The RecA protein in its functional state is in complex with single-stranded DNA, i.e., in the form of a RecA filament. In SOS induction, the RecA filament functions as a coprotease, enabling the autodigestion of the LexA repressor. The RecA filament can be formed by different mechanisms, but all of them require three enzymatic activities essential for the processing of DNA double-stranded ends....

Understanding crop phenology is fundamental to agricultural production, management, planning, and decision-making. This study used 250 m 16-day Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) time-series data to detect crop phenology across the Midwestern United States, 2007–2015. Key crop phenology metrics, start of season (SOS) and end of season (EOS), we...

We recently discovered that exposure of enterohemorrhagic Escherichia coli (EHEC) to d-serine resulted in accumulation of this unusual amino acid, induction of the SOS regulon, and downregulation of the type III secretion system that is essential for efficient colonization of the host. Here, we have investigated the physiological relevance of this elevated SOS response, which is of particular i...

Electrical power system operators (SOs) are free to realize grid operations according their own strategies. However, because resulting flows also depend on the actions of neighboring SOs, appropriate coordination is needed improve states from an overall perspective and individual SO perspective. In this paper, a new method presented that preserves data integrity SOs independent operation grids....

An important characteristic of a System of Systems (SoS) is interoperability among its constituent systems. It enables the flow of information and the seamless introduction of new systems into the SoS. But interoperability comes at a price. Current studies indicate that there is significant engineering effort involved in making systems interoperable. However, this feature is not adequately repr...

1174 I n order to survive in various environmental conditions, cells have a repertoire of genes that they can choose to express or silence according to their needs. Among this vast collection of genetically controlled networks, the SOS response is an inducible DNA repair system that allows bacteria to survive sudden increases in DNA damage. The importance of the SOS response is underscored by t...

Selenium is an essential nutrient with diverse physiological functions, and soluble organic selenium (SOS) sources have a higher bioavailability than inorganic selenium sources. Based on the response surface methodology and central composite design, this study presents the optimal medium components for SOS accumulation in batch cultures of Flammulina velutipes, i.e. 30 g/L glucose, 11.2 mg/L so...

This position paper on the (meta-)theory of Structural Operational Semantic (SOS) is motivated by following two questions: (1) Is SOS dying out as a research field? (2) If so, it possible to rejuvenate this field with redefined purpose? In article, we will consider answers those questions first analysing history EXPRESS/SOS workshops and data concerning authors presentations featured in edition...

OBJECTIVES To define the target population of patients who have suspicion of sepsis (SOS) and to provide a basis for assessing the burden of SOS, and the evaluation of sepsis guidelines and improvement programmes. DESIGN Retrospective analysis of routinely collected hospital administrative data. SETTING Secondary care, eight National Health Service (NHS) Acute Trusts. PARTICIPANTS Hospita...

During the first ten years of the SOS program, the major focus in research was on regional oxidant (especially ozone) pollution and the earliest objectives were to identify ozone-related chemical and meteorological factors that were unique to the SOS region – such as the large quantities of biogenic VOC emissions, greater frequencies of air stagnation days, and abundant NOx-producing lightning ...
