description: We address the applicability of quantum key distribution with continuous-variable coherent and squeezed states over long-distance satellite-based links, considering low Earth orbits and taking into account strong varying channel attenuation, atmospheric turbulence and finite data ensemble size effects. We obtain tight security bounds on the untrusted excess noise on the channel output, which suggest that substantial efforts aimed at setup stabilization and reduction of noise and loss are required, or the protocols can be realistically implemented over satellite links once either individual or passive collective attacks are assumed. Furthermore, splitting the satellite pass into discrete segments and extracting the key from each rather than from the overall single pass allows one to effectively improve robustness against the untrusted channel noise and establish a secure key under active collective attacks. We show that feasible amounts of optimized signal squeezing can substantially improve the applicability of the protocols allowing for lower system clock rates and aperture sizes and resulting in higher robustness against channel attenuation and noise compared to the coherent-state protocol

description: Mass events represent one of the most challenging scenarios for mobile networks because, although their date and time are usually known in advance, the actual demand for resources is difficult to predict due to its dependency on many different factors. Based on data provided by a major European carrier during mass events in a football stadium comprising up to 30.000 people, 16 base station sectors and $1$Km$^2$ area, we performed a data-driven analysis of the radio access network infrastructure dynamics during such events. Given the insights obtained from the analysis, we developed ARENA, a model-free deep learning Radio Access Network (RAN) capacity forecasting solution that, taking as input past network monitoring data and events context information, provides guidance to mobile operators on the expected RAN capacity needed during a future event. Our results, validated against real events contained in the dataset, illustrate the effectiveness of our proposed solution.

description: Using XMM Newton data, we investigate the nature of the X-ray emission in the radio relic 1253+275 in the Coma cluster. We determine the conditions of the cluster gas to check current models of relic formation, and we set constraints on the intracluster magnetic field. Both imaging and spectral analysis are performed, and the X-ray emission is compared with the radio emission. We found that the emission is of thermal origin and is connected to the sub-group around NGC 4839. The best-fit gas temperature in the region of the relic and in its vicinity is in the range 2.8 - 4.0 keV, comparable to the temperature of the NGC 4839 sub-group. We do not detect any high temperature gas, resulting from a possible shock in the region of the Coma relic. We therefore suggest that the main source of energy for particles radiating in the radio relic is likely to be turbulence. From the X-ray data, we can also set a flux upper limit of 3.2 x 10e-13 erg/cm^2 s, in the 0.3 - 10 keV energy range, to the non-thermal emission in the relic region. This leads to a magnetic field B > 1.05 microG.

BAT99 126: A multiple Wolf-Rayet system in the Large Magellanic Cloud with a massive near-contact binary

description: BAT99 126 is a multiple system in the Large Magellanic Cloud containing a Wolf-Rayet (WR) star, which has a reported spectroscopic (orbital) period of 25.5 days and a photometric (orbital) period of 1.55 days, and hence is potentially one of the shortest WR binaries known to date. Such short-period binary systems containing a WR star in low-metallicity environments are prime candidate progenitors of black-hole (BH) mergers. By thoroughly analysing the spectroscopic and photometric data, we aim to establish the true multiplicity of BAT99 126, characterise the orbit(s) of the system, measure the physical properties of its individual components, and determine the overall evolutionary status of the system. Using newly acquired high resolution spectra, we measured radial velocities and performed a spectral analysis of the individual components. We estimated the age of the system and derived an evolutionary scenario for the 1.55-day system. BAT99 126 comprises at least four components. The 1.55-day photometric signal originates in an eclipsing O+O binary of spectral types O4 V and O6.5 V, and masses of 36+/-5 MSun and 15+/-2 MSun, respectively. For the WR star, we derived a spectral type WN2.5-3 and reject the previously reported 25.5-d period. We find evidence in the composite spectra of a fourth component, a B1 V star, which shows radial velocity variation. The configurations of the B-type star, WR star, and possible additional undetected components remain unknown. We estimated the age of the system to be 4.2 Myr. The O+O binary likely went through a phase of conservative mass transfer and is currently a near-contact system. We show that BAT99 126 is a multiple - quadruple or higher-order - system with a total initial mass > 160 MSun. The 1.55-day O+O binary most likely will not evolve towards a BH+BH merger, but instead will merge before the components collapse to BHs.

description: The detection of almost 100% linearly polarized emission from the fast radio burst source FRB 121102 implies coherent emission of relativistic electrons moving in perpendicular to the ambient magnetic field. The origin of such a particle distribution is very intriguing. Given that FRB 121102 is likely driven by a neutron star, we explored orbits of charged particles trapped in a dipole magnetic field (the Störmer problem). Most previous studies focused on particles with relatively low energies so that the guiding center approximation may be applied. High energy particles usually have chaotic orbits except those on a periodic orbit or near stable periodic orbits. Via evaluation of the maximum Lyapunov exponent of orbits of particles launched from the equatorial plane with an axial velocity (the angular velocity sets the length and energy scales of the system), we found prominent regions of quasi-periodic orbits around stable periodic orbits in the equatorial plane at high-energies. Particles in these orbits oscillate around the equatorial plane and their radial distance from the dipole can vary by a factor of/,2. Relativistic electrons in such orbits may be responsible for the almost 100% polarized emission from FRB 121102.

description: Inseparability criteria for continuous and discrete bipartite quantum states based on moments of annihilation and creation operators are studied by developing the idea of Shchukin-Vogel criterion [Phys. Rev. Lett. {\bf 95}, 230502 (2005)]. If a state is separable, then the corresponding matrix of moments is separable too. Thus, we derive generalized criteria, based on the separability properties of the matrix of moments, are thus derived. In particular, a new criterion based on realignment of moments in the matrix is proposed as an analogue of the standard realignment criterion for density matrices. Other inseparability inequalities are obtained by applying positive maps to the matrix of moments. Usefulness of the Shchukin-Vogel criterion to describe bipartite-entanglement of more than two modes is demonstrated: We obtain some previously known three-mode inseparability criteria originally derived from the Cauchy-Schwarz inequality, and we introduce new ones.

description: It is shown that not all linear electromagnetic constitutive laws will define almost-complex structure on the bundle of 2-forms on the spacetime manifold when composed with the Poincare duality isomorphism, but only a restricted class of them that includes linear spatially isotropic and some bi-isotropic laws. Although this does not trivialize the formulation of the basic equations equations of pre-metric electromagnetism, it does affect their reduction to metric electromagnetism by its effect on the types of media that are reducible, and possibly its effect on the way that such media support the propagation of electromagnetic waves.

description: This paper proposes a lexicographic Deep Reinforcement Learning (DeepRL)-based approach to chance-constrained Markov Decision Processes, in which the controller seeks to ensure that the probability of satisfying the constraint is above a given threshold. Standard DeepRL approaches require i) the constraints to be included as additional weighted terms in the cost function, in a multi-objective fashion, and ii) the tuning of the introduced weights during the training phase of the Deep Neural Network (DNN) according to the probability thresholds. The proposed approach, instead, requires to separately train one constraint-free DNN and one DNN associated to each constraint and then, at each time-step, to select which DNN to use depending on the system observed state. The presented solution does not require any hyper-parameter tuning besides the standard DNN ones, even if the probability thresholds changes. A lexicographic version of the well-known DeepRL algorithm DQN is also proposed and validated via simulations.

We compute the pair formation temperature and superfluid transition temperature $T_c$ and superfluid density in a manner consistent with the standard ground state equations, and thereby present a complete phase diagram. Finite temperature stabilizes superfluidity, as manifested by two solutions for $T_c$, or by low $T$ instabilities. At unitarity the polarized state is an ``intermediate temperature superfluid".

This extends our previous calculation from the quenched to the unquenched theory. The resulting spectral correlation function in the $ε$-regime provides here, too, a new and efficient way to measure $F_π$ on the lattice. We test the method in a hybrid Monte Carlo simulation of the theory with two staggered quarks.

description: Recent discovery of persistent revivals in quantum simulators based on Rydberg atoms have pointed to the existence of a new type of dynamical behavior that challenged the conventional paradigms of integrability and thermalization. This novel collective effect has been named quantum many-body scars by analogy with weak ergodicity breaking of a single particle inside a stadium billiard. In this overview, we provide a pedagogical introduction to quantum many-body scars and highlight the newly emerged connections with the semiclassical quantization of many-body systems. We discuss the relation between scars and more general routes towards weak violations of ergodicity due to "embedded" algebras and non-thermal eigenstates, and highlight possible applications of scars in quantum technology.

description: This paper reviews the linearized path integral approach for computing time dependent properties of systems that can be approximated using a mixed quantum-classical description. This approach is applied to studying vibrational pure dephasing of ground state molecular iodine in a rare gas matrix. The Feynman-Kleinert optimized harmonic approximation for the full system density operator is used to sample initial conditions for the bath degrees of freedom. This extremely efficient approach is compared with alternative initial condition sampling techniques at low temperatures where classical initial condition sampling yields dephasing rates that are nearly an order of magnitude too slow compared with quantum initial condition sampling and experimental results.

description: We present the detailed spectroscopic study of V565 Mon pre-main-sequence star, which is the illuminating star of Parsamian 17 cometary nebula. Observations were performed with 2.6 m telescope in Byurakan Astrophysical Observatory in 15 February 2018. Radial velocities and equivalent widths of the most prominent lines of V565 Mon are presented. We built the spectral energy distribution and estimated the main parameters of the star, for example obtained bolometric luminosity of V565 Mon is $L_{V565}\approx 130L_{\odot} $ . Considering all features of V565 Mon we came to conclusion that this young intermediate-mass star can belongs to some intermediate class between T Tau and HAeBe stars. Very unusual for a young star is the presence of strong absorption Ba II lines in the spectrum. Possible explanations on this issue are discussed. Hence, we think that V565 Mon is a unique example, which can help to understand some open questions in nucleosynthesis problem in young stars.

description: The study of topological band structures have sparked prominent research interest the past decade, culminating in the recent formulation of rather prolific classification schemes that encapsulate a large fraction of phases and features. Within this context we recently reported on a class of unexplored topological structures that thrive on the concept of {\it sub-dimensional topology}. Although such phases have trivial indicators and band representations when evaluated over the complete Brillouin zone, they have stable or fragile topologies within sub-dimensional spaces, such as planes or lines. This perspective does not just refine classification pursuits, but can result in observable features in the full dimensional sense. In three spatial dimensions (3D), for example, sub-dimensional topologies can be characterized by non-trivial planes, having general topological invariants, that are compensated by Weyl nodes away from these planes. As a result, such phases have 3D stable characteristics such as Weyl nodes, Fermi arcs and edge states that can be systematically predicted by sub-dimensional analysis. Within this work we further elaborate on these concepts. We present refined representation counting schemes and address distinctive bulk-boundary effects, that include momentum depended (higher order) edge states that have a signature dependence on the perpendicular momentum. As such, we hope that these insights might spur on new activities to further deepen the understanding of these unexplored phases.

Deep Learning methodologies and more specifically deep convolutional neural networks (CNN) are employed in the new reconstruction method, which is referred to as "CNN Reconstruction - CNNR". For training of the CNNR Projection data from software phantoms were used. For evaluation of the efficacy of the CNNR method, both software and hardware phantoms were used. The resulting tomographic images are compared to those produced by filtered back projection (FBP) [1], the "Maximum Likelihood Expectation Maximization" (MLEM) [1] and ordered subset expectation maximization (OSEM) [2].

Creators: name: Günther, Annika

description: Diese Arbeit behandelt das Non-Refoulement Prinzip und wie es im Hinblick auf klimabedingte Migration anwendbar ist. Zunächst wird ein Überblick über die rechtlichen Grundlagen des Non-Refoulement Prinzips gegeben, wobei auch die Zugehörigkeit zum Völkergewohnheitsrecht und die jus cogens Natur des Prinzips beleuchtet werden. Der zentrale Fokus dieser Arbeit liegt jedoch auf der Auseinandersetzung mit bereits existierender Rechtsprechung zum Non-Refoulement Prinzip, bei der Fälle des UN-Menschenrechtsausschusses, des Europäischen Gerichtshofs für Menschenrechte, des Gerichtshof der Europäischen Union und nationalen Gerichten herangezogen werden. Hierbei werden Kriterien und Anhaltspunkte analysiert, die sich auf Fälle übertragen lassen könnten, bei denen Klimabedingungen im Zielstaat die Anwendung des Non-Refoulement Prinzips hervorrufen könnten. Dabei kristallisiert sich heraus, dass vor allem die Komplexität des Klimawandels und die nicht abschließend geklärte menschliche Verantwortung Probleme bereiten bisherige Rechtsprechung auf klimabedingte Migration anzuwenden. Dies lässt schließlich erkennen, dass auch alternative Lösungsvorschläge beachtet werden müssen. Dabei wird neben der präferierten Lösung auf UN-Ebene deutlich, dass der Komplexität des Themas nur eine Kombination und ein Zusammenspiel aus Menschenrechten, Migrationsrecht und Umweltrecht gerecht werden kann.

description: The two-character level-1 WZW models corresponding to Lie algebras in the Cvitanović-Deligne series $A_1,A_2,G_2,D_4,F_4,E_6,E_7$ have been argued to form coset pairs with respect to the meromorphic $E_{8,1}$ CFT. Evidence for this has taken the form of holomorphic bilinear relations between the characters. We propose that suitable 4-point functions of primaries in these models also obey bilinear relations that combine them into current correlators for $E_{8,1}$, and provide strong evidence that these relations hold in each case. Different cases work out due to special identities involving tensor invariants of the algebra or hypergeometric functions. In particular these results verify previous calculations of correlators for exceptional WZW models, which have rather subtle features. We also find evidence that the intermediate vertex operator algebras A$_{0.5}$ and E$_{7.5}$, as well as the three-character A$_{4,1}$ theory, also appear to satisfy the novel coset relation.

description: At the Relativistic Heavy Ion Collider (RHIC) collisions of heavy ions at nucleon-nucleon energies of 200 GeV appear to have created a new form of matter thought to be a deconfined state of the partons that ordinarily are bound in nucleons.We discuss the evidence that a thermalized partonic medium, usually called a Quark Gluon Plasma (QGP), has been produced. Then we discuss the effect of this high-density medium on the production of jets and their pair correlations. Next we look at direct photons as a clean electro-magnetic probe to constrain the initial hard scatterings. Finally we review the developing picture for the effect of this medium on the production of open heavy quarks and on the screening by the QGP of heavy-quark bound states.

description: Coexisting ferromagnetic and antiferromagnetic phases over a range of temperature as well as magnetic field have been reported in many materials of current interest, showing disorder-broadened 1st order transitions. Anomalous history effects observed in magnetization and resistivity are being explained invoking the concepts of kinetic arrest akin to glass transitions. From magnetization measurements traversing novel paths in field-temperature space, we obtain the intriguing result that the regions of the sample which can be supercooled to lower temperatures undergo kinetic-arrest at higher temperatures, and vice versa. Our results are for two diverse systems viz. the inter-metallic doped CeFe$_2$ which has an antiferromagnetic ground state, and the oxide La-Pr-Ca-Mn-O which has a ferromagnetic ground state, indicating the possible universality of this effect of disorder on the widely encountered phenomenon of glass-like arrest of kinetics.

description: Methods for constructing synthetic multidimensional electron hole equilibria without using particle simulation are investigated. Previous approaches have various limitations and approximations that make them unsuitable within the context of expected velocity diffusion near the trapped-passing boundary. An adjustable model of the distribution function is introduced that avoids unphysical singularities there, and yet is sufficiently tractable analytically to enable prescription of the potential spatial profiles. It is shown why simple models of the charge density as being a function only of potential cannot give solitary multidimensional electron holes, in contradiction of prior suppositions. Fully self-consistent axisymmetric electron holes in the drift-kinetic limit of electron motion (negligible gyro-radius) are constructed and their properties relevant to observational interpretation and finite-gyro-radius theory are discussed.

title: A surgery approach to abelian quotients of the level 2 congruence group and the Torelli group
Creators: name: Lewis, Tudur
Publisher: name: University of Glasgow
Year: 2024

description: We provide a unified framework for studying two families of maps: the Birman–Craggs maps of the Torelli group, and Sato’s maps of the level 2 congruence subgroup of the mapping class group. Our framework gives new, elementary proofs that both families of maps are homomorphisms, gives a direct method for evaluating these maps on Dehn twists, and relates the two families when restricted to the Torelli group. Our methods involve 3-manifold techniques that do not depend on results in 4–manifold theory as in the original constructions, giving an answer to a question of Dennis Johnson. We also find a relation between an extension of the Birman–Craggs maps to the level 2 congruence subgroup, and Meyer’s signature cocycle.

description: In the advent of large scale surveys, individually modelling strong-gravitational lenses and their counterpart time-delays in order to precisely measure $H_0$ will become computationally expensive, and highly complex. A complimentary approach is to study the cumulative distribution function (CDF) of time-delays where the global population of lenses is modelled along with $H_0$. In this paper we use a suite of hydro-dynamical simulations to estimate the CDF of time-delays from doubly-imaged quasars for a realistic distribution of lenses. We find that the CDFs exhibit large amounts of halo-halo variance, regulated by the density profile inner slope and the total mass within $5$kpc. With the objective of fitting to data, we compress the CDFs using Principal Component Analysis and fit a Gaussian Processes Regressor consisting of three physical features: the redshift of the lens, $z_{\rm L}$; the power law index of the halo, $α$, and the mass within $5$kpc, plus four cosmological features. Assuming a flat Universe, we fit our model to 27 doubly-imaged quasars finding $H_0=71^{+2}_{-3}$km/s/Mpc, $z_{\rm L} = 0.36_{-0.09}^{+0.2} $, $α=-1.8_{-0.1}^{+0.1}$, $\log(M(<5$kpc$)/M_\odot)=11.1_{-0.1}^{+0.1} $, $Ω_{\rm M} = 0.3_{-0.04}^{+0.04} $ and $Ω_{\rm Λ}=0.7_{-0.04}^{+0.04}$. We compare our estimates of $z_{\rm L}$ and $\log(M(<5$kpc$)/M_\odot)$ to the data and find that within the sensitivity of the data, they are not systematically biased. We generate mock CDFs and find with that the Vera Rubin Observatory (VRO) could measure $σ/H_0$ to $<3\%$, limited by the precision of the model. If we are to exploit fully VRO, we require simulations that sample a larger proportion of the lens population, with a variety of feedback models, exploring all possible systematics.

Subjects: subject: Transportation Engineering

description: Average speed is an essential input to the air quality analysis model MOBILE6 for emission factor calculation. Traditionally, speed is obtained from travel demand models. However, such models are not usually calibrated to speeds. Furthermore, for rural areas where such models are not available, there has not been a reliable method for estimating speed.  In this study, a procedure was developed based on the Highway Economic Requirement System (HERS) speed model to estimate average speed using as input various data such as roadway characteristics and traffic conditions. This procedure was coded in MS Excel macro and can be attached to a workbook that contains the roadway inventory data in the HPMS format.  The comparison between the measured speeds and those estimated by the model demonstrated the strong performance of the model. The data availability and accuracy issue during the implementation stage was discussed.

description: Innovative construction and reconstruction methods provide the opportunity to significantly reduce the time of roadway projects while maintaining the necessary quality of workmanship. The need for these “rapid” methods stems from the increase in traffic on Kentucky roadways coupled with the rise in conventional road and bridge construction methods. Conventional construction methods cannot maintain the demand for progress necessitated by the future needs of the Kentucky Transportation Cabinet, especially the current philosophy of “Get In, Get Out, and Stay Out.” This research documents a series of case studies that examined past projects which used innovative rapid construction methods. This document also includes a decision making model based on road user costs and various project parameters which can broaden the Cabinet’s awareness of the project options available for each venture.

description: We present the first results of the VIsible Multiobject Spectrograph (VIMOS) ESO/GOODS program of spectroscopy of faint galaxies in the Chandra Deep Field South (CDF-S). The program complements the FORS2 ESO/GOODS campaign. 3312 spectra have been obtained in service mode with VIMOS at the ESO/VLT UT3. The VIMOS LR-Blue and MR grisms have been used to cover different redshift ranges. Galaxies at 1.8 < z < 3.5 have been observed in the GOODS VIMOS-LR-Blue campaign. Galaxies at z < 1 and Lyman Break Galaxies at z > 3.5 have been observed in the VIMOS MR survey. Here we report results for the first 6 masks (out of 10 total) that have been analyzed from each of the LR-Blue and MR grisms. Spectra of 2344 spectra have been extracted from these 6 LR-Blue masks and 968 from 6 MR masks. 33% of the LR-Blue and 18% of the MR spectra are serendipitous observations. We obtained 1481 redshifts in the LR-Blue campaign and 656 in the MR campaign for a total success rate of 63% and 68%, respectively, which increase to 70% and 75% when only the primary targets are considered. By complementing our VIMOS spectroscopic catalog with all existing spectroscopic redshifts publicly available in the CDF-S, we created a redshift master catalog. By comparing this redshift compilation with different photometric redshift catalogs we estimate the completeness level of the CDF-S spectroscopic coverage in several redshift bins. The completeness level is very high, > 60%, at z < 3.5, and it is very uncertain at higher redshift. The master catalog has been used also to estimate completeness and contamination levels of different galaxy photometric selection techniques, such as the BzK, the so called 'sub'-U-dropout and the drop-out methods and to identify large scale structures in the field.

Lithospheric structure in the northern Appalachian Mountains: a detailed examination of the abrupt change in crustal thickness in northwestern Massachusetts
Creators: name: Masís Arce, Roberto José
Publisher: name: No Publisher Supplied
Year: 2023

description: The Appalachian Mountains were formed partially from multiple accretion of terranes along the Laurentia margin; these terranes were originally part of Gondwana. The present-day crustal structure holds a record of the tectonic history of the formation of the Appalachian Mountains. Previous geophysical studies identified an ~15 km vertical “Moho step” of the base of the crust in New England, USA along ~50 km horizontal distance and associated it with the surface boundary between Laurentia and the accreted terranes. Previous geochronological and thermochronological observations argue that the 60-km-thick crust in New England thickened during the assembly of the Appalachians and thinned during rifting and continental breakup. Using data from 2018 to 2021 from the dense New England Seismic Transects (NEST) experiment, which placed seismic stations spaced ~10 km apart within the area of the Moho step, I used receiver function (RF) analysis to detect P to SV converted waves in records of P and PKP phases. Single composite RFs constructed for each station identify the changes of impedance with depth. Multiple changes occur at all stations at different depths; in the west, beneath the eastern Laurentian margin, the pulse representing the crust-mantle boundary arrives almost 5.5 seconds after the initial P wave, whereas in the east, a similar pulse is at 3.5 seconds, corresponding to a depth of ~48 km and ~31 km, respectively. Based on these observations, I identified a juxtaposition of two boundaries instead of an abrupt step within crustal thickness. Complex geophysical signals registered at stations in the middle of the array (HALW, SHLB, L61B) indicate variation of impedance contrast. Based on results from previous studies and my own results, I created two models which represent the possible sequence of events that built the current lithospheric geometry after the accretion of Moretown terrane against the eastern edge of the Laurentia margin and the impact of following processes. The first model involves lithospheres of similar thickness for the eastern Laurentian margin and Moretown terrane at the moment of the first accretion event and later uplift of Moretown due to the second accretion event (Gander and Avalon terranes). Consecutively, the upper crust of Moretown was eroded, creating the current thickness differences between these two features.The second model proposed involves a heterogenous collision between Moretown and the Laurentia margin, creating the boundaries identified with geophysical data. This model shares the uplift process and erosion of Moretown terrane but it also includes a delamination process of the bottom part of the accreted terranes.

description: To compute robust 2D assembly plans, we present an approach that combines geometric planning with a deep neural network. We train the network using the Box2D physics simulator with added stochastic noise to yield robustness scores--the success probabilities of planned assembly motions. As running a simulation for every assembly motion is impractical, we train a convolutional neural network to map assembly operations, given as an image pair of the subassemblies before and after they are mated, to a robustness score. The neural network prediction is used within a planner to quickly prune out motions that are not robust. We demonstrate this approach on two-handed planar assemblies, where the motions are one-step translations. Results suggest that the neural network can learn robustness to plan robust sequences an order of magnitude faster than physics simulation.

description: We describe the recently developed on-shell bootstrap for computing one-loop amplitudes in non-supersymmetric theories such as QCD. The method combines the unitarity method with loop-level on-shell recursion. The unitarity method is used to compute cut-containing parts of amplitudes, and on-shell recursion is used for the remaining rational terms.

Prepayment and the valuation of Canadian mortgage-backed securities : a proportional hazards approach
Creators: name: Quick, Roger D.
Publisher: name: University of British Columbia
Year: 2009

description: This paper estimates both parametric and non-parametric proportional hazards models for a subset of Canadian mortgage-backed security data. The estimated parametric hazard function is then used to drive exogenous prepayments within an arbitrage-free model of the term structure of interest rates. Theoretical prices as well as option-adjusted spreads (OAS) are obtained for three different mortgage-backed securities using a Monte-Carlo simulation. Though no formal test is done to compare the ability of the different hazard models to explain observed market prices, the non-parametric baseline hazard is more consistent with the age-dependent prepayment provisions typical of most mortgage contracts in Canada.

description: This report examines the potential for statistical forecast models to improve the performance of the U.S. Department of Agriculture’s (USDA) long-term agricultural baseline projections for harvested area for U.S. corn, soybeans, and wheat. After-the-fact analysis for years 1997 to 2017 reveals the baseline projections have, historically, consistently overestimated the harvested area of wheat and underestimated soybean area. The baseline projections also tend to underestimate the corn area, though to a lesser degree. Part of the difference between the projections and realized values is likely attributable to policy, program, weather, and other unforeseen changes when USDA developed the projections. Still, the results of quantitative forecast models show there may be substantial potential for improvement on the existing methodology. Forecasts generated using 3 econometric time-series models did not improve performance relative to the current baseline approach for nearer forecast horizons but improved performance for projection horizon lengths of 8-10, 2-10, and 4-10 years for harvested area of corn, soybeans, and wheat, respectively, when using 1 of our statistical measures. The forecasts generated using the econometric models produce predictions with an average absolute forecasting error 10 years out that is between 26 percent to 60 percent smaller than those provided by baseline projections. The results suggest that econometric models offer the potential to improve the performance of forecasting long-term trends in agricultural markets. As of 2020, USDA begun using statistical forecast models such as these when developing its long-term agricultural projections as complements to the existing process. USDA is also in the process of testing these models for additional commodities to improve the long-term projections for all commodities.
