description: We present the light curve of the old nova V603 Aql (Nova Aql 1918) from 1898-1918 and 1934-2013 using 22,721 archival magnitudes. All of our magnitudes are either in, or accurately transformed into, the Johnson $B$ and $V$ magnitude systems. This is vital because offsets in old sequences and the visual-to-$V$ transformation make for errors from 0.1-1.0 magnitude if not corrected. Our V603 Aql light curve is the first time that this has been done for any nova. Our goal was to see the evolution of the mass accretion rate on the century time scale, and to test the long-standing prediction of the Hibernation model that old novae should be fading significantly in the century after their eruption is long over. The 1918 nova eruption was completely finished by 1938 when the nova decline stopped, and when the star had faded to fainter than its pre-nova brightness of $B=11.43 \pm 0.03$ mag. We find that the nova light from 1938-2013 was significantly fading, with this being seen consistently in three independent data sets (the Sonneberg plates in $B$, the AAVSO $V$ light curve, and the non-AAVSO $V$ light curve). We find that V603 Aql is declining in brightness at an average rate of $0.44 \pm 0.04$ mag per century since 1938. This work provides remarkable confirmation of an important prediction of the Hibernation model.

description: Dense non-Brownian suspension flows of hard particles display mystifying properties: as the jamming threshold is approached, the viscosity diverges, as well as a length scale that can be identified from velocity correlations. To unravel the microscopic mechanism governing dissipation and its connection to the observed long-range correlations, we develop an analogy between suspension flows and the rigidity transition occurring when floppy networks are pulled -- a transition believed to be associated to the stress-stiffening of certain gels. After deriving the critical properties near the rigidity transition, we show numerically that suspensions flows lie close to it. We find that this proximity causes a decoupling between viscosity and the correlation length of velocities ξ, which scales as the length l_c characterizing the response of the velocity in flow to a local perturbation, previously predicted to follow l_c\sim 1/\sqrt{z_c-z}\sim p^{0.18} where p is the dimensionless particle pressure, z the coordination of the contact network made by the particles and z_c is twice the spatial dimension. We confirm these predictions numerically, predict the existence of a larger length scale l_r\sim 1/\sqrt{p} with mild effects on velocity correlation and the existence of a vanishing strain δγ\sim 1/p that characterizes de-correlation in flow.

description: We calculate the invariant and helicity amplitudes for the nonleptonic decay Lambda_b -> Lambda + J/psi, psi(2S) in the covariant confined quark model. We discuss joint angular decay distributions in the cascade decay Lambda_b -> Lambda(-> p pi-) + J/psi, psi(2S) (-> l+ l-) and calculate some of the asymmetry parameters that characterize the joint angular decay distribution. We confirm expectations from the naive quark model that the transitions into the lambda_Lambda=1/2 helicity states of the daughter baryon Lambda are strongly suppressed leading to a near maximal negative polarization of the Lambda. For the same reason the azimuthal correlation between the two decay planes spanned by (p pi-) and (l+ l-) is negligibly small. We provide form factor results for the whole accessible q2-range. Our results are close to lattice results at minimum recoil and light-cone sum rule results at maximum recoil. A new feature of our analysis is that we include lepton mass effects in the calculation which allows us to also describe the cascade decay Lambda_b -> Lambda(-> p pi-) + psi(2S)(-> tau+ tau-).

Error models in quantum computation: an application of model selection

description: Threshold theorems for fault-tolerant quantum computing assume that errors are of certain types. But how would one detect whether errors of the "wrong" type occur in one's experiment, especially if one does not even know what type of error to look for? The problem is that for many qubits a full state description is impossible to analyze, and a full process description is even more impossible to analyze. As a result, one simply cannot detect all types of errors. Here we show through a quantum state estimation example (on up to 25 qubits) how to attack this problem using model selection. We use, in particular, the Akaike Information Criterion. The example indicates that the number of measurements that one has to perform before noticing errors of the wrong type scales polynomially both with the number of qubits and with the error size.

description: Many advanced program analysis and verification methods are based on solving systems of Constrained Horn Clauses (CHC). Testing CHC solvers is very important, as correctness of their work determines whether bugs in the analyzed programs are detected or missed. One of the well-established and efficient methods of automated software testing is fuzzing: analyzing the reactions of programs to random input data. Currently, there are no fuzzers for CHC solvers, and fuzzers for SMT solvers are not efficient in CHC solver testing, since they do not consider CHC specifics. In this paper, we present HornFuzz, a mutation-based gray-box fuzzing technique for detecting bugs in CHC solvers based on the idea of metamorphic testing. We evaluated our fuzzer on one of the highest performing CHC solvers, Spacer, and found a handful of bugs in Spacer. In particular, some discovered problems are so serious that they require fixes with significant changes to the solver.
Transverse wobbling-a collective mode in odd-A triaxial nuclei

description: The wobbling motion of a triaxial rotor coupled to a high-j quasiparticle is treated semiclassi- cally. Longitudinal and transverse coupling regimes can be distinguished depending on, respectively, whether the quasiparticle angular momentum is oriented parallel or perpendicular to the rotor axis with the largest moment of inertia. Simple analytical expressions for the wobbling frequency and the electromagnetic E2 and M1 transition probabilities are derived assuming rigid alignment of the quasiparticle with one of the rotor axes and harmonic oscillations (HFA). Transverse wobbling is characterized by a decrease of the wobbling frequency with increasing angular momentum. Two examples for transverse wobbling, 163Lu and 135Pr, are studied in the framework of the full triax- ial particle-rotor model and the HFA. The signature of transverse wobbling, decreasing wobbling frequency and enhanced E2 inter-band transitions, is found in agreement with experiment.

MOBILE INTERNET AND MENTAL HEALTH

description: We study the relationship between 3G mobile internet rollout and mental health in the United States by combining the Behavioral Risk Factor Surveillance System (BRFSS) data with the Collins Bartholomew’s Mobile Coverage Explorer (MCE) data from 2011 to 2020. Unlike many existing studies that use state or county as the level of aggregation, our analysis uses a sample of metropolitan and micropolitan statistical areas. Based on our findings, 3G mobile internet has a substantial negative effect on mental health, and instrumenting 3G rollout with pre-existing 2G infrastructure suggests the effects are causal. Young cohorts with high education and income levels are more likely to experience adverse effects on their mental health.

description: We consider the problem of realistic bokeh rendering from a single all-in-focus image. Bokeh rendering mimics aesthetic shallow depth-of-field (DoF) in professional photography, but these visual effects generated by existing methods suffer from simple flat background blur and blurred in-focus regions, giving rise to unrealistic rendered results. In this work, we argue that realistic bokeh rendering should (i) model depth relations and distinguish in-focus regions, (ii) sustain sharp in-focus regions, and (iii) render physically accurate Circle of Confusion (CoC). To this end, we present a Defocus to Focus (D2F) framework to learn realistic bokeh rendering by fusing defocus priors with the all-in-focus image and by implementing radiance priors in layered fusion. Since no depth map is provided, we introduce defocus hallucination to integrate depth by learning to focus. The predicted defocus map implies the blur amount of bokeh and is used to guide weighted layered rendering. In layered rendering, we fuse images blurred by different kernels based on the defocus map. To increase the reality of the bokeh, we adopt radiance virtualization to simulate scene radiance. The scene radiance used in weighted layered rendering reassigns weights in the soft disk kernel to produce the CoC. To ensure the sharpness of in-focus regions, we propose to fuse upsampled bokeh images and original images. We predict the initial fusion mask from our defocus map and refine the mask with a deep network. We evaluate our model on a large-scale bokeh dataset. Extensive experiments show that our approach is capable of rendering visually pleasing bokeh effects in complex scenes. In particular, our solution receives the runner-up award in the AIM 2020 Rendering Realistic Bokeh Challenge.

The Gulabi Gang and the Case for Vigilante Justice in Weak States
Creators: name: Kelly, Lauren
Publisher: name: University of Chicago
Year: 2022

description: Citizen security is the concept of citizens being protected from crime and violence; this can be protection from external or internal forces in a state. What providers of security are best, and what conditions affect the quality of different security providers or guarantors? Most theorists agree that a strong state is the best provider of citizen security, but there still is a debate over whether a weak state or non-governmental organizations would be more effective and beneficial to the public. This paper is further situated in the conversation surrounding the role marginalization plays in this debate using the case studies of the Gulabi Gang and the Bakassi Boys to find that when the state does not work for marginalized people, they will provide their own security and this security will be better than state security. In order to better serve marginalized populations, there must first be an understanding of what security providers are best.

description: Recently demonstrated ghost interference using correlated photons of different frequencies, has been theoretically analyzed. The calculation predicts an interesting nonlocal effect: the fringe width of the ghost interference depends not only on the wave-length of the photon involved, but also on the wavelength of the other photon with which it is entangled. This feature, arising because of different frequencies of the entangled photons, was hidden in the original ghost interference experiment. This prediction can be experimentally tested in a slightly modified version of the experiment.

description: We present first analytic, resummed calculations of the rates at which widespread jet substructure tools tag QCD jets. As well as considering trimming, pruning and the mass-drop tagger, we introduce modified tools with improved analytical and phenomenological behaviours. Most taggers have double logarithmic resummed structures. The modified mass-drop tagger is special in that it involves only single logarithms, and is free from a complex class of terms known as non-global logarithms. The modification of pruning brings an improved ability to discriminate between the different colour structures that characterise signal and background. As we outline in an extensive phenomenological discussion, these results provide valuable insight into the performance of existing tools and help lay robust foundations for future substructure studies.

description: We show that, within the AdS/CFT correspondence, recent formulations of the information paradox can be reduced to a question about the existence of certain kinds of operators in the CFT. We describe a remarkably simple construction of these operators on a given state of the CFT. Our construction leads to a smooth horizon, addresses the strong subadditivity paradox, while preserving locality within effective field theory, and reconciles the existence of the interior with the growth of states with energy in the CFT. We also extend our construction to non-equilibrium states.

description: Asteroseismic scaling relations can provide high-precision measurements of mass and radius for red giant (RG) stars displaying solar-like oscillations. Their accuracy can be validated and potentially improved using independent and accurate observations of mass, radius, effective temperature and metallicity. We seek to achieve this using long period SB2 eclipsing binaries hosting oscillating RGs. We explore KIC 8430105, for which a previous study found significant asteroseismic overestimation of mass and radius when compared with eclipsing binary measurements. We measured dynamical masses and radii for both components to be significantly lower than previously established, increasing the discrepancy between asteroseismic and dynamical measurements. Our dynamical measurements of the RG component were compared to corresponding measurements of mass and radius using asteroseismic scaling relations. Uncorrected scaling relations overestimated the mass of the RG by 26%, the radius by 11%, and the average density by 7%, in agreement with studies for other systems. However, using a theoretical correction to $Δν$, we managed to obtain an asteroseismic average density that is $1σ$ consistent with our dynamical result. We obtained several measurements of $ν_{max}$ that are not fully consistent. With $ν_{max} = 76.78 \pm 0.81μ$Hz, the $Δν$ correction provided $2 σ$ consistent mass and radius for the giant. The age of the system was estimated to be $3.7 \pm 0.4$ Gyr.

Moreover, it presents the priorities we set up based on Big Data Value Association (BDVA) priorities, the Innovation Strategy Plan and the IPR management approach. The first results of innovation monitoring throughout the different project activities are also presented. A section is devoted to each main building block of the architecture (i.e. data-driven infrastructure management, data-as-a-service, as well as dimensioning, modelling, and interaction services), presenting the innovation-monitored components, the related priorities, their expected innovation and the progress towards it. Another section describes the expected innovation of BigDataStack use cases and their approach. In the course of the project, the BigDataStack components and use cases will continue being monitored to ensure that the innovation potential of the project will be fully exploited. A follow-up deliverable (i.e. D1.3) summarizing BigDataStack activities relevant to Innovation Potential will be delivered at M34.

description: The thermal properties of a system, comprising of a spinless non-interacting charged particle in the presence of a constant external magnetic field and confined in a parabolic quantum well are studied. The focus has been on the effects of a topological defect, of the form of conical disclination, with regard to the thermodynamic properties of the system. We have obtained the modifications to the traditional Landau-Fock-Darwin spectrum in the presence of conical disclination. The effect of the conical kink on the degeneracy structure of the energy levels is investigated. The canonical formalism is used to compute various thermodynamic variables. The study shows an interplay between magnetic field, temperature and the degree of conicity by setting two scales for temperature corresponding to the frequency of the confining potential and the cyclotron frequency of external magnetic field. The kink parameter is found to affect the quantitative behaviour of the thermodynamic quantities. It plays a crucial role in the competition between the external magnetic field and temperature in fixing the values of the thermal response functions. This study provides an important motivation for studying similar systems, however with non trivial interactions in the presence of topological defects.

description: What explains differences in democratic backsliding? As transitions from authoritarianism to democracy follow different paths, so does the erosion of democracy into authoritarianism. While most of the current literature on democratic backsliding focuses on the concentration of power in the executive as a precursor an expression of backsliding, some democracies backslide while sustaining highly constrained executives. I explore the cases of Guatemala and El Salvador to suggest that processes set forth at the onset of democracy resulted in diverging regime characteristics and particular backsliding paths, three decades later.

Biological control

description: Manuka beetle (Pyronota festiva, Pyronota laeta, Pyronota setosa) and the New Zealand grass grub (Costelytra giveni) have overlapping distributions across parts of New Zealand as well as similar seasonal life cycles. Grass grub is the most damaging pasture pest in terms of economic losses while manuka beetle causes significant damage in key regions including the South Island’s West Coast and the North Island’s Central Plateau. Where manuka beetle and grass grub overlap, knowing which species is present in your pasture informs decisions about pest control. This has become even more important with the expansion of grass grub into coastal Buller, with potential for further spread and poses a new challenge to pastoral farmers in the region. Whilst it is possible to differentiate the larvae based on external morphology under a microscope, it requires entomological expertise and an expert eye. Here we outline a simple molecular method, based on restriction digestion of the mitochondrial cytochrome c oxidase subunit I (COI) gene, to facilitate the rapid identification and differentiation of C. giveni larvae from Pyronota species. The ability to differentiate these species in regions where they co-occur will assist with long-term management of these endemic pasture pests and allow studies investigating possible heterogeneity in the efficacy of biological control measures.

description: In der heutigen Industrie ist die Automatisierung ein allgegenwärtiger Faktor, selbst in Nischenanwendungen wie der Kryokonservierung. Die manuelle Handhabung von biologischen oder toxischen Proben ist in Forschungseinrichtungen immer noch die Norm. Die Konservierung und Lagerung solcher Proben erfolgt in sogenannten Kryobanken bei Temperaturen zwischen -130 °C und -196 °C. In heute üblichen Kryobanken werden die Proben oft mit sperriger Schutzkleidung von Hand ein- und ausgelagert oder bewegt. Dies ist notwendig, da ein erhebliches Verletzungsrisiko für den Arbeiter durch Kälteverbrennungen sowie eine Gefährdung der Probenintegrität durch Beschädigung und Erwärmung oder auch Temperaturwechsel besteht. Zur Überwindung dieser Probleme ist eine Vollautomatisierung bei Temperaturen unter -130 °C wünschenswert. In diesem Beitrag wird das von der DFG geförderte Projekt "Methoden zur Automatisierung von Handhabungsprozessen unter kryogenen Umgebungs-bedingungen" vorgestellt und erläutert. Dabei wird besonders auf die Teilaspekte der Greifertechnologie sowie der Optimierung der verwendeten Festkörpergelenke eingegangen.

description: Interest in many strongly spin-orbit coupled 5d-transition metal oxide insulators stems from mapping their electronic structures to a J=1/2 Mott phase. One of the hopes is to establish their Mott parent states and explore these systems' potential of realizing novel electronic states upon carrier doping. However, once doped, little is understood regarding the role of their reduced Coulomb interaction U relative to their strongly correlated 3d-electron cousins. Here we show that, upon hole-doping a candidate J=1/2 Mott insulator, carriers remain localized within a nanoscale phase separated ground state. A percolative metal-insulator transition occurs with interplay between localized and itinerant regions, stabilizing an antiferromagnetic metallic phase beyond the critical region. Our results demonstrate a surprising parallel between doped 5d- and 3d-electron Mott systems and suggest either through the near degeneracy of nearby electronic phases or direct carrier localization that U is essential to the carrier response of this doped spin-orbit Mott insulator.

description: We study the electric dipole polarizability $α_D$ in ${}^{208}$Pb based on the predictions of a large and representative set of relativistic and non-relativistic nuclear mean field models. We adopt the droplet model as a guide to better understand the correlations between $α_D$ and other isovector observables. Insights from the droplet model suggest that the product of $α_D$ and the nuclear symmetry energy at saturation density $J$ is much better correlated with the neutron skin thickness $Δr_{np}$ of ${}^{208}$Pb than the polarizability alone. Correlations of $α_D J$ with $Δr_{np}$ and with the symmetry energy slope parameter $L$ suggest that $α_D J$ is a strong isovector indicator. Hence, we explore the possibility of constraining the isovector sector of thenuclear energy density functional by comparing our theoretical predictions against measurements of both $α_D$ and the parity-violating asymmetry in ${}^{208}$Pb. We find that the recent experimental determination of $α_D$ in ${}^{208}$Pb in combination with the range for the symmetry energy at saturation density $J=[31\pm (2)_{\rm est.}]$\,MeV suggests $Δr_{np}({}^{208}{\rm Pb}) = 0.165 \pm (0.009)_{\rm exp.} \pm (0.013)_{\rm theo.} \pm (0.021)_{\rm est.} {\rm fm}$ and $L= 43 \pm(6)_{\rm exp.} \pm (8)_{\rm theo.}\pm(12)_{\rm est.}$ MeV.

description: The exquisite control exhibited over quantum states of individual particles has revolutionized the field of precision measurement, as exemplified by the most accurate atomic clock realized in single trapped ions. Whereas many-atom lattice clocks have shown advantages in measurement precision over trapped-ion clocks, their accuracy has remained 20 times worse. Here we demonstrate, for the first time, that a many-atom system achieves accuracy (6x10^{-18}) better than a single ion-based clock, with vastly reduced averaging times (3000 s). This is the first time a single clock has achieved the best performance in all three key ingredients necessary for consideration as a primary standard - stability, reproducibility, and accuracy. This work paves the way for future experiments to integrate many-body quantum state engineering into the frontiers of quantum metrology, creating exciting opportunities to advance precision beyond the standard quantum limit. Improved frequency standards will have impact to a wide range of fields from the realization of the SI units, the development of quantum sensors, to precision tests of the fundamental laws of nature.

Diaspora Groups and the Duration of Civil War
Creators: name: Mukhopadhyay, Indrajit
Publisher: name: University of Chicago
Year: 2022

description: Previous studies examining civil war have been limited in overlooking transnational factors. One of these factors are diaspora, groups who despite migrating from their homeland, stay oriented to it, and often involve themselves when conflict occurs. With international migrant stocks estimated at 3.6% of the world’s population they embody a potent force, representing a significant and puzzling omission in the analysis of the determinants of civil war. In this thesis, identifying three mechanisms of mobilized diaspora involvement, I argue that diaspora group involvement leads to longer duration homeland conflicts. I test these hypotheses in a quantitative study, using new data and novel diaspora mobilization variables. Using a Cox (1972) proportional hazards model I find evidence that all three mechanisms of diaspora involvement in their homeland increases the likelihood of longer duration civil wars, following the expectations of my hypotheses.

description: We provide a simple and explicit construction of local bulk operators that describe the interior of a black hole in the AdS/CFT correspondence. The existence of these operators is predicated on the assumption that the mapping of CFT operators to local bulk operators depends on the state of the CFT. We show that our construction leads to an exactly local effective field theory in the bulk. Barring the fact that their charge and energy can be measured at infinity, we show that the commutator of local operators inside and outside the black hole vanishes exactly, when evaluated within correlation functions of the CFT. Our construction leads to a natural resolution of the strong subadditivity paradox of Mathur and Almheiri et al. Furthermore, we show how, using these operators, it is possible to reconcile small corrections to effective field theory correlators with the unitarity of black hole evaporation. We address and resolve all other arguments, advanced in arxiv:1304.6483 and arxiv:1307.4706, in favour of structure at the black hole horizon. We extend our construction to states that are near equilibrium, and thereby also address the "frozen vacuum" objections of arxiv:1308.3697. Finally, we explore an intriguing link between our construction of interior operators and Tomita-Takesaki theory.

description: We investigate the interplay between jets from Active Galactic Nuclei (AGNs) and the surrounding InterStellar Medium (ISM) through full 3D, high resolution, Adaptive Mesh Refinement simulations performed with the FLASH code. We follow the jet- ISM system for several Myr in its transition from an early, compact source to an extended one including a large cocoon. During the jet evolution, we identify three major evolutionary stages and we find that, contrary to the prediction of popular theoretical models, none of the simulations shows a self-similar behavior. We also follow the evolution of the energy budget, and find that the fraction of input power deposited into the ISM (the AGN coupling constant) is of order of a few percent during the first few Myr. This is in broad agreement with galaxy formation models employing AGN feedback. However, we find that in these early stages, this energy is deposited only in a small fraction (< 1%) of the total ISM volume. Finally we demonstrate the relevance of backflows arising within the extended cocoon generated by a relativistic AGN jet within the ISM of its host galaxy, previously proposed as a mechanism for self-regulating the gas accretion onto the central object. These backflows tend later to be destabilized by the 3D dynamics, rather than by hydrodynamic (Kelvin- Helmholtz) instabilities. Yet, in the first few hundred thousand years, backflows may create a central accretion region of significant extent, and convey there as much as a few millions of solar masses.

description: We systematically discuss connections on the spinor bundle of Cahen-Wallach symmetric spaces. A large class of these connections is closely connected to a quadratic relation on Clifford algebras. This relation in turn is associated to the symmetric linear map that defines the underlying space. We present various solutions of this relation. Moreover, we show that the solutions we present provide a complete list with respect to a particular algebraic condition on the parameters that enter into the construction.

description: We associate vertex operators to space-time diffeomorphisms in flat space string theory, and compute their algebra, which is a diffeomorphism algebra with higher derivative corrections. As an application, we realize the asymptotic symmetry group BMS3 of three-dimensional flat space in terms of vertex operators on the string worldsheet. This provides an embedding of the BMS3 algebra in a consistent theory of quantum gravity. Higher derivative corrections vanish asymptotically. An appendix is dedicated to alpha prime corrected algebras in conformal field theory and string theory.
