description: Selenium is an element found in relatively high concentrations in crops and livestock raised on high-selenium soils located in North and South Dakota. Evidence suggests that a high-selenium diet such as would be obtained from consuming these products can reduce the risk of certain cancers. The region's livestock and grain producers are exploring potential high-selenium product marketing opportunities. A choice experiment was conducted to identify preferred attributes for a high-selenium beef product and the characteristics of potential market segments. In a national survey, participants chose between different levels of health claim approval and research, prices, and selenium origin. A multinomial logit regression model was estimated. Labeling reflecting scientific support linking selenium and reduced cancer risk, and natural-source selenium was ineffective. Marketing opportunities identified are consistent with existing functional food market segments and include consumers with higher income and education, 45 to 55 years of age, and with children.
Improving the brightness and bleachability of douglas-fir mechanical pulps using white-rot fungi and laccase enzymes
Creators: name: Chandra, Richard P.
Publisher: name: University of British Columbia
Year: 2009

description: Douglas-fir is a common west coast tree species, possessing long and strong fibers, however, the low brightness and poor bleachability of mechanical pulps from this tree have thus far limited its use to low yield Kraft pulps and lumber. The heartwood of Douglas-fir has been shown to contain a high amount of polyphenolic compounds such as dihydroquercetin and/or polymerized forms of these compounds. These compounds have been shown to undergo autooxidation, condensation, polymerization and metal chelation during either the aging of the tree or mechanical pulping of the wood, resulting in the formation of dark coloured complexes in the pulp. Although chemical treatments to improve the bleaching response of Douglas-fir mechanical pulps have been unsuccessful, biological treatments have yet to be applied. Douglas-fir mechanical pulps were treated either with wood degrading fungi or laccase enzymes to try to improve the brightness of mechanical pulps originating from the polyphenolic chromophoric compounds present in the heartwood portion of this tree. Results of fungal screening showed that the white-rot fungus Phanerochaete chrysosporium increased brightness of Douglas-fir refiner mechanical pulps by 1.5 pts ISO. Unfortunately P.chrysosporium treatment was unable to increase the brightness o f pure Douglas-fir heartwood thermomechanical pulps. Although, earlier work had shown that the production of laccase was induced in the fungus Trametes versicolor in the presence of dihydroquercetin, Trametes versicolor treatment of heartwood mechanical pulps combined with chemical extraction did not result in any brightness increases greater than what could be obtained using chemical extraction alone. Laccase treatments without enzyme mediators decreased the unbleached brightness of Douglas-fir heartwood mechanical pulps by 4-5 pts ISO, however, after bleaching, the pulp brightness surpassed the control pulps by 2-3 pts ISO. With the addition of oxygen, an enzyme mediator, or increasing the temperature, laccase treatments decreased both the unbleached and the bleached brightness values compared to the controls. However, the addition of oxygen alone was able to increase the brightness of all pulps by 1-2 pts ISO. Preliminary absorption measurements of laccase treated handsheets indicated that the production of coloured quinone type structures in the mechanical pulps may be associated with the positive effects of laccase treatments.
Aggregates of rod-coil diblock copolymers adsorbed at a surface

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The behaviour of rod-coil diblock copolymers close to a surface is discussed by using extended scaling methods. The copolymers are immersed in selective solvent such that the rods are likely to aggregate to gain energy. The rods are assumed to align only parallel to each other, such that they gain a maximum energy by forming liquid crystalline structures. If an aggregate of these copolymers adsorbs with the rods parallel to the surface the rods shift with respect to each other to allow for the chains to gain entropy. It is shown that this shift decays with increasing distance from the surface. The profile of this decay away from the surface is calculated by minimisation of the total free energy of the system. The stability of such an adsorbed aggregate and other possible configurations are discussed as well.

description: Based on infinite one-dimensional single-electron periodic models of trans-polyacetylene, we show analytically that the overall permutation symmetry of nonlinear optical susceptibilities is, albeit preserved in the molecular systems with only bound states, no longer generally held for the periodic systems. The overall permutation symmetry breakdown provides a fairly natural explanation to the widely observed large deviations of Kleinman symmetry for periodic systems in off-resonant regions. Physical conditions to experimentally test the overall permutation symmetry break are discussed.

description: We study populations of High-Mass X-ray Binaries in the Galaxy using data of the INTEGRAL observatory in a hard X-ray energy band. More than two hundreds of sources were detected with INTEGRAL near the galactic plane (|b|<5 deg), most of them have a galactic origin and belong to high (HMXB) and low mass (LMXB) X-ray binaries. We investigated properties and spectra of a large sample of HMXBs and concluded that most of them are belong to X-ray pulsars. We also build the distribution of HMXBs for the whole Galaxy and showed that its peaks are practically coincident with spiral arm tangents. The obtained results are discussed in terms of some model estimations of the density of different components of the Galaxy.

description: This paper reviews the development status of GRAPE (the Gamma-Ray Polarimeter Experiment), a hard X-ray Compton Polarimeter. The purpose of GRAPE is to measure the polarization of hard X-rays in the 50-300 keV energy range. We are particularly interested in X-rays that are emitted from solar flares and gamma-ray bursts (GRBs), although GRAPE could also be employed in the study of other astrophysical sources. Accurately measuring the polarization of the emitted radiation will lead to a better understating of both emission mechanisms and source geometries. The GRAPE design consists of an array of plastic scintillators surrounding a central high-Z crystal scintillator. The azimuthal distribution of photon scatters from the plastic array into the central calorimeter provides a measure of the polarization fraction and polarization angle of the incident radiation. The design of the detector provides sensitivity over a large field-of-view (>pi steradian). The design facilitates the fabrication of large area arrays with minimal deadspace. This paper presents the latest design concept and the most recent results from laboratory tests of a GRAPE science model.

description: Mushrooms have been grown commercially on many different substrates for years, usually agricultural by-products such as straw or stover. Increased popularity for specialty mushrooms with consumers has led to increased production and great demand for economic substrates. Oyster mushrooms are easier to grow relative to other types of mushrooms and their production has increased dramatically in recent years. This study examines the economic feasibility of using soybean hulls as a primary substrate for oyster mushrooms, replacing traditional wheat straw. The study uses a cost-benefit analysis to determine an optimal substrate based on yield and the number of crops harvested per year. The study shows that soybean hulls, combined with corn gluten or soybean meal increases yield 4.5 times, which more than offsets for higher costs for soybean hulls. The use of soybean substrate also allows a producer to raise about four more crops per year, which in turn uses fixed resources more efficiently and increases profitability.

description: The efficient simulation of models defined in terms of stochastic differential equations (SDEs) depends critically on an efficient integration scheme. In this article, we investigate under which conditions the integration schemes for general SDEs can be derived using the Trotter expansion. It follows that, in the stochastic case, some care is required in splitting the stochastic generator. We test the Trotter integrators on an energy-conserving Brownian model and derive a new numerical scheme for dissipative particle dynamics. We find that the stochastic Trotter scheme provides a mathematically correct and easy-to-use method which should find wide applicability.

description: The optical trapping and manipulation of small particles is an important tool for probing fluid properties at the microscale. In particular, microrheology exploits the manipulation and rotation of micron-scale particles to probe local viscosity, especially where these properties may be perturbed as a function of their local environment, for example in the vicinity of cells. To this end, birefringent particles are useful as they can be readily controlled using optically induced forces and torques, and thereby used to probe their local environment. However the magnitude of optical torques that can be induced in birefringent particles is small, and a function of the particle diameter, meaning that rotational flow cannot readily be probed on length scales much small than the micron level. Here we show modelling that demonstrates that eccentric spherical core-shell nanoparticles can be used to generate considerable optical torques. The eccentricity is a result of the displacement of the centre of the core from the shell. Our results show that, for particles ranging from 90~nm to 180~nm in diameter, we may achieve rotation rates exceeding 800~Hz. This fills a missing size gap in the rotation of microparticles with optical forces. The diameter of particle we may rotate is almost an order of magnitude smaller than the smallest birefringent particles that have been successfully rotated to date. The rotation of eccentric core-shell nanoparticles therefore makes an important contribution to biophotonics and creates new opportunities for rheology in nanoscale environments.

description: The purpose of this study was to estimate the economic contribution of crude oil and natural gas exploration, extraction, transportation, and processing in North Dakota in 2005. Primary data for the study came from three separate surveys of firms involved with various aspects of the petroleum industry. Exploration, the process of finding mineral resources, was estimated to have direct impacts (in-state expenditures) of $445.1 million. Extraction, the process of developing and recovering mineral resources, had direct impacts of $909.6 million. The processing sector of the industry, which included pipeline transportation of crude oil and natural gas, had $132 million in direct impacts. The North Dakota Input-Output Model was used to estimate the secondary economic impacts (multiplier effects). The $1.4 billion in direct impacts were estimated to generate $2.4 billion in secondary impacts. The gross business volume for the entire industry in North Dakota in 2005 was estimated at $3.9 billion. Other economic measures for the industry were estimated, which included direct contributions to local and state government tax revenues of over $280 million, 5,267 full-time jobs, economy-wide personal income of $1.5 billion, statewide retail sales of over $900 million, indirect contribution of $55 million in state government general tax collections, and secondary employment of 20,650 full-time equivalent jobs. While only a snapshot in time, results from this study would suggest that recent upswings in energy prices, increased drilling activity, and growth in oil and gas production in North Dakota have made the petroleum industry the one of largest single industries in the state.

description: We derive the dominant part of the O(α_s^2) correction to the photon energy spectrum in the inclusive decay B-> X_s+gamma. The detailed knowledge of the spectrum is important for relating the theoretical calculations of the B-> X_s + γdecay rate and the experimental measurements where a cut on the photon energy is applied. In addition, moments of the photon energy spectrum are used for the determination of the b-quark mass and other fundamental parameters of heavy quark physics. Our calculation reduces the theoretical uncertainty associated with uncalculated higher orders effects and shows that, for B-> X_s+γ, QCD radiative corrections to the photon energy spectrum are under theoretical control.

description: Nanocomposites have been widely applied in medical device fabrication and tissue-engineering applications. In this context, the release of metal ions as well as protein adsorption capacity are hypothesized to be two key processes directing nanocomposite-cell interactions. The objective of this study is to understand the polymer-matrix effects on ion release kinetics and their relations with protein adsorption. Laser ablation in macromolecule solutions was employed for synthesizing Au and Fe nanoparticle-loaded nanocomposites based on thermoplastic polyurethane (TPU) and alginate. Confocal microscopy revealed a three-dimensional homogeneous dispersion of laser-generated nanoparticles in the polymer. The physicochemical properties revealed a pronounced dependence upon embedding of Fe and Au nanoparticles in both polymer matrices. Interestingly, the total Fe ion concentration released from alginate gels under static conditions decreased with increasing mass loadings, a phenomenon only found in the Fe-alginate system and not in the Cu/Zn-alginate and Fe-TPU control system (where the effects were proportioonal to the nanoparticle load). A detailed mechanistic examination of iron the ion release process revealed that it is probably not the redox potential of metals and diffusion of metal ions alone, but also the solubility of nano-metal oxides and affinity of metal ions for alginate that lead to the special release behaviors of iron ions from alginate gels. The amount of adsorbed bovine serum albumin (BSA) and collagen I on the surface of both the alginate and TPU composites was significantly increased in contrast to the unloaded control polymers and could be correlated with the concentration of released Fe ions and the porosity of composites, but was independent of the global surface charge. Interestingly, these effects were already highly pronounced at minute loadings with Fe nanoparticles down to 200 ppm. Moreover, the laser-generated Fe or Au nanoparticle-loaded alginate composites were shown to be a suitable bioink for 3D printing. These findings are potentially relevant for ion-sensitive bio-responses in cell differentiation, endothelisation, vascularisation, or wound healing.

description: This paper examines the effects of the U.S.-Korea free trade agreement (KORUS FTA) on various sectors of the economy in the two countries using a general equilibrium model. Additional analysis focuses on the agricultural sector. Our analysis indicates that the increase in U.S.-Korea bilateral trade volume in recent years has been through intra-industry trade of high-technology products. Under the KORUS FTA, the bilateral trade volume would increase for virtually all the sectors, and GDP and social welfare would improve for both countries. However, producers of textile products in the United States and producers of agricultural and food products in South Korea would suffer from the FTA. This agreement could benefit U.S. agriculture, but the benefits could be greater in the long run as duties on beef and other meat products are eliminated.

description: The net effect of food policies, viewed in terms of reduction of foodborne illness, death and food related diseases from obesity, may sometimes be much smaller than the predicted effect because of failure to account for offsetting behavior (OB). Theoretical and empirical models are developed and tested to determine the presence of dominant or partial OB in food safety policies. Results reveal that information that affects outrage and other determinants of risk perception will cause consumers to relax their vigilance in response to the food safety policy. This behavioral anomaly indicates a serious deviation from rational choice and may help explain the growing gap between the decrease in pathogen levels recorded after hazard analysis of critical control points implementation in meat processing plants and the number of outbreaks of food poisoning cases caused by foodborne pathogens.

description: This report summarizes the 2007 results of the North Dakota Land Valuation Model. The model is used annually to estimate average land values by county, based on the value of production from cropland and non-cropland. The county land values developed from this procedure form the basis for the 2007 valuation of agricultural land for real estate tax assessment. The average "all land value" from this analysis is multiplied by the total acres of agricultural land on the county abstract to determine each county's total agricultural land value for taxation purposes. The State Board of Equalization compares this value with the total value assessed to agricultural property in each county. Each county is required by state statute to assess a total value of agricultural property within 5 percent of this value. The average value per acre of all agricultural land in North Dakota increased by 0.79 percent, from 2006 to 2007, based on the value of production. Cropland value increased by 0.36 percent and non-cropland value increased by 5.17 percent. The formula capitalization rate was below the minimum set by the State Legislature, therefore the minimum rate of 8.3 percent was used. Changes in market value are included for comparison. Market value data are from the annual County Rents and Values survey conducted by North Dakota Agricultural Statistics Service.

We report on the detection of three cyclotron resonance features at 27, 51, and 74 keV in the phase-averaged data, corresponding to a polar magnetic field of 2.7 x 10^12 G. After 4U0115+63, this makes V0332+53 the second accreting neutron star in which more than two cyclotron lines have been detected; this has now also been confirmed by INTEGRAL. Pulse-phase spectroscopy reveals remarkably little variability of the cyclotron line through the 4.4 s X-ray pulse.

description: The neutrinoproduction of charged $ρ$ mesons on nuclei and nucleons is investigated for the first time at moderate energies ($ \approx$ 10 GeV), using the date obtained with SKAT bubble chamber. No strong nuclear effects are observed in $ρ^+$ and $ρ^-$ production. The fractions of charged and neutral pions originating from $ρ$ decays are obtained and compared with higher energy data. From analysis of the obtained and available data on $ρ^+$ and $K^{*+}$(892) neutrinoproduction, the strangeness suppression factor in the quark string fragmentation is extracted: $λ_s = 0.18\pm0.03$. Estimations are obtained for cross sections of quasiexclusive single $ρ^+$ and coherent $ρ^+$ neutrinoproduction on nuclei. The estimated coherent cross section $σ_{ρ^+}^{coh}$ = (0.29$\pm0.16)\cdot 10^{-38}$ cm$^2$ is compatible with theoretical predictions.

description: In this work we have obtained a charged black hole solution in the presence of perfect fluid dark matter (PFDM) and discuss its energy conditions. The metric corresponding to the rotating avatar of this black hole solution is obtained by incorporating the Newman-Janis algorithm. We then compute two types of circular geodesics, namely, the null geodesics and time-like geodesics for this rotating spacetime geometry. For the case of time-like geodesics, we consider both neutral as well as charged massive particles. The effective potentials of the corresponding circular geodesics has also been studied. We then present our results by graphically representing the collective effects of the black hole parameters, namely, the charge of the black hole ($Q$), spin parameter ($a$) and the PFDM parameter ($α$) on the energy ($E$), angular momentum ($L$) and effective potential ($V_{eff}$) of the concerned particle. Finally, we discuss the Penrose process in order to study the negative energy particles having possible existence within the ergosphere, and which in turn leads to the energy gain of the emitted particle.

description: This dissertation examines generic trends and ideological innovations in contemporary women’s coming-of-age narratives in the United States. Through a comparative genre study, I illuminate and interpret a number of key revisions within the genre since the late-eighteenth and nineteenth-century classics, including a radical shift in the endings of many recent texts. I show that today’s female bildungsroman subject is ethnically, racially, and socioeconomically diverse, and that she is getting older. She has an overall broader sense of educational and professional opportunity, and more relaxed attitudes toward sexuality and marriage than protagonists in the past. These shifts have implications for today’s narrative endpoints, and as I demonstrate throughout this dissertation, many recent female bildungsromane have conclusions that are conspicuously open-ended and future-oriented, rather than ending in marriage, death, or disillusionment. Contra Franco Moretti’s 1987 claim that “A Bildung is truly such only if, at a certain point, it can be seen as concluded: only if youth passes into maturity, and comes there to a stop” (26), authors today often eschew traditional endpoints for their female protagonists, suggesting and often celebrating the opportunity for protagonists’ further development and personal exploration. This kind of flexible, “in process” narrative resolution reflects, I argue, a contemporary view of development as a continual experience, rather than a discrete stage that is confined to youth. Implicit in the view of development as an ongoing process is a sense of hopefulness. Though that hope may be tentative, it marks many of today’s texts, even those that feature traumatic conditions and hardship. In this dissertation, I show that the shift to flexible, open endings is borne out across a diverse group of texts from the past decade (2006-2016): Daniel Woodrell’s Winter’s Bone (2006), Jesmyn Ward’s Salvage the Bones (2011), Jeffrey Eugenides’s The Marriage Plot (2011), Chimamanda Ngozi Adichie’s Americanah (2013), Susan Choi’s My Education (2013), and Patricia Park’s Re Jane (2015). In each of my three chapters, I explore generic revisions by focusing on a classic bildungsroman trope— education, migration and mobility, and social class. Contemporary modifications to these tropes correspond to revisions in the ways that today’s female protagonists view themselves in the world. While these texts remain identifiable as bildungsromane and are connected to the generic tradition in key ways, this body of texts also reconceptualizes the sites, timelines, and goals for female development and identity formation today

description: Optical isolation enables nonreciprocal manipulations of light with broad applications in optical communications. Optical isolation by rotating structures has drawn considerable attention due to its magnetic-free nature and unprecedented performance. Conventional rotation-based optical isolation relies on the use of bulky cavities hindering applications in subwavelength photonics. Here, we propose a novel mechanism of optical isolation by integrating the unique dispersion of a hyperbolic metamaterial with the transverse spin-orbit interaction of evanescent waves. We show that rotation of a subwavelength hyperbolic nanoparticle breaks the time-reversal symmetry and yields two resonant chiral modes that selectively couple to the transverse spin of waveguide modes. Remarkably, the transverse spin-orbit interaction can give rise to unidirectional coupling and $>95\%$ isolation of infrared light at an experimentally feasible rotation speed. Our work fuses the two important fields of optical isolation and photonic spin-orbit interactions, leading to magnetic-free yet compact nonreciprocal devices for novel applications in optical communications, chiral quantum optics, and topological photonics.

description: We study analytically the emergence of spontaneous collective motion within large bidimensional groups of self-propelled particles with noisy local interactions, a schematic model for assemblies of biological organisms. As a central result, we derive from the individual dynamics the hydrodynamic equations for the density and velocity fields, thus giving a microscopic foundation to the phenomenological equations used in previous approaches. A homogeneous spontaneous motion emerges below a transition line in the noise-density plane. Yet, this state is shown to be unstable against spatial perturbations, suggesting that more complicated structures should eventually appear.

Intersectionality

description: This work investigates the structural motives for the reproduction of a traditional white and male narrative in Brazilian history textbooks. To understand the resistance to change, this study combines quantitative and qualitative methodologies, analyzing both the content of a popular high school history collection and looking at textbook’s contexts of production, evaluation and use in class. First, a content analysis with an intersectional approach applied to all three volumes of História, Sociedade e Cidadania reveals the extent to which the main protagonists in the narrative are white, male, and in positions of power—and to which women, especially indigenous, black and Asian women, are underrepresented. The second part of the project leaves the book to investigate the structures of production, evaluation and uses of textbooks in Brazil, drawing from official documents and semi-structured interviews with a school teacher, textbook editors and a federal evaluator. This work argues that, even though in the last decade the black and indigenous movements were guaranteed legal rights towards representation in the curricula, a combination of four factors—the market, the state, the existing systems of oppression and the ways books are used in class—contribute to the maintenance of a canonical version of history in Brazilian textbooks

description: The recent detection of linear polarization from GRB120206 has piqued the interest of the community in this relatively unexplored avenue of research. Here, we review the current status and prospects for GRB polarimetry at hard X-ray and soft gamma-ray energies. After reviewing the most recent results, we present a brief survey of current and planned experiments that are capable of making GRB polarization measurements in the energy range between 30 keV and 30 MeV.

Geometric phases and criticality in spin chain systems

description: A relation between geometric phases and criticality of spin chains is established. As a result, we show how geometric phases can be exploited as a tool to detect regions of criticality without having to undergo a quantum phase transition. We analytically evaluate the geometric phase that correspond to the ground and excited states of the anisotropic XY model in the presence of a transverse magnetic field when the direction of the anisotropy is adiabatically rotated. Ultra-cold atoms in optical lattices are presented as a possible physical realization.

description: QCD splittings are among the most fundamental theory concepts at the LHC. We show how they can be studied systematically with the help of invertible neural networks. These networks work with sub-jet information to extract fundamental parameters from jet samples. Our approach expands the LEP measurements of QCD Casimirs to a systematic test of QCD properties based on low-level jet observables. Starting with an toy example we study the effect of the full shower, hadronization, and detector effects in detail.

Compressors

description: Heat pumps that use dynamic compressors, are an attractive solution to theincreasing demand for highly efficient & low emission thermal requirementsof residential and industrial sectors. These systems are subjected tocompression system instabilities, which require special attention due totheir closed loop, multi-phase, real gas behaviour. The designers of suchsystem must know in advance when these instabilities start, how strong theywould be, and how they can be mitigated. Herein lies the necessity todevelop dynamic models which can predict different complex phenomenonfrom the perspective of the closed loop system.
Simultaneous Flavor Transformation of Neutrinos and Antineutrinos with Dominant Potentials from Neutrino-Neutrino Forward Scattering

description: In astrophysical environments with intense neutrino fluxes, neutrino-neutrino forward scattering contributes both diagonal and off-diagonal potentials to the flavor-basis Hamiltonian that governs neutrino flavor evolution. We examine a special case where adiabatic flavor evolution can produce an off-diagonal potential from neutrino-neutrino forward scattering that dominates over both the corresponding diagonal term and the potential from neutrino-matter forward scattering. In this case, we find a solution that, unlike the ordinary Mikeyhev-Smirnov-Wolfenstein scenario, has both neutrinos and antineutrinos maximally mixed in medium over appreciable ranges of neutrino and antineutrino energy. Employing the measured solar and atmospheric neutrino mass-squared differences, we identify the conditions on neutrino fluxes that are required for this solution to exist deep in the supernova environment, where it could affect the neutrino signal, heavy-element nucleosynthesis, and even the revival of the supernova shock. We speculate on how this solution might or might not be attained in realistic supernova evolution. Though this solution is ephemeral in time and/or space in supernovae, it may signal the onset of subsequent appreciable flavor mixing for both neutrinos and antineutrinos. A similar solution may also exist in an early universe with significant net neutrino-lepton numbers.

Psychophysiological indicators of empathy, social interaction, and attention in children with autism
Creators: name: Kostaras, Demetra
Publisher: name: University of British Columbia
Year: 2009

description: Individuals with autism do not seem to respond to social situations, especially situations that, in individuals of typical development, elicit an empathic response. This study was designed to determine if heart rate could provide a means of investigating whether the social disturbance in autism is associated with specific empathy processes, general social interaction processes, or with general attention processes. Ten young male children with autism and 10 young male children of typical development (chronological age between 3-6.5 years) served as participants. The children were exposed to three auditory tones (a cry, a laugh, and a tone), while their heart rate was measured. The experiment took place in each child's home. There were three between group hypotheses formulated. If the two groups responded differently to all three stimuli, the inference would be that the children with autism have a general attention abnormality. Secondly, if the two groups differed in response to the cry and laugh stimuli but not to the tone, the inference would be that children with autism are responding differentially to stimuli that are social in nature. Finally, if children with autism differentially responded only to the cry stimulus, an empathic deficit hypothesis would be supported. It was hypothesized that children with autism would respond with heart rate acceleration (personal distress) to the cry stimulus. The results were inconsistent with all three between group hypotheses and the within group hypothesis. Rather results indicated a significant difference between the two groups in response to the laugh stimulus. Only the typically developing children had a significant deceleration response to the cry stimulus. However, the children with autism did not respond with an anxiety response to the cry stimulus as was hypothesized. The findings from this study suggest that at least some aspect of social function is intact in young children with autism. Results are interpreted in terms of a limbic-hypothalamic deficit hypothesis. Further investigations should include a larger sample size, more ecologically valid stimuli and concurrent behavioral response measures.

description: We provide a dispersion-theoretical representation of the reaction amplitudes $γK\to K π$ in all charge channels, based on modern pion-kaon $P$-wave phase shift input. Crossed-channel singularities are fixed from phenomenology as far as possible. We demonstrate how the subtraction constants can be matched to a low-energy theorem and radiative couplings of the $K^*(892)$ resonances, thereby providing a model-independent framework for future analyses of high-precision kaon Primakoff data.
