T RADITIONALLY, reciprocal rhythms have been classified as atrial and ventricular on the basis of the site to which the impulse returns.1) While the ventricular reciprocal rhythm is not uncommon, the atrial rhythm is exceedingly rare, clinically.2) We experienced an example of atrial reciprocal rhythm following electrical conversion for atrial flutter. To our knowledge, no case of atrial recipr...

Chlamydomonas reinhardtii expresses a well-documented circadian rhythm of phototaxis, which peaks in the subjective daytime. We find that vegetative cells also express circadian rhythms of chemotaxis to ammonium and ammonium uptake (as gauged by uptake of [(14)C]methylammonium). The chemotaxis rhythm peaks in the subjective night. Methylammonium uptake is light dependent, and its rhythm peaks a...

Abstract Introduction: Survival after cardiac arrest is one of the most important issues related to the safety and quality of patient care, and unexpected events such as failure to follow guidelines can endanger the patient's safety. Objective: This study aimed to determine the long-term survival after cardiopulmonary resuscitation and its predictors in patients with cardiac arrest. Materi...

A fundamental problem in music is to classify songs according to their rhythm. A rhythm is represented by a sequence of “Quick” (Q) and “Slow” (S) symbols, which correspond to the (relative) duration of notes, such that S = QQ. In this paper we present a linear algorithm for locating the maximum-length substring of a music text t that can be covered by a given rhythm r. An efficient algorithm t...

BACKGROUND About half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (AF). Cox described the surgical cut-and-sew Maze procedure, which is an effective surgical method but has some complications. This study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (RFA) for patients undergoing mitral valve surgery with AF. METH...

Red Light Spotters is a multi-contextual interactive project which aims to create an open and real-time musical environment sharing relations with and extending a natural ambient environment, namely an urban landscape. The basic idea is to convert in real-time the input from a camera sensor recording a urban landscape (Tokyo city, at night) into an electronic musical soundscape. This is achieve...

Beat perception is the ability to perceive temporal regularity in musical rhythm. When a beat is perceived, predictions about upcoming events can be generated. These predictions can influence processing of subsequent rhythmic events. However, statistical learning of the order of sounds in a sequence can also affect processing of rhythmic events and must be differentiated from beat perception. I...
