New thermocouple-based microwave/millimeter-wave power sensor MMIC techniques in GaAs

We describe a new RF and microwave power sensor monolithic microwave integrated circuit design. The circuit incorporates a number of advances over existing designs. These include a III–V epitaxial structure optimized for sensitivity, the figure-of-merit applicable to the optimization, a mechanism for in-built detection of load ageing and damage to extend calibration intervals, and a novel symmetrical structure to linearize the high-power end of the scale

Legumes are notable for their ability to convert atmospheric dinitrogen into forms of nitrogen which are usable by plants. This is done in association with bacteria (called Rhizobium) which inhabit nodules of the plant roots. This process is called nitrogen-fixation. Legumes are important as forage and food crops due to their high protein content. Some are also useful for soil conservation purposes. There was no information on nitrogen fixation by legume crops in Alaska. This research was initiated to determine how much nitrogen different types of legumes can fix in interior Alaska

A Chose By Any Other Name: Domain Names As a Security Interest

There has been increasing study of the issues involved in using intellectual property as a security interest, but little corresponding consideration of domain names. The ascendancy in value of domain names to modern business increases their usefulness as a security interest to lenders and borrowers alike. Their use in this respect appears not to be weighed down by two of the most difficult issues facing intellectual property, namely conflicting jurisdiction between federal statutory interests and provincial property interests, together with establishing more readily acceptable methods of valuation. However, there is ambiguity about the actual form of ownership interest involved with a domain name, which this paper addresses directly and offers an opinion on. It concludes by proposing a framework facilitating the use of domain names as security interest by engaging the active participation of domain name registrars

APPLICATIONS OF ANTIOXIDANT AND ANTI-INFLAMMATORY POLYMERS TO INHIBIT INJURY AND DISEASE

There is an undeniable link between oxidative stress, inflammation, and disease. Currently, approaches using antioxidant therapies have been largely unsuccessful due to poor delivery and bioavailability. Responding to these limitations, we have developed classes of polymer and delivery systems that can overcome the challenges of antioxidant and anti-inflammatory therapy. In our initial studies, nanoparticles of poly(trolox), a polymeric form of trolox, were surface-modified with antibodies. This modification allows for specific targeting to endothelial cells, affording controllable and localized protection against oxidative stress. We have shown these targeted nanoparticles bind, internalize, and provide protection against oxidative stress generation and cytotoxicity from iron oxide nanoparticles. In a similar fashion, we have tested the ability of poly(trolox) to prevent rheumatoid arthritis in vivo. Poly(trolox) nanoparticles were encapsulated in a PEGylated polymer to enhance circulation and biocompatibility. These particles were shown to accumulate in inflamed joint tissue, recover natural antioxidant function, suppress protein oxidation, and inhibit inflammatory markers. Lastly, we developed a class of polyphenolic compounds utilizing a non-free radical based reaction chemistry of poly(β-amino esters). The polyphenol apigenin was investigated for its anti-inflammatory properties to inhibit inflammation-mediated tumor cell metastasis. PEGylated nanoparticles that incorporated apigenin poly(β-amino ester) were developed and found to retain their anti-inflammatory efficacy while providing a long term release profile. These inhibited the ability of tumor cells to adhere to inflamed vascular cells. We also have shown that these polymers can suppress markers of inflammation responsible in enhancing tumor cell adhesion
