Powder-bed-based 3D-printing of function integrated parts (2015)

Purpose – The purpose of this paper is to show a possibility of how new functions can be integrated in parts, created by the powder-bed-based 3D-printing technology. One big advantage of additive manufacturing technologies is the possibility to create function-integrated parts during the manufacturing process. This applies to mechanical functions like movable elements, thermodynamic functions like contour near cooling channels in a part as well as electrical functions like conductive lines and electrical components. Design/methodology/approach – A powder-bed-based 3D-printer is utilized to process polymethyl methacrylate (PMMA) as base material. To enable new functionalities, an automated exhausting mechanism was implemented into the test system. The created cavities can be filled with new components or rather new materials. Findings – Three different approaches are shown in this paper. The first one was the integration of screw nuts to enhance bolted joints compared to threads, directly created in the part. The average tensile strength could be raised from 200 to 430 N/mm. The second approach was the integration of different reinforcement elements like carbon or metallic fibers. Here again a reinforcement of the tensile strength of approximately 27 per cent could be reached. The last approach shows a method to integrate conductive material as well as electrical components in a part to create simple electrical circuits. Originality/value – The paper demonstrates how to extend an additive powder-bed-based technology with a powder-exhausting mechanism. The possibilities of this technology are illustrated by three examples, integrating mechanical as well as electrical functions in a part.

MHC-assortative facial preferences in humans (2005)

Individuals tend to choose mates who are sufficiently genetically dissimilar to avoid inbreeding. As facial attractiveness is a key factor in human mate preference, we investigated whether facial preferences were related to genetic dissimilarity. We asked female volunteers to rate the attractiveness of men from photographs and compared these results with individual genotypes at the major histocompatibility complex (MHC). In contrast to previously reported preferences based on odour, we found a non-significant tendency for women to rate MHC-similar faces as more attractive, suggesting a preference for cues to a self-similar MHC in faces. Further analysis revealed that male faces received higher attractiveness scores when rated by women who were MHC-similar than by MHC-dissimilar women. Although unexpected, this MHC-similar facial preference is consistent with other studies documenting assortative preferences in humans, including for facial phenotype.
Replacing Copper Wires with Carbon Nanotube Wires in Electrical Transformers (2013)

Carbon nanotubes, with their unique physical properties, have the potential to outperform conventionally used electrical wiring metals. Any improvement in this area of technology would be of great importance to industry, the economy, and the environment, as the global need for electrical energy and its efficient transfer and conversion rapidly increases. Carbon nanotube fibers, which are assemblies made purely of carbon nanotubes, can uniquely be used in macroscopic electrical applications including electrical wires and devices where the operation is enabled by these conductors. This paper presents details of the working prototype of an electrical machine, a transformer, where conventional copper wires have been replaced with conducting wires made purely of carbon nanotube fibers.
Platelet aggregation inhibitors. VIII. 2-Thioadenine derivatives. (1977)

<p>Rapid innovations in electronic healthcare and behavior tracking systems are challenging health coaches (dietitians, personal trainers, etc.) to rethink their traditional roles and healthcare practices. At the same time, many current e-coaching systems have been developed without explicitly incorporating the healthcare professionals’ perspective into the design process. In the current paper, we present three consecutive qualitative studies, starting from the health coach’s perspective on successful coaching, progressively zooming in on the potential role and impact of technology as part of the coaching process. Our main finding is that coaches are concerned that introducing technology in the coaching process puts too much emphasis on behavioral information, lowering the attention for the client’s lived experience, while understanding those experiences is key for successful coaching. We summarize our insights in a multi-channel communication model and draw implications for the design of supporting technology in health coaching.</p>
Translation and scale-invariant gesture recognition in complex scenes (2008)

Gestures are a natural means of communication between humans, and also a natural modality for human-computer interaction. Automatic recognition of gestures using computer vision is an important task in many real-world applications, such as sign language recognition, computer games control, virtual reality, intelligent homes, and assistive environments. In order for a gesture recognition system to be robust and deployable in non-laboratory settings, the system needs to be able to operate in complex scenes, with complicated backgrounds and multiple moving and skin-colored objects. In this paper we propose an approach for improving gesture recognition performance in such complex environments. The key idea is to integrate a face detection module into the gesture recognition system, and use the face location and size to make gesture recognition invariant to scale and translation. Our experiments demonstrate the significant advantages of the proposed method over alternative computer vision methods for gesture recognition.
Direct Interval Forecast of Uncertain Wind Power Based on Recurrent Neural Networks (2017)

Interval forecast is an efficient method to quantify the uncertainties in renewable energy production. In this paper, the idea of prediction intervals (PIs) is employed to capture the uncertainty of wind power generation in power systems. The recurrent neural network (RNN) model is proposed to construct PIs with the lower upper bound estimation method, which is a powerful nonparametric forecast approach. In addition, a novel comprehensive cost function with a new PI evaluation index is designed with the purpose of enhancing the model training. To tune the parameters of RNN prediction model, the dragonfly algorithm with a linearly random weight update method is introduced as the optimization tool. The performance of the proposed prediction model is validated by a case study using a real world wind power dataset, and the comparative results show the superiority of the model.
Electron acceleration in helicon sources (1992)

Evidence is given for wave acceleration of primary electrons in a 1 cm radius helicon plasma source. The second root of the dispersion relation is also seen at low B fields. Electrostatic confinement of primaries appears to be important at these small diameters.
Growth and Thermal and Spectral Properties of a New Nonlinear Optical Crystal TmAl<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub> (2005)

Single crystals of the nonlinear optical (NLO) material TmAl3(BO3)4, space group R32, were grown successfully by the top seeded solution growth (TSSG) method for the first time in our laboratory. Morphology analysis reveals that the crystal is a rhombohedron with nine developed faces with the major forms (12̄10), (21̄1̄0), and (112̄0) parallel to the c-axis. Grown crystals were characterized by X-ray powder diffraction (XRD), and second-harmonic generation (SHG) measurements. The two principal coefficients of thermal expansion along (001) and (100) were measured to be 5.33 × 10-6 and 2.46 × 10-6 K-1, respectively. In addition, the large difference of thermal expansion coefficients between the two crystallographic axes was discussed based on the structure of this crystal. Polarized absorption spectra were measured, and the results suggest that the optical properties of the TmAl3(BO3)4 crystal depend greatly on the polarization. This crystal is a promising candidate for NLO materials.
Minimum-effort driven dynamic faceted search in structured databases (2008)

In this paper, we propose minimum-effort driven navigational techniques for enterprise database systems based on the faceted search paradigm. Our proposed techniques dynamically suggest facets for drilling down into the database such that the cost of navigation is minimized. At every step, the system asks the user a question or a set of questions on different facets and depending on the user response, dynamically fetches the next most promising set of facets, and the process repeats. Facets are selected based on their ability to rapidly drill down to the most promising tuples, as well as on the ability of the user to provide desired values for them. Our facet selection algorithms also work in conjunction with any ranked retrieval model where a ranking function imposes a bias over the user preferences for the selected tuples. Our methods are principled as well as efficient, and our experimental study validates their effectiveness on several application scenarios.
Mitral Regurgitation in Early Myocardial Infarction (1992)

Mitral regurgitation in early myocardial infarction is generally clinically "silent," is more common in anterior infarction, is associated with regional dysfunction but not early ventricular dilation or peak enzyme release, and is an important predictor of cardiovascular mortality.
Intact Protein Analysis by MALDI Tandem Time-of-flight Mass Spectrometry (2003)

Direct MS/MS analysis of small, singly charged protein ions by tandem TOFMS is demonstrated for proteins up to a molecular mass of 12 kDa. The MALDI generated singly charged precursor ions form predominantly product ions resulting from metastable fragmentation at aspartyl and prolyl residues. Additional series of C-terminal sequence ions provide in some cases sufficient information for protein identification. The amount of sample required to obtain good quality spectra is in the high femtomolar to low picomolar range. Within this range, MALDI-MS/MS using TOF/TOF TM ion optics provides now the opportunity for direct protein identification and partial characterization without prior enzymatic hydrolysis.

Active thermography data processing for the NDT&E of frescoes (2010)

In this study, a reproduction of Giotto's fresco "Meeting at Golden Gate" containing artificial defects typical of fresco decay was inspected by active infrared thermography. Data was processed using different techniques in order to improve the infrared signature of the defects and to reduce the impact of non-uniform heating and emissivity variations due to the painting's pigments. It is shown that active thermography constitutes an interesting alternative for the in situ inspection of frescoes without impairing their integrity. More research should be carried out to optimize the way that heat is delivered to the surface to improve defect detectability.
CUPSAT: prediction of protein stability upon point mutations (2006)

CUPSAT (Cologne University Protein Stability Analysis Tool) is a web tool to analyse and predict protein stability changes upon point mutations (single amino acid mutations). This program uses structural environment specific atom potentials and torsion angle potentials to predict DeltaDeltaG, the difference in free energy of unfolding between wild-type and mutant proteins. It requires the protein structure in Protein Data Bank format and the location of the residue to be mutated. The output consists information about mutation site, its structural features (solvent accessibility, secondary structure and torsion angles), and comprehensive information about changes in protein stability for 19 possible substitutions of a specific amino acid mutation. Additionally, it also analyses the ability of the mutated amino acids to adapt the observed torsion angles. Results were tested on 1538 mutations from thermal denaturation and 1603 mutations from chemical denaturation experiments. Several validation tests (split-sample, jack-knife and k-fold) were carried out to ensure the reliability, accuracy and transferability of the prediction method that gives >80% prediction accuracy for most of these validation tests. Thus, the program serves as a valuable tool for the analysis of protein design and stability. The tool is accessible from the link http://cupsat.uni-koeln.de.

Evaluation of the near-field injection method at integrated circuit level (2014)

Near-field injection is a promising method in order to induce local faults in integrated circuits. This method can be used for various applications such as electromagnetic attacks on secured circuits or susceptibility investigations. This paper aims at evaluating the ability of near-field scan injection to induce local disturbances in integrated circuits. The study relies on measurements performed by on-chip voltage sensors, which provide an accurate method to characterize the induced voltage fluctuations.
The advantages of evaporative light scattering detection in pharmaceutical analysis by high performance liquid chromatography and supercritical fluid chromatography (1992)

Abstract The evaporative light scattering detector (ELSD) has been used in pharmaceutical analysis by liquid and supercritical fluid chromatography. An ELSD equipped with interchangeable interfaces enables the use of various eluents (UV‐ or non‐UV‐absorbing) in isocratic or gradient mode. Analyses were performed on several non‐UV‐absorbing excipients and active substances. The narrow spread of the response factors of the various compounds investigated has indicated that the detector is suitable for direct raw quantitation of unknown samples in stability studies.
A Facile Method for Detritylation of 5′-O-Dimethoxytrityl-3′-O-<i>tert</i>-butyldimethylsilyl-2′-deoxynucleosides (1994)

Abstract The dimethoxytrityl group can be removed effectively from 5′-O-dimethoxytrityl-3′-O-tert-butyl dimethylsilyl-2′-deoxynucleosides and their N-acyl derivatives by using sulfonated crosslinked (1% DVB) polystyrene in dichloromethane-methanol (97.5 : 2.5,v/v) without causing depurination. It has been observed that solvent and percentage of crosslinking plays important role in these reactions.
A community perspective on air pollution: Industry's near neighbours (1992)

This includes a carbon black factory, an oil refinery, and the largest petrochemical complex in Australia.
Genetic Determinants of Autoimmune Disease and Coronary Vasculitis in the MRL- <i>lpr/lpr</i> Mouse Model of Systemic Lupus Erythematosus (1998)

MRL-lpr/lpr (MRL/lpr) mice are a model of human autoimmune disease. They exhibit a number of characteristics of systemic lupus erythematosus, including anti-DNA Abs, anti-cardiolipin Abs, immune complex-mediated vasculitis, lymphadenopathy, and severe glomerulonephritis. Although the autoimmune disorder is mediated primarily by mutation of the Fas gene (lpr), which interferes with lymphocyte apoptosis, MRL/lpr mice also have other predisposing genetic factors. In an effort to identify these additional factors, we have applied quantitative trait locus (QTL) mapping using an intercross between MRL/lpr mice and the nonautoimmune inbred strain BALB/cJ. A complete linkage map spanning the entire genome was constructed for 189 intercross progeny, and genetic loci contributing to features of the autoimmunity were identified using statistical analytic procedures. As expected, the primary genetic determinant of autoimmune disease in this cross was the Fas gene on mouse chromosome 19, exhibiting a lod score of 60. In addition, two novel loci, one on chromosome 2 (lod score, 4.3) and one on chromosome 11 (lod score, 3.1), were found to contribute to levels of anti-DNA Abs. Interestingly, the chromosome 19 and chromosome 11 QTLs, but not the chromosome 2 QTL, also exhibited associations with anti-cardiolipin Abs (lod scores, 38.4 and 2.6). We further examined the effects of these QTLs on the development of coronary vasculitis in the F2 mice. Our results indicate that the QTLs on chromosomes 11 and 19 also control the development of vasculitis, demonstrating common genetic determinants of autoantibody levels and vasculitis.
A recommendation for high-dose Ara-C interval treatment based on studies in a slow-growing leukemia model (BNML) (1982)

The arabinoside cytosine (Ara-C) dose-response relationship was investigated in a slow-growing rat leukemia (BNML) which is a realistic model for human acute myelocytic leukemia (AML). For both the tumor load reduction determined as leukemic colony-forming units spleen (LCFU-s) and the normal stem cell toxicity determined as colony forming units spleen (CFU-s), a plateau curve was observed. Maximum LCFU-s reduction was observed after high-dose Ara-C (200 mg/kg), while the greatest CFU-s reduction occurred following a ten fold lower dose. For the high Ara-C dose, several methods of administration were compared: rapid intravenous (IV), intramuscular, subcutaneous, intraperitoneal, and continuous infusion. The most effective tumor load reduction was obtained by rapid IV interval treatment. In addition, rapid IV interval administration of Ara-C was less toxic to normal bone marrow stem cells than continuous infusion of the drug. The results of these studies may justify the application of high-dose Ara-C interval treatment in human AML.
Sensitivity to basis mismatch of compressed sensing for spectrum analysis and beamforming (2009)

Compressed sensing theory suggests that successful inversion of an image of the physical world from its modal parameters can be achieved at measurement dimensions far lower than the image dimension, provided that the image is sparse in an a priori known basis. The assumed basis for sparsity typically corresponds to a gridding of the parameter space, e.g., an DFT grid in spectrum analysis. However, in reality no physical field is sparse in the DFT basis or in an a priori known basis. No matter how finely we grid the parameter space the sources may not lie in the center of the grid cells and there is always mismatch between the assumed and the actual bases for sparsity. In this paper, we study the sensitivity of compressed sensing (basis pursuit to be exact) to mismatch between the assumed and the actual sparsity bases. Our mathematical analysis and numerical examples show that the performance of basis pursuit degrades considerably in the presence of basis mismatch. Index Terms — Compressed sensing, image inversion, image reconstruction, sensitivity to basis mismatch, sparse recovery. 1.
Lipoprotein lipase. (1977)

The activity of lipoprotein lipase in the vascular bed represents the major pathway by which triglyceride fatty acid is cleared from the plasma and made available to the epripheral tissues. Recent studies on the properties of the enzyme, both solubilized and membrane-bound have provided new information on the regulation of its activity with the major triglyceride-rich lipoprotein substrates. A key role for this enzyme in the regulation of plasma triglyceride levels is indicated from studies of lipase levels in human adipose tissue and in blood plasma obtained after injection of heparin.
The Falling Rate of Positive Penicillin Skin Tests from 1995 to 2007 (2009)

There has been a steady decline in the proportion of positive PenST results between 1995 and 2007, independent of study subject age and TSR. Increasing age and increasing TSR were associated with a lower rate of positive PenST results.
Lycopene cyclase paralog CruP protects against reactive oxygen species in oxygenic photosynthetic organisms (2012)

In photosynthetic organisms, carotenoids serve essential roles in photosynthesis and photoprotection. A previous report designated CruP as a secondary lycopene cyclase involved in carotenoid biosynthesis [Maresca J, et al. (2007) Proc Natl Acad Sci USA 104:11784-11789]. However, we found that cruP KO or cruP overexpression plants do not exhibit correspondingly reduced or increased production of cyclized carotenoids, which would be expected if CruP was a lycopene cyclase. Instead, we show that CruP aids in preventing accumulation of reactive oxygen species (ROS), thereby reducing accumulation of β-carotene-5,6-epoxide, a ROS-catalyzed autoxidation product, and inhibiting accumulation of anthocyanins, which are known chemical indicators of ROS. Plants with a nonfunctional cruP accumulate substantially higher levels of ROS and β-carotene-5,6-epoxide in green tissues. Plants overexpressing cruP show reduced levels of ROS, β-carotene-5,6-epoxide, and anthocyanins. The observed up-regulation of cruP transcripts under photoinhibitory and lipid peroxidation-inducing conditions, such as high light stress, cold stress, anoxia, and low levels of CO(2), fits with a role for CruP in mitigating the effects of ROS. Phylogenetic distribution of CruP in prokaryotes showed that the gene is only present in cyanobacteria that live in habitats characterized by large variation in temperature and inorganic carbon availability. Therefore, CruP represents a unique target for developing resilient plants and algae needed to supply food and biofuels in the face of global climate change.
