Data assimilation techniques, developed in the last two decades mainly for weather prediction, produce better forecasts by taking advantage of both theoretical/numerical models and real-time observations. In this paper, we explore the possibility of applying the data-assimilation techniques known as 4D-VAR to the prediction of solar flares. We do so in the(More)
This paper focuses on the role of sensitivity analysis in studies of water transport in the environmental and geophysical sciences. Sensitivity analysis is useful in model development to determine how changes in parameter input will affect a model's response. It is also used in data assimilation to incorporate observations into a model. The adjoint method(More)
Sampling of the urinary bladder (UB) in radical cystectomy specimens is usually performed by obtaining sections through the lesions taken in rather random planes. The technique is hindered by the difficulty in identifying the anatomical relationship of the tumor with the remaining urinary bladder. Fifty radical cystectomy specimens were bisected in the(More)
A 38-year-old man presented with a 3-month history of night sweats, nonproductive cough, and weight loss. He denied chest pain or shortness of breath. A transesophageal echocardiogram showed a large mass adjacent to the aortic root likely arising from the pericardium or the left ventricle (Figure 1 and Movie I in the online-only Data Supplement).
