In this work, entropy scaling approaches for viscosity of pure Lennard-Jones (LJ) fluids and their mixtures have been investigated. To do so, we have used a reliable viscosity database available in the literature for the pure LJ fluids, and performed molecular dynamics simulations to generate a viscosity database over a wide range of thermodynamic conditions for LJ mixture fluids.

Compound selectivity is an important issue when developing a new drug. In many instances, a lack of selectivity can translate to increased toxicity. Protein kinases are particularly concerned with this issue because they share high sequence and structural similarity. However, selectivity may be assessed early on using data generated from protein kinase profiling panels.

The nonlinear coupler, which consists of two nonlinear oscillators linearly coupled together and one or two of these oscillators excited by external coherent fields, is investigated. We show that evolution of the nonlinear coupler is possible closed in a finite set of n-photon Fock states and can create Bell-like states.

This work considers the generation of ordinary differential equations whose solutions are the probability functions of wrapped exponential distribution. This will help in understanding the nature of exponential distribution when wrapped in a circle.

Ecological niche modelling or Predictive habitat distribution modelling framework for Sesamum mulayanum Nair, an important wild relative of oilseed crop Sesame has been analyzed using Maximum Entropy method. Based on the Ecological Niche model generated using the presence points only from Maharashtra state, potential states identified for the distribution wild sesame species (S. mulayanum) in India are Andhra Pradesh, Chhattisgarh, Karnataka, Kerala, Goa, Gujarat, Madhya Pradesh and Maharashtra.

This paper summarizes the symmetric image encryption results of 27 different algorithms, which include substitution-only, permutation-only or both phases. The cores of these algorithms are based on several discrete chaotic maps (Arnold’s cat map and a combination of three generalized maps), one continuous chaotic system (Lorenz) and two non-chaotic generators (fractals and chess-based algorithms).

Solving a set of coupled stochastic integro-differential equations involved in the problem with all initial conditions, we achieve analytical formulae for the complex probability amplitudes of n-photon states. In particular, evolution of the system generates maximally entangled states as so-called Bell-like states.

This system can be generated maximally entangled states. Specially, we can show that the entropy of entanglement and the maximally entangled states change dramatically when the initial conditions are different. The reasonableness obtained results is affirmed by the comparison to that of previous works.

Maxwell Boltzmann distribution with maximum entropy approach has been used to study the variation of political temperature and heat in a locality. We have observed that the political temperature rises without generating any political heat when political parties increase their attractiveness by intense publicity, but voters do not shift their loyalties.

This paper describes algorithms which rerank the top N hypotheses from a maximum-entropy tagger, the application being the recovery of named-entity boundaries in a corpus of web data. The first approach uses a boosting algorithm for ranking problems. The second approach uses the voted perceptron algorithm. Both algorithms give comparable, significant improvements over the maximum-entropy baseline. The voted perceptron algorithm can be considerably more efficient to train, at some cost in computation on test examples.

We present a constancy rate principle governing language generation. We show that this principle implies that local measures of entropy (ignoring context) should increase with the sentence number. We demonstrate that this is indeed the case by measuring entropy in three different ways. We also show that this effect has both lexical (which words are used) and non-lexical (how the words are used) causes.

In this paper we examine how the differences in modelling between different data driven systems performing the same NLP task can be exploited to yield a higher accuracy than the best individual system. We do this by means of an experiment involving the task of morpho-syntactic wordclass tagging. Four well-known tagger generators (Hidden Markov Model, Memory-Based, Transformation Rules and Maximum Entropy) are trained on the same corpus data. After comparison, their outputs are combined using several voting strategies and second stage classifiers. ...

This paper introduces a Maximum Entropy dependency parser based on an efficient kbest Maximum Spanning Tree (MST) algorithm. Although recent work suggests that the edge-factored constraints of the MST algorithm significantly inhibit parsing accuracy, we show that generating the 50-best parses according to an edge-factored model has an oracle performance well above the 1-best performance of the best dependency parsers. This motivates our parsing approach, which is based on reranking the kbest parses generated by an edge-factored model. ...

In this work, we present a novel approach to the generation task of ordering prenominal modifiers. We take a maximum entropy reranking approach to the problem which admits arbitrary features on a permutation of modifiers, exploiting hundreds of thousands of features in total. We compare our error rates to the state-of-the-art and to a strong Google ngram count baseline. We attain a maximum error reduction of 69.8% and average error reduction across all test sets of 59.1% compared to the state-of-the-art and a maximum error reduction of 68.
