Network traffic classification plays a fundamental role in network management and services. Given error accumulation in traditional DAGSVM (Directed Acyclic Graph-Support Vector Machine) algorithm, we propose an improved DAGSVM classification method using two different possibility metrics in this paper. Differing from traditional DAG-SVM, the improved DAG-SVM algorithm eliminates one class only un...

Prostate cancer (PCa) is one of the most common primary malignancies in humans and the second leading cause of cancer-specific mortality among Western males. Computer-aided detection (CAD) systems have been developed for accurate and automated PCa detection and diagnosis, but the diagnostic accuracy of different CAD systems based on magnetic resonance imaging (MRI) for PCa remains controversial. T...

Background Left bundle branch block (LBBB) is a common complication of the transcatheter aortic valve replacement (TAVR), and its impact on prognosis is controversial. Method A comprehensive electronic search was conducted in databases (PubMed, Embase, Cochrane Library, and The Web of Science), from the date of database establishment till March 2021, to screen for studies on new onset LBBB after ...

Developing sustainable environmental policies in ecologically fragile and deeply impoverished areas is a global challenge. Desertification has caused serious environmental and socioeconomic issues. It is important to reveal the mechanisms of environmental policies when balancing desertification control and poverty alleviation. This study used comparative analysis and trend analysis methods and ass...

Urban ecosystem dysfunction, habitat fragmentation, and biodiversity loss caused by rapid urbanization have threatened sustainable urban development. Urban habitat quality is one of the important indicators for assessing the urban ecological environment. Therefore, it is of great practical significance to carry out a study on the driving mechanism of urban habitat quality and integrate the results...

Crowd counting on the drone platform is an interesting topic in computer vision, which brings new challenges such as small object inference, background clutter and wide viewpoint. However, there are few algorithms focusing on crowd counting on the drone-captured data due to the lack of comprehensive datasets. To this end, we collect a large-scale dataset and organize the Vision Meets Drone Crowd C...

Based on National Oceanic and Atmospheric Administration/Advanced Very High Resolution Radiometer (NOAA/AVHRR) remote sensing and Cross Calibrated Multi Platform (CCMP) wind field data from 2007 to 2019, oceanographic conditions are analysed, respectively, in the Source Area (SA) and Typical Bloom Area (TBA) of Ulva prolifera (U. prolifera) in the west of the Southern Yellow Sea (SYS) using Sea Su...

A novel P–N based, flame retardant ammonium salt of pentaethylenehexamine octa (methylene-phosphoric acid) (APHOMPA) was synthesized in this study. The structure of the prepared material flame retardant contains eight reactive ammonium phosphorus groups and was characterized by 1H NMR, 13C NMR, 31P NMR, and (Fourier-transform infrared) FT-IR. The results showed that cotton fabrics finished with th...
