Heat-Fluid-Solid-Coupled Model for Flue Gas Displacement of CH in Coal Seams and Its Applications.

The objective of this study was to evaluate the effect of injecting flue gas (CO, N, and O) originating from coal-fired power plants into a coal seam on CH extraction and CO geological storage. To this end, a multifield thermal-fluid-solid-coupled mathematical model of flue gas injection extraction was established. The results showed that with the increase in time increase, the volume concentration of CH decreased, but the CO, N, and O increased.

A Lateral Line Specific Mucin Involved in Cupula Growth and Vibration Detection in Zebrafish.

The lateral line system in fish is crucial for detecting water flow, which facilitates various behaviors such as prey detection, predator avoidance, and rheotaxis. The cupula, a gelatinous structure overlaying the hair cells in neuromasts, plays a key role in transmitting mechanical stimuli to hair cells. However, the molecular composition of the cupula matrix remains poorly understood.

Overview of Deep Learning and Nondestructive Detection Technology for Quality Assessment of Tomatoes.

Tomato, as the vegetable queen, is cultivated worldwide due to its rich nutrient content and unique flavor. Nondestructive technology provides efficient and noninvasive solutions for the quality assessment of tomatoes. However, processing the substantial datasets to achieve a robust model and enhance detection performance for nondestructive technology is a great challenge until deep learning is developed.

Degradation of Methylene Blue by Ozone Oxidation Catalyzed by the Magnetic MnFeO@CoS Nanocomposite.

In this study, the MnFeO@CoS magnetic nanocomposite was prepared by a two-step hydrothermal method and used to catalyze the ozone oxidation degradation of methylene blue. It was characterized by XRD, EDS, SEM, FT-IR, and XPS. The results showed that the introduction of CoS made MnFeO grow uniformly on CoS nanosheets, which effectively prevented the agglomeration of MnFeO.

Measures to prevent esophageal stenosis are necessary after endoscopic submucosal dissection for early esophageal cancer lesions with a circumferential ratio of 75%-99%: a retrospective case analysis.

Purpose: Endoscopic submucosal dissection (ESD) is currently one of the most curative treatments for early esophageal cancer. We conducted a retrospective case analysis to identify the characteristics of early esophageal cancer that indicate esophageal stenosis prevention measures. Our aim was to provide a reference for clinical decision-making.
