The St. Pölten University of Applied science was founded in 1993 and has approximately 1,600 students enrolled. It currently offers 14 degree programmes.Study opportunities comprise degree programmes and continuing education courses in the fields of Health and Social science, Business, and Technology. These courses are both academically and vocationally oriented and include training in business administration, law, foreign languages, and interpersonal skills.Students can choose to acquire international certificates, such as those offered by Cisco, Microsoft, and Cambridge. Work placements seek to ensure that they gain hands-on experience in the workplace before graduation.Teaching is by lectures, laboratory work and small tutorial groups. Students carry out practical work and team projects. Among the facilities of the university are a library, state-of-the art video, computer, network and multimedia laboratories, and satellite equipment. The students run their own radio station, Campus Radio 94.4. Wikipedia.

With formidable recent improvements in data processing and information retrieval, knowledge discovery/data mining, business intelligence, content analytics and other upcoming empirical approaches have an enormous potential, particularly for the data intensive biomedical sciences. For results derived using empirical methods, the underlying data set should be made available, at least during the review process for the reviewers, to ensure the quality of the research done and to prevent fraud or errors and to enable the replication of studies. However, in particular in the medicine and the life sciences, this leads to a discrepancy, as the disclosure of research data raises considerable privacy concerns, as researchers have of course the full responsibility to protect their (volunteer) subjects, hence must adhere to respective ethical policies. One solution for this problem lies in the protection of sensitive information in medical data sets by applying appropriate anonymization. This paper provides an overview on the most important and well-researched approaches and discusses open research problems in this area, with the goal to act as a starting point for further investigation. © Springer-Verlag Berlin Heidelberg 2014.

Magnetic vortex core reversal of a 20-nm-thick permalloy disk with a diameter of 100nm was studied by micromagnetic simulations. By applying a global out-of-plane magnetic field pulse, it turned out that the final core polarity is very sensitive to pulse width and amplitude, which makes it hard to control. The reason for this phenomenon is the excitation of radial spin waves, which dominate the reversal process. The excitation of spin waves can be strongly suppressed by applying a local field pulse within a small area at the core center. With this approach, ultra-short reversal times of about 15 ps were achieved, which are ten times faster compared to a global pulse. © 2014 AIP Publishing LLC. Source

Background: A range of scaffolds is available from various manufacturers for cartilage repair through matrix-associated autologous chondrocyte transplantation (MACT), with good medium- to long-term results. Purpose: To evaluate clinical and magnetic resonance imaging (MRI) outcomes 2 years after MACT on the knee joint using the Novocart 3D scaffold based on a bilayered collagen type I sponge. Study Design: Case series; Level of evidence, 4. Methods: Of 28 initial patients, 23 were clinically and radiologically evaluated 24 months after transplantation. Indications for MACT were chondral or osteochondral lesions on the knee joint with a defect size >2 cm2, no instability, and no malalignment (axis deviation <5°). Then, MRI was performed on a 3-T scanner to assess the magnetic resonance observation of cartilage repair tissue (MOCART) and 3-dimensional (3D) MOCART scores. A variety of subjective scores (International Knee Documentation Committee [IKDC], Knee injury and Osteoarthritis Outcome Score [KOOS], Noyes sports activity rating scale, Tegner activity scale, and visual analog scale [VAS] for pain) were used for clinical evaluation. Results: Two years after MACT, the MRI evaluation showed a mean MOCART score of 73.2 ± 12.4 and a 3D MOCART score of 73.4 ± 9.7. Clinical results showed mean values of 69.8 ± 15.2 for the IKDC; 51.6 ± 21.2, 86.5 ± 13.9, 54.5 ± 23.6, 65.0 ± 8.0, and 91.5 ± 10.6 for the KOOS subscales (Quality of Life, Pain, Sports and Recreation, Symptoms, and Activities of Daily Living, respectively); 77.5 ± 12.7 for the Noyes scale; 4.4 ± 1.6 for the Tegner activity scale; and 1.8 ± 1.7 for the VAS, with statistically significant improvement in all scores other than KOOS-Symptoms. Conclusion: Undergoing MACT using the Novocart 3D scaffold is an applicable method to treat large focal chondral and osteochondral defects, with good short-term clinical and radiological results. © 2014 The Author(s).

Micromagnetic simulations of magnetization reversals of Nd-Fe-B anisotropic magnets with exchange-coupled grains demonstrate that the local demagnetization factor decreases as the grain size is reduced. This explains the higher coercivity and the lower temperature dependence of coercivity in magnets with smaller grain sizes. When a fraction of Nd2Fe14B grains become a single domain state for average grain sizes <1 μm, a higher magnetic field is needed to magnetize them, giving rise to a two-step initial magnetization curve. © 2014 Acta Materialia Inc.

Planar magnetic nanowires have been vital to the development of spintronic technology. They provide an unparalleled combination of magnetic reconfigurability, controllability, and scalability, which has helped to realize such applications as racetrack memory and novel logic gates. Microfabricated atom optics benefit from all of these properties, and we present the first demonstration of the amalgamation of spintronic technology with ultracold atoms. A magnetic interaction is exhibited through the reflection of a cloud of 87Rb atoms at a temperature of 10 μK, from a 2 mm × 2 mm array of nanomagnetic domain walls. In turn, the incident atoms approach the array at heights of the order of 100 nm and are thus used to probe magnetic fields at this distance. © 2012 American Chemical Society. Source
