description: Based on the introduction of the natural and geographic conditions in Bayingolin Mongol Autonomous Prefecture in Xinjiang(Bazhou), development status of Korla Fragrant Pear is introduced from the two aspects of the production status and the storage and processing status of Korla Fragrant Pear. Among them, production status of Korla Fragrant Pear is analyzed from the aspects of the rapid growth of planting area and the stable growth of output. And the storage and processing status of Korla Fragrant Pear is introduced from the aspects of the development status of the storage industry and the development status of processing industry, and the status of domestic and foreign marketing. Problems in the industrialization development of Korla Fragrant Pear in Bazhou are analyzed, such as the weak protection of brand and lack of external propaganda, the imperfect benefit affiliating mechanism between leading enterprises and peasant households, and the marketing network of Korla Fragrant Pear and single mode of marketing. Countermeasures for the acceleration of the industrial development of Korla Fragrant Pear in Bazhou are put forward, such as making great efforts at publicity, brand establishment and counterfeit prevention, cultivating leading enterprises, reducing market risk, implementing industrialization development, adopting various marketing forms and actively developing domestic and international markets.

description: This paper describes the observations and data reduction techniques for the version 2.0 images and catalog of the NICMOS Ultra Deep Field Treasury program. All sources discussed in this paper are based on detections in the combined NICMOS F110W and F160W bands only. The NICMOS images are drizzled to 0.09 arc second pixels and aligned to the ACS UDF F850LP image which was rebinned to the same pixel scale. These form the NICMOS version 2.0 UDF images. The catalog sources are chosen with a conservative detection limit to avoid the inclusion of numerous spurious sources. The catalog contains 1293 objects in the 144 x 144 arc sececonds NICMOS subfield of the UDF. The 5 sigma signal to noise level is an average 0.6 arc second diameter aperture AB magnitude of ~27.7 at 1.1 and 1.6 microns. The catalog sources, listed in order of right ascension, satisfy a minimum signal to noise criterion of 1.4 sigma in at least 7 contiguous pixels of the combined F110W and F160W image

description: This thesis gives the overview of concept and constitution of the closed supply chain of green agricultural products on logistics center, and the necessity of regarding logistics center as core enterprises. Meanwhile, it analyzes the function of logistic center of agricultural products, namely functions of exchange, collection, distribution, storage and transportation. It also poses the prerequisites of logistics center. The logistics center of agricultural products must have stable profit expectancy, prominent scale, strong appealing power, capacity of bearing market risk and basic thoughts of supply chain management. The functional design of the closed supply chain of green agricultural products has been discussed in 5 aspects, namely logistics center, production base, provides for means of production, retailer and consumer. The operating thoughts of the closed supply chain of green agricultural products based on logistics center are put forward on the basis of the research of operating objective and service target of supply chain as follows: first, based on local principal agricultural products, the logistics center mainly distributes the massed agricultural products; second, it is necessary to choose appropriate strategic cooperative partners to sign contract; third, the operating procedures of supply chain entails bringing in professional managerial talents of supply chain; finally, the relationships of supply chain should be maintained.

description: Measurements by the Belle Collaboration of the cross section for inclusive J/psi production in e^+e^- annihilation have been a serious challenge to current heavy-quarkonium theory. Especially, the measured cross sections for exclusive J/psi+eta_c and inclusive J/psi+cc-bar+X differ from nonrelativistic QCD predictions by an order of magnitude. In order to check if other available alternative theory can resolve such a large discrepancy, we calculate the cross section for inclusive J/psi+cc-bar+X based on the color-evaporation model. As a phenomenological model, the color-evaporation model is still employed to predict cross sections for inclusive quarkonium production in various processes. Our results show that the color-evaporation-model prediction is even smaller than the nonrelativistic QCD prediction by an order of magnitude. The resultant color-evaporation-model prediction for J/psi+cc-bar+X fraction in the inclusive J/psi production cross section is 0.049, while the empirical value measured by the Belle Collaboration is 0.82.

description: Canola has become an important crop in the last decade in the U.S. Production of canola is risky and competes with other crops which have a range of risk reduction mechanisms. Alternative contracting strategies were evaluated by comparing returns to labor and management for growers and gross margins for processors. Alternative contracting strategies included no contract, fixed price with and without act of god provisions, and an oil premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function. We estimated certainty equivalents and ranked contract preferences for both growers and processors by region in North Dakota. Grower and processor risk preferences varied by region. Producers and processors preferences differed for contract alternatives in the Northwest, Northeast and Eastcentral regions and were in agreement in the Northcentral region. This suggests that development of a single contract that would be widely adopted across the state would likely have to be altered by region to be acceptable to growers and processors.

description: Submillimetre-selected galaxies (SMGs) at high redshift ($z$ $\sim$ 2) are potential host galaxies of active galactic nuclei (AGN). If the local Universe is a good guide, $\sim$ 50$\%$ of the obscured AGN amongst the SMG population could be missed even in the deepest X-ray surveys. Radio observations are insensitive to obscuration; therefore, very long baseline interferometry (VLBI) can be used as a tool to identify AGN in obscured systems. A well-established upper limit to the brightness temperature of 10$^5$ K exists in star-forming systems, thus VLBI observations can distinguish AGN from star-forming systems via brightness temperature measurements. We present 1.6 GHz European VLBI Network (EVN) observations of four SMGs (with measured redshifts) to search for evidence of compact radio components associated with AGN cores. For two of the sources, e-MERLIN images are also presented. Out of the four SMGs observed, we detect one source, J123555.14, that has an integrated EVN flux density of 201 $\pm$ 15.2 $μ$Jy, corresponding to a brightness temperature of 5.2 $\pm$ 0.7 $\times$ 10$^5$ K. We therefore identify that the radio emission from J123555.14 is associated with an AGN. We do not detect compact radio emission from a possible AGN in the remaining sources (J123600.10, J131225.73, and J163650.43). In the case of J131225.73, this is particularly surprising, and the data suggest that this may be an extended, jet-dominated AGN that is resolved by VLBI. Since the morphology of the faint radio source population is still largely unknown at these scales, it is possible that with a $\sim$ 10 mas resolution, VLBI misses (or resolves) many radio AGN extended on kiloparsec scales.

description: Liquid-liquid and liquid-vapor coexistence regions of various water models were determined by MC simulations of isotherms of density fluctuation restricted systems and by Gibbs ensemble MC simulations. All studied water models show multiple liquid-liquid phase transitions in the supercooled region: we observe two transitions of the TIP4P, TIP5P and SPCE model and three transitions of the ST2 model. The location of these phase transitions with respect to the liquid-vapor coexistence curve and the glass temperature is highly sensitive to the water model and its implementation. We suggest, that the apparent thermodynamic singularity of real liquid water in the supercooled region at about 228 K is caused by an approach to the spinodal of the first (lowest density) liquid-liquid phase transition. The well known density maximum of liquid water at 277 K is related to the second liquid-liquid phase transition, which is located at positive pressures with a critical point close to the maximum. A possible order parameter and the universality class of liquid-liquid phase transitions in one-component fluids is discussed.

description: The Baillie-PSW primality test combines Fermat and Lucas probable prime tests. It reports that a number is either composite or probably prime. No odd composite integer has been reported to pass this combination of primality tests if the parameters are chosen in an appropriate way. Here, we describe a significant strengthening of this test that comes at almost no additional computational cost. This is achieved by including in the test what we call Lucas-V pseudoprimes, of which there are only five less than $10^{15}$.

Odmas : object discovery through motion, appearance and shape
Creators: name: Southey, Tristram
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis we examine the problem of Object Discovery, the autonomous acquisition of object models, using a combination of shape, appearance and motion. We propose a new technique for detecting rigidly moving objects and constructing models of their appearance and shape called the ODMAS (Object .Discovery through Motion, Appearance and Shape) system. Our technique is a multi-stage approach. First, a stereo camera is used to find a sequence of images and shape maps of a given scene. Then the scene is oversegmented using normalized cuts based on a combination of shape and appearance. SIFT image features are matched between sequential pairs of images to identify groups of moving features and the three dimensional location of these moving features in the scene is identified using the shape map from the stereo camera. The moving features are then further individuated into objects by identifying groups where the motion of the features is rigid. These rigid feature groups are used to determine which regions in the segmentation of the scene correspond to objects, grouping together oversegmented regions as necessary. Additional features are extracted from these regions and combined with the rigidly moving image features to create snapshots of the object's appearance and shape. Finally, these snapshots are grouped together over time to produce models of the objects.

description: Long time scale radio-X-ray correlations in black holes during the hard state have been found in many sources and there seems to emerge a universal underlying relationship which quantitatively describes this behavior. Although it would appear only natural to detect short term emission patterns in the X-ray and - with a certain time lag - in the radio, there has been little evidence for this up to now. The most prominent source for radio-X-ray correlations on short time scales (minutes) so far remains GRS 1915+105 where a single mass ejection could be detected successively in the X-ray, IR, and radio wavebands. We analyze a database of more than 4 years of simultaneous radio-X-ray data for Cygnus X-1 from the Ryle Telescope and RXTE PCA/HEXTE. We confirm the existence of a radio-X-ray correlation on long time scales, especially at hard energies. We show that apparent correlations on short time scales in the lightcurves of Cygnus X-1 are most likely the coincidental outcome of white noise statistics. Interpreting this result as a breakdown of radio-X-ray correlations on shorter time scales, this sets a limit to the speed of the jet.

description: The de novo design of molecular structures using deep learning generative models introduces an encouraging solution to drug discovery in the face of the continuously increased cost of new drug development. From the generation of original texts, images, and videos, to the scratching of novel molecular structures, the incredible creativity of deep learning generative models surprised us about the height machine intelligence can achieve. The purpose of this paper is to review the latest advances in generative chemistry which relies on generative modeling to expedite the drug discovery process. This review starts with a brief history of artificial intelligence in drug discovery to outline this emerging paradigm. Commonly used chemical databases, molecular representations, and tools in cheminformatics and machine learning are covered as the infrastructure for the generative chemistry. The detailed discussions on utilizing cutting-edge generative architectures, including recurrent neural network, variational autoencoder, adversarial autoencoder, and generative adversarial network for compound generation are focused. Challenges and future perspectives follow.

description: Abstract :

The prominent growth in environmental, social and governance (ESG) investment is evident, with the number of global assets managed sustainably more than doubled over the last decade. This trend is expected to continue until 2030. This type of financial data is positive but given the United Nations stated ’climate emergency’ and ’climate survival’ in society today, there needs to be an even greater acceleration of growth in ESG investment. Unfortunately, significant negativity has emerged on ESG in recent years. This ’Cutting Edge’ study explores the reasons why and how ESG investment has veered off the journey towards enabling society to achieve both its targets under the 2030 United Nations Sustainable Energy Agenda and the 2015 Paris Agreement. It examines the factors prompting leading multinational companies, particularly in the energy and food sectors, to shift their corporate strategies. The key message advanced is that ESG frameworks and guidelines are not problematic; rather, the issue lies in the practice of ethics in decision-making within corporations. Addressing this ethical challenge, which is at the heart of ESG practices, across different professions and disciplines can rebuild trust among stakeholders in ESG investing. This form of interdisciplinary ‘just transition ethics’ can re-orient us back on the journey towards a just and sustainable world

description: This study proposes a new way to manufacture large lightweight aspherics for space telescopes using Stress Mirror Polishing (SMP). This technique is well known to allow reaching high quality optical surfaces in a minimum time period, thanks to a spherical full-size polishing tool. To obtain the correct surface' aspheric shape, it is necessary to define precisely the thickness distribution of the mirror to be deformed, according to the manufacturing parameters. We first introduce active optics and Stress Mirror Polishing techniques, and then, we describe the process to obtain the appropriate thickness mirror distribution allowing to generate the required aspheric shape during polishing phase. Shape optimization procedure using PYTHON programing and NASTRAN optimization solver using Finite Element Model (FEM) is developed and discussed in order to assist this process. The main result of this paper is the ability of the shape optimization process to support SMP technique to generate a peculiar aspherical shape from a spherical optical surface thanks to a thickness distribution reshaping. This paper is primarily focused on a theoretical framework with numerical simulations as the first step before the manufacturing of a demonstrator. This two-steps approach was successfully used for previous projects.

description: Random walks process on networks plays a fundamental role in understanding the importance of nodes and the similarity of them, which has been widely applied in PageRank, information retrieval, and community detection, etc. Individual's memory has been proved to be important to affect network evolution and dynamical processes unfolding on the network. In this manuscript, we study the random-walk process on extended activity driven network model by taking account of individual's memory. We analyze how individual's memory affects random-walk process unfolding on the network when the timescales of the processes of the random walk and the network evolution are comparable. Under the constraints of long-time evolution, we derive analytical solutions for the distribution of stationary state Wa and the mean first-passage time (MFPT) of the random-walk process. We find that, compared with the memoryless activity-driven model, individual's memory enhances the fluctuation of degree distribution, which reduces the capability of gathering walkers for nodes, especially with large activity and delays the mean first-passage time. The results on real networks also support the theoretical analysis with artificial networks.

description: We construct the first examples of deformed non-abelian black strings in a 5-dimensional Einstein-Yang-Mills model. Assuming all fields to be independent of the extra coordinate, we construct deformed black strings, which in the 4-dimensional picture correspond to axially symmetric non-abelian black holes in gravity-dilaton theory. These solutions thus have deformed S^2 x R horizon topology. We study fundamental properties of the black strings and find that for all choices of the gravitational coupling two branches of solutions exist. The limiting behaviour of the second branch of solutions however depends strongly on the choice of the gravitational coupling.

description: Matter in the Universe is arranged in a cosmic web, with a filament of matter typically connecting each neighbouring galaxy pair, separated by tens of millions of light-years. A quadrupolar pattern of the spin field around filaments is known to influence the spins of galaxies and haloes near them, but it remains unknown whether filaments themselves spin. Here, we measure dark-matter velocities around filaments in cosmological simulations, finding that matter generally rotates around them, much faster than around a randomly located axis. It also exhibits some coherence along the filament. The net rotational component is comparable to, and often dominant over, the known quadrupolar flow. The evidence of net rotations revises previous emphasis on a quadrupolar spin field around filaments. The full picture of rotation in the cosmic web is more complicated and multiscale than a network of spinning filamentary rods, but we argue that filament rotation is substantial enough to be an essential part of the picture. It is likely that the longest coherently rotating objects in the Universe are filaments. Also, we speculate that this rotation could provide a mechanism to generate or amplify intergalactic magnetic fields in filaments.

description: Network theory is rapidly changing our understanding of complex systems, but the relevance of topological features for the dynamic behavior of metabolic networks, food webs, production systems, information networks, or cascade failures of power grids remains to be explored. Based on a simple model of supply networks, we offer an interpretation of instabilities and oscillations observed in biological, ecological, economic, and engineering systems. We find that most supply networks display damped oscillations, even when their units - and linear chains of these units - behave in a non-oscillatory way. Moreover, networks of damped oscillators tend to produce growing oscillations. This surprising behavior offers, for example, a new interpretation of business cycles and of oscillating or pulsating processes. The network structure of material flows itself turns out to be a source of instability, and cyclical variations are an inherent feature of decentralized adjustments. In particular, we show how to treat production and supply networks as transport problems governed by balance equations and equations for the adaptation of production speeds. The stability and dynamic behavior of supply networks is investigated for different topologies, including sequential supply chains, "supply circles", "supply ladders", and "supply hierarchies". Moreover, analytical conditions for absolute and convective instabilities are derived. The empirically observed bullwhip effect in supply chains is explained as a form of convective instability based on resonance effects. An application of this theory to the optimization of production networks has large optimization potentials.

Presenting crosscutting structure with active models
Creators: name: Coelho, Wesley
Publisher: name: University of British Columbia
Year: 2009

description: When performing development tasks, such as modifications and debugging, developers must often understand and manipulate source code that crosscuts a software system's structure. These tasks are made more difficult by limitations of the two approaches currently used to present crosscutting structure: tree views and structure diagrams. Tree views force the developer to manually synthesize information from multiple views; structure diagrams quickly suffer from graphical complexity. We introduce an active model as a means of presenting the right information about the crosscutting structure to a developer at the right time. An active model is produced as a result of three operations—projection, expansion, and abstraction. Combined with particular user interaction features during display,' these operations enable a view of the model to be presented to the developer without suffering from the complexity of existing approaches. We have implemented an active model tool, called ActiveAspect, for presenting crosscutting structure described by AspectJ aspects. We report on the results of a case study in which the tool was used effectively by two subjects to implement a modification task to a non-trivial AspectJ system.

description: The Time-of-Arrival (ToA) of coronal mass ejections (CME) at Earth is a key parameter due to the space weather phenomena associated with the CME arrival, such as intense geomagnetic storms. Despite the incremental use of new instrumentation and the development of novel methodologies, ToA estimated errors remain above 10 hours on average. Here, we investigate the prediction of the ToA of CMEs using observations from heliospheric imagers, i.e., from heliocentric distances higher than those covered by the existent coronagraphs. In order to perform this work we analyse 14 CMEs observed by the heliospheric imagers HI-1 onboard the twin STEREO spacecraft to determine their front location and speed. The kinematic parameters are derived with a new technique based on the Elliptical Conversion (ElCon) method, which uses simultaneous observations from the two viewpoints from STEREO. Outside the field of view of the instruments, we assume that the dynamics of the CME evolution is controlled by aerodynamic drag, i.e., a force resulting from the interaction with particles from the background solar wind. To model the drag force we use a physical model that allows us to derive its parameters without the need to rely on drag coefficients derived empirically. We found a CME ToA mean error of $1.6\pm8.0$ hours ToA and a mean absolute error of $6.9\pm3.9$ hours for a set of 14 events. The results suggest that observations from HI-1 lead to estimates with similar errors to observations from coronagraphs.

BitVampire : a cost-effective architecture for on-demand media streaming in heterogeneous P2P networks

Year: 2009

description: On-demand media streaming has recently gained intensive consideration due to its promising usage in a rich set of Internet-based services such as video on demand, distance learning, media distribution, etc. However, there are still many challenges towards building efficient, scalable, on-demand streaming systems, in this thesis, we propose a novel cost-effective on-demand media streaming architecture for heterogeneous peer-to-peer networks, named BitVampire. The key idea of BitVampire is to aggregate peers' storage and bandwidths to facilitate on-demand media streaming. To achieve this goal, we split published videos into segments and distribute them to different peers. When watching a video, a peer searches the corresponding segments, and then aggregates bandwidths from multiple supplying peers to stream the video. To deploy this architecture in a dynamic heterogeneous peer-to-peer network, three key techniques are used: (1) Given that peers offer different resources and may leave at any time, a media segments distributing algorithm and a caching scheme are proposed, which achieve fast system streaming capacity amplification. (2) An application-level overlay, called Category Overlay, is chosen as the underlying search infrastructure to efficiently find the desired segments. (3) A scheduling algorithm is proposed to aggregate bandwidths from multiple supplying peers and coordinate them to serve one streaming request. We demonstrate the effectiveness of this proposed architecture through extensive simulation experiments on large, Internet-like topologies.

description: The objective of this paper is to empirically compare the predictive power of the hedonic model with an artificial neural network model on house price prediction. A sample of 200 houses in Christchurch, New Zealand is randomly selected from the Harcourt website. Factors including house size, house age, house type, number of bedrooms, number of bathrooms, number of garages, amenities around the house and geographical location are considered. Empirical results support the potential of artificial neural network on house price prediction, although previous studies have commented on its black box nature and achieved different conclusions.

description: When analyzed in terms of the Symanzik expansion, lattice correlators of multi-local (gauge-invariant) operators with non-trivial continuum limit exhibit in maximally twisted lattice QCD ``infrared divergent'' cutoff effects of the type a^{2k}/(m_π^2)^{h}, 2k\geq h\geq 1 (k,h integers), which tend to become numerically large when the pion mass gets small. We prove that, if the action is O(a) improved a` la Symanzik or, alternatively, the critical mass counter-term is chosen in some ``optimal'' way, these lattice artifacts are reduced to terms that are at worst of the order a^{2}(a^2/m_π^2)^{k-1}, k\geq 1. This implies that the continuum extrapolation of lattice results is smooth at least down to values of the quark mass, m_q, satisfying the order of magnitude inequality m_q >a^2Λ^3_{\rm QCD}.

description: A familiar problem in space and astrophysical plasmas is to understand how dissipation and heating occurs. These effects are often attributed to the cascade of broadband turbulence which transports energy from large scale reservoirs to small scale kinetic degrees of freedom. When collisions are infrequent, local thermodynamic equilibrium is not established. In this case the final stage of energy conversion becomes more complex than in the fluid case, and both pressure-dilatation and pressure strain interactions (Pi-D $\equiv -Π_{ij} D_{ij}$) become relevant and potentially important. Pi-D in plasma turbulence has been studied so far primarily using simulations. The present study provides a statistical analysis of Pi-D in the Earth's magnetosheath using the unique measurement capabilities of the Magnetospheric Multiscale (MMS) mission. We find that the statistics of Pi-D in this naturally occurring plasma environment exhibit strong resemblance to previously established fully kinetic simulations results. The conversion of energy is concentrated in space and occurs near intense current sheets, but not within them. This supports recent suggestions that the chain of energy transfer channels involves regional, rather than pointwise, correlations.

description: The 2002 New Zealand Transport Strategy states that in the long run, economic development and transport activity need not be directly related. This implies that a degree of „decoupling‟ is required – that economic development needs to occur without similar growth in transport. Before evaluating the possible impacts of policies that may be introduced to achieve decoupling, it is vital to consider what might happen to the relationship between economic development and transport over the next 50 or 100 years. Two key factors that are likely to impact upon this relationship in the future are demographic change and structural change. This paper suggests that in the absence of any policy change, some decoupling of economic development and transport may take place as a result of these two factors. However, income growth and transport demand from the rapidly growing tourism sector may push total transport growth use up.
