As mobile phones have evolved into ‘smartphones’, with complex operating systems running thirdparty software, they have become increasingly vulnerable to malicious applications (malware). We introduce a new design for mitigating malware attacks against smartphone users, based on a small trusted computing base module, denoted μTCB. The μTCB manages sensitive data and sensors, and provides core s...

The ability of the dehydrogenase and ring cleavage dioxygenase of the naphthalene degradation pathway to transform 3,4-dihydroxylated biphenyl metabolites was investigated. 1,2-Dihydro-1, 2-dihydroxynaphthalene dehydrogenase was expressed as a histidine-tagged protein. The purified enzyme transformed 2, 3-dihydro-2,3-dihydroxybiphenyl, 3,4-dihydro-3,4-dihydroxybiphenyl, and 3,4-dihydro-3,4-dihy...

In this paper, we first study the material stability of nanostructured materials via the continuum linearized stability analysis technique with the temperature-related Cauchy–Born (TCB) rule. As a temperature-related homogenization technique, the TCB rule considers the free energy instead of the potential so that temperature effects on material stability can be investigated. In addition, we dev...

The low temperature coefficient and high linearity of the input-output characteristics are both required for high-performance microelectromechanical systems (MEMS) capacitive accelerometers. In this work, a structural designing of a bulk MEMS capacitive accelerometer is developed for both low temperature coefficient and high linearity. Firstly, the contrary effect of the wide-narrow gaps ratio ...

This paper constructs a composite leading index for business cycle prediction based on vine copulas that capture the complex pattern of dependence among individual predictors. This approach is optimal in the sense that the resulting index possesses the highest discriminatory power as measured by the receiver operating characteristic (ROC) curve. The model specification is semi-parametric in nat...

Background: Early and non-invasive diagnosis of neonatal hyperbilirubinemia remains critical in dark skinned babies low resource settings. Objective: To assess correlation/agreement between transcutaneous bilirubin (Tcb) serum (Tsb) values full term neonates with jaundice. Methodology: An analytical cross-sectional study was conducted at the neonatology unit Essos Hospital Centre (EHC) from Jan...

Background: Transcutaneous bilirubin measurement (TcB) is widely used in term babies, but its effectiveness as well the suitable site for preterm babies still debated. Aim and Objective: To compare diagnostic accuracy of different transcutaneous sites with serum total neonate. Methods: This prospective comparative study was carried out special care baby unit at Alwahda teaching hospital-Derna-L...
