n engl j med 366;19 nejm.org may 10, 2012 e30 A 3-year-old girl presented with a 3-week history of low back pain. Physical examination revealed mild tenderness over the upper lumbar spine. Lateral radiographs showed a moderate collapse of the first lumbar vertebra (Panel A, arrow). The results of a complete blood count, complete metabolic profile, and(More)
This paper proposes a novel reversible data hiding scheme based on a Vector Quantization (VQ) codebook. The proposed scheme uses the principle component analysis (PCA) algorithm to sort the codebook and to find two similar codewords of an image block. According to the secret to be embedded and the difference between those two similar codewords, the original(More)
In this study, advanced control of crystallographic orientations and magnetic properties of self-assembled nanostructures via rational selections of substrates is demonstrated. We show that in the perovskite-spinel BiFeO(3)-CoFe(2)O(4) model system the crystal orientation of self-assembled CoFe(2)O(4) nanopillars can be tuned among (001), (011), and (111),(More)
BACKGROUND & AIMS The serrated pathway is a distinct pathway of colorectal carcinogenesis that has been implicated in development of a substantial proportion of interval colorectal cancers. The fecal immunochemical test (FIT) detects early neoplasms with a higher level of sensitivity than the guaiac test. We investigated the sensitivity of the FIT in(More)
We report a case of giant cell tumor occurring in a 12-year-old girl. Radiographs revealed a radiolucent lesion in the proximal epi-metaphysis of the right fibula, which was initially diagnosed as an aneurysmal bone cyst. Magnetic resonance imaging showed an expansile intramedullary lesion with focal multiloculated fluid-fluid levels and also solid mass in(More)
With the rise and development of information technology (IT) services, the amount of data generated is rapidly increasing. Data from many different places are inconsistent. Data capture, storage and analysis have major challenges. Most data analysis methods are unable to handle such large amounts of data. Many studies employ neural networks, mostly(More)

Hospice palliative care for terminal patients is necessary, yet challenges are on the way worldwide. This study demonstrated that hospice palliative care has been quickly developed in Taiwan due to the support of the National Health Insurance system, the promotion by civil societies and religious groups, patient's legal right for DNR, easier access to pain(More)
