description: We propose a multilevel approach for trace systems resulting from hybridized discontinuous Galerkin (HDG) methods. The key is to blend ideas from nested dissection, domain decomposition, and high-order characteristic of HDG discretizations. Specifically, we first create a coarse solver by eliminating and/or limiting the front growth in nested dissection. This is accomplished by projecting the trace data into a sequence of same or high-order polynomials on a set of increasingly $h-$coarser edges/faces. We then combine the coarse solver with a block-Jacobi fine scale solver to form a two-level solver/preconditioner. Numerical experiments indicate that the performance of the resulting two-level solver/preconditioner depends only on the smoothness of the solution and is independent of the nature of the PDE under consideration. While the proposed algorithms are developed within the HDG framework, they are applicable to other hybrid(ized) high-order finite element methods. Moreover, we show that our multilevel algorithms can be interpreted as a multigrid method with specific intergrid transfer and smoothing operators. With several numerical examples from Poisson, pure transport, and convection-diffusion equations we demonstrate the robustness and scalability of the algorithms.

description: Time-domain astrophysics has leaped forward with the direct discovery of gravitational waves and the emergence of new generation instruments for multi-messenger studies. The capacity of the multi-messenger multi-wavelength community to effectively pursue follow-up observations is hindered by the suboptimal localization of numerous transient events and the escalating volume of alerts. Thus, we have developed an effective tool to overcome the observational and technical hurdles inherent in the emerging field of multi-messenger astrophysics. We present tilepy, a Python package for the automatic scheduling of follow-up observations of poorly localized transient events. It is ideally suited to tackle the challenge of complex follow-up in mid and small-FoV telescope campaigns, with or without human intervention. We demonstrate the capabilities of tilepy in the realm of multi-observatory, multi-wavelength campaigns, to cover the localization uncertainty region of various events ultimately aiming at pinpointing the source of the multi-messenger emission. The tilepy code is publicly available on GitHub and is sufficiently flexible to be employed either automatically or in a customized manner, tailored to collaboration and individual requirements. tilepy is also accessible via a public API and through the Astro-COLIBRI platform.

description: This study aimed to assess the potential of using spent white button mushroom substrate (SMS) as replacement for peat for producing cherry tomato seedlings, considering different proportions of fresh and composted SMS. Phase I focused on testing the performance of seedlings raised in different growing media mixes and Phase II on the assessment of the subsequent yields of the tomatoes raised in selected treatments. Results showed that the use of fresh SMS as a replacement for the peat-based control substrate was limited to 20% (% w/v), due to its high salinity. However, the control substrate could be replaced completely with composted SMS (Composted SMS 100) without any significant differences in the growth of the seedlings. Based on the most promising results from Phase I, yields of plants raised in composted SMS (Composted SMS 40 and 100), fresh SMS (Fresh SMS 20), and peat-based control were compared. There were no significant differences in the total yield (mass) between the treatments, but the average total number of fruits of the five harvest dates was higher in the Composted SMS 100 and in the control than in the other treatments. Notably, Composted SMS 100 and control produced greater mass of tomatoes at the final harvest. In conclusion, SMS provided an effective alternative for production of cherry tomato seedlings, with composting of the SMS before use being a crucial step. It was recommended that no more than 20% fresh SMS should be used to replace peat to ensure optimal growth of cherry tomato seedlings.

description: Directed evolution is a powerful tool that mimics the natural selection process to engineer biomolecules with improved and altered functionalities for a wide variety of applications. The advance of biological engineering based on directed evolution techniques depends upon selection assays that can practically search large, diverse libraries for the most improved variants. In Chapter 1, we begin by discussing the potential of growth selections to serve as accessible and robust assays for directed evolution. We then delve into the existing approaches to expand the scope of targets for growth selections beyond those that are intrinsically linked to growth and the strategies implemented to improve their throughput and sensitivity.
      The yeast three-hybrid (Y3H) assay is a versatile system that can expand the field of directed evolution if implemented as a growth selection for the search of large variant libraries. Although the Y3H assay has been successfully applied as a positive selection to evolve proteins with improved functions, its expansion into applications requiring a high-throughput, versatile selection against transcriptional activation has been hindered by its limited dynamic range as a counter selection. To address the limited dynamic range of the Y3H assay, we undertook a multi-pronged approach to reengineer our Y3H counter selection to have a high dynamic range. In Chapter 2, we discuss strategies to improve the dynamic range of the Y3H counter selection by maximizing the growth between cells with activated and basal reporter gene expression levels. Specifically, we elaborate on the development and characterization of two Y3H counter selections that were based on either reporter gene degradation or an alternative phototoxic reporter gene. In Chapter 3, we present our most successful strategy to improve the dynamic range of the Y3H counter selection that uses the dual tetracycline (Tet) system to increase transcriptional regulation of the reporter gene. We employed a guided strategy based on both rational design and library approaches to find the best Tet Y3H reporter gene construct with the highest dynamic range. We believe our method to engineer the best Tet Y3H reporter construct will be widely useful to synthetic biologists developing sophisticated in vivo assays that require fine-tuned reporter gene expression levels. Finally, in Chapter 4, we demonstrate the versatility of the Y3H system by developing a screen for the detection of natural product biosynthesis. This assay should have an impact for metabolic engineers that are employing directed evolution techniques to generate large metabolic pathway libraries for the overproduction of high-value small molecules in heterologous producer strains.

description: In this paper we re-examine the one-dimensional interaction of electromagnetic and ion acoustic waves in a plasma. Our model is similar to one solved by Rao et al. (Phys. Fluids, vol. 26, 2488 (1983)) under a number of analytical approximations. Here we perform a numerical investigation to examine the stability of the model. We find that for slightly over dense plasmas, the propagation of stable solitary modes can occur in an adiabatic regime where the ion acoustic electric field potential is enslaved to the electromagnetic field of a laser. But if the laser intensity or plasma density increases or the laser frequency decreases, the adiabatic regime loses stability via a transition to chaos. New asymptotic states are attained when the adiabatic regime no longer exists. In these new states, the plasma becomes rarefied, and the laser field tends to behave like a vacuum field.

description: Late blight caused by Phytophthora infestans is the most devastating disease for cultivated potatoes, causing considerable financial loss annually due to loss of yield and costs of fungicide applications. For organic farming especially, the strict limitations on the use of fungicides makes research necessary to investigate factors that influence disease severity. Therefore, effects of nitrogen fertiliser rates on leaf and tuber blight in organically grown potato cultivars and pre-breeding clones were evaluated in the present study. It was found that the foliage of the pre-breeding clones was little, or not at all, affected by P. infestans, irrespectively of the nitrogen application rate, while the cultivars reacted differently with mild to strong late blight symptoms. Only some of the clones and cultivars showed increased infection of tubers at the higher nitrogen application rates, whilst most showed no significant differences between the N rates. Overall, the present study showed that the use of new resistant cultivars could be a suitable approach to reduce late blight in organic farming, where soil nitrogen levels may vary due to the use of different forms of nutrient inputs with varying mineralisation rates.

description: We introduce a permissioned distributed ledger technology (DLT) design for crowdsourced smart mobility applications. This architecture is based on a directed acyclic graph architecture (similar to the IOTA tangle) and uses both Proof-of-Work and Proof-of-Position mechanisms to provide protection against spam attacks and malevolent actors. In addition to enabling individuals to retain ownership of their data and to monetize it, the architecture also is suitable for distributed privacy-preserving machine learning algorithms, is lightweight, and can be implemented in simple internet-of-things (IoT) devices. To demonstrate its efficacy, we apply this framework to reinforcement learning settings where a third party is interested in acquiring information from agents. In particular, one may be interested in sampling an unknown vehicular traffic flow in a city, using a DLT-type architecture and without perturbing the density, with the idea of realizing a set of virtual tokens as surrogates of real vehicles to explore geographical areas of interest. These tokens, whose authenticated position determines write access to the ledger, are thus used to emulate the probing actions of commanded (real) vehicles on a given planned route by "jumping" from a passing-by vehicle to another to complete the planned trajectory. Consequently, the environment stays unaffected (i.e., the autonomy of participating vehicles is not influenced by the algorithm), regardless of the number of emitted tokens. The design of such a DLT architecture is presented, and numerical results from large-scale simulations are provided to validate the proposed approach.

description: Weeds are a major component of agricultural diversity affecting crop yield and ecosystem services. Compared to modern wheat (Triticum aestivum) varieties, ancient wheat cultivars (released before 1960) are taller, and this trait can be used to control weeds in organic farming systems. However, there is still a lack of quantitative assessments of the relative contribution of wheat breeding-history (ancient vs modern varieties) and synthetic inputs in explaining weed density and community structure. In this study, a field experiment was undertaken where five modern and five ancient wheat varieties were either treated as in a conventional system with synthetic inputs (nitrogen, herbicide and fungicide) or as in an organic system without the use of synthetic inputs. Crop light interception and weed density were recorded for 12 weeks until crop maturity. On average, ancient varieties reduced weed density by 17% compared with modern varieties, while the application of chemical inputs was responsible for an average reduction of 37%. The stronger competitive effect of ancient varieties was associated with increased sunlight interception. Species richness was higher in the absence of inputs for some weeks, but not by the end of the experiment. The field-based results illustrated that ancient varieties can be used to help control weed density in organic systems that do not rely on synthetic inputs for weed control Despite this effect of crop interference on weed density, a reduction in weed diversity was not observed. These findings could be of particular interest to promote agrobiodiversity in agricultural systems without synthetic inputs.
Through conceptual planning to sustainable landscapes at Highland Valley Copper

description: The Highland Valley Copper mine site in south-central British Columbia is the largest base metals mine in North America and is comprised of four distinct mining areas: Lornex, Valley, Highmont and Bethlehem. Reclamation studies and programs have been under way at Bethlehem and Lornex since 1970 and extensive areas of wastes have been reclaimed. Large scale reclamation of the Highmont site began in 1988. Mining disturbances are scheduled for reclamation as soon as areas become permanently inactive and these activities are planned to continue through the year 2016. Land use objectives for the various portions of the mine site are defined in the conceptual reclamation plan and are refined as operational scale plans are developed. Issues and constraints include the physical properties of the various waste materials, range of climatic conditions, metal content of plants grown on wastes, chemistry of water sources, and the requirements of various end land users. Examples are given of levels of planning detail and of mine areas restored for various land uses.

description: The 21st century offers technology advancement and engagement with the passive, static information of print and website media as well as interactive social networking media on the Internet. Children born into this era quickly learn the language, join the digital community, and engage with these technologies. However, older adults who were not born into this dynamic technological era grapple with the constant changes that are explained by Moore's law. This has resulted in a digital skills and knowledge divide that sees older adults excluded from full inVol.vement in dynamic communities that included digital engagement. In order to reduce this digital divide, we need first to understand why some older adults engage with computer and internet technologies therefore, this thesis explores the engagement modes of older adults using computer and internet technologies. The research questions of this thesis are ‘Do older adults’ engagement modes influence their perception about computer and internet technology use?’ and ‘Can understanding these engagement modes help address digital divide issues facing older adults?’ A multi-method approach was undertaken as this enabled the researcher to explore the phenomena using both qualitative and quantitative methods providing rigorous and robust results. This was achieved through two studies that were conducted over a period of five years. The first study explored whether there is a difference between older adult and younger adult engagement modes, as well as any relationship between older adults’ perceived usefulness of the technology and their engagement modes. The second study was confirmatory analysis of the results of study one, which incorporated participant observation to test whether the engagement modes were observable and how these observations, could be explained.

description: The presented study evaluated different manufacturing procedures of breakfast cereals in view of their ability to preserve the natural quality of the raw material, as this is recommended by the EU Regulation 2018/848 for organic farming and the Demeter guidelines. From four crops (spelt, buckwheat, rice and quinoa), different products were manufactured: flakes, roasted flakes from cooked grains, extrudates from dough, and puffed grains. The samples (in total n = 18) were analysed for positive (thiamine, folate, lysine) and negative (acrylamide) health-related constituents, delayed fluorescence by Fluorescence Excitation Spectroscopy (FES) and food-induced emotions by the EmpathicFoodTest (EFT). The results showed that the four crops reacted similarly to the manufacturing processes, but the sensitivity of the crop was different for the health-related constituents, with spelt and rice showing greater sensitivity with respect to acrylamide formation and thiamine loss, than buckwheat and quinoa (though differences at the individual crop level were not statistically verified). The different assessment methods led to largely consistent evaluations of the processing methods: after extrusion, puffing and roasting flakes, significant quality losses were observed. Depending on the parameter of the test method, the classification of the degradation due to processing differed slightly: lysine degradation was significantly higher in puffed products (especially in rice and spelt) and acrylamide concentration was high (> 200 µg kg-1) in roasted and puffed spelt. The methods EFT and FES rated extruded samples particularly unfavourably. The least harmful process in all parameters was the production of flakes.

China's far below replacement level fertility: a reality or illusion arising from underreporting of births?
Creators: name: Zhang, Guangyu
Publisher: name: The Australian National University
Year: 2004
Subjects: China • below-replacement fertility • underreporting of births • data quality • population statistics

description: How fast and how far China’s fertility declined in the 1990s has long been a matter of considerable debate, despite very low fertility consistently being reported in a number of statistical investigations over time. Most demographers interpreted this as a result of serious underreporting of births in population statistics, due to the family planning program, especially the program strengthening after 1991. Consequently, they suggested that fertility fell only moderately below-replacement level, around 1.8 children per woman from the early 1990s. But some demographers argued that surveys and census may have reflected a real decline of fertility even allowing for some underreporting of births, given the consistency between data sources and over time. They believed that fertility declined substantially in the 1990s, very likely in the range between 1.5 and 1.6 by the year 2000.¶ The controversy over fertility is primarily related to the problem of underreporting of births, in particular the different estimations of the extent of underreporting. However, a correct interpretation of fertility data goes far beyond the pure numbers, which calls for a thorough understanding of different data sources, the programmatic and societal changes that occurred in the 1990s, and their effects on both fertility changes and data collection efforts. This thesis aims to address the question whether the reported far-below-replacement level fertility was a reality of substantial fertility decline or just an illusion arising from underreporting of births. Given the nature of the controversy, it devotes most efforts in assessing data quality, through examining the patterns, causes and extent of underreporting of births in each data source; reconstructing the decline of fertility in the 1990s; and searching corroborating evidence for the decline.¶

Russelia equisetiformis occupies the lowest position vs Scrophularia xanthoglossa. The former species exhibits a considerable number of less advanced characters viz. five distinct sepals, sepal median bundles origin from the central stele, numerous sepal vascular bundles, five petals, dithecous anthers, five staminal traces from the central stele, dorsal carpellary bundles arose from the central stele, lateral carpellary bundles numerous, nectariferous disc vascularized and the compitum is wanting. Scrophularia xanthoglossa shows several advanced characters viz. sepal median, sepal marginal and petal bundles protruding from vascular complexes, bilipped corolla tube (2,3), monothecous anthers, one suppressed staminal bundle, two ventral carpellary bundles, non-vascularized nectariferous disc and presence of a compitum. Paulownia tomentosa acquired the second level of primitiveness after the Russelia among the studied taxa, owing to the subsequent characters viz. five sepals, sepal median, sepal marginal, petal, staminal and dorsal carpellary bundles arising from the central stele, five petals, dithecous anthers, lateral carpellary bundles from the dorsal carpellary mass, four ventral carpellary bundles and absence of compitum.

description: In this paper, we provide a system theoretic treatment of a new class of multilinear time-invariant (MLTI) systems in which the states, inputs and outputs are tensors, and the system evolution is governed by multilinear operators. The MLTI system representation is based on the Einstein product and even-order paired tensors. There is a particular tensor unfolding which gives rise to an isomorphism from this tensor space to the general linear group, i.e. the group of invertible matrices. By leveraging this unfolding operation, one can extend classical linear time-invariant (LTI) system notions including stability, reachability and observability to MLTI systems. While the unfolding based formulation is a powerful theoretical construct, the computational advantages of MLTI systems can only be fully realized while working with the tensor form, where hidden patterns/structures can be exploited for efficient representations and computations. Along these lines, we establish new results which enable one to express tensor unfolding based stability, reachability and observability criteria in terms of more standard notions of tensor ranks/decompositions. In addition, we develop a generalized CANDECOMP/PARAFAC decomposition and tensor train decomposition based model reduction framework, which can significantly reduce the number of MLTI system parameters. We demonstrate our framework with numerical examples.

Revegetation of saline land caused by potash mining activity
Creators: name: Thorpe, Mark B.
name: Neal, Dick, 1943-
Publisher: name: The University of British Columbia

description: Potash mining in Saskatchewan produces 20 million tonnes of waste salt (NaCl) each year. The salt is stored in surface piles which are primarily eroded by precipitation. The resulting brine is contained by a system of dykes but seepage through the dykes has salinized adjacent areas at most mines sites. Our study investigated ways of revegetating a severely salinized area at one mine. Two 30 cm deep surface amendments, topsoil and sewage sludge, were applied to the area and salt and water movements were monitored in the amendments for three years. Topsoil became severely salinized during the first summer and all the seeded grasses growing on it were killed. Sewage sludge sustained vegetation for three years. A greenhouse column experiment indicated that surface evaporation was the key factor determining salt movement into the two amendments. Field and greenhouse results were accurately simulated by the Trasee/Tracon computer model (r² values > 0.86 for sewage sludge). The model was used to simulate salt movement into different depths of amendments under various microclimatic conditions in order to assess the long-term suitability of the amendments to support vegetation.

description: In this thesis, parameterizations of non-linear interactions in quasigeostrophic (QG) flows for severely truncated models (STM) and Large Eddy Simulations (LES) are studied. Firstly, using Direct Numerical Simulations (DNS), atmospheric barotropic flows over topography are examined, and it is established that such flows exhibit multiple equilibrium states for a wide range of parameters. A STM is then constructed, consisting of the large scale zonal flow and a topographic mode. It is shown that, qualitatively, this system behaves similarly to the DNS as far as the interaction between the zonal flow and topography is concerned, and, in particular, exhibits multiple equilibrium states. By fitting the analytical form of the topographic stationary wave amplitude, obtained from the STM, to the results obtained from DNS, renormalized dissipation and rotation parameters are obtained. The usage of renormalized parameters in the STM results in better quantitative agreement with the DNS.¶ In the second type of problem, subgrid-scale parameterizations in LES are investigated with both atmospheric and oceanic parameters. ...

description: A standard microstrip patch antenna has narrow bandwidth thus making it inappropriate for many wireless communication systems. Therefore in this paper we present imprinting of Hilbert curve slot on patch antenna to analyze its effects on the bandwidth. Multiple iterations of Hilbert curve are being implemented and relationship between the iterations and bandwidth is studied. It is observed that increase in iteration will result in increase in bandwidth. As the number of iterations increase the total area of the slot decreases, whereas the length of the slot remain the same within the area. The simulated result depicts that-10 dB bandwidth is achieved at 2.4 GHz which is the operable frequency of WLAN and Bluetooth.

description: The equation $$ \partial_tu=u\partial^2_{xx}u-(c-1)(\partial_xu)^2 $$ is known in literature as a qualitative mathematical model of some biological phenomena. Here this equation is derived as a model of the groundwater flow in a water absorbing fissurized porous rock, therefore we refer to this equation as a filtration-absorption equation. A family of self-similar solutions to this equation is constructed. Numerical investigation of the evolution of non-self-similar solutions to the Cauchy problems having compactly supported initial conditions is performed. Numerical experiments indicate that the self-similar solutions obtained represent intermediate asymptotics of a wider class of solutions when the influence of details of the initial conditions disappears but the solution is still far from the ultimate state: identical zero. An open problem caused by the nonuniqueness of the solution of the Cauchy problem is discussed.
