An apparatus and a method for processing checks and other negotiable instruments efficiently captures MICR data required for electronic payment and an image of the check or negotiable instrument enabling the amount, payee, and other information printed or written on the check face to be clearly read. The image reading unit 11 of the check processing apparatus 110 scans and outputs a gray scale image of the check. A threshold value determination unit 12 sets a threshold value for digitizing the image data based on the density level frequency distribution of primary gray scale image data obtained by the image data reading unit scanning a first scanning area T. This first scanning area contains part of a printed text area 127 where text is printed on the negotiable instrument and part of the background 49 of the negotiable instrument. A digital image processor 20 digitizes and converts secondary gray scale image data to digital image data based on the threshold value set by the threshold value determination unit 12. The secondary gray scale image data is generated by the image reading unit 11 scanning a predefined second scanning area of the negotiable instrument.

The present invention provides compositions and methods for the production of differentiated mammalian cells. More particularly, the present invention provides cellular differentiation methods employing culturing the cells on a feeder layer or under feeder-free conditions in cell culture and further contacting the cells with an inhibitor of the PI3-kinase pathway and a member of the TGFb family for the generation of differentiated mammalian cells from pluripotent mammalian stem cells. Preferably, the differentiated cell is selected from the group consisting of a mesendodermal cell, a mesodermal cell, and an endodermal cell.

A method and apparatus are disclosed for generating a rating scale to be used in an evaluation form, the rating scale comprising a plurality of rating levels, each comprising at least one element to rate and a plurality of qualifying quantifiers, associating at least one of the qualifying quantifiers to each of the elements to rate.

A method of ex-vivo expanding a population of stem cells, while at the same time inhibiting differentiation of the stem cells. The method comprises ex-vivo providing the stem cells with conditions for cell proliferation and with at least one copper chelator in an amount and for a time period for permitting the stem cells to proliferate and, at the same time, for reducing a capacity of the stem cells to differentiate

For realizing high speed flash memory, bit line is multi-divided for reducing parasitic capacitance, so that local bit line is quickly discharged when reading a memory cell and multi-stage sense amps are used, wherein the multi-stage sense amps are composed of a first dynamic circuit serving as a local sense amp connecting to the local bit line through a read transistor, a second dynamic circuit serving as a segment sense amp for reading the local sense amp, and a tri-state inverter serving as an amplify circuit of a global sense amp for reading the segment sense amp. When reading data, a cell current difference is converted to a time difference for differentiating low threshold data and high threshold data by the multi-stage sense amps. And a buffered data path is connected to the global sense amp for achieving fast data transfer. Additionally, alternative circuits and memory cell structures are described.
