Phototherapy with Narrowband UVB
2005-01-01

Phototherapy with ultraviolet (UV) radiation of wavelengths between 280 and 320 nm (UVB) is a safe and effective treatment for a variety of diseases. In addition to standard broadband UVB (bUVB), narrowband phototherapy with fluorescent bulbs emitting near monochromatic UV around 311 nm (nUVB) has become an important treatment for diseases such as psoriasis, atopic dermatitis and vitiligo. In addition to these indications, the number of diseases for which nUVB phototherapy is reported to be effective is continuously growing. The differential effects of nUVB phototherapy in comparison to other UV wavelengths as well as established and new indications for this treatment modality are reviewed.
Scaffolding-based segmentation of coronary vascular structures
2005-01-01

The coronary arteries are essential for the proper function of the human heart. However, they are generally difficult to segment in volume datasets separately from the other blood-filled cavities of the heart. The major reason for these difficulties is the lack of sufficient spatial resolution and partial volume effects. In this paper, we present a method to mark the coronary arteries by a virtual endoscopic traversal. Virtual endoscopy enables a significantly easier visual identification of the blood vessels in comparison to outside views or slice-by-slice examination methods. Furthermore, we use this marking as a scaffold for the actual segmentation of the coronary arteries.
Sermon on Psalm 46
2005-01-01

This 46 th Psalm is an ancient song, dear brothers and sisters, 2 an ancient song of sublime beauty.Its beauty has incited later generations to adopt it freely and they too succeeded, with songs of impressive beauty.Yet it is not the beauty of the Psalm which concerns us now, so much as the truth aflame in its beauty.Who can speak of God in this way?What sort of a people would it have been, which first sang this song?And why?On the basis of what experience could they, moreover must they, have sung such a song?And who can join in?Who can sing this song today, brothers and sisters?And, not least: how should one sing it?C'est le ton, qui fait la musique: the tone makes the music.Which tone, then, is appropriate for this old song?In Lutheran Germany, this Psalm has been readily sung as a song of defiance, with faces directed straight at Rome.Luther's great chorale "Ein feste Burg ist unser Gott" was the Reformation version of this song.In my homeland, this chorale was sung far too militantly, far too stridently -even as a song of defiance, threateningly like a marching song: first and foremost against Rome and then equally, too, against the rest of the world.By contrast, Luther had sung his song to the lute, cautiously, tenderly and heartfelt.Luther's chorale is no marching order -not at all!And neither is its antecedent, the 46 th Psalm.Psalm 46 is much more like a song of trust for fugitives who sought a place in which they could be safe, and who have now, finally, found a truly safe place after every sort of deceptive, false security, which promises repose.Now they are sheltered.And now they praise this place of deliverance in which trust can be placed.

Cortical oscillatory activity during spatial echoic memory
2005-01-01

Abstract In human magnetoencephalogram, we have found gamma‐band activity (GBA), a putative measure of cortical network synchronization, during both bottom‐up and top‐down auditory processing. When sound positions had to be retained in short‐term memory for 800 ms, enhanced GBA was detected over posterior parietal cortex, possibly reflecting the activation of higher sensory storage systems along the hypothesized auditory dorsal space processing stream. Additional prefrontal GBA increases suggested an involvement of central executive networks in stimulus maintenance. The present study assessed spatial echoic memory with the same stimuli but a shorter memorization interval of 200 ms. Statistical probability mapping revealed posterior parietal GBA increases at 80 Hz near the end of the memory phase and both gamma and theta enhancements in response to the test stimulus. In contrast to the previous short‐term memory study, no prefrontal gamma or theta enhancements were detected. This suggests that spatial echoic memory is performed by networks along the putative auditory dorsal stream, without requiring an involvement of prefrontal executive regions.
Architecture for a service-oriented and convergent charging in 3G mobile networks and beyond
2005-01-01

convergent, 3G mobile networks and beyond Services will be the economic driver for 3G mobile networks and beyond. For the provision of new services a charging architecture supporting fast and easy integration of new services on the one hand and enabling versatile tariff models on the other hand is of vital importance. In this paper we present a service-oriented charging architecture. The key idea of the architecture is the separation of service-conscious and service-agnostic areas whereas the different areas are configurable by policy rules. A service example is used to demonstrate the operation and flexibility of our architecture. 1
Real-time cartoon-like stylization of AR video streams on the GPU
2005-01-01

The ultimate goal of many applications of augmented re-ality is to immerse the user into the augmented scene, which is enriched with virtual models. In order to achieve this im-mersion, it is necessary to create the visual impression that the graphical objects are a natural part of the user’s envi-ronment. Producing this effect with conventional computer graphics algorithms is a complex task. Various rendering artifacts in the three-dimensional graphics create a notice-able visual discrepancy between the real background image and virtual objects. We have recently proposed a novel approach to gener-ating an augmented video stream. With this new method, the output images are a non-photorealistic reproduction of the augmented environment. Special stylization methods are applied to both the background camera image and the vir-tual objects. This way the visual realism of both the graph-ical foreground and the real background image is reduced, so that they are less distinguishable from each other. Here, we present a new method for the cartoon-like styl-ization of augmented reality images, which uses a novel post-processing filter for cartoon-like color segmentation and high-contrast silhouettes. In order to make a fast post-processing of rendered images possible, the programmabil-ity of modern graphics hardware is exploited. We describe an implementation of the algorithm using the OpenGL Shading Language. The system is capable of generating a stylized augmented video stream of high visual quality at real-time frame rates. As an example application, we demonstrate the visualization of dinosaur bone datasets in stylized augmented reality. 1.
Localization of mobile robots with omnidirectional vision using particle filter and iterative SIFT
2005-01-01

&lt;p&gt;The Scale Invariant Feature Transform, SIFT, has been successfully applied to robot localization. Still, the number of features extracted with this approach is immense, especially when dealing with omnidirectional vision. In this work, we propose a new approach that reduces the number of features generated by SIFT as well as their extraction and matching time. With the help of a Particle Filter, we demonstrate that we can still localize the mobile robot accurately with a lower number of features.&lt;/p&gt;
Meeting Report: Primary Central Nervous System Lymphoma: Standards Of Care And Future Perspectives
2005-01-01

A standard of care for patients with primary central nervous system lymphoma (PCNSL) has not been defined. Current controversies concern, amongst others, the role, dose and timing of radiotherapy, the role of intrathecal chemotherapy and the delineation of age-specific standards of care. Given the strong clinical trial activities for PCNSL in Germany, the PCNSL conference held in Tubingen aimed at comparing the diverging trial strategies in Germany and at exploring the options for joint activities of the various PCNSL study groups in the near future.
Pressure Dependent Hydraulic Flow, Heat Transport and Geo-thermo-mechanical Deformation in HDR Crystalline Geothermal Systems: Preliminary Application to Identify Energy Recovery Schemes at Urach Spa
2005-01-01

Understanding flow and heat transport pressure and temperature dependent parameters of crystalline rock coupled with geomechanical deformation is particularly important in crystalline geothermal reservoirs. The permeability of these reservoirs is dominated by the fracture systems found within them. In-situ stress conditions have a significant impact on the flow, transport and exchange characteristics of the three dimensional fracture networks. Hydraulic, Thermal and Mechanical coupling (HTM) occurs as a result of the extraction of heat from the reservoirs utilizing high pressure injection and extraction of in situ geofluids. These coupled processes significantly effect the characteristics of heat extraction from the geothermal reservoir. Based on a newly developed and experimentally calibrated geomechanical model, the changes in the flow and transport parameters within crystalline fractures due to changes in local effective stress as a result of the reservoir fluid draw down, water injection and thermal stresses can be estimated. Using a finite element model of the Bad Urach (South West Germany) potential Hot Dry Rock (HDR) geothermal reservoir comprising tetrahedral elements, this mechanical deformation and alteration of fracture parameters is coupled with state of the art fluid parameter functions dependent on pressure, temperature and salinity for heat capacity, conductivity, viscosity and density. The effects of HTM coupled flow and heat extraction on the reservoir characteristics are investigated to assist in the identification of heat recovery schemes for the long term economical operation of the HDR plant.
Illustrative Rendering of Segmented Anatomical Data.
2005-01-01

Medical illustrations use simple drawing styles to demonstrate shapes and features of organs and organ systems, while omitting irrelevant details. In this contribution, we present a non-photorealistic rendering algorithm for illustrating anatomical data. Unlike other existing methods that rely on available triangulations of the organs to be rendered, our approach relies only on a subset of surface points, together with their normals. The advantage is that surface points and normals can be quite easily extracted from medical data, without an intermediate triangulation. 1
High-dose interferon-α2b induction therapy in combination with ribavirin for treatment of chronic hepatitis C in patients with non-response or relapse after interferon-α monotherapy
2005-01-01

Daily high-dose induction therapy with interferon-alpha2b is well tolerated and effective for the treatment of non-responders and relapsers, when interferon monotherapy fails. A fast decline of viral load during the first 12 wk is strongly associated with a sustained viral response.

On the Distribution of Nodes in Distributed Hash Tables.
2005-01-01

Abstract: We develop a model for the distribution of nodes in ring-based DHTs like Chord that position nodes randomly or based on hash-functions. As benefit of our model we get the distribution of interval sizes and an approximation of the distribution of data load among the participating peers. The results match previously published experimental studies on load distribution that motivated the research on load balancing. Most importantly, our model also gives a theoretical explanation for observed load behavior. 1
Using MONA for querying linguistic treebanks
2005-01-01

MONA is an automata toolkit providing a compiler for compiling formulae of monadic second order logic on strings or trees into string automata or tree automata. In this paper, we evaluate the option of using MONA as a treebank query tool. Unfortunately, we find that MONA is not an option. There are several reasons why the main being unsustainable query answer times. If the treebank contains larger trees with more than 100 nodes, then even the processing of simple queries may take hours.
Path coupled accounting mechanisms for "all IP networks"
2005-01-01

Accounting in beyond 3G (B3G) networks is especially challenging, because of the rapidly increasing number of new services and tariff models introduced or to be introduced. Services are not provided statically anymore but must be deployed in short time spans to meet the volatile market demands. As the complexity of the services grows the demand for an equally flexible accounting mechanism increases as well. However nowadays' static accounting approaches with dedicated meters for certain metering tasks might scale badly in this envisioned dynamic environment. Innovative services can not be deployed if expensive accounting tasks in terms of metering resources are required and the dedicated systems cannot guarantee to handle the additional load. On-path configuration of the meters can provide for a dynamic metering configuration. The accounting configuration can be performed agnostic of the roles of the accounting entities in the B3G network architecture allowing a more flexible accounting. The distributed nature of on-path accounting allows for fault tolerance and provides load-balancing. Thus existing metering resources are utilized better and this enables the introduction of demanding accounting mechanisms for new services.
Analytic structure of the Landau gauge gluon propagator
2005-01-01

The results of different non-perturbative studies agree on a power law as the infrared behavior of the Landau gauge gluon propagator. This propagator violates positivity and thus indicates the absence of the transverse gluons from the physical spectrum, i.e. gluon confinement. A simple analytic structure for the gluon propagator is proposed capturing all of its features. We comment also on related investigations for the Landau gauge quark propagator.
Atomic Data for the Atmospheres of Strongly Magnetized Neutron Stars
2005-01-01

We have developed a new method for the fast computation of wavelengths and oscillator strengths for medium‐Z atoms and ions, up to iron, at neutron star magnetic field strengths. The method is a parallelized multi‐configuration Hartree‐Fock approach based on finite‐element and B‐spline techniques. It turns out that typically 15 finite elements are sufficient to calculate energies to within a relative accuracy of 10−5 in 4 or 5 iteration steps using B‐splines of 6th order, with parallelization speed‐ups of 20 on a 26‐processor machine. Results have been obtained for the energies of the ground states and excited levels and for the transition strengths of astrophysically relevant atoms and ions in the range Z = 2 ... 26 in different ionization stages.
Understanding the Limit Order Book: Conditioning on Trade Informativeness
2005-01-01

Electronic limit order books are ubiquitous in markets today. However, theoretical models for limit order markets fail to explain the real world data well. Sandas (2001) tests the classic Glosten (1994) model for order book equilibrium and rejects it. We reconfirm this result for one of the largest European stock markets. We then relax one of the model's assumptions and allow the informational content of trades to change over time. Adapting Hasbrouck's (1991a,b) methodology to estimate time varying trade informativeness we find that it is a slowly mean reverting process. By conditioning on trade informativeness, we find support for the Glosten model's implication that books are more shallow during times of informative market orders. However, a high level of liquidity supply is committed up to an economically significant trade size volume, even when trade informativeness is high. This can be seen as a vindication of the open order book design which dispenses with dedicated market makers. We also find evidence for a market order trader population which is quite heterogenous with respect to price sensitivity.
Efficient Skyline Queries under Weak Pareto Dominance
2005-01-01

Skylines with partial order preference semantics often result in huge answer sets and what is worse, they cannot be computed efficiently. In this paper we will explore the evaluation of so-called restricted skyline queries with partial order preferences under the paradigm of weak Pareto dominance. Weak Pareto dominance removes all objects from skylines, which are dominated by other objects in some query predicates, but in turn do not dominate these objects in any predicate. We will argue that this paradigm yields intuitive results, prove that it leads to lean sizes of the restricted skyline and show how it opens up the use of efficient algorithms for evaluation adopting the iteration of ranked result lists for each query predicate.
Macroeconomic Shocks and Foreign Bank Assets
2005-01-01

Changes in foreign asset holdings are one channel through which agents adjust to macroeconomic shocks. In this paper, we test whether foreign bank assets change as a result of domestic and foreign macroeconomic shocks. We frame our empirical analysis in a standard new open economy macro model in which financial markets are imperfectly integrated. We test the implications of this model using dynamic panel models for changes in foreign bank assets. We find evidence that nominal interest rate differentials and inflation differentials drive changes in foreign bank assets permanently, while growth rate differentials and exchange rates have only a temporary effect.
Signalling effects of a large player in a global game of creditor coordination
2005-01-01

In case of multiple creditors a coordination problem can arise when the borrowingfirm runs into financial distress. Even if the project's value at maturity is enoughto pay all creditors in full, some creditors may be tempted to foreclose on theirloans. We develop a model of creditor coordination where a large creditor movesbefore a continuum of small creditors, and analyze the signalling effects of the largecreditor's investment decision on the subsequent behavior of the small creditors. Thesignalling effects crucially depend on the relative size of the large creditor and therelative precision of information. We derive conditions under which pure herdingbehavior is to be expected.

Live graphics gems as a way to raise repositories for computer graphics education
2005-01-01

This contribution presents two technologies, code-based interactivity and server-side compiling, that add value to an educational repository and address its difficulties in achieving a critical mass of submissions. It is part of current efforts in the computer graphics community to collect, preserve, and share educational material. We propose a novel repository service introducing "live" graphics gems to the material, i.e. modifiable program listings with corresponding interactivities that are compiled and versioned server-side. That way, repository material evolves on the fly. Authors not willing to submit their material as open source are given a granular source control. We describe implications, e.g. a common, repository-driven content markup, didactics of code-based interactivity, and crucial technical services and tools. Prototype implementations and showcases are included.
Construction of a diagnostic support system for circulatory disease in a volume communications environment
2005-01-01

We have constructed a diagnostic support system for circulatory disease based on a volume communications environment. This system is based on a VizGrid environment, i.e. an integrated environment consisting of a data archiving system, a collaboration system, and a computational grid system. In this system, we simulate blood flow in a patient's individual blood vessel geometry and blood vessel wall using a weak coupling method. This system can be used with three-dimensional images from CT/MRI, for medical treatment and for simulating blood flow in a blood vessel with circulatory disease in a volume communications environment. With this system, it becomes easy for researchers in remote locations to collaboratively discuss the relevant object, even for complex explanations like the simulation results.
