Because of the redundancy factors of FPGAs, there is a performance gap between FPGAs and ASICs. In this paper, we propose a small-memory logic cell, COGRE, to minimize the FPGA area. Our approach is to investigate the appearance ratio of the logic functions in a circuit implementation. Moreover, we group the logic functions on the basis of the(More)
An important pathway of gene transcriptional inactivation is hypermethylation at the CpG islands of promoter regions. Some tumor suppressor genes have been reported to harbor promoter hypermethylation in head and neck cancer. We studied DNA hypermethylation of 4 genes in 42 cases of primary head and neck cancer. We applied methylation specific PCR for p16,(More)
The aim of the present study using near-infrared spectroscopy (NIRS) is to evaluate the correlation of cerebral (parieto-temporal lobe) hemoglobin changes and vertiginous sensation during unilateral caloric stimulation. During the hot water (44 degrees C) stimulus, cerebral hemoglobin was increased bilaterally, but it was dominant ipsilaterally. During the(More)
BACKGROUND The objective of this study was to evaluate the efficacy and safety of minimally invasive transoral en bloc resection of superficial pharyngeal and laryngeal cancers. METHODS Forty-one superficial lesions (from 35 patients) were resected transorally under a surgical microscope using a monopolar cautery. Quality of life (QOL) was assessed using(More)
OBJECTIVES To evaluate the antitumor effect of the coincident administration of intravesical gemcitabine (Gem) plus bacillus Calmette-Guérin (BCG) in an orthotopic bladder cancer model. METHODS We evaluated the cytotoxic effect of gemcitabine against MBT-2 cells in vitro. Orthotopic tumors were established by implanting MBT-2 cells into the bladder of(More)
Silicone was one of the most common biocompatible materials used for orbital floor reconstruction about twenty to thirty years ago. Recently, surgeons hardly use silicone due to numerous reports of complications such as infection, extrusion and implant displacement. We present a case of chronic infection seen after 28 years of silicone implant used in(More)
SRAM-based field programmable gate arrays (FPGAs) are vulnerable to a single event upset (SEU), which is induced by radiation effect. This paper presents a technique for ensuring reliable softcore processor implementation on SRAM-based FPGAs. Although an FPGA is susceptible to SEUs, these faults can be corrected as a result of its reconfigurability. We(More)
Generally, a programmable LSI such as an FPGA is difficult to test as compared to an ASIC. There are two major reasons for this. One is that automatic test pattern generator (ATPG) cannot be used because of the programmability of the FPGA. The other reason is that the FPGA architecture is very complex. In this paper, we propose a novel FPGA architecture(More)
