A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

Advanced Science, Volume 13, Issue 10, 18 February 2026.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Bayesian sensitivity of binary pulsars to ultra-light dark matter [PDF]

Ultra-light dark matter perturbs the orbital motion of binary pulsars, in particular by causing peculiar time variations of a binary\u27s orbital parameters, which then induce variations in the pulses\u27 times-of-arrival.

Binary pulsars studies with multiwavelength sky surveys - I. Companion star identification [PDF]

, 2014
The identification of the stellar companions to binary pulsars is key to studying the evolution of the binary system and how this is influenced by the interactions between the two stars.

Pulse-profile Modeling and Spin–Orbit Alignment in a Suzaku Sample of Accreting X-Ray Binary Pulsars

The Astrophysical Journal
We report pulse-profile modeling of a sample of 23 X-ray binary pulsars observed with the Suzaku X-ray satellite. These pulsars have spin periods ranging from 0.7 to 9400 s, and their X-ray emission is powered by the accretion from their stellar ...

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

Pacing 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 ...

Constraint‐Aware Operating‐Point Selection for FAST Pulsar Candidate Screening

Advances in Astronomy, Volume 2026, Issue 1, 2026.
FAST pulsar surveys generate candidate volumes that make manual review a practical bottleneck, so fixed‐threshold classification is often mismatched to deployment under limited review budgets. We formulate candidate screening as a constrained operating‐point selection problem: given model scores, the decision threshold is chosen to maximise recall ...

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion

The Astrophysical Journal, 2023
Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

Leveraging Compressed Sensing and Radiomics for Robust Feature Selection for Outcome Prediction in Personalized Ultra‐Fractionated Stereotactic Adaptive Radiotherapy

Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.
A compressed sensing (CS)‐based feature selection method is proposed to select the most informative elements in the radiomic features extracted from medical images of personalized ultra‐fractionated stereotactic adaptive treatment. The CS‐based approach is able to simplify the feature selection process and enhance the accuracy and robustness of a ...

Millisecond Pulsars in M2: New Discoveries and a Detailed Timing Analysis

The Astrophysical Journal
Globular clusters (GCs) offer a unique environment for discovering and studying millisecond pulsars. In this paper, we present a multiepoch search and detailed timing analysis of millisecond pulsars in the GC M2, using the Five-hundred-meter Aperture ...
