Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Algebraic Point Projection for Immersed Boundary Analysis on Low Degree NURBS Curves and Surfaces
Point projection is an important geometric need when boundaries described by parametric curves and surfaces are immersed in domains. In problems where an immersed parametric boundary evolves with time as in solidification or fracture analysis, the ...

Degrees of Parametrizations of Elliptic Curves by Shimura Curves
Let \(N\) be a square-free positive integer and \((D,M)\) a pair of positive integers such that \(N=DM\) and the number of prime factors of \(D\) is even. Consider the Shimura curve \(X_0^D(M)\) associated with an Eichler order of level \(M\) in an indefinite quaternion algebra of discriminant \(D\) defined over the field of rational numbers \(\mathbb ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Constant-Ratio Blended Models of Curves and Surfaces in Euclidean 3-Space
We consider a simple blending method for parametric curves and surfaces. The described blending method offers a systematic approach to creating smooth transitions between parametric curves and surfaces while maintaining Cn-continuity.

This paper concerns modelling of surfaces resulting from measurements or from digital simulation of surfaces e.g., tooth flanks, based on the theory of gearing, with intentionally introduced modification usually defined in discrete form.

Certain Algorithms for Modeling Uncertain Data Using Fuzzy Tensor Product Bézier Surfaces
Real data and measures are usually uncertain and cannot be satisfactorily described by accurate real numbers. The imprecision and vagueness should be modeled and represented in data using the concept of fuzzy numbers.

Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

PARAMETRIC ROSE AS A SUBJECT OF MATHEMATICS, PROGRAMMING, AESTHETICS.
By using MATLAB we demonstrate a variety of parametric curves of the family "Parametric Rose" (Rhodonea), characterized by four factors. The article is intended to encourage students to study the parametric curves.

Dual-optimization trajectory planning based on parametric curves for a robot manipulator
This article presents a dual-optimization trajectory planning algorithm, which consists of the optimal path planning and the optimal motion profile planning for robot manipulators, where the path planning is based on parametric curves.
