Parametric kernel methods currently dominate the literature regarding the construction of animal home ranges (HRs) and utilization distributions (UDs). These methods frequently fail to capture the kinds of hard boundaries common to many natural systems. Recently a local convex hull (LoCoH) nonparametric kernel method, which generalizes the minimum convex(More)
BACKGROUND Bone-containing vascularized grafts have been used successfully to reconstruct post-cancer surgical defects. Dental implants can be placed in these bone-containing grafts to allow implant-supported prosthodontic reconstruction of these patients. PURPOSE The aim of this study was to evaluate the survival of dental implants used in the(More)
This paper explains how the Unified Modeling Language (UML), and powerful modeling constructs originally developed for the modeling of complex real-time systems in the Real-Time Object-Oriented Modeling language (ROOM), have been combined into UML for Real-Time. It is directed at developers of complex real-time software systems (e.g., telecommunications,(More)
BACKGROUND Advances in GPS technology have created both opportunities in ecology as well as a need for analytical tools that can deal with the growing volume of data and ancillary variables associated with each location. RESULTS We present T-LoCoH, a home range construction algorithm that incorporates time into the construction and aggregation of local(More)

A 'perforator flap' is a flap of skin or subcutaneous tissue that is based on the dissection of a 'perforating vessel'. Over the past few years a large number of 'perforator flaps' have been devised and described. By reducing any muscle harvest and trauma to a minimum, perforator flaps aim to minimize donor site morbidity whilst providing the reconstructive(More)
During the past 80 years a number of theories about the pathogenesis of osteoradionecrosis (ORN) have been proposed, with consequent implications for its treatment. Until recently tissue hypoxia and its consequences were accepted as the primary cause, and this led to the use of hyperbaric oxygen (HBO) for both treatment and prevention of complications of(More)
Horner's syndrome, as a complication of radical neck dissection, is given little attention in textbooks of head and neck surgery. To investigate which topographical anatomic factors, if any, might influence damage to the sympathetic chain during neck dissection, we undertook a series of 12 cadaveric neck dissections. The axial position of the cervical(More)
Carcinomas are characterized by invasion of malignant cells into the underlying connective tissue and migration of malignant cells to form metastases at distant sites. These processes require alterations in cell-cell and cell-extracellular matrix interactions. As cell adhesion molecules play a role in cell-cell and cell-extracellular matrix adhesion and(More)
