Strongly Lensed Supermassive Black Hole Binaries as Nanohertz Gravitational-wave Sources

The Astrophysical Journal, 2023
Supermassive black hole binary systems (SMBHBs) should be the most powerful sources of gravitational waves (GWs) in the universe. Once pulsar timing arrays (PTAs) detect the stochastic GW background from their cosmic merger history, searching for ...

Multi‐omics predicts radiotherapy response in small cell lung cancer patients receiving whole brain irradiation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Objective Dosiomics and radiomics elaborate the low‐and high‐order features extracted from images to predict clinical outcomes. Whole‐brain radiotherapy (WBRT) has been widely used in patients with diffuse brain metastases of small cell lung cancer (SCLC).

Deep cervical lymphatic–venous anastomosis attenuates cognitive dysfunction and biomarker abnormalities in severe Alzheimer's disease: A prospective single‐arm study

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION This study evaluated the efficacy of deep cervical lymphatic–venous anastomosis (dcLVA) for severe Alzheimer's disease (AD). METHODS A total of 139 severe AD patients undergoing dcLVA were enrolled, and changes in cognitive function and biomarkers were evaluated by comparing preoperative measures with postoperative outcomes over a

Probing the Universe using Pulsar Timing Arrays [PDF]

EPJ Web of Conferences
Supermassive black holes (SMBH), found at the centers of galaxies, have been observed in the early Universe, yet their rapid growth remains an open question.

How to take the interstellar weather with you in pulsar timing analysis [PDF]

, 2013
Here we present a Bayesian method of including discrete measurements of dispersion measure due to the interstellar medium in the direction of a pulsar as prior information in the analysis of that pulsar. We use a simple simulation to show the efficacy of

Effect of high‐intensity interval exercise on metformin pharmacokinetics in healthy men, assessed through a population pharmacokinetic model

British Journal of Pharmacology, Volume 183, Issue 3, Page 438-452, February 2026.
Abstract Background and Purpose Metformin and exercise are first‐line therapies for prediabetes and type 2 diabetes. However, it is unclear whether the combination of metformin and exercise is synergistic or antagonistic. The aim of this study was to investigate the effect of exercise on metformin pharmacokinetics and help clarify the contradictory ...

Methods for calibrating a cesium atomic clock using a pulsar time-scale

Monthly Notices of the Royal Astronomical Society
ABSTRACT Some millisecond pulsars exhibit extremely high rotational stability, which can form a pulsar-based time-scale. We employed a post-correction method to evaluate the feasibility of the pulsar time-scale (PT) as a time reference to calibrate the frequency of cesium clocks getting more accurate time signals.

A Novel Technique for Long-term Timing of Redback Millisecond Pulsars

The Astrophysical Journal
We present timing solutions spanning nearly two decades for five redback (RB) systems found in globular clusters (GCs), created using a novel technique that effectively “isolates” the pulsar. By accurately measuring the time of passage through periastron

Rfi Mitigation Implementation For Pulsar Radioastronomy

, 2010
International audienceThe observation of known pulsars (pulsar timing) or the search for new pulsars can be limited by radio frequency interference (RFI) generated by Telecommunications activity. In this paper we propose several RFI mitigation techniques

Single‐Position Peptide Clustering for Peptidomics Reveals Novel Disease Biomarkers and Dysregulated Proteolytic Characteristics

Advanced Science, Volume 13, Issue 5, 27 January 2026.
A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...
