Universal large-order asymptotic behavior of the strong-coupling and high-temperature series expansions
( American Physical Society , 2022 , Article)For theories that exhibit second-order phase transition, we conjecture that the large-order asymptotic behavior of the strong-coupling (high-temperature) series expansion takes the form σnnb where b is a universal ... -
An upper bound of the basis number of the semi-strong product of cycles with bipartite graphs
( The Korean Mathematical Society , 2007 , Article)An upper bound of the basis number of the semi-strong product of cycles with bipartite graphs is given. Also, an example is presented where the bound is achieved. -
Use of post-stratification in composite sampling for estimating mean
( Springer , 2011 , Article)We show with the results of a study conducted in the Hamadan Province, Iran as to how the use of composite sampling for estimating mean zinc concentration in the soil can help reduce analytical costs by reducing the number ... -
Using Grades in Core Curriculum Chain Courses as Predictors of Academic Performance in Subsequent Courses: A Study at Qatar University
( SAGE Publications Inc. , 2023 , Article)The study aimed to investigate students' final grades in a linked course or chain course to determine any effect on students' academic performance in their next linked course. Courses with high D, F, and W grades were ... -
Utilization of simulated patients to assess diabetes and asthma counseling practices among community pharmacists in Qatar
( Springer Netherlands , 2017 , Article)Background Patient counseling is one of the most important services a pharmacist can provide to patients. Studies have shown that counseling provided by pharmacists may prevent medication related problems and improve ... -
Vacuum structure and PT -symmetry breaking of the non-Hermetian (iϕ3) theory
( American Physical Society , 2017 , Article)In this work, we study the PT -symmetric (iϕ3) theory using the effective action formalism. To test the accuracy of the used technique, we apply it first to the PT -symmetric (−ϕ4) theory, where we reproduce the same results ... -
Validation and cultural adaptation of the Arabic versions of the Mini?Mental status examination - 2 and Mini-Cog test
( Dove Medical Press Ltd. , 2017 , Article)Introduction: The elderly population is increasing around the world, and the prevalence of dementia increases with age. Hence, it is expected that the number of people with dementia will increase significantly in the coming ... -
Validation of the Arabic version of the Social Communication Questionnaire
( SAGE Publications Ltd , 2019 , Article)Validated screening and diagnostic tools for autism spectrum disorder for use in Arabic-speaking individuals are scarce. This study validated the Arabic version of the Social Communication Questionnaire. The total study ... -
Validity of the effective potential method to study PT-symmetric field theories
( Elsevier B.V. , 2019 , Article)We calculate the one loop effective potential for the class (-(iϕ)α) of PT-symmetric and non-Hermitian field theories in 0+1 space-time dimensions. To test the method, we showed that for the massless Hermitian ϕ4 theory, ... -
Weak and strong convergence theorems for generalized nonexpansive mappings
( Universitatii Al.I.Cuza din Iasi , 2016 , Article)We consider a class of generalized nonexpansive mappings introduced by Karapinar and seen as a generalization of Suzuki (C)-condition. We prove some weak and strong convergence theorems for approximating fixed points of ... -
Weak and strong convergence theorems without some widely used conditions
( Academic Publications, Ltd. , 2010 , Article)We establish weak (strong) convergence of Ishikawa iterates of two asymptotically (quasi-)nonexpansive maps without any condition on the rate of convergence associated with the two maps. Moreover, our weak convergence ... -
Weighted estimates for oscillatory singular integrals
(2013 , Article)We establish uniform bounds for oscillatory singular integrals as well as oscillatory singular integral operators. We allow the singular kernel to be given by a function in the Hardy space H1(Sn-1), while such results were ... -
Weighted estimates for rough parametric Marcinkiewicz integrals
( Korean Mathematical Society , 2007 , Article)We establish a weighted norm inequality for a class of rough parametric Marcinkiewicz integral operators . As an application of this inequality, we obtain weighted inequalities for a class of parametric Marcinkiewicz ... -
Why is it so difficult to attract FDI to the MENA countries ?
( Science Publications , 2016 , Article)In this study we constructively argue that the relationship between FDI flows and the per capita GDP for the MENA countries has a novel feature-hitherto unrecognised-which can partially explain the great difficulty of the ... -
Wireless transmission using cooperation on demand
( Elsevier B.V. , 2009 , Article)Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the cooperation is triggered only if the ...
