BACKGROUND Resistance to commonly used antituberculosis drugs is emerging worldwide. Conventional drug-susceptibility testing (DST) methods are slow and demanding. Alternative, rapid DST methods would permit the early detection of drug resistance and, in turn, arrest tuberculosis transmission. METHODS A cost-effectiveness analysis of 5 DST methods was performed in the context of a clinical tr...
Investigators continue to debate whether the Dexamethasone Suppression Test (DST) reflects clinical severity or degree of melancholia ("endogeneity"). To evaluate this question, we studied 73 drug-free inpatients diagnosed with Schedule for Affective Disorders and Schizophrenia/Research Diagnostic Criteria (SADS/RDC) as having major depressive disorder (MDD). We compared absolute and dichotomou...
erated interest and excitement in psychological research, as demonstrated by the recent statement, “...the dynamical perspective has emerged as a primary paradigm for the investigation of psychological processes at different levels of personal and social reality” (Vallacher et al., 2010, p. 263). What is less clear to the authors is the degree to which this excitement is justified. Like many ps...
In dynamic world that the continuous change is its fixed laws, important parts of higher education and university as small world in major society in form of conservative institutions in compared with power, culture, government and industry, have stayed approximately static. In compared with first decades of the second half of the last century that university become valid social institutions, it...
There are several factors causing fastening systems to deteriorate faster than the designed life. The high repetitive loads from a moving train being one of the main factors, track irregularities, design and installation defects of track components, non-uniform rail support stiffness, unevenness in the rail seat deterioration are some of the factors causing fastenings systems to deteriorate fas...
Multiple criteria decision-making (MCDM) based on interval intuitionistic fuzzy value (IVIFV) is a process of aggregating decision represented by multiple interval-valued numbers to select the optimal alternative. Among them, an aggregation operator indispensable tool, and properties directly affect results. Existing operators IVIFV have satisfactory results in eliminating correlation between r...
In this research, a functionally graded microbeam bonded with piezoelectric layers is analyzed under electric force. Static and dynamic instability due to the electric actuation is studied because of its importance in micro electro mechanical systems, especially in micro switches. In order to prevent pull-in instability, two piezoelectric layers are used as sensor and actuator. A current amplif...
rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. in the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. with traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. four s...
BACKGROUND Even though the WHO-endorsed, non-commercial MODS assay offers rapid, reliable TB liquid culture and phenotypic drug susceptibility testing (DST) at lower cost than any other diagnostic, uptake has been patchy. In part this reflects misperceptions about in-house assay quality assurance, but user convenience of one-stop procurement is also important. A commercial MODS kit was develope...
In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system. A...
