Structural Guidance in 3D Microgel‐in‐Hydrogel Systems to Improve Chondrogenesis
The Anisogel, an anisotropic microgel‐in‐hydrogel system, guides chondrogenic differentiation of human mesenchymal stromal cells (hMSCs) modulated by the alignment and size of anisometric microgels. Chondrogenic markers are upregulated in an in vitro model and guided tissue infiltration is enhanced in a semi‐orthopedic mouse model due to the physico ...

On Best Multiplier Approximation of k-Monotone by Trigonometric Polynomial
The main goal of this paper is to study the degree of the best multiplier approximation of monotone unbounded functions in L_(p,λ_n)-space on the closed interval [-π,π] by means of K-functional, which we represented with, K(f,L_(p,λ_n ),W_(p,λ_n)^1,W ̃_(

This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

On the equivalence of the modulus of smoothness and the K-functional over convex domains
It is well known that for any bounded Lipschitz graph domain \(\Omega\subset\mathbb R^d,r\geq 1\) and \(1\leq p\leq \infty\) there exist constants \(C_1(d,r), C_2(\Omega,d,r,p)>0\) such that for any function \(f\in L_p(\Omega)\) for \(t>0\) \[ C_1(d,r)\omega_r(f,t)_p\leq K_r(f,t^r)_p\leq C_2(\Omega,d,r,p)\omega_r(f,t)_p, \] where \(\omega_r(f,t)_p\) is

A note on an inverse theorem for a generalised modulus of smoothness
We prove the theorem converse to Jackson's theorem for a modulus of smoothness of the first order generalised by means of an asymmetric operator of generalised translation.

On moduli of smoothness of fractional order [PDF]
In this paper we consider the properties of moduli of smoothness of fractional order. The main result of the paper describes the equivalence of the modulus of smoothness and a function from some ...
