Thousands of Qatari genomes inform human migration history and improve imputation of Arab haplotypes
( Nature Research , 2021 , Article)Arab populations are largely understudied, notably their genetic structure and history. Here we present an in-depth analysis of 6,218 whole genomes from Qatar, revealing extensive diversity as well as genetic ancestries ... -
Threat and vulnerability risk assessment for existing subway stations: A simplified approach
( Elsevier Ltd , 2018 , Article)People use infrastructure systems mostly without realizing how important these systems are until an attack or damage occurs and results in casualties or causes discomfort or inconvenience. Even though there have been ... -
A Threat-Specific Risk Evaluation Tool For Cloud Environments
(2018 , Professional Masters Project)With the spread of using cloud computing; both as organizations and individual, it has become a target for attackers. The cloud environment has several weaknesses that pose threats to its users’ assets. To assess any type ... -
Threat-specific security risk evaluation in the cloud
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Existing security risk evaluation approaches (e.g., asset-based) do not consider specific security requirements of individual cloud computing clients in the security risk evaluation. In this paper, we propose a threat-specific ... -
ThreatBased Security Risk Evaluation in the Cloud
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Research ProblemCyber attacks are targeting the cloud computing systems, where enterprises, governments, and individuals are outsourcing their storage and computational resources for improved scalability and dynamic ... -
ThreatRiskEvaluator: A Tool for Assessing Threat-Specific Security Risks in the Cloud
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In cloud computing, security risks posed to individual clients are different based on their specific security requirements. In current practice, cloud providers usually apply generic protection mechanisms that may not be ... -
The Three CARMA Sisters: So Different, So Similar: A Portrait of the Three CARMA Proteins and Their Involvement in Human Disorders
( Wiley Periodicals, Inc. , 2014 , Article)Initially identified by their ability to modulate the functional activity of BCL10, the three CARMA proteins, CARMA1, -2, and -3, have recently themselves taken a leading role on the stage of molecular medicine. Although ... -
Three Dimensional Analysis Of Skeletal Structures Considering Cracking
( Qatar University , 1992 , Article)A three dimensional computer model has been developed to analyze space structures containing cracked members. A new stiffness matrix for cracked space members has been obtained. This model takes into consideration crack ... -
