BACKGROUND The aims of this study were to measure the N-terminal fragment of pro-brain natriuretic peptide (proBNP) in plasma in medical conditions commonly found in primary care and to evaluate the utility of these measurements in identifying impaired cardiac function in elderly patients with symptoms associated with heart failure. METHODS We studied 415 patients (221 men and 194 women; mean...

This paper studies the location management problem in cellular wireless networks. We propose a HandoffVelocity Prediction (HVP) scheme to minimize the paging cost in searching a mobile terminal. HVP is based on the assumptions that the movement behavior of mobile terminals has temporal and spatial properties. Based on handoff statistics, the system maintains a handoff graph to describe the move...

The NASA passive Final Approach Spacing Tool (FAST) provides advisory information to the terminal air traffic controller for sequencing and merging of landing aircraft. It consists of the Trajectory Synthesizer (TS) and the Scheduling Logic (SL). FAST has undergone extensive field testing and performance evaluations of the FAST TS algorithms have been conducted. However, no analytical performan...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

  Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...

The problem of attitude consensus control is addressed for multiple rigid spacecraft under a fixed interaction network where only subset followers can obtain the leader's state information. To estimate and angular velocity leader, group distributed finite-time observers constructed each follower. Then fast non-singular terminal sliding mode controllers are proposed based on observed Rigorous pr...

in this paper the problem on “magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by n ahmad et.al.[7]” has been recapitulated using jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. it is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (refer equation(2.2)). this paper re...

Particle settling velocity is a fundamental parameter in sedimentology and engineering, has accordingly received much attention the literature. Grain properties, such as shape drag coefficient, which affect terminal velocity, also control threshold of initiation motion sediment entrainment into suspension. Terminal therefore provides insights dynamics modern past depositional environments impor...

most of iranian oil terminals are located in tropical regions and consequently, disorders of heat stress among workers are expected. there are many heat stress indices with self-advantages and disadvantages which are used for evaluating the amount of heat stress. the aim of the present study was to evaluate the reliability of wbgt, et and cet indices by comparison to core body temperature in kh...
