Hydrogen is efficiently released during water dissociation on zirconium (Zr), while even very rapid temperature programmed heating of a hydrogen covered Zr surface predominantly leads to dissolution (approximately 99% dissolution). To help resolve these apparently contradictory observations, we have studied the dynamics of water (D2O) dissociation on a crystalline Zr surface by probing the rota...

Self-normalized processes arise naturally in statistical applications. Being unit free, they are not affected by scale changes. Moreover, selfnormalization often eliminates or weakens moment assumptions. In this paper we present several exponential and moment inequalities, particularly those related to laws of the iterated logarithm, for self-normalized random variables including martingales. T...

Abstract We present a comprehensive investigation of main-sequence binaries in the DRAGON simulations, which are first one-million-particle direct N -body simulations globular clusters. analyze orbital parameters binary samples two D1-R7-IMF93 and D2-R7-IMF01, focusing on their secular evolution correlations up to 12 Gyr. These models have different initial stellar mass functions: Kroupa 1993 (...

We study the limiting spectral distribution of large-dimensional sample covariance matrices associated with order-d symmetric random tensors formed by products d variables chosen from n independent standardized variables. find optimal sufficient conditions for this to be Marchenko-Pastur law in case d=d(n) and n→∞. Our reduce d2=o(n) when have uniformly bounded fourth moments. The proofs are ba...

Linearised fluctuating hydrodynamics describes effectively the concentration non-equilibrium fluctuations (NEF) arising during a diffusion process driven by a small concentration gradient. However, fluctuations in the presence of large gradients are not yet fully understood. Here we study the giant concentration NEF arising when a dense aqueous colloidal suspension is allowed to diffuse into an...

We find an l = 2 shape resonance fingerprinted in the angular distribution of cold (∼1 K) Δj rotationally inelastic collision D2 with He a single supersonic expansion. The Stark-induced adiabatic Raman passage is used to prepare (v 2, j 2) rovibrational level control spatial bond axis molecule by magnetic sublevel selection. show that rate D2–D2 relaxation nearly two orders magnitude weaker tha...

Abstract. We study models of continuous-time, symmetric, Z-valued random walks in random environments, driven by a field of i.i.d. random nearest-neighbor conductances ωxy ∈ [0, 1] with a power law with an exponent γ near 0. We are interested in estimating the quenched decay of the return probability P t ω(0, 0), as t tends to +∞. We show that for γ > d2 , the standard bound turns out to be of ...
