description: Energy is an important input in growing, processing, packaging, distributing, storing, preparing, serving, and disposing of food. Analysis using the two most recent U.S. benchmark input-output accounts and a national energy data system shows that in the United States, use of energy along the food chain for food purchases by or for U.S. households increased between 1997 and 2002 at more than six times the rate of increase in total domestic energy use. This increase in food-related energy flows is over 80 percent of energy flow increases nationwide over the period. The use of more energy-intensive technologies throughout the U.S. food system accounted for half of this increase, with the remainder attributed to population growth and higher real (inflation-adjusted) per capita food expenditures. A projection of food-related energy use based on 2007 total U.S. energy consumption and food expenditure data and the benchmark 2002 input-output accounts suggests that food-related energy use as a share of the national energy budget grew from 14.4 percent in 2002 to an estimated 15.7 percent in 2007.

description: We have developed a technique that extends static scanning electron microscopic imaging to include hyperspectral mapping of fast thermal and externally-driven movements at up to Megahertz frequencies. It is based on spectral analysis of the secondary electron flux generated by a focused electron beam incident on the moving object. We demonstrate detection of nanowire Brownian motion and hyperspectral mapping of stimulated oscillations of flea setae with deep sub-nanometer displacement sensitivity.

description: We study the decay of charged scalar and spinor fields around Reissner-Nordstrom black holes in de Sitter spacetime through calculations of quasinormal frequencies of the fields. The influence of the parameters of the black hole (charge, mass), of the decaying fields (charge, spin), and of the spacetime (cosmological constant) on the decay is analyzed. The analytic formula for calculation quasinormal frequencies for a large multipole number (eikonal approximation) is derived both for the spinor and scalar fieldss.

description: Many rural landowners within the Western United States do not have access to a secure water supply provided by a major dam or an irrigation district. Such water users must rely instead on groundwater pumping and/or seasonal water flows from tributaries. Some of these agricultural producers choose to store winter stream flows from tributaries within onsite reservoirs to secure their spring/summer water needs. However, regulatory agencies have increased restrictions on surface water storage and diversions to improve instream flows for endangered salmon, thus reducing water security for many landowners not located along the main stem. The majority of salmon habitat is within the tributaries located throughout a watershed. Most research regarding instream flows and water management, however, has focused on the main stem portion of a watershed and not on its tributaries. Such a focus ignores the important fact that most landowners are found off the main stem. Consequently, effective water management policies aimed at improving water security and salmon survivorship must focus on the main stem and the tributaries within a watershed. Our current research focuses on both of these critical areas. We Develop a spatially explicit economic model to analyze the demand for additional onsite storage with and without the existing regulatory restrictions. Using this model, we are able to determine which landowners have unmet demands for onsite storage versus those who prefer to pump groundwater, and thus would not request an appropriative water right for storage, even in the absence of a policy restriction.

description: This paper considers some thesis proposed by Maurice Merleau-Ponty during his lessons on sleeping and dreaming in the mid fifties, also with reference to the contemporary scientific debate. Dreaming and sleeping constitute a privileged perspective for considering the characteristic human interweaving of natural and cultural aspects, of animality and meaning. The immediate association of sleeping with a suspension of consciousness and with an absence of worldly contacts seems problematic. Furthermore the dualistic opposition between conscious activity and bodily passivity seems far less obvious. Besides it appears as not taken for granted that human acting and experiencing could be always considered as first person's phenomena.

description: We show that a quantum Otto cycle in which the medium, an interacting ultracold gas, is driven between a superfluid and an insulating phase can outperform similar single particle cycles. The presence of an energy gap between the two phases can be used to improve performance, while the interplay between lattice forces and the particle distribution can lead to a many-body cooperative effect. Since finite time driving of this cycle can create unwanted non-equilibrium dynamics which can significantly impair the performance of the engine cycle, we also design an approximate shortcut to adiabaticity for the many-body state that can be used to achieve an efficient Otto cycle around a critical point.

description: The inclusion of cover crops in cropping systems brings both direct and indirect costs and benefits. The literature has shown that cover crops can improve soil conservation and productivity, potentially improving cash crop yields and decreasing cash crop production costs. Farmers will adopt cover crops if the net economic benefit of utilizing them is positive. This study examines farmers’ willingness to grow cover crops as a soil conservation practice and to examine the socio-economic factors affecting their decision. Survey data collected in 2007-8 from Alabama farmers about cover crop adoption and management is utilized to estimate a cover crop adoption model.

description: The study investigated if Kolb’s and 5E learning models could improve teachers’ teaching quality in science education subjects such as biology, chemistry and physics. A sample of 298 students from 9 purposively selected secondary schools out of a population of 4,421 Senior Secondary II students from Makurdi Local Government Area of Benue State, Nigeria was used for the study. The study adopted quasi experimental research design of pretest, posttest and non-equivalent type. The instrument used for data collection was Science Education Teaching Quality Inventory (SETQI) with reliability value of 0.83 using Cronbach Alpha. Three research questions and three null hypotheses guided the study. The research questions were answered using Mean and Standard Deviation while the hypotheses were tested using Analysis of Covariance (ANCOVA). The study revealed that there was significant difference in the mean teaching quality scores of biology teachers as assessed by students taught biology using Kolb’s learning model (KLM), 5E learning model (5ELM) and discussion method (DM) [F2, 98=431.009, P<0.05]. It was found that there was significant difference in the mean teaching quality scores of chemistry teachers as assessed by students taught chemistry using KLM, 5ELM and DM [F2, 97=247.001, P<0.05]. It was revealed that there was significant difference in the mean teaching quality scores of physics teachers as assessed by students taught physics using KLM, 5ELM and DM [F2, 100=323.001, P<0.05]. It was recommended among others that serving science teachers should employ the use of Kolb’s and 5E learning models in other to enhance the quality of their teaching and invariably enhance students’ learning quality in Science Education.

description: There are many cases in which the “direction” of architecture seems to be indifferent to the architect who designs it. Among these, the Guggenheim Museum in New York by Frank Lloyd Wright is highly emblematic: through the long and troubled project’s phases it shows a surprising “reversibility”, horizontal and vertical. In most cases, however, the “direction” of architecture is determined by factors which are situated outside of it, as are existing buildings, or the circumstances of the site and the factors of exposure, lighting and ventilation. In this sense, architecture not only reveals the existence of differences but it builds them, becoming itself a system of differences.

description: We show that under general conditions there is at least one natural inflationary direction for the Kahler moduli of type IIB flux compactifications. This requires a Calabi-Yau which has h^{2,1}>h^{1,1}>2 and for which the structure of the scalar potential is as in the recently found exponentially large volume compactifications. We also need - although these conditions may be relaxed - at least one Kahler modulus whose only non-vanishing triple-intersection is with itself and which appears by itself in the non-perturbative superpotential. Slow-roll inflation then occurs without a fine tuning of parameters, evading the eta problem of F-term inflation. In order to obtain COBE-normalised density perturbations, the stabilised volume of the Calabi-Yau must be O(10^5-10^7) in string units, and the inflationary scale M_{infl} ~ 10^{13} GeV. We find a robust model independent prediction for the spectral index of 1 - 2/N_e = 0.960 - 0.967, depending on the number of efoldings.

description: Rankings of different risk management portfolios including Average Crop Revenue Election (ACRE), traditional government payment programs, crop insurance and hedging in futures; and optimal choices of insurance coverage levels and hedge ratios are evaluated for a representative central Indiana corn farm, using Monte Carlo simulation and optimization of expected utilities. The changes of preference between ACRE and traditional government programs under comprehensive scenarios of price and yield risks are studied. Also, Interactions between ACRE and other risk management instruments are examined, and government costs and risk management efficiencies between ACRE and traditional government programs are compared. The results show a strong preference of ACRE for the representative central Indiana corn farm in 2009, due to high ACRE guarantee price and expected drop in corn price from 2008 level. Even if the farm faces weak dependence between farm and aggregate yield, the risk could not offset the addition value ACRE could provide for this year. Also, it is found that there are synergistic effects between ACRE and two individual crop insurance plans but antagonistic effects between ACRE and group insurance plans. ACRE is more efficient than traditional government programs in terms of expected program costs.

The emphasis given by both authors to the intersection between directions and way, but also to the mutual subordination between thing and space, allows to rewrite the obituary of architecture as a spatial art, according to which the Modern Style has turned the spatiality into its specular visibility, into the spaciousness, into the indefinite continuity of the Bigness.

description: The space ${\Bbb{L}}$ of oriented lines, or rays, in ${\Bbb{R}}^3$ is a 4-dimensional space with an abundance of natural geometric structure. In particular, it boasts a neutral Kähler metric which is closely related to the Euclidean metric on ${\Bbb{R}}^3$. In this paper we explore the relationship between the focal set of a line congruence (or 2-parameter family of oriented lines in ${\Bbb{R}}^3$) and the geometry induced on the associated surface in ${\Bbb{L}}$. The physical context of such sets is geometric optics in a homogeneous isotropic medium, and so, to illustrate the method, we compute the focal set of the $k^{th}$ reflection of a point source off the inside of a cylinder. The focal sets, which we explicitly parameterize, exhibit unexpected symmetries, and are found to fit well with observable phenomena.

The neuroanatomy of extrastriate area 19 : a modular mosaic
Creators: name: Stewart, Tara H.
Publisher: name: University of British Columbia
Year: 2009

description: Studies of the primary visual cortex of the cat have been essential in establishing features of visual cortical organization that are fundamental to all mammalian species. One feature discovered in the cat is the presence of separate pathways that process different aspects of visual space in parallel. These parallel pathways can be defined by their organization with respect to the punctate pattern of cytochrome oxidase (CO) staining in the primary visual cortex (i.e. CO blob versus interblob). The extrastriate areas of the cat however, have not enjoyed such close scrutiny and the relationship between these areas and the parallel pathways is unknown. The aim of this study is to examine the modular organization of extrastriate area 19 (defined as a modular mosaic) in order to identify features which are shared with other mammalian species and which may be critical to overall extrastriate organization and function. Specifically, this study demonstrates that cells located in both the CO blobs and interblobs project to area 19, but they project to different regions or modules within area 19. Furthermore, it is found that intrinsic connections within area 19 form a patchy network. Two of the main recipients of projections from 19 are extrastriate areas LS and 21a. These two areas are distinguished physiologically: LS is responsive to motion, while 21a is sensitive to form (Dreher et al., 1996a). This study found that cells in area 19 that project to either 21a, or LS are organized in bands, which have spacing larger than the intrinsic patches. The bulk of the 21a and LS projection bands interdigitate, however regions that are less densely labeled tend to overlap. The characterization the contribution of parallel pathways to the modular mosaic in area 19 identifies several features of extrastriate cortical organization that may be shared by other mammals. First, the parallel pathways are not limited to the primary visual cortex but extend into extrastriate cortex. Second, these pathways are only partially segregated and with regions of convergence; this pattern is important, as it would allow for the efficiency of parallel processing while providing communication between the separate pathways.

The model is then applied to the development of a typology of feasible governance modes – market, hybrid, firm, or public bureau, considering levels of transaction costs and competencies of private firms. Theoretical and practical implications are discussed and future research opportunities are suggested.

description: By means of temperature and wavelength-dependent small-angle neutron scattering (SANS) experiments on sintered isotropic and textured Nd-Fe-B magnets we provide evidence for the existence of an anisometric structure in the microstructure of the textured magnets. This conclusion is reached by observing a characteristic cross-shaped angular anisotropy in the total unpolarized SANS cross section at temperatures well above the Curie temperature. Comparison of the experimental SANS data to a microstructural model based on the superquadrics form factor allows us to estimate the shape and lower bounds for the size of the structure. Subtraction of the scattering cross section in the paramagnetic regime from data taken at room temperature provides the magnetic SANS cross section. Surprisingly, the anisotropy of the magnetic scattering is very similar to the nuclear SANS signal, suggesting that the nuclear structure is decorated by the magnetic moments via spin-orbit coupling. Based on the computation of the two-dimensional correlation function we estimate lower bounds for the longitudinal and transversal magnetic correlation lengths.

description: Diquark correlations are important in baryons, which can be modeled as quark-diquark bound states. In addition, diquarks could play a role in non-standard hadrons such as tetraquarks and pentaquarks. Here, we obtain properties of these diquarks from the corresponding bound state equation, using a model for the effective quark-quark interaction that has proved successful in the light meson sector. Subsequently, we use the same model to estimate the masses of the lightest diquark-diquark and diquark-antidiquark states.

description: Investigation of size wage premium in earning’s literature neglects the important role played by technology adoption. This study models the size selection corrected earning’s function by introducing an extra dimension of selection of technology complexity, using a sample from workers in US hog farms. The estimated wage gap between large and small farms is reduced once correction in selection is controlled. Workers compensate monetary income for better work environment, better health and more job security, in which large farms and technologically advanced farms have advantages.
Many-Body Effects and Optical Properties of Single- and Double Layer $α$-$\mathcal{T}_3$ Lattices

description: An extensive analytical and numerical investigation has been carried out to examine the role played by many-body effects on various $α$-$\mathcal{T}_3$ materials under an off-resonance optical dressing field. Additionally, we explore its dependence on the hopping parameter $α$ as well as the electron-light coupling strength $λ_0$. The obtained dressed states due to mutual interaction between Dirac electrons and incident light are shown to demonstrate rather different electronic and optical properties in comparison with those in the absence of incident light. Specifically, various collective transport and optical properties of these electron dressed states are discussed in detail and compared for both single- and double layer $α$-$\mathcal{T}_3$ lattices. All of these novel properties are due to the presence of a middle flat band and the interband transitions between it and an upper conduction band. Also, coupled plasmon dispersions for interacting double layer $α$-$\mathcal{T}_3$ lattices are calculated, revealing a lower acoustic-like plasmon branch with tunable group velocity determined by both the layer separation and Fermi energy of each layer. Finally, a many-body theory is presented within the random-phase approximation for calculating the optical absorbance of doped multi-layered $α$-$\mathcal{T}_3$ lattices in a linearly-polarized light field. We anticipate that the discoveries reported here could impact the design of the next-generation nano-optical and nano-plasmonic devices.

Observations were obtained in the broad F205W filter ($\sim$ K) and in the medium-wide bands F171M and F180M, the latter which cover strong molecular absorption features in cool stars. The new data, together with previously obtained HST/NICMOS images in the F110W ($\sim$ J) and F160W ($\sim$ H) filters, provide a census of the cool stellar population in this chemically unevolved galaxy. We find that stars as old as $\sim 1$ Gyr are required to explain the observed colour-magnitude diagrams. Combining broad and medium-wide band photometry, we have classified the observed stars. The observed stellar populations, to the depth of our data, are dominated by luminous red supergiant stars. However, an intermediate-age component is also present. We have identified carbon star candidates, and show that they dominate the stellar content for intermediate mass and age. We show that low metallicity intermediate-age stars have, for a given colour, a F110W ($\sim$ J-band) excess compared to local carbon stars. The carbon stars identified in IZw18 are the most distant (more than 10 Mpc) resolved examples yet discovered.

Ri-orientare il sensibile. Percorsi dello sguardo e direzionalità dell’immagine in Picasso

description: A work about axis of vision, vertical vs horizontal, and on direction of image, front vs back, guides some observations, developing in the image space, that Picasso elaborates on representation. The essay proposes a close look to some artworks in which the speculation on above-written oppositions, is functional to “present» the representation. The issue concerns not solely reversals acting on orientation of represented world objects, but axis participating in rewriting the culturally prefigured orientation of painting and writing and in considering the «shape-of-picture» and image margins.

description: At the end of the 1960s “Supports/Surfaces” artists start deconstructing paintings to jeopardize their representational qualities. Claude Viallat and Daniel Dezeuze, for example, process canvases and frames to highlight their phisical aspect as opposed to the illusionistic realm or representation. This way polarities such as form/space and illusionistic space/real space start having a new, dialectic relationship.

description: We discuss our implementation of dynamical Ginsparg-Wilson type fermions using a stout-smeared chirally improved Dirac operator. Such operators have been studied extensively in quenched calculations within the Bern-Graz-Regensburg (BGR) collaboration. Here we discuss the development and testing of the Hybrid Monte Carlo algorithm with this Dirac operator. We study the chiral properties of this operator in a dynamical setup, comparing, e.g., the spectra of the operator for the dynamical and quenched cases. We then discuss quantitative features of the algorithm like autocorrelation and performance.

description: Nanozymes are nanomaterials with intrinsic magnetism and superparamagnetic properties. In the presence of an external magnet, nanozyme particles aggregate and redisperse without a foreign attraction. We evaluated the performances of nanozyme by changing the biosensing platforms and substituting other biological variants for a complete cancer assay detection. We investigated the expression of morphological variants in the transmission of signals using an electrochemical method. The signal responses, including signal enhancement with the nanozyme (Au-Fe2O3), showed a wide capturing range (greater than 80%, from 102 to 105 cells ml−1 in phosphate-buffered saline buffer, pH 7.4). The platform showed a fast response time within a dynamic range of 10–105 cells ml−1 for the investigated T47D cancer cell line. We also obtained higher responses for anti-HER2 (human epidermal receptor 2)/streptavidin interface as the biosensing electrode in the presence of T47D cancer cells. The positive assay produced a sixfold increase in current output compared to the negative target or negative biological variant. We calculated the limit of detection at 0.4 U ml−1, and of quantitation at 4 U ml−1 (units per millilitre). However, blood volume amounts in clinical settings may constrain diagnosis and increase detection limit value significantly.
Destra e sinistra nello spazio iconico tra iconografia cristiana e antropologia

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: Proceeding from the statement that «reading» images is not at all analogous to any culturally codified lecture of written texts, Sigrid Weigel develops a crucial critic of the anthropological paradigm linked to the left-right problem in the visual arts. Focusing on various examples of painted and sculpted Annunciations, the author argues how the decline of the traditional orientation, based on the figure of God in central position, leads to a growing importance of the spectator gaze and to a new relation between iconic narration and symbolic meaning.

description: The effective interaction of a pseudoscalar particle with photon in plasma with the presence of a constant uniform magnetic field is investigated. It is shown that under some physical conditions the effective coupling between pseudoscalar particle and photon does not depend on medium parameters and particles momentum. The probability of the familon decay into photon pair in a strongly magnetized degenerate ultrarelativistic plasma is calculated.

description: Recent outbreaks of highly pathogenic avian influenza (HPAI) in Asia, Europe, and Africa have caused severe impacts on the broiler sector through production losses, trade restrictions and negative shocks to demand. This study develops a multimarket econometric model that is the basis of simulations to assess the spread and market implications of a potential HPAI outbreak in U.S. broiler industry. It takes into account market power that might exist within the livestock and meat sectors and endogenizes the optimal production condition on the model system. The results imply that the HPAI shocks affect prices at different marketing levels unequally and change the price margins along the supply chain with the existence of market power. The change in the price margin, although statistically significant, is quite small in absolute value.

description: The issue of modeling farm financial decisions in a dynamic framework is addressed in this paper. Discrete stochastic programming is used to model the farm portfolio over the planning period. One of the main issues of discrete stochastic programming is representing the uncertainty of the data. The development of financial scenario generation routines provides a method to model the stochastic nature of the model. In this paper, two approaches are presented for generating scenarios for a farm portfolio problem. The approaches are based on copulas and optimization. The copula method provides an alternative to the multivariate normal assumption. The optimization method generates a number of discrete outcomes which satisfy specified statistical properties by solving a non-linear optimization model. The application of these different scenario generation methods is then applied to the topic of geographical diversification. The scenarios model the stochastic nature of crop returns and land prices in three separate geographic regions. The results indicate that the optimal diversification strategy is sensitive to both scenario generation method and initial acreage assumptions. The optimal diversification results are presented using both scenario generation methods.

description: A 2-D finite volume Computational Fluid Dynamic (CFD) model, using Ansys Fluent vR.1 of a vertically oriented upwards continuous casting (VUCC), was investigated for 8 mm, oxygen free copper (OFCu). The simulations enabled the mapping of the cast OFCu solidification front (SF) interface from liquid to solid. Optimisation of the simulation parameters were investigated which included mesh size and the Ansys specific ‘mushy zone’ constant (Amush), which is used to account for fluid flow dampening at SF within the model. Observations of the SF, the change in fluid volume in the die, the simulation convergence and the total simulation time, revealed that the optimised casting parameters were for mesh size 1×10-4 m and Amush 106 kg/m3s. These parameters were compared with the cast rod and highlighted qualitatively the relationship between grain growth direction and SF position during a casting pulse cycle.

description: This paper focuses on differentials between rental and owner costs as a primary determinant of local homeownership. In simultaneous equations to estimate the separate effects of owner cost and rent on homeownership rates, the control variables are various household and geographical factors (Census 2000 tract level dataset), in the samples of 48 contiguous states within the United States. The results show negative effects of rental and owner costs on homeownership rates. Ethnicity, income, age, property tax rate and loan usage rates, contribute to increased owner costs. Several factors had significant association with the rise in housing prices before 2006.

description: The question of laterality lies at the core of the image description technique in Diderot’s Salons. This essay aims at examining the role of laterality through a close analysis of Diderot’s commentaries of some artistic works. It is possible to recognize the role of laterality in the beholder’s gaze, in the aesthetic re-creation during the process of reception and, finally, in the inversion of left and right as productive development of the artistic image.
