The discovery of recent zero-day exploits against Microsoft Word, Adobe Flash Player and Internet Explorer demonstrate that return-oriented programming (ROP) is the most severe threat to software system security. Microsoft’s 2013 Software Vulnerability Exploitation trend report found that 73% of all vulnerabilities are exploited via ROP. The core idea of ROP is to exploit the presence of so-cal...

OBJECTIVE To develop a birth weight (BW), gestational age (GA), and postnatal-weight gain retinopathy of prematurity (ROP) prediction model in a cohort of infants meeting current screening guidelines. METHODS Multivariate logistic regression was applied retrospectively to data from infants born with BW less than 1501 g or GA of 30 weeks or less at a single Philadelphia hospital between Januar...

Retinopathy of prematurity (ROP) is one of the most important causes of childhood blindness worldwide. The trend of ROP in Malaysia was unclear because there was no national registry before 2002. The purpose of this study is to analyze ROP students of different ages in the schools for the blind in Malaysia in order to evaluate the trend of ROP from 1992 to 2001. Data were obtained from a previo...

Fine-grained Address Space Randomization has been considered as an effective protection against code reuse attacks such as ROP/JOP. However, it only employs a one-time randomization, and such a limitation has been exploited by recent just-in-time ROP and side channel ROP, which collect gadgets on-the-fly and dynamically compile them for malicious purposes. To defeat these advanced code reuse at...

Over the past few years, return-oriented programming (ROP) attacks have emerged as a prominent strategy for hijacking control of software. The full power and flexibility of ROP attacks was recently demonstrated using just-intime ROP tactics (JIT-ROP), whereby an adversary repeatedly leverages a memory disclosure vulnerability to identify useful instruction sequences and compile them into a func...

Abstract Hot-point drills have been widely used for drilling boreholes in glaciers, ice caps and sheets. A hot-point drill melts through the thermal head at its bottom end. Penetration occurs a close-contact melting (CCM) process, which is melted, meltwater squeezed out by exerted force applied on head. During drilling, thin water film formed to separate from surrounding ice. For drill, rate of...
