This paper describes a predominant-pitch estimation method that enables us to build a realtime system detecting melody and bass lines as a subsystem of our music scene description system. The purpose of this study is to build such a real-time system that is practical from the engineering viewpoint, that gives suggestions to the modeling of music understanding, and that is useful in various appl...

BACKGROUND Otitis media (OM) is amongst the most common childhood diseases and is associated with multiple microbial pathogens within the middle ear. Global and temporal monitoring of predominant bacterial pathogens is important to inform new treatment strategies, vaccine development and to monitor the impact of vaccine implementation to improve progress toward global OM prevention. METHODS A...

The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum. C. sativum was predominant with 84% of samples...

In India, mutations in Cytochrome P450 (CYP1B1) are a predominant cause of not only primary congenital glaucoma (PCG) but also involved in primary open angle glaucoma (POAG) and juvenile onset glaucoma (JOAG). After ethical clearance, 100 POAG patients, 30 primary angle closure glaucoma (PACG) patients and 130 ethnically matched controls were recruited in this study. Genomic DNA was is...

UNLABELLED Tremor in essential tremor (ET) and Parkinson's disease (PD) usually present specific electrophysiologic profiles, however amplitude and frequency may have wide variations. OBJECTIVE To present the electrophysiologic findings in PD and ET. METHOD Patients were assessed at rest, with posture and action. Seventeen patients with ET and 62 with PD were included. PD cases were cluster...

This paper describes a robust method for estimating the fundamental frequency (F0) of melody and bass lines in monaural realworld musical audio signals containing sounds of various instruments. Most previous F0-estimation methods had great difficulty dealing with such complex audio signals because they were designed to deal with mixtures of only a few sounds. To make it possible to estimate the...
