Renormalisation of ϕ^4-theory on noncommutative R^2 in the matrix base

description: As a first application of our renormalisation group approach to non-local matrix models [hep-th/0305066], we prove (super-)renormalisability of Euclidean two-dimensional noncommutative ϕ^4-theory. It is widely believed that this model is renormalisable in momentum space arguing that there would be logarithmic UV/IR-divergences only. Although momentum space Feynman graphs can indeed be computed to any loop order, the logarithmic UV/IR-divergence appears in the renormalised two-point function -- a hint that the renormalisation is not completed. In particular, it is impossible to define the squared mass as the value of the two-point function at vanishing momentum. In contrast, in our matrix approach the renormalised N-point functions are bounded everywhere and nevertheless rely on adjusting the mass only. We achieve this by introducing into the cut-off model a translation-invariance breaking regulator which is scaled to zero with the removal of the cut-off. The naive treatment without regulator would not lead to a renormalised theory.

Year: 2021

description: This work is part of a series of articles whose aim is to present teachers and students with theoretical notions useful for examining certain technical themes, concepts, or theories that form the basis of a wide-ranging business economic literature but are not specifically treated in it. Specifically, this article aims at highlighting the basic systemic notions needed to understand the logic of "permanent organizations" viewed as autopoietic, teleonomic, cognitive, and efficient systems. An elementary symbology is used to present the characteristics that define "for-business organizations", and, within this class, to distinguish the "for-profit" from the "not-for-profit organizations". The concepts of production and market efficiency are specified, and from these the notions of TEVA, TEVAP, TEVAM, and EVA are derived. The work concludes by linking the concept of "autopoiesis" to those of Intelligence, Learning, and Experience, which characterize the management of efficient organizations.

description: In this work the Lippmann-Schwinger equation is used to model seismic waves in strongly scattering acoustic media. We consider the Helmholtz equation, which is the scalar wave equation in the frequency domain with constant density and variable velocity, and transform it to an integral equation of the Lippmann-Schwinger type. To directly solve the discretized problem with matrix inversion is time-consuming, therefore we use iterative methods. The Born series is a well-known scattering series which gives the solution with relatively small cost, but it has limited use as it only converges for small scattering potentials. There exist other scattering series with preconditioners that have been shown to converge for any contrast, but the methods might require many iterations for models with high contrast. Here we develop new preconditioners based on randomized matrix approximations and hierarchical matrices which can make the scattering series converge for any contrast with a low number of iterations. We describe two different preconditioners; one is best for lower frequencies and the other for higher frequencies. We use the fast Fourier transform both in the construction of the preconditioners and in the iterative solution, and this makes the methods efficient. The performance of the methods are illustrated by numerical experiments on two 2D models.

Proxy War by African States, 1950-2010

Subjects: classificationCode: 4408

description: The low number of recognized interstate wars in Africa since 1950 suggests three interlinked (but false) conclusions i.e., that African states are uniquely pacifistic, that they are particularly constrained against waging interstate war, and that whatever wars do take place are of necessity occasioned by the failure to restrain violent internal challengers such as warlords, secessionists, or dissident political factions. In contrast to these positions, my extensive analyses of primary and secondary data on African wars clearly indicate that African states frequently deploy violent means against one another, albeit through armed intermediaries in multi-actor wars. African `multi-actor wars' are thus overwhelmingly proxy wars; and this, given the predominance of multi-actor wars in the African war record, merits the selection of proxy wars as the phenomenon of interest in the study of African wars from 1950 to 2010. In order to examine the nature of this form of war, and explain when, where and why the use of proxies by states against one another constitutes a compelling explanation of empirical reality, I constructed an original dataset of major African conflicts using conventional (i.e., theory-neutral) indicators of war during the period under examination. This `Events List' contains 27 unique conflicts featuring 101 partnerships between a sponsoring state and one or more intermediaries. For each of these conflicts and partnerships (i.e., levels of analysis for multi-actor war) I added data on relevant variables and deployed a two-stage mixed-methods design to test particular rival hypothesis against my own theoretical propositions about proxy war.

description: We consider the characterization and computation of H-infinity norms for a class of time-delay systems. It is well known that in the finite dimensional case the H-infinity norm of a transfer function can be computed using the connections between the corresponding singular value curves and the imaginary axis eigenvalues of a Hamiltonian matrix, leading to the established level set methods. We show a similar connection between the transfer function of a time-delay system and the imaginary axis eigenvalues of an infinite dimensional linear operator $\mathcal{L}_ξ^N$. Based on this result, we propose a predictor-corrector algorithm for the computation of the H-infinity norm. In the prediction step, a finite-dimensional approximation of the problem, induced by a spectral discretization of the operator $\mathcal{L}_ξ$, and an adaptation of the algorithms for finite-dimensional systems, allow to obtain an approximation of the H-infinity norm of the transfer function of the time-delay system. In the next step the approximate results are corrected to the desired accuracy by solving a set of nonlinear equations which are obtained from the reformulation of the eigenvalue problem for the linear infinite-dimensional operator $\mathcal{L}_ξ^N$ as a finite dimensional nonlinear eigenvalue problem. These equations can be interpreted as characterizations of peak values in the singular value plot. The effects of the discretization in the predictor step are fully characterized and the choice of the number of discretization points is discussed. The paper concludes with a numerical example and the presentation of the results of extensive benchmarking.

Diff erences in Power Structures Regarding Access to Natural Resources at the Village Level in Central Sulawesi (Indonesia)

description: The mountain forests of the Indonesian province of Central Sulawesi include core areas of the global Wallacea biodiversity “hotspot”. Remote sensing data indicated that deforestation rates around Central Sulawesi’s Lore-Lindu National Park differ more strongly between villages than could be explained by differences in the individual characteristics of the village households as assessed by quantitative village censuses. This setting provided the background for a study into inter-village differences in power structures regarding access to natural resources. Our results are abstracted from 3*10 semi-structured, qualitative interviews with key informants from the leading groups of autochthonous and migrant households of three contrasting villages. In village A, nearly feudal power relationships are exerted by a group of local “fi rst settler” families that dominate formal village leadership as well as the infl uential Council of Traditional Leaders (Lembaga Adat), and that restrict deforestation and land transactions. No such institutional restrictions exist in village C. Traditional power relationships are replaced by economic power based on petty capitalisttype production of the international agricultural commodity cocoa. Deforestation is much higher in village C. In village B, traditional institutions and power structures still appear in place although land transactions are less restricted than in village A, resulting also in high deforestation rates. While contrasting problematic social effects, our study highlights the potential effi cacy of traditional institutions in the regulation of access to resources.

description: Electronic Hanbury Brown Twiss correlations are discussed for geometries in which transport is along adiabatically guided edge channels. We briefly discuss partition noise experiments and discuss the effect of inelastic scattering and dephasing on current correlations. We then consider a two-source Hanbury Brown Twiss experiment which demonstrates strikingly that even in geometries without an Aharonov-Bohm effect in the conductance matrix (second-order interference), correlation functions can (due to fourth-order interference) be sensitive to a flux. Interestingly we find that this fourth-order interference effect is closely related to orbital entanglement. The entanglement can be detected via violation of a Bell Inequality in this geometry even so particles emanate from uncorrelated sources.

Among the quantities we study are the monopole density and the monopole screening length, the static potential and the profile of the color electric flux tube. We furthermore derive the low-energy effective monopole action. Marked differences between the quenched and dynamical vacuum are found.

On the classical limit of the hyperbolic quantum mechanics

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)

description: We demonstrated that classical mechanics have, besides the well known quantum deformation, another deformation -- so called hyperbolic quantum mechanics. The classical Poisson bracket can be obtained as the limit $h\to 0$ not only of the ordinary Moyal bracket, but also hyperbolic analogue of the Moyal bracket. Thus there are two different deformations of classical phase-space: complex Hilbert space and hyperbolic Hilbert space (module over a so called hyperbolic algebra -- the two dimensional Clifford algebra). To prove the correspondence principle we use the calculus over the hyperbolic algebra similar to functional superanalysis of Vladimirov-Volovich. Ordinary (complex) and hyperbolic quantum mechanics are characterized by two types of interference perturbation of the classical formula of total probability: ordinary $\cos$-interference and hyperbolic $\cosh$-interference.

description: This article develops a mathematical model of Iron (Fe0) /sand filter taking into account the loss of porosity during the filtration process. The mass transport advection-dispersion equation is derived to predict, through numerical simulation, the spatiotemporal distribution of pollutants and the flow rate in the filter as well as the water quality at the exit of the filter. Simulation results demonstrated that by mixing sand and iron particles in proportion of 40 vol% Fe0, the filter can be used continuously for 83 months.

Our calculations reproduce these observations as the result of a steep metallicity gradient, within a single populations, induced by dissipative collapse of the gas component. We also predict strong [N/O] enhancements in the lowest metallicity stars in dwarf spheroidals, due to the preferential retention of ejected gas from intermediate mass stars, compared to Type II supernovae.

"Becoming More and More Panamanian": Contemporary Constructions of West Indian Identity in Urban Panama
Creators: name: Curtis, Ariana A.
Publisher: name: American University
Year: 2023

description: The rapid political, social, and economic changes in urban Panama during the last half century have differently affected Panamanians of West Indian heritage that grew up in Colón, Panama City, and the U.S. controlled Canal Zone. This study uses specific events to survey contemporary constructions of West Indian identity practice: the 1964 flag riots, the 1977 Torrijos-Carter Canal Treaties, the 1989 U.S. invasion, the 1999 American civilian and military withdrawal, and the 2010 Panamanian census. Together, these events structure my examination of relationships between identity construction and the state. This study explores the ways in which Black identity is constructed in distinct areas of the same nation, how and why those constructions change over time, and how those changes influence the current economic and political realities of Panamanians of West Indian heritage in the Republic of Panama. This dissertation uses ethnographic data and qualitative research methods to explore the discursive and cultural practices of West Indian identity in Panamanian urban spaces. Unlike other works about West Indians in Panama, I geographically unpack the assigned identity of "West Indian" and consider the ways in which location of origin complicates contemporary belonging and group identity. Panamanians of West Indian heritage lived both inside and outside of the U.S. controlled Canal Zone and on the Pacific and Atlantic coasts of the Republic of Panama, which created varying relationships with the American state via the U.S. controlled Canal Zone, the Panamanian state, and with each other. I conclude that Panamanians of West Indian heritage identify each other differently based on perceived differences in where and, consequently, how they grew up. These perceived differences shape social networks, organizational belonging, and group cohesion. Although Panama has two distinct groups of Black ethnicity, coloniales and West Indians, the absence of a divisive American territory and the influx of foreign immigration have moved African-descendent populations away from traditional ethnic divisions and toward a shared nation-based racial identity of Afro-Panameño.

Texture asymmetries as shear sense indicators in naturally deformed mono- and polyphase carbonate rocks

Publisher: name: FID GEO
Year: 1999

description: The microstructural and quantitative texture analyses of a naturally deformed calcite mylonite, a dolomite mylonite and a dolomitic calcite mylonite reveal different texture asymmetries for comparable deformation conditions. Calcite shows a c-axis maximum rotated against the shear sense with regard to the main shear plane. In contrast, the dolomite shows a c-axis maximum rotated with the shear sense. In accordance with the experimental and simulated textures from the literature, this difference proves e-twinning and r-slip for calcite and f-twinning and c-slip for dolomite as the main deformation mechanisms. The dolomitic calcite mylonite shows for both the calcite and the dolomite a c-axis maximum rotated against the shear sense. On account of the microstructure of this sample, the dolomite texture has been passively overtaken from the deformation texture of calcite during a late-deformative dolomitization. The results significantly contribute to the interpretation that the sampled shear zone is a transpressive strikeslip fault.

En primer lugar, para poder definir las capacidades institucionales se revisó la literatura, encontrando que su análisis es complejo porque quienes las han definido o medido, no han llegado a un consenso y, en general, se enfocan a aspectos ajenos a las instituciones. Es por ello que se propone un análisis centrado en el neo institucionalismo, a través del enfoque de la lógica institucional. Para su medición se compararon documentos orgánicos y programáticos desde dicho enfoque, encontrándose que la lógica institucional que persigue la organización es de corte estado centrista, mientras que en lo programático es mercantilista. Esta contradicción nos llevó a concluir que la contradicción en la lógica institucional del IMUVIG, provoca que este carezca de capacidad institucional para implementar la política de vivienda, aun poseyendo capacidades técnicas, políticas y administrativas suficientes.

Weathering behaviour and construction suitability of dimension stones from the Drei Gleichen area (Thuringia, Germany)

description: The construction suitability of a dimension stone depends on its weathering properties along with the petrology and the petrophysical properties. The aim of this study was to evaluate the suitability of the dimension stones from the “Drei Gleichen” area for construction and replacement purposes. In total, six sandstones (Ingersleben, Wachsenburg, Hindfelden, Seeberg, Röhnberg, Gleichenberg; Upper Triassic) as well as two carbonates (Wachsenburg sinter; Quaternary, Wandersleben dolomite; Middle Triassic) were analysed. The results from our laboratory and on-site studies of the dimension stones show that rocks from the same stratigraphic layer, like the sandstones from the upper Triassic, can show major differences in their petrophysical and weathering properties. These differences are attributed to their different diagenesis, resulting, e.g. in varying pore space, water balance and strength properties. The pore size distribution can be divided into four different groups based on their occurring maxima and micropore content. The determined water balance properties as well as moisture expansion and salt attack depend on these groups. Next to this, the mineralogical composition significantly influences the weathering resistance. Sandstones with a high content of altered lithoclasts show a high amount of moisture expansion, low strength and, in consequence, a low weathering resistance against salt attack. Based on the results of the present study, an evaluation of construction suitability could be accomplished. From the analysed sandstones, only the Seebergen sandstone is suitable for construction purposes due to its good availability, good strength properties (high compressive and tensile strength, low softening degree) as well as a low porosity. Furthermore, the Wachsenburg sandstone also shows good petrophysical and petrological properties, but exploitable deposits are too sparse to be of commercial interest. From the carbonates, the Wachsenburg sinter shows very suitable rock parameters, but only sparse outcrops occur, which are not appropriate for mining.

description: A joint experimental / theoretical investigation of the elastin-like octapeptide GVG(VPGVG) was carried out. In this paper a comprehensive molecular dynamics study of the temperature dependent folding and unfolding of the octapeptide is presented. The current study, as well as its experimental counterpart find that this peptide undergoes an "inverse temperature transition", ITT, leading to a folding at about 310-330 K. In addition, an unfolding transition is identified at unusually high temperatures approaching the boiling point of water. Due to the small size of the system two broad temperature regimes are found: the "ITT regime" (at about 280-320 K) and the "unfolding regime" at about T > 330 K, where the peptide has a maximum probability of being folded at approximately 330 K. A detailed molecular picture involving a thermodynamic order parameter, or reaction coordinate, for this process is presented along with a time-correlation function analysis of the hydrogen bond dynamics within the peptide as well as between the peptide and solvating water molecules. Correlation with experimental evidence and ramifications on the properties of elastin are discussed.

description: On The Way To The Peacock Room is a collection of poems and prose passages that investigates spirituality and sexuality. In it, I try to understand how my own desires have influenced my identity. And, my goal with this collection is simply to look at the meeting places, the interstitial spaces of human existence that I find most exhilarating, even when painful.

description: Very large volumes of spatial data increasingly become available and demand effective management. While there has been decades of research on spatial data management, few works consider the current state of commodity hardware, having relatively large memory and the ability of parallel multi-core processing. In this work, we re-consider the design of spatial indexing under this new reality. Specifically, we propose a main-memory indexing approach for objects with spatial extent, which is based on a classic regular space partitioning into disjoint tiles. The novelty of our index is that the contents of each tile are further partitioned into four classes. This second-level partitioning not only reduces the number of comparisons required to compute the results, but also avoids the generation and elimination of duplicate results, which is an inherent problem of spatial indexes based on disjoint space partitioning. The spatial partitions defined by our indexing scheme are totally independent, facilitating effortless parallel evaluation, as no synchronization or communication between the partitions is necessary. We show how our index can be used to efficiently process spatial range queries and drastically reduce the cost of the refinement step of the queries. In addition, we study the efficient processing of numerous range queries in batch and in parallel. Extensive experiments on real datasets confirm the efficiency of our approaches.

description: Supplementing palm kernel meal (PKM)-based diet with an exogenous enzyme can help to improve the utilization and minimize the negative consequences of the high fibre and antinutritional factors on performance and health of animals. Forty weaned male pigs with an average initial weight of 7.85 ± 0.31 kg were used to determine the effects of supplementing a PKM-based diet with enzyme inclusion, on blood parameters, carcass and organ charac?teristics. Pigs were allotted to four diets which include the control diet containing 55% PKM while the addition of 1, 2 and 3 g/kg enzyme cocktail was tested in a complete randomized design trial that lasted seven weeks. Feed and water were provided ad-lib and blood sampled via jugular vein after the trial. Pigs fed diets containing high PKM with or without enzyme, did not manifest any significant deviation in their haematology or serum variables. Enzyme inclusions reduce cholesterol concentrations (p<0.05), but no linear or quadratic effect of the enzyme was observed on alkaline phosphatase or creatinine concentration (p>0.05). Eviscerated weight increased (p<0.05) as enzyme inclusion increased but other carcass traits were not affected. Pancreas and empty stomach weights reduced quadratically with enzyme inclusion (p<0.05) and this may ostensibly be due to improved digestive activities of the organs. This study confirms that the inclusion of enzyme in diets containing high proportion of PKM does not have any nega?tive physiological effect on growing pig
Youth, Music, and Agency: Undoing Race, Poverty and Violence in Rio de Janeiro, Brazil

description: This work focuses on the intersection of youth, their music and their agency, all of which interact to shape identities and create social change in Rio de Janeiro, Brazil. Music as media activism serves as backdrop, narrative, response, and counterpoint rhythm to the interlocking systemic violence(s) affecting favela youth. Identity issues around race, poverty and violence are the central focus as Brazil's homicide rates are some of the highest in the world with much of it concentrated in Rio and perpetrated by the state against youth of color. In 1993 rampant violence reached a climax as poor black and brown youth were being murdered daily in Rio's streets. The city's image of paradise on earth, and Brazil's self-narrative of racial democracy were suffering. Musical genres of funk and hip-hop proliferated in Rio's favelas facilitating life stories told by youth of color. Lyrics of racism, chronic poverty and violence surfaced in resistance to imposed constructions of blackness, space, and worth. In dialogue and resistance, youth design alternative worldviews and identities while performing grassroots participatory citizenship. In these ways young people disrupt structural violence and re-work local and global identities.
Who works in the local European laboratories? a comparative study of networks in Euroregions

description: In Europe various policy areas have experienced transfers of authority to the supranational level of the European Union (EU) while subnational regions within countries have become more powerful under the principle of subsidiarity. The three traditional layers of European government are being transformed into a new form of network governance. The EU's multiple Euroregions that are funded by the INTERREG IMA program develop cross-border cooperation projects that are supposed to lead to policy network structures. The questions raised in my thesis explore how widespread these Euroregional networks are in practice, which organizations are included in the network and which actors are better linked than others. I conduct a comparative case study involving networks of two different Euroregions: The Euroregion Maas-Rhine (MRE), which embodies districts of Germany, Belgium and the Netherlands, and the Euroregion Pro Europa Viadrina, including Frankfurt/Oder and the region around the Polish city of Slubice. The empirical analysis consists of cataloguing all organizations that have established cross-border cooperation funded by INTERREG III A in the period 2000-2006. These organizations are grouped according to priority fields formulated by the respective Euroregion. It becomes clear that both Euroregions have established projects in multiple policy areas and that the amount of projects is very high. These projects are executed not only by local authorities or municipalities but several private organizations and societal actors cooperate. Therefore Euroregions can be seen as practical examples of network governance. Moreover, my findings reveal that the role of local authorities as system integrators is crucial. As the only actors which have partners in a large number of projects from different priority fields, they act as hubs connecting rather isolated subnetworks.

description: The world is composed of little things: beads of water in a hurricane, particles of dust before a drought. Nature's violence begins on such a small scale, all we can see is the aftermath -- the miniscule becoming magnificent. A Hard World for Little Things is a study of individual lenses and the intricate distortions that shape our lives. As the environment creates and destroys itself, we do the same, constantly, adjusting our views (of the world and ourselves) in search of a clear focus; one that will allow us to see the storms, the rainfall, and our hands as we catch each tiny drop.

description: Die vorliegende Arbeit untersucht mit Hilfe von fünf teilstandardisierten Leitfadeninterviews, wie in der Heilpädagogischen Früherziehung die Selbstwirksamkeit als bedeutender Resilienzfaktor gefördert wird. Das Interesse wird auf die Operationalisierung der Förderung auf der Handlungsebene des Kindes und in der Beratung und Begleitung der Eltern gerichtet.Die Sicht- und Handlungsweisen von Fachpersonen mit unterschiedlichen Erstausbildungen werden einander gegenübergestellt. Die Ergebnisse der qualitativen Inhaltsanalyse zeigen auf, dass die Selbstwirksamkeit in der Heilpädagogischen Früherziehung auf vielfältige Art und Weise gefördert werden kann. Die Beratung der Eltern stellt sich als herausfordernd dar. Die Handlungsweisen der verschiedenen Fachpersonen in der Praxis unterscheiden sich weniger, als die Theorien, auf die sie sich beziehen.
