Development of hepatocellular carcinoma organoid model recapitulating HIF-1A metabolic signature

Hypoxia is one of the main hallmarks of hepatocellular carcinoma (HCC) resulting from improper oxygenation and insufficient nourishment of the HCC microenvironment. The effect of hypoxia is mediated by hypoxia-inducible factor-1A (HIF-1A) via targeting various downstream pathways, including glycolysis, angiogenesis, and survival signaling. However, HCC cell lines in a 2-dimensional (2D) setting do

Analysis of plasmonic nanoparticles effects on the performance of perovskite solar cells through surface recombination and short-circuiting behaviors

Plasmonic photovoltaics integrate nanoparticles into the active layer to enhance power absorption. However a gap exists between simulated and experimental IV characteristics. Fabrication studies have attributed the issues to fabrication resolution, and recombination with no detailed step-by-step characterization. To address this issue, the paper presents a comprehensive optical and electrical

Hands-on analysis of using large language models for the auto evaluation of programming assignments

The increasing adoption of programming education necessitates efficient and accurate methods for evaluating students’ coding assignments. Traditional manual grading is time-consuming, often inconsistent, and prone to subjective biases. This paper explores the application of large language models (LLMs) for the automated evaluation of programming assignments. LLMs can use advanced natural language

Numerical modeling of sheathed screw connections in CFS shear walls

Screw connections within sheathed cold formed steel (CFS) shear walls experience in-plane shear that acts in a parallel direction to the sheathing's free edge. Yet, many investigations focused on connections where shear loads applied perpendicular to the sheathing's free edge. Although the modes of failure in perpendicular testing are comparable to those ones in CFS shear walls, the load

Sustainable wood composite production using cotton waste and exopolysaccharides as green binders

Burning agricultural waste is a common practice among farmers in many countries, leading to global warming and climate change. Upcycling abundant agricultural waste will prevent incineration-generated hazards and provide sustainable and eco-friendly wood. An alternative wood composite was prepared using Aspergillus niger mycelium and exopolysaccharides (EPS) as a green binder. Autoclaving and
