We report on the first results obtained with a novel silica based optical beam former. It is a key device for smart antenna environments. The device was tested in an experimental 60 GHz transmission system using optical millimeter-wave generation and

A widely applicable promoter system is described that allows a gene of interest to be activated in specific plant tissues after a cross between defined transgenic lines. The promoter, pOp, consists of lac operators cloned upstream of a minimal promot

A concept is proposed for a pico-cellular network for broad-band mobile communication on a millimeter-wave basis. How microwave optical-signal-processing techniques based on mode-locked lasers (MLLs), optical modulators, and high-speed photo diodes (

Fiber loop optical buffers enable data storage for discrete time intervals and therefore appear suitable for applications in optical asynchronous transfer mode (OATM)-based networks where data are transmitted in cells of fixed length. In this paper,

Experiments are described using a photonic beam former to control a 60-GHz smart antenna. The 60-GHz signals are generated by optical heterodyning the waves of two laser diodes. Beam forming is achieved by new photonic planar lightwave circuits in si

Plant cells have an acute sense for pathogen-derived chemical stimuli, so-called elicitors, which induce the plant's defense response. To investigate the molecular basis of chemosensory transduction, elicitor-treated tomato cells were labeled with 1-

Summary An elicitor preparation consisting of glycopeptides partially purified from yeast extract and the membrane- perturbing agents chitosan and digitonin were compared with respect to their effects on ethylene biosynthesis, phenylalanine ammonia-l

The induction of ethylene biosynthesis by an elicitor partially purified from yeast extract was studied in suspension-cultured tomato (Lycopersicon esculentum Mill.) cells. Unstimulated cells produced little ethylene during exponential growth and eve
