It results in real costs to organisations and possibly an increasing reluctance to use email by some users. Currently most spam prevention techniques rely on methods that examine the whole email message at the mail server. This paper describes research(More)
The prevalence of immunologic and coagulation disorders in 75 schizophrenic patients treated with chlorpromazine or other antipsychotic drugs was evaluated. Four groups were studied: Group A, chlorpromazine treatment for more than 2 1/2 years; Group B, chlorpromazine and other antipsychotic drug treatment for more than 2 1/2 years; Group C, chlorpromazine(More)
The purpose of this study was to determine the dynamic characteristics of brachial artery dilation in response to step increases in shear stress [flow-mediated dilation (FMD)]. Brachial artery diameter (BAD) and mean blood velocity (MBV) (Doppler ultrasound) were obtained in 15 healthy subjects. Step increases in MBV at two shear stimulus magnitudes were(More)
A taxonomy of system attacker behavior reveals security vulnerabilities in RFID authorization and monitoring systems. RFID systems are classified by their informational goals-typically, authorization and monitoring. Authorization systems replace the more traditional approaches of granting an entity access to a particular zone, whereas monitoring systems(More)
Alterations of left ventricular mass occur in a variety of congenital and acquired heart diseases. In vivo determination of left ventricular mass, using several different techniques, has been previously reported. Problems inherent in some previous methods include the use of ionizing radiation, complicated geometric assumptions and invasive techniques. We(More)
Previous studies have shown that hypertension and left ventricular hypertrophy (HT-LVH) increase completed infarct size. Myocardial infarction progresses in a wavefront of myocardial necrosis from the subendocardium to the subepicardium. We tested two hypotheses: First, HT-LVH accelerates the wavefront of myocardial necrosis when compared with normotensive(More)
