description: Compared to both Canada and the United States, Australia has been slow to approve commercial planting of transgenic crops. Two probable reasons exist for the slow approval rate of transgenic crops in Australia. The first reason is community perceptions about the risks associated with transgenic technologies. The second is the regulatory framework currently employed to approve commercial releases. This paper examines some of the potential regulatory issues that may be affecting the review process and approval of transgenic technologies. First we provide a brief introduction to the regulatory structure in Australia, second we consider the impact of regional, national and state jurisdictions, third we argue that the regulator needs to consider the use of benefits analysis in decision making, fourth we argue for the use of probabilistic risk assessments in certain circumstances, and fifth we look at potential problems inherent in majority voting in a committee and recommend alternatives.

description: Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the models, primary data were collected from the same 239 farm households in three regions of Hungary. Combining approaches leads to a more efficient and robust estimation of the private value of agrobiodiversity in home gardens. Findings can be used to identify those farming communities, which would benefit most from agri-environmental schemes that support agrobiodiversity maintenance, at least public cost.
Exploration of molecular methods for detecting individual inbreeding levels in mimulus
Creators: name: Leblanc, Marissa Erin
Publisher: name: University of British Columbia
Year: 2009

description: Inbreeding directly affects fitness and population dynamics by way of inbreeding depression and is particularly prevalent in plants and in small populations. While the importance of measuring fitness and inbreeding levels in natural populations is clear, it is difficult to do in practice. As an alternative, molecular methods have been developed for estimating individual inbreeding levels. These methods may also offer insight into fitness because in the presence of inbreeding depression, inbreeding level will negatively correlate with fitness. While some molecular methods for estimating inbreeding levels apply to any codominant marker, others have been specifically constructed for microsatellites, a type of genetic marker that roughly follows the stepwise mutation model (Ohta and Kimura, 1973). This model has provided the foundation for microsatellite-specific measures. Unlike conventional measures of inbreeding levels (e.g individual heterozygosity), microsatellite-specific measures possibly detect historical levels of inbreeding. The purpose of this thesis is to explore the correlation between various inbreeding measures and fitness. A literature review of empirical and theoretical treatments of the first microsatellite-specific measure, d² (Coulson et al., 1998), revealed that d² was sometimes, but not always, more correlated with fitness than was individual heterozygosity. The pattern in the literature suggests that populations may differ in their extent of historical inbreeding. The literature review also indicated that exploration of d² in closely related taxa of different selfing rates was still warranted. Furthermore, the analytical modeling of Tsitrone etal. (2001) provided the inspiration for the development of new microsatellite-specific measures that distinguish between small repeat differences but pool larger repeat differences together. An empirical study of microsatellite-specific measures for detecting individual inbreeding levels was carried out in four taxa with known differences in selfing rates in the Mimulus guttatus species complex. Genotype-fitness correlations are driven by inbreeding levels, extent of inbreeding depression, and linkage disequilibrium, all of which are influenced by selfing rate. It was hypothesized that different measures might best correlate with fitness in inbreeding taxa than in outbreeders. However no genotype-fitness correlations were observed for any measure or in any of the species. This study shows that even in the presence of within-population variation in inbreeding levels, genotype-fitness correlations may not be detectable. Although inbreeding issues are most pressing in small populations, molecular methods for detecting inbreeding level do not perform well under these circumstances (Ritland, 1996; Tsitrone et al., 2001).

description: This paper presents the assessment of time-dependent national-level restrictions and control actions and their effects in fighting the COVID-19 pandemic. By analysing the transmission dynamics during the first wave of COVID-19 in the country, the effectiveness of the various levels of control actions taken to flatten the curve can be better quantified and understood. This in turn can help the relevant authorities to better plan for and control the subsequent waves of the pandemic. To achieve this, a deterministic population model for the pandemic is firstly developed to take into consideration the time-dependent characteristics of the model parameters, especially on the ever-evolving value of the reproduction number, which is one of the critical measures used to describe the transmission dynamics of this pandemic. The reproduction number alongside other key parameters of the model can then be estimated by fitting the model to real-world data using numerical optimisation techniques or by inducing ad-hoc control actions as recorded in the news platforms. In this paper, the model is verified using a case study based on the data from the first wave of COVID-19 in the Republic of Kazakhstan. The model is fitted to provide estimates for two settings in simulations; time-invariant and time-varying (with bounded constraints) parameters. Finally, some forecasts are made using four scenarios with time-dependent control measures so as to determine which would reflect on the actual situations better.

description: Machine learning (ML) methods have recently been used as forward solvers to predict the mechanical properties of composite materials. Here, we use a supervised-autoencoder (sAE) to perform inverse design of graphene kirigami, where predicting the ultimate stress or strain under tensile loading is known to be difficult due to nonlinear effects arising from the out-of-plane buckling. Unlike the standard autoencoder, our sAE is able not only to reconstruct cut configurations but also to predict mechanical properties of graphene kirigami and classify the kirigami witheither parallel or orthogonal cuts. By interpolating in the latent space of kirigami structures, the sAE is able to generate novel designs that mix parallel and orthogonal cuts, despite being trained independently on parallel or orthogonal cuts. Our method allows us to both identify novel designs and predict, with reasonable accuracy, their mechanical properties, which is crucial for expanding the search space for materials design.

description: Pruning the parameters of deep neural networks has generated intense interest due to potential savings in time, memory and energy both during training and at test time. Recent works have identified, through an expensive sequence of training and pruning cycles, the existence of winning lottery tickets or sparse trainable subnetworks at initialization. This raises a foundational question: can we identify highly sparse trainable subnetworks at initialization, without ever training, or indeed without ever looking at the data? We provide an affirmative answer to this question through theory driven algorithm design. We first mathematically formulate and experimentally verify a conservation law that explains why existing gradient-based pruning algorithms at initialization suffer from layer-collapse, the premature pruning of an entire layer rendering a network untrainable. This theory also elucidates how layer-collapse can be entirely avoided, motivating a novel pruning algorithm Iterative Synaptic Flow Pruning (SynFlow). This algorithm can be interpreted as preserving the total flow of synaptic strengths through the network at initialization subject to a sparsity constraint. Notably, this algorithm makes no reference to the training data and consistently competes with or outperforms existing state-of-the-art pruning algorithms at initialization over a range of models (VGG and ResNet), datasets (CIFAR-10/100 and Tiny ImageNet), and sparsity constraints (up to 99.99 percent). Thus our data-agnostic pruning algorithm challenges the existing paradigm that, at initialization, data must be used to quantify which synapses are important.

description: In order to discuss the well-posed initial value formulation of the teleparallel gravity and apply it to numerical relativity a symmetric hyperbolic system in the self-dual teleparallel gravity which is equivalent to the Ashtekar formulation is posed. This system is different from the ones in other works by that the reality condition of the spatial metric is included in the symmetric hyperbolicity and then is no longer an independent condition. In addition the constraint equations of this system are rather simpler than the ones in other works.

description: In the digital era, users share their personal data with service providers to obtain some utility, e.g., access to high-quality services. Yet, the induced information flows raise privacy and integrity concerns. Consequently, cautious users may want to protect their privacy by minimizing the amount of information they disclose to curious service providers. Service providers are interested in verifying the integrity of the users' data to improve their services and obtain useful knowledge for their business. In this work, we present a generic solution to the trade-off between privacy, integrity, and utility, by achieving authenticity verification of data that has been encrypted for offloading to service providers. Based on lattice-based homomorphic encryption and commitments, as well as zero-knowledge proofs, our construction enables a service provider to process and reuse third-party signed data in a privacy-friendly manner with integrity guarantees. We evaluate our solution on different use cases such as smart-metering, disease susceptibility, and location-based activity tracking, thus showing its versatility. Our solution achieves broad generality, quantum-resistance, and relaxes some assumptions of state-of-the-art solutions without affecting performance.
The power in dialogue : exploring the experiences of involuntary adolescent clients
Creators: name: Doyle, Janet Marie
Publisher: name: University of British Columbia
Year: 2009

description: Social Workers providing service to involuntary clients may be challenged with the ethical issues linked to such services. The primary ethical issues in working with involuntary clients are the infringement on self-determination and the use of paternalism and whether either is justified. Work with involuntary clients may also raise the issue of balancing the social worker's responsibilities to both the welfare of the individual and the welfare of the many. Another concern for social work is that the use of paternalistic interventions has the potential to move social work as a profession into a role of solely providing social control. The studies involving involuntary clients have focused on the success or lack of success these clients have achieved through treatment or intervention. The studies may not be helpful for workers struggling with the ethical issues involved in working with involuntary clients. This study explores the experiences of a small number of adolescents who self-identified as involuntary clients. Confidential interviews were conducted with the participants. The interview data was analyzed in a manner consistent with phenomenological study methods. The results indicate that the experience of being an involuntary adolescent client included feeling controlled and labelled. The experience also included feelings of power, acceptance, and validation. The results of this study provide information that social workers might reflect on before making decisions regarding the use of paternalistic interventions or before providing service to involuntary clients.

Electron channeling experiments with bent silicon single crystals -- a reanalysis based on a modified Fokker-Planck equation

description: A surprising small dechanneling length was observed at (111) channeling of ultrarelativistic electrons in a 60 $μ$m thick silicon single crystal with a bending radius of 0.15 m. The experiments were conducted at beam energies between 3.35 and 14 GeV at the Facility for Advanced Accelerator Experimental Tests (FACET at SLAC, USA). It is shown in this paper that the small dechanneling lengths can well be reproduced with a modified Fokker-Planck equation for plane crystals in which a crystal bending has been heuristically introduced. Encouraged by this result experiments have been reconsidered which were performed at the Mainz Microtron MAMI with (110) silicon undulator crystals. The results obtained with the modified Fokker-Planck equation suggest that the observed rather low undulator peak intensity originates from the strongly reduced dechanneling length of electrons in the bent sections of the undulator. A scaling law derived on the basis of the modified Fokker-Planck equation reveals optimized parameters of electron based undulators as possible radiation sources in the $X$- and $γ$-ray region.

description: The possible description of the vacuum of quantum gravity through the so called kappa--Poincare group is analyzed considering some of the consequences of this symmetry in the path integral formulation of nonrelativistic quantum theory. This study is carried out with two cases, firstly, a free particle, and finally, the situation of a particle immersed in a homogeneous gravitational field. It will be shown that the kappa--Poincare group implies the loss of some of the basic properties associated to Feynman's path integral. For instance, loss of the group characteristic related to the time dependence of the evolution operator, or the breakdown of the composition law for amplitudes of events occurring successively in time. Additionally some similarities between the present idea and the so called restricted path integral formalism will be underlined. These analogies advocate the claim that if the kappa--Poincare group contains some of the physical information of the quantum gravity vacuum, then this vacuum could entail decoherence. This last result will also allow us to consider the possibility of analyzing the continuous measurement problem of quantum theory from a group--theoretical point of view, but now taking into account the kappa--Poincare symmetries.

description: The amniotic fluid that surrounds the human embryo possesses compounds with antimicrobial activity needed to protect the fetus. Here we hypothesized that the mucilaginous tissue (biogel) that naturally coats cucurbit seeds (e.g. cucumber) may exhibit antimicrobial protection by hosting beneficial microbes with antagonistic activity against pathogens. We isolated 34 unique strains from the wash of aseptically isolated fresh seeds, including the mucilage, belonging to 3 domesticated cucurbits [cucumber (Cucumis sativus), cantaloupe (Cucumis melo), pumpkin (Cucurbita pepo)] and a wild non-edible cucumber species (Echinocystis lobata) native to North America. The seed biogels were discovered to have bacterial 16S rRNA sequences (endophytes) which could be assigned to 12 bacterial genera within three phyla (Firmicutes, Proteobacteria and Actinobacteria). Bacillus was the most dominant genus constituting 32% of the identified endophytes. Interestingly, 62% of the biogel bacteria showed in vitro antagonism against 4 major soil-borne phytopathogens (Fusarium graminearum, Rhizoctonia solani, Phytophthora capsici, Pythium aphanidermatum). We conclude that cucurbit seeds package protective disease-suppressive microbes in their biogels. We speculate that the biogel microbiomes protect germinating seeds and seedlings against soil borne pathogens.

description: Background - Patient-Derived Tumour Xenografts (PDTXs) have emerged as the pre-clinical models that best represent clinical tumour diversity and intra-tumour heterogeneity. The molecular characterization of PDTXs using High-Throughput Sequencing (HTS) is essential; however, the presence of mouse stroma is challenging for HTS data analysis. Indeed, the high homology between the two genomes results in a proportion of mouse reads being mapped as human. Results - In this study we generated Whole Exome Sequencing (WES), Reduced Representation Bisulfite Sequencing (RRBS) and RNA sequencing (RNA-seq) data from samples with known mixtures of mouse and human DNA or RNA and from a cohort of human breast cancers and their derived PDTXs. We show that using an In silico Combined human-mouse Reference Genome (ICRG) for alignment discriminates between human and mouse reads with up to 99.9% accuracy and decreases the number of false positive somatic mutations caused by misalignment by >99.9%. We also derived a model to estimate the human DNA content in independent PDTX samples. For RNA-seq and RRBS data analysis, the use of the ICRG allows dissecting computationally the transcriptome and methylome of human tumour cells and mouse stroma. In a direct comparison with previously reported approaches, our method showed similar or higher accuracy while requiring significantly less computing time. Conclusions - The computational pipeline we describe here is a valuable tool for the molecular analysis of PDTXs as well as any other mixture of DNA or RNA species.

description: Using a set of cosmological hydro-dynamical simulations, we constrained the properties of primordial magnetic fields by studying their impact on the formation and evolution of dwarf galaxies. We performed a large set of simulations (8 dark matter only and 72 chemo-hydrodynamical) including primordial magnetic fields through the extra density fluctuations they induce at small length scales ($k \geq 10\,h\,\rm{Mpc^{-1}}$) in the matter power spectrum. We explored a large variety of primordial magnetic fields with strength $B_λ$ ranging from $0.05$ to $0.50\,\textrm{nG}$ and magnetic energy spectrum slopes $n_B$ from $-2.9$ to $-2.1$. Strong magnetic fields characterized by a high amplitude ($B_λ=0.50,\,0.20\,\textrm{nG}$ with $n_B=-2.9$) or by a steep initial power spectrum slope ($n_B=-2.1,-2.4$, with $B_λ=0.05\,\textrm{nG}$) induce perturbations in the mass scales from $10^7$ to $10^9\,\rm{M}_{\odot}$. In this context emerging galaxies see their star formation rate strongly boosted. They become more luminous and metal rich than their counterparts without primordial magnetic fields. Such strong fields are ruled out by their inability to reproduce the observed scaling relations of dwarf galaxies. They predict dwarf galaxies to be at the origin of an unrealistically early reionization of the Universe and also overproduce luminous satellites in the Local Group. Weaker magnetic fields impacting the primordial density field at corresponding masses $\lesssim 10^6\,\rm{M}_{\odot}$, produce a large number of mini dark halos orbiting the dwarfs, however out of reach for current lensing observations. This study allows for the first time to constrain the properties of primordial magnetic fields based on realistic cosmological simulations of dwarf galaxies.

Constructing a ball of separable and absolutely separable states for $2\otimes d$ quantum system
Creators: name: Adhikari, Satyabrata
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Absolute separable states is a kind of separable state that remain separable under the action of any global unitary transformation. These states may or may not have quantum correlation and these correlations can be measured by quantum discord. We find that the absolute separable states are useful in quantum computation even if it contains infinitesimal quantum correlation in it. Thus to search for the class of two-qubit absolute separable states with zero discord, we have derived an upper bound for $Tr(\varrho^{2})$, where $\varrho$ denoting all zero discord states. In general, the upper bound depends on the state under consideration but if the state belong to some particular class of zero discord states then we found that the upper bound is state independent. Later, it is shown that among these particular classes of zero discord states, there exist sub-classes which are absolutely separable. Furthermore, we have derived necessary conditions for the separability of a given qubit-qudit states. Then we used the derived conditions to construct a ball for $2\otimes d$ quantum system described by $Tr(ρ^{2})\leq Tr(X^{2})+2Tr(XZ)+Tr(Z^{2})$, where the $2\otimes d$ quantum system is described by the density operator $ρ$ which can be expressed by block matrices $X,Y$ and $Z$ with $X,Z\geq 0$. In particular, for qubit-qubit system, we show that the newly constructed ball contain larger class of absolute separable states compared to the ball described by $Tr(ρ^{2})\leq \frac{1}{3}$. Lastly, we have derived the necessary condition in terms of purity for the absolute separability of a qubit-qudit system under investigation.

description: This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots. Econometric evidence shows that variety richness increases farm productivity. Variety richness also reduces yield variability but only for high levels of genetic diversity. Simulations with estimated parameters illustrate how planting more diverse durum wheat varieties on multiple plots contributes to improving farmer’s welfare.

description: Modern crop production is based on only a few plant species. Particularly in marginal environments of developing agricultural economies, many less well-known agricultural or non-timber forest species, continue to be grown, managed or collected, thus contributing to the livelihood of the poor and to agricultural biodiversity. Some of these species, called underutilized plant species, are characterized by the fact that they are locally in developing countries but globally rare, that scientific information and knowledge about them is scant, and that their current use is limited relative to their economic potential. In this paper, we first identify the economic factors that cause these plants to be ‘underutilized’. Based on this analysis, we propose a classification of underutilized plant species based on the relationship of the observed to the potential economic value of the species, and the presence or absence of and constraints to output markets. Then, focusing on a subset of underutilized plant species with market potential, we identify three necessary conditions for the successful commercialization of underutilized plant species for the benefit of the poor: demand expansion, increased efficiency of supply and marketing channels, and a supply control mechanism. This conceptual framework is intended to provide a basis for an empirical assessment of marketing solutions for underutilized plant species among the rural poor in developing economies.

The Dynamics of Group Codes: Dual Abelian Group Codes and Systems

Subjects: subject: Information Theory (cs.IT)

subject: E.4; H.1.1

description: Fundamental results concerning the dynamics of abelian group codes (behaviors) and their duals are developed. Duals of sequence spaces over locally compact abelian groups may be defined via Pontryagin duality; dual group codes are orthogonal subgroups of dual sequence spaces. The dual of a complete code or system is finite, and the dual of a Laurent code or system is (anti-)Laurent. If C and C^\perp are dual codes, then the state spaces of C act as the character groups of the state spaces of C^\perp. The controllability properties of C are the observability properties of C^\perp. In particular, C is (strongly) controllable if and only if C^\perp is (strongly) observable, and the controller memory of C is the observer memory of C^\perp. The controller granules of C act as the character groups of the observer granules of C^\perp. Examples of minimal observer-form encoder and syndrome-former constructions are given. Finally, every observer granule of C is an "end-around" controller granule of C.

description: Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and non-agricultural commodities. An agro-economic model, including mean climate variables, was developed to assess irrigation and road construction investment strategies in comparison to a baseline scenario over a 12-year time horizon. The motivation for this work is to evaluate whether the inclusion of climate variability in the model has a significant effect on prospective investment strategies and the resulting country-wide economy. The mean climate model is transformed into a variable climate model by dynamically adding yearly climate-yield factors, which influence agricultural production levels and linkages to non-agricultural goods. Nine sets of variable climate data are processed by the new model to produce an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country’s future welfare by the mean climate model method, in comparison to probability density functions created from the variable climate ensemble. The ensemble is further utilized to demonstrate risk assessment capabilities. The addition of climate variability to the agro-economic model provides a framework, including realistic ranges of economic values, from which Ethiopian planners may make strategic decisions.

description: Changes in India’s seed regulations during the 1990s favored the growth of privately- as compared to publicly-funded sectors. Most advances have been made in the major millet crops, sorghum and pearl millet, as compared to finger millet and other minor millet crops, which in many ways dependent on local markets for seed purposes. In this study, we have analyzed the evolving interactions between formal systems related to the delivery of modern varieties and informal systems for maintaining traditional seeds in the semi-arid regions of India. It is evident that in these marginal environments, crop and variety use decisions, and the crop biodiversity levels take place within the context of local seed markets and a national seed industry. The outcome of the study would help to identify potential entry points for millet crop improvement and related seed system interventions for marginal environments of India.

description: The regulatory approval of genetically modified crops in the field initially requires small, restricted experimental trials known as confined field trials. These small scale experiments provide researchers with important information on environmental interactions and agronomic performance of the crop in a safe and contained manner. To authorize confined field trials regulatory review is required, with formats for obtaining relevant information differing from country to country. In this paper, a Gap Analysis is used to identify informational gaps and potential for harmonization of confined field trial application processes in three East African countries - Tanzania, Kenya, and Uganda. The basic principle behind gap analysis is a comparison of the status quo to an ideal with the identification of the differences or gaps and the difficulty involved in removing the gaps. The resulting similarity of the application forms provides a potential basis for harmonization of confined field trial application processes between countries leading to potential efficiency gains.
BOUNDARY ORGANIZATIONS: AN EFFICIENT STRUCTURE FOR MANAGING KNOWLEDGE IN DECISION-MAKING UNDER UNCERTAINTY

subject: multi-agent system

description: Modern environmental issues imply that decision-makers take into account opinions from experts of different spheres. Boundary organizations are institutions able to cross the gap between different areas of expertise and to act beyond the boundaries while remaining accountable to each side: by encouraging a flow of useful information, they permit an exchange to take place while maintaining the authority of each side, in order to provide a better knowledge and understanding of a situation characterized by uncertainty. Though never formally proved, this hypothesis is widely accepted based on the observation of existing boundary organizations. Through a multi-agent simulation, it is possible to assess their impact on the diffusion of opinions among experts. This virtual interaction of heterogeneous agents based on a model of continuous opinion dynamics over two dimensions, shows that boundary organizations have a significant quantitative impact on the diversity of opinions expressed and the number of experts agreeing to each emerging position.
