description: Ethanol production is increasingly commonplace in many grain producing regions. This paper uses the grain producing region of Western Australia as a case study to illustrate how the location and size of an ethanol plant affects its grain accumulation costs. Specifically, this study examines how price variability of various wheat grades, combined with spatial and temporal variability in production of those grades affects the costs of grain accumulation for ethanol production. These costs are the main component of a plant's operating costs so lessening these costs can offer a comparative advantage for a plant owner. Logistics models' based on mathematical programming were constructed to depict a range of plant sizes and locations for ethanol production. The key findings from analysis of the models' output are that, in some cases, large cost savings in grain accumulation costs are possible through locating ethanol plants at a sub-set of southern locations in the Albany, Kwinana and Esperance grain receival zones of Western Australia. The southern inland site of Newdegate, in particular, offers the greatest potential savings in costs of grain accumulation, displaying the lowest certainty equivalent of these costs when compared to all other locations. At all locations, small to medium-sized plants offer advantages of lower and less variable costs of grain accumulation.
The population structure of Armillaria ostoyae in the central and southern interior of British Columbia

description: The population structure of Armillaria ostoyae (Romagn.) Herink and Armillaria sinapina Berube & Dessureault was studied at two sites in the Interior of British Columbia using Random Amplified Polymorphic DNA (RAPD) analysis and somatic incompatibility testing. The first study site contained a small number of relatively large genets of Armillaria ostoyae. Each distinct infection center was occupied by a single genet of A. ostoyae, one of which displayed signs of a somatic mutation. Armillaria sinapina was also sampled from the first site but its population structure was considerably different from that of A. ostoyae. The second study site contained high densities of relatively small genets of A. ostoyae. It was estimated that over 70 % of the genets in this population occupied a domain less than one hectare in area. The distribution of genets could not be predicted by the distribution of mortality. The results of somatic incompatibility testing used to differentiate between genets corresponded with the results of RAPD analysis, with only one discrepancy. For both sites, regression analysis indicated no significant linear relationship between geographic distance and genetic similarity of genets.

description: The dual class shareholding company has been adopted as a way of managing the single desk operating system for wheat in Australia. Using B Class ASX listed shares to fund the operation of the company, and the use of A Class grower held shares to control the direction of the company, the objectives of the current arrangements are to maximise net pool returns to growers. Using principal-agent theory, the current marketing arrangements are examined. Considering both groups of shareholders as principals of one agent, this paper has focused on examining the contracts between the agent and each principal, and the incentives provided by these contracts to the agent to act in the interests of each of the shareholder groups. The reward to the agent from each principal is examined, and it is found that the ultimate objective of the company may not be fulfilled by the current marketing arrangements, which will incur agency costs to at least one group of shareholders. It is suggested that a reformulation of the remuneration model is required in order to reduce the risk that the objectives of both groups of shareholders are not met.

description: Queinnectrechus fabbrii, new species of trechine beetle from the Zheduo Shan Mountains (Sichuan, south-western China), is described. Specimens of the new taxon have been sampled on the western slopes of the mountain at 4300-4500 m, in alpine pastures with Rhododendron. The new species is sympatric, but not syntopic, in the same mountain with two other Queinnectrechus species, i.e. Q. zheduoshanus Uéno, 1998 and Q. glacialis Uéno, 1998, both of them living on the eastern slopes, the first at 3250 m, in forest, and the second on moraines at 3870-3920 m, respectively. Morphological and diagnostic features of the new taxon are described and illustrated. Furthermore, a key is given for identification of the closely related species of the genus, known so far from the Gongga Shan massif and its vicinities.

Higher Derivative Operators from Scherk-Schwarz Supersymmetry Breaking on T^2/Z_2

description: In orbifold compactifications on T^2/Z_2 with Scherk-Schwarz supersymmetry breaking, it is shown that (brane-localised) superpotential interactions and (bulk) gauge interactions generate at one-loop higher derivative counterterms to the mass of the brane (or zero-mode of the bulk) scalar field. These brane-localised operators are generated by integrating out the bulk modes of the initial theory which, although supersymmetric, is nevertheless non-renormalisable. It is argued that such operators, of non-perturbative origin and not protected by non-renormalisation theorems, are generic in orbifold compactifications and play a crucial role in the UV behaviour of the two-point Green function of the scalar field self-energy. Their presence in the action with unknown coefficients prevents one from making predictions about physics at (momentum) scales close to/above the compactification scale(s). Our results extend to the case of two dimensional orbifolds, previous findings for S^1/Z_2 and S^1/(Z_2 x Z_2') compactifications where brane-localised higher derivative operators are also dynamically generated at loop level, regardless of the details of the supersymmetry breaking mechanism. We stress the importance of these operators for the hierarchy and the cosmological constant problems in compactified theories.

description: The saltopteran fauna of Portugal was studied between 1992-2000. Sampling took place during field tlips, lasting yearly 5 to 14 days. Several southern, central and northern regions were visited at different times of the year. In total, 76 species (31 of Ensifera and 45 of Caelifera) were recorded, from which a C/E quotient of 1.45 was calculated. For some of the species caught, the song of the male was presented as additional taxonomic character. First records were made for nine species: Tylopsis lilifolia, Conocephalus conocephalus, Platycleis falx laticauda, two Ctenodecticus spp., Mogoplistes brunneus, Tetrix subulata, Paracimena t. bisignata. Uromenus anapaulae was found as new species and described. Using literature data, the species of Saltatoria previously mentioned for Portugal were listed, and some notes added for insufficiently known species. The biogeography of the saltatoria fauna of Portugal is discussed in relation to its origin with the result that 19 (25%) specis are endemic for the Iberian Peninsula.

Measurement of the Higgs boson production rate in association with top quarks in final states with electrons, muons, and hadronically decaying tau leptons at $\sqrt{s} =$ 13 TeV

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The rate for Higgs (H) bosons production in association with either one (tH) or two ($\mathrm{t\bar{t}}$H) top quarks is measured in final states containing multiple electrons, muons, or tau leptons decaying to hadrons and a neutrino, using proton-proton collisions recorded at a center-of-mass energy of 13 TeV by the CMS experiment. The analyzed data correspond to an integrated luminosity of 137 fb$^{-1}$. The analysis is aimed at events that contain H $\to$ WW, H $\to$ $ττ$, or H $\to$ ZZ decays and each of the top quark(s) decays either to lepton+jets or all-jet channels. Sensitivity to signal is maximized by including ten signatures in the analysis, depending on the lepton multiplicity. The separation among the tH, the $\mathrm{t\bar{t}}$H, and the backgrounds is enhanced through machine-learning techniques and matrix-element methods. The measured production rates for the $\mathrm{t\bar{t}}$H and tH signals correspond to 0.92 $\pm$ 0.19 (stat) $^{+0.17}_{-0.13}$ (syst) and 5.7 $\pm$ 2.7 (stat) $\pm$ 3.0 (syst) of their respective standard model (SM) expectations. The corresponding observed (expected) significance amounts to 4.7 (5.2) standard deviations for $\mathrm{t\bar{t}}$H, and to 1.4 (0.3) for tH production. Assuming that the Higgs boson coupling to the tau lepton is equal in strength to its expectation in the SM, the coupling $y_{\mathrm{t}}$ of the Higgs boson to the top quark divided by its SM expectation, $κ_\mathrm{t}$ = $y_\mathrm{t} / y_\mathrm{t}^\mathrm{SM}$, is constrained to be within $-$0.9 $\lt$ $κ_\mathrm{t}$ $\lt$ $-$0.7 or 0.7 $\lt$ $κ_\mathrm{t}$ $\lt$ 1.1, at 95% confidence level. This result is the most sensitive measurement of the $\mathrm{t\bar{t}}$H production rate to date.

In quattro stazioni di raccolta è stata riscontrata una comunità di elevata ricchezza tassonomica, alla quale contribuivano taxa stenoeci con valore di indicatori e/o di importanza biogeografica. I popolamenti sono apparsi differenti nelle varie stazioni e nelle diverse stagioni, mostrando nel complesso una relazione inversa tra ricchezza tassonomica e abbondanza del taxon dominante. La diversità tassonomica era più elevata nelle stazioni a maggiore altitudine, caratterizzate da sedimenti grossolani, mentre una sensibile riduzione del numero di taxa è stata osservata lungo l’asta fluviale, dove è apparsa evidente la dominanza di taxa eurieci. La diversità della comunità macrobentonica osservata dimostra l’importanza faunistica ed ecologica del tratto pedemontano del fiume Metauro, evidenziando l’opportunità di una sua gestione attenta alla tutela e alla conservazione.

description: Prawn culture has been playing an important economic role in Vietnam for the last two decades. The area for aquaculture is continuously expanding in the provinces of the Mekong Delta. Fisheries and aquaculture contributed 29.2 per cent to the GDP component of the agricultural sector in the Mekong Delta in 2003. However, data from previous studies shows that more than 30 per cent of the total prawn farms are experiencing economic loss. Profitability can be increased by increasing yield through development and adoption of new technologies and improvement in the economic efficiency of prawn farming operations. This paper examines the technical efficiency of prawn farming in the Mekong Delta of Vietnam using the stochastic production frontier approach. The estimated mean technical efficiency for 193 sampled prawn farms was 46 per cent. Experience in prawn farming and the age of the farmers, as well as their education, are some of the factors that were found to affect technical efficiency. The prawn farms operated by more experienced, but younger prawn growers were found to attain higher technical efficiency.

description: Constriction-based Josephson weak-links display a thermal bi-stability between two states exhibiting zero and finite voltages. This manifests in experiments either as hysteresis in weak-links current voltage characteristics or as random telegraphic signal in voltage. In the latter case, a noise-driven amplification of a sinusoidal excitation of the device is observed, at frequencies matching the characteristic switching frequency in telegraphic signal, a phenomenon known as stochastic resonance. The observed behavior is understood using a two-state model of stochastic resonance and is exploited to illustrate an enhanced signal-to-noise-ratio in a micro-SQUID as a magnetic field sensor.

description: This article compares the effects of various fiscal policies on choices of development timing and capital intensity when rents on housing follow geometric Brownian motion with those when rents follow arithmetic Brownian motion. These policy instruments include fees on capital, housing, and land, and taxes on urban income, and properties both before and after development. Regardless of the motion of rents, when one choice is fixed, the effects of these policy instruments on the other choice are qualitatively the same. When the two choices are determined endogenously, although these policy instruments exhibit the same qualitative effect on the choice of development timing, they may exhibit different effects on the choice of capital intensity if rents on housing follow different types of motions.

description: Using a multi-scaled, chaotic flow known as the KS model of turbulence, we investigate the dependence of Lyapunov exponents on various characteristics of the flow. We show that the KS model yields a power law relation between the Reynolds number and the maximum Lyapunov exponent, which is similar to that for a turbulent flow with the same energy spectrum. Our results show that the Lyapunov exponents are sensitive to the advection of small eddies by large eddies, which can be explained by considering the Lagrangian correlation time of the smallest scales. We also relate the number of stagnation points within a flow to the maximum Lyapunov exponent, and suggest a linear dependence between the two characteristics.

description: Experiments and simulations from a variety of sample sizes indicated that the centrifugal force significantly affects rotating Rayleigh-Bénard convection-patterns. In a large-aspect-ratio sample, we observed a hybrid state consisting of domain chaos close to the sample center, surrounded by an annulus of nearly-stationary nearly-radial rolls populated by occasional defects reminiscent of undulation chaos. Although the Coriolis force is responsible for domain chaos, by comparing experiment and simulation we show that the centrifugal force is responsible for the radial rolls. Furthermore, simulations of the Boussinesq equations for smaller aspect ratios neglecting the centrifugal force yielded a domain precession-frequency $f\simε^μ$ with $μ\simeq1$ as predicted by the amplitude-equation model for domain chaos, but contradicted by previous experiment. Additionally the simulations gave a domain size that was larger than in the experiment. When the centrifugal force was included in the simulation, $μ$ and the domain size closely agreed with experiment.

description: This paper examines the extent of, and factors associated with, Indonesian deforestation caused by small scale farmers. A survey of 216 rural households in five villages in East Kalimantan, Indonesia, was conducted to study to what extent forest dependence and various facets of poverty encourage people to clear forestland. Results indicate that households that rely on forests for cash and in-kind income (from activities such as hunting and firewood collection) are less likely to clear forests for agricultural use. Forest clearing is also negatively related to the availability of off-farm employment. An important finding is that poorer farmers are less likely to engage in forest clearing.

description: We show that the nature of the topological fluctuations in $SU(3)$ gauge theory changes drastically at the finite temperature phase transition. Starting from temperatures right above the phase transition topological fluctuations come in well separated lumps of unit charge that form a non-interacting ideal gas. Our analysis is based on a novel method to count not only the net topological charge, but also separately the number of positively and negatively charged lumps in lattice configurations using the spectrum of the overlap Dirac operator. This enables us to determine the joint distribution of the number of positively and negatively charged topological objects, and we find this distribution to be consistent with that of an ideal gas of unit charged topological objects.

description: Surveillance programs on farms and in the local environment provide an essential protection against the importation and spread of exotic diseases. Combined with border quarantine measures, these programs protect both consumers and producers from major health concerns and disease incursions that can potentially destroy local agricultural production and supporting industries, as well as generate substantial losses in trade and tourism. However, surveillance programs also impose costs in the form of expenditures on the surveillance program itself, along with the costs of disease management and eradication should an incursion occur. Taking border quarantine expenditures as given, this paper develops a stochastic optimal control model (with a jump-diffusion process) to determine the optimal level of surveillance activity against a disease incursion by minimizing the present value of the major direct and indirect costs of the disease, as well as the cost of the surveillance and disease management and eradication programs. The model is applied to the case of a potential entry and spread of Foot-and-Mouth Disease in the United States. Results show that current surveillance expenditures are far less than optimal.

These include interpolating ensemble matrices, where the interval of the independent random parameters are restricted, pseudo-random operators, where there are far fewer random parameters than required for random matrices, and quantum chaotic evolution. Restricting randomness in different ways allows us to probe connections between entanglement and randomness. We comment on which properties affect entanglement generation and discuss ways of efficiently producing random states on a quantum computer.

description: The net present value (NPV) of downstream economic benefits of changes in water-yield (W) and salt-load (S) of mean annual river flow received by a lower catchment from an upper catchment are described as a 3-dimensional (NPV,W, S) surface, where dNPV/dW > 0 and dNPV/d(S/W) < 0. Upstream changes in land use (i.e. forest clearing or forest establishment, which result in higher or lower water-yields, respectively) are driven by economic consequences for land owners. This paper defines conditions under which costs of strategic upstream land use changes could be exceeded by compensations afforded by downstream benefits from altered water-yields and/or lower salt loads. The paper presents methods, and preliminary calculations for an example river, quantifying the scope for such combinations, and raising the question of institutional designs to achieve mutually beneficial upstream and downstream outcomes. Examples refer to the Macquarie River downstream of Dubbo, NSW, and Little River, an upstream tributary.

description: Phase diagram of strongly interacting matter is discussed within the exactly solvable statistical model of the quark-gluon bags. The model predicts two phases of matter: the hadron gas at a low temperature T and baryonic chemical potential muB, and the quark-gluon gas at a high T and/or muB. The nature of the phase transition depends on a form of the bag mass-volume spectrum (its pre-exponential factor), which is expected to change with the muB/T ratio. It is therefore likely that the line of the 1st} order transition at a high muB/T ratio is followed by the line of the 2nd order phase transition at an intermediate muB/T, and then by the lines of "higher order transitions" at a low muB/T.

description: The diverse range of resources which underlie the utility of quantum states in practical tasks motivates the development of universally applicable methods to measure and compare resources of different types. However, many of such approaches were hitherto limited to the finite-dimensional setting or were not connected with operational tasks. We overcome this by introducing a general method of quantifying resources for continuous-variable quantum systems based on the robustness measure, applicable to a plethora of physically relevant resources such as optical nonclassicality, entanglement, genuine non-Gaussianity, and coherence. We demonstrate in particular that the measure has a direct operational interpretation as the advantage enabled by a given state in a class of channel discrimination tasks. We show that the robustness constitutes a well-behaved, bona fide resource quantifier in any convex resource theory, contrary to a related negativity-based measure known as the standard robustness. Furthermore, we show the robustness to be directly observable -- it can be computed as the expectation value of a single witness operator -- and establish general methods for evaluating the measure. Explicitly applying our results to the relevant resources, we demonstrate the exact computability of the robustness for several classes of states.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article, we calculate the axial and the induced pseudoscalar form-factors $G_A(t=-Q^2)$ and $G_P(t=-Q^2)$ of the nucleons in the framework of the light-cone QCD sum-rules approach up to twist-6 three valence quark light-cone distribution amplitudes, and observe that the form-factors $G_A(t=-Q^2)$ and $G_P(t=-Q^2)$ at intermediate and large momentum transfers with $Q^2> 2 GeV^2$ have significant contributions from the end-point (soft) terms. The numerical values for the axial form-factor $G_A(t=-Q^2)$ are compatible with the experimental data and theoretical calculations, for example, the chiral quark models and lattice QCD. The numerical values for the induced pseudoscalar form-factor $G_P(t=-Q^2)$ are compatible with the calculation from the Bethe-Salpeter equation.

description: That residents of Zimbabwe's Communal Areas (CAs) obtain a variety of goods and services from their natural woodlands has long been recognized. Little was known however, of the value or preferences of CA residents for these goods and services. This paper describes a study, carried out in mid-1991, to elicit the preferences of residents of CAs for the goods and services they derived from trees. A new approach to eliciting preferences and establishing monetary values for the non-market goods and services was developed and administered to a total of 369 households in three CAs. Scores given to tree-derived goods and services were indexed to an anchor (a borehole) for which a willingness to pay (WTP) estimate was elicited. A similar instrument, but without the WTP questions, was administered to 39 professionals involved in research, management, or administration of indigenous woodlands. Of the goods and services derived from trees CA residents valued fuelwood, farm and household materials, inputs to crop production, animal feed and ecological services most highly. Mean capital value to a household of the tree-derived goods and services was Z$1678. Using a 4% discount rate this capital could yield average annual household incomes of between 45 and 60% of the average incomes derived from agricultural activities. Differences in values between residents in high and low tree cover sites were used to estimate the per household loss in capital value of reductions in tree cover. These amounted to about Z$700 per household or about 50% of the mean total value in high tree cover sites. Professionals assigned a higher total value to tree derived goods and services than did CA residents. Professionals and CA residents also assigned different values to several of the categories of tree derived goods and services. The results had a number of implications for research and policy. Indigenous woodlands provide a significant source of household income whose value is not reflected in markets. Lack of understanding of the productivity of indigenous woodlands as well as the poor understanding of the impacts of management on woodlands were seen as major factors inhibiting their efficient and sustained use. Research, management and policy need to focus on enhancing the ability of CA residents to effectively manage their woodlands. This objective requires that researchers develop; a) a clear understanding of the values, needs and objectives of CA residents; b) reliable technical knowledge on the growth, production and reproduction of indigenous woodlands; c) a clear understanding of the institutions controlling the access to, and the use of, indigenous woodlands in the CAs of Zimbabwe.

description: Let X be a right-angled building. We show that the lattices in Aut(X) share many properties with tree lattices. For example, we characterise the set of covolumes of uniform and of nonuniform lattices in Aut(X), and show that the group Aut(X) admits an infinite ascending tower of uniform and of nonuniform lattices. These results are proved by constructing a functor from graphs of groups to complexes of groups.

AN EXPLORATORY STUDY OF THE MARKETING PROCESSES OF CONSUMER FOOD PRODUCT MARKETERS
Creators: name: Wadsworth, Frank Howard
name: Wadsworth, Frank Howard
Publisher: name: Unknown
Year: 1991
Subjects: subject: Marketing
subject: FOS: Economics and business

description: Increased rivalry in the food industry has led existing food marketers to change from a 'commodity' to a 'marketing' business orientation. This research investigates the marketing process as implemented by several consumer food product marketers. A model of the marketing process was developed using marketing literature and discussions with academicians. Field interviews with consumer food product marketers were conducted to determine their marketing processes and activities. Interview results reveal that although marketers use the same components of the marketing process model, the extent to which these components are used varies substantially. Commodity-oriented firms use fifty percent of the model's elements, while marketing-oriented firms use ninety percent. Marketing-oriented firms also use more disaggregated and in-depth data as well as formal analyses in making their marketing decisions.

description: The novel nickelate superconductors of infinite-layer type feature challenging electronic pecularities in the normal-state phase diagram with doping. Distinct many-body behavior and different dispersion regimes of the entangled $\{$Ni-$d_{z^2}$, Ni-$d_{x^2-y^2}$$\}$ orbital sector give rise to highly rich physics, which is here studied for the case of the NdNiO$_2$ system. An analysis based on advanced realistic dynamical mean-field theory unveils that the superconducting hole-doped region is the meeting place of a (self-)doped Mott insulator from the underdoped side, and a bad Hund metal from the overdoped side. Fermi-level crossing of the Ni-$d_{z^2}$ flat-band ties both regimes together to form a singular arena for unconventional superconductivity. We furthermore shed light on the intriguing problem of elusive magnetism in infinite-layer nickelates. Antiferromagnetic (AFM) order with small Ni moments is shown to be a vital competitor at low temperature. At stoichiometry, C-AFM order with ferromagnetic spin-alignment along the $c$-axis benefits from a conceivable coexistence with Kondo(-lattice) screening.

description: Th(IV) hydration in aqueous solution is studied by means of molecular dynamics simulations based on a polarisable Th(IV)-H2O interaction potential developed in the framework of the hydrated ion concept. Molecular Dynamics (MD) simulations provide as the only in-solution representative motif the ennea-aqua ion, [Th(H2O)9]4+, with first shell water molecules at an average distance of 2.47 Å from the ion, in accordance with most of the experimental estimates. A well-defined second hydration shell is also identified, hosting ca. 19 solvent molecules at 4.65 Å. Non-structural aspects of the Th(IV) hydration phenomenon, such hydration enthalpy and ion diffusion are well reproduced by the simulation results. The analysis of the O-Th-O angle distribution suggests that the capped square antiprism arrangement prevails over the trigonal tricapped prism. The well-balanced definition of the ion–water and water–water interactions in such a demanding ion neighbourhood is confirmed by the EXAFS and XANES spectroscopies. The theoretical spectra, computed from the MD trajectory, are in fine agreement with some of the experimentally recorded. The sensitivity of the XAS spectroscopy to structural changes confirms how the presented potential manages in a proper way the response of the water molecules to the highly polarising electric field generated by the tetravalent ion.
A NEW TRICHOTAENIA SPECIES FROM TANZANIA (COLEOPTERA, CICINDELIDAE)
Creators: name: Cassola, Fabio
Publisher: name: Fragmenta Entomologica
Year: 2008

description: Trichotaenia kudrnai n. sp., is described from Mpanda, Rukwa, Tanzania. By having a partially hairy labrum, it is obviously a member of group 2 (species of group 1 have a glabrous labrum instead), and in particular it is apparently closely allied to T. rivalieri Basilewsky, 1958, however differing from it because of several important morphological characters, such as the different patterns of elytral and pronotal pubescence, the shorter pronotum with more apparent notopleural sutures and the even stronger elytral sculpture.
