Constructing artificial assemblies that combine proteins and synthetic ligands has been hampered by the lack of protein-ligand interfaces that are sufficiently large and organized to enable precise structural control. Here ribosome display selection is used to identify a protein that binds a helical aromatic foldamer…
Experimental data on methanol synthesis were obtained in a laboratory flow reactor over an industrial Cu/Zn/Al₂O₃ catalyst (Katalko 51-8) using fractions of 0.5-1 mm, 1-3 mm, and whole pellets (5×5 mm cylinders) at pressures of 31, 41, and 49 bar and temperatures of 200-270 °C. Based on the literature kinetics of Graa…
Abstract The exact exchange--correlation potential $v_{\mathrm{xc}}$ in time-dependent density functional theory (TDDFT) is a causal functional of the full density history, a dependence that widely used adiabatic approximations discard. We ask whether this history dependence can be approximated by a learnable finite-d…
DRAM电容介质在1z nm节点以下面临漏电×EOT缩放的硬约束(IMW 2020),产业30年以掺杂钉扎四方相稳定高k介质(ZrO₂/HfO₂基)为应对——但这一长期实践缺少统一的判据语言。本文用场域理论框架(材料=密度聚类场ρ=m·p;相变候选=失效线R'=1平衡区;剪切软模=相变活性签名)对DRAM高k介质给出可计算判据坐标。核心结果:①软模判据产业命中验证——高k介质家族6材料对照中,唯一具有反铁电(AFE)相变活性的ZrO₂恰好是唯一落软模区(C44=20.3 GPa≤阈值22.7)的Hf/Zr氧化物,其余产业稳定介质全部不软(正1/1负4/4);②二维判据空间——软模轴(相变活性/0K亚稳)×带隙轴(漏电墙),ZrO₂…
Biodiversity monitoring is expanding beyond species counts toward integrated assessment of biological, chemical, physical, and geographic conditions. Microplastics and nanoplastics (MPs/NPs) are now documented across freshwater, marine, terrestrial, sedimentary, and biological systems, yet measurements remain sparse b…
Classical coupled thermoelastic-diffusion theories adequately describe the interaction of thermal, mechanical, and mass-transport fields in homogeneous media, yet they fail to capture microstructural concentration effects that govern the response of layered systems in which a diffusive medium is confined between elast…
water quality through infrastructure damage, sediment resuspension, runoff, and mobilization of plastic debris. Published studies document several-fold to order-of-magnitude changes in environmental microplastic (MP) concentrations during or after these events. Conventional laboratory methods limit the frequency and g…
By mapping the 240 root vectors onto a non-Abelian braiding manifold, we derive a Torsion Field where information is encoded via the topological winding of 132 Hz phase-locked Majorana currents. This discovery establishes that information transfer occurs through the geometric twisting of the E8 lattice itself, where p…
В статье рассматривается возможность использования алгоритма FMEA-анализа как основы для обучения нейронной сети для снижения рисков аварий кислородного конвертера металлургического предприятия. Большинство технологических процессов на металлургическом предприятии связано с высоким уровнем риска. Контроль фактического…
Multi-target drug design has emerged as a promising strategy to overcome the limitations of single-target drugs, particularly in combating infectious diseases that develop resistance through different mechanisms. Enzymes in the Menaquinone (MK) biosynthesis pathway of Staphylococcus aureus represent attractive targets…
This paper proposes a novel framework, termed Dark Matter Structure Transition (DMST), to investigate the nature of dark matter. The core concept revolves around the potential for dark matter structures to undergo phase transitions, characterized by changes in their fundamental properties. Specifically, we posit that…
In the present study, we found that the yield strength of the nickel-based single-crystal superalloys increases with increasing temperatures. However, when the tensile temperature is elevated up to 900 °C, the alloy shows a strain softening behavior without catastrophic shear banding or macroscopic strain localization…
Two multi-sequence generalizations of Beatty's theorem, both derived from a single geometric observation (the Height Lemma) about monotone paths crossing the faces of a cubical tiling of the positive orthant. The first partitions the positive integers into n sieved Beatty sequences; the second keeps the Beatty sequenc…

Abstract Current methods for enzymatic activity assays achieve high sensitivity but require a long assay time, restricting their application in rapid clinical diagnostics. Herein, an ultrarapid and ultrasensitive dual-mode biosensing platform was developed by integrating a high-frequency quartz crystal microbalance (H…
Background/Objectives: Nanoparticle carriers can enhance cancer immunotherapy by improving tumor delivery, activating innate immune responses, and remodeling tumor microenvironments. This review evaluates four categories of formulations: poly(lactic-co-glycolic acid) (PLGA) nanoparticles, mesoporous silica nanoparticl…
The concept of elasticity is central to the understanding of how materials deform and recover under external forces. Classical continuum mechanics describes elasticity through smooth fields of stress and strain that are valid when the material dimensions are much larger than the characteristic interatomic spacing. How…
Abstract Glasses made from organic-inorganic hybrid perovskites are emerging non-crystalline semiconducting materials whose versatile composition and exceptional processability allow for manifold applications. The current melt-quenching approaches are compatible to only few perovskite crystals, as most undergo irrever…
This paper presents a theoretical investigation of transient thermal stress wave propagation in microvoided cylindrical semiconductor metamaterials governed by a bi-fractional heat conduction model. The formulation is developed within the framework of generalized thermoelasticity with voids, where microvoids introduce…
Linde Type A (LTA) zeolite was synthesised from purified Angren kaolin (Uzbekistan) by a metakaolin route. Raw kaolin was beneficiated by dispersion–decantation to reduce iron, calcined at 700 °C, and crystallised in NaOH solution at 100 °C. Products were characterised by powder X-ray diffraction (PXRD), X-ray fluores…
