In order to determine the characteristics of LV thrombus among heart failure patients with reduced ejection fraction (HFrEF), the present study was undertaken.Methods and Materials: This was retrospective cross-sectional study conducted from referral tertiary hospital in a year period. A total of 810 transthoracic echocardiograms were carried out in our center from January 2021 to December 2021. Forty participants had met the inclusion criteria of the study.Results: About 75% of the population was male and the mean age at diagnosis was 51 years (SD: 15). Ischemic cardiomyopathy and dilated cardiomyopathy (DCMP) found to be the most underlying cause of LVT represented (57.5% and 42.5% respectively). Hypertension, hypothyroidism, and atrial fibrillation were found to be the commonest associated risk factors of LVT, 45%, 12.5%, and 30% respectively. Simpson’s Biplane’s approach yielded a mean LVEF of 25.25 ± 6.97. 60% of the patients had a LVEF of ≤ 25%. The mean LV end-diastolic and end-systolic diameters were 59.2 ± 9.4 mm and 51 ± 8.3mm respectively. Warfarin was administered to 19 (47.5), Rivaroxaban to 8 (20), and Dabigatran to 10 (25). The most prevalent anticoagulant among the individuals in our study was warfarin. A stroke complication was found in 8 patients (20%), two of them were hemorrhagic stroke and they were on dabigatran. A Peripheral Arterial Disease (PAD) affected 6 of the patients (15%). One of those with PAD had also ischemic stroke.Conclusion: This study determines that Ischemic and Dilated cardiomyopathy were the most common cause of left ventricular thrombosis among HFrEF patients in Somalia.Keywords: left ventricular thrombus, transthoracic echocardiography, cardiomyopathy, heart failure

In the digital forensic, recovery of deleted and damaged video files play an important role in searching for the evidences. In this paper, MP4-Karver tool is proposed to recover and repair the corrupted videos. Moreover, MP4-Karver extracts frames from video for automatically screen-video to detect illegal cases instead of targeting or watching complete video. Therefore, many existing approaches such as Scalpel’s method, Garfienkel, Bi-Fragment Gap Carving, Smart Carving and Frame Based Recovery attempts to recover the videos in different ways, but most of the recovered videos are usually not complete playable. The proposed MP4-Karver focuses on recovery of video files and repair corrupted videos to complete and playable. Experimental results show that the proposed MP4-Karver effectively restores corrupted or damaged video for an improved percentage of the video restoration compared with existing tools.

Mobile forensics is an exciting new field of research. An increasing number of Open source and commercial digital forensics tools are focusing on less time during digital forensic examination. There is a major issue affecting some mobile forensic tools that allow the tools to spend much time during the forensic examination. It is caused by implementation of poor file searching algorithms by some forensic tool developers. This research is focusing on reducing the time taken to search for a file by proposing a novel, multi-pattern signature matching algorithm called M-Aho-Corasick which is adapted from the original Aho-Corasick algorithm. Experiments are conducted on five different datasets which one of the data sets is obtained from Digital Forensic Research Workshop (DFRWS 2010). Comparisons are made between M-Aho-Corasick using M_Triage with Dec0de, Lifter, XRY, and Xaver. The result shows that M-Aho-Corasick using M_Triage has reduced the searching time by 75% as compared to Dec0de, 36% as compared to Lifter, 28% as compared to XRY, and 71% as compared to Xaver. Thus, M-Aho-Corasick using M_Triage tool is more efficient than Dec0de, Lifter, XRY, and Xaver in avoiding the extraction of high number of false positive results.
