015 Pulsar is a highly magnetized rotating neutron star. It continuously emits a wind of relativistic electrons and positrons. This wind creates an electron-positron-cloud around the pulsar. This cloud, which is full of relativistic electrons and positrons, is called a Pulsar Wind Nebula (PWN).

Pulse Profile Variability of PSR J1022+1001 in NANOGrav Data
The Astrophysical JournalPulse profile stability is a central assumption of standard pulsar timing methods. Thus, it is important for pulsar timing array experiments such as the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) to account for any pulse ...

Observations of microglitches in HartRAO radio pulsars [PDF]
, 2010 A detailed observation of microglitch phenomenon in relatively slow radio pulsars is presented. Our analyses for these small amplitude jumps in pulse rotation frequency ($\nu$) and/or spin down rate ($\dot{\nu}$) combine the traditional manual detection ...
