See related article, pages 2379–2383. Unlike in acute myocardial infarction, the underlying pathophysiological mechanism of vascular arterial occlusion in acute stroke is heterogeneous. Composition of cerebral embolic material may vary, depending on specific endothelial and flow conditions of the embolic source. Old, platelet-rich, and well-organized thrombi formed under flow conditions have be...

BACKGROUND Previous data using T1-weighted MRI demonstrated neck muscle fat infiltration (MFI) in patients with poor functional recovery following whiplash. Such findings do not occur in those with milder symptoms of whiplash, chronic non-traumatic neck pain or healthy controls, suggesting traumatic factors play a role. Muscle degeneration could potentially represent a quantifiable marker of po...

The framework and control structure of an image understanding system SIGMA arc presented. SIGMA consists of three experts: Geometric Reasoning Expert (GRE) for spatial reasoning. Model Selection Expert (MS'E) for appearance model selection, and Low Level Vision Expert (LIVE) for knowledge—based picture processing. Tills paper mainly describes the control mechanism for the spatial reasoning by G...

Fig. 2 Representative T1-w GRE and IR-FLASH images (a), correlation of MRI-measured IRE zones with ablated necrosis area (♦,T1-w GREmeasured IRE zone; ○, IR-FLASH measured IRE zone) (b) and Bland-Altman plot comparing T1-w GRE and IR-FLASH with ablated necrotic area (c and d, respectively). Early visualization of the irreversible electroporation ablated tissue margin by contrast enhanced imagin...

In this paper, we propose to reinterpret the problem of generating referring expressions (GRE) as the problem of computing a formula in a description logic that is only satisfied by the referent. This view offers a new unifying perspective under which existing GRE algorithms can be compared. We also show that by applying existing algorithms for computing simulation classes in description logic,...

A distributed Brillouin fiber sensor has been employed to detect localized pipe-wall buckling in an energy pipe by measuring the longitudinal and hoop strain distributions along the outer surface of the pipe for the first time. The locations of the localized pipe-wall buckling are found and distinguished using their corresponding strain-load data. The formation of the buckling process for the c...

Care of the elderly population with diabetes may not be restricted to the management of hyperglycemia, associated risk factors, and specific diabetic complications. An integrated approach should also include the assessment and management of gerontological problems. Both diabetes mellitus and aging interact toward the direction of the increased incidence of geriatric syndromes. Education is a co...
