Rank-preserving geometric means of positive semi-definite matrices

, 2012
The generalization of the geometric mean of positive scalars to positive definite matrices has attracted considerable attention since the seminal work of Ando.

Neural Network Adaptive Control With Long Short‐Term Memory

International Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT In this study, we propose a novel adaptive control architecture that provides dramatically better transient response performance compared to conventional adaptive control methods. This is accomplished by the synergistic employment of a traditional adaptive neural network (ANN) controller and a long short‐term memory (LSTM) network.

Matrix multinomial distribution [PDF]

arXiv, 2021
In this article, we define a matrix multinomial distribution. We prove some properties of the matrix multinomial distribution. We prove that the matrix Poisson distribution can be used as an approximation to the matrix multinomial distribution under certain conditions.

Salt‐Compact Albumin as a New Pure Protein‐based Biomaterials: From Design to In Vivo Studies

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A new class of materials built entirely of native albumin protein is designed using a simple protocol based on salt‐assisted compaction, breaking with current crosslinking strategies. This green process leads, surprisingly, to water‐insoluble handable materials with high preservation of their native protein structures and Young's modulus close to that ...

A study on Horn matrix functions and its confluent cases [PDF]

arXiv, 2022
In this paper, we give the matrix version of Horn's hypergeometric function and its confluent cases. We also discuss the regions of convergence, the system of matrix differential equations of bilateral type, differential formulae and infinite summation formulae satisfied by these hypergeometric matrix functions.

HARMLESS Early Warning System for Advanced Materials

Advanced Sustainable Systems, EarlyView.
The HARMLESS Early Warning System tackles Advanced Materials (AdMa) risk governance by providing a framework, organised in two tiers, underpinned with methods/tools to support risk assessors in the pre‐assessment preceding risk assessment. It allows for initial screening to identify AdMa with concerns considering exposure, hazards, sustainability and ...

On the incomplete Lauricella matrix functions of several variables [PDF]

arXiv, 2020
In this article, we introduce incomplete Lauricella matrix functions (ILMFs) of $n$ variables through application of the incomplete Pochhammer matrix symbols. Furthermore there is derivation of certain properties; matrix differential equation, integral formula, recursion formula and differentiation formula of the ILMFs. We also establish the connection

Positive definite solutions of certain nonlinear matrix equations

, 2016
We investigate positive definite solutions of nonlinear matrix equations X− f (Φ(X))= Q and X −∑i=1 f (Φi(X)) = Q , where Q is a positive definite matrix, Φ and Φi (1 i m) are positive linear maps on Mn(C) and f is a nonnegative matrix monotone or matrix

On The Positive Definiteness of Polarity Coincidence Correlation Coefficient Matrix [PDF]

IEEE Signal Processing Letters, 2008
Polarity coincidence correlator (PCC), when used to estimate the covariance matrix on an element-by-element basis, may not yield a positive semi-definite (PSD) estimate. Devlin et al. [1], claimed that element-wise PCC is not guaranteed to be PSD in dimensions p>3 for real signals. However, no justification or proof was available on this issue.

Accelerated Bone Healing via Electrical Stimulation

Advanced Science, EarlyView.
Electrical stimulation significantly impacts bone healing by enhancing osteoblast proliferation, differentiation, and vascularization through calmodulin/calcineurin/NFAT signaling. It also boosts macrophage function and cell migration, presenting a comprehensive approach to accelerating bone repair.
