Internal Heating of Old Neutron Stars: Contrasting Different Mechanisms

, 2010
Context: The standard cooling models of neutron stars predict temperatures $T10^{7}$ yr. However, the likely thermal emission detected from the millisecond pulsar J0437-4715, of spin-down age $t_s \sim 7\times10^9$ yr, implies a temperature $T\sim 10^5 ...

On the galactic distributions of radio pulsars and plasma density [PDF]

Serbian Astronomical Journal, 2016
A brief review of distance measurement methods for some astronomical sources is presented. Galactic plasma density distribution as related to the distribution of radio pulsars is discussed and a method for constructing relations between ...

Detecting Pulsars with Interstellar Scintillation in Variance Images

, 2016
Pulsars are the only cosmic radio sources known to be sufficiently compact to show diffractive interstellar scintillations. Images of the variance of radio signals in both time and frequency can be used to detect pulsars in large-scale continuum surveys ...

CXCL10 Promotes Spinal Macrophage Recruitment via the JAK/STAT3 Pathway to Induce Pain in Experimental Autoimmune Prostatitis

Cell Proliferation, Volume 58, Issue 4, April 2025.
The CXCL10/CXCR3 axis was involved in spinal macrophage infiltration through activating the JAK/STAT3 pathway. The prostate NGF/TrKA axis was involved in the neuroinflammation and pain in chronic prostatitis, and inhibition of NGF could attenuate pain response in chronic prostatitis, which provided novel therapeutic targets for pain treatment in ...

Testing Gravity with Pulsars in the SKA Era [PDF]

, 2014
The Square Kilometre Array (SKA) will use pulsars to enable precise measurements of strong gravity effects in pulsar systems, which yield tests of gravitational theories that cannot be carried out anywhere else.

Transcriptomic and Proteomic Response to Grain Filling Reveal Potential Grain Size Regulation Mechanisms in Quinoa (Chenopodium quinoa Willd)

Plant Breeding, EarlyView.
ABSTRACT Grain size is an important factor affecting quinoa yield, and studying the molecular mechanism of quinoa grain size formation is of great significance for cultivar selection. In this study, we analysed phenotypic traits, conducted RNA sequencing and proteomic detection during grain filling in different developmental stages.

Efficiency of Nonthermal Pulsed Emission from Eight MeV Pulsars

The Astrophysical Journal
We report on the properties of pulsed X-ray emission from eight MeV pulsars using XMM-Newton, NICER, NuSTAR, and HXMT data. For five of the eight MeV pulsars, the X-ray spectra can be fit by a broken power-law model with a break energy of ∼5–10 keV.

A survey of nulling pulsars using the Giant Meterwave Radio Telescope

, 2012
Several pulsars show sudden cessation of pulsed emission, which is known as pulsar nulling. In this paper, the nulling behaviour of 15 pulsars is presented.

The application of co-integration theory in ensemble pulsar timescale algorithm [PDF]

, 2019
Employing multiple pulsars and using an appropriate algorithm to establish ensemble pulsar timescale can reduce the influences of various noises on the long-term stability of pulsar timescale, compared to a single pulsar. However, due to the low timing precision and the significant red noises of some pulsars, their participation in the construction of ...
