Subjects: International Relations/Trade

description: NAFTA is improving the field of agriculture in Canada, the United States, and Mexico. It is not doing so by enacting measures intended to improve the agricultural sector directly. Rather, the improvement is the indirect result of agriculture's dependence on transportation, telecommunications, intellectual property rights, and investment capital - all of which have been substantially improved by NAFTA. Improvement of these four areas has improved agriculture and will continue to improve it in the future.

description: We present 21-cm line observations of the spiral galaxy NGC 4559, made with the Westerbork Synthesis Radio Telescope. We have used them to study the HI distribution and kinematics, the relative amount and distribution of luminous and dark matter in this galaxy and, in particular, the presence of extra-planar gas. Our data do reveal the presence of such a component, in the form of a thick disk, with a mass of 5.9 x 10^8 Mo (one tenth of the total HI mass) and a mean rotation velocity 25-50 km/s lower than that of the thin disk. The extra-planar gas may be the result of galactic fountains but accretion from the IGM cannot be ruled out. With this study we confirm that lagging, thick HI layers are likely to be common in spiral galaxies.

description: The ``paperclip model'' is 2D model of Quantum Field Theory with boundary interaction defined through a special constraint imposed on the boundary values of massless bosonic fields (hep-th/0312168). Here we argue that this model admits equivalent ``dual'' description, where the boundary constraint is replaced by special interaction of the boundary values of the bosonic fields with an additional boundary degree of freedom. The dual form involves the topological theta-angle in explicit way.

description: The quantum problem of four particles in $\mathbb{R}^d$ ($d\geq 3$), with arbitrary masses $m_1,m_2,m_3$ and $m_4$, interacting through an harmonic oscillator potential is considered. This model allows exact solvability and a critical analysis of the Born-Oppenheimer approximation. The study is restricted to the ground state level. We pay special attention to the case of two equally heavy masses $m_1=m_2=M$ and two light particles $m_3=m_4=m$. It is shown that the sum of the first two terms of the Puiseux series, in powers of the dimensionless parameter $σ=\frac{m}{M}$, of the exact phase $Φ$ of the wave function $ψ_0=e^{-Φ}$ and the corresponding ground state energy $E_0$, coincide exactly with the values obtained in the Born-Oppenheimer approximation. A physically relevant rough model of the $H_2$ molecule and of the chemical compound $H_2O_2$ (Hydrogen peroxide) is described in detail. The generalization to an arbitrary number of particles $n$, with $d$ degrees of freedom ($d\geq n-1$), interacting through an harmonic oscillator potential is briefly discussed as well.

description: We estimate the weight gain for range calves as a polynomial function of calf age accounting for weather, sex, lagged calf weights relative to the growth function, and compensatory gains. Birth weights plus single day weighings that occurred around 3, 8, 12, and 20 months of age are the data used to estimate our growth function. This function is then used to determine the economic trade-off between herd size and calf sale weights, for both spring and fall sale dates. In addition, we evaluate the profitability of feeding supplement by increasing the rate of gain associated with our growth function when forage and nutrients are limiting for the two grazing environments of Southeast and Central Arizona. Using prices from 1980 to 1998, results indicate that the most profitable herd mix, sale date, and feeding protocol is 450 lb. calf sales with no supplemental feeding and sales occurring in May for both regions. Although, feeding supplement was not associated with the most profitable outcome, supplement increased the average return by $45 to $70 per AUY for sale weights of 550, 650, and 750 lbs.

description: Hermann Bondi's 1952 paper "On spherically symmetrical accretion" is recognized as one of the foundations of accretion theory. Although Bondi later remarked that it was "not much more than an examination exercise", his mathematical analysis of spherical accretion on to a point mass has found broad use across fields of astrophysics that were embryonic or non-existent at the time of the paper's publication. In this non-technical review, I describe the motivations for Bondi's work, and briefly discuss some of the applications of Bondi accretion in high energy astrophysics, galaxy formation, and star formation.

description: The proliferation of vast quantities of available datasets that are large and complex in nature has challenged universities to keep up with the demand for graduates trained in both the statistical and the computational set of skills required to effectively plan, acquire, manage, analyze, and communicate the findings of such data. To keep up with this demand, attracting students early on to data science as well as providing them a solid foray into the field becomes increasingly important. We present a case study of an introductory undergraduate course in data science that is designed to address these needs. Offered at Duke University, this course has no pre-requisites and serves a wide audience of aspiring statistics and data science majors as well as humanities, social sciences, and natural sciences students. We discuss the unique set of challenges posed by offering such a course and in light of these challenges, we present a detailed discussion into the pedagogical design elements, content, structure, computational infrastructure, and the assessment methodology of the course. We also offer a repository containing all teaching materials that are open-source, along with supplemental materials and the R code for reproducing the figures found in the paper.

description: We consider the half-wave maps (HWM) equation which provides a continuum description of the classical Haldane-Shastry spin chain on the real line. We present exact multi-soliton solutions of this equation. Our solutions describe solitary spin excitations that can move with different velocities and interact in a non-trivial way. We make an ansatz for the solution allowing for an arbitrary number of solitons, each described by a pole in the complex plane and a complex spin variable, and we show that the HWM equation is satisfied if these poles and spins evolve according to the dynamics of an exactly solvable spin Calogero-Moser (CM) system with certain constraints on initial conditions. We also find first order equations providing a Bäcklund transformation of this spin CM system, generalize our results to the periodic HWM equation, and provide plots that visualize our soliton solutions.

Systematic and quantitative approach for the identification of high energy gamma-ray source populations

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: A large fraction of the detections to be made by the Gamma-ray Large Area Space Telescope (GLAST) will initially be unidentified. We argue that traditional methodological approaches to identify individuals and/or populations of $γ$-ray sources will encounter procedural limitations. These limitations will hamper our ability to classify source populations lying in the anticipated dataset with the required degree of confidence, particularly those for which no member has yet been convincingly detected in the predecessor experiment EGRET. Here we suggest a new paradigm for achieving the classification of $γ$-ray source populations based on the implementation of an a priori protocol to search for theoretically-motivated candidate sources. In order to protect the discovery potential of the sample, it is essential that such paradigm will be defined before the data is unblinded. Key to the new procedure is a statistical assessment by which the discovery of a new population can be claimed. Although we explicitly refer here to the case of GLAST, the scheme we present may be adapted to other experiments confronted with a similar problematic.

description: Annualized cow ownership costs represent a large component of the total costs in a cow-calf enterprise, and therefore impact profitability. Annualized cow costs are determined in large part by the price or cost of that cow when it entered the herd. We find that ownership costs, and in turn cow-herd profitability, can be significantly impacted by heifer replacement strategies. Timing (within the cattle cycle) and method (raise vs. purchase) are both important considerations.

description: We present a sample of 218 new quasar pairs with proper transverse separations R_prop < 1 Mpc/h over the redshift range 0.5 < z < 3.0, discovered from an extensive follow up campaign to find companions around the Sloan Digital Sky Survey and 2dF Quasar Redshift Survey quasars. This sample includes 26 new binary quasars with separations R_prop < 50 kpc/h (theta < 10 arcseconds), more than doubling the number of such systems known. We define a statistical sample of binaries selected with homogeneous criteria and compute its selection function, taking into account sources of incompleteness. The first measurement of the quasar correlation function on scales 10 kpc/h < R_prop < 400 kpc/h is presented. For R_prop < 40 kpc/h, we detect an order of magnitude excess clustering over the expectation from the large scale R_prop > 3 Mpc/h quasar correlation function, extrapolated down as a power law to the separations probed by our binaries. The excess grows to ~ 30 at R_prop ~ 10 kpc/h, and provides compelling evidence that the quasar autocorrelation function gets progressively steeper on sub-Mpc scales. This small scale excess can likely be attributed to dissipative interaction events which trigger quasar activity in rich environments. Recent small scale measurements of galaxy clustering and quasar-galaxy clustering are reviewed and discussed in relation to our measurement of small scale quasar clustering.

Women’s experiences of seeking and receiving help for postpartum depression
Creators: name: Munro, Pamela Joan
Publisher: name: University of British Columbia
Year: 2009

description: Postpartum depression (PPD) is a serious health issue that affectsl3% of women worldwide and has serious consequences for women and their families. Despite regular contact with healthcare services in the postpartum period, PPD remains largely unrecognized by women themselves, and undetected and untreated by healthcare providers. This study comprises the qualitative component of a collaborative four-part research project that explored the phenomenon of PPD. Grounded theory, a method aimed at generating a substantive theory about social phenomenon, was used to guide the research process. Thirty women who identified themselves as having experienced PPD participated in one of six focus group discussions conducted in the Fraser Valley Health Region of British Columbia. Constant comparative analysis of the qualitative data revealed a complex and evolving process of help seeking for PPD consisting of three phases. Women's choices of when to seek help, whom to seek help from, and what kind of help to seek differed among phases. The first phase, waiting to be rescued, was described by the women as falling apart, trying to survive, having nowhere to turn, and reaching the end of the line. Reaching the end of the line was a significant turning point in the help seeking process. The second phase, giving in and opening up, was characterized as putting self at risk, knocking on doors, trying out options, being influenced by beliefs about help seeking, and feeling better. Feeling better was experienced as an uneasy peace in which women continued to feel vulnerable to relapse. The third phase, tuning-in to self, was identified as looking back, moving forward, and finally a new sense of self, forever changed but ultimately wiser and stronger. Breaking the silence emerged as the core category in this substantive theory that describes women's difficult journey from silence to voice. The theory generated from this study increases knowledge about this important and difficult human experience and guides nurses in the assessment, planning, implementation, and evaluation of nursing care for women who experience PPD.

description: The most studied perovskite-based solar cells reported up to date contain the toxic lead in its composition. Photovoltaic research and development towards non-toxic, lead-free perovskite solar cells are critical to finding alternatives to reduce human health concerns associated with them. Bismuth-based perovskite variants, especially in the form of methylammonium bismuth iodide (MBI), is a good candidate for the non-toxic light absorber. However, the reported perovskite variant MBI thin flms prepared by the solution process so far suffers from poor morphology and surface coverage. In this work, we investigate for the first time the optoelectronic, crystallographic and morphological properties of MBI thin flms prepared via thermal co-evaporation of MAI and BiI3. We find by modifying the precursor ratio that the layer with pure MBI composition lead to uniform, compact and homogeneous layers, broadening the options of deposition techniques for lead-free based perovskite solar cells.
Implementation of stellar heating feedback in simulations of star cluster formation: effects on the initial mass function

description: Explaining the initial mass function (IMF) of stars is a long-standing problem in astrophysics. The number of complex mechanisms involved in the process of star cluster formation, such as turbulence, magnetic fields and stellar feedback, make understanding and modeling the IMF a challenging task. In this paper, we aim to assert the importance of stellar heating feedback in the star cluster formation process and its effect on the shape of the IMF. We use an analytical sub-grid model to implement the radiative feedback in fully three-dimensional magnetohydrodynamical (MHD) simulations of star cluster formation, with the ultimate objective of obtaining numerical convergence on the IMF. We compare a set of MHD adaptive-mesh-refinement (AMR) simulations with three different implementations of the heating of the gas: 1) a polytropic equation of state (EOS), 2) a spherically symmetric stellar heating feedback, and 3) our newly developed polar heating model that takes into account the geometry of the accretion disc and the resulting shielding of stellar radiation by dust. For each of the three heating models, we analyse the distribution of stellar masses formed in ten molecular cloud simulations with different realizations of the turbulence to obtain a statistically representative IMF. We conclude that stellar heating feedback has a profound influence on the number of stars formed and plays a crucial role in controlling the IMF. We find that the simulations with the polar heating model achieve the best convergence on the observed IMF.

Nonlinear stability of rarefaction waves for a viscous radiative and reactive gas with large initial perturbation

description: We investigate the time-asymptotically nonlinear stability of rarefaction waves to the Cauchy problem of an one-dimensional compressible Navier-Stokes type system for a viscous, compressible, radiative and reactive gas, where the constitutive relations for the pressure $p$, the specific internal energy $e$, the specific volume $v$, the absolute temperature $θ$, and the specific entropy $s$ are given by $p=Rθ/v +aθ^4/3$, $e=C_vθ+avθ^4$, and $s=C_v\ln θ+ 4avθ^3/3+R\ln v$ with $R>0$, $C_{v}>0$, and $a>0$ being the perfect gas constant, the specific heat and the radiation constant, respectively. For such a specific gas motion, a somewhat surprising fact is that, general speaking, the pressure $\widetilde{p}(v,s)$ is not a convex function of the specific volume $v$ and the specific entropy $s$. Even so, we show in this paper that the rarefaction waves are time-asymptotically stable for large initial perturbation provided that the radiation constant $a$ and the strength of the rarefaction waves are sufficiently small. The key point in our analysis is to deduce the positive lower and upper bounds on the specific volume and the absolute temperature, which are uniform with respect to the space and the time variables, but are independent of the radiation constant $a$.

description: Chitosan and chitin are categorized as low cost, renewable and eco-friendly biopolymers. However, they have low mechanical properties and unfavorable pore properties in terms of low surface area and total pore volume that limit their adsorption application. Many studies have shown that such weaknesses can be avoided by preparation of composites with carbonaceous materials from these biopolymers. This article provides a systematic review on the preparation of chitosan/chitin-carbonaceous material composites. Commonly used carbonaceous materials such as activated carbon, biochar, carbon nanotubes, graphene oxide and graphene to prepare composites are discussed. The application of chitosan/chitin-carbonaceous material composites for the adsorption of various water pollutants, and the regeneration and reusability of adsorbents are also included. Finally, the challenges and future prospects for the adsorbents applied for the adsorption of water pollutants are summarized.

description: We here report the detection of extended HeII4686 nebular emission in the central region of NGC1569 using the integral field spectrograph MEGARA at the 10.4-m Gran Telescopio Canarias. The observations cover a Field of View (FoV) of 12.5 arcsec x 11.3 arcsec at seeing-limited spatial resolution of ~15 pc and at a spectral resolution of R=6000 in the wavelength range 4330--5200 Angstrom. The emission extends over a semi-circular arc of ~40 pc width and ~150 pc diameter around the super star cluster A (SSC-A). The Av derived using Balmer decrement varies from the Galactic value of 1.6 mag to a maximum of ~4.5 mag, with a mean value of 2.65+/-0.60 mag. We infer 124+/-11 Wolf-Rayet (WR) stars in SSC-A using the HeII4686 broad feature and Av=2.3 mag. The He+ ionizing photon rate from these WR stars is sufficient to explain the luminosity of the HeII4686 nebula. The observationally-determined total He+ and H0 ionizing photon rates, their ratio, and the observed number of WR stars in SSC-A are all consistent with the predictions of simple stellar population models at an age of 4.0+/-0.5 Myr, and mass of (5.5+/-0.5)x10^5 Msun. Our observations reinforce the absence of WR stars in SSC-B, the second most massive cluster in the FoV. None of the other locations in our FoV where HeII4686 emission has been reported from narrow-band imaging observations contain WR stars.

description: We estimate a simultaneous bivariate qualitative choice model of Arizona agribusiness firms propensity to trade and visit as a tourist with the cross-border state of Sonora, Mexico. The trade equation is estimated as an ordered probit model with responses of: 1) a firm has not ever traded or investigated doing any trading activities with Sonora, 2) the firm has not done any trade with Sonora but they have investigated doing business in this cross-border state, and 3) the firm has traded with Sonora, either directly or through a second handler like a broker. A proprietors propensity to visit Sonora as a tourist is modeled from the binary response of whether the individual has ever visited Sonora as a tourist or not. Simultaneity arises since both trade and tourist visits are hypothesized to influence one another. Results indicate that tourist visits have a greater influence on whether firms trade than traditional variables considered like firm age and size. Venture business visits, quantified through the tourism equation, were also found to have a greater impact on an agribusiness firm's propensity to trade than traditional variables. Our results suggest that communities seeking to develop and expand cross-border trading activities should target entrepreneurs with an exploratory and venture spirit first. Then, target firms that are fairly established (over 15 years in age) and desire to diversity their production risk through multiple geographic production regions. Firm size and foreign language fluency of the agribusiness owner were found to be less significant than tourist visits, venture business visits, and firm age.

description: We study the diffusion of heavy quarks in the Quark Gluon Plasma using the Langevin equations of motion and estimate the contribution of the transport peak to the Euclidean current-current correlator. We show that the Euclidean correlator is remarkably insensitive to the heavy quark diffusion coefficient and give a simple physical interpretation of this result using the free streaming Boltzmann equation. However if the diffusion coefficient is smaller than $\sim 1/(πT)$, as favored by RHIC phenomenology, the transport contribution should be visible in the Euclidean correlator. We outline a procedure to isolate this contribution.

description: A body of evidence suggests that myocardial infarctions (MI) that are associated with percutaneous coronary intervention (PCI) have prognostic significance but it is uncertain whether remote ischaemic preconditioning (RIPC) offers periprocedural cardioprotection at the time of PCI. Medline, Embase, the Cochrane Central Register of Controlled Trials and conference records were searched (January 1986 to August 2013) for randomised trials that evaluated the effect of RIPC induced by limb ischaemia–reperfusion versus no RIPC in patients who were undergoing PCI. All outcomes were considered for inclusion in the systematic review. Relevant data were extracted and summarised. Pooled odds ratios determined the effect of RIPC compared to control on three prespecified outcomes: troponin positive events in elective PCI, periprocedural MI incidence in elective PCI and acute kidney injury (AKI) incidence in emergency or elective PCI. Eight trials (1119 patients) were found of which six (983 patients) had primary outcomes that were significantly in favour of RIPC. There was no difference in troponin positive events between RIPC and control groups (pooled OR 0.529, 95%CI 0.206–1.358, p = 0.185) (three studies, 377 patients). There was a significant reduction in periprocedural MI incidence with RIPC (pooled OR = 0.577, 95%CI 0.400–0.833, p = 0.003) (four studies, 636 patients). There was no difference in AKI incidence (pooled OR = 0.672, 95%CI 0.252–1.787, p = 0.425) (two studies, 407 patients). Primary outcomes favoured RIPC in most of the studies. RIPC significantly reduced the incidence of periprocedural MI. Included studies were heterogeneous in methodology and quality

description: This paper provides an examination of the EKC Hypothesis applied to deforestation in the Brazilian Pantanal wetland. It is hypothesized that the unsustainable subdivision of many of the larger ranches due to inheritance may result in greater deforestation pressure than a less equal distribution of land and animal resources. The analysis advances understanding in this area on several dimensions: an intra-regional rather than international approach is examined; deforestation is addressed; and land and cattle wealth serve as proxies for income and wealth among agriculturists, where income measures are notoriously poor indicators of welfare.

description: The sensitivity of the gravitational-wave detector KAGRA, presently under construction, will be limited by quantum noise in a large fraction of its spectrum. The most promising technique to increase the detector sensitivity is the injection of squeezed states of light, where the squeezing angle is dynamically rotated by a Fabry-Pérot filter cavity. One of the main issues in the filter cavity design and realization is the optical losses due to the mirror surface imperfections. In this work we present a study of the specifications for the mirrors to be used in a 300 m filter cavity for the KAGRA detector. A prototype of the cavity will be constructed at the National Astronomical Observatory of Japan, inside the infrastructure of the former TAMA interferometer. We also discuss the potential improvement of the KAGRA sensitivity, based on a model of various realistic sources of losses and their influence on the squeezing amplitude.

description: Epichlorohydrin crosslinked chitosan/carbon–clay (CSCC) biohybrid adsorbent was prepared for the adsorption of cationic methylene blue (MB) and anionic azo acid blue 29 (AB 29). The 40:60 wt% of chitosan (CS) and carbon–clay (CC) was selected as the best biohybrid adsorbent (CS40CC60) for the adsorption of both dyes. The adsorption of MB and AB 29 on CS40CC60 was carried out in a batch process to investigate the effects of initial dye concentration (25–400 mg/L), initial pH (3−11), contact time and adsorption temperature (30, 40 and 50 °C). The kinetics results of dyes adsorption onto CS40CC60 fit well to the pseudo-second-order model. The isotherms analysis demonstrated that the Freundlich isotherm described the adsorption data, and the qmax (mg/g) were 95.31 for MB and 167.35 for AB29 at 50 °C. These findings reveal the potential and effectiveness of the newly prepared biohybrid adsorbent for the adsorption of both dyes.

description: The spectrum of meson and diquark excitations of dense color neutral cold quark matter is investigated in the framework of a 2-flavored Nambu--Jona-Lasinio type model, including a quark $μ$- and color $μ_8$ chemical potential. It was found out that in the color superconducting (2SC) phase, i.e. at $μ>μ_c=342$ MeV, $μ_8$ aquires rather small values $\sim$ 10 MeV in order to ensure the color neutrality. In this phase the $π$- and $σ$ meson masses are evaluated around $\sim$ 330 MeV. The spectrum of scalar diquarks in the color neutral 2SC phase consists of a heavy ($\rm SU_c(2)$-singlet) resonance with mass $\sim$ 1100 MeV, four light diquarks with mass $3|μ_8|$, and one Nambu --Goldstone boson which is in accordance with the Goldstone theorem. Moreover, in the 2SC phase there are five light stable particles as well as a heavy resonance in the spectrum of pseudo-scalar diquarks. In the color symmetric phase, i.e. for $μ

description: The United States imposed a tariff-rate quota (TRQ) on lamb meat in July 1999. Early analysis suggested the possibility that lamb growers could lose welfare via the creation of packer market power. This paper considers how subsequent events modify that analysis. Observed prices suggest reduced pass-through. Lamb prices are unchanged and more stable. Using an annual quota instead of a quarterly quota reduces the opportunity for market conduct switching. Early termination of the TRQ to comply with the WTO rulings magnifies any welfare loss. Assistance payments prevent welfare losses to growers with little impact on the market.

description: Autocorrelation of two pions produced in heavy-ion collisions at intermediate $p_T$ is calculated in the framework of the recombination model. The differences of the pseudo-rapidities and azimuthal angles of the two pions are related to the angle between two shower partons in a jet. It is shown how the autocorrelation distribution reveals the properties of jet cone of the shower partons created by high-$p_T$ partons in hard collisions.

description: This paper examines the changes in the farm sector wealth from 1950 through 1999. The study uses Theil's entropy-based measure of inequality of farm equity by ten regions of the U.S. The entropy-measure is then used to decompose U.S. inequality into within-region and between-region differences. Results show that for the period 1950 to 1993, relative to the number of farms per state, farm wealth in the U.S. became more equally distributed. Further, results show that inequality in wealth may be on the rise in recent years. Key words: inequality, Theil's entropy, farm equity, regional decomposition.

description: The D0 experiment at Fermilab's Tevatron will record several petabytes of data over the next five years in pursuing the goals of understanding nature and searching for the origin of mass. Computing resources required to analyze these data far exceed capabilities of any one institution. Moreover, the widely scattered geographical distribution of D0 collaborators poses further serious difficulties for optimal use of human and computing resources. These difficulties will exacerbate in future high energy physics experiments, like the LHC. The computing grid has long been recognized as a solution to these problems. This technology is being made a more immediate reality to end users in D0 by developing a grid in the D0 Southern Analysis Region (D0SAR), D0SAR-Grid, using all available resources within it and a home-grown local task manager, McFarm. We will present the architecture in which the D0SAR-Grid is implemented, the use of technology and the functionality of the grid, and the experience from operating the grid in simulation, reprocessing and data analyses for a currently running HEP experiment.

Explaining the unobserved: why quantum mechanics is not only about information

description: A remarkable theorem by Clifton, Bub and Halvorson (2003)(CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be regarded as a ``principle'' theory about (quantum) information rather than a ``constructive'' theory about the dynamics of quantum systems. Here we criticize Bub's principle approach arguing that if the mathematical formalism of quantum mechanics remains intact then there is no escape route from solving the measurement problem by constructive theories. We further propose a (Wigner--type) thought experiment that we argue demonstrates that quantum mechanics on the information--theoretic approach is incomplete.

Machine learning depinning of dislocation pileups

description: We study a one-dimensional model of a dislocation pileup driven by an external stress and interacting with random quenched disorder, focusing on predictability of the plastic deformation process. Upon quasistatically ramping up the externally applied stress from zero the system responds by exhibiting an irregular stress--strain curve consisting of a sequence of strain bursts, i.e., critical-like dislocation avalanches. The strain bursts are power-law distributed up to a cutoff scale which increases with the stress level up to a critical flow stress value. There, the system undergoes a depinning phase transition and the dislocations start moving indefinitely, i.e., the strain burst size diverges. Using sample-specific information about the pinning landscape as well as the initial dislocation configuration as input, we employ predictive models such as linear regression, simple neural networks and convolutional neural networks to study the predictability of the simulated stress--strain curves of individual samples. Our results show that the response of the system -- including the flow stress value -- can be predicted quite well, with the correlation coefficient between predicted and actual stress exhibiting a non-monotonic dependence on strain. We also discuss our attempts to predict the individual strain bursts.
