Pulsar observations with the Fermi LAT: what we have seen [PDF]

arXiv, 2009
A year after \emph{Fermi} was launched, the number of known gamma-ray pulsars has increased dramatically. For the first time, a sizable population of pulsars has been discovered in gamma-ray data alone. For the first time, millisecond pulsars have been confirmed as powerful sources of gamma-ray emission, and a whole population of these objects is seen ...

Association of impaired olfactory identification with prevalent mild cognitive impairment and regional brain atrophy: the Hisayama Study

Psychiatry and Clinical Neurosciences, EarlyView.
Aim To investigate the association of olfactory identification ability with both the prevalence of mild cognitive impairment (MCI) and regional brain atrophy in a community‐dwelling older population. Methods A total of 1293 participants without dementia aged 65 years or older underwent a Japanese version of the 4‐Item Pocket Smell Test, an assessment ...

Comprehensive Measurement of Position and Velocity in the Transverse Direction Using the Crab Pulsar

Aerospace
Traditional X-ray pulsar ranging and velocity measurement methods only estimate the radial position and velocity information of the pulsar. For non-linear orbits, errors in the transverse position and velocity of the pulsar lead to errors in the radial ...

FINE STRUCTURE OF ANOMALOUSLY INTENSE PULSES OF PSR J0814+7429 RADIO EMISSION IN THE DECAMETER RANGE

Radio Physics and Radio Astronomy, 2017
Purpose: The fine structure of the anomalously intense pulses of PSR J0814+7429 (В0809+74) has been studied. The pulsar radio emission fine structure is investigated to determine its parameters in the lowest part of spectrum available for groundbased ...

Three-dimensional Analytical Description of Magnetised Winds from Oblique Pulsars [PDF]

, 2015
Rotating neutron stars, or pulsars, are plausibly the source of power behind many astrophysical systems, such as gamma-ray bursts, supernovae, pulsar wind nebulae and supernova remnants. In the past several years, 3D numerical simulations made it possible to compute pulsar spindown luminosity from first principles and revealed that oblique pulsar winds

The Aging Substantia Nigra is Characterized by ROS Accumulation Potentially Resulting in Increased Neuroinflammation and Cytoskeletal Remodeling

Advanced Biology, Volume 9, Issue 4, April 2025.
Definition of study groups, including young individuals (n = 7 mean age: 28.7 years), middle aged individuals (n = 14 mean age: 62.3 years) and elderly individuals (n = 14 mean age: 83.9 years). Condensed workflow including sample preparation (sample lysis and tryptic digestion), mass spectrometric measurements and subsequent data and statistical ...

Fast Butterfly Epoch Folding-Based X-Ray Pulsar Period Estimation With a Few Distorted Profiles

IEEE Access, 2020
The traditional pulsar period estimation method using a single distorted profile averts multiple epoch folding processes, but still has space for accuracy to improve.

Discovery of Eight Recycled Pulsars - The Swinburne Intermediate Latitude Pulsar Survey [PDF]

arXiv, 1999
We have conducted a pulsar survey of intermediate Galactic latitudes (15deg < |b| < 5deg) at 20 cm. The survey has been highly successful, discovering 58 new pulsars, eight of which are recycled, in only ~14 days of integration time. One pulsar has a very narrow (2deg FWHM) average profile for the pulsar's period (278 ms).
