| 1 | Chebfun and numerical quadrature显示文摘Chebfun is a Matlab-based software system that overloads Matlab's discrete operations for vectors and matrices to analogous continuous operations for functions and operators.We begin by describing Chebfun's fast capabilities for Clenshaw-Curtis and also Gauss-Legendre,-Jacobi,-Hermite,and-Laguerre quadrature,based on algorithms of Waldvogel and Glaser,Liu and Rokhlin.Then we consider how such methods can be applied to quadrature problems including 2D integrals over rectangles,fractional derivatives and integrals,functions defined on unbounded intervals,and the fast computation of weights for barycentric interpolation. | HALE Nicholas TREFETHEN Lloyd N | 2012 | Science China Mathematics2012，55，9： | 1 |

| 3 | Conscious or unconscious:The impact of sedation choice on colon adenoma detection显示文摘AIM: To determine if anesthesiologist-monitored useof propofol results in improved detection of adenomaswhen compared with routine conscious sedation. METHODS: This retrospective study was conductedat two separate hospital-based endoscopy units whereapproximately 12 000 endoscopic procedures are permed annually, with one endoscopy unit exclusivelyusing anesthesiologist-monitored propofol. Three thousand two hundred and fifty-two patients underwent initial screening or surveillance colonoscopies. Our primaryend point was the adenoma detection rate, def ined asthe number of patients in whom at least one adenomawas found, associated with the type of sedation. RESULTS: Three thousand two hundred and fi ftytwooutpatient colonoscopies were performed by fi ve selected endoscopists. At least one adenoma was detected in 27.6% of patients (95% CI = 26.0-29.1) with no difference in the detection rate between the anesthes-ologist propofol and group and the gastroenterologist-midazolam/fentanyl group (28.1% vs 27.1%, P = 0.53). CONCLUSION: The type of sedation used during colonoscopy does not affect the number of patients in whom adenomatous polyps are detected. | Mark Metwally Nicholas Agresti William B Hale Victor Ciofoaia Ryan O'Connor Michael B Wallace Jonathan Fine Yun Wang Seth A Gross | 2011 | World Journal of Gastroenterology2011，17，34： | 1 |
