description: Simulations predict that the first stars in an LCDM universe formed at redshifts z>20 in minihalos with masses of about 10^6 M_sun. We have studied their radiative feedback by simulating the propagation of ionization fronts (I-fronts) created by these first Population III stars (M_* = 15-500 M_sun) at z=20, within the density field of a cosmological simulation of primordial star formation, outward thru the host minihalo and into the surrounding gas. A three-dimensional ray-tracing calculation tracks the I-front once the H II region evolves a "champagne flow'' inside the minihalo, after the early D-type I-front detaches from the shock and runs ahead, becoming R-type. We take account of the hydrodynamical back-reaction by an approximate model of the central wind. We find that the escape fraction of ionizing radiation from the host halo increases with stellar mass, with 0.7 < f_esc <0.9 for 80 < M_*/M_sun < 500. To quantify the ionizing efficiency of these stars as they begin cosmic reionization, we find that, for M_* > 80 M_sun, the ratio of gas mass ionized to stellar mass is ~60,000, roughly half the number of ionizing photons released per stellar baryon. Nearby minihalos are shown to trap the I-front, so their centers remain neutral. This is contrary to the recent suggestion that these stars would trigger formation of a second generation by fully ionizing neighboring minihalos, stimulating H_2 formation in their cores. Finally, we discuss how the evacuation of gas from the host halo reduces the growth and luminosity of "miniquasars'' that may form from black hole remnants of the first stars.

description: We demonstrate the possibility to create optical beams with phase singularities engraved into exotic intensity landscapes imitating the shapes of a large variety of diverse plane curves. To achieve this aim, we have developed a method for directly encoding the geometric properties of some selected curve into a single azimuthal phase factor without passing through indirect encryption methods based on lengthy numerical procedures. The outcome is utilized to mould the optic axis distribution of a liquid-crystal-based inhomogeneous waveplate. The latter is finally used to sculpt the wavefront of an input optical gaussian beam via Pancharatnam-Berry phase.

description: The linear inverse problem is fundamental to the development of various scientific areas. Innumerable attempts have been carried out to solve different variants of the linear inverse problem in different applications. Nowadays, the rapid development of deep learning provides a fresh perspective for solving the linear inverse problem, which has various well-designed network architectures results in state-of-the-art performance in many applications. In this paper, we present a comprehensive survey of the recent progress in the development of deep learning for solving various linear inverse problems. We review how deep learning methods are used in solving different linear inverse problems, and explore the structured neural network architectures that incorporate knowledge used in traditional methods. Furthermore, we identify open challenges and potential future directions along this research line.

description: We study theoretically the entropic elasticity of a semi-flexible polymer, such as DNA, confined to two dimensions. Using the worm-like-chain model we obtain an exact analytical expression for the partition function of the polymer pulled at one end with a constant force. The force-extension relation for the polymer is computed in the long chain limit in terms of Mathieu characteristic functions. We also present applications to the interaction between a semi-flexible polymer and a nematic field, and derive the nematic order parameter and average extension of the polymer in a strong field.

description: The planning of a policy intervention aims at optimizing the decision-making process, resources allocation, outcomes of the intervention. The development of an integrated approach may contribute to achieve an effective and efficient planning. The article develops a protocol based on the adoption of qualitative and quantitative methods, in order to support policymaker in planning intervention measures. The developed protocol is tested on a case study: the planning of measure 14 – Animal welfare – in the Rural Development Programme 2014-2020 of the Apulia region. Indicators of animal welfare, scientifically valid and objectively miserable, emerged from the case study as additional commitments to implement in cattle and buffalo farms. An economic analysis of each indicators allowed to estimate a countervailing measure for additional costs associated with the achievement of higher standards of animal welfare.

Innovation in the Italian Sector of Vending Machines. Between Growth and Search for Sustainability

Year: 2020

description: Changes in lifestyles involve many aspects of food consumption widely analysed in literature, while the development of specific distribution forms, such as the vending machines, are less known and still perceived unsuitable to respond to the segmentation of demand. This sector is recording impressive growth rates. Italy is the country in Europe with the highest number of machines, as well as being leader in the production of machines and in the development of management services. This growth is not extraneous to the search for greater qualification of the foodstuff supply. The most recent data show numerous experiences aimed at introducing a more accurate selection of products supplied. Nevertheless, the agricultural sector doesn’t seem to be adequately involved in the vending machines supply chain, except for some limited experiences. The objective of the paper is to analyse the most significant initiatives to assess whether they could contribute to the reinforcement of the role of agriculture and to the definition of new criteria within the selection procedures for vending services.

A Near-Infrared Analysis of the Submillimeter Background and the Cosmic Star-Formation History

description: We use new deep near-infrared (NIR) and mid-infrared (MIR) observations to analyze the 850$~μ$m image of the GOODS HDF-N region. We show that much of the submillimeter background at this wavelength is picked out by sources with $H(AB)$ or 3.6um (AB)<23.25 (1.8 uJy). These sources contribute an 850um background of 24\pm2 Jy deg^-2. This is a much higher fraction of the measured background (31-45 Jy deg^-2) than is found with current 20cm or 24um samples. Roughly one-half of these NIR-selected sources have spectroscopic identifications, and we can assign robust photometric redshifts to nearly all of the remaining sources using their UV to MIR spectral energy distributions. We use the redshift and spectral type information to show that a large fraction of the 850um background light comes from sources with z=0-1.5 and that the sources responsible have intermediate spectral types. Neither the elliptical galaxies, which have no star formation, nor the bluest galaxies, which have little dust, contribute a significant amount of 850um light, despite the fact that together they comprise approximately half of the galaxies in the sample. The galaxies with intermediate spectral types have a mean flux of 0.40\pm0.03 mJy at 850um and 9.1\pm0.3 uJy at 20cm. The redshift distribution of the NIR-selected 850um light lies well below that of the much smaller amount of light traced by the more luminous, radio- selected submillimeter sources. We therefore require a revised star-formation history with a lower star-formation rate at high redshifts. We use a stacking analysis of the 20cm light in the NIR sample to show that the star-formation history of the total 850um sample is relatively flat down to z~1 and that half of the total star formation occurs at redshifts z<1.4.
description: 14 pages, 15 figures. Accepted by The Astrophysical Journal for v647n 1 issue, August 2006. Minor changes in response to the referee's report, plus a new comparison figure of the star formation history measured in the FIR with that measured in the UV. We plot d(rho)/dt x cosmic time vs. cosmic time, which has the advantage of illustrating more directly how many stars are formed at a given time
Determination of A_{FB}^b at the Z pole using inclusive charge reconstruction and lifetime tagging

Year: 2004

description: A novel high precision method measures the b-quark forward-backward asymmetry at the Z pole on a sample of 3,560,890 hadronic events collected with the DELPHI detector in 1992 to 2000. An enhanced impact parameter tag provides a high purity b sample. For event hemispheres with a reconstructed secondary vertex the charge of the corresponding quark or anti-quark is determined using a neural network which combines in an optimal way the full available charge information from the vertex charge, the jet charge and from identified leptons and hadrons. The probability of correctly identifying b-quarks and anti-quarks is measured on the data themselves comparing the rates of double hemisphere tagged like-sign and unlike-sign events. The b-quark forward-backward asymmetry is determined from the differential asymmetry, taking small corrections due to hemisphere correlations and background contributions into account. The results for different centre-of-mass energies are: A_{FB}^b (89.449 GeV) = 0.0637 \pm 0.0143(stat.) \pm 0.0017(syst.) A_{FB}^b (91.231 GeV) = 0.0958 \pm 0.0032(stat.) \pm 0.0014(syst.) A_{FB}^b (92.990 GeV) = 0.1041 \pm 0.0115(stat.) \pm 0.0024(syst.) Combining these results yields the b-quark pole asymmetry A_{FB}^{b,0} = 0.0972 \pm 0.0030(stat.) \pm 0.0014(syst.)

description: The orbital period of the hot Jupiter WASP-4b appears to be decreasing at a rate of $-8.64 \pm 1.26$ msec/yr, based on transit-timing measurements spanning 12 years. Proposed explanations for the period change include tidal orbital decay, apsidal precession, and acceleration of the system along the line of sight. To investigate further, we performed new radial velocity measurements and speckle imaging of WASP-4. The radial-velocity data show that the system is accelerating towards the Sun at a rate of $-0.0422\pm 0.0028$ m/s/day. The associated Doppler effect should cause the apparent period to shrink at a rate of $-5.94 \pm 0.39$ msec/yr, comparable to the observed rate. Thus, the observed change in the transit period is mostly or entirely produced by the line-of-sight acceleration of the system. This acceleration is probably caused by a wide-orbiting companion of mass 10-300$\,M_{\rm Jup}$ and orbital distance 10-100$\,$AU, based on the magnitude of the radial-velocity trend and the non-detection of any companion in the speckle images. We expect that the orbital periods of 1 out of 3 hot Jupiters will change at rates similar to WASP-4b, based on the hot-Jupiter companion statistics of Knutson et al. (2014). Continued radial velocity monitoring of hot Jupiters is therefore essential to distinguish the effects of tidal orbital decay or apsidal precession from line-of-sight acceleration.

description: A deep mid- and far-infrared survey in the Extended Groth Strip (EGS) area gives 3.6 to 8\micron flux densities or upper limits for 253 Lyman Break Galaxies (LBGs). The LBGs are a diverse population but with properties correlated with luminosity. The LBGs show a factor of 30 range in indicated stellar mass and a factor of 10 in apparent dust content relative to stellar mass. About 5% of LBGs are luminous at all wavelengths with powerful emission at rest 6\micron. In the rest 0.9 to 2\micron spectral range these galaxies have stellar spectral slopes with no sign of an AGN power law component, suggesting that their emission is mainly powered by intensive star formation. Galaxies in this luminous population share the infrared properties of cold SCUBA sources: both are massive and dusty starburst galaxies at $2

Exploration of the role of the community response network in Kelowna
Creators: name: Bird, Marie Christine
Publisher: name: University of British Columbia
Year: 2009

description: The Community Response Network in Kelowna was formed from the policydriven elder abuse committee and as a response to the Adult Guardianship Act of British Columbia enacted in 2000. After the inception of the act that addresses abuse, neglect and self-neglect of adults, the Community Response Network - a community development initiative that was implemented from social policy - was unsure of its role in the community. The purpose of this qualitative research is to assist the network in defining its role in supporting adults who may be vulnerable to harm. What is the role of the Community Response Network? What did the network do in the past? How effective was it? Who should be involved? It was thought that the network would continue to offer education and awareness to community members. Through a purposeful convenience sample of participants in both a focus group and individual interviews, various themes such as structure, values, context and tasks were evident through verbatim analysis. As well, through a feminist analysis, several dichotomies and inconsistencies were interpreted. Recommendations for the network include continuing education and awareness workshops, strengthening linkages in the community, and inviting a diverse group of people to become involved in the committee.

description: Since the discovery of the high-T$_{c}$ cuprate superconductor La$_{2-x}$BaCuO$_{4}$ in 1986 by Bednorz and Müller, controversy regarding the nature or origin of this remarkable superconductivity has continued. However, d-wave superconductivity in the hole-doped cuprates, arising due to the anti-paramagnon exchange, was established around 1994. More recently we have shown that the mean field theory, like the BCS theory of superconductivity and Landau's Fermi liquid theory are adequate to describe the cuprates. The keys for this development are the facts that a)the pseudogap phase is d-wave density wave (dDW) and that the high-T$_{c}$ cuprate superconductivity is gossamer (i.e. it exists in the presence of dDW).

description: Magnetic fields can give rise to a plethora of phenomena in Kitaev spin systems, such as the formation of non-trivial spin liquids in two and three spatial dimensions. For the original honeycomb Kitaev model, it has recently been observed that the sign of the bond-directional exchange is of crucial relevance for the field-induced physics, with antiferromagnetic couplings giving rise to an intermediate spin liquid regime between the low-field gapped Kitaev spin liquid and the high-field polarized state, which is not present in the ferromagnetically coupled model. Here, by employing a Majorana mean-field approach for a magnetic field pointing along the [001] direction, we present a systematic study of field-induced spin liquid phases for a variety of two and three-dimensional lattice geometries. We find that antiferromagnetic couplings generically lead to (i) spin liquid phases that are considerably more stable in field than those for ferromagnetic couplings, and (ii) an intermediate spin liquid phase which arises from a change in the topology of the Majorana band structure. Close inspection of the mean-field parameters reveal that the intermediate phase occurs due to a field-driven sign change in an 'effective' $z$-bond energy parameter. Our results clearly demonstrate the richness of the Majorana physics of the antiferromagnetic Kitaev models, in comparison to their ferromagnetic counterparts.

We use fully self consistent numerical methods to compute the condensation free energies of the possible order parameter configurations as a function of temperature $T$. As $T$ varies, we find that there are phase transitions between states characterized by different junction configurations (denoted as ``0'' or ``$π$'' according to the phase difference of the order parameter in consecutive S layers). We show that these transitions are of first order. We calculate the associated latent heats and find them to be measurable.

description: Theory of magneto-oscillation phenomena has been developed for two-dimensional electron systems with linear-in-k spin splitting. Both Dresselhaus and Rashba contributions are taken into account. It has been shown that the pattern of the magneto-oscillations depends drastically on the ratio between the above terms. The presence of only one type of the k-linear terms gives rise to the beats, i.e. two close harmonics corresponding to the spin-split subbands. However, if the strengths of both contributions are comparable, the third (central) harmonics appears in the spectrum of the magneto-oscillations. For equal strengths of the contributions, only the central harmonic survives, and the oscillations occur at a single frequency, although the k-linear terms remain in the Hamiltonian. Such suppression of the spin beats is studied in detail by the example of the Shubnikov-de Haas effect.

description: We use time-resolved Faraday rotation to measure coherent spin dynamics in colloidal CdSe quantum dots charged in an electrochemical cell at room temperature. Filling of the 1Se electron level is demonstrated by the bleaching of the 1Se-1S3/2 absorption peak. One of the two Lande g-factors observed in uncharged quantum dots disappears upon filling of the 1Se electron state. The transverse spin coherence time, which is over 1 ns and is limited by inhomogeneous dephasing, also appears to increase with charging voltage. The amplitude of the spin precession signal peaks near the half-filling potential. Its evolution at charging potentials without any observable bleaching of the 1Se-1S3/2 transition suggests that the spin dynamics are influenced by low-energy surface states.

These are the most widely known and used of the various formulas and equations of both types, but there had been no previous comprehensive study of their validity under commercial conditions. A secondary purpose was to obtain data on the average solids-not-fat content of milk in some important dairy areas in the United States.

description: Plant breeding is one of the key strategies for further enhancement of crop yields; however, effective breeding strategies require phenotypic characterisation of the available germplasm. This study sought to characterise the phenotypic expression of fourteen crop traits related to phenology, plant architecture, and yield in a panel of 40 cultivars selected to represent the phenotypic variability present in Italian rice germplasm during a two-season field experiment. The observed range of phenotypic variation was high for many traits (coefficients of variation ranging from 5.9\% to 45.4\%) including yield (mean: 6.47 t ha\textsuperscript{-1}; CV: 15.4\%; min: 2.19 t ha\textsuperscript{-1}; max: 8.95 t ha\textsuperscript{-1}), and multiple strong associations emerged in all the analysed traits. Cluster analysis extracted three groups of genotypes characterised by alternative yield strategies, i.e. "high-tillering", "early maturing", and "increased source-sink". Our findings highlight that rice yield decrease when one strategy is overemphasised. In contrast, the highest-yielding genotypes have a balanced ratio between sink and source organs, along with a proportional duration of vegetative and reproductive phases. This study depicts the phenotypic variability in Italian rice cultivars and proposes a novel classification based on yield-related traits which could be of use in multiple rice breeding applications.

description: We obtain general predictions for the distribution of wave function intensities in position space on the periodic orbits of chaotic ballistic systems. The expressions depend on effective system size N, instability exponent lambda of the periodic orbit, and proximity to a focal point of the orbit. Limiting expressions are obtained that include the asymptotic probability distribution of rare high-intensity events and a perturbative formula valid in the limit of weak scarring. For finite system sizes, a single scaling variable lambda N describes deviations from the semiclassical N -> infinity limit.

description: We discuss recent developments in the modeling of negative autoregulated genetic networks. In particular, we consider the temporal evolution of the population of mRNA and proteins in simple networks using rate equations. In the limit of low copy numbers, fluctuation effects become significant and more adequate modeling is then achieved using the master equation formalism. The analogy between regulatory gene networks and chemical reaction networks on dust grains in the interstellar medium is discussed. The analysis and simulation of complex reaction networks are also considered.

Updated predictions for gravitational waves produced in a strongly supercooled phase transition

description: We update predictions for the gravitational wave (GW) signal from a strongly supercooled phase transition in an illustrative classically conformal U(1)$_{B-L}$ model. We implement $\propto γ^2$ scaling of the friction on the bubble wall and update the estimates for the efficiency factors for GW production from bubble collisions and plasma-related sources. We take into account the fact that a small decay rate of the symmetry-breaking field may lead to brief matter-dominated era after the transition, as the field oscillates around its minimum before decaying. We find that a strong bubble collision signal occurs in a significant part of the parameter space, and that the modified redshift of the modes that re-enter the horizon during the matter-dominated period generates a characteristic tilted `plateau' in the spectrum. The GW spectrum in this model would be detectable in the low-frequency range, e.g., by LISA, and in the mid-frequency range, e.g., by AION/MAGIS and AEDGE, and in the high-frequency range by LIGO and ET. The peak frequency of the signal is limited from below by collider constraints on the mass of the U(1)$_{B-L}$ gauge boson, while at high frequencies the slow decay of the scalar field and the resulting matter-dominated era diminishes the GW signal.

Characterization of gene expression patterns in the developing natural killer cell
Creators: name: Birro, Natasha Diane
Publisher: name: University of British Columbia
Year: 2009

description: Relatively little is known about development of the Natural Killer (NK) cell. Studies in the past have focused on characterizing the phenotype of the NK cell, and evaluating its development by manipulating hematopoietic stem cells in vitro. When I began my study, an in vitro culture system had been recently developed in my laboratory in which embryonic stem cells are induced with various cytokines and growth factors to differentiate into NK cells. This system provides a medium where NK cell development can be researched from an earlier stage than previously possible. The objective of my work was to use this culture system to investigate the expression patterns of five genes which are known to play a role in lymphoid cell development based on gene knock-out studies. Id-2 is an inhibitor of DNA binding protein, Ikaros-1 and Ets-1 are transcription factors, Notch-1 is a transmembrane receptor and Jagged-1 is a ligand for Notch. Using RT-PCR and phospho-image analysis, the expression patterns of these genes were assessed from various numbers of cells, and at five different points along the developmental pathway of the NK cell. Id-2 seemed to be expressed consistently throughout the system. Ikaros-1 and Ets-1 were interesting in that they showed an on/off expression pattern, Ets-1 with little expression on days 8 and 14, and Ikaros-1 with no expression on days 8 and 14. This implies that perhaps these transcription factors are not needed at the initial stage of NK cell differentiation from a common lymphoid precursor. Notch-1 and Jagged-1 were particularly interesting in that their expression patterns did not parallel each other. These results suggest that Jagged-1 may not be the ligand of choice for proper NK cell development as Notch levels were lower than expected. These studies have begun to give us a better understanding of gene expression in our system, and provide clues as to what role certain gene may play.

description: The evolution of vertical coordination systems and pricing mechanisms in the Russian food system are summarized. The activities in the stages of the food vertical chain during the command economy period were coordinated administratively similar to an integrated firm. Coordination in the food chain has evolved from mostly vertical expansion through quasi integration to mostly vertical mergers, as the Russian economy has started to move toward a more market oriented system. The unique characteristics of the exchange system and the structural nature of agriculture in the potential importing country are important considerations to take into account by exporting agribusiness firms.
An Entropy Equation for Energy

Subjects: subject: Artificial Intelligence (cs.AI)

subject: FOS: Computer and information sciences

description: This paper describes an entropy equation, but one that should be used for measuring energy and not information. In relation to the human brain therefore, both of these quantities can be used to represent the stored information. The human brain makes use of energy efficiency to form its structures, which is likely to be linked to the neuron wiring. This energy efficiency can also be used as the basis for a clustering algorithm, which is described in a different paper. This paper is more of a discussion about global properties, where the rules used for the clustering algorithm can also create the entropy equation E = (mean * variance). This states that work is done through the energy released by the 'change' in entropy. The equation is so simplistic and generic that it can offer arguments for completely different domains, where the journey ends with a discussion about global energy properties in physics and beyond. A comparison with Einstein's relativity equation is made and also the audacious suggestion that a black hole has zero-energy inside.

description: Using a linear programming model, this study evaluates the effects of commercializing new biotech-soybean varieties on the livestock producers' feed costs and formulations. Major findings include: (1) development of new alternative soybeans would benefit poultry meat producers more than egg and pig meat producers; (2) new soybean meals would save more feed costs in starter diets than in either grower or finisher diets; and (3) economic advantages of new soybean meals were highly sensitive to the availability of alternative protein sources but less sensitive to changes in ingredient prices.

FRB Coherent Emission from Decay of Alfven Waves

Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present a model for FRBs where a large amplitude Alfven wave packet is launched by a disturbance near the surface of a magnetar, and a substantial fraction of the wave energy is converted to coherent radio waves at a distance of a few tens of neutron star radii. The wave amplitude at the magnetar surface should be about 1011G in order to produce a FRB of isotropic luminosity 10$^{44}$ erg s$^{-1}$. An electric current along the static magnetic field is required by Alfven waves with nonzero component of transverse wave-vector. The current is supplied by counter-streaming electron-positron pairs, which have to move at nearly the speed of light at larger radii as the plasma density decreases with distance from the magnetar surface. The counter-streaming pairs are subject to two-stream instability which leads to the formation of particle bunches of size of order $c/ω_p$; where $ω_p$ is plasma frequency. A strong electric field develops along the static magnetic field when the wave packet arrives at a radius where electron-positron density is insufficient to supply the current required by the wave. The electric field accelerates particle bunches along the curved magnetic field lines, and that produces the coherent FRB radiation. We provide a number of predictions of this model.

description: Case study research is increasingly important in agricultural economics as a means of collecting data, and building and testing theory. Case study research has a prescribed set of objectives, epistemology, methodology, and methods that have been developed and tested in a wide range of scholarly and problem-solving situations. This article reviews these fundamentals and then demonstrates the case study approach within the context of an agribusiness research project. This application exemplifies how case study research is capable of generating a robust, comprehensive array of "knowledge" about complex, highly interdependent and dynamic economic and social phenomena.
