A 59-year-old male patient presented with a pulsating mass at the left sternal edge weeks after a CABG procedure. CTshowed a false aneurysm of the LIMA (Fig. 1), confirmed by angiography (Fig. 2a). The leakage was treated using a 16-by-3.5-mm Jostent leading to complete lesion thrombosis (Fig. 2b). Fig. 1. Contrast enhanced CT shows a 6 cm diameter left internal mammary artery false aneurysm. F...

The paper describes the design and testing of the depth and heading autopilots for a small Autonomous Underwater Vehicle (AUV) named Maya. Control system design is done using the LQ (Linear-Quadratic) optimization technique based on a mathematical model of the AUV obtained by resorting to analytical and semi-empirical methods. Details of system implementation are given and the results of tests ...

Twenty-seven patients were randomized into two treatment groups following single tooth extraction in the incisor, canine and premolar area. In the test group, the alveolar socket was grafted with Straumann Bone Ceramic (SBC), while in the control group, Bio-Oss deproteinized bovine bone mineral (DBBM) was applied. In both groups, a collagen barrier was used to cover the grafting material. Compl...

Soft tissue closure is a critical factor in preprosthetic surgery and implant placement. In large transverse or vertical bone augmentations, there is often insufficient or very thin mucosa available. Soft tissue dehiscences and bone or implant exposure may result. Based on the application of a periosteal flap, the presented method solves this problem. The flap is prepared in the neighboring are...

INTRODUCTION Arthroscopic repair of the rotator cuff is a demanding surgery. Accurate placement of anchors is key to success. CASE PRESENTATION A 38-year-old woman received arthroscopic repair of her rotator cuff using a double row suture anchor technique. Postoperatively, she developed impingement syndrome which resulted from vertical displacement of a suture anchor once the shoulder was mob...

We show that a buried oxide layer forming a current aperture in an all epitaxial vertical-cavity surface emitting laser has a profound influence on the optical and electrical characteristics of the device. The lateral index variation formed around the oxide current aperture leads to a shift in the cavity resonance wavelength. The resonance wavelength under the oxide layer can thus be manipulate...

Due to its potential to greatly accelerate a wide variety of applications, reconfigurable computing has become a subject of a great deal of research. In this paper, we explore the representation models of 1D routing structure and 2D routing structure, we also focus on the task scheduling that targets these representation models. A fast navigation-placement tree algorithm is proposed to formulat...

Abstract This paper presents an assessment of infill drilling opportunities in a complex multi-layered heterogeneous carbonate formation located Abu Dhabi offshore. The subject field was developed last century and is currently undergoing further development with line drive horizontal wells. being redeveloped for improved oil recovery at higher production rates long An process defined using sect...

Introduction: The maxillary anterior region poses the highest number of aesthetic challenges in implant dentistryas any tooth loss leads to bone resorption and collapse gingival architecture leaving inadequatebone for placement. However, immediate placement provisionalization has been a viableoption replacing failing teeth as it preserves vertical existing osseous gingivalarchitecture. A proper...

Mission performance for small aircraft is often dependent on the turn radius. Various biologically inspired concepts have demonstrated that performance can be improved by morphing the wings in a manner similar to birds and bats; however, the morphing of the vertical tail has received less attention since neither birds nor bats have an appreciable vertical tail. This paper investigates a design ...
