It is pointed out that quantum states, in general, contain a new kind of orders that cannot be characterized by symmetry. A concept of quantum order is introduced to describe such orders. As two concrete examples, we discussed quantum orders in free fermion systems and in 2D spin1/2 systems. We generalize the Landau’s theory for the classical orders and introduce projective symmetry group and F...
OBJECTIVES To assess the extent to which funding and study design are associated with high reprint orders. DESIGN Case-control study. SETTING Top articles by size of reprint orders in seven journals, 2002-09. PARTICIPANTS Lancet, Lancet Neurology, Lancet Oncology (Lancet Group), BMJ, Gut, Heart, and Journal of Neurology, Neurosurgery & Psychiatry (BMJ Group) matched to contemporaneous art...
let $g$ be a finite group and $pi_{e}(g)$ be the set of element orders of $g$. let $k in pi_{e}(g)$ and $m_{k}$ be the number of elements of order $k$ in $g$. set nse($g$):=${ m_{k} | k in pi_{e}(g)}$. in this paper, we prove that if $g$ is a group such that nse($g$)=nse($psl(2, 25)$), then $g cong psl(2, 25) $.

in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
Let p be prime. Let R be a discrete valuation ring of characteristic p with field of fractions K. Let C p denote the elementary abelian group of order p. In this paper we use Greither’s approach for classifying short exact sequences of finite R-group schemes to classify R-Hopf orders H in the group ring KC p , reproducing a result of Tossici. We then go further by providing an explicit descript...
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
Abstract Let G be a finite group and let ? ( ) denote the sum of element orders . It is well-known that maximum value on set groups order n , where positive integer, will occur at cyclic C For nilpotent groups, we prove natural generalization this result, obtained by replacing with relative to certain subgroup H
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
