description: This paper is intended to consider, in the light of the recent transformation of the Israeli kibbutz, the variety of social experiments which similarly illustrate the Proudhonian-Comtian-Durkheimian emphases on cooperation and collective solidarity, within societies dominated by market economy, the philosophy of progress and, nowadays especially, processes of globalization. These forms draw their interest from the fact that they put this vision to empirical test which shows the tensions, difficulties, and potentialities involved. We will especially focus on the kibbutz, the Mondragon complex of cooperatives and the American communes which show, beyond the differences of context and the singularity of each specific type, how far collectivism may concur with individualism, and solidarity and egalitarianism with social differentiation and conflict. On the other hand, the comparative analysis also reveals, in varying respects and at diverse degrees, similar concerns, dilemmas and tensions. As a rule, the tension between the enterprise and the community principles has gradually witnessed a predominance of the former over the latter and this "embourgeoisement" leads to confrontations between values and aspirations as well as between callings and interests. The collective's survival, it appears, is endangered both when it is threatened by insolvency - ipso Jacto - and when it is successful - as it risks then to be torn apart by divergent interests which impend on its moral purposes. Above all, this comparative analysis breaks the naivety of those who fully participate to this era of globalization and still perceive utopia beyond technocracy.

description: We present a detailed study of the geometry, structure and energetics of carbon nanotube caps. We show that the structure of a cap uniquely determines the chirality of the nanotube that can be attached to it. The structure of the cap is specified in a geometrical way by defining the position of six pentagons on a hexagonal lattice. Moving one (or more) pentagons systematically creates caps for other nanotube chiralities. For the example of the (10,0) tube we study the formation energy of different nanotube caps using ab-initio calculations. The caps with isolated pentagons have an average formation energy 0.29+/-0.01eV/atom. A pair of adjacent pentagons requires a much larger formation energy of 1.5eV. We show that the formation energy of adjacent pentagon pairs explains the diameter distribution in small-diameter nanotube samples grown by chemical vapor deposition.

description: This paper engages the question "Does the consistency of a set of axioms entail the existence of a model in which they are satisfied?" within the frame of the Frege-Hilbert controversy. The question is related historically to the formulation, proof, and reception of Gödel's Completeness Theorem. Tools from mathematical logic are then used to argue that there are precise senses in which Frege was correct to maintain that demonstrating consistency is as difficult as it can be but also in which Hilbert was correct to maintain that demonstrating existence given consistency is as easy as it can be.

description: A model is presented which calculates the gas temperature and chemistry in the surface layers of flaring circumstellar disks using a code developed for photon-dominated regions. Special attention is given to the influence of dust settling. It is found that the gas temperature exceeds the dust temperature by up to several hundreds of Kelvins in the part of the disk that is optically thin to ultraviolet radiation, indicating that the common assumption that Tgas=Tdust is not valid throughout the disk. In the optically thick part, gas and dust are strongly coupled and the gas temperature equals the dust temperature. Dust settling has little effect on the chemistry in the disk, but increases the amount of hot gas deeper in the disk. The effects of the higher gas temperature on several emission lines arising in the surface layer are examined. The higher gas temperatures increase the intensities of molecular and fine-structure lines by up to an order of magnitude, and can also have an important effect on the line shapes.

description: Gamma-ray bursts (GRBs) divide into two classes: "long", which typically have initial durations of T90>2s, and "short", with durations of T90<2s (where T90 is the time to detect 90% of the observed fluence). Long bursts, which on average have softer gamma-ray spectra, are known to be associated with with stellar core-collapse events-- in some cases simultaneously producing powerful Type Ic supernovae. In contrast, the origin of short bursts has remained mysterious until recently. A subsecond intense "spike" of gamma-rays during a giant flare from the Galactic soft gamma-ray repeater, SGR 1806-20, reopened an old debate over whether some short GRBs could be similar events seen in galaxies out to ~70Mpc (redshift z=0.016). Shortly after that, localizations of a few short GRBs (with optical afterglows detected in two cases) have shown an apparent association with a variety of host galaxies at moderate redshifts. Here we report a correlation between the locations of previously observed short bursts and the positions of galaxies in the local Universe, indicating that between 10 and 25 per cent of short GRBs originate at low redshifts (z<0.025).

Modelling and control of a hydrostatic transmission for a load-haul-dump underground-mining machine
Creators: name: Gosal, Amritpal Singh
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on the modelling and control of the hydrostatic transmission (HST) on an extremely-low-profile, front-end-loader configuration, load-haul-dump (LHD) machine: the 88XLP, designed and built by EJC Mining Equipment Inc. of Burlington, Ontario. The machine uses four pump-motor hydrostatic closed loops to power its four wheels. Speed regulation is required on such a machine in order to achieve the differential effect needed when the machine turns, as well as to maintain consistent wheel speeds and efficiency when travelling straight. Hydraulic pressure/flow sharing/coupling techniques are commonly employed to create the differential effect: experimental evaluation of eleven such hydraulic arrangements is presented to determine the efficacy of each, based on a calculation of a drivability-index for each arrangement. A review of techniques for feedback control of HSTs is presented, and proportional-integral (PI) control is selected to implement-speed feedback control for the variable-pump-variable-motor (PVMV) HST on the 88XLP. The results of tuning and drivability tests using the PI controller are presented. A model of the HST and controller, based on offline system-identification of the HST is implemented in Simulink, including nonlinearities, such as hysteresis and controller feedback quantization, as well as the discrete-time nature of the controller. It is found that this model does not provide close correspondence to behaviour of the actual system under feedback control. This discrepancy is attributable to the nature of the HST: its components with extremely nonlinear and time-varying characteristics, which further have a strong dependence on the operating conditions. As a result of the comparison between the various hydraulic sharing/coupling techniques and speed-feedback control, it is concluded that simple feedback control does not yield the best performance for this application, and that hydraulic system redesign is a more effective means of achieving design objectives for this application. The best performing hydraulic sharing/coupling technique is identified and suggestions are made to further improve its performance through simplifying the overall configuration of the HST.

description: Spider capture silk is a biomaterial with both high strength and high elasticity, but the structural design principle underlying these remarkable properties is still unknown. It was revealed recently by atomic force microscopy that, an exponential force--extension relationship holds both for capture silk mesostructures and for intact capture silk fibers [N. Becker et al., Nature Materials 2, 278 (2003)]. In this Letter a simple hierarchical chain model was proposed to understand and reproduce this striking observation. In the hierarchical chain model, a polymer is composed of many structural motifs which organize into structural modules and supra-modules in a hierarchical manner. Each module in this hierarchy has its own characteristic force. The repetitive patterns in the amino acid sequence of the major flagelliform protein of spider capture silk is in support of this model.

description: The distribution of the sum of independent identically distributed uniform random variables is well-known. However, it is sometimes necessary to analyze data which have been drawn from different uniform distributions. By inverting the characteristic function, we derive explicit formulae for the distribution of the sum of n non-identically distributed uniform random variables in both the continuous and the discrete case. The results, though involved, have a certain elegance. As examples, we derive from our general formulae some special cases which have appeared in the literature.

description: High impact epidemics constitute one of the largest threats humanity is facing in the 21st century. Testing, contact tracing and quarantining are critical in slowing down epidemic dynamics, but may prove insufficient for highly contagious diseases. In the absence of pharmaceutical interventions, physical distancing measures remain as the last resort to avoid a widespread outbreak. Here we show that such combined countermeasures drastically change the rules of the epidemic transition if testing capacities are limited: Instead of continuous the response to countermeasures becomes discontinuous and rather than following the conventional exponential growth, the outbreak accelerates and scales super-exponentially during an intermediate period. As a consequence, containment measures either suffice to stop the outbreak at low total case numbers or fail catastrophically if marginally too weak, thus implying large uncertainties in reliably estimating overall epidemic dynamics, both during initial phases and during second wave scenarios.

description: An important device for modulation and frequency translation in the field of circuit quantum electrodynamics is the IQ mixer, an analog component for which calibration is necessary to achieve optimal performance. In this paper, we introduce techniques originally developed for wireless communication applications to calibrate upconversion and downconversion mixers. A Kalman filter together with a controllable carrier frequency offset calibrates both mixers without removing them from the embedding measurement infrastructure. These techniques can be embedded into room temperature control electronics and they will find widespread use as circuit QED devices continue to grow in size and complexity.

description: Incorporating multiple camera views for detection alleviates the impact of occlusions in crowded scenes. In a multiview system, we need to answer two important questions when dealing with ambiguities that arise from occlusions. First, how should we aggregate cues from the multiple views? Second, how should we aggregate unreliable 2D and 3D spatial information that has been tainted by occlusions? To address these questions, we propose a novel multiview detection system, MVDet. For multiview aggregation, existing methods combine anchor box features from the image plane, which potentially limits performance due to inaccurate anchor box shapes and sizes. In contrast, we take an anchor-free approach to aggregate multiview information by projecting feature maps onto the ground plane (bird's eye view). To resolve any remaining spatial ambiguity, we apply large kernel convolutions on the ground plane feature map and infer locations from detection peaks. Our entire model is end-to-end learnable and achieves 88.2% MODA on the standard Wildtrack dataset, outperforming the state-of-the-art by 14.1%. We also provide detailed analysis of MVDet on a newly introduced synthetic dataset, MultiviewX, which allows us to control the level of occlusion.

description: The numerical implementation of the calculation of the crack propagation trajectory of brittle and fatigue fracture is considered. The trajectory is calculated based on the criteria of maximum tensile stresses, minimum strain energy density, maximum energy release and maximum triaxiality factor. Several common experiments on brittle fracture of samples of various geometries are considered. For each task, the trajectory calculation criteria were compared and the results were validated based on experimental data and calculations by other authors. It is shown that for isotropic materials, all the criteria considered give almost identical calculated crack trajectories.

description: In the context of Intelligent Transportation Systems and the delivery of goods, new technology approaches need to be developed in order to cope with certain challenges that last mile delivery entails, such as navigation in an urban environment. Autonomous delivery robots can help overcome these challenges. We propose a method for performing mixed reality (MR) simulation with ROS-based robots using Unity, which synchronizes the real and virtual environment, and simultaneously uses the sensor information of the real robots to locate themselves and project them into the virtual environment, so that they can use their virtual doppelganger to perceive the virtual world. Using this method, real and virtual robots can perceive each other and the environment in which the other party is located, thereby enabling the exchange of information between virtual and real objects. Through this approach a more realistic and reliable simulation can be obtained. Results of the demonstrated use-cases verified the feasibility and efficiency as well as the stability of implementing MR using Unity for ROS-based robots.

The balance functions in azimuthal angle is a measure of the transverse flow

description: The charge or barion number balance function in the relative azimuthal angle of a pair of particles emitted in ultrarelativistic heavy ion collisions is studied. The pi+pi- and ppbar balance functions are computed using thermal models with two different set of parameters, corresponding to a large freeze-out temperature and a moderate transverse flow or a small temperature and a large transverse flow. The single particle spectra including pions from resonance decays are similar for the two scenarios, on the other hand the azimuthal balance function is very different and could serve as an independent measure of the transverse flow at the freeze-out.

description: This article explores the similarities, differences, and implications from the 1970s–1980s experience for the macroeconomic dynamic that may arise from the 2008 price spike and subsequent recession. Role of monetary policy (deviations from Taylor rule) is assessed. This is an argument that has not been too prominent in public discourse about causes of the financial crisis or the policies undertaken to restore stability to financial markets and avoid an even deeper downturn than occurred. The ‘‘misery index’’ is compared across the past and recent macroeconomic events. Effects on agriculture of exchange rates are reviewed, effects dependent on currency values and interest rates that can change quickly and in unexpected ways.

description: We report on coherent control of excitation processes of translationally ultracold rubidium dimers in a magneto-optical trap by using shaped femtosecond laser pulses. Evolution strategies are applied in a feedback loop in order to optimize the photoexcitation of the Rb2 molecules, which subsequently undergo ionization or fragmentation. A superior performance of the resulting pulses compared to unshaped pulses of the same pulse energy is obtained by distributing the energy among specific spectral components. The demonstration of coherent control to ultracold ensembles opens a path to actively influence fundamental photo-induced processes in molecular quantum gases.

description: We study the perturbative structure of threshold enhanced logarithms in the coefficient functions of deep inelastic scattering (DIS) and semi-inclusive $e^+e^-$ annihilation (SIA) processes and setup a framework to sum them up to all orders in perturbation theory. Threshold logarithms show up as the distributions $((1-z)^{-1} \log^i(1-z))_+$ from the soft plus virtual (SV) and as logarithms $\log^i(1-z)$ from next to SV (NSV) contributions. We use the Sudakov differential and the renormalisation group equations along with the factorisation properties of parton level cross sections to obtain the resummed result which predicts SV as well as next to SV contributions to all orders in strong coupling constant. In Mellin $N$ space, we resum the large logarithms of the form $\log^i(N)$ keeping $1/N$ corrections. In particular, the towers of logarithms, each of the form $a_s^n/N^α\log^{2n-α} (N), a_s^n/N^α\log^{2n-1-α}(N) \cdots $ etc for $α=0,1$, are summed to all orders in $a_s$.

description: We present an empirical algorithm for obtaining photometric redshifts of quasars using 5-band Sloan Digital Sky Survey (SDSS) photometry. Our algorithm generates an empirical model of the quasar color-redshift relation, compares the colors of a quasar candidate with this model, and calculates possible photometric redshifts. Using the 3814 quasars of the SDSS Early Data Release Quasar Catalog to generate a median color-redshift relation as a function of redshift we find that, for this same sample, 83% of our predicted redshifts are correct to within |Delta z|<0.3. The algorithm also determines the probability that the redshift is correct, allowing for even more robust photometric redshift determination for smaller, more restricted samples. We apply this technique to a set of 8740 quasar candidates selected by the final version of the SDSS quasar-selection algorithm. The photometric redshifts assigned to non-quasars are restricted to a few well-defined values. In addition, 90% of the objects with spectra that have photometric redshifts between 0.8 and 2.2 are quasars with accurate (|Delta z|<0.3) photometric redshifts. Many of these quasars lie in a single region of color space; judicious application of color-cuts can effectively select quasars with accurate photometric redshifts from the SDSS database. When the SDSS is complete, this technique will allow the determination of photometric redshifts for ~10^6 faint SDSS quasar candidates, enabling advances in our knowledge of the quasar luminosity function, gravitational lensing of quasars, and correlations among quasars and between galaxies.

description: The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links, instability is transferred from energy markets to already volatile agricultural markets. In this article, we present empirical results using contemporary time-series analysis and Granger causality supplemented by a directed graph theory modeling approach to identify the links and plausible contemporaneous causal structures among energy and commodity variables. The results show that although there is a strong correlation among oil and commodity prices, the evidence for a causal link from oil to commodity prices is mixed.
Ergodicity recovery of random walk in heterogeneous disordered media

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Significant and persistent trajectory-to-trajectory variance are commonly observed in the particle tracking experiments, which have become a major challenge for the experiment data analysis. In this theoretical paper, we investigate the ergodicity recovery behavior, which helps to clarify the origin and the convergence of trajectory-to-trajectory fluctuation in various heterogeneous disordered media. The concepts of self-averaging and ergodicity are revisited in the context of trajectory analysis. The slow ergodicity recovery and the non-Gaussian diffusion in the annealed disordered media are shown as the consequences of the central limit theorem in different situations. The strange ergodicity recovery behavior is reported in the quenched disordered case, which arises from a localization mechanism. The first-passage approach is introduced to the ergodicity analysis for this case, of which the central limit theorem can be employed and the ergodicity is recovered in the length scale of diffusivity correlation.
