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)
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)
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)
Current commercial SRAM-based FPGAs, such as Virtex-6 and Stratix-V, can perform dynamic partial reconfiguration (DPR). Partial reconfiguration (PR) can change a part of the device without reconfiguring the whole chip. Thus, we can switch the part of system with continuing the operation. However, the authorized design flow by Xilinx creates different PR bit(More)
The authors examined the association between white blood cell (WBC) count and the development of gastric cancer in a 19-year follow-up study of 2,558 Japanese subjects aged ≥40 years (1988-2007). The subjects were stratified into 4 groups according to baseline WBC quartile (≤4.4, 4.5-5.2, 5.3-6.3, or ≥6.4 × 10(3) cells/μL). During follow-up, 128 subjects(More)
OBJECTIVE To overcome very few facilities available for polysomnography, a portable device of polygraphy was introduced into home monitoring for the assessment of obstructive sleep apnea syndrome (OSAS) in children. METHODS Forty-eight children (aged 2-11) presenting with snoring and sleep apnea were subjected to home monitoring. Sleeptester™ (Fukuda(More)
A 37-year-old man with juvenile and refractory hypertension was admitted to our hospital for progressive left hearing loss, vertigo, and dizziness. Neurological examination revealed left hearing loss and exaggerated deep tendon reflexes and vestibular dysfunction. MRI and cerebral angiography disclosed megadolichobasilar artery (MDBA). Moreover, modified MR(More)
