Resonators serve as essential components in radio-frequency (RF) electronics, forming the backbone of filters and tuned amplifiers. However, traditional solid state or mechanic implementations of resonators and filters tend to be bulky and power hungry, limiting the versatility of communications, guidance, and avionics systems. Microelectro-mechanical systems (MEMS) are promising replacements f...

The Aggregate Demand – Aggregate Supply framework has dominated intermediate macroeconomics textbooks since the 1980s. However, there have been 2007). In spite of these criticisms, the ADAS framework had continued to dominate the textbooks, with little or no response to these criticisms. This paper reviews the main criticisms of the ADAS framework, and then focuses on Gregory Mankiw's presentat...

In this paper we will analyze how retirement behavior is affected by a worker’s firm-specific or general training history. This relationship is studied in the perspective of upward sloping earning profiles. Moreover, we examine the effects of technological change on the likelihood of early retirement. Using U.S. data from the National Longitudinal Survey of Older Men, we find that workers with ...

We decompose the term structure of expected equity returns into (1) the real short rate, (2) a premium for holding real long-term bonds, or the real duration premium, the excess returns of nominal long-term bonds over real bonds which reflects (3) expected inflation and (4) inflation risk, and (5) a real cashflow risk premium, which is the excess return of equity over nominal bonds. The shape o...

The fact that the implied volatility smiles for equity indices are strongly downward sloping, while the typical individual stock exhibits either a flat or even an upward sloping smile is sometimes considered puzzling. We show that this effect can easily be generated in a simple and parsimonious two-factor stochastic volatility model in the spirit of Bates (2000). From a theoretical perspective ...

Three ways in which near-boundary processes influence the ocean are reviewed. In the first topic, solutions for the flow and stratification in a situation where mixing dies away slowly away from a sloping boundary can show a sensitivity to the eddy Prandtl number, emphasizing the importance of studying the mixing of momentum as well as buoyancy. In the second topic, the importance of near-bound...

This paper reports the fabrication of a bulk micromachined hybrid torsional micromirror device composed of titanium mirror structures bonded to an underlying silicon sloping electrode structure. The fabrication of the device is enabled by two recent innovations: 1) the Metal Anisotropic Reactive Ion etching with Oxidation (MARIO) Process [1], which provides, for the first time, high aspect rati...
