description: Charged particles scattering on moving inhomogenities of the magnetised interstellar medium can gain energy through the process of second-order Fermi acceleration. This energy gain depletes in turn the magnetic wave spectrum around the resonance wave-vector $k\sim 1/R_L$, where $R_L$ is the Larmor radius of the charged particle. This energy transfer can prohibit the cascading of magnetic turbulence to smaller scales, leading to a drop in the diffusion coefficient and allowing the efficient exchange of charged dark matter particles in the disk and the halo. As a result, terrestial limits from direct detection experiments apply to charged dark matter. Together with the no-observation of a drop in the diffusion coefficient, this excludes charged dark matter for $10^3 GeV\lesssim m/q \lesssim 10^{11} GeV$, even if the charged dark matter abundance is only a small part of the total relic abundance.

description: We propose a generalized structure of Bell inequalities for arbitrary d-dimensional bipartite systems, which includes the existing two types of Bell inequalities introduced by Collins-Gisin-Linden-Massar-Popescu [Phys. Rev. Lett. 88, 040404 (2002)] and Son-Lee-Kim [Phys. Rev. Lett. 96, 060406 (2006)]. We analyze Bell inequalities in terms of correlation functions and joint probabilities, and show that the coefficients of correlation functions and those of joint probabilities are in Fourier transform relations. We finally show that the coefficients in the generalized structure determine the characteristics of quantum violation and tightness.

description: Growing demand for high-value food commodities is opening up opportunities for farmers, especially smallholders to diversify towards commodities that have strong potential for higher returns to land, labour and capital. But, there is an apprehension about the capability of smallholders to participate in the market-oriented production due to their lack of access to markets, capital, inputs, and technology and extension services. In this paper, possibilities have been explored of linking smallholders to markets through such institutions as cooperatives, growers’ associations and contract farming that reduce marketing and transaction costs and alleviate some production constraints. Evidence has shown that smallholders do participate and make a sizeable contribution to the production of high-value food commodities, but their links to markets are not strong. Though market institutions like cooperatives, contract farming and growers’ associations do not altogether ignore smallholders, some policy support is imperative to strengthen their linkages with the markets.

description: The evolution of static dielectric constants and polarization with doping are analyzed and discussed using established experimental results. The variation of screened Coulomb potential with doping is derived theoretically to justify the said evolutions. The latter justification arises due to the influence of ionization energy ($\mathcal{E_I}$) on the static dielectric functions. The bare Coulomb potential and the Thomas-Fermi screened potential with finite carrier density were recovered when $\mathcal{E_I} \to \infty$ and $\mathcal{E_I} \to E_F^0$ respectively. Basically, these phenomenological models are associated with the ionization energy based Fermi-Dirac statistics (iFDS).

description: Both continuous and discontinuous precipitation is known to occur in CuAg alloys. The precipitation of Ag-rich phase has been experimentally investigated by atom probe tomography and transmission electron microscopy after ageing treatment of Cu-5%wtAg at 440$^\circ$C during 30'. Both continuously and discontinuously formed precipitates have been observed. The precipitates located inside the grains exhibit two different faceted shapes: tetrahedral and platelet-shaped precipitates. Dislocations accommodating the high misfit at the interface between the two phases have also been evidenced. Based on these experimental observations, we examine the thermodynamic effect of these dislocations on the nucleation barrier and show that the peculiar shapes are due to the interfacial anisotropy. The appropriate number of misfit dislocations relaxes the elastic stress and lead to energetically favorable precipitates. However, due to the large misfit between the parent and precipitate phases, discontinuous precipitation that is often reported for CuAg alloys can be a lower energetic path to transform the supersaturated solid solution. We suggest that the presence of vacancy clusters may assist intragranular nucleation and decrease

description: The Indian food retail sector is one of the biggest industries in the country with an annual turnover of around US $18 billion. It has been estimated that organized food retailing in India which is worth US $ 666 million today will increase to US $ 33,333 million by 2015. The inherent attractiveness of the segment is luring more and more investors from both India and abroad, as is clearly indicated by the opening of a number of retail stores by major corporate houses like those of Bharti, Reliance, Pantaloons (Food Bazaar), Subhiksha, ITC (Choupal fresh), etc. However, to build long-term customer loyalty, price, quality, variety, and right image are very much needed. To attain this, the aesthetic appeal of the store and the way the products are displayed at the store are very important. Thus, the visual merchandising (VM) is the need of the hour at the food retail stores. This paper has studied various components of VM at retail stores and has analyzed the impact of indoor signages on customer’s buying behaviour. A comparative analysis of VM has been done at Food Bazaar (Ambala), Subhiksha (Chandigarh) and ITC Choupal Fresh (Chandigarh). Problems faced in implementation of VM at retail stores have been highlighted and some implications have been mentioned.

description: The Red-Sequence Cluster Survey (RCS) is a $\sim$100 square degree, two-filter imaging survey in the $R_C$ and $z'$ filters, designed primarily to locate and characterise galaxy clusters to redshifts as high as $z=1.4$. This paper provides a detailed description of the survey strategy and execution, including a thorough discussion of the photometric and astrometric calibration of the survey data. The data are shown to be calibrated to a typical photometric uncertainty of 0.03-0.05 magnitudes, with total astrometric uncertainties less than 0.25 arcseconds for most objects. We also provide a detailed discussion of the adaptation of a previously described cluster search algorithm (the cluster red-sequence method) to the vagaries of real survey data, with particular attention to techniques for accounting for subtle variations in survey depths caused by changes in seeing and sky brightness and transparency. A first catalog of RCS clusters is also presented, for the survey patches RCS0926+37 and RCS1327+29. These catalogs, representing about 10% of the total survey and comprising a total of 429 candidate clusters and groups, contain a total of 67 cluster candidates at a photometric redshift of $0.9

description: Indian horticulture sector is constrained by low productivity, high cost of production, huge post-harvest losses, inefficient supply chain and poor market intelligence. The present paper has brought forward two case studies of SAFAL Market and Namdhari Fresh which have been successful in over-coming the constraints that horticulture sector is facing in India for fresh fruits and vegetables. Some new marketing initiatives along with the existing supply chain inefficiencies have been highlighted to help formulate strategy and policy to achieve the much-desired second green revolution through horticulture growth.

description: The group of local unitary transformations partitions the space of n-qubit quantum states into orbits, each of which is a differentiable manifold of some dimension. We prove that all orbits of the n-qubit quantum state space have dimension greater than or equal to 3n/2 for n even and greater than or equal to (3n + 1)/2 for n odd. This lower bound on orbit dimension is sharp, since n-qubit states composed of products of singlets achieve these lowest orbit dimensions.

description: This paper assesses the roles of various factors influencing the volatility of crude oil prices and the possible linkage between this volatility and agricultural commodity markets. Stochastic volatility models are applied to weekly crude oil, corn and wheat futures prices from November 1998 to January 2009. Model parameters are estimated using Bayesian Markov chain Monte Carlo methods. The main results are as follows. Speculation, scalping, and petroleum inventories are found to be important in explaining oil price variation. Several properties of crude oil price dynamics are established including mean-reversion, a negative correlation between price and volatility, volatility clustering, and infrequent compound Poisson jumps. We find evidence of volatility spillover among crude oil, corn and wheat markets after the fall of 2006. This could be largely explained by tightened interdependence between these markets induced by ethanol production.

description: We present a study of beryllium (Be) abundances in a large sample of field solar-type dwarfs and sub-giants spanning a large range of effective temperatures. The analysis shows that Be is severely depleted for F stars, as expected by the light-element depletion models. However, we also show that Beryllium abundances decrease with decreasing temperature for stars cooler than $\sim$6000 K, a result that cannot be explained by current theoretical models including rotational mixing, but that is, at least in part, expected from the models that take into account internal wave physics. In particular, the light element abundances of the coolest and youngest stars in our sample suggest that Be, as well as lithium (Li), has already been burned early during their evolution. Furthermore, we find strong evidence for the existence of a Be-gap for solar-temperature stars. The analysis of Li and Be abundances in the sub-giants of our sample also shows the presence of one case that has still detectable amounts of Li, while Be is severely depleted. Finally, we compare the derived Be abundances with Li abundances derived using the same set of stellar parameters. This gives us the possibility to explore the temperatures for which the onset of Li and Be depletion occurs.

description: We present a numerical solution in the form of a three-dimensional (3D) vortex soliton in unmagnetized plasma in the model of the generalized Zakharov equations with saturating exponential nonlinearity. To find the solution with a high accuracy we use two-step numerical method combining the Petviashvili iteration procedure and the Newton-Kantorovich method. The vortex soliton with the topological charge $m=1$ turns out to be stable provided the nonlinear frequency shift exceeds a certain critical value. The stability predictions are verified by direct simulations of the full dynamical equation.

description: We have analysed the globular cluster (GC) system of the nucleated dwarf elliptical galaxy VCC 1087 in the Virgo cluster, based on Keck/LRIS spectroscopy and archival HST/ACS imaging. We estimate VCC 1087 hosts a total population of 77+/-19 GCs, which corresponds to a relatively high V-band specific frequency of 5.8+/-1.4. The g-z color distribution of the GCs shows a blue (metal-poor) peak with a tail of redder (metal-rich) clusters similar in color to those seen in luminous ellipticals. Spectroscopy of a subsample of 12 GCs suggests that the GC system is old and coeval (~10 Gyr), with a fairly broad metallicity distribution (-1.81. A compilation of the kinematics of the GC systems of 9 early-type galaxies shows surprising diversity in the v/sigma parameter for GC systems. In this context, the GC system of VCC 1087 exhibits the most significant rotation to velocity dispersion signature. Modeling the velocity dispersion profile of the GCs and galaxy stars suggest fairly constant mass-to-light ratios of ~3 out to 6.5 kpc. The present observations can entertain both baryonic and non-baryonic solutions, and GC velocities at larger radii would be most valuable with regard to this issue. We discuss the evolution of VCC 1087 in terms of the galaxy ``harassment'' scenario, and conclude that this galaxy may well be the remains of a faded, tidally perturbed Sc spiral [abridged].

description: Nutritional value is an important attribute of foods whose benefits can only be experienced by repetitive consumption in long run. Consumers’ knowledge about the importance and usefulness of specific nutrients in a food product may influence their subjective expectation of the product’s health benefits which in turn is translated into their perception of the product’s value. At the same time, the sensory characteristics of food products affect consumers’ immediate consumption gratification. This study makes a unique contribution to the literature by exploring the roles that nutrition knowledge and sensory evaluation play in shaping consumers’ pasture-fed beef purchasing behavior through economic experiments. Our results suggest that beef products’ sensory characteristics play a central role in determining consumers’ preferences and willingness to pay. Nutrition knowledge significantly influences consumers’ willingness to pay and different types of nutrition knowledge influence consumers’ willingness to pay in distinct ways. The significant impact of consumers’ health status on their willingness to pay is identified. The study advances the literature by providing empirical evidence of the relationship between nutrition knowledge, sensory evaluation, and consumers’ purchasing behavior observed right at the point of purchase. It can help policy makers better understand consumers’ food behavior and make initiatives to improve diet and health.

description: We argue that accidental approximate scaling symmetries are robust predictions of weakly coupled string vacua, and show that their interplay with supersymmetry and other (generalised) internal symmetries underlies the ubiquitous appearance of no-scale supergravities in low-energy 4D EFTs. We identify 4 nested types of no-scale supergravities, and show how leading quantum corrections can break scale invariance while preserving some no-scale properties (including non-supersymmetric flat directions). We use these ideas to classify corrections to the low-energy 4D supergravity action in perturbative 10D string vacua, including both bulk and brane contributions. Our prediction for the Kähler potential at any fixed order in $α'$ and string loops agrees with all extant calculations. p-form fields play two important roles: they spawn many (generalised) shift symmetries; and space-filling 4-forms teach 4D physics about higher-dimensional phenomena like flux quantisation. We argue that these robust symmetry arguments suffice to understand obstructions to finding classical de Sitter vacua, and suggest how to get around them in UV complete models.

description: The agricultural economics literature, both academic and trade, has discussed the assumed presence of cycles in livestock markets such as cattle and hogs for a very long time. Since Jarvis (1974), there has been considerable discussion over how these cycles impact optimal economic decision making. Subsequent studies such as Rucker, Burt, and LaFrance (1984), Hayes and Schmitz (1987), Foster and Burt (1992), Rosen, Murphy, and Scheinkman (1994), and Hamilton and Kastens (2000) have all investigated some aspect of how biological factors, economic events, or economic actions could be causes of and/or responses to cycles in hog and cattle inventories. There has also been debate, again both in the academic and trade literature, over the length of the cycle(s) present in hog and cattle stocks. To provide both academics and producers with accurate information on the number and periods of cycles that might be present in hog and cattle inventories, this paper provides a purely statistical view of the matter. Using over 140 years of annual data on cattle and hog inventory levels, we estimate Bayesian autoregressive, trend-stationary models on cattle inventories, hog inventories, and the growth rate of cattle inventories. We then use those models to find the posterior distributions of both the number of cycles present in each series and the period lengths of those cycles. We find multiple cycles present in all three series. Cattle inventory results show clear evidence in favor of 4.5, 6, and 11 year cycles with other cycles present but not as clearly identified. Hog inventory results identify five cycles with periods of approximately 4.5, 5.4, 6.8, 10 and 13 years. The data on the growth rate in cattle stocks has similar cycles to the series on the stock levels.

description: Metalenses offer the ground-breaking opportunity to realize highly performing low-weight, flat and ultrathin, optical elements which substantially reduce size and complexity of imaging systems. Today, a major challenge in metalenses design is still the realization of achromatic optical elements ideally focussing a broad wavelength spectrum at a single focal length. Here we present a fast and effective way to design and fabricate extremely thin all-dielectric metalenses, optimally solving achromaticity issues by means of machine learning codes. The enabling technology for fabrication is a recently developed hyper resolute two-photon direct laser writing lithography equipment. The fabricated metalenses, based on a completely flat and ultrathin design, show intriguing optical features. Overall, achromatic behavior, focal length of 1.14 mm, depth of focus of hundreds of microns and thickness of only few nanometers allow considering the design of novel and efficient imaging systems in a completely new perspective.

description: We report exact analytical expressions locating the $0\to1$, $1\to2$ and $2\to4$ bifurcation curves for a prototypical system of two linearly coupled quadratic maps. Of interest is the precise location of the parameter sets where Naimark-Sacker bifurcations occur, starting from a non-diagonal period-2 orbit. This result is the key to understand the onset of synchronization in networks of quadratic maps.

description: Maximum entropy null models of networks come in different flavors that depend on the type of constraints under which entropy is maximized. If the constraints are on degree sequences or distributions, we are dealing with configuration models. If the degree sequence is constrained exactly, the corresponding microcanonical ensemble of random graphs with a given degree sequence is the configuration model per se. If the degree sequence is constrained only on average, the corresponding grand-canonical ensemble of random graphs with a given expected degree sequence is the soft configuration model. If the degree sequence is not fixed at all but randomly drawn from a fixed distribution, the corresponding hypercanonical ensemble of random graphs with a given degree distribution is the hypersoft configuration model, a more adequate description of dynamic real-world networks in which degree sequences are never fixed but degree distributions often stay stable. Here, we introduce the hypersoft configuration model of weighted networks. The main contribution is a particular version of the model with power-law degree and strength distributions, and superlinear scaling of strengths with degrees, mimicking the properties of some real-world networks. As a byproduct, we generalize the notions of sparse graphons and their entropy to weighted networks.

Coexistence of ferromagnetism and superconductivity near quantum phase transition: The Heisenberg- to Ising-type crossover

description: A microscopic mean-field theory of the phase coexistence between ferromagnetism and superconductivity in the weakly ferromagnetic itinerant electron system is constructed, while incorporating a realistic mechanism for superconducting pairing due to the exchange of critical spin fluctuations. The self-consistent solution of the resulting equations determines the superconducting transition temperature which is shown to depend strongly on the exchange splitting. The effect of phase crossover from isotropic (Heisenberg-like) to uniaxial (Ising-like) spin fluctuations near the quantum phase transition is analysed and the generic phase diagram is obtained. This scenario is then applied to the case of itinerant ferromagnet ZrZn2, which sheds light on the proposed phase diagram of this compound. Possible explanation of superconductivity in UGe2 is also discussed.

description: The issuance of weak patents is widely viewed as a fundamental problem in the current US patent system. Reasons that have been offered for the granting of weak patents by the US Patent and Trademark Office (USPTO) include examiners’ “rational ignorance” of the patentability of applications and pro-“customer” rules and institutions that create incentives for examiners to grant patents of dubious validity to their “customers”- applicants. In this paper, we study whether US examiners’ behavior in prior art search betrays their assessment of applications’ patentability. For a sample of US patents for which applications were also filed at the European Patent Office (EPO), we construct a measure of the fraction of prior art that is missed by US examiners. We find that this measure significantly explains the probability of receiving a patent at the EPO. The results are robust to different empirical specifications. US examiners’ prior art searches indicate that they are, on average, not “rationally ignorant”. On the contrary, they identify and dedicate more search effort to those applications that seem more problematic, because they bear the burden of proof of non-patentability. Our study offers empirical evidence that a systematic problem of weak patents likely exists, and suggests that the problem may be more strongly attributable to the pro-applicant rules and policies than to examiners’ ignorance. The current prevalence of weak patents does not appear to be caused at the margin by lack of resources at the USPTO.
Biodegradation and environmental impact of lipid-rich wastes under aerobic composting conditions
Creators: name: Lemus, Gladis R.
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this research was to evaluate the 'compostability' of organic wastes rich in lipids, such as canola oil and grease trap sludge, when added to yard trimmings or food wastes. This study was divided in three parts: composting process performance, environmental impact, and compost quality. In addition, a composting simulation model was developed in this study. Aerobic biodegradation of yard trimmings and food waste loaded with lipidic compounds, up to 35% dry solids (ds) for the canola oil tests, and up to 10% ds for grease trap sludge, produced satisfactory results in terms of temperature profile, lipids and volatile solids reduction, wet mass consumption, and moisture content removal. For the high rate phase of composting, treatments with either canola oil or grease trap sludge added resulted in biodegradation rate values for volatile solids (kvs) of 0.009- 0.039 day"1. In contrast, yard trimmings alone had a kv sof 0.033 day"1 and food waste alone had a kv sof 0.023 day-1. For treatments with yard trimmings as main substrate, the addition of 5% ds grease trap sludge had similar air emission as yard trimmings alone. The addition of 10% ds grease trap sludge to yard trimmings resulted in more nitrous oxide and carbon dioxide, less ammonia, and similar odor emissions, when compared with the emissions of yard trimmings alone. As for the phytotoxic potential, treatments with 10% ds grease trap sludge added (to food waste or yard trimmings) resulted in germination indexes similar to the treatment with distilled water alone, but their values were significantly smaller than the values for the treatments with 5% ds or no lipid added. A 'macrokinetic' model was developed using a dynamic modeling approach (mass and energy balances with kinetic parameters) for the simulation of the composting process. The model allowed for the inclusion of lipid wastes as an energy amendment, while including provisions for temperature control through aeration. These produced satisfactory results in terms of thermal parameters simulation. As a practical recommendation, yard trimmings composting with grease trap sludge added at 5% ds would result in enhanced thermal performance, improved rate and extent of biodegradation of solids and lipids, and greater overall reduction in wet mass and water content, when compared with the composting of yard trimmings alone.

description: The 2006 spike in corn-based ethanol demand has contributed to the increase in basis volatility in corn and soybean markets across the United States, which has, to a significant degree, led to the observed large jumps in the prices of the two commodities. Despite the overall rise in basis volatility, there remain differences in the degree of volatility that exists across spatially separated markets, which might be caused by factors such as transportation costs, seasonality, and time-to-delivery. The focus of this study is threefold first, this work models basis data for six corn and soybean markets by using a multivariate GARCH model that incorporates the spatial linkages of these markets; next, the model is used to investigate whether the increase in ethanol demand has significantly aided in the rise of basis volatilities; and last, the spatio-temporal linkages among basis volatilities in different markets are examined under various scenarios of spot-price shocks.

description: A big part of the video content we consume from video providers consists of genres featuring low-light aesthetics. Low light sequences have special characteristics, such as spatio-temporal varying acquisition noise and light flickering, that make the encoding process challenging. To deal with the spatio-temporal incoherent noise, higher bitrates are used to achieve high objective quality. Additionally, the quality assessment metrics and methods have not been designed, trained or tested for this type of content. This has inspired us to trigger research in that area and propose a Grand Challenge on encoding low-light video sequences. In this paper, we present an overview of the proposed challenge, and test state-of-the-art methods that will be part of the benchmark methods at the stage of the participants' deliverable assessment. From this exploration, our results show that VVC already achieves a high performance compared to simply denoising the video source prior to encoding. Moreover, the quality of the video streams can be further improved by employing a post-processing image enhancement method.

description: Model-independent observables to pick out the Abelian Z' signal in the Bhabha process are introduced at energies >= 200 GeV. They measure separately the Z'-induced vector and axial-vector four-fermion contact couplings. The analysis of the LEP2 data constrains the value of the Z'-induced vector four-fermion coupling at the 2-sigma confidence level that corresponds to the Abelian Z' boson with the mass of order 1 TeV.
