We study the problem of minimizing the expected cost of binary searching for data where the access cost is not fixed and depends on the last accessed element, such as data stored in magnetic or optical disk. We present an optimal algorithm for this p

Rotaviruses are the principal known etiologic agents of severe diarrhea among infants and young children worldwide. Although a rhesus rotavirus-based quadrivalent vaccine is highly effective in preventing severe diarrhea in developed countries, in de

We evaluated the reactogenicity and antigenicity of a quadrivalent rotavirus vaccine composed of serotype 3 rhesus rotavirus (RRV) and three single-gene-substitution reassortants of RRV and human strain D (D x RRV, serotype 1), DS1 (DS1 x RRV, seroty

The median, the 0.25-percentile and the 0.75-percentile are three of the most relevant ranks in data analysis. MED2Q is a new in situ algorithm to solve this problem. It asymptotically performs an average of 2 5/8 n + o(n) comparisons when n numbers

Unbalanced multiway trees are generally impractical external data structures because of their poor space performance. In order to avoid this handicap, we have adapted the technique of partial expansions to these trees. Compared to partially expandedB

A newin situ external sorting algorithm, to be calledExtquick, is developed and its time and space performance are analysed. It is shown that Extquick performs more efficiently than similarin situ sorting algorithms based on Quicksort that appear in

The efficacy of a rhesus rotavirus vaccine (MMU 18006, serotype 3) against infantile diarrhea was evaluated by active home surveillance of a group of 320 children 1-10 months of age in Caracas, Venezuela. During a 1 year period following oral adminis

It is shown that 5n/4 plus-minus lower order terms comparisons on average are necessary and sufficient to solve the problem of finding the values of ranks immediately above and below a specified element x in a set X of size n>1. When x turns out to b

Practical text proximity problems lead to the abstract data type proximity that handles close points in the plane. Different variants and implementations of proximity are proposed and tight-complexity bounds based on information theory are derived. T

We describe algorithms for constructing optimal binary search trees, in which the access cost of a key depends on the k preceding keys which were reached in the path to it. This problem has applications to searching on secondary memory and robotics.
