OBJECTIVE To determine whether the relationships of lifetime discrimination to ambulatory blood pressure (ABP) varied as a function of age in a sample of Black and Latino(a) adults ages 19 - 65. METHOD Participants were 607 Black (n = 318) and Latino(a) (n = 289) adults (49% female) who completed the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV), which assesses lif...

OBJECTIVE To describe the prevalence of posttraumatic stress disorder (PTSD) and comorbid psychiatric disorders and identify correlates of PTSD in a contemporary, nationally representative sample of US veterans. METHOD Data were analyzed from Wave 1 of the National Health and Resilience in Veterans Study, a cross-sectional, retrospective, web-based survey of a population-based sample of 3,157...

We consider the maximum lifetime routing problem in wireless sensor networks in two settings: (a) when nodes’ initial energy is given, and (b) when it is subject to optimization. The optimal solution and objective value provide optimal flows and the corresponding predicted lifetime, respectively. We stipulate that there is uncertainty in various network parameters (available energy and energy d...

objective:  to evaluate the frequency of different psychiatric disorders among 7 to 12 years old children in urban areas of tehran. method: a sample of 799 children (6 to 11 years old) were selected from 250 clusters of the entire 22 municipality areas of tehran using a multistage sampling method from 250 clusters from the entire 22 municipality areas of tehran.. after responding to a persian v...

We consider a mobile ad hoc network consisting of three types of nodes (source, destination and relay nodes) and using the two-hop relay routing. This type of routing takes advantage of the mobility and the storage capacity of the nodes, called the relay nodes, in order to route packets between a source and a destination. Packets at relay nodes are assumed to have a limited lifetime in the netw...

business all around the world uses different approaches to know their customers, segment them and formulate suitable strategies for them. one of these approaches is calculating the value of each customer for the company. in this paper by calculating customer lifetime value (clv) for individual customers of an online toy store named alakdolak, three customer segments are extracted. the level of ...

following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...

CONTEXT Little is known about lifetime prevalence or age of onset of DSM-IV disorders. OBJECTIVE To estimate lifetime prevalence and age-of-onset distributions of DSM-IV disorders in the recently completed National Comorbidity Survey Replication. DESIGN AND SETTING Nationally representative face-to-face household survey conducted between February 2001 and April 2003 using the fully structur...

For brittle failures, the probability distribution of structural strength and lifetime are known to be Weibullian, in which case the knowledge of the mean and standard deviation suffices to determine the loading or time corresponding to a tolerable failure probability such as 10−6. Unfortunately, this is not so for quasibrittle structures, characterized by material inhomogeneities that are not ...

Submitted for the DFD12 Meeting of The American Physical Society Lifetime Characterization of Electro-Luminescence Based Pressure-Sensitive Paint System for Unsteady Flow Field Measurements YOSHIMI IIJIMA, HIROTAKA SAKAUE, JAXA — Electro-luminescence based pressure-sensitive paint (EL-PSP) system uses an EL as an illumination source for a PSP measurement. EL can be directly applied onto a PSP m...
