Traditional tracing systems are often limited to recording a fixed set of basic program events. This limitation can frustrate an application or compiler developer who is trying to understand and characterize the complex behavior of software systems such as a Java program running on a Java Virtual Machine. In the past, many developers have resorted to(More)
We study the long time evolution of a quantum particle interacting with a random potential in the Boltzmann-Grad low density limit. We prove that the phase space density of the quantum evolution defined through the Husimi function converges weakly to a linear Boltzmann equation. The Boltzmann collision kernel is given by the full quantum scattering cross(More)
Hyaluronan (HA) and its biosynthetic enzymes, HA synthases (HAS1, 2, and 3) are thought to participate in cancer progression. We have shown previously that HA production and HAS3 expression are increased in metastatic colon carcinoma cells (SW620) when compared with cells isolated from a primary tumor (SW480). Because invasion of the extracellular matrix is(More)
BACKGROUND The Accreditation Council for Graduate Medical Education Outcomes Project mandates data-driven improvements to training programs. Few outcomes measures exist in plastic surgery. The purpose of this study was to determine how well we presently train plastic surgery residents within the context of the council's competencies and how well those(More)
This study examines proliferative activity in tumor cells of patients with histologically documented invasive breast carcinoma treated with magnetic resonance-guided interstitial laser photocoagulation (MR-GILP). Immunohistochemical marker for proliferating cell nuclear antigen (PCNA), a nuclear protein abundant in actively proliferating cells, is used. The(More)
It has been shown recently that uid limit models provide the means to substantially simplify the stability analysis of multiclass queueing networks. This paper begins to address the most natural second question: do uid models provide a tool for developing high performance scheduling policies for queueing networks? A linear program is constructed to give(More)
The task of developing, tuning, and debugging compiler optimizations is a difficult one which can be facilitated by software visualization. There are many characteristics of the code which must be considered when studying the kinds of optimizations which can be performed. Both static data collected at compile-time and dynamic runtime data can reveal(More)
The Java Intermediate Language (JIL) is a subset of XML and SGML described in this document. Its goal is to provide an intermediate representation of Java source code suitable for machine use. JIL benefits from the features of XML, such as extensibility and portability, while providing a common ground for software tools. The following document discusses the(More)
