Nonstandard lepton-quark contact interactions may arise at low energies as a consequence of a common quark and lepton substructure or of heavy boson exchanges, when integrated out. There has recently been renewed interest @1# in contact interactions due to the fact that they are one of the potential explanations of the excess of events reported by H1 @2# and ZEUS @3#, the DESY ep collider at HE...

|Evolutionary design of artiicial neural networks (ANNs) ooers a very promising and automatic alternative to designing ANNs manually. The advantage of evolutionary design over the manual design is their adaptability to a dynamic environment. Most research in evolving ANNs only deals with the topological structure of ANNs and little has been done on the evolution of both topological structures a...

Enabling preserving bisimilarity is a refinement of strong that preserves safety as well liveness properties. To define it properly, labelled transition systems needed to be upgraded with successor relation, capturing concurrency between transitions enabled in the same state. We enrich well-known De Simone format handle inductive definitions this relation. then establish ep-bisimilarity congrue...

Objective(s): In this study, we desvcribe a simple eco-friendly approach for the synthesis of a potent, stable and benign silver nanoparticles to carry and deliver chalcones and dihydrochalcones present in a methanol extract of Eysenhardtia polystachya (EP). Materials and Methods: In this process silver nanoparticles carring EP compounds (EP/AgNPs) are synthesized in a single step by eliminatin...

in this paper, we determine the structure of the space of multipliers of the range of a composition operator cφ that induces by the conditional expectation between two lp() spaces.

X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starti...

In this article we consider the approximate description of doubly–dispersive channels by its symbol. We focus on channel operators with compactly supported spreading, which are widely used to represent fast fading multipath communication channels. The concept of approximate eigenstructure is introduced, which measures the accuracy Ep of the approximation of the channel operation as a pure multi...
