Ultra‐Wideline 2D Correlations Among Low‐γ Species in Solid‐State NMR via the Progressive Saturation of a Common Proton Reservoir

Chemistry – A European Journal, EarlyView.
This study introduces PROSPECT, a 2D solid‐state NMR method that correlates MHz‐wide, low‐γ anisotropic powder patterns. PROSPECT operates by progressively depleting a shared 1H dipolar‐order reservoir via two independently stepped cross‐polarizing offsets, yielding homonuclear and heteronuclear correlations without requiring direct transfers or even ...

N─H or O─H Bond Activation With a Bicyclic Si4 Ring Compound

Chemistry – A European Journal, EarlyView.
The bicyclic Si4 ring compound with zwitterionic character reacts with NH3, H2O, and selected alcohols to give functionalized saturated silicon rings, siliconoid clusters with unsubstituted Si atoms, or simple 1,3‐addition products. The experimentally observed reactivity could be rationalized based on results from mechanistic calculations employing ...

Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

PharmVar GeneFocus: CYP1A2—Clinical Impact, Genetic Variation, and Updated Nomenclature

Clinical Pharmacology &Therapeutics, EarlyView.
The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human CYP1A2 gene. CYP1A2 plays a crucial role in the biotransformation of several commonly used drugs, including antipsychotics, antidepressants, anxiolytics, and methylxanthines.

Stopping Power of Electron Liquid for Slow Quantum Projectiles

Contributions to Plasma Physics, EarlyView.
ABSTRACT We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the classical Ehrenfest dynamics.
