Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Solar parity issue with flux-transport dynamo

, 2010
We investigated the dependence of the solar magnetic parity between the hemispheres on two important parameters, the turbulent diffusivity and the meridional flow, by means of axisymmetric kinematic dynamo simulations based on the flux-transport dynamo ...

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

Conservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Integrated Emission and Cost Analysis of Battery-Electric Vehicles up to 2035

Engineering Perspective
This study quantifies when battery-electric vehicles (BEVs) reach total cost of ownership (TCO) parity with their internal-combustion counterparts and characterises the cradle-to-grave greenhouse-gas (GHG) intensity trajectory to 2035.

Implementing real‐time acoustic monitoring for conservation: A case study using edge computing and satellite transmission

Conservation Science and Practice, EarlyView.
We evaluated a prototype acoustic monitoring device that performs onboard species classification and transmits detection summaries via satellite, enabling near real‐time data access from remote field sites. Deployed alongside conventional autonomous recording units at eight Northern Spotted Owl territories, the system demonstrated successful ...
