Advanced Functional Materials, EarlyView.In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Effect of non-polynomial input to a switching circuit [PDF]
, 2001 In this paper, the validity of the state-space averaging method is analyzed. We assume that the state-space piecewise method is an exact model for a fast switching circuit.

About some exponential inequalities related to the sinc function
Journal of Inequalities and Applications, 2018 In this paper, we prove some exponential inequalities involving the sinc function. We analyze and prove inequalities with constant exponents and inequalities with certain polynomial exponents. Also, we establish intervals in which these inequalities hold.

The Sidon constant for homogeneous polynomials
, 2009 The Sidon constant for the index set of nonzero m-homogeneous polynomials P in n complex variables is the supremum of the ratio between the l^1 norm of the coefficients of P and the supremum norm of P in D^n. We present an estimate which gives the right order of magnitude for this constant, modulo a factor depending exponentially on m.

Algebraic derivations with constants satisfying a polynomial identity
Israel Journal of Mathematics, 2003 The authors continue the line of investigation started by \textit{I. N. Herstein} and \textit{L. Neumann} [Ann. Mat. Pura Appl., IV. Ser. 102, 37-44 (1975; Zbl 0302.16020)]. The philosophy is that if \(R\) is a unitary algebra over a commutative ring \(C\) and \(b\in R\) is integral over \(C\), then the centralizer \(C_R(b)\) is large enough in the ...

Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

An Algorithmic Metatheorem for Directed Treewidth [PDF]
, 2015 The notion of directed treewidth was introduced by Johnson, Robertson, Seymour and Thomas [Journal of Combinatorial Theory, Series B, Vol 82, 2001] as a first step towards an algorithmic metatheory for digraphs.

On the Bernstein Constants of Polynomial Approximation
Constructive Approximation, 2006 Assume \(\alpha >0\) is not an integer. In papers published in 1913 and 1938, S.~N.~Bernstein established the limit $$\Lambda _{\infty ,\alpha }^{\ast }=\lim_{n\rightarrow \infty }n^{\alpha}E_{n}[ \vert x\vert ^{\alpha };L_{\infty }[ {-}1,1]] .$$ Here \(E_{n}[ \vert x\vert ^{\alpha };L_{\infty }[ -1,1] ] \) denotes the error in best uniform ...

Advanced Healthcare Materials, EarlyView.A tunable methacrylated decellularized bone matrix hydrogel (dECM‐MA) is developed to support 3D culture of human osteoblasts. The hydrogel preserves bone‐specific ECM cues and allows precise control over mechanical properties. This system provides a customizable platform for studying osteogenic differentiation and modeling bone tissue environments for
