We provide a Hilbert-Mumford Criterion for the action of a reductive group G on a Q-factorial algebraic variety X, partially proving a conjecture stated by A. BiaÃlynicki-Birula. The result allows to construct G-invariant open subsets of X admitting a good quotient by G from certain open subsets admitting a good quotient by a maximal torus T of G. As an application, we indicate an explicit meth...

In this paper, we propose a solution to adapt the differential point rendering technique developed by Kalaiah and Varshney to implicit surfaces. Differential point rendering was initially designed for parametric surfaces as a twostage sampling process that strongly relies on an adjacency relationship for the samples, which does not naturally exist for implicit surfaces. This fact made it partic...

Objective: The aim of this study was to compare the experiential avoidance, explicit and implicit attraction beliefs in obese and normal body mass index (BMI) females. Materials and Methods: This was an analytic cross sectional study. About 400 females (between 20-43 years old) were selected from nutrition and obesity clinics by convenience sampling method. The 40 items avoidance questionnaire...

this research aimed to examine the effect of sequential stimuli technique on acquisition, retention and transfer of ocular motor sequence. first sequential stimuli, time record, response error software was designed. 60 right-handed novices (15-18 years) were divided into five groups (blocked – explicit, blocked – implicit, random – explicit, random-implicit and control). all groups performed a ...

Increasingly complex schemes for representing solvent effects in an implicit fashion are being used in computational analyses of biological macromolecules. These schemes speed up the calculations by orders of magnitude and are assumed to compromise little on essential features of the solvation phenomenon. In this work we examine this assumption. Five implicit solvation models, a surface area-ba...

A unified method for simulating multiphase flows using an exactly mass, momentum, and energy conserving Cell-Integrated SemiLagrangian advection algorithm is presented. The deforming material boundaries are represented using the moment-of-fluid method. The new algorithm uses a semi-implicit pressure update scheme that asymptotically preserves the standard incompressible pressure projection meth...

This study investigates the effect of four types of oral corrective feedback, namely, explicit elicitation, implicit elicitation, explicit recast and implicit recast on the most commonly mispronounced phonological features among Iranian EFL learners through immediate uptake and retention. Five classes were randomly categorized into four experimental groups and one control group, each with 18 in...
