Abstract:
An exact hierarchy of equations for atomic averages is constructed for a multicomponent super-radiative system. By an example of a two-component system it is shown that the correlations between components arising from the interaction with a common field of radiation change the process qualitatively in comparison with the case of two independent components. In particular, two successive super-radiation pulses may appear in the system that initially had only one excited component.

Abstract:
The design of a system, for reliability purposes, often requires the exact expression of its reliability function, which, however, is seldom available in closed form. Approximate methods are non-optimal and could even lead to errors. For two-component systems, with independent Gamma-distributed components, it is shown here that we can accurately determine the second component, within various configurations, when the first component is supposed known. Both classical and Bayesian approaches are considered.

Abstract:
<abstract><p>This article studies a parallel repairable degradation system with two similar components and a repairman who can take a single vacation. Suppose that the system consists of two components that cannot be repaired "as good as new" after failures; when the repairman has a single vacation, the fault component of system may not be repaired immediately, namely, if a component fails and the repairman is on vacation, the repair of the component will be delayed, if a component fails and the repairman is on duty, the fault component can be repaired immediately. Under these assumptions, a replacement policy $ N $ based on the failed times of component 1 is studied. The explicit expression of the system average cost rate $ C(N) $ and the optimal replacement policy $ N^{\ast} $ by minimizing the $ C(N) $ are obtained, which means the two components of the system will be replaced at the same time if the failures of component 1 reach $ N^{\ast} $. To show the advantage of a parallel system, a replacement policy $ N $ of the cold standby system consisting of the two similar components is also considered. The numerical results of both systems are given by the numerical analysis. The optimal replacement policy $ N^* $ for both systems are obtained. Finally, the comparison of numerical results shows the advantages of the parallel system.</p></abstract>

Abstract:
AbstractBased on the KP hierarchy reduction method, we construct the general bright-dark mixed N-soliton solution of the two-dimensional (2D) (M+1)-component Maccari system comprised of M-component short waves (SWs) and one-component long wave (LW) with all possible combinations of nonlinearities. We firstly consider two types of mixed N-soliton solutions (two-bright-one-dark and one-bright-two-dark solitons in SW components) to the (3+1)-component Maccari system in detail. Then by extending our analysis to the (M+1)-component Maccari system, its general m-bright-(M–m)-dark mixed N-soliton solution is obtained. The formula obtained also contains the general all-bright and all-dark N-soliton solutions as special cases. For the two-bright-one-dark mixed soliton solution of the (3+1)-component Maccari system, it can be shown that solioff excitation and solioff interaction take place in the two SW components supporting bright solitons, whereas the SW component supporting dark solitons and the LW component possess V-type solitary and interaction.

Abstract:
Operational systems deteriorate over time and eventually fail by the failure of one or more of their components. Failed components are either replaced or repaired, and replacement is usually expensive. This article examines the behavior of repairable systems with imperfect repair, where a failed component is repaired once or more depending on factors such as repair cost, level of deterioration, and criticality of the component. When these systems are subjected to a customer use environment, their performance must endure different conditions. In imperfect repair, the performance of the system lessens after each failure. Three models of a two-component system studied are the series, parallel, and standby configurations, and the components are identical and independent. A closed form analytical expression for steady state operational probability is derived for different configurations under exponential distribution time to failure and repair time. Two examples are then discussed thoroughly.

Abstract:
Os sistemas de sinalização de dois componentes são sistemas prevalentes em bactérias, permitindo a adaptação a diferentes condições ambientais. O sistema de dois componentes classicamente possui uma proteína histidina quinase, o primeiro componente, capaz de reconhecer o estímulo ambiental e fosforilar o regulador de resposta, o segundo componente. Pseudomonas aeruginosa é uma proteobactéria ubíqua, capaz de infectar hospedeiros filogeneticamente distintos. Esse patógeno oportunista apresenta um dos maiores conjuntos de sistemas de dois componentes em bactérias, que permite que ela sobreviva numa grande gama de ambientes, incluindo humanos. P. aeruginosa UCBPP-PA14 apresenta pelo menos 64 histidina quinases e 76 reguladores de resposta codificados em seu genoma. Diversos sistemas de dois componentes já foram correlacionados com a virulência, sendo o sistema GacSA o exemplo melhor caracterizado. Há poucos estudos sistemáticos sobre o envolvimendo dos reguladores de resposta na virulência de P. aeruginosa e os sinais que induzem a ativação dos reguladores de resposta precisam ser encontrados. Para identificar novos reguladores de resposta envolvidos na patogenicidade, infecções in vitro em macrófagos e in vivo em Drosophila melanogaster foram realizadas neste trabalho. Os macrófagos foram infectados com cada mutante dos reguladores de resposta ou com a linhagem selvagem, e a produção da citocina pró-inflamatória TNF-α e o clearance bacteriano foram determinados. Alternativamente, as moscas foram infectadas utilizando-se a estratégia de feeding e a sobrevivência foi verificada. Utilizando-se essas abordagens, a identificação de diversos reguladores de resposta com papel na virulência foi alcançada, além de se corfirmar o papel de reguladores de resposta já estudados. Um dos novos genes envolvidos em virulência, PA14_26570 (nomeado neste trabalho de atvR), codifica um regulador de resposta atípico com substituição no aspartato fosforilável para glutamato, o que usualmente induz um estado sempre ativo. Um mutante não polar em atvR foi construído e macrófagos infectados com a linhagem ΔatvR confirmaram um maior clearance bacteriano e maior produção de TNF-α em comparação aos macrófagos infectados com a linhagem selvagem. Para comprovar a participação de AtvR durante a patogênese, um modelo de pneumonia aguda em camundongos foi utilizado. Camundongos infectados com a linhagem ΔatvR apresentaram uma maior sobrevivência em comparação aos camundongos infectados com a linhagem selvagem. Além disso, os camundongos infectados com ΔatvR apresentaram menor carga bacteriana, aumento no recrutamento de neutrófilos ativados e aumento na produção de citocinas pró-inflamatórias (TNF-α e IFN-γ). Utilizando-se uma abordagem transcritômica (RNA-Seq), foi determindo diversos genes são regulados positivamente na linhagem superexpressando AtvR em relação à linhagem controle. Dentre esses, os clusters de respiração anaeróbia nar, nir, nor e nos estão incluídos. Esse resultado foi confirmado por qRT-PCR e análises fenotípicas, em que a linhagem ΔatvR apresentou menor crescimento e expressão da nitrato redutase durante condições de hipóxia em comparação à linhagem selvagem. Em suma, neste trabalho foi demonstrado que diversos reguladores de resposta são importantes para a virulência de P. aeruginosa em macrófagos in vitro e in vivo em Drosophila, além de caracterizar o regulador de resposta atípico AtvR, que regula a respiração anaeróbica por desnitrificação, permitindo que P. aeruginosa possa infectar e colonizar o hospedeiro com maior eficiência.
Two-component systems are widespread in bacteria, allowing the adaptation to environmental changes. A two-component system is classically composed by a sensor kinase that phosphorylates a cognate response regulator. Pseudomonas aeruginosa is a ubiquitous proteobacterium able to cause disease in several hosts. This opportunistic pathogen presents one of the largest sets of two-component systems known in bacteria, which certainly contributes to its ability to thrive in a wide range of environmental settings, including humans. P. aeruginosa UCBPP-PA14 genome codes for at least 64 sensor kinases and 76 response regulators. Some response regulators are already known to be related to virulence, with the GacSA system as the best characterized. There are no systematic studies about the involvement of P. aeruginosa response regulators in virulence. Moreover, the input signal that triggers the response regulator activation is yet to be uncovered for most systems. To find new response regulators involved in virulence, in vitro infections werecarried out using macrophages. Briefly, the macrophages were infected with each response regulator mutant or the wild-type strain, the pro-inflammatory cytokine production (TNF-α) and the bacterial clearance were evaluated. Using this approach, we identified several response regulators involved in virulence, and we also confirmed the involvement of known response regulators in this process. One of the novel virulence-related response regulators, PA14_26570 (named here as AtvR), is an atypical response regulator with a substitution in the phosphorylable aspartate to glutamate, that usually leads to an always-on state. A non-polar mutant was constructed, and macrophage infection with ΔatvR confirmed an increased bacterial clearance as well as a higher TNF-α production as compared to the wild-type strain. To ascertain the role of AtvR during the pathogenic process, an acute pneumonia model was used. Mice infected with ΔatvR showed an increased survival as compared to mice infected with the wildtype strain. In addition, ΔatvR infected mice showed reduced bacterial burden, increased neutrophil recruitment and activation, as well as increased pro-inflammatory cytokine production (TNF-α and IFN-γ). Also, using a transcriptomic approach (RNASeq), we showed that several genes were upregulated in the strain overexpressing AtvR. These genes include the anaerobic respiration clusters nar, nir, nor and nos. This result was confirmed by qRT-PCR and phenotypic analysis, in which ΔatvR showed reduced growth and nitrate reductase expression during hypoxic conditions as compared to the wild-type strain. In conclusion, we have demonstrated that several response regulators are important for P. aeruginosa virulence in vitro. In addition, we further characterized the atypical response regulator AtvR, which regulates anaerobic respiration via denitrification, allowing this bacterium to infect and colonize the host more efficiently.

Abstract:
The gram-positive bacterium Streptococcus sanguinis is a member of human indigenous oral microbialflora and has long been recognized as a key player in the bacterial colonization of the mouth. S. sanguinis is also the most common viridians streptococcal species implicated in infective endocarditis. Although many studies have focused on two-component systems in closely related Streptococcus species such as S. mutans, S. pneumoniae and S. gordonii; the mechanism of the response regulator in S. sanguinis is still unknown. The ability of S. sanguinis to adapt and thrive in hostile environments suggests this bacterium is capable of sensing and responding to various environmental stimuli. The present study clearly demonstrates that a number of RR genes, SSA_0204, SSA_0217, SSA_1810, SSA_1794, and SSA_1842, in S. sanguinis are essential to the recognition and response to various environmental stresses. Results from this study also identified genes SSA_0260, SSA_0261, and SSA-0262, involved in acidic tolerance and suppressed by SSA_0204 response regulator.

Full text
Abstract:
VanS and VanR form the two-component regulatory system that controls inducible glycopeptide resistance in Enterococci. Upon induction VanS, a sensor histidine kinase, phosphorylates itself on a conserved histidine residue. This phosphate is transferred to a conserved aspartate residue on VanR. The phosphorylated form of VanR is the transcriptional activator of the vanAHX genes which, when expressed, directly confer vancomycin resistance. VanS also possesses VanR phosphatase activity, providing a mechanism by which to repress vanAHX transcription. This thesis describes approaches used towards the crystallisation of VanS and VanR. These are based upon previous crystallisation studies resulting in full-length VanS crystals which diffracted to 8Å, as well as a cytoplasmic structure of an analogous histidine kinase from Thermatoga maritima (Marina et al., 2005). Full-length and truncated forms of VanSA and full-length VanRA were cloned, expressed in E.coli and purified for crystallisation studies. Autokinase activity was biochemically characterised using radiolabelling and spectrophotomic assays, in tandem with a novel application of mass spectrometry. Site-directed mutagenesis of VanSA, led to the observation that ATP hydrolysis may occur independently of the autokinase function of VanSA. Adenosine 5’ tetraphosphate was also discovered, as a novel product of VanSA. Based upon these data an expanded model for VanS autokinase activity has been proposed. This may be expanded to include the phosphotransfer and phosphatase mechanisms and validated through the measurement of associated product formation. Finally a new mechanism for the control of the VanRS two component system has been proposed. Future studies will validate and expand this model. This work has significantly increased our knowledge of this system providing the tools and foundations that will lead to the elucidation of the way that this two component system functions. This has the potential for the development of novel inhibitors that either complement or supersede existing therapies.

Full text
Abstract:
Studies were undertaken to clone and characterise a two-component regulatory system from a clinical isolate (204) of the human and animal pathogen Burkholderia pseudomallei. A number of genomic libraries were constructed in E. coli host-vector systems and screened for the presence of a two-component system using oligonucleotide probes based on nucleotide sequence homology. Fragments of genomic DNA were cloned and sequenced and found to possess two open reading frames (ORFs) that overlap with a single nucleotide and are believed to encode a novel two-component regulatory system. A possible promoter region was identified upstream of the two ORFs, mrgR and mrgS, which read in the same direction and may represent an operon. The deduced translation of mrgR reveals a protein, MrgR, which possesses conserved motifs that are consistent with the phosphorylation domains and DNA-binding helix-turn-helix structure of a family of response regulatory proteins. The deduced translation of mrgS reveals that the MrgS protein possesses all the invariant amino acids that characterise other sensor regulatory proteins. Southern hybridisation studies showed that the mrgRS locus was present in 19 isolates of B. pseudomallei from a wide geographical derivation, but not in any closely related bacterial species, including Burkholderia thailandensis. The expression of the two genes was verified using antibodies developed to synthetic peptides based on sequences from the C- and N-terminal regions of MrgR and MrgS, respectively. The specificity of the antibodies was confirmed in Western blotting studies in which almost all of mrgR and the proximal quarter of mrgS were translationally fused with malE (MBP-MrgR and MBP-MrgS) and expressed in E. coli K12. The antibodies were used to probe Western blots of cellular and extracellular extracts of different isolates of B. pseudomallei and identified multiple bands in whole-cell lysates. The sizes of two of these bands were 24 kDa and 115 kDa, which may represent the unprocessed forms of MrgR and MrgS, respectively. It was proposed that the other bands represented either isoforms or degradation products of the full-length proteins. The recognition of all bands was abolished following pre-incubation of the antibodies with the immunising peptide but remained unaffected if an irrelevant peptide, was used for this purpose. Western blot analysis demonstrated that serum antibodies from a patient with acute melioidosis recognised MBP-MrgR but not MBP-MrgS suggesting a possible role for MrgR in the disease process. The expression of mrgR and mrgS was found to be constitutive in B. pseudomallei that had been cultured using different combinations of temperature, pH and NaCl suggesting that the genes perform a number of biological functions. There is some evidence that at 42°C the processing of MrgR and MrgS may be altered and the possible mechanisms for this are discussed. B. pseudomallei grew better at 42°C and pH 5 and less well at 25°C and pH 8 and this was influenced by NaCl concentration partly reflecting the environmental distribution and intracellular nature of the pathogen. Environmental and clinical isolates of B. pseudomallei differed in the pH optimum for growth at 42°C. The DNA flanking the mrgRS locus in isolate 204 was cloned, sequenced, and seven ORFs were identified including a transcriptional regulatory gene similar to bvgR of Bordetella pertussis. Southern blot analysis using three different DNA probes revealed restriction fragment length polymorphisms (RFLPs) in the region downstream of mrgRS. Two distinct RFLP patterns were identified among 16 different isolates of B. pseudomallei. The potential effects of this variation on gene expression and protein function await further investigation.

Full text
Abstract:
Two-component signal transduction systems (TCS) consist of a sensor histidine kinase and a response regulator. TCS are ubiquitous in prokaryotes, but found only in some eukaryotes. TCS mediate adaptation to various environmental changes in bacteria, plants, fungi, and protists. Histidine kinase 2 (Hik2) is a sensor histidine kinase found in all cyanobacteria. The Hik2 homologue known as Chloroplast Sensor Kinase is found in algae and plants, where it is encoded by the nuclear genome and it is targeted to chloroplasts. CSK couples the redox state of the photosynthetic electron transport chain to chloroplast gene transcription. This thesis describes biochemical characterisation of the signal transduction mechanism of Hik2 and its response regulator (Rre) partners in order to clarify the Hik2-Rre two-component signal transduction pathway. Results presented in this thesis illustrate that the autophosphorylation activity of the full-length Hik2 protein is specifically inhibited by sodium ions. An autophosphorylation event of a histidine kinase is the result of homodimerisation and is followed by trans or cis-autophosphorylation of each monomer on its conserved histidine residue. Chemical crosslinking revealed that the Hik2 protein exists predominantly as a phosphorylated (autokinase active) monomer, tetramer, and higher-order oligomeric complexes. The functions of these different oligomeric states of Hik2 are also discussed. From a previous study, which was based on an observation from a yeast two-hybrid assay, Hik2 was proposed to form a two-component pair with Rre1 and RppA. However, no further evidence was presented to support either direct interaction or direct phosphotransfer activity of the Hik2-Rre pair. This thesis confirms interaction of Hik2-Rre1 and Hik2-RppA two-component ! %! pairs using an in vitro pull-down assay and phosphotransfer kinetics. Finally, a model is proposed for the Hik2 based two-component signal transduction pathway.

Juni, Sarkar. "Characterization of Hpk2-Rrp2, two-component regulatory system in Treponema denticola." VCU Scholars Compass, 2011. http://scholarscompass.vcu.edu/etd/268.

Full text
Abstract:
Treponema denticola levels in the gingival crevice become elevated as periodontal disease develops. Oral treponemes may account for as much as 40% of the total bacterial population in the periodontal pocket. The stimuli that trigger enhanced growth of T. denticola and the mechanisms associated with the transmission of these signals remain to be defined. A hypothesis was set that the T. denticola ORFs tde1970 (histidine kinase) and tde1969 (response regulator) constitute a functional two component regulatory system that regulates, at least in part, responses to the changing environmental conditions associated with the development of periodontal disease. The results presented demonstrate that tde1970 and tde1969 are conserved, universal among T. denticola isolates and transcribed as part of a 7 gene operon in a growth phase dependent manner. Tde1970 undergoes autophosphorylation and transfers phosphate to Tde1969. Henceforth the proteins encoded by these ORFs are designated as Hpk2 and Rrp2 respectively. Hpk2 autophosphorylation kinetics was influenced by environmental conditions and by the presence or absence of a Per Arnt Sim (PAS) domain. It can be concluded that Hpk2 and Rrp2 constitute a functional two-component system that contributes to environmental sensing. This study also sought to determine the molecular basis of Hpk2 function in response to environmental stimuli. Hpk2 was shown to bind hemin via a putative heme-binding domain within the PAS domain. Hemin binding to Hpk2 positively regulated its autokinase ability under anaerobic conditions, suggesting that Hpk2 activation may play a role in the migration of T. denticola away from the aerobic zone deeper into developing periodontal pockets. In this study we have generated point mutations of conserved amino acid residues in the sensor PAS domain of Hpk2 and assessed their role in kinase activation under both aerobic and anaerobic conditions depending on their oligomeric state, hence providing a strong basis to correlate ligand binding, kinase activity and oligomeric states of the protein that may provide stability of these complex interactions. Ultimately this study provides a comparative linkage between the responses of PAS domain to sensory inputs controlling access to its kinase domain within which is contained the dimerization domain, which ultimately leads to fine-tuned control of interactions between Hpk2 dimerization and catalytic domain.

The basic factors are considered such as the natural conditions and the production apparatus of the region, the development of a program-oriented approach to the development of the territory and the formation of the material base of railway transport in its space. These components are considered as historical challenges for the design of labor initiatives "from below". These initiatives are classified into three groups: speeding up the turnover of wagons, using the locomotive fleet, and saving fuel, energy, and other" variable " resources of the railway transportation process. The issues are considered taking into account the trends of fading opportunities for the Soviet model of system-wide development. It will be of interest to all those who are concerned about the history of Russia, the organization of its transport security system.

Abstract:
The lymphatic vascular system is an integral component of the circulatory system; it forms a one-way conduit that transports tissue interstitial components back to the venous circulation through lymph nodes. Lymphatic vessels extend to most tissues and contribute to the regulation of interstitial fluid homeostasis, trafficking of immune cells, and absorption of dietary fats from the gut. Developmentally, lymphatic vessels originate from embryonic veins and specialized angioblasts. A number of molecules have been identified in the commitment of endothelial cells to the lymphatic lineage, and the sprouting, expansion and maturation of the lymphatic vascular tree. Importantly, the vascular endothelial growth factor (VEGF) family members VEGFC and VEGFD, together with their receptors VEGFR2 and VEGFR3 have been implicated as critical regulators of lymphangiogenesis. Lymphatic vessels are involved in several human diseases, including cancer, where they contribute to tumour metastasis, the leading cause of cancer-related deaths. Lymphatic vessels regulate immune responses against foreign pathogens by transporting leucocytes to lymph nodes, but are also in involved in the regulation of self-tolerance. Defects in the lymphatic vascular system are causal for the development of lymphoedema.

Abstract:
The Rapid Response System (RRS) is organized into four basic components. These components include an activation limb, a response limb, a quality assurance infrastructure, and an administrative component. These components remain consistent despite campus size, physical layout, patient population, available technical resources, and personnel. Oversight of the RRS is provided by the patient safety, risk management experts, as well as clinical experts to maintain high quality of care delivered to acutely ill patients. Administrative support in the development of policy, allocation of resources, and communicating a strong and clear message regarding the mission and vision of the RRS is invaluable. In this chapter, we review each element of the RRS.

Abstract:
Abstract Component Mode Synthesis (CMS) is a dynamic substructuring technique for approximate eigensolutions of large degree-of-freedom systems divisible into two or more components. System synthesis using component modes results in approximate eigenparameters. The approximation is improved by using more component modes in synthesis. Typically, all component modes up to x times the frequency range of interest are required to assure reasonable accuracy, where x varies from 2 to 10. This paper demonstrates the two-step CMS approach, wherein, the first step involves system synthesis using the minimum number of component modes (x∼1) required to obtain approximate eigenvalues up to a preselected frequency and the second step uses additional component modes in a convergence scheme operating on the system eigenparameters calculated in the first step. Results of studies on spring-mass systems, beam and plate models, and a refrigeration compressor assembly show that the two-step method provides the analyst some insight into the convergence and accuracy of the eigenparameters without resolving the system over and over with more component modes. The method is also efficient in terms of solution time, when compared to conventional CMS using the Jacobi method and the subspace-iteration method.

Abstract:
The US Army Corps of Engineers (USACE) operates, maintains, and manages more than $232 billion worth of the Nation’s water resource infrastructure. Using the Operational Condition Assessment (OCA) system, the USACE allocates limited resources to assess conditions and maintain assets in efforts to minimize risks associated with asset performance degradation. Currently, OCAs are conducted on each component within a facility every 5 years, regardless of the component’s risk contribution. The analysis of risks associated with Flood Risk Management (FRM) facilities, such as dams, includes considering how the facility contributes to its associated FRM watershed system, understanding the consequences of degradation in the facility’s performance, and calculating the likelihood that the facility will perform as expected given the current OCA condition ratings of critical components. This research will develop a scalable methodology to model the probability of failure of components and systems that contribute to the performance of facilities in their respective FRM systems combined with consequences derived from hydrological models of the watershed to develop facility risk scores. This interim report documents the results of the first phase of this effort, stakeholder analysis and literature review, to identify candidate approaches to determine the probability of failure of a facility.

Full text
Abstract:
Using Colombian credit vintage data, we decompose the non-performing loans into one component that captures the evolution of the payment capacity of borrowers, and other component that captures changes in the credit risk taken by the financial system at the time of loan disbursement. We use intrinsic estimators and penalized regression techniques to overcome the perfect multicollinearity problem that the model entails. We find that these two type of components have evolved differently over time, and that good economic conditions and loose financial conditions improve the payment capacity of borrowers to meet their obligations, and in turn, they tend to coincide with the financial system engaging in riskier loans. Finally, we advocate the use of this methodology as a policy tool that is easy to apply by financial and economic authorities that dispose of a constant flow of credit vintage information. Through it, they will be able to identify the origin of the credit risk materialization and curb the risk taken by the financial system.
