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)
Introduction: The detection of tissue borders is of great importance in several MRI applications. Edge detection is typically performed as a post-processing step, using magnitude images that are reconstructed from fully-sampled k-space data. In dynamic imaging (e.g. of human speech, ventricular function, and joint kinematics), tissue borders often comprise(More)
For the intertidal copepod Tigriopus californicus, outbreeding depression for a variety of fitness measures is typically observed in early-generation interpopulation hybrids. We examined both controlled crosses and long-term, freely mating experimental hybrid swarms composed of individuals from Baja California (Mexico) populations Playa Altamira and Punta(More)
Introduction: Variable density spiral (VDS) imaging typically samples low spatial frequencies densely and high spatial frequencies sparsely [1]. Reconstructed images are prone to aliasing artifacts, but they are considered to be acceptable in certain cases where aliasing of high spatial frequencies do not significantly deteriorate image quality. VDS imaging(More)
Illustration of the slice-interleaf order. Slice 1 and 2 are denoted by yellow and gray colors, respectively. The spiral interleaf index is indicated by the number within each block. This shows 4-interleaf case, and 13-interleaf spiral was used in the in-vivo experiments. (a) Temporal ordering of the slice and spiral interleaf. Sliding window reconstruction(More)
To estimate the prevalence of urinary stone disease in Koreans, and to determine the inter-relationships between urinary stone disease and various epidemiological factors, 1,521 controls and 1,177 cases with urinary stones were evaluated. Of special interest in this study were: 1) proportion of past urinary stone history among controls; 1.9% 2) the point(More)
We describe a case of solitary myeloma showing cystic change filled with massive crystalline structures in a 54-year-old woman. A bone X-ray showed a solitary cystic osteolytic lesion in the right iliac bone. Serum and urine protein electrophoresis showed no demonstrable M-protein, and bone-marrow aspirates did not show any myeloma cells. Histologic(More)
OBJECTIVES Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors(More)
