Design and Implementation of Police Intelligence Warning Management System Based on J2EE [PDF]

open access: yes, 2016
经济的发展和社会的进步,不仅给我们的生活带来了前所未有的变革,同时带来的还有违法犯罪行为呈现出智能化、隐蔽性、高发性等诸多特点。目前,对公安警情管理仍然采取以计算机为媒介,简单的利用电脑存储、传输的旧式警务工作模式。这模式早已无法适应新时期警务工作的需要,亟需开发一套新的警情预警管理系统。 针对这种现状,本文开发设计了一套基于J2EE的公安警情预警管理系统,能够实现警务相关警情的管理、分析、查询和警情预警等多功能一体的警情管理平台,为基层警务工作提供技术支撑 ...

Applicability of mitotic figure counting by deep learning: a development and pan‐cancer validation study

open access: yesFEBS Open Bio, EarlyView.
In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...
