in this paper, the use of weighted pairwise likelihood instead of the full likelihood in estimating the parameters of the multivariate ar(1) is investigated. a closed formula for typical elements of the godambe information(sandwich information) is presented. some efficiency calculations are also given to discuss the feasibility andcomputational advantages of the weighted pairwise likelihood app...
spleen is the most frequent solid organ to be injured in blunt abdominal trauma. considering its important role in providing immunity and preventing infection by a variety of mechanisms, every attempt should be made, if possible, to salvage the traumatized spleen at any age particularly in children. after primary resuscitation, mandatory requirements for non-operative management include absence...
in our paper [a. b. m. basheer and j. moori, on a group of the form $2^{10}{:}(u_{5}(2){:}2)$] we calculated the inertia factors, fischer matrices and the ordinary character table of the split extension $ 2^{10}{:}(u_{5}(2){:}2)$ by means of clifford-fischer theory. the second inertia factor group of $2^{10}{:}(u_{5}(2){:}2)$ is a group of the form $2_{-}^{1+6}{:}((3^{1+2}{...
شواهد آزمایشگاهی قوی و آنالیز مقیاس بندی نشان داده است که رشد تومورها متعلق به کلاسجهانی 1 هستند. این نوع رشد توسط سه ویژگی توصیف میشود: 1( نرخ رشد خطی 2( محدودیت mbeتکثیر سلول در حاشیهی تومور )3( انتشار سطحی سلولها در لبهی در حال رشد. تمامی این حالات1+ بصورت تجربی نیز مشاهده شده است. معادلات دیفرانسیلی جزئی تصادفی برای تومورهای ) 1بعدی، با تقارنهای صحیح هندسهی تومور معرفی شدهاند که بعنوان یک ر...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
the adhesion molecules are involved in adhesion of leukocytes to endothelial cells and other immune cells. not only adhesion molecules have membrane form, but they also have soluble form. in this paper, we attempted to investigate the concen¬tration of soluble adhesion molecules in the type 1 diabetic patients (n = 40) and healthy subjects (n = 10). the results indicated that there was an incre...
