Effective postprandial glucose control is important to management for subjects with diabetes mellitus. In this work, a data-driven meal bolus decision method proposed without the need of subject-specific parameters. The dynamics learnt using Gaussian process regression. Considering asymmetric risks hyper- and hypoglycemia uncertainties in predicted trajectories, an risk-sensitive cost function ...

conclusions the automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. however, bolus tracking is associated with reduced variability for liver enhancement among different patients. results forty-eight patients (23 male, 25 female, mean age=56.4±13.5 years) were included. the contrast enhanceme...

An investigation of a deep electrolytic tank, applied as a lifting-surface calculator, has been made. The reasons for the initial choice of apparatus, and its subsequent behaviour are .detailed. The calculator was developed for use with the investigation of plane surfaces, plane control surfaces and a symmetrically cambered wing. The results have been compared with existing theoretical and expe...

BACKGROUND Despite growing number of intraocular lens power calculation formulas, there is no evidence that these formulas have good predictive accuracy in pediatric, whose eyes are still undergoing rapid growth and refractive changes. This study is intended to compare the prediction error and the accuracy of predictability of intraocular lens power calculation in pediatric patients at 3 month ...

PURPOSE Hip fractures are associated with poor prognosis in elderly patients partly due to the high rate of postoperative complications. This study was aimed to investigate whether the surgical risk calculator is suitable for predicting postoperative complications in elderly Chinese patients with hip fractures. METHODS The incidence of postoperative complications among 410 elderly patients wi...

Pulmonary arterial hypertension (PAH) is a severe and often deadly disease, originating from an increase in pulmonary vascular resistance. Its prevention and treatment are of vital importance to public health. A group of medical researchers proposed a calculator for estimating the risk of dying from PAH, available for a variety of computing platforms and widely used by health-care professionals...
