BACKGROUND Flow diverters are used for the treatment of intracranial aneurysms. Surface modification may decrease the thrombogenicity of flow diverters but the details are unknown. Optical coherence tomography (OCT) is an intravascular imaging test with high resolution which identifies neointimal growth over stents. We compared the development of neointima in a flow diverter and stents with and...

OBJECTIVE To compare different methods of assessing energy expenditure (EE) and physical activity (PA) in people with spinal cord injury (SCI) under community-dwelling conditions. METHODS A reference standard encompassing the doubly labelled water (DLW) technique, heart rate monitoring (FLEX-HR), a multi-sensor armband (SenseWear Armband (SWA)), and two PA recall questionnaires were employed...

1. A modified heart rate (HR) method for predicting total energy expenditure (TEE) was cross-validated against whole-body calorimetry (CAL). Minute-by-minute HR was converted to energy expenditure (EE) using individual calibration curves when HR exceeded a pre-determined 'FLEX' value designed to discriminate periods of activity. ('FLEX' HR was defined as the mean of the highest HR during rest a...

C positive airway pressure (CPAP) is the standard treatment for obstructive sleep apnea (OSA).1 Different modalities of CPAP are available aiming to improve patients’ acceptance and compliance, including the conventional CPAP, auto-CPAP (APAP), bi-level positive airway pressure (bi-level PAP) and flexible CPAP or flexible pressure release CPAP (C-FLEX). Flexible pressure release CPAP is a new a...

Due to increasing demand for higher performance, greater flexibility, smaller size, and lighter weight in electronic devices, extensive studies on flexible electronic packages have been carried out. However, there has been little research on flexible packages by wafer level package (WLP) technology using anisotropic conductive films (ACFs) and flex substrates, an innovative packaging technology...

OBJECTIVES To examine the validity and reliability of the Fitbit Flex against direct observation for measuring steps in the laboratory and against the Actigraph for step counts in free-living conditions and for moderate-to-vigorous physical activity (MVPA) and activity energy expenditure (AEE) overall. METHODS Twenty-five adults (12 females, 13 males) wore a Fitbit Flex and an Actigraph GT3X+...

The main objective of this paper was to research the use of Web 2.0 techniques and freely available geospatial tools as a base for information-focused applications. The investigation was conducted, based on a prototype development of a project portal for the Fichtner Group. The methods adopted include; developing both server and client-sides of the application with Adobe Flex Builder. Toad for ...

BACKGROUND To analyse objective optical properties of the spherical and aspheric design of the same intraocular lens (IOL) model using optical bench analysis. METHODS This study entailed a comparative analysis of 10 spherical C-flex 570 C and 10 aspheric C-flex 970 C IOLs (Rayner Intraocular Lenses Ltd., Hove, UK) of 26 diopters [D] using an optical bench (OptiSpheric, Trioptics, Germany). In...

We consider modeling, predicting and evaluating the perfonnance of methods for solving PDEs in parallel architectures. We have developed a method for coarse grain partitioning of computations for parallel architectures and we apply it to three PDE applications: (a) Cholesky factorization, (b) spline collocation, and (c) an application complete from processing text input to plotting the PDE solu...

Resistive flex sensors can be used to measure bending or flexing with relatively little effort and a relativelylow budget. Their lightness, compactness, robustness, measurement effectiveness and low power consumption make these sensors useful for manifold applications in diverse fields. Here, we provide a comprehensive survey of resistive flex sensors, taking into account their working princip...
