An Adaptive Multiple Shooting Strategy for Optimal Control

Optimal Control Applications and Methods, EarlyView.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

Looking back, looking ahead: Local perspectives on landscape changes and native‐tree restoration in Madagascar

People and Nature, EarlyView.
Abstract Across sub‐Saharan Africa, tree‐based restoration efforts are dominated by exotic tree species due to their rapid biomass accumulation and short‐term economic returns. However, their limited contribution to biodiversity and ecosystem functioning has renewed interest in native‐tree restoration as a more sustainable strategy.

Bringing social cohesion into forest landscape restoration: Identifying future pathways toward more integrated social‐ecological restoration

People and Nature, EarlyView.
Abstract Forest Landscape Restoration (FLR) is increasingly recognized as a key strategy to address land degradation, biodiversity loss and climate change. However, its long‐term success depends not only on ecological outcomes but also on social processes that shape restoration implementation and sustainability.

Extruder‐based 3D printing of eco‐friendly polymers

Polymer International, EarlyView.
Eco‐friendly polymers, such as biodegradable and recycled materials, offer significant potential for the production of high‐quality 3D‐printed components, provided that their properties and characteristics meet the requirements of extruder‐based 3D printing.

Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

Journal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

PLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...
