description: We attempt to give a gentle (though ahistorical) introduction to Koszul duality phenomena for the Hecke category, focusing on the form of this duality studied in joint work of Achar, Riche, Williamson, and the author. We illustrate some key phenomena and constructions for the simplest nontrivial case of (finite) $\mathrm{SL}_2$ using Soergel bimodules, a concrete algebraic model of the Hecke category.

description: A new 8-dim conformal gauging solves the auxiliary field problem and eliminates unphysical size change from Weyl's electromagnetic theory. We derive the Maurer-Cartan structure equations and find the zero curvature solutions for the conformal connection. By showing that every one-particle Hamiltonian generates the structure equations we establish a correspondence between phase space and the 8-dim base space, and between the action and the integral of the Weyl vector. Applying the correspondence to generic flat solutions yields the Lorentz force law, the form and gauge dependence of the electromagnetic vector potential and minimal coupling. The dynamics found for these flat solutions applies locally in generic spaces. We then provide necessary and sufficient curvature constraints for general curved 8-dimensional geometries to be in 1-1 correspondence with 4-dimensional Einstein-Maxwell spacetimes, based on a vector space isomorphism between the extra four dimensions and the Riemannian tangent space. Despite part of the Weyl vector serving as the electromagnetic vector potential, the entire class of geometries has vanishing dilation, thereby providing a consistent unified geometric theory of gravitation and electromagnetism. In concluding, we discuss the observability of the extra dimensions.

description: We consider a mirror world scenario, in which light Dirac neutrinos are generated from a seesaw mechanism and leptogenesis occurs at high scale without violating lepton number. After leptogenesis, the conservation laws of the theory imply the visible baryon-minus-lepton asymmetry to be equal to the mirror baryon-minus-lepton asymmetry. We extend previous work by presenting a detailed study of this Dirac leptogenesis mechanism by constructing the full set of Boltzmann Equations for both cases of unflavored and flavored regimes. We show that $Z_2$ breaking and lepton/mirror lepton flavor effects can be exploited to enhance the final baryon-minus-lepton asymmetry in our world by several orders of magnitude.

description: A strong argument can be made that physics is, at its core, the study of symmetries. Nonlinear optics is certainly no exception, with an enormous number of distinct processes each depending in its own way on the underlying symmetries of the physical system, the light, or of nature itself. Restricting ourselves to optical harmonic generation, we will explore three unique physical systems as well as three symmetries. In each case, the controlled breaking of that symmetry will lead to optical enhancements, novel nonlinearities, or deep physical insights. Beginning with silicon metasurfaces, we will explore the effects of even and odd spatial symmetries in optical systems. The periodic breaking of this symmetry will lead us to the highly engineerable physics of bound states in the continuum. By studying the harmonic emission from an atomic gas in the volume surrounding the metasurface, we will come to understand that significant nonlinear optical enhancements can be engineered with any linewidth and at any wavelength. In the context of the two-dimensional material hexagonal boron nitride, we will investigate and break crystal inversion symmetries. Using an intense laser tuned to the phonon resonance of hexagonal boron nitride, large amplitude anharmonic ionic motions will provide us a powerful degree of control over the internal symmetries of the system at an atomic level. Breaking this symmetry, we measure short-lived even-order nonlinearities that would otherwise be forbidden in equilibrium. Our observations for second- and third- harmonic generation are confirmed by time-dependent density functional theory. Those simulations further extend the understanding of this symmetry-breaking effect to even higher order processes. Lastly, single-crystal graphene and graphite provide an ideal platform through which to explore time-reversal symmetry. Chiral photons, or optical beams with ellipticity and handedness, are well known to break time-reversal symmetry. While applying high-power, chiral light to graphene, the breaking of time-reversal lifts a degeneracy of the K and K’ valleys in the momentum space Brillouin zone. Lifting this degeneracy, we unveil underlying spatial symmetry properties of graphene in odd-order third- and fifth- harmonic generation which should otherwise be unobservable. We also show experimentally, for the first time, that valley polarization and population can be extracted using our technique.
Symmetry Breaking and the Inverse Energy Cascade in a Plasma

description: The application of electrostatic bias to both low density plasma with coherent fluctuations and high density plasma with turbulent fluctuations confined by a magnetic dipole are investigated. Previously, electrostatic biasing of low density plasma was symmetric, drove rapid plasma rotation, and excited the centrifugal interchange instability. This research investigates the application of non-symmetric bias and the influence of broken symmetry on strongly turbulent plasmas. Non- symmetric bias is applied through either point biasing or an equatorial array spanning the device. In both cases, the spatial symmetry of applied bias dramatically effects the plasma fluctuations. With bias applied, the plasma achieves a new equilibrium characterized by amplified low order modes and diminished amplitude of higher order modes. Although the turbulent spectrum changes, the RMS fluctuation level is unchanged by the bias. Bias also causes the turbulent electrostatic fluctuations to coalesce into a quasi-coherent mode and the appearance of increased coherence. The effect of bias configuration is also seen to change the measured levels of nonlinear coupling. Non-symmetric biasing increases nonlinear coupling while symmetric biasing leaves the coupling unchanged. These results represent the first experimental demonstration of symmetry breaking driving the inverse energy cascade in a quasi-two dimensional plasma system. The application of dynamic and rotating electrostatic bias as well as plans for applying turbulent feedback are discussed.

description: Numerous multi-objective evolutionary algorithms have been designed for constrained optimisation over past two decades. The idea behind these algorithms is to transform constrained optimisation problems into multi-objective optimisation problems without any constraint, and then solve them. In this paper, we propose a new multi-objective method for constrained optimisation, which works by converting a constrained optimisation problem into a problem with helper and equivalent objectives. An equivalent objective means that its optimal solution set is the same as that to the constrained problem but a helper objective does not. Then this multi-objective optimisation problem is decomposed into a group of sub-problems using the weighted sum approach. Weights are dynamically adjusted so that each subproblem eventually tends to a problem with an equivalent objective. We theoretically analyse the computation time of the helper and equivalent objective method on a hard problem called ``wide gap''. In a ``wide gap'' problem, an algorithm needs exponential time to cross between two fitness levels (a wide gap). We prove that using helper and equivalent objectives can shorten the time of crossing the ``wide gap''. We conduct a case study for validating our method. An algorithm with helper and equivalent objectives is implemented. Experimental results show that its overall performance is ranked first when compared with other eight state-of-art evolutionary algorithms on IEEE CEC2017 benchmarks in constrained optimisation.

description: We propose a quantum algorithm for projecting a quantum system to eigenstates of any Hermitian operator, provided one can access the associated control-unitary evolution for the ancilla and the system, as well as the measurement of the controlling ancillary qubit. Such a Hadamard-test like primitive is iterated so as to achieve the spectral projection, and the distribution of the projected eigenstates obeys the Born rule. This algorithm can be used as a subroutine in the quantum annealing procedure by measurement to drive the system to the ground state of a final Hamiltonian, and we simulate this for quantum many-body spin chains.

We identify it with a Slodowy slice in the nilpotent cone of the symplectic Lie algebra of rank $r$. Hence it possesses a symplectic resolution with $2r$ fixed points with respect to a Hamiltonian torus action. We also idenfity its flavor deformation with a base change of the full Slodowy slice.

description: Low-temperature specific heat (SH) is measured for the 12442-type KCa$_2$Fe$_4$As$_4$F$_2$ single crystal under different magnetic fields. A clear SH jump with the height of $ΔC/T|_{T_c}$ = 130 mJ/mol K$^2$ is observed at the superconducting transition temperature $T_c$. It is found that the electronic SH coefficient $Δγ(H)$ quickly increases when the field is in the low-field region below 3 T and then considerably slows down the increase with a further increase in the field, which indicates a rather strong anisotropy or multi-gap feature with a small minimum in the superconducting gap(s). The temperature-dependent SH data indicates the presence of the $T^2$ term, which supplies further information and supports the picture with a line-nodal gap structure. Moreover, the onset point of the SH transition remains almost unchanged under the field as high as 9 T, which is similar to that observed in cuprates, and placed this system in the middle between the BCS limit and the Bose-Einstein condensation.

description: An analytical prediction is established of how an isolated many-body quantum system relaxes towards its thermal long-time limit under the action of a time-independent perturbation, but still remaining sufficiently close to a reference case whose temporal relaxation is known. This is achieved within the conceptual framework of a typicality approach by showing and exploiting that the time-dependent expectation values behave very similarly for most members of a suitably chosen ensemble of perturbations. The predictions are validated by comparison with various numerical and experimental results from the literature.

description: The computation of the entire Lyapunov spectrum for extended dynamical systems is a very time consuming task. If the system is in a chaotic spatio-temporal regime it is possible to approximately reconstruct the Lyapunov spectrum from the spectrum of a sub-system in a very cost effective way. In this work we present a new rescaling method, which gives a significantly better fit to the original Lyapunov spectrum. It is inspired by the stability analysis of the homogeneous evolution in a one-dimensional coupled map lattice but appears to be equally valid in a much wider range of cases. We evaluate the performance of our rescaling method by comparing it to the conventional rescaling (dividing by the relative sub-system volume) for one and two-dimensional lattices in spatio-temporal chaotic regimes. In doing so we notice that the Lyapunov spectra for consecutive sub-system sizes are interleaved and we discuss the possible ways in which this may arise. Finally, we use the new rescaling to approximate quantities derived from the Lyapunov spectrum (largest Lyapunov exponent, Lyapunov dimension and Kolmogorov-Sinai entropy) finding better convergence as the sub-system size is increased than with conventional rescaling.

description: Judgments of symmetry lay at the heart of the classical theory of probability. It was by direct appeal to the symmetries exhibited by the processes underlying simple games of chance that the earliest theorists of probability were able to justify the initial assumptions of equiprobability which allowed them to compute the probabilities of more complex events using combinatorial methods, i.e., by simply counting cases. Nevertheless, in spite of the role that symmetry played in the earliest writings on the subject, in light of the fact it is only in highly contrived settings that a direct appeal to symmetries can suffice to determine the probabilities of events, many philosophers have been led to conclude that the concept of symmetry itself has, at best, a limited role to play in a general theory of probability. In this essay, I argue that this view of the matter is mistaken, and that judgments of symmetry, in fact, have an indispensible role to play in all probabilistic reasoning. In chapter 1, I provide a detailed account of symmetry-based reasoning and argue against the view that the judgments of relevance on which such reasoning is based must be construed in subjective terms if symmetry-based reasoning is to be applied to deterministic processes. In chapter 2, I argue that the two most plausible proposals for how to avoid an appeal to symmetry in the assignment of probabilities (viz., those which are based on a priori principles of epistemic conservatism or the observed frequencies of events) must themselves rely on implicit assumptions of symmetry if they are to defend themselves against the charges of incoherency and arbitrariness. In chapter 3, I consider a decision-theoretic example of symmetry-based reasoning, in which the appeal to symmetry arises in the context of an agent's choice of a deliberative methodology. In this context, the principle of symmetry amounts to the requirement that the agent avoid adopting a biased deliberative methodology, i.e., one which treats two equally legitimate sources of information differently. In the specific context of the exchange paradox, I propose an account of how biased information is to be handled, which, despite suffering from some important defects, does, I believe, capture some of our general intuitions about how a rational agent ought to adjust his expectations to correct for the effects of bias.

description: Spiking Neural Networks (SNNs) have recently emerged as a prominent neural computing paradigm. However, the typical shallow SNN architectures have limited capacity for expressing complex representations while training deep SNNs using input spikes has not been successful so far. Diverse methods have been proposed to get around this issue such as converting off-the-shelf trained deep Artificial Neural Networks (ANNs) to SNNs. However, the ANN-SNN conversion scheme fails to capture the temporal dynamics of a spiking system. On the other hand, it is still a difficult problem to directly train deep SNNs using input spike events due to the discontinuous, non-differentiable nature of the spike generation function. To overcome this problem, we propose an approximate derivative method that accounts for the leaky behavior of LIF neurons. This method enables training deep convolutional SNNs directly (with input spike events) using spike-based backpropagation. Our experiments show the effectiveness of the proposed spike-based learning on deep networks (VGG and Residual architectures) by achieving the best classification accuracies in MNIST, SVHN and CIFAR-10 datasets compared to other SNNs trained with a spike-based learning. Moreover, we analyze sparse event-based computations to demonstrate the efficacy of the proposed SNN training method for inference operation in the spiking domain.

description: The measurement of peak and remoulded shear strength, and the post-peak reduction in strength with strain, of contractive tailings is undergoing increased focus based on recent prominent tailings storage facility (TSF) failures and subsequent industry guidance. One tool that offers benefits in this area is the vane shear test (VST) as it measures shear strengths directly in situ in a relatively undisturbed state and can directly measure aspects of post peak softening to larger strains than most common laboratory tests. However, for the data from a VST to be useful, it must be unambiguously measuring undrained shear strengths without appreciable drainage occurring during the test. Despite this clear necessity, as most VST standards are focused on predominately low permeability clay soils, arguably insufficient attention and details related to drainage issues is included in the currently available standards – particularly post-peak, where significant time may be required to reach a remoulded strength, increasing the risk of partial drainage. This issue is exacerbated by a lack of consensus as to which analytical framework is most suitable to quantify the potential onset and magnitude of drainage. To provide additional data to assist in the quantification of drainage during the VST, and to highlight the issue generally, this paper presents the results of a series of VST carried out in a predominately siltsized iron ore tailings. The consolidation characteristics of the material are such that use of “standard” VST rotation rates appeared likely to result in pre-failure drainage affecting strengths recorded by the VST. As such, a range of rotation rates and methods were applied to investigate the onset of drainage, with particular focus on post-peak conditions. The data suggests that drainage may be inhibiting the observation of strain softening of the tailings. The two available methods to infer drainage acting on a VST agree reasonably with the results of the data presented here.

description: Development of the sympathetic nervous system (SNS) tone onto peripheral organs has been shown to be susceptible to a wide range of external factors, such as temperature. Although it was initially postulated that the sympathetic signal is uniform across the body, there is growing evidence that there can be target-specific sympathetic signals. To date, evidence for a relationship between developmental influences on SNS tone and organ function is purely correlational. An obstacle to investigating the programming of SNS permanently altering physiology is that experimental manipulations of SNS activity during development would impact multiple organ functions simultaneously, which could affect the overall health of the animal and therefore confound interpretation of the results. Here we used brown adipose tissue (BAT) as a platform to define a critical period and identify molecules that contribute to the development of SNS outflow to peripheral organs. In addition, we explored the molecular target-specificity of sympathetic neurons by performing a single-cell RNA sequencing transcriptomic analysis of adult mouse stellate ganglion (SG) in conjunction with retrograde tracing from two of its targets, brown adipose tissue and forelimb. We discovered four molecularly distinct populations of SG neurons that express unique combinations of neuropeptides and receptors, but we did not find evidence of target specificity. The four distinct SG neuronal populations had marker genes that showed unique expression in each population, including genes encoding secreted peptides and receptors of circulating factors. Also, we found that the expression of some of the marker genes differs across the sympathetic chain, which could provide a means for coordinated regulation of SNS responses to specific types of homeostatic challenges.

description: The impact of the use of a large number of new industry inspired teaching laboratories was investigated over three years. This was achieved through surveys and focus groups and predominately investigated the shift in student perceptions over this time period. It was found that the new experiences aided the students with regards to their ability to articulate their developed skills. Other shifts were noted with students becoming more aware of the connection between laboratories and the real-world, but this was lost over time due to the larger number of traditional experiences in the final year of their undergraduate experience.

Die Hauptprobleme der Produktion sind der hohe spezifische Leistungseintrag, der durch die hohe Viskosität des Mediums bedingt ist, und die großen Penicillinverluste bei der Aufarbeitung der Fermentationsbrühe. die durch die geringe Stabilität des Penicillins bei den geringen pH-Werten der Extraktion bedingt sind.
Man benötigte in der Industrie 4-5 kW/m^3, um in das hoch viskose Medium ausreichenden Sauerstoff einzutragen.
Bei der Aufarbeitung betrugen die Verluste etwa 15%.
Die Zielsetzung der Arbeit war, den spezifischen Leistungseintrag und die Verluste zu reduzieren.
Symphonic Culture in Paris, 1880-1900: The Bande à Franck and Beyond

description: Parisian musical life underwent a tectonic shift in the late nineteenth century. Throughout the 1800s, and particularly during the Second Empire (1852-70), opera and other forms of theatrical entertainment had dominated the French musical scene. In the final decades of the century, however, a generation of French composers devoted considerable efforts to large-scale symphonic forms. A driving force in the advancement of orchestral music was the "Franck circle" or bande à  Franck--a group of more-or-less young composers mentored by an unassuming organ professor at the Paris Conservatoire. In their symphonic works, these musicians challenged the longstanding Austro-German dominance of serious instrumental genres and cultivated a distinctly French musical voice. This dissertation explores the burgeoning symphonic culture of Paris circa 1880-1900 by examining four representative compositions by prominent members of the Franck circle: Augusta Holmès's Les Argonautes (1880), Ernest Chausson's Viviane (1882-83, revised 1887), César Franck's Psyché (1886-87), and Vincent d'Indy's Istar (1896). Each of these pieces, the subject of an individual chapter, offers a study in the relationship between compositional practice and cultural identity. The critical success of Les Argonautes catapulted Holmès to national prominence and established her reputation as one of the most progressive composers in France. Chausson's extensive revisions to Viviane, his first major orchestral work, reveal his evolving attitudes about descriptive music and Wagner--the composer who cast the longest shadow in fin-de-siècle France. Although Franck based Psyché on a legend from Greek antiquity, his approach to musical signification allowed his disciples to interpret the piece variously as a Christian allegory or as absolute music. D'Indy's polemical stances on genre, artistic influence, and morality belie the ideological complexities and paradoxes in his Istar. In addition to illuminating these works through reception history, musical analysis, manuscript studies, and the composers' own writings, the dissertation will address three interrelated topics in each chapter. First, I explore how the bande à  Franck understood the concept of "serious" music, and how this conception shaped Third Republic attitudes about orchestral genres, absolute music, and program music. Second, I examine how French composers responded to the legacy of Wagner in non-theatrical genres. Finally, I discuss how these four musicians fashioned a cultural, national, and personal identity through--and sometimes in tension with--their orchestral works.

The convergence of these approximations in the sense of weak convergence of measures is proven. We describe a family of sets of unparametrized paths that are analogous to cylinder sets of parametrized paths. Integrals over some of these sets are evaluated in terms of Dirichlet propagators in bounded regions.

description: We give a short introduction to cough detection efforts that were undertaken during the last decade and we describe the solution for automatic cough detection developed for the AioCare portable spirometry system. In contrast to more popular analysis of sound and audio recordings, we fully based our approach on airflow signals only. As the system is intended to be used in a large variety of environments and different patients, we trained and validated the algorithm using AioCare-collected data and the large database of spirometry curves from the NHANES database by the American National Center for Health Statistics. We trained different classifiers, such as logistic regression, feed-forward artificial neural network, support vector machine, and random forest to choose the one with the best performance. The ANN solution was selected as the final classifier. The classification results on the test set (AioCare data) are: 0.86 (sensitivity), 0.91 (specificity), 0.91 (accuracy) and 0.88 (F1 score). The classification methodology developed in this study is robust for detecting cough events during spirometry measurements. As far as we know, the solution presented in this work is the first fully reproducible description of the automatic cough detection algorithm based totally on airflow signals and the first cough detection implemented in a commercial spirometry system that is to be published.

The power of surrogate data testing with respect to non-stationarity
Creators: name: Timmer, J.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: Surrogate data testing is a method frequently applied to evaluate the results of nonlinear time series analysis. Since the null hypothesis tested against is a linear, gaussian, stationary stochastic process a positive outcome may not only result from an underlying nonlinear or even chaotic system, but also from e.g. a non-stationary linear one. We investigate the power of the test against non-stationarity.

description: Donna Haraway’s Chthulucene suggests a world in which humans and non-humans are inextricably entangled, a world in which global ecological devastation demands new ways of relating across disciplines and across differences, a world in which strategic coalitions across disciplines—fluid transdisciplinary coalitions—are badly needed. Haraway suggests sympoiesis, or making-with, as a move toward response-ability. In this project, I embrace the rich fabric of Narrative Inquiry in English Education and knit a diffractive, transdisciplinary reading of current debates in reading/literacy studies, composing speculative fiction as I compose my own approaches to teaching and research and figure a sympoietic pedagogy.

Symptom Networks of Common Mental Disorders in an Adult Primary Care Sample in India

Anxiety disorders

description: The common mental disorders (CMDs) which include non-psychotic depression and anxiety-related disorders aggregate mental illnesses commonly seen together without assuming clear diagnostic boundaries. Thus, it provides an excellent platform for a symptom-level investigation of common suffering in regions where the current Western-based diagnostic categories may not apply. This current study investigates the symptom networks of CMDs among adult primary care patients in India, using data from a clinical trial testing the effectiveness of a collaborative stepped-care intervention led by lay health counselors. Network modeling was used to investigate a) symptom centralities, b) boundaries between depression and anxiety-related disorders, and c) baseline differences in network configurations across gender, public versus private health care settings, and treatment response over one-year of follow-up. Intense anxiety/panic and fatigue were the most central symptoms overall. While panic and depressed mood were the most central in public health care settings, fatigue and depressed mood were most central in private settings. Overall, findings indicate central symptoms might differ across cultures and socioeconomic groups. To the knowledge of this current author, this is the first study investigating the symptom networks of CMDs among primary care patients in India.

A new class of accelerated regularization methods, with application to bioluminescence tomography
Creators: name: Gong, Rongfang
name: Hofmann, B.

Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this paper we propose a new class of iterative regularization methods for solving ill-posed linear operator equations. The prototype of these iterative regularization methods is in the form of second order evolution equation with a linear vanishing damping term, which can be viewed not only as an extension of the asymptotical regularization, but also as a continuous analog of the Nesterov's acceleration scheme. New iterative regularization methods are derived from this continuous model in combination with damped symplectic numerical schemes. The regularization property as well as convergence rates and acceleration effects under the Hölder-type source conditions of both continuous and discretized methods are proven. The second part of this paper is concerned with the application of the newly developed accelerated iterative regularization methods to the diffusion-based bioluminescence tomography, which is modeled as an inverse source problem in elliptic partial differential equations with both Dirichlet and Neumann boundary data. A relaxed mathematical formulation is proposed so that the discrepancy principle can be applied to the iterative scheme without the usage of Sobolev embedding constants. Several numerical examples, as well as a comparison with the state-of-the-art methods, are given to show the accuracy and the acceleration effect of the new methods.
A low energy optimization of the CERN-NGS neutrino beam for a theta_{13} driven neutrino oscillation search
Creators: name: Rubbia, A.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The possibility to improve the CERN to Gran Sasso neutrino beam performances for theta_{13} searches is investigated. We show that by an appropriate optimization of the target and focusing optics of the present CNGS design, we can increase the flux of low energy neutrinos by about a factor 5 compared to the current tau optimized focalisation. With the ICARUS 2.35 kton detector at LNGS and in case of negative result, this would allow to improve the limit to sin^22 theta_{13} by an order of magnitude better than the current limit of CHOOZ at Delta m^2 approximately 3 times 10^{-3} eV^2 within 5 years of nominal CNGS running. This is by far the most sensitive setup of the currently approved long-baseline experiments and is competitive with the proposed JHF superbeam.
