Characterising the response of an International LOFAR Station

The Open Journal of Astrophysics
Phased-array radio interferometers with fixed antennas are a highly scalable design which can achieve a large gain. However they are complex systems and challenging to calibrate.

Aspect Detection Model

This page contains the files necessary to use the aspect detection model from Park, Greene, and Colaresi (2020) for prediction. PULSAR uses this model to help predict which aspects of human rights a given sentence concerns.

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

Carbon Energy, Volume 8, Issue 6, June 2026.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.

The Bursting Pulsar GRO J1744−28: the slowest transitional pulsar?

, 2018
GRO J1744-28 (the Bursting Pulsar) is a neutron star low-mass X-ray binary which shows highly structured X-ray variability near the end of its X-ray outbursts.

DAMP Laden Extracellular Vesicles From the Airways of Patients With Severe SARS‐CoV‐2 Respiratory Infection Compromise Inflammation and Cellular Metabolism

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
Extracellular vesicles from severe COVID‐19 airways carry depleted miRNAs and elevated DAMPs, reprogramming monocytes toward senescence, impaired metabolism, and predominantly reduced cytokine responses. However, they drive excess IL‐8 production, amplifying neutrophil recruitment and dysfunctional inflammation across the respiratory tract.

Proteomic and Super‐Resolution Analyses of Murine Brown Adipocyte‐Derived Extracellular Vesicles

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
Graphical Abstract ABSTRACT Thermogenic brown adipocytes (BAs) are not only an energy sink but also regulate systemic metabolic health through secreted factors and extracellular vesicles (EVs). Here, we investigate the baseline profiles BA‐EVs and how cold‐induced thermogenesis alters the proteome of BA‐EVs.

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]

, 2011
We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

Pulsar nebulae

, 2011
[[abstract]]Several `exotic' supernova remnants are re-interpreted as pulsar-illuminated former wind-zones. The class of supernova remnants thus splits into (i) (the usual) `shell remnants' and (ii) `pulsar nebulae' in which a (fairly young) pulsar blows

A Perspective of Multi‐Reflecting TOF MS

Mass Spectrometry Reviews, Volume 45, Issue 3, Page 476-506, May/June 2026.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.
