Pulsar Luminosity Function [PDF]
Rev.Mex.Astron.Astrofis.39:267-274,2003, 2002 We construct and investigate the pulsar luminosity function using the new catalogue which includes data for 1315 radio pulsars. The luminosity functions are constructed for 400 and 1400 MHz separately, and they are compared. Also, the luminosity functions excluding the binary millisecond pulsars and other pulsars with low magnetic fields are ...

Pancreatic Cancer: Pathogenesis and Clinical Studies
MedComm, Volume 6, Issue 4, April 2025.Although the treatment landscape for cancer has evolved rapidly in recent years, progress has stagnated for pancreatic cancer (PC). PC includes multiple types, but pancreatic ductal adenocarcinoma (PDAC) accounts for >90% of cases. This review focuses on the molecular pathogenesis and different treatments for PDAC, hoping to propose future directions ...

The Characteristics of (Normal) Pulsars [PDF]
arXiv, 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 objects. Still we do not know the details of the pulsar emission mechanism.

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 ...

The Birthplaces of Pulsars [PDF]
Symposium - International Astronomical Union, 1974 With the refinement of the estimates of electron density in the Galaxy it is clear that pulsars have z distances away from the galactic plane of a few hundred parsec. There is now a very strong indication that young pulsars lie at small z distances, suggesting that pulsars originate in a small z population and are given velocities of about 100 km s-1 ...

Shanghai Tianma Radio Telescope and Its Role in Pulsar Astronomy
UniverseAfter two phases of on-site construction and testing (2010–2013 and 2013–2017), the Shanghai Tianma Radio Telescope (TMRT) can work well, with efficiencies better than 50% from 1.3 to 50.0 GHz, mainly benefiting from its low-noise cryogenic receivers and

Calculation of radar signals delay to second order in the frame of the General Relativity Theory
ACI Avances en Ciencias e Ingenierías, 2014 From the Schwarzschild metric, the light delay due to a gravitational field is calculated to second order approximation in the gravitational potential. We analize the contribution of the second order terms for strong gravitational fields as the generated

arXiv, 2012 The first pulsar observations were made at Parkes on March 8, 1968, just 13 days after the publication of the discovery paper by Hewish and Bell. Since then, Parkes has become the world's most successful pulsar search machine, discovering nearly two thirds of the known pulsars, among them many highly significant objects.

Particle acceleration in Pulsars and Pulsar Wind Nebulae
, 2022 These notes summarise the contents of the lectures I delivered at the International School of Physics "Enrico Fermi" on "Foundations of Cosmic Ray Astrophysics". The lectures were dealing with the physics of Pulsars and Pulsar Wind Nebulae (PWNe) in the Cosmic Ray (CR) perspective.

Furnishing the Galaxy with Pulsars
AIP Conference Proceedings, 2008 The majority of pulsar population synthesis studies performed to date have focused on isolated pulsar evolution. Those that have incorporated pulsar evolution within binary systems have tended to either treat binary evolution poorly of evolve the pulsar population in an ad-hoc manner.
