BACKGROUND Infarcts of the rostral brainstem often cause vertical gaze palsies but may also produce inappropriate convergence that manifests as pseudoabducens palsy and convergence-retraction nystagmus (CRN). Although the substrate for vergence has been defined in the monkey as lying dorsal and lateral to the oculomotor nucleus, the human homologue is(More)
An environment for designing virtual instruments with 3D geometry has been prototyped and applied to real-time sound control and design. It enables a sound artist, musical performer or composer to design an instrument according to preferred or required gestural and musical constraints instead of constraints based only on physical laws as they apply to an(More)
We present a granular synthesis (GS) technique that produces environmental-like sounds using sampled sound grains and meso-time control functions. This approach is related to physical modeling (PM) (Smith, 1992; VŠlimŠki & Takala, 1996) and traditional granular synthesis (GS) (Roads, 1996, 299; Truax, 1988) but we have worked on two issues that have been(More)
A purely aesthetic approach may be problematic when artists wish to deal with the external world as part of their work. The work of R. Murray Schafer in formulating soundscape studies is described, as well as the author’s extension of that work within a communicational framework. Soundscape composition is situated within a continuum of possibilities, each(More)
A 12-year-old juvenile diabetic was inadvertently given 500 ml of hypertonic saline intravenously. He developed hypernatremia, hyperosmolality, metabolic acidosis, and hyperglycemia. Seizures and stupor ensued, followed by coma and death. Computerized cranial tomography revealed numerous small subcortical hemorrhages that were verified postmortem.
Embolization therapy is reported in three patients bleeding from metastatic carcinoma of the breast. Two had life threatening hemorrhage from sternal erosion; internal mammary arteriography indicated encasement, false aneurysm formation or tumor blush. The third patient had intermittent bleeding of extensive fungating axillary and anterior chest wall(More)
