Grouping principles in direct competition

open access: yesVision Research, 2013
We (1) introduce a primed flanker task as an objective method to measure perceptual grouping, and (2) use it to directly compare the efficiency of different grouping cues in rapid visuomotor processing. In two experiments, centrally presented primes were succeeded by flanking targets with varying stimulus-onset asynchronies (SOAs).

SOCIOPSYCHODRAMA: Protagonist-centered sociopsychodrama

open access: yesRevista Brasileira de Psicodrama, 2020
Sociopsychodrama, as a group intervention method, enables directing strategies referenced to different approaches that prioritize protagonization, sociometry, or the spontaneous theater, among other probable theories.

Pd-catalysed ligand-enabled carboxylate-directed highly regioselective arylation of aliphatic acids

open access: yesNature Communications, 2017
Palladium catalysed C-H functionalization ofsp3carbons typically requires the installation and subsequent removal of a temporary directing group. Here the authors report a method allowing C-H functionalization in carboxylic acids in which the carboxylate

Electrocatalyzed direct arene alkenylations without directing groups for selective late-stage drug diversification

open access: yesNature Communications, 2023
Electrooxidation has emerged as an increasingly viable platform in molecular syntheses that can avoid stoichiometric chemical redox agents. Despite major progress in electrochemical C−H activations, these arene functionalizations generally require ...

Selective synthesis of meta-phenols from bio-benzoic acids via regulating the adsorption state

open access: yesiScience, 2023
Summary: Phenols are important building blocks widely applied in many fields. The pronounced orientational effect of the phenolic hydroxyl group makes achieving selective synthesis of meta-phenols challenging.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
