Cleavage of non-polar C(sp 2)‒C(sp 2) bonds in cycloparaphenylenes via electric field-catalyzed electrophilic aromatic substitution
Novel methodologies for cleaving inherently inert C(sp 2)‒ C(sp 2) bonds are desirable. Here, the authors report the use of an oriented electric field to cleave C(sp 2)‒ C(sp 2) in cycloparaphenylenes via electrophilic aromatic substitution.

Dopamine Transporter Imaging‐Based Radiomics for Predicting 4‐Year Motor Progression (Unified Parkinson's Disease Rating Scale Part III) in Parkinson's Disease
ABSTRACT Background Parkinson's disease (PD) shows substantial heterogeneity in motor progression, and reliable early prediction remains challenging. Dopamine transporter (DAT) imaging reflects presynaptic dopaminergic degeneration but is typically analyzed using simplified metrics that may not…

The influence of visual deprivation on the development of the thalamocortical network: Evidence from congenitally blind children and adults
The thalamus is heavily involved in relaying sensory signals to the cerebral cortex. A relevant issue is how the deprivation of congenital visual sensory information modulates the development of the thalamocortical network. The answer is unclear because previous studies on this topic did not…
