Atomic‐Scale Insights into Yttrium‐Induced Grain Boundary Structure Modification in Al2O3
Advanced Science, EarlyView.Using advanced STEM characterization combined with NNP‐based MCMD calculations, it is revealed that Y segregation at ∑13 Al2O3 GB involves not only simple substitution of Y for Al atoms but also structural adaptation with a change in GB atomic density, leading to minimized excess volume and lowest GB energy.

Ludwig Hilberseimer and Metropolisarchitecture: The Analogue, the Blasé Attitude, the Multitude
Arts, 2018 This article close-reads Modernist architect Ludwig Hilberseimer’s early architectural projects, which employed a language of uniform fenestration, repetition and geometrically reduced typical forms, as embodying Georg Simmel’s blasé ...

Measuring the Decorrelation Times of Fourier Modes in Simulations
, 1993 We describe a method to study the rate at which modes decorrelate in numerical simulations. We study the XY model updated with the Metropolis and Wolff dynamics respectively and compute the rate at which each eigenvector of the dynamics decorrelates. Our

Advanced Science, EarlyView.ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...

Advanced Science, EarlyView.Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Driven Diffusive Systems: How Steady States Depend on Dynamics
, 2004 In contrast to equilibrium systems, non-equilibrium steady states depend explicitly on the underlying dynamics. Using Monte Carlo simulations with Metropolis, Glauber and heat bath rates, we illustrate this expectation for an Ising lattice gas, driven ...

Advanced Science, EarlyView.This study identifies a conserved CsdA‐LaeB hub in Aspergillus fumigatus that regulates secondary metabolite fumiquinazoline C (FqC). Disrupting this hub enhances FqC production and virulence, shedding new light on the post‐transcriptional regulatory logic linking secondary metabolism to pathogenicity and offering alternative strategies for diagnostic ...
