Electron Density Structure Measurements With Scattered Intense Laser Beam

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.

The Characteristics of (Normal) Pulsars [PDF]

open access: yes, 2002
Pulsars have now been studied for 34 years. We know of the existence of some 1500 objects at radio frequencies. Many of the characteristics of pulsars such as pulsar period, period derivative, spectrum, polarization, etc., have been catalogued for many ...

The LOFAR pilot surveys for pulsars and fast radio transients [PDF]

open access: yes, 2014
We have conducted two pilot surveys for radio pulsars and fast transients with the Low-Frequency Array (LOFAR) around 140 MHz and here report on the first low-frequency fast-radio burst limit and the discovery of two new pulsars.

The Kinematics of Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1985
Pulsars have a galactic radial distribution similar to that of many galactic populations such as HII regions, massive stars and supernova remnants. However they are generally much further from the plane of the Galaxy than these objects. Proper motion measurements sho that this is because they are typically moving with high velocities.

Interventional therapies for chronic heart failure: An overview of recent developments

open access: yesESC 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 ...

Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT

open access: yes, 2009
Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until recently, only seven were observed to pulse in gamma rays and these were ...

A Perspective of Multi‐Reflecting TOF MS

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

Wide radio beams from gamma-ray pulsars

open access: yes, 2010
We investigate the radio and gamma-ray beaming properties of normal and millisecond pulsars by selecting two samples from the known populations. The first, Sample G, contains pulsars which are detectable in blind searches of gamma-ray data from the Fermi
