Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Existence of Unique Limiting Probability Vectors in Stochastic Processes with Multiple Transition Matrices

open access: yesJournal of Agricultural and Resource Economics, 1992
Concepts associated with stochastic process containing multiple transition matrices are discussed. It is proved that under certain conditions, a process with m transition matrices has m unique limiting probability vectors.

On matrices with a doubly stochastic pattern

open access: yesJournal of Mathematical Analysis and Applications, 1971
In [7] Sinkhorn proved that if A is a positive square matrix, then there exist two diagonal matrices D, = {@r,..., d$) and D, = {dj2),..., di2r) with positive entries such that D,AD, is doubly stochastic. This problem was studied also by Marcus and Newman [3], Maxfield and Mint [4] and Menon [5]. Later Sinkhorn and Knopp [8] considered the same problem

Doubly stochastic circulant matrices

open access: yesDiscrete Mathematics, 1991
Let \(P_ n\) be the circulant matrix of order \(n\) with the first row of the form \((0,1,0,\ldots,0)\). Let \(G^ 2_ n\) denote the set of all \(n\times n\) doubly stochastic matrices of the form \(\alpha_ nI_ n+\beta P_ n+\gamma_ nP_ n^ 2\), and let \(\mu_ n\) denote the minimum value of the permanent on \(G^ 2_ n\). In the note the lower bound for \(\

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Stochastic bra-ket interpretation of quantum mechanics

open access: yesJournal of Physics Communications
The stochastic nature of quantum mechanics is more naturally reflected in a bilinear two-process representation of density matrices rather than in squared wave functions.

Neuromorphic Electronics for Intelligence Everywhere: Emerging Devices, Flexible Platforms, and Scalable System Architectures

open access: yesAdvanced Materials, EarlyView.
The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...
