Energy-stable linear schemes for polymer-solvent phase field models
, 2018 We present new linear energy-stable numerical schemes for numerical simulation of complex polymer-solvent mixtures. The mathematical model proposed by Zhou, Zhang and E (Physical Review E 73, 2006) consists of the Cahn-Hilliard equation which describes ...

Polymer Composites, EarlyView.Different properties of biocomposites based on TPS with isosorbide as a plasticizer and green graphene filler. ABSTRACT New biocomposites of corn starch plasticized with isosorbide and filled with two types of “green” graphene with different oxygen content, 1% (G99) and 8% (G92), were processed by melt blending.

Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Numerical methods for solving the Cahn-Hilliard equation and its applicability to related Energy-based models [PDF]
, 2015 In this paper, we review some numerical methods presented in the literature in the last years to approximate the Cahn-Hilliard equation. Our aim is to compare the main properties of each one of the approaches to try to determine which one we should ...

Sustainable Development, EarlyView.ABSTRACT The Social and Solidarity Economy (SSE) offers strong potential for sustainable development in low‐income regions, yet its enterprises often operate with scarce resources, weak monitoring systems, and limited visibility. These constraints hinder both their capacity to demonstrate contributions to sustainable development (SD) and their own ...
