De Haas-van Alphen effect and energy gaps of a correlated two-dimensional electron system in an AlAs two-valley pseudospin system

Anna Fontcuberta i Morral, Dirk Grundler

We report highly sensitive de Haas-van Alphen (dHvA) effect measurements on a high-mobility two-dimensional electron system in an AlAs quantum well. Here two valleys are occupied forming a pseudospin system. At 400 mK, the dHvA effect shows pronounced osci ...

Regional structural characteristics of bovine periodontal ligament samples and their suitability for biomechanical tests

Marzio Bergomi

Mechanical testing of the periodontal ligament requires a practical experimental model. Bovine teeth are advantageous in terms of size and availability, but information is lacking as to the anatomy and histology of their periodontium. The aim of this study ...

Starch-induced implant periapical lesion: A case report

This paper reports an implant periapical lesion (IPL) with a previously unreported etiology. The presence of an osteolytic area around the apex and around the middle portion of a stable Straumann hollow-screw implant was found on periapical radiographs 3.5 ...

A composite biofoam, from research to in vivo validation

Dominique Pioletti, Pierre-Etienne Bourban

Bone tissue engineering aims at developing scaffolds, or porous structures, as supports for cell migration, proliferation and differentiation, in order to favor bone healing. L-poly lactic acid (PLA) foams, which were reinforced or not with β-tricalcium ph ...

Biomechanical evaluation of an artificial bone scaffold in revision total hip arthroplasty

Dominique Pioletti, Sylvain Iff

The Orthopedic Research Laboratory at Radboud University Nijmegen (Prof. Nico Verdonschot) has developed a surgical technique based on bone graft impaction in case of revision total hip arthroplasty. During this development, in vitro mechanical tests have ...

Optical properties of metal-doped carbon based nanocomposite thin films: Comparing experiment to effective medium theories

Josef Andreas Schuler

Nanocomposite thin films exhibit interesting optical properties which differ from those of the pure constituents. Effective medium theories are used to model the dielectric function of the nanocomposite materials. We give an introduction to the theories of ...

With applications to the periodontal ligament: a nonlinear large strain viscoelastic law

Jörn Justiz

The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...

Geometric Alignment and Chromatic Calibration of Serial Radiographic Images

Philippe Thévenaz

Objective—To develop software for automated registration and intensity calibration of serial dental radiographs for the analysis of longitudinal changes in bone density. Methods—Serial dental radiographs were acquired using a positioning device designed to ...

Interacting many-body systems in quantum wells: Evidence for exciton-trion-electron correlations

Benoît Marie Joseph Deveaud, Jean Berney, Marcia Portella Oberli, Victoria Ciulin

We report on the nonlinear optical dynamical properties of excitonic complexes in CdTe modulation-doped quantum wells, due to many-body interactions among excitons, trions, and electrons. These were studied by time and spectrally resolved pump-probe experi ...
