description: We measure the three-dimensional topology of large-scale structure in the Sloan Digital Sky Survey (SDSS). This allows the genus statistic to be measured with unprecedented statistical accuracy. The sample size is now sufficiently large to allow the topology to be an important tool for testing galaxy formation models. For comparison, we make mock SDSS samples using several state-of-the-art N-body simulations: the Millennium run of Springel et al. (2005)(10 billion particles), Kim & Park (2006) CDM models (1.1 billion particles), and Cen & Ostriker (2006) hydrodynamic code models (8.6 billion cell hydro mesh). Each of these simulations uses a different method for modeling galaxy formation. The SDSS data show a genus curve that is broadly characteristic of that produced by Gaussian random phase initial conditions. Thus the data strongly support the standard model of inflation where Gaussian random phase initial conditions are produced by random quantum fluctuations in the early universe. But on top of this general shape there are measurable differences produced by non-linear gravitational effects (cf. Matsubara 1994), and biasing connected with galaxy formation. The N-body simulations have been tuned to reproduce the power spectrum and multiplicity function but not topology, so topology is an acid test for these models. The data show a ``meatball'' shift (only partly due to the Sloan Great Wall of Galaxies; this shift also appears in a sub-sample not containing the Wall) which differs at the 2.5σlevel from the results of the Millennium run and the Kim & Park dark halo models, even including the effects of cosmic variance.

description: The low-energy electron-impact dissociation of molecular hydrogen has been a source of disagreement between various calculations and measurements for decades. Excitation of the ground state of H$_2$ into the dissociative $b ^3Σ_u^+$ state is now well understood, with the most recent measurements being in excellent agreement with the molecular convergent close-coupling (MCCC) calculations of both integral and differential cross sections (2018 Phys. Rev. A 98 062704). However, in the absence of similar measurements for vibrationally-excited or isotopically-substituted H$_2$, cross sections for dissociation of these species must be determined by theory alone. We have identified large discrepancies between MCCC calculations and the recommended $R$-matrix cross sections for dissociation of vibrationally-excited H$_2$, D$_2$, T$_2$, HD, HT, and DT (2002 Plasma Phys. Contr. F. 44 1263-1276,2217-2230), with disagreement in both the isotope effect and dependence on initial vibrational level. Here we investigate the source of the discrepancies, and discuss the consequences for plasma models which have incorporated the previously recommended data.

description: We selected a sample of a dozen blazars which are the prime candidates for simultaneous multi-wavelength observing campaigns in their outburst phase. We searched for optical outbursts, intra-day variability and short term variability in these blazars. We carried out optical photometric monitoring of nine of these blazars in 13 observing nights during our observing run October 27, 2006 - March 20, 2007 by using the 1.02 meter optical telescope. From our observations, our data favor the hypothesis that three blazars were in the outburst state; one blazar was in the post outburst state; three blazars were in the pre/post outburst state; one blazar was in the low-state; and the state of one blazar was not known because there is not much optical data available for the blazar to compare with our observations. Out of three nights of observations of AO 0235+164, intra-day variability was detected in two nights. Out of five nights of observations of S5 0716+714, intra-day variability was detected in two nights. In one night of observations of PKS 0735+178, intra-day variability was detected. Out of six nights of observations of 3C 454.3, intra-day variability was detected in three nights. No intra-day variability was detected in S2 0109+224, OJ 287, ON 231, 3C 279 and 1ES 2344+514 in their 1, 4, 1, 2 and 1 nights of observations respectively. AO 0235+164, S5 0716+714, OJ 287, 3C 279 and 3C 454.3 were observed in more than one night and short term variations in all these blazars were also noticed. From our observations and the available data, we found that the predicted optical outburst with the time interval of ~ 8 years in AO 0235+164 and ~ 3 years in S5 0716+714 have possibly occurred.

description: Electron tunneling through quantum-dots side coupled to a quantum wire, in equilibrium and nonequilibrium Kondo regime, is studied. The mean-field finite-$U$ slave-boson formalism is used to obtain the solution of the problem. We have found that the transmission spectrum shows a structure with two anti-resonances localized at the renormalized energies of the quantum dots. The DOS of the system shows that when the Kondo correlations are dominant there are two Kondo regimes with its own Kondo temperature. The above behavior of the DOS can be explained by quantum interference in the transmission through the two different resonance states of the quantum dots coupled to common leads. This result is analogous to the Dicke effect in optics. We investigate the many body Kondo states as a function of the parameters of the system.

description: We extend the available asymptotic theory for autoregressive sieve estimators to cover the case of stationary and invertible linear processes driven by independent identically distributed (i.i.d.) infinite variance (IV) innovations. We show that the ordinary least squares sieve estimates, together with estimates of the impulse responses derived from these, obtained from an autoregression whose order is an increasing function of the sample size, are consistent and exhibit asymptotic properties analogous to those which obtain for a finite-order autoregressive process driven by i.i.d. IV errors.  As these limit distributions cannot be directly employed for inference because they either may not exist or, where they do, depend on unknown parameters, a second contribution of the paper is to investigate the usefulness of bootstrap methods in this setting.  Focusing on three sieve bootstraps: the wild and permutation bootstraps, and a hybrid of the two, we show that, in contrast to the case of finite variance innovations, the wild bootstrap requires an infeasible correction to be consistent, whereas the other two bootstrap schemes are shown to be consistent (the hybrid for symmetrically distributed innovations) under general conditions.

description: We consider the decay of a false vacuum in circumstances where the methods suggested by Coleman run into difficulties. We find that in these cases quantum fluctuations play a crucial role. Namely, they naturally induce both an ultraviolet and infrared cutoff scales, determined by the parameters of the classical solution, beyond which this solution cannot be trusted anymore. This leads to the appearance of a broad class of new $O(4)$ invariant instantons, which would have been singular in the absence of an ultraviolet cutoff. We apply our results to a case where the potential is unbounded from below in a linear way and in particular show how the problem of small instantons is resolved by taking into account the inevitable quantum fluctuations.

description: The total red shift $z$ might be recast as a combination of the expansion red shift and a static shift due to the energy-momentum tensor non-conservation of a photon propagating through Electro-Magnetic (EM) fields. If massive, the photon may be described by the de Broglie-Proca (dBP) theory which satisfies the Lorentz(-Poincaré) Symmetry (LoSy) but not gauge-invariance. The latter is regained in the Standard-Model Extension (SME), associated with LoSy Violation (LSV) that naturally dresses photons of a mass. The non-conservation stems from the vacuum expectation value of the vector and tensor LSV fields. The final colour (red or blue) and size of the static shift depend on the orientations and strength of the LSV and EM multiple fields encountered along the path of the photon. Turning to cosmology, for a zero $Ω_Λ$ energy density, the discrepancy between luminosity and red shift distances of SNeIa disappears thanks to the recasting of $z$. Massive photons induce an effective dark energy acting `optically' but not dynamically.

Με τη Συνθήκη της Λωζάνης το 1923, οι μουσουλμάνοι της Θράκης εξαιρέθηκαν από την ανταλλαγή των πληθυσμών μεταξύ Ελλάδας και Τουρκίας, παρέμειναν στην περιοχή και συγκρότησαν τη μουσουλμανική μειονότητα της ελληνικής Θράκης, τη μόνη επίσημα αναγνωρισμένη μειονότητα από το ελληνικό κράτος. Σύμφωνα με τη Συνθήκη, εκτός από την πλήρη θρησκευτική ελευθερία η ελληνική πολιτεία είναι υποχρεωμένη να εξασφαλίζει ξεχωριστή εκπαίδευση για τα παιδιά της μουσουλμανικής μειονότητας της Δυτικής Θράκης. Η μειονοτική εκπαίδευση λειτουργεί παράλληλα με τη δημόσια και βασίζεται στις διακρατικές συμφωνίες μεταξύ Ελλάδας και Τουρκίας και διέπεται από ειδικούς νόμους της ελληνικής πολιτείας. Ο ευαίσθητος χώρος της μειονότητας, όμως, δεν έμεινε ανεπηρέαστος από τις διακυμάνσεις των ελληνοτουρκικών σχέσεων οι οποίες καθόριζαν ουσιαστικά τις παρεμβάσεις στον εκπαιδευτικό τομέα. Η έρευνά μου στοχεύει να προσεγγίσει αυτές τις διακυμάνσεις των ελληνοτουρκικών σχέσεων και την επίδραση που άσκησαν στην μειονοτική εκπαιδευτική πολιτική του ελληνικού κράτους.
description: The aim of this particular study is to present the Greek – Turkish relations and the educational policy of the Greek government towards the Muslim minority in Thrace in the years 1974 – 1996. Due to the Treaty of Lausanne in 1923, the Muslims of Thrace were excluded from the exchange of the population, which occurred between Greece and Turkey. They stayed in the area and formed the Muslim minority of Greek-Thrace, which is the only officially recognized minority by the Greek government. According to the Treaty, the Greek state is obliged to ensure not only the complete freedom of religion but also the separate, specialized education for the Muslim minority’s children in Southern Thrace. The education of the minority community has a parallel function with the state schools, it is based on the agreements made between the Greek and Turkish governments and it is governed by specific laws of the Greek state. This politically sensitive, minority area hasn’t been uninfluenced by the variations that have occurred in the Greek – Turkish relations and which have substantially determined the interferences in education. The aim of my research is to cast light upon the particular variations on the Greek – Turkish relations and the influ-ence they have on the Greek government’s minority educational policy.
Comment on "A compilation and bioenergetic evaluation of syntrophic microbial growth yields in anaerobic digestion" by Patón, M. and Rodríguez, J. [Water Research 162 (2019), 516-517]

description: Recent efforts have focused on providing a systematic analysis of syntrophic microbial growth yields. These biokinetic parameters are key to developing an accurate mathematical description of the anaerobic digestion process. The agreement between experimentally determined growth yields and those obtained from bioenergetic estimations is therefore of great interest. Considering five important syntrophic groups, including acetoclastic and hydrogenotrophic methanogens, as well as propionate, butyrate and lactate oxidizers, previous findings suggest that measured and estimated growth yields were consistent only for acetoclastic methanogens. A re-analysis revealed that data are also consistent for lactate oxidizers and hydrogenotrophic methanogens, whereas the limited data available for propionate and butyrate oxidizers are unsupportive of firm conclusions. These results highlight pertinent challenges in the analysis of microbial syntrophy and encourage more accurate measurements of syntrophic microbial growth yields in the future.

description: CH4 is proposed to be the starting point of a rich organic chemistry. Solid CH4 abundances have previously been determined mostly toward high mass star forming regions. Spitzer/IRS now provides a unique opportunity to probe solid CH4 toward low mass star forming regions as well. Infrared spectra from the Spitzer Space Telescope are presented to determine the solid CH4 abundance toward a large sample of low mass young stellar objects. 25 out of 52 ice sources in the $c2d$ (cores to disks) legacy have an absorption feature at 7.7 um, attributed to the bending mode of solid CH4. The solid CH4 / H2O abundances are 2-8%, except for three sources with abundances as high as 11-13%. These latter sources have relatively large uncertainties due to small total ice column densities. Toward sources with H2O column densities above 2E18 cm-2, the CH4 abundances (20 out of 25) are nearly constant at 4.7+/-1.6%. Correlation plots with solid H2O, CH3OH, CO2 and CO column densities and abundances relative to H2O reveal a closer relationship of solid CH4 with CO2 and H2O than with solid CO and CH3OH. The inferred solid CH4 abundances are consistent with models where CH4 is formed through sequential hydrogenation of C on grain surfaces. Finally the equal or higher abundances toward low mass young stellar objects compared with high mass objects and the correlation studies support this formation pathway as well, but not the two competing theories: formation from CH3OH and formation in gas phase with subsequent freeze-out.

Estimation and control of paper machine variables using wavelet packet analysis
Creators: name: Chun, John Byung-Kyu
Publisher: name: University of British Columbia
Year: 2009

description: The thesis discusses a new method in paper machine signal analysis using the wavelet packet transformation. It has been shown that this technique can be applied to three main areas in paper machine control such as the paper machine data analysis including estimation and compression, control of basis weight or moisture variations, and control performance monitoring. Compared to the traditional windowed Fourier transform, other filtering techniques, and wavelet transform, this method offers greater flexibility in analyzing signals with suitable time-frequency resolution. The Best Basis Algorithm has been introduced to obtain a best decomposition tree structure in decomposition of a given signal. The paper machine model for use in C D control has been derived from experimental bump test data. It has been clearly shown that the new method along with wavelet estimator produces results superior to standard analysis methods by reducing the error of estimation. In estimating more complex signals, however, the wavelet packet method is superior than the wavelet analysis since the best decomposition tree structure is chosen enabling the estimation to be more precise in the regions where frequency changes. When applied to industrial data, the wavelet packet estimation has provided more visual results by distinguishing the bump locations more evidently. Moreover, it has been shown that wavelet packet compression is more efficient than the wavelet case since it has achieved more compression ratio by yielding the combination of more zero coefficients and lesser mean square error. The thesis also presents the control scheme of the paper machine as well as an efficient technique to monitor the control performance on-line using both wavelets and wavelet packets. It has been shown that the calculation of performance index using the wavelet packet method is more precise since it offers finer frequency resolution.

description: As laser power has increased towards the petawatt region electromagnetic pulse (EMP) fields of up to 100kV/m have been recorded in the target chamber causing a real threat to the integrity of diagnostic instruments. The radiation, being in the100MHz to >1GHz frequency band also causes more widespread interference in thelaser facility. Recent work at Lawrence Livermore National Laboratory [1] points thefinger at the flux of high energy (MeV) electrons leaving the target as the primarycause of the EMP. In this report we analyse a general physical model of the modalityof the process which couples the two phenomena with the aim of devising mitigatingstrategies.

description: Photocurrent generation is studied in a system composed of a quantum wire with side-coupled quantum rings. The current generation results from the interplay of the particular geometry of the system and the use of circularly polarized radiation. We study the energy-momentum conservation for optical transitions involving electrons moving forwards and backwards in the wire. Due to the lack of time-reversal symmetry in the radiation, the optical transitions depend on the direction of motion of the electrons, leading to a current at zero bias voltage. The photocurrent increases with the number of rings within a wide range of physical parameters. A weak non-linear dependence of the current in the number of rings, related to quantum interference effects, is also predicted. This geometry suggests a scalable method for the generation of sizeable photocurrents based on nanoscale components.

description: Using a field-theoretical representation of the Tanaka-Edwards integral we develop a method to systematically compute the number N_s of 1-spin-stable states (local energy minima) of a glassy Ising system with nearest-neighbor interactions and random Gaussian couplings on an arbitrary graph. In particular, we use this method to determine N_s for K-regular random graphs and d-dimensional regular lattices for d=2,3. The method works also for other graphs. Excellent accuracy of the results allows us to observe that the number of local energy minima depends mainly on local properties of the graph on which the spin glass is defined.

description: The principal rank-one (RO) components of an image represent the self-similarity of the image, which is an important property for image restoration. However, the RO components of a corrupted image could be decimated by the procedure of image denoising. We suggest that the RO property should be utilized and the decimation should be avoided in image restoration. To achieve this, we propose a new framework comprised of two modules, i.e., the RO decomposition and RO reconstruction. The RO decomposition is developed to decompose a corrupted image into the RO components and residual. This is achieved by successively applying RO projections to the image or its residuals to extract the RO components. The RO projections, based on neural networks, extract the closest RO component of an image. The RO reconstruction is aimed to reconstruct the important information, respectively from the RO components and residual, as well as to restore the image from this reconstructed information. Experimental results on four tasks, i.e., noise-free image super-resolution (SR), realistic image SR, gray-scale image denoising, and color image denoising, show that the method is effective and efficient for image restoration, and it delivers superior performance for realistic image SR and color image denoising.

description: Some years ago it was shown that, in some cases, a notion of locality can arise from the group of symmetry enjoyed by the theory, thus in an intrinsic way. In particular, when Moebius covariance is present, it is possible to associate some particular transformations to the Tomita Takesaki modular operator and conjugation of a specific interval of an abstract circle. In this context we propose a way to define an operator representing the coordinate conjugated with the modular transformations. Remarkably this coordinate turns out to be compatible with the abstract notion of locality. Finally a concrete example concerning a quantum particle on a line is also given.

description: In this report we dive into the daunting looking world of revision control systems, aka source code control systems or source code management systems. Keeping track of changes in fles is something that most software developers want to do. It allows us to see which files were changed if a bug is spotted or results differ from one version of the software to the next. Attempting to do this with file and directory names is guaranteed to fail (well nearly) and consumes time that could be better used developing the software. The tools we will introduce in this note are designed to help software developers do away with manual control and provide easy access to files and their histories. We will discuss the benefits of revision control, introduce the tools and give use cases for each that illustrate how they can be used.

description: The natural impedance, or dynamic relationship between force and motion, of a human operator can determine the stability of exoskeletons that use interaction-torque feedback to amplify human strength. While human impedance is typically modelled as a linear system, our experiments on a single-joint exoskeleton testbed involving 10 human subjects show evidence of nonlinear behavior: a low-frequency asymptotic phase for the dynamic stiffness of the human that is different than the expected zero, and an unexpectedly consistent damping ratio as the stiffness and inertia vary. To explain these observations, this paper considers a new frequency-domain model of the human joint dynamics featuring complex value stiffness comprising a real stiffness term and a hysteretic damping term. Using a statistical F-test we show that the hysteretic damping term is not only significant but is even more significant than the linear damping term. Further analysis reveals a linear trend linking hysteretic damping and the real part of the stiffness, which allows us to simplify the complex stiffness model down to a 1-parameter system. Then, we introduce and demonstrate a customizable fractional-order controller that exploits this hysteretic damping behavior to improve strength amplification bandwidth while maintaining stability, and explore a tuning approach which ensures that this stability property is robust to muscle co-contraction for each individual.

title: How much patience do you have? A worst-case perspective on smooth nonconvex optimization

description: We consider the worst-case behaviour of algorithms for smooth non-convex nonlinear optimization. We examine the question of how many function and derivative evaluations might be required to find a point at which a suitable measures of first- and second-order criticality is smaller than a user-given tolerance _. While many popular algorithms can be shown to take O(_?2) evaluations in the worst-case—and there are examples for which this pessimistic bound is achieved—suitable regularized variants of Newton’s method may reduce this to O(_?3/2) evaluations. Progressively improved bounds are possible if the problem is convex or strictly convex. While such bounds were first established in the unconstrained case, the presence of constraints does not significantly alter the picture. We survey the crucial developments in this active area of research.

description: High-resolution data are desired in many data-driven applications; however, in many cases only data whose resolution is lower than expected are available due to various reasons. It is then a challenge how to obtain as much useful information as possible from the low-resolution data. In this paper, we target interval energy data collected by Advanced Metering Infrastructure (AMI), and propose a Super-Resolution Reconstruction (SRR) approach to upsample low-resolution (hourly) interval data into higher-resolution (15-minute) data using deep learning. Our preliminary results show that the proposed SRR approaches can achieve much improved performance compared to the baseline model.

description: Recently the Milagro experiment observed diffuse multi-TeV gamma-ray emission in the Cygnus region, which is significantly stronger than what predicted by the Galactic cosmic ray model. However, the sub-GeV observation by EGRET shows no excess to the prediction based on the same model. This TeV excess implies possible high energy cosmic rays populated in the region with harder spectrum than that observed on the Earth. In the work we studied this theoretical speculation in detail. We find that, a diffuse proton source with power index $α_p\lesssim 2.3$, or a diffuse electron source with power index $α_e\lesssim2.6$ can reproduce the Milagro's observation without conflicting with the EGRET data. Further detections on neutrinos, a diagnostic of the hadronic model, and hard X-ray synchrontron radiation, a diagnostic of the lepton model, help to break this degeneracy. In combination with the gamma ray observations to several hundred GeV by Fermi, we will be able to understand the diffuse emission mechanisms in the Cygnus region better.

description: Beyond 5G networks are expected to support massive traffic through decentralized solutions and advanced networking mechanisms. This paper aims at contributing towards this vision through the integration of device-centric wireless networks, including Device-to-Device (D2D) communications, and the Next Generation of Opportunistic networking (NGO). This integration offers multiple communication modes such as opportunistic cellular and opportunistic D2D-aided communications. Previous studies have demonstrated the potential and benefits of this integration in terms of energy efficiency, spectral efficiency and traffic offloading. We propose an integration of device-centric wireless networks and NGO that is not driven by a precise knowledge of the presence of the links. The proposed technique utilizes a novel concept of graph to model the evolution of the networking conditions and network connectivity. Uncertainties and future conditions are included in the proposed graph model through anticipatory mobile networking to estimate the transmission energy cost of the different communication modes. Based on these estimates, the devices schedule their transmissions using the most efficient communication mode. These decisions are later revisited in real-time using more precise knowledge about the network state. The conducted evaluation shows that the proposed technique significantly reduces the energy consumption (from 60% to 90% depending on the scenario) compared to traditional single-hop cellular communications and performs closely to an ideal oracle based system with full knowledge of present and future events. The transmission and computational overheads of the proposed technique show small impact on such energy gains.
