Research on establishing a joint time-scale of pulsar time and atomic time based on a wavelet analysis method

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Pulsar time has different physical mechanisms from atomic time, and these two time-scales are complementary in terms of stability performance. The joint timekeeping of pulsar and atomic time is currently an important application direction.

A Bayesian method for pulsar template generation

open access: yes, 2015
Extracting Times of Arrival from pulsar radio signals depends on the knowledge of the pulsars pulse profile and how this template is generated. We examine pulsar template generation with Bayesian methods.

Multi‐scale maternal behavioral responses by white‐tailed deer to coyote predation risk

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
In the piedmont region of the southeastern US, white‐tailed deer adjust maternal care strategies in response to variation in risk of encountering coyotes. In areas frequented by coyotes, adult female deer (i.e., does) increase their use of space, likely to avoid drawing coyotes to the location where a fawn is hidden.

Sotatercept in Pulmonary Langerhans Cell Histiocytosis‐Associated Pulmonary Hypertension: A Case Series and Systematic Review

open access: yesPulmonary Circulation, Volume 16, Issue 1, January 2026.
ABSTRACT Pulmonary Langerhans cell histiocytosis (PLCH) frequently complicated by pulmonary hypertension (PH), which markedly worsens prognosis. We retrospectively reviewed three institutional PLCH‐PH cases treated with off‐label Sotatercept added to background triple therapy and performed a systematic review of published PLCH‐PH reports (PubMed/Embase

In-field Phasing at the Upgraded GMRT

open access: yesThe Astrophysical Journal
In time-domain radio astronomy with arrays, voltages from individual antennas are added together with proper delay and fringe correction to form the beam in real time.

A Pulsar Time Scale Based on Parkes Observations in 1995--2010

open access: yes, 2018
Timing of highly stable millisecond pulsars provides the possibility of independently verifying terrestrial time scales on intervals longer than a year. An ensemble pulsar time scale is constructed based on pulsar timing data obtained on the 64-m Parkes ...

Overcoming the Challenges of Transmural Durable Lesions With PFA—Impact of Electrode Design and Contact Assessment

open access: yesPacing and Clinical Electrophysiology, Volume 49, Issue 1, Page 25-31, January 2026.
Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

NICER Timing of the X-Ray Thermal Isolated Neutron Star RX J0806.4–4123

open access: yesThe Astrophysical Journal
The X-ray thermal isolated neutron star (XTINS) RX J0806.4–4123 shows interesting multiwavelength properties that seemingly deviate from those of similar neutron stars.

Reprocessing of the Parkes 70 cm Survey and Discovery of a New Radio Pulsar in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal
We have reprocessed the data archived from the Parkes 70 cm (PKS70) pulsar survey with an expanded dispersion measure (DM) search range and an acceleration search.

The NANOGrav 12.5-Year Data Set: Dispersion Measure Misestimations with Varying Bandwidths

open access: yesThe Astrophysical Journal
Noise characterization for pulsar-timing applications accounts for interstellar dispersion by assuming a known frequency dependence of the delay it introduces in the times of arrival (TOAs).
