this paper compares clusters of aligned persian and english texts obtained from k-means method. text clustering has many applications in various fields of natural language processing. so far, much english documents clustering research has been accomplished. now this question arises, are the results of them extendable to other languages? since the goal of document clustering is grouping of docum...

A graph G is (j, k)-colorable if its vertices can be partitioned into subsets V1 and V2 such that in G[V1] every vertex has degree at most j and in G[V2] every vertex has degree at most k. We prove that if k ≥ 2j + 2, then every graph with maximum average degree at most 2 ( 2− k+2 (j+2)(k+1) ) is (j, k)colorable. On the other hand, we construct graphs with the maximum average degree arbitrarily...

BACKGROUND The Korean version of the Michigan Hand Outcomes Questionnaire (K-MHQ) was recently validated; however, the questionnaire's responsiveness as well as the degree to which the instrument is sensitive to change has not been thoroughly evaluated in a specific condition in Koreans. We evaluated the responsiveness of the K-MHQ in a homogenous cohort of patients with carpal tunnel syndrome ...

We give a simple proof of Jackson’s terminating q-analogue of Dixon’s identity. In the last twenty years several short proofs of Dixon’s identity have been published [3–5]. However, there are not so many proofs of Jackson’s terminating q-analogue of Dixon’s identity [2, 6]: ∑ k (−1)kq(3k2+k)/2 [ a+ b a+ k ][ a+ c c+ k ][ b+ c b+ k ] = [a+ b+ c]! [a]![b]![c]! , (1) where [n]! = ∏n i=1 1−qi 1−q a...

Recent research indicates that the pathophysiology of breast-cancer-related lymphoedema (BCRL) is more complex than simple axillary lymphatic obstruction as a result of the cancer treatment. Uneven distribution of swelling (involvement of the mid-arm region is common, but the hand is often spared) is puzzling. Our aim was to test the hypothesis that local differences in lymphatic drainage contr...

coordination, body and limb designs are related to the environmental objects and events. the aim of this study was to investigate the necessity to implement rope jumping program in iran schools and since one of the major problems in learning how to write is eye–hand coordination, the effect of a rope jumping training course on eye–hand coordination was investigated in the fourth grade elementar...

This article described analytic approaches in developing practical models for large-scale PCS networks, Based on the ow equivalent assumption (the rate of portables move into a cell equals to the rate of portables move out of the cell), a portable population model was described. The model provides the steady-state portable population distribution in a cell which is independent of the portable r...

     The purpose of this work was to develop once daily sustained release (SR) matrix tablets of naproxen, an anti-inflammatory agent. The tablets were prepared by wet granulation method along with hydrophilic matrix materials like Methocel K 15M CR and Methocel K 100M CR. The granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. The ...
