BACKGROUND “Ankle sprain” is a common injury, and although most patients recover with non-operative treatment, more than 20% of patients may develop chronic instability. Numerous surgical techniques have been described for these patients. “Anatomic” procedures, such as the modified Brostrom-Gould procedure (MBG), are generally regarded as the treatment of choice. However, there is little high q...

runoff simulation is a vital issue in water resource planning and management. various models with different levels of accuracy and precision are developed for this purpose considering various prediction time scales. in this paper, two models of ihacres (identification of unit hydrographs and component flows from rainfall, evaporation and streamflow data) and ann (artificial neural network) mode...

This development provides a formalization of directed graphs, supporting (labelled) multi-edges and infinite graphs. A polymorphic edge type allows edges to be treated as pairs of vertices, if multi-edges are not required. Formalized properties are i.a. walks (and related concepts), connectedness and subgraphs and basic properties of isomorphisms. This formalization is used to prove characteriz...

This paper analyzes gender differences in ambiguity and whether they can be explained by differences in personality traits. In an experiment with 347 high school students, we investigate choices under ambiguity and link ambiguity to cognitive and personality traits. Participants value ambiguity less than risk. Women are more risk averse, while men are more ambiguity averse than women. Condition...

Purpose Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. Materials and Methods The ...

Parker for discussing his old and classic publications on yellow dung flies with me via e-mail; Sebastian Domhof for precious statistical advice as well as Lars Reimer for helpful chats on statistics; Ang...

1. Introduction. This is a fascinating paper on an important topic: the choice of predictor variables in large-scale linear models. A previous paper in these pages attacked the same problem using the " LARS " algorithm (Efron, Hastie, Johnstone and Tibshirani [3]); actually three algorithms including the Lasso as middle case. There are tantalizing similarities between the Dantzig Selector (DS) ...

This is a multi-center retrospective study of patients underwent low anterior resection for rectal cancer. Ileostomy had been done to protect lying Colo-rectal anastomosis, closure ileostomy delayed in some due patient own will, surgical complications (anastomotic leak) or coarse chemotherapy. aimed find the effect temporary on post-operative bowel defunction which called Low syndrome (LARS), a...

LPH: As a graduate student at the University of Minnesota, I had the opportunity to take classes from Chris Sims and Tom Sargent. Both emphasized the idea that dynamic econometric models should be viewed as restrictions on stochastic processes. Sims’ classroom development of large sample econometrics broke with the more conventional view of the time of focusing on models with exogenous regresso...
