We consider a model of law enforcement where homogenous, risk neutral, and corruptible inspectors are responsible for monitoring …rms’ adoption of pollution prevention technology. A welfare maximizing government can implement appropriate wage policies to prevent collusion, but we …nd that governments characterized by high administrative costs in administrating …nes, or by a low ability to spot ...

Most memory corruption attacks and Internet worms follow a familiar pattern known as the control-data attack. Hence, many defensive techniques are designed to protect program control flow integrity. Although earlier work did suggest the existence of attacks that do not alter control flow, such attacks are generally believed to be rare against real-world software. The key contribution of this pa...

Our experiences interfacing Python with optimization software are presented. The same work was done using extension programming and scripting. Due to the nature of the C libraries we were using, we found problems related to memory corruption and C namespace collisions when we used the libraries as Python extensions. For our application and the software we are interfacing to, we found that using...

Studies have shown that packet reordering is common, especially in satellite networks where there are link level retransmissions and multipath routing. Moreover, traditional satellite networks exhibit high corruption rates causing packet losses. Reordering and corruption of packets decrease the TCP performance of a network, mainly because it leads to overestimation of the congestion in the netw...

Memory corruption vulnerabilities are still a severe threat for software systems. To thwart the exploitation of such vulnerabilities, many different kinds of defenses have been proposed in the past. Most prominently, Control-Flow Integrity (CFI) has received a lot of attention recently. Several proposals were published that apply coarse-grained policies with a low performance overhead. However,...

‎ introduction: controversial results have been reported about the effect of morphine and stress on learning and spatial memory in rodents. there are very few studies about the effects of ultra low doses of morphine on memory. in this study, effects of acute administration of low and usual doses of morphine on memory formation and retention in the presence and absence of repeated stress were in...

Exercise has been proposed for the treatment of traumatic brain injury (TBI). However, the proper intensity of exercise in the early phase following a severe TBI is largely unknown. To compare two different treadmill exercise intensities on the cognitive function following a severe TBI in its early phase, rats experienced a controlled cortical impact (CCI) and were forced to treadmill exercise ...
