Lessons from HAWC pulsar wind nebulae observations: The diffusion constant is not a constant; pulsars remain the likeliest sources of the anomalous positron fraction; cosmic rays are trapped for long periods of time in pockets of inefficient diffusion [PDF]

open access: yesPhysical Review D, 2018
Author(s): Profumo, Stefano; Reynoso-Cordova, Javier; Kaaz, Nicholas; Silverman, Maya | Abstract: Recent TeV observations of nearby pulsars with the HAWC telescope have been interpreted as evidence that the diffusion of high-energy electrons and ...

Preserved Thermoregulation in Huntington's Disease: Insights from an Observational Case–Control Study

open access: yesMovement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Thermoregulation is critical for preventing hyperthermia during physical activity. In Huntington's disease (HD), research on possible thermoregulatory alterations has received little attention. Objectives We aimed to investigate and compare skin temperature differences before and after exercise between HD patients and healthy ...

X-ray emission from PSR J1809-1917 and its pulsar wind nebula, possibly associated with the TeV gamma-ray source HESS J1809-193

open access: yes, 2007
We detected X-ray emission from the 50-kyr-old pulsar J1809-1917 and resolved its pulsar wind nebula (PWN) with Chandra. The pulsar spectrum fits PL+BB model with the photon index of 1.2 and the BB temperature of 2 MK for n_{H}=0.7\times 10^{22} cm^{-2}.

Recent Advancements in the Treatment of Age‐Related Macular Degeneration

open access: yesMed Research, EarlyView.
ABSTRACT Age‐related macular degeneration (AMD) is a prevalent cause of visual impairment and blindness among the elderly. AMD can be categorized into two subtypes: “wet” and “dry.” Current treatments for wet AMD mainly involve anti‐vascular endothelial growth factor (VEGF) drugs, and there are three U.S.

Pulsar Searches with the SKA [PDF]

open access: yes, 2017
The Square Kilometre Array will be an amazing instrument for pulsar astronomy. While the full SKA will be sensitive enough to detect all pulsars in the Galaxy visible from Earth, already with SKA1, pulsar searches will discover enough pulsars to increase

Pulsar-candidate Selection Using a Generative Adversarial Network and ResNeXt

open access: yesThe Astrophysical Journal Supplement Series, 2022
Pulsar research has been a hot topic in the area of astronomy since they were first discovered. Pulsar discovery is fundamental for pulsar research. While pulsars are now visible across the electromagnetic spectrum, pulsar searches with modern radio ...

Deriving birth timing of roe deer fawns from body measurements to limit mowing mortality

open access: yesWildlife Biology, EarlyView.
Every spring, hiding roe deer fawns Capreolus capreolus in meadows are injured or killed by mowing activities. To assess the temporal overlap between mowing activities and the fawning period, and thus help reduce the risk of mowing death, we have determined the average parturition date in three regions of Bavaria, southern Germany.

Selection of radio pulsar candidates using artificial neural networks

open access: yes, 2010
Radio pulsar surveys are producing many more pulsar candidates than can be inspected by human experts in a practical length of time. Here we present a technique to automatically identify credible pulsar candidates from pulsar surveys using an artificial ...

The population of TeV pulsar wind nebulae in the H.E.S.S. Galactic Plane Survey [PDF]

open access: yes, 2017
The nine-year H.E.S.S. Galactic Plane Survey (HGPS) yielded the most uniform observation scan of the inner Milky Way in the TeV gamma-ray band to date.
