description: We show the existence of intrinsic localized spins in mesoscopic high-mobility GaAs/AlGaAs heterostructures. Non-equilibrium transport spectroscopy reveals a quasi-regular distribution of the spins, and indicates that the spins interact indirectly via the conduction electrons. The interaction between spins manifests in characteristic zero-bias anomaly near the Fermi energy, and indicates gate voltage-controllable magnetic phases in high-mobility heterostructures. To address this issue further, we have also designed electrostatically tunable Hall devices, that allow a probing of Hall characteristics at the active region of the mesoscopic devices. We show that the zero field Hall coefficient has an anomalous contribution, which can be attributed to scattering by the localized spins. The anomalous contribution can be destroyed by an increase in temperature, source drain bias, or field range.

description: The rare $π^0 \to e^+e^-$ and $η\to μ^+μ^-$ decays are calculated in different schemes, which are seen to be essentially equivalent to and produce the same results as conventional Vector-Meson Dominance. We obtain the theoretical predictions $B(π^0 \to e^+e^-) = (6.41 \pm 0.19)\times 10^{-8}$ and $B(η\to μ^+μ^-) = (1.14 +0.06 -0.03) \times 10^{-5}$ in agreement with recent experimental data.

Violation of Rotational Invariance of Local Realistic Models with Two Settings

description: We have considered a two-particle Bell experiment to visualize the conflict between rotational invariance of physical laws and a specific local realistic theory. The experiment is reproducible by using a local realistic theory obtained in a two-setting Bell experiment. The generalized Bell inequality {[J. Phys. A: Math. Theor. {\bf 40}, 13101 (2007)]}, which is derived under the assumption that there exists a rotationally invariant local realistic theory, turns out to disprove such a local realistic model existing with a two-setting experiment. This implies that such a model is not rotationally invariant and should, therefore, be ruled out in some situations.

description: We determine explicitly all structure constants of the whole chiral BRST cohomology ring in $D=2$ string theory including both the discrete states and tachyon states. This is made possible by establishing several identities for Schur polynomials with operator argument and exploring associativity. Furthermore we find that the (chiral) symmetry algebra of the charges obtained by using the descent equations can actually be read off from the cohomology ring structure by simple operation involving the ghost field $b$. We also determine the enlarged symmetry algebra which contains the charges having ghost number $-1$ and $1$. Finally the complete symmetry transformation rules are derived for closed string discrete states by carefully combining the left and right sectors. It turns out that the new states introduced recently by Witten and Zwiebach are naturally created when symmetries act on the old states.

description: Given the abstract evolution equation \[ y'(t)=Ay(t),\ t\in \mathbb{R}, \] with scalar type spectral operator $A$ in a complex Banach space, found are conditions necessary and sufficient for all weak solutions of the equation, which a priori need not be strongly differentiable, to be strongly infinite differentiable on $\mathbb{R}$. The important case of the equation with a normal operator $A$ in a complex Hilbert space is obtained immediately as a particular case. Also, proved is the following inherent smoothness improvement effect explaining why the case of the strong finite differentiability of the weak solutions is superfluous: if every weak solution of the equation is strongly differentiable at $0$, then all of them are strongly infinite differentiable on $\mathbb{R}$.

Data-Driven Visual Forecasting

Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: Understanding the temporal dimension of images is a fundamental part of computer vision. Humans are able to interpret howthe entities in an image will change over time. However, it has only been relatively recently that researchers have focused on visual forecasting— getting machines to anticipate events in the visual world before they actually happen. This aspect of vision has many practical implications for tasks ranging from human-computer interaction to anomaly detection. In addition, temporal prediction can serve as a task for representation learning, useful for various other recognition problems. In this thesis, we focus on visual forecasting that is data-driven, self-supervised, and relies on little to no explicit semantic information. Towards this goal, we explore prediction at different timeframes. We first consider predicting instantaneous pixelmotion—optical flow. We apply convolutional neural networks to predict optical flow in static images. We then extend this idea to a longer timeframe, generalizing to pixel trajectory prediction in spacetime. We incorporate models such as variational autoencoders to generate future possible motions in the scene. After this, we consider a mid-level element approach to forecasting. By combining a Markovian reasoning framework with an intermediate representation, we are able to forecast events over longer timescales. This dissertation then builds upon these ideas towards structured representations for visual forecasting. Specifically, we aim to reason about the future of images in a structured state space. Instead of directly predicting events in a low-level feature space such as pixels or motion, we forecast events in a higher level representation that is still visually meaningful. This approach confers a number of advantages. It is not restricted by explicit timescales like motion-based approaches, and, unlike direct pixel-based approaches, predictions are less likely to “fall off” the manifold of the true visual world.

description: We study the effective interactions between Dirac fermions on the surface of a three-dimensional topological insulator due to the proximity coupling to the magnetic fluctuations in a ferromagnetic or antiferromagnetic insulator. Our results show that the magnetic fluctuations can mediate attractive interactions between Dirac fermions of both Amperean and BCS type. In the ferromagnetic case, we find pairing between fermions with parallel momenta, so-called Amperean pairing, whenever the effective Lagrangian for the magnetic fluctuations does not contain a quadratic term. The pairing interaction also increases with increasing Fermi momentum, and is in agreement with previous studies in the limit of high chemical potential. If a quadratic term is present, the pairing is instead of BCS type above a certain chemical potential. In the antiferromagnetic case, BCS pairing occurs when the ferromagnetic coupling between magnons on the same sublattice exceeds the antiferromagnetic coupling between magnons on different sublattices. Outside this region in parameter space, we again find that Amperean pairing is realized.

description: In this second paper on loop quantization of Gowdy model, we introduce the kinematical Hilbert space on which appropriate holonomies and fluxes are well represented. The quantization of the volume operator and the Gauss constraint is straightforward. Imposition of the Gauss constraint can be done on the kinematical Hilbert space to select subspace of gauge invariant states. We carry out the quantization of the Hamiltonian constraint making specific choices. Alternative choices are briefly discussed. It appears that to get spatial correlations reflected in the Hamiltonian constraint, one may have to adopt the so called `effective operator viewpoint'.

description: A weak version of the cosmic censorship hypothesis is implemented as a set of boundary conditions on exact semi-classical solutions of two-dimensional dilaton gravity. These boundary conditions reflect low-energy matter from the strong coupling region and they also serve to stabilize the vacuum of the theory against decay into negative energy states. Information about low-energy incoming matter can be recovered in the final state but at high energy black holes are formed and inevitably lead to information loss at the semi-classical level.

description: A recently described technique (Estes and Mayer, Biochim. Biophys. Acta 1712 (2005) 152--160) for the preparation of giant unilamellar vesicles (GUVs) in solutions with high ionic strength is examined. By observing a series of osmotic swellings followed by vesicle bursts upon a micropipette transfer of a single POPC GUV from a sucrose solution into an isoosmolar glycerol solution, a value for the permeability of POPC membrane for glycerol, P = (2.09+/-0.82) x 10^{-8} m/s, has been obtained. Based on this result, an alternative mechanism is proposed for the observed exchange of vesicle interior. With modifications, the method of Estes and Mayer is then applied to preparation of flaccid GUVs.

description: The Torpedo cluster, SPT-CL J0245-5302 (S0295) is a massive, merging cluster at a redshift of z = 0.300, which exhibits a strikingly similar morphology to the Bullet cluster 1E 0657-55.8 (z = 0.296), including a classic bow shock in the cluster's intra-cluster medium revealed by Chandra X-ray observations. We present Australia Telescope Compact Array data centred at 2.1 GHz and Murchison Widefield Array data at frequencies between 72 MHz and 231 MHz which we use to study the properties of the cluster. We characterise a number of discrete and diffuse radio sources in the cluster, including the detection of two previously unknown radio relics on the cluster periphery. The average spectral index of the diffuse emission between 70 MHz and 3.1 GHz is $α=-1.63_{-0.10}^{+0.10}$ and a radio-derived Mach number for the shock in the west of the cluster is calculated as M = 2.04. The Torpedo cluster is thus as a double relic system at moderate redshift.

description: Our answer is the latter. Space-time singularities, including the initial one, are described by world-sheet topological Abelian gauge theories with a Chern-Simons term. Their effective $N=2$ supersymmetry provides an initial fixed point where the Bogomolny bound is saturated on the world-sheet, corresponding to an extreme Reissner-Nordstrom solution in space-time. Away from the singularity the gauge theory has world-sheet matter fields, bosons and fermions, associated with the generation of target space-time. Because the fermions are complex (cf the Quantum Hall Effect) rather than real (cf high-$T_c$ superconductors) the energetically-preferred vacuum is not parity or time-reversal invariant, and the associated renormalization group flow explains the cosmological arrow of time, as well as the decay of real or virtual black holes, with a monotonic increase in entropy.

description: Apotheker Anton Ducke (1807–1888) war ein vielseitig interessierter oberschwäbischer Naturforscher des 19. Jahrhunderts. Heute ist sein Namen fast völlig vergessen. Aus Anlass seines 200. Geburtstags wird an Leben und Werk dieses in seiner Zeit bekannten und geschätzten Mannes erinnert. Als Botaniker sind ihm in Oberschwaben zahlreiche Erstnachweise für Württemberg gelungen, dies sowohl bei Blütenpflanzen als auch bei Moosen. Der Geologe Ducke hat sich besonders für die erratischen Blöcke interessiert. Er war der erste, der ihre alpine Herkunft systematisch erforscht und ihren Transport durch den Rheintalgletscher richtig gedeutet hat. Damit war er seiner Zeit über 20 Jahre voraus, stand dafür aber eben so lang im Gegensatz zur gängigen Lehrmeinung. Als Wasseranalytiker hat er Quellwasser sowohl für die Trink- und Brauchwasserversorgung als auch für Heil- und Reinigungsbäder untersucht. Duckes Aktivitäten werden beschrieben und vor dem zeitgeschichtlichen Hintergrund dargestellt.

description: The Debye-Waller factor has been calculated for stabilized delta-phase plutonium with 5% aluminum. A quasi-harmonic Born-von Karman force model with temperature dependent phonon frequencies was used to calculate the mean-square thermal atomic displacement from absolute zero to 800 K. Implementation of the observed anomalous softening of the long wavelength phonons with increasing temperature cannot account for the softening of the measured thermal parameter at high temperatures nor for its rather high value at low temperatures. The implications for diffraction measurements on delta-phase stabilized plutonium alloys are discussed.

description: Voronoi and Delaunay (Delone) cells of the root and weight lattices of the Coxeter-Weyl groups W(an) and W(dn) are constructed. The face centered cubic (fcc) and body centered cubic (bcc)lattices are obtained in this context. Basic definitions are introduced such as parallelotope, fundamental simplex, contact polytope, root polytope, Voronoi cell, Delone cell, n-simplex, n-octahedron (cross polytope), n-cube and n-hemicube and their volumes are calculated. Voronoi cell of the root lattice is constructed as the dual of the root polytope which turns out to be the union of Delone cells. It is shown that the Delone cells centered at the origin of the root lattice An are the polytopes of the fundamental weights w1, w2, ..., wn and the Delone cells of the root lattice Dn are the polytopes obtained from the weights w1, wn-1, wn. A simple mechanism explains the tessellation of the root lattice by Delone cells. We prove that the (n-1)-facet of the Voronoi cell of the root lattice An is (n-1)-dimensional rhombohedron and similarly the (n-1) -facet of the Voronoi cell of the root lattice Dn is a dipyramid with a base of (n-2)-cube. Volume of the Voronoi cell is calculated via its (n-1) -facet which in turn can be obtained from the fundamental simplex. Tessellations of the root lattice with the Voronoi and Delone cells are explained by giving examples from lower dimensions. Similar considerations are also worked out for the weight lattices An* and Dn*.

description: Privacy-preserving smart meter control strategies proposed in the literature so far make some ideal assumptions such as instantaneous control without delay, lossless energy storage systems etc. In this paper, we present a one-step-ahead predictive control strategy using Bayesian risk to measure and control privacy leakage with an energy storage system. The controller estimates energy state using a three-circuit energy storage model to account for steady-state energy losses. With numerical experiments, the controller is evaluated with real household consumption data using a state-of-the-art adversarial algorithm. Results show that the state estimation of the energy storage system significantly affects the controller's performance. The results also show that the privacy leakage can be effectively reduced using an energy storage system but at the expense of energy loss.

Data-Driven Statistical Models of Robotic Manipulation

Publisher: name: Carnegie Mellon University
Year: 2018
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: Improving robotic manipulation is critical for robots to be actively useful in realworld factories and homes. While some success has been shown in simulation and controlled environments, robots are slow, clumsy, and not general or robust enough when interacting with their environment. By contrast, humans effortlessly manipulate objects. One possible reason for this discrepancy is that, starting from birth, humans have years of experience to collect data and develop good internal models of what happens when they manipulate objects. If robots could also learn models from a large amount of real data, perhaps they, too, could become more capable manipulators. In this thesis, we propose to improve robotic manipulation by solving two problems. First, we look at how robots can collect a large amount of manipulation data without human intervention. Second, we study how to build statistical models of robotic manipulation from the collected data. These data-driven models can then be used for planning more robust manipulation actions. To solve the first problem of enabling large data collection, we perform several different robotic manipulation experiments and use these as case studies. We study bin-picking, post-grasp manipulation, pushing, tray tilting, planar grasping, and regrasping. These case studies allow us to gain insights on how robots can collect a large amount of accurate data with minimal human intervention. To solve the second problem of statistically modeling manipulation actions, we propose models for different parts of various manipulation actions. First, we look at how to model post-grasp manipulation actions by modeling the probability distribution of where an object ends up in a robot’s hand, and how this affects its success rate at various tasks such as placing or insertion. Second, we model how robots can change the pose of an object in their hand with regrasp actions. Third, we improve on the place and pick regrasp action by modeling each separately with more data. These learned data-driven models can then be used for planning more robust and accurate manipulation actions.

description: This work explores different mechanisms that induce thermal rectification in the nanoscale. The presence of interacting energy channels combined with simple asymmetries is sufficient for promoting the desired behavior. We use simple quantum dot configurations, identifying the basic properties that enhance rectification for each case: the size of a quantum dot state space (which suggests the use of scaled up systems with many interacting channels), tunneling asymmetries due to coherent tunneling in a double quantum dot, or quantum interference in a triangular triple quantum dot. An efficient and tunable thermal diode is proposed using a channel capacitively coupled to a mesoscopic switch.

Größtenteils handelte es sich um weit verbreitete Arten, die einen nährsalzreichen Boden anzeigen. Mehrere hiervon wiesen außerdem eine gewisse Resistenz gegen Herbizide auf. Daneben zeigten sich vereinzelt Pflanzen, die von Ruderalstandorten bekannt sind. Diese manchmal in Südwestdeutschland nur selten auftretenden Arten profitieren von der Möglichkeit, sich auf den Feldern mit Körnermais bis Mitte oder sogar Ende Oktober entwickeln zu können. Ein begrenzter Herbizideinsatz im Randbereich würde deshalb die Maisäcker mit mehr pflanzlichem und tierischem Leben bereichern.

description: In decays of the $Z^0$, the dominant mechanism for the direct production of charmonium states is the decay of the $Z^0$ into a charm quark or antiquark followed by its fragmentation into the charmonium state. We calculate the fragmentation functions describing the splitting of charm quarks into S-wave charmonium states to leading order in the QCD coupling constant. Leading logarithms of $M_Z/m_c$ are summed up using Altarelli-Parisi evolution equations. Our analytic result agrees with the complete leading order calculation of the rate for $Z^0 \rightarrow ψc {\bar c}$. We also use our fragmentation functions to calculate the production rate of heavy quarkonium states in $W^\pm$, top quark, and Higgs decays.

description: The capacity to listen gives a profoundly integrating character to human relating and coexistence. It holds distinct importance within the psychotherapeutic context since therapists’ foremost activity is aimed at attuning to clients’ meanings of experience. Across the psychotherapeutic literature, listening transpires to be the most effective agent for client change and the heart of the therapeutic relationship. However, research on the listening experience per se is scarce, and existing perspectives on listening tend to primarily convey practitioners’ as opposed to clients’ stance and observations. In response to this, the current study explores clients’ experience of ‘being listened to’ in the psychotherapeutic context. Interpretative Phenomenological Analysis of textual data generated via semi-structured interviews with six women in recent or current psychotherapy identified two master themes: ‘Being listened to’: no place to hide and Cues to self: the phenomenology of ‘being listened to’. The themes capture collectively shared, distinct aspects of the listening phenomenon as it unfolds in the intersubjective client-therapist space. Importantly, clients’ experience of ‘being listened to’ emerges to be a spiralling accumulation of a set of end-products of various combinations between certain key conditions: successful negotiation of deliberate-existential vulnerability; matched client-therapist readiness; sense of connectedness and feeling held; embodied awareness; and experiencing recognition. Through listening, the therapeutic encounter facilitates for clients a transformational experience of ‘being listened to’ potentially leading to a state of ‘no place to hide’ and contributing to the establishment of a distinct experience of self with existential and social legitimacy. The ‘gaze of the other’ (here, the therapist) is re-emphasised as unavoidable and fundamental for accomplishing this transformational potentiality of the ‘being listened to’ spiral. The findings’ implications for practice, training and theory development as well as the study’s strengths and limitations, and ideas for future research are addressed.
Wigner process tomography: Visualization of spin propagators and their spinor properties

description: We study the tomography of propagators for spin systems in the context of finite-dimensional Wigner representations, which completely characterize and visualize operators using shapes assembled from linear combinations of spherical harmonics. The Wigner representation of a propagator can be experimentally recovered by measuring expectation values of rotated axial spherical tensor operators in an augmented system with an additional ancilla qubit. The methodology is experimentally demonstrated for standard one-qubit quantum gates using nuclear magnetic resonance spectroscopy. In particular, this approach provides a direct and compelling visualization of the spinor property of the propagators corresponding to the rotation of a spin 1/2 particle.

Anatomische und molekulargenetische Untersuchungen an Schachtelhalmen (Equisetum)
Creators: name: Brune, Thomas

description: Das weltweite Vorkommen der Schachtelhalme (Equisetopsida) wird durch nur 15 rezente Arten in der einzigen Gattung Equisetum repräsentiert. Die sichere Ansprache der einzelnen Taxa ist allerdings wegen hoher Variabilität sowie dem Auftreten von Kreuzungen erschwert: Insgesamt sind bisher 18 Hybrid-Kombinationen bekannt. Als Differenzierungsmöglichkeiten werden mit der vorliegenden Arbeit Charakteristika des Spross-Querschnitts überprüft und die Anwendbarkeit von ‚ISSR-PCR‘-Mustern als zusätzlicher Merkmalskomplex evaluiert. Es werden die mitteleuropäischen Arten sowie schwerpunktmäßig verschiedene Populationen von vier in Südwestdeutschland vorkommenden Kreuzungen angesprochen. Die Spross-Querschnitts-Merkmale, z. B. die Ausbildung des Festigungsgewebes, des Assimilationsparenchyms, der Interzellulargänge und der Zentralhöhle, variierten in Abhängigkeit der Sprosshöhe, insbesondere in der Untergattung Hippochaete. Als intermediär in einigen Charakteristika erwiesen sich die Kreuzungen E. × litorale und E. × trachyodon. Uneinheitlich dagegen neigten die Sprosse von E. × moorei (= E. hyemale × E. ramosissimum) mehr E. ramosissimum zu oder waren von E. hyemale kaum zu unterscheiden. E. ramosissimum zeigte extreme Variabilität. E. × meridionale ähnelte stark der Elternart E. variegatum. Insgesamt erwies sich der Spross-Querschnitt zur Differenzierung der Taxa aus der Untergattung Hippochaete als von untergeordneter Bedeutung, jedoch als sehr hilfreich im Falle des Subgenus Equisetum. Die erzeugten ISSR-Bandenmuster waren in jedem Fall hoch charakteristisch für die jeweilige Art. Aus der Position hybridogener Taxa in der Cluster-Analyse lässt sich der Kreuzungscharakter bestätigen und die Elternarten können benannt werden. Das Verwenden unterschiedlicher ISSR-Primer entspricht dabei im Prinzip verschiedenen Blickrichtungen auf das Genom und führt damit jeweils zur Wiedergabe anderer Charakteristika der verschiedenen Kreuzungen. So war beispielsweise E. × litorale (= E. arvense × E. fluviatile) je nach verwendetem Primer entweder mehr der einen Elternart – E. arvense – oder mehr der anderen – E. fluviatile – zugeordnet. Die genetischen Ähnlichkeiten – basierend auf Ähnlichkeiten der Bandenmuster – deuten zudem daraufhin, dass manche Arten offenbar vegetative Reproduktion bevorzugen (z. B. E. arvense), während bei anderen Spezies sexuelle Reproduktion häufiger vorzukommen scheint (z. B. E. sylvaticum).

description: Data-driven modeling is essential to understanding complex cellular processes. In this thesis, we present a series of studies of analyzing morphological dynamics and intracellular transport of organelles using techniques of mathematical modeling, image processing and machine learning. We first characterized the morphology of organelles, focusing specifically on mitochondria. We developed a morphological data processing pipeline. Using this pipeline, we discovered a bi-modal distribution of mitochondrial sizes, with a stable mean value in each mode. We then developed a data-driven model to investigate how fusion / fission of mitochondria modulates their sizes. For further analysis of morphology of mitochondria as well as other cellular components, we developed a general purpose machine learning algorithm, which we refer to as shape component analysis (SCA). We used it for dimension reduction and classification of mitochondrial morphology and protein geometry. In addition to studying the morphological dynamics of cellular organelles using data-driven modeling, we investigated the intracellular transport of organelles. We first proposed a probabilistic model for studying the relation between mitochondrial size and the velocity of their active transport. The proposed model not only explained the relation between mitochondrial size and velocity observed in experiments under normal conditions but also suggested a novel relation under changed conditions. Further analysis of the proposed model also suggested a way to evaluate the binding/unbinding rates of motors carrying the mitochondria. We further studied the global organization of organelle transport. We proposed an image processing framework to characterize the spatiotemporal dynamics of intracellular transport in terms of the spatial localization of stationary organelles and the spatiotemporal patterns of organelle movement, respectively. We used this framework to analyze time-lapse images of Lamp1 transport and found different global transport patterns. Overall, our studies produced both computational modeling methods and specific biological results for quantitative and systems-level understanding the complex behavior of intracellular organelles.

Longleaf: a repository-independent utility for applying digital preservation processes to files

description: Our institution has developed longleaf, a new portable, command-line, repository-agnostic, rules-based tool for monitoring, replicating, and applying preservation processes to files. As our digital collections infrastructure has grown over the past 20 years, we've found it difficult to apply digital preservation plans consistently across system-defined content boundaries. We chose to develop longleaf in order to address several ongoing technological preservation challenges that we feel are also common at other institutions, including the uneven application of preservation practices across systems and rising computational cost as collections grow. We argue that the complexity of digital preservation technologies and the manner in which they are coupled with repository management systems contribute significantly to these problems. Longleaf reduces the interference of repository system constraints in what should be a needs-based digital preservation planning process by applying preservation processes at the file and storage level rather than through a repository system intermediary. Files managed in temporary storage or non-preservation asset management systems can now benefit from the same replication and verification processes as those ingested into preservation repositories.
