Signatures of photon and axion-like particle mixing in the gamma-ray burst jet [PDF]

open access: yes, 2011
Photons couple to Axion-Like Particles (ALPs) or more generally to any pseudo Nambu-Goldstone boson in the presence of an external electromagnetic field.

Multimode Ytterbium–Aluminosilicate Core Optical Fibre for Amplification and Laser Applications

open access: yesFibers, 2023
Rare-earth-doped optical fibres are widely used in lasers and amplifiers. The incorporation of ytterbium and aluminium oxide in a high doping concentration has led to the fabrication of a multi-mode (MM) optical fibre.

Mechanisms producing different precipitation patterns over north‐eastern Italy: insights from HyMeX‐SOP1 and previous events [PDF]

open access: yes, 2016
During the first HyMeX Special Observation Period (SOP1) field campaign, the target site of north‐eastern Italy (NEI) experienced a large amount of precipitation, locally exceeding the climatological values and distributed among several heavy‐rainfall ...

Alpes

open access: yesAnthropen, 2020
Terre de contrastes, mosaïque de groupes linguistiques et religieux, les Alpes échappent à toute catégorisation trop stricte, tantôt appréhendées comme une unité qui efface les spécificités, tantôt comme un ensemble problématique. L’étude de leur mutation est aujourd’hui centrale, en relation avec le développement de l’espace urbain et des grands axes ...

The photophobic ALP [PDF]

open access: yesJournal of High Energy Physics, 2018
Abstract We explore models and phenomenology of a photophobic axion-like particle (ALP), an axion whose coupling to photons is maximally suppressed without fine-tuning of the underlying parameters. We demonstrate that photophobia can be a natural UV property of ALP models and determine the irreducible coupling of photophobic ALPs ...

Ultrasensitive probing of plasmonic hot electron occupancies

open access: yesNature Communications, 2022
Experimental evidence is given that upon the optical excitation of surface plasmon polaritons, a nonthermal electron population appears in the topmost domain of the plasmonic film directly coupled to the local fields.

Multiregional Satellite Precipitation Products Evaluation over Complex Terrain [PDF]

open access: yes, 2016
An extensive evaluation of nine global-scale high-resolution satellite-based rainfall (SBR) products is performed using a minimum of 6 years (within the period of 2000-13) of reference rainfall data derived from rain gauge networks in nine mountainous ...

Harvesting systems for steep terrain in the Italian Alps: state of the art and future prospects [PDF]

open access: yes, 2016
Steep slope forest operations in Central Europe and in particular in the Alps are strongly related to the adoption of the cable-based harvesting system, even if innovative ground-based harvesting system, even if innovative ground-based harvesting systems

T1 Vertebra Pedicular Osteoid Osteoma: Minimally Invasive Surgical Resection Aided by New Integrated Navigation to 3D Imaging Device

open access: yesCase Reports in Orthopedics, 2019
We hereby describe a minimally invasive resection of a T1 pedicular osteoid osteoma next to the vertebral canal. The patient had an 18-month report of painful radiculopathy.

Status report of the CERN microwave axion experiment [PDF]

open access: yes, 2013
"Light Shining Through the Wall" experiments can probe the existence of "axion like particles" through their weak coupling to photons. We have adapted such an experiment to the microwave regime and constructed the table top apparatus.
