Mobile sensor nodes (MSNs) are equipped with locomotive can move around after having been deployed. They are equipped with limited energy. A large portion of energy is drained during the traversal. In order to extend the life time of a MSN, the traveling distance must be minimized. Region of interest (ROI) is covered with multiple MSNs using coverage based pattern movement. When a group of MSNs...

Ultrasound contrast agents (UCAs) designed by the conventional composition-based strategy, often suffer from relatively low ultrasound utilization efficiency. In this report, a structure-based design concept of double-scattering/reflection in a single nanoparticle for enhancing ultrasound imaging has been proposed. To exemplify this concept, a rattle-type mesoporous silica nanostructure (MSN) w...

1 Orientation redesign improves employee satisfaction, retention What do you do when your orientation program isn’t effective in educating and retaining OR staff? Carol Pehotsky, MSN, RN, ACNS-BC, CPAN, director of peri-operative education at the Cleveland Clinic in Cleveland, Ohio, found herself in that position 3 years ago. “We blew it all up and started over,” she says. Pehotsky embarked on ...

The aldol reaction catalyzed by an amine-substituted mesoporous silica nanoparticle (amine-MSN) surface was investigated using a large molecular cluster model (Si392O958C6NH361) combined with the surface integrated molecular orbital/molecular mechanics (SIMOMM) and fragment molecular orbital (FMO) methods. Three distinct pathways for the carbinolamine formation, the first step of the amine-cata...

This study measures the frequency in which search engines update their indices. Therefore, 38 websites that are updated on a daily basis were analysed within a time-span of six weeks. The analysed search engines were Google, Yahoo and MSN. We find that Google performs best overall with the most pages updated on a daily basis, but only MSN is able to update all pages within a time-span of less t...

Dopaminergic modulation produces a variety of functional changes in the principal cell of the striatum, the medium spiny neuron (MSN). Using a 189-compartment computational model of a ventral striatal MSN, we simulated whole cell D1- and D2-receptor-mediated modulation of both intrinsic (sodium, calcium, and potassium) and synaptic currents (AMPA and NMDA). Dopamine (DA) modulations in the mode...

Multifunctional nanoplatforms based onmesoporous silica nanoparticles (MSNs) have recently shown great promise in drug delivery and therapy. Herein, a multifunctional nanoplatform based on MSNs is fabricated by a modified micro-emulsion method for drug delivery and imaging-guided chemo/photodynamic synergistic therapy. Carbon dots (C-dots) and a photosensitizer, rose bengal (RB), are embedded i...
