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...

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 ...

The integration of different existing tools, each of them not covering the whole life cycle, to a SEE (Software Engineering Environment) is an actual task. There are two main mechanisms of integration. The fIrst one is the vertical integration, that means, that a common user interface and a common data base are available for the tools to be assembled into a CASE Environment. ( The second one is...

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...

Let T be the quasi-nilpotent DT-operator. By use of Voiculescu’s amalgamated R-transform we compute the momets of (T −λ1)∗(T − λ1) where λ ∈ C, and the Brown-measure of T + √ Y , where Y is a circular element ∗-free from T for > 0. Moreover we give a new proof of Śniady’s formula for the moments τ(((T ∗)kT )) for k, n ∈ N.

Neglected patella tendon ruptures require reconstruction using tendon grafts. The LARS ligament has been successfully used in cruciate and collateral knee ligament reconstruction. We present a technique using LARS ligament for the reconstruction of a chronic patella tendon rupture in a low-demand patient. The result after 1-year follow-up was deemed successful.
