BACKGROUND AND PURPOSE Intraoperative MR imaging is being used increasingly during neurosurgical interventions. The aim of this study was to describe and classify different forms of surgically induced intracranial contrast enhancement observed during intraoperative MR examinations. METHODS A total of 51 intraoperative MR examinations were performed to assess the extent of brain tumor removal....

BACKGROUND AND PURPOSE The association of high-grade oligodendrogliomas with tumor contrast material enhancement on MR images has been reported. Some authors have even used contrast enhancement as a criterion for their oligodendroglioma grading system. The purpose of our study was to evaluate if tumor contrast enhancement is a specific finding for anaplastic oligodendroglioma. METHODS Pretrea...

Poor illumination greatly affects the quality of obtained images. In this paper, a novel convolutional neural network named DEANet is proposed on basis Retinex for low-light image enhancement. combines frequency and content information images divided into three subnetworks: decomposition, enhancement, adjustment networks, which perform decomposition; denoising, contrast detail preservation; gen...

Fingerprint images vary in quality. In order to ensure that the performance of an automatic fingerprint identification system (AFIS) will be robust with respect to the quality of input fingerprint images, it is essential to incorporate a fingerprint enhancement module in the AFIS system. In this paper, we introduce a new fingerprint enhancement algorithm which decomposes the input fingerprint i...

With the development of e-commerce, ssl protocol is more and more widely applied to various network services. It is one of key technologies to keep user's data in secure transmission via internet. This document majorly focuses on sslstrip which generates the most recent attack in the secure network connections. It strips out all the secure connections to unsecure plain connection. In this artic...

We propose and test a novel approach to the dilemma that the very networkbridging structure most likely to provide access to novel knowledge may be illsuited for the cooperation needed to successfully transfer that knowledge. We theorize that the relational dimension of social capital (e.g., tie strength) can act as a substitute for the structural benefits of network closure, and so a networkbr...

Cognitive enhancement refers to the improvement of cognitive ability in normal healthy individuals. In this article, we focus on the use of pharmaceutical agents and brain stimulation for cognitive enhancement, reviewing the most common methods of pharmacologic and electronic cognitive enhancement, and the mechanisms by which they are believed to work, the effectiveness of these methods and the...

Opponents of biomedical enhancement often claim that, even if such enhancement would benefit the enhanced, it would harm others. But this objection looks unpersuasive when the enhancement in question is a moral enhancement - an enhancement that will expectably leave the enhanced person with morally better motives than she had previously. In this article I (1) describe one type of psychological ...
