acute limb ischemia
revascularization
risk factors

description: Introduction: acute limb ischemia is characterized by a sudden and severe reduction in blood supply to the limb, posing a critical threat to its viability. The incidence of complications associated with ALI remains significantly high. Currently, there is no consensus regarding which preoperative factors influence the incidence of complications in different revascularization methods, nor to what extent they contribute to postoperative outcomes. An analysis of the key predictors of complications will facilitate the development of preventive strategies and establish criteria for selecting the most appropriate treatment approach for ALI. Materials and methods: this study analyzes the outcomes of two treatment methods for ALI classified as Rutherford class II: open surgical intervention (Group I, n = 50) and endovascular procedures (Group II, n = 50). Results and discussion: the composition and impact of preoperative risk factors differed between the two revascularization methods. In the open surgery group, patients with an inflammatory, hypovolemic, or thrombophilic etiology of ALI (11) demonstrated a higher likelihood of an unfavorable postoperative course. Additionally, advanced patient age (7.1), Rutherford ischemia class IIB (0.2), a history of CAD (6.1), DM (9.2), CKD (12.1), and RF (8.5) were identified as significant risk factors for postoperative complications. In the endovascular revascularization group, among perioperative risk factors, the following variables demonstrated significant associations with postoperative complications: CAD (4.9), CKD (12.4), DM (5.28), RF (11), and Rutherford ischemia class IIB (0.2). Conclusion: selecting an appropriate revascularization method based on an individualized risk factor profile for each patient can effectively reduce the incidence of complications in the early postoperative period.

description: Studies examining the value of switching to a variable rate technology (VRT) fertilizer program assume producers possess perfect soil nitrate information. In reality, producers estimate soil nitrate levels with soil sampling. The value of switching to a VRT program depends on the quality of the estimates and on how the estimates are used. Larger samples sizes, increased spatial correlation, and decreased variability improve the estimates and increase returns. Fertilizing strictly to the estimated field map fails to account for estimation risk. Returns increase if the soil sample information is used in a Bayesian fashion to update the soil nitrate beliefs in nonsampled sites.

description: We construct Godel-type black hole and particle solutions to Einstein-Maxwell theory in 2+1 dimensions with a negative cosmological constant and a Chern-Simons term. On-shell, the electromagnetic stress-energy tensor effectively replaces the cosmological constant by minus the square of the topological mass and produces the stress-energy of a pressure-free perfect fluid. We show how a particular solution is related to the original Godel universe and analyze the solutions from the point of view of identifications. Finally, we compute the conserved charges and work out the thermodynamics.

description: There is concern in the beef industry that present marketing practices may be impending the transmission of economic signals from consumers to producers. Presently, fed cattle may be sold on a show list, pen-by-pen, or on an individual head basis, and may be priced using live weight, dressed weight, or grid or formula pricing. Market signals are more likely to reach producers if cattle are priced individually. Current value-based pricing are discussed. Three grid pricing systems are evaluated over six marketing dates using data from 5,520 head of fed cattle. Each of the grids do send the anticipated pricing signals in that marbling and leanness are rewarded. However, the magnitudes of the price signals vary over time and across grids.

description: We show that a 7-dimensional non-compact Ricci-flat Riemannian manifold with Riemannian holonomy G_2 can admit non-integrable G_2 structures of type R + S^2_0(R^7) + R^7 in the sense of Fernández and Gray. This relies on the construction of some G_2 solvmanifolds, whose Levi-Civita connection is known to give a parallel spinor, admitting a 2-parameter family of metric connections with non-zero skew-symmetric torsion that has parallel spinors as well. The family turns out to be a deformation of the Levi-Civita connection. This is in contrast with the case of compact scalar-flat Riemannian spin manifolds, where any metric connection with closed torsion admitting parallel spinors has to be torsion-free.

description: Crop protection is a part of the agricultural production system. In Europe during the past century, this system has been subject to innovation, stemming from the second agricultural revolution of the Modern Time. Today we are on the crossroad of three alternative agricultural systems. Conventional agriculture is the product of the second agricultural revolution. So far, biotechnological agriculture seems to continue these trends. Organic agriculture on the other hand is a reaction on the paradigm of the second agricultural revolution, especially regarding the negative environmental externalities engendered by this revolution. Today, conventional agriculture is under pressure. Two alternatives have emerged: organic and biotechnological agriculture. Which one is the most economical solution? To answer this question, we analyze these agricultural innovations in a historical perspective, emphasizing the socio-economic evolution process of the production systems during the last century and some of the recent institutional changes. Then we compare short-term micro-economic profitability of conventional versus biotechnological agriculture and conventional versus organic agriculture. To analyze biotechnological agriculture, we refer to two important innovations which have recently been introduced in the Unites States, i.e. glyphosate-resistant soybeans and Bt corn. For the latter, we develop a theoretical micro-economic production model, enabling to represent the effects of Bt corn on total crop protection costs. Finally, we enlarge the scope and compare the macro-economic effects among the three alternatives. The long-term aspects as well as the non-market effects or externalities are taken into account. We conclude the analysis and give some future perspectives. Door middel van een vergelijkende analyse worden de micro- en macro-economische kosten en baten en externaliteiten voor de Europese Unie van drie alternatieve landbouwproductie-systemen afgewogen: gangbare, biotechnologische en biologische. De biotechnologische innovaties blijken valabele alternatieven te bieden voor de gangbare landbouw zowel op micro- als op maco-economische schall, ondanks het feit dat een deel van de voordelen geabsorbeerd wordt door de biotechnologische industrie. De biologische landbouw kenmerkt zich, ondanks haar lagere fysische productiviteit, door een rentabiliteit die vergelijkbaar is met de conventionele landbouw. Ook op macro-economisch vlak heeft dit landbouwsysteem heel wat voordelen te bieden. De toekomst van deze drie landbouwsystemen zal afhangen van hun onderlinge rentabiliteitsverhoudingen, alsook van politieke en sociale factoren, zoals bijvoorbeeld de consumentenhouding ten opzichte van nieuwe technologieen.

description: The class of Double-Double Radio Galaxies (DDRGs) relates to episodic jet outbursts. How various regions and components add to the total intensity in radio images is less well known. In this paper we synthesize synchrotron images for DDRGs based on special relativistic hydrodynamic simulations, making advanced approximations for the magnetic fields. We study the synchrotron images for: Three different radial jet profiles; Ordered, entangled or mixed magnetic fields; Spectral ageing from synchrotron cooling; The contribution from different jet components; The viewing angle and Doppler (de-)boosting; The various epochs of the evolution of the DDRG. To link our results to observational data, we adopt to J1835+6204 as a reference source. In all cases the synthesized synchrotron images show two clear pairs of hotspots, in the inner and outer lobes. The best resemblance is obtained for the piecewise isochoric jet model, for a viewing angle of approximately $\vartheta \sim -71^{\circ}$, i.e. inclined with the lower jet towards the observer, with predominantly entangled ($\gtrsim 70$ per cent of the magnetic pressure) in turbulent, rather than ordered fields. The effects of spectral ageing become significant when the ratio of observation frequencies and cut-off frequency $ν_{\rm obs}/ν_{\infty,0} \gtrsim 10^{-3}$, corresponding to $\sim 3 \cdot 10^2$ MHz. For viewing angles $\vartheta \lesssim -30^{\circ}$, a DDRG morphology can no longer be recognized. The second jets must be injected within $\lesssim$ 4 per cent of the lifetime of the first jets for a DDRG structure to emerge, which is relevant for Active Galactic Nuclei feedback constraints.

Noise reduction for video signals
Creators: name: Li, Xiaoli
Publisher: name: University of British Columbia
Year: 2009

description: Noise reduction is an important aspect of video processing. This thesis proposes a motion adaptive temporal-spatial noise reduction system. The three-step motion detection algorithm is the key for the system. First the pixel-to-pixel difference between two frames are compared to a threshold. This step gives a preliminary motion detection result for each pixel in the target frame. The preliminary motion detection results then go through the impulse pattern recognition module, where some false detections are corrected. The last step of the motion detection method is the spatial motion detection. It corrects those motion pixels that were mis-detected as still pixels in previous steps. Therefore, the pixel accurate motion detection results between the target frame and a reference frame is obtained. These results are used to control the operations of the temporal filter and the spatial filter. The temporal average filter only operates on the pixels that is not in motion to avoid motion artifacts. The edge adaptive spatial filter does little spatial filtering in the still areas of the picture to maintain the spatial resolution, while does more aggressive filtering in motion areas of the picture because the human eye is less sensitive to the blurring of moving objects. Therefore, the maximum noise reduction effect is achieved. The proposed algorithm is implemented both in a hardware prototype using FPGAs and as a real-time software module on a VLIW DSP chip. Both prototypes made the intensive subjective evaluations of the algorithm possible. It is proved that the algorithm improves the picture quality about 6 dB, in terms of signal-tonoise ratio and subjective estimation, for most of the noisy pictures. It introduces minimum artifacts.

description: We compute the general expression of the one-loop vertex correction in an arbitrary plane-wave background field for the case of two on-shell external electrons and an off-shell external photon. The properties of the vertex corrections under gauge transformations of the plane-wave background field and of the radiation field are studied. Concerning the divergences of the vertex correction, the infrared one is cured by assigning a finite mass to the photon, whereas the ultraviolet one is shown to be renormalized exactly as in vacuum. Finally, the corresponding expression of the vertex correction within the locally-constant crossed field is also derived and the high-field asymptotic is shown to scale according to the Ritus-Narozhny conjecture.

description: Das Miterleben von Paargewalt kann für Kinder unterschiedliche Auswirkungen haben. Kinder, welche in einer Atmosphäre der Gewalt aufwachsen, werden von der Öffentlichkeit wenig wahrgenommen. Die vorliegende Bachelor-Arbeit nimmt sich dem Thema an. Anhand konkreter Beispiele werden Interventionsmöglichkeiten für die unterschiedlichen Praxisfelder der Sozialen Arbeit in der Begleitung betroffener Kinder aufgezeigt. Die Begriffe Gewalt, häusliche Gewalt und Paargewalt werden in der Arbeit eingehend beschrieben und für diese Bachelor-Arbeit definiert. Verschiedene Studien zu Auswirkungen von Paargewalt auf das Kind wurden in dieser Arbeit zusammengetragen. Mit unterschiedlichen Entwicklungstheorien konnte aufgezeigt werden, welche Aspekte für eine gesunde kindliche Entwicklung wichtig sind. Verschiedene Bedingungen, die sich in Form von Risiko- und Schutzfaktoren auf die kindliche Entwicklung auswirken, wurden durchleuchtet. Dabei erwies sich Resilienz als zentraler Schutzfaktor. Deshalb wurden konkrete Methoden, zur Resilienzförderung ausgearbeitet. Es hat sich gezeigt, dass für die Bildung von Resilienz stabile, fürsorgliche Bindungserfahrungen essentiell sind. Bei den aufgezeigten Interventionsmöglichkeiten wurde speziell darauf geachtet. Das Miterleben von Paargewalt kann für Kinder eine traumatische Erfahrung darstellen und es können sich psychische Störungen entwickeln, die sich bis in das Erwachsenenalter manifestieren. Deshalb fordert diese Arbeit Fachpersonen der Sozialen Arbeit zu traumasensiblem Handeln im Umgang mit Betroffenen auf. Weitere Forderungen an die Sozialen Arbeit, die Veränderungen auf individueller- und gesellschaftlicher Ebene bedingen, werden aufgezeigt.

We discuss possible extensions of this approach like the inclusion of vertex corrections.

description: The large oscillator strength of excitons in transition metal dichalcogenide layers facilitates the formation of exciton-polariton resonances for monolayers and van-der-Waals heterostructures embedded in optical microcavities. Here, we show, that locally changing the number of layers in a WSe2/hBN/WSe2 van-der-Waals heterostructure embedded in a monolithic, high-quality-factor cavity gives rise to a local variation of the coupling strength. This effect yields a polaritonic stair case potential, which we demonstrate at room temperature. Our result paves the way towards engineering local polaritonic potentials at length scales down to atomically sharp interfaces, based on purely modifying its real part contribution via the coherent light-matter coupling strength g.

description: In the present paper we estimate the impact of a biotechnology innovation in Spanish agriculture. Transgenic Bt maize offers the potential to control corn borers, that cause economically important losses in Spanish maize cultivation, more efficiently. Since 1998, Syngenta commercializes the varieties 'Compa CB' and 'Jordi CB', equivalent to an annual area of 20.000 ha, or an average adoption rate of 5,2% of Spain's total land allocation to maize. The profit increase engendered by this technological change during the four-year period 1998-2001 is estimated to be 8,7 million E for Spanish agriculture and 2,8 million E for Syngenta and the seed suppliers. The industry appears to be able to extract only one fourth of the total benefits. The lion share, i.e. three fourths, accrues to farmers.

description: Microarrays are one of the modern technologies for analyzing biological polymers (DNA, RNA, antibodies, etc.). The main advantage of microarrays is the ability to simultaneously analyze a large number of different molecules in one sample. Microarrays are actively used to develop diagnostic tools, including in the analysis of community-acquired pneumonia pathogens. The relevance of studying community-acquired pneumonia is determined by the consistently high incidence, diversity of pathogens and their high genetic variability, as well as the recent spread of a new coronavirus infection. This review describes microarray technologies used to solve fundamental and clinical problems in the study of pathogens of community-acquired pneumonia and some other respiratory infections.

description: The stability of the fluorescence telescopes of the Pierre Auger Observatory is monitored with the optical relative calibration setup. Optical fibers distribute light pulses to three different diffuser groups within the optical system. The total charge per pulse is measured for each pixel and compared with reference calibration measurements. This allows monitoring the short and long term stability with respect of the relative timing between pixels and the relative gain for each pixel. The designs of the LED calibration unit (LCU) and of the Xenon flash lamp used for relative calibration, are described and their capabilities to monitor the stability of the telescope performances are studied. We report the analysis of relative calibration data recorded during 2004. Fluctuations in the relative calibration constants provide a measure of the stability of the FD.

description: The vertical profiles of disc galaxies are built by the material trapped around stable periodic orbits, which form their "skeletons". According to this, the knowledge of the stability of the main families of periodic orbits in appropriate 3D models, can predict possible morphologies for edge-on disc galaxies. In a pilot survey we compare the orbital structures which lead to the appearance of "peanuts" and "X"-like features with the edge-on profiles of three disc galaxies (IC 2531, NGC 4013 and UGC 2048). The subtraction from the images of a model representing the axisymmetric component of the galaxies reveals the contribution of the non-axisymmetric terms. We find a direct correspondence between the orbital profiles of 3D bars in models and the observed main morphological features of the residuals. We also apply a simple unsharp masking technique in order to study the sharpest features of the images. Our basic conclusion is that the morphology of the boxy "bulges" of these galaxies can be explained by considering disc material trapped around stable 3D periodic orbits. In most models these building-blocks periodic orbits are bifurcated from the planar central family of a non-axisymmetric component, usually a bar, at low order vertical resonances. In such a case the boxy "bulges" are parts of bars seen edge-on. For the three galaxies we study the families associated with the "peanut" or "X"-shape morphology are most probably bifurcations at the vertical 2/1 or 4/1 resonance.

description: Wurde die Entscheidung getroffen, dass ein Kind fremdplatziert wird, stellt sich für zuweisende Fachpersonen die Frage, ob ein Heim oder eine Pflegefamilie geeignet ist. Um dies herauszufinden, orientieren sich Fachpersonen mehrheitlich an eigenen Erfahrungen und an denjenigen ihres Teams. Ebenfalls einen hohen Stellenwert haben Gespräche mit der betroffenen Familie und weiteren involvierten Fachpersonen. Diesem Vorgehen gegenüber steht, dass sich durch eine standardisierte Vorgehensweise die Zuweisungsqualität verbessert. Es werden weniger Pflegeverhältnisse abgebrochen. Die vorliegende Bachelorarbeit beschäftigt sich mit der Frage: “Wann ist die Indikation für die Zuweisung von Kindern in eine Pflegefamilie gegeben?” Indikation meint die als notwendig und geeignet beurteilte Hilfe. Die Erkenntnisse werden in einer Liste zusammengefasst, welche Fachpersonen im Zuweisungsprozess als Orientierungshilfe dienen kann. Um die Forschungsfrage zu beantworten, wurden anhand eines Leitfadens neun qualitative Interviews durchgeführt. Sowohl mit fünf Fachpersonen, welche unterschiedliche Rollen im Zuweisungsprozess haben, wie auch mit zwei Pflegemüttern und zwei ehemaligen Pflegekindern. Es wurde ersichtlich, dass Pflegefamilien für viele Kinder geeignet sind und die föderalistischen Strukturen der Schweiz das komplexe Pflegekinderwesen zusätzlich verkomplizieren. Ausserdem zeigte sich die Wichtigkeit guter Begleitung, welche die Tragfähigkeit von Pflegefamilien erhöht. Aufgrund dieser Ergebnisse kann vermutet werden, dass eine Vereinheitlichung des Pflegekinderwesens und die Finanzierung qualitativ hochwertiger Begleitung mehr gelingende Pflegeverhältnisse ermöglichen würde.

description: We investigate the formation of nanogaps in gold wires due to electromigration. We show that the breaking process will not start until a local temperature of typically 400 K is reached by Joule heating. This value is rather independent of the temperature of the sample environment (4.2-295 K). Furthermore, we demonstrate that the breaking dynamics can be controlled by minimizing the total series resistance of the system. In this way, the local temperature rise just before break down is limited and melting effects are prevented. Hence, electrodes with gaps < 2 nm are easily made, without the need of active feedback. For optimized samples, we observe quantized conductance steps prior the gap formation.

The Bogomol'nyi limit appears and the corresponding solutions are given by the static-soliton configurations. Solitons from different families are localized at the same place. They behave like a paired hole and lump on the top of the uniform vacuum condensates, depending on the values of the coupling strengths. When the number of particles in the first family is much larger than that of the second family, the hole solution goes to the vortex profile already found in the one-family Calogero model.

description: Recent statistical deconvolution methods have produced extended kinematical maps in a range of heliocentric distances that are a factor of two to three larger than those analysed in the Gaia Collaboration based on the same data. In this paper, we use such maps to derive the rotation curve both in the Galactic plane and in off-plane regions and to analyse the density distribution. By assuming stationary equilibrium and axisymmetry, we used the Jeans equation to derive the rotation curve. Then we fit it with density models that include both dark matter and predictions of the MOND (Modified Newtonian dynamics) theory. Since the Milky Way exhibits deviations from axisymmetry and equilibrium, we also considered corrections to the Jeans equation. To compute such corrections, we ran N-body experiments of mock disk galaxies where the departure from equilibrium becomes larger as a function of the distance from the centre. The rotation curve in the outer disk of the Milky Way that is constructed with the Jeans equation exhibits very low dependence on $R$ and $z$ and it is well-fitted both by dark matter halo and MOND models. The application of the Jeans equation for deriving the rotation curve, in the case of the systems that deviate from equilibrium and axisymmetry, introduces systematic errors that grow as a function of the amplitude of the average radial velocity. In the case of the Milky Way, we can observe that the amplitude of the radial velocity reaches $\sim 10\%$ that of the azimuthal one at $R\approx 20$ kpc. Based on this condition, using the rotation curve obtained from the Jeans equation to calculate the mass may overestimate its measurement.

In this contribution we present the first systematic study of the IntraCluster Light (ICL) for a statistically representative sample (Zibetti et al. 2005), which comprises 683 clusters selected between z=0.2 and 0.3 from ~1500 deg^2 in the SDSS. Their ICL is studied by stacking the images in the g-, r-, and i-band after masking out all galaxies and polluting sources. In this way a very uniform background illumination is obtained, that allows us to measure surface brightnesses as faint as 31 mag/arcsec^2 and to trace the ICL out to 700 kpc from the central galaxy. We find that the local fraction of light contributed by intracluster stars rapidly decreases as a function of the clustercentric distance, from ~40% at 100 kpc to ~5% at 500 kpc. By comparing the distribution and colours of the ICL and of the clusters galaxies, we find indication that the main source of ICL are the stars stripped from galaxies that plunge deeply into the cluster potential well along radial orbits. Thus, if dEs are the remnants of these stripped progenitors we should expect similar radial orbital anisotropies and correlations between the dE luminosity function and the amount of ICL in different clusters. The diffuse emission we measure is contaminated by faint unresolved galaxies: this makes our flux estimate depend to some extent on the assumed luminosity function, but, on the other hand, allows us to constrain the number of faint galaxies. Our present results disfavour steep (alpha

description: In the influence maximization (IM) problem, we are given a social network and a budget $k$, and we look for a set of $k$ nodes in the network, called seeds, that maximize the expected number of nodes that are reached by an influence cascade generated by the seeds, according to some stochastic model for influence diffusion. In this paper, we study the adaptive IM, where the nodes are selected sequentially one by one, and the decision on the $i$th seed can be based on the observed cascade produced by the first $i-1$ seeds. We focus on the full-adoption feedback in which we can observe the entire cascade of each previously selected seed and on the independent cascade model where each edge is associated with an independent probability of diffusing influence. Our main result is the first sub-linear upper bound that holds for any graph. Specifically, we show that the adaptivity gap is upper-bounded by $\lceil n^{1/3}\rceil $, where $n$ is the number of nodes in the graph. Moreover, we improve over the known upper bound for in-arborescences from $\frac{2e}{e-1}\approx 3.16$ to $\frac{2e^2}{e^2-1}\approx 2.31$. Finally, we study $α$-bounded graphs, a class of undirected graphs in which the sum of node degrees higher than two is at most $α$, and show that the adaptivity gap is upper-bounded by $\sqrtα+O(1)$. Moreover, we show that in 0-bounded graphs, i.e. undirected graphs in which each connected component is a path or a cycle, the adaptivity gap is at most $\frac{3e^3}{e^3-1}\approx 3.16$. To prove our bounds, we introduce new techniques to relate adaptive policies with non-adaptive ones that might be of their own interest.

description: Resettlement-Flüchtlinge (RFL) zählen aufgrund ihrer biografischen und traumatischen Erfahrungen zu einer vulnerablen Gruppe, weshalb sie mit dem Resettlement-Programm besonderen Schutz erhalten. Für den Aufbau eines eigenständigen Lebens im Aufnahmeland und die Traumabewältigung benötigen RFL-Familien professionelle Unterstützung. Diese Bachelorarbeit befasst sich mit traumapädagogischen Handlungsansätzen für die Sozialpädagogische Familienbegleitung (SPF) in ihrer Arbeit mit RFL. Aufgrund ihrer Arbeits- und Handlungsprinzipien und dem Wissen über zentrale Aspekte der Traumapädagogik könnte die SPF ein adäquates Unterstützungsangebot für RFL-Familien sein. Die Traumapädagogik findet dabei auf individueller und systemischer Ebene statt, wobei die Elternarbeit und die Stärkung der Erziehungskompetenzen zentral sind. Die erfolgreiche Zusammenarbeit mit RFL basiert insbesondere auf einer traumasensiblen Grundhaltung und der Beziehungsarbeit. Dazu kommen weitere traumapädagogische Inhalte wie der Realitätsbezug, die Partizipation und Transparenz sowie das Schaffen von Strukturen und Dialogangeboten. Ebenfalls können Professionelle der SPF verlässliche Beziehungen, sichere Orte und Selbstbemächtigung fördern und RFL in der Ressourcenerschliessung und Netzwerkarbeit unterstützen. Seitens der Professionellen sind interkulturelle Kompetenzen sowie Selbstfürsorge und Selbstreflexion notwendig. Abschliessend sind institutionelle Rahmenbedingungen, wie Weiterbildungsangebote für den Aufbau von traumaspezifischem Wissen oder die Möglichkeit zu interdisziplinärer Zusammenarbeit für eine professionelle Begleitung von RFL wichtig.

description: This paper presents the possibilities of using the Unity engine to create the research software for cognitive neuroscience using the brain-to-brain synchrony paradigm. Neurofeedback software for neuroscience research in the brain-to-brain synchrony paradigm is represented by software that allows to implement three research protocols based on the EEG signals recording: the “eyes-to-picture” in the double glasses HTC VIVE PRO protocol, the “eyes-to-eyes” / “face-to-face” protocol and the “eyes-to-screens” protocol. The presented brain-to-brain synchrony software solution for the implementation of different protocols is a digital platform allowing to perform hyperscanning of electrical activity of the cerebral cortex simultaneously in several persons and thus study the functions of higher neural networks of socially determined areas of the cerebral cortex.

description: Im Rahmen der Forschungsarbeit ‹Sozialräumliche Gemeindeentwicklung› befassen sich Jelena Jankovic und Florian Frey mit der Frage, welche Funktionen und Positionen die Soziokulturelle Animation (SKA) in sozialräumlichen Entwicklungsprozessen auf kommunaler Ebene einnehmen kann. Diese Arbeit richtet sich an Fachpersonen der SKA, aber auch an staatliche und gesellschaftliche Akteurinnen und Akteure, welche sich mit der Entwicklung von kommunalen Räumen befassen. Als Basis für die Forschung in dieser Bachelorarbeit dienen relevante Theorien von Raum und Raumentwicklung. Aufbauend werden die räumlichen und strukturellen Gegebenheiten der Gemeinde Allschwil mit der Governance-Perspektive als Analyseinstrument verdeutlicht. Der Forschungsteil untersucht mittels leitfadengestützten Experteninterviews die wesentlichen Faktoren und Akteurinnen/Akteure, welche die sozialräumliche Gemeindeentwicklung beeinflussen. Es zeigte sich eine zunehmende Bedeutung der sozialräumlichen Entwicklung auf kommunaler Ebene. Der Siedlungsverdichtung können Gemeinden nur qualitativ begegnen, wenn sie sozialen Aspekten in der räumlichen Entwicklung die nötige Bedeutung zuschreiben. Vor diesem Hintergrund hat die Autorenschaft förderliche und hinderliche Eigenschaften für die sozialräumliche Entwicklung benannt und den Handlungsbedarf für die SKA auf kommunaler Ebene abgeleitet. Dabei geht es vor allem darum, dass die SKA einen kritischen Blick auf die staatlichen Ziele, Strukturen und Prozesse richtet und mit den soziokulturellen Handlungsansätzen zwischen Lebenswelt und System vermitteln kann.

description: The focus point region of supersymmetric models is compelling in that it simultaneously features low fine-tuning, provides a decoupling solution to the SUSY flavor and CP problems, suppresses proton decay rates and can accommodate the WMAP measured cold dark matter (DM) relic density through a mixed bino-higgsino dark matter particle. We present the focus point region in terms of a weak scale parameterization, which allows for a relatively model independent compilation of phenomenological constraints and prospects. We present direct and indirect neutralino dark matter detection rates for two different halo density profiles, and show that prospects for direct DM detection and indirect detection via neutrino telescopes such as IceCube and anti-deuteron searches by GAPS are especially promising. We also present LHC reach prospects via gluino and squark cascade decay searches, and also via clean trilepton signatures arising from chargino-neutralino production. Both methods provide a reach out to m_{\tg}\sim 1.7 TeV. At a TeV-scale linear e^+e^- collider (LC), the maximal reach is attained in the \tz_1\tz_2 or \tz_1\tz_3 channels. In the DM allowed region of parameter space, a \sqrt{s}=0.5 TeV LC has a reach which is comparable to that of the LHC. However, the reach of a 1 TeV LC extends out to m_{\tg}\sim 3.5 TeV.

description: The increasing reliance on applications with machine learning (ML) components calls for mature engineering techniques that ensure these are built in a robust and future-proof manner. We aim to empirically determine the state of the art in how teams develop, deploy and maintain software with ML components. We mined both academic and grey literature and identified 29 engineering best practices for ML applications. We conducted a survey among 313 practitioners to determine the degree of adoption for these practices and to validate their perceived effects. Using the survey responses, we quantified practice adoption, differentiated along demographic characteristics, such as geography or team size. We also tested correlations and investigated linear and non-linear relationships between practices and their perceived effect using various statistical models. Our findings indicate, for example, that larger teams tend to adopt more practices, and that traditional software engineering practices tend to have lower adoption than ML specific practices. Also, the statistical models can accurately predict perceived effects such as agility, software quality and traceability, from the degree of adoption for specific sets of practices. Combining practice adoption rates with practice importance, as revealed by statistical models, we identify practices that are important but have low adoption, as well as practices that are widely adopted but are less important for the effects we studied. Overall, our survey and the analysis of responses received provide a quantitative basis for assessment and step-wise improvement of practice adoption by ML teams.
