This paper introduces a novel approach to user event reconstruction by showing the practicality of generating and implementing signature-based analysis methods to reconstruct high-level user actions from a collection of low-level traces found during a post-mortem forensic analysis of a system. Traditional forensic analysis and the inferences an investigator(More)
This paper expands upon the finite state machine approach for the formal analysis of digital evidence. The proposed method may be used to support the feasibility of a given statement by testing it against a relevant system model. To achieve this, a novel method for modeling the system and evidential statements is given. The method is then examined in a case(More)
This paper describes a methodology for the reconstruction of digital events by comparing states captured in time. Microsoft Windows Restore Point data is used to illustrate how to organize captured state information into a useful timeline of user and system events. It is shown that by comparing consecutive states, events can be uncovered that would(More)
The Microsoft Windows registry is an important resource in digital forensic investigations. It contains information about operating system configuration, installed software and user activity. Several researchers have focused on the forensic analysis of the Windows registry, but a robust method for associating past events with registry data values extracted(More)
This paper proposes a novel method for checking the consistency of forensic registry artifacts by gathering event information from the artifacts and analyzing the event sequences based on the associated timestamps. The method helps detect the use of counter-forensic techniques without focusing on one particular counter-forensic tool at a time. Several(More)
BACKGROUND B7-H3 exhibits altered expression in various cancers. However, the correlation between B7-H3 expression and prognosis of cancer patients remains controversial. Therefore, we elicit a meta-analysis to investigate the potential value of B7-H3 in the prognostic prediction in human cancers. MATERIALS AND METHODS We searched PubMed (last update by(More)
This study was designed to perform an acceptable prognostic nomogram for acute myeloid leukemia. The clinical data from 311 patients from our institution and 165 patients generated with Cancer Genome Atlas Research Network were reviewed. A prognostic nomogram was designed according to the Cox's proportional hazard model to predict overall survival (OS). To(More)
INTRODUCTION This pooled analysis study aimed to reveal the prognostic relevance of microRNAs (miRNAs) in patients with diffuse large B-cell lymphoma (DLBCL). MATERIALS AND METHODS We examined the impact of miRNAs on clinical outcome. Eligible studies were identified and quality assessed using multiple search strategies. Data were extracted from included(More)
