Gamma-ray bursters as sources of cosmic rays [PDF]

open access: yes, 1995
The little we do know of the physical conditions in gamma-ray bursters makes them conducive to the acceleration of high-energy cosmic rays, especially if they are at cosmological distances.

Pion mass splitting and phase structure in Twisted Mass QCD

open access: yes, 2004
In the framework of Wilson Chiral Perturbation Theory, we study the effect induced by a twisted Wilson term, as it appears in Twisted Mass QCD (with 2 degenerate quarks). In particular we consider the vacuum orientation and the pion masses.

From the Judaean Desert to the Great Sea : Qumran in a Mediterranean context [PDF]

open access: yes, 2017
The time when Qumran was studied in splendid isolation is long gone, but much work remains to be done when it comes to situating the site in its wider context.

The Arrival of Fast Internet and Employment in Africa

open access: yesThe American Economic Review, 2019
To show how fast Internet affects employment in Africa, we exploit the gradual arrival of submarine Internet cables on the coast and maps of the terrestrial cable network. Robust difference-in-differences estimates from 3 datasets, covering 12 countries,

The First Simultaneous 3.5 and 1.3mm Polarimetric Survey of Active Galactic Nuclei in the Northern Sky

open access: yes, 2014
Short millimeter observations of radio-loud AGN offer the opportunity to study the physics of their inner relativistic jets, from where the bulk millimeter emission is radiated.

Batch-Incremental Learning for Mining Data Streams [PDF]

open access: yes, 2004
The data stream model for data mining places harsh restrictions on a learning algorithm. First, a model must be induced incrementally. Second, processing time for instances must keep up with their speed of arrival.

Lipid Pocket Binders Impose Allosteric Changes of Protein Dynamics Around the Active Site of the Protein Kinase p38α

open access: yesAngewandte Chemie International Edition, EarlyView.
Used in search of novel allosteric sites in the serine/threonine kinase p38α, NMR spectroscopy reveals a dynamic coupling between the catalytic and lipid pockets. The findings uncover a motional interdependence that links distant regions of the enzyme, highlighting the lipid pocket as a promising site for allosteric intervention.

Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

open access: yes, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.

Efficacy of Der f 2/Zen 1‐LAMP1 Plasmid‐Based Vaccine Immunotherapy in Dogs With Atopic Dermatitis: A Proof‐of‐Concept Study

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 306-318, April 2026.
Background: DNA‐based vaccination rapidly induces strong cellular and humoral immune responses, which may be enhanced by inclusion of lysosomal‐associated membrane protein‐1 (LAMP). Objectives: This proof‐of‐concept study evaluated the efficacy and safety of a Der f 2/Zen 1‐LAMP‐based DNA vaccine immunotherapy in client‐owned dogs with nonseasonal AD ...
