The hydrogen tracer diffusion in LiBH4 has been determined by spatially resolved Raman spectroscopy. The measurements give direct evidence of a macroscopic diffusion of BH-4 ions as well as atomic exchange of hydrogen between the anions. An effective trace ...
A daily return reversal measure of liquidity is developed and estimated using a new comprehensive ultra-high frequency data set of foreign exchange rates during the financial crisis period of 2007--2008. The measure captures market participants' perception ...
We present an approach to multi‐stage international portfolio optimization based on the imposition of a linear structure on the recourse decisions. Multiperiod decision problems are traditionally formulated as stochastic programs. Scenario tree based solut ...
We investigate how various treatments of exact exchange affect defect charge transition levels and band edges in hybrid functional schemes for a variety of systems. We distinguish the effects of long-range vs short-range exchange and of local vs nonlocal e ...
We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. In particular, we exploit the increasing correlation between the exchanged values throughout the iterations of t ...
We study whether monetary policy should target the exchange rate in a two-country model with non-atomistic wage setters, non-traded goods and different degrees of exchange- rate pass through. Commitment to an exchange rate target reduces the labor market d ...
A coding scheme for the two-receivers Gaussian broadcast channel (BC) with feedback is proposed. For some asymmetric settings it achieves new rate pairs. Moreover, it achieves prelog 2 when the noises at the two receivers are fully positively correlated an ...
Abstract * Article Structure * Figures and Tables * References Abdominal aortic aneurysms are a dilatation of the aorta, localized preferentially above the bifurcation of the iliac arteries, which increases in time. Understanding their localization and g ...
This paper presents an approach to simulating alternative Supply Chain configurations and analysing their respective sensitivities to external factors. First of all, the approach used for modelling the Supply Chain environment, characterized by uncertain f ...

We calculate learning rates when agents are informed through public and private observation of other agents' actions. We characterize the evolution of the distribution of posterior beliefs. If the private learning channel is present, convergence of the dis ...
