Dynamical Crossover in Hot Dense Water: The Hydrogen Bond Role

Philippe Gillet, Livia Eleonora Bove Kado, Umbertoluca Ranieri

We investigate the terahertz dynamics of liquid H2O as a function of pressure along the 450 K isotherm, by coupled quasielastic neutron scattering and inelastic X-ray scattering experiments. The pressure dependence of the single molecule dynamics is anomal ...

Valproic acid potentiates the anticancer activity of capecitabine <i>in vitro</i> and <i>in vivo</i> in breast cancer models via induction of thymidine phosphorylase expression

The prognosis of patients with metastatic breast cancer remains poor, and thus novel therapeutic approaches are needed. Capecitabine, which is commonly used for metastatic breast cancer in different settings, is an inactive prodrug that takes advantage of ...

Pressure dependence of the magnetic order in CrAs: A neutron diffraction investigation

Henrik Moodysson Rønnow, Jonathan White, Peter Babkevich

The suppression of magnetic order with pressure concomitant with the appearance of pressure-induced superconductivity was recently discovered in CrAs. Here we present a neutron diffraction study of the pressure evolution of the helimagnetic ground state to ...

Femtosecond-laser hyperdoping silicon in an SF6 atmosphere: Dopant incorporation mechanism

Tobias Schneider, Silvija Gradecak

In this paper, we examine the fundamental processes that occur during femtosecond-laser hyperdoping of silicon with a gas-phase dopant precursor. We probe the dopant concentration profile as a function of the number of laser pulses and pressure of the dopa ...

Statistics for brain connectomics revisited by two-step procedures

Dimitri Nestor Alice Van De Ville, Djalel Eddine Meskaldji

State-of-the-art neuroimaging data provides several ways today to construct "brain connectomics" based on structural and functional measures. Connection-wise statistical assessment suffers from the large amount of multiple comparisons and is suboptimal as ...

Heavy-tail Phenomena: Spatio-temporal Extremal Dependence

Thomas Lugrin

Heavy-tail phenomena are common in real-life data; the finance and insurance industries, telecommunications, and environment-related events offer typical examples of such phenomena. We focus on the particular topic of the extremogram, for which Davis and M ...

Femtosecond Dynamics of Momentum-Dependent Magnetic Excitations from Resonant Inelastic X-Ray Scattering in CaCu2O3

Thorsten Schmitt

Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic electronic excitations can be probed by direct resonant inelastic x-ray scattering (RIXS). To this end, we isolate the cont ...

Pressure tuning the Fermi level through the Dirac point of giant Rashba semiconductor BiTeI

Helmuth Berger

We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeI under applied pressures up to similar to 2GPa. We observe one high frequency oscillation at all pressures and one low frequency oscillation that emerges betwee ...

Mice with ablated adult brain neurogenesis are not impaired in antidepressant response to chronic fluoxetine

Maria del Carmen Sandi Perez

The neurogenesis hypothesis of major depression has two main facets. One states that the illness results from decreased neurogenesis while the other claims that the very functioning of antidepressants depends on increased neurogenesis. In order to verify t ...

Peculiarities in the pressure dependence of photoluminescence in InAlN

Nicolas Grandjean, Jean-François Carlin

Studies of ambient-pressure and high-pressure behavior of photoluminescence (PL) for series of InxAl1-xN layers are presented. The measured evolution of PL energy (E-PL) with x is characterized by a clear decrease of E-PL and exhibits a strong bowing. This ...
