Symmetry in 3D Geometry: Extraction and Applications

The concept of symmetry has received significant attention in computer graphics and computer vision research in recent years. Numerous methods have been proposed to find, extract, encode and exploit geometric symmetries and high‐level structural information for a wide variety of geometry processing tasks. This report surveys and classifies recent developments in symmetry detection. We focus on elucidating the key similarities and differences between existing methods to gain a better understanding of a fundamental problem in digital geometry processing and shape understanding in general. We discuss a variety of applications in computer graphics and geometry processing that benefit from symmetry information for more effective processing. An analysis of the strengths and limitations of existing algorithms highlights the plenitude of opportunities for future research both in terms of theory and applications.     

Strong coupling effects on the upper critical field of the heavy-fermion superconductor UBe13

The upper critical fieldH _c2 (T) of a high quality single crystal of UBe₁₃ is studied with very low noise resistivity measurements. It shows a large but finite slope of —45 T/K, an unusual temperature dependence with an inflexion point atT/T _C 0.5 and a large saturated limit forT 0 ofH _c2 (0) = 14 T. The complete temperature dependence ofH _c2 (T) can be described by a simple model of strong coupling superconductor, assuming a full Pauli limitation and the occurence of a non-uniform superconducting state (FFLO state) at low temperature.     

Toward formalizing domain modeling semantics in language syntax

Information systems are situated in and are representations of some business or organizational domain. Hence, understanding the application domain is critical to the success of information systems development. To support domain understanding, the application domain is represented in conceptual models. The correctness of conceptual models can affect the development outcome and prevent costly rework during later development stages. This paper proposes a method to restrict the syntax of a modeling language to ensure that only possible configurations of a domain can be modeled, thus increasing the likelihood of creating correct domain models. The proposed method, based on domain ontologies, captures relationships among domain elements via constraints on the language metamodel, thus restricting the set of statements about the domain that can be generated with the language. In effect, this method creates domain specific modeling languages from more generic ones. The method is demonstrated using the Unified Modeling Language (UML). Specifically, it is applied to the subset of UML dealing with object behavior and its applicability is demonstrated on a specific modeling example.     

Latanoprost for uncontrolled glaucoma in a compassionate case protocol

OBJECTIVE: This study examined the effects of change in interpersonal stress on disease activity among 41 women with rheumatoid arthritis (RA). METHODS: Measures of everyday stressful events and perceived stress were collected weekly for twelve weeks and related to disease activity in a series of pooled time-series regression analyses. RESULTS: Increases in the number of interpersonal stressors in the same week and one week prior were associated with increases in disease activity. Pain from joint tenderness also was significantly related to a decrease in stressful events one week later. A subgroup of 20 patients showed a significant increase in interpersonal stress from baseline during the course of the study. For this group, significant elevations in DR + CD3 cells, sIL-2R, clinician's rating of disease, and self-reports of joint tenderness were found during the week of increased interpersonal stress. CONCLUSIONS: Interpersonal stress appears to be associated with increases in disease activity among RA patients.     

The LTPL-E tasking proposals

The Long Term Procedural Language Committee of the International Purdue Workshop for the Standardization of Industrial Computer Systems has studied, over a number of years, the design of a programming language suitable for use in industrial real-time systems. Various parts of a language suitable for this kind of application have been designed during this period. This paper presents the results of part of this work. In particular it describes the tasking facilities that are seen to be necessary in the industrial real-time environment. The paper concludes with a comparison of the proposed features with those in Ada.
