It has been shown that a multi-walled carbon nanotube (MWCNT) can be used as the rotation enabling element for nanoelectromechanical systems. Modification of the MWCNT to create a rotational bearing in previous devices has concentrated on smaller diameter tubes and mechanical methods to create the bearing. We here investigate reactive ion etching of a MWCNT as a means to engineer nanomotor comp...

Micro- and nano-patterned fluorescent materials are important for many photonic devices and applications. In this paper, we investigate the impact of three common lithographical techniques, deposition and removal of sacrificial masks, ultraviolet ablation, and focused ion beam milling, on self-assembled fluorophores. We find that different patterning techniques can dramatically change the fluor...

Advanced heart failure, also be defined as stage D heart failure, characterized by advanced structural heart disease and marked symptoms of heart failure at rest despite dietary modification, salt restriction and maximal medical therapy including ACE inhibitors, angiotensin II receptor blockers, digitalics, diuretics and beta blockers. These patients require frequent hospitalizations and specia...

People with motor impairments often face difficulties in accessing interactive applications and services. This paper presents a tool, named FastScanner that enables motor-impaired users to work with any application running in Microsoft Windows, without the need of a posteriori modification, through the use of binary switches as an alternative to traditional input devices. Evaluation of the tool...

Femtosecond laser writing is applied to form Bragg grating waveguides in the diamond bulk. Type II waveguides are integrated with a single pulse point-by-point periodic laser modification positioned toward the edge of the waveguide core. These photonic devices, operating in the telecommunications band, allow for simultaneous optical waveguiding and narrowband reflection from a fourth-order grat...

Compound semiconductor/isolator (ZnS/silica) core/shell nanocables have been used to fabricate single nanowire-based field effect transistors. Using the surface-adsorbed charged molecules as the gate, the nanocablebased devices show potential for label-free, real-time, and sensitive detection of biological species. After chemical modification, amineand oxide-functionalized nanocables exhibit li...

Microprocessors represent a significant portion of the energy consumed in portable electronic devices. Dynamic Voltage Scaling (DVS) allows a device to reduce energy consumption by lowering its processor speed at run-time, allowing a corresponding reduction in processor voltage and energy. A voltage scheduler determines the appropriate operating voltage by analyzing application constraints and ...

conclusion mature biofilms were found to be much more resistant to antifungal agents and the host immune system than free cells. the factors responsible for high resistance included the complex architecture of biofilms, ecm, increased expression of drug efflux pumps, and metabolic plasticity. objectives the present work investigated certain aspects of the resistance of c. albicans biofilms to d...

The numerical solution of very large 3D electromagnetic field problems are challenging for various applications in the industry. In this paper, we propose a nonoverlapping domain decomposition approach for solving the 3D Maxwell equations on MIMD computers, based on a mixed variational formulation. It is especially well adapted for the solution of the Vlasov-Maxwell equations, widely used to si...
