A novel surface modification method was investigated. The surface of siliceous materials was modified using polystyrene, poly(acrylic acid), poly(N-isopropylacrylamide), and poly(p-acrylamidophenyl-α-mannoside) synthesized by reversible addition-fragmentation chain transfer polymerization. Thiol-terminated polymers were obtained by reduction of the(More)
The increased capacity of document image retrieval systems has necessitated an efficient method for indexing parts of document images. This is particularly important for graphs, because graphs provide the relationships between two items a user is searching for. This paper proposes a method that recognizes and indexes different kinds of graphs. Coordinates(More)
A copolymer with α-D-mannose (Man) and trimethoxysilane (TMS) units was synthesized for immobilization on siliceous matrices such as a sensor cell and membrane. Immobilization of the trimethoxysilane-containing copolymer on the matrices was readily performed by incubation at high heat. The recognition of lectin by poly(Man-r-TMS) was evaluated by(More)
Matrix-assisted laser desorption/ionisation (MALDI) imaging mass spectrometry (IMS) allows for the simultaneous detection and imaging of several molecules in brain tissue. However, the detection of glycerolipids such as diacylglycerol (DAG) and triacylglycerol (TAG) in brain tissues is hindered in MALDI-IMS because of the ion suppression effect from(More)
In high power ICRF experiments on the GAMMA 10 tandem mirror, plasmas with a strong temperature anisotropy are produced when the cyclotron resonance layer exists near the midplane of the central cell. Saturation of the diamagnetism is sometimes observed when the heating ICRF power is increased. In the plasmas with the strong temperature anisotropy,(More)
Porous membranes with glycopolymer brushes were prepared as biomaterials for affinity separation. Glycopolymer brushes contained acrylic acid and D-mannose or N-acetyl-D-glucosamine, and were formed on substrates by surface-initiated atom transfer radical polymerization. The presence of glycopolymer brush was confirmed by X-ray photoelectron spectroscopy,(More)
