Sample size planning for classification models
In biospectroscopy, suitably annotated and statistically independent samples (e. g. patients, batches, etc.) for classifier training and testing are scarce and costly. Learning curves show the model performance...
PublikationenResults of Measuring the Influence of Casimir Energy on Superconducting Phase Transitions
The ALADIN experiment aims at observing how the critical magnetic field of a superconducting aluminum film is modified, when it constitutes one of the reflecting surfaces of a Casimir cavity. If successful,...
PublikationenThe effect of high-pressure synthesis on flux pinning in MgB2-based superconductors
Increasing the pressure during manufacturing MgB2 enhances the volume pinning force and moves the position of the maximum to higher magnetic fields. A similar shift was observed when Ti or SiC was added...
PublikationenBroadband, diode pumped Yb:SiO2 multicomponent glass laser
Fabrication, spectroscopic properties and laser performance of a Yb:SiO2 multicomponent glass have been investigated in this paper. The glass system comprising of SiO2, Al2O3 and La2O3 excels in terms...
PublikationenNanoscopic Tip Sensors Fabricated by Gas Phase Etching of Optical Glass Fibers
Silica-based fiber tips are used in a variety of spectroscopic, micro- or nano-scopic optical sensor applications and photonic micro-devices. The miniaturization of optical sensor systems and the technical...
PublikationenNext generation of a sub-millimetre wave security camera utilising superconducting detectors
Based on the previously demonstrated concept of passive security screening utilising superconducting detectors, a next generation camera was developed to meet application demands. The new system was designed...
PublikationenLifetime improvement of micro-fabricated alkali vapor cells by atomic layer deposited wall coatings
Alumina (Al2O3), silicon dioxide (SiO2) and titanium dioxide (TiO2) films were examined for their suitability as a protection coating for micro-fabricated cesium vapor cells. The layers were deposited...
PublikationenHighly p-doped regions in silicon solar cells quantitatively analyzed by small angle bevelling and micro-Raman spectroscopy
Highly p-doped regions in multicrystalline silicon solar cells, such as the back surface field region, are analyzed by means of small angle beveling and micro-Raman spectroscopy. Small angle beveling and...
PublikationenSuperconducting niobium nitride thin films deposited by metal organic plasma-enhanced atomic layer deposition
Superconducting NbN¬x thin films were deposited by plasma enhanced-atomic layer deposition (PE-ALD) using the metal organic precursor (tert-butylimido)-tris (diethylamino)-niobium (TBTDEN) and hydrogen...
PublikationenNon-invasive imaging of intracellular lipid metabolism in macrophages by Raman microscopy in combination with stable isotopic labeling
Monocyte-derived macrophages play a key role in atherogenesis because their transformation into foam cells is responsible for deposition of lipids in plaques within arterial walls. The appearance of cytosolic...
