This paper presents our numerical results for the application of the Isogeometric Analysis (IGA) to the velocity-pressure formulation of the steady state as well as the unsteady incompressible Navier-Stokes equations. For the approximation of the velocity and pressure fields, LBB compatible spline spaces are used which can be regarded as generalizations of Taylor-Hood pairs of finite element sp...

This article presents uniform B-spline interpolation, completely contained on the graphics processing unit (GPU). This implies that the CPU does not need to compute any lookup tables or B-spline basis functions. The cubic interpolation can be decomposed into several linear interpolations [Sigg and Hadwiger 05], which are hard-wired on the GPU and therefore very fast. Here it is demonstrated tha...

Cardiorenal Syndrome Type 1 (Type 1) is a specific condition which is characterized by a rapid worsening of cardiac function leading to acute kidney injury (AKI). Even though its pathophysiology is complex and not still completely understood, oxidative stress seems to play a pivotal role. In this study, we examined the putative role of oxidative stress in the pathogenesis of CRS Type 1. Twenty-...

Accurate estimation of an underlying function and its derivatives is one of the central problems in statistics. Parametric forms are often proposed based on the expert opinion or prior knowledge of the underlying function. However, these strict parametric assumptions may result in biased estimates when they are not completely accurate. Meanwhile, nonparametric smoothing methods, which do not im...

introduction:  il-8 is one of the pro-inflammatory cytokines which can play an essential role in the pathogenesis of chronic rhinosinusitis (crs) as well as nasal polyposis (np). the ability of individuals in producing il-8 is partially determined by il-8-251 a/t polymorphism. hence, the aim of the present study was to investigate the association between il-8-251 a/t and cxcr2 +1208 c/t genes p...

Crown simulation based on basis spline (b-spline) interpolation is a compatible method to simulate tree polymorphism at present. However, there are two problems when it simulates the crown: first problem that derivative value top point needs be given manually, and second type of collected equidistantly. To solve above realize convenient accurate simulation, this study took Chinese fir as object...

ABSTRACT Cajal-Retzius neurons (CRs) are among the first-born in developing cortex of reptiles, birds and mammals, including humans. The peculiarity CRs lies fact they initially embedded into immature neuronal network before being almost completely eliminated by cell death at end cortical development. best known for controlling migration glutamatergic formation layers through secretion glycopro...

background: community pharmacies are considered as ideal settings to provide cardiovascular risk screening (crs). however, little is known about pharmacists’ views on providing such services in developing countries including iran. in the present study, we evaluated the pharmacists’ attitudes and perceived barriers to providing crs services. methods: in a cross-sectional study, a questionnaire i...

In this work is developed a new four-dimensional algorithm for studying geological features on Mars using high-resolution stereo camera. The 4-D B-spline model has been implemented to reconstruct such as craters. solid simultaneously trace tag craters in sequences of camera slices by completely identifying surfaces which ally themselves with attached pixels. study shows that can identify flow p...
