Abstract –– In distributed computing environments, fault–tolerance is an important objective, especially for parallel applications. Many distributed computing environments achieve fault–tolerance by periodic checkpointing. This has the advantage of relative ease of implementation and can be considered equivalent to task migration. However, there are two main disadvantages of such environments. ...

this case report presents a case of fanconi’s anemia with an unusual thumb polydactyly in a 2-year old boy. the extra thumb had no nail, nail bed and distal phalanx. the extra thumb had no active motion.the duplication of the thumb occurred at the carpometacarpal joint but its morphology did not match with any classification described for thumb polydactyly. although his thumb polydactyly was ap...

introduction: the secondary genetic changes other than the pml-rara fusion gene may contribute to the acute promyelocytic leukemogenesis. chromosomal alterations and mutation of flt3 tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia (aml). however, the prognostic significance of flt3 mutations in acute promyelocytic leukemia (apl) is not firmly established....

Analytical techniques for measuring and planning railway capacity expansion activities have been considered in this article. A preliminary mathematical framework involving track duplication and section sub divisions is proposed for this task. In railways, these features have a great effect on network performance and for this reason they have been considered. Additional motivations have also ari...

A credible theory of intelligence must provide a satisfactory account of the wide spectrum of learning abilities displayed by humans and some other animals. One of the most impressive of these is skill acquisition—the ability to create new skills, refine them through practice, and apply them in new task contexts. This ability to retain and refine solutions to important subproblems and then empl...

The simultaneous consideration of various notions (practice, procedure, prescribed task, effective task, task space, task search, task, method, activity) shows that the task accomplishment cannot be discussed at a general level, as classical approaches do. Rather, this paper points out the importance to distinguish the task definition and the task realization because the former is mainly static...

The universality of a quantum neural network refers to its ability approximate arbitrary functions and is theoretical guarantee for effectiveness. A non-universal could fail in completing the machine learning task. One proposal encode data into identical copies tensor product, but this will substantially increase system size circuit complexity. To address problem, we propose simple design dupli...

In this work, we investigate the transfer of some homological properties from a ring $R$ to its amalgamated duplication along some ideal $I$ of $R$ $Rbowtie I$, and then generate new and original families of rings with these properties.

Currarino syndrome is a rare congenital malformation characterised by the triad of: an anorectal malformation, sacral bony defect and presacral mass. One but possible anal canal duplication, anomaly which not only most distal also rarest form of digestive tract duplication. We present case four-year-old female who had complete including
