In this paper, we introduce a goodness of fit test for expo- nentiality based on Lin-Wong divergence measure. In order to estimate the divergence, we use a method similar to Vasicek’s method for estimat- ing the Shannon entropy. The critical values and the powers of the test are computed by Monte Carlo simulation. It is shown that the proposed test are competitive with other tests of exponentia...

compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (npr) have been numerically studied with severalturbulence models. the numerical results reveal that, the sst k–ω model give the bestresults compared with other models in time and accuracy. the effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...

the russian foreign policy toward various issues is often combined with complexity, ambiguity and conflicts. this fact was true at least in the history of relations between iran and russia, so that russian face is depicted as an unreliable partner for the iranian citizens and elites. with the importance of this issue, the study aims to answer this central question: what are the reasons for thes...

This research aims to investigate the effect of conservative reporting on the investors' opinion divergence at the time of earnings announcement in a 5 year period during 2012-2016; the required data have been collected from Tehran Securities and Stock Exchange Organization and the population is consisted of 585 corporates-years which have been selected by the systematic removal sampling. To in...

Animals capable of moving in different environments might face conflicting selection on morphology, thus posing trade-offs the relationships between morphology and locomotor performance each these environments. Moreover, given distinct ecological roles sexes, can be sexually dimorphic. In this article, I studied morphological traits male female semiaquatic Pleurodeles waltl newts their aquatic ...

Nonnative cichlids (Coptodon zillii) have established populations in the Köyceğiz and Koca Lakes, located on west coasts of Mediterranean Turkey. Conflicting species names these lakes been reported for many years. We studied samples from current Coptodon Pecenek canal concerning existing GenBank data. estimated possible ancestral population using sequence data mitochondrial D-loop segment. Inte...

Evolutionary conflicts cause opponents to push increasingly hard and in opposite directions on the regulation of traits. One can see only the intermediate outcome from the balance of the exaggerated and opposed forces. Intermediate expression hides the underlying conflict, potentially misleading one to conclude that trait regulation is designed to achieve efficient and robust expression, rather...

Abstract Recently self-supervised learning is gaining popularity for Graph Neural Networks (GNN) by leveraging unlabeled data. Augmentation plays a key role in self-supervision. While there common set of image augmentation methods that preserve labels general, graph do not guarantee consistent semantics and are usually domain dependent. Existing GNN models often handpick small techniques limit ...
