            superconductors tailored on the nanometre-scale

High- T c superconductors are characterized by an unusually small coherence length, which amounts to a few angstroms only. As the coherence length is the length scale in which a superconductor has to be structured to achieve Josephson junction behaviour, considerable effort has been devoted by many groups to modify high- T c films in the nanometre scale. Because the high- T c cuprates do not lend themselves for nanostructuring, new concepts have to be developed to achieve this goal. These developments will be discussed and an overview of the state of the art of the field will be presented with a special focus on the ultimate limitations of nanoscale structuring of superconductors.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.

Fetal Fraction

The reliability of non-invasive prenatal testing is highly dependent on accurate estimation of fetal fraction. Several methods have been proposed up to date, utilizing different attributes of analyzed genomic material, for example length and genomic location of sequenced DNA fragments. These two sources of information are relatively unrelated, but so far, there have been no published attempts to combine them to get an improved predictor. We collected 2454 single euploid male fetus samples from women undergoing NIPT testing. Fetal fractions were calculated using several proposed predictors and the state-of-the-art SeqFF method. Predictions were compared with the reference Y-based method. We demonstrate that prediction based on length of sequenced DNA fragments may achieve nearly the same precision as the state-of-the-art methods based on their genomic locations. We also show that combination of several sample attributes leads to a predictor that has superior prediction accuracy over any single approach. Finally, appropriate weighting of samples in the training process may achieve higher accuracy for samples with low fetal fraction and so allow more reliability for subsequent testing for genomic aberrations. We propose several improvements in fetal fraction estimation with a special focus on the samples most prone to wrong conclusion.

Model Driven

Model Driven Development (MDD) is by many considered a promising approach for software development. This article reports the results of a systematic survey to identify the state-of-the-art within the topic of security in model driven development, with a special focus on finding empirical studies. The authors provide an introduction to the major secure MDD initiatives, but the survey shows that there is a lack of empirical work on the topic. The authors conclude that better standardization initiatives and more empirical research in the field is necessary before it can be considered mature.

Potential Applications

Deployable-collapsable structures have many potential applications, ranging from emergency shelters and facilities, through relocatable semi-permanent structures, to space-station components. A new concept of self-stabilized/self-supported “clicking” structures – featuring stable, stress-free states in both deployed and collapsed forms – shows even greater promise. This article highlights the state-of-the-art in the field of deployable-collapsable structures and discusses their advantages and limitations. A unique concept of “clicking” structures is introduced, and its basic capabilities are presented and discussed. Finally future research needs are mapped out.
