Objective. There have been surgical procedures to reconstruct the gastrointestinal continuity after distal gastrectomy. This study is aimed at comparing the surgical outcomes of reconstructing gastrointestinal continuity by the method of Finsterer an

In 2014, Payne-Wood proved that every non-collinear set $P$ of $n$ points in the Euclidean plane contains a point in at least $\dfrac{n}{37}$ lines determined by $P.$ This is a remarkable answer for the conjecture, which was proposed by Erd\H{o}s, th

A k -ended tree is a tree with at most k leaves. In this note, we give a simple proof for the following theorem. Let G be a connected graph and k be an integer ( k ≥ 2 ). Let S be a vertex subset of G such that α G ( S ) ≤ k + κ G ( S ) − 1 .

Let T be a tree, a vertex of degree one is called a leaf. The set of leaves of T is denoted by $${\mathrm{Leaf}}(T)$$. The subtree $$T-{\mathrm{Leaf}}(T)$$ of T is called the stem of T and denoted by $${\mathrm{Stem}}(T)$$. In this paper, we give a s

In this article, we establish a new estimate for the Gaussian curvature of open Riemann surfaces in Euclidean three-space with a specified conformal metric regarding the uniqueness of the holomorphic maps of these surfaces. As its applications, we gi

Let $T$ be a tree, a vertex of degree one is a leaf of $T$ and a vertex of degree at least three is a branch vertex of $T$. The set of leaves of $T$ is denoted by $L(T)$ and the set of branch vertices of $T$ is denoted by $B(T)$. For two distinct ver
