Positive-Definite Tensors to Nonlinear Complementarity Problems [PDF]
, 2015 The main purpose of this paper was to investigate some kinds of nonlinear complementarity problems (NCP). For the structured tensors, such as symmetric positive-definite tensors and copositive tensors, we derive the existence theorems on a solution of ...

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress
Advanced Materials Technologies, EarlyView.Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

On Third Order Stable Difference Scheme for Hyperbolic Multipoint Nonlocal Boundary Value Problem
Discrete Dynamics in Nature and Society, 2015 This paper presents a third order of accuracy stable difference scheme for the approximate solution of multipoint nonlocal boundary value problem of the hyperbolic type in a Hilbert space with self-adjoint positive definite operator.

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Advanced Science, EarlyView.The cysteine redox state of the Hendra virus W (WHeV) protein controls assembly into fibrils or amorphous aggregates, with residues 2–29 required for fibrillation. In cells, WHeV forms different types of nuclear condensates. Impaired ability to form redox‐sensitive, non‐filamentous condensates reduces WHeV inhibition of the NF‐κB pathway, while it ...

Solvability Theory and Iteration Method for One Self-Adjoint Polynomial Matrix Equation
Journal of Applied Mathematics, 2014 The solvability theory of an important self-adjoint polynomial matrix equation is presented, including the boundary of its Hermitian positive definite (HPD) solution and some sufficient conditions under which the (unique or maximal) HPD solution exists ...

Computing the Karcher mean of symmetric positive definite matrices [PDF]
, 2013 We present and analyze an iterative method for approximating the Karcher mean of a set of $n\times n$ positive definite matrices $A_i$, $i=1,\ldots,k$, defined as the unique positive definite solution of the matrix equation $\sum_{i=1}^k \log(A_i^{-1}X)

Advanced Science, EarlyView.An electrochemical platform based on differential pulse amperometry enables real‐time, selective tracking of safinamide pharmacokinetics in the living brain with high spatiotemporal resolution. When integrated with electrophysiology, this approach reveals that drug‐induced suppression of vision‐related neuronal activity provides mechanistic insight ...
