A tangential regularization method for backflow stabilization in hemodynamics [PDF]

, 2013
In computational simulations of fluid flows, instabilities at the Neumann boundaries may appear during backflow regime. It is widely accepted that this is due to the incoming energy at the boundary, coming from the convection term, which cannot be ...

Glazing Effects on Dynamic‐Insulation TSC Façades: A CFD‐Supported Experimental Study of Flow, Heat Transfer, and Ventilation Preheating

Energy Science &Engineering, EarlyView.
Glazed transpired solar collectors achieve 48–75% efficiency and 11% more seasonal heat than unglazed designs by cutting convective losses, while both offer complementary benefits for ventilation preheating and dynamic wall insulation, with paybacks of 5.5–6.8 years.

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Sizing and concentration analysis of cfDNA using Biabooster technology: Results from a prospective plasma‐based collection of 77 patients with locally advanced unresectable esophageal cancer

International Journal of Cancer, EarlyView.
What's New? This study introduces a novel approach for detecting locally advanced esophageal carcinoma using cell‐free DNA (cfDNA) analysis through a highly sensitive fragmentome assay. Unlike traditional sequencing‐based methods that are limited by the absence of specific mutations in esophageal tumors, our method offers an alternative by quantifying ...

Zero energy homes: Combining energy efficiency and solar energy technologies

, 2000
In a typical Florida house, air-conditioning accounts for about 35% of all the electricity the home uses. As the largest single source of energy consumption in Florida, a home's air-conditioning load represents the biggest energy challenge facing Florida

Singularities in the flying electromagnetic doughnuts

Nanophotonics, 2019
Flying doughnuts (FDs) are exact propagating solutions of Maxwell equations in the form of single-cycle, space-time non-separable toroidal pulses. Here we review their properties and reveal the existence of a complex and robust fine topological structure.

Investigation of stresses and deformation forces in energy-intensive pressing processes with backflow of metal

E3S Web of Conferences
Although a large number of studies have been carried out to optimize the processes of pressing metals and alloys, the recommendations for industrial use are ambiguous and cannot be extended to the entire product range. To a special extent, this applies to hollow products such as cups with a flange for the manufacture of which, the most rational and ...

Beyond Bioenergetics: Moonlighting Functions of F1FO‐ATPase From ATP Synthesis to an ATP‐Wasting Death Switch

Medicinal Research Reviews, EarlyView.
ABSTRACT Mitochondrial F1FO‐ATPase is classically viewed as the “splendid” rotary nanomachine that sustains life by converting the proton‐motive force (pmf) into ATP. Yet this same complex can adopt a second, context‐dependent function that links bioenergetics to cell fate.
