For low-noise complementary metal-oxide-semiconductor (CMOS) image sensors, the reduction of pixel source follower noises is becoming very important. Column-parallel high-gain readout circuits are useful for low-noise CMOS image sensors. This paper presents column-parallel high-gain signal readout circuits, correlated multiple sampling (CMS) circuits and(More)

Logarithmic cameras have the wide dynamic range required to image natural scenes and encode the important contrast information within the scene. However, the images from these cameras are severely degraded by fixed pattern noise. Previous attempts to improve the quality of images from these cameras by removing additive fixed pattern noise have lead to(More)
Noise reduction effects of column-parallel correlated multiple-sampling (CMS) for CMOS image sensors are investigated. In the CMS, the gain of the noise cancelling can be flexibly changed by the sampling number. It has a similar effect to that of amplified CDS for thermal noise but is more effective for 1/f and random telegraph signal (RTS) noises. The(More)
Since April 2011, a dosage adjustment program has been implemented at Gifu Municipal Hospital. In this program, upon receiving a prescription for renally eliminated drugs, pharmacists verify patients' serum creatinine concentrations by using a computerized medical record system to evaluate the patient's kidney function and suggest the appropriate dosage to(More)
Soybean cyst nematode (Heterodera glycines; SCN) is becoming a serious problem in azuki bean (Vigna angularis var. angularis) production in Hokkaido, Japan. To find sources of resistance to SCN, we screened wild relatives of azuki bean and calculated “female indices” (FIs) of 342 accessions from 8 Vigna species that are cross-compatible with azuki bean.(More)
We characterized a spontaneous dwarf mutant showing extremely short internodes and dark green leaves originating from azuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) cultivar "Erimo-shouzu." F(1) plants of 3 cross combinations between the dwarf mutant and several representative wild-type plants, Erimo-shouzu, V. angularis accession Acc2265 and wild(More)
