Multidimensional upwind methods for hyperbolic conservation laws [PDF]

Journal of Computational Physics, 1990
A class of conservative difference algorithms for hyperbolic conservation laws in several space variables which do not make use of operator splitting are presented. These methods are upwind and multidimensional, in that the numerical fluxes are obtained by solving the characteristic form of the full multidimensional equations at the zone edge and that ...

Stability in tapia woodlands amid non‐native expansion: Integrating traditional ecological knowledge and remote sensing to track 73 years of tree cover in Madagascar

People and Nature, EarlyView.
Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

On Lie Symmetries of Hyperbolic Model Metric of SL(n, R) Geometry

پژوهش‌های ریاضی, 2020
Introduction ‎  Symmetries of an equation are closely related to conservation‎ laws‎. ‎Noether's theorem provides a method for finding conservation laws of differential‎ equations arising from a known Lagrangian and having a known Lie symmetry‎.

A hyperbolic conservation law and particle systems [PDF]

Journal of Difference Equations and Applications, 2011
In these notes we consider two particle systems: the totally asymmetric simple exclusion process and the totally asymmetric zero-range process. We introduce the notion of hydrodynamic limit and describe the partial differential equation that governs the evolution of the conserved quantity – the density of particles .

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

Reducing Trade‐Offs of Net Zero Carbon Transitions Through Entrepreneurship and Coordinated Innovation: A Spatially Disaggregated Analysis Across Countries and World Regions

Sustainable Development, EarlyView.
ABSTRACT Transition processes towards a sustainable future benefit from historic perspectives, since feasible changes of socio‐technological conditions and processes depend on a holistic assessment of how actors are embedded in existing institutions, routines, and structures. Building on the Income–Population–Affluence–Technology equation and utilizing

Relative entropy method for measure-valued solutions in natural sciences

, 2017
In this article we describe the applications of the relative entropy framework. In particular uniqueness of an entropy solution is proven for a scalar conservation law, using the notion of measure-valued entropy solutions.
