—The quantitative performance indicators of Physical Unclonable Functions (PUFs)—Randomness, Steadiness, Correctness, Diffuseness and Uniqueness—are strictly defined and applied to the evaluation of 45 arbiter PUFs on Virtex-5 FPGAs. The indicators effectively reflect the characteristics of PUFs ranging from 0 to 1 with 1 being the highest performance. The(More)
This paper examines numerical algorithms for factoriza-tion of a low-rank matrix with missing components. We first propose a new method that incorporates a damping factor into the Wiberg method to solve the problem. The new method is characterized by the way it constrains the ambiguity of the matrix factorization, which helps improve both the global(More)
Purpose. Docetaxel/5-FU/CDDP (DFP) therapy is a useful treatment for advanced esophageal cancer. However, adverse reactions such as chemotherapy-induced nausea and vomiting (CINV) interfere often with continuation of the chemotherapy. We investigated the efficacy of rikkunshito (TJ-43) on CINV. Methods. Nineteen patients who were going to undergo DFP(More)
PURPOSE Extracellular matrix metalloproteinase inducer (EMMPRIN) has been reported to play crucial roles, including in angiogenesis, in several carcinomas. However, the correlation between EMMPRIN levels and angiogenesis expression profile has not been reported, and the role of EMMPRIN in renal cell carcinoma (RCC) is unclear. In the present study, we(More)
absTracT It is desirable to build up a lecture video library to enable students to view past lectures at any time and from anywhere on their PCs. For this purpose, we developed a lecture video player/maker system (Yoshida, 2002, 2003). In developing this system, we considered the usability for students and oper-ability for teachers. The player includes a(More)
Recently, not only still pictures but also moving pictures are displayed on the PDAs or cellular phones. When we take a look such pictures, the picture quality seems to be better than those on the CRTs or the large LCDs. In order to clarify the reason, we have investigated the relationship between the subjective quality of different size of pictures with(More)
Although the dissemination of urothelial cancer cells is supposed to be a major cause of the multicentricity of urothelial tumors, the mechanism of implantation has not been well investigated. Here, we found that cancer cell clusters from the urine of patients with urothelial cancer retain the ability to survive, grow, and adhere. By using cell lines and(More)
Non-muscle invasive bladder cancer is treated with intravesical chemotherapy (IVC) after transurethral resection (TUR) to reduce the probability of recurrence. Despite improvement, the recurrence rate remains high. Intravesical chemotherapeutics at high doses are expected to ablate unresected tumors and floating cancer cells after TUR, although the fate of(More)
Japanese species of the genus Psammoecus Latreille, 1829 are taxonomically revised. Four new species, P. scitus sp. n. (misidentified with P. quadrimaculatus), P. labyrinthicus sp. n., P. boreas sp. n. and P. omotoensis sp. n. are described. Psammoecus bipunctatus (Fabricius, 1792), P. trimaculatus Motschulsky, 1858 (misidentified with P. triguttatus), P.(More)
