The biological actions of heparin and heparan sulfate, two structurally related glycosaminoglycans, depend on the organization of the complex heparanome. Due to the structural complexity of the heparanome, the sequence of variably sulfonated uronic acid and glucosamine residues is usually characterized by the analysis of smaller oligosaccharide and disaccharide fragments. Even characterization of...
Contention resolution and forwarding of labeled optical packets at 40 Gb/s is demonstrated utilizing multiple InP based optical buffers and monolithic wavelength converters. Layer-2 packet recovery measurements are presented.
We demonstrate a single-chip 40 Gb/s wavelength converter based on an SG-DBR laser and field-modulated optical gate. This device also performs 10 Gb/s label encoding for all-optical packet forwarding.
Millimetre wave transmittance measurements of common materials have been performed from 30 to 120 GHz. A free space quasi-optical millimetre wave spectrometer, equipped with a set of high power sources of tuneable coherent radiation has been successfully applied. Frequency dependences of real and imaginary parts of the dielectric permittivity have been obtained in a broad-band millimetre wave frequency...
Millimeter-wave transmittance measurements of common household powdered materials over the frequency range spanning from 35 GHz to 120 GHz. Frequency dependences of real and imaginary parts of the dielectric permittivity have been calculated from the transmittance spectra. This wide band spectroscopy makes use of a backward wave oscillator as a high power tunable source of radiation which is preferable...
A dielectric study of new glass specimens is reported using free-space quasi-optical spectroscopy over a frequency range spanning from 40 GHz to 120 GHz. This wide band spectroscopy makes use of a backward wave oscillator as a high power tunable source of radiation. It enables the achievement of relatively higher output power compared to other non-contact techniques. It is more preferable for the...
