cism misses the mark. It need only be stated that Castle was wrong in supposing that the cross-overs between yellow and white should be subtracted from the total before the white bifid cross-over value is calculated. If, as Castle states, he cannot conceive of a mechanism "which would tie two genes together in such a way that they will subsequently separate from each other oftener than they wil...

This paper presents a sampling-based planning algorithm for in-hand manipulation of a grasped object using a series of external pushes. A high-level sampling-based planning framework, in tandem with a low-level inverse contact dynamics solver, effectively explores the space of continuous pushes with discrete pusher contact switch-overs. We model the frictional interaction between gripper, grasp...

Revision : 1.148 This paper presents a taxonomy of key topi s e e ting resear h and development of distributed storage systems. The taxonomy nds distributed storage systems to o er a wide array of fun tionality, employ ar hite tures with varying degrees of entralisation and operate a ross environments with varying trust and s alability. Furthermore, taxonomies on autonomi management, federation...

Transfer RNA (tRNA) molecules play vital roles during protein synthesis. Their acceptor arms are aminoacylated with specific amino acid residues while their anticodons delimit codon specificity. The history of these two functions has been generally linked in evolutionary studies of the genetic code. However, these functions could have been differentially recruited as evolutionary signatures wer...

Scaling laws for characteristic length scales (in time or in the model parameters) are both experimentally robust and accessible for rigorous analysis. In multiscale situations cross–overs between different scaling laws are observed. We give a simple example from micromagnetics. In soft ferromagnetic films, the geometric character of a wall separating two magnetic domains depends on the film th...

Langerhans’ cell histiocytosis may cause irreversible respiratory failure due to progressive destruction of lung parenchyma and widespread cystic change. Transplantation oVers a therapeutic option. A case is described of recurrence of Langerhans’ cell histiocytosis which was associated with deterioration in lung function four years following bilateral lung transplantation. Patients transplanted...

Abstra t. We study the minimum kover problem. For a given string x of length n and an integer k, the minimum kover is the minimum set of ksubstrings that overs x. We show that the on-line algorithm that has been proposed by Iliopoulos and Smyth [IS92℄ is not orre t. We prove that the problem is in fa t NP-hard. Furthermore, we propose two greedy algorithms that are implemented and tested on di ...

Data-parallel languages, in particular HPF, provide a high-level view of operators overs parallel data structures and hide the details of data partitioning and communication. One of the most diicult issues in compiling such languages is managing irregular data-dependent par-allelism. This paper presents the study of a realistic, but non adaptive irregular application. We show that HPF can easil...
