Organic thin-film transistors (OTFTs) with high mobility and low contact resistance have been actively pursued as building blocks for low-cost organic electronics. In conventional solution-processed or vacuum-deposited OTFTs, due to interfacial defects traps, the film has reach a certain thickness efficient charge transport. Using an ultimate monolayer of 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) molecules OTFT channel, we demonstrate remarkable electrical characteristics,...

High-grade serous tubo-ovarian cancer (HGSTOC) is characterised by extensive inter- and intratumour heterogeneity, resulting in persistent therapeutic resistance poor disease outcome. Molecular subtype classification based on bulk RNA sequencing facilitates a more accurate characterisation of this but the lack strong prognostic or predictive correlations with these subtypes currently hinders their clinical implementation. Stromal admixture profoundly affects impact molecular subtypes,...

IL1β is a central mediator of inflammation. Secretion typically requires proteolytic maturation by the inflammasome and formation membrane pores gasdermin D (GSDMD). Emerging evidence suggests an important role for in promoting cancer progression patients, but underlying mechanisms are ill-defined. Here, we have shown key driving tumor two distinct mouse models. Notably, activation inflammasome, caspase-8, as well pore-forming proteins GSDMD mixed lineage kinase domain-like protein host were...

Abstract We examine the role of financial analysts in forming institutional investors' investment decisions. In our model, a fund manager invests stock based on optimal weighting reports created by biased sell-side analyst and an unbiased buy-side analyst. The puts higher weight analyst's report when quality buyside information relative to that increases, or degree bias uncertainty about increases. Utilizing unique dataset U.S. equity funds, we find evidence supporting model predictions how...

To achieve a thin-walled structure with enhanced crashworthiness, inspired by tree fractals, new right-angle fractal of gradient hierarchical multi-cellular square bi-tubular tube (RFGHMBT) was proposed. Its energy absorption characteristics under axial impact were systematically studied using numerical simulation methods. The results show that, for both the same wall thickness and mass, high-level multicellular has higher capacity crushing force efficiency compared to low-level tube. This...
