description: We extend earlier numerical and analytical considerations of the conformally invariant wave equation on a Schwarzschild background from the case of spherically symmetric solutions, discussed in Class. Quantum Grav. 34, 045005 (2017), to the case of general, nonsymmetric solutions. A key element of our approach is the modern standard representation of spacelike infinity as a cylinder. With a decomposition into spherical harmonics, we reduce the four-dimensional wave equation to a family of two-dimensional equations. These equations can be used to study the behaviour at the cylinder, where the solutions turn out to have logarithmic singularities at infinitely many orders. We derive regularity conditions that may be imposed on the initial data, in order to avoid the first singular terms. We then demonstrate that the fully pseudospectral time evolution scheme can be applied to this problem leading to a highly accurate numerical reconstruction of the nonsymmetric solutions. We are particularly interested in the behaviour of the solutions at future null infinity, and we numerically show that the singularities spread from the cylinder to null infinity. The observed numerical behaviour is consistent with similar logarithmic singularities found analytically on the cylinder. Finally, we demonstrate that even solutions with singularities at low orders can be obtained with high accuracy by virtue of a coordinate transformation that converts functions with logarithmic singularities into smooth solutions.

Relativistic Hydrodynamic Attractors with Broken Symmetries: Non-Conformal and Non-Homogeneous

description: Standard textbooks will state that hydrodynamics requires near-equilibrium to be applicable. Recently, however, out-of-equilibrium attractor solutions for hydrodynamics have been found in kinetic theory and holography in systems with a high degree of symmetry, suggesting the possibility of a genuine out-of-equilibrium formulation of hydrodynamics. This work demonstrates that attractor solutions also occur in non-conformal kinetic theory and spatially non-homogeneous systems, potentially having important implications for the interpretation of experimental data in heavy-ion and proton-proton collisions and relativistic fluid dynamics as a whole.

description: We study the influence of a randomly switching reproduction-predation rate on the survival behavior of the non-spatial cyclic Lotka-Volterra model, also known as the zero-sum rock-paper-scissors game, used to metaphorically describe the cyclic competition between three species. In large and finite populations, demographic fluctuations (internal noise) drive two species to extinction in a finite time, while the species with the smallest reproduction-predation rate is the most likely to be the surviving one ("law of the weakest"). Here, we model environmental (external) noise by assuming that the reproduction-predation rate of the "strongest species" (the fastest to reproduce/predate) in a given static environment randomly switches between two values corresponding to more and less favorable external conditions. We study the joint effect of environmental and demographic noise on the species survival probabilities and on the mean extinction time. In particular, we investigate whether the survival probabilities follow the law of the weakest and analyze their dependence of the external noise intensity and switching rate. Remarkably, when, on average, there is a finite number of switches prior to extinction, the survival probability of the predator of the species whose reaction rate switches typically varies non-monotonically with the external noise intensity (with optimal survival about a critical noise strength). We also outline the relationship with the case where all reaction rates switch on markedly different time scales.

Unroutable LHCONE traffic

Publisher: name: Zenodo
Year: 2019

description: This talk explores the methods and results confirming the baseline assumption that LHCONE traffic is science traffic. The LHCONE (LHC Open Network Environment) is a network conceived to support globally distributed collaborative science. The LHCONE connects thousands of researchers to LHC data sets at hundreds of universities and labs performing analysis within the global collaboration. It is "Open" to all levels of the LHC as well as a short list of approved non-LHC science collaborations. It is distinct from the smaller, tightly integrated and private LHCOPN (Optical Private Network) network which is strictly for "Tier 1" compute centers and used in support of the engineered workflow for LHC data processing, distribution and longtime storage of the baseline datasets. LHCONE satisfies the need for a high performance global data transfer network of networks supporting scientific analysis at universities and science labs. **Science traffic separation is the hard part** The separation of science flows from non-science flows, is an essential first step in traffic engineering high performance science networks. Before resources or preference can be applied to more effectively move science data, it is essential to identify and separate the science from non-science traffic. This talk explores the methods and results in detecting traffic in the LHCONE network that does not comply with the Appropriate Use Policy established by the global LHC collaboration. **LHCONE hosts are high performance** Through integration of the Science DMZ network model and collaborative software platforms. The data transfer nodes connected to LHCONE are high performing data movers placed on the network edge/Science DMZ and secured precisely according to the applications they support and the purpose they serve. **LHCONE is at risk of unauthorized use** Unauthorized use of LHCONE places both the network and the sites using it at risk. The risk takes two forms: Science flows are mixing with non-science flows or unauthorized traffic is being dropped inside LHCONE. **Identifying unauthorized traffic** An EDUgain authenticated portal visualizing unauthorized usage will be demonstrated. For keeping track of the frequent changes of LHCONE the underlying database will be maintained and administered cooperatively by the LHC and NREN community.
Does the universe in fact contain almost no information?

description: At first sight, an accurate description of the state of the universe appears to require a mind-bogglingly large and perhaps even infinite amount of information, even if we restrict our attention to a small subsystem such as a rabbit. In this paper, it is suggested that most of this information is merely apparent, as seen from our subjective viewpoints, and that the algorithmic information content of the universe as a whole is close to zero. It is argued that if the Schrödinger equation is universally valid, then decoherence together with the standard chaotic behavior of certain non-linear systems will make the universe appear extremely complex to any self-aware subsets that happen to inhabit it now, even if it was in a quite simple state shortly after the big bang. For instance, gravitational instability would amplify the microscopic primordial density fluctuations that are required by the Heisenberg uncertainty principle into quite macroscopic inhomogeneities, forcing the current wavefunction of the universe to contain such Byzantine superpositions as our planet being in many macroscopically different places at once. Since decoherence bars us from experiencing more than one macroscopic reality, we would see seemingly complex constellations of stars etc, even if the initial wavefunction of the universe was perfectly homogeneous and isotropic.

description: Black and brown men are negatively impacted by the criminal justice system and have been incarcerated at higher rates than any other group in the United States (Knafo, 2013). The United States criminal justice system is built on punishment and exploitation rather than rehabilitation, resulting in higher rates of incarceration and recidivism compared to other developed nations (Gilligan, 2012). Countries such as Norway and the United Kingdom take a more humane approach to their criminal justice system, resulting in low recidivism rates (Sterbenz, 2014). Implementing policies that aim to keep families connected with individuals who are incarcerated is a major way to reduce recidivism rates (Clarke, 2013). Using New York State as a case study, this paper will propose extending conjugal visits beyond medium and low-security prisons and implementing Skype technology in prisons and jails as policy solutions to promote the well-being of people who are incarcerated and keep them from returning to prison once they are released. Social workers can play a vital role in efforts made to shift the United States’ criminal justice system from a culture of punishment towards a restorative model.
Physics Inspired Deep Neural Networks for Top Quark Reconstruction

Publisher: name: Zenodo
Year: 2019

description: Deep neural networks (DNNs) have been applied to the fields of computer vision and natural language processing with great success in recent years. The success of these applications has hinged on the development of specialized DNN architectures that take advantage of specific characteristics of the problem to be solved, namely convolutional neural networks for computer vision and recurrent neural networks for natural language processing. This research explores whether a neural network architecture specific to the task of identifying t→Wb decays in particle collision data yields better performance than a generic, fully-connected DNN. This approach is inspired by an DNN technique for tagging boosted top quarks, which consists of defining custom neural network layers known as the combination and Lorentz layers. These layers encode knowledge of relativistic kinematics applied to combinations of particles, and the output of these specialized layers can then be fed into a fully connected neural network to learn tasks such as classification. This research compares the performance of these physics inspired networks to that of a generic, fully-connected DNN, to see if there is any advantage in terms of classification performance, size of the network, or ease of training.

description: Within psychology, neuroscience and artificial intelligence, there has been increasing interest in the proposal that the brain builds probabilistic models of sensory and linguistic input: that is, to infer a probabilistic model from a sample. The practical problems of such inference are substantial: the brain has limited data and restricted computational resources. But there is a more fundamental question: is the problem of inferring a probabilistic model from a sample possible even in principle? We explore this question and find some surprisingly positive and general results. First, for a broad class of probability distributions characterised by computability restrictions, we specify a learning algorithm that will almost surely identify a probability distribution in the limit given a finite i.i.d. sample of sufficient but unknown length. This is similarly shown to hold for sequences generated by a broad class of Markov chains, subject to computability assumptions. The technical tool is the strong law of large numbers. Second, for a large class of dependent sequences, we specify an algorithm which identifies in the limit a computable measure for which the sequence is typical, in the sense of Martin-Lof (there may be more than one such measure). The technical tool is the theory of Kolmogorov complexity. We analyse the associated predictions in both cases. We also briefly consider special cases, including language learning, and wider theoretical implications for psychology.

Energy spectrum, the spin polarization, and the optical selection rules of the Kronig-Penney superlattice model with spin-orbit coupling

description: The Kronig-Penney model, an exactly solvable one-dimensional model of crystal in solid physics, shows how the allowed and forbidden bands are formed in solids. In this paper, we study this model in the presence of both strong spin-orbit coupling and the Zeeman field. We analytically obtain four transcendental equations that represent an implicit relation between the energy and the Bloch wavevector. Solving these four transcendental equations, we obtain the spin-orbital bands exactly. In addition to the usual band gap opened at the boundary of the Brillouin zone, a much larger spin-orbital band gap is also opened at some special sites inside the Brillouin zone. The $x$-component of the spin-polarization vector is an even function of the Bloch wavevector, while the $z$-component of the spin-polarization vector is an odd function of the Bloch wavevector. At the band edges, the optical transition rates between adjacent bands are nonzero.

description: Cloud computing is becoming mainstream, with funding agencies moving beyond prototyping and starting to fund production campaigns, too. An important aspect of any production computing campaign is data movement, both incoming and outgoing. And while the performance and cost of VMs is relatively well understood, the network performance and cost is not. We thus embarked on a network characterization campaign, documenting traceroutes, latency and throughput in various regions of Amazon AWS, Microsoft Azure and Google GCP Clouds, both between Cloud resources and major DTNs in the Pacific Research Platform, including OSG data federation caches in the network backbone, and inside the clouds themselves. We also documented the incurred cost while doing so. Along the way we discovered that network paths were often not what the major academic network providers thought they were, and we helped them in improving the situation, thus improving peering between academia and commercial cloud. In this talk we present the observed results, both during the initial test runs and the latest state of the art, as well as explain what it took to get there.
Kitaev-Heisenberg Hamiltonian for High-Spin $d^7$ Mott Insulators

description: In the search for quantum spin liquids, candidate materials for the Kitaev model and its extensions have been intensively explored during the past decade, as the models realize the exact quantum spin liquids in the ground state. Thus far, insulating magnets in the low-spin $d^5$ electron configuration under the strong spin-orbit coupling have been studied for realizing the Kitaev-type bond-dependent anisotropic interactions between the spin-orbital entangled Kramers doublets. To extend the candidates, here we investigate the systems in a high-spin $d^7$ electron configuration, whose ground state is described by the spin-orbital entangled Kramers doublet. By the second- order perturbation in terms of the $t_{2g}$-$t_{2g}$ and $t_{2g}$-$e_g$ hoppings, we show that the effective spin model possesses the anisotropic Kitaev interactions as well as the isotropic Heisenberg ones. While the Kitaev interaction is always ferromagnetic, the Heisenberg interaction can become either ferromagnetic or antiferromagnetic depending on the Coulomb interactions and the crystalline electric fields. We also derive the effective model for the low-spin $d^5$ electron configuration within the same perturbation scheme, in which the Kitaev interaction becomes both ferromagnetic and antiferromagnetic, while the Heisenberg one always ferromagnetic. Referring to the previous study for the Kitaev-Heisenberg model, we find that the quantum spin liquid phase exists in the reasonable parameter region in both $d^7$ and $d^5$ cases, while the former has a richer structure of the phase diagram. We discuss the advantages of the $d^7$ case in comparison with the $d^5$ case. Our results indicate that the high-spin $d^7$ state provides another platform for the Kitaev-type quantum spin liquid.
Saving Children or Blaming Parents? Lessons from Mandated Parenting Classes
Creators: Schaefer, Tali
Publisher: name: Columbia University
Year: 2010
Subjects: subject: Law
subject: FOS: Law

description: In this Article, Part I explores the characteristics of legally mandated parent education programs. The programs are generally short, educational interventions and their main goal is to improve children's well-being during and after a divorce by teaching parents how to better interact with children and with each other. This Part argues that the literature documents programs' scant success in achieving their stated goals. The Article then makes a brief interlude, in Part II, to contend that although mandatory parenting classes appeal to common sense, we ought to challenge such a reaction in order to allow for a critical analysis of the legislation. Drawing on previously unexplored legislative materials, Part III explores judges' and lawmakers' inflated estimation of the harm caused by divorce and analyzes its influence on the resulting legislation. This Part relies on substantial empirical work, gathering and analyzing detailed minutes and recordings of committee meetings, public hearings, and floor presentations and votes. The choice of states for this study was therefore influenced by the availability of these primary sources. Still, the information represents diverse states and the analysis shows patterns common to all of them. The primary source data is complemented by public reports, news reports and papers written by key players in the enactment process: judges, parent educators, and lawyers. Part IV.A shows that legislators perceive harm to children as arising from personal flaws or failures of divorcing parents, as evidenced by the parents' decision to divorce - specifically, parents' selfishness or self-involvement. This Part goes on to argue that legislators' interest in confronting divorcing parents with the results of their allegedly detrimental actions has severely undermined the potential of these mandates to achieve their declared goal of helping children. Part IV .B develops further the claim that parent education mandates downplay the extent to which social, economic and legal conditions shape parents' behavior after divorce, especially gender roles and gender inequality. To conclude, this Article argues that judges and lawmakers should see divorce as no different from other stressful life events. If we want interventions targeting individuals, we should focus them on helping parents make the transition from married to divorced, as rapidly and painlessly as possible by preparing them to the structural problems they are likely to face upon separation. More importantly, this Article suggests that lawmakers should focus on changing these structural conditions instead of denying them through parent-blaming.

description: Using the third data release of the Sloan Digital Sky Survey (SDSS) we have rigorously defined a volume limited sample of early-type galaxies in the redshift range z < 0.1. We have defined the density of the local environment for each galaxy using a method which takes account of the redshift bias introduced by survey boundaries if traditional methods are used. At luminosities greater than our absolute r-band magnitude cutoff of -20.45 the mean density of environment shows no trend with redshift. We calculate the Lick indices for the entire sample and correct for aperture effects and velocity dispersion in a model independent way. Although we find no dependence of redshift or luminosity with environment we do find that the mean velocity dispersion, sigma, of early-type galaxies in dense environments tends to be higher than in low density environments. Taking account of this effect we find that several indices show small but very significant trends with environment that are not the result of the correlation between indices and velocity dispersion. The statistical significance of the data is sufficiently high to reveal that models accounting only for alpha-enhancement struggle to produce a consistent picture of age and metallicity of the sample galaxies, whereas a model that also includes carbon enhancement fares much better. We find that early-type galaxies in the field are younger than those in environments typical of clusters but that neither metallicity, alpha-enhancement nor carbon enhancement are influenced by the environment. The youngest early-type galaxies in both field and cluster environments are those with the lowest sigma. However, there is some evidence that the objects with the largest sigma are slightly younger, especially in denser environments.

description: Where collider searches for resonant invisible particles loose steam, dark sectors might leave their trace as virtual effects in precision observables. Here we explore this option in the framework of Higgs portal models, where a sector of dark fermions interacts with the standard model through a strong renormalizable coupling to the Higgs boson. We show that precise measurements of Higgs-gauge and triple Higgs interactions can probe dark fermions up to the TeV scale through virtual corrections. Observation prospects at the LHC and future lepton colliders are discussed for the so-called singlet-doublet model of Majorana fermions, a generalization of the bino-higgsino scenario in supersymmetry. We advocate a two-fold search strategy for dark sectors through direct and indirect observables.

description: The aim of this systematic review and meta-analysis was to compile the data examining the association between the CTLA4 + 49 A/G polymorphism and the risk for HCC. Multiple databases were systematically searched for eligible studies and the pooled odds ratios (ORs) were generated using five genetic models. Pooled data from 11 studies with 3,055 HCC patients and 3,450 controls found no statistically significant association between the polymorphism and HCC risk, both overall and in subgroup analyses. In conclusion, the current meta-analysis shows that the CTLA4 + 49 A/G polymorphism is not significantly associated with the risk of developing HCC.

description: We study the intrinsic fully-gapped odd-parity superconducting order in doped nodal-loop materials with a torus-shaped Fermi surface. We show that the mirror symmetry, which protects the nodal loop in the normal state, also protects the superconducting state as a topological crystalline superconductor. As a result, the surfaces preserving the mirror symmetry host gapless Majorana cones. Moreover, for a Weyl loop system (two-fold degenerate at the nodal loop), the surfaces that break the mirror symmetry (those parallel to the bulk nodal loop) contribute a Chern (winding) number to the quasi-two-dimensional system in a slab geometry, which leads to a quantized thermal Hall effect and a single Majorana zero mode bound at a vortex line penetrating the system. This Chern number can be viewed as a higher-order topological invariant, which supports hinge modes in a cubic sample when mirror symmetry is broken. For a Dirac loop system (four-fold degenerate at the nodal loop), the fully gapped odd-parity state can be either time-reversal symmetry-breaking or symmetric, similar to the $A$- and $B$- phases of $^3$He. In a slab geometry, the $A$-phase has a Chern number two, while the $B$-phase carries a nontrivial $\mathbb{Z}_2$ invariant. We discuss the experimental relevance of our results to nodal-loop materials such as CaAgAs.

description: Superconducting qubits are hampered by flux noise produced by surface spins from a variety of microscopic sources. Recent experiments indicated that hydrogen (H) atoms may be one of those sources. Using density functional theory calculations, we report that H atoms either embedded in, or adsorbed on, an a-Al2O3(0001) surface have sizeable spin moments ranging from 0.81 to 0.87 uB with energy barriers for spin reorientation as low as ~10 mK. Furthermore, H adatoms on the surface attract gas molecules such as O2, producing new spin sources. We propose coating the surface with graphene to eliminate H-induced surface spins and to protect the surface from other adsorbates.

description: We show in a rigorous way that Crum's result on equal eigenvalue spectrum of Sturm-Liouville problems can be obtained iteratively by successive Darboux transformations. It can be shown that all neighbouring Darboux-transformed potentials of higher order, u_{k} and u_{k+1}, satisfy the condition of shape invariance provided the original potential u does. We use this result to proof that under the condition of shape invariance the n-th iteration of the original Sturm-Liouville problem defined through shape invariance is equal to the n-th Crum transformation

description: siRNA is an important tool for modulating gene expression in current biomedical research. It would be highly desirable for siRNA to respond to an external stimulus. In this paper, we report a convenient, photolabile caging agent to regulate siRNA functions. 2-bromo-4’-hydroxyacetophenone (BHAP) can readily modify phosphorothioate backbones and inhibit siRNAs. Mild UV irradiation will cleave the modifying moiety to generate natural nucleic acid backbones, thus activating siRNA functions. Such modification is conveniently conducted in an aqueous solution with high efficiency and is cost-effective and scalable. This approach provides a convenient tool for the controlled regulation of gene expression by deploying minimal usage of complex organic synthesis for site-specific installation of the caging group to siRNA unlike previous reported works that required a series of intricate organic synthesis and cumbersome purification techniques to achieve similar aims. This study will open new doors for optochemical regulation of a variety of genes by pHP caging group in mammalian cell culture.

description: In public broadcasting, the primary goal of interviewing an expert is to inform and educate the audience for the benefit of societal interests (Clayman, 2013). Previous work on news interviews has noted that this type of public discourse not only involves the host and the expert, but also an overhearing audience (Clayman & Heritage, 2002; Hutchby, 1995); moreover, the host is positioned as the “tribune” of the people (Clayman, 2002), tasked with the responsibility to maximize the public’s understanding of and knowledge about what may concern them. While the audience as the third party in the question-answer sequence in news interviews has received considerable attention in the literature, less is known about how the interviewer works with the health expert’s responses to questions in order to facilitate the audience’s understanding of health initiatives. In this paper, we examine how the interviewer designs a follow-up turn to (1) provide background or supplemental information which contextualizes the interviewee’s prior response and to (2) reformulate the expert’s explanation from the perspective of the general public, thereby facilitating the audience’s understanding of initiatives pertaining to public health.

description: Stellar shells are low surface brightness arcs of overdense stellar regions, extending to large galactocentric distances. In a companion study, we identified 39 shell galaxies in a sample of 220 massive ellipticals ($\mathrm{M}_{\mathrm{200crit}}>6\times10^{12}\,\mathrm{M}_\odot$) from the Illustris cosmological simulation. We used stellar history catalogs to trace the history of each individual star particle inside the shell substructures, and we found that shells in high-mass galaxies form through mergers with massive satellites (stellar mass ratios $μ_{\mathrm{stars}}\gtrsim1:10$). Using the same sample of shell galaxies, the current study extends the stellar history catalogs in order to investigate the metallicity of stellar shells around massive galaxies. Our results indicate that outer shells are often times more metal-rich than the surrounding stellar material in a galaxy's halo. For a galaxy with two different satellites forming $z=0$ shells, we find a significant difference in the metallicity of the shells produced by each progenitor. We also find that shell galaxies have higher mass-weighted logarithmic metallicities ([Z/H]) at $2$-$4\,\mathrm{R}_{\mathrm{eff}}$ compared to galaxies without shells. Our results indicate that observations comparing the metallicities of stars in tidal features, such as shells, to the average metallicities in the stellar halo can provide information about the assembly histories of galaxies.

description: The development of antiretroviral therapies (ARTs) has significantly lengthened the lifespan and changed the life course of most individuals infected with HIV and AIDS in the United States. Furthermore, ART use during pregnancy has significantly reduced the rate of mother-to-child (perinatal) HIV transmission. While perinatal infection rates among children in the United States have declined since the 1990s, ART regimens became standard treatment protocol, there remains a population of children entering adolescence who were born with HIV-positive. This paper discusses: 1) the importance of diagnostic disclosure of HIV and AIDS status to infected children, 2) stigma and the disclosure process with children, and 3) the role of clinical social workers in facilitating the disclosure process.

description: Introduction: Coronary artery bypass grafting (CABG) is the most common cardiac surgical procedure. The prognosis of revascularization via CABG is determined by the patency of the used grafts, for which an intact endothelium is essential. The degree of ischemia-reperfusion injury (IRI), which occurs during the harvest and implantation of the grafts, is an important determinant of graft patency. Preconditioning with aspirin, a nonsteroidal anti-inflammatory drug has been shown to reduce the functional and molecular damage of arterial grafts in a rodent model. Studies have found that the zinc-aspirin complex may be able to exert an even better protective effect in pathological cardiovascular conditions. Thus, our aim was to characterize the protective effect of zinc-aspirin complex on free arterial grafts in a rodent model of revascularization. Methods: Donor Lewis rats were treated with either zinc-aspirin, aspirin, or placebo (n = 8) for 5 days, then the aortic arches were harvested and stored in cold preservation solution and implanted heterotopically in the abdominal cavity of the recipient rats, followed by 2 h of reperfusion. There was also a non-ischemia-reperfusion control group (n = 8). Functional measurements using organ bath and histomorphological changes using immunohistochemistry were analyzed. Results: The endothelium dependent maximal vasorelaxation was improved (non-transplanted control group: 82% ± 3%, transplanted control group: 14% ± 2%, aspirin group: 31% ± 4%, zinc-aspirin group: 52% ± 4%), the nitro-oxidative stress and cell apoptosis decreased, and significant endothelial protection was shown in the groups preconditioned with aspirin or zinc-aspirin. However, zinc-aspirin proved to be more effective in the reduction of IRI, than aspirin alone. Discussion: Preconditioning with zinc-aspirin could be a promising way to protect the function and structural integrity of free arterial grafts, thus improving the outcomes of CABG.
