Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Automorphisms and derivations of upper triangular matrix rings
Linear Algebra and its Applications, 1995 The paper deals with automorphisms and derivations of \(T_n(A)\), the algebra of upper triangular matrices over an algebra \(A\), as well as of some other algebras. A sample result: Let \(A\) be either a semiprime ring or a ring whose idempotents are all central. Let \(C\) be a central subring of \(A\).

Advanced Science, EarlyView.Deep‐learning‐based signal enhancement is an effective way to recover high‐resolution details from a low‐resolution chromatin contact map. However, due to computational challenges, existing methods commonly divide up the contact map into small patches and create artificial discontinuities at patch boundaries.

Decomposition of Lie automorphisms of upper triangular matrix algebra over commutative rings
Linear Algebra and its Applications, 2006 Let 2 be an invertible element in the commutative ring \(R\) and let \(T_{n+1}(R)\) be the algebra of \((n+1)\times (n+1)\) upper triangular matrices with entries in \(R\). In the paper under review the authors describe the Lie automorphisms of \(T_{n+1}(R)\), i.e. the \(R\)-module automorphisms \(\varphi\) of \(T_{n+1}(R)\) with the property \(\varphi(

Advanced Science, EarlyView.Short‐range order in 2D transition metal dichalcogenides is revealed as a new design paradigm. Driven by chemical affinity and atomic size, it governs properties across scales. Weak ordering tunes site‐resolved magnetism and d‐band centers, while strong ordering eliminates gap states to open band gaps.

Jordan left derivations in infinite matrix rings
Demonstratio MathematicaLet RR be a unital associative ring. Our motivation is to prove that left derivations in column finite matrix rings over RR are equal to zero and demonstrate that a left derivation d:T→Td:{\mathcal{T}}\to {\mathcal{T}} in the infinite upper triangular ...

Advanced Science, EarlyView.ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

Idempotent McCoy Rings and Their Properties
Journal of MathematicsThis paper introduces idempotent McCoy rings, extending McCoy rings by incorporating idempotent elements, and explores their key properties. We provide examples and a counterexample showing that not every idempotent McCoy ring is McCoy.

Advanced Science, EarlyView.Using single‐cell transcriptomic and epigenomic profiling, researchers mapped microglial dysfunction across the lifespan of db/db mice. The authors uncovered a nonlinear microglial remodeling featuring early inflammatory priming, a mid‐stage transcriptional inflection, and late dysfunction.
