description: The availability of language representations learned by large pretrained neural network models (such as BERT and ELECTRA) has led to improvements in many downstream Natural Language Processing tasks in recent years. Pretrained models usually differ in pretraining objectives, architectures, and datasets they are trained on which can affect downstream performance. In this contribution, we fine-tuned German BERT and German ELECTRA models to identify toxic (subtask 1), engaging (subtask 2), and fact-claiming comments (subtask 3) in Facebook data provided by the GermEval 2021 competition. We created ensembles of these models and investigated whether and how classification performance depends on the number of ensemble members and their composition. On out-of-sample data, our best ensemble achieved a macro-F1 score of 0.73 (for all subtasks), and F1 scores of 0.72, 0.70, and 0.76 for subtasks 1, 2, and 3, respectively.

description: We study synchronization in the context of network traffic on a $2-d$ communication network with local clustering and geographic separations. The network consists of nodes and randomly distributed hubs where the top five hubs ranked according to their coefficient of betweenness centrality (CBC) are connected by random assortative and gradient mechanisms. For multiple message traffic, messages can trap at the high CBC hubs, and congestion can build up on the network with long queues at the congested hubs. The queue lengths are seen to synchronize in the congested phase. Both complete and phase synchronization is seen, between pairs of hubs. In the decongested phase, the pairs start clearing, and synchronization is lost. A cascading master-slave relation is seen between the hubs, with the slower hubs (which are slow to decongest) driving the faster ones. These are usually the hubs of high CBC. Similar results are seen for traffic of constant density. Total synchronization between the hubs of high CBC is also seen in the congested regime. Similar behavior is seen for traffic on a network constructed using the Waxman random topology generator. We also demonstrate the existence of phase synchronization in real Internet traffic data.

description: Using deep Chandra and optical spectroscopic observations, we investigate an intriguing, young massive group, RXJ1648.7+6109, at z=0.376, and we combine these observations with previous measurements to fit the scaling relations of intermediate-redshift groups and poor clusters. RXJ1648 appears to be in an early stage of formation; while it follows X-ray scaling relations, its X-ray emission is highly elongated and it lacks a central, dominant BCG. Instead, RXJ1648 contains a central string of seven bright galaxies, which have a smaller velocity dispersion, are on average brighter, and have less star formation (lower EW([OII]) and EW(H_delta)) than other group galaxies. The 4-5 brightest galaxies in this string should sink to the center and merge through dynamical friction by z=0, forming a BCG consistent with a system of RXJ1648's mass even if 5-50% of the light is lost to an intracluster light component (ICL). The L_X-T_X relation for intermediate-redshift groups/poor clusters is very similar to the low-redshift cluster relation and consistent with the low-redshift group relation. In contrast, the L_X-sigma_v and sigma_v-T_X relations reveal that intermediate-redshift groups/poor clusters have significantly lower velocity dispersions for their X-ray properties compared to low-redshift systems, however the intermediate-redshift relations are currently limited to a small range in luminosity.

description: We investigate and compare the particle number fluctuations in the putative many-body localized (MBL) phase of a spinless fermion model with potential disorder and nearest-neighbor interactions with those in the non-interacting case (Anderson localization) and in effective models where only interaction terms diagonal in the Anderson basis are kept. We demonstrate that these types of simple effective models cannot account for the particle number fluctuations observed in the MBL phase of the microscopic model. This implies that assisted and pair hopping terms---generated when transforming the microscopic Hamiltonian into the Anderson basis---cannot be neglected. As a consequence, it appears questionable if the microscopic model possesses an exponential number of exactly conserved local charges. If such exactly conserved local charges do not exist, then particles are expected to ultimately delocalize for any finite disorder strength.

description: Cement is one of the most produced materials in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, to which it provides a cohesive strength that rapidly increases during setting. Understanding how such cohesion emerges has been a major obstacle to advances in cement science and technology. Here, we combine computational statistical mechanics and theory to demonstrate how cement cohesion results from the organization of interlocked ions and water, progressively confined in nano-slits between charged surfaces of Calcium-Silicate-Hydrates. Due to the water/ions interlocking, dielectric screening is drastically reduced and ionic correlations are proven significantly stronger than previously thought, dictating the evolution of the nano-scale interactions during cement hydration. By developing a quantitative analytical prediction of cement cohesion based on Coulombic forces, we reconcile a novel fundamental understanding of cement hydration with the fully atomistic description of the solid cement paste and open new paths for science and technologies of construction materials.

description: The work provides an exhaustive comparison of some representative families of topology optimization methods for 3D structural optimization, such as the Solid Isotropic Material with Penalization (SIMP), the Level-set, the Bidirectional Evolutionary Structural Optimization (BESO), and the Variational Topology Optimization (VARTOP) methods. The main differences and similarities of these approaches are then highlighted from an algorithmic standpoint. The comparison is carried out via the study of a set of numerical benchmark cases using industrial-like fine-discretization meshes (around 1 million finite elements), and Matlab as the common computational platform, to ensure fair comparisons. Then, the results obtained for every benchmark case with the different methods are compared in terms of computational cost, topology quality, achieved minimum value of the objective function, and robustness of the computations (convergence in objective function and topology). Finally, some quantitative and qualitative results are presented, from which, an attempt of qualification of the methods, in terms of their relative performance, is done.

description: The accurate characterisation of the spatial variability of soil properties is crucial for a reliable representation of soil hydrological processes in any hydrological model. However, soil properties exhibit large spatial heterogeneity and their correct characterisation remains a challenge.

This work investigates the impact of using two different soil property maps derived from local in situ data in the ability of the SWAT+ hydrological model to represent streamflow and soil moisture at the catchment scale. For this purpose, the algorithms Gap Statistic for Estimating the Number of Clusters (clusGap) and K-means are first combined to cluster the Chilean dataset CLSoilMaps with a spatial resolution of 100 metres. The available water capacity (AWC) and saturated hydraulic conductivity (Ks) are used to obtain 16 classes of soil properties. Second, the Digital Soil Open Land Map (DSOLMap, López-Ballesteros et al., 2023) development procedure was applied to the same Chilean SoilGrids-like maps to obtain 352 classes of soil properties. Third, the soil classes defined in the global-scale DSOLMap and HWSD v2.0 were collected in their original spatial resolution. The four different maps of soil properties were used in SWAT+ to simulate the main hydrological processes in the Cauquenes en Desembocadura River Basin. This Mediterranean catchment has an important spatial heterogeneity of soil properties and is dominated by exotic forest plantations, shrublands and grasslands. Gridded data from ERA5-Land and PMLv2 are used to provide additional estimates of soil moisture and actual evapotranspiration, respectively, which are compared with the corresponding daily values simulated by SWAT+ for the historical period 1981-2020.

This work illustrates the benefits and limitations of using state-of-the-art soil mapping techniques to evaluate different local soil input maps in the simulation of streamflows and soil moisture.

description: Presentation held at the zeroPM workshop on September 19, 2024. 

We demonstrated the utility of chemical ontologies for classifying compounds. Here, we created a organic chemistry ontology and classifying about 1.7 million poly and perfluorinated compounds (PFAS) found in scientific publications and patents (https://pubchem.ncbi.nlm.nih.gov/classification/#hid=134). These indexed publications were used to retrieve PFAS - Toxicity cooccurrences. The statistics of these coocurrences were than used to create a prediction system for PFAS compounds to aid risk management when dealing with these "forever" compounds.

description: Microgauss magnetic fields are observed in all galaxies at low and high redshifts. The origin of these intense magnetic fields is a challenging question in astrophysics. We show here that the natural plasma fluctuations in the primordial universe (assumed to be random), predicted by the Fluctuation-Dissipation-Theorem, predicts $\sim 0.034 μG$ fields over $\sim 0.3$ kpc regions in galaxies. If the dipole magnetic fields predicted by the Fluctuation-Dissipation-Theorem are not completely random, microgauss fields over regions $\gtrsim 0.34$ kpc are easily obtained. The model is thus a strong candidate for resolving the problem of the origin of magnetic fields in $\lesssim 10^{9}$ years in high redshift galaxies.

Neural Network-based fingerprinting for background music identification

description: Identifying background music in video-on-demand (VoD) content is complex, given the low background music levels, fluctuating dialogue, and various forms of audiodegradation. Moreover, the high presence of sound effects (SFX) in VoD audiovisual increases the errors in identifications since these SFX are often used in multipletracks, leading to wrong identifications of music in the case where a query and a reference share an SFX, but the music is different. Traditional audio fingerprintingis significantly challenged in this scenario, and a new approach is needed to deal with this data type.This thesis addresses some of these challenges in improving music identification in VoD content. The contributions of this thesis can be summarised as follows: First,I present CueSet, a carefully annotated dataset with real-world examples of VoD audio issues encountered in BMAT customers’ data. This dataset serves as a testdataset for VoD music identification. Second, I developed a new data pipeline integrating advanced audio augmentation techniques, including adding speech anddialogue features, into Neural Audio fingerprinting, the open-source SOTA audio fingerprinting system. This aims to simulate the challenging conditions typical ofVoD environments more accurately. Finally, I conducted three comprehensive experiments using this data augmentation pipeline to train a neural network-basedfingerprinting model. These efforts led to substantial improvements over existing baselines, with a +29.9% increase in precision, a +28.3% improvement in recall, anda +28% enhancement in F1-score in recognizing music in VoD content. However, the extensive use of augmentations introduced additional training complexities, requiringprecise model tuning to achieve optimal performance.Our experiments show that mixing music with speech as an augmentation during training effectively improves the robustness of background music identificationin VoD content. Other audio degradation techniques also helped to improve the system’s robustness, but their potential is only shown after a few adjustments inthe model. By emphasising the need for good-quality datasets and domain-specific, proper augmentations, we are taking significant steps towards improving audio identification technologies in industry avenues, offering hope for more effective solutions.
Technological change in the Fraser River salmon canning industry, 1871-1912
Creators: name: Stacey, Duncan A.
Publisher: name: University of British Columbia
Year: 2010

description: British Columbia's salmon industry is currently one of the province's major sources of income. Its development from a primitive fishery to a highly organized industrial operation has had many phases, one of the most significant occuring in the late 19th and early 20th centuries. In this period several technological developments freed the industry from expensive and unreliable manual labour and laid the basis for the modern industry's organization. This study investigates the innovations made in fishing, packing, and canning machinery and shows how intimately related these developments were to each other. A central point in this thesis is the argument that the industry's development at this time was not due to the introduction of a major invention (the "great man" theory applied to machines) but rather to a series of interlocking, mutually supporting innovations which tended to occur in clusters. Another point is that these innovations were called forth by chronic labour shortages which afflicted the province in its early history. Some space is also given to the effects of technology on the workers and canners of the period. Whenever possible primary source material has been used, including company records, letters and other papers of the early canners, early newspaper and periodical accounts, government reports and regulations of the time, and interviews with pioneers of the fishing industry. Secondary sources have, as much as possible, been restricted to clarification or supplementation of the original material.

We use a Witten diagram to combine the s-channel photo-excitation of holographic pentaquarks with a massive t-channel graviton or tensor glueball exchange, to extract the scattering amplitude for heavy meson photo-production in the threshold region. The pentaquark signal is too weak to be detected at current electron facilities.

description: Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be either parallel or perpendicular to the projection of the disc axis on the sky. As first pointed out by Stark and Connors in 1977, General Relativity effects strongly modify the polarization properties of the thermal radiation as observed at infinity. Among these effects, the rotation of the polarization angle with energy is particularly useful as a diagnostic tool. In this paper, we extend the Stark and Connors calculations by including the spectral hardening factor, several values of the optical depth of the scattering atmosphere and rendering the results to the expected performances of planned X-ray polarimeters. In particular, to assess the perspectives for the next generation of X-ray polarimeters, we consider the expected sensitivity of the detectors onboard the planned POLARIX and IXO missions. We assume the two cases of a Schwarzschild and an extreme Kerr black hole with a standard thin disc and a scattering atmosphere. We compute the expected polarization degree and the angle as functions of the energy as they could be measured for different inclinations of the observer, optical thickness of the atmosphere and different values of the black hole spin. We assume the thermal emission dominates the X-ray band. Using the flux level of the microquasar GRS 1915+105 in the thermal state, we calculate the observed polarization.

Modellbasierte Diagnose auf Basis Differential-Algebraischer Systeme mit Nichtlinearen Kalman-Filtern

Publisher: name: Universität Bielefeld
Year: 2021
Subjects: subject: 620

description: The model-based diagnosis is an approach for the characterizing of the behavior of a system in respect of an appropriately defined reference behavior. In this context, the reference behavior is described by mathematical models. This thesis considers the models formulated as Differential-Algebraic Equations (DAE) for the model-based diagnosis.

 The foundation for the development of the diagnosis methods is the state estimation with nonlinear Kalman-filters. Consequently, the state estimation approaches as well as the formulations of the Kalman-filters with nonlinear DAE are central parts of this thesis. The generalization of the Kalman-filter algorithm to nonlinear higher index DAE is a substantial contribution to the development of model-based approaches with models of this class. The basis for the formulations of the Kalman-filter is the discussion of the properties and solution methods of DAE.

 The diagnosis methods based on state estimation are treated. The hybrid state estimation, i.e. a simultaneous estimation of the continuous valued state and the discrete valued behavioral mode of the system is described in detail. Therefore, the Interacting Multiple Model (IMM) algorithm is introduced in-depth with focus on the practical application. Throughout the thesis, the system behavior is supposed to be described by nonlinear differential-algebraic equations and thus the approaches are formulated according to the model class.

 The methods referenced above are applied to a complex industrial plant within the framework of a research project. Thereby, the discussion of the approaches is intensified. Particularly, the practical relevance of the DAE and of the developed algorithms are illustrated. The mathematical modeling as well as the results achieved with the state estimation and the diagnosis are presented for a real system from the field of the industrial manufacturing.

However, so far, how to detect these quantum phases effectively remains an outstanding challenge. Here, we show that the optical Bragg scattering of cold atoms loaded on optical lattices can be used to detect many quantum phases which include not only the conventional superfluid and Mott insulating phases, but also other important phases such as various kinds of density waves (CDW), valence bond solids (VBS), CDW supersolids and VBS supersolids.

description: Measurements of CMB temperature fluctuations by the Wilkinson Microwave Anisotropy Probe (WMAP) indicate that the fluctuation amplitude in one half of the sky differs from the amplitude in the other half. We show that such an asymmetry cannot be generated during single-field slow-roll inflation without violating constraints to the homogeneity of the Universe. In contrast, a multi-field inflationary theory, the curvaton model, can produce this power asymmetry without violating the homogeneity constraint. The mechanism requires the introduction of a large-amplitude superhorizon perturbation to the curvaton field, possibly a pre-inflationary remnant or a superhorizon curvaton-web structure. The model makes several predictions, including non-Gaussianity and modifications to the inflationary consistency relation, that will be tested with forthcoming CMB experiments.

description: Using the linearly polarized intensity and polarization angle data at 3.6, 6.2 and 20 cm, we determine variations of Faraday rotation and depolarization across the nearby galaxy M33. A 3-D model of the regular magnetic field is fitted to the observed azimuthal distribution of polarization angles. Faraday rotation, measured between 3.6 and 6.2 cm at a linear resolution of 0.7 kpc, shows more variation in the south than in the north of the galaxy. About 10% of the nonthermal emission from M33 at 3.6 cm is polarized. We estimate the average total and regular magnetic field strengths in M33 as ~ 6.4 and 2.5 $μ$G, respectively. Under the assumption that the disk of M33 is flat, the regular magnetic field consists of horizontal and vertical components: however the inferred vertical field may be partly due to a galactic warp. The horizontal field is represented by an axisymmetric (m=0) mode from 1 to 3 kpc radius and a superposition of axisymmetric and bisymmetric (m=0+1) modes from 3 to 5 kpc radius. An excess of differential Faraday rotation in the southern half together with strong Faraday dispersion in the southern spiral arms seem to be responsible for the north-south asymmetry in the observed wavelength dependent depolarization. The presence of an axisymmetric m=0 mode of the regular magnetic field in each ring suggests that a galactic dynamo is operating in M33. The pitch angles of the spiral regular magnetic field are generally smaller than the pitch angles of the optical spiral arms but are twice as big as simple estimates based on the mean-field dynamo theory and M33's rotation curve. Generation of interstellar magnetic fields from turbulent gas motions in M33 is indicated by the equipartition of turbulent and magnetic energy densities.

description: We perform cosmological hydrodynamic simulations to determine to what extent galaxies lose their gas due to photoheating from an ionizing background. We find that the characteristic mass at which haloes on average have lost half of their baryons is Mc ~ 6.5 x 10^9 Msun/h at z = 0, which corresponds to a circular velocity of 25 km/s. This is significantly lower than the filtering mass obtained by the linear theory, which is often used in semianalytical models of galaxy formation. We demonstrate it is the gas temperature at the virial radius which determines whether a halo can accrete gas. A simple model that follows the merger history of the dark matter progenitors, and where gas accretion is not allowed when this temperature is higher than the virial temperature of the halo, reproduces the results from the simulation remarkably well. This model can be applied to any reionization history, and is easy to incorporate in semianalytical models.

description: We investigate the Hubbard model in the limit $U=\infty$, which is equivalent to the statistical condition of exclusion of double occupancy. We solve this problem using Dirac's method for constraints. The constraints are solved within the Bosonization method. We find that the constraints modify the anomalous commutator. We apply this theory to quantum wires at finite temperatures where the Hubbard interaction is $U=\infty$. We find that the anomalous commutator induced by the constraints gives rise to the 0.7 anomalous conductance.

description: The correlated motion of electrons in the presence of strong orbital fluctuations and correlations is investigated with respect to magnetic couplings and excitations in an orbitally degenerate ferromagnet. Introduction of the orbital degree of freedom results in a class of diagrams representing spin-orbital coupling which become particularly important near the orbital ordering instability. Low-energy staggered orbital fluctuation modes, particularly with momentum near (π/2,π/2,0) (corresponding to CE-type orbital correlations), are shown to generically yield strong intrinsically non-Heisenberg (1-\cos q)^2 magnon self energy correction, resulting in no spin stiffness reduction, but strongly suppressed zone-boundary magnon energies in the Gamma-X direction. The zone-boundary magnon softening is found to be strongly enhanced with increasing hole doping and for narrow-band materials, which provides insight into the origin of zone-boundary anomalies observed in ferromagnetic manganites.

description: We investigate a number of fermionic condensate phases on the honeycomb lattice, to determine whether topological defects (vortices and edges) in these phases can support bound states with zero energy. We argue that topological zero modes bound to vortices and at edges are not only connected, but should in fact be \emph{identified}. Recently, it has been shown that the simplest s-wave superconducting state for the Dirac fermion approximation of the honeycomb lattice at precisely half filling, supports zero modes inside the cores of vortices (P. Ghaemi and F. Wilczek, 2007). We find that within the continuum Dirac theory the zero modes are not unique neither to this phase, nor to half filling. In addition, we find the \emph{exact} wavefunctions for vortex bound zero modes, as well as the complete edge state spectrum of the phases we discuss. The zero modes in all the phases we examine have even-numbered degeneracy, and as such pairs of any Majorana modes are simply equivalent to one ordinary fermion. As a result, contrary to bound state zero modes in $p_x+i p_y$ superconductors, vortices here do \emph{not} exhibit non-Abelian exchange statistics. The zero modes in the pure Dirac theory are seemingly topologically protected by the effective low energy symmetry of the theory, yet on the original honeycomb lattice model these zero modes are split, by explicit breaking of the effective low energy symmetry.

$ϕ$ Meson Production in In-In Collisions and the $ϕ$ Puzzle

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The NA60 experiment measured dimuon production in In-In collisions at 158 AGeV. This paper presents a high statistics measurement of $ϕ\toμμ$ with the specific objective to provide insight on the $ϕ$ puzzle, i.e. the difference in the inverse $T$ slopes and absolute yields measured by NA49 and NA50 in the kaon and lepton channel, respectively. Transverse momentum distributions were studied as a function of centrality. The slope parameter $T$ shows a rapid increase with centrality, followed by a saturation. Variations of $T$ with the fit range of the order of 15 MeV were observed, possibly as a consequence of radial flow. The $ϕ$ meson yield normalized to the number of participants increases with centrality and is consistently higher than the yield measured by the NA49 experiment at any centrality.

description: We give a new proof of the sharp one weight $L^p$ inequality for any operator $T$ that can be approximated by Haar shift operators such as the Hilbert transform, any Riesz transform, the Beurling-Ahlfors operator. Our proof avoids the Bellman function technique and two weight norm inequalities. We use instead a recent result due to A. Lerner to estimate the oscillation of dyadic operators. Our method is flexible enough to prove the corresponding sharp one-weight norm inequalities for some operators of harmonic analysis: the maximal singular integrals associated to $T$, Dyadic square functions and paraproducts, and the vector-valued maximal operator of C. Fefferman-Stein. Also we can derive a very sharp two-weight bump type condition for $T$.
description: We improve different parts of the first version, in particular we show the sharpness of our theorem for the vector-valued maximal function
Dynamical supersymmetry in maximally supersymmetric gauge theories

description: Maximally supersymmetric theories can be described by a single scalar superfield in light-cone superspace. When they are also (super)conformally invariant, they are uniquely specified by the form of the dynamical supersymmetry. We present an explicit derivation of the light-cone superspace form of the dynamical supersymmetry in the cases of ten- and four-dimensional super-Yang-Mills, and the three-dimensional Bagger-Lambert-Gustavsson theory, starting from the covariant formulation of these theories.

description: Context: Most upcoming CMB polarization experiments will use direct imaging to search for the primordial gravitational waves through the B-modes. Bolometric interferometry is an appealing alternative to direct imaging that combines the advantages of interferometry in terms of systematic effects handling and those of bolometric detectors in terms of sensitivity. Aims: We calculate the signal from a bolometric interferometer in order to investigate its sensitivity to the Stokes parameters paying particular attention to the choice of the phase-shifting scheme applied to the input channels in order to modulate the signal. Methods: The signal is expressed as a linear combination of the Stokes parameter visibilities whose coefficients are functions of the phase-shifts. Results: We show that the signal to noise ratio on the reconstructed visibilities can be maximized provided the fact that the phase-shifting scheme is chosen in a particular way called coherent summation of equivalent baselines. As a result, a bolometric interferometer is competitive with an imager having the same number of horns, but only if the coherent summation of equivalent baselines is performed. We confirm our calculations using a Monte-Carlo simulation. We also discuss the impact of the uncertainties on the relative calibration between bolometers and propose a way to avoid this systematic effect.

Comparison of dog teams and polygraph in detecting "Guilt"
Creators: name: Ramirez Monzon, Carmen Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: A study was conducted to evaluate the ability of police dog teams to identify "guilty" subjects in a simulated crime situation and to compare their accuracy with that of a polygraph examination. Research on the olfactory acuity of dogs, and on the role of olfactory cues such as pheromones in social communication, implies that the detection of guilt by experienced police dogs could occur as reliably as police dog handlers believe. The literature on polygraph investigations shows high reliability in detecting guilt. This was one of the reasons for using the polygraph as the comparison technique. Three experienced dog teams from the Vancouver Police Dog Squad and two expert polygraph field examiners were used. The subjects were 64 male volunteers, all university or college students. Subjects randomly assigned to the "guilty" condition were instructed to "steal" and conceal a $10 bill that had been left in an empty office, and to deny throughout the rest of the experiment that they had done so. Volunteers in the "not guilty" condition were told nothing about the "crime" Both groups were told that police dog teams and polygraph operators would try to find out whether they were guilty. They were promised $5.00 for participating plus a bonus of $10 if they succeeded in establishing that they were innocent. Police dog team performance was about chance level, while the polygraph examination was significantly more accurate than chance and than the dog teams. No individual difference was found among the dog teams. The failure of the dog teams could be attributed either to the impossibility of detecting guilty by smell cues or to some aspect of the simulation procedure. Further research should be directed at developing more realistic field studies.
