Native language identification (NLI) is the task of determining the native language of an author writing in a second language. Several pieces of earlier work have found that features such as function words, part-of-speech n-grams and syntactic structure are helpful in NLI, perhaps representing characteristic errors of different native language speakers. This paper looks at the idea of using Lat...

A criterion for systematization of organic compounds is described. Organic (estimated to 16-20 millions) are three types: (A) symmetric (especially meso and C2 symmetric), (B) possible symmetry generators, i.e. possessing a real or imaginary, but plausible, correspondent: irrechi (from irregular distribution chiral carbons) constitutional), (C) archaic (or primitive) that neither nor generators...

We discuss coherent QCD radiation from space-like parton branching and its effects on multi-jet final states at high-energy hadron colliders. Coherence effects for small longitudinal momentum fractions x are not included in the branching algorithms of standard shower Monte Carlo event generators. On the other hand, they are taken into account only partially in perturbative next-to-leading-order...

The proposed last research entitled "An Effective Data Comparison of Graph Clustering Algorithms via Random Graphs" compared two mostly used algorithms for graph clustering i. e. restricted neighborhood search and markov clustering algorithms via random graph generators i. e. Erdos-Renyi and power law graphs. This paper is an extension to our last research work. In this we have examin...

In this paper a piecewise-dependent-data (PDD) clustering algorithm is presented, and a proof of its convergence to a local minimum is given. A distortion measure-based model represents each cluster. The proposed algorithm is iterative. At the end of each iteration, a competition between the models is performed. Then the data is regrouped between the models. The “movement” of the data between t...

A group is coherent if all its finitely generated subgroups are finitely presented. In this article we provide a criterion for positively determining the coherence of a group. This criterion is based upon the notion of the perimeter of a map between two finite 2-complexes which is introduced here. In the groups to which this theory applies, a presentation for a finitely generated subgroup can b...

We call a graded connected algebra R effectively coherent, if for every linear equation over R with homogeneous coefficients of degrees at most d, the degrees of generators of its module of solutions are bounded by some function D(d). For commutative polynomial rings, this property has been established by Hermann in 1926. We establish the same property for several classes of noncommutative alge...

This paper presents the results of a large scale empirical study of coherent dependence clusters. All statements in a coherent dependence cluster depend upon the same set of statements and affect the same set of statements; a coherent cluster’s statements have ‘coherent’ shared backward and forward dependence. We introduce an approximation to efficiently locate coherent clusters and show that i...

Entropy considerations are used to determine the types of subtle interactions (SI), or psi phenomena, that are consistent with the second law of thermodynamics. The analysis is preceded by a short tutorial on entropy and the second law of thermodynamics. For a coherent advanced (retrocausation) signal to exist, it would conflict with the second law in forward time because it would require a red...

In this paper two types of coherent states of gl q (2)-covariant oscil-lators are investigated. 1 Quantum groups or q-deformed Lie algebra implies some specific deformations of classical Lie algebras. From a mathematical point of view, it is a non-commutative associative Hopf algebra. The structure and representation theory of quantum groups have been developed extensively by Jimbo [1] and Drin...
