Low‐Frequency Raman Spectra of Natural Pyrrhotites: Polarization Dependence for Its Lattice Modes

open access: yesJournal of Raman Spectroscopy, EarlyView.
The present study found low‐wavenumber Raman modes of pyrrhotite Fe1‐xS at ~68, ~87, ~117, and ~230 cm−1 for the first time, thanks to a lab‐built Raman spectrometer, in which the optical path of the incident laser was purged by Ar gas. The sufficiently high signal‐to‐noise and signal‐to‐base ratios enabled us to obtain the polarization dependence of ...

Theoretical challenges in acceleration and transport of ultra high energy cosmic rays: A review

open access: yesEPJ Web of Conferences, 2013
The wealth of data collected in the last few years thanks to the Pierre Auger Observatory and recently to the Telescope Array made the problem of the origin of ultra high energy cosmic rays a genuinely experimental/observational one.

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 ...

Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence

open access: yesThe Astrophysical Journal
While cosmic rays ( E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear.

Galactic cosmic ray propagation models using Picard [PDF]

open access: yesarXiv, 2015
We present results obtained from our newly developed Galactic cosmic-ray transport code PICARD, that solves the cosmic-ray transport equation. This code allows for the computation of cosmic-ray spectra and the resulting gamma-ray emission. Relying on contemporary numerical solvers allows for efficient computation of models with deca-parsec resolution ...

Wilms Tumor in Children with AMER1/WTX Germline Pathogenic Variants: A Multicenter Case Series

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background 10–15% of children with Wilms tumor (WT) have predisposing genetic syndromes. Somatic mutations are frequently identified; however, germline pathogenic variants in AMER1 are much less prevalent and are associated with osteopathia striata with cranial sclerosis (OSCS).
