description: The food and fiber system is one of the largest sectors in the U.S. economy, even though farming itself takes up only about 3 percent of the total work force. Within the last 30 years, the food and fiber system has found itself increasingly reliant on nonfarm industries and increasingly affected by general economic developments, not only within the Nation but from overseas as well. As the farm work force has shrunk, nonmetro areas' dependence on farming has declined too. Today only about a third of the nonmetro counties rely on farming for more than 20 percent of total personal income.

FAIR data

description: Presented at Goldschmidt 2021, Session 14fO2 Abstract As open access publishing and FAIR data principles (findable, accessible, interoperable, reusable) become the new standard, geochemical data archives must not get left behind. Free access to up-to-date, scientifically curated data archives that are efficiently connected to the international community are essential. GEOROC is a leading source of geochemical and isotopic datasets, is connected to the „Interdisciplinary Earth Data Alliance“, and has facilitated thousands of peer-reviewed publications and new avenues of geochemical research. In the new Digital Geochemical Data Infrastructure (DIGIS) concept of GEOROC 2.0, our goal is to continue and enhance the existing data collection by generating a connected platform that meets future challenges of digital data-based research and provides advanced service to the community. Our approach is to (1) realign GEOROC with current and future demands in digital geochemical research, especially regarding FAIR principles; and (2) identify, develop and recommend good-practice rules for the curation of physical samples linked to the GEOROC 2.0 platform. This includes an interoperable metadata model as well as metadata and data exchange via standardised application interfaces (APIs). “Digital geochemistry” not only involves archiving and structuring of geochemical data but also the development of new tools and methods of data analysis. Increasing the accessibility and ease-of-use of open geochemical databases ensures applications in other research areas. For instance, global soil research depends on representative and global coverage of rock substrate analyses. Spectral remote sensing of planetary surfaces requires mineral and rock reference compositions on a planetary scale. Archaeological studies linking artefacts to their provenance are based on knowing the chemical and isotopic composition of potential sources. The DIGIS concept for GEOROC 2.0 includes open access to end-to-end text and data mining, integration of data DOIs, links to a geochemical sample storage system via the International GeoSample Number (IGSN), multi-way data harvesting capabilities as well as state-of-the-art connectivity to other databases. The scientific development of GEOROC 2.0 as well as the re-organisation of its IT infrastructure will allow the database to expand into a more diverse range of geochemical data and thus ensure continued open access to a FAIR database for future Earth science research.

description: We trace a systematic and consistent method to precisely numerate the magnitude range for various structural and isospin compositional properties of the neutron star. Incompressibility, symmetry energy, slope parameter and curvature of a neutron star are investigated using the relativistic energy density functional within the framework of coherent density fluctuation model. The analytical expression for the energy density functional of the neutron star matter is motivated from the Br$\ddot{u}$ckner functional and acquired by the polynomial fitting of the saturation curves for three different relativistic mean-field parameter sets (NL3, G3 and IU-FSU). The modified functional is folded with the neutron star's density-dependent weight function to calculate the numerical values for incompressibility and symmetry energy using the coherent density fluctuation model. NL3 parameter set, being the stiffest equation of state, endue us with a higher magnitude of all the properties compared to the other two parameter sets.

description: Following recent developments in the classification of bosonic short-range entangled phases, we examine many-body quantum systems whose ground state fractionalization obeys the Lieb-Schultz-Mattis (LSM) theorem. We generalize the topological classification of such phases by LSM anomalies (arXiv:1907.08204) to take magnetic and non-symmorphic lattice effects into account, and provide direct computations of the LSM anomaly in specific examples. We show that the anomaly-free condition coincides with established filling constraints (arXiv:1705.09298, arXiv:1505.04193), and we also derived new ones on novel crystalline quantum systems.

description: We investigate the dielectrophoretic motion of charge-neutral, polarizable nanocolloids through molecular dynamics simulations. Comparison to analytical results derived for continuum systems shows that the discrete charge distributions on the nanocolloids have a significant impact on their coupling to the external field. Aggregation of nanocolloids leads to enhanced dielectrophoretic transport, provided that increase in the dipole moment upon aggregation can overcome the related increase in friction. The dimer orientation and the exact structure of the nanocolloid charge distribution are shown to be important in the enhanced transport.

We find that gluons contribute (37 +/- 8 +/- 12)% of the pion's light cone momentum. The bare matrix elements corresponding to the trace anomaly contribution to the pion mass are also obtained. The discretizations of the energy-momentum tensor we use have other promising applications, ranging from calculating the origin of hadron spin to QCD thermodynamics.

Genuine activation of nonlocality: From locally available to locally hidden information

Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Quantum nonlocality has different manifestations that, in general, are revealed by local measurements of the parts of a composite system. In this paper, we study nonlocality arising from a set of orthogonal states that cannot be perfectly distinguished by local operations and classical communication (LOCC). Such a set is deemed nonlocal, for a joint measurement on the whole system is necessary for perfect discrimination of the states with certainty. On the other hand, a set of orthogonal states that can be perfectly distinguished by LOCC is believed to be devoid of nonlocal properties. Here, we show that there exist orthogonal sets that are locally distinguishable but without local redundancy (i.e., they become nonorthogonal on discarding one or more subsystems) whose nonlocality can be activated by local measurements. In particular, a state chosen from such a set can be locally converted, with certainty, into another state, the identity of which can now only be ascertained by global measurement and no longer by LOCC. In other words, a locally distinguishable set without local redundancy may be locally converted into a locally indistinguishable set with certainty. We also suggest an application, namely, local hiding of information, that allows us to locally hide locally available information without losing any part. Once hidden, the information in its entirety can only be retrieved using entanglement.

description: Perturbations are ubiquitous in metabolism. A central tool to understand and control their influence on metabolic networks is sensitivity analysis, which investigates how the network responds to external perturbations. We follow here a structural approach: the analysis is based on the network stoichiometry only and it does not require any quantitative knowledge of the reaction rates. We consider perturbations of reaction rates and metabolite concentrations, at equilibrium, and we investigate the responses in the network. For general metabolic systems, this paper focuses on the sign of the responses, i.e. whether a response is positive, negative or whether its sign depends on the parameters of the system. In particular, we identify and describe the subnetworks that are the main players in the sign description. These subnetworks are associated to certain kernel vectors of the stoichiometric matrix and are thus independent from the chosen kinetics.

description: The Research Software Directory is a content management system aimed at promoting discoverability, re-use, and citation of research software. The system harvests information from sources such as GitHub, Zenodo and Zotero, and shows research software in the context of associated projects, publications, data sets, and other research output, thereby enabling users to quickly evaluate whether the software is suitable for their purposes. It highlights the team of contributors that has created the software and employs search engine optimization (SEO) techniques to increase the findability of the software it contains. By providing software citation information, it clarifies how the software should be cited if it is reused. In addition, it enables a qualitative assessment of software impact. The system is open-source and is built using common standards, allowing it to link to other services in the open science ecosystem. The Research Software Directory 1) increases the visibility of research software, 2) stimulates reuse of research software, 3) stimulates software citation, and 4) improves the recognition of the position of research software engineers. These factors will contribute to the future of scholarly communication by increasing the discoverability of research software, as well as promote the recognition of research software as a key scholarly output.

description: We provide a calculus for the presentation of closed 3-manifolds via nullhomotopic filling Dehn spheres and we use it to define an invariant of closed 3-manifolds by applying the state-sum machinery. As a potential application of this invariant, we show how to get lower bounds for the Matveev complexity of P2-irreducible closed 3-manifolds. We also describe an easy algorithm for constructing a nullhomotopic filling Dehn sphere of each closed 3-manifold from any of its one-vertex triangulations.

Product interactions and rivalry among multiproduct firms : an application of characteristics theory
Creators: name: Burton, Peter Steven
Publisher: name: University of British Columbia
Year: 2010

description: A model based upon the differences in the profitability of producing various combinations of goods is presented as a practical method of analysing product choice by multiproduct firms. Characteristics theory is used to construct the market opportunity frontiers that were formed by fifteen common insecticides during each year between 1944 and 1987. These frontiers, which utilize the three attributes that are used to compare the insecticides in the industry literature, illustrate the combinations of characteristics that the products yield for some budget. Construction of the frontiers provides the first opportunity to check the principal prediction of characteristics theory, that all products are priced to appear on the market opportunity frontiers. The prediction holds during fifteen years of the study. Deviations from the prediction during the other years are due to one product and can be accounted for by the measurement errors of the characteristics. The market opportunity frontiers are also utilized to calculate the implicit prices of characteristics on each facet of the frontier. These prices, and convexity of the frontier, are then used to determine bounds on the prices of eight additional products for which price data are unavailable. A proposition is presented which indicates that a product yields greater profits to a firm producing a product which neighbours it on the market opportunity frontier. Increased profits due to these relationships between certain combinations of products, such as whether they are neighbouring or chemically similar, are also shown to increase the probability that a firm will produce these combinations. Logit estimations are conducted to determine how the relationships between two goods influence the probabilities of a firm introducing or producing both. The empirical results are able to predict (with a 50 to 60% success rate) the identity of the firms which introduced or produced particular products based upon the other products in each firm's portfolio. The principal contributions of this thesis are that it provides the first empirical support for the predictions of characteristics theory and that it presents an approach which allows the empirical analysis of product choice by multiproduct firms.
Threaded clinical trial evidence to enhance science discoverability: How a simple link between registration and reporting can improve scholarly communication

description: Informed clinical guidance and health policy relies on clinicians, policymakers, and guideline developers finding comprehensive clinical evidence. Linking registrations and publications of the same clinical trial improves discoverability and is required by the World Health Organization (WHO), the International Committee of Medical Journal Editors (ICMJE), and the Consolidated Standards of Reporting Trials (CONSORT). This responsible transparency practice costs researchers minimal effort: seconds for pasting a trial registration number into the publication abstract and full-text, and minutes for adding the publication link and DOI to the registry entry. However, the rate of compliance with this requirement remains low: in a recent study of almost 2,000 registered and published German trials, we found 75% failed to reference trial registration numbers in both the abstract and full-text of their results publications, and 50% of trial registrations did not contain links to their results publications. In this lightning talk, we demonstrate a novel automated pipeline for evaluating the links between registrations and publications and present simple steps for improving clinical science discoverability. We propose actionable recommendations for researchers, publishers, librarians, bibliometricians, funders, computer scientists, and the greater FORCE11 community.

description: Topological winding and unwinding in a quasi-one-dimensional metastable Bose-Einstein condensate are shown to be manipulated by changing the strength of interaction or the frequency of rotation. Exact diagonalization analysis reveals that quasidegenerate states emerge spontaneously near the transition point, allowing a smooth crossover between topologically distinct states. On a mean-field level, the transition is accompanied by formation of grey solitons, or density notches, which serve as an experimental signature of this phenomenon.

description: An effective online recommendation system should jointly capture users' long-term and short-term preferences in both users' internal behaviors (from the target recommendation task) and external behaviors (from other tasks). However, it is extremely challenging to conduct fast adaptations to real-time new trends while making full use of all historical behaviors in large-scale systems, due to the real-world limitations in real-time training efficiency and external behavior acquisition. To address these practical challenges, we propose a novel Long Short-Term Temporal Meta-learning framework (LSTTM) for online recommendation. It arranges user multi-source behaviors in a global long-term graph and an internal short-term graph, and conducts different GAT-based aggregators and training strategies to learn user short-term and long-term preferences separately. To timely capture users' real-time interests, we propose a temporal meta-learning method based on MAML under an asynchronous optimization strategy for fast adaptation, which regards recommendations at different time periods as different tasks. In experiments, LSTTM achieves significant improvements on both offline and online evaluations. It has been deployed on a widely-used online recommendation system named WeChat Top Stories, affecting millions of users.

description: Open Access (OA) broadens the dissemination of research discoveries and allows others to build on existing knowledge. While there is evidence that Open Access is growing, many publications remain behind a paywall. In many cases, journal or publisher self-archiving policies allow researchers to make a version of their publication openly accessible in a repository, sometimes after an embargo period (green OA). In this study, we investigated the realised potential of green OA in a sample of 1929 publications from interventional clinical trials published in 2010 – 2020. Included trials were registered in ClinicalTrials.gov or DRKS, conducted at a German UMC, and reported as complete in 2009 – 2017. We queried Unpaywall (OurResearch) via its API to assess the OA status of publications in this sample. We then queried Shareyourpaper (OA.Works) via its API to obtain article-level self-archiving permissions for paywalled publications in this sample. We identified 881 paywalled publications, 86% (n=760) of which had a current "best permission" for self-archiving the accepted or published version in an institutional repository (query date: 03/12/2021). The analysis was limited to publications resolving in Unpaywall and focused on the “best permission” in Shareyourpaper for archiving in an institutional repository. These findings are informing part of an ongoing intervention with trialists at the Charité to increase clinical trial transparency. Our case study provides a concrete example of how available tools may be used to obtain actionable information related to self-archiving at scale, and thereby empower efforts to increase science discoverability.

description: We propose a novel mechanism for enhancing the primordial gravitational waves without significantly affecting the curvature perturbations produced during inflation. This is achieved due to non-linear sourcing of resonantly amplified scalar field fluctuations. Our result is an explicit scale-dependent counter-example of the famous Lyth bound, which opens up a promising perspective of producing detectable inflationary tensor modes with low-scale inflation and a sub-Planckian field excursion. We explicitly demonstrate the testability of our mechanism with upcoming Cosmic Microwave Background B-mode observations.

description: The dissemination of open publication metadata contributes significantly to the visibility of publications: If a publication is not listed in a service, it cannot be found. The quality and completeness of this data, in turn, help to ensure that articles can be correctly assessed by researchers. An important point here is citation metadata, which on the one hand can be used as a sorting or filtering criterion in scientific discovery services, and on the other hand indicate the interconnectedness of a publication in the graph of scientific publications. This in turn enables an exploratory search for related publications. We will highlight how journals (especially small and independent journals) using the Open Journal Systems (OJS) software can contribute to a commons of open citation information to improve the visibility and discoverability of (open access) publications.

description: A large and mostly unexplored part of the phase diagram lies above the critical point. The supercritical matter was traditionally believed to be physically homogeneous with no discernible differences between liquidlike and gaslike states. More recently, several proposals have been put forward challenging this view, and here we review the history of this research. Close to the critical point, persisting critical anomalies enable the separation of the supercritical state into two different states. About a decade ago, it was proposed that the Frenkel line (FL), corresponding to the dynamical transition of particle motion and related thermodynamic and structural transitions, gives a unique and path-independent way to separate the supercritical states into two qualitatively different states and extends to arbitrarily high pressure and temperature on the phase diagram. Here, we review several lines of enquiry that followed. We focus on the experimental evidence of transitions in deeply supercritical Ne, N$_2$, CH$_4$, C$_2$H$_6$, CO$_2$ and H$_2$O at the FL detected by a number of techniques including X-ray, neutron and Raman scattering experiments. %Except for H$_2$O, these experiments were stimulated by the FL and followed the state points of the FL mapped in preceding calculations. We subsequently summarise other developments in the field, including recent extensions of analysis of dynamics at the FL, quantum simulations, topological and geometrical approaches as well as universality of properties at the FL. Finally, we review current theoretical understanding of the supercritical state and list open problems in the field.

A possibility of identifying magnetic scatters even by non spin-polarized scanning tunneling spectroscopy is explained.

BigDataGrapes D8.5 - Evaluation Report and KPI Assessment
Creators: name: Kasimati, Aikaterini
Publisher: name: Zenodo
Year: 2020

description: The deliverable D8.5, “Evaluation Report and KPI Assessment”, aims to provide a report on the results of the application piloting sessions, in line with the defined experimental protocols and in accordance with the evaluation methodology. Based on the experimental and evaluation protocols defined in the context of T8.2, pilot partners monitor the execution of the application pilots and evaluate their results qualitatively and quantitatively against the Key Performance Indicators (KPIs) defined by the relevant protocols. The objective of this deliverable is to provide, in the first part, an overview and a first evaluation regarding each of the five pilots’ progress, stating and explaining the current status of development, the successfulness of implementation and the achieved performance of the BigDataGrapes Pilots. This is the updated and final version of this deliverable, including the evaluation of the pilots. Deliverable D8.5, “Evaluation Report and KPI Assessment”, is based on the individual Qualitative and Quantitative Evaluations of the following pilots: Table and Wine Grapes Pilot (AUA), Wine Making Pilot (INRAE), Farm Management Pilot (ABACO & Geocledian), Natural Cosmetics Pilot (Symbeeosis) and Food Protection Pilot (Agroknow). This document reports an overview of the application piloting sessions’ results, both qualitatively and quantitatively against the defined KPIs, for each of the five pilots. Information was directly provided by the pilot leaders to ensure the specificity of the guidelines and the smooth progress and evaluation of all piloting sessions. The document is structured as follows: Chapter 1 serves as an introduction to the deliverable whereas Chapter 2 provides an overview of the five pilots’ Qualitative and Quantitative evaluation. Each of the pilots’ Qualitative Evaluation Summary is divided in five sections: the pilot’s evaluation summary, plan progress, status of implementation, impact and potential pilot modification or required plans for improvement. For the Quantitative evaluation a KPIs list along with baseline values have been defined, including the Domain Specific KPIs only for those pilots that this applies and the Technological KPIs for all pilots. This part of the deliverable provides tangible results. Chapter 3 presents the structure of the BigDataGrapes Survey, the planning of the questionnaire, which was distributed to the end-users between the Intermediate and Summative phases (M30 - M34). Finally, the last chapter of the deliverable consists of the overall conclusions regarding the evaluation of the pilots, including discussion and suggestions that could improve their impact.

description: A data-driven chaos indicator concept is introduced to characterize the degree of chaos for nonlinear dynamical systems. The indicator is represented by the prediction accuracy of surrogate models established purely from data. It provides a metric for the predictability of nonlinear motions in a given system. When using the indicator to implement a tune-scan for a quadratic Henon map, the main resonances and their asymmetric stop-band widths can be identified. When applied to particle transportation in a storage ring, as particle motion becomes more chaotic, its surrogate model prediction accuracy decreases correspondingly. Therefore, the prediction accuracy, acting as a chaos indicator, can be used directly as the objective for nonlinear beam dynamics optimization. This method provides a different perspective on nonlinear beam dynamics and an efficient method for nonlinear lattice optimization. Applications in dynamic aperture optimization are demonstrated as real world examples.

In a lightcone description, replacing static point sources by 1-brane sources allows p^+ conservation to be maintained in their presence, which simplifies the lightcone quantization procedure. Here we calculate on-shell branion scattering amplitudes through 1 loop in lightcone gauge, and thereby resolve a puzzling ambiguity encountered in the off-shell calculations of [1]. We confirm that infrared divergences cancel in properly defined scattering probabilities. This work lays the groundwork for the incorporation of 1-brane sources in the lightcone worldsheet formalism.

description: We discuss a general combinatorial framework for operator ordering problems by applying it to the normal ordering of the powers and exponential of the boson number operator. The solution of the problem is given in terms of Bell and Stirling numbers enumerating partitions of a set. This framework reveals several inherent relations between ordering problems and combinatorial objects, and displays the analytical background to Wick's theorem. The methodology can be straightforwardly generalized from the simple example given herein to a wide class of operators.

description: We present the mass and X-ray temperature functions derived from a sample of more than 15,000 galaxy clusters of the MareNostrum Universe cosmological SPH simulations. In these simulations, we follow structure formation in a cubic volume of 500/h Mpc on a side assuming cosmological parameters consistent with either the first or third year WMAP data and gaussian initial conditions. We compare our numerical predictions with the most recent observational estimates of the cluster X-ray temperature functions and find that the low normalization cosmological model inferred from the 3 year WMAP data results is barely compatible with the present epoch X-ray cluster abundances. We can only reconcile the simulations with the observational data if we assume a normalization of the Mass-Temperature relation which is a factor of 2.5--3 smaller than our non-radiative simulations predict. This deviation seems to be too large to be accounted by the effects of star formation or cooling in the ICM, not taken into account in these simulations.

Resource management in application level message transfer systems
Creators: name: Brachman, Barry Jeffrey
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with the design of the resource management components of application level, store-and-forward message transfer systems. Although these systems have for some time been used to transport electronic mail, there has been little investigation into designs that emphasize performance and correctness aspects. Current message transfer systems are loosely structured in that there is little, if any, end-to-end resource management. The thesis begins by characterizing the message handling environment and comparing the message transfer approach to that of connection-based file transfer. Current message transfer systems have a fundamental limitation in that the largest message that can be transferred is determined by the amount of storage available at any of the intermediate hosts along the message's route. Major components of a message transfer system and design alternatives are discussed. Existing schemes that deal with solutions designed for lower networking levels are reviewed and shown to be inadequate in addressing the problems in the message handling environment. A framework for designing message transfer systems is presented. Systems adhering to the design methodology address performance issues in a structured way. Two new techniques are central to this framework: message fragmentation and the message stream. Message fragmentation is introduced as a means of delivering arbitrary size messages. The message stream abstraction is the basis of flow control and congestion control. A hierarchical technique for deadlock prevention in the message handling environment is introduced. In this method, the structured buffer pool approach is used as a top level and is integrated with a second method at the bottom level to produce a practical, deadlock-free message transfer system. Methods for providing transit buffer management and recipient buffer space allocation are discussed. A simulation study of some of the performance aspects of message streams and recipient buffer space allocation is presented.

description: The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates the introduction of non-Hermitian band topology. So far, all NHSE observations are based on one type of non-Hermitian band topology, in which the complex energy spectrum winds along a closed loop. As recently characterized along a synthetic dimension on a photonic platform, non-Hermitian band topology can exhibit almost arbitrary windings in momentum space, but their actual phenomena in real physical systems remain unclear. Here, we report the experimental realization of NHSE in a one-dimensional (1D) non-reciprocal acoustic crystal. With direct acoustic measurement, we demonstrate that a twisted winding, whose topology consists of two oppositely oriented loops in contact rather than a single loop, will dramatically change the NHSE, following previous predictions of unique features such as the bipolar localization and the Bloch point for a Bloch-wave-like extended state. This work reveals previously unnoticed features of NHSE, and provides the observation of physical phenomena originating from complex non-Hermitian winding topology.

description: The structure of the unnatural parity states of PsH, LiPs, NaPs and KPs are investigated with the configuration interaction and stochastic variational methods. The binding energies (in hartree) are found to be 8.17x10-4, 4.42x10-4, 15.14x10-4 and 21.80x10-4 respectively. These states are constructed by first coupling the two electrons into a configuration which is predominantly 3Pe, and then adding a p-wave positron. All the active particles are in states in which the relative angular momentum between any pair of particles is at least L = 1. The LiPs state is Borromean since there are no 3-body bound subsystems (of the correct symmetry) of the (Li+, e-, e-, e+) particles that make up the system. The dominant decay mode of these states will be radiative decay into a configuration that autoionizes or undergoes positron annihilation.

description: In a recent paper Flohr, Grabow and Koehn conjectured that the characters of the logarithmic conformal field theory c_{k,1}, of central charge c=1-6(k-1)^2/k, admit fermionic representations labelled by the Lie algebra D_k. In this note we provide a simple analytic proof of this conjecture.

description: Re-planning in legged locomotion is crucial to track the desired user velocity while adapting to the terrain and rejecting external disturbances. In this work, we propose and test in experiments a real-time Nonlinear Model Predictive Control (NMPC) tailored to a legged robot for achieving dynamic locomotion on a variety of terrains. We introduce a mobility-based criterion to define an NMPC cost that enhances the locomotion of quadruped robots while maximizing leg mobility and improves adaptation to the terrain features. Our NMPC is based on the real-time iteration scheme that allows us to re-plan online at $25\,\mathrm{Hz}$ with a prediction horizon of $2$ seconds. We use the single rigid body dynamic model defined in the center of mass frame in order to increase the computational efficiency. In simulations, the NMPC is tested to traverse a set of pallets of different sizes, to walk into a V-shaped chimney,and to locomote over rough terrain. In real experiments, we demonstrate the effectiveness of our NMPC with the mobility feature that allowed IIT's $87\, \mathrm{kg}$ quadruped robot HyQ to achieve an omni-directional walk on flat terrain, to traverse a static pallet, and to adapt to a repositioned pallet during a walk.
