چکیده

The vertebrate central nervous system contains a great diversity of neurons and glial cells, which are generated in the embryonic neural tube at specific times and positions. Several classes of transcription factors have been shown to control various steps in the differentiation of progenitor cells in the neural tube and to determine the identity of the cells produced. Recent evidence indicates that combinations of transcription factors of the homeodomain and basic helix-loop-helix families establish molecular codes that determine both where and when the different kinds of neurons and glial cells are generated.

Services, Enablers and Architectures: Definition of a connected Web 2.0 / Telco Service Broker to enable new flexible Service Exposure Models

Modern telecommunication networks and classical roles of operators are subject to fundamental change. Many network operators are currently seeking for new sources to generate revenue by exposing network capabilities to 3rd party service providers. At the same time we can observe that applications on the World Wide Web (WWW) are becoming more mature in terms of the definition of APIs that are of...

MASH-1/RET pathway involvement in development of brain stem control of respiratory frequency in newborn mice.

Respiratory abnormalities have been described in MASH-1 (mammalian achaete-scute homologous gene) and c-RET ("rearranged during transfection") mutant newborn mice. However, the neural mechanisms underlying these abnormalities have not been studied. We tested the hypothesis that the MASH-1 mutation may impair c-RET expression in brain stem neurons involved in the control of breathing. To do this...

Smashing MASH-1

MASH-1 is modular arithmetic based hash function. It is presented in Part 4 of ISO/IEC 10118 standard for one and a half decade. Cryptographic strength of MASH-1 hash function is based on factorization problem of an RSA modulus along with redundancy in the input blocks of compression functions. Despite of this, we are able to introduce two large classes of moduli which allow practical time coll...

Declaratively Producing Data Mash-ups

Mash-ups extract data fragments from disparate sources, and combine and transform the extracted fragments for display. Currently, mash-up developers tend to employ ad hoc representations for mash-up data, view mash-ups as applications, and use imperative scripts to extract and transform data fragments. These approaches can make mash-up development hard, and the mash-ups’ run-time performance po...
