Visualizing The Phonon Wave Function, Scott C. Johnson, Thomas D. Gutierrez

Physics

A phonon often is described as ‘‘a quantum of lattice vibration,’’ but this description can be difficult to reconcile with the wave functions explored in a typical undergraduate quantum mechanics class. A phonon wave function is similar to the harmonic oscillator wave functions studied in introductory quantum mechanics, except that it is many-dimensional. We suggest a way to visualize the probability density for this very high-dimensional wave function. The resulting pictures are especially clear and intuitive for a coherent state, which is both a good approximation to a sound wave and a discrete analog to laser light. These pictures can …

Ontology-Based Semantic Classification Of Unstructured Documents, Ching Kang Cheng, Xiao Shan Pan, Franz J. Kurfess

Computer Science and Software Engineering

As more and more knowledge and information becomes available through computers, a critical capability of systems supporting knowledge management is the classification of documents into categories that are meaningful to the user. In a step beyond the use of keywords, we developed a system that analyzes the sentences contained in unstructured or semi-structured documents, and utilizes an ontology reflecting the domain knowledge for a semantic classification of the documents. An experimental system has been implemented for the analysis of small documents in combination with a limited ontology; an extension to larger sets of documents and extended ontologies, together with an …

A Biomechanical Comparison Of Three Sternotomy Closure Techniques, David J. Cohen, Lanny V. Griffin

Biomedical Engineering

Background. A biomechanical study of three sternotomy closuretechniques (figure-of-eight stainless-steel wires, PectofixDynamic Sternal Fixation [DSF] stainless-steel plates, and figure-of-eightstainless-steel cables) was conducted to compare strength andstiffness variables in three clinically relevant loading modes(anterior-posterior shear, longitudinal shear, and lateral distraction).

Methods. All tests were conducted on polyurethane foam sternalmodels that simulate the properties of cancellous bone. Eachmodel was divided longitudinally and reconstructed using oneof the sternotomy closure repair techniques. Tests were performedusing a materials testing system that applies a continuouslyincreasing amount of force in one direction to the model untilit catastrophically breaks. A total of six trials of each …
