description: We have developed a compact partially ferromagnetic electromagnet to produce a Ioffe-Pritchard trap for neutral atoms. Our structure permits strong magnetic confinement with low power consumption. Compared to the previous iron-core electromagnet, it allows for easy compensation of remnant fields and very high stability, along with cost-effective realization and compactness. We describe and characterize our apparatus and demonstrate trapping and cooling of Rb 87 atoms to quantum degeneracy. Pure Bose-Einstein condensates containing 10^6 atoms are routinely realized on a half-minute cycle. In addition we test the stability of the magnetic trap by producing atom lasers.

description: Tracking mouse cursor movements can be used to predict user attention on heterogeneous page layouts like SERPs. So far, previous work has relied heavily on handcrafted features, which is a time-consuming approach that often requires domain expertise. We investigate different representations of mouse cursor movements, including time series, heatmaps, and trajectory-based images, to build and contrast both recurrent and convolutional neural networks that can predict user attention to direct displays, such as SERP advertisements. Our models are trained over raw mouse cursor data and achieve competitive performance. We conclude that neural network models should be adopted for downstream tasks involving mouse cursor movements, since they can provide an invaluable implicit feedback signal for re-ranking and evaluation.

description: This report's intent is to analyze the 2002 US "Farm Bill" to determine whether it is production and trade distorting, and how it will affect commodity markets as well as how it will affect Canadian agri-food. The objectives are to: · To explain the producer subsidy programs and how payments under these programs will be calculated; · To explain other provisions in the Farm Bill that are of interest to the Canadian agriculture and agri-food industry; · To discuss the implications of the producer subsidy programs for US producers' decisions to grow the major commodities and pulses, and the likely implications of those decisions for market prices; · To discuss the implications of other Farm Bill provisions, including trade and conservation programs, and country of origin labeling; · To discuss the implications of the Farm Bill for the current round of WTO negotiations; and · To provide some initial thoughts on how governments and firms in Canada and other countries might respond to the Farm Bill. To accomplish the objectives, we provide a thorough description of the Act and its provisions. We apply it to a fictitious 1000 acre farm in the US Midwest to show its financial consequences. We also use production costs from certain regions of the US to determine the level of incentive built into the Act.

description: Dimer models are 2-dimensional combinatorial systems that have been shown to encode the gauge groups, matter content and tree-level superpotential of the world-volume quiver gauge theories obtained by placing D3-branes at the tip of a singular toric Calabi-Yau cone. In particular the dimer graph is dual to the quiver graph. However, the string theoretic explanation of this was unclear. In this paper we use mirror symmetry to shed light on this: the dimer models live on a T^2 subspace of the T^3 fiber that is involved in mirror symmetry and is wrapped by D6-branes. These D6-branes are mirror to the D3-branes at the singular point, and geometrically encode the same quiver theory on their world-volume.

description: Braiding Majorana zero-modes around each other is a promising route towards topological quantum computing. Yet, two competing maxims emerge when implementing Majorana braiding in real systems: On the one hand, perfect braiding should be conducted adiabatically slowly to avoid non-topological errors. On the other hand, braiding must be conducted fast such that decoherence effects introduced by the environment are negligible, which are generally unavoidable in finite-size systems. This competition results in an intermediate time scale for Majorana braiding that is optimal, but generally not error-free. Here, we calculate this intermediate time scale for a T-junction of short one-dimensional topological superconductors coupled to a bosonic bath that generates fluctuations in the local electric potential, which stem from, e.g., environmental photons or phonons of the substrate. We thereby obtain boundaries for the speed of Majorana braiding with a predetermined gate fidelity. Our results emphasize the general susceptibility of Majorana-based information storage in finite-size systems and can serve as a guide for determining the optimal braiding times in future experiments.

description: Trade liberalization has been received around the world with mixed emotions. The completion of the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) in December 1993 brought conversations about international trade into the conversation of the general public in a significant way for the first time. What is most important, individuals against or concerned about increased global trade have successfully organized themselves into forces of recognition, taking the conversations about trade from the back rooms into the streets. This was manifest at the Third, or Seattle, Ministerial Conference which was aimed at ushering in the Next Round of Trade Negotiations under the World Trade Organization (WTO) in December 1999. During the volatile week in Seattle in December 1999, the focus of the media was primarily on the demonstrations and riots on the streets, with little or no coverage of the activities going on in the meetings at the Ministerial Conference. The WTO was unable to make a Ministerial Declaration to launch the next round of trade negotiations, leading some to think that any international trade liberalization effort has been derailed because of the demonstrations and riots. A number of questions emerge as a result of the events emanating from the Seattle Ministerial Conference, but three of these are of specific interest to this author: 1. What really happened at the Seattle Ministerial and why? 2. What are the implications of what happened to global trade negotiations in the future? 3. Why should Canada care? This paper addresses the above questions, looking at the issues leading up to the Ministerial, the structure of the Ministerial agenda and the positions tabled by various countries in an attempt to understand the outcome of the Seattle Ministerial. It also looks at the changes in the membership of the WTO and the negotiation processes and how these affect future global trade negotiations. We also assess the increasing importance of trade to Canada, arguing that there is an important role for Canada in the current negotiation to ensure its successful conclusion. The layout of the paper is as follows. The next section presents a brief summary of the built-in agenda that was agreed to at the end of the Uruguay Round, explaining the evolving nature of international trade rules and the changes that have occurred in international trade relations since the WTO came into force on January 1, 1995. The section following presents the agenda of the Seattle Ministerial, the positions on the critical subjects of negotiations - including agriculture, implementation and rules, market access - tabled by the various countries and condition that created for the ability of the Seattle Ministerial to achieve its objectives. The final section presents developments at the WTO since Seattle and what that means for Canada's agri-food industries.

description: The dielectric properties of noncrystalline hafnium silicon oxynitride (HfSiON) films with a variety of atomic compositions were investigated. The films were deposited by reactive sputtering of Hf and Si in an O, N, and Ar mixture ambient. The bonding states, band-gap energies, atomic compositions, and crystallinities were confirmed by X-ray photoelectron spectroscopy (XPS), reflection electron energy loss spectroscopy (REELS), Rutherford backscattering spectrometry (RBS), and X-ray diffractometry (XRD), respectively. The optical (high-frequency) dielectric constants were optically determined by the square of the reflective indexes measured by ellipsometry. The static dielectric constants were electrically estimated by the capacitance of Au/HfSiON/Si(100) structures. It was observed that low N incorporation in the films led to the formation of only Si-N bonds without Hf-N bonds. An abrupt decrease in band-gap energies was observed at atomic compositions corresponding to the boundary where Hf-N bonds start to form. By combining the data for the atomic concentrations and bonding states, we found that HfSiON can be regarded as a pseudo-quaternary alloy consisting of four insulating components: SiO$_2$, HfO$_2$, Si$_3$N$_4$, and Hf$_3$N$_4$. The optical and static dielectric constants for the films showed a nonlinear dependence on the N concentration, whose behavior can be understood in terms of abrupt Hf-N bond formation.

description: In beyond-Horndeski theories of gravity, the Vainshtein screening mechanism might only be partially effective inside stellar objects. This results in a modification of the pressure balance equation inside stars, often characterized by a single parameter ($Υ$) in isotropic systems. We show how to constrain such theories of modified gravity, using tidal effects. We study such effects in cataclysmic variable star binaries and numerically obtain limits on the critical masses of the donor stars, below which they are tidally disrupted, by modeling them in beyond-Horndeski theories. This is contrasted with values of the donor masses, obtained using existing observational data, by a Monte Carlo error progression method. A best fit scenario of the two yields a parametric constraint in the theories that we consider, within the approximations used. Here, we obtain the allowed range $ 0 \le Υ\le 0.47 $.

description: Physics of the low-lying and high-lying hadrons in the light flavors sector is reviewed. While the low-lying hadrons are strongly affected by both $U(1)_A$ and spontaneous $SU(2)_L \times SU(2)_R$ breakings, in the high-lying hadrons these symmetries are restored. A manifestation is a persistence of the chiral multiplet structure in both baryon and meson spectra. A fundamental origin of this phenomenon is that effects of quantum fluctuations of both quark and gluon fields must vanish at large $n$ or $J$ and a semiclassical description becomes adequate. A relation between the chiral symmetry restoration and the string picture of excited hadrons is discussed.

description: We present the largest and deepest late-time radio and millimeter survey to date of superluminous supernovae (SLSNe) and long duration gamma-ray bursts (LGRBs) to search for associated non-thermal synchrotron emission. Using the Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA), we observed 43 sources at 6 and 100 GHz on a timescale of $\sim 1 - 19$ yr post-explosion. We do not detect radio/mm emission from any of the sources, with the exception of a 6 GHz detection of PTF10hgi (Eftekhari et al. 2019), as well as the detection of 6 GHz emission near the location of the SLSN PTF12dam, which we associate with its host galaxy. We use our data to place constraints on central engine emission due to magnetar wind nebulae and off-axis relativistic jets. We also explore non-relativistic emission from the SN ejecta, and place constraints on obscured star formation in the host galaxies. In addition, we conduct a search for fast radio bursts (FRBs) from some of the sources using VLA Phased-Array observations; no FRBs are detected to a limit of $16$ mJy ($7σ$; 10 ms duration) in about 40 min on source per event. A comparison to theoretical models suggests that continued radio monitoring may lead to detections of persistent radio emission on timescales of $\gtrsim {\rm decade}$.

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: The latest solar atmosphere models include non-LTE corrections and 3D hydrodynamic convection simulations. These models predict a significant reduction in the solar metal abundance, which leads to a serious conflict between helioseismic data and the predictions of solar interiors models. We demonstrate that the helioseismic constraints on the surface convection zone depth and helium abundance combined with stellar interiors models can be used to define the goodness of fit for a given chemical composition. After a detailed examination of the errors in the theoretical models we conclude that models constructed with the older solar abundances are consistent (<2 σ) with the seismic data. Models constructed with the proposed new low abundance scale are strongly disfavored, disagreeing at the 15 σlevel. We then use the sensitivity of the seismic properties to abundance changes to invert the problem and infer a seismic solar heavy element abundance mix with two components: meteoritic abundances, and the light metals CNONe. Seismic degeneracies between the best solutions for the elements arise for changes in the relative CNONe abundances and their effects are quantified. We obtain Fe/H=7.50+/-0.045+/-0.003(CNNe) and O/H=8.86+/-0.041+/-0.025(CNNe) for the relative CNNe in the GS98 mixture. The inferred solar oxygen abundance disagree with the abundance inferred from the 3D hydro models. Changes in the Ne abundance can mimic changes in O for the purposes of scalar constraints.Models constructed with low oxygen and high neon are inconsistent with the solar sound speed profile. The implications for the solar abundance scale are discussed.

description: The dairy industry in Canada was turned on its ear by the release of the WTO decision last fall that Canada's Special Milk Classes constitute an export subsidy. Dairy processors fear the loss of established export markets. At the same time, the decision threatens the role of supply management authorities as the sole marketers of farmers' milk. Will farmers market milk for export directly to processors? What consequences could renewed marketing board involvement in exports have in the international trade arena? The industry is preparing for conflict as it reorients itself in the international market. That conflict is embedded in proposals made by some of the milk marketing agencies and by some processor members of the National Dairy Council(NDCC). Because of the immediate importance of this case and the issues it spawns, the George Morris Centre is releasing this special report. It addresses the following topics: - The nature of the challenges to the Special Milk Classes scheme - The WTO decision Implications for the dairy industry - Marketing boards' proposal for export pricing reform - NDCC proposal for export pricing reform - Evaluation of the alternatives
Nonlinear Sigma Model for a Condensate Composed of Fermionic Atoms

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: A nonlinear sigma model is derived for the time development of a Bose-Einstein condensate composed of fermionic atoms. Spontaneous symmetry breaking of a Sp(2) symmetry in a coherent state path integral with anticommuting fields yields Goldstone bosons in a Sp(2)\U(2) coset space. After a Hubbard-Stratonovich transformation from the anticommuting fields to a local self-energy matrix with anomalous terms, the assumed short-ranged attractive interaction reduces this symmetry to a SO(4)\U(2) coset space with only one complex Goldstone field for the singlett pairs of fermions. This bosonic field for the anomalous term of fermions is separated in a gradient expansion from the density terms. The U(2) invariant density terms are considered as a background field or unchanged interacting Fermi sea in the spontaneous symmetry breaking of the SO(4) invariant action and appear as coefficients of correlation functions in the nonlinear sigma model for the Goldstone boson. The time development of the condensate composed of fermionic atoms results in a modified Sine-Gordon equation.

description: One of the biggest challenges faced by food manufacturers and the agriculture and food industry in general, is the fact that many food products are mature product lines. That means that sales are essentially steady - at best. In fact by its very nature, the food industry is characterized by relatively steady growth at relatively narrow profit margins. In mature markets, competition typically takes the form of price-cutting and gains by one firm are often at the expense of another. From that point the entire product line or category can become nothing more than a commodity that is priced as low as possible and simply "milked" for whatever profits are possible. That is not an enviable position, nor is it a position that a firm can easily escape. When an example occurs in which a mature product category is revived from the mature stage, it is worth taking a close look at how it was done. Lessons learned from one firm or product category might be applied to another in order to escape the clutches of maturity and commoditization. The purpose of this note is to examine the case of Quaker Oats rice cakes and how that firm twice managed to escape the clutches of product maturity.

description: We employ mean-field, Bogoliubov, and many-body theories to study critical fluctuations in position and momentum of a Bose-Einstein condensate whose translation symmetry is spontaneously broken due to attractive interactions. In a homogeneous system, the many-body ground state of the symmetry-preserving Hamiltonian is very fragile against superposition of low-lying states, while mean-field theory predicts a stable bright soliton which spontaneously breaks translation symmetry. We show that weak symmetry-breaking perturbations cause the translation-symmetric many-body ground state to cross over to a many-body bright soliton. We argue that the center-of-mass fluctuations in the soliton state arise primarily from the depletion of the condensate to translation modes. We develop an extended mean-field theory to analytically reproduce these results obtained by the exact diagonalization method.

Functional studies of Calbindin-D28K and its role in intracellular calcium homeostasis
Creators: name: Rintoul, Gordon Leslie
Publisher: name: University of British Columbia
Year: 2009

description: Calbindin-D28k (CaBP) is a 28 kD calcium-binding protein found in specific neuronal populations in the mammalian brain. The hypothesized Ca²⁺-buffering action of CaBP is the basis of suggestions that this protein may serve to protect neurons against cell death mediated by large or prolonged increases in intracellular free Ca²⁺ concentration. However, to date, there is little direct evidence to support this hypothesis. To address this question directly, we have examined Ca²⁺-buffering by CaBP in stably transfected HEK 293 and HeLa cell lines. A variety of methods were employed to induce calcium transients, including transfection of NMD A receptors followed by activation with glutamate. In all experiments there was evidence of CaBP-mediated Ca²⁺-buffering. Moreover, when NMDAR transfected cells were exposed to excitotoxic concentrations of glutamate, cells expressing CaBP exhibited enhanced survival over controls. CaBP was unable to prevent acute necrotic cell death but significantly protected cells from delayed, presumably apoptotic cell death. To examine the potential influence of CaBP upon intracellular Ca²⁺-oscillations, stably-transfected HeLa cells were treated with histamine, while measuring intracellular Ca²⁺. The observation that CaBP flattened the profile of component Ca²⁺ peaks, coupled with data from HEK cell lines, provides unequivocal evidence that CaBP can act to buffer increases in intracellular Ca²⁺. Utilizing a novel method for resolving intracellular Ca²⁺ waves, it was found that transfection with CaBP, or loading with artificial Ca²⁺ buffers, attenuated the velocity of Ca²⁺ waves. The scope of attenuation appeared to be a function of the buffer binding kinetics. The rate of Ca²⁺-binding by CaBP was apparently too slow to influence Ca²⁺- interaction between the closely situated IP₃ receptors in initiation sites, where the faster on rate buffer BAPTA exerted a significant effect. However, both CaBP and BAPTA had significant effects upon events which were more distal to the source of Ca²⁺ release, including effects between the more sparsely distributed IP₃ receptors involved in the propagation of Ca²⁺ waves, and global changes in Ca²⁺. In view of the fact that Ca²⁺ waves and oscillations have been shown to modulate neuron development and gene expression, it is possible that the effects of CaBP may include influencing these processes.

description: The Jiangmen Underground Neutrino Observatory (JUNO) project aims at probing, at the same time, the two main frequencies of three-flavor neutrino oscillations, as well as their interference related to the mass ordering (normal or inverted), at a distance of ~53 km from two powerful reactor complexes in China, at Yangjiang and Taishan. In the latter complex, the unoscillated spectrum from one reactor core is planned to be closely monitored by the Taishan Antineutrino Observatory (TAO), expected to have better resolution (x 1/2) and higher statistics (x 30) than JUNO. In the context of neutrino energy spectra endowed with fine-structure features from summation calculations, we analyze in detail the effects of energy resolution and nucleon recoil on observable event spectra. We show that a model spectrum in TAO can be mapped into a corresponding spectrum in JUNO through appropriate convolutions. The mapping is exact in the hypothetical case without oscillations, and holds to a very good accuracy in the real case with oscillations. We then analyze the sensitivity to mass ordering of JUNO (and its precision oscillometry capabilities) assuming a single reference spectrum, as well as bundles of variant spectra, as obtained by changing nuclear input uncertainties in summation calculations from a publicly available toolkit. We show through a chi-squared analysis that variant spectra induce little reduction of the sensitivity in JUNO, especially when TAO constraints are included. Subtle aspects of the statistical analysis of variant spectra are also discussed.

description: This study examines hedging strategies for commodity processors generally and soybean crushers specifically. Processors require hedging strategies built around processing multiple batches each year. Each batch requires the purchase of inputs, transformation of inputs into outputs, and sale of the resulting output. The more batches processed, the greater the transaction frequency, the smaller each batch's size. Increased transaction frequency reduces risk because of the smaller batch size. This study distinguishes between batch (accounting) profits and periodic profits (cash flows). Traditional hedging models have focused on batch profits but we argue that hedging cash flows are also a legitimate hedging target because (a) discounted cash flow is the capital investment decision criterion, (b) costs are associated with managing working capital, (c) cash flow and profits converge in annual aggregation, and (d) stabilizing periodic cash flow stabilizes annual profits but the converse does not hold. Weekly cash and futures prices from 1990 through 2003 are used to compare averages and standard deviations of direct-hedged and unhedged profits and cash flows with transaction frequencies of 1, 2, 4, 13, 26 and 52 weeks. Our findings are as follows. (1) Increased transaction frequency reduces the variance of unhedged profits and cash flows. Two effects account for this. Both profit and cash flow risks are reduced by smaller batch size associated with increased transaction frequency but only profit risk is reduced by closer integration of input and output markets as transaction frequency increases. (2) As transaction frequency increases, the amount of hedgeable risk declines (finding 1) and the effectiveness of traditional hedges also declines. (3) Anticipatory hedging of soybean processing does not offer much risk protection. (4) Traditional hedging of batch profits tends to destabilize periodic cash flows. Several areas meriting additional investigation are also discussed.

description: Based on a sport informatics approach, this thesis aimed to digitally optimise data to evidence transitions occurring within player management decision-making processes in a professional rugby union environment. With the objective of translating the findings to sport, the first study systematically reviewed the use of Business Process Management (BPM) for improving patient management processes in healthcare. Consequently, from
the results, guidelines for using BPM to optimise data-informed player management processes were proposed. Thereafter, by using the first three stages of a BPM lifecycle (process identification, discovery and redesign), the next study utilised those prior findings to identify issues existing in the current state of an information flow pertaining to player management decision-making processes within a Gallagher Premiership rugby
union club in England. The results indicated that there was inaccessible data, unavailable data, unavailable information, information noise, incomplete decisions and no consensus for flagging players with risks. In the next experimental study, directed by the remaining three phases of the BPM lifecycle (process redesign, implementation and monitoring) and by applying innovation and design thinking approaches, a pre-post-test study design was used to examine if the inaccessibility of daily player strength and conditioning data can be optimised through digitalisation techniques. The outcomes indicated that the designed digital systems enhanced information quality, thereby, signifying an improved data to information transition. The fourth study employed consensus methods to organise practitioner judgements when flagging players with risks. Specifically, by using the expertise within the considered environment, a consensus statement, as a subjective standard was formulated to standardise judgements on the existence of peaks/troughs in external training loads experienced by
the players, identified from Global Positioning Systems (GPS) based information. The final experimental study implemented the developed standard via digitalisation techniques and evaluated the impact of it on practitioner decision-making, by detecting
the change in reliability of agreement between staff for a given decision at four time points before and after implementing the standard. The outcomes signified that practitioner agreement increased from moderate pre-standard levels to almost perfect
post-standard agreement. Thus, signifying an enhanced information to evidence transition. Overall, this thesis provides a philosophical and methodological approach to optimising data-informed player management decision-making processes in professional sport environments like rugby union.

description: We present a uniform construction of level 1 perfect crystals $\mathcal B$ for all affine Lie algebras. We also introduce the notion of a crystal algebra and give an explicit description of its multiplication. This allows us to determine the energy function on $\mathcal B \otimes \mathcal B$ completely and thereby give a path realization of the basic representations at $q=0$ in the homogeneous picture.

description: This study analyzes the potential risk reduction gains from naive diversification (equal-weighting) among market advisory services for corn and soybeans. The total possible decrease in risk through naive diversification is small, mainly because advisory prices are highly correlated on average. Moreover, since marginal risk reduction benefits decrease rapidly with size, and the cost of holding the portfolios increases linearly due to services' subscription fees, it is optimal to limit portfolio size to a few advisory programs. Based on certainty equivalent measures and two representative risk aversion levels, preferred portfolio sizes are between one and three services. Overall, there does not appear to be strong justification for farmers adopting portfolios with numerous advisory services.

description: We study the transport of vortices excited by an ac current in an Al film with an array of nanoengineered asymmetric antidots. The vortex response to the ac current is investigated by detailed measurements of the voltage output as a function of ac current amplitude, magnetic field and temperature. The measurements revealed pronounced voltage rectification effects which are mainly characterized by the two critical depinning forces of the asymmetric potential. The shape of the net dc voltage as a function of the excitation amplitude indicates that our vortex ratchet behaves in a way very different from standard overdamped models. Rather, as demonstrated by the observed output signal, the repinning force, necessary to stop vortex motion, is considerably smaller than the depinning force, resembling the behavior of the so-called inertia ratchets. Calculations based on an underdamped ratchet model provide a very good fit to the experimental data.

description: The standard Large Deviation Theory (LDT) is mathematically illustrated by the Boltzmann-Gibbs factor which describes the thermal equilibrium of short-range-interacting many-body Hamiltonian systems, the velocity distribution of which is Maxwellian. It is generically applicable to systems satisfying the Central Limit Theorem (CLT). When we focus instead on stationary states of typical complex systems (e.g., classical long-range-interacting many-body Hamiltonian systems, such as self-gravitating ones), the CLT, and possibly also the LDT, need to be generalised. Specifically, when the $N\to\infty$ attractor ($N$ being the number of degrees of freedom) in the space of distributions is a $Q$-Gaussian (a nonadditive $q$-entropy-based generalisation of the standard Gaussian case, which is recovered for $Q=1$) related to a $Q$-generalised CLT, we expect the LDT probability distribution to asymptotically approach a power law. Consistently with available strong numerical indications for probabilistic models, this behaviour possibly is that associated to a $q$-exponential (defined as $e_q^x\equiv\left[1+(1-q)x\right]^{1/(1-q)}$, which is the generalisation of the standard exponential form, straightforwardly recovered for $q=1$); $q$ and $Q$ are expected to be simply connected, including the particular case $q=Q=1$. The argument of such $q$-exponential would be expected to be proportional to $N$, analogously to the thermodynamical entropy of many-body Hamiltonian systems. We provide here numerical evidence supporting the asymptotic power-law by analysing the standard map, the coherent noise model for biological extinctions and earthquakes, the Ehrenfest dog-flea model, and the random-walk avalanches.

description: Traders' perceptions drive their market behavior, and can influence the dynamics of liquidity. This study surveyed 420 traders on their perceptions of the price path during an order imbalance to better understand the dynamics of liquidity. While most liquidity models assume a linear price path, only 12% of traders perceive such a path. This raises questions on the validity of such models. There is considerable heterogeneity in the perceptions of the price path. While trader characteristics are often used to classify traders, trader characteristics do not explain the heterogeneity in perceptions. On the other hand, traders of a specific contract are associated with particular perceptions of the price path. This indicates that market microstructure may be the primary driver of traders' perceptions of the price path.

description: Basis behavior is generally considered to be the major determinant of hedging success or failure. In the course of our work as contract designers for Chicago Mercantile Exchange Inc., we have come to the conclusion that there are many misconceptions and incorrect statements made about "the basis" among practitioners and academics alike. Our work suggests that basis values, how they are measured, what they represent and how they are interpreted may differ widely from one commodity contract to another due to differences in the specifications of the underlying futures market, as well as differences in the structure of the underlying cash market.
