Skeleton Memory 1884

On beta-skeleton automata with memory

A β-skeleton is a proximity undirected graph whose connectivity is determined by the parameter β . We study β-skeleton automata where every node is a finite state machine taking two states, and updating its states depending on the states of adjacent automata-nodes. We allow automata-nodes to remember their previous states. In computational experiments we study how memory affects the global spac...

Chromobodies are intracellular nanoprobes that combine the specificity of antibodies with the convenience of live fluorescence imaging in a flexible, DNA-encoded reagent. Here, we present the first application of this technique to an intact living vertebrate organism. We generated zebrafish lines expressing chromobodies that trace the major cytoskeletal component actin and the cell cycle marker...

During morphogenesis, organs grow to stereotyped sizes, but growth control mechanisms are poorly understood. Here, we measured the signaling dynamics of the morphogen Dpp, one of several Drosophila factors controlling morphogenetic growth, in the developing eye. In this tissue, the Dpp expression domain advances from the posterior to the anterior tissue edge. In front of this moving morphogen s...

Parallel Branch and Bound Skeleton Using Shared Memory

There are many combinatorial optimization problems in the world considering finding the optimal solution from finite but usually very large feasible solutions. To solve such problems, Branch and Bound (B&B) algorithms are frequently used. B&B algorithms try to avoid examining all solutions for a specified problem by discarding some obvious “bad” solutions. The problem space is divided into subs...
