Midterm clinical experience with a complex-shaped detachable platinum coil system for the treatment of cerebral aneurysms: Trufill DCS Orbit detachable coil system registry interim results

PURPOSE: To report an interim analysis of the registry data and evaluate the performance of Trufill DCS Orbit coils in terms of the stability of initial aneurysmal occlusion. MATERIALS AND METHODS: From May 1, 2004, to February 1, 2006, 291 patients with ruptured or unruptured aneurysms were enrolled in a multiple-center global registry from 37 centers in the United States, Europe, and Latin Ameri

Energy-Centric Scheduling for Real-Time Systems

Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. This, however, might lead to a performance degrada

Applications of high-order harmonics

We review applications of high-order harmonic generation in different fields of physics, from spectroscopic studies of atoms and molecules, to interferometry and plasma diagnostics and nonlinear optics.

Molecular analysis of the O alleles at the blood group ABO locus in populations of different ethnic origin reveals novel crossing-over events and point mutations

The blood group ABO genotypes of 138 group O individuals with three different ethnic origins in Brazil were determined, including Whites, Blacks and Amerindians. Several previously undescribed O alleles were found, predominantly in the Black group, in which about a third of the samples did not conform to previously known O allele structures. It has been well documented for the first time that some

Modeling diffractive final states

I will discuss some aspects of modeling diffractive final states with event generators. In the first part of the talk I will discuss multiple scatterings in hard diffraction in hadron collisions and its effects on gap survival and hadronization corrections. In the second part I will argue that the study of the 'pomeron remnant' in hard diffraction at HERA may be the best way of distinguishing reso

Combining sequence-specific probes and DNA binding dyes in real-time PCR for specific nucleic acid quantification and melting curve analysis

Currently, in real-time PCR, one often has to choose between using a sequence-specific probe and a nonspecific double-stranded DNA (dsDNA) binding dye for the detection of amplified DNA products. The sequence-specific probe has tire advantage that it only detects the targeted product, while the nonspecific dye has the advantage that melting curve analysis can be performed after completed amplifcat

Inomhusluft - egenskaper, påverkan på människor, metoder för förbättringar

Målet med arbetet som presenteras i denna licentiatuppsats är att genomföra en analys av problemkomplexet inomhusluft och att med ledning av denna analys anvisa vägar att minska inneluftproblem i framtida byggande. Utifrån detta har tre delsyften formulerats: (1) Analysera existerande inneluftproblem och i samband därmed beskriva vilka faktorer i inomhusluften som medför problem, vilka faktorer so

Exploring Positional and Functional Candidate Genes for Type 2 Diabetes

Type 2 diabetes (T2D) is a complex, metabolic disorder characterized by hyperglycaemia because of defects in insulin secretion and sensitivity. The rapid increase in T2D is likely to reflect the influence of both genetic and environmental factors in disease development. However, the genetic aetiology of T2D remains largely unknown. Thus, the aim of this thesis was to study the role of genetic vari

Structure of Tetrafluorocyclopropane, Hexafluorocyclobutene, Octofluorocyclopentene, and Related Perfluoroalkene Radical Anions Revealed by ESR Spectroscopic and Computational Studies

Isotropic and anisotropic ESR spectra were observed for the radical anions of hexafluorocyclobutene (c-C4F6-), octafluorocyclopentene (c-C5F8-) and perfluoro-2-butene (CF3CFCFCF3-) in γ-irradiated plastically crystalline neopentane, tetramethylsilane (TMS) and TMS-d12 matrices, or the rigid 2-methyltetrahydrofuran (MTHF) matrix. The isotropic spectra of c-C4F6- and c-C5F8- are characterized by thr

On the interaction between two fixed spherical particles

The variation of the drag (CD) and lift coefficients (CL) of two fixed solid spherical particles placed at different positions relative each other is studied. Simulations are carried out for particle Reynolds numbers of 50, 100 and 200 and the particle position is defined by the angle between the line connecting the centers of the particles and the free-stream direction (a) and the separation dist

An Architecture for Migrating User Interfaces

The MUI project looks at flexible ways of creating user-initiated connections between services in wireless networks. A central idea is to migrate user interfaces from controlled devices to devices with better input/output capabilities. The paper shows the different parts of the MUI architecture, and motivates design choices. An initial implementation and a framework for building MUI services are d
