Finite subdivision rules [PDF]
Conformal Geometry and Dynamics of the American Mathematical Society, 2001 We introduce and study finite subdivision rules. A finite subdivision rule R \mathcal {R} consists of a finite 2-dimensional CW complex S R S_{\mathcal {R}} , a subdivision R ( S

Quantum (q, h)-Bézier surfaces based on bivariate (q, h)-blossoming
Demonstratio Mathematica, 2019 We introduce the (q, h)-blossom of bivariate polynomials, and we define the bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces on rectangular domains using the tensor product.

Analyzing midpoint subdivision [PDF]
Computer Aided Geometric Design, 2011 Midpoint subdivision generalizes the Lane-Riesenfeld algorithm for uniform tensor product splines and can also be applied to non regular meshes. For example, midpoint subdivision of degree 2 is a specific Doo-Sabin algorithm and midpoint subdivision of degree 3 is a specific Catmull-Clark algorithm.

GEOMETRIC REDESIGN OF THE SUBDIVIDED SURFACE OF CC II: APPLICATION IN ARCHITECTURE
Journal of Industrial Design and Engineering Graphics, 2019 The concave polyhedral surface of CC II can be used as a structural template for architectural design of domes, roofs or other covering or stand-alone structures.

Multiresolution Subdivision Snakes [PDF]
IEEE Transactions on Image Processing, 2017 We present a new family of snakes that satisfy the property of multiresolution by exploiting subdivision schemes. We show in a generic way how to construct such snakes based on an admissible subdivision mask. We derive the necessary energy formulations and provide the formulas for their efficient computation.

Contemporary Clinical Dentistry, 2019 Treatment of Class II subdivision malocclusion is challenging, and orthodontists frequently struggle to determine the choice of treatment. Several treatment modalities have been proposed for correcting these types of malocclusion.

Subdivision surface simplification [PDF]
10th Pacific Conference on Computer Graphics and Applications, 2002. Proceedings., 2003 A modified quadric error metric (QEM) for simplification of Loop subdivision surfaces is presented The suggested error metric not only measures the geometric difference but also controls the smoothness and well-shapedness of the triangles that result from the decimation process.

Multiple-Function Systems Based on Regular Subdivision
Fractal and Fractional, 2022 Self-similar fractals can be generated using subdivision and the subdivision curves/surfaces are actually attractors. Such a connection has been studied between fractals and an extended family of subdivision including stationary and non-stationary ...

Accuracy and safety of tablet subdivision
Medycyna Ogólna i Nauki o Zdrowiu, 2020 Introduction Tablet subdivision is a common practice among patients and doctors. Tablets can be divided into smaller parts to obtain the desired dose and adjust this dose to the actual needs of the patient.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer
Molecular Oncology, EarlyView.PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...
