ررسی مینیماکس بودن و هم متناهی بودن مدول های کوهمولوژی موضعی موضوع اصلی این رساله می باشد. در این راستا به بیان و اثبات چند قضیه می پردازیم. بدین منظور فرض کنید $r$ یک حلقه ی جابجایی و نوتری و $i$ ایده آلی از $r$ باشد. فرض کنید $m$ یک $-r$مدول ناصفر باشد. نشان می دهیم که $-n$ امین بعد متناهی برای هر $n in mathbb{n}_{circ}$ به صورت زیر می باشد: $$ f_{i}^{n}(m) := inf leftlb...
Incremental truncation is a method for constructing libraries of every one base pair truncation of a segment of DNA. Incremental truncation libraries can be created using a time-dependent nuclease method or through the incorporation of alpha-phosphothioate dNTPs by PCR or by primer extension (THIO(pcr) truncation and THIO(extension) truncation, respectively). Libraries created by the fusion of ...
We address the important question of the extent to which random variables and vectors with truncated power tails retain the characteristic features of random variables and vectors with power tails. We define two truncation regimes, soft truncation regime and hard truncation regime, and show that, in the soft truncation regime, truncated power tails behave, in important respects, as if no trunca...
We derive the asymptotic distributions of a semiparametric Dikta-type estimator and an inverse probability weighted type estimator of a survival function for a missing censoring indicator left truncated model and provide a theoretical comparison study.
In the natural history of Human Immunodeficiency Virus Type-1 (HIV-1) infection, many studies included the participants who were seropositive at time of enrollment. Estimation of the unknown times since exposure to HIV-1 in the prevalent cohorts is of primary importance for estimation of the incubation period of Acquired Immunodeficiency Syndrome (AIDS). To estimate incubation period of AIDS we...
In this paper, I investigate the formation and phonological alternations of Korean monosyllabic hypocoristics that are used without a vocative marker. result truncation merging. The study showed inclination to keep second syllable is more pronounced in truncated forms. most common type merging ‘onset 1st + rhyme 2nd syllable’. This illustrates symmetrical base anchoring template, which template...
