A relatively liberal response bias for high-frequency words and a violation of the mirror effect for hit and false-alarm rates were found in a yes-no recognition-memory test. Subjects more frequently responded "old" to high-frequency words than to low-frequency words. Four experiments were conducted to determine the causes of the different response biases(More)
Bradyrhizobium sp. S23321 is an oligotrophic bacterium isolated from paddy field soil. Although S23321 is phylogenetically close to Bradyrhizobium japonicum USDA110, a legume symbiont, it is unable to induce root nodules in siratro, a legume often used for testing Nod factor-dependent nodulation. The genome of S23321 is a single circular chromosome,(More)
Upper airway obstruction during sleep can trigger compensatory neuromuscular responses and/or prolong inspiration in order to maintain adequate minute ventilation. The aim of this study was to investigate the strength of these compensatory responses during upper airway obstruction during propofol anesthesia. We assessed respiratory timing and upper airway(More)
In recent years it becomes possible to download comic strips and read them on cell phones. Japanese companies such as SONY have started to deliver digitalized comic strips to cell phone users. The market is attractive and promising since cartoons are popular in Japan across generations, while there are plenty of the well-drawn/well-written classical comic(More)
Ammonia monooxygenase subunit A gene (amoA) is frequently used as a functional gene marker for diversity analysis of ammonia-oxidizing bacteria (AOB). To select a suitable amoA primer for real-time PCR and PCR-denaturing gradient gel electrophoresis (DGGE), three reverse primers (degenerate primer amoA-2R; non-degenerate primers amoA-2R-GG and amoA-2IR)(More)
Agricultural soil is the largest source of nitrous oxide (N2O), a greenhouse gas. Soybean is an important leguminous crop worldwide. Soybean hosts symbiotic nitrogen-fixing soil bacteria (rhizobia) in root nodules. In soybean ecosystems, N2O emissions often increase during decomposition of the root nodules. Our previous study showed that N2O reductase can(More)
BACKGROUND Many of the posttraumatic stress disorder (PTSD) treatment guidelines recognize the use of selective serotonin reuptake inhibitors as first-line pharmacological treatment. In Japan, there were no published studies investigating the effectiveness and safety of sertraline for PTSD in a clinical setting. METHODS We conducted a retrospective(More)
Twitter has grown so rapidly that its users are suffering from an information ove rload. In order to help people to find interesting tweets and users from the enormous Twitter space, by applying the document similarity of Gerard Salton and Christopher Buckley to Twitter streaming data, we attempt to devise a content-based scheme that compares similarities(More)
