Inflammation and oxidative stress are important factors in the pathogenesis of diabetes and contribute to the pathogenesis of diabetic complications. Periodontitis is an inflammatory disease that is characterized by increased oxidative stress, and th

Cimetidine is a powerful H2 receptor antagonist that eliminates histamine's effects on chemotaxis, phagocytosis, and superoxide anion production by phagocytes. The purpose of this study was to analyze the clinical and histopathological changes associ

In this paper, we discuss the applications and also several important system issues: insertion loss, noise figure, dynamic range and cost relating to photonics for wideband phased array antennas. This discussion is based on the work that we did on an

We report the demonstration of a 4-bit optoelectronic-switched silica-waveguide time-delay network. Targeted for insertion into a 96-element L-band conformal array, the optical time- shifter provides 16 programmable time-delays in steps of 0.248 nsec

We have fabricated a > 10 GHz high speed optoelectronic (OE), selector switch with high isolation (> 57 dB). This switch was used as a receiver for a microwave network demonstration with simulated satellite feeds of FM video and microwave BPSK digita

Presented in this paper is an overview of the development of a wideband photonic array antenna. The presentation will focus on the performance of a unique L-band 24 X 4 element conformal array, supported by a photonic true-time-delay beamforming netw

Subcarrier-multiplexed (SCM) optical links combine high-speed digital and analog signals onto an optical carrier.1 Figure 1 shows how multiple antenna feeds could be distributed over a wavelength-division-multiplex (WDM) based system. At each port an

It is well known that a key element in advanced photonic system architectures are arrays of sources and detectors. For example, such devices are useful in optoelectronic switching matrices,1 byte-wide communication, and active wavelength division mul

The effects of various sugars and sugar derivatives on lung colonization (i.e., metastatic deposition) of the highly metastatic BL6 clone of B16 mouse melanoma cells in syngeneic mice were studied, based on the assumption that carbohydrate structures
