BNT162b2 antigen dose and SARS-CoV-2 omicron infection in adolescents
( Elsevier , 2023 , Other)COVID-19 vaccine antigen dose might affect protection against SARS-CoV-2 infection,1, 2 but direct evidence to quantify this effect is absent. We conducted a matched, retrospective, cohort study using a regression ... -
Body composition, blood pressure and dietary habits among young qatari male adults
(2013 , Poster)Introduction: Due to a rapidly changing lifestyle in Qatar, determinants of non-communicable diseases and linked levels of risk factors have risen. These facts pose a national challenge (1). Information about Qatari adults` ... -
Bone benefits of fish oil supplementation depend on its EPA and DHA content
( MDPI AG , 2019 , Article)The preventive effect of high-dose (9%) regular-fish oil (FO) against bone loss during aging has been demonstrated, but the effects of a low-dose (1%–4%) of a highly purified concentrated FO (CFO) has not been elucidated. ... -

Bootstrap confidence intervals for adaptive cluster sampling design based on Horvitz-Thompson type estimators
( Kluwer Academic Publishers , 2014 , Article)Perez and Pontius (J Stat Comput Simul 76:755-764, 2006) introduced several bootstrap methods under adaptive cluster sampling using a Horvitz-Thompson type estimator. Using a simulation study, they showed that their proposed ... -
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
( American Society for Microbiology , 2005 , Article)Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ... -
Born small, die young: Intrinsic, size-selective mortality in marine larval fish
( Nature Publishing Group , 2015 , Article)Mortality during the early stages is a major cause of the natural variations in the size and recruitment strength of marine fish populations. In this study, the relation between the size-at-hatch and early survival was ... -
Borrowed words in Qatari Arabic: A case study of knowledge of meaning and knowledge of origin by Qataris
( University of Akron , 2017 , Article)Linguistic borrowing is a common, universal and intensively studied phenomenon. It is of interest to investigate this practice and its patterns in Qatari Arabic and to know to what extent the Qataris know the meaning and ... -
Borrowed Words In Qatari Dialect: A Case Study
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)According to Graddol (2004) "The world's language system is undergoing rapid change because of demographic trends, new technology, and international communication. These changes will affect both written and spoken ... -
Boundary linear-quadratic control for a system of coupled parabolic-hyperbolic PDEs and ODE
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)The paper deals with the design of a boundary optimal controller for a general model of parabolic-hyperbolic PDEs coupled with an ODE. The augmented infinite-dimensional state space representation has been used in order ... -
Boundary optimal (LQ) control of coupled hyperbolic PDEs and ODEs
( Elsevier , 2013 , Article)This contribution addresses the development of a linear quadratic (LQ) regulator for a set of hyperbolic PDEs coupled with a set of ODEs through the boundary. The approach is based on an infinite-dimensional Hilbert ... -
Boundary optimal control design for a system of parabolic-hyperbolic PDEs coupled with an ODE
( Taylor and Francis Ltd. , 2020 , Article)This paper deals with the design of a boundary optimal controller for a general model of parabolic-hyperbolic PDEs coupled with an ODE. The augmented infinite-dimensional state-space representation has been used in order ... -
Boundary optimal control of coupled parabolic PDE-ODE systems
( IFAC Secretariat , 2014 , Conference Paper)This paper deals with boundary optimal control problem for coupled parabolic PDEODE systems. The problem is studied using infinite-dimensional state space representation of the coupled PDE-ODE system. Linearization of the ... -
Boundary Output-Feedback Regulation of a Catalytic Cracking Reactor
( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)This work focuses on the design of a boundary output feedback regulator for a catalytic cracking reactor model which can be represented by a set of partial differential equations (PDEs). Based on the linear abstract ... -
Boundedness of rough integral operators on triebel-lizorkin spaces
( Universitat Autonoma de Barcelona, Seccio de Matematiques , 2012 , Article)We prove the boundedness of several classes of rough integral operators on Triebel-Lizorkin spaces. Our results represent improvements as well as natural extensions of many previously known results. -
Braking effect of climate and topography on global change-induced upslope forest expansion
( Springer New York LLC , 2017 , Article)Forests are expected to expand into alpine areas due to global climate change. It has recently been shown that temperature alone cannot realistically explain this process and that upslope tree advance in a warmer scenario ... -
Breaking up prolonged sitting time with walking does not affect appetite or gut hormone concentrations but does induce an energy deficit and suppresses postprandial glycaemia in sedentary adults
( NRC Research Press , 2016 , Article)Background: Breaking up periods of prolonged sitting can negate harmful metabolic effects but the influence on appetite and gut hormones is not understood and is investigated in this study. Methods: Thirteen sedentary (7 ... -
Breaking up prolonged sitting with moderate-intensity walking improves attention and executive function in Qatari females
( Public Library of Science , 2019 , Article)Background Cultural, environmental and logistical factors promote a sedentary lifestyle within Qatar, particularly for females. Sedentary behaviour is acutely associated with poor cognitive function and fatigue, and ... -
