A simple procedure for the voltammetric detection of antioxidative activity of plant extracts based on the protection from DNA damage at the electrode surface is reported. A disposable electrochemical DNA biosensor fabricated as a carbon-based screen-printed electrode modified by a surface layer of the calf thymus double stranded (ds) DNA was used as a working electrode in combination with a si...

The paper discusses the anomalies of the former interpretation of the working mechanism of the ion-selective electrodes. It was thorougly discussed why the Donnan experiment could not be applied as the theoretical background of glass electrodes. It was assumed according to the Donnan interpretation that the measurable potential is produced by the transfer of the primary ion through the membrane...

Comparison of 4×1 SIMO and 2×2 MIMO sensors based on measured propagation channels

High-speed transmission technologies using array signal processing such as Single Input Multiple Output/ Multiple Input Multiple Output (SIMO/MIMO) have been recently attracted much attention due to smart phones and wireless LAN systems. High data transmission can be realized by utilizing accurate channel state information (CSI). However, it is well known that the characteristic of SIMO/MIMO pe...

PULSE - BASED 2 D MOTION SENSORS 1 Pulse - Based 2 D Motion

| We present two compact CMOS integrated circuits for computing the 2D local direction of motion of an image focused directly onto the chip. These circuits incorporate onboard photoreceptors and focal plane motion processing. With fully functional 14 13 and 12 13 implementations consuming less than 50 W per pixel, we conclude that practical pixel resolutions of at least 64 64 are easily achieva...
