Cauchy-characteristic Evolution of Einstein-Klein-Gordon Systems: The Black Hole Regime
, 1996 The Cauchy+characteristic matching (CCM) problem for the scalar wave equation is investigated in the background geometry of a Schwarzschild black hole. Previously reported work developed the CCM framework for the coupled Einstein-Klein-Gordon system of ...

Exceptional aggressiveness of cerebral cavernous malformation disease associated with PDCD10 mutations. [PDF]
, 2015 PurposeThe phenotypic manifestations of cerebral cavernous malformation disease caused by rare PDCD10 mutations have not been systematically examined, and a mechanistic link to Rho kinase-mediated hyperpermeability, a potential therapeutic target, has ...

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Advanced Functional Materials, EarlyView.Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

A Quantitative Comparison of SMC, LMC, and Milky Way UV to NIR Extinction Curves
, 2003 We present an exhaustive, quantitative comparison of all of the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general behavior of Milky Way extinction curves.

Advanced Functional Materials, EarlyView.Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Ground-state phases of the spin-1 $J_{1}$--$J_{2}$ Heisenberg antiferromagnet on the honeycomb lattice [PDF]
, 2016 We study the zero-temperature quantum phase diagram of a spin-1 Heisenberg antiferromagnet on the honeycomb lattice with both nearest-neighbor exchange coupling $J_{1}>0$ and frustrating next-nearest-neighbor coupling $J_{2} \equiv \kappa J_{1} > 0 ...

Advanced Functional Materials, EarlyView.This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with
