Visible‐Light‐Mediated Lewis Acid‐Catalyzed Diradical Hydrogen Atom Transfer Reaction of Enamides

Advanced Science, EarlyView.
The Lewis acid catalysis was crucial for the success of the DHAT reaction of enamides by lowering the energy of the triplet excited state and modulating the reactivity of the formed diradical intermediate in a carbon‐to‐carbon 1,5‐DHAT and consequent cyclization that allows the functionalization of C(sp3)−H bonds to construct a variety of novel β ...

Impact of Hospital Teaching Status on Atrial Fibrillation Ablation Procedural Approaches and Complications: Insights From the National Cardiovascular Data Registry

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Institutional characteristics can affect atrial fibrillation (AF) catheter ablation procedural outcomes. Although hospital teaching status may affect patient care in other settings, its effect on AF ablation is unknown.

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Diverging Liquid–Liquid Phase Separation Behavior of Different Recombinant Major Ampullate Spidroins

Advanced Science, EarlyView.
Fibers spun from the MaSp1‐derivative as well as MaSp1‐MaSp2‐mixtures provide a deeper insight into the assembly process of the spidroins and how hierarchical architectures of spider silk fibers could be achieved. ABSTRACT Spider silk fibers show exceptional mechanical properties, based on their underlying spider silk proteins (spidroins) as well as a ...

El papel de la imaginación en la refutación de Adam Smith a la tesis del homo economicus

Ideas y Valores, 2015
La filosofía moral de Adam Smith se fundamenta en el papel de la imaginación para explicar el orden social en un nivel macro, y como mecanismo de identificación afectiva en un nivel micro.

Development and internal validation of an age less-dependent frailty score in the cardiovascular health study

Frontiers in Medicine
BackgroundFrailty is a proxy for biologic aging that confers risk independently of chronologic age. Most frailty indices correlate strongly with chronologic age, making independent features of biologic aging challenging to identify.MethodsWe aimed to ...

Repurposing FDA‐Approved Drugs to Inhibit Fungal PPTases for Broad‐Spectrum Synergy

Advanced Science, EarlyView.
Fungal secondary metabolites serve as crucial virulence effectors; however, the potential of their biosynthetic pathways as antifungal targets remains inadequately comprehended. Repurposed FDA‐approved drugs inhibit fungal PPTase (essential for secondary metabolism) in vivo.
