Advanced Science, EarlyView.A mechanically robust, self‐healable, moisturizing, cryotolerant and adhesive GelMA hydrogel is developed by incorporating polyvinyl alcohol, acrylic acid, sodium tetraborate, and glycerol into GelMA matrix via a photoinitiated polymerization process. The hydrogel‐derived omni‐healable ionotronic pressure sensor can sensitively and consistently monitor

On p.p.-rings which are reduced
International Journal of Mathematics and Mathematical Sciences, 2006 Denote the 2×2 upper triangular matrix rings over ℤ and ℤp by UTM2(ℤ) and UTM2(ℤp), respectively. We prove that if a ring R is a p.p.-ring, then R is reduced if and only if R does not contain any subrings isomorphic to UTM2(ℤ) or UTM2(ℤp).

Advanced Science, EarlyView.In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

Linear Maps on Upper Triangular Matrices Spaces Preserving Idempotent Tensor Products
Abstract and Applied Analysis, 2014 Suppose m, n≥2 are positive integers. Let 𝒯n be the space of all n×n complex upper triangular matrices, and let ϕ be an injective linear map on 𝒯m⊗𝒯n. Then ϕ(A⊗B) is an idempotent matrix in 𝒯m⊗𝒯n whenever A⊗B is an idempotent matrix in 𝒯m⊗𝒯n if and only ...

Advanced Science, EarlyView.Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Fine spectrum of the upper triangular matrix U(r, 0, 0, s) over the sequence spaces c₀ and c
, 2018 Fine spectra of various matrices have been examined by several authors. In this article we have determined the fine spectrum of the upper triangular matrix U(r, 0, 0, s) on the sequence spaces c₀ and ...

On the graded automorphisms of upper triangular matrix algebras
, 2017 We compute the graded automorphisms of the upper triangular matrices, viewed as associative, Lie and Jordan algebras. We compute also the so called self-equivalences and Weyl and diagonal groups for every grading.

qcGEM: A Graph‐Based Molecular Representation With Quantum Chemistry Awareness
Advanced Science, EarlyView.In this work, we introduce qcGEM, a quantum‐chemistry‐aware graph‐based embedding of molecules that incorporates physical priors into molecular representation learning. Through a specially designed model architecture to adequately process quantum chemistry information as well as three‐dimensional molecular geometry, qcGEM provides a compact, physics ...
