Convexity of Bẻzier nets on sub-triangles [PDF]
, 1990 This note generalizes a result of Goodman[3], where it is shown that the convexity of Bèzier nets defined on a base triangle is preserved on sub-triangles obtained from a mid-point subdivision process.

Journal of Mathematical Analysis and Applications, 2000 We know that a real-valued function \(f: D\to\mathbb{R}\) defined on a nonempty convex set \(D\) is called convex (on \(D\)) if the inequality \[ f(\lambda x+ (1-\lambda) y)\leq \lambda f(x)+ (1-\lambda) f(y)\quad (x,y\in D,\;\lambda\in (0,1)) \] holds. Here, the author studies the conditional version of the above inequality in the cases when (i) \(y= \

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Advanced Functional Materials, EarlyView.Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Advanced Functional Materials, EarlyView.Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Strict 2-Convexity And Strict Convexity
Demonstratio Mathematica, 1998 The authors first characterize strict convexity of linear 2-normed spaces and then provide necessary and sufficient conditions for a linear 2-normed space to be strictly 2-convex.

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Advanced Healthcare Materials, EarlyView.Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Advanced Healthcare Materials, EarlyView.Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...
