Biomolecular motors are tiny engines that transport material at the microscopic level within biological cells. It has been proposed that many such motors operate, at least in part, by a Brownian ratchet mechanism. Since biomolecular motors typically transport cargo that are much larger than themselves, one would expect the speed of such a motor to be severely limited by the small diffusion coef...

In recent years, there has been rapid urbanization worldwide, resulting in both benefits and problems. Sustainable urbanization has become an important aspect in promoting sustainable development. Existing studies have introduced various methodologies to guide urbanization towards sustainable practices. The application of these methods has contributed to improving urban sustainability. To furth...

Spoofing with photograph or video is one of the most common manners to attack a face recognition system. In this paper, we present a non intrusive and real time method to address this problem, based on fusion of thermal imaging and skin elasticity of human face. In this technique, face images is captured using camera sensor and thermal sensor at the same time. Before capturing the images, user ...

This research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. Heat conduction equation in cylindrical coordinate system is solved. Thermal conductivity coefficient is graded along the radial direction. By considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...

BACKGROUND Whole blood viscoelastic tests such as the fibrin-based thromboelastometry (ROTEM(®)) test FIBTEM are increasingly used in the perioperative setting to quickly identify deficits in fibrin quality, and to guide hemostatic therapy. The recently developed FibScreen2 test of the ReoRox(®) method, based on free oscillation rheometry, also provides an evaluation of fibrin clot quality. To ...

BACKGROUND The purpose of this study is to evaluate the intima-media thickness (IMT) and arterial elasticity of the common carotid artery (CCA) in patients with cerebral small vessel disease (SVD) by applying radiofrequency (RF) ultrasound technology. METHODS Fifty SVD subjects (SVD group) and fifty-three matched controls (Control group) were enrolled in the study. Structural and functional c...

Iterative substructuring methods with Lagrange multipliers for the elliptic system of linear elasticity are considered. The algorithms belong to the family of dual-primal FETI methods which was introduced for linear elasticity problems in the plane by Farhat et al. [2001] and then extended to three dimensional elasticity problems by Farhat et al. [2000]. In dual-primal FETI methods, some contin...
