description: We reconsider the proposal of excited dark matter (DM) as an explanation for excess 511 keV gamma rays from positrons in the galactic center. We quantitatively compute the cross section for DM annihilation to nearby excited states, mediated by exchange of a new light gauge boson with off-diagonal couplings to the DM states. In models where both excited states must be heavy enough to decay into e^+ e^- and the ground state, the predicted rate of positron production is never large enough to agree with observations, unless one makes extreme assumptions about the local circular velocity in the Milky Way, or alternatively if there exists a metastable population of DM states which can be excited through a mass gap of less than 650 keV, before decaying into electrons and positrons.

Adaptive Model-Based Visual Stabilization of Image Sequences Using Feedback
Creators: name: Bogatyrenko, Evgeniya
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2011

description: Visual stabilization proposed in this paper compensates changes of the scene caused by motion and deformation of an observed object. This is of high importance in computer-assisted beating heart surgery, where the views of the beating heart should be stabilized. The proposed model-based method defines visual stabilization as a transformation of the current image sequence to a stabilized image sequence. This transformation incorporates physical model of the observed object and model of the measurement process. In contrast to standard approaches, the quality of the visual stabilization is continuously evaluated and improved in two aspects. On the one hand, discretization errors are reduced. On the other hand, the parameters of the underlying models are adjusted. The performance of the proposed method is evaluated in an experiment with a pressure-regulated artificial heart. Compared with standard methods, the model-based method provides higher accuracy, which is additionally improved by a feedback mechanism.
Globally hyperbolic geodesically complete cosmological model

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this talk we shall show a perfect fluid cosmological model and its properties. The model possesses an orthogonally transitive abelian two-dimensional group of isometries that corresponds to cylindrical symmetry. The matter content is a stiff fluid that satisfies the energy and generic conditions. The metric is not separable in comoving coordinates for the fluid. The curvature invariants are shown to be regular everywhere in the coordinate chart and also indicate that the spacetime is asymptotically flat. Furthermore the causal geodesics are studied in order to determine that they are complete and that the model is globally hyperbolic. The model goes through an initial contracting epoch that is followed by an expanding era.

description: Quantum discord quantifies non-classical correlations in a quantum system including those not captured by entanglement. Thus, only states with zero discord exhibit strictly classical correlations. We prove that these states are negligible in the whole Hilbert space: typically a state picked out at random has positive discord; and, given a state with zero discord, a generic arbitrarily small perturbation drives it to a positive-discord state. These results hold for any Hilbert-space dimension, and have direct implications on quantum computation and on the foundations of the theory of open systems. In addition, we provide a simple necessary criterion for zero quantum discord. Finally, we show that, for almost all positive-discord states, an arbitrary Markovian evolution cannot lead to a sudden, permanent vanishing of discord.

description: This is the third part in a series of guidebooks focused on understand and applying the CSCCE Community Participation Model. In this section, we focus on the role of scaffolding to support and grow inclusive communities in STEM. In part one of the CSCCE Community Participation Model (CPM) guidebook, we outlined our model for describing member engagement in STEM communities - the domain on which CSCCE focuses. And in part two, we focused on the role of community champions, emergent leaders who take on additional roles within the community to ensure its maintenance, growth, and evolution. About CSCCE The Center for Scientific Collaboration and Community Engagement (CSCCE) champions the importance of human infrastructure for effective collaboration in STEM. We provide training and support for the people who make scientific collaborations succeed at scale - and we also research the impact of these emerging roles.

Form factor expansions in the 2D Ising model and Painlevé VI

description: We derive a Toda-type recurrence relation, in both high and low temperature regimes, for the $λ$ - extended diagonal correlation functions $C(N,N;λ)$ of the two-dimensional Ising model, using an earlier connection between diagonal form factor expansions and tau-functions within Painlevé VI (PVI) theory, originally discovered by Jimbo and Miwa. This greatly simplifies the calculation of the diagonal correlation functions, particularly their $λ$-extended counterparts. We also conjecture a closed form expression for the simplest off-diagonal case $C^{\pm}(0,1;λ)$ where a connection to PVI theory is not known. Combined with the results for diagonal correlations these give all the initial conditions required for the $ł$-extended version of quadratic difference equations for the correlation functions discovered by McCoy, Perk and Wu. The results obtained here should provide a further potential algorithmic improvement in the $ł$-extended case, and facilitate other developments.

description: Word document. Recognizing the importance of visual inspection in the maintenance of the civil air fleet, the FAA tasked the Aging Aircraft Nondestructive Inspection Validation Center (AANC) at Sandia National Labs in Albuquerque, NM, to establish a visual inspection reliability program. This report presents the results of the first phase of that program, a benchmark visual inspection reliability experiment. The benchmark experiment had 12 airline inspectors perform specific inspection tasks on AANC's Boeing 737 in order to estimate overall performance characteristics of a typical set of inspectors on a typical set visual inspection tasks. The report also includes a separate but related probability of detection study on small but visible cracks at rivet locations on fabricated fuselage skin splices. Conclusions are drawn with respect to quantification of inspection reliability, search and decision aspects of visual inspection, use of job cards during inspection, and inspector specific factors affecting visual inspection performance.

description: We report results of a new global next-to-leading order fit of parton distribution functions in which cuts on W and Q are relaxed, thereby including more data at high values of x. Effects of target mass corrections (TMCs), higher twist contributions, and nuclear corrections for deuterium data are significant in the large-x region. The leading twist parton distributions are found to be stable to TMC model variations as long as higher twist contributions are also included. The behavior of the d quark as x-->1 is particularly sensitive to the deuterium corrections, and using realistic nuclear smearing models the d-quark distribution at large x is found to be softer than in previous fits performed with more restrictive cuts.

description: In this short review, I draw attention to new developments in the theory of fault tolerance in quantum computation that may give concrete direction to future work in the development of superconducting qubit systems. The basics of quantum error correction codes, which I will briefly review, have not significantly changed since their introduction fifteen years ago. But an interesting picture has emerged of an efficient use of these codes that may put fault tolerant operation within reach. It is now understood that two dimensional surface codes, close relatives of the original toric code of Kitaev, can be adapted to effectively perform logical gate operations in a very simple planar architecture, with error thresholds for fault tolerant operation simulated to be 0.75%. This architecture uses topological ideas in its functioning, but it is not 'topological quantum computation' -- there are no non-abelian anyons in sight. I offer some speculations on the crucial pieces of superconducting hardware that could be demonstrated in the next couple of years that would be clear stepping stones towards this surface-code architecture.

Study of a perturbation in a glow discharge
Creators: name: Baldis, Hector Alberto
Publisher: name: University of British Columbia
Year: 2012

description: The perturbation in a glow discharge in hydrogen is studied theoretically and experimentally. In an ordinary glow discharge a perturbation has been produced by applying a small sinusoidal high frequency electric field. This modulates the electron energy and hence the number density of atoms in excited states; The relative phase and amplitude of light emitted in the first four lines of the Balmer series have been measured. A theory based on the work of Bates et al, is developed in this thesis and the results predicted give better agreement with the experimental values than do alternative theories which have been published recently. These if absorption of line radiation by the discharge is shown to have a critical effect on the behaviour of the plasma. The limitations and validity of assumptions are discussed and a modified experiment is suggested.
Ritualising encounters with subterranean places: an investigation of urban depositional practices of Roman Britain
Creators: name: Collie, N
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates the depositional practices of the towns of Roman Britain. The material remains of these depositional events are characterised by the appearance of certain objects and bodies within particular subterranean features. The most common types of objects and bodies found within urban centres include complete and almost complete pottery vessels, dogs and other domestic species, infants and sometimes metal objects and personal objects. The most common feature types are shafts, pits and wells with some evidence for deposits made underneath buildings or other structures. This investigation was motivated by the suggestion that urban depositional practices may have been distinct in form and function from those found in other location types such as rural areas. Furthermore, previous research into the subterranean deposits of Dorchester and Silchester has proposed diverse cultural origins for these practices. Although suggestions have been made regarding the nature of urban depositional practices in Roman Britain, systematic analysis of a large body of data from urban locations has not previously been undertaken. Analysis of a large number of subterranean features and their contents from urban sites was compared to analyses of subterranean features from three other location types: non-urban sites, sacred precinct sites and Roman military forts. An emerging pattern of difference between the characteristics of urban deposits and those found in other locations was further tested via close analysis of the three main case studies of Silchester (Calleva Atrebatum), Dorchester (Durnovaria) and Verulamium. It was found that there was a particular set of characteristics that were common to urban depositional practices of Roman Britain. There were also distinctive changes to all of the case studies' depositional practices during the third century AD. Furthermore, the close analysis of the three case studies also revealed that there were inter-urban differences in depositional practices, particularly in terms of spatial distribution of these features. These differences were then read for variations in processes of urbanisation and cultural change over time. Comment is also made on the nature of urbanisation in Roman Britain and how at each site the 'Roman town' was translated in a unique and place-specific manner.

description: We show that open-loop dynamical control techniques may be used to synthesize unitary transformations in open quantum systems in such a way that decoherence is perturbatively compensated for to a desired (in principle arbitrarily high) level of accuracy, which depends only on the strength of the relevant errors and the achievable rate of control modulation. Our constructive and fully analytical solution employs concatenated dynamically corrected gates, and is applicable independently of detailed knowledge of the system-environment interactions and environment dynamics. Explicit implications for boosting quantum gate fidelities in realistic scenarios are addressed.

Sparse Mixture Conditional Density Estimation by Superficial Regularization
Creators: name: Krauthausen, Peter
name: Ruoff, Patrick
name: Hanebeck, Uwe D.
Publisher: name: Karlsruhe
Year: 2011

description: In this paper, the estimation of conditional densities between continuous random variables from noisy samples is considered. The conditional densities are modeled as heteroscedastic Gaussian mixture densities allowing for closed-form solution of Bayesian inference with full-densities. The main contributions of this paper are an improved generalization quality of the estimates by the introduction of a superficial regularizer, the consideration of model uncertainty relative to local data densities by means of adaptive covariances, and the proposition of an efficient distance-based estimation algorithm. This algorithm corresponds to an iterative nested optimization scheme, optimizing hyper-parameters, component placement, and mixture weights. The obtained solutions are sparse, smooth, and generalize well as benchmark experiments, e.g., in nonlinear filtering show.

In a similar way, we also prove sufficient conditions for 1d and 2d localization below the ground state of such an operator. Furthermore, we extend our results to 1d and 2d localization in d dimensions; for example, a linear or planar defect in a 3d crystal. For the case of D-fold degenerate band edges, we also give sufficient conditions for localization of up to D states.

A method for knowledge discovery and development with health data
Creators: name: Ling, Tristan
Publisher: name: University Of Tasmania
Year: 2023

description: One of the most overlooked problems in the field of knowledge discovery is the acquisition and incorporation of existing knowledge about the data being analysed (Fayyad, Piatetsky-Shapiro et al. 1996; Pohle 2003; Kotsifakos, Marketos et al. 2008; Marinica and Guillet 2009). Doing this efficiently and effectively can greatly improve the relevance and usefulness of the results discovered, particularly for complex domains with a large amount of existing knowledge (Adejuwon & Mosavi, 2010; C. Zhang, Yu, & Bell, 2009). This study applies the successful Multiple Classification Ripple Down Rules (MCRDR) knowledge acquisition method to build a knowledge base from a complex dataset of lung function data, and describes a method for utilising the dataset to provide additional knowledge validation. The method acquired knowledge successfully, but indicated that a focus on rule-driven knowledge acquisition may adversely affect the MCRDR process. Knowledge acquisition was performed with multiple domain experts, with separate knowledge bases successfully consolidated using an evidence-based method to quantify differences and resolve conflicts. This knowledge comparison method was also tested as a learning and assessment tool for a small group of medical students, with positive results. In addition, the consolidated expert knowledge base was applied to the analysis of the lung function data, with a set of common data mining techniques, to reproduce and expand on a group of published lung function studies. Results showed that new knowledge could be discovered effectively and efficiently in a complex domain, despite the user having little domain knowledge themselves. Results were supported by recent literature, and include findings that may be of interest in the respiratory field. Notably, newly discovered knowledge is automatically incorporated into the knowledge base, allowing incremental knowledge discovery and easy application of those discoveries.

By utilizing the compactification procedure, we show coincidence between the dimensionally reduced coupling and the R-R coupling to D-branes in type II string theory. We also discuss that a cubic term proportional to six-form field reproduces the quartic mass-deformation term in the world-volume theory of multiple M2-branes.

description: Due to a worldwide increased use of pharmaceuticals and, in particular, antibiotics, a growing number of these substance residues now contaminate natural water resources and drinking supplies. This triggers a considerable demand for low-cost, high-sensitivity methods for monitoring water quality. Since many biological substances exhibit strong and characteristic absorption features at wavelengths shorter than 300 nm, UV spectroscopy presents a suitable approach for the quantitative identification of such water-contaminating species. However, current UV spectroscopic devices often show limited light-matter interaction lengths, demand sophisticated and bulky experimental infrastructure which is not compatible with microfluidics, and leave large fractions of the sample analyte unused. Here, we introduce the concept of UV spectroscopy in liquid-filled anti-resonant hollow core fibers, with large core diameters and lengths of approximately 1 m, as a means to overcome such limitations. This extended light-matter interaction length principally improves the concentration detection limit by two orders of magnitude while using almost the entire sample volume—that is three orders of magnitude smaller compared to cuvette based approaches. By integrating the fibers into an optofluidic chip environment and operating within the lowest experimentally feasible transmission band, concentrations of the application-relevant pharmaceutical substances, sulfamethoxazole (SMX) and sodium salicylate (SS), were detectable down to 0.1 µM (26 ppb) and 0.4 µM (64 ppb), respectively, with the potential to reach significantly lower detection limits for further device integration.

description: The NIR Ca II triplet absorption lines have proven to be an important tool for quantitative spectroscopy of individual red giant branch stars in the Local Group, providing a better understanding of metallicities of stars in the Milky Way and dwarf galaxies and thereby an opportunity to constrain their chemical evolution processes. An interesting puzzle in this field is the significant lack of extremely metal-poor stars, below [Fe/H]=-3, found in classical dwarf galaxies around the Milky Way using this technique. The question arises whether these stars are really absent, or if the empirical Ca II triplet method used to study these systems is biased in the low-metallicity regime. Here we present results of synthetic spectral analysis of the Ca II triplet, that is focused on a better understanding of spectroscopic measurements of low-metallicity giant stars. Our results start to deviate strongly from the widely-used and linear empirical calibrations at [Fe/H]

description: Because of the short duty-cycles and observation-time constraints, studies of bright TeV (E>100 GeV) blazars are mostly restricted to flaring episodes or rather short (days to few weeks) multiwavelength campaigns. At the same time, long-term studies of these objects are essential to gain a more complete understanding of the blazar phenomenon and to constrain theoretical models concerning jet physics. Only unbiased long-term studies are adequate for the determination of flaring state probabilities and for estimating the statistical significance of possible correlations between TeV flaring states and other wavebands or observables, such as neutrino events. Regular observations also provide triggers for multiwavelength ToO observations originating from the TeV waveband. These are particularly needed to identify and study orphan TeV flares, i.e. flares without counterparts in other wavebands. In 2007/8 the MAGIC telescope has monitored three TeV blazars on a regular basis: Mrk 501, Mrk 421, and 1ES 1959+650. We present preliminary results of these observations including the measured light curves and a correlation study for VHE gamma-rays and X-rays and VHE gamma-rays and optical R-band for Mrk 421.

description: Successful optimization of the thermoelectric (TE) performance of materials, described by the figure of merit zT, is a key enabler for its application in energy harvesting or Peltier cooling devices. While the zT value of bulk materials is accessible by a variety of commercial measurement setups, precise determination of the zT value for thin and thick films remains a great challenge. This is particularly relevant for films synthesized by electrochemical deposition, where the TE material is deposited onto an electrically conductive seed layer causing an in-plane short circuit. Therefore, a platform for full in-plane zT characterization of electrochemically deposited TE materials is developed, eliminating the impact of the electrically conducting seed layer. The characterization is done using a suspended TE material within a transport device which was prepared by photolithography in combination with chemical etching steps. An analytical model to determine the thermal conductivity is developed and the results verified using finite element simulations. Taken together, the full in-plane zT characterization provides an inevitable milestone for material optimization under realistic conditions in TE devices. © 2020 The Authors.

description: An exactly solvable model of the sawtooth chain with Ising and Heisenberg bonds and with coupling to lattice distortion for Heisenberg bonds is considered in the magnetic field. Using the direct transfer-matrix formalism an exact description of the thermodynamic functions is obtained. The ground state phase diagrams for all regions of parameters values containing phases corresponding to the magnetization plateaus at $M=0,1/4$ and 1/2 have been obtained. Exact formulas for bond distortions for various ground states are presented. A novel mechanism of magnetization plateau stabilization corresponding to $M=1/4$ state is reported.

description: Effects of dynamical long-range correlations over a fluid cell size scale on a relativistic fluid are discussed. It is shown that such correlations among the fluid elements introduced into hydrodynamical model induce some weak dissipation and viscosity into the fluid. The influence of the long-range correlations on the entropy current is also discussed.

Nuclear magnetic resonance in a thallium single crystal
Creators: name: Schratter, Jacob Jack
Publisher: name: University of British Columbia
Year: 2012

description: Nuclear magnetic resonance studies in single crystals of thallium have been performed for the first time. The resonance frequency, line width and second moment were studied as a function of crystal orientation with respect to the magnetic field. The Knight shift parameters were determined at liquid helium and liquid nitrogen temperatures. The anisotropic Knight shift results were in disagreement with the results obtained on powder specimens by other workers.

Superior Cervical Ganglion Stimulation Results in Potent Cerebral Vasoconstriction in Swine
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2022

description: Introduction— Sympathetic activity from the superior cervical ganglion (SCG) has been shown to cause cerebralhypoperfusion in swine, similar to that seen with clinical cerebral vasospasm. Although the mechanism of suchperfusion deficit has been speculated to be from pathologic cerebral vasoconstriction, the extent of sympatheticcontribution to vasoconstriction has not been well-established.Objective— We aimed to demonstrate that SCG stimulation in swine leads to significant cerebral vasoconstrictionon digital subtraction angiography (DSA). Additionally, we aimed to show that inhibition of SCG can mitigate theeffects of sympathetic-mediated cerebral vasoconstriction.Methods— Five SCGs were surgically identified in Yorkshire swine and were electrically stimulated to achievesympathetic activation. DSA was performed to measure and compare changes in cerebral vessel diameter. SyngoiFlow was also used to quantify changes in contrast flow through the cerebral and neck vessels.Results— SCG stimulation resulted in 35-45% narrowing of the ipsilateral ascending pharyngeal, anterior middlecerebral and anterior cerebral arteries. SCG stimulation also decreased contrast flow through ipsilateral ascendingpharyngeal, internal carotid and anterior cerebral arteries as seen on iFLow. These effects were prevented with priorSCG blockade. Minimal vessel caliber changes were seen in the posterior cerebral, posterior middle cerebral andinternal carotid arteries with SCG stimulation.

description: X-ray variability in Active Galactic Nuclei (AGN) is commonly analysed in terms of the Power Spectral Density (PSD). The break observed in the power spectrum can be interpreted as a characteristic X-ray variability time scale. Here we study variability properties within the framework of clumpy accretion flows, in which shocks between accreting elements account for the UV and X-ray emissions. We derive a characteristic X-ray time scale, $τ_{X}$, and compare it with the measured PSD break time scale, $T_{B}$. A quite good agreement is found in both magnitude and trend. In particular, the model dependence on black hole mass and accretion rate precisely reproduces the empirical relation obtained by McHardy et al. (2006). We suggest a possible physical interpretation of the break time scale and briefly discuss the related aspects of optical/UV variability and correlations between different wavelengths.

description: The beneficial, complementary nature of visual and textual information to convey information is widely known, for example, in entertainment, news, advertisements, science, or education. While the complex interplay of image and text to form semantic meaning has been thoroughly studied in linguistics and communication sciences for several decades, computer vision and multimedia research remained on the surface of the problem more or less. An exception is previous work that introduced the two metrics Cross-Modal Mutual Information and Semantic Correlation in order to model complex image-text relations. In this paper, we motivate the necessity of an additional metric called Status in order to cover complex image-text relations more completely. This set of metrics enables us to derive a novel categorization of eight semantic image-text classes based on three dimensions. In addition, we demonstrate how to automatically gather and augment a dataset for these classes from the Web. Further, we present a deep learning system to automatically predict either of the three metrics, as well as a system to directly predict the eight image-text classes. Experimental results show the feasibility of the approach, whereby the predict-all approach outperforms the cascaded approach of the metric classifiers.
