Microstructure reconstruction using entropic descriptors
A multi-scale approach to the inverse reconstruction of a pattern’s microstructure is reported. Instead of a correlation function, a pair of entropic descriptors (EDs) is proposed for stochastic optimization method. The first of them measures a spatial inhomogeneity, for a binary pattern, or compositional one, for a greyscale image. The second one quantifies a spatial or compositional statistic...
متن کاملEntropic security in quantum cryptography
We present two new definitions of security for quantum ciphers which are inspired by the definition of entropic security and entropic indistinguishability defined by Dodis and Smith. We prove the equivalence of these two new definitions. We also propose a generalization of a cipher described by Dodis and Smith and show that it can actually encrypt n qubits using less than n bits of key under re...
متن کاملQuantum entropic security
We present full generalizations of entropic security and entropic indistinguishability, notions introduced by Russell and Wang and then Dodis and Smith, to the quantum world where no assumption other than a limit on the knowledge of the adversary is made. This limit is quantified using the quantum conditional min-entropy as introduced by Renner. In this fully generalized model, we allow any kin...
متن کاملEntropic recoil separation of long DNA molecules.
A novel technique that can rapidly separate long-strand polymers according to length is presented. The separation mechanism is mediated by a confinement-induced entropic force at the abrupt interface between regions of vastly different configuration entropy. To demonstrate this technique, DNA molecules were partially inserted into a dense array of nanopillars (an entropically unfavorable region...
متن کاملModeling of the Chemico-Physical Process of Protonation of Molecules Entailing Some Quantum Chemical Descriptors
Relying upon the basic tenets of scientific modeling, an ansatz for the evaluation of proton affinity of molecules are evolved in terms of a four component model. The components of the model chosen are global descriptors like ionization energies, global softness, electronegativity and electrophilicity index. These akin quantum mechanical descriptors of atoms and molecules are linked with the ch...
