Sliding-ferroelectric order imprinted onto excitonic and valley responses in van der Waals heterostructures

Ferroelectricity driven by interlayer sliding provides a distinct route to nonvolatile control in van der Waals (vdW) heterostructures, yet resolving stacking-dependent ferroelectric states and their local interfacial consequences remains challenging. Here, we report that bilayer...

Appetitive trait profiles in late life: links to eating disorder psychopathology and psychosocial well-being

Abstract Objective Appetitive traits shape eating behaviors across the lifespan, yet their patterns and health correlates in later life remain poorly understood. This study used latent profile analysis (LPA) to identify distinct profiles of appetitive traits among older adults an...
