Nuclear AGO2 exacerbates heart failure with preserved ejection fraction through myocardial ketogenesis

Kunying Jin, Y Tang, Jiabing Zhan, Yufei Zhou et autres

BACKGROUND AND AIMS: With the prevalence of Western-style high-fat diet (HFD), the incidence of heart failure with preserved ejection fraction (HFpEF) is gradually increasing. Recent studies suggested that microRNAs (miRNAs) located in different subcellular organelles could regulate lipid metabolism and cardiac function. …

An Improved Rock Method for the Chang’E-2 Microwave Radiometer Datasets

Guoping Hu, Huilei Tang, Zailong Ye, Yiping Chen et autres

Chang’E (CE) microwave radiometer (MRM) measurements provide a unique opportunity to detect the heat flow (temperature gradients) across the global Moon. However, rocks influence the brightness temperature (TB) and consequently impact the precision of the inferred temperature gradients derived from the antenna …

Oceanus Procellarum and Mare Imbrium Lava Flows: A New Comparative Look Using Microwave Radiometer Data

Roberto Bugiolacchi, Zhiguo Meng, Guoping Hu, Ulrich Mall

Abstract Chang'E‐2 passive microwave radiometer (MRM) data from two frequency channels (3 and 37 GHz) were converted into brightness temperature ( T b ) maps to study large lunar mare provinces in Oceanus Procellarum and the Imbrium basin. Twenty‐four locations were identified …

Accelerating Large Language Models through Partially Linear Feed-Forward Network

Guoping Hu, Z. Wang, Jiaju Wei, Wei Huang et autres

Large language models (LLMs) demonstrate remarkable capabilities but face deployment challenges due to their massive parameter counts. While existing compression techniques like pruning can reduce model size, it leads to significant accuracy degradation under high compression ratios. We present a novel perspective …

Inversion of the Vertical Temperature Profile and the Density of the Lunar PSR Using Chang’E-2 Microwave Radiometer Data and Diviner Data

Wenchao Zheng, Xin Ru Wang, Meng Lv, Jin Zhou et autres

The vertical temperature distribution in the permanently shaded region (PSR) has a significant impact on the temporal and spatial distribution of the cold trap. To obtain the vertical temperature profile of the PSR, an inversion method that fuses microwave and infrared brightness …
