Synthesis of Aminocyclopropanes by Redox‐Neutral Aminoalkylation
Angewandte Chemie International Edition, EarlyView.Aminocyclopropane synthesis by hydroaminoalkylation utilizing cheap, readily available starting materials is presented, offering orthogonality to commonly used methods and allowing broad functional‐group tolerance. Solvent‐mediated conditions enable the reaction of a pre‐formed hemiaminal with alkenes and alkynes.

Beyond knowledge: Cultivating noncognitive skills and attributes through anatomy education
Anatomical Sciences Education, EarlyView.Abstract Anatomy education has historically prioritized cognitive knowledge acquisition and technical skills, such as spatial awareness and manual dexterity. Noncognitive attributes, essential for early‐stage learners, such as social skills, motivation, emotional intelligence, self‐regulation, self‐efficacy, and resilience, have remained comparatively ...

Particle Swarm Optimization with non-smooth penalty reformulation for a complex portfolio selection problem [PDF]
In the classical model for portfolio selection the risk is measured by the variance of returns. It is well known that, if returns are not elliptically distributed, this may cause inaccurate investment decisions. To address this issue, several alternative

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability. Existing Safe‐and‐Sustainable‐by‐Design
