Mind wandering has been argued to be beneficial for breaking through mental impasses, which leads to better creative performance upon a second attempt (i.e., the incubation effect). However, the evidence is inconsistent. Different from the propensity for mind wandering that has been the focus of past studies, in this study we further examined the role of diversity (i.e., non-repetitiveness of mind wandering respective to its content) and types of mind wandering along the dimensions of intentionality and awareness during incubation when engaging in a 0-back task (a mind wandering-prone conditio

Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), stroke, and depression, are marked by progressive neuronal dysfunction and loss, yet current treatments remain largely symptomatic with limited disease-modifying efficacy. Glucagon-like peptide-1 (GLP-1), an incretin hormone traditionally associated with metabolic regulation, has emerged as a promising neuroprotective agent. Its receptor, GLP-1R, is expressed in key brain regions implicated in cognition, emotion, and motor control, including the hippocampus, frontal cortex, and substantia nigra. GLP-1R a

Immune checkpoint inhibitors (ICIs) targeting PD-1 and CTLA-4 have achieved groundbreaking clinical success in multiple cancers; however, a large proportion of patients experience primary or acquired resistance. This review synthesizes the complex mechanisms underlying resistance to PD-1/CTLA-4 blockade and surveys emerging strategies to overcome them. Resistance arises from multifaceted interactions among tumor-intrinsic alterations (e.g., epigenetic silencing of antigen presentation machinery via EZH2/PRC2, oncogenic pathway-driven upregulation of PD-L1, genetic loss of IFNγ pathway componen

This paper explores the effect of board diversity on environmental, social, and governance (ESG) performance in Korean-listed firms using regression analysis. Our findings reveal that an increased board size significantly correlates with higher ESG scores when combined with other board diversity dimensions. The presence of female directors on boards was found to have a significant effect on environmental and social components of ESG performance. Age diversity exhibits a negative association with ESG scores, emphasizing potential disruptions from intergenerational differences. Foreign directors

This paper forms part of Mirror Programme, Volume I: Observerhood. Mirror Mathematics II develops the formal threshold layer of the Mirror Mathematics arc. Building on Mirror Mathematics I, it asks when a self-model becomes observer-relevant rather than merely predictive, self-referential or descriptive. The paper introduces a minimal Mirror observer predicate grounded in self-model reliability, action-guidance, cost-sensitive repair and positive viability coupling under perturbation. The central condition is expressed through a salience functional measuring whether the expected viability bene

Abstract Triple‐junction solar cells theoretically outperform their double-junction and single‐junction counterparts in power conversion efficiency, yet practical perovskite–perovskite–silicon devices have fallen short of both theoretical limits and commercial targets. To address surface defects in the top perovskite junction, we introduce a piperazine-1,4-diium chloride treatment, which replaces less stable lithium fluoride. For interfacing the top and middle perovskite junctions, we optimize the size of gold nanoparticles deposited on atomic layer-deposited tin oxide for best ohmic contactin
