description: The global food marketing network is being constantly reshaped, providing opportunities and challenges to the use of information and communication technology (ICT) to develop international trade in food products. ICT is likely to be especially important for food products such as fresh fruit and vegetables that are differentiated and sensitive to timeliness in supply, possess varied quality dimensions, and involve considerable supply accumulation and assortment. Digital ICT (Internet and mobile phones), in particular, is expected to facilitate international trade and encourage efficiency in the fruit and vegetables marketing system in two main ways. First, it reduces communication and search costs through cheaper and more effective media. Second, it improves market information and corrects information externalities along the supply chain, by promoting greater price transparency and enabling consumer preferences and tastes to be more precisely met. We employed a gravity model of international trade to test the hypothesis that ICT positively affects bilateral international trade in fruit and vegetables between member Asia-Pacific Economic Cooperation (APEC) economies in the period from 1997 to 2006. Explanatory variables include the usage of the Internet, mobile telephones and fixed telephone lines, and a broad range of factors that might determine the value of bilateral trade such as income per capita, population, distance between trading partners and common language. A Poisson pseudo-maximum likelihood model was estimated in order to handle zero trade observations and reduce biases caused by heteroskedasticity. Empirical results were not quite as expected, with relatively minor impact of digital ICT. They suggest that using digital ICT has significant positive effects on trade in fruit and vegetables between APEC countries only for the Internet in exporting countries. A stronger positive impact was discerned for the traditional form of ICT, fixed telephone lines in exporting importing countries. Nevertheless, fostering the development of digital ICT infrastructure and its diffusion should make exporters in APEC countries more competitive in the fruit and vegetables supply chain through the Internet effect, and boost their trade values in these products.

description: Driven-dissipative phase transitions are currently a topic of intense research due to the prospect of experimental realizations in quantum optical setups. The most paradigmatic model presenting such a transition is the Kerr model, which predicts the phenomenon of optical bistability, where the system may relax to two different steady-states for the same driving condition. These states, however, are inherently out-of-equilibrium and are thus characterized by the continuous production of irreversible entropy, a key quantifier in thermodynamics. In this paper we study the dynamics of the entropy production rate in a quench scenario of the Kerr model, where the external pump is abruptly changed. This is accomplished using a recently developed formalism, based on the Husimi $Q$-function, which is particularly tailored for driven-dissipative and non-Gaussian bosonic systems [Phys. Rev. Res. 2, 013136 (2020)]. Within this framework the entropy production can be split into two contributions, one being extensive with the drive and describing classical irreversibility, and the other being intensive and directly related to quantum fluctuations. The latter, in particular, is found to reveal the high degree of non-adiabaticity, for quenches between different metastable states.

description: A multi-species reactive transport model based on the sequential non-iterative approach is employed to investigate two major stages involved in artificial pit experiments of stainless steel: I. Stable pitting under a salt film and II. Film-free dissolution that transitions to repassivation. Data of current density and electrical potential obtained from rapid polarization scans of pits with different depths are utilized to calibrate the elapsed time and the electrode kinetics of each stage. The local chemistry near the base of pits at different temperature and bulk concentrations is simulated to determine several critical electrochemical factors at saturation and repassivation.

description: As food is an experience good, the market for restaurant meals is a market where the cost of acquiring information regarding quality is relatively high. In such markets consumers often turn to reputation measures to guide purchase decisions. As Australia does not have a longstanding cuisine style of its own, and given Australia has been open to substantial immigration inflows since federation, it represents an especially appropriate market to study regarding the impact of individual restaurant reputation and collective cuisine reputation on meal prices. The following study uses the hedonic price approach to investigate the implicit price of individual reputation indicators, cuisine type reputation indicators, and other objective indicators in the market for restaurant meals. The empirical findings presented suggest that both individual restaurant reputation and cuisine type reputation are important. Other important factors are shown to include the quality of the restaurant wine list, the availability of private dining rooms, and whether or not there is an outdoor dining option.
Evidence of price premiums for non-GM grains in world markets

description: World markets for a number of grains (soybeans, corn, canola and cottonseed) have become differentiated into GM, certified non-GM and organic segments, which has created opportunities and challenges for grain market participants. This paper summarises the evidence to date on the extent of price premiums for non-GM products throughout the world. A broad economic framework is employed to explain the observed pattern of price premiums. The key conclusion of the analysis is that world grains markets for which there are GM variants are dominated by GM grains, but there are niches for certified non-GM and organically produced grains, for which price premiums are paid. With some certified non-GM grains for a specific purpose, price premiums appear to be increasing. Apart from consumer attitudes, the key drivers of price premiums are mandatory labelling of GM products in some key grain consuming countries (particularly high income countries), higher production costs for non-GM crops and the cost of identity preservation.

description: Tick fever is a significant disease of cattle in Australia with up to 7 million animals potentially at risk. It is a serious, often fatal complex of diseases caused by one or more of the tick-borne parasites Babesia bovis, Babesia bigemina and Anaplasma marginale. The Tick Fever Centre (TFC) operates as a unit located within Biosecurity Queensland of the Queensland Primary Industries and Fisheries (QPIF), Department of Employment, Economic Development and Innovation (DEEDI). It was established at Wacol in 1966 to specifically develop and produce an effective vaccine for the control of tick fever. It currently supplies an average of 850 000 doses each year with 95 per cent used within Queensland (QPIF 2009). One purpose of the evaluation was to identify the economic benefits provided by the ongoing provision of the tick fever vaccine. The measureable economic benefits accruing to the TFC are mainly due to potential reductions in the rate of mortality incurred in the northern beef herd. The TFC provides a significant and positive economic benefit to the Queensland and northern beef industry. Even though a number of identifiable economic and social benefits have proven difficult to measure accurately, they do exist and should be seen as adding considerably to the economic benefits quantified in this evaluation.

description: During an infectious disease outbreak, biases in the data and complexities of the underlying dynamics pose significant challenges in mathematically modelling the outbreak and designing policy. Motivated by the ongoing response to COVID-19, we provide a toolkit of statistical and mathematical models beyond the simple SIR-type differential equation models for analysing the early stages of an outbreak and assessing interventions. In particular, we focus on parameter estimation in the presence of known biases in the data, and the effect of non-pharmaceutical interventions in enclosed subpopulations, such as households and care homes. We illustrate these methods by applying them to the COVID-19 pandemic.

description: Recent work suggests that the cosmic ray spectrum may be dominated by Galactic sources up to ~10^{17.5} eV, and by an extra-Galactic component beyond, provided this latter cuts off below the transition energy. Here it is shown that this cut-off could be interpreted in this framework as a signature of extra-galactic magnetic fields with equivalent average strength B and coherence length l_c such that B\sqrt{l_c} ~ 2-3.10^{-10} G.Mpc^{1/2}, assuming l_c < r_L (Larmor radius at 10^{17} eV) and continuously emitting sources with density 10^{-5}/Mpc^3. The extra-Galactic flux is suppressed below 10^{17} eV as the diffusive propagation time from the source to the detector becomes larger than the age of the Universe.

description: Although there has been much writing about ecosystem services in the last decade, there has been insufficient which clearly elucidates their value. Rather, much of the writing has been classificatory rather than analytical (e.g. the Millennium Ecosystem Assessment, Total Economic Value (TEV), and environmental accounting) and has tended to complicate rather than enlighten. Further, these classification systems are not necessarily internally consistent, nor consistent with each other. There is no systematic analysis of what economic values to report within these frameworks although the SEEA would account in value added terms, consistent with a national accounting framework, and TEV focuses on economic surpluses but is often inter-temporally muddled. This paper explores the necessary modelling that is required to properly identify the value of ecosystem services, and to distinguish them from "supporting" biophysical processes that only have indirect and derivative anthropogenic values. The paper also explores the limitations of environmental accounting - comparable to national accounting - as policy-relevant analysis.
Caravaggio’s "Crucifixion of St. Andrew" : from the abstraction of the law to the afflicted body
Creators: name: Karabeg, Jasmina
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the "Crucifixion of St. Andrew" (1607) painted by Michelangelo Merisi da Caravaggio (1573-1610) during his first sojourn in Naples. This painting was probably commissioned by Conde de Benavente, who was viceroy o f Neapolitan kingdom, at this time part of the Spanish imperial state. The unusual choice o f Latin cross depicted in this painting links the image to the debates about Andrew's martyrdom that circulated at the end of sixteenth and the beginning o f seventeenth centuries, especially through the writing of Justus Lipsius. Seeking to mark the presence of Spanish authority through the veneration of Andrew, a saint related both to the royal family and to local sites and practices of worship, the image produces a site of exchange between the space of Neapolitan streets and the realm of sacred representation. However, this exchange with the space of the street gives new vectors of meaning to the historia of Andrew's death. As this apocryphal story provides the account of the sudden paralysis of the executioner's body, and through this physical immobility points to the suspension of executive power, the link to the urban space of Naples produces dangerous ambiguities of meaning. These ambiguities are concentrated in the figure of the woman with the goitre, depicted watching the crucifixion and as the only protagonist who fully understands the significance of this event. The materiality of the woman's body inscribes her as a migrant to the city, linking her to the spaces of the street and the market. It is precisely these volatile spaces that presented an uncontrollable threat of riots. My thesis examines these multiple conjunctions of the image in relation to the threat of riot, which indeed regularly occurred in Naples. Both the requests for institutional reforms in Naples, often linked to the uprisings in the city, and the Spanish political doctrine found their bases in ancient philosophy. While the formulations of Spanish statecraft sought to contain this thought and enable its deployment by the state, its links with the uprisings demonstrate forcefully the inability of such containment. I conclude that Caravaggio's painting shows similar disjunctures, producing a highly ambiguous narrative, which displaces urban conflicts into the realm o f religious painting.

description: This paper reports research seeking to understand the economic implications for central Queensland graziers of participating in a carbon trading scheme and to measure the likely participation of graziers in an emissions trading scheme under various market design scenarios. An initial desktop study was undertaken to compare an enterprise which produced only cattle to one which produced cattle and sequestered carbon. The findings from this analysis were used to inform the design of an experimental auction to test alternative carbon trading scenarios. An experimental workshop was conducted at seven locations across central Queensland with a range of beef producers, extension officers and consultants. Participants were presented with a scenario in which they had the choice of maintaining current management practices against altering management practices to reduce beef production and enter into a carbon sequestration contract (CSC). They were asked at what price they would enter into a CSC and how that price and likelihood of participating would change under a range of alternative contract conditions. The results of the experimental auctions found significantly higher than breakeven prices for carbon would be required before landholders would offer land as a carbon offset. Participation rates were influenced by price and also the carbon contract rules. Five rule changes were trialled and all were found to have a significant impact on reducing participation and increasing required payment levels.

description: Edge networking is a complex and dynamic computing paradigm that aims to push cloud resources closer to the end user improving responsiveness and reducing backhaul traffic. User mobility, preferences, and content popularity are the dominant dynamic features of edge networks. Temporal and social features of content, such as the number of views and likes are leveraged to estimate the popularity of content from a global perspective. However, such estimates should not be mapped to an edge network with particular social and geographic characteristics. In next generation edge networks, i.e., 5G and beyond 5G, machine learning techniques can be applied to predict content popularity based on user preferences, cluster users based on similar content interests, and optimize cache placement and replacement strategies provided a set of constraints and predictions about the state of the network. These applications of machine learning can help identify relevant content for an edge network. This article investigates the application of machine learning techniques for in-network caching in edge networks. We survey recent state-of-the-art literature and formulate a comprehensive taxonomy based on (a) machine learning technique (method, objective, and features), (b) caching strategy (policy, location, and replacement), and (c) edge network (type and delivery strategy). A comparative analysis of the state-of-the-art literature is presented with respect to the parameters identified in the taxonomy. Moreover, we debate research challenges and future directions for optimal caching decisions and the application of machine learning in edge networks.

description: Productivity and efficiency improvements in agriculture have recently been targeted as Federal Government priorities in Australia. This research examined a dataset of 116 broad-acre beef enterprises from Queensland who participated in a program, Profit Probe, developed to improve management and profitability of enterprises. The aim of this research was to identify the sources, if any, of productivity growth for this sample of enterprises. Two potential sources of productivity growth were identified: 1. Technological progress involving a contraction (expansion) of the cost (output) frontier, and; 2. Efficiency improvements involving a convergence of the average production function toward the frontier. Given these two potential sources of productivity growth, the Stochastic Frontier Analysis approach was ideally suited to discern and measure technological change and efficiency change. Changes over time were observable due to the unbalanced panel nature of the data with 116 enterprises observed over a range of years from 1999 to 2008. A Cobb-Douglas functional form for the cost function was estimated following testing of the Translog form which showed higher order terms were not significant. An input oriented minimum cost frontier was chosen over the output oriented production frontier approach due to the consideration that output decisions were largely exogenous whilst input decisions were endogenous. Deterministic predictors of inefficiency were included using the panel inefficiency effects frontier of Battese and Coelli. There was no evidence of technological progress in the ten years from 1999 to 2008 for this sample of enterprises. There was however evidence of efficiency improvements despite preexisting high efficiency levels. In particular there was evidence that the Profit Probe program significantly contributed to efficiency improvements for participating firms with improvements continuing with repeated participation in the program. Additionally cost efficiency was shown to be an important component of profit maximisation but most likely was not a sufficient condition with output prices, as a quality and market indicator, being highly significantly related to profit levels.

REVENUE FUNDS COUNTERACT THE DETERMINANTS OF DUTCH DISEASE: LESSONS FOR WESTERN AUSTRALIA

Year: 2010
Subjects: Resource /Energy Economics and Policy

description: Dutch disease occurs when government revenue from a booming non-renewable natural resource export sector is spent on recurrent domestic activities. Dutch disease amplifies the cyclical influence of commodity prices and inflicts adjustment costs on the economy through movements in the exchange rate. Revenue funds, such as revenue stabilisation funds or sovereign wealth funds, can help avoid this problem by either investing revenue abroad until downturns or holding revenue abroad indefinitely. Through an investigation of six open, natural resource exporting countries, revenue funds were found to delink exchange rate movements from the terms of trade. Although it is unlikely that revenue funds are the sole cause of this effect, revenue funds are considered a useful tool for, but not essential to, responsible fiscal management. Western Australia has been found to have Dutch disease. Recurrent government expenditure is vulnerable to decreases in royalty receipts. High levels of mineral exports are partly responsible for the high Australian dollar. Revenue funds are a potential policy tool if the Western Australian government decides to limit the impact of export prices on Australia’s exchange rate. As this is unlikely to be an objective for a state government, it should instead be seen as an added benefit to countercyclical or sustainable fiscal policies. In this case, only a sovereign wealth fund is considered appropriate at the state level and could be used to manage royalties sustainably, reduce movements in Australia’s exchange rate and gain greater fiscal autonomy for the states.

As an example we give the detailed settings for a simultaneous measurement of all four Bell States for an arbitrary two-photon polarization state, which is impossible with linear optics alone.

description: The NSW Cap & Pipe the Bores Program is a jointly funded Commonwealth and State initiative that operates within the Australian Government’s Great Artesian Basin Sustainability Initiative (GABSI) framework. The third five-year period of GABSI was due to commence on 1st July 2009. This economic study of changes in landholder water management under the Cap & Pipe the Bores program was undertaken to inform the development of GABSI phase 3 policy in NSW. The study consisted of a small number of case studies of farming enterprises across the Great Artesian Basin Groundwater Management Zones of Surat South, Surat East, Surat West, Warrego and Central in NSW. The apparent landholder economic feasibility of the program was dependent on individual farm characteristics as much as location to the bore and geographic location within the GAB.

description: Fake news detection is a very prominent and essential task in the field of journalism. This challenging problem is seen so far in the field of politics, but it could be even more challenging when it is to be determined in the multi-domain platform. In this paper, we propose two effective models based on deep learning for solving fake news detection problem in online news contents of multiple domains. We evaluate our techniques on the two recently released datasets, namely FakeNews AMT and Celebrity for fake news detection. The proposed systems yield encouraging performance, outperforming the current handcrafted feature engineering based state-of-the-art system with a significant margin of 3.08% and 9.3% by the two models, respectively. In order to exploit the datasets, available for the related tasks, we perform cross-domain analysis (i.e. model trained on FakeNews AMT and tested on Celebrity and vice versa) to explore the applicability of our systems across the domains.

The paper used the research “Family Farm, Local Development and Pluriactivity” (UFRGS/ UFPel/CNPq-2003) that propitiated the formation of a database with information on the dynamics of the family farm in four areas different from the geography of the Rio Grande do Sul, your sources and types of income, among these the self-consumption. To bring this debate means to retake a theme little discussed until then, and that, although marginalized or considered without importance, it develops important role as income non monetary, strengthens the food security and it penetrates spheres of the sociability and social identity. Besides the introduction, is presented the role of the self-consumption in the family farm, the calculation of the self-consumption production, discussion of the objectives and results, and final considerations. The results demonstrate that the self-consumption production is an appealing strategy for the family units and it differs in agreement with the dynamics of the family farm. It differentiates this expresses in relative values (%) and in the number of establishments belonging to differentiated strata of self-consumption, and a little in the types of foods produced for this end, being observed a homogeneity of the alimentary habits.

description: In view of extending gauge/gravity dualities with flavour beyond the probe approximation, we establish the gravity dual description of mesons for a three-dimensional super Yang-Mills theory with fundamental matter. For this purpose we consider the fully backreacted D2/D6 brane solution of Cherkis and Hashimoto in an approximation due to Pelc and Siebelink. The low-energy field theory is the IR fixed point theory of three-dimensional N=4 SU(N_c) super Yang-Mills with N_f fundamental fields, which we consider in a large N_c and N_f limit with N_f/N_c finite and fixed. We discuss the dictionary between meson-like operators and supergravity fluctuations in the corresponding near-horizon geometry. In particular, we find that the mesons are dual to the low-energy limit of closed string states. In analogy to computations of glueball mass spectra, we calculate the mass of the lowest-lying meson and find that it depends linearly on the quark mass.

description: The impact of 400 keV $Ar^+$ ion irradiation on the magnetic and electrical properties of in-plane magnetized magnetic tunnel junction (MTJ) stacks was investigated by ferromagnetic resonance, vibrating sample magnetometry and current-in-plane tunneling techniques. The irradiation-induced changes of the magnetic anisotropy, coupling energies and tunnel magnetoresistance (TMR) exhibited a correlated dependence on the ion fluence, which allowed us to distinguish between two irradiation regimes. In the low-fluence regime, $Φ < 10^{14} cm^{-2}$, the parameters required for having a functioning MTJ were preserved: the anisotropy of the FeCoB free layer (FL) was weakly modulated following a small decrease in the saturation magnetization $M_S$; the TMR decreased continuously; the interlayer exchange coupling (IEC) and the exchange bias (EB) decreased slightly. In the high-fluence regime, $Φ > 10^{14} cm^{-2}$, the MTJ was rendered inoperative: the modulation of the FL anisotropy was strong, caused by a strong decrease in $M_S$, ascribed to a high degree of interface intermixing between the FL and the Ta capping; the EB and IEC were also lost, likely due to intermixing of the layers composing the synthetic antiferromagnet; and the TMR vanished due to the irradiation-induced deterioration of the MgO barrier and MgO/FeCoB interfaces. We demonstrate that the layers surrounding the FL play a decisive role in determining the trend of the magnetic anisotropy evolution resulting from the irradiation, and that an ion-fluence window exists where such a modulation of magnetic anisotropy can occur, while not losing the TMR or the magnetic configuration of the MTJ.

description: We continue our investigation into the nonlinear evolution of the Goldreich-Schubert-Fricke (GSF) instability in differentially rotating radiation zones. This instability may be a key player in transporting angular momentum in stars and giant planets, but its nonlinear evolution remains mostly unexplored. In a previous paper we considered the equatorial instability, whereas here we simulate the instability at a general latitude for the first time. We adopt a local Cartesian Boussinesq model in a modified shearing box for most of our simulations, but we also perform some simulations with stress-free, impenetrable, radial boundaries. We first revisit the linear instability and derive some new results, before studying its nonlinear evolution. The instability is found to behave very differently compared with its behaviour at the equator. In particular, here we observe the development of strong zonal jets ("layering" in the angular momentum), which can considerably enhance angular momentum transport, particularly in axisymmetric simulations. The jets are, in general, tilted with respect to the local gravity by an angle that corresponds initially with that of the linear modes, but which evolves with time and depends on the strength of the flow. The instability transports angular momentum much more efficiently (by several orders of magnitude) than it does at the equator, and we estimate that the GSF instability could contribute to the missing angular momentum transport required in both red giant and subgiant stars. It could also play a role in the long-term evolution of the solar tachocline and the atmospheric dynamics of hot Jupiters.

description: Transactions among agribusiness agents are not exclusively carried out on the market, being also governed by alternative types of institutional arrangements, some of which determined upon contractual agreement. In the fertilizers sector, the companies intensified the offer of input packages to farmers, more specifically to soybean producers, object of this article. In order to acquire the fertilizers, these producers may choose to use their own financial resources, to obtain resources through financing with third parties, or they may recur to the said packages, which include soybean and financial resources in addition to the fertilizers, referred by the soybean producers to as “exchange”, since they acquire fertilizer paying with soybean for future delivery. Thus, the following questions motivate this work: What are the factors that determine the selection of the soybean producer between alternative arrangements for the acquisition of fertilizers? Two hundred interviews were conducted with soybean producers in the States of Goiás and Mato Grosso. To conclude, packages or arrangements as bundling may be stimulated by reasons of efficiency, with transaction costs economy as one of these possible reasons. Risk aversion and trust leads to the use of the exchange arrangement. Finally, in relation to the scale, largest soybean producers use the arrangement exchange in a great deal, differently from what was expected.

description: Complex networks are characterized by several topological properties: degree distribution, clustering coefficient, average shortest path length, etc. Using a simple model to generate scale-free networks embedded on geographical space, we analyze the relationship between topological properties of the network and attributes (fitness and location) of the vertices in the network. We find there are two crossovers for varying the scaling exponent of the fitness distribution.

Towards a New Democracy: Consensus Through Quantum Parliament

description: We compare different actual forms of democracy and analyse in which way they are variations of a 'natural consensus decision process'. We analyse how 'consensus decision followed by majority voting' is open to 'false play' by the majority, and investigate how other types of false play appear in alternative types of democratic decision procedures. We introduce the combined notion of 'quantum parliament' and 'quantum decision procedure', and prove it to be the only one, when applied after consensus decision, that is immune to false play.

description: The objective of the present paper is to examine the behavior and the structure of the export sector of the economy of Rio Grande do Norte from 1996 to 2006, and to identify the products of revealed comparative advantage. The paper also seeks to measure levels of export concentration of products and destination markets, types of trade, and export sectors that show strength. To achieve the objectives of the paper, the intra-industry indices of GRUBEL AND LLOYD (1975) and the indices of revealed comparative advantage of BALASSA (1965) e LAURSEN (1998) were used. The indexes of product concentration and export destination were obtained through the Gini-Hirchmna coefficient. The data was taken from the ALICEWEB system of the Ministry of Development, Industry and Trade – MDIC. The results revealed a high concentration of few primary products and destination markets, along with weak participation in the export of manufactured products. The study points out that the international trade of the State of Rio Grande do Norte is basically inter-industrial; that is, it exports primary products and imports manufactured products, characteristic of the Herckscher-Ohlin trade type. Among the group of products with intraindustrial trade, the cotton group stands out, showing the importance of the textile sector in the state’s economy.

description: This paper uses an unprecedentedly rich data set to estimate the cost of agricultural cargo preference (ACP) restrictions on United States food aid programs and to document some of the competitiveness and national security impacts. ACP cost US taxpayers $140 million in 2006, 46 percent above competitive freight costs. The unreimbursed cost of ACP to food aid agencies roughly equals USAID’s non‐emergency food aid to Africa. Furthermore, 70 percent of ACP vessels did not satisfy criteria to be deemed militarily useful and vessels ultimately owned by foreign corporations carried a large share of ACP food aid shipments.

description: Sparse Identification of Nonlinear Dynamics (SINDy) is a method of system discovery that has been shown to successfully recover governing dynamical systems from data (Brunton et al., PNAS, '16; Rudy et al., Sci. Adv. '17). Recently, several groups have independently discovered that the weak formulation provides orders of magnitude better robustness to noise. Here we extend our Weak SINDy (WSINDy) framework introduced in (arXiv:2005.04339) to the setting of partial differential equations (PDEs). The elimination of pointwise derivative approximations via the weak form enables effective machine-precision recovery of model coefficients from noise-free data (i.e. below the tolerance of the simulation scheme) as well as robust identification of PDEs in the large noise regime (with signal-to-noise ratio approaching one in many well-known cases). This is accomplished by discretizing a convolutional weak form of the PDE and exploiting separability of test functions for efficient model identification using the Fast Fourier Transform. The resulting WSINDy algorithm for PDEs has a worst-case computational complexity of $\mathcal{O}(N^{D+1}\log(N))$ for datasets with $N$ points in each of $D+1$ dimensions (i.e. $\mathcal{O}(\log(N))$ operations per datapoint). Furthermore, our Fourier-based implementation reveals a connection between robustness to noise and the spectra of test functions, which we utilize in an \textit{a priori} selection algorithm for test functions. Finally, we introduce a learning algorithm for the threshold in sequential-thresholding least-squares (STLS) that enables model identification from large libraries, and we utilize scale-invariance at the continuum level to identify PDEs from poorly-scaled datasets. We demonstrate WSINDy's robustness, speed and accuracy on several challenging PDEs.
