Lasergenerierte funktionale Nanopartikel-Polymer-Komposite als Ionenfreisetzungssysteme für medizinische Anwendungen

Die Wundheilung beim Menschen ist ein auserst komplexer Prozess, der insbesondere bei schweren Brandverletzungen aufgrund moglicher Infektionen einen langen Zeitraum in Anspruch nehmen kann. Durch die Verletzung ist der Haushalt der Metallionen, welche essentiell an der Wundheilung beteiligt sind, gestort. Ein vielversprechender Ansatz zur Unterstutzung der Heilung liegt daher in der Ionenzugabe aus Verbandsmaterialien, wofur sich besonders lasergenerierte Nanopartikel-Polymer-Komposite anbieten. In dieser Arbeit wurde die Herstellung eines Kompositmaterials mit lasergenerierten Nanopartikeln als Ionendepot, in situ eingebettet in eine Copolymermatrix, auf rein wassriger Basis durchgefuhrt. Dadurch konnten die hohen Reinheitsanspruche fur medizinische Anwendungen erfullt werden. Bei der Herstellung von Nanopartikeln wurde fur eine moglichst hohe Produktivitat eine Optimierung der Laser-, Prozess-, Material- und Fluidparameter durchgefuhrt. Daruber hinaus wurde eine Untersuchung der Laser-Material-Wechselwirkung anhand der Erzeugung von laser-induzierten periodischen Oberflachenstrukturen durchgefuhrt, wobei der Einfluss der Losungsmitteleigenschaften auf die Strukurbildung gezeigt wurde. Dies ermoglichte ein besseres Verstandnis des Laserabtragsprozesses. Damit wurden Komposite mit unterschiedlichen Zusammensetzungen hergestellt, welche anschliesend durch Elektrospinnen zu einem Fasernetzwerk als Wundauflage oder durch Bioextrusion zu einem Scaffold weiterverarbeitet werden konnten. Die Systeme zeigten eine stabile Einbettung der Nanopartikel im Polymer sowie eine gute Biokompatibilitat. Ionenfreisetzungsstudien belegten eine kontinuierliche Ionenabgabe eines oder mehrerer Elemente uber einen Zeitraum von 105 h. Nach der Bestimmung des Ionengehalts in einer Wunde zu verschiedenen Heilungszeiten anhand von Rattenhaut zeigte dies, dass die Komposite fur eine Unterstutzung aller Heilungsstadien genutzt werden konnen. Zudem konnte durch die Eisenionenfreisetzung auch eine Verbesserung der Zelladhasion und Viabilitat von humanen Endothelzellen, sowie in ersten Experimenten ein Einfluss auf die fruhe Stammzelldifferenzierung erzielt werden. Die Studien dieser Arbeit zeigten, dass die hergestellten Nanopartikel-Polymer-Komposite durch ihre einfache und flexible Herstellung fur verschiedene Anwendungen schnell angepasst und in verschiedenen Bereichen der Medizin angewendet werden konnen.
Of hype and hyperbolas: introducing the new economic geography

Reviewing The Spatial Economy by Fujita, Krugman, and Venables, this paper argues that the key contribution of the new economic geography is a framework in which standard building blocks of mainstream economics (especially rational decision making and simple general equilibrium models) are used to model the trade-off between dispersal and agglomeration. The approach thus gives a choice-theoretic basis for a "propensity to agglomerate. "
Universal space-time codes from standard trellis codes

In the absence of accurate channel probability distribution information or in broadcast scenarios, code design for consistent channel-by-channel performance, rather than average performance, may be desirable. Root and Varaiya’s compound channel theorem promises the existence of universal codes that operate with a consistent proximity to channel mutual information on any instance of the compound linear vector Gaussian channel that is similar to the capacity gap of an AWGN-specific code with similar complexity on the AWGN channel. This study presents single-dimensional trellis codes such that when multiplexed over two, three and four transmit antennas, provide universal performance over the compound linear vector Gaussian channel. As a result of their channel-by-channel consistency, the universal trellis codes presented here deliver comparable or in some cases superior frame-error-rate and bit-errorrate performance under quasistatic Rayleigh fading to trellis codes of similar complexity that are designed specifically for the quasistatic Rayleigh fading scenario.
Seamless Code Reuse with Source Code Corpus

Code reuse is attracting much attention as a promising technique for efficient software development. However, code reuse itself requires human resources: for example, searching and opening source files including code fragments that users would like to reuse, or considering keywords in using code search systems. The present paper proposes a novel technique that hardly requires such reuse cost. In the proposed technique, what programmers have to do for obtaining reusable code is just inputting a trigger key for code reuse on their development environments. Also, this paper describes some applications on OSS with a prototype tool working on Eclipse.
Visual tracking of robots in uncalibrated environments

This paper presents a new adaptive controller for visual tracking control of a robot manipulator in 3D general motion with a fixed camera whose intrinsic and extrinsic parameters are uncalibrated. In addition to camera parameters, the feature positions in 3D space are also assumed unknown. Based on the fact that the unknown parameters appears linearly in the closed-loop dynamics of the system if the depth-independent interaction matrix is adopted to map the image errors onto the joint space of the manipulator, we developed a new adaptive algorithm to estimated the unknown parameters on-line. With a full consideration of dynamic responses of the robot manipulator, we employ the Lyapunov method to prove asymptotic convergence of the image errors. Experimental results are used to demonstrate the performance of the proposed approach.
Computational complexity of probabilistic Turing machines

Probabilistic Turing machines are Turing machines with the ability to flip coins in order to make random decisions. We allow probabilistic Turing machines small but nonzero error probability in computing number-theoretic functions. An example is given of a function computable more quickly by probabilistic Turing machines than by deterministic Turing machines. It is shown how probabilistic linear-bounded automata can simulate nondeterministic linear-bounded automata.
Self-Organisation Can Explain the Mapping of Angular Whisker Deections in the Barrel Cortex

A topographic mapping of angular whisker deflections has recently been discovered in the barrel cortex of rats (Andermann & Moore, 2006). Characteristics of this map suggest that it could emerge in post-natal development, through self-organisation under a Hebbian learning regime. This hypothesis was implemented in a self-organising computational model, from which a remarkably similar mapping emerges when whisker deflections are correlated during training. The model is used to predict mappings that might emerge if whisker deflections are un-correlated, random, or anti-correlated during development, and work towards a more sophisticated input system is documented.
A robotics-inspired method to sample conformational paths connecting known functionally-relevant structures in protein systems

Characterization of transition trajectories that take a protein between different functional states is an important yet challenging problem in computational biology. Approaches based on Molecular Dynamics can obtain the most detailed and accurate information but at considerable computational cost. To address the cost, sampling-based path planning methods adapted from robotics forego protein dynamics and seek instead conformational paths, operating under the assumption that dynamics can be incorporated later to transform paths to transition trajectories. Existing methods focus either on short peptides or large proteins; on the latter, coarse representations simplify the search space. Here we present a robotics-inspired tree-based method to sample conformational paths that connect known structural states of small- to medium- size proteins. We address the dimensionality of the search space using molecular fragment replacement to efficiently obtain physically-realistic conformations. The method grows a tree in conformational space rooted at a given conformation and biases the growth of the tree to steer it to a given goal conformation. Different bias schemes are investigated for their efficacy. Experiments on proteins up to 214 amino acids long with known functionally-relevant states more than 13ÅA apart show that the method effectively obtains conformational paths connecting significantly different structural states.
Narratives in the Situation Calculus

A narrative is a course of real events about which we might have incomplete information. Formalisms for reasoning about action may be broadly divided into those which are narrative-based, such as the Event Calculus of Kowalski and Sergot, and those which reason on the level of hypothetical sequences of actions, in particular the Situation Calculus. This paper bridges the gap between these types of formalism by supplying a technique for linking incomplete narrative descriptions to Situation Calculus domain formulae written in the usual style using a Result function. Particular attention is given to actions with duration and overlapping actions. By illuminating the relationship between these two diierent styles of representation, the paper moves us one step closer to a full understanding of the space of all possible formalisms for reasoning about action.
Ground-based experiments towards the interception of non-cooperative space debris with a robotic manipulator

This paper presents an account of the experimentations with a ground-based facility emulating interception scenarios with non-cooperative space debris using a robotic manipulator. A sampling-based motion-planning algorithm is used to autonomously solve the dynamic interception problem without collisions and under velocity, acceleration and jerk constraints. Invariant Kalman filter methodologies are employed to estimate and predict the motion of a neutrally-buoyant airship emulating a free-floating target. Discussions are presented on the mitigation of practical issues of system integration and the operation of a sensitive, but cost-effective, test-bed for aerial neutral-buoyancy experiments. An account of ground-based experiments is presented as well as results showing good success rates on the tested scenarios and methods that constitute the first reported set of experiments on the interception phase of active space debris removal.
A comparative evaluation of fracture load of monolithic and bilayered zirconia crowns with and without a cervical collar: an in vitro study

Introduction The use of zirconia based all-ceramic restorations are preferred nowadays owing to superior biologic and esthetic properties. However, these restorations have also reported higher incidences of fracture and chipping. The clinical success may be enhanced by optimizing the core design, through the introduction of monolithic zirconia, or the layered crowns can be strengthened by adding the cervical collar to them. Objective This study was performed with the objective to compare and evaluate the fracture load of monolithic and bilayered zirconia crowns with and without a cervical collar. Methods A prospective observational study was carried out to compare 45 fabricated zirconia crowns of three different designs on a customized metal mould. The samples were oriented on the metal mould and subjected to confocal microscope for the evaluation of marginal integrity followed by cementing the crown on the metal mould and subjecting it to the universal testing machine for the analysis for the flexural strength. Data were analyzed using one way Anova and t- test for inter and intra groups. The significance level was set at P ≤ 0.05. Results The monolith zirconia crowns and layered zirconia crowns with cervical collar reported more flexural strength. Conclusion The amount of force required to fracture the zirconia crowns was higher in the case of monolith zirconia crown and layered zirconia crown with cervical collar as compared to the layered zirconia crown without cervical collar.
Controlled and Balanced Dataset for Japanese Lexical Simplification

We propose a new dataset for evaluating a Japanese lexical simplification method. Previous datasets have several deficiencies. All of them substitute only a single target word, and some of them extract sentences only from newswire corpus. In addition, most of these datasets do not allow ties and integrate simplification ranking from all the annotators without considering the quality. In contrast, our dataset has the following advantages: (1) it is the first controlled and balanced dataset for Japanese lexical simplification with high correlation with human judgment and (2) the consistency of the simplification ranking is improved by allowing candidates to have ties and by considering the reliability of annotators.
Predictors of Survival in HIV-Infected Patient after Initiation of HAART in Zewditu Memorial Hospital, Addis Ababa, Ethiopia

Introduction. ART has improved the survival of HIV-infected patients. However, patients in resource-poor countries have higher mortality rates, particularly the first months after initiating ART. In this study we tried to determine the survival factors in HIV-infected patients treated with HAART in Zewditu Memorial Hospital. Methods. A retrospective cohort study was conducted from 2008 to 2012. All HIV-infected patients above the age of 14 took first line ART. Data were collected, entered, and analyzed using Epi Info 7 and SPSS Version 20. Life table was used to estimate mortality after initiation of ART, and Kaplan-Meier was used to compare survival curves. Cox proportional hazards model was used to assess the predictors of mortality. Results. The incidence of mortality was 3.8/100 person-years. Independent predictors of mortality were WHO clinical stages 3-4 (HR = 2.39 at 95% CI (1.26, 5.31)), anemia (hemoglobin level < 10 gm/dL (HR = 5.54 at 95% CI (2.58, 11.86)). Conclusion. Incidence of mortality was found relatively low, majority of deaths occurring within 3 months of starting ART. WHO stages 3-4, anemia (hemoglobin count < 10 gm/dL), and past TB coinfection were the main predictors of mortality. The underlying causes for early death in patients presenting at late stages should be investigated.
Planning and Real Time Control of a Minimally Invasive Robotic Surgery System

This paper introduces the planning and control software of a teleoperating robotic system for minimally invasive surgery. It addresses the problem of how to organize a complex system with 41 degrees of freedom including robot setup planning, force feedback control and nullspace handling with three robotic arms. The planning software is separated into sequentially executed planning and registration procedures. An optimal setup is first planned in virtual reality and then adapted to variations in the operating room. The real time control system is composed of hierarchical layers. The design is flexible and expandable without losing performance. Structure, functionality and implementation of planning and control are described. The robotic system provides the surgeon with an intuitive hand-eye-coordination and force feedback in teleoperation for both hands.
An audio feature extraction scheme based on spectral decomposition

This paper presents an audio feature extraction scheme based on spectral decomposition where the decomposition is performed iteratively by matching-pursuit in frequency domain. Motivated by psychoacoustic studies, a set of spectral basis vectors are constructed to extract pitch, timbre and residual inharmonic components from spectrum. The audio feature is represented by the scales of basis vectors after dimension reduction. The proposed feature is evaluated on a 13-category audio effect classification task. The experimental results show the proposed feature outperforms other spectral and cepstral features.
Introduction to a Non-Commutative Version of the Standard Model

This article provides a basic introduction to some concepts of non-commutative geometry. The importance of quantum groups and quantum spaces is stressed. Canonical non-commutativity is understood as an approximation to the quantum group case. Non-commutative gauge theory and the non-commutative Standard Model are formulated on a space-time satisfying canonical non-commutativity relations. We use *-formalism and Seiberg-Witten maps.
A study on crop yield forecasting using classification techniques

India is generally an agricultural country. Agriculture is the single most important contributor to the Indian economy. Agriculture crop production depends on the season, biological, and economic cause. The prognosticating of agricultural yield is a challenging and desirable task for every nation. Nowadays, Farmers are struggling to produce the yield because of unpredictable climatic changes and drastically reduce in water resource so; we are creating an agriculture data. This data could be gathered, stored and analyzed for useful information. It is used to promote new advanced methods and approaches such as data mining that can give the information of the previous results to the crop yield estimation. In this paper, we have demonstrated to estimate the crop yield, choose the most excellent crop, thereby improves the value and gain of the farming area using data mining techniques.
Twist-related Locomotion of a 3D Snake-like Robot

As a hyper-redundant robot, a 3D snake-like robot can perform many other configurations and types of locomotion adapted to environment except for mimicking the natural snake locomotion. The natural snake locomotion usually limits locomotion capability of the robot because of inadequacy in the mechanism and actuation to imitate characters of natural snake such as the too many DOFs and the characteristics of the muscle. In order to apply snake-like robots to the unstructured environment, the researchers have designed many gaits for increasing the adaptability to a variety of surroundings. The twist-related locomotion is an effective gait achieved by jointly driving the pitching-DOF and yawing-DOF, with which the snake-like robot can move on rough ground and even climb up some obstacles. In this paper, the twist-related locomotion function is firstly solved, and simplified to be expressed by sine or cosine function. The 2D locomotion such as V-shape and U-shape is achieved. Also by applying it to the serpentine locomotion or other types of locomotion, the snake-like robot can complete composite locomotion that combines the serpentine locomotion or others with twist-related locomotion. Then we extend the twist related locomotion to 3D space. Finally, the experimental results are presented to validate all above analyses
LATTICE RESCORING EXPERIMENTS WITH DURATION MODELS

This paper reports on experiments using phone and word duration models to improve speech recognition accuracy. The duration information is integrated into state-of-the-art large vocabulary speech recognition systems by rescoring word lattices that include phone-level segmentations. Experimental results are given for a conversational telephone speech (CTS) task in French and for the TC-Star EPPS transcription task in Spanish and English. An absolute word error rate reduction of about 0.5% is observed for the CTS task, and smaller but consistent gains are observed for the EPPS task.
On the asymptotic effectiveness of Weil descent attacks

Abstract In this paper we investigate the asymptotic effectiveness of the Gaudry–Hess–Smart Weil descent attack and its generalization to the discrete logarithm problem for elliptic curves over characteristic-two finite fields. In particular we obtain nontrivial lower and upper bounds on the smallest possible genus to which it can lead.
Alcove path and Nichols-Woronowicz model of the equivariant K-theory of generalized flag varieties

Fomin and Kirillov initiated a line of research into the realization of the cohomology and K-theory of generalized flag varieties G/B as commutative subalgebras of certain noncommutative algebras. This approach has several advantages, which we discuss. This paper contains the most comprehensive result in a series of papers related to the mentioned line of research. More precisely, we give a model for the T -equivariant K-theory of a generalized flag variety KT (G/B) in terms of a certain braided Hopf algebra called the Nichols-Woronowicz algebra. Our model is based on the Chevalley-type multiplication formula for KT (G/B) due to the first author and Postnikov; this formula is stated using certain operators defined in terms of so-called alcove paths (and the corresponding affine Weyl group). Our model is derived using a type-independent and concise approach. Dedicated to Professor Kenji Ueno on the occasion of his sixtieth birthday
Peer Victimization and School Adjustment Among Ethnically Diverse Middle School Students: Does Ethnic Ingroup Representation Matter?

Although research has shown that peer victimization is related to negative school outcomes, whether ethnic ingroup size alters victimization-adjustment links is unclear. This study examines whether smaller ethnic ingroup representation amplifies the negative associations between peer victimization and school adjustment. We also examine whether ingroup representation may be more salient for some ethnic groups than others. The ethnically diverse sample includes 4,577 students from 26 schools spanning from the fall of sixth grade to spring of seventh grade (41% Latino, 26% White, 17% Asian American, 16% African American). An interaction between victimization and ethnic ingroup representation emerged only among Latino students. Latino youth victimized in the sixth grade, who attended a school with fewer same-ethnic peers, showed increases in negative seventh-grade climate perceptions and decreases in engagement. Our findings highlight that for Latino youth, ethnic ingroup representation is an important factor to consider when examining the school-related adjustment of victimized youth.
ETX Based Routing Metrics

Wireless Multi-hop Networks (WMhNs) are supposed to be the forerunner among the currently existing communication technologies. They provide users with flexible structures, feasible cost, convenience, ever growing bandwidths and innovative solutions. The increasing demands of the users provide a challenge to improve the quality of WMhNs. The performance of WMhNs depends upon the efficiency of the routing protocol operating it. The most important component of a routing protocol is routing link metric. Depending on the demands, the routing protocol must choose a realis tic routing link metric to select the quality links. This paper surveys routing metrics based on Expected Transmission Count (ETX) . Keywords— ETX, IBETX, mETX, Adv-ILA, Adv-iAWARE, Routing metrics, Wireless Mesh Networks, Wireless Multi -hop Networks.
The Global South at the UN: Using International Politics to Re-Vision the Global

ABSTRACT:This article argues that the countries of the Global South have defined themselves in a globally-positioned way since the 1960s—long before the current wave of neoliberal globalization or academic thinking about the "Global South. " This is shown by tracing the history of the formation of the Global South as a political bloc as the Group of 77 (G77) and in their aspirations and negotiations at the United Nations. The article explores how the G77 acts in the global political system, as well as how it tries to act on the global political system in order to produce a particular vision of the global. This is done through an analysis of some of the G77's proposals of how to restructure the global order, including the Declaration on the Establishment of a New International Economic Order, and more recently in the UN's Financing for Development conferences. The South's vision of the global, with stark disparities between North and South and their proposals to ameliorate the situation, is contrasted with a newly emerging Northern vision, which seeks to dissolve North and South into a homogeneous "global" in which power and inequality are not salient.
