From Be X-Ray Binaries to Double Neutron Stars: Exploring the Spin and Orbital Evolution

Universe
We explore the evolutionary link between Galactic Be X-ray binaries (BeXBs) and Galactic field double neutron stars (DNSs) based on the properties of the NS spin period—P and binary orbital period—Porb.

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 ...

Pulsar statistics - IV. Pulsar velocities [PDF]

Monthly Notices of the Royal Astronomical Society, 1997
We have used Monte Carlo simulations of the Galactic pulsar population to reassess the kinematics of radio pulsars in light of the large number of recently published proper motions and the revised distance model. Our modelling of the observational selection effects that distort the observed sample is far more detailed and self-consistent than that of ...

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.

Ab-initio Pulsar Magnetosphere: Particle Acceleration in Oblique Rotators and High-energy Emission Modeling [PDF]

, 2017
We perform global particle-in-cell simulations of pulsar magnetospheres, including pair production, ion extraction from the surface, frame-dragging corrections, and high-energy photon emission and propagation. In the case of oblique rotators, the effects

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 ...

Identification of Tumor‐Specific Surface Proteins Enables Quantification of Extracellular Vesicle Subtypes for Early Detection of Pancreatic Ductal Adenocarcinoma

Advanced Science, Volume 12, Issue 21, June 5, 2025.
Pancreatic ductal adenocarcinoma (PDAC) extracellular vesicle (EV) surface protein assay operates via a two‐step workflow – Step 1: Click chemistry‐mediated enrichment of PDAC EVs by EV Click Beads, in the presence of one of the three trans‐cyclooctene‐grafted PDAC EV‐specific antibodies; Step 2: Quantification of the enriched PDAC EVs by reverse ...
