Vigorous atmospheric motion in the red supergiant star Antares

open access: yes, 2017
Red supergiant stars represent a late stage of the evolution of stars more massive than about nine solar masses, in which they develop complex, multi-component atmospheres.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Towards Personally Relevant Navigation: The Differential Effects of Cognitive Style and Map Orientation on Spatial Knowledge Development

open access: yesApplied Sciences
Under emergencies such as floods and fires or during indoor navigation where cues from local landmarks and a Global Positioning System (GPS) are no longer available, the acquisition of comprehensive environmental representation becomes particularly ...

Beam Optics Modeling at Cps Extraction Throughout A Nonlinear fringe field [PDF]

open access: yes, 1997
An accurate optics model of the CPS ring in the extraction region, where the lateral fringe field is highly non-linear, is of importance for transverse emittance preservation of beams for the future LHC.

Feasibility of the Spin-Light Polarimetry Technique for Longitudinally Polarized Electron Beams

open access: yes, 2013
A novel polarimeter based on the asymmetry in the spacial distribution of synchrotron radiation will make for a fine addition to the existing M{\o}ller and Compton polarimeters.

Detectors for leptonic CP violation at the neutrino factory [PDF]

open access: yes, 2011
Studies carried out in the framework of the International Design Study for the Neutrino Factory (the IDS-NF) show that the sensitivity to the CP violating phase and the last unknown mixing angle θ13 is maximised when two far detectors optimized to detect

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Overestimation of thermal emittance in solenoid scans due to coupled transverse motion

open access: yes, 2018
The solenoid scan is a widely used method for the in-situ measurement of the thermal emittance in a photocathode gun. The popularity of this method is due to its simplicity and convenience since all rf photocathode guns are equipped with an emittance ...

Field Driven Thermostated System : A Non-Linear Multi-Baker Map [PDF]

open access: yes, 1998
In this paper, we discuss a simple model for a field driven, thermostated random walk that is constructed by a suitable generalization of a multi-baker map.

Wide Field Mapping of 5C12 [PDF]

open access: yesInternational Astronomical Union Colloquium, 1991
AbstractThe existing method of producing radio maps from interferometric data set is based on the assumption that there is a two dimensional fourier transform relationship between the sky brightness and the measured visibility. In mapping of a very wide field, this basic assumption breaks down due to various practical problems, e.g. bandwidth smearing.
