Multi-dimensional choice in DTA for example, a combined model of activity location, time of participation, duration, and route choice decisions results in exponentially increasing choice alternatives. Any efficient algorithm for solving the multi-dimensional DTA problem must avoid enumeration of alternatives. In this paper an algorithm that does not enumerate paths is presented. The algorithm i...
Developing language resources requires much time, funding and effort. This is why they need to be reused in new projects and developments, so that they may both serve a wider scientific community and sustain their cost. The main problems that prevent this from happening are that (1) language resources are rarely free and/or easy to locate; and (2) they are hardly ever interoperable. Therefore, ...
Vascular alterations are the most common causes of morbidity and mortality in diabetic patients. Despite the impact of endothelial dysfunction on microcirculatory properties, little is known about the endothelial cell alteration during the development of diabetes and its correlation to the metabolic situation. For that reason we continuously monitored in vivo functional and morphological altera...
The aim of this study was to understand the difference between the measured and calculated irradiation attenuations obtained using two algorithms and to identify the influence of couch attenuation on patient dose verification. We performed eight tests of couch attenuation with two photon energies, two longitudinal couch positions, and two rail positions. The couch attenuation was determined usi...
Glass-ceramic materials, obtained by sinter-crystallization of melted alkaline-olivine basaltic tuffs, were investigated. The kinetics of bulk crystallization was evaluated by differential thermal analysis (DTA) at different heating rates. The phase formation and the sintering behavior of glass powders (<75 lm) were studied in air and in nitrogen atmospheres by DTA and dilatometry, respectively...
Copyright © 2016 The Korean Society of Radiology As a research synthesis methodology, systematic review and meta-analysis generates an evidence-based systematic summary of a specific topic by objectively evaluating all relevant primary studies available in the literature. Metaanalysis is a part of the methodology and uses statistical methods to integrate the results of primary research studies....
Dynamic Traffic Assignment (DTA) models are important decision support tools for transportation planning and real-time traffic management. One of the biggest obstacles of applying DTA in large-scale networks is the calibration of model parameters, which is essential for the realistic replication of the traffic condition. This paper proposes a methodology for the simultaneous demand-supply DTA c...
Ligation of GITR (glucocorticoid-induced tumor necrosis factor (TNF) receptor-related gene, or TNFRSF18) by agonist antibody has recently entered into early phase clinical trials for the treatment of advanced malignancies. Although the ability of GITR modulation to induce tumor regression is well-documented in preclinical studies, the underlying mechanisms of action, particularly its effects on...
The role of charged sites on the permeability characteristics of the pulmonary microvascular barrier were investigated using chronically instrumented unanesthetized sheep. In one series of experiments we studied the effects of the cationic amphiphile, dodecyl trimethylamine (DTA; 297 mol wt), and the anionic amphiphile, SDS (288 mol wt), on lung lymph flow rates (Ql), lung lymph to plasma prote...
Particle swarm optimization (PSO) is a well-known algorithm for global optimization over continuous search spaces. However, this algorithm is limited by the intense conflict between exploration and exploitation search processes. This improper adjustment of exploration and exploitation search processes can introduce an inappropriate level of diversity into the swarm, thereby either decelerating ...
