Towards a test of the weak equivalence principle of gravity using anti-hydrogen at CERN

2016

International audience; The aim of the GBAR (Gravitational Behavior of Antimatter at Rest) experiment is to measure the free fall acceleration of an antihydrogen atom, in the terrestrial gravitational field at CERN and therefore test the Weak Equivalence Principle with antimatter. The aim is to measure the local gravity with a 1% uncertainty which can be reduced to few parts of 10-3.

Female survivors’ experiences of authorities’ actions in cases of partner stalking

2020

Previous studies have shown that civil authorities fail to understand the nature of stalking and the harmful consequences it causes victims. The aim of this study was to investigate how the victims of partner stalking had perceived the actions of civil authorities and the stalking investigation process. The data were drawn from conversations among members of an internet-based peer support group for female victims of partner stalking. We identified four main categories of victims’ experiences pertaining to authorities’ actions and the investigation process: authorities’ problems in dealing with stalking, dissatisfaction with the investigation process, trust in the authorities and expectation…

Cholesterol and Amyloid-β: Evidence for a Cross-Talk between Astrocytes and Neuronal Cells.

2011

Accumulating data supports the concept that alterations of cholesterol metabolism might influence the development of Alzheimer's disease (AD), a neurodegenerative disorder characterized by progressive accumulation of amyloid-β (Aβ) peptides in the brain. Changes in the neuronal production of Aβ have been described as a function of cholesterol levels, thus suggesting a causal link between cholesterol homeostasis dysregulation and AD pathogenesis. Under physiological conditions, cholesterol uptake in the brain is efficiently prevented by the blood-brain barrier, and mature neurons are thought to rely on glial cells for their cholesterol supply. In the present study, we tested the hypothesis t…

Mitochondrial redox signaling: Interaction of mitochondrial reactive oxygen species with other sources of oxidative stress.

2014

Significance: Oxidative stress is a well established hallmark of cardiovascular disease and there is strong evidence for a causal role of reactive oxygen and nitrogen species (RONS) therein. Recent Advances: Improvement of cardiovascular complications by genetic deletion of RONS producing enzymes and overexpression of RONS degrading enzymes proved the involvement of these species in cardiovascular disease at a molecular level. Vice versa, overexpression of RONS producing enzymes as well as deletion of antioxidant enzymes was demonstrated to aggravate cardiovascular complications. Critical Issues: With the present overview we present and discuss different pathways how mitochondrial RONS inte…

High significance measurement of the terrestrial neutrino flux with the Borexino detector

2015

International audience; We review the geoneutrino measurement with Borexino from 2056 days of data taking.

Multiplexing of encrypted data using fractal masks

2012

In this Letter, we present to the best of our knowledge a new all-optical technique for multiple-image encryption and multiplexing, based on fractal encrypting masks. The optical architecture is a joint transform correlator. The multiplexed encrypted data are stored in a photorefractive crystal. The fractal parameters of the key can be easily tuned to lead to a multiplexing operation without cross talk effects. Experimental results that support the potential of the method are presented.

Exploring a regulatory role for mast cells: 'MCregs'?

2010

Regulatory cells can mould the fate of the immune response by direct suppression of specific subsets of effector cells, or by redirecting effectors against invading pathogens and infected or neoplastic cells. These functions have been classically, although not exclusively, ascribed to different subsets of T cells. Recently, mast cells have been shown to regulate physiological and pathological immune responses, and thus to act at the interface between innate and adaptive immunity assuming different functions and behaviors at discrete stages of the immune response. Here, we focus on these poorly defined, and sometimes apparently conflicting, functions of mast cells.

Cheap Talk with Two Audiences: An Experiment

2017

In this paper we experimentally test strategic information transmission between one informed and two uninformed agents in a cheap-talk game. We find evidence of the “disciplining” effect of public communication as compared to private; however, it is much weaker than predicted by the theory. Adding a second receiver naturally increases the complexity of strategic thinking when communication is public. Using the level-k model, we exploit the within subject design to show how individuals decrease their level-k in public communication. Surprisingly, we find that individuals become more sophisticated when they communicate privately with two receivers rather than one.

Extended View Angle Integral Imaging 3D Display using Smart Pseudoscopic-to-orthoscopic Conversion with Head Tracking

2016

We overview a head tracking integral imaging display using the smart pseudoscopic-to-orthoscopic conversion method. The crosstalk for a large viewing angle in integral imaging is eliminated by generating a new set of elemental images.
