The aim of this study was to evaluate in vivo the clinical applicability of two electronic apex locators (EALs) - Apex (Septodont) and iPex (NSK) - in different groups of human teeth by using radiography. The working lengths (WLs) of 100 root canals were determined electronically. The EAL to be used first was chosen randomly and a K-file was inserted into the root canal until the EAL display in...

The apex atom plays a key role in STM tunneling, in particular if subtle effects like atomic and chemical resolution on metal alloys are considered. In order to provide comprehensive data on the electronic structure of realistic tips we have calculated tungsten (100) films with single apex atoms by first principles molecular dynamics and full potential methods. Molecular dynamics using ultrasof...

During the last few years, the network research community and the industry have been working on the design of an alternate Internet Routing Architecture aiming at solving the issues arising in the current architecture. It is widely accepted that applying a Locator/ID Separation paradigm would result in a more scalable and flexible architecture. As the name suggests, in Locator/ID Separation the...

This document describes how inter-domain multicast routing will function in an environment where Locator/ID Separation is deployed using the Locator/ID Separation Protocol (LISP) architecture.
