The continuous developm.nt of cyberattacks is threatening digital transform.tion endeavors worldwide and leadsto wide losses for various organizations. These dangers have proven that signature-based approaches are insufficientto prevent em.rging and polym.rphic attacks. Therefore, this paper is proposing a Robust m.licious ExecutableDetection (Rm.D) using Host-based m.chine Learning Classifier to discover m.licious Portable Executable (PE)files in hosts using Windows operating system. through collecting PE headers and applying m.chine learningm.chanism. to detect unknown infected files. The authors have collected a novel reliable dataset containing 116,031benign files and 179,071 m.lware sam.les from.diverse sources to ensure the efficiency of Rm.D *** m.st effective PE headers that can highly differentiate between benign and m.lware files were selected totrain the m.del on 15 PE features to speed up the classification process and achieve real-tim. detection form.licious executables. The evaluation results showed that Rm.D succeeded in shrinking the classification tim.to 91 m.lliseconds for each file while reaching an accuracy of 98.42% with a false positive rate equal to 1.58. Inconclusion, this paper contributes to the field of cybersecurity by presenting a com.rehensive fram.work thatleverages Artificial Intelligence (AI) m.thods to proactively detect and prevent cyber-attacks.

Background: The treatm.nt of brain m.tastases with radiotherapy has shifted to the use of Stereotactic Radio-surgery (SRS). The technical issue of expanding the treatm.nt volum. around the Gross Tum.r Volum. (GTV) is a current debate. Radiotherapy centers use variable GTV-PTV m.rgins, ranging from.one to 2 m.. m.terial and m.thods: We perform.d a dosim.tric com.arison in plans of twenty patients using three m.rgins: PTV zero, PTV1, and PTV2. We also developed im.ginary Peel volum.s. These volum.s are described as follows: Peel1 = PTV1 − GTV, Peel2 = PTV2 − GTV. Results: Our results showed that the m.an PTV volum. differed significantly across the different m.rgins (p = 0.000). The V12 of the brain significantly varied as a function of PTV m.rgin (p = 0.000). The target coverage and plan quality indices were not significantly different. The Peel volum. dosim.tric analysis showed that the m.an dose was significantly higher in the nearby norm.l brain tissue: Peel1 (p = 0.022) and Peel 2 (p = 0.013). Conclusion: According to our dosim.tric analysis, expanding the GTV into a PTV by 1 m. m.rgin is m.re convenient than 2 m..
