Van der Waals heterojunctions with negative differential transconductance for broadband photodetection, multi‐valued logic, and artificial neuron

open access: yesInfoMat, EarlyView.
This work explores a combination of two ultra‐thin materials, indium selenide (InSe) and black phosphorus (BP), to create a highly efficient electronic device. This device exhibits negative differential transconductance (NDT), which is useful for developing low‐power, high‐speed logic circuits and neuromorphic (brain‐inspired) computing.

Mapping developmental transitions in mental health from mid‐ to late‐adolescence: Concurrent and longitudinal links to cognition

open access: yesJCPP Advances, EarlyView.
Abstract Background Developmental changes in mental health are mostly mapped between childhood and adolescence or childhood and adulthood. This study maps developmental transitions in mental health profiles from mid‐ to late‐adolescence, exploring how these transitions relate to cognitive function in mid‐adolescence.
