BACKGROUND
Although laparoscopic surgery has been available for a long time and laparoscopic cholecystectomy has been performed universally, it is still not clear whether open appendectomy (OA) or laparoscopic appendectomy (LA) is the most appropriate surgical approach to acute appendicitis. The purpose of this work is to compare the therapeutic effects and… (More)

Let A be a d-dimensional local ring containing a field. We will prove that the highest Lyubeznik number λ d,d (A) (defined in [5]) is equal to the number of connected components of the Hochster-Huneke graph (defined in [2]) associated to B, where B = ˆ A sh is the completion of the strict Henselization of the completion of A. This was proven by Lyubeznik in… (More)

We prove that the F-jumping numbers of the test ideal τ (X; ∆, a t) are discrete and rational under the assumptions that X is a normal and F-finite variety over a field of positive characteristic p, K X + ∆ is Q-Cartier of index not divisible p, and either X is essentially of finite type over a field or the sheaf of ideals a is locally principal. This is… (More)

Hybrid Underwater Gliders (HUGs) integrate advantages of Autonomous Underwater Gliders (AUGs) with those of Autonomous Underwater Vehicles (AUVs). HUGs with buoyancy engine and the auxiliary propeller, compared with traditional AUGs, get more various and optimal motion modes, including glide in a saw tooth path with single buoyancy engine, thrust as… (More)

Let R be a local ring of prime characteristic. We study the ring of Frobenius operators F(E), where E is the injective hull of the residue field of R. In particular, we examine the finite generation of F(E) over its degree zero component F 0 (E), and show that F(E) need not be finitely generated when R is a determinantal ring; nonetheless, we obtain… (More)

In this paper we consider Artinian modules over power series rings endowed with a Frobenius map. We describe a method for finding the set of all prime annihilators of submodules which are preserved by the given Frobenius map and on which the Frobenius map is not nilpotent. This extends the algorithm by Karl Schwede and the first author, which solved this… (More)

In this article, we solve Grothendieck's localization problem for a certain class of rings that arises from tight closure theory. It is quite essential to use the relative version of the Frobenius map (Radu-Andrè morphism) to investigate the fibers of a flat ring homomorphism of characteristic p > 0. We also give some interesting geometric applications of… (More)
