Background and purpose: Q fever is a worldwide zoonosis which is an endemic in many regions. Its diagnosis is usually missed especially in human. This research aimed at investigating acute Q fever among suspected patients in northern Iran. Materials and methods: This cross-sectional study was conducted in 56 suspected cases of Q fever selected from 476 febrile patients admitted in Qaemshahr R...
In this paper, we apply a general family of basic (or q-) polynomials with double q-binomial coefficients as well some homogeneous q-operators in order to construct several q-difference equations involving seven variables. We derive the Rogers type and extended formulas Srivastava-Agarwal-type bilinear generating functions for q-polynomials, which generalize Cigler polynomials. also class mixed...
let $g$ be a finite group. we construct the prime graph of $ g $,which is denoted by $ gamma(g) $ as follows: the vertex set of thisgraph is the prime divisors of $ |g| $ and two distinct vertices $ p$ and $ q $ are joined by an edge if and only if $ g $ contains anelement of order $ pq $.in this paper, we determine finite groups $ g $ with $ gamma(g) =gamma(l_3(q)) $, $2 leq q < 100 $ and prov...
هدف این مطالعه بررسی تاثیر نسبت q توبین و نرخ رشد درآمد بر سطح سرمایه گذاری است. برای این منظور 100 شرکت از بورس اوراق بهادار تهران برای سالهای 87_1381 مورد مطالعه قرار گرفتند. شرکتها از نظر نسبت q توبین به دو گروه شرکتهایی با نسبت q توبین کوچکتر از 1 و شرکتهایی با نسبت q توبین بزرگتر از 1 تقسیم شدند. نتایج رگرسیون نشان داد که برای تمامی شرکتها نسبت q توبین بر سطح سرمایه گذاری تاثیر معنادار و م...
برای عدد اول $q$ و عدد صحیح $jleq q$، کد $c(q,j)$ دسته ای از کدهای آرایه ای با ماتریس بررسی توازن خلوت است که ساختار جبری مناسبی دارند. در این پایان نامه کمترین فاصله $d(q,j)$ از این کدها را بررسی می کنیم. ابتدا ثابت می کنیم که کد تحت گروه دوبار متعدی از جایگشت های آفین پایا است سپس برای هر عدد اول $q>7$ نشان می دهیم $d(5,4)=8$، $...
in this paper we show that if q is a power of a prime p , then the projective special linear group psl(2, q) and the stabilizer of a point of the projective line have maximum sum element orders among all proper subgroups of projective general linear group pgl(2, q) for q odd and even respectively
This paper presents the concepts of $(L,M)$-fuzzy Q-convergence spaces and stratified $(L,M)$-fuzzy Q-convergence spaces. It is shown that the category of stratified $(L,M)$-fuzzy Q-convergence spaces is a bireflective subcategory of the category of $(L,M)$-fuzzy Q-convergence spaces, and the former is a Cartesian-closed topological category. Also, it is proved that the category of stratified $...
In this paper we derive convergence rates for Q-learning. We show an interesting relationship between the convergence rate and the learning rate used in Q-learning. For a polynomial learning rate, one which is 1/t at time t where ω ∈ (1/2, 1), we show that the convergence rate is polynomial in 1/(1− γ), where γ is the discount factor. In contrast we show that for a linear learning rate, one whi...
Abstract. Many discrete integrable systems exhibit the Laurent phenomenon. In this paper, we investigate three integrable systems: the Somos-4 recurrence, the Somos-5 recurrence and a system related to so-called A1 Q-system, whose general solutions are derived in terms of Hankel determinant. As a result, we directly confirm that they satisfy the Laurent property. Additionally, it is shown that ...
