Bracketology, the art of successfully picking all the winners in the National Collegiate Athletic Association’s (NCAA) annual men’s Division I college basketball championship tournament, has become a favorite national activity. In spite of the challenges and uncertainty faced in this endeavor, patterns exist in how the seeds appear in each round, particularly the later rounds. This paper statis...

The dermal side of the chick embryonic skin was observed by scanning electron microscopy (SEM) after the removal of dermal components. Epidermis free of dermis was prepared as follows: Tissues were fixed, hydrolyzed with hydrochloric acid (HC1), digested with collagenase or trypsin, and processed for SEM observation. The epidermis from the anterior tarsometatarsus and the foot pad was examined....

In this work, we examine a generic class of simple distributed balls-into-bins algorithms. Exploiting the strong concentration bounds that apply to balls-into-bins games, we provide an iterative method to compute accurate estimates of the remaining balls and the load distribution after each round. Each algorithm is classified by (i) the load that bins accept in a given round, (ii) the number of...

Institute of Child Welfare, University of Minnesota The Wallin series of performance tests designed for use with very young children consists of four boards, each measuring 3 by 14 inches, % of an inch thick. Each board contains recesses for 6 pegs, similar in size but varying as to form. Board A includes only round pegs, Board B only square pegs, in Board C three round and three square pegs ar...

background: acute bacterial meningitis is among serious infections of the central nervous system (cns). the early diagnosis and empiric antibiotic treatments have led to a reduction in morbidity and mortality rates. pcr and the enzymatic digestion of 16s rdna fragment following the pcr by universal primers led up fast and sensitive determination. the aims of the present study was to improve our...

Introduction: When using sliding mechanics for space closure during orthodontic treatment, friction occurs at the bracket-wire interface. The aim of this study was to evaluate the frictional resistance between monocrystalline (ICE) brackets and Stainless Steel, Beta TMA and NiTi wires. Methods: In this experimental study, we used 5 different types of orthodontic wires. Brackets and wires wer...
