We describe an approximating scheme based on cubic C1 splines type-6 tetrahedral partitions using data volumetric grids. The quasi-interpolating piecewise polynomials are directly determined by setting their Bernstein-Bezier coefficients to appropriate combinations of the values. Hence, each polynomial piece spline is immediately available from local portions data, without prescribed derivatives at any point domain. locality method and uniform boundedness associated operator provide error...

We show that for many spaces of bivariate splines imposing certain additional individual smoothness conditions on a spline space does not change the space. Such possess supersmoothness is reflected in their standard definitions. Smoothness treated as vanishing strongly supported functionals. investigate dependence this phenomenon geometry underlying partition and degree splines.
Pathogenic CFTR variants cause cystic fibrosis (CF), and CF-related disorders (CF-RD), including bilateral aplasia of the vas deferens (CBAVD). The spectrum clinical manifestations depends on genotype. frequency vary between populations groups. genotypes were analyzed in Russian men with CF (n = 546) CBAVD syndrome 125). detected 93.95% 39.2% alleles, respectively. most frequent c.1521_1523del (F508del; p.Phe508del) variant was found 541 (49.5%) alleles. A total 162 revealed patients, 152...
(1) Introduction: Pathogenic variants in the CFTR (Cystic Fibrosis Transmembrane conductance Regulator, OMIM: 602421) gene cause Cystic (CF, 219700) and CF-related disorders (CF-RD), often accompanied by obstructive azoospermia due to congenital bilateral aplasia of vas deferens (CBAVD, 277180) male patients. The L138ins (c.413_415dup; p. (Leu138dup)) is a mild variant that relatively common among CF-patients Slavic populations. frequency this Russian infertile men has not been sufficiently...
Dimensions of spaces multivariate splines remain unknown in general. A computational method to obtain explicit formulas for the dimension spline on simplicial partitions is described. The based Hilbert series and polynomials. It applied conjecture Alfeld split a simplex several other partitions.
The main purpose of the present research is to define impact changes that took place in monetary and credit policy Russian Federation. touched upon regulatory issues mortgage lending which have influenced some aspects life population, including affordability factor square meter housing prices article analyzes money incomes population RF, source average salary, rates, volume number credits granted period from 2019 third quarter 2021. This reflects current situation takes into account economic...
Instead of using the full polynomial space, a conforming and nonconforming finite element methods are designed where only harmonic polynomials (a much smaller space) employed in computation. The quadratic is defined on special triangular grid. general grids. optimal order convergence proved for both methods, confirmed by numerical computations. In addition, comparisons with standard elements presented.
We consider spaces of multivariate splines defined on a particular type simplicial partitions that we call (generalized) oranges. Such are composed finite number maximal faces with exactly one shared medial face. reduce the problem finding dimension oranges to computing dimensions simpler, lower-dimensional projected use both algebraic and Bernstein-Bézier tools.
Globozoospermia is a form of male infertility characterized by spermatozoa with spherical heads lacking acrosomes. The aim this study was to evaluate ultrastructural and molecular defects in different types globozoospermia. Semen samples from 12 infertile patients (9 complete globozoospermia 3 partial globozoospermia) 10 normozoospermic men (control) were examined transmission electron microscopy immunocytochemistry antibodies against lamin B1. presence A progerin assessed reverse...
(1) Background: The androgen receptor (AR) is critical for mediating the effects of androgens. polymorphic CAGn locus in exon 1 AR gene associated with several diseases, including spinal and bulbar muscular atrophy (SBMA), prostate cancer, male infertility. This study evaluated 9,000 infertile Russian men 286 fertile (control group); (2) Methods: was analyzed using polymorphism lengths amplified fragments method; (3) Results: In cohort, CAG repeats ranged from 6 to 46, a unimodal...
