Malware often contains hidden behavior which is only activated when properly triggered. Well known examples include: the MyDoom worm which DDoS's on particular dates, keyloggers which only log keystrokes for particular sites, and DDoS zombies which are only activated when given the proper command. We call such behavior trigger-based behavior. Currently,(More)
Automatic analysis of malicious binaries is necessary in order to scale with the rapid development and recovery of malware found in the wild. The results of automatic analysis are useful for creating defense systems and understanding the current capabilities of attackers. We propose an approach for automatic dissection of malicious binaries which can answer(More)
214 patients with single vessel disease were followed-up for 1-78 months (mean 48 months). Incidence of sudden death was studied in relation to coronary artery lesions, left ventricular wall motion and ventricular arrhythmias found during ambulatory ECG recording. Incidence of sudden death was 11% (16 of 144) in patients with lesions of the left anterior(More)
Ventricular fibrillation and sudden death are rare phenomena in nonischemic ventricular arrhythmia, particularly in arrhythmogenic right ventricular cardiomyopathy. In most instances electrophysiologic studies help to assess the risk of sudden death, but sometimes programmed ventricular stimulation is unsuccessful. Among 48 patients with ventricular(More)
The antiarrhythmic efficacy of a slow-release form of metoprolol was studied in 13 male coronary patients, mean age 47 years (39-59 years) with frequent and complex ventricular arrhythmias (couplets, salvos). The prospective, single-blind trial was based on 24 h Holter monitoring. In each case, the extent of coronary heart disease and the presence of old(More)
BACKGROUND In arrhythmogenic right ventricular disease it is difficult to find an imaging technique not only to suppose but to diagnose this disease. PATIENTS AND METHOD In order to assess the value of selective right ventricular angiography in 104 patients with arrhythmogenic right ventricular disease (n = 53), WPW-syndrome (n = 2), sarcoidosis (n = 1),(More)
Modern processors, especially VLIW processors, often have the ability to execute multiple instructions simultaneously. Taking advantage of this capability is crucial for high performance software applications. Software pipelining is a technique designed to increase the level of parallelism in loops. We propose a new approach to software pipelining based on(More)
In this case report, the hospitalization of a 34-year-old woman with a history of heart disease is described. Arrhythmias and precordial chest pain led to her admission to the coronary care unit. Different therapeutic trials failed. Finally it became obvious that all tachycardias documented by the arrhythmia monitoring system were artifacts, produced by(More)
102 patients with angiographically documented double vessel coronary artery disease were followed for 1-83 months (mean: 42 months). Incidence of sudden death was studied in relation to location and severity of coronary artery lesions, left ventricular wall motion and ventricular arrhythmias found during long-term ECG monitoring. The incidence of sudden(More)
The incidence and pattern of ventricular arrhythmias recorded with 24 h ambulatory monitoring were studied in 144 patients with angiographically documented stenoses (greater than or equal to 75%) or occlusions of the left anterior descending coronary artery (LAD) and were related to left ventricular wall motion abnormalities. Ambulatory monitoring was(More)
