1 Einleitung (2019)

In vielen technischen Anwendungen ist zur Verbesserung der Energieeffizienz die Reibung in Wälzlagerungen zu reduzieren. Wälzlager, die hohen Zentripetalbeschleunigungen ausgesetzt sind, können eine stark erhöhte Reibung an den Käfigkontakten aufweisen, da der bordgeführte Käfig gegen den Außenring gedrückt und verformt wird. Zur gezielten Entwicklung neuer reibungsarmer Lagerlösungen ist in solchen Anwendungsfällen sowohl die Schmierstoffhydrodynamik in den Käfigkontakten als auch die Käfigelastizität in der Wälzlagerdynamiksimulation zu berücksichtigen. Die Berücksichtigung der Schmierstoffhydrodynamik erfolgt mit Hilfe analytischer Berechnungsansätze differenziert für jeden Käfigkontakt. Die Kontaktberechnung bleibt damit weiterhin recheneffizient, numerisch stabil und für die Dynamiksimulation von Wälzlagern geeignet. Eine Umsetzung dieses Ansatzes erfolgt im Wälzlagerdynamiksimulationsprogramm CABA3D. Eine ausreichend hohe Genauigkeit der hy...
Cytoplasmic and Nuclear Estradiol and Progesterone Receptors in Human Endometrium* (1978)

Estradiol and progesterone receptors have been characterized in normal human endometrial biopsy samples. The cytosol and nuclei were prepared from 150-250-mg samples, either processed immediately or kept in liquid nitrogen. The total concentration of estradiol-and progesterone-binding sites (available or occupied with endogenous hormone) were measured in both fractions. Results were best expressed in femto-moles per mg DNA, or in sites per cell, assuming an even distribution of receptor throughout the endometrial samples. The contribution to total binding of non-saturable binding components and of plasma proteins (transcortin or sex steroid-binding protein) was taken into account. Measurements were obtained in more than 300 patients, among whom 54 had completely normal menstrual cycles on the basis of clinical, hormonal, and histological features. Total estradiol and progesterone receptors were highest in the late proliferative phase (about 8,000 and 12,000 sites/cell, respectively) and were very significantly lower in the late secretory phase. During the proliferative phase, estradiol receptors were increased only in the nuclear fraction, whereas progesterone receptors were increased mainly in the cytoplasm. In the early luteal phase, estradiol and progesterone receptors decreased in the cytosol, whereas they remained high in the nuclei. Both receptors were at their lowest level in cytosol and nuclei in the late secretory phase. The changes of total estradiol and progesterone receptor sites and of their respective subcellular distributions seem to depend upon the plasma levels of both hormones and to follow the same cause and effect relationships as those demonstrated experimentally in laboratory animals.
Pupil Dilation Uncovers Extra Listening Effort in the Presence of a Single-Talker Masker (2011)

To maintain similar intelligibility levels, participants needed more mental effort for speech perception in the presence of a single-talker masker and then with the two other types of maskers. This suggests an additive interfering effect of speech information from the single-talker masker. The dissociation between these performance and mental effort measures underlines the importance of including measurements of pupil dilation as an independent index of mental effort during speech processing in different types of noisy environments and at different intelligibility levels.

Virtual environments for geographic visualization (1999)

Virtual environment (VE) technologies have considerable potential to extend the power of information visualization methods, and those of scientific visualization more broadly. Our specific focus here is on VE technologies as a medium for geographic visualization and on some of the challenges that must be addressed if the potential of VE is to be realized in this context.
Adaptive soft molecular self-assemblies (2015)

Adaptive molecular self-assemblies provide possibility of constructing smart and functional materials in a non-covalent bottom-up manner. Exploiting the intrinsic properties of responsiveness of non-covalent interactions, a great number of fancy self-assemblies have been achieved. In this review, we try to highlight the recent advances in this field. The following contents are focused: (1) environmental adaptiveness, including smart self-assemblies adaptive to pH, temperature, pressure, and moisture; (2) special chemical adaptiveness, including nanostructures adaptive to important chemicals, such as enzymes, CO2, metal ions, redox agents, explosives, biomolecules; (3) field adaptiveness, including self-assembled materials that are capable of adapting to external fields such as magnetic field, electric field, light irradiation, and shear forces.
Gel formation in a mixture of a block copolymer and a nematic liquid crystal (2011)

The viscoelastic properties of a binary mixture of a mesogenic side-chain block copolymer in a low molecular weight nematic liquid crystal are studied for mass concentrations ranging from the diluted regime up to a liquid crystalline gel state at about 3%. In the gel state, the system does not flow, exhibits a polydomain structure on a microscopic level, and strongly scatters light. Below the gelation point, the system is homogeneous and behaves like a usual nematic, so the continuum theory of liquid crystals can be applied for interpreting the experimental data. Using the dynamic Fréedericksz transition technique, the dependence of the splay elastic constant and the rotational viscosity on the polymer concentration have been obtained. Comparing the dynamic behavior of block copolymer solutions with the respective homopolymer solutions reveals that, above a mass concentration of 1%, self-assembling of the block copolymer chain segments in clusters occurred, resulting in a gel state at higher concentrations. The effective cluster size is estimated as a function of the concentration, and a scaling-law behavior near the sol-gel transition is confirmed. This technique may serve as an alternative method for determining the gelation point.
The New Concept of Development in China Modernization (2004)

Modernization is the only way of human social progress and civilized development China have carried out socialist modern way with its own character The Five plan as a whole have particularly showed the way of China modernization: it not only confirms the success of modernization in our country during the initial stage, but also bravely envisages the present challenges and difficulties, and it is also guidelines to make modernization walk up to high steps
A Novel Microstrip to Coplanar Waveguide Transition for Flip-Chip Interconnection using Electromagnetic Coupling (1998)

A novel compact microstrip to coplanar waveguide (CPW) transition is proposed for flip-chip interconnection. Broadband performance of the transition is simulated and agrees well with measured results. A good interconnection between microstrip line on a motherboard to CPW on a flip-chip is accomplished without any vias. For 10dB return loss, the microstrip-to-CPW transition and the microstrip-to-flip-chip interconnection present 170% and 140% bandwidth, respectively.
Attachment sites for bacteriophage P2 on the Escherichia coli chromosome: DNA sequences, localization on the physical map, and detection of a P2-like remnant in E. coli K-12 derivatives (1992)

Integration of bacteriophage P2 into the Escherichia coli genome involves recombination between two attachment sites, attP and attB, one on the phage and one on the host genome, respectively. At least 10 different attB sites have been identified over the years. In E. coli C, one site, called locI, is preferred, being occupied before any of the others. In E. coli K-12, no such preference is seen (reviewed in L. E. Bertani and E. W. Six, p. 73-143, in R. Calendar, ed., The Bacteriophages, vol. 2, 1988). The DNA sequence of locI has been determined, and it shows a core sequence of 27 nucleotides identical to attP (A. Yu, L. E. Bertani, and E. Haggård-Ljungquist, Gene 80:1-12, 1989). By inverse polymerase chain reactions, the prophage-host junctions of DNA extracted from P2 lysogenic strains have been amplified, cloned, and sequenced. By combining the attL and attR sequences, the attB sequences of locations II, III, and H have been deduced. The core sequence of location II had 20 matches to the 27-nucleotide core sequence of attP; the sequences of locations III and H had 17 matches. Thus, the P2 integrase accepts at least up to 37% mismatches within the core sequence. The E. coli K-12 strains examined all contain a 639-nucleotide-long cryptic remnant of P2 at a site with a sequence similar to that of locI but that may have a different map position. The P2 remnant consists of the C-terminal part of gene D, all of gene ogr, and attR. Locations II, III, and H have been located on Kohara's physical map to positions 3670, 1570 to 1575, and 2085, respectively.

[Comparison of the efficacy of ivermectin in injectable form and as a paste in horses]. (1985)

A comparison was made of the efficacy of Ivermectin administered as an injection and as a paste. Fourteen horses which were naturally infected with small strongyles were divided into three groups. Animals of group 1 received an injection of 5 ml Ivermectin, equivalent to 500 kg bodyweight, horses of group 2 received one injector with Ivermectin as a paste (for 500 kg body weight), a third group remained untreated as a control. Faecal examinations and larval cultures on the day of treatment and 14, 28 and 42 days later showed that both injection and paste had a 100 percent efficacy against mature and immature small strongyles in these horses.
Rosemary extracts in functional foods: extraction, chemical characterization and incorporation of free and microencapsulated forms in cottage cheese (2016)

Consumers search for food with functional characteristics beyond its nutritional properties. Thus, the concept of functional food has become a hot topic, allowing us to obtain additional health benefits, including disease prevention. In this context, plants are recognized as sources of a wide range of bioactives, including phenolic compounds. Herein, rosemary aqueous extract was used as a functional ingredient for cottage cheese, after proving that it possesses both higher content of phenolic compounds and antioxidant activity, comparatively with the corresponding hydroethanolic extract. However, a decrease of bioactivity was observed for the cheese samples enriched with the extracts in free form after seven days under storage. Therefore, in order to preserve the antioxidant activity, the rosemary aqueous extract was efficiently microencapsulated by using an atomization/coagulation technique. Overall, the introduction of both free and microencapsulated extracts provided bioactivity that was better preserved with microencapsulated extracts without changing the nutritional value of cottage cheese.
Subscription summaries for scalability and efficiency in publish/subscribe systems (2003)

A key issue when designing and implementing largescale publish/subscribe systems is how to efficiently propagate subscriptions among the brokers of the system. Brokers require this information in order to forward incoming events only to interested users, filtering out unrelated events, which can save significant overheads (particularly network bandwidth and processing time at the brokers). In this paper we contribute the notion of subscription summaries, a mechanism appropriately compacting subscription information. We develop the associated data structures and matching algorithms. The proposed mechanism can handle event/subscription schemata that are rich in terms of their attribute types and powerful in terms of the allowed operations on them. Our major results are that the proposed mechanism (i) is scalable, with the bandwidth required to propagate subscriptions increasing only slightly, even at huge-scales, and (ii) is significantly more efficient, up to orders of magnitude, depending on the scale, with respect to the bandwidth requirements for propagating subscriptions.
Reactions of $\gamma$,$\gamma$,$\gamma$-Trichloroethylidene-m-Nitroacetophenone with Hydrazines (1973)

2,6-Disubstituted-3-pyridazinones were synthesized by the reactions of ,,-trichloroethylidene-m-nitroacetophenone with phenylhydrazine and substituted phenylhydrazines, and hydrazone was isolated as an intermediate from the reaction with 2, 4-dinitrophenylhydrazine. From the reaction with hydrazine hydrate 3-(m-nitrophenyl)-5-trichloromethyl-2-pyrazoline was obtained in good yield. The effect of substituents on phenyl group in the reaction of ,,-trichloroethylidene-m-nitroacetophenone with substituted phenylhydrazines was also discussed.
Modulation properties of a near travelling-wave semiconductor laser amplifier (1992)

The amplitude and phase or frequency modulation properties for pump current modulation of a near travelling-wave semiconductor laser amplifier are examined. The investigations are performed numerically in the time domain with large-signal analysis and in the frequency domain with small-signal analysis. It is shown that the modulation bandwidth is increased by high pump current or high input power and that the small-signal modulation efficiency is increased by low pump current or low input power. The validity of the simulations is supported by experimental results.
Toward prediction of physiological state signals in sleep apnea (1998)

A recurrent connectionist model is described to predict dynamic respiratory state in the apneic sleeping patient. The time-domain model of nonlinear time-lagged interactions between heart rate, respiration, and oxygen saturation was developed to implicitly embed the dynamics of the respiration and cardiovascular control systems. Multiple future time scales were enforced on the network during training to explore the limits of the prediction horizon and produce a global representation of dynamic state trajectory. Predicted apneic respiration state results are presented in terms of invariant geometric statistics (largest Lyapunov exponent lambda L and correlation dimension Dc). The lambda L prediction error was 13%, while Dc error was within 9% of the true time series value. The magnitude of these errors may fall within experimental noise levels. This methodology may eventually be useful in dynamic control of continuous positive airway pressure (CPAP) therapy devices, and may lead to increased patient compliance with this therapy.
Effect of mineral oil, sunflower oil, and coconut oil on prevention of hair damage. (2003)

Previously published results showed that both in vitro and in vivo coconut oil (CNO) treatments prevented combing damage of various hair types. Using the same methodology, an attempt was made to study the properties of mineral oil and sunflower oil on hair. Mineral oil (MO) was selected because it is extensively used in hair oil formulations in India, because it is non-greasy in nature, and because it is cheaper than vegetable oils like coconut and sunflower oils. The study was extended to sunflower oil (SFO) because it is the second most utilized base oil in the hair oil industry on account of its non-freezing property and its odorlessness at ambient temperature. As the aim was to cover different treatments, and the effect of these treatments on various hair types using the above oils, the number of experiments to be conducted was a very high number and a technique termed as the Taguchi Design of Experimentation was used. The findings clearly indicate the strong impact that coconut oil application has to hair as compared to application of both sunflower and mineral oils. Among three oils, coconut oil was the only oil found to reduce the protein loss remarkably for both undamaged and damaged hair when used as a pre-wash and post-wash grooming product. Both sunflower and mineral oils do not help at all in reducing the protein loss from hair. This difference in results could arise from the composition of each of these oils. Coconut oil, being a triglyceride of lauric acid (principal fatty acid), has a high affinity for hair proteins and, because of its low molecular weight and straight linear chain, is able to penetrate inside the hair shaft. Mineral oil, being a hydrocarbon, has no affinity for proteins and therefore is not able to penetrate and yield better results. In the case of sunflower oil, although it is a triglyceride of linoleic acid, because of its bulky structure due to the presence of double bonds, it does not penetrate the fiber, consequently resulting in no favorable impact on protein loss.
Effects of short-term administration of cytidine, uridine and levoglutamine, alone or in combination, on the cerebral electrical activity of patients with chronic cerebrovascular disease. (1988)

Various data in the literature confirm that spectral analysis by an electroencephalograph (EEG) allows the evaluation and quantification of the modifications of cerebral electrical activity due to pathological events or to drugs acting on the central nervous system. Thirty patients with chronic cerebrovascular disease, selected according to the criteria established by the 1980 Paris Ad Hoc Committee were submitted to EEG analysis in basal conditions and after intravenous short-term administration of various doses of cytidine, uridine and levoglutamine given either alone or in combination. The combined administration of the three substances led to a general improvement of cerebral electrical parameters with a trend toward more physiological patterns.
Characterization of Branched Polymers by Size Exclusion Chromatography with Light Scattering Detection (1980)

Size exclusion chromatography (SEC) separates molecules of a polymer sample on the basis of hydrodynamic volume. When the chromatograph is equipped only with a concentration-sensitive detector, i.e. conventional SEC, a molecular weight distribution (MWD) can be obtained from the chromatogram only through use of a calibration function relating molecular weight and elution volume V (1). The calibration technique used in conventional SEC does not always give the correct MWD, however. The molecular size of a dissolved polymer depends on its molecular weight, chemical composition, molecular structure, and experimental parameters such as solvent, temperature, and pressure (2). If the polymer sample and calibration standards differ in chemical composition, the two materials probably will feature unequal molecular size/weight relationships. Such differences also will persist between branched and linear polymers of identical chemical composition. Consequently, assumption of the same molecular weight/V relation for dissimilar calibrant and sample leads to transformation of the sample
Advanced glycation endproduct modified basement membrane attenuates endothelin-1 induced [Ca2+]i signalling and contraction in retinal microvascular pericytes. (2004)

These results suggest that substrate derived AGE crosslinks can influence RMP physiology by mechanisms which include disruption of ETA receptor signalling. AGE modification of vascular BMs may contribute to the retinal hemodynamic abnormalities observed during diabetes.
Shallow diffusion of zinc into InAs and InAsSb (1988)

Elemental zinc was diffused using the close-tube method into InAs and InAs1−xSbx solid solution (x=0.10–0.12). All the samples were (100) oriented. The diffusion temperatures were 500, 400, and 350 °C. Shallow junction depths (∼1 μm) were obtained. The temperature dependence of the effective diffusion coefficient of zinc is described by the formula: D=1.6×10−4 exp(−1.07/kT). The mean concentration of zinc for diffused layers at 500 °C is 3×1019 atoms cm−3. Diffused p+n diodes showing good electrical characteristics at 77 K were prepared at 350 °C from the n-InAsSb/n+GaSb system.
Adaptive Systems in Pattern Recognition (1963)

The perceptual superiority of the human visual system over automata is outlined comparing the properties of both systems. The most effective property with regard to pattern recognition is the internal adaptability and the ability of abstracting. Both properties are well performed by human beings. A mechanical perceptor for complex pattern recognition must also have these capabilities. The use of adaptation for pattern recognition is discussed. The realization of these properties by machines is difficult, especially the development of an adequate feature generator which performs the internal adaptability and thus solves the problem of identification-criteria invariance of patterns. This is assumed to be the main task in pattern recognition research. External teaching processes may be accomplished by adaptive categorizers. The existing classification methods are outlined and discussed with regard to adaptive systems. Adaptive categorizers of a learning matrix type and a perceptron type are compared as to structure, linear classification performance, and training routine. It is assumed, however, that the somewhat passive external adaptation of categorizers must be supplemented by a more active adaptation by the system itself.
