is a typical story. a patient arrives at the emergency room. he was well when he went to bed and then he woke up with symptoms suggestive of stroke several hours later. even without further scrutiny, the clinician determines that intravenous thrombolytic therapy is contraindicated. end of story. Such is the plight of patients with wake-up stroke. Can we do more? Can we do better? Wake-up stroke...

Linear stability analysis of the three dimensional plane wake flow is performed using a mapped finite di?erence scheme in a domain which is doubly infinite in the cross–stream direction of wake flow. The physical domain in cross–stream direction is mapped to the computational domain using a cotangent mapping of the form y = ?cot(??). The Squire transformation [2], proposed by Squire, is also us...

Swimming and flying animals generate unsteady locomotive forces by delivering net momentum into the fluid wake. Hence, swimming and flying forces can be quantified by measuring the momentum of animal wakes. A recently developed model provides an approach to empirically deduce swimming and flying forces based on the measurement of velocity and vortex added-mass in the animal wake. The model is c...

PURPOSE/OBJECTIVES To identify factors associated with sleep-wake disturbances in pediatric and adult survivors (aged older than 18 years) of pediatric brain tumors. DATA SOURCES A computerized literature search was completed using MEDLINE, CINAHL, CancerLit, Dissertation Abstracts International, and PsycINFO. The search and a personal communication with one author discovered 25 English-langu...

Sleep-wake schedule disorder is defined by DSM-III-R as a mismatch between the normal sleep-wake schedule for a person's environment and his or her circadian sleep-wake pattern. The authors report a case in which a sleep-wake schedule disorder arose after a closed head injury. Sleep-wake schedule disorder has not been described as an outcome of closed head injury. As patients with sleep-wake sc...

A high-order spectral difference flow solver for compressible three-dimensional NavierStokes (N-S) equations has been utilized to numerically simulate the unsteady flow over the NACA 0012 airfoil undergoing a sinusoidal pitching motion at the Reynolds (Re) number of 12600. The effects of the reduced frequency and Strouhal number on the wake vortex structure and force coefficient have been studi...
