Dual subwavelength Ag gratings with a small gap of about 15 nm are demonstrated to provide a huge additional SERS enhancement, more than 10(3) fold in scattering efficiency over normal SERS on an Ag film due to the strong plasmon coupling, which is simulated by theoretical calculation. The simulation also shows the advantages of the coupled two-layer gratings over the one-layer grating for SERS...

The myocardium takes up two major substrates: glucose and fatty acids, and various methods have been used to evaluate this uptake. Despite extensive study of radiotracer uptake-based methods, however, an easily applicable datasheet has not previously been provided. In this manuscript, an example of a method involving an easily modified data sheet based on dual tracer methods is presented. This ...

We describe here an experimental approach designed to aid in the identification of complex brain circuits within the rat corpus striatum. Our aim was to characterize in a single section (i) striatal thalamic afferents, (ii) striatopallidal projection neurons and (iii) striatal local circuit interneurons. To this end, we have combined anterograde tracing using biotinylated dextran amine and retr...

This article addresses the computation of invariant and stabilizing control laws for dual-substrate fed-batch fermentors. The design is based on two commonly used model structures. It will be shown how to derive partial state feedbacks, using only biomass and volume as measures, that keep the substrates at a desired concentration provided the model is good enough and does not change with time. ...

We report results from a highly versatile and scalable raster-scanned continuous wave CO2 laser heater incorporating a dual wavelength photodiode-based temperature monitoring system with feedback control. The system is able to uniformly heat substrates inside a vacuum chamber, reduce the occurrence of substrate fracture and allow almost negligible heat loss to the deposition chamber and surroun...

New configurations of compact dual/triple/ multiple pass-band filters, which are well suited for applications in wireless communications, are presented. Asymmetric stepimpedance resonators are the main elements for the design of these filters. In order to increase the number of attenuation poles in the vicinity of the pass-band regions, negative and positive cross coupling between source and lo...

Biaxial tensile strained Si grown on SiGe virtual substrates will be incorporated into future generations of CMOS technology due to the lack of performance increase with scaling. Compressively strained Ge-rich alloys with high hole mobilities can also be grown on relaxed SiGe. We review progress in strained Si and dual channel heterostructures, and also introduce high hole mobility digital allo...

The aim of this work was to develop a new bifunctional maleimide linker for the development of dual-acting prodrugs that incorporate two pharmaceutically different anticancer agents independently bound by enzymatically cleavable substrates. The linker consists of a carboxyl group in one arm and an activated 1,6-self-immolative para-aminobenzyloxycarbonyl spacer together with a cathepsin B cleav...

At 25.0 °C the specific rates of solvolysis for allyl and vinyl chloroformates have been determined in a wide mix of pure and aqueous organic mixtures. In all the solvents studied, vinyl chloroformate was found to react significantly faster than allyl chloroformate. Multiple correlation analyses of these rates are completed using the extended (two-term) Grunwald-Winstein equation with incorpora...
