Data from the first run of the BABAR detector at the PEP II accelerator are presented. Measurements of many rare B decay modes are now possible using the large data sets currently being collected by BABAR. An overview of analysis techniques and results on data collected in 2000 are described.

BACKGROUND Cluster-randomized trials, in which health interventions are allocated randomly to intact clusters or communities rather than to individual subjects, are increasingly being used to evaluate disease control strategies both in industrialized and in developing countries. Sample size computations for such trials need to take into account between-cluster variation, but field epidemiologis...

The speed of digital circuit is one of the most restricting factors in the deep sub-micron and multigigahertz integrated circuits design. It is directly dependent on the circuit delay. Scaling down the technologies and increasing the operational frequency make the delay problems more important. This paper studies the delay in digital circuits, starting from the design process, scaling down the ...

purpose: in the present study we have tried to find the most reliable intraocular lens (iol) power calculation formula in patients with keratoconus (kcn) and cataract. methods: in a prospective case series between october 2010 and march 2012, eligible patients with cataract and kcn underwent phacoemulsification with iol implantation. preoperatively, based on iol master keratometric data iol pow...

Surveillance is critical to mounting an appropriate and effective response pandemics. However, aggregated case report data suffers from reporting delays can lead misleading inferences. Different data, line list a table contains individual features such as dates of symptom onset for each reported good source modeling delays. Current methods are not particularly which typically has missing that n...

we present a new renormalization-group calculation of the octagonal tiling excitation spectrum. Two new self-;imilar octagonal tilings are introduced, a triangle-Lite and a triangle-dan tiling, which are entangled with the standard rhombus-~quare tiling. The decimation procedure involved in the renormalization group calculation transforms each tiling enta a different one and goe; back tu the (r...
