A 350 MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources: Discovery and Timing of 10 Millisecond Pulsars

open access: yesThe Astrophysical Journal
We have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...

Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

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

open access: yesJournal 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).

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

open access: yesAdvanced 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 ...

Discovery and Timing of Four γ-Ray Millisecond Pulsars

open access: yesThe Astrophysical Journal
We discovered four millisecond pulsars (MSPs) in searches of 80 γ -ray sources conducted from 2015 to 2017 with the Murriyang radio telescope of the Parkes Observatory.

On Period and Burst Histories of AXPs and SGRs and the Possible Evolution of these Objects on the P-Pdot Diagram

open access: yes, 2002
In this paper, timing data for all of the anomalous X-ray pulsars and soft gamma repeaters are compiled. Timing properties of these objects are investigated. The effect of bursts of soft gamma repeaters on their period history is investigated. The P-Pdot

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.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie

open access: yesPhysik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

NiCu/Al2O3 Bimetallic Catalysts for Reductive Amination of Polyether 230: Synergistic Effects of Alloy Formation and Amorphous Support Properties

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
The development of efficient and scalable catalysts for polyether amine (PEA) synthesis via reductive amination remains an enduring industrial challenge. In this study, bimetallic NiCu alloys supported on amorphous alumina were rationally designed for the amination of low‐molecular‐weight polyether (PPG‐230).
