This paper gives an overview of the OBST persistent object management system. OBST has been developed by the Forschungszentrum Informatik (FZI) as a contribution to the STONE project.1 The paper summarizes the design objectives and the current status of OBST, and highlights forthcoming developments with the system.
We discover two distinct topological pathways through which the pentagonal Cairo tiling (P5), a structural model for single-layer $A{B}_{2}$ pyrite materials, respectively transforms into crystalline rhombus-hexagon (C46) and random rhombus-pentagon-hexagon (R456) tilings, by continuously introducing Stone-Wales (SW) defects. find these transformations are controlled orientation correlations am...
Prediction of the production rate of the cutting dimensional stone process is crucial, especially when chain saw machines are used. The cutting dimensional rock process is generally a complex issue with numerous effective factors including variable and unreliable conditions of the rocks and cutting machines. The Group Method of Data Handling (GMDH) type of neural network and Radial Basis Functi...
This paper is a contribution to the theory of what might be termed $0$-dimensional non-commutative spaces. We prove that associated with each inverse semigroup $S$ Boolean presented by abstract versions Cuntz-Krieger relations. call this Exel completion and show it arises from Exel's tight groupoid under Stone duality.
Background and Aims: Accurate recording of implant location is required to achieve passive fit and have the implants without stress concentration. The aim of this in-vitro study was to evaluate the dimensional and angular accuracy of open-tray and closed-tray impression techniques using polyether impression material and also to assess the surface detail reproduction of the tooth while impressio...
BACKGROUND The aim of the present study is to investigate the clinical relevance of aortic calcification in urolithiasis patients. METHODS Between January 2010 and September 2014, 1221 patients with urolithiasis were treated in Oyokyo Kidney Research Institute and Hirosaki University Hospital. Among these, 287 patients (Stone group) on whom adequate data were available were included in this r...
Introduction: Cholelithiasis is a common disease. Since about 10 to 15 percent of choletithiasis patients have CBD (Common Bile Duct) stone as well as, the detection of CBD stone seems crucial in these patients. Regarding to cholodocholithiasis, the stone is extracted by ERCP (Endoscopic Retrograde Cholangio Pancreatography) and then, cholecystectomy is performed. The remaining CBD stone may ca...
INTRODUCTION Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone dis...
