description: Purpose: The purpose of this study was to examine the use of structural priming combined with a focused recasting procedure to elicit subject- and object-focused, center-embedded relative clauses from students with developmental language disorders (DLDs) and typically developing (TD) students.Method: A total of 26 children (13 DLD, 13 TD), ranging in age from 6;10 to 10;11 (years;months), participated in this study. All children completed a priming and recasting task that targeted subject- and object-focused relatives. The stimuli were presented in two blocks, which each contained 40 trials for each sentence type.Results: Children with DLD and their TD peers were significantly more accurate producing subject-focused than object-focused relatives. An analysis of rate of learning indicated that significantly more trials were required for subjects in the DLD group to demonstrate consistent performance on both subject- and object-focused relatives.Conclusions: The study supports the feasibility of combining an implicit priming task with an explicit recasting task for teaching subject-focused relative clauses to children with DLD. However, it is likely that additional instruction and/or more trials will be necessary for children with DLD to attain consistent performance levels.

description: Finite fermion systems are known to exhibit shell structure in the weakly-interacting regime, as well known from atoms, nuclei, metallic clusters or even quantum dots in two dimensions. All these systems have in common that the particle interactions between electrons or nucleons are spatially isotropic. Dipolar quantum systems as they have been realized with ultra-cold gases, however, are governed by an intrinsic anisotropy of the two-body interaction that depends on the orientation of the dipoles relative to each other. Here we investigate how this interaction anisotropy modifies the shell structure in a weakly interacting two-dimensional anisotropic harmonic trap. Going beyond Hartree-Fock by applying the so-called "importance-truncated" configuration interaction (CI) method as well as quadratic CI with single- and double-substitutions, we show how the magnetostriction in the system may be counteracted upon by a deformation of the isotropic confinement, restoring the symmetry.
Abiding in liminal space(s) : inscribing mindful living/dying with(in) end-of-life care

description: Mind-body approaches such as mindfulness meditation are increasingly incorporated into health care. Despite a growing interest in mindfulness, its Buddhist philosophical underpinnings remain unexplored in nursing. Without an awareness o f the nondualistic assumptions embedded in mindfulness and Buddhism, interpretations of this Eastern practice are limited. This inquiry engages Buddhist philosophical thought and the experiences of meditation practitioners. The purpose of this study was to explore mindfulness by those who regularly practiced mindfulness meditation and were caregivers in a Zen hospice or living with a life threatening illness. Approximately ten weeks of residency in a Zen monastery, and participation in day-to-day volunteer caregiving in the Zen hospice were undertaken. Indepth unstructured conversations were conducted; mindful, open-ended reflexivity (Varela, Thompson, & Rosch, 1991) and koan construction were used in ongoing analyses and interpretation. Theoretical explorations in this inquiry constitute and reflect knowledge(s) about that which is unknowable, indistinct, and ambiguous. The inquiry addresses how we may point to 'that' which is beyond words with attention given to language and what happens with/in language as we write and are written through texts. Unconventional forms and writing are used to question conventional privileging of representational binaries that value words over silence, life over death, clarity over paradox, and knowing over unknowing. Death, re-interpreted in the Buddhist sense of the participants, is constructed as momentary experience occurring each mind-moment. Life is not necessarily privileged over death, but rather is seen as a doubling o f living/dying intertwining within momentary awareness. A re-configuring of living/dying is suggested that differs from Western perspectives where 'living' holds hegemony over 'dying'. Death is situated in the midst o/:—liminal space(s) of being/not being and ubiquitous change while mindfulness meditation is seen as a parallel process providing an embodied realization of this transience. These perspectives may help nurses and health care professionals go beyond dualistic views and provide guidance for abiding in the midst of suffering that may be beyond words. Further inquiry into non-conceptual awareness and its relationship with health and wellness is needed.

description: Several past studies used time series data to estimate price elasticities of demand for fertilizer or nutrient use on all crops in the United States or by region. In this study, demand functions for nitrogen, phosphorous and potassium applied per acre of corn, wheat and soybeans in the United States were estimated, using a combination of autoregressive least squares and seemingly unrelated regression techniques. The results suggest that the demands for nitrogen, phosphorous and potassium applied to corn are price elastic, while similar responses for wheat and soybeans are price inelastic. Nitrogen and phosphorous applied per acre of corn were found to be positively related to government sponsored acreage diversion. The estimated elasticities could provide policymakers with insight for developing fertilizer and crop policies.

description: The notion of a coherent unit action on algebraic operads was first introduced by Loday for binary quadratic nonsymmetric operads and generalized by Holtkamp, to ensure that the free objects of the operads carry a Hopf algebra structure. There was also a classification of such operads in the binary quadratic nonsymmetric case. We generalize the notion of coherent unit action to braided operads and show that free objects of braided operads with such an action carries a braided Hopf algebra structure. Under the conditions of binary, quadratic and nonsymmetric, we give a characterization and classification of the braided operads that allow a coherent unit action and thus carry a braided Hopf algebra structure on their free objects.

description: Nonlinear realizations of spacetime groups are presented as a versatile mathematical tool providing a common foundation for quite different formulations of gauge theories of gravity. We apply nonlinear realizations in particular to both the Poincaré and the affine group in order to develop Poincaré gauge theory (PGT) and metric-affine gravity (MAG) respectively. Regarding PGT, two alternative nonlinear treatments of the Poincaré group are developed, one of them being suitable to deal with the Lagrangian and the other one with the Hamiltonian version of the same gauge theory. We argue that our Hamiltonian approach to PGT is closely related to Ashtekar's approach to gravity. On the other hand, a brief survey on MAG clarifies the role played by the metric--affine metric tensor as a Goldsone field. All gravitational quantities in fact --the metric as much as the coframes and connections-- are shown to acquire a simple gauge--theoretical interpretation in the nonlinear framework.

description: This study estimates some of the economic impacts of a program that would allow farmers to save a part of their annual surface irrigation water allocation. The objective would be to save water in full allocation years to be used in water short years. The study area consisted of the El Paso County Water Improvement District. Results indicate that optimal temporal water use would increase district net farm revenue by three percent or less above actual water use. For the study area vegetables were the most profitable crop while laser leveling was not economically feasible.

description: We present near-infrared spectroscopy and narrow-band imaging at the wavelength of redshifted H-alpha for a sample of 30 high-redshift, far-infrared luminous galaxies. This sample is selected from surveys in the sub-millimeter, millimeter and radio wavebands and has complete redshift coverage with a median redshift of z~2.4. Removing obvious AGN, we find that the predicted H-alpha star formation rates in this diverse population are suppressed (by ~10x) compared to those derived from their far-infrared luminosities. We estimate that AGN are present in at least 40% of the galaxies in our sample. To further investigate this, we construct a composite rest-frame spectrum for both the entire sample and for those galaxies which individually show no signs of nuclear activity. We find [NII]/H-alpha ratios for both composite spectra which suggest that the energy output of the galaxies is star-formation- rather than AGN-dominated. The median H-alpha line width for our sample (removing obvious AGN) is 400+/-70km/s (FWHM), and the typical spatial extent of the H-alpha emission in our narrow-band observations is < 4-8kpc, which indicates a dynamical mass of 1-2 x 10^11 Mo. This estimate is larger than recent estimates of the dynamical masses of UV-selected galaxies at similar redshifts derived in an identical manner. We also compared our H-alpha and far-infrared luminosities with deep Chandra observations of a subset of our survey fields and use these data to further assess their AGN content. We conclude that these high-redshift, far-infrared luminous galaxies represent a population of massive, metal-rich, merging systems with high instantaneous star formation rates, strong dust obscuration and actively-fueled AGN which are likely to be the progenitors of massive local elliptical galaxies.

description: Films of titanate nanosheets (approx. 1.8-nm layer thickness and 200-nm size) having a lamellar structure can form electrolytefilled semi-permeable channels containing tetrabutylammonium cations. By evaporation of a colloidal solution, persistent deposits are readily formed with approx. 10 micrometer thickness on a 6-micrometer-thick poly(ethylene-terephthalate) (PET) substrate with a 20 micrometer diameter microhole. When immersed in aqueous solution, the titanate nanosheets exhibit a p.z.c. of -37 mV, consistent with the formation of a cation conducting (semi-permeable) deposit. With a sufficiently low ionic strength in the aqueous electrolyte, ionic current rectification is observed (cationic diode behaviour). Currents can be dissected into (i) electrolyte cation transport, (ii) electrolyte anion transport and (iii) water heterolysis causing additional proton transport. For all types of electrolyte cations, a water heterolysis mechanism is observed. For Ca2+ and Mg2+ ions, water heterolysis causes ion current blocking, presumably due to localised hydroxide-induced precipitation processes. Aqueous NBu4+ is shown to invert the diode effect (from cationic to anionic diode). Potential for applications in desalination and/or ion sensing are discussed
The $ν_{R}$-philic scalar: its loop-induced interactions and Yukawa forces in LIGO observations

description: Right-handed neutrinos ($ν_{R}$) are often considered as a portal to new hidden physics. It is tempting to consider a gauge singlet scalar $(ϕ)$ that exclusively couples to $ν_{R}$ via a $ν_{R}ν_{R}ϕ$ term. Such a $ν_{R}$-philic scalar does not interact with charged fermions at tree level but loop-induced effective interactions are inevitable, which are systematically investigated in this work. The magnitude of the loop-induced couplings coincidentally meets the current sensitivity of fifth-force searches. In particular, the loop-induced coupling to muons could be tested in the recent LIGO observations of neutron star mergers as there might be a sizable Yukawa force in the binary system mediated by the $ν_{R}$-philic scalar.

The first part reviews two population genetic models of Lenski's long-term evolution experiment with Escherichia coli, where models aim at explaining the observed curve of the evolution of the mean fitness. The second part describes a model of a host-pathogen system where the population of pathogenes experiences balancing selection, migration, and mutation, as motivated by observations of the genetic diversity of HCMV (the human cytomegalovirus) across hosts.

description: Quantum Monte Carlo and density-matrix renormalization group methods are used to study the coupled spin-pseudospin Hamiltonian in one-dimension (1D) that models the charge-ordering instability of the anisotropic Hubbard ladder at quarter filling. We calculate the temperature dependence of the uniform spin susceptibility and specific heat as well as the spin and charge excitation spectra of the system. We thereby show that there is a parameter and temperature region where the spin degrees of freedom are separated from the charge degrees of freedom and behave like a 1D antiferromagnetic Heisenberg model, and that, outside this parameter region and above a crossover temperature, the spin excitations are largely affected by the charge fluctuations. We argue that observed anomalous spin dynamics in the disorder phase of a typical charge-ordered material $α'$-NaV$_2$O$_5$ may possibly be a consequence of this type of spin-charge coupling.

description: The first CCD UBV(RI) photometric study in the area of the doubtful open cluster NGC 2129 is presented. Photometry of a field offset 15 arcmin northward is also provided, to probe the Galactic disk population toward the cluster. Using star counts, proper motions from the UCAC2 catalog, colour-magnitude and colour-colour diagrams we demonstrate that NGC 2129 is a young open cluster. The cluster radius is 2.5 arcmin, and across this region we find evidence of significant differential reddening, although the reddening law seems to be normal toward its direction. Updated estimates of the cluster fundamental parameters are provided. The mean reddening is found to be E(B-V)=0.80$\pm$0.08 and the distance modulus is $(m-M)_o$= 11.70$\pm0.30$. Hence, NGC 2129 is located at 2.2$\pm$0.2 kpc from the Sun inside the Local spiral arm. The age derived from 37 photometrically selected members is estimated to be approximately 10 million years. These stars are used to provide new estimates of the cluster absolute proper motion components.

description: We investigate the electronic, thermal, and optical characteristics of graphene like SiC$_x$ structure using model calculations based on density functional theory. The change in the energy bandgap can be tuned by the Si atomic configuration, rather than the dopants ratio. The effects of the concentration of the Si atoms and the shape of supercell are kept constant, and only the interaction effects of two Si atoms are studied by varying their positions. If the Si atoms are at the same sublattice positions, a maximum bandgap is obtained leading to an increased Seebeck coefficient and figure of merit. A deviation in the Wiedemann-Franz ratio is also found, and a maximum value of the Lorenz number is thus discovered. Furthermore, a significant red shift of the first peak of the imaginary part of the dielectric function towards the visible range of the electromagnetic radiation is observed. On the other hand, if the Si atoms are located at different sublattice positions, a small bandgap is seen because the symmetry of sublattice remains almost unchanged. Consequently, the Seebeck coefficient and the dielectric function are only slightly changed compared to pristine graphene. In addition, the electron energy loss function is suppressed in Si-doped graphene. These unique variations of the thermal and the optical properties of Si-doped graphene are of importance to understand experiments relevant to optoelectronic applications.

description: We report the discovery of a partial Einstein ring of radius 1.48arcsec produced by a massive (and seemingly isolated) elliptical galaxy. The spectroscopic follow-up at the VLT reveals a 2L* galaxy at z=0.986, which is lensing a post-starburst galaxy at z=3.773. This unique configuration yields a very precise measure of the mass of the lens within the Einstein radius, (8.3e11 +- 0.4)/h70 Msolar. The fundamental plane relation indicates an evolution rate of d [log (M/L)B] / dz = -0.57+-0.04, similar to other massive ellipticals at this redshift. The source galaxy shows strong interstellar absorption lines indicative of large gas-phase metallicities, with fading stellar populations after a burst. Higher resolution spectra and imaging will allow the detailed study of an unbiased representative of the galaxy population when the universe was just 12% of its current age.

description: In this paper we examine the virtual teamwork processes by focusing on the perceptions of undergraduate students when they transition, take action and build interpersonal relationships during an intensive multi-university learning project carried out at the time of COVID-19 pandemic. The participants (n=20) were Japanese undergraduate students from three universities enrolled in a synchronous online course in international organizations. The study employed inductive content analysis of students’ e-Portfolios completed during the course. It builds on the three-tier model of team processes (Marks, Mathieu & Zaccaro, 2001) as its theoretical framework. The findings are in line with previous research suggesting that virtual teams are multitasking entities that transition through multiple processes simultaneously and consequentially to achieve team goals. We conclude with implications for online teaching and collaborative learning.
Environmental risk and policy development in the British Columbia salmon farming industry
Creators: name: Pechlaner, Gabriela
Publisher: name: University of British Columbia
Year: 2009

description: Two competing perspectives of society's relationship to nature have risen to prominence, both in environmental social theory, and, in modified form, in current political discourse. Risk society theory proposes that society is shifting from one organized around the distribution of wealth to one organized around the distribution of risk, and that our current industrial society is unsustainable as currently structured. Ecological modernization theory proposes that as environmental issues increase in importance, ecological criteria will be incorporated into industrial production through a continuous process of adaptation and re-integration of nature. Ecological modernization, then, is offered as an alternative to a descent into a risk society, as described by Ulrich Beck. While there has been much debate between ecological modernization and risk society theorists as to industrial society's potential for ecological reform, few empirical studies exist that test the strength of ecological modernization theory in practice. Salmon farming in British Columbia has been subject to rigorous environmental debate in its short history. This thesis investigates the development of salmon farming policy in B. C. as a test case for the propositions of ecological modernization theory. Through an examination of theoretical literature, indicators of ecological modernization and risk society processes were derived. Salmon farming policy developments were analyzed for evidence of ecological reform and for the processes that accompanied these reforms. The results of the analysis revealed increasing evidence of certain ecological modernization processes, primarily ones associated with scientific and technological developments. Other indicators were consistently absent. Still others, such as stakeholder incorporation processes, were found to be in evidence in fact but not in spirit. The ecological modernization process described by theorists was not occurring in whole, but in part. However, economic interests persisted in dominating ecological ones. Counter interpretations found institutional and interest group factors, as well as changes in background conditions, to be highly influential on ecological reforms. The greatest weakness of ecological modernization as an explanatory theory was found to be its inability to incorporate issues of power and inequality into its framework. This, and ecological modernization theory's assumptions of consensus towards its goals, are the greatest impediments to its translation from a social theory into a political program.

description: The LIGO/Virgo collaboration have by now detected the mergers of ten black hole binaries via the emission of gravitational radiation. The hypothesis that these black holes have formed during the cosmic QCD epoch and make up all of the cosmic dark matter, has been rejected by many authors reasoning that, among other constraints, primordial black hole (PBH) dark matter would lead to orders of magnitude larger merger rates than observed. We revisit the calculation of the present PBH merger rate. Solar mass PBHs form clusters at fairly high redshifts, which evaporate at lower redshifts. We consider in detail the evolution of binary properties in such clusters due to three-body interactions between the two PBH binary members and a third by-passing PBH, for the first time, by full numerical integration. A Monte-Carlo analysis shows that formerly predicted merger rates are reduced by orders of magnitude due to such interactions. The natural prediction of PBH dark matter formed during the QCD epoch yields a pronounced peak around $1M_{\odot}$ with a small mass fraction of PBHs on a shoulder around $30M_{\odot}$, dictated by the well-determined equation of state during the QCD epoch. We employ this fact to make a tentative prediction of the merger rate of $\sim 30M_{\odot}$ PBH binaries, and find it very close to that determined by LIGO/Virgo. Furthermore we show that current LIGO/Virgo limits on the existence of $\sim M_{\odot}$ binaries do not exclude QCD PBHs to make up all of the cosmic dark matter. Neither do constraints on QCD PBHs from the stochastic gravitational background, pre-recombination accretion, or dwarf galaxies pose a problem. Microlensing constraints on QCD PBHs should be re-investigated. We caution, however, in this numerically challenging problem some possibly relevant effects could not be treated.

description: This study has identified several important factors affecting consumer negative perceptions about beef irradiation. The effects of these factors boil down to two main points: lack of trust in the adequacy and enforcement effectiveness of food safety regulations and consumer ignorance about the irradiation process. This implies dissemination of information about food irradiation and enhancement of consumer trust in the mechanism of food safety regulation can be effective instruments to increase consumer acceptance of beef irradiation.

Interacting viscous mixtures

description: Gravitational and hydrodynamical perturbations are analysed in a relativistic plasma containing a mixture of interacting fluids characterized by a non-negligible bulk viscosity coefficient. The energy-momentum transfer between the cosmological fluids, as well as the fluctuations of the bulk viscosity coefficients, are analyzed simultaneously with the aim of deriving a generalized set of evolution equations for the entropy and curvature fluctuations. For typical length scales larger than the Hubble radius, the fluctuations of the bulk viscosity coefficients and of the decay rate provide source terms for the evolution of both the curvature and the entropy fluctuations. According to the functional dependence of the bulk viscosity coefficient on the energy densities of the fluids composing the system, the mixing of entropy and curvature perturbations is scrutinized both analytically and numerically.

description: Egypt's derived feed demand for poultry and eggs and its dependency on world feed markets was econometrically projected to 2010. Results reveal a poultry industry as highly dependent on imports, where dependency rate will approach 100 percent for soybeans and 48 percent for yellow corn in 2010.

description: Menger's basis property is a generalization of $σ$-compactness and admits an elegant combinatorial interpretation. We introduce a general combinatorial method to construct non $σ$-compact sets of reals with Menger's property. Special instances of these constructions give known counterexamples to conjectures of Menger and Hurewicz. We obtain the first explicit solution to the Hurewicz 1927 problem, that was previously solved by Chaber and Pol on a dichotomic basis. The constructed sets generate nontrivial subfields of the real line with strong combinatorial properties, and most of our results can be stated in a Ramsey-theoretic manner. Since we believe that this paper is of interest to a diverse mathematical audience, we have made a special effort to make it self-contained and accessible.
Personality, stress and coping in step-families
Creators: name: Lee-Baggley, Dayna
Publisher: name: University of British Columbia

description: The current study examined the role of dimensions of personality derived from the five-factor model (Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness) in coping with interpersonal family stressors (marital conflict and child misbehavior). The study used a daily process methodology and a hierarchical linear modeling analysis strategy to examine the independent and interactive effects of personality and situation on coping strategy use. Seventy-seven couples living in a stepfamily context reported interpersonal family stressors and coping twice daily for a week. Nine subscales of coping were examined based on the three main functions of coping: problem-, emotion- and relationship focused. Both the situational context and all of the five dimensions of personality examined were significantly and independently related to coping strategy use. Moreover, there were significant interactions of personality with context in predicting coping responses to stress. The present study highlights the importance of considering personality in context when examining coping behaviours.

description: We compare high-resolution optical and radio imaging of 12 luminous submm galaxies at z=2.2+/-0.2 observed with HST and the MERLIN and VLA at comparable spatial resolution, 0.3" (2kpc). The radio emission traces the likely far-infrared morphology of these dusty, luminous galaxies. In ~30% of the sample the radio appears unresolved, suggesting that the emission is compact: either an obscured AGN or nuclear starburst. However, in the majority, ~70% (8/12), the radio emission is resolved by MERLIN/VLA on scales of ~1" (10 kpc). For these galaxies the radio morphologies are broadly similar to their restframe UV emission seen by HST. We discuss the probable mechanisms for the extended emission and conclude that their luminous radio and submm emission arises from a large, spatially-extended starburst. The median SFRs are 1700Mo/yr occuring within a ~40kpc^2 region, giving a star formation density of 45Mo/yr/kpc^2. Such vigorous and extended starbursts appear to be uniquely associated with the submm population. A more detailed comparison of the distribution of UV and radio emission shows that the broad similarities on large scales are not carried through to smaller scales, where there is rarely a one-to-one correspondance. We interpret this as resulting from highly structured internal obscuration, suggesting that the vigorous activity is producing wind-blown channels through the obscuration in these galaxies. If correct this underlines the difficulty of using UV morphologies to understand structural properties of this population and also may explain the surprising frequency of Ly-alpha emission in their spectra.

description: A probit model for whether or not consumers would buy irradiated poultry products is estimated jointly with an OLS equation for the price premiums that consumers are willing to pay for irradiated chicken breast meat. The results suggest that educating consumers about irradiation would be beneficial to the food industry.

description: High-resolution optical imaging methods, such as confocal microscopy and full-field optical coherence tomography, capture flat optical sections of the sample. If the sample is curved, the optical field sections through several sample layers and the view of each layer is reduced. Here we present curved-field optical coherence tomography, capable of capturing optical sections of arbitrary curvature. We test the device on a challenging task of imaging the human cornea in vivo and achieve 10x larger viewing area comparing to the clinical state-of-the-art. This enables more precise cell and nerve counts, opening a path to improved diagnosis of corneal and general health conditions (e.g. diabetes). The method is non-contact, compact and works in a single-shot, making it readily available for use in optical research and clinical practice.

description: Este trabajo pretende presentar el modo en que uno de los intelectuales
puertorriqueños del siglo XIX, Ramón E. Betances, construye una ficción
fundacional y (re)piensa las relaciones político-sociales que ya se habían construido del país. La novela Los dos indios: Episodio de la conquista de Borinquen y el poema que le da continuidad a la obra “A Borinquen” serán estudiados bajo bases teóricas anticoloniales y el concepto de Doris Sommer llamado “ficciones fundacionales”. A partir de la relación dialéctica del “amo y el esclavo” teorizada por Georg Hegel se puede percibir cómo en estas obras Betances construye un imaginario nacional de la isla de Borinquen cuya riqueza se nutre de la cultura nativa anterior a la llegada de los colonizadores españoles. Además, establece que la existencia y esencia de Borinquen solo
podrá persistir cuando los españoles colonizadores salgan de la Isla. El análisis de ambas obras permitirá ver cómo para Ramón E. Betances el alcanzar la libertad de su país solo es posible de la mano de los oprimidos.
Many-particle hydrodynamic interactions in parallel-wall geometry: Cartesian-representation method

description: This paper describes the results of our theoretical and numerical studies of hydrodynamic interactions in a suspension of spherical particles confined between two parallel planar walls, under creeping-flow conditions. We propose a novel algorithm for accurate evaluation of the many-particle friction matrix in this system--no such algorithm has been available so far. Our approach involves expanding the fluid velocity field into spherical and Cartesian fundamental sets of Stokes flows. The interaction of the fluid with the particles is described using the spherical basis fields; the flow scattered with the walls is expressed in terms of the Cartesian fundamental solutions. At the core of our method are transformation relations between the spherical and Cartesian basis sets. These transformations allow us to describe the flow field in a system that involves both the walls and particles. We used our accurate numerical results to test the single-wall superposition approximation for the hydrodynamic friction matrix. The approximation yields fair results for quantities dominated by single particle contributions, but it fails to describe collective phenomena, such as a large transverse resistance coefficient for linear arrays of spheres.

description: In this paper, we introduce Berry curvature, topological Chern number and topological chiral edge mode, that emerge from a hybridization between magnon and electromagnetic wave in a ferromagnet insulator. By focusing on the energy conservation, we first reformulate the Landau-Lifshitz-Maxwell equation into a Hermitian eigenvalue equation. From the eigenvalue equation, we define the Berry curvature of the magnon-photon coupled waves. We show that the Berry curvature thus introduced shows a prominent peak around a hybridization point between magnon mode and photon mode, and a massive hybrid mode takes a non-zero Chern number ($\pm 1$) due to the magnon-photon coupling. In accordance with the non-zero Chern number, the topological edge modes emerge inside the hybridization gap at a domain wall between two ferromagnetic insulators with opposite magnetizations.

description: After over eight years of trading, the Chicago Mercantile Exchange butter futures contract remains thinly traded, possibly impeding price discovery. Pricing efficiency was assessed using cointegration techniques and error correction models. Results suggest that market efficiency could not be rejected up to a two-month forecast horizon. Illiquid markets reduce hedging performance, which in turn discourage liquidity growth.
