We present the in utero appearances and postmortem radiographic findings of two sib fetuses, a male and a female, with features suggestive of kyphomelic dysplasia. The fetuses had severe bowing of the long bones, short, flared ribs, platyspondyly, metaphyseal flaring, skin dimpling, with normal external genitalia and karyotypes and a normal pregnancy. They were born to a mother with features of...

Case presentation A 6-month-old infant presented with a longstanding persistent cough, episodic spells of shortness of breath, gasping-like efforts after feeding, and an unusual noise while breathing, and was reported to have turned blue on two occasions after feeding. A chest X-ray showed significant narrowing of the trachea 2 cm above the carina. An upper gastro-intestinal study (Fig. 1) show...

Force-feedback devices can provide haptic feedback during interaction with physical models for sound synthesis. However, low-end devices may not always provide high-fidelity display of the acoustic characteristics of the model. This article describes an enhanced handle for the Phantom Omni containing a vibration actuator intended to display the highfrequency portion of the synthesized forces. M...

The understanding of different bowing strategies can provide key concepts for the modelling of music performance. We report here an exploratory study of bowing gestures for a viola player and a violin player in the case of bow strokes performed at different frequencies. Bow and arm movements as well as bow pressure on strings were measured respectively with a 3D optical motion capture system an...

Detailed studies are reported on the photoluminescence of InAsSb/ InAs multiple quantum wells grown by molecular beam epitaxy on InAs substrates with the Sb mole fraction ranging from 0.06 to 0.13. From 4 K photoluminescence the band alignment was determined to be staggered type II. By comparing the emission peak energies with a transition energy calculation it was found that both the conductio...

We describe the ongoing development of a system to support the teaching of good posture and bowing technique to novice violin players. Using an inertial motion capture system we can track in real-time: i) a player’s bowing action (and measure how it deviates from a target trajectory); ii) whether the player is holding their violin correctly. We detail some initial experiments that show that vib...

There is increasing attention to medical problems of musicians. Many studies find a high prevalence of work-related musculoskeletal disorders in musicians, ranging from 73.4% to 87.7%, and string players have the highest prevalence of musculoskeletal problems. This paper examines the various positions and movements of the upper extremities in string players: 1) basic postures for holding instru...

In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment of the femoral component in total knee arthroplasty (TKA). There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittal femoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line (DACL) ...

Lossless bowed strings have usually been thought to possess a motion discovered by Helmholtz in 1863. However, it was shown [Acustica 44, 194-206 {1980)] by the author that a more complicated standing wave motion, the $ motion, exists on such strings provided both the bowing distance and bowing force are above certain minimum values. This paper explores S-motion harmonics which give arise to wa...

We propose an expressive performance model for celtic fiddle based on the analysis of audio and bowing gestures of real performances. Existing expressivity models deal with perceptual features such as timing deviations or dynamics, but in some cases perceptual features are not enough. We propose a model not only informed with perceptual features but also with bowing gestures which are acquired ...
