From Global to Local: Multi-Patch and Multi-Scale Contrastive Similarity Learning for Unsupervised Defocus Blur Detection.

Defocus blur detection (DBD), which aims to detect out-of-focus or in-focus pixels from a single image, has been widely applied to many vision tasks. To remove the limitation on the abundant pixel-level manual annotations, unsupervised DBD has attracted much attention in recent years. In this paper, a novel deep network named Multi-patch and Multi-scale Contrastive Similarity (M2CS) learning is proposed for unsupervised DBD.

Time-Series-Based Personalized Lane-Changing Decision-Making Model.

In recent years, autonomous driving technology has been changing from "human adapting to vehicle" to "vehicle adapting to human". To improve the adaptability of autonomous driving systems to human drivers, a time-series-based personalized lane change decision (LCD) model is proposed. Firstly, according to the characteristics of the subject vehicle (SV) with respect to speed, acceleration and headway, an unsupervised clustering algorithm, namely, a Gaussian mixture model (GMM), is used to identify its three different driving styles.

[6-Gingerol Pretreatment Alleviates Hypoxia/Reoxygenation-induced H9C2 Cardiomyocyte Injury by Inhibiting Oxidative Stress and Inflammation].

Objetive: To observe the effect of 6-gingerol (6-G) pretreatment on hypoxia/reoxygenation (H/R) induced injury in H9C2 myocardial cell and investigate its related mechanism.

Methods: The H/R model of cardiomyocytes was prepared by conventional methods. In detail, H9C2 cells were added with the nitrogen-saturated hypoxic liquid, and placed in an incubator, mixed with gas (1% O , 5% CO , 94% N ) applying for 15 min.

[Advances in the relationship between leptin and hypertensive-left ventricular hypertrophy].

Leptin is a protein hormone produced mainly by obese gene and secreted by adipose tissue and exerts the biological effects through leptin receptors. With the progress in research on the function and receptor signal transduction related leptin and leptin resistance, it has been found that leptin is associated with the development and progression of many cardiovascular diseases, such as hypertension and left ventricular hypertrophy. Some studies have reported that leptin resistance is the pathologic basis for a variety of cardiovascular diseases.
