BACKGROUND Conventional placement of a wireless esophageal pH monitoring device in the esophagus requires initial endoscopy to determine the distance to the gastroesophageal junction. Blind placement of the capsule by the Bravo delivery system is followed by repeat endoscopy to confirm placement. Alternatively, the capsule can be placed under direct vision during endoscopy. Currently there are ...

This paper presents a statistical method that estimates a sequence of musical notes from a vocal F0 trajectory. Since the onset times and F0s of sung notes are considerably deviated from the discrete tatums and pitches indicated in a musical score, a score model is crucial for improving timefrequency quantization of the F0s. We thus propose a hierarchical hidden semi-Markov model (HHSMM) that c...

The genus Trachionus Haliday, 1833 (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is reported for the first time from China. The genus is represented by four new species from Shaanxi province (NW China), which are described and illustrated. An identification key to the species in China is presented, a key to the genera of the Trachionus group and notes on the relationships with other Palaearct...

Most of Mathematics 281 deals with some fundamental ideas about and properties of the real numbers and continuous functions. These ideas and properties include sequences and series (which are studied in some first-year calculus), the least upper bound property, elementary topology of R and R d , convergence and uniform convergence of series of functions, and term-by-term differentiation and int...

ree access to the articles is becoming more popular since it gives thousands of researchers access to millions of publications resulting in higher visibility and receiving much more citations, which often times might be the ultimate goal. for this reason, authors may seek a way to make the papers easily accessible to other researchers via uploading the full text to their personal website and/or...
