Shape-preserving properties of a new family of generalized Bernstein operators
Journal of Inequalities and Applications, 2018 In this paper, we introduce a new family of generalized Bernstein operators based on q integers, called (α,q) $(\alpha,q)$-Bernstein operators, denoted by Tn,q,α(f) $T_{n,q,\alpha}(f)$. We investigate a Kovovkin-type approximation theorem, and obtain the

A generalization of irreducible monotonicity
Linear Algebra and its Applications, 1972 AbstractLet K1 and K2 be pointed closed convex cones with nonempty interiors in Rn and Rm, respectively. Define A ϵ M(K1, K2) if and only if A x ϵ K2, 0 ≠ x ϵ K1, is consistent and A x ϵ K2, 0 ≠ x ϵ K1 ⇒ x ϵ intK1. If K1 and K2 are the nonnegative orthants in their respective spaces, the class M(K1, K2) reduces to the class M of irreducible matrices ...

Evolution‐Driven Bio‐Composite Aerogels for Self‐Adaptive Thermal Regulation and Energy Storage
Advanced Materials, EarlyView.Inspired by nature's multiphase integration, a single chitosan (CTS)–metal chloride (MCl3) coordination precursor is engineered to enable sequential material and functional evolution. The resulting metal ion‐coordinated chitosan (CTS–M) aerogels exhibit humidity‐adaptive thermal insulation for battery safety, while carbonization yields conductive ...

Advanced Materials, EarlyView.We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

Generalized Monotonic Regression Based on B-Splines with an Application to Air Pollution Data [PDF]
, 2005 In many studies where it is known that one or more of the certain covariates have monotonic effect on the response variable, common fitting methods for generalized additive models (GAM) may be affected by a sparse design and often generate implausible ...

Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2
Advanced Materials, EarlyView.A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...

Generalized monotonicity and strategy-proofness: A note [PDF]
In this note we define generalized monotonicity which is a generalized version of monotonicity due to Muller and Satterthwaite (1979) for a social choice function under individual preferences which permit indifference, and shall show that generalized ...

On the monotonicity of generalized barycentric coordinates on convex polygons [PDF]
, 2016 We show that four well-known kinds of generalized barycentric coordinates in convex polygons share a simple monotonicity property: the coordinate function associated with a vertex is increasing along any line from the polygon boundary to that vertex ...

Electrically Coded Retinomorphic Spectrophotodetector
Advanced Materials, EarlyView.Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.
