Lagrangian-Eulerian approximation methods for balance laws and hyperbolic conservation laws

Revista UIS Ingenierías, 2018
A new finite control volume in a Lagrangian-Eulerian framework is presented (see papers [1, 28]), in which a local space-time domain is studied, in order to design a locally conservative scheme.

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Nanodiamond Regulated Electrolyte Enhances Thermal, Chemical and Structural Properties for Highly Reversible Zn Metal Anodes

Advanced Science, EarlyView.
Nanodiamond additives are dispersed in the aqueous electrolyte to organize water molecules, suppress gas evolution and metal corrosion, and guide zinc to deposit more uniformly. Together with enhanced thermal conductivity for fast heat removal, this strategy reduces temperature rise and degradation, enabling safer, more durable rechargeable zinc metal ...

Symmetry Reductions of the (1 + 1)-Dimensional Broer–Kaup System Using the Generalized Double Reduction Method

Axioms
The generalized theory of the double reduction of systems of partial differential equations (PDEs) based on the association of conservation laws with Lie–Bäcklund symmetries is one of the most effective algorithms for performing symmetry reductions of ...

Calcium Channel Blockers Inhibit Pancreatic Neuroendocrine Neoplasms Progression via Cav1.2‐Epigenetic Circuit

Advanced Science, EarlyView.
Our study reveals a novel mechanism of a positive regulatory circuit between Cav1.2 and H3K27ac for pancreatic neuroendocrine neoplasms (pNENs) progression. Cav1.2 is identified as a crucial target for promoting disease progression and correlates with malignant behaviors, which are remarkably inhibited by the administration of calcium channel blockers (

Infinitesimal symmetries and conservation laws of the DNLSE hierarchy and the Noether's theorem

, 2006
The hierarchy of the integrable nonlinear equations associated with the quadratic bundle is considered. The expressions for the solution of the linearization of these equations and their conservation law in the terms of the solutions of the corresponding

Quantitative Stain Mapping in X‐Ray Virtual Histology

Advanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Neural Network‐Based Permittivity Engineering of Magnetic Absorbers for Customizable Microwave Absorption

Advanced Science, EarlyView.
A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...

Wildlife lost in translation: Understanding low compliance with outdated wildlife hunting legislation in Sierra Leone

Conservation Science and Practice
In Sierra Leone, antiquated wildlife conservation laws from the 1970s have failed to curb unsustainable hunting and trading of bushmeat. Our research examined why compliance remains low five decades after adoption. It explores hunter and trader awareness
