The disorder function formalism (Gunaratne et al 1998 Phys. Rev. E 57 5146) is used to show that pattern relaxation in an experiment on a vibrating layer of brass beads occurs in three distinct stages. During stage I, all length scales associated with moments of the disorder grow at a single universal rate, given by L(t) ∼ t0.5. In stage II, pattern evolution is non-universal and includes a ran...

background: the clinical diagnosis of meningitis is crucial, particularly in children. the early diagnosis and empiric an­tibi­otic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16srdna frag­ment which is produced by universal primers led up fast and sensitive determination. the purpose of this study was to investi­gate a rapid method fo...

This study explores the awareness, knowledge, attitude and practice of Universal Precautions (UPs) among radiographers as well as their sensitivity towards the possibility of being occupationally exposed and extent of their exposure to infections. A total of 24 radiographers were assessed. The index used to assess the awareness was how they knew about universal blood and body fluid precautions....

-Lossless block-to-variable length source coding is studied for finite-state, finite-alphabet sources. We aim to minimize the probability that the normalized length of the codeword will exceed a given threshold B, subject to the Kraft inequality. It is shown that the Lempel-Ziv (LZ) algorithm asymptotically attains the optimal performance in the sense just defined, independently of the source a...

OBJECTIVES Biventricular pacing acutely improves left ventricular function in patients with heart failure and left ventricular dyssynchrony. Pressure-volume loop analysis has shown acute perioperative hemodynamic benefits of biventricular pacing immediately after weaning from cardiopulmonary bypass in patients undergoing coronary artery bypass grafting, but whether these effects can be maintain...
