description: Multimode bright squeezed vacuum is a non-classical state of light hosting a macroscopic photon number while offering promising capacity for encoding quantum information in its spectral degree of freedom. Here, we employ an accurate model for parametric downconversion in the high-gain regime and use nonlinear holography to design quantum correlations of bright squeezed vacuum in the frequency domain. We propose the design of quantum correlations over two-dimensional lattice geometries that are all-optically controlled, paving the way toward continuous-variable cluster state generation on an ultrafast timescale. Specifically, we investigate the generation of a square cluster state in the frequency domain and calculate its covariance matrix and the quantum nullifier uncertainties, that exhibit squeezing below the vacuum noise level.

description: Gamma-ray instrumentation for astronomical spectroscopy consists of multiple-interaction detectors in space combined with sophisticated post-processing of detector events on ground. Spectral signatures in the MeV regime originate from transitions in the nuclei of atoms (rather than in their electron shell). Nuclear transitions are stimulated by either radioactive decays or high-energy nuclear collisions such as with cosmic rays. Gamma-ray lines have been detected from radioactive isotopes produced in nuclear burning inside stars and supernovae, and from energetic-particle interactions in solar flares. 56Ni directly reflects the source of supernova light. The paucity of corresponding 44Ti gamma-ray line sources reflects the variety of dynamical conditions herein. 26Al and 60Fe are dispersed in interstellar space from massive-star nucleosynthesis over millions of years. Gamma-rays from their decay are measured in detail by gamma-ray telescopes, astrophysical interpretations reach from massive-star interiors to dynamical processes in the interstellar medium. Nuclear de-excitation gamma-ray lines have been found in solar-flare events, and convey information about energetic-particle production in these events, and their interaction in the solar atmosphere. The annihilation of positrons leads to another type of cosmic gamma-ray source. The characteristic annihilation gamma-rays at 511 keV have been measured long ago in solar flares, and now throughout the interstellar medium of our Milky Way galaxy. But now a puzzle has appeared, as a surprising predominance of the central bulge region was determined. This requires either new positron sources or transport processes not yet known to us. In this paper we discuss instrumentation and data processing for cosmic gamma-ray spectroscopy, and the astrophysical issues and insights from these measurements.

description: We compute the fully differential rate for the Higgs-boson decay $h\to Z\ell^+\ell^-$, with $Z\to\ell^{'+}\ell^{'-}$. For these processes we assume the most general matrix elements within an effective Lagrangian framework. The electroweak chiral Lagrangian we employ assumes minimal particle content and Standard Model gauge symmetries, but is otherwise completely general. We discuss how information on new physics in the decay form factors may be obtained that is inaccessible in the dilepton-mass spectrum integrated over angular variables. The form factors are related to the coefficients of the effective Lagrangian, which are used to estimate the potential size of new-physics effects.

description: We experimentally demonstrate broadband waveguide crossing arrays showing ultra low loss down to $0.04\,$dB/crossing ($0.9\%$), matching theory, and crosstalk suppression over $35\,$dB, in a CMOS-compatible geometry. The principle of operation is the tailored excitation of a low-loss spatial Bloch wave formed by matching the periodicity of the crossing array to the difference in propagation constants of the 1$^\text{st}$- and 3$^\text{rd}$-order TE-like modes of a multimode silicon waveguide. Radiative scattering at the crossing points acts like a periodic imaginary-permittivity perturbation that couples two supermodes, which results in imaginary (radiative) propagation-constant splitting and gives rise to a low-loss, unidirectional breathing Bloch wave. This type of crossing array provides a robust implementation of a key component enabling dense photonic integration.

description: Polarized NLTE radiative transfer in the presence of scattering in spectral lines and/or in continua may be cast in a so-called reduced form for six reduced components of the radiation field. In this formalism the six components of the reduced source function are angle-independent quantities. It thus reduces drastically the storage requirement of numerical codes. This approach encounters a fundamental problem when the medium is illuminated by a polarized incident radiation, because there is a priori no way of relating the known (and measurable) Stokes parameters of the incident radiation to boundary conditions for the reduced equations. The origin of this problem is that there is no unique way of deriving the radiation reduced components from its Stokes parameters (only the inverse operation is clearly defined). The method proposed here aims at enabling to work with arbitrary incident radiation field (polarized or unpolarized). In previous works an ad-hoc treatment of the boundary conditions, applying to cases where the incident radiation is unpolarized, has been used. In this note we show that it is possible to account for the incident radiation in a rigorous way, without any assumption on its properties, by expressing the radiation field as the sum of a directly transmitted radiation and of a so-called diffuse radiation. The diffuse radiation field obeys a transfer equation with no incident radiation that may be solved in the reduced form. The first scattering of the incident radiation introduces primary creation terms in the six components of the reduced source function. Once the reduced polarized transfer problem is solved for the diffuse radiation field, its Stokes parameters can be computed. We perform numerical computations of such cases, showing that the emergent line-polarization may be significantly affected by the polarization of the incident radiation.

description: The high-intensity proton beam of the TRIUMF 500 MeV cyclotron offers unique opportunities to produce rare isotopes by irradiating a variety of targets. In particular, the ISAC (Isotope Separation and ACceleration) facility provides the infrastructure to deliver customized rare ion beams for fundamental research in nuclear physics, astrophysics, material science, and nuclear medicine. A continuous effort is made to develop new radioactive ion beams (RIB) and improve their intensity or purity, properties that depend strongly on the type of target, operating conditions, the ion source, and beam transport efficiency. Yield data and theoretical production rates based on FLUKA and Geant4 simulations are collected in the TRIUMF Isotope Database, providing a valuable resource for RIB development and experiment planning. This paper introduces the newly upgraded TRIUMF Isotope Database and presents examples on how it's resources can be used to plan experiments and understand the origin of certain RIB. In particular we discuss the collection of 155Tb which is an important component of medical isotope research at TRIUMF.

First-principles thermodynamic screening approach to photo-catalytic water splitting with co-catalysts

description: We adapt the computational hydrogen electrode approach to explicitly account for photo-generated charges and use it to computationally screen for viable catalyst/co-catalyst combinations for photo-catalytic water splitting. The hole energy necessary to thermodynamically drive the reaction is employed as descriptor for the screening process. Using this protocol and hybrid-level density-functional theory we show that water oxidation on bare TiO2 surfaces is thermodynamically more complex than previously thought. This motivates a screening for suitable co-catalysts for this half-reaction, which we carry out for Au particles down to the non-scalable size regime. We find that almost all small Au clusters studied are better suited for water photo-oxidation than an extended Au(111) surface or bare TiO2 facets.

description: Robert Jervis of Columbia University offers a reformulation of the debate between realism and neoliberalism over the role of conflict and cooperation in international politics. Jervis argues that the disagreement between realists and neoliberals is not about the extent of conflict, but rather whether conflict is unnecessary given states' quest for security. He then explains the disagreement in the context of what realists and neoliberalists contend is required to facilitate greater international cooperation. Finally, Jervis seeks to elucidate the different perceptions of the two schools of thought on the importance of institutions.

description: Noncollinear antiferromagnets with novel magnetic orders, vanishingly small net magnetization and exotic spin related properties hold enormous promise for developing next-generation, transformative spintronic applications. A major ongoing research focus of this community is to explore, control, and harness unconventional magnetic phases of this emergent material system to deliver state-of-the-art functionalities for modern microelectronics. Here we report direct imaging of magnetic domains of polycrystalline Mn3Sn films, a prototypical noncollinear antiferromagnet, using nitrogen-vacancy-based single-spin scanning microscopy. Nanoscale evolution of local stray field patterns of Mn3Sn samples are systematically investigated in response to external driving forces, revealing the characteristic "heterogeneous" magnetic switching behaviors in polycrystalline textured Mn3Sn films. Our results contribute to a comprehensive understanding of inhomogeneous magnetic orders of noncollinear antiferromagnets, highlighting the potential of nitrogen-vacancy centers to study microscopic spin properties of a broad range of emergent condensed matter systems.

description: The radiation bystander effect is an important component of the overall biological response of tissues and organisms to ionizing radiation, but the signaling mechanisms between irradiated and non-irradiated bystander cells are not fully understood. In this study, we measured a time-series of gene expression after α-particle irradiation and applied the Feature Based Partitioning around medoids Algorithm (FBPA), a new clustering method suitable for sparse time series, to identify signaling modules that act in concert in the response to direct irradiation and bystander signaling. We compared our results with those of an alternate clustering method, Short Time series Expression Miner (STEM). While computational evaluations of both clustering results were similar, FBPA provided more biological insight. After irradiation, gene clusters were enriched for signal transduction, cell cycle/cell death and inflammation/immunity processes; but only FBPA separated clusters by function. In bystanders, gene clusters were enriched for cell communication/motility, signal transduction and inflammation processes; but biological functions did not separate as clearly with either clustering method as they did in irradiated samples. Network analysis confirmed p53 and NF-κB transcription factor-regulated gene clusters in irradiated and bystander cells and suggested novel regulators, such as KDM5B/JARID1B (lysine (K)-specific demethylase 5B) and HDACs (histone deacetylases), which could epigenetically coordinate gene expression after irradiation. In this study, we have shown that a new time series clustering method, FBPA, can provide new leads to the mechanisms regulating the dynamic cellular response to radiation. The findings implicate epigenetic control of gene expression in addition to transcription factor networks.

Measurement of neon in groundwaters for quantification of denitrification in aquifers
Publisher: name: GNS Science
Year: 2018

description:  Nitrate is the most pervasive contaminant in New Zealand’s groundwaters. Thus, understanding and managing nitrogen loads through New Zealand’s aquifers is vital for maintaining the quality of groundwaters and connected surface waters. Denitrification is a natural process that is mediated by the metabolism of aquifer microorganisms and by which dissolved nitrate is reduced eventually to nitrogen gas. However, the extent of denitrification occurring within New Zealand’s groundwater system is largely unknown, because there has historically been no straightforward, reliable and accurate technique to measure it. Calculation of the concentration of excess nitrogen in groundwaters is a promising technique to quantify the amounts of denitrification occurring in the groundwater system. The concentration of dissolved atmospheric nitrogen, according to the recharge conditions of the water, can be established by the measurement of two noble gases, such as neon and argon, which are part of the atmosphere. This enables differentiating the excess nitrogen gas produced via denitrification reactions from atmospherically derived dissolved nitrogen gas. This report details the development, validation and application of an analytical method to simultaneously measure dissolved neon, argon and nitrogen in groundwater. The method is compared to other denitrification proxies across three different regions in New Zealand, so that the potential for applying the newly developed procedure for quantification of excess N2 in groundwater can be assessed.

description: Background: The paper explores the potency of music activities and background music to support academic performance and behaviour of Slovak middle school pupils. It reviews developmental, social and emotional changes that children face during the period of preadolescence. School and education is connected with the formation of personality, thus school staff and parents need to pay attention to social and emotional well-being of pupils. The objective of the study is to investigate academic performance and behaviour of pupils (aged 10-11) before and after music intervention. Methods: The target research group consists of forty-four Slovak fifth graders from big urban, municipal middle school. Data were collected by evaluation of rating scale conducting teacher´s professional judgement about pupils they taught the four explored school subjects. Results: The study summarises the results of rating scale of teacher’s opinions of pupils’ academic performance and behaviour in the control and experimental groups (with and without music intervention). The results show the potency of music to support academic performance and improve behaviour of pupils.

description: We consider the general problem of fitting a parametric density model to discrete observations, taken to follow a non-homogeneous Poisson point process. This class of models is very common, and can be used to describe many astrophysical processes, including the distribution of protostars in molecular clouds. We give the expression for the likelihood of a given spatial density distribution of protostars and apply it to infer the most probable dependence of the protostellar surface density on the gas surface density. Finally, we apply this general technique to model the distribution of protostars in the Orion molecular cloud and robustly derive the local star formation scaling (Schmidt) law for a molecular cloud. We find that in this cloud the protostellar surface density, $Σ_\mathrm{YSO}$, is directly proportional to the square gas column density, here expressed as infrared extinction in the $K$-band, $A_K$: more precisely, $Σ_\mathrm{YSO} = (1.65 \pm 0.19) A_K^{(2.03 \pm 0.15)}$ stars pc$^{-2}$.

description: We calculate thermal conductivity and shear viscosity of nucleons in dense nuclear matter of neutron star cores in the non-relativistic Brueckner-Hartree-Fock framework. Nucleon-nucleon interaction is described by the Argonne v18 potential with addition of the Urbana IX effective three-body forces. We find that this three body force leads to decrease of the kinetic coefficients with respect to the two-body case. The results of calculations are compared with electron and muon transport coefficients as well as with the results of other authors.

description: We present the quasar luminosity function (LF) at $z = 7$, measured with 35 spectroscopically confirmed quasars at $6.55 < z < 7.15$. The sample of 22 quasars from the Subaru High-$z$ Exploration of Low-Luminosity Quasars (SHELLQs) project, combined with 13 brighter quasars in the literature, covers an unprecedentedly wide range of rest-frame ultraviolet magnitudes over $-28 < M_{1450} < -23$. We found that the binned LF flattens significantly toward the faint end populated by the SHELLQs quasars. A maximum likelihood fit to a double power-law model has a break magnitude $M^*_{1450} = -25.60^{+0.40}_{-0.30}$, a characteristic density $Φ^* = 1.35^{+0.47}_{-0.30}$ Gpc$^{-3}$ mag$^{-1}$, and a bright-end slope $β= -3.34^{+0.49}_{-0.57}$, when the faint-end slope is fixed to $α= -1.2$ as observed at $z \le 6$. The overall LF shape remains remarkably similar from $z = 4$ to $7$, while the amplitude decreases substantially toward higher redshifts, with a clear indication of an accelerating decline at $z \ge 6$. The estimated ionizing photon density, $10^{48.2 \pm 0.1}$ s$^{-1}$ Mpc$^{-3}$, is less than 1 % of the critical rate to keep the intergalactic medium ionized at $z = 7$, and thus indicates that quasars are not a major contributor to cosmic reionization.

description: Effective mitigation for N₂O emissions, now the third most important anthropogenic greenhouse gas and the largest remaining anthropogenic source of stratospheric ozone depleting substances, requires understanding of the sources and how they may increase this century. Here we update estimates and their uncertainties for current anthropogenic and natural N₂O emissions and for emissions scenarios to 2050. Although major uncertainties remain, ‘bottom-up’ inventories and‘top-down’ atmospheric modeling yield estimates that are in broad agreement. Global natural N₂O emissions are most likely between 10 and 12 Tg N2O-N yr˄−1. Net anthropogenic N₂O emissions are now about 5.3 Tg N₂O-N yr˄−1. Gross anthropogenic emissions by sector are 66% from agriculture, 15% from energy and transport sectors, 11% from biomass burning, and 8% from other sources. A decrease in natural emissions from tropical soils due to deforestation reduces gross anthropogenic emissions by about 14%. Business-as-usual emission scenarios project almost a doubling of anthropogenic N₂O emissions by 2050. In contrast, concerted mitigation scenarios project an average decline of 22% relative to 2005, which would lead to a near stabilization of atmospheric concentration of N₂O at about 350 ppb. The impact of growing demand for biofuels on future projections of N₂O emissions is highly uncertain; N₂O emissions from second and third generation biofuels could remain trivial or could become the most significant source to date. It will not be possible to completely eliminate anthropogenic N₂O emissions from agriculture, but better matching of crop N needs and N supply offers significant opportunities for emission reductions.

description: In this paper we study families of complex Hermite polynomials and construct deformed versions of them, using a $GL(2,\mathbb{C})$ transformation. This construction leads to the emergence of biorthogonal families of deformed complex Hermite polynomials, which we then study in the context of a two-dimensional model of noncommutative quantum mechanics.

THE BRAZILIAN CHORO: ITS HISTORY AND STRUCTURE
Creators: name: Magalhães, Marcelo G.M.
Publisher: name: ARS INTER CULTURAS
Year: 2018

description: This article examines the Brazilian musical genre known as Choro. Having discussed the history of Brazil, the genre is subsequently discussed within a broader context of Brazilian popular music. Many important aspects of Brazilian music related to Choro are consid- ered: (1) the influence of African culture and European music; (2) the role of classical composers like Heitor Villa-Lobos; and, (3) the influence of sacred music, opera and other popular musical types. There is also a detailed explanation of the connection between Choro and jazz, with special attention given to the structure of the music and the role of improvisation.

STYLISTIC TENDENCIES IN THE WORKS FOR ACCORDION BY UKRAINIAN COMPOSERS IN THE LATE 20th – EARLY 21st CENTURIES
Creators: name: Spodarenko, Victor
Publisher: name: ARS INTER CULTURAS
Year: 2018

description: The stylistic panorama of the 20th century music is notable for an aesthetic variety of works by different composers and compositional schools. This fact is corroborated by the ambiguity and plurality of musical cultures, made manifest by certain artistic trends and tendencies transpiring during the late 19 th and early 20 th centuries. As the century progressed, certain artistic tendencies underwent a transformation and evolved into other stylistic novelties. The works for the accordion by Ukrainian composers display folk-like influences and project an array of aesthetic approaches to the idea of musical personification. This is most clearly expressed in the way the composer: (1) borrows the material from folklore; (2) appeals to lyrical, psychological, expressive and figurative characteristics of work of art with the expression of the process-emotional nature of person’s “inner world”; (3) experiments with associative references such as, intonation, intonemas, and grief; (4) employs programmatic narrative; (5) uses epigraph and musical quotes; and (6) makes clear references to the genres and techniques of baroque and, occasionally, early classical music.

We Built This City: The Legality Of Community Benefit Agreements For Big Box Construction Under Title VII And The Equal Protection Clause

description: Community groups have begun to employ Community Benefit Agreements (CBAs) to combat the legacy of discrimination and segregation in the construction industry. The U.S. Government as well as state and city governments have implemented various plans since the 1960s to try to eradicate discrimination and segregation with a varied pattern of success. In light of the Supreme Court’s decisions in Adarand v. Pena and City of Richmond v. J.A. Croson, it is nearly impossible for a governmental entity to impose a hiring quota or percentage for minority groups. Therefore, without state intervention, the best way for communities to secure adequate opportunities may be to negotiate with the developers directly. This is where CBAs come in. CBAs, however, can take a couple of forms: private-private between private community groups and private developers or private-public between a private developer and some state actor. CBAs in each category may also have either geography-based hiring criteria, or race-based. This Note examines seven CBAs that fit under these different categories and measures them against the Supreme Court’s Title VII and Equal Protection jurisprudence. This Note ultimately seeks to suggest strategies for making CBAs successful against possible legal challenges.

Strong thermal leptogenesis and the absolute neutrino mass scale

description: We show that successful strong thermal leptogenesis, where the final asymmetry is independent of the initial conditions and in particular a large pre-existing asymmetry is efficiently washed-out, favours values of the lightest neutrino mass $m_1 \gtrsim 10\,{\rm meV}$ for normal ordering (NO) and $m_1 \gtrsim 3\,{\rm meV}$ for inverted ordering (IO) for models with orthogonal matrix entries respecting $|Ω_{ij}^2| \lesssim 2$. . We show analytically why lower values of $m_1$ require a high level of fine tuning in the seesaw formula and/or in the flavoured decay parameters (in the electronic for NO, in the muonic for IO). We also show how this constraint exists thanks to the measured values of the neutrino mixing angles and can be tighten by a future determination of the Dirac phase. Our analysis also allows to place more stringent constraint for a specific model or class of models, such as $SO(10)$-inspired models, and shows that some models cannot realise strong thermal leptogenesis for any value of $m_1$. A scatter plot analysis fully supports the analytical results. We also briefly discuss the interplay with absolute neutrino mass scale experiments concluding that they will be able in the coming years to either corner strong thermal leptogenesis or find positive signals pointing to a non-vanishing $m_1$. Since the constraint is much stronger for NO than for IO, it is very important that new data from planned neutrino oscillation experiments will be able to solve the ambiguity.
