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 ... -
Bootstrap-Based Quality Metric for Scarce Sensing Systems
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)This paper considers Mobile Crowd-Sensing (MCS) systems that suffer from scarce participant availability due to small sample sizes in each sensing cycle. With such small sample sizes, a sample in error would dramatically ... -
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 ... -
Boron removal from saline water by a microbial desalination cell integrated with donnan dialysis
( Elsevier , 2015 , Article)Boron has toxic effects on plant growth and thus its removal is necessary from desalinated saline water for irrigation application. Microbial desalination cells (MDCs) are a new approach for effective desalination but boron ... -
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 ... -

Both Short and Long Sleep Durations Are Associated with Poor Cognition and Memory in Chinese Adults Aged 55+ Years-Results from China Health and Nutrition Survey.
( MDPI , 2022 , Article)We aimed to examine the associations between sleep duration and cognitive functions and memory in older Chinese adults attending the China Health and Nutrition Survey. A total of 7924 participants 55 years and older who ... -
Bottom-up rather than top-down: evidence from Middle Eastern and North African educational institutions
( Emerald , 2020 , Article)Purpose: Educational institutions in the Middle East and North Africa (MENA) are striving for better resource management and finance. The bottom-up budgeting approach plays an important role in motivating executives' ... -
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.
