description: Inspired by the allure of additive fabrication, we pose the problem of origami design from a new perspective: how can we grow a folded surface in three dimensions from a seed so that it is guaranteed to be isometric to the plane? We solve this problem in two steps: by first identifying the geometric conditions for the compatible completion of two separate folds into a single developable four-fold vertex, and then showing how this foundation allows us to grow a geometrically compatible front at the boundary of a given folded seed. This yields a complete marching, or additive, algorithm for the inverse design of the complete space of developable quad origami patterns that can be folded from flat sheets. We illustrate the flexibility of our approach by growing ordered, disordered, straight and curved folded origami and fitting surfaces of given curvature with folded approximants. Overall, our simple shift in perspective from a global search to a local rule has the potential to transform origami-based meta-structure design.
Glazial übertiefte Talabschnitte in den Bayerischen Alpen: Ergebnisse glazialgeologischer, hydrologischer und geophysikalischer Untersuchungen

description: In den Tälern der Bayerischen Alpen treten abschnittsweise glaziale Längsübertiefungen auf. Diese Übertiefungen sind an Gesteine gebunden, die von Natur aus leicht erodierbar sind; sie treten aber auch in schwer erodierbaren Gesteinen auf, wenn sie intensiv zerklüftet sind und wenn diese Kluftzonen durch die wiederholte Be- und Entlastung des Gebirges im Zuge des wiederholten Vor- und Zurückweichens der Gletscher aufgelockert wurden. Die glaziale Übertiefung beträgt sehr häufig 200 bis 300 m ab heutiger Talhöhe. Wo es zusätzlich zu einer Vereinigung zweier Gletscherströme kam, liegen höhere Übertiefungsbeträge vor. Den Abschluß der Übertiefung bilden Schwellen, die teilweise aus der Talfläche herausragen, teilweise in 150 m unter Flur liegen. Die Talübertiefung scheint rißeiszeitlich ihr größtes Ausmaß erlangt zu haben. Die Talfüllung besteht ganz überwiegend aus wenig wasserwegsamen Lockergesteinen, wie Tonen und Moränen mit hohem Feinkornanteil; sie setzt sich in großflächiger Verbreitung wohl nur aus riß-und würmeiszeitlichen Anteilen zusammen.

description: Nonlinear reformulations of the spectral clustering method have gained a lot of recent attention due to their increased numerical benefits and their solid mathematical background. We present a novel direct multiway spectral clustering algorithm in the $p$-norm, for $p \in (1, 2]$. The problem of computing multiple eigenvectors of the graph $p$-Laplacian, a nonlinear generalization of the standard graph Laplacian, is recasted as an unconstrained minimization problem on a Grassmann manifold. The value of $p$ is reduced in a pseudocontinuous manner, promoting sparser solution vectors that correspond to optimal graph cuts as $p$ approaches one. Monitoring the monotonic decrease of the balanced graph cuts guarantees that we obtain the best available solution from the $p$-levels considered. We demonstrate the effectiveness and accuracy of our algorithm in various artificial test-cases. Our numerical examples and comparative results with various state-of-the-art clustering methods indicate that the proposed method obtains high quality clusters both in terms of balanced graph cut metrics and in terms of the accuracy of the labelling assignment. Furthermore, we conduct studies for the classification of facial images and handwritten characters to demonstrate the applicability in real-world datasets.

description: Methods and techniques are described for automated measurements of greenhouse gases (GHGs) in both the laboratory and the field. Robotic systems are currently available to measure the entire range of gases evolved from soils including dinitrogen (N2). These systems usually work on an exchange of the atmospheric N2 with helium (He) so that N2 fluxes can be determined. Laboratory systems are often used in microbiology to determine kinetic response reactions via the dynamics of all gaseous N species such as nitric oxide (NO), nitrous oxide (N2O), and N2. Latest He incubation techniques also take plants into account, in order to study the effect of plant-soil interactions on GHGs and N2 production. The advantage of automated in-field techniques is that GHG emission rates can be determined at a high temporal resolution. This allows, for instance, to determine diurnal response reactions (e.g. with temperature) and GHG dynamics over longer time periods.
title: An executive role study: investigating expectation enactment in the role of the chancellor of the University of the Nations-Kona
Creators: name: Early, Gene
Publisher: name: The Open University
Year: 2000

description: This research created an Expectation Enactment Analysis, which was used to study the Chancellor of a Christian, faith-based, missions-oriented university. The study was grounded in the field of managerial work, jobs, and behaviour. It also drew on symbolic interactionism, role theory, role identity theory, and enactment theory. The framework for Expectation Enactment Analysis contains seven components viewed from three perspectives. The components are 1) identification of contextual parameters, 2) Role Episode analyses, 3) interviews of the Chancellor and his Role Set Members, 4) identification of Managerial Agenda items, tasks, and activities, 5) identification of three Expectation Enactment Programs, 6) expectations enacted, and 7) Impact Analysis. The three perspectives are organizational, interpersonal, and personal. This Analysis developed the Expectation Enactment Program model-an open systems, role construct--integrating the managerial agenda as an internal standard for internal processing and external performance. Additionally, the Analysis linked external performance to expectation enactment and the Role Incumbent's impact on the organization, his Role Set Members, and himself. The study employed a naturalistic, "inquiry from the inside" approach characterised by a longitudinal, field based, case study format relying on qualitative methods. It was an exploratory study designed to create a conceptual framework for further developing an understanding of managerial roles. This methodology involved intensive participation on the part of the researcher. As a result, it extends this type of research only occasionally seen in the field of managerial work, jobs, and behaviour. Expectation Enactment Analysis integrates work from a breadth of related disciplines. Such an Analysis offers the possibility of understanding 1) the functioning of a Role Incumbent in role, 2) the impact of that functioning on an organization, Role Set Members, and him/herself, and 3) potential leverage points for creating change within the organization through the Role Incumbent. The Analysis offers future possibilities for application in research, management education, and executive development.

description: In mathematics education, there is general agreement regarding the significance of mathematical literacy (also quantitative literacy or numeracy) for informed citizenship, which often requires evaluating the use of numbers in public policy discourse. We hold that such an evaluation must accommodate the necessarily fragile relation between the information that numbers are taken to carry and the policy decisions they are meant to support. In doing so, attention needs to be paid to differences in how that relation is formed. With this in mind, we investigated a public discourse that heavily relied on numbers in the context of introducing, maintaining, and easing the rules and regulations directed to contain the spread of the virus SARS-CoV-2 during the first epidemic wave of COVID-19 in Germany with its peak in early April 2020. We used a public-service broadcasting outlet as data. Our theoretical stance is affiliated with post-structuralist discourse theory. As an outcome, we identified four major related strategies of using numbers, which we named rationalisation, contrast, association and recharging. In our view explicit attention to these strategies as well as identifying new ones can aid the task of furthering critical mathematical literacy.

description: The existence of a structural gender gap in agriculture is commonly recognized. Solutions for overcoming this are often argued to bring about greater gender equality and increased agricultural production. Programs such as AWARD place gender equality high on their agenda, as they attempt to reduce the gap by supporting the career development of women in agricultural science research fields, while also taking stand on current international development narratives on the urgency to invest in agricultural research. Using ecofeminist theories, this paper contends that while such programs’ approach to overcoming the gaps in agriculture and science is seemingly focused on women’s empowerment, the risk exists that it could result in the reinforcement of an already dominant knowledge, constructed over centuries of inequality. A proposal is formulated to allow for the emergence and recognition of gender epistemological needs, and for feminist epistemological discourses to challenge the ethical premises, research priorities, approach, and methods of current internationally funded agricultural research for development.

description: This paper builds on the work of the African Women in Agricultural Research and Development program to demonstrate the potentially crucial role of Social Network Analysis techniques for measuring the effectiveness of women’s empowerment programs in African agricultural research and development. Concepts of social capital formation and communities of practice permeate many theories of change which seek empowerment outcomes. Interlaced within these concepts is the abstract notion of relationships between stakeholders, be they human, institutional, or otherwise. Social Network Analysis is a powerful set of methods which permits the integration of data on relationships into conventional statistical techniques. This paper provides a practical introduction to the theory and practice of using Social Network Analysis in concert with other monitoring and evaluation methods to inform decision-making. Throughout the paper, concrete examples from the African Women in Agricultural Research and Development program experience, specifically patterns of professional association membership among fellows, illuminate key concepts, practices, and recommendations.
title: Economic Evaluations of Companion Cancer Biomarkers for Targeted Therapies
Creators: name: Seo, MK
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2020

description: Background: Companion biomarkers for targeted therapies have increased the expectation that biomarkers can improve health outcomes or potentially save health resources without compromising patient outcomes. However, few countries provide health economic assessment methods guidance (e.g. health technology assessment guide) specifically for co-dependent technologies such as companion diagnostics. Aim: This thesis aims to explore good practices for evaluating companion biomarker tests as part of health economic assessments of their co-dependent targeted therapies in cancer. Scope of the study: Cancer biomarkers for targeted therapies investigated in this thesis are restricted to companion biomarkers, classifying patients into responders and non-responders for a specific targeted therapeutic agent. Methods: Four research activities were designed: two systematic literature reviews (SLR) and two health economic models. The first SLR (Chapter 2) was conducted to demonstrate the impact of companion biomarker tests on the cost-effectiveness of targeted therapies, focusing on metastatic colorectal cancer (mCRC). The second SLR (Chapter 3) considered all cancer areas. It investigated current and best practice for modelling and incorporating companion biomarker tests when assessing the cost-effectiveness of targeted cancer therapies. The findings from these two SLRs were then applied to the cost-effectiveness modelling of a novel candidate companion biomarker test, Heat Shock Protein 27 (HSP27) expression (Chapter 4). The final work (Chapter 5) developed a practical guide to modelling companion biomarker tests as part of economic evaluations of corresponding targeted therapies; a global model was constructed and provided as a worked example coupled with step-by-step guide for readers to follow. Results: The first SLR study showed that the use of companion biomarker tests saved some costs however, the saving was not high enough to change materially the cost-effectiveness of co-dependent therapeutic agents. The second SLR found that there was inconsistency in the methods for evaluating companion biomarker tests in the appraisal of co-dependent agents. The cost-effectiveness analysis of HSP27 expression showed conflicting results depending on the structure of the comparative analysis. Finally, the modelling guide coupled with a worked example of a global model demonstrated how to model characteristics of companion biomarker tests in economic evaluations of test-guided therapies. Conclusion: This thesis highlights the need to reach a consensus on the methods of evaluating companion testing technologies as part of economic evaluations of their corresponding test-guided therapies. Built upon the consensus, a methods guide for co-dependent technologies needs to be developed and introduced, providing a coherent and unified guidance on good practices, reference case, evidentiary standards and data requirements for economic evaluations.

description: A sophisticated coupled-channel analysis is presented that combines different processes: the channels $π^0π^0η$, $π^0ηη$ and $K^+K^-π^0$ from $\bar{p}p$ annihilations, the P- and D-wave amplitudes of the $πη$ and $πη^\prime$ systems produced in $π^- p$ scattering, and data from $ππ$-scattering reactions. Hence our analysis combines the data sets used in two independent previous analyses published by the Crystal Barrel experiment and by the JPAC group. Based on the new insights from these studies, this paper aims at a better understanding of the spin-exotic $π_1$ resonances in the light-meson sector. By utilizing the K-matrix approach and realizing the analyticity via Chew-Mandelstam functions the amplitude of the spin-exotic wave can be well described by a single $π_1$ pole for both systems, $πη$ and $πη^\prime$. The mass and width of the $π_1$-pole are measured to be $(1623 \, \pm \, 47 \, ^{+24}_{-75}\,)\, \mathrm{MeV/c}^2$ and $(455 \, \pm \, 88 \, ^{+144}_{-175}\,)\, \mathrm{MeV}$.

description: Aims: To describe healthcare utilization and cost associated with the short-term and long-term complications of cystectomy among commercially insured bladder cancer patients in the United States. Materials and methods: This retrospective, observational cohort study evaluated adults with bladder cancer receiving a transurethral resection of bladder tumor followed by a partial or radical cystectomy procedure using U.S. administrative claims from the 2005–2015 IBM MarketScan Commercial and Medicare Supplemental databases. Bladder cancer patients were classified into two cohorts: partial cystectomy or radical cystectomy. Cystectomy complications were identified during the cystectomy admission, short-term period, and long-term period. Complication-related utilization and cost outcomes were reported in aggregate during the cystectomy admission and per patient per month (PPPM) during the short-term and long-term follow-up periods. Results: Of 5136 patients who received a cystectomy, 488 (9.5%) received partial cystectomy and 4648 (90.5%) received radical cystectomy. The mean (SD) costs of complications during the cystectomy admission were $11,728 ($43,380) for radical cystectomy and $4657 ($25,668) for partial cystectomy. In the short-term period, PPPM complication-related healthcare costs were $638 [$3793] for partial cystectomy and $2681 [$14,705] for radical cystectomy. In the long-term period, PPPM complication-related healthcare costs were $544 [$2580] for partial cystectomy and $1619 [$7874] for radical cystectomy. Conclusions: Cystectomy-related complications, especially with radical cystectomy, present a substantial financial burden to patients and payers immediately after surgery as well as in the long term. Targeted interventions which improve clinical outcomes but reduce substantial costs associated with cystectomy for bladder cancer are needed.

description: The reduced dynamics of a central spin coupled to a bath of N spin-1/2 particles arranged in a spin star configuration is investigated. The exact time evolution of the reduced density operator is derived, and an analytical solution is obtained in the limit of an infinite number of bath spins, where the model shows complete relaxation and partial decoherence. It is demonstrated that the dynamics of the central spin cannot be treated within the Born-Markov approximation. The Nakajima-Zwanzig and the time-convolutionless projection operator technique are applied to the spin star system. The performance of the corresponding perturbation expansions of the non-Markovian equations of motion is examined through a comparison with the exact solution.

description: There are recent interests with CsI(Tl) scintillating crystals for Dark Matter experiments. The key merit is the capability to differentiate nuclear recoil (nr) signatures from the background $β/ γ$-events due to ambient radioactivity on the basis of their different pulse shapes. One of the major experimental challenges is to perform such pulse shape analysis in the statistics-limited domain where the light output is close to the detection threshold. Using data derived from measurements with low energy $γ$'s and nuclear recoils due to neutron elastic scatterings, it was verified that the pulse shapes between $β/ γ$-events are different. Several methods of pulse shape discrimination are studied, and their relative merits are compared. Full digitization of the pulse shapes is crucial to achieve good discrimination. Advanced software techniques with mean time, neural network and likelihood ratios give rise to satisfactory performance, and are superior to the conventional Double Charge method commonly applied at higher energies. Pulse shape discrimination becomes effective starting at a light yield of about 20 photo-electrons. This corresponds to a detection threshold of about 5 keV electron-equivalence energy, or 40$-$50 keV recoil kinetic energy, in realistic experiments.

description: We consider a linear system that consists of a linear wave equation on a horizontal hypersurface and a parabolic equation in the half space below. The model describes longitudinal elastic waves in organic monolayers at the water–air interface, which is an experimental setup that is relevant for understanding wave propagation in biological membranes. We study the scaling regime where the relevant horizontal length scale is much larger than the vertical length scale and provide a rigorous limit leading to a fractionally damped wave equation for the membrane. We provide the associated existence results via linear semigroup theory and show convergence of the solutions in the scaling limit. Moreover, based on the energy–dissipation structure for the full model, we derive a natural energy and a natural dissipation function for the fractionally damped wave equation with a time derivative of order 3/2.
title: The role of coping strategies in people who have psoriasis: an investigation and pilot intervention
Creators: name: Hill, Laura
Publisher: name: The Open University
Year: 1999

description: This project consisted of a two pronged investigation into the role of coping strategies in psoriasis - a chronic, relapsing skin condition associated with impoverished quality of life and substantial psychological distress. The first study examined the relative influence of coping strategies on sufferers' subjective disability and psychological distress. The second study explored the efficacy of a pilot group intervention based on the format of Coping Effectiveness Training. Study one utilised the theory of Appraisal and Coping (Lazarus & Folkman, 1984) to investigate the role of coping strategies in mediating sUbjective disability and psychological distress in 89 psoriasis sufferers. Empirical definitions of adaptive and maladaptive coping strategies were used to categorise coping. Maladaptive coping strategies, in particular venting emotions and mental disengagement, were significantly associated with both subjective disability and psychological distress, accounting for a greater proportion of the variance on these measures than age, gender or duration of psoriasis. Adaptive coping strategies were not inversely associated with the outcome measures. Study two piloted a group based intervention derived from Coping Effectiveness Training - a structured problem focused group - with a self selected community sample of 16 psoriasis sufferers. While the intervention did not yield significant changes on outcome measures relative to the control group, there was a trend for a reduction in subjective disability. Participant feedback suggested that the intervention was felt to be useful and that specific coping techniques had been acquired as a result of the intervention. Implications are discussed in terms of the roles of coping strategies and the use of structured group interventions in psoriasis, and suggestions for future research are outlined.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Inland waters receive and process large amounts of colored organic matter from the terrestrial surroundings. These inputs dramatically affect the chemical, physical, and biological properties of water bodies, as well as their roles as global carbon sinks and sources. However, manipulative studies, especially at ecosystem scale, require large amounts of dissolved organic matter with optical and chemical properties resembling indigenous organic matter. Here, we compared the impacts of two leonardite products (HuminFeed and SuperHume) and a freshly derived reverse osmosis concentrate of organic matter in a set of comprehensive mesocosm- and laboratory-scale experiments and analyses. The chemical properties of the reverse osmosis concentrate and the leonardite products were very different, with leonardite products being low and the reverse osmosis concentrate being high in carboxylic functional groups. Light had a strong impact on the properties of leonardite products, including loss of color and increased particle formation. HuminFeed presented a substantial impact on microbial communities under light conditions, where bacterial production was stimulated and community composition modified, while in dark potential inhibition of bacterial processes was detected. While none of the browning agents inhibited the growth of the tested phytoplankton Gonyostomum semen, HuminFeed had detrimental effects on zooplankton abundance and Daphnia reproduction. We conclude that the effects of browning agents extracted from leonardite, particularly HuminFeed, are in sharp contrast to those originating from terrestrially derived dissolved organic matter. Hence, they should be used with great caution in experimental studies on the consequences of terrestrial carbon for aquatic systems.
Fast Distance-based Anomaly Detection in Images Using an Inception-like Autoencoder

description: The goal of anomaly detection is to identify examples that deviate from normal or expected behavior. We tackle this problem for images. We consider a two-phase approach. First, using normal examples, a convolutional autoencoder (CAE) is trained to extract a low-dimensional representation of the images. Here, we propose a novel architectural choice when designing the CAE, an Inception-like CAE. It combines convolutional filters of different kernel sizes and it uses a Global Average Pooling (GAP) operation to extract the representations from the CAE's bottleneck layer. Second, we employ a distanced-based anomaly detector in the low-dimensional space of the learned representation for the images. However, instead of computing the exact distance, we compute an approximate distance using product quantization. This alleviates the high memory and prediction time costs of distance-based anomaly detectors. We compare our proposed approach to a number of baselines and state-of-the-art methods on four image datasets, and we find that our approach resulted in improved predictive performance.

title: The Zapatista discursive war : literary subversion in Subcomandante Marcos' writings (1994-2017)
Creators: name: Gribomont, Isabelle
Publisher: name: University of St Andrews
Year: 2019

description: This doctoral thesis argues that Subcomandante Marcos’ appropriations of existing textual material, whether they take the form of quotations, allusions, parodies or remixes, are key to the discursive war waged in the communiqués. Through these textual manipulations, Marcos simultaneously promotes inter-epistemic dialogues and questions colonial knowledge to favour the Zapatistas’ anti-neoliberal and decolonial political agenda. The thesis begins by contextualising the emergence of the EZLN within the history of Chiapas since the nineteenth century, providing background information on Marcos’ communiqués, and engaging with relevant scholarship. The subsequent literary analyses uncover some of the textual strategies which contribute to the Zapatistas’ transcultural communication on the one hand, and their subversive political message on the other. It argues that Marcos recuperates Jorge Luis Borges’ translation strategies and his irreverent approach towards authorship to challenge the Mexican political class and colonial cultural hierarchies through intertextual allusions to the Western literary tradition. Simultaneously, Marcos creates bridges between Maya and Western epistemological systems. To do so, he relies on certain motifs prevalent in both Maya culture and idealist philosophy. In addition to being deployed as a bridging element, idealist philosophy, alongside postmodernity, is recuperated by Marcos for its inherent scepticism, which is redirected towards the narratives supporting the Mexican government and its neoliberal policies. Moreover, the staging of cynical voices in Marcos’ writings is understood as a rhetorical device which places the Zapatistas in moral opposition to the Mexican government. Finally, it is argued that Marcos’ recent digital turn mirrors the Zapatistas’ interest for digital activism and their ambiguous appropriation of Western technology, simultaneously perceived as a site of colonial oppression and a subversive space. These findings highlight Marcos’ discursive intervention in the global cultural fabric, afforded by his deliberate displacement of specific texts and the cultural contexts they embody.

description: Studies of hyper-arid sites contribute to our understanding on how life adapted to extreme conditions. They are often used to further deduce implications for extraterrestrial biology by the so-called analogue site-approach. The Atacama Desert, Chile, is one of the most prominent analogue sites despite its neighboring productive ecosystems due to its hyper-aridity and geochemical features resembling Martian environments. We hypothesize that many drivers of extremophile life in analogue sites are only mistakenly attributed to aridity alone, thus obscuring a clear view of the far more complex process interactions originating in nearby earthly ecosystems. To test this, we investigated 54 soil profiles up to 60 cm of soil depth along of four transects in the Atacama Desert, either running parallel (S-N) or perpendicular (W-E) to the Andes. Our objective was to reveal the processes controlling the formation of soil organic carbon (SOC) as the most reliable proxy for microbial life in order to understand the boundary conditions of life in extreme habitats. Further, we aimed at identifying analogue sites as uncompromised as possible by external influences of for example, vegetated or marine ecosystems. We found a mixture of influences driving habitable conditions on gradients perpendicular to the Andes, for example, fog and precipitation scavenging caused by altitudinal variations and differing proximity to the Pacific Ocean, while transects parallel to the Andes were much less biased by external factors. Our results show that studies on life under extreme conditions should clarify the explanatory strength of the investigated factors by a gradient study approach.

description: This paper shares the challenges that small, socially disadvantaged Alabama vegetable and fruit producers in Alabama faced and overcame to secure their USDA Produce Good Agricultural Practices (GAPs) food safety certification. The commercial buyers, collaborating with the Small Farmers Agricultural Cooperative (SFAC) producers, required the producers to be certified. This certification was based on the regulated security standards for food safety, the Harmonized Food Safety Standards with the Global Addendum (Global Markets Primary Production Assessments). This venture entailed the integrated resource approach, which comprised experts from Tuskegee University (Extension and Research staff) working closely with SFAC producers. Additional support and experiential guidance was provided by other collaborating partners: Walmart, Lipman Produce, WP Rawls, Pura Vida, C.H. Robinson, Federal and State Auditors, and the USDA (Strike Force Initiative). The collaborative efforts led to the producers successfully obtaining their GAP certification and fulfilling their contractual agreement obligations, despite the unexpected challenges.

description: Suppose that $L$ is one of the finite simple groups $PSL_4(q)$ or $PSU_4(q)$ and $L$ acts on a vector space $W$ over a field whose characteristic divides $q$. We prove that the natural semidirect product of $W$ and $L$ contains an element whose order differs from the order of any element of $L$, thus answering questions 14.60 and 17.73 (a) of the Kourovka Notebook.

description: The COoler SYnchrotron COSY-Jülich delivers phase-space cooled, polarized proton and deuteron beams with momenta up to p=3.65 GeV/c. Various experiments on hadron-induced strangeness production on proton, neutron and nuclear targets have been carried out. Here we report about recent results on associated strangeness production in pp -> KYN (Y= Lambda,Sigma) reactions, on K^+ production in pn collisions, and on K K-bar pair production in pp interactions. We also briefly discuss possible measurements to disentangle the parity of the recently discovered pentaquark state Theta^+, the spin dependence of the YN interaction, as well as planned experiments which aim at the determination of the a_0-f_0 mixing matrix element, a quantity which is believed to be sensitive to the nature of the light scalar mesons a_0/f_0(980).

description: We show for Germany that labor productivity as reflected in wage is, ceteris paribus, higher for workers who previously acquired work experience in rather urban labor markets with a large local workforce than in rather rural labor markets which are small in terms of regional employment. Our empirical analysis provides new evidence on the magnitude of these dynamic agglomeration gains by estimating the elasticity of wages with regard to the (cumulated) size of the local labor markets in which workers acquired experience. It shows that this elasticity increases with the level of individual experience to more than 0.06 implying that today’s wage of a worker with 20 years of experience or more would be about four to five percent higher if the worker would have gained all his or her experience in local labor markets double the size of the labor markets in which he or she actually was working in the past. These identified dynamic agglomeration gains are supposed to be related to learning externalities. The analysis uses information on individual employment biographies and regional employment from 1975 onwards. The wage information refers to more than 300,000 entry wages of new employment relationships in Germany in the period 2005 to 2011. The depreciation of human capital is taken into account and that high-skilled workers presumably are the ones other workers learn the most from

description: Microorganisms acting as sinks for the greenhouse gas nitrous oxide (N2O) are gaining increasing attention in the development of strategies to control N2O emissions. Non-denitrifying N2O reducers are of particular interest because they can provide a real sink without contributing to N2O release. The bacterial strain under investigation (IGB 4-14T), isolated in a mesocosm experiment to study the litter decomposition of Phragmites australis (Cav.), is such an organism. It carries only a nos gene cluster with the sec-dependent Clade II nosZ and is able to consume significant amounts of N2O under anoxic conditions. However, consumption activity is considerably affected by the O2 level. The reduction of N2O was not associated with cell growth, suggesting that no energy is conserved by anaerobic respiration. Therefore, the N2O consumption of strain IGB 4-14T rather serves as an electron sink for metabolism to sustain viability during transient anoxia and/or to detoxify high N2O concentrations. Phylogenetic analysis of 16S rRNA gene similarity revealed that the strain belongs to the genus Flavobacterium. It shares a high similarity in the nos gene cluster composition and the amino acid similarity of the nosZ gene with various type strains of the genus. However, phylogenomic analysis and comparison of overall genome relatedness indices clearly demonstrated a novel species status of strain IGB 4-14T, with Flavobacterium lacus being the most closely related species. Various phenotypic differences supported a demarcation from this species. Based on these results, we proposed a novel species Flavobacterium azooxidireducens sp. nov. (type strain IGB 4-14T = LMG 29709T = DSM 103580T).
Implications of alpha-dystroglycan glycosylation in the proper assembly of the dystroglycan associated protein complex and the polarized distribution of the inwardly rectifying potassium channel, Kir4.1, and the water permeable channel, AQP4, in perivascular glia

description: The dystroglycan protein complex spans the plasma membrane and provides a link between the cytoskeleton and the extracellular matrix (ECM). Defective O-linked glycosylation of α-dystroglycan (α-DG) within the complex severs this link leading to a subset of muscular dystrophies known as the dystroglycanopathies. These are characterized by muscle weakness and degeneration as well as by brain and ocular defects of unknown etiology. In brain and retina, α-DG and ECM molecules are enriched at astrocytic domains abutting blood vessels where they may be involved in localizing the inwardly rectifying potassium channel, Kir4.1, and aquaporin channel, AQP4, to astrocytic endfeet. To investigate the role of ECM ligand-binding to glycosylated sites on α-DG in the polarized distribution of these channels in vivo, we used the Large [superscript] myd mouse, an accepted animal model for dystroglycanopathies. We found that Kir4.1 and AQP4 are lost from astrocytic endfeet in brain while significant labeling for these channels is still detected at analogous cell domains in retina. Furthermore, while both α- and β₁- syntrophins are lost from perivascular astrocytes in brain of the Large [superscript] myd mouse, labeling for β₁-syntrophin is still evident at parallel domains in retina. These findings show that while ligand-binding to glycosylated sites on α-DG in concert with α- and β₁-syntrophins is crucial for the polarized distribution of Kir4.1 and AQP4 to functional domains in brain, distinct mechanisms may contribute to their localization in retina.
