Finding splitting elements and maximal tori in matrix algebras

, 1999
Roughly speaking, a splitting element of a matrix algebra is an element with a maximal number of eigenvalues. Using randomization, splitting elements can be found very easily and have proved to be extremely useful in computational representation theory ...

Poisson's Ratio‐Driven Control of Myogenic Differentiation and Maturation in Auxetic Metamaterials under Dynamic Mechanical Stimulation

Advanced Functional Materials, EarlyView.
This study explored how innovative “auxetic” scaffolds, which expand when stretched, influence skeletal muscle development. Researchers cultured muscle cells on different scaffold designs and applied repeated stretching over 10 days. They found that scaffold geometry affected muscle cell differentiation and fiber formation.

Highly Efficient and Stable Roll‐to‐Roll Coated Perovskite Solar Cells Enabled by Antisolvent Vapor‐Assisted Crystallization

Advanced Functional Materials, EarlyView.
Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...

Determination of structure coefficients from splitting matrices

, 2016
The splitting matrix for a set of coupled multiplets is a linear combination of structure coefficients, first-order Coriolis terms and terms for ellipticity and centrifugal force.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Minimizing Computation and Communication Costs of Two-Sided Secure Distributed Matrix Multiplication under Arbitrary Collusion Pattern

Entropy
This paper studies the problem of minimizing the total cost, including computation cost and communication cost, in the system of two-sided secure distributed matrix multiplication (SDMM) under an arbitrary collusion pattern. In order to perform SDMM, the

Hermitian and skew-Hermitian splitting methods for non-Hermitian positive definite linear systems

, 2003
We study efficient iterative methods for the large sparse non-Hermitian positive definite system of linear equations based on the Hermitian and skew-Hermitian splitting of the coefficient matrix. These methods include a Hermitian/skew-Hermitian splitting

Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

Advanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
