    Abstract: A breast carcinoma tyrosine phosphoprotein, DDR (Discoidin Domain Receptor), that defines a novel class of receptor tyrosine kinases is presented. The DDR cDNA predicts a polypeptide C-terminal tyrosine kinase domain and an N-terminal domain similar to the Dictyostelium discoideum lectin discoidin I. These domains are connected by an extraordinary hydrophilic proline/glycine-rich domain, which is interrupted by a predicted transmembrane sequence. This extended proline/glycine-rich region suggests an unusual geometry of interaction with ligand or substrates. Discoidin I-type domains may interact with specific cell surface molecules.

    Abstract: A water purification device, method and system with the water purification device having a container for holding a water purification material therein with the water purification device including a shroud extending in a direction generally normal to a flow of debris laden water with the shroud inhibiting direct flow of debris into a water inlet in the water purification device by directing water and debris over the shroud and around the water purification device while a portion of the water can be directed laterally into the water purification material within the water purification device to thereby purify the water that flows over the water purification materials with the water purification device including multiple spaced and positioned water inlets so that the likelihood of the water inlet being completely obstructed is remote.

    Abstract: A digital-to-analog converter includes a resistive divider network including a plurality of series resistors of resistance R and a plurality of shunt resistors of resistance 2R' and a circuit for switching a shunt resistor of the resistive divider network in the digital-to-analog converter to either of first and second reference voltages. The switching circuit includes a first switch MOSFET coupling the low reference voltage to the shunt resistor, and a second switch MOSFET coupling the shunt resistor to the high reference voltage. First and second switch control circuits adjust the on resistances of the first and second switch MOSFETs to be proportional to the resistances of first and second reference resistors, which have the same temperature coefficient as the resistors of which the divider network is composed. The on resistance of each of the first and second switch MOSFETs is equal to R.sub.ONi, and the resistance 2R' is equal to 2R-R.sub.ONi. The on resistances do not need to be binarily scaled.
