We present a novel algorithm for collision detection between two discretely oriented polytopes (k-DOPs). It is an application of the well known Separating Axes Test to k-DOPs and is implemented in fixed-point arithmetic. Hence, it lends itself very well to hardware implementation. In this report we focus on the derivation of the algorithm and an error-bound on the rounding-error produced by the...

High-resolution small-angle X-ray scattering (SAXS), complemented by small-angle neutron scattering (SANS) and dynamic light scattering (DLS) experiments, was used to study the effect of curvature on the bilayer structure of dioleoyl-phosphatidylcholine (DOPC) and dioleoyl-phosphatidylserine (DOPS) unilamellar vesicles (ULVs). Bilayer curvature, as a result of finite vesicle size, was varied as...

Introduction: Nowadays according to competency basedcurriculum, selecting an appropriate assessment method isinevitable. This study aimed to investigate application of DirectObservation of Procedural Skills (DOPS) in undergraduatemedical students.Methods: This is a cross sectional study conducted duringemergency ward rotation in last year medical students usingconsensus sampling method. Each st...

AIM To evaluate the impact of two different assessment formats on the approaches to learning of final year veterinary students. The relationship between approach to learning and examination performance was also investigated. METHOD An 18-item version of the Study Process Questionnaire (SPQ) was sent to 87 final year students. Each student responded to the questionnaire with regards to DOPS (D...

A remarkable flexibility is observed in biological membranes, which allows them to form the structures of different curvatures. We addressed the question of intrinsic ability of phospholipid membranes to form highly curved structures and the role of cholesterol in this process. The distribution of cholesterol in the highly curved asymmetric DOPC/DOPS lipid bilayer was investigated by the coarse...

In recent years, there has been a growing interest in studying evolutionary algorithms (EAs) for dynamic optimization problems (DOPs). Among approaches developed for EAs to deal with DOPs, immigrants schemes have been proven to be beneficial. Immigrants schemes for EAs on DOPs aim at maintaining the diversity of the population throughout the run via introducing new individuals into the current ...

A Ponte da Amizade, localizada na região Tríplice Fronteira (Argentina, Brasil e Paraguai), é a principal travessia entre o Paraguai desde as décadas finais do século XX.
