Comparison of 90-day case-fatality after ischemic stroke between two different stroke outcome registries using propensity score matching analysis. Acta Neurol Scand: 2011: 123: 325-331. © 2010 John Wiley & Sons A/S. Background - It has not been clarified whether the disparity in ischemic stroke outcome between populations is caused by ethnic and geographic differences or by variations in case mix. Propensity score matching (PSM) analysis can overcome some analytical problems but is rarely used in stroke outcome research. This study was to compare the ischemic stroke case-fatality between two PSM cohorts of Sweden and Korea. Methods - Prognostic variables related to baseline characteristics and stroke care were included in our PSM model. Then, we selected 7675 Swedish and 1220 Korean patients with ischemic stroke from each stroke registers and performed one-to-one matching based on propensity scores of each patient. Results - After PSM, all measured variables were well balanced in 1163 matched subjects, and the 90-day case-fatality was identical 6.2% (HR 0.997, 95%CI 0.905-1.099) in Sweden and Korea. Conclusions - No difference is found in the 90-day case-fatality in propensity score-matched Swedish and Korean patients with ischemic stroke
On the k-error linear complexity of p(m)-periodic binary sequences
No full textIn this correspondence, we study the statistical stability properties of p(m)-periodic binary sequences in terms of their linear complexity and k-error linear complexity, where 1) is a prime number and 2 is a primitive root modulo p(2). We show that their linear complexity and k-error linear complexity take a value only from some specific ranges. We then present the minimum value k for which the k-error linear complexity is strictly less than the linear complexity in a new viewpoint different from the approach by Meidl. We also derive the distribution of p(m)-periodic binary sequences with specific k-error linear complexity. Finally, we get an explicit formula for the expectation value of the k-error linear complexity and give its lower and upper bounds, when k <= [p/2].X1110sciescopu

K maximum probability attack paths generation algorithm for target nodes in networked systems
No full textAs known, security system administrators need to be aware of the security risks and abnormal behaviors in a network system. Given the exploitation probability value of each vulnerability, the cumulative probability of an attack path from an attacker to a target node can be quantified and calculated, namely as the K maximum probability attack paths for a target node. It is proposed in this paper a design to compute the K maximum probability attack paths for a given set of target nodes, where available vulnerability sets for each node in the system are built and assigned to different access flags during the computation process of attack paths, aimed at reducing the computation costs. Experimental results show that the proposed design can improve the performance on the computation of the K maximum probability attack paths for a given set of target nodes, promising and more efficient than existing algorithms to generate the attack paths
