One way of smoothing out the sign problem is to do part of the integral analytically, and the remainder using MC. The analytical summation is not just directly over a subset of the dynamical variables; in general it can be a renormalisation group (RG) blocking where coarse-grained variables are introduced. This does yield certain improvement over the crude MC in general. Let P{V , V } be the no...

A new method for the synthesis of 1H-indazoles from readily available N-tosylhydrazones and nitroaromatic compounds has been developed. This transformation occurs under transition-metal-free conditions and shows a wide substrate scope. The method has been successfully applied to the formal synthesis of a bioactive compound, WAY-169916.

Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive beh...

This study was an attempt to investigate the effect of metacognitive strategies (MS) on speakingability of the learners and also what MS are specifically employed by learners when it comes todifferent task types. To this end, running a quasi-experimental study, 60 students at advancedlevel (female) from Shenia Language Institute in Sanandaj were randomly selected and given anOxford Placement Te...

A quasi-kernel of a digraph D is an independent set Q⊆V(D) such that for every vertex v∈V(D)﹨Q, there exists directed path with one or two arcs from v to u∈Q. In 1974, Chvátal and Lovász proved has quasi-kernel. 1976, Erdős Székely conjectured sink-free D=(V(D),A(D)) size at most |V(D)|/2. this paper, we give new method show the conjecture holds generalization anti-claw-free digraphs. For any o...

Verification and validation (V&V) techniques have always been an essential part of the knowledge engineering process, because they offer the only way to judge the success (or otherwise) of a knowledge base development project. This remains true in the context of knowledge management: V&V techniques provide ways to measure the quality of knowledge in a knowledge base, and to indicate where work ...

The definition of a category of (T,V)-algebras, where V is a unital commutative quantale and T is a Set-monad, requires the existence of a certain lax extension of T. In this article, we present a general construction of such an extension. This leads to the formation of two categories of (T,V)-algebras: the category Alg(T,V) of canonical (T,V)-algebras, and the category Alg(T′,V) of op-canonica...

An extended triple system with no idempotent element (ETS) is a collection of non ordered triples of type {x,y,z} or {x,x,y} chosen from a v set in such a way that each pair (whether distinct or not) is contained in exactly one triple. (For example, in the block {x,x,y}, the pair {x,y} is said to occur one tinle.) Such a design has "'v = v(v + 3) /6 blocks and a necessary and sufficient conditi...
