BACKGROUND Microcystic adnexal carcinoma is a slow-growing, nondescript, locally aggressive, deeply infiltrating neoplasm histologically characterized by an infiltrative pattern of basaloid or squamous cells, a desmoplastic stromal reaction, keratin-filled cysts, and glandular structures. OBJECTIVE Microcystic adnexal carcinoma is uncommon and may be(More)
Grid services offer a number of advantages in the field of medical imaging. Many image processing algorithms are computationally intensive and require high specification hardware or take a long time to run. The prospect of being able to use dedicated clusters of high end workstations on a remote network, or indeed several networks, with only a few clicks of(More)
Evaluation of the smart grid in the presence of dynamic market-based pricing and complex networks of small and large producers, consumers, and distributers is a very difficult task. It not only involves multiple, interacting, heterogeneous cyber-physical domains, but also requires tight integration of power markets, dynamic pricing and transactions, and(More)
The human hand uses a combination of feedforward and feedback mechanisms to accomplish high degree of freedom in grasp control efficiently. In this study, we used a synergy-based control model to determine the effect of sensory feedback on kinematic synergies in the grasping hand. Ten subjects performed two types of grasps: one that included feedback (real)(More)
Kinematic synergies in human hand movements have shown promising applications in dexterous control of robotic and prosthetic hands. We and others have previously derived kinematic synergies from human hand grasping movements using a widely used linear dimensionality reduction method, Principal Component Analysis (PCA). As the human biomechanical system is(More)
Chronic pancreatic insufficiency (CPI) was induced in male Wistar rats by the injection of a zein-oleic acid-linoleic acid solution into their pancreaticobiliary ducts. Animals injected developed severe pancreatic atrophy with fibrosis and greater than 90% loss of pancreatic enzyme content. The animals also developed malabsorption of fat and bentiromide.(More)
Kinematic and neuromuscular synergies have been found in numerous aspects of human motion. This study aims to determine how effectively kinematic synergies in bilateral upper arm movements can be used to replicate complex activities of daily living (ADL) tasks using a sparse optimization algorithm. Ten right-handed subjects executed 18 rapid and 11(More)
Traditionally, repetitive practice of a task is used to learn a new skill, exhibiting as immediately improved performance. Research suggests, however, that a more experience-based rather than exposure-based training protocol may allow for better transference of the skill to related tasks. In synergy-based motor control theory, fundamental motor skills, such(More)
