INTRODUCTION The brain is responsible for cognition, behavior, and much of what makes us uniquely human. development the a highly complex process, this process reliant on precise regulation molecular cellular events grounded in spatiotemporal transcriptome. Disruption can lead to neuropsychiatric disorders. RATIONALE regulatory, epigenomic, transcriptomic features human have not been comprehensively compiled across time, regions, or cell types. Understanding etiology disorders requires...
Genes implicated in neuropsychiatric disorders are active human fetal brain, yet difficult to study a longitudinal fashion. We demonstrate that organoids from pluripotent cells model cerebral cortical development on the molecular level before 16 weeks postconception. A multiomics analysis revealed differentially genes and enhancers, with greatest changes occurring at transition stem progenitors. Networks of converging gene enhancer modules were assembled into six four global patterns...
The hippocampal-entorhinal system supports cognitive functions, has lifelong neurogenic capabilities in many species, and is selectively vulnerable to Alzheimer's disease. To investigate potential cellular diversity, we profiled single-nucleus transcriptomes five subregions humans, macaques, pigs. Integrated cross-species analysis revealed robust transcriptomic histologic signatures of neurogenesis the adult mouse, pig, macaque but not humans. Doublecortin (DCX), a widely accepted marker...
Gene expression levels vary across developmental stage, cell type, and region in the brain. Genomic variants also contribute to variation expression, some neuropsychiatric disorder loci may exert their effects through this mechanism. To investigate these relationships, we present BrainVar, a unique resource of paired whole-genome bulk tissue RNA sequencing from dorsolateral prefrontal cortex 176 individuals prenatal postnatal development. Here identify common that alter gene (expression...

Abstract Dithiocarbonate‐based non‐hygroscopic polymers with a glass transition temperature ( T g ) and polydispersity index (PDI) of ≈4 °C 1, respectively, are synthesized through living cationic ring‐opening polymerization. These liquid‐state characterized by monodispersity based on the low PDI, rendering remarkable miscibility perovskite precursors without aggregation. Accordingly, these added to solar cells (PSCs) enhance their power conversion efficiency (PCE). The PCE reference PSCs...
Abstract This review addresses the self‐healing effects in perovskite solar cells (PSCs), emphasizing significance of chemical and physical bonding as core mechanisms.

Physiological measures taken during message presentation, and self-report after each. Results show that increased complexity led higher self-reported physiological arousal, better attitudes toward the messages overall their nonclaim components. There no differences claims made at each level Structurally complex also freely recalled more often than simple messages. The...

SUMMARY The hippocampal-entorhinal system is comprised of functionally distinct subregions collectively critical for cognition, and selectively vulnerable to aging pathological processes. To gain insights into neuronal non-neuronal populations within this system, we performed single-nucleus transcriptional profiling from five human subregions. We found that transcriptomic diversity excitatory neurons across these reflected the molecular transition three-layered archicortex six-layered...
Using robust, integrated analysis of multiple genomic datasets, we show that genes depleted for non-synonymous de novo mutations form a subnetwork 72 members under strong selective constraint. We further this is preferentially expressed in the early development human hippocampus and enriched mutated neurological Mendelian disorders. thus conclude carefully orchestrated developmental processes are constraint brain development, perturbations caused by mutation have adverse outcomes subject to...
Perovskite solar cells (PSCs) are regarded as the next-generation thin-film energy harvester, owing to their high performance. However, there is a lack of studies on encapsulation technology, which critical for resolving shortcomings, such degradation by oxygen and moisture. It determined that moisture intrusion heat trapped within encapsulating cover glass PSCs influenced operating stability devices. Therefore, we improved barrier ability releasing capability in passivation adding...
Passivation films, commonly referred to as solid–electrolyte interphase and cathode–electrolyte (CEI), are essential for the operation of rechargeable batteries due their positive impact on electrochemical performances.

We introduce a family of rotationally invariant random matrix ensembles characterized by parameter λ. While λ = 1 corresponds to well-known critical ensembles, we show that ≠ describes 'Lévy-like' power-law eigenvalue densities. For > the density is bounded, as in Gaussian but < densities with long tails. In particular, model allows us evaluate, terms novel orthogonal polynomials, correlations for Lévy-like ensembles. These differ qualitatively from those either or
