This paper reports on implementation and high-Q operation of thick bulk mode VHF capacitive disk resonators with reduced motional resistance. Single crystal silicon (SCS) disk resonators as thick as 18 m with capacitive gap size of 160nm (aspect ratio>110) are fabricated on SOI substrates using a three-mask version of the HARPSS on SOI process. The new resonator design with increased number of ...

OBJECTIVE To determine the cost-effectiveness of averting the burden of disease. We used secondary population data and metaanalyses of various government-funded services and interventions to investigate the costs and benefits of various levels of treatment for rheumatoid arthritis (RA) and osteoarthritis (OA) in adults using a burden of disease framework. METHOD Population burden was calculat...

objectives the aim of this study was to study the incremental cost-effectiveness ratio associated with the use of heat and moisture exchangers (hme) filter to prevent vap compared with the heated humidifiers (hh) presently adopted by intensive care unit (icu) services within the brazilian healthcare unified system. patients and methods this study was a cost-effectiveness analysis (cea) comparin...

Recent information about osteoporosis treatments and their nonfracture side effects suggests the need for a new cost-effectiveness analysis. The authors estimate the cost effectiveness of screening women for osteoporosis at age 65 and treating those who screen positive with hormone replacement therapy (HRT), raloxifene, or alendronate. A Markov model of osteoporosis disease progression simulate...

BACKGROUND Worldwide, respiratory syncytial virus (RSV) is considered to be the most important viral cause of respiratory morbidity and mortality among infants and young children. Although no active vaccine is available on the market yet, there are several active vaccine development programs in various stages. To assess whether one of these vaccines might be a future asset for national immuniza...

Effectiveness of oil spill dispersants containing lecithin/Tween 80 (L/T) blends in ethanol was measured as a function of L:T ratio, surfactant:solvent ratio, solvent composition, and dispersant:oil ratio (DOR) using baffled flask dispersion effectiveness tests. Optimal L:T ratios are between 60:40 and 80:20 (w/w); at higher L:T ratios, effectiveness is limited by high interfacial tension, whil...

We evaluated four methods for computing confidence intervals for cost-effectiveness ratios developed from randomized controlled trials: the box method, the Taylor series method, the nonparametric bootstrap method and the Fieller theorem method. We performed a Monte Carlo experiment to compare these methods. We investigated the relative performance of each method and assessed whether or not it w...

OBJECTIVE The prevention of depression is of growing interest to researchers and policy makers. However, the question of whether interventions designed to prevent depression provide value for money at a population level remains largely unanswered. The current study assesses the cost-effectiveness of two indicated interventions designed to prevent depression: a brief psychological intervention b...

Thermal noise is a limit to precision measurement in many fields. The relationship of the quality factor of mechanical systems to the thermal noise has compelled many researchers to search for materials with low mechanical losses. Typical measurements of mechanical quality factor involve exciting a mechanical resonator and observing the exponential decay of the amplitude under free oscillations...
