We test whether the complexity of the cardiac interbeat interval time series is simply a consequence of the wide range of scales characterizing human behavior, especially physical activity, by analyzing data taken from healthy adult subjects under three conditions with controls: (i) a "constant routine" protocol where physical activity and postural changes(More)
This paper presents a jazz session system in which each player is independent and can interplay with all other players. In most previous systems, computer players only reacted to human player's performance with a fixed leader-follower relationship. Our system enables computer players to listen to other computer players' performances as well as human's(More)
Mechanical and chemical sensitivity of the palatine nerve, ramus palatinus facialis, innervating the anterior palate of the puffer, Fugu pardalis, and their central projection to the primary taste center were investigated. Application of horseradish peroxidase (HRP) to the central cut end of the palatine nerve resulted in retrogradely labeled neurons in the(More)
By injecting noise into the carotid sinus baroreceptors, we previously showed that heart rate (HR) responses to weak oscillatory tilt were enhanced via a mechanism known as "stochastic resonance." It remains unclear, however, whether the same responses would be observed when using oscillatory lower body negative pressure (LBNP), which would unload the(More)
Electrophysiological recordings were obtained from two branches of the facial nerve innervating oral and extra-oral taste receptive fields, respectively, in the channel catfish, Ictalurus punctatus. The results indicate that taste buds innervated by the ramus ophthalmicus superficialis (ros), innervating taste buds on the nasal barbel, and the ramus(More)
This paper presents an automatic accompaniment system for jazz that understands solist's intention of improvising and outputs expressive accompaniment of a bass guitar and drums reacting to solo. Previous systems extracted just one parameter as solist's intention and output accompaniment by switching registered patterns. Our system can understand solist's(More)
BACKGROUND & AIMS Hepatic arterial infusion chemotherapy (HAIC) is an option for treating advanced hepatocellular carcinoma (HCC). Because of the poor prognosis in HAIC non-responders, it is important to identify patients who may benefit from continuous HAIC treatment; however, there are currently no therapeutic assessment scores for this identification.(More)
