description: We use micro-focus Brillouin light scattering spectroscopy to study the effects of spin-orbit torque on thermal spin waves in almost angular-momentum compensated ferrimagnetic CoGd alloy films. The spin-orbit torque is produced by the electric current flowing in the Pt layer adjacent to CoGd. Both the ferromagnetic and the exchange modes are detected in our measurements. The intensity and the linewidth of the ferromagnetic mode are modified by the spin-orbit torque. In contrast, the properties of the exchange mode are unaffected by the spin-orbit torque. We also find that the frequencies and the linewidths of both modes are significantly modified by Joule heating, due to the strong temperature dependence of the magnetic properties of CoGd in the vicinity of angular momentum compensation point. Our results provide insight into the mechanisms that can enable the implementation of sub-THz magnetic nano-oscillators based on ferrimagnetic materials, as well as related effects in antiferromagnets.

description: Glycans associated with biopharmaceutical drugs play crucial roles in drug safety and efficacy, and therefore, their reliable detection and quantification is essential. Our study introduces a multi-level quantification approach for glycosylation analysis in monoclonal antibodies, focusing on minor abundant glycovariants. Mass spectrometric data is evaluated mainly employing open-source software tools. Released glycan and glycopeptide data form the basis for integrating information across different molecular and structural levels up to intact glycoproteins. A comprehensive site-specific comparison showed that indeed, variations across structural levels were observed especially for minor abundant species. Utilizing MoFi, a tool for annotating mass peaks of intact proteins, we quantify isobaric glycosylation variants at the intact protein level. Our workflow's utility is demonstrated on NISTmAb, rituximab and adalimumab, profiling their minor abundant variants for the first time across diverse structural levels. This study enhances understanding and accessibility in glycosylation analysis, emphasizing the significance of minor abundant glycovariants in therapeutic antibodies.

description: In these lectures, we review the main properties of the topological theory obtained by twisting the N=2 two-dimensional superconformal algebra, associated to supersymmetric string compactifications. In particular, we describe a set of physical quantities in string theory that are computed by topological amplitudes. These are in general higher-dimensional F-terms in the low energy effective supergravity, or fermion masses after supersymmetry breaking. We discuss N=2 compactifications of type II strings, N=1 compactifications of heterotic and type I strings, as well as N=4 string vacua. Particular emphasis is put on alternative string dual representations allowing calculability, and on the generalization of N=2 holomorphicity and its anomaly.

description: Fingerprint distances, which measure the similarity of atomic environments, are commonly calculated from atomic environment fingerprint vectors. In this work we present the simplex method which can perform the inverse operation, i.e. calculating fingerprint vectors from fingerprint distances. The fingerprint vectors found in this way point to the corners of a simplex. For a large data set of fingerprints, we can find a particular largest volume simplex, whose dimension gives the effective dimension of the fingerprint vector space. We show that the corners of this simplex correspond to landmark environments that can by used in a fully automatic way to analyse structures. In this way we can for instance detect atoms in grain boundaries or on edges of carbon flakes without any human input about the expected environment. By projecting fingerprints on the largest volume simplex we can also obtain fingerprint vectors that are considerably shorter than the original ones but whose information content is not significantly reduced.

Zoller, Nature 414, 413 (2001)], but which uses photon pair sources in combination with memories that allow to store a large number of temporal modes. We suggest to realize such multi-mode memories based on the principle of photon echo, using solids doped with rare-earth ions. The use of multi-mode memories promises a speedup in entanglement generation by several orders of magnitude and a significant reduction in stability requirements compared to the DLCZ protocol.

description: Improving a Rule-based Fraud Detection System with Classification Based on Association Rule MiningThe detection of fraudulent insurance claims is a great challenge for insurance companies. Although the detection possibilities are getting better and better, fraudsters do not hesitate also using newer and more sophisticated methods. Apart from establishing new fraud detection systems, also the existing systems need to be updated and improved as best as possible. One common detection system is a rule-based expert system that checks predefined rules and gives alerts when certain conditions are met. Usually, the rules are treated separately and correlations within the rules are considered insufficiently. The work at hand describes how the classification based on association rule mining is used for improving such rule-based systems by bringing in relations between pairs of rules. The rule weights are determined through a genetic optimizer.

description: The recently discovered colliding-wind binary (CWB) Apep has been shown to emit luminously from radio to X-rays, with the emission driven by a binary composed of two Wolf-Rayet (WR) stars of one carbon-sequence (WC8) and one nitrogen-sequence (WN4-6b). Mid-infrared imaging revealed a giant spiral dust plume that is reminiscent of a pinwheel nebula but with additional features that suggest Apep is a unique system. We have conducted observations with the Australian Long Baseline Array to resolve Apep's radio emission on milliarcsecond scales, allowing us to relate the geometry of the wind-collision region to that of the spiral plume. The observed radio emission shows a bow-shaped structure, confirming its origin as a wind-collision region. The shape and orientation of this region is consistent with being originated by the two stars and with being likely dominated by the stronger wind of the WN4-6b star. This shape allowed us to provide a rough estimation of the opening angle of $\sim 150^\circ$ assuming ideal conditions. The orientation and opening angle of the emission also confirms it as the basis for the spiral dust plume. We also provide estimations for the two stars in the system to milliarcsecond precision. The observed radio emission, one order of magnitude brighter and more luminous than any other known non-thermal radio-emitting CWB, confirms it is produced by an extremely powerful wind collision. Such a powerful wind-collision region is consistent with Apep being a binary composed of two WR stars, so far the first unambiguously confirmed system of its kind.

title: Modified pigments and mechanisms of energy transfer in LH2 complexes from purple bacteria
Creators: name: Fraser, Niall Johnston
Publisher: name: University of Glasgow
Year: 1998

description: The energy transfer processes in the LH2 complex from Rps. acidophila 10050 were investigated using a pigment-exchange strategy. In this approach, the Bchla-B800 molecules were selectively removed from their binding pockets and were replaced with modified pigments with altered spectral properties. Spectroscopic analysis of these modified complexes gave valuable insights into the mechanisms of energy transfer within the complex. The Bchla-B800 molecules can be released from their binding pockets by an acid treatment using buffer containing the novel Triton detergent TBGIO. B850-only complexes can then be purified by ion-exchange chromatography. Later, the empty B800 sites can be reconstituted with native Bchk. Maximal occupancy of the B800 sites can be obtained by incubating the B850-only complexes in buffer solution containing the detergent dodecyl-p-D- maltoside (LM) with a 3x fold excess of Bchla for 2 h at pH 8 and at room temperature. The Bchk-B800 reconstituted complex was fully characterised to determine how similar it is to native LH2. The average occupancy of the B800 sites in the Bchk-B800 reconstituted complex is ~ 80%. Resonance Raman spectroscopy showed that the reconstituted pigments are correctly bound within the complex and, as judged by CD spectroscopy, the structure of the LH complex is not affected by the pigment-exchange process. In addition, the reconstituted molecules participate in efficient B800?B850 energy transfer. Abstract The pigment-exchange protocol was then used with a series of modified pigments. The B800 binding sites can be reconstitued with geranylgeraniol Bchla, 132OH Bchla, Zn-Bphe, 31vinyl Bchla, 31OH Bchla, acetyl Chla and Chla. The B800 pockets can not be reconstituted with either pyro-Bchla, Cu- Bphe or Ni-Bphe. The 31vinyl Bchla-, 31OH Bchla-, acetyl Chla- and Chla- B800 reconstituted complexes are of particular interest as they have strongly blue-shifted "B800" Qy absorptions with maxima at 765, 751, 693 and 669 nm. CD spectroscopy again showed that the reconstituted pigments are correctly bound within the respective complexes. The occupancies of the B800 sites in the 31vinyl Bchla-, 31OH Bchla-, acetyl Chla- and Chla-B800 reconstituted complexes have yet to be accurately determined. In all of the reconstituted complexes, those pigment molecules which are correctly bound within the B800 binding pockets participate in efficient B800?B850 energy transfer. The kinetics of B800?B850 energy transfer in native and selected reconstituted complexes were studied by fs transient absorption spectroscopy. In both the native and Bchla-B800 reconstituted complexes, B800?B850 energy transfer takes approximately 0.9 ps. The time constants for B800?B850 energy transfer in the 3Vinyl Bchla-, 31OH Bchla-, acetyl Chla- and Chla-B800 reconstituted complexes are 1.4, 1.8, 4.4 and 8.5 ps respectively. This shows that the rate of B800-.

Dabei gibt es wahrscheinlich keine unschädliche Dosis: weniger ist immer besser. Diese Arbeit zeigt, dass luftqualitätsgewichtete Fahrradrouten die persönliche Exposition gemäß dem Regressionsmodell deutlich reduzieren können, wobei die errechneten Umwege zumeist nur minimal sind. Auf Basis offener Daten wird ein neuronales Netzwerk zur Schätzung der Luftqualität trainiert. Dabei werden PM10-Daten aus mobilen Messungen als Indikator der Luftqualität verwendet. Das entstehende Land-Use-Regression-Modell bezieht dabei sowohl zeitliche als auch räumliche Features mit ein. Anschließend wird dieses Modell verwendet, um luftqualitätsgewichtete Routen zu berechnen. Dabei wird gezeigt, wie ein solches feingranulare Modell im Routing verwendet werden kann. Anhand von zufällig gewählten Start/Ziel Paaren werden die luftqualitätsgewichteten Routen mit der jeweils kürzesten Strecke verglichen.
The Minimum Description Length Principle and Model Selection in Spectropolarimetry
Creators: name: Ramos, A. Asensio
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: It is shown that the two-part Minimum Description Length Principle can be used to discriminate among different models that can explain a given observed dataset. The description length is chosen to be the sum of the lengths of the message needed to encode the model plus the message needed to encode the data when the model is applied to the dataset. It is verified that the proposed principle can efficiently distinguish the model that correctly fits the observations while avoiding over-fitting. The capabilities of this criterion are shown in two simple problems for the analysis of observed spectropolarimetric signals. The first is the de-noising of observations with the aid of the PCA technique. The second is the selection of the optimal number of parameters in LTE inversions. We propose this criterion as a quantitative approach for distinguising the most plausible model among a set of proposed models. This quantity is very easy to implement as an additional output on the existing inversion codes.

description: Chatbots have the potential to significantly increase the efficiency of banks and public institutions. Both sectors, however, are subject to special regulations and restrictions in areas such as information security and data protection. The policies of these organizations therefore, in some cases, reject the use of cloud and proprietary products because in their view they lack transparency. As a result, the implementation of chatbots in banks and public institutions often focuses on open-source and on-premises solutions; however, there are hardly any scientific guidelines on how to implement these systems. Our paper aims to close this research gap. The article proposes a reference architecture for chatbots in banks and public institutions that are a.) based on open-source software and b.) are hosted on-premises. The framework is validated by case studies at TeamBank AG and the German Federal Employment Agency. Even if our architecture is designed for these specific industries, it may also add value in other sectors – as chatbots are expected to become increasingly important for the practical application of artificial intelligence in enterprises.
The Geometry of PSR B0031-07

description: PSR B0031-07 is well known to exhibit three different modes of drifting sub-pulses (mode A, B and C). It has recently been shown that in a multifrequency observation, consisting of 2700 pulses, all driftmodes were visible at low frequencies, while at 4.85 GHz only mode-A drift or non-drifting emission was detected. This suggests that modes A and B are emitted in sub-beams, rotating at a fixed distance from the magnetic axis, with the mode-B sub-beams being closer to the magnetic axis than the mode-A sub-beams. Diffuse emission between the sub-beams can account for the non-drifting emission. Using the results of an analysis of simultaneous multifrequency observations of PSR B0031-07, we set out to construct a geometrical model that includes emission from both sub-beams and diffuse emission and describes the regions of the radio emission of PSR B0031-07 at each emission frequency for driftmodes A and B. Based on the vertical spacing between driftbands, we have determined the driftmode of each sequence of drift. To restrict the model, we calculated average polarisation and intensity characteristics for each driftmode and at each frequency. The model reproduces the observed polarisation and intensity characteristics, suggesting that diffuse emission plays an important role in the emission properties of PSR B0031-07. The model further suggests that the emission heights of this pulsar range from a few kilometers to a little over 10 kilometers above the pulsar surface. We also find that the relationships between height and frequency of emission that follow from curvature radiation and from plasma-frequency emission could not be used to reproduce the observed frequency dependence of the width of the average intensity profiles.

The combination approximation method
Creators: name: Fang, Yuan
Publisher: name: The Australian National University
Year: 2018

description: The purpose of this thesis is to introduce the combination approximation method for the second order elliptic boundary-value problems under certain conditions. This method is developed based on the combination technique and the two-scale finite element discretization scheme. The combination approximation method has improved parallel scalabilities with a bounded resultant sacrifice of accuracy, thus strengthening the potential of grid-based methods in high-dimensional settings. Compare to the combination technique, it also has the flexibility in choosing which parts of the domain are to be partitioned into finer grids and which parts into coarser grids to suit different needs for discretizations.
Surface Defect, Anomalies and $b$-Extremization

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

description: Quantum field theories (QFT) in the presence of defects exhibit new types of anomalies which play an important role in constraining the defect dynamics and defect renormalization group (RG) flows. Here we study surface defects and their anomalies in conformal field theories (CFT) of general spacetime dimensions. When the defect is conformal, it is characterized by a conformal $b$-anomaly analogous to the $c$-anomaly of 2d CFTs. The $b$-theorem states that $b$ must monotonically decrease under defect RG flows and was proven by coupling to a spurious defect dilaton. We revisit the proof by deriving explicitly the dilaton effective action for defect RG flow in the free scalar theory. For conformal surface defects preserving ${\cal N}=(0,2)$ supersymmetry, we prove a universal relation between the $b$-anomaly and the 't Hooft anomaly for the $U(1)_r$ symmetry. We also establish the $b$-extremization principle that identifies the superconformal $U(1)_r$ symmetry from ${\cal N}=(0,2)$ preserving RG flows. Together they provide a powerful tool to extract the $b$-anomaly of strongly coupled surface defects. To illustrate our method, we determine the $b$-anomalies for a number of surface defects in 3d, 4d and 6d SCFTs. We also comment on manifestations of these defect conformal and 't Hooft anomalies in defect correlation functions.

description: We show that the valley Chern number of the low energy band in twisted double bilayer graphene can be tuned through two successive topological transitions, where the direct bandgap closes, by changing the electric field perpendicular to the plane of the graphene layers. The two transitions with Chern number changes of -3 and +1 can be explained by the formation of three satellite Dirac points around the central Dirac cone in the moiré Brillouin zone due to the presence of trigonal warping. The satellite cones have opposite chirality to the central Dirac cone. Considering the overlap of the bands in energy, which lead to metallic states, we construct the experimentally observable phase diagram of the system in terms of the indirect bandgap and the anomalous valley Hall conductivity. We show that while most of the intermediate phase becomes metallic, there is a narrow parameter regime where the transition through three insulating phases with different quantized valley Hall conductivity can be seen. We systematically study the effects of variations in the model parameters on the phase diagram of the system to reveal the importance of particle-hole asymmetry and trigonal warping in constructing the phase diagram. We also study the effect of changes in interlayer tunneling on this phase diagram.
Lifestyle perspectives of persons with disabilities in a person-centered support paradigm
Creators: name: Malette, Paul Hector
Publisher: name: University of British Columbia
Year: 2009

description: This study is a qualitative investigation of a person-centered support option called micro boards. A micro board is a small non profit society comprised of family and friends who assist persons with disabilities to develop individualized housing and support options. Defining features of the micro board project include direct funding to individuals with disabilities to secure housing and support options, freedom to choose where and with whom to live, and autonomy in hiring and defining the nature of personal care and support. Three persons with severe disabilities were the primary focus of this study. These individuals required extensive supports in all aspects of daily living including feeding, dressing, and mobility. They resided in three separate subsidized or cooperative living arrangements in a large urban centre in the Province of British Columbia. Two organizations central to the micro board project were also a focus of study. The study period was eighteen months. Qualitative techniques were employed to collect and analyze data regarding lifestyle quality in the micro board project, and organizational assumptions and characteristics inherent in this support paradigm. Results indicated that all three participants with disabilities experienced positive lifestyle gains as a result of the micro board project. Direct funding and the freedom to choose accommodation and individualized support structures were identified as axial to lifestyle quality. Participants also experienced increased community participation and expanding networks of social support as a result of the micro board project. An analysis of the characteristics and themes embedded in the multiple case studies identified five responsive organizational characteristics which contributed to the development of the micro board project, and assisted in the achievement of a quality life in the community for the three participants in this study: willingness to change; inclusion of persons with disabilities and their families in organizational policy; small, flexible support structures; collaborative planning; and a holistic view of support grounded in social justice. These results are discussed in relation to previous research done in this area. Inferences are made about how factors such as lifestyle planning, empowerment, personal perceptions of disability, and responsive support systems influenced lifestyle quality. Parallels are drawn to related health care fields, and a restructuring of disability support is explored. Limitations of the research are identified, and potential areas for further research are suggested.

description: By contrast to design meetings, design evaluation meetings (DEMs) have generally been considered as situations in which, according to DEMs methodologies, design activities are quite marginal. In a study of DEMs in software development, i.e. in technical review meetings following a particular review methodology, we showed: (i) the occurrence of design activities as part of an argumentation process; (ii) the relative importance of cognitive synchronisation as a prerequisite for evaluation; (iii) the important role played in evaluation by argumentation that makes explicit the underlying design rationale (DR). On the basis of our results, we discuss the potential for using DR methodologies in this kind of meetings.

description: The random walk of magnetic field lines is an important ingredient in understanding how the connectivity of the magnetic field affects the spatial transport and diffusion of charged particles. As solar energetic particles (SEPs) propagate away from near-solar sources, they interact with the fluctuating magnetic field, which modifies their distributions. We develop a formalism in which the differential equation describing the field line random walk contains both effects due to localized magnetic displacements and a non-stochastic contribution from the large-scale expansion. We use this formalism together with a global magnetohydrodynamic simulation of the inner-heliospheric solar wind, which includes a turbulence transport model, to estimate the diffusive spreading of magnetic field lines that originate in different regions of the solar atmosphere. We first use this model to quantify field line spreading at 1 au, starting from a localized solar source region, and find rms angular spreads of about 20° - 60°. In the second instance, we use the model to estimate the size of the source regions from which field lines observed at 1 au may have originated, thus quantifying the uncertainty in calculations of magnetic connectivity; the angular uncertainty is estimated to be about 20°. Finally, we estimate the filamentation distance, i.e., the heliocentric distance up to which field lines originating in magnetic islands can remain strongly trapped in filamentary structures. We emphasize the key role of slab-like fluctuations in the transition from filamentary to more diffusive transport at greater heliocentric distances.
The strange-sea quark spin distribution in the nucleon from inclusive and semi-inclusive deep-inelastic scattering

description: We propose new method which allows determination of the strange-sea quark spin distribution in the nucleon through measurement of various inclusive and semi-inclusive polarized deep inelastic electron- or muon-proton reactions. It is shown, that using combinations of inclusive data and semi-inclusive data containing neutral pions in the final state, it is possible to extract the strange-sea quark spin distribution. Similar result can be obtained for charged pions and some other hadrons also.

description: Computational modelling is an indispensable tool to study the dynamics of biological systems. A stochastic model is considered to be more promising in the modelling of the biological system as this approach explicitly acknowledges the resultant uncertainties in biochemical processes. In this thesis, the chemical master equation (CME) is used to provide the stochastic description of the chemically reacting systems. However, the CME is difficult to solve as the computational complexity grows exponentially with the number of chemical species. In this regard, the system partitioning approach can be used to reduce the model dimension if the chemically reacting systems possess multiscale dynamics nature. The study in this thesis mainly focuses on the chemically reacting systems which display multiple time scales and their CMEs. The singular perturbation theory is used in conjunction with the technique of aggregation and disaggregation or the method of finite state projection for model reduction. In particular, a systematic analysis, which is based on the theory of singular perturbation and the technique of aggregation and disaggregation, is applied to the general solution of the CME. Consequently several reduced CMEs and some approximate solutions to the CME are derived with guaranteed error bounds and reduced computational costs. Furthermore, a systemic concept of the finite state projection is used in conjunction with singular perturbation theory to reduce the size of the state space of the system, that is, the concept of paths and state transition probabilities are introduced and are used to discard some unlikely states from the full state space. We illustrate the efficiency of these approaches in several examples and the corresponding numerical results indicate that the computational costs of these approaches are significantly reduced.

Determinism, Noise, and Spurious Estimations in a Generalised Model of Population Growth

description: We study a generalised model of population growth in which the state variable is population growth rate instead of population size. Stochastic parametric perturbations, modelling phenotypic variability, lead to a Langevin system with two sources of multiplicative noise. The stationary probability distributions have two characteristic power-law scales. Numerical simulations show that noise suppresses the explosion of the growth rate which occurs in the deterministic counterpart. Instead, in different parameter regimes populations will grow with ``anomalous'' stochastic rates and (i) stabilise at ``random carrying capacities'', or (ii) go extinct in random times. Using logistic fits to reconstruct the simulated data, we find that even highly significant estimations do not recover or reflect information about the deterministic part of the process. Therefore, the logistic interpretation is not biologically meaningful. These results have implications for distinct model-aided calculations in biological situations because these kinds of estimations could lead to spurious conclusions.

Molecular absorptions in high-z objects

description: Molecular absorption lines measured along the line of sight of distant quasars are important probes of the gas evolution in galaxies as a function of redshift. A review is made of the handful of molecular absorbing systems studied so far, with the present sensitivity of mm instruments. They produce information on the chemistry of the ISM at z \sim 1, the physical state of the gas, in terms of clumpiness, density and temperature. The CMB temperature can be derived as a function of z, and also any possible variations of fundamental constants can be constrained. With the sensitivity of ALMA, many more absorbing systems can be studied, for which some predictions and perspectives are described.

Exact and quasi-resonances in discrete water-wave turbulence

description: The structure of discrete resonances in water-wave turbulence is studied. It is shown that the number of exact 4-wave resonances is huge (hundreds million) even in comparatively small spectral domain when both scale and angle energy transport is taken into account. It is also shown that angle transport can contribute inexplicitly to scale transport. Restrictions for quasi-resonances to start are written out. The general approach can be applied directly to mesoscopic systems encountered in condensed matter (quantum dots), medical physics, etc.

Magnetorotational-type instability in Couette-Taylor flow of a viscoelastic polymer liquid

Subjects: subject: Astrophysics (astro-ph)

description: We describe an instability of viscoelastic Couette-Taylor flow that is directly analogous to the magnetorotational instability (MRI) in astrophysical magnetohydrodynamics, with polymer molecules playing the role of magnetic field lines. By determining the conditions required for the onset of instability and the properties of the preferred modes, we distinguish it from the centrifugal and elastic instabilities studied previously. Experimental demonstration and investigation should be much easier for the viscoelastic instability than for the MRI in a liquid metal. The analogy holds with the case of a predominantly toroidal magnetic field such as is expected in an accretion disk and it may be possible to access a turbulent regime in which many modes are unstable.
