Abstract: An image forming apparatus includes a registration unit, a first paper feeding unit, a second paper feeding unit, and a control unit, which performs a primary paper feeding for conveying a paper sheet to a registration position, finishes the primary paper feeding at timing when the paper sheet reaches the registration position, and then after operating a target paper feeding unit until a preceding feeding time elapses, performs a secondary paper feeding for conveying the paper sheet to the printing position. The control unit sets different values of the preceding feeding time for the case where the first paper feeding unit is the target paper feeding unit and the case where the second paper feeding unit is the target paper feeding unit.

Abstract: An image forming apparatus that includes: an image reading portion capable of reading image data of the document sheet; document sheet detection sensors; an ADF including a document holding surface on which first and second areas having different reflection characteristics and third and fourth areas having different reflection characteristics are formed; a first reading control portion that causes the image reading portion to read image data of both the first and second areas when the ADF is closed; a first document sheet width detection portion that detects a width of the document sheet based on the image data read from the first area or the image data read from the second area; and a first size detection portion capable of detecting the size of the document sheet based on detection results from the first document sheet width detection portion and the document sheet detection sensors.

Abstract: The pickup roller is placed above a lifting plate made of a flexible material and feeds the sheet with abutting on an upper surface of the sheets loaded on the lifting plate. The sensor detects an arrival of the sheet fed by the pickup roller on a downstream side of the pickup roller. The abnormality detection unit detects the sheet feeding abnormality of the sheet fed by the pickup roller based on the drive start time of the pickup roller and the time sheet detection by the sensor. The abnormality detecting condition correction unit corrects the abnormality detecting condition of the abnormality detection unit depending on the amount of sheets on the lifting plate.

Abstract: Biomarkers for diagnosis and prognosis of prostate cancer are provided. The biomarkers are promoter sequences have altered methylation patterns relative to normal prostate tissue. Altered expression of DNA methyltransferases (DNMT) and proteins that interact with DNMT result in increased methylation at a subset of prostate tumor hypermethylation sites.
