Scaling relationships between skeletal dimensions and body mass in extant birds are often used to estimate body mass in fossil crown-group birds, as well as in stem-group avialans. However, useful statistical measurements for constraining the precision and accuracy of fossil mass estimates are rarely provided, which prevents the quantification of robust(More)
With the recent appearance of netbooks and low-cost tablet PCs, a study was undertaken to explore their potential in the classroom and determine which of the two device types is more suitable in this setting. A collaborative learning activity based on these devices was implemented in 5 sessions of a graduate engineering course of 20 students, most of whom(More)
The subject of Non-Photorealistic Rendering (NPR) is one which tends towards a certain, small set of targeted appearances. Work in NPR-in particular in real-time graphics-is generally aimed at a classic cel-animated, "cartoon" visual style-that is, solid black outlines with clamped ramp shading. While this look is often arresting and interesting, it is a(More)
OBJECTIVES To evaluate how accurate a 12-core transrectal biopsy derived low-risk prostate cancer diagnosis is for an active surveillance programme by comparing the histological outcome with that from confirmatory transperineal sector biopsy. SUBJECTS AND METHODS The cohort included 166 men diagnosed with low volume Gleason score 3+3 prostate cancer on(More)
OBJECTIVE To document the learning curve for the laparoscopic radical prostatectomy (LRP) procedure and discuss the optimal usage of prospectively documented outcome data for reporting a surgeon's performance. MATERIALS AND METHODS Using prospectively collected data from the first series of patients to undergo LRP by two surgeons in the same institution,(More)

ABSTRACT Understanding intensity coding and auditory learning are basic concerns of research on the auditory central pathway. There is no unifying model of(More)
Introduction Pitch is a fundamental attribute of sound, which has led to extensive research on pitch processing, categorization, and memory with the goal of elucidating the complex workings of the auditory system. The phenomenon of absolute pitch (AP), the ability to identify or produce a specified pitch without external reference, provides a unique(More)
Introduction Imagine after our topic presentation, we go to a crowded pub to celebrate. You are trying hard to ignore those eighties tunes blaring out of the loudspeakers while you are chatting with your colleagues. Suddenly, this familiar melody from a Mozart's piano concerto grabs your attention – yes, your cell phone alerts you that your partner just(More)
