Associations of red and processed meat with survival after colorectal cancer and differences according to timing of dietary assessment
colorectal cancer molecular subtypes mortality red and processed meat survival
2018/11/23
Background: Little is known about the prognostic impact of red and processed meat intake or about changes in consumption after a diagnosis of colorectal cancer (CRC).
Timing attacks are usually used to attack weak computing devices such as smartcards. We show that timing attacks apply to general software systems. Specifically, we devise a timing attack against Open...
Exposing private information by timing web applications
web applications private information
2015/8/5
We show that the time web sites take to respond to HTTP requests can leak private information, using two different types of attacks. The first, direct timing directly measures response times from a we...
