description: Accumulated detailed knowledge about the neuronal activities in human brains has brought more attention to bio-inspired spiking neural networks (SNNs). In contrast to non-spiking deep neural networks (DNNs), SNNs can encode and transmit spatiotemporal information more efficiently by exploiting biologically realistic and low-power event-driven neuromorphic architectures. However, the supervised learning of SNNs still remains a challenge because the spike-timing-dependent plasticity (STDP) of connected spiking neurons is difficult to implement and interpret in existing backpropagation learning schemes. This paper proposes a fractional-order spike-timing-dependent gradient descent (FO-STDGD) learning model by considering a derived nonlinear activation function that describes the relationship between the quasi-instantaneous firing rate and the temporal membrane potentials of nonleaky integrate-and-fire neurons. The training strategy can be generalized to any fractional orders between 0 and 2 since the FO-STDGD incorporates the fractional gradient descent method into the calculation of spike-timing-dependent loss gradients. The proposed FO-STDGD model is tested on the MNIST and DVS128 Gesture datasets and its accuracy under different network structure and fractional orders is analyzed. It can be found that the classification accuracy increases as the fractional order increases, and specifically, the case of fractional order 1.9 improves by 155% relative to the case of fractional order 1 (traditional gradient descent). In addition, our scheme demonstrates the state-of-the-art computational efficacy for the same SNN structure and training epochs.

description: A deep neural network is a parametrization of a multilayer mapping of signals in terms of many alternatively arranged linear and nonlinear transformations. The linear transformations, which are generally used in the fully connected as well as convolutional layers, contain most of the variational parameters that are trained and stored. Compressing a deep neural network to reduce its number of variational parameters but not its prediction power is an important but challenging problem toward the establishment of an optimized scheme in training efficiently these parameters and in lowering the risk of overfitting. Here we show that this problem can be effectively solved by representing linear transformations with matrix product operators (MPOs), which is a tensor network originally proposed in physics to characterize the short-range entanglement in one-dimensional quantum states. We have tested this approach in five typical neural networks, including FC2, LeNet-5, VGG, ResNet, and DenseNet on two widely used data sets, namely, MNIST and CIFAR-10, and found that this MPO representation indeed sets up a faithful and efficient mapping between input and output signals, which can keep or even improve the prediction accuracy with a dramatically reduced number of parameters. Our method greatly simplifies the representations in deep learning, and opens a possible route toward establishing a framework of modern neural networks which might be simpler and cheaper, but more efficient.

On possible types of magnetospheres of hot Jupiters

description: We show that the orbits of exoplanets of the "hot Jupiter" type, as a rule, are located close to the Alfven point of the stellar wind of the parent star. At this, many hot Jupiters can be located in the sub-Alfven zone in which the magnetic pressure of the stellar wind exceeds its dynamic pressure. Therefore, magnetic field of the wind must play an extremely important role for the flow of the stellar wind around the atmospheres of the hot Jupiters. This factor must be considered both in theoretical models and in the interpretation of observational data. The analysis shows that many typical hot Jupiters should have shock-less intrinsic magnetospheres, which, apparently, do not have counterparts in the Solar System. Such magnetospheres are characterized, primarily, by the absence of the bow shock, while the magnetic barrier (ionopause) is formed by the induced currents in the upper layers of the ionosphere. We confirmed this inference by the three-dimensional numerical simulation of the flow of the parent star stellar wind around the hot Jupiter HD 209458b in which we took into account both proper magnetic field of the planet and magnetic field of the wind.

description: We study the thermodynamics and the susceptibilities of quark matter in the framework of two-flavor Nambu-Jona-Lasinio model at finite isospin chemical potential and temperature. Isospin number density, normalized energy density and trace anomaly are shown to be in good agreement with the available lattice data as well as with the results from chiral perturbation theory at zero temperature. We also study how susceptibilities depend on the isospin chemical potential and on temperature. We find a peak for the chiral, pion, and isospin susceptibilities at the critical isospin chemical potential, $μ_I^c(T)$, at the boundary of the phase transition between the normal and pion superfluid phase. Moreover, temperature makes the transition from normal to pion condended phase smoother. We also note that the pion susceptibility always remains zero in the normal phase while it is finite in the superfluid phase.

description: Feature selection technology is a key technology of data dimensionality reduction. Becauseof the lack of label information of collected data samples, unsupervised feature selection has attracted more attention. The universality and stability of many unsupervised feature selection algorithms are very low and greatly affected by the dataset structure. For this reason, many researchers have been keen to improve the stability of the algorithm. This paper attempts to preprocess the data set and use an interval method to approximate the data set, experimentally verifying the advantages and disadvantages of the new interval data set. This paper deals with these data sets from the global perspective and proposes a new algorithm-unsupervised feature selection algorithm based on neighborhood interval disturbance fusion(NIDF). This method can realize the joint learning of the final score of the feature and the approximate data interval. By comparing with the original unsupervised feature selection methods and several existing feature selection frameworks, the superiority of the proposed model is verified.

description: In this dissertation, we study etale correspondence of hyperbolic curves with unbounded dynamics. Mochizuki proved that over a field of characteristic 0, such curves are always Shimura curves. We explore variants of this question in positive characteristic, using graph theory, l-adic local systems, and Barsotti-Tate groups. Given a correspondence with unbounded dynamics, we construct an infinite graph with a large group of ”algebraic” automorphisms and roughly measures the ”generic dynamics” of the correspondence. We construct a specialization map to a graph representing the actual dynamics. Along the way, we formulate conjectures that etale correspondences with unbounded dynamics behave similarly to Hecke correspondences of Shimura curves. Using graph theory, we show that type (3,3) etale correspondences verify various parts of this philosophy. Key in the second half of this dissertation is a recent p-adic Langlands correspondence, due to Abe, which answers affirmatively the petites camarades conjecture of Deligne in the case of curves. This allows us the build a correspondence between rank 2 l-adic local systems with trivial determinant and Frobenius traces in Q and certain height 2, dimension 1 Barsotti-Tate groups. We formulate a conjecture on the fields of definitions of certain compatible systems of l-adic representations. Relatedly, we conjecture that the Barsotti-Tate groups over complete curves in positive characteristic may be ”algebraized” to abelian schemes.

description: We find and prove relationships between Riemann zeta values and central binomial sums. We also investigate alternating binomial sums (also called Apéry sums). The study of non-alternating sums leads to an investigation of different types of sums which we call multiple Clausen values. The study of alternating sums leads to a tower of experimental results involving polylogarithms in the golden ratio. In the non-alternating case, there is a strong connection to polylogarithms of the sixth root of unity, encountered in the 3-loop Feynman diagrams of {\tt hep-th/9803091} and subsequently in hep-ph/9910223, hep-ph/9910224, cond-mat/9911452 and hep-th/0004010.

description: Lambda-S is an extension to first-order lambda calculus unifying two approaches of non-cloning in quantum lambda-calculi. One is to forbid duplication of variables, while the other is to consider all lambda-terms as algebraic linear functions. The type system of Lambda-S has a constructor S such that a type A is considered as the base of a vector space while S(A) is its span. Lambda-S can also be seen as a language for the computational manipulation of vector spaces: The vector spaces axioms are given as a rewrite system, describing the computational steps to be performed. In this paper we give an abstract categorical semantics of Lambda-S* (a fragment of Lambda-S), showing that S can be interpreted as the composition of two functors in an adjunction relation between a Cartesian category and an additive symmetric monoidal category. The right adjoint is a forgetful functor U, which is hidden in the language, and plays a central role in the computational reasoning.

Publisher: name: Zenodo
Year: 2024

description: Background:

Objective: Determine the percentage of achievement of the therapeutic goal of blood pressure in pregnant patients with eclampsia.

Material and methods: A retrospective cohort of 32 pregnant patients with eclampsia admitted to the Intensive Care Unit (ICU) was studied. Their general data, ICU stay, mortality, and average blood pressure in the antepartum, intrapartum, and postpartum stages were documented. The percentage of cases in which the therapeutic goal of systolic (<160 mmHg) and diastolic (<110 mmHg) pressure was achieved in each stage and management with antihypertensive agents were calculated. The data were analyzed with descriptive statistics, Student's t test, Mann-Whitney U test, and chi square with the statistical program SPSS™ version 20.0. The value p <0.05 was significant.

Results: Maternal age 26.43±6.34 years, pregnancy 34.55±3.08 weeks, morbidities 21.87%, cesarean section in 96.87%, intrapartum complications 0%, reinterventions 0%, ICU stay 3.31 ± 2.41 days and mortality 3.12%. Achievement of the therapeutic goal: antepartum systolic blood pressure 37.5%, intrapartum 75% and postpartum 81.25%; diastolic blood pressure antepartum 68.75%, intrapartum 87.5% and postpartum 87.5%. Management: oral medications: three agents (methyldopa-hydralazine-metoprolol) 65.64%, two agents (methyldopa-hydralazine) 15.62%, single agent (methyldopa) 15.62%, and four agents (methyldopa-hydralazine-metoprolol-long acting nifedipine) 3.12%. Intravenous drugs: hydralazine boluses 12.5%, nimodipine infusion 6.25% and isosorbide dinitrate infusion 3.12%.

Conclusions: The percentage of achieving the therapeutic goal of antepartum, intrapartum and postpartum blood pressure in pregnant patients with eclampsia was acceptable.

This family contains the quasi-conformal manifolds and the topological manifolds modeled on germs of homeomorphisms of R^n possessing a derivative which is in L^p, with p > n(n+1)/2. We obtain an unbounded Fredholm module which defines a class in the K-homology of the manifold, the Chern character of which is the Hirzebruch polynomial in the Pontrjagin classes of the manifold. This generalizes previous works of N. Teleman for Lipschitz manifolds and of A. Connes, N. Teleman and D. Sullivan for quasi-conformal manifolds of even dimension.

description: Future lepton colliders such as the CEPC and FCC-ee would run as high-luminosity $Z-$boson factories, which offer a unique opportunity to study long-lived particles which couple to Z-bosons. In order to exemplify this particular advantage, in this work we consider one benchmark physics scenario where the long-lived lightest neutralinos pair $(\tildeχ_1^0\tildeχ_1^0)$ is produced from $Z-$decays in the context of the R-parity violating supersymmetry. Our analysis indicates that when assuming BR$(Z\rightarrow \tildeχ_1^0\tildeχ_1^0) = 10^{-3}$ and $m_{\tildeχ_1^0} \sim 40$ GeV, the model parameter $λ'_{112} / m^2_{\tilde{f}}$ can be discovered down to as low as $\sim 1.5 \times 10^{-14}$ ($3.9 \times 10^{-14}$) GeV$^{-2}$ at the FCC-ee (CEPC) with center-of-mass energy $\sqrt{s} = 91.2$ GeV and 150 (16) ab$^{-1}$ integrated luminosity. These limits exceed the projected sensitivity reaches of the ATLAS experiment at the HL-LHC and the proposed LHC experiments with far detectors (AL3X, CODEX-b, FASER, and MATHUSLA).

description: Dynamical studies of superbubbles and Wolf-Rayet ring nebulae show discrepancies from the standard, adiabatic model for wind-blown bubbles. We therefore study the physical properties and kinematics of three candidate bubbles blown by single O stars, to evaluate whether these discrepancies are also found in these simpler objects. Our sample candidates are N44F, N44J, and N44M, in the outskirts of the HII complex N44 in the Large Magellanic Cloud. We have obtained ground-based and HST emission-line images and high dispersion echelle spectra for these objects. From the Halpha luminosities and the [OIII]/Halpha ratios of these nebulae, we estimate the spectral types of the ionizing stars to be O7V, O9.5V and O9.5V for N44F, N44J, and N44M, respectively. We find that the observed expansion velocity of 12 km/s for N44F is consistent with the stellar wind luminosity expected from the central ionizing star, as predicted by the standard bubble model. The observed upper limits for the expansion velocities of N44J and N44M are also compatible with the expected values, within the uncertainties. We also report the discovery in N44F of strongly-defined dust columns, similar to those seen in the Eagle Nebula. The photoevaporation of these dense dust features may be kinematically important and may actually govern the evolution of the shell. The inclusion of photoevaporation processes may thus undermine the apparent agreement between the observed bubble dynamics and the simple adiabatic models.

description: A certain notion of canonical equivalence in quantum mechanics is proposed. It is used to relate quantal systems with discrete ones. Discrete systems canonically equivalent to the celebrated harmonic oscillator as well as the quartic and the quasi-exactly-solvable anharmonic oscillators are found. They can be viewed as a translation-covariant discretization of the (an)harmonic oscillator preserving isospectrality. The notion of the $q-$deformation of the canonical equivalence leading to a dilatation-covariant discretization preserving polynomiality of eigenfunctions is also presented.

Dynamics of the "Divestment-Investment" Process: An Investigation of the Process of Adaptation Occurring in the Ecological Transition of Leaving Home to Live at College
Creators: Lynch, Arthur A.
Publisher: name: Columbia University
Year: 1983
Subjects: subject: Social service

subject: FOS: Sociology

description: The overall focus of this study was to investigate the initial adaptation process to college. The adaptation process was viewed as embedded within the ecological transition of leaving home to live at college. The primary psychosocial tasks which provided the process criterion for adaptation were contained in the "divestment-investment" process. The study was divided into 2 phases which used a cross-sectional design. The major hypotheses of Phase I predicted a relationship between perceived adjustment and perceived family characteristics, as well as between perceived adjustment and separation feelings. For Phase II the hypotheses predicted a relationship between perceived adjustment and four adaptation criterion variables: information processing, autonomy, motivation, self-esteem.

The Ss for Phase I of the study consisted of 105 male freshmen from Columbia College and the School of Engineering. The Ss were administered the Bell Adjustment Inventory which determined perceived adjustment; the Family Adaptation and Cohesion Evaluation Scale which enabled assessment of perceived family cohesion and perceived family adaptation; a Separation scale which yielded scores on separation affect; and a demographic questionnaire which measured environmental variables.

In Phase II, adjustment scores derived from Phase I were compared with the four adaptation criterion variables. The four criterion variables for adaptation were determined by four judges using a content analysis of taped interviews with Ss from a subgroup (N = 30) of the sample population.

A multivariate analysis of variance, Eta and Oneway analyses were used to obtain results from the data of Phase I. A univariate analysis of variance, and Eta analysis were used to analyze Phase II data.

The major findings of Phase I were that relationships were found to exist between the Perceived Family Cohesion scores and the perceived adjustment scores, as well as between Perceived Family Cohesion scores and the Separation scores. The major findings of Phase II were that relationships were found to exist between the adaptation criterion variables of Motivation, Autonomy, and Self-esteem on the 3 Bell Adjustment groups for the two content areas of separation issues, and academic issues.

On the basis of the information which this exploratory study has provided, it seems reasonable to suggest that the individual's perceived level of family cohesion was instrumental in his initial adaptation to college.

description: RESUMO

Introdução: Nas últimas décadas, as diversas formas de tecnologia vêm crescendo gradativamente em nosso meio, o reconhecimento facial vem marcando uma revolução no campo da perícia criminal. Este progresso promissor, embora ofereça aprimoramentos substanciais na eficiência da prova pericial, também suscita importantes questionamentos éticos e legais. Objetivo: proporcionar uma análise sobre a tecnologia de reconhecimento facial e seu respaldo mediante a garantia dos direitos individuais. Método: Trata-se de uma pesquisa jurídica elaborada através de fontes de artigos, sites e órgãos federativos que tratam a temática de reconhecimento facial/da prova pericial e da garantia dos direitos individuais. Como critérios de inclusão, selecionamos de artigos, sites e órgãos federativos que tratam a temática de reconhecimento facial/da prova pericial e da garantia dos direitos individuais. Nos critérios de exclusão, retiramos trabalhos que tratavam a tecnologia artificial, porém não condizia com o reconhecimento facial; foram excluídos Leis, Decretos, Portarias de quaisquer instância e/ou projetos de lei que não tratava da temática. Foi realizado um levantamento em torno de 200 trabalhos e sites em periódicos, finalizando com 30 artigos dentre outros trabalhos para construção deste. Resultado: Para que o sistema de reconhecimento facial automatizado seja efetivo na prevenção delitiva e na instrução criminal, é necessário que esses bancos de dados sejam integrados entre as diversas forças de segurança das nações. Sem esse real compartilhamento de informações, a aplicabilidade da tecnologia ficaria restrita à criminalidade local. Em relação à privacidade, os direitos estão voltados à intimidade, o direito à honra, à imagem, a inviolabilidade do domicílio, o sigilo de correspondência e das comunicações telegráficas, de dados das comunicações telefônicas.

description: Multiple kernel methods less consider the intrinsic manifold structure of multiple kernel data and estimate the consensus kernel matrix with quadratic number of variables, which makes it vulnerable to the noise and outliers within multiple candidate kernels. This paper first presents the clustering method via kernelized local regression (CKLR). It captures the local structure of kernel data and employs kernel regression on the local region to predict the clustering results. Moreover, this paper further extends it to perform clustering via the multiple kernel local regression (CMKLR). We construct the kernel level local regression sparse coefficient matrix for each candidate kernel, which well characterizes the kernel level manifold structure. We then aggregate all the kernel level local regression coefficients via linear weights and generate the consensus sparse local regression coefficient, which largely reduces the number of candidate variables and becomes more robust against noises and outliers within multiple kernel data. Thus, the proposed method CMKLR avoids the above two limitations. It only contains one additional hyperparameter for tuning. Extensive experimental results show that the clustering performance of the proposed method on benchmark datasets is better than that of 10 state-of-the-art multiple kernel clustering methods.

description: Surgery, as developed by Browder, Kervaire, Milnor, Novikov, Sullivan, Wall and others is a method for comparing homotopy types of topological spaces with diffeomorphism or homeomorphism types of manifolds of dimension >= 5. In this paper, a modification of this theory is presented, where instead of fixing a homotopy type one considers a weaker information. Roughly speaking, one compares n-dimensional compact manifolds with topological spaces whose k-skeletons are fixed, where k is at least [n/2]. A particularly attractive example which illustrates the concept is given by complete intersections. By the Lefschetz hyperplane theorem, a complete intersection of complex dimension n has the same n-skeleton as CP^n and one can use the modified theory to obtain information about their diffeomorphism type although the homotopy classification is not known. The theory reduces this classification result to the determination of complete intersections in a certain bordism group. The restrictions are: If d = d_1 ... d_r is the total degree of a complete intersection X^n_{d_1,..., d_r} of complex dimension n, then the assumption is, that for all primes p with p(p-1) <= n+1, the total degree d is divisible by p^{[(2n+1)/(2p-1)]+1}. Theorem A. Two complete intersections X^n_{d_1,.,d_r} and X^n_{d'_1,\ldots , d'_s} of complex dimension n>2 fulfilling the assumption above for the total degree are diffeomorphic if and only if the total degrees, the Pontrjagin classes and the Euler characteristics agree.

description: Leonurus marrubiastrum ist eine hapaxanthe Art, die in der Regel zweijährig ist, unter günstigen Umständen ihren Lebenszyklus aber auch in einem Jahr vollenden kann. Unter natürlichen Bedingungen erreicht die Art leicht eine Wuchshöhe zwischen 1,2 m und 1,7 m. Die einsamigen Nüßchen können unter Wasser keimen und sich anschließend am Ufer etablieren. Die Art erweist sich im Experiment als nitrophil. Leonurus marrubiastrum zeigte in Mitteleuropa im vergangenen Jahrhundert einen starken Rückgang, insbesondere an Ruderalstandorten. Seit ca. 20 Jahren ist jedoch entlang der Elbe eine deutliche Zunahme der Populationsgrößen zu konstatieren. Ihren Schwerpunkt hat die Art in Deutschland derzeit in flussnahen Artemisietea-Gesellschaften, darüber hinaus an der Elbe auch im Chenopodion rubri und im Sisymbrion. Als relativ kurzlebige Art ist Leonurus marrubiastrum auf gestörte Flächen angewiesen: Vorkommen im Chenopodion rubri in Nähe der Uferspülsäume sowie in tiefer gelegenen Buhnenfeldern, im Bereich des Mittelwassers auf Buhnen und Uferwerken, vor allem aber an höher gelegenen Uferabbrüchen und sonstigen Störstellen im Senecionion fluviatilis, zugleich oft im Halbschatten von Bäumen. Im südöstlichen Mitteleuropa ist Leonurus marrubiastrum auch Bestandteil dörflicher Ruderalfluren des Arction. Insgesamt kann Leonurus marrubiastrum daher nur als Artemisietea-Kennart eingestuft werden.
description: Leonurus marrubiastrum is a hapaxanthous species, which normally is biennial. Under favorable circumstances it can however finish its life circle within one year. Under natural conditions the species reaches a height of 1.2 m to 1.7 m. The monospermous seeds are able to germinate under water, and the seedlings are able to establish an the river banks. The species is seen to be as nitrophilous in experiments. Leonurus marrubiastrum showed an enormous regression in Central Europe during the last century. For about 20 years however a clear increase is evident along the river Elbe. At the moment its centre in Germany is to be found in Artemisietea communities near rivers, at the Elbe also in communities of Chenopodion rubri and Sisymbrion. Because it is ephemeral, Leonurus marrubiastrum depends an disturbance: occurrence in Chenopdion rubri near the drift line, near middle high water at groynes, an higher river banks and other disturbed places within Agropyretalia, and especially in Senecionion fluviatilis. Leonurus marrubiastrum is nowadays still part of village ruderal communities of the alliance Arction. Therefore Leonurus marrubiastrum is classified by us as a character species of the class Artemisietea.

description: Restaurants in Chinatown have long been classified as part of its small businesses and studied in the sense of economic development of the neighborhood. In contrast, this paper studies the restaurant industry in Chinatown as a subject separated from other industries, emphasizing its uniqueness. It strives to explore the questions: How did Chinatown’s restaurant industry evolve through history? How did the interventions from stakeholders influence the restaurants? The study aims to find a way to help Chinatown’s restaurants survive against future difficulties.

Feynman-Kac formulas for Dirichlet-Pauli-Fierz operators with singular coefficients
Creators: name: Matte, Oliver

description: We derive Feynman-Kac formulas for Dirichlet realizations of Pauli-Fierz operators generating the dynamics of nonrelativistic quantum mechanical matter particles, which are minimally coupled to both classical and quantized radiation fields and confined to an arbitrary open subset of the Euclidean space. Thanks to a suitable interpretation of the involved Stratonovich integrals, we are able to retain familiar formulas for the Feynman-Kac integrands merely assuming local square-integrability of the classical vector potential and the coupling function in the quantized vector potential. Allowing for fairly general coupling functions becomes relevant when the matter-radiation system is confined to cavities with inward pointing boundary singularities.

description: Li2S is the final product of lithiation of sulfur cathodes in lithium-sulfur (Li-S) batteries. In this work, we study formation and diffusion of defects in Li2S. It is found that for a wide range of voltages (referenced to metal Li) between 0.17 V and 2.01 V, positively charged interstitial Li (Li+) is the most favorable defect type with a fixed formation energy of 1.02 eV. The formation energy of negatively charged Li vacancy (V−Li) is also constant, and it is only 0.13 eV higher than that of Li+. For a narrow range of voltages between 0.00 V and 0.17 V, the formation energy of neutral S vacancy is the lowest and it decreases with decreasing the cell voltage. The energy barrier for Li+ diffusion (0.45 eV), which takes place via an exchange mechanism, is 0.18 eV higher than that for V−Li (0.27 eV), which takes place via a single vacancy hopping. Considering formation energies and diffusion barriers, we find that ionic conductivity in Li2S is due to both Li+ and V−Li, but the latter mechanism being slightly more favorable.

description: In practical localization system design, researchers need to consider several aspects to make the positioning efficiently and effectively, e.g., the available auxiliary information, sensing devices, equipment deployment and the environment. Then, these practical concerns turn out to be the technical problems, e.g., the sequential position state propagation, the target-anchor geometry effect, the Non-line-of-sight (NLOS) identification and the related prior information. It is necessary to construct an efficient framework that can exploit multiple available information and guide the system design. In this paper, we propose a scalable method to analyze system performance based on the Cramér–Rao lower bound (CRLB), which can fuse all of the information adaptively. Firstly, we use an abstract function to represent all of the wireless localization system model. Then, the unknown vector of the CRLB consists of two parts: the first part is the estimated vector, and the second part is the auxiliary vector, which helps improve the estimation accuracy. Accordingly, the Fisher information matrix is divided into two parts: the state matrix and the auxiliary matrix. Unlike the theoretical analysis, our CRLB can be a practical fundamental limit to denote the system that fuses multiple information in the complicated environment, e.g., recursive Bayesian estimation based on the hidden Markov model, the map matching method and the NLOS identification and mitigation methods. Thus, the theoretical results are approaching the real case more. In addition, our method is more adaptable than other CRLBs when considering more unknown important factors. We use the proposed method to analyze the wireless sensor network-based indoor localization system. The influence of the hybrid LOS/NLOS channels, the building layout information and the relative height differences between the target and anchors are analyzed. It is demonstrated that our method exploits all of the available information for the indoor localization systems and serves as an indicator for practical system evaluation. View Full-Text
Dīn and Duniyā: Debating Sufism, Saint Shrines, and Money in the Lucknow Area

description: This dissertation asks how Muslims in north India today understand four paradoxical aspects of Sufi saint shrine traditions. The shrines of Sufi saints are sometimes regarded as apolitical, sacred, all-inclusive, and anti-elite religious spaces. At the same time, they are sites that are politicized, illegally bought and sold as commercial real estate, fuel for Islamic sectarian divisions, and often controlled by upper-caste Muslim elites. Based on the analysis of historical archival materials and twelve months of ethnographic fieldwork in Lucknow (Uttar Pradesh), this dissertation argues that shrines are sites that straddle the dīn-duniyā distinction in Islam. Dīn (understood as “religion” in the modern period) is the atemporal, immaterial domain of true spirituality, whereas duniyā (“world”) is the realm of this-worldly material concerns and temporal impermanence. As sites imbued with the ethereal barakah (love of God manifest as the power of a blessing) of Sufi saints that aid individuals in drawing near to God by transcending “worldly” desires and also material commodities that are aggressively competed over by adversarial stakeholders (e.g., the state, real estate mafias, sectarian rivals), these shrines are paradoxically both of dīn and of duniyā. When asked how one can differentiate between dīn and duniyā—for example, when a Sufi politician is acting a religious manner or in a worldly manner—many of my interviewees explained that one can distinguish between these two domains based on the material presence of money. In this dissertation, I argue that the concept of money (paisā; also, “money” in English) acts as a symbol to help Muslims in Lucknow navigate this paradoxical quality. By attributing to the materiality of money those aspect of shrine operations associated with duniyā, interviewees effectively identified the boundary line dividing dīn from duniyā, thereby resolving the ostensibly contradictory nature of, for example, the politicization of an apolitical space. As a key signifier in the broader neoliberal context of Lucknow and the global politics of Sufism, money is an important concept by which Muslims make sense of the social, economic, and political complexities of Muslim life in the north India.

description: This paper gives an overview over Meshfree Methods. Starting point is an extended and modified classification of Meshfree Methods due to three aspects: The construction of a partition of unity, the choice of an approximation either with or without using an extrinsic basis and the choice of test functions, resulting into a collocation, Bubnov-Galerkin or Petrov-Galerkin Meshfree Method. Most of the relevant Meshfree Methods are described taking into account their different origins and viewpoints as well as their advantages and disadvantages. Typical problems arising in meshfree methods like integration, treatment of essential boundary conditions, coupling with mesh-based methods etc.~are discussed. Some valuing comments about the most important aspects can be found at the end of each section. This text was revised in 2004

description: Given the tremendous energy challenges Morocco faces, and its potential role as an exporter of green electricity to Europe, the country has been particularly targeted by Germany’s efforts to promote the uptake of renewable energies abroad. This paper explores whether ideas and policies in the field of renewable energy effectively traveled through transfer channels established between Germany and Morocco. In particular, the question of how Morocco’s policy objectives shaped the result of transfer processes is discussed, shedding light on a currently under-researched determinant for policy transfer. Drawing upon forty-five semi-structured interviews with Moroccan, German, and international stakeholders, as well as card-ranking exercises, the article provides first-hand insights into the dynamics and drivers of Morocco’s “energy transition”. Findings presented in the article show that differing policy objectives did not preclude the transfer of ideas between Germany and Morocco, but shaped its outcome with regard to policy instrument selection. While basic policy orientations in favour of renewable energies were facilitated by transferred knowledge, a perceived incompatibility between domestic policy objectives and the policy instruments used in the foreign model led to selective lesson-drawing from the German example. This finding underlines the importance for “senders” who wish to actively promote sustainable energy policies abroad to adapt outreach strategies to the policy objectives of potential followers.
