The electric-field induced absorption changes (Stark effect) of reconstituted light-harvesting complex II (LHCII) in different oligomerisation states-monomers and trimers-with different xanthophyll content have been probed at 77 K. The Stark spectra of the reconstituted control samples, containing the xanthophylls lutein and neoxanthin, are very similar to previously reported spectra of native ...

In this paper we study the resource requirements of electrooptical organizations in performing digital computing tasks. We define a generic model of parallel computation using optical interconnects, called the optical model of computation (OMC). In this model, computation is performed in digital electronics and communication is performed using free space optics. Using this model we derive relat...

Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...

We propose a theoretical analysis of the stochastic dynamics miniature optoelectronic oscillators (OEOs) based on whispering-gallery mode resonators. The core element in this microwave photonic oscillator is high-Q resonator with quadratic nonlinearity, which simultaneously performs electrooptical modulation, frequency filtering and energy storage. This multi-task allows to feature improved siz...

Space applications require image sensors that are tolerant to the harsh radiation conditions outside the earth’s atmosphere. This paper reports about an ongoing optimization experiment for radiation tolerant 4T pixels. The experiment is conducted in a 0.18μm CMOS image sensor process and involves optimization of both the layout and the process technology. The purpose of the experiment is to min...

The objective of this project is to develop methods to incrementally model and detect changes in the shape or surface material properties of terrain. The model will be derived from range data (such as interferometric synthetic aperture radar (IFSAR) elevation data) and electrooptical (EO) and infrared (IR) imagery. The imagery can be either still images or video data, such as that obtained from...

In this paper biophysical bases and frontiers of complementary medicine are considered, and essential significance of its resonance microwave (MW)/ultralowfrequency (ULF) electromagnetic (EM)/ionic nature as well as the quantum-holographic "electrooptical" neural-network-like-function of the acupuncture system are pointed out, as supported by microwave resonance therapy (MRT) of the psychosomat...
