AUSWIRKUNGEN DER VERKÜRZTEN MITTELSTUFE (G8) AUF AUSGEWÄHLTE SCHULISCHE UND AUSSERSCHULISCHE MERKMALE DER LEBENSWELT VON KINDERN UND JUGENDLICHEN (2015)

Die ZSF verfolgt das Anliegen, die wissenschaftlichen Diskurse zu den Phänomenen Bewegung, Spiel und Sport in den Perspektiven von Erziehung, Bildung, Sozialisation und Unterricht zu erschließen und zu fördern. Dafür soll nicht die Festlegung auf ein bestimmtes inhaltliches oder forschungsmethodisches Paradigma bestimmend sein, sondern gedankliche Beweglichkeit, konstruktiver Dialog, fruchtbare Entwicklung und Reflexion von Theorie und Empirie. In das Blickfeld können dabei alle Abschnitte des Lebenslaufs und alle Praxisfelder von Sport- und Bewegungskultur geraten, in denen pädagogische Fragestellungen eine Rolle spielen (z. B. Schulsport, Vereinssport, Selbstorganisierter Sport etc.). Die Vielfalt sportpädagogischer Forschungsthemen und -ausrichtungen soll so – orientiert an wissenschaftlicher Substanz und gesellschaftlicher Relevanz – ein offenes Forum erhalten, Entwicklungen zu beschreiben, zu analysieren und zu erörtern, sie kritisch zu hinterfragen oder auch zukunftsbezogen zu modellieren.
Association between the pancreas transplantation and survival of patients with diabetes: A single center experience (2017)

Pancreas transplantation is considered a therapeutic option for patients with complicated diabetes mellitus. In this study, we compared survival rate between patients on the waiting list for pancreas transplant alone(PTA), simultaneous pancreas-kidney(SPK) transplant, and pancreas after kidney(PAK) transplant and transplant recipients. A total of 503 patients (PTA:n = 116; SPK:n = 303; PAK:n = 84) and 280 PT recipients (PTA:n = 89; SPK:n = 155; PAK:n = 36) were retrospectively analyzed at our center between February 2000 and December 2015; 11.9%(60/503) of the patients on the waiting list and 4.3%(12/280) of the PT recipients died. The overall survival rate was higher in the waiting list group for the first year (99.3% vs. 97.8%), after which it was significantly higher in PT group (p = 0.039). The overall relative risk of all-cause mortality for transplant recipients was 2.145(p = 0.285) for PTA, 0.688(p = 0.735) for PAK, however,0.361 (p = 0.012) for SPK compared with that for the waiting list patients. SPK transplant recipients had considerable higher survival benefits, despite the relatively long waiting period, especially after 1 year. In addition, PTA and PAK can also be considered as a treatment option as patient survival was not poor.
Stable and robust nanotubes formed from self-assembled polymer membranes (2006)

We create long polymer nanotubes by directly pulling on the membrane of polymersomes using either optical tweezers or a micropipette. The polymersomes are composed of amphiphilic diblock copolymers and the nanotubes formed have an aqueous core connected to the aqueous interior of the polymersome. We stabilize the pulled nanotubes by subsequent chemical cross-linking. The cross-linked nanotubes are extremely robust and can be moved to another medium for use elsewhere. We demonstrate the ability to form networks of polymer nanotubes and polymersomes by optical manipulation. The aqueous core of the polymer nanotubes together with their robust character makes them interesting candidates for nanofluidics and other applications in biotechnology.
Epithelioid Hemangioendothelioma of Skin and Soft Tissues: Clinicopathologic and Immunohistochemical Study of 30 Cases (1997)

Epithelioid hemangioendothelioma of soft tissues (EHE) represents a distinct entity with an unpredictable clinical course. We analyzed the clinicopathologic and immunohistochemical features in a series of 30 patients. Patient age range was 16-74 years (median 50); 18 of 30 patients were female. Eight tumors arose in the lower and two in the upper extremities, seven on the trunk, five each in the head/ neck and anogenital regions, two in the mediastinum, and one in the abdomen. Seventeen neoplasms were located in deep soft tissues, nine were subcutaneous or perifascial, and four were dermal; size ranged from 0.4 to 10 cm; in 11 cases the tumor was > 5 cm. Tumors with an infiltrative growth pattern were more common than entirely circumscribed lesions. The tumors were composed histologically of short strands, cords, or small clusters of epithelioid, round, to slightly spindled endothelial cells that formed at least focally, intracellular lumina and were set in a frequently myxohyaline stroma. Thirteen of 30 lesions showed angiocentric growth, which was occlusive in many cases. Immunohistochemically, all cases tested were positive for at least one endothelial marker (CD31, CD34, factor VIII, Ulex europaeus), six of 23 (26%) were positive for cytokeratin, and five of 11 (45%) were positive for alpha-smooth muscle actin. Median follow-up of 36 months (range 2-96) in 24 cases showed local recurrence in three cases and systemic metastases in five cases (21%); four patients (17%) died of tumor. Although more aggressive histologic features (striking nuclear atypia in eight cases, numerous spindled cells in 10, more than two mitoses per 10 high-power fields in nine, and small, more solid angiosarcomalike foci in four cases) tended to be related to poor clinical outcome, there was no clear correlation. Two metastasizing cases showed no histologically atypical features whatever. We suggest that EHE of soft tissue is better regarded as a fully malignant, rather than borderline, vascular neoplasm, albeit the prognosis is better than in conventional angiosarcoma.
The role of radiology in fatality investigations (1988)

Experience at the Armed Forces Institute of Pathology (AFIP) and other centers indicates an important role for radiology in forensic medicine, especially in identification of mass fatality victims [1 -3]. Identification is important for rapidly releasing remains to families and for insurance and legal purposes. Identification also is needed to determine the 10cation of victims within a fatal environment for the study of injury mechanisms with the goal of improved safety design and disaster prevention [4-1 0]. In an emergency, a general radiologist may be asked to aid a multidisciplinary investigation team directed by a forensic specialist. Improvisation in this setting leads to similar techniques being reinvented in seemingly dissimilar situations. Radiologic demonstration of trauma and foreign bodies, especially bullet fragments, which may not be evident on external examination or routine autopsy, is well established [7, 1 1 -1 6]. Radiographic identification of individual bodies has received sporadic attention [17-26], and radiology was first used in a mass disaster investigation in 1949 [27]. Our experience is based largely on investigations of aviation accidents, but the lessons learned are applied readily to other mass disasters as well as to smaller-scale events and to individual fatalities.

Thromboxane A2/Prostaglandin H2 Receptor Activation Mediates Angiotensin II–Induced Postischemic Neovascularization (2005)

Endogenous activation of TXA2 receptor by eicosanoids did not modulate spontaneous neovascularization in the setting of ischemia. Conversely, TXA2 signaling is involved in Ang II-induced AT1-dependent vessel growth.
Testing of a 1.25-m HTS Cable Made from YBCO Tapes (2004)

Ultera and Oak Ridge National Laboratory (ORNL) have jointly designed, built, and tested a 1.25‐m‐long, prototype high‐temperature superconducting (HTS) power cable made from 1‐cm‐wide, second‐generation YBa2Cu3Ox (YBCO)‐coated conductor tapes. Electrical tests of this cable were performed in boiling liquid nitrogen at 77 K. DC testing of the 1.25‐m cable included determination of the V‐I curve, with a critical current of 4200 A. This was consistent with the properties of the 24 individual YBCO tapes. AC testing of the cable was conducted at currents up to 2500 Arms. The ac losses were measured calorimetrically by measuring the response of a calibrated temperature sensor placed on the former and electrically by use of a Rogowski coil with a lock‐in amplifier. AC losses of about 2 W/m were measured at a cable ac current of 2000 Arms. Overcurrent testing was conducted at peak current values up to 12 kA for pulse lengths of 0.1–0.2 s. The cable temperature increased to 105 K for a 12 kA, 0.2 s overcurrent pulse, and the cable showed no degradation after the sequence of overcurrent testing. This commercial‐grade HTS cable demonstrated the feasibility of second‐generation YBCO tapes in an ac cable application.
System Performance of an LTE-A Cellular Network with Shared Relays under Different Resource Demands (2014)

In this paper, we focus on a shared relay architecture in the cellular network instead of deploying multiple separated relays near cell edges. The advantage of shared relaying is the joint processing of signals at the relay to suppress the inter-cell interference (ICI). The performance of a relay enhanced cellular system depends significantly on the resource allocation scheme, especially when taking into account the resource competition from different links. Therefore, in this work, an efficient and effective resource allocation and scheduling scheme based on the subframe structure is proposed to maximize the benefit of the shared relay. System level simulations quantify the system performance in different resource demand situations, and show that the deployment of shared relays can improve significantly the overall system performance and also increase the throughput of cell edge users as compared to the conventional separated cell edge relay station deployment.
Verification of behavioral descriptions by combining symbolic simulation and automatic reasoning (2005)

We present a property verification method for behavioral descriptions with TheoSim, a tool that combines symbolic simulation and automatic reasoning. The effectiveness of the method is illustrated on the verification of SPSMALL, a memory designed by STMicroelectronics. The proof of correctness was established independently of the memory size.
Glypican‐4 is an FGF2‐binding heparan sulfate proteoglycan expressed in neural precursor cells (2000)

FGF2 is a crucial mitogen for neural precursor cells in the developing cerebral cortex. Heparan sulfate proteoglycans (HSPGs) are thought to play a role in cortical neurogenesis by regulating the action of FGF2 on neural precursor cells. In this article, we present data indicating that glypican-4 (K-glypican), a GPI-anchored cell surface HSPG, is involved in these processes. In the developing mouse brain, glypican-4 mRNA is expressed predominantly in the ventricular zone of the telencephalon. Neither the outer layers of the telencephalic wall nor the ventricular zone of other parts of the developing brain express significant levels of glypican-4, with the exception of the ventricular zone of the tectum. In cultures of E13 rat cortical precursor cells, glypican-4 is expressed in cells immunoreactive for nestin and the D1.1 antigen, markers of neural precursor cells. Glypican-4 expression was not detected in early postmitotic or fully differentiated neurons. Recombinant glypican-4 produced in immortalized neural precursor cells binds FGF2 through its heparan sulfate chains and suppressed the mitogenic effect of FGF2 on E13 cortical precursor cells. The spatiotemporal expression pattern of glypican-4 in the developing cerebral wall significantly overlaps with that of FGF2. These results suggest that glypican-4 plays a critical role in the regulation of FGF2 action during cortical neurogenesis.
Identical Binding Energies and Work Functions for Distinct Adsorption Structures: Olympicenes on the Cu(111) Surface (2016)

Reliability is one of the major concerns and challenges in designing organic/inorganic interfaces for (opto)electronic applications. Even small structural differences for molecules on substrates can result in a significant variation in the interface functionality, due to the strong correlation between geometry, stability, and electronic structure. Here, we employed state-of-the-art first-principles calculations with van der Waals interactions, in combination with atomic force microscopy experiments, to explore the interaction mechanism for three structurally related olympicene molecules adsorbed on the Cu(111) surface. The substitution of a single atom in the olympicene molecule switches the nature of adsorption from predominantly physisorptive character [olympicene on Cu(111)], to an intermediate state [olympicene-derived ketone on Cu(111)], then to chemisorptive character [olympicene radical on Cu(111)]. Despite the remarkable difference in adsorption structures (by up to 0.9 Å in adsorption height) and different nature of bonding, the olympicene, its ketone, and its radical derivatives have essentially identical binding energies and work functions upon interaction with the metal substrate. Our findings suggest that the stability and work functions of molecular adsorbates could be rendered insensitive to their adsorption structures, which could be a useful property for (opto)electronic applications.
Mimicking Human Behavior in Shared-Resource Computer Networks (2019)

Among the many challenges in computer network trace data collection is the automation, or mimicking, of human users in situations where humans-in-the-loop are either impracticable or not possible. While client-side human behavior has been automated in various static settings, autonomous clients which dynamically change their behavior as the environment changes may result in a more accurate representation of human behavior in captured network trace data, and thus may be better suited for problems in which humans-in-the-loop are important. In this work, we set out to create dynamic autonomous client-side behavioral models, which we call agents, that can interact with the network environment in much the same way that humans do, and are scalable in shared-resource environments, such as emulated computer networks. We show through multiple experiments and a web crawling case study on an emulated network that our agents can mimic interactive human behavior, and do so at scale.
Au Nanoparticles–3D Graphene Hydrogel Nanocomposite To Boost Synergistically in Situ Detection Sensitivity toward Cell-Released Nitric Oxide (2015)

In situ detection of nitric oxide (NO) released from living cells has become very important in studies of some critical physiological and pathological processes, but it is still very challenging due to the low concentration and fast decay of NO. A nanocomposite of Au nanoparticles deposited on three-dimensional graphene hydrogel (Au NPs-3DGH) was prepared through a facile one-step approach by in situ reduction of Au(3+) on 3DGH to build a unique sensing film for a strong synergistic effect, in which the highly porous 3DGH offers a large surface area while Au NPs uniformly deposited on 3DGH efficiently catalyze the electrochemical oxidation of NO for sensitive detection of NO with excellent selectivity, fast response, and low detection limit. The sensor was further used to in situ detect NO released from living cells under drug stimulation, showing significant difference between normal and tumor cells under drug stimulation.
PROTEIN DENSITIES (1979)

The calculation of protein densities from atomic coordinates is not straight-forward and requires very careful attention to the determination of the protein-solvent boundary. Interior densities are more readily obtained and are in reasonable agreement with those estimated from solvent accessibility studies. The interior of globular proteins has very significant density inhomogenities on a scale of 100--1000 A3. The interior densities range from less than 0.5 g/cm3 to over 3 g/cm3. The low local densities are primarily associated with clusters of nonpolar sidechains while the high local density regions arise from the protein backbone secondary structures: helices and beta sheets. We show a rough correlation between local density and local polarity.
A Multi Antenna Receiver for Galileo SoL Applications (2008)

One of the main features of the Galileo Satellite Navigation System is integrity. To ensure a reliable and robust navigation for Safety of Life applications, like CAT III aircraft landings, new receiver technologies are indispensable. Therefore, the German Aerospace Centre originated the development of a complete safety-of-life Galileo receiver to demonstrate the capabilities of new digital beam-forming and signal-processing algorithms for the detection and mitigation of interference. To take full advantage of those algorithms a carefully designed analogue signal processing is needed. The development addresses several challenging questions in the field of antenna design, frontend development and digital signal processing. The paper will give an insight in the activity and will present latest results.
Long-Term Evolution of Uranium Mobility within Sulfated Mill Tailings in Arid Regions: A Reactive Transport Study (2021)

Management of mill tailings is an important part of mining operations that aims at preventing environmental dispersion of contaminants of concern. To this end, geochemical models and reactive transport modeling provide a quantitative assessment of the mobility of the main contaminants. In arid regions with limited rainfall and intense evaporation, solutes transport may significantly differ from the usual gravity-driven vertical flow. In the uranium tailings of the Cominak mine (Niger), these evaporative processes resulted in the crystallization of gypsum, and to a lesser extent jarosite, and in the formation of surface levels of sulfated gypcrete, locally enriched in uranium. We present a fully coupled reactive transport modeling approach using HYTEC, encompassing evaporation, to quantitatively reproduce the complex sequence of observed coupled hydrogeochemical processes. The sulfated gypcrete formation, porosity evolution and solid uranium content were successfully reproduced at the surface and paleosurfaces of the tailing deposit. Simulations confirm that high solubility uranyl-sulfate phase may form at the atmospheric boundary where evaporation takes place, which would then be transformed into uranyl-phosphate phases after being watered or buried under fresh tailings. As these phases usually exhibit a lower solubility, this transition is beneficial for mine operators and tailings management.
Fault diagnosis method of distributed power distribution network based on advanced Petri net (2017)

A DG-based distributed fault diagnosis method based on BP neural network with dynamic adaptive fuzzy Petri nets is proposed to solve the problem that traditional fault diagnosis methods lead to complex matrix and switching functions. In this paper, the general fault diagnosis model is constructed, and the simplified model of protection information is processed in the form of sets. If the operation mode and protection are changed, the model need not be reestablished, and the logic of the protection circuit breaker error correction is used with high fault tolerance. Secondly, BP algorithm is used to train the fuzzy parameters in the model. Finally, simulation test is carried out for the distribution network with DG, which verifies the reliability and fastness of the method.
Loop structures in hybrids of early RNA and the separated strands of adenovirus DNA. (1977)

Separated strands of adenovirus DNA were annealed with early cytoplasmic RNA and visualized in the electron microscope. DNA-RNA duplex regions within the DNA filaments could be recognized by their heavy contour. This contour was often interrupted at distinct locations by loops of displaced, single-stranded DNA. Loops have been observed and mapped in all four early regions of the genome. The structures appear to signal hitherto unknown mechanisms of eukaryotic gene expression.
Energy and mass‐resolved detection of neutral and ion species using modulated‐pole‐bias quadrupole mass spectroscopy (1990)

An analyzer capable of determining the mass as well as the energy (5–200 eV) of neutral and ion species has been developed from a quadrupole mass spectrometer (QMS). The system, which is similar to a retarding grid energy analyzer (RGEA), functions by biasing the rods of a QMS and monitoring the analyzer signal as a function of bias potential. Modulation of the pole bias greatly increases the minimum detectable signal level. Experiments were performed using species generated in a single‐grid Kaufman ion gun operated with N2 or Ar. Results show that the pole bias techniques can provide energy resolution of 1–2 eV. Ion species from the gun were found to have an energy equal to the sum of the beam and the plasma potentials, with an energy spread between 1 and 3 eV. Fast N2 and Ar neutral species were measured as a function of discharge voltage (30–80 V), beam acceleration voltage (50–100 V), grid voltage (−20 to +5 V), and pressure (0.5 and 1.5 mTorr). The energy of the fast neutral species was always less than that of the ions. This was consistent with the fast neutrals being formed by a charge‐exchange process.
Development and evaluation of a context‐driven, mobile tourist guide (2007)

Purpose The behavior of tourists strongly depends on the availability and quality of information. Too little information as well as too much can be disorienting and forces many tourists to join the majority visiting major sights. This causes a few crowded places in contrast to many which are under‐utilized. A Destination Management Organization has the goal to spread tourists more evenly, whereas the tourists would like to enjoy the destination to its full potential according to their personal interests. The paper aims to focus on the issues surrounding the creation of a mobile tourist guide. Design/methodology/approach A field trial was conducted in the summer of 2005 to study the following questions as a precondition for the development: Is it possible to seed generic interest profiles in the mobile context that allow the accurate prediction of actual rankings? Are the interest profiles sufficiently diverse to base personalized tours on individual interest profiles instead of interest prototypes? How do personalized tours affect the spatial behavior of tourist? Three methods to elicit the generic preferences of tourist in the mobile context are compared with actual rankings using Spearman's rank order coefficient. Findings The diversity of the interest profiles is analyzed in various ways leading to the conclusion that personalized interest profiles are necessary. For the gathered profiles tours are computed and simulated in order to gain a first insight into the effect on the spatial behavior of tourists. Originality/value The dynamic tour guide is supporting both goals by means of pervasive computing based on the actual context which is defined by personal interests, location and schedule of a tourist. It enables a personalized, spontaneous and guided tour.
