The SOS response of bacteria is a global regulatory network targeted at addressing DNA damage. Governed by the products of the lexA and recA genes, it co-ordinates a comprehensive response against DNA lesions and its description in Escherichia coli has stood for years as a textbook paradigm of stress-response systems in bacteria. In this paper we review the current state of research on the SOS ...

SOS (SOMIW Operating System) is the result of a four-year effort at INRIA to define an object-oriented operating system. SOS provides support for arbitrary, user-defrned, typed objects. The system implements object migration; this mechanism is generic, but can be tailored to specific object semantics thanks to the prerequisite and upcall concepts. SOS also supports Fragmented Objects (FOs), i.e...

Software systems have evolved from being stand-alone systems to being composed into Systems of Systems. A System of Systems (SoS) is defined as an arrangement of independently created, discovered, and selected systems, which are integrated into a single system in order to deliver unique capabilities [1]. In this context, each participating system can operate and support different goals in its o...

A system-of-systems (SoS) is a large information processing system formed by the integration of autonomous computer systems (called constituent systems, CS), physical machines and humans for the purpose of providing new synergistic services and/or more efficient economic processes. In a number of applications, e.g robotics, the autonomous CSs must coordinate their actions in the temporal domain...

The paper is devoted to one of the practical approaches to manage complex projects. A case study of complex project management is described. This concerns transforming a Russian IT-company into an enterprise system and system of systems (ES/SoS) at the same time. Main elements of the transformation – the goal, solution, structure, and relations among constituents of ES/SoS, ES/SoS engineering p...

Relaxation times (T(1) and T(2)) of the bone marrow protons and trabecular bone volume fraction (TBVF) in the calcaneus were measured for 100 female volunteers using a compact MRI system at 0.2 T field strength. The speed of sound (SOS) through the calcaneus was measured also for the same subjects using a quantitative ultrasound system. Both relaxation times were found to have positive correlat...

Sinusoidal obstruction syndrome (SOS; formerly veno-occlusive disease) is a well-established complication of hematopoietic stem cell transplantation, pyrrolizidine alkaloid intoxication, and widely used chemotherapeutic agents such as oxaliplatin. It is associated with substantial morbidity and mortality. Pathogenesis of SOS in humans is poorly understood. To explore its molecular mechanisms, w...

Structured Operational Semantics (SOS) is a popular method for defining semantics by means of transition rules. An important feature of SOS rules is negative premises, which are crucial in the definitions of such phenomena as priority mechanisms and time-outs. However, the inclusion of negative premises in SOS rules also introduces doubts as to the preferred meaning of SOS specifications. Order...

System-of-systems (SoS) architecture is crucial in managing complex and interconnected systems. However, the description modeling of SoS pose significant challenges require a structured organized approach. In this study, metamodel for that considers both structural behavioral perspectives defined. The then mapped to ontologies are enhanced with flow-based extension characterize views. On basis,...

Sotos syndrome (Sos) is an overgrowth disorder also characterized clinically by mental retardation, specific craniofacial features and advanced bone age. As NSD1 haploinsufficiency was determined in 2002 to be the major cause of Sos, many intragenic mutations and chromosomal microdeletions involving the entire NSD1 gene have been described. In the Japanese population, half of the cases analyzed...
