description: An Annington-type trade model is estimated to determine the effects of government-subsidized export promotion on the demand for U.S. cotton in the Pacific Rim. Results show a significant relationship between promotion expenditures and U.S. market share in four of the six countries examined. One of the two countries exhibiting a non-significant effect had very low promotion expenditures, suggesting that a minimal level of funding may be necessary to achieve a market response. The hypothesis that export promotion has a carryover period lasting beyond one year in general is supported by the data. The question of the economic impacts of export promotion on domestic producers and taxpayers must await additional research.
title: Interpreting Volatility Shocks as Preference Shocks
Creators: name: Xu, Shaofeng
Publisher: name: Bank of Canada
Year: 2016

description: This paper examines the relationship between volatility shocks and preference shocks in an analytically tractable endogenous growth model with recursive preferences and stochastic volatility. I show that there exists an explicit mapping between volatility shocks and preference shocks, and a rise in volatility generates the same impulse responses of macroeconomic aggregates as a negative preference shock.

L’auteur montre qu’il existe une correspondence explicite entre les chocs de volatilité et les chocs de préférence, et qu’une hausse de la volatilité génère les mêmes profils de réaction d’agrégats macroéconomiques qu’un choc de préférence négatif.

The tension between gauge coupling unification, the Higgs boson mass, and a gauge-breaking origin of the supersymmetric mu-term

description: We investigate the possibility of generating the $μ$-term in the MSSM by the condensation of a field that is a singlet under the SM gauge group but charged under an additional family-independent $U(1)_X$ gauge symmetry. We attempt to do so while preserving the gauge coupling unification of the MSSM. For this, we find that SM non-singlet exotics must be present in the spectrum. We also prove that the pure $U(1)_X$ anomalies can always be solved with rationally charged fields, but that a large number of SM singlets are often required. For $U(1)_X$ charges that are consistent with an embedding of the MSSM in SU(5) or SO(10), we show that the $U(1)_X$ charges of the MSSM states can always be expressed as a linear combination of abelian subgroups of $E_6$. However, the SM exotics do not appear to have a straightforward embedding into GUT multiplets. We conclude from this study that if this approach to the $μ$-term is correct, as experiment can probe, it will necessarily complicate the standard picture of supersymmetric grand unification.

title: Broker Routing Decisions in Limit Order Markets
Creators: name: Cimon, David A.
Publisher: name: Bank of Canada
Year: 2016

description: The primary focus of this paper is to study conflict of interest in the brokerage market. Brokers face a conflict of interest when the commissions they receive from investors differ from the costs imposed by different trading venues. I construct a model of limit order trading in which brokers serve as agents for investors who wish to access equity markets. I find that brokers preferentially route marketable orders to venues with lower liquidity demand fees, driving up the execution probability at these venues and lowering adverse selection costs. When fees for liquidity supply and demand are sufficiently different, brokers route liquidity supplying orders to separate venues, where investors suffer from lower execution probability and higher costs of adverse selection.
description: Cet article étudie principalement les conflits d’intérêts dans le marché du courtage. Les courtiers se trouvent devant un conflit d’intérêts lorsque les commissions qu’ils reçoivent des investisseurs diffèrent des coûts qu’exigent les différentes plateformes de négociation. L’auteur construit un modèle de négociation d’ordres à cours limité dans lequel les courtiers servent d’intermédiaires aux investisseurs qui souhaitent accéder aux marchés boursiers. Il constate que les courtiers préfèrent acheminer les ordres négociables vers des plateformes dont les frais liés à la demande de liquidité sont moindres, ce qui augmente la probabilité d’exécution sur ces plateformes et réduit les coûts d’antisélection. Lorsque les frais associés à l’offre et à la demande de liquidité sont suffisamment différents, les courtiers transmettent les ordres favorisant l’offre de liquidité à des plateformes distinctes; ainsi, les investisseurs voient diminuer la probabilité d’exécution de leurs ordres et subissent des coûts d’antisélection plus élevés.
Combining Distributed Microphones in Smart (IoT) Environments for Acoustics Source Separation

Year: 2023

description: Nowadays, many smart devices, such as smartphones, smart watches, laptops and even smart glasses are present in environments, for example in meeting rooms. Add to this the trend towards smart homes and the Internet of Things, all of which include one or often multiple microphones. We want to share information between the microphones to perform optimal processing by the extensive spatial coverage over the room provided by these distributed microphones. However, the microphone positions are unknown, as well as the microphone relations and correlations. Our solution is to cluster the microphones with respect to their underlying dominant sources. This way, we know which microphones have similar content and which microphones can help suppress the interference and noise. We show that utilising embeddings generated by neural networks designed for speaker verification work well as speaker specific features to cluster on. We additionally show that these clusters are indeed useful for subsequent speaker separation of two concurrent talkers, where the output is two individual and denoised speech signals. By sharing information between clusters, a reference of the interfering source is present which is used to suppress that component with a mask based approach, while the wanted component is constructively added with the delay and sum beamformer.

description: ALMA observations of the Sun at mm-$λ$ offer a unique opportunity to investigate the temperature structure of the solar chromosphere. In this article we expand our previous work on modeling the chromospheric temperature of the quiet Sun, by including measurements of the brightness temperature in the network and cell interiors, from high resolution ALMA images at 3 mm (Band 3) and 1.26 mm (Band 6). We also examine the absolute calibration of ALMA full-disk images. We suggest that the brightness temperature at the center of the solar disk in Band 6 is $\sim440$ K above the value recommended by White et al. (2017) and we give improved results for the electron temperature variation of the average quiet Sun with optical depth, as well as the derived spectrum at the center of the disk. We found that the electron temperature in the network is considerably lower than predicted by model F of Fontenla et al. (1993) and that of the cell interior considerably higher than predicted by model A. Depending upon the network/cell segregation scheme, the electron temperature difference between network and cell at $τ=1$ (100 GHz) is from $\sim$660 to $\sim$1550 K, compared to $\sim$3280 K predicted by the models; similarly, the $T_e$ ratio is from $\sim$1.10, to 1.24, against $\sim$1.55 of the model prediction. We also found that the network/cell $T_e(τ)$ curves diverge as $τ$ decreases, indicating an increase of contrast with height and possibly a steeper temperature rise in the network than in the cell interior.

description: While machine-learning models are flourishing and transforming many aspects of everyday life, the inability of humans to understand complex models poses difficulties for these models to be fully trusted and embraced. Thus, interpretability of models has been recognized as an equally important quality as their predictive power. In particular, rule-based systems are experiencing a renaissance owing to their intuitive if-then representation. However, simply being rule-based does not ensure interpretability. For example, overlapped rules spawn ambiguity and hinder interpretation. Here we propose a novel approach of inferring diverse rule sets, by optimizing small overlap among decision rules with a 2-approximation guarantee under the framework of Max-Sum diversification. We formulate the problem as maximizing a weighted sum of discriminative quality and diversity of a rule set. In order to overcome an exponential-size search space of association rules, we investigate several natural options for a small candidate set of high-quality rules, including frequent and accurate rules, and examine their hardness. Leveraging the special structure in our formulation, we then devise an efficient randomized algorithm, which samples rules that are highly discriminative and have small overlap. The proposed sampling algorithm analytically targets a distribution of rules that is tailored to our objective. We demonstrate the superior predictive power and interpretability of our model with a comprehensive empirical study against strong baselines.

And this is the case if and only if K^n(A) carries a divisor with vanishing Beauville-Bogomolov square.

description: Agriculture remains a major component in the North Dakota economy, yet many activities within the agricultural industry remain unquantified. The purpose of this study was to measure the economic contribution of the soybean industry to the North Dakota economy. Expenditures and returns from soybean production, grain handling, and transportation were estimated to calculate the direct economic impacts from soybean activities. Secondary economic impacts were estimated using the North Dakota Input-Output Model. Since 1995, soybean acreage in the United States has increased substantially in nontraditional row-crop regions, such as those found in some parts of North Dakota. Soybean acreage in the state has increased 135 percent since 1995, and 210 percent since 1990. The expansion of soybean production in North Dakota has been limited to the eastern half of the state, with the largest concentration of production occurring in the Red River Valley. Soybean production in North Dakota averaged 1.2 million planted acres from 1996 to 1998. Direct impacts (expenditures and returns) from soybean production averaged $184 per acre or $221 million annually from 1996 through 1998. Average direct impacts from handling soybeans at North Dakota elevators were estimated at $4.3 million annually. Transportation of soybeans to market destinations was estimated to generate $10.1 million in annual direct impacts to the state. Total direct impacts from soybean production, grain handling, and transportation were estimated at $235.4 million annually. Total annual economic impacts (direct and secondary effects) from soybean production, grain handling, and transportation were estimated at $579 million, $11.7 million, and $26.3 million, respectively. The total annual economic impact from all soybean activities was estimated at $617 million. Soybean industry activities supported 7,700 full-time secondary jobs in North Dakota. Soybean activities were also responsible for $25 million in combined property tax, sales tax, individual income tax, and corporate income tax revenues.

Eu$_{0.5}$Sr$_{1.5}$MnO$_4$ behaves like a XY spin glass with a strong basal anisotropy. Dynamical and static scalings reveal a three-dimensional phase transition near $T_g$ = 18 K, and yield critical exponent values between those of Heisenberg- and Ising-like systems, albeit slightly closer to the Ising case. Interestingly, as in the latter system, the here observed rejuvenation effects are rather weak. The origin and nature of the low temperature XY spin glass state is discussed.

title: What Fed Funds Futures Tell Us About Monetary Policy Uncertainty
Creators: name: Fontaine, Jean-Sébastien
Publisher: name: Bank of Canada
Year: 2016

description: The uncertainty around future changes to the Federal Reserve target rate varies over time. In our results, the main driver of uncertainty is a “path” factor signaling information about future policy actions, which is filtered from federal funds futures data. The uncertainty is highest when it signals a loosening cycle. The uncertainty raises the risk premium in a loosening cycle, reducing the transmission of target changes to longer maturities. Our results trace the information content of federal funds futures to hedging demand.
description: L’incertitude entourant les changements à venir du taux cible de la Réserve fédérale évolue dans le temps. D’après les résultats, le principal facteur en cause est la « trajectoire» qui se dégage des contrats à terme sur les fonds fédéraux et qui renseigne sur les actions futures de l’autorité monétaire. L’incertitude est la plus élevée lorsque la trajectoire annonce un cycle d’assouplissement. L’incertitude fait augmenter la prime de risque lors d’un cycle d’assouplissement et atténue la transmission des changements du taux cible aux contrats de plus long terme. Les résultats donnent à penser que les informations contenues dans les contrats à terme sur les fonds fédéraux proviennent des opérations de couverture.

description: Starting from a very general quantum field theory we seek to derive Poincare invariance in the limit of low energy excitations. We do not, of course, assume these symmetries at the outset, but rather only a very general second quantised model. Many of the degrees of freedom on which the fields depend turn out to correspond to a higher dimension. We are not yet perfectly successful. In particular, for the derivation of translational invariance, we need to assume that some background parameters, which a priori vary in space, can be interpreted as gravitational fields in a future extension of our model. Assuming translational invariance arises in this way, we essentially obtain quantum electrodynamics in just 3 + 1 dimensions from our model. The only remaining flaw in the model is that the photon and the various Weyl fermions turn out to have their own separate metric tensors.

description: As more applications are being moved to the Cloud thanks to serverless computing, it is increasingly necessary to support native life cycle execution of those applications in the data center. But existing systems either focus on short-running workflows (like IBM Composer or Amazon Express Workflows) or impose considerable overheads for synchronizing massively parallel jobs (Azure Durable Functions, Amazon Step Functions, Google Cloud Composer). None of them are open systems enabling extensible interception and optimization of custom workflows. We present Triggerflow: an extensible Trigger-based Orchestration architecture for serverless workflows built on top of Knative Eventing and Kubernetes technologies. We demonstrate that Triggerflow is a novel serverless building block capable of constructing different reactive schedulers (State Machines, Directed Acyclic Graphs, Workflow as code). We also validate that it can support high-volume event processing workloads, auto-scale on demand and transparently optimize scientific workflows.

description: Abstract At Linked Pasts IV in Mainz 2018, the Linked Pasts Network had a session on "Linked Data Tools and Pipelines". As a result, the LinkedPipes Working Group was born, further developed during Linked Pasts V in Bordeaux. The main goal of Linked Pipes is to semantically model pipelines for LOD related workflows. The Linked Pipes is based on a specific ontology which assumes that a tool is linked into the Linked Open Data Cloud via Wikidata. This hackathon will be a virtual discussion room for further development of the data structure and goal, and discussion of ways to participate. It is splitted into two online sessions where the community may get an introduction, try out modelling linked pipes, report challenges and problems, discuss solutions and plan the next steps. A particular emphasis should be given to the incorporation and reuse of related Linked Data vocabularies for software workflow descriptions, a connection of linked pipes to traditional modes of publication (publication workflow identifiers) and the description of provenance of data and an adequate representation of such pipes to all audiences. The results should be implemented, sketched, discussed and finally published as a working paper for documenting data workflows.

title: Bank Screening Heterogeneity
Creators: name: Duprey, Thibaut
Publisher: name: Bank of Canada
Year: 2016

description: Production efficiency and financial stability do not necessarily go hand in hand. With heterogeneity in banks’ abilities to screen borrowers, the market for loans becomes segmented and a self-competition mechanism arises. When heterogeneity increases, the intensive and extensive margins have opposite effects. Bank informational rents unambiguously decrease welfare and distort effort incentives. But the bank most efficient at screening expands its market share by competing against itself to offer effort-inducing contracts, which decreases the share of non-performing loans. A macroprudential authority acting alone reinforces this tension. Optimality is restored by targeting lending policies toward borrowers with intermediate abilities.
description: L’efficience de la production et la stabilité financière ne vont pas nécessairement de pair. Dans un contexte d’hétérogénéité entre les banques quant à leur capacité à sélectionner les entrepreneurs, il s’opère une segmentation du marché du crédit et un phénomène d’autoconcurrence apparaît. Lorsque l’hétérogénéité s’accroît, les marges intensive et extensive ont des effets opposés. Les rentes informationnelles dont bénéficient les banques diminuent sans ambiguïté le bien-être et modifient les incitations à l’effort. La banque la plus efficace en matière de sélection des entrepreneurs voit cependant sa part de marché progresser lorsqu’elle se fait concurrence à elle-même en offrant des contrats qui incitent les entrepreneurs à intensifier leurs efforts, ce qui abaisse la proportion de prêts non productifs. Une autorité macroprudentielle agissant seule renforce cette dynamique. Le rétablissement de l’optimum nécessite des mesures favorisant le crédit aux entrepreneurs ayant une capacité de réussite moyenne.

description: This paper proposes a novel power-efficient light-emitting diode (LED) placement algorithm for indoor visible light communication (VLC). In the considered model, the LEDs can be designedly placed for high power efficiency while satisfying the indoor communication and illumination requirements. This design problem is formulated as a power minimization problem under both communication and illumination level constraints. Due to the interactions among LEDs and the illumination uniformity constraint, the formulated problem is complex and non-convex. To solve the problem, we first transform the complex uniformity constraint into a series of linear constraints. Then an iterative algorithm is proposed to decouple the interactions among LEDs and transforms the original problem into a series of convex sub-problems. Then, we use Lagrange dual method to solve the sub-problem and obtain a convergent solution of the original problem. Simulation results show that the proposed LED placement algorithm can harvest 22.86% power consumption gain when compared with the baseline scheme with centrally placed LEDs.

To do so we generalize existing implementations of dynamical replica theory and cavity field techniques to systems with strongly disordered and locally tree-like interactions. We illustrate our results via application to the dynamics of e.g. $\pm J$ spin-glasses on random graphs and of the overlap in finite connectivity Sourlas codes. All results are tested against Monte Carlo simulations.

title: Quantitative Easing in a Small Open Economy: An International Portfolio Balancing Approach
Creators: name: Kabaca, Serdar
Publisher: name: Bank of Canada
Year: 2016

description: This paper studies the effects of quantitative easing (QE) in a small open economy dynamic stochastic general-equilibrium model with international portfolio balancing. Portfolios are classified as imperfectly substitutable short-term and long-term subportfolios, each including domestic and foreign bonds. Unlike in standard small open economy models, both domestic and foreign bonds may be traded internationally. The model links the domestic term premium to the global term premium, and the implication of the model on the effectiveness of QE policies in reducing the domestic term premium depends crucially on the degree of substitutability between domestic and foreign bonds. The estimated model implies that QE in small open economies is expected to be much less effective on long-term yields because of the high substitutability between home and foreign assets found in the data. In the model, this causes the effect on the exchange rate to be limited. The paper also shows that foreign investors’ access to the domestic debt market is essential when evaluating the QE policy; ignoring foreign investors’ access would mistakenly make the policy look more effective.
description: Cette étude analyse les effets de l’assouplissement quantitatif dans un modèle d’équilibre général dynamique et stochastique adapté à une petite économie ouverte qui inclut des rééquilibrages de portefeuilles internationaux. Les portefeuilles sont classés comme des sous-portefeuilles de court et de long terme non parfaitement substituables, chacun comportant des obligations nationales et étrangères. Contrairement aux modèles standards de petite économie ouverte, les obligations nationales et étrangères peuvent faire l’objet d’échanges internationaux. Le modèle lie la prime de terme nationale à la prime de terme mondiale, et les résultats du modèle en ce qui concerne l’efficacité des politiques d’assouplissement quantitatif à réduire la prime de terme nationale dépendent fortement du degré de substituabilité entre les obligations nationales et étrangères. Le modèle estimé implique que l’assouplissement quantitatif dans les petites économies ouvertes devrait avoir une efficacité beaucoup moindre sur les rendements à long terme en raison de la grande substituabilité entre les actifs nationaux et étrangers observée dans les données. Dans le modèle, l’incidence sur le taux de change s’en trouve ainsi limitée. L’étude montre également que l’accès des investisseurs étrangers au marché intérieur de titres d’emprunt constitue un facteur essentiel à considérer lorsqu’on évalue la politique d’assouplissement quantitatif : ignorer ce facteur ferait faussement paraître la politique plus efficace.

At present fewer members of this younger generation are becoming involved in agriculture than in years past. To investigate the current barriers to entry as well as possible solutions to them a telephone survey was conducted with a group of 35 farmers who had started farming within the last 10 years. The findings indicate that low returns on agricultural productions combined with high capital investment requirements and limited land availability are the primary barriers to entry as well as expansion. Two thirds of the group reported having good access to financing in the startup period. Half of the producers also indicated that either their spouse, themselves or both were working off the farm at least part time to provide extra cash flow to cover the financing charges for their capital asset purchases. Financial management was the top ranked farm management competency followed by production techniques and a virtual tie between commodity marketing and risk management. Two thirds of the group had received encouragement from their parents to begin farming and perhaps more importantly three quarters of them had received one or more types of assistance from their family. 91% of the producers could clearly identify emerging opportunities in the industry and just over half of the producers were either planning for or already moving into these areas. The attitudes expressed by this group indicate that they recognize the necessity for prudent financial management and are prepared to work hard to overcome the challenges in the industry.
Interaction-Induced Localization of an Impurity in a Trapped Bose Condensate

description: We study the ground state properties of a trapped Bose condensate with a neutral impurity. By varying the strength of the attractive atom-impurity interactions the degree of localization of the impurity at the trap center can be controlled. As the impurity becomes more strongly localized the peak condensate density, which can be monitored experimentally, grows markedly. For strong enough attraction, the impurity can make the condensate unstable by strongly deforming the atom density in the neighborhood of the impurity. This "collapse" can possibly be investigated in bosenova-type experiments.

Energy-Momentum Distribution in Weyl Metrics
Creators: name: Sharif, M.

Publisher: name: arXiv
Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper, we evaluate energy and momentum density distributions for the Weyl metric by using the well-known prescriptions of Einstein, Landau-Lifshitz, Papaterou and M$\ddot{o}$ller. The metric under consideration is the static axisymmetric vacuum solution to the Einstein field equations and one of the field equations represents the Laplace equation. Curzon metric is the special case of this spacetime. We find that the energy density is different for each prescription. However, momentum turns out to be constant in each case.

description: Recognizing spatial relations and reasoning about them is essential in multiple applications including navigation, direction giving and human-computer interaction in general. Spatial relations between objects can either be explicit -- expressed as spatial prepositions, or implicit -- expressed by spatial verbs such as moving, walking, shifting, etc. Both these, but implicit relations in particular, require significant common sense understanding. In this paper, we introduce the task of inferring implicit and explicit spatial relations between two entities in an image. We design a model that uses both textual and visual information to predict the spatial relations, making use of both positional and size information of objects and image embeddings. We contrast our spatial model with powerful language models and show how our modeling complements the power of these, improving prediction accuracy and coverage and facilitates dealing with unseen subjects, objects and relations.
title: Producer Heterogeneity, Value-Added, and International Trade
Creators: name: Alexander, Patrick
Publisher: name: Bank of Canada
Year: 2016

description: Standard new trade models depict producers as heterogeneous in total factor productivity. In this paper, I adapt the Eaton and Kortum (2002) model of international trade to incorporate tradable intermediate goods and producer heterogeneity in value-added productivity. In equilibrium, this yields a positive relationship between the international trade elasticity and the share of intermediate goods in production. This relationship is absent from the standard model and is driven by the extensive margin of trade. I then use cross-country sectoral data from 1995 to 2010 and estimate the trade elasticity, finding empirical support for this relationship and for the importance of the extensive margin. This model yields results that are similar to those of the standard model with respect to the overall magnitude of gains from trade. Importantly, however, whereas the standard model suggests that gains from trade are higher in sectors that use intermediate goods, I find that this is no longer true under the value-added heterogeneity model.
description: Les nouveaux modèles types de commerce extérieur représentent l’hétérogénéité des producteurs sur le plan de la productivité totale des facteurs. Dans cet article, nous adaptons le modèle de commerce international d’Eaton et Kortum (2002) pour prendre en compte les biens intermédiaires échangeables et l’hétérogénéité des producteurs dans la productivité à valeur ajoutée. En situation d’équilibre, il en résulte une relation positive entre l’élasticité des échanges internationaux et la part des biens intermédiaires dans la production. Absente du modèle type, cette relation est déterminée par la marge extensive du commerce. Nous nous servons ensuite de données sectorielles se rapportant à divers pays et couvrant la période de 1995 à 2010, et estimons l’élasticité des échanges. Nous constatons ainsi que des fondements empiriques confirment cette relation et l’importance de la marge extensive. Ce modèle génère des résultats semblables à ceux du modèle type relativement à l’ampleur globale des gains provenant des échanges. Fait important cependant, là où le modèle type indique que les gains provenant des échanges sont supérieurs dans les secteurs qui utilisent des biens intermédiaires, nous découvrons qu’il n’en va pas de même dans le modèle tenant compte de l’hétérogénéité de la productivité à valeur ajoutée.

description: One of the outcomes of the merger of the Farm Management Society of Central South Australia and AARES was a project to record the history of the Australian Farm Management Society. As part of this project it was decided to develop a bibliography of Australian Farm Management Research and Publication. It has been produced as a web site to facilitate further development. One of the problems is what to include or exclude from the bibliography. This hinges on one's definition of "Farm Management". The approach taken will be explored and progress to date reported.

description: We study the functional link between the Hurst parameter and the Normalized Total Wavelet Entropy when analyzing fractional Brownian motion (fBm) time series--these series are synthetically generated. Both quantifiers are mainly used to identify fractional Brownian motion processes (Fractals 12 (2004) 223). The aim of this work is understand the differences in the information obtained from them, if any.

Low temperature magnetization and the excitation spectrum of antiferromagnetic Heisenberg spin rings

description: Accurate results are obtained for the low temperature magnetization versus magnetic field of Heisenberg spin rings consisting of an even number N of intrinsic spins s = 1/2, 1, 3/2, 2, 5/2, 3, 7/2 with nearest-neighbor antiferromagnetic (AF) exchange by employing a numerically exact quantum Monte Carlo method. A straightforward analysis of this data, in particular the values of the level-crossing fields, provides accurate results for the lowest energy eigenvalue E(N,S,s) for each value of the total spin quantum number S. In particular, the results are substantially more accurate than those provided by the rotational band approximation. For s <= 5/2, data are presented for all even N <= 20, which are particularly relevant for experiments on finite magnetic rings. Furthermore, we find that for s > 1 the dependence of E(N,S,s) on s can be described by a scaling relation, and this relation is shown to hold well for ring sizes up to N = 80 for all intrinsic spins in the range 3/2 <= s <= 7/2. Considering ring sizes in the interval 8 <= N <= 50, we find that the energy gap between the ground state and the first excited state approaches zero proportional to 1/N^a, where a = 0.76 for s = 3/2 and a = 0.84 for s = 5/2. Finally, we demonstrate the usefulness of our present results for E(N,S,s) by examining the Fe12 ring-type magnetic molecule, leading to a new, more accurate estimate of the exchange constant for this system than has been obtained heretofore.
