Longitudinal Surveillance of Influenza A Virus Exposure in Wild Boars (Sus scrofa) in Spain (2015–2023): Serologic and Virologic Evidence of Subtype Infections and H5N1 Spillover Risk

open access: yesZoonoses and Public Health, Volume 73, Issue 3, Page 191-204, May 2026.
ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

Are extragalactic gamma ray bursts the source of the highest energy cosmic rays? [PDF]

open access: yes, 1999
Recent observations with the large air shower arrays of ultra high energy cosmic rays (UHECR) and recent measurements/estimates of the redshifts of gamma ray bursts (GRBs) seem to rule out extragalactic GRBs as the source of the cosmic rays that are ...

No evidence for gamma-ray halos around active galactic nuclei resulting from intergalactic magnetic fields

open access: yes, 2010
We analyze the gamma-ray halo around stacked AGNs reported in Ap.J.Lett., 2010, 722, L39. First, we show that the angular distribution of gamma-rays around the stacked AGNs is consistent with the angular distribution of the gamma-rays around the Crab ...

Universal Entanglement and an Information‐Complete Quantum Theory

open access: yesAdvanced Physics Research, Volume 5, Issue 4, April 2026.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

The Cannonball Model of Gamma Ray Bursts: Lines in the X-Ray Afterglow [PDF]

open access: yes, 2001
Recent observations suggest that gamma-ray bursts (GRBs) and their afterglows are produced by jets of highly relativistic cannonballs (CBs), emitted in supernova explosions. The fully ionized CBs cool to a temperature below 4500 K within a day or two, at

Strong GeV Emission Accompanying TeV Blazar H1426+428

open access: yes, 2003
For High frequency BL Lac objects (HBLs) like H1426+428, a significant fraction of their TeV gamma-rays emitted are likely to be absorbed in interactions with the diffuse IR background, yielding $e^\pm$ pairs.

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

open access: yesPest Management Science, Volume 82, Issue 4, Page 2910-2924, April 2026.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

Arguments against a dominantly hadronic origin of the VHE radiation from the supernova remnant RX J1713-3946

open access: yes, 2007
The flux of photons with energies above 1 TeV from the direction of the centre and a cloud in the western part of the nearby southern supernova remnant (SNR) RX J1713.7-3946 is calculated in the ``hadronic scenario'' that aims to explain the intense VHE ...
