description: Abstract: "During the summer of 1994, as part of the Careers in Science and Applied Technology (CAST) program, seven high school students and an elementary school teacher worked together to document the current pollution patterns on the Cathedral of Learning on the University of Pittsburgh campus. This report presents the results of their research in which they used surveying, sketching and photography to document the pollution patterns. They also recorded their data in an AutoCAD model of the Cathedral. This project was part of a larger study being done for the National Park Service on Acid Deposition on Limestone Buildings. The project was also sponsored by the Engineering Design Research Center under the Green Design initiative."

description: Com esta bibliografia, pretendemos contribuir para um melhor entendimento do movimento sócio-religioso conhecido por Reforma, e especialmente, as suas repercussões, directas e indirectas, no nosso país. Os protestantes só tardiamente e com muitas dificuldades é que puderam entrar e radicarem-se em Portugal. Em relação a praticamente toda a Lusofonia, será a Igreja Reformada Holandesa a primeira a surgir em Portugal (1641). Hoje, representam 2,5-3% da população portuguesa em todas as denominações protestantes, evangélicas e algumasmenos ortodoxas. Não quisemos deixar de fora os novos países da Língua Oficial Portuguesa, em virtude da sua relação histórica, e para podermos estabelecer essa ponte com o Protestantismo, consideramo-los no período colonial até à sua independência. Assim sendo, esperamos que esta seja uma primeira ajuda, útil para todos os que desejem investigar o Protestantismo Lusófono.

description: Block tridiagonal matrices arise in applied mathematics, physics, and signal processing. Many applications require knowledge of eigenvalues and eigenvectors of block tridiagonal matrices, which can be prohibitively expensive for large matrix sizes. In this paper, we address the problem of the eigendecomposition of block tridiagonal matrices by studying a connection between their eigenvalues and zeros of appropriate matrix polynomials. We use this connection with matrix polynomials to derive a closed-form expression for the eigenvectors of block tridiagonal matrices, which eliminates the need for their direct calculation and can lead to a faster calculation of eigenvalues. We also demonstrate with an example that our work can lead to fast algorithms for the eigenvector expansion for block tridiagonal matrices.

description: A cronologia que se apresenta neste artigo, permite colocar em ordem os principais acontecimentos que, directa ou indirectamente, marcaram a história do Protestantismo lusófono. Apesar de Portugal não ter tido o privilégio de conhecer a Reforma, e do tardio interessedos portugueses pelo Protestantismo, este acabou por efectivamente chegar até nós com vitalidade e expressão, a partir dos princípios do século XIV, ultrapassando impedimentos legais e ilegais, lutas e perseguições levantadas, quer pela Igreja católica quer pelas monarquias e ditaduras. É nosso desejo que, no futuro, esta cronologia possa ser aumentada e melhorada, através do contributo de mais investigadores que trabalhem na recuperação da história do Protestantismo português e do Protestantismo lusófono.

description: We describe a quasiperiodic optical lattice, created by a physical realization of the abstract cut-and-project construction underlying all quasicrystals. The resulting potential is a generalization of the Fibonacci tiling. Calculation of the energies and wavefunctions of ultracold atoms loaded into such a lattice demonstrate a multifractal energy spectrum, a singular continuous momentum-space structure, and the existence of controllable edge states. These results open the door to cold atom quantum simulation experiments in tunable or dynamic quasicrystalline potentials, including topological pumping of edge states and phasonic spectroscopy.

description: In this Letter we investigate Quantum Darwinism and the emergence of a classical world from the quantum one in connection with the spectral properties of the environment. We use a microscopic model of quantum environment in which, by changing a simple system parameter, we can modify the information back flow from environment into the system, and therefore its non-Markovian character. We show that the presence of memory effects hinders the emergence of classical objective reality. We conjecture that this phenomenon is connected to the absence of a measurement-scheme interpretation for quantum trajectories in the non-Markovian regime.

description: We consider the the van der Waals force involving excited atoms in general environments, constituted by magnetodielectric bodies. We develop a dynamical approach studying the dynamics of the atoms and the field, mutually coupled. When only one atom is excited, our dynamical theory suggests that for large distances the van der Waals force acting on the ground-state atom is monotonic, while the force acting in the excited atom is spatially oscillating. We show how this latter force can be related to the known oscillating Casimir--Polder force on an excited atom near a (ground-state) body. Our force also reveals a population-induced dynamics: for times much larger that the atomic lifetime the atoms will decay to their ground-states leading to the van der Waals interaction between ground-state atoms.

description: The trend in the electric power system is to move towards increased amounts of distributed resources which suggests a transition from the current highly centralized to a more distributed control structure. In this paper, we propose a method which enables a fully distributed solution of the DC Optimal Power Flow problem (DC-OPF), i.e. the generation settings which minimize cost while supplying the load and ensuring that all line flows are below their limits are determined in a distributed fashion. The approach consists of a distributed procedure that aims at solving the first order optimality conditions in which individual bus optimization variables are iteratively updated through simple local computations and information is exchanged with neighboring entities. In particular, the update for a specific bus consists of a term which takes into account the coupling between the neighboring Lagrange multiplier variables and a local innovation term that enforces the demand/supply balance. The buses exchange information on the current update of their multipliers and the bus angle with their neighboring buses. An analytical proof is given that the proposed method converges to the optimal solution of the DC-OPF. Also, the performance is evaluated using the IEEE Reliability Test System as a test case

Da crítica à sociologia da religião uma viragem e seu impacto sócio-cultural*
Creators: name: Dix, Steffen
Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: A sociologia da religião é ainda uma disciplina relativamente jovem dentro da realidade académica. Tendo em conta as dificuldades recentes em reagir aos movimentos na paisagem religiosa actual pode parecer que este ramo da sociologia já se encontra numa crise profunda. Uma possibilidade de redefinir o lugar da sociologia da religião encontra-se também na reflexão sobre as origens desta disciplina científica que nasceu dentro do seio da crítica da religião. E esta remonta curiosamente das primeiras perguntas inocentes sobre a origem do mundo fora de uma explicação divina. O artigo presente pretende redesenhar em traços gerais o desenvolvimento da crítica da religião a partir dos filósofos pré-socraticos até os escritos de Feuerbach e chama depois brevemente atenção para Karl Marx, Friedrich Nietzsche e Sigmund Freud cujos criticas da religião tiveram um impacto enorme para a futura sociologia da religião.

description: The use of Digital Object Identifiers (DOI) for scientific data and scientific software is increasingly common practice in many disciplines, including in Geodesy. Today, DOI-referenced datasets are fully citable in scholarly literature and more and more journals require the public availability of data underlying scientific results and their citation in research articles. Technical implementations, like Scholix (a framework for Scholarly Link Exchange) enable direct links between literature and data and support the visibility of research data. Key elements for enabling these links and for interconnecting publications with data, code, persons, institutions, etc., and are resolvable persistent identifier (PID), that should be included in the DOI metadata. Geodetic services of the International Association for Geodesy (IAG) are international key player for geodetic data provision and distribution. Their operating institutions and funding agencies increasingly require the provision of tangible data use and access statistics. Credit through citation was a major reason for the IAG’s Global Geodetic Observing System (GGOS) to establish a Working Group on using DOI for geodetic data sets (GGOS DOI WG) and for the working group members. The GGOS DOI WG was established in 2019 and includes international representatives of IAG Services and geodetic data centres as well as associated members that aims at developing best practices and recommendations for the consistent implementation of DOIs across all IAG Services and in the greater geodetic community. This presentation will give an update on recent group activities and on the status of DOI minting for geodetic datasets across IAG Services.

description: We propose a sampling theory for signals that are supported on either directed or undirected graphs. The theory follows the same paradigm as classical sampling theory. We show that the perfect recovery is possible for graph signals bandlimited under the graph Fourier transform, and the sampled signal coefficients form a new graph signal, whose corresponding graph structure is constructed from the original graph structure, preserving frequency contents. By imposing a specific structure on the graph, graph signals reduce to finite discrete-time signals and the proposed sampling theory works reduces to classical signal processing. We further establish the connection to frames with maximal robustness to erasures as well as compressed sensing, and show how to choose the optimal sampling operator, how random sampling works on circulant graphs and Erdos-R ˝ enyi graphs, ´ and how to handle full-band graph signals by using graph filter banks. We validate the proposed sampling theory on the simulated datasets of Erdos-R ˝ enyi graphs and small-world graphs, and a ´ real-world dataset of online blogs. We show that for each case, the proposed sampling theory achieves perfect recovery with high probability. Finally, we apply the proposed sampling theory to semi-supervised classification of online blogs and digit images, where we achieve similar or better performance with fewer labeled samples compared to the previous work.

description: E-mail has become indispensable in today’s networked society. However, the huge and ever-growing volume of spam has become a serious threat to this important communication medium. It not only affects e-mail recipients, but also causes a significant overload to mail servers which handle the e-mail transmission.

We perform an extensive analysis of IP addresses and IP aggregates given by network-aware clusters in order to investigate properties that can distinguish the bulk of the legitimate mail and spam. Our analysis indicates that the bulk of the legitimate mail comes from long-lived IP addresses. We also find that the bulk of the spam comes from network clusters that are relatively long-lived. Our analysis suggests that network-aware clusters may provide a good aggregation scheme for exploiting the history and structure of IP addresses.

We then consider the implications of this analysis for prioritizing legitimate mail. We focus on the situation when mail server is overloaded, and the goal is to maximize the legitimate mail that it accepts. We demonstrate that the history and the structure of the IP addresses can reduce the adverse impact of mail server overload, by increasing the number of legitimate e-mails accepted by a factor of 3.

description: In the hole-doped cuprates, a small amount of carriers suppresses antiferromagnetism and induces superconductivity. In the electron-doped cuprates, on the other hand, superconductivity appears only in a narrow range of high electron concentration ($\sim$ doped Ce content) after reduction annealing, and strong antiferromagnetic (AFM) correlation persists in the superconducting phase. Recently, Pr$_{1.3-x}$La$_{0.7}$Ce$_{x}$CuO$_{4}$ (PLCCO) bulk single crystals annealed by a "protect annealing" method showed a high $T_c$ of $\sim$ 27 K for small Ce content down to $x \sim 0.05$. By angle-resolved photoemission spectroscopy (ARPES) measurements of PLCCO crystals, we observed a sharp quasi-particle peak on the entire Fermi surface without signature of an AFM pseudogap unlike all the previous work, indicating a dramatic reduction of AFM correlation length and/or of magnetic moments. The superconducting state was found to extend over a wide electron concentration range. The present ARPES results fundamentally change the long-standing picture on the electronic structure in the electron-doped regime.

description: We study distributed optimization problems when N nodes minimize the sum of their individual costs subject to a common vector variable. The costs are convex, have Lipschitz continuous gradient (with constant L), and bounded gradient. We propose two fast distributed gradient algorithms based on the centralized Nesterov gradient algorithm and establish their convergence rates in terms of the per-node communications K and the per-node gradient evaluations k. Our first method, Distributed NesterovGradient, achieves rates O( logK/K) and O(logk/k). Our second method, Distributed Nesterov gradientwith Consensus iterations, assumes at all nodes knowledge of L and μ(W) - the second largest singular value of the N ×N doubly stochastic weight matrix W. It achieves rates O( 1/ K2-ξ) and O( 1/k2) ( ξ > 0 arbitrarily small). Further, we give for both methods explicit dependence of the convergence constants on N and W. Simulation examples illustrate our findings.

description: Fast Fourier transform algorithms on large data sets achieve poor performance on various platforms because of the inefficient strided memory access patterns. These inefficient access patterns need to be reshaped to achieve high performance implementations. In this paper we formally restructure 1D, 2D and 3D FFTs targeting a generic machine model with a two-level memory hierarchy requiring block data transfers, and derive memory access pattern efficient algorithms using custom block data layouts. Using the Kronecker product formalism, we integrate our optimizations into Spiral framework. In our evaluations we demonstrate that Spiral generated hardware designs achieve close to theoretical peak performance of the targeted platform and offer significant speed-up (up to 6.5x) compared to naive baseline algorithms.

description: Intraband and interband contributions to the current-driven spin-orbit torque in magnetic materials lacking inversion symmetry are theoretically studied using Kubo formula. In addition to the current-driven field-like torque ${\bf T}_{\rm FL}= τ_{\rm FL}{\bf m}\times{\bf u}_{\rm so}$ (${\bf u}_{\rm so}$ being a unit vector determined by the symmetry of the spin-orbit coupling), we explore the intrinsic contribution arising from impurity-independent interband transitions and producing an anti-damping-like torque of the form ${\bf T}_{\rm DL}= τ_{\rm DL}{\bf m}\times({\bf u}_{\rm so}\times{\bf m})$. Analytical expressions are obtained in the model case of a magnetic Rashba two-dimensional electron gas, while numerical calculations have been performed on a dilute magnetic semiconductor (Ga,Mn)As modeled by the Kohn-Luttinger Hamiltonian exchanged coupled to the Mn moments. Parametric dependences of the different torque components and similarities to the analytical results of the Rashba two-dimensional electron gas in the weak disorder limit are described.

description: In this paper we provide rigorous proof for the convergence of an iterative voting-based image segmentation algorithm called Active Masks. Active Masks (AM) was proposed to solve the challenging task of delineating punctate patterns of cells from fluorescence microscope images. Each iteration of AM consists of a linear convolution composed with a nonlinear thresholding; what makes this process special in our case is the presence of additive terms whose role is to "skew" the voting when prior information is available. In real-world implementation, the AM algorithm always converges to a fixed point. We study the behavior of AM rigorously and present a proof of this convergence. The key idea is to formulate AM as a generalized (parallel) majority cellular automaton, adapting proof techniques from discrete dynamical systems.

description: ABSTRACT Background: Dental implant placement has evolved over time with the introduction of numerous novel protocols. Following tooth extraction throughout the healing phase, alveolar ridge resorption is a potential issue that can be mitigated by the utilisation of a variety of techniques, one of which is the placement of immediate implants. The immediate implant treatment protocol offers numerous benefits, such as minimal surgical procedures, which thereby reduce overall treatment time, preserve bone height, and produce better aesthetic results, particularly in the anterior region. Such protocols have made implant insertion so much easier that results can now be anticipated more precisely. The distance between the lateral surface of an implant and surrounding alveolus is known as the jumping gap distance (JGD). JGD of >1.5 mm affects spontaneous bone healing. Research incorporating biomaterials such as membranes produced from blood and bone grafts has significantly contributed to the success of this therapy. Hence, an intent of this study is to evaluate the efficiency of combination of A-PRF in with DFDBA placed simultaneously into an extraction socket followed by placement of immediate implant on the clinical and radiological outcomes. Methodology: This research will be carried out over the course of a year. Twelve implants will be placed in systemically healthy individuals with one tooth/teeth in the maxilla and/or mandible indicated for extraction. Using a two-stage protocol, implant placement will be done simultaneously after extraction along with augmentation with A-PRF and DFDBA. The second stage surgery will be conducted three months after implant placement. Within 3-6 weeks, abutments will be connected and the final prosthesis will be placed. Expected results: Crestal bone changes and implant stability after using of A-PRF and DFDBA will serve as indicators to determine the implant's success after 6 months. Conclusion: The augmentation procedures have shown to be successful in obtaining bone fill and in resolving bone defects that are present in proximity with implants. An immediate implant placement along with bone augmentation may decrease resorption of horizontal bone.

description: In a fully-gapped superconductor the electronic Raman response has a pair-breaking peak at twice the superconducting gap $Δ$, if the Bogoliubov excitations are uncorrelated. Motivated by the iron based superconductors, we study how this peak is modified if the superconducting phase hosts a nematic-structural quantum critical point. We show that, upon approaching this point by tuning, e.g., doping, the growth of nematic correlations between the quasiparticles transforms the pair-breaking peak into a nematic resonance. The mode energy is below 2$Δ$, and stays finite at the quantum critical point, where its spectral weight is sharply enhanced. The latter is consistent with recent experiments on electron-doped iron based superconductors and provides direct evidence of nematic correlations in their superconducting phases.

description: We compare the outcomes of the most prominent strategy-proof and stable algorithm (Deferred Acceptance, DA) and the most prominent strategy-proof and Pareto optimal algorithm (Top Trading Cycles, TTC) to the allocation generated by the rank-minimizing mechanism (RM). While one would expect that RM improves upon both DA and TTC in terms of rank efficiency, the size of the improvement is nonetheless surprising. Moreover, while it is not explicitly designed to do so, RM also significantly improves the placement of the worst-off student. Furthermore, RM generates less justified envy than TTC. We corroborate our findings using data on school admissions in Budapest.

description: Spyware is a class of malicious code that is surreptitiously
installed on victims’ machines. Once active,
it silently monitors the behavior of users, records their
web surfing habits, and steals their passwords. Current
anti-spyware tools operate in a way similar to traditional
virus scanners. That is, they check unknown programs
against signatures associated with known spyware instances.
Unfortunately, these techniques cannot identify
novel spyware, require frequent updates to signature
databases, and are easy to evade by code obfuscation.

In this paper, we present a novel dynamic analysis approach
that precisely tracks the flow of sensitive information
as it is processed by the web browser and any loaded
browser helper objects. Using the results of our analysis,
we can identify unknown components as spyware and
provide comprehensive reports on their behavior. The
techniques presented in this paper address limitations of
our previouswork on spyware detection and significantly
improve the quality and richness of our analysis. In particular,
our approach allows a human analyst to observe
the actual flows of sensitive data in the system. Based
on this information, it is possible to precisely determine
which sensitive data is accessed and where this data is
sent to. To demonstrate the effectiveness of the detection
and the comprehensiveness of the generated reports, we
evaluated our system on a substantial body of spyware
and benign samples.

description: Because of its nearness to Earth, the centre of the Milky Way is the only galaxy nucleus in which we can study the characteristics, distribution, kinematics, and dynamics of the stars on milli-parsec scales. We have accurate and precise measurements of the Galactic centre's central black hole, Sagittarius A*, and can study its interaction with the surrounding nuclear star cluster in detail. This contribution aims at providing a concise overview of our current knowledge about the Milky Way's central black hole and nuclear star cluster, at highlighting the observational challenges and limitations, and at discussing some of the current key areas of investigation.

title: Role of cell-surface receptor LRP1 in the development of lung fibrosis

description: Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease leading to a reduction of lung function, respiratory failure, and death. Around 3 million people are affected by IPF with a median survival after diagnosis of approximately 3 years. Currently there are no effective treatments available partly due to the incomplete understanding of molecular mechanisms that drive fibrosis through excessive accumulation of collagens, the hallmark of IPF. Low-density lipoprotein receptor-related protein 1 (LRP1) is a ubiquitously expressed cell-surface receptor that is involved in many physiological roles. LRP1 mediates clathrin-dependent endocytosis of various molecules (LRP1 ligands) and modulates cellular signalling pathways. The relevance of LRP1 gene to lung function was discovered by a large genome-wide association study. However, little is known about its role in lung health and disease in vitro. In this study, the role of LRP1 in lung tissue in vivo was investigated using conditional Lrp1 knockout (KO) mice models. Since lung tissue consists of a variety of cell types, I first deleted Lrp1 in the whole body. Global deletion of Lrp1 gene in adulthood caused a rapid weight loss (>20%) and gastro-intestinal abnormalities, suggesting a crucial role of LRP1 in the digestion system and difficulty to use this mouse model to investigate the respiratory system. Among various lung cells, fibroblasts play a major role in collagen deposition. I thus specifically deleted Lrp1 in lung fibroblasts and challenged the mice with bleomycin to induce lung fibrosis. I discovered that excess collagen deposition was observed in control mice, whereas almost no collagen accumulation was detected in fibroblast-selective Lrp1 knockout mice. I also found that the inhibition of LRP1-mediated endocytosis induces cell death of various types of cells in vitro, highlighting the cytotoxicity of prolonged presence of LRP1 ligands. Finally, I identified molecules regulated by LRP1 in lung tissue by proteomics analysis. These findings shed light on novel in vivo roles of LRP1 that play a major role in the digestive system. Moreover, fibroblast LRP1 plays a crucial role in excess collagen deposition during the development of lung fibrosis. Identifying molecular mechanisms behind LRP1 function in collagen deposition may uncover new therapeutic approaches for lung fibrosis disease.

description: Solar prominences are clouds of cool plasma levitating above the solar surface and insulated from the million-degree corona by magnetic fields. They form in regions of complex magnetic topology, characterized by non-potential fields, which can evolve abruptly, disintegrating the prominence and ejecting magnetized material into the heliosphere. However, their physics is not yet fully understood because mapping such complex magnetic configurations and their evolution is extremely challenging, and must often be guessed by proxy from photometric observations.Using state-of-the-art spectro-polarimetric data, we reconstruct the structure of the magnetic field in a prominence. We find that prominence feet harbor helical magnetic fields connecting the prominence to the solar surface below.

description: The thin, extended planes of satellite galaxies detected around both the Milky Way and Andromeda are not a natural prediction of the LCDM paradigm. Galaxies in these distinct planes may have formed and evolved in a different way (e.g., tidally) to their off-plane neighbours. If this were the case, one would expect the on- and off-plane dwarf galaxies in Andromeda to have experienced different evolutionary histories, which should be reflected by the chemistries, dynamics, and star formation histories of the two populations. In this work, we present new, robust kinematic observations for 2 on-plane M31 dSphs (And XVI and XVII) and compile and compare all available observational metrics for the on- and off-plane dwarfs to search for a signal that would corroborate such a hypothesis. We find that, barring their spatial alignment, the on- and off-plane Andromeda dwarf galaxies are indistinguishable from one another, arguing against vastly different formative and evolutionary histories for these two populations.

description: Gravitational analyzes in lower dimensions has become a field of active research interest ever since Banados, Teitelboim and Zanelli (BTZ) (Phys. Rev. Lett. 69, 1849, 1992) proved the existence of a black hole solution in (2 + 1) dimensions. The BTZ metric has inspired many investigators to develop and analyze circularly symmetric stellar models which can be matched to the exterior BTZ metric. We have obtained two new classes of solutions for a (2 + 1)-dimensional anisotropic star in anti-de Sitter background space-time which have been obtained by assuming that the equation of state (EOS) describing the material composition of the star could either be linear or non-linear in nature. By matching the interior solution to the BTZ exterior metric with zero spin, we have demonstrated that the solutions provided here are regular and well-behaved at the stellar interior.

description: In this paper, we examine several algorithms suitable for the hardware implementation of the discrete Fourier transform (DFT) with non-power-of two problem size. We incorporate these algorithms into Spiral, a tool capable of automatically generating corresponding hardware implementations. We discuss how each algorithm can be used to generate different types of hardware structures, and we demonstrate that our tool is able to produce hardware implementations of non-power-of-two sized DFTs over a wide range of cost/performance tradeoff points.

description: Anhoraeomorphus longicollis (Franz), comb. n.
 Horaeomorphus longicollis Franz, 1986b: 157.
 Remarks. The holotype (the only known specimen) is deposited in Muséum National d’Histoire Naturelle, Paris and was not available for my study. Characters described and illustrated by Franz include the aedeagus with a pair of elongate distolateral endophallic sclerites accompanied by median proximal assemblage of asymmetrical structures, and male metatibiae broadened in distal third, which are typical of Anhoraeomorphus. According to Franz (1986b), A. longicollis is most similar to A. diegoi. Judging from the aedeagus of A. longicollis illustrated in Franz (1986b): fig. 141), and that of A. diegoi studied here, these two names may be synonyms. Re-mounting and examination of the aedeagus of the holotype of A. longicollis is necessary to verify this view, but currently the Muséum National d'Histoire Naturelle does not issue loans of type specimens.
 Distribution. Northern Madagascar (Analanjirofo Region).

description: The CFHTLS presents a unique data set for weak lensing studies, having high quality imaging and deep multi-band photometry. We have initiated an XMM-CFHTLS project to provide X-ray observations of the brightest X-ray selected clusters within the wide CFHTLS area. Performance of these observations and the high quality of CFHTLS data, allows us to revisit the identification of X-ray sources, introducing automated reproducible algorithms, based on the multi-color red sequence finder. We have also introduced a new optical mass proxy. We provide the calibration of the red sequence observed in the CFHT filters and compare the results with the traditional single color red sequence and photoz. We test the identification algorithm on the subset of highly significant XMM clusters and identify 100% of the sample. We find that the integrated z-band luminosity of the red sequence galaxies correlates well with the X-ray luminosity with a surprisingly small scatter of 0.20 dex. We further use the multi-color red sequence to reduce spurious detections in the full XMM and RASS data sets, resulting in catalogs of 196 and 32 clusters, respectively. We made spectroscopic follow-up observations of some of these systems with HECTOSPEC and in combination with BOSS DR9 data. We also describe the modifications needed to the source detection algorithm in order to keep high purity of extended sources in the shallow X-ray data. We also present the scaling relation between X-ray luminosity and velocity dispersion.

description: We study a chain of four interacting rotors (rotators) connected at both ends to stochastic heat baths at different temperatures. We show that for non-degenerate interaction potentials the system relaxes, at a stretched exponential rate, to a non-equilibrium steady state (NESS). Rotors with high energy tend to decouple from their neighbors due to fast oscillation of the forces. Because of this, the energy of the central two rotors, which interact with the heat baths only through the external rotors, can take a very long time to dissipate. By appropriately averaging the oscillatory forces, we estimate the dissipation rate and construct a Lyapunov function. Compared to the chain of length three (considered previously by C. Poquet and the current authors), the new difficulty with four rotors is the appearance of resonances when both central rotors are fast. We deal with these resonances using the rapid thermalization of the two external rotors.
