description: The amplitude for hard exclusive pseudoscalar meson electroproduction off nucleon (nuclear) targets is computed in QCD within the leading $α_s \ln {Q^2/λ_{QCD}^{2}}$ approximation. We show that the distribution of recoil nucleons depends strongly on the angle between the momentum of the recoil nucleon and the polarization vector of the target (or outgoing nucleon). This dependence is especially sensitive to the spin flip skewed parton distribution (SPD) $\widetilde E$. We argue also that the scaling for this spin asymmetry sets in at lower Q^2 than that for the absolute cross section. Basing on the chiral quark-soliton model of the nucleon we estimate quantitatively the spin asymmetry. In the case of pi+ production this asymmetry is dominated at small t by the contribution of the pion pole in the isovector SPD $\widetilde E$ as required by PCAC. In the case of K0 production off a proton we find a large enhancement of the cross section as compared to the case of pi0 production. For the forward production of neutral pseudoscalar mesons off a deuteron target we find the cross section should be zero for the zero deuteron helicity (along the $γ^*D$ direction). We consider also cross sections of quasielastic processes off nuclei including the feasibility to implant K+,rho-mesons into nuclear volume.

Training and evaluating adversarial networks: from kernel discrepancies to applications
Creators: name: Binkowski, Mikolaj
Publisher: name: Imperial College London
Year: 2020

description: Implicit generative modelling has experienced remarkable transformation with the emergence and expansion of Generative Adversarial Networks. This generic framework introduced by Goodfellow et al. [2014] became a leading paradigm in generative modelling of images, and allowed generation of sharp and convincing samples, often hardly distinguishable from the real pictures. On the other hand, this rapid growth created a range of problems, spawning a whole new area of research. Despite the impressive results, the adversarial min-max objective makes GANs notoriously difficult to train and requires various regularisation techniques. On the other hand, applications of GANs to non-visual domains have seen limited success. In this thesis we address problems coming from both of these lines of research. Its first part focuses on the theoretical and empirical aspects of GAN formulations motivated by integral probability metrics. In particular, we study gradient penalty for MMD GANs, which use use Maximum Mean Discrepancy as the training objective, and clarify their relation to Wasserstein and Cramér GANs. The latter, being motivated by the energy distance, approximately matches the MMD with energy kernel, which we include it in the study of kernel choice for MMD GANs. We empirically show that gradient-penalised MMD GANs work well with smaller critic networks, improving the training time over Wasserstein GANs. We also present the properties of gradient estimators used in training of IPM-based GANs. In the second part, we apply GANs to unsupervised image-to-image transfer and text-to-speech audio generation. Although impressive results have already been achieved in the former task, they remain limited to situations where modes of source and target distributions are well-matched. In addition, this area lacks rigorous probabilistic setup as well as clear metrics for evaluation. On the other hand, GANs for audio generation have so far worked only for relatively simple tasks. We address these problems by introducing batch weight for domain transfer and GAN-TTS, the first GAN able to generate high-fidelity speech from text. Both of these models benefit from changes to the discriminator networks: we apply joint discriminator on a product space of two domains to learn unsupervised transfer, and ensemble of random-window discriminators that operate on audio sub-samples of different lengths and frequencies. Finally, we study the issue of GAN evaluation, critically examining the properties of the existing methods and proposing a range of new metrics for all of the aforementioned domains.
Bundle Gerbes Applied to Quantum Field Theory

description: This paper reviews recent work on a new geometric object called a bundle gerbe and discusses some new examples arising in quantum field theory. One application is to an Atiyah-Patodi-Singer index theory construction of the bundle of fermionic Fock spaces parametrized by vector potentials in odd space dimensions and a proof that this leads in a simple manner to the known Schwinger terms (Mickelsson-Faddeev cocycle) for the gauge group action. This gives an explicit computation of the Dixmier-Douady class of the associated bundle gerbe. The method works also in other cases of fermions in external fields (external gravitational field, for example) provided that the APS theorem can be applied; however, we have worked out the details only in the case of vector potentials. Another example, in which the bundle gerbe curvature plays a role, arises from the WZW model on Riemann surfaces. A further example is the `existence of string structures' question. We conclude by showing how global Hamiltonian anomalies fit within this framework.

description: Motivated by the ubiquity of turbulent flows in realistic conditions, effects of turbulent advection on two models of classical non-linear systems are investigated. In particular, we analyze model A (according to the Hohenberg-Halperin classification [1]) of a non-conserved order parameter and a model of the direct bond percolation process. Having two paradigmatic representatives of distinct stochastic dynamics, our aim is to elucidate to what extent velocity fluctuations affect their scaling behavior. The main emphasis is put on an interplay between anisotropy and compressibility of the velocity flow on their respective scaling regimes. Velocity fluctuations are generated by means of the Kraichnan rapid-change model, in which the anisotropy is due to a distinguished spatial direction n and a correlator of the velocity field obeys the Gaussian distribution law with prescribed statistical properties. As the main theoretical tool, the field-theoretic perturbative renormalization group is adopted. Actual calculations are performed in the leading (one-loop) approximation. Having obtained infra-red stable asymptotic regimes, we have found four possible candidates for macroscopically observable behavior for each model. In contrast to the isotropic case, anisotropy brings about enhancement of non-linearities and non-trivial regimes are proved to be more stable.

description: Russia and Iran share a common hostility toward the United States. There have, however, been important differences between Moscow and Tehran — especially over nuclear issues. Relations seemed to improve, though, with Vladimir Putin's October 2007 visit to Tehran and Russia's shipment to Iran of the enriched uranium needed to start up the Bushehr nuclear power plant. Important differences, however, remain between the two countries that serve to limit the extent to which they can cooperate.

description: We discuss renormalization of the non-relativistic three-body problem with short-range forces. The problem becomes non-perturbative at momenta of the order of the inverse of the two-body scattering length, and an infinite number of graphs must be summed. This summation leads to a cutoff dependence that does not appear in any order in perturbation theory. We argue that this cutoff dependence can be absorbed in a single three-body counterterm and compute the running of the three-body force with the cutoff. We comment on relevance of this result for the effective field theory program in nuclear and molecular physics.

description: For the first time, we have a plausible and complete accounting of matter and energy in the Universe. Expressed a fraction of the critical density it goes like this: neutrinos, between 0.3% and 15%; stars, between 0.3% and 0.6%; baryons (total), 5% +/- 0.5%; matter (total), 40% +/- 10%; smooth, dark energy, 80% +/- 20%; totaling to the critical density (within the errors). This accounting is consistent with the inflationary prediction of a flat Universe and defines three dark-matter problems: Where are the dark baryons? What is the nonbaryonic dark matter? What is the nature of the dark energy? The leading candidate for the (optically) dark baryons is diffuse hot gas; the leading candidates for the nonbaryonic dark matter are slowly moving elementary particles left over from the earliest moments (cold dark matter), such as axions or neutralinos; the leading candidates for the dark energy involve fundamental physics and include a cosmological constant (vacuum energy), a rolling scalar field (quintessence), and a network of light, frustrated topological defects.

description: Attitude computation is of vital importance for a variety of applications. Based on the functional iteration of the Rodrigues vector integration equation, the RodFIter method can be advantageously applied to analytically reconstruct the attitude from discrete gyroscope measurements over the time interval of interest. It is promising to produce ultra-accurate attitude reconstruction. However, the RodFIter method imposes high computational load and does not lend itself to onboard implementation. In this paper, a fast approach to significantly reduce RodFIter's computation complexity is presented while maintaining almost the same accuracy of attitude reconstruction. It reformulates the Rodrigues vector iterative integration in terms of the Chebyshev polynomial iteration. Due to the excellent property of Chebyshev polynomials, the fast RodFIter is achieved by means of appropriate truncation of Chebyshev polynomials, with provably guaranteed convergence. Moreover, simulation results validate the speed and accuracy of the proposed method.

Option Generation Under Stress

Publisher: name: University of Leicester
Year: 2024
Subjects: Uncategorized

description: Option generation is often a crucial part of decision making in many circumstances. With good options, good decisions are easier to reach. Stress is also an inescapable aspect of life. Research on how option generation is influenced by stress is limited. Previous research has investigated how choices are evaluated and selected from a given pool of options. However, less is known about the decision-making process when options must be generated by the decision maker; especially under stress. This thesis attempts to map the boundary conditions of an individual’s option generation ability and strategy selection. Six experiments were conducted, in which the complexity of the task and situation were manipulated. More options tended to be generated in the chess problems and AUT, whilst fewer were generated in the TSPs. This suggests that problem complexity can activate different option generation and decision-making strategies. Regardless of task complexity or type of stressor, participants favoured a ‘more is better’ approach where more options lead to better quality decisions. Confidence levels in options seemed to be a factor that influenced whether more options were generated. Where there were lower levels of confidence in initial options, participants continued to generate more options and tended to select a final option of a higher quality than the original. The two stressors influenced the option generation process in different ways. Under time pressure, participants who were not able to adjust to the time limit were unable to shift from their previous options and generated more duplicate ideas. Under socio-evaluative stress, participants felt more challenged, helping them to recognise and select the most appropriate options. The research reported in this thesis demonstrated that moderate levels of stress can affect option generation performance in a range of tasks and settings, including online. It also highlights the importance of understanding the role confidence plays in searching for better options.
title: Witnessing in Mediation: Toward an Aesthetic Ethics of Practice
Creators: name: Cobb, Sarah
Publisher: name: School for Conflict Analysis and Resolution
Year: 2004

description: This paper attempts to provide a normative basis for mediation that will hopefully complicate our ethical understanding of this practice. Specifically, I will elaborate a critique of ‘recognition,’ following Oliver (2000), which will allow me to build on the ‘relational transformation’ ethic at the base of the transformative model of mediation, advanced by Bush and Folger. Drawing on Oliver, I will argue that recognition is a concept, anchored in the Enlightenment, that paradoxically reduces rather than enables us to be present to Others, by requiring their strangeness/difference in order to constitute ourselves as whole. In place of this concept, I will offer the process of ‘witnessing’ as a discursive process whereby we constitute the subjectivity of the other and ourselves in the process. Further, drawing on Foucault (1980) and Jabri (1998), I will argue that the ethics of witnessing is not pragmatic in nature, but rather aesthetic, for it is the aesthetic that allows for the creation of a normative model for assessing narrative practice. Finally, drawing on Appreciative Inquiry and the literature on circular questions, I will provide a description of this aesthetic ethics in terms of practice in discourse, suggesting that the mode of inquiry fostered by the mediator is ethical if/when it destabilizes existing narrative and opens up uncertainty, while, at the same time, inviting elaboration of reversals in narrative trajectories. Ultimately, my aim is to elaborate a normative theory for mediation that is anchored in the practice of witnessing and suggestive of an aesthetic of narrative. While this will not dispel the spectre of the critique that Fiss invoked, it may provide some incantations that can be used to shift the grounds on which the discussion takes place, contributing both to our collective reflection and to our ethics of practice.”

description: Manifest N=2 supersymmetric hypermultiplet mass terms can be introduced in the projective N=2 superspace formalism. In the case of complex hypermultiplets, where the gauge covariantized spinor derivatives have an explicit representation in terms of gauge prepotentials, it is possible to interpret such masses as vacuum expectation values of an Abelian vector multiplet. The duality transformation that relates the N=2 off-shell projective description of the hypermultiplet to the on-shell description involving two N=1 chiral superfields allows us to obtain the massive propagators of the N=1 complex linear fields in the projective hypermultiplet. The N=1 massive propagators of the component superfields in the projective hypermultiplet suggest a possible ansatz for the N=2 massive propagator, which agrees with an explicit calculation in N=2 superspace.

description: Shaders are useful in real time graphics and high performance computing applications as they specify computation to be run in parallel on the GPU. In the community, these shaders are often described in mathematical syntax and translating that math to executable code can be tedious and error prone. We present I ❤️ IQ, a graphing calculator of sorts for signed distance functions (SDFs) and materials that expedites the process of prototyping shaders. It provides a math-like syntax using I ❤️ LA and comes with a built-in raycasting architecture, removing the overhead of translation and implementation details. I ❤️ IQ is designed to be responsive and interactive. The system automatically detects free parameters and lets users tweak them using slider controls, allowing for seamless manipulation of the scene in real time. The code generated by I ❤️ IQ can then be exported to third party programs and used outside of the I IQ environment. The I ❤️ IQ repository can be found at https://github.com/HenroKriel/heartdown.

description: In this paper we develop a method introduced by one of us to study metastable states in spin glasses. We consider a `potential function' defined as the free energy of a system at a given temperature $T$ constrained to have a fixed overlap with a reference configuration of equilibrium at temperature $T'$. We apply the method to the spherical p-spin glass and to some generalization of this model in the range of temperatures between the dynamic and the static transition. The analysis suggests a correspondence among local minima of the potential and metastable states. This correspondence is confirmed studying the relaxation dynamics at temperature $T$ of a system starting from an initial configuration equilibrated at a different temperature $T'$.

description: We report on photometry and imaging of the Jupiter Family Comets 41P/Tuttle-Giacobini-Kresak and 45P/Honda-Mrkos-Pajdusakova with the TRAPPIST-North telescope. We observed 41P on 34 nights from February 16, 2017 to July 27, 2017 pre- and post-perihelion (r$_h$=1.04 au), while we collected data for comet 45P from February 10 to March 30 after perihelion (r$_h$=0.53 au). We computed the production rates of the daughter species OH, NH, CN, C$_3$ and C$_2$ and we measured the dust proxy, Af$ρ$, for both comets. The peak of water production rate of 41P was (3.46$\pm$0.20)$\times$10$^{27}$ molecules/s on April 3, 2017 when the comet was at 1.05 au from the Sun. We have shown that the activity of 41P is decreasing by about 30% to 40% from one apparition to the next. We measured a mean water production rate for 45P of (1.43$\pm$0.62)$\times$10$^{27}$ molecules/s during a month after perihelion. Our results show that these Jupiter Family Comets had low gas and dust activity and no outburst was detected. Relative abundances, expressed as ratios of production rates and Af$ρ$ parameter with respect to OH and to CN, were compared to those measured in other comets. We found that 41P and 45P have a typical composition in term of carbon bearing species. The study of coma features exhibited by the CN gas species allowed the measurement of the rotation period of 41P, showing a surprisingly large increase of the rotation period from (30$\pm$5) hrs at the end of March to (50$\pm$10) hrs at the end of April, 2017 in agreement with recent observations by other teams.

description: Acutely infectious viruses including alphaviruses, Venezuelan equine encephalitis virus (VEEV) is vector transmitted, resulting in increased disease burden in the civilian and military population. Several of these pathogens are highly infectious and transmissible as aerosols, thus posing an increased threat as a potential bioweapon. Studies from GMU-CIDR laboratory and from several others have demonstrated the critical role of the host ubiquitination pathway in the establishment of a productive infection for acutely infectious viral agents. For example, it has been demonstrated that proteasome inhibitor Bortezomib was a broad-spectrum inhibitor of alphaviruses and bunyaviruses. Published studies have demonstrated that many viral proteins including the capsid protein of VEEV, the NS1, 3, and 5 proteins of Dengue Virus, VP35 protein of Ebola virus are ubiquitinated in infected cells. As part of efforts to characterize the host: viral protein interactome of alphaviruses using VEEV, we have identified several proteins involved in the ubiquitin-proteasome pathway as interacting with all the viral nonstructural proteins. These observations and evidence in the scientific literature prompted us to hypothesize that ubiquitin-proteasome inhibitors will constitute an excellent broad-spectrum strategy to address emerging/re-emerging viral challenges. As several viral proteins are known to be ubiquitinated in multiple sites, inhibiting such a broadly critical post-translational modification event is highly unlikely to result in resistant viruses. We examined multiple inhibitors of host signaling pathways using Venezuelan Equine Encephalitis Virus as a prototype pathogen. Of eight inhibitors that were tested for antiviral activities against the TC-83 strain of VEEV in three different cell lines (Vero, HMC3, and SVG-p12), NSC697923, Bardoxolone methyl (BARM), Omavelexelone (OMA) demonstrated robust inhibition of TC-83 at 1μM concentration. In vitro dosing studies conducted thus far have quantified viral loads following combined pre/post-treatment of cells, pre-treatment only, and post-treatment only conditions. The results identify combined pre/post-treatment as the most effective strategy in robustly reducing viral load between 2-4 logs.

Summary

Privacy is a fundamental human right, and a requirement for individual and community wellbeing.

However, privacy is also theoretically and practically contested and paradoxical.

A critical understanding of privacy emphasises the importance of power and harm, and how this might differentially and contextually impact individuals and communities.

Technological advance brings new categories of data, such as genomes, with which privacy rules need to be re-conceptualised and updated.

For open science to maintain its values of quality and integrity, and collective benefit, we need to update how we conceptualise privacy, especially in the face of rapid and disruptive technological advancement.

Recommendations

That open science explicitly adopt a more critical understanding of privacy that recognises underlying dynamics of harm and power that impact individuals and communities

That the governance frameworks and policies for open science apply this more critical understanding of privacy/power in their deliberation and practice. This includes, but is not limited to:

Reconceptualising new data types (e.g. genomes) and their key terminologies (e.g. what is identifiability; what is personal, familial, and communal).

Developing governance policies and frameworks that are responsive and agile to privacy risks, harms, and power relationships as technologies advances.

Making data controllers and users to follow codes of conduct that are agreed upon by data providers and multidisciplinary stakeholders.

Investigating the appropriateness of restorative and reparative approaches where (potential) harms arise.

That the training and development of open science professionals (such as data stewards) be provided opportunities to upskill in technical, social, legal, and political developments concerning privacy and related topics.

description: The strong coupling constant $α_s(μ)$ is extracted from the fits to charmonium spectrum and fine structure splittings. The relativistic kinematics is taken into account and relativistic corrections are shown to increase the matrix elements defining spin effects up to 40%. The value of $α_s(μ)$ at low-energy scale $μ=1.0 \pm 0.2 GeV$ was found to be $α_s(μ) = 0.38 \pm 0.03 (exp.) + 0.04 (theor.)$ which is about 50% lower than standard perturbative two-loop approximation and is in good agreement with the freezing $α_s$ behaviour.

Tensionless branes and the null string critical dimension

description: BRST quantization is carried out for a model of p-branes with second class constraints. After extension of the phase space the constraint algebra coincides with the one of null string when p=1. It is shown that in this case one can or can not obtain critical dimension for the null string, depending on the choice of the operator ordering and corresponding vacuum states. When p>1, operator orderings leading to critical dimension in the p=1 case are not allowed. Admissable orderings give no restrictions on the dimension of the embedding space-time. Finally, a generalization to supersymmetric null branes is proposed.

description: We survey results on mutations of Jacobian algebras, while simultaneously extending them to the more general setup of frozen Jacobian algebras, which arise naturally from dimer models with boundary and in the context of the additive categorification of cluster algebras with frozen variables via Frobenius categories. As an application, we show that the mutation of cluster-tilting objects in various such categorifications, such as the Grassmannian cluster categories of Jensen-King-Su, is compatible with Fomin-Zelevinsky mutation of quivers. We also describe an extension of this combinatorial mutation rule allowing for arrows between frozen vertices, which the quivers arising from categorifications and dimer models typically have.

description: We identify a plausible scenario based on quark-lepton symmetry which correlates long baseline oscillations with maximal mixing to sterile neutrinos. The implication for the Sudbury Neutrino Observatory (SNO) is that the neutral current signal will be found to suffer the same suppression from the Standard Solar Model prediction as obtains for the charged current signal. Flavor mixing among active neutrinos is expected to occur on shorter baselines with smaller mixing amplitudes.

Lifshitz-Slyozov Scaling For Late-Stage Coarsening With An Order-Parameter-Dependent Mobility

description: The coarsening dynamics of the Cahn-Hilliard equation with order-parameter dependent mobility, $λ(ϕ) \propto (1-ϕ^2)^α$, is addressed at zero temperature in the Lifshitz-Slyozov limit where the minority phase occupies a vanishingly small volume fraction. Despite the absence of bulk diffusion for $α>0$, the mean domain size is found to grow as $ \propto t^{1/(3+α)}$, due to subdiffusive transport of the order parameter through the majority phase. The domain-size distribution is determined explicitly for the physically relevant case $α= 1$.

g-coupling (g_B*Bpi,g_D*Dpi); A quark model with Dirac equation

description: We discuss the strong coupling of heavy mesons to a pion g, in the heavy quark limit. This quantity is quite remarkable since its values as estimated by different methods (various quark models and the QCD sum rules), are surprisingly different. The present quark models are mostly based on free spinors and their predictions depend crucially on the choice of the light quark mass. We propose a quark model based on the Dirac equation in a central potential, which gives a more refined description of Dirac spinors. We show that within such a Dirac model, the value of g is stable and large: g = 0.6(1), where we assume no quark current renormalization ((g_A)q = 1). Such a large result is strongly constrained by requiring that the model parameters fit the spectrum; we show that this implies a large ``effective'' light mass. It is also supported phenomenologically by a similar situation with heavy baryons, as well as by experience with nucleon (if one invokes additivity). We also calculate the couplings to heavy meson excitations, and show that the Adler-Weisberger sum rule is well saturated by a few levels (in contrast to the case of small g). We discuss uncertainties of our approach, and rise several questions which remain to be answered. The main mystery is the large, unusual discrepancy with QCD sum rules for g, whereas a good agreement is found for orbital excitations.

description: Well known methods of measure theory on infinite dimensional spaces are used to study physical properties of measures relevant to quantum field theory. The difference of typical configurations of free massive scalar field theories with different masses is studied. We apply the same methods to study the Ashtekar-Lewandowski (AL) measure on spaces of connections. We prove that the diffeomorphism group acts ergodically, with respect to the AL measure, on the Ashtekar-Isham space of quantum connections modulo gauge transformations. We also prove that a typical, with respect to the AL measure, quantum connection restricted to a (piecewise analytic) curve leads to a parallel transport discontinuous at every point of the curve.

Two-Dimensional Multiferroic Semiconductors with Coexisting Ferroelectricity and Ferromagnetism

description: Low-dimensional multiferroicity, though highly scarce in nature, has attracted great attention due to both fundamental and technological interests. Using first-principles density functional theory, we show that ferromagnetism and ferroelectricity can coexist in monolayer transition metal phosphorus chalcogenides (TMPCs) - CuMP$_2$X$_6$ (M=Cr, V; X=S, Se). These van der Waals layered materials represent a class of 2D multiferroic semiconductors that simultaneously possess ferroelectric and ferromagnetic orders. In these monolayer materials, Cu atoms spontaneously move away from the center atomic plane, giving rise to nontrivial electric dipole moment along the plane normal. In addition, their ferromagnetism originates from indirect exchange interaction between Cr/V atoms, while their out-of-plane ferroelectricity suggests the possibility of controlling electric polarization by external vertical electric field. Monolayer semiconducting TMPCs thus provide a solid-state 2D materials platform for realizing 2D nanoscale switches and memory devices patterned with top and bottom electrodes.

Impact of Laser Guide Star facilities on neighbouring telescopes: The case of GTC, TMT, VLT and ELT lasers and the Cherenkov Telescope Array

description: Powerful Laser Guide Star (LGS) systems are standard for the next-generation of extremely large telescopes. However, modern earth-based astronomy has gone through a process of concentration on few sites with exceptional sky quality, resulting in those becoming more and more crowded. The future LGS systems encounter hence an environment of surrounding astronomical installations, some of which observing with large fields-of-view. We derive formulae to calculate the impact of LGS light on the camera of a neighbouring telescope and the probabilities for a laser crossing the camera field-of-view to occur, and apply these to the specific case of the next very-high-energy gamma-ray observatory "Cherenkov Telescope Array" (CTA). Its southern part shall be constructed in a valley of the Cerro Armazones, Chile, close to the "Very Large Telescope" (VLT) and the "European Extremely Large Telescope" (ELT), while its northern part will be located at the "Observatorio del Roque de los Muchachos", on the Canary Island of La Palma, which also hosts the "Gran Telescopio de Canarias" (GTC) and serves as an optional site for the "Thirty Meter Telescope" (TMT), both employing LGS systems. Although finding the artificial star in the field-of-view of a CTA telescope will not disturb observations considerably, the laser beam crossing the field-of-view of a CTA telescope may be critical. We find no conflict expected for the ELT lasers, however, 1% (3%) of extra-galactic and 1% (5%) of galactic observations with the CTA may be affected by the GTC (TMT) LGS lasers, unless an enhanced version of a laser tracking control system gets implemented.
