Study of two‐component system with failure interaction
Naval Research Logistics Quarterly, 1985In many real-life multicomponent systems, the failure of a component has some effect on one or more of the remaining components. We consider a two-component system with a specific type failure interaction and obtain expressions for the expected cost of operating the system for both finite and infinite time.

Conductivity of two-component systems
Geophysics, 1996Abstract We present measurements and computer simulation results on the electrical conductivity of nonconducting grains embedded in a conductive brine host. The shapes of the grains ranged from prolate-ellipsoidal (with an axis ratio of 5:1) through spherical to oblate-ellipsoidal (with an axis ratio of 1:5).

Among the many regulatory schemes governing virulence potential, two-component systems have been found time and time again to play key roles. The structure-function relationships of the various domains, kinase, receiver, and HPt domains, of two-component systems are examined in this chapter, following the path of information from outside to inside a ...

Two-Component Regulatory Systems
2014Originally characterized for nitrogen regulation (NtrB-NtrC), chemotaxis (CheA-CheY-CheB), osmoregulation (EnvZ-OmpR), and regulation of phosphate uptake (PhoR-PhoB) in Escherichia coli and Salmonella typhimurium, the family of two-component systems has rapidly expanded, and new examples continue to emerge.

Inhibitors of bacterial two-component signalling systems
Expert Opinion on Investigational Drugs, 2000Bacterial two-component regulatory systems (TCS) play a pivotal role in the process of infection. These signal transduction systems enable bacterial pathogens to mount an adaptive response and cope with diverse environmental stresses, including nutrient deprivation, antibiotic onslaught and phagocytosis.

Evolutionary Characteristics of Bacterial Two-Component Systems
2012The evolution of biological systems is influenced by a number of factors and forces that have acted in different combinations at different times to give rise to extant organisms. Here we illustrate some of the issues surrounding the data-driven evolutionary analysis of biological systems in the context of bacterial two-component systems (TCSs).

Small RNAs Controlled by Two-Component Systems
2008Two-component systems (TCSs) allow bacteria to monitor diverse environmental cues and to adjust gene expression accordingly at the transcriptional level. It has been recently recognized that prokaryotes also regulate many genes and operons at a posttranscriptional level with the participation of small, noncoding RNAs which serve to control translation ...
