Computational tools for normal mode analysis, which are widely used in physics and materials science problems, are designed here in a single package called NMscatt (Normal Modes & scattering) that allows arbitrarily large systems to be handled. The package allows inelastic neutron and X-ray scattering observables to be calculated, allowing comparison with experimental data produced at large sca...

Objectives To estimate the prevalence of time-to-event (TTE) outcomes in cluster randomized trials (CRTs) and to examine their statistical management. Study design setting We searched PubMed identify primary reports CRTs published six major general medical journals (2013–2018). Nature and, for TTE outcomes, methods sample size, analysis, measures intracluster correlation were extracted. Results...

Breadth-first ray tracing is based on the idea of exchanging the roles of rays and objects. For scenes with a large number of objects, it may be profitable to form a set of rays and compare each object in turn against this set. By doing so, thrashing, due to disk access, can be minimized. In this paper, we present ways to combine breadth-first methods with traditional efficient algorithms, alon...

This paper aims at investigating the nonlinear behavior of a system which is consisting of two free-free beams which are connected by a nonlinear joint. The nonlinear system is modelled as an in-extensional beam with Timoshenko beam theory. In addition, large amplitude vibration assumption is taken into account in order to obtain exact results. The nonlinear assumption in the system necessities...

Traditionally. the syntax-semantics interface has been characterized by the projection of verb arguments onto the level of syntax based on (lexical semantic) information associated with the verb (Jackendoff, 1990; Levin, 1993; Van Valin, 1993). The assumption in current approaches is that the rules linking arguments to syntactic positions are universal. This implies that verbs with similar lexi...

High frequency methods resort to numerical ray tracing for application to complex environments. A new method based on the geometrical projection performed by a ray-congruence has been developed as a preconditioning of the ray tracing procedure. It builds a visibility tree, i.e., a database, storing information on all possible ray paths inside a scenario. The method gives a solution to a class o...
