Cold tolerance at the seedling stage of rice is an important phenotypic trait that causes normal plant growth and stable rice production in temperate regions as well as tropical high-lands in Asia and Africa. In order to find quantitative trait loci (QTLs)/genes associated with cold tolerance, we constructed a linkage map using 153 recombinant inbred lines(More)
The design and performance of a wideband power amplifier MMIC suitable for electronic warfare (EW) systems and other wide bandwidth applications is presented. The amplifier utilizes dual field plate 0.25-mum GaN on SiC device technology integrated into the three metal interconnect (3MI) process flow. Experimental results for the MMIC at 30V power supply(More)
The lifetime prevalences of DSM-III mental disorders using Korean version of DIS-III are presented. They were studied in 5,100 adults (aged 18 to 65) in household selected by two stage cluster sampling. Comparisons were made between regions, sex and age groups. International comparison with Epidemiologic Catchment Area program was also made.
This work presents a systematic study of millimetre-wave, low-noise, widely-tuneable differential Colpitts VCOs. A design methodology was developed and validated experimentally over thirteen different varactor-tuned (VCO) and fixed-frequency L-C oscillators spanning the 30-GHz to 122-GHz frequency range. All circuits employ accumulation-mode n-MOS(More)
This paper proposes new field functions that have adjustable inner radius and outer radius of influence. Incorporating the proposed field functions with soft object modeling, soft blending, Ricci's super-ellipsoid blends, Perlin's set operations, and R-functions, etc. can have blending range controls by adjusting the inner and the outer radii of influence(More)
This paper presents a scale method for developing high dimensional scale functions to blend implicitly defined objects. Scale functions are differentiable on the entire domain except the origin, provide blending range control, and behave like Min/Max operators everywhere, so even a successive composition of blending operations containing overlapped blending(More)
