A new strategy of stepwise surface regeneration for electrochemical immunosensors, working on a biocatalyzed precipitation reaction, has been developed. The strategy is based on the combination of deposited product thin-film dissolution and bound-protein displacement reactions from the modified sensor surfaces. As a model system, surfaces functionalized with biotin groups and their affinity rec...

To refine the early Middle Miocene (ca. 16 Ma) paleomagnetic direction in the Motegi area, we collected paleomagnetic samples from dacite domes and intrusives of the Motegi Formation. Characteristic remanent magnetization components were revealed by stepwise demagnetization, which were used to calculate site-mean directions for 10 sites. Together with published data from 11 andesite and basalt ...

A theoretical model of the EOF established in a wide capillary after the application of a stepwise voltage has been developed. Both periodical and aperiodical flow regimes were studied with arbitrary pulse/pulse or pulse/pause durations and amplitudes. The numerical analysis performed for a few types of periodical regimes showed the peculiarities of the profiles of liquid velocity and its displ...

Two novel devices, torsional actuator and torsional stepper motor, are described and their performance is investigated in detail. Both devices were designed to produce large angular displacement and large torque output from the piezoelectric d15 shear response. In the torsional actuator, the large displacement can be achieved due to built-in amplification of piezoelectric strain using the aspec...

A theoretical model of the EOF and hydrodynamic flow in wide closed cylindrical capillaries, after the application of a stepwise voltage, is developed. Analytical expressions have been obtained as a sum of the solutions for the direct flow and backflow in both periodical and aperiodical regimes with arbitrary pulse/pulse or pulse/pause durations and amplitudes. The numerical analysis, performed...

This paper describes a robust control design for automatic steering of passenger cars. Previous studies 1, 2] showed that reliable automatic driving at highway speed may not be achieved under practical conditions with look-down reference systems which use only one sensor at the front bumper to measure the lateral displacement of the vehicle from the lane reference. An additional lateral displac...
