Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

[Non-traumatic perforation of the small intestine].
Acta chirurgica Iugoslavica, 1979 From, 1971-1979, 14 patients with non-traumatic perforations of the small intestine were treated in the Department of General and Abdominal Surgery of the Universitäts-klinik Frankfurt/Main. In 8 cases suture and by-pass, and/or interval operation with enterostomy was performed. Seven patients survived, one patient died.

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil
Deep Underground Science and Engineering, EarlyView.Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Deep Underground Science and Engineering, EarlyView.The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

Sacrificing Energy for Mass Transfer to Boost Solar Steam Generation
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Vapor accumulation often limits the performance of passive interfacial solar evaporation. Inspired by the Dyson sphere concept, Xu, Yang, and co‐workers designed a perforated‐shell evaporator with an internal non‐evaporating core that diverts incident sunlight to drive self‐generated internal convection for vapor removal.

Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications
Exploration, EarlyView.There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive

Food Chemistry International, EarlyView.Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.
