Numerical investigation of flow and heat transfer characteristics of supercritical CO2 in metal foam for Brayton cycle heat exchangers

The supercritical CO 2 (sCO 2 ) Brayton cycle offers great potential for compact, high-efficiency power systems, but conventional heat exchangers struggle to meet extreme thermal demands under high-parameter conditions. Open-cell metal foams offer a promising solution for heat tr...

The miR‑339‑3p/CIZ1 axis is associated with LPS‑induced microglial injury and sevoflurane‑associated cognitive impairment in aged rats

Postoperative cognitive dysfunction (POCD) substantially impairs the quality of life in elderly patients, but its underlying molecular mechanisms remain largely elusive. This study aimed to investigate miR‑339‑3p expression and its functional role in LPS‑induced microglial injury...

A self-supervised multi-task framework for downhole fault diagnosis in oil fields: Enhancing temporal feature learning under limited labels

In newly developed oil fields, the accumulation of historical labeled data is relatively scarce, making it challenging to obtain large volumes of annotated data. To address this challenge, this paper proposes a downhole fault diagnosis framework based on a complex self-supervised...

Quantifying methane emission of point-sources by integrating Aircore and DIAL-LiDAR measurements

Abstract Accurately quantifying methane (CH 4 ) emissions from intense point sources at fine spatial and temporal scales remains a significant challenge for current monitoring techniques. In this study, we present an integrated methodology that combines UAV-based AirCore sampling...

Osimertinib With or Without Chemotherapy in Advanced Non–Small Cell Lung Cancer With EGFR and Concurrent TP53 Mutations

Importance: Combination therapy has emerged as a promising therapeutic approach for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). However, its clinical benefit-risk profile remains a focus of ongoing debate. Identifying patients...
