Negative parity states in 16O from coupled-cluster equations

The extension of the coupled-cluster theory to excited states of closed-shell nuclei is presented. The method is applied to the negative parity particle-hole spectrum of ¹⁶O. Some approximations found necessary in the application of the theory at the three-body level are discussed. Numerical calculation bears out characteristic discrepancies to experimental energy levels for some T = 0 states whereas agreement with experiment is found for T = 1 states.     

Modeling,Analysis, and Simulation of Biofilm Formation and Decay

In this article, we give a brief overview of our recent work on continuum mechanical modelling and simulation of microbial films. This comprises some classical tasks of applied mathematics such as computational fluid dynamics, analysis of partial differential equations, and mathematical biology.     

Flow field measurement by tracer photography

Methods of inserting and photographing tracers in an air stream are described. Successive positions of micrometer-sized oil drops are determined in centimeter-sized fields of a low power microscope by triple flash illumination at known intervals of 10 to 500 microseconds. Tracer positions read from the picture are entered into a computer and velocities calculated throughout the field. Some examples of computer displays of velocity fields are presented.     

Particle-hole amplitudes in spherical nuclei

Equations and relations are discussed which allow to calculate particle-hole amplitudes of excited states of spherical nuclei. In particular we investigate the case where the Bethe-Salpeter equation must be solved in both particle-hole channels.     

High-performance genetic analysis using microfabricated capillary array electrophoresis microplates.

This review focuses on some recent advances in realizing microfabricated capillary array electrophoresis (microCAE). In particular, the development of a novel rotary scanning confocal fluorescence detector has facilitated the high-speed collection of sequencing and genotyping data from radially formatted microCAE devices. The concomitant development of a convenient energy-transfer cassette labeling chemistry allows sensitive multicolor labeling of any DNA genotyping or sequencing analyte. High-performance hereditary haemochromatosis and short tandem repeat genotyping assays are demonstrated on these devices along with rapid mitochondrial DNA sequence polymorphism analysis. Progress in supporting technology such as robotic fluid dispensing and batched data analysis is also presented. The ultimate goal is to develop a parallel analysis platform capable of integrated sample preparation and automated electrophoretic analysis with a throughput 10-100 times that of current technology.
