We review the way the BTZ black hole relaxes back to thermal equilibrium after a small perturbation and how it is seen in the boundary (finite volume) CFT. The unitarity requires the relaxation to be quasi-periodic. It is preserved in the CFT but is not obvious in the case of the semiclassical black hole the relaxation of which is driven by complex quasi-normal modes. We discuss two ways of mod...
Merge-and-shrink abstraction (M&S) is an approach for constructing admissible heuristic functions for cost-optimal planning. It enables the targeted design of abstractions, by allowing to choose individual pairs of (abstract) states to aggregate into one. A key question is how to actually make these choices, so as to obtain an informed heuristic at reasonable computational cost. Recent work has...
RELAX NG is a new schema language for XML. This paper discusses various aspects of the design of RELAX NG including the treatment of attributes, datatyping, mixed content, unordered content namespaces, cross-references and modularity.
<p>Although fixed point theorems in modular spaces have remarkably applied to a wide variety of mathematical problems, these strongly depend on some assumptions which often do not hold practice or can lead their reformulations as particular problems normed vector spaces. A recent trend research has been dedicated studying the fundamentals and relaxing with ambition pushing boundaries theo...
We present in this paper a framework of approximate probabilistic inference which is based on three simple concepts. First, our notion of an approximation is based on “relaxing” equality constraints, for the purposes of simplifying a problem so that it can be solved more readily. Second, is the concept of “compensation,” which calls for imposing weaker notions of equality to compensate for the ...
AIMS The randomized clinical trial RELAX-AHF demonstrated a positive effect of vasodilator therapy with serelaxin in the treatment of AHF patients. The aim of our study was to compare clinical characteristics and outcomes of patients from the AHEAD registry who met criteria of the RELAX-AHF trial (relax-comparable group) with the same characteristics and outcomes of patients from the AHEAD regi...
Causal and Noncausal discrete{time transfer functions for some discrete{time system with zero order hold (ZOH), rst order hold (FOH) or ideal sampler are distinguished and described. In the case of ZOH or FOH the discussed notions are essential for the system with a continuous time plant described by the rational proper transfer function with the order of numerator equal to that of the denomina...
Traditional jitter-noise analysis which mainly focuses on the clock jitter errors for impulse-sampled signals cannot accurately model the sampled-data systems that practically include nonuniform sample-and-hold effects. This paper presents a comprehensive and robust analysis of the imperfections of nonuniformly sampled-and-held signals due to clock jitter. Both the general signal to overall jit...
