description: We present rotation curves for 19, mostly luminous, early-type disk galaxies. Rotation velocities are measured from a combination of HI velocity fields and long-slit optical emission line spectra along the major axis. We find that the rotation curves generally rise rapidly in the central regions and often reach rotation velocities of 200 - 300 km/s within a few hundred parsecs of the centre. The detailed shape of the central rotation curves shows a clear dependence on the concentration of the stellar light distribution and the bulge-to-disk luminosity ratio: galaxies with highly concentrated stellar light distributions reach the maximum in their rotation curves at relatively smaller radii than galaxies with small bulges and a relatively diffuse light distribution. We interpret this as a strong indication that the dynamics in the central regions are dominated by the stellar mass. At intermediate radii, many rotation curves decline. The strength of the decline is correlated with the total luminosity of the galaxies, more luminous galaxies having on average more strongly declining rotation curves. At large radii, however, all declining rotation curves flatten out, indicating that substantial amounts of dark matter must be present in these galaxies too. A comparison of our rotation curves with the Universal Rotation Curve from Persic et al. (1996) reveals large discrepancies between the observed and predicted rotation curves; we argue that rotation curves form a multi-parameter family which is too complex to describe with a simple formula depending on total luminosity only.

description: In this paper we investigate when a finite sum of products of two Toeplitz operators with quasihomogeneous symbols is a finite rank perturbation of another Toeplitz operator on the Bergman space. We discover a noncommutative convolution $\diamond$ on the space of quasihomogeneous functions and use it in solving the problem. Our main results show that if $F_j, G_j$ ($1\leq j\leq N$) are polynomials of $z$ and $\bar{z}$ then $\sum_{j=1}^{N}T_{F_j}T_{G_j}-T_{H}$ is a finite rank operator for some $L^{1}$-function $H$ if and only if $\sum_{j=1}^{N}F_j\diamond G_j$ belongs to $L^1$ and $H=\sum_{j=1}^{N}F_j\diamond G_j$. In the case $F_j$'s are holomorphic and $G_j$'s are conjugate holomorphic, it is shown that $H$ is a solution to a system of first order partial differential equations with a constraint.

description: The magnetic phase diagram of the ferromagnetic Kondo lattice model is determined at T=0 in 1D, 2D, and 3D for various magnitudes of the quantum mechanical localized spins ranging from S=1/2 to classical spins. We consider the ferromagnetic phase, the paramagnetic phase, and the ferromagnetic/antiferromagnetic phase separated regime. There is no significant influence of the spin quantum number on the phase boundaries except for the case S=1/2, where the model exhibits an instability of the ferromagnetic phase with respect to spin disorder. Our results give support, at least as far as the low temperature magnetic properties are concerned, to the classical treatment of the S=3/2-spins in the intensively investigated manganites, for which the ferromagnetic Kondo-lattice model is generally employed to account for magnetism.

Population code modelling of grating detectability along the apparent motion path

Publisher: name: F1000Research

description: The present study examined contrast detection of a grating along the path of apparent motion. We observed strong masking of grating detectability. Moreover, we found that masking was tuned for orientation: masking decreased when the difference between the orientation of the target and the motion-inducing stimuli increased. This suggests that masking is related to activation in primary visual cortex. However, apparent motion masking was observed to be strongest at high contrast levels. Using a standard gain control model, we were able to demonstrate that such masking is only possible in a model which assumes strong suppression in V1 at the target location induced by apparent motion, instead of an increase in V1 activation.

description: The large data size and dimensionality of hyperspectral data demands complex processing and data analysis. Multispectral data do not suffer the same limitations, but are normally restricted to blue, green, red, red edge, and near infrared bands. This study aimed to identify the optimal set of spectral bands for nitrogen detection in grape leaves using ensemble feature selection on hyperspectral data from over 3,000 leaves from 150 Flame Seedless table grapevines. Six machine learning base rankers were included in the ensemble: random forest, LASSO, SelectKBest, ReliefF, SVM-RFE, and chaotic crow search algorithm (CCSA). The pipeline identified less than 0.45% of the bands as most informative about grape nitrogen status. The selected violet, yellow-orange, and shortwave infrared bands lie outside of the typical blue, green, red, red edge, and near infrared bands of commercial multispectral cameras, so the potential improvement in remote sensing of nitrogen in grapevines brought forth by a customized multispectral sensor centered at the selected bands is promising and worth further investigation. The proposed pipeline may also be used for application-specific multispectral sensor design in domains other than agriculture.

CP violation in mixing and oscillations for leptogenesis with quasi-degenerate neutrinos

Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the sources of CP violation for baryogenesis models with quasi-degenerate neutrinos. Our approach is to use the renormalized propagator in a quantum field theory model of neutrino oscillations, paying close attention to unitarity requirements. From the probabilities of lepton number violating processes obtained in this way, we derive a source term for the time evolution of the lepton asymmetry. The source term has contributions that can be identified with CP violation from mixing, oscillations and interference between both. Given that this source term does not involve processes with unstable particles in the initial or final states, neither does it require to calculate number densities of neutrinos, no subtraction of real intermediate states must be performed. In equilibrium the source term is null, as demanded by unitarity and CPT invariance, due to a cancellation between the terms coming from CP violation in mixing and oscillations. The calculations are done in a simple scalar toy model, and the resummed propagator is diagonalized at first order in the decay widths over the mass difference. We also comment on the effect of the interference term, which is mild at the order we work, but seems to become more important with increasing degeneracy.

Development of a computer-controlled device to quantitatively measure the degree of spasticity at a subject’s ankle
Creators: name: Aitchison, Jeffrey R.
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this thesis project was to develop a device to quantitatively measure the degree of spasticity at a subject's ankle, and to use this device to find a means to determine a quantified measure of spasticity. The device imposes a controlled passive rotation of a subject's ankle joint, while simultaneously recording the resulting resistive torque and associated electromyographic (EMG) muscle activity. Comparative analysis of Data from subjects with and without spasticity were compared to identify response characteristics and parameters which could be associated with the presence and/or severity of spasticity. These differences were evaluated by modeling the data with a mathematical equation representing spasticity response. Parameters of the equation were then analyzed, and two of the four parameters deemed to be robust, reliable indicators of spasticity, were plotted to create a diagnostic model and curve for distinguishing between test subjects with and without spasticity. The perpendicular distance of the data points from the model curve can then be utilized as a quantified measure of spasticity. This quantified measure of spasticity was found to correlate with clinical evaluations. The analysis of variance test determined a 7.8 % probability that the sets of data, from subjects with and without spasticity, were from the same population, indicating that there was a significant difference between the two data sets. Thus it is concluded that a diagnostic model has been developed which shows potential as a means to quantify spasticity.
Cascade and Damping of Alfvén-Cyclotron Fluctuations: Application to Solar Wind Turbulence Spectrum

description: With the diffusion approximation, we study the cascade and damping of Alfvén-cyclotron fluctuations in solar plasmas numerically. Motivated by wave-wave couplings and nonlinear effects, we test several forms of the diffusion tensor. For a general locally anisotropic and inhomogeneous diffusion tensor in the wave vector space, the turbulence spectrum in the inertial range can be fitted with power-laws with the power-law index varying with the wave propagation direction. For several locally isotropic but inhomogeneous diffusion coefficients, the steady-state turbulence spectra are nearly isotropic in the absence of damping and can be fitted by a single power-law function. However, the energy flux is strongly polarized due to the inhomogeneity that leads to an anisotropic cascade. Including the anisotropic thermal damping, the turbulence spectrum cuts off at the wave numbers, where the damping rates become comparable to the cascade rates. The combined anisotropic effects of cascade and damping make this cutoff wave number dependent on the wave propagation direction, and the propagation direction integrated turbulence spectrum resembles a broken power-law, which cuts off at the maximum of the cutoff wave numbers or the $^4$He cyclotron frequency. Taking into account the Doppler effects, the model can naturally reproduce the broken power-law wave spectra observed in the solar wind and predicts that a higher break frequency is aways accompanied with a greater spectral index change that may be caused by the increase of the Alfvén Mach number, the reciprocal of the plasma beta, and/or the angle between the solar wind velocity and the mean magnetic field. These predictions can be tested by future observations.

description: We give an overview of the present status of knowledge of the production of J/psi, psi' and Upsilon in high-energy hadron collisions. We first present two early models, namely the Colour-Singlet Model (CSM) and the Colour-Evaporation Model (CEM). The first is the natural application of pQCD to quarkonium production and has been shown to fail dramatically to describe data, the second is its phenomenological counterpart and was introduced in the spirit of the quark-hadron duality in the late seventies. Then, we expose the most recent experimental measurements of J/psi, psi' and Upsilon prompt and direct production at nonzero p_T from two high-energy hadron colliders, the Tevatron and RHIC. In a third part, we review six contemporary models describing J/psi, psi' and Upsilon production at nonzero p_T.

description: This work justifies the paradigmatic importance of viscoelastic subdiffusion in random environments for cellular biological systems. This model displays several remarkable features, which makes it an attractive paradigm to explain the physical nature of biological subdiffusion. In particular, it combines viscoelasticity with distinct non-ergodic features. We extend this model to make it suitable for the subdiffusion of lipids in disordered biological membranes upon including the inertial effects. For lipids, the inertial effects occur in the range of picoseconds, and a power-law decaying viscoelastic memory extends over the range of several nanoseconds. Thus, in the absence of disorder, diffusion would become normal on a time scale beyond this memory range. However, both experimentally and in some molecular-dynamical simulations, the time range of lipid subdiffusion extends far beyond the viscoelastic memory range. We study three 1d models of correlated quenched Gaussian disorder to explain the puzzle: singular short-range (exponentially correlated), smooth short-range (Gaussian-correlated), and smooth long-range (power-law correlated) disorder. For a moderate disorder strength, transient viscoelastic subdiffusion changes into the subdiffusion caused by the randomness of the environment. It is characterized by a time-dependent power-law exponent of subdiffusion, which can show nonmonotonous behavior, in agreement with some recent molecular-dynamical simulations. Moreover, the spatial distribution of test particles in this disorder-dominated regime is shown to be a non-Gaussian, exponential power distribution, which also correlates well with molecular-dynamical findings and experiments. Furthermore, this subdiffusion is nonergodic with single-trajectory averages showing a broad scatter, in agreement with experimental observations for subdiffusion of various particles in living cells.

description: This thesis offers a new approach to understanding, and dealing with, the Rwandan Hutu refugee warrior groups who operate in the Kivu provinces of the Democratic Republic of the Congo. Through an integrated analysis of local Kivutian and national Congolese conflict dynamics, I examine the structures of violence within which Rwandan Hutu refugee warriors operate, and demonstrate how Rwandan Hutu refugees in the Kivus are following in the footsteps of other refugee warrior groups in the region. These much-maligned and marginalized Rwanda Hutu groups have faced nearly two decades of existential threats. Yet, despite extensive operations to remove them from the Kivus, they have managed to evade capture, remain in the Congo, and pursue belligerent activities there. I argue that the failure to reduce the threat of Rwandan Hutu refugee warrior groups can be attributed to a dearth of understanding about their strategies and motivations. In this thesis, I suggest a way of shedding light on significant aspects of refugee warriors' operational strategies by analyzing their refugee experience, and the subsequent impact this has on their identity and security decisions. I offer a theoretical framework for analysing refugee identity and apply it to the Rwandan Hutu refugee warriors operating in the Kivus. From this analysis, I suggest the need for a new strategy when it comes to dealing with the threat that Rwandan Hutus pose to the security of both Rwanda and the Congo, and advocate an approach which is more empathetic to the security concerns of Rwandan Hutus in exile. It is hope that transforming Rwandan Hutu militants from refugee warriors into legitimate political actors in both the Congo and Rwanda will provide a durable solution to the threat that they pose, and that this will have knock~on effects which reduce the overall militarization of the eastern Congo.

description: The conventional spin dynamics simulations are performed in direct products of state spaces of individual spins. In a general system of n spins, the total number of elements in the state basis is >4^n. A system propagation step requires an action by an operator on the state vector and thus requires >4^2n multiplications. It is obvious that with current computers there is no way beyond about ten spins, and the calculation complexity scales exponentially with the spin system size. We demonstrate that a polynomially scaling algorithm can be obtained if the state space is reduced by neglecting unimportant or unpopulated spin states. The class of such states is surprisingly wide. In particular, there are indications that very high multi-spin orders can be dropped completely, as can all the orders linking the spins that are remote on the interaction graph.

description: Tracking the formation and evolution of dark matter haloes is a critical aspect of any analysis of cosmological $N$-body simulations. In particular, the mass assembly of a halo and its progenitors, encapsulated in the form of its merger tree, serves as a fundamental input for constructing semi-analytic models of galaxy formation and, more generally, for building mock catalogues that emulate galaxy surveys. We present an algorithm for constructing halo merger trees from AbacusSummit, the largest suite of cosmological $N$-body simulations performed to date consisting of nearly 60 trillion particles, and which has been designed to meet the Cosmological Simulation Requirements of the Dark Energy Spectroscopic Instrument (DESI) survey. Our method tracks the cores of haloes to determine associations between objects across multiple timeslices, yielding lists of halo progenitors and descendants for the several tens of billions of haloes identified across the entire suite. We present an application of these merger trees as a means to enhance the fidelity of AbacusSummit halo catalogues by flagging and "merging" haloes deemed to exhibit non-monotonic past merger histories. We show that this cleaning technique identifies portions of the halo population that have been deblended due to choices made by the halo finder, but which could have feasibly been part of larger aggregate systems. We demonstrate that by cleaning halo catalogues in this post-processing step, we remove potentially unphysical features in the default halo catalogues, leaving behind a more robust halo population that can be used to create highly-accurate mock galaxy realisations from AbacusSummit.

description: In this work, we investigate the phenomenon that robust image classifiers have human-recognizable features -- often referred to as interpretability -- as revealed through the input gradients of their score functions and their subsequent adversarial perturbations. In particular, we demonstrate that state-of-the-art methods for adversarial training incorporate two terms -- one that orients the decision boundary via minimizing the expected loss, and another that induces smoothness of the classifier's decision surface by penalizing the local Lipschitz constant. Through this demonstration, we provide a unified discussion of gradient and Jacobian-based regularizers that have been used to encourage adversarial robustness in prior works. Following this discussion, we give qualitative evidence that the coupling of smoothness and orientation of the decision boundary is sufficient to induce the aforementioned human-recognizability phenomenon.

description: Miniature fluorescence microscopes are a standard tool in systems biology. However, widefield miniature microscopes capture only 2D information, and modifications that enable 3D capabilities increase the size and weight and have poor resolution outside a narrow depth range. Here, we achieve the 3D capability by replacing the tube lens of a conventional 2D Miniscope with an optimized multifocal phase mask at the objective's aperture stop. Placing the phase mask at the aperture stop significantly reduces the size of the device, and varying the focal lengths enables a uniform resolution across a wide depth range. The phase mask encodes the 3D fluorescence intensity into a single 2D measurement, and the 3D volume is recovered by solving a sparsity-constrained inverse problem. We provide methods for designing and fabricating the phase mask and an efficient forward model that accounts for the field-varying aberrations in miniature objectives. We demonstrate a prototype that is 17 mm tall and weighs 2.5 grams, achieving 2.76 $μ$m lateral, and 15 $μ$m axial resolution across most of the 900x700x390 $μm^3$ volume at 40 volumes per second. The performance is validated experimentally on resolution targets, dynamic biological samples, and mouse brain tissue. Compared with existing miniature single-shot volume-capture implementations, our system is smaller and lighter and achieves a more than 2x better lateral and axial resolution throughout a 10x larger usable depth range. Our microscope design provides single-shot 3D imaging for applications where a compact platform matters, such as volumetric neural imaging in freely moving animals and 3D motion studies of dynamic samples in incubators and lab-on-a-chip devices.

description: A two-dimensional system of atoms in an anisotropic optical lattice is studied theoretically. If the system is finite in one direction, it is shown to exhibit a transition between a two-dimensional superfluid and a one-dimensional Mott insulating chain of superfluid tubes. Monte Carlo simulations are consistent with the expectation that the phase transition is of Kosterlitz-Thouless type. The effect of the transition on experimental time-of-flight images is discussed.

description: The first part of this dissertation deals with the design and synthesis of silvestrol and rocaglamide derivatives exhibiting antiviral properties. These two natural products, which belong to the Flavagline group, were isolated from different species of the genus Aglaia. Due to their activity as selective translation inhibitors, they found application in previous medicinal chemistry research primarily as lead structures in cancer research, but later antiviral activity against a variety of RNA viruses was also demonstrated. In the present dissertation, several strategies for the total synthesis of this class of natural products were elaborated on the basis of previous work. This allowed the preparation of a library of 40 derivatives in total. The biological testing of 27 of these compounds against hepatitis E, which was carried out by collaborators at the Ruhr University Bochum, revealed new structure-activity relationships and confirmed that the correlations established in cancer research are also applicable to the antiviral properties. In addition, it was possible to identify candidates that exhibited both higher antiviral activity and proportionally lower cytotoxicity than both natural products. The second part of this dissertation deals with the development of novel synthetic methodologies in the field of radical chemistry. Based on a MINISCI-type decarboxylation, an access to synthetically useful alkoxyamines was established. The relevance of this method was demonstrated by its application in the context of a new total synthesis approach for (±)-indatraline. Studies on the reactivity of a polymer-bound bis(azido)iodiate(I) complex, which releases the highly explosive iodine azide in a controlled manner, enabled the elucidation of several previously unknown radical mechanisms. Furthermore, several methods have been developed to generate bromine azide from stable precursors in situ for the use in organic solvents to accomplish 1,2-functionalization of alkenes and chemoselective oxidation of secondary alcohols.

description: Im Jahr 2021 wurde in Deutschland die sogenannte CO2-Bepreisung fossiler Kraft- und Brennstoffe eingeführt, um deren Verbrauch zum Zwecke des Klimaschutzes zu reduzieren. Dieser Preisaufschlag auf fossile Energieträger wird in den kommenden Jahren sukzessive erhöht. Dieser Beitrag untersucht die Akzeptanz der CO2-Bepreisung für die Zeit vor Einführung des CO2-Preises im Jahr 2019. Eine Erhebung unter mehr als 6.000 Haushalten zeigt, dass eine leichte absolute Mehrheit von 53,7 % der Befragten grundsätzlich bereit ist, zu Klimaschutzzwecken höhere Kosten in Kauf zu nehmen. Die Zustimmung zu einer CO2-Bepreisung nimmt jedoch mit sinkendem Einkommen deutlich ab: Bei Befragten der untersten Einkommensgruppe liegt die Zustimmungsrate bei knapp unter 40 %. Erwartungsgemäß verringert sich die Zustimmung auch mit der Höhe des CO2-Preises. So wurde ein CO2-Preis von 50 Euro von einer Mehrheit der Befragten von 50,6 % abgelehnt. Um bei bis zum Jahr 2025 auf 55 Euro steigenden CO2-Preisen die mehrheitliche Akzeptanz der Bürger zu gewinnen, wird hier für einen breit angelegten Ausgleichsmechanismus durch die Reduzierung verzerrender und sozial ungerechter Steuern und Abgaben auf den Strompreis plädiert, die insbesondere Gering- und Durchschnittsverdienern zugutekommt. Andernfalls könnten die über die Zeit steigenden CO2-Preise eine hohe soziale Sprengkraft entfalten.

description: Das Ermüdungsversagen von Spannbetonbauteilen mit Spanngliedern aus mehrdrähtigen Litzenbündeln erfolgt i. d. R. drahtweise. Das Brechen solcher einzelner Spanndrähte kann unter Laborbedingungen akustisch sehr gut exakt erfasst werden. Hier wird untersucht, ob das Brechen der Spanndrähte schon kurz vorher akustisch messbar ist. Dies erfolgte über eine Körperschallanalyse mit 512 Frequenzen im Frequenzbereich 0.003 MHz – 1.562 MHz. Wir beschreiben hier eine Analyse-Möglichkeit, identifizieren Probleme dabei und machen Vorschläge für verbesserte zukünftige Analysen. Insbesondere war es von Nachteil, dass nur in einem zweistündigen Takt zweimal pro Stunde nur für ca. Sekunden gemessen werden konnte. Damit konnte kein Zusammenhang zu den Drahtbrüchen festgestellt werden. Allerdings ergab sich ein Zusammenhang zu einem Steifigkeitsparameter.

Dust in starburst nuclei and ULIRGs: SED models for observers
Creators: name: Siebenmorgen, Ralf

Subjects: subject: Astrophysics (astro-ph)

description: We provide a library of some 7000 SEDs (available at www.eso.org/~rsiebenm) for the nuclei of starburst and ultra luminous galaxies. Its purpose is to quickly obtain estimates of the basic parameters, such as luminosity, size and dust or gas mass and to predict the flux at yet unobserved wavelengths. The procedure is simple and consists of finding an element in the library that matches the observations. The objects may be in the local universe or at high z. We calculate the radiative transfer in spherical symmetry for a stellar cluster permeated by an interstellar medium with standard (Milky Way) dust properties. The cluster contains two stellar populations: old bulge stars and OB stars. Because the latter are young, a certain fraction of them will be embedded in compact clouds which constitute hot spots that determine the MIR fluxes. We present SEDs for a broad range of luminosities, sizes and obscurations. We argue that the assumption of spherical symmetry and the neglect of clumpiness of the medium are not severe shortcomings for computing the dust emission. The validity of the approach is demonstrated by matching the SED of seven of the best studied galaxies, including M82 and Arp220, by library elements. In all cases, one finds an element which fits the observed SED very well, and the parameters defining the element are in full accord with what is known about the galaxy from detailed studies. We also compare our method of computing SEDs with other techniques described in the literature.

description: Microstructural dynamics in amorphous particle packings is commonly probed by quantifying particle displacements. While rigidity in particle packings emerges when displacement of particles are hindered, it is not obvious how the typically disordered displacement metrics connect to mechanical response. Particle rotations, in contrast, are much less sensitive to confinement effects, while still sensitive to the mechanics of the packing. So far, little attention has been paid to connect microscopic rotational motion to mechanics of athermal amorphous packings. We demonstrate through experimental measurements that particle packing mechanics can be directly linked to the rotational motion of even round particles in a sheared packing. Our results show that the diffusive nature of rotational dynamics is highly strain sensitive. Additionally, there is substantial spatial correlation in rotation dynamics that is a function of the particle friction and packing density. Analysis of our measurements reveals that particle rotation dynamics plays an essential role in amorphous material mechanics.
