description: In view of the global Food and Nutrition Security (FNS) challenges and the goals set in the Sustainable Development Goals (SDGs), the European Commission’s (EC) Directorate General for Research and Innovation (DG RTD) has established the FOOD 2030 policy framework with the objective to contribute, through research and innovation (R&I), to the transformation of European food systems to become more sustainable, resilient, responsible, diverse, inclusive and competitive. The aim of the EU Think Tank is to connect the EU-level with the global, national, regional and city levels. It serves as a strategic hub to work towards an integrated vision on EU food systems in a global context and the required transformation in R&I to deliver impact on the societal challenge of FNS. In this way, the EU Think Tank enables the EC to liaise with the emerging network and the lessons that FIT4FOOD2030 generates and act as a transformative network itself. It is also used as a sounding board that ensures a good connection with relevant developments, opportunities and needs on the European level and globally.
Large-Scale Bulk Motions Complicate the Hubble Diagram

description: We investigate the extent to which correlated distortions of the luminosity distance-redshift relation due to large-scale bulk flows limit the precision with which cosmological parameters can be measured. In particular, peculiar velocities of type 1a supernovae at low redshifts may prevent a sufficient calibration of the Hubble diagram necessary to measure the dark energy equation of state to better than 10%, and diminish the resolution of the equation of state time-derivative projected for planned surveys. We consider similar distortions of the angular-diameter distance, as well as the Hubble constant. We show that the measurement of correlations in the large-scale bulk flow at low redshifts using these distance indicators may be possible with a cumulative signal-to-noise ratio of order 7 in a survey of 300 type 1a supernovae spread over 20,000 square degrees.

Use of the revised Bayley scales of infant development with high-risk infants: exploration of changes in scores and relationships between risk variables and performance
Creators: name: Koseck, Karen
Publisher: name: University of British Columbia
Year: 2009

description: Cognitive and mental performance of 53 high-risk infants (34 prenatally exposed to drugs, and 19 born prematurely and/or with significant perinatal medical concerns) was measured using the Revised Bayley Scales of Infant Development (BSID-II) at less than 12 months, and at around 18 months of age. A retrospective chart review was used to collect BSID-II data and information on biological and environmental risk variables. The high-risk infants scored lower on the Mental and Motor Scales at both testing times compared to the norms (p<.01). Cognitive performance decreased over time if extrapolated scores were used in the analysis (p<.01). Infants born prematurely and/or with significant perinatal medical concerns had better overall motor performance compared to infants prenatally exposed to drugs (p<.01). Their motor scores increased, while the scores obtained by infants prenatally exposed to drugs decreased, regardless of whether or not extrapolated scores were used (p<.01). There were a few, isolated instances of linear relationships between risk variables, and cognitive and motor scores. The variance explained by regression equations tended to be low. Use of performance classifications versus extrapolated scores was the preferred method to include very low scores in analyses. Cumulative measures of environmental and biological risks could be better predictors of developmental outcomes than use of single variables.

description: The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges and gains expected in gravitational wave searches at frequencies above the LIGO/Virgo band, with a particular focus on Ultra High-Frequency Gravitational Waves (UHF-GWs), covering the MHz to GHz range. The absence of known astrophysical sources in this frequency range provides a unique opportunity to discover physics beyond the Standard Model operating both in the early and late Universe, and we highlight some of the most promising gravitational sources. We review several detector concepts which have been proposed to take up this challenge, and compare their expected sensitivity with the signal strength predicted in various models. This report is the summary of the workshop "Challenges and opportunities of high-frequency gravitational wave detection" held at ICTP Trieste, Italy in October 2019, that set up the stage for the recently launched Ultra-High-Frequency Gravitational Wave (UHF-GW) initiative.

description: We define the new description of the electromagnetic current to hold the current conservation in the momentum-dependent Dirac fields from the Ward Takahashi identity. To describe the momentum-dependence we solve the relativistic Hartree-Fock approximation by using the one-pion exchange. In addition we discuss on contribution from the one-pion exchange current and the core polarization. It is shown that this current can reduce the convection current in the isovector case, whose value has been too big due to the small effective mass in the usual relativistic Hartree approximation.

description: Stereotactic body radiation therapy allows for a precise and accurate dose delivery. Organ motion during treatment bears the risk of undetected high dose healthy tissue exposure. An organ very susceptible to high dose is the oesophagus. Its low contrast on CT and the oblong shape renders motion estimation difficult. We tackle this issue by modern algorithms to measure the oesophageal motion voxel-wise and to estimate motion related dosimetric impact. Oesophageal motion was measured using deformable image registration and 4DCT of 11 internal and 5 public datasets. Current clinical practice of contouring the organ on 3DCT was compared to timely resolved 4DCT contours. The dosimetric impact of the motion was estimated by analysing the trajectory of each voxel in the 4D dose distribution. Finally an organ motion model was built, allowing for easier patient-wise comparisons. Motion analysis showed mean absolute maximal motion amplitudes of 4.55 +/- 1.81 mm left-right, 5.29 +/- 2.67 mm anterior-posterior and 10.78 +/- 5.30 mm superior-inferior. Motion between the cohorts differed significantly. In around 50 % of the cases the dosimetric passing criteria was violated. Contours created on 3DCT did not cover 14 % of the organ for 50 % of the respiratory cycle and the 3D contour is around 38 % smaller than the union of all 4D contours. The motion model revealed that the maximal motion is not limited to the lower part of the organ. Our results showed motion amplitudes higher than most reported values in the literature and that motion is very heterogeneous across patients. Therefore, individual motion information should be considered in contouring and planning.

description: We prove the convex combination theorem for hyperbolic n-manifolds. Applications are given both in high dimensions and in 3 dimensions. One consequence is that given two geometrically finite subgroups of a discrete group of isometries of hyperbolic n-space, satisfying a natural condition on their parabolic subgroups, there are finite index subgroups which generate a subgroup that is an amalgamated free product. Constructions of infinite volume hyperbolic n-manifolds are described by gluing lower dimensional manifolds. It is shown that every slope on a cusp of a hyperbolic 3-manifold is a multiple immersed boundary slope. If a 3-manifold contains a maximal surface group not carried by an embedded surface then it contains the fundamental group of a book of I-bundles with more than two pages.

R-Matrix theory with level-dependent boundary condition parameters

description: I present a new formalism of the R-matrix theory where the formal parameters for the resonance energies and widths are identical to the observed values. By allowing the boundary condition parameters to vary from level to level, the freedom required to adjust the formal parameters for the pole positions to the observed values is obtained. The basis of the resulting theory becomes nonorthogonal, and I describe the procedure to construct a consistent R-matrix theory with such a nonorthogonal basis. And by adjusting the normalization of the states that form the basis, the formal parameters for the reduced decay widths also become the same as those observed, leaving no formal parameters that are different from the observed ones. A demonstration of the developed theory to the elastic 12C+p scattering data is presented.

description: We describe duality cascades and their infrared behavior for systems of D3-branes at singularities given by complex cones over del Pezzo surfaces (and related examples), in the presence of fractional branes. From the gauge field theory viewpoint, we show that D3-branes probing the infrared theory have a quantum deformed moduli space, given by a complex deformation of the initial geometry to a simpler one. This implies that for the dual supergravity viewpoint, the gauge theory strong infrared dynamics smoothes out the naked singularities of the recently constructed warped throat solutions with 3-form fluxes, describing the cascading RG flow of the gauge theory. This behavior thus generalizes the Klebanov-Strassler deformation of the conifold. We describe several explicit examples, including models with several scales of strong gauge dynamics. In the regime of widely separated scales, the dual supergravity solutions should correspond to throats with several radial regions with different exponential warp factors. These rich throat geometries are expected to have interesting applications in compactification and model building. Along our studies, we also construct explicit duality cascades for gauge theories with irrational R-charges, obtained from D-branes probing complex cones over dP1 and dP2.

description: We implement for the first time the simulated annealing method (SAM) to the problem of searching for the global minimum in the hyper-surface of the chi-square function which depends on the values of the parameters of a Skyrme type effective nucleon-nucleon interaction. We undertake a realistic case of fitting the values of the Skyrme parameters to an extensive set of experimental data on the ground state properties of many nuclei ranging from normal to exotic ones. The set of experimental data used in our fitting procedure includes the radii for the valence $1d_{5/2}$ and $1f_{7/2}$ neutron orbits in the $^{17}$O and $^{41}$Ca nuclei, respectively, and the breathing mode energies for several nuclei, in addition to the typically used data on binding energy, charge radii and spin-orbit splitting. We also include in the fit the critical density $ρ_{cr}$ and further constrain the values of the Skyrme parameters by requiring that (i) the quantity $P = 3ρ\frac{dS}{dρ}$, directly related to the slope of the symmetry energy $S$, must be positive for densities up to $3ρ_0$ (ii) the enhancement factor $κ$, associated with the isovector giant dipole resonance, should lie in the range of $0.1 - 0.5$ and (iii) the Landau parameter $G_0^\prime$ is positive at $ρ= ρ_0$. We provide simple but consistent schemes to account for the center of mass corrections to the binding energy and charge radii.

A stable isotopic analysis of syn-tectonic fluid regimes in the dogtooth, western, and main ranges of southeastern British Columbia
Creators: name: Knoop, Stuart R.
Publisher: name: University of British Columbia
Year: 2009

description: Stable isotope data from syn-kinematic veins, cataclasites, and wall rocks in the Dogtooth, Western, and Main Ranges of southeastern British Columbia document fluid migration across local and large-scale (100's of meters to 10's of kilometers) distances during Mesozoic contraction. Sampling was conducted across a ~30 km long western transect, which includes siliciclastic-dominated assemblages of the Dogtooth Range and carbonate units of the Western Ranges, and a ~5 km long eastern transect in carbonates and meta-pelites of the western Main Ranges. Syn-tectonic veins throughout the study area are comprised primarily of quartz and calcite and conform to three morphologies: i) laminated, bedding-parallel veins and syntaxial tension gashes, ii) boudinaged, cleavage-parallel veins, and iii) cataclasites and fault-parallel veins. In the Dogtooth Range, the oxygen isotopic composition of whole rock carbonates is ~5 % lower than accepted sedimentary protolith values. Vein calcite is generally depleted in ¹⁸O, whereas vein quartz is equally enriched and depleted compared with host rocks. Fluid-assisted isotopic exchange between siliciclastic and less-abundant carbonate assemblages across outcrops has lowered carbonate signatures and yielded quartz vein values that are more homogeneous than those of wall rocks. Hydrogen isotopes suggest that the fluids involved were metamorphic in origin with a possible meteoric component. In comparison, the Western Ranges exhibit an abrupt, mean δ¹⁸O increase of ~ 4.5 % and a trend of gradually heavier values with distance up-section and eastward from the Dogtooth Range. Neither variation in age nor mineral abundance can fully explain this phenomenon. Moreover, isotope and solvus thermometry indicate that veins were in thermal equilibrium with their host rocks (~300°C - 380°C). Hinterland-driven infiltration of low-61 80, low Xco2 fluid into the Western Ranges best explains this trend, and analytical modeling places time-integrated fluid fluxes at 104 - 105 mol H20/cm2 In the Main Ranges, oxygen values are more heterogeneous and reflect multiple fluid sources. Vein signatures as low as 6 %o indicate minor focussing of meteoric fluids downward into some fault zones. Variable vein quartz and wall rock carbonate values in other outcrops, in conjunction with a metamorphic hydrogen signature from vein chlorite, suggest that lower-81 80, metamorphic fluids were channeled upward under conditions of heterogeneous time-integrated fluid flux.

description: For a convex body $K\subset\mathbb{R}^d$ the mean distance $Δ(K)=\mathbb{E}|X_1-X_2|$ is the expected Euclidean distance of two independent and uniformly distributed random points $X_1,X_2\in K$. Optimal lower and upper bounds for ratio between $Δ(K)$ and the first intrinsic volume $V_1(K)$ of $K$ (normalized mean width) are derived and degenerate extremal cases are discussed. The argument relies on Riesz's rearrangement inequality and the solution of an optimization problem for powers of concave functions. The relation with results known from the existing literature is reviewed in detail.

description: We have grown NdBa2Cu3O7-d films under silver atomic flux by molecular beam epitaxy, which show a drastic improvement in microstructure and also crystallinity leading to 30 % enhancement in critical current density. The most remarkable point is that the final film is free from silver. The key to our process in achieving a silver-free film was the use of RF-activated oxygen that oxidizes silver, nonvolatile, to silver oxide, volatile at the deposition temperature. This process enables one to utilize the beneficial effects of silver in the growth of oxide films and at the same time ensures that the final film be free from silver, which is important for high-frequency applications. This method can be made use in the growth of thin films of other complex oxide materials.

description: Molecular robotics is challenging, so it seems best to keep it simple. We consider an abstract molecular robotics model based on simple folding instructions that execute asynchronously. Turning Machines are a simple 1D to 2D folding model, also easily generalisable to 2D to 3D folding. A Turning Machine starts out as a line of connected monomers in the discrete plane, each with an associated turning number. A monomer turns relative to its neighbours, executing a unit-distance translation that drags other monomers along with it, and through collective motion the initial set of monomers eventually folds into a programmed shape. We provide a suite of tools for reasoning about Turning Machines by fully characterising their ability to execute line rotations: executing an almost-full line rotation of $5π/3$ radians is possible, yet a full $2π$ rotation is impossible. Furthermore, line rotations up to $5π/3$ are executed efficiently, in $O(\log n)$ expected time in our continuous time Markov chain time model. We then show that such line-rotations represent a fundamental primitive in the model, by using them to efficiently and asynchronously fold shapes. In particular, arbitrarily large zig-zag-rastered squares and zig-zag paths are foldable, as are $y$-monotone shapes albeit with error (bounded by perimeter length). Finally, we give shapes that despite having paths that traverse all their points, are in fact impossible to fold, as well as techniques for folding certain classes of (scaled) shapes without error. Our approach relies on careful geometric-based analyses of the feats possible and impossible by a very simple robotic system, and pushes conceptional hardness towards mathematical analysis and away from molecular implementation.

description: It is common, in both theoretical and experimental studies, to separately discuss quark and gluon jets. However, even at parton level, widely-used jet algorithms fail to provide an infrared safe way of making this distinction. We examine the origin of the problem, and propose a solution in terms of a new "flavour-kt" algorithm. As well as being of conceptual interest this can be a powerful tool when combining fixed-order calculations with multi-jet resummations and parton showers. It also has applications to studies of heavy-quark jets.

description: Our situation as occupants of the Milky Way (MW) Galaxy, bombarded by the Sagittarius dwarf galaxy, provides an intimate view of physical processes that can lead to the dynamical heating of a galactic disc. While this evolution is instigated by Sagittarius, it is also driven by the intertwined influences of the dark matter halo and the disc itself. We analyse an N-body simulation following a Sagittarius-like galaxy interacting with a MW-like host to disentangle these different influences during the stages of a minor merger. The accelerations in the disc plane from each component are calculated for each snapshot in the simulation, and then decomposed into Fourier series on annuli. The analysis maps quantify and compare the scales of the individual contributions over space and through time: (i) accelerations due to the satellite are only important around disc passages; (ii) the influence around these passages is enhanced and extended by the distortion of the dark matter halo; (iii) the interaction drives disc asymmetries within and perpendicular to the plane and the self-gravity of these distortions increase in importance with time eventually leading to the formation of a bar. These results have interesting implications for identifying different influences within our own Galaxy. Currently, Sagittarius is close enough to a plane crossing to search for localized signatures of its effect at intermediate radii, the distortion of the MW's dark matter halo should leave its imprint in the outer disc and the disc's own self-consistent response is sculpting the intermediate and inner disc.

description: Nucleon form factors play an especially important role in studying the dynamics of nucleons and explicit structure of the wave functions at arbitrary nucleon velocity. The purpose of the paper is to explain theoretically all four nucleon form factors measured experimentally in the cross section measurements (by the Rosenbluth method), yielding almost equal normalized form factors $G^p_E,G^p_M,G^n_M$, as well as in the polarization transfer experiments, where a strongly decreasing proton electric form factor has been discovered. It is shown, using relativistic hyperspherical formalism, that the nucleon wave functions in the lowest approximation provide almost equal normalized form factors as seen in the Rosenbluth cross sections, but in the higher components they contain a large admixture of the quark orbital momenta, which strongly decreases $G^p_E$ and this effect is possibly detected in the polarization transfer method (not seen in the classical cross section experiments). Moreover, the same admixture of the higher components explains the small positive form factor $G^n_E$. The resulting form factors, $G^p_M(Q),G^p_E(Q),G^n_M(Q)$ are calculated up to $Q^2\approx 10$ GeV$^2$, using the standard and the Lorentz contracted wave functions and shown to be in reasonable agreement with experimental data.

A Partial Equilibrium Approach of Modeling Vertical Linkages in the U.S. Flat Rolled Steel Market

Publisher: name: Unknown
Year: 2005
Subjects: Industrial Organization

description: This paper models linkages between upstream and downstream goods in the U.S. market for flat-rolled steel. These vertical linkages are important to account for when estimating the impact of trade restrictions on imports of flat rolled steel because some types of flat rolled steel are predominately used to produce other types of flat rolled steel and in some cases also make up a large share of their production costs. Previous research has modeled the linkages between upstream and downstream goods with CGE models and vertically linked partial equilibrium models. Drawing upon this literature, this paper builds a vertically linked version of the CES COMPAS model that incorporates vertical linkages as constant cross price elasticities in both downstream supply functions and upstream factor demand functions. Compared to estimates from the CES COMPAS without vertical linkages, introduction of a trade restriction increases demand for upstream goods and decreases supply of downstream goods, increasing prices of both upstream and downstream goods, while increasing shipments of upstream goods and decreasing shipments of downstream goods. In estimating the impact of the safeguard measures imposed on the flat rolled steel market, accounting for the vertical linkages is most important when estimating the impact on domestically produced slab since all downstream products produced from slab were subject to the safeguard tariffs.

description: In this paper, the 2-state decomposed-type quantum walk (DQW) on a line is introduced as an extension of the 2-state quantum walk (QW). The time evolution of the DQW is defined with two different matrices, one is assigned to a real component, and the other is assigned to an imaginary component of the quantum state. Unlike the ordinary 2-state QWs, localization and the spreading phenomenon can coincide in DQWs. Additionally, a DQW can always be converted to the corresponding 4-state QW with identical probability measures. In other words, a class of 4-state QWs can be realized by DQWs with 2 states. In this work, we reveal that there is a 2-state DQW corresponding to the 4-state Grover walk. Then, we derive the weak limit theorem of the class of DQWs corresponding to 4-state QWs which can be regarded as the generalized Grover walks.

description: The global economic effects of eliminating certain significant categories of nontariff measures (NTMs) are estimated in a CGE context. As a first step, a database of institutional information identifying alleged instances of NTMs for particular products and countries is constructed based on WTO, U.S. Government, and EU sources, and compared with the UNCTAD policy inventory. This database is then concorded to a GTAP-feasible multiregion, multisector aggregation. Retail price data from the EIU CityData database, similarly concorded, are analyzed econometrically, taking into account systematic deviations from purchasing-power parity, to determine whether and to what extent the presence of alleged NTMs is associated with significantly higher prices. The estimated price effects are then used to calibrate a CGE simulation in order to obtain simulation estimates of trade and welfare effects of their removal, which can be disaggregated. Removal of the categories of NTMs under consideration yields global gains on the order of $90 billion. These gains arise notably from liberalization by Japan and the European Union by region, and from liberalization of apparel and machinery/equipment by sector.

description: Many improvements have been proposed for the basic gravity model specification, most of which are confirmed by standard statistical tests due to the large number of observations often used to estimate such models. We use Monte Carlo experiments to examine situations in which features of models may be found statistically significant (or insignificant) when it is known ex ante that they are absent (or present) in the underlying data process. Erroneous assumptions about the presence or absence of lagged dependent variables, fixed effects, free-trade associations and customs unions are shown to introduce economically important bias in estimates of the coefficients of interest, and in some cases to be confirmed spuriously. Policy effects, such as for free trade associations and currency unions, can also be confirmed spuriously when they do not exist in the data-generating process.
Theoretical Study of Sodium and Potassium Resonance Lines Pressure Broadened by Helium Atoms

description: We perform fully quantum mechanical calculations in the binary approximation of the emission and absorption profiles of the sodium $3s$-$3p$ and potassium $4s$-$4p$ resonance lines under the influence of a helium perturbing gas. We use carefully constructed potential energy surfaces and transition dipole moments to compute the emission and absorption coefficients at temperatures from 158 to 3000 K. Contributions from quasi-bound states are included. The resulting red and blue wing profiles agree well with previous theoretical calculations and with experimental measurements.

Linearization and H\" older Continuity for Nonautonomous Systems

description: We consider a nonautonomous system \[ \dot x=A(t)x+f(t,x,y),\quad \dot y = g(t,y)\] and give conditions under which there is a transformation of the form $H(t,x,y)=(x+h(t,x,y),y)$ taking its solutions onto the solutions of the partially linearized system \[ \dot x=A(t)x,\quad \dot y = g(t,y).\] Shi and Xiong \cite{SX} proved a special case where $g(t,y)$ was a linear function of $y$ and $\dot x=A(t)x$ had an exponential dichotomy. Our assumptions on $A$ and $f$ are of the general form considered by Reinfelds and Steinberga \cite{RS}, which include many of the generalizations of Palmer's theorem proved by other authors. Inspired by the work of Shi and Xiong, we also prove H\" older continuity of $H$ and its inverse in $x$ and $y$. Again the proofs are given in the context of Reinfelds and Steinberga but we show what the results reduce to when $\dot x=A(t)x$ is assumed to have an exponential dichotomy. The paper is concluded with the discrete version of the results.

description: In this article, we give a complete characterization of all the unitary transformations that can be synthesized in a given time for a system of coupled spin-1/2 in presence of general time varying coupling tensor. Our treatment is quite general and our results help to characterize the reachable set at all times for a class of bilinear control systems with time varying drift and unbounded control amplitude. These results are of fundamental interest in geometric control theory and have applications to control of coupled spins in solid state NMR spectroscopy.

Multi-quantum eigenstates of a linear chain of coupled qubits

description: We present a technique to identify exact analytic expressions for the multi-quantum eigenstates of a linear chain of coupled qubits. A choice of Hilbert subspaces is described which allows an exact solution of the stationary Schrödinger equation without imposing periodic boundary conditions and without neglecting end effects, fully including the dipole-dipole nearest-neighbor interaction between the atoms. The treatment is valid for an arbitrary coherent excitation in the atomic system, any number of atoms, any size of the chain relative to the resonant wavelength and arbitrary initial conditions of the atomic system. The procedure we develop is general enough to be adopted for the study of excitation in an arbitrary array of atoms including spin chains and one-dimensional Bose-Einstein condensates.

The role of the chorus in Sophocles’ Ajax and Antigone
Creators: name: Martin, Lindsay Geddes
Publisher: name: University of British Columbia
Year: 2009

description: The Chorus in the Ajax are both soldiers and sailors, completely dependent on their leader, Ajax, and strongly affected by developments in the action. They provide commentary on Ajax directly, by ascribing various adjectives to him, and by contrasting his former and present states, and indirectly, by remaining loyal to him. They are used to express various emotions, such as anxiety and distress, melancholy and despondency, excitement and joy, grief and mourning, and they generate tension and a sense of danger during much of the play. The respect and concern they show toward Tecmessa, their steadfast support of Ajax, and their involvement in a dangerous situation not of their making make them a sympathetic Chorus. Their description of Ajax's grieving mother in the first stasimon, their illogical excitement in the second stasimon, and their attempts at mediation between Teucer and the Atreidai do not emanate from their personality but exist for dramatic purposes. Although they do not unify the two parts of the play, they mold our assessment of Ajax. The Chorus in the Antigone are pious, elderly men, who embody community wisdom and show deference to power. Their support of Creon, however, is not whole-hearted, but because they fear him, they do not speak candidly. Toward Antigone, they are both sympathetic and critical, but differences of age and gender prevent a close association with her. In their songs they introduce or develop ideas which often impart a certain sense of disjunction, because the connection to the previous episode is not immediately apparent. Nevertheless, the ideas are relevant to important themes in the play. The Chorus also convey various emotions, such as joy and thanksgiving, marvel and horror, pessimism (about human powerlessness in relation to the gods), apprehension and (false) hope. Their lyrics are suggestive of secondary meanings, which are often applicable to Creon, but of which they are not fully cognizant. Their relationship to Antigone creates interest because we wonder why, other than their fear of Creon, they are not more supportive of her.
