description: We present a calculation of the low lying spectrum of a rotating Bose-Einstein condensate. We show that in a cylindrical geometry, there exist two linear branches, one associated to usual acoustic excitation, the other corresponding to a twisting mode of the vortex lattice. Using a hydrodynamical approach we derive the elasticity coefficient of the vortex lattice and calculate the spectrum of condensate in a three dimensionnal harmonic trap with cylindrical symmetry.

description: Reforms in the U.S. peanut program entail a reduction in support price of peanuts. The degree to which price reduction is passed on to final consumers of peanut butter is directly related to the degree of competition in the peanut butter market. To assess the impact of changes in the peanut program on final consumers, it is necessary to know the degree of competition in the peanut butter industry. A dynamic error correction model (ECM) developed by Steen and Salvanes is estimated using nonlinear-three-stage-least-squares procedure to measure the degree of competition. Results indicate that the market is characterized by perfect competition in the short-run. The hypothesis of perfect competition is rejected in the long-run, although the long-run solution is close to a perfectly competitive behavior. This result has important implications for the peanut butter industry. Reductions in the support price of peanut may not be fully passed on to peanut butter consumer, but the consumers' welfare gain will certainly be much higher than what it would have been if the market was collusive in structure.

description: Caffeic acid (CA) is a well-known natural compound used for both health supplement and metabolic diseases. In the present study, single, easy, and quick isolation procedure of caffeic acid was described from rosmarinic acid. A quick crystal formation also was described for highly hygroscopic CA which was spontaneous and stable with lower hygroscopic nature. In addition, the produced crystal CA was highly stable and showed neuroprotective activity with <6 μg/ml in R28 cell line and cytotoxic activity with >100 μg/ml in U87 MG which revealed its dual biological effect for the treatment of Alzheimer’s disease and cancer, respectively.

description: Even if governments agree on equivalency of organic standards across countries, consumers may still believe domestically produced organic foods are superior to imports. We simulated a partial equilibrium model of trade in organic wheat between the United States and Germany to illustrate the welfare gains and losses associated with international harmonization of organic standards. Six cases were examined - no equivalency in standards (the status quo), equivalency of standards with complete and incomplete import acceptance, exporters certifying in importing country with complete and incomplete import acceptance, and exporters paying educational costs, with incomplete import acceptance. Results demonstrate that importing country consumers are better off if they are willing to accept imports as equivalent to domestically produced organic foods. Strategies to reduce resistance such as educational programs or foreign certification add costs to production that reduce quantity traded and impose welfare losses on exporting country producers and importing country consumers.

Currently, people underestimate the importance of medicinal plants and illegally sell them abroad. The golden list of our valuable medicinal wealth includes such plants as golden root, sage, ephedra, mint, Ili barberry, etc. This article discusses the bioecological features, medicinal value and distribution area of Ephedra L. in Zhetysu Alatau
An exploration of types that integrate art with the landscape
Creators: name: Steed, Alexandra Mary
Publisher: name: University of British Columbia
Year: 2009

description: This paper explores various methods of integrating art into the landscape. It is recognized that the landscape is an important location of human experience. Art has the capacity to enhance our understanding of the world as it is concerned with heightening one's perceptions. Thus, it is important that art be integrated into the landscape to illuminate the relationship between humans and the material world. A literature review is conducted in order to determine methods of integrating art with the landscape. First, precedents of art in the landscape, and art and landscape architectural theory, are researched to identify criteria of engaging landscape experience. Second, a typology of differing modes of integrating art and landscape architecture is drawn out of the literature review. In response to the research, a site is chosen and designed according to the types identified. The designs provide a model of various modes of integrating art with the landscape and allow the theory to be tested and evaluated. The conclusion is that there is no right way of integrating art into the environment, but that in certain situations one type may be more appropriate than another. It is recognized that planning for art in the landscape is extremely important to ensuring integration between artwork and landscape. Perhaps then, the typology identified in this paper is best used by public art planners in the pre-development stage. By planning for art in the landscape proactively, there is less opportunity for landscape and artwork to be autonomous and objectified. To be sure, when art is integrated with the landscape the experience of place is enriched, and as a result, the human experience is enhanced.

description: The estimation of covariance matrices of multiple classes with limited training data is a difficult problem. The sample covariance matrix (SCM) is known to perform poorly when the number of variables is large compared to the available number of samples. In order to reduce the mean squared error (MSE) of the SCM, regularized (shrinkage) SCM estimators are often used. In this work, we consider regularized SCM (RSCM) estimators for multiclass problems that couple together two different target matrices for regularization: the pooled (average) SCM of the classes and the scaled identity matrix. Regularization toward the pooled SCM is beneficial when the population covariances are similar, whereas regularization toward the identity matrix guarantees that the estimators are positive definite. We derive the MSE optimal tuning parameters for the estimators as well as propose a method for their estimation under the assumption that the class populations follow (unspecified) elliptical distributions with finite fourth-order moments. The MSE performance of the proposed coupled RSCMs are evaluated with simulations and in a regularized discriminant analysis (RDA) classification set-up on real data. The results based on three different real data sets indicate comparable performance to cross-validation but with a significant speed-up in computation time.

description: We present an attempt to formulate the supersymmetric and relativistic quantum mechanics in the sense of realizing supersymmetry on the single particle level, by utilizing the equations of motion which is equivalent to the ordinary 2nd quantization of the chiral multiplet. The matrix formulation is used to express the operators such as supersymmtry generators and fields of the chiral multiplets. We realize supersymmetry prior to filling the Dirac sea.

description: The formation of DNA loops by proteins and protein complexes that bind at distal DNA sites plays a central role in many cellular processes, such as transcription, recombination, and replication. Here we review the basic thermodynamic concepts underlying the assembly of macromolecular complexes on looped DNA and the effects that this process has in the properties of gene regulation. Beyond the traditional view of DNA looping as a mechanism to increase the affinity of regulatory molecules for their cognate sites, recent developments indicate that DNA looping can also lead to the suppression of cell-to-cell variability, the control of transcriptional noise, and the activation of cooperative interactions on demand.

description: As annotations of data can be scarce in large-scale practical problems, leveraging unlabelled examples is one of the most important aspects of machine learning. This is the aim of semi-supervised learning. To benefit from the access to unlabelled data, it is natural to diffuse smoothly knowledge of labelled data to unlabelled one. This induces to the use of Laplacian regularization. Yet, current implementations of Laplacian regularization suffer from several drawbacks, notably the well-known curse of dimensionality. In this paper, we provide a statistical analysis to overcome those issues, and unveil a large body of spectral filtering methods that exhibit desirable behaviors. They are implemented through (reproducing) kernel methods, for which we provide realistic computational guidelines in order to make our method usable with large amounts of data.

description: Black hole spontaneous scalarization has been attracting more and more attention as it circumvents the well-known no-hair theorems. In this work, we study the scalarization in Einstein-scalar-Gauss-Bonnet theory with a probe scalar field in a black hole background with different curvatures. We first probe the signal of black hole scalarization with positive curvature in different spacetimes. The scalar field in AdS spacetime could be formed easier than that in flat case. Then, we investigate the scalar field around AdS black holes with negative and zero curvatures. Comparing with negative and zero cases, the scalar field near AdS black hole with positive curvature could be much easier to emerge. And in negative curvature case, the scalar field is the most difficult to be bounded near the horizon.

description: We comment on the recent suggestion to use a family of local uncertainty relations as a standard way of quantifying entanglement in two-qubit systems. Some statements made on the applicability of the proposed "measures" are overly optimistic. We exemplify how these specific "measures" fall short, and present a minor modification of the general theory which uses the same experimentally gathered information, but in a slightly different, better way.

General Coordinate Transformations as the Origins of Dark Energy

description: In this note we demonstrate that the algebra associated with coordinate transformations might contain the origins of a scalar field that can behave as an inflaton and/or a source for dark energy. We will call this particular scalar field the diffeomorphism scalar field. In one dimension, the algebra of coordinate transformations is the Virasoro algebra while the algebra of gauge transformations is the Kac-Moody algebra. An interesting representation of these algebras corresponds to certain field theories that have meaning in any dimension. In particular the so called Kac-Moody sector corresponds to Yang-Mills theories and the Virasoro sector corresponds to the diffeomorphism field theory that contains the scalar field and a rank-two symmetric, traceless tensor. We will focus on the contributions of the diffeomorphism scalar field to cosmology. We show that this scalar field can, qualitatively, act as a phantom dark energy, an inflaton, a dark matter source, and the cosmological constant Lambda.
Global analyses of BSM theories using LHC Run 2
Creators: name: Costa, Jonathan Cristiano
Publisher: name: Imperial College London
Year: 2019

description: The work presented in this thesis explores the experimental, phenomenological, astrophysical and cosmological constraints on SUSY models with three distinguished input scales. The SUSY SU(5) GUT model assumes the soft SUSY-breaking parameters to be universal at the GUT scale $M_{\mathrm{GUT}}$. In the Phenomenological MSSM with eleven parameters (pMSSM11), the input parameters are specified at the $\msusy \equiv \sqrt{\mst1 \mst2}$ scale, which is also the scale at which electroweak symmetry breaking conditions are imposed. In the sub-GUT MSSM, the universality of the input parameters is imposed at some input scale $M_{\mathrm{in}}$ below $M_{\mathrm{GUT}}$ but above the electroweak scale. In addition to the SUSY models, this work also includes a global analysis of Dark Matter Simplified Models (DMSMs) with leptophobic spin-one mediator particles with either vectorial or axial couplings to Standard Model (SM) particles and the dark matter (DM) particle. The {\tt MasterCode} tool is used to analyse the constraints on the parameter spaces of each model, taking into account the relevant searches from up to 139/fb of LHC data at $\sqrt{s}=$~13 TeV, and the most recent limits from the LUX, PICO, XENON1T and PandaX-II experiments. Other experimental constraints are also taken into account (when applicable), including those from flavour physics, electroweak precision observables, the anomalous magnetic dipole momentum of the muon, and cosmological constraints on the DM relic density. The DM annihilation mechanisms responsible for bringing the relic density into the allowed region are identified in the preferred regions of the parameter spaces.
Assessing the impacts of land-use change on the hydrology of the tropical Andes
Creators: name: Chou, Hsi-Kai
Publisher: name: Imperial College London
Year: 2019

description: Land-use and land-cover change (LUCC) has been identified as a major driver of change to the hydrological cycle. However, it is still a scientific challenge to quantify these effects. Land surface models are increasingly being used for such hydrological assessment because of their state-of-the-art representation of physical processes and versatility. A physically-based model has the advantage to map the modeller’s knowledge about the hydrological impacts of land-use and land-cover change into physically meaningful parameters. This PhD thesis explores the use of a land surface model (Joint UK Land-Environment Simulator, JULES) in combination with high temporal resolution in-situ data on streamflow, precipitation, and several weather variables, collected by a grassroots hydrological monitoring initiative (called iMHEA) in the tropical Andes. I find that the in-situ data can improve the hydrological simulation substantially, mainly by reducing uncertainty inherent in using large-scale precipitation data. The commonly used soil parameters based on pedotransfer functions lead to an underestimation of the flow. Therefore, I modified the soil parameterisation with experimental data for a more accurate representation of subsurface flow generation. Subsequently, I assessed the potential impacts of watershed interventions (grazing, afforestation, cultivation) using the calibrated soil parameters. A reduction in water yield and water regulation ability under these land use scenarios was identified, which is in line with observed impacts and relevant for water resources managers. In a next step, I implemented an open source land use change model, the lulcc R package, to analyse the regional land cover changes in the Andean region, and to generate predictive land use maps that can be used to drive the JULES model. For this purpose, the JULES model has been implemented at a regional scale using multiple sources of global data. The use of the JULES model allows the effects of LUCC to be assessed using knowledge about physical processes. My results show a further 3.7% of deforestation occurring in the region, which changes the flow by ±17% consequently.

description: Full quantum dynamics calculations have been carried out for the ionic reaction 4He2+ + 3He and state-to-state reactive probabilities have been obtained using both a time-dependent (TD) and a time-independent (TI) approach. An accurate ab-initio potential energy surface has been employed for the present quantum dynamics and the two sets of results are shown to be in agreement with each other. The results for zero total angular momentum suggest a marked presence of atom exchange (isotopic replacement) reaction with probabilities as high as 60%. The reaction probabilities are only weakly dependent on the initial vibrational state of the reactants while they are slightly more sensitive to the degree of rotational excitation. A brief discussion of the results for selected higher total angular momentum values is also presented, while the l-shifting approximation [1] has been used to provide estimates of the total reaction rates for the title process. Such rates are found to be large enough to possibly become experimentally accessible.
Different roles of nodes in networks
Creators: name: Yao, Qing
Publisher: name: Imperial College London
Year: 2019

description: The 'complex network' has been studied in many disciplines. In this thesis, we use an economic network to study the heterogeneity of the networks. Networks of shareholders in Turkey and the Netherlands are constructed from raw data. The nodes are shareholders and an edge between shareholders exists if they have invested in the same company. The general analysis of network has shown that this type of network has characteristics similar to other types of real-world networks: power-law like degree distributions, small-world phenomenon and scaling of community size distributions. Furthermore, we introduce the 'type' of shareholders and analyse the different behaviour of shareholder types by comparing with a randomised null model. The results are that different types of shareholders are parts of different topological structures in the networks. Based on the economic behaviours, we propose a random walk model to mimic the different roles of shareholders in the networks. The model starts with a directed random graph of shareholders with assigned labels/types mimicing the raw data, and companies, showing which companies shareholders have invested in. A biased random walker model is introduced to model, on an abstract level, how shareholders' investments evolve. We then extract the associated shareholder network. This evolving model can qualitatively explain general characteristics and heterogeneity of the real-world shareholder networks: the scaling of community size distributions, percolation behaviour and the average shortest paths between different types. When we focus on the emergence of features from local interactions and higher-order interactions. We propose a new framework for this analysis. For a more general analysis, we design a simple transition matrix of temporal triplets. By comparing the transition matrix of higher-order interactions with the transition matrix of a pairwise interaction toy model, we can quantify the interactions of triplets. Moreover, we create an algorithm based on the transition matrix to make link predictions. We apply this framework to real-world networks and show that this new framework is successful in making predictions.

description: The study presented here applied systems thinking to the context of Jordan to assess the wider factors and potential misalignments affecting teacher management in the country. The study was conducted by a team of researchers from New York University-TIES and the Queen Rania Foundation (QRF) in Jordan as part of the Education Research in Conflict and Protracted Crisis (ERICC) Research Programme Consortium (referred to in this report as the ERICC team).The ERICC team set out to apply the RISE Diagnostic Framework to the case of Jordan’s education sector, ultimately adapting and applying the tool to identify and prioritise misalignments within the country’s teacher management system. In doing so, the RISE Diagnostic Framework helped the ERICC team to map the varying purposes for which different parts of the teacher management system were aligned.The RISE Framework proposes that education systems consist of four key relationships of accountability between different principals and agents: Compact (Relationship between the highest authorities of the state and education authorities including the Ministry of Education, or MoE); Management (Relationship between the education authorities and frontline providers of education i.e., schools, principals, teachers); Voice and Choice (Relationship between frontline providers of services and recipients of services); and Politics (Relationship between citizens and the highest authorities of the state). Of these relationships, the study was limited to examining the first two relationships, Compact and Management, in the context of teacher management in Jordan.Based on the RISE diagnostic analysis, the ERICC team finds that Jordan’s teacher management system appears to be primarily aligned for access and process compliance, with pockets of stakeholders attempting to bring greater focus on, and alignment for, learning outcomes. Seven misalignments are identified, primarily within the Management relationship. In addition, the team identifies three recommendations and considerations for future applications of the diagnostic in conflict-affected contexts: (1) limited accessibility and interpretation challenges of MoE policies and the invisibility of policies related to refugees’ education provision; (2) the tool likely requires additional piloting in order to operationalise best practices; and (3) a system-wide diagnostic has tension between inclusivity of minorities and overall influence within the system.

description: We study the dnamics of small magnetic cantilevers, either made from Si covered by a magnetic film or entirely ferromagnetic ones. The magnetomechanical torques are found to cause line splittings in ferromagnetic resonance spectra and magnetization reversal facilitated by mechanical degrees of freedom. We show that the magnetomechanical torques can extend the limits of detecting and exciting motion at the nanoscale. A "nanomotor" described here effectively transforms rf magnetic fields into mechanical oscillations. We furthermore propose to integrate mechanical oscillators into magnetoelectronic devices that make use of current-induced spin-transfer torques. This opens new possibilities for electric transducers of nanomechanical motion.

description: Biologists now engineer transgenic crop varieties that express proteins that are toxic to a variety of common agricultural pests. These transgenic crops offer farmers a new tool for effectively managing pests that reduce yields and increase production costs. However, the concern over pest resistance to these toxins has prompted the EPA to require resistance management plans. Seed companies have focused on a high-does refuge plan where farmers are required to plant a constant proportion of cropland in refuge in order to maintain a susceptible pest population. Currently, entomologists recommend 20 to 40% refuge. This paper develops an economic model of pest management with pest resistance to estimate the constant proportion of refuge that maximizes farm income over a fixed planning horizon. Results indicate that there is a clear economic tradeoff between the pest control and population management benefits afforded by a transgenic variety and the resistance management benefits and savings in production costs afforded by refuge. Under certain circumstance a 20 to 40% refuge is economically sensible. However, the optimal proportion of refuge is sensitive to a number of uncertain biological factors: the initial frequency of resistant pests, and the survival rate of resistant and susceptible pests. Additionally, we find that when the pest population and resistance develop slowly, the economic losses of a suboptimal proportion of refuge are relatively small; however, the biological consequences in terms of pest susceptibility are very large.
Palladium-catalysed carbon-fluorine bond activation of fluoroarenes

Publisher: name: Imperial College London
Year: 2019

description: This thesis focuses on transforming ‘inert’ C–F bonds in readily available fluorocarbons, specifically fluoroarenes, into reactive C–Al bonds. This is a new chemical transformation which we have named “C–F alumination”. In recent years, C–F bond borylation reactions (i.e. the transformation of C–F to C–B bonds) have been developed to generate reactive synthetic building blocks. Each study published has their own advantages and limitations, therefore, the C–F bond alumination protocol reported herein not only addresses some of these limitations, such as high catalyst loading, it also expands the number of catalytic procedures capable of selectively activating C–F bonds and provides a new entry point to organoaluminiums, known to be versatile intermediates in chemical manufacture. In Chapter one, the state of the art methods for the functionalisation of C–F bonds with main group reagents is presented, this literature analysis is centred on methods that generate reactive chemical building blocks such as organoboranes and organosilanes from fluorocarbons. In Chapter two, the serendipitous discovery of a new palladium catalyst for C–F alumination is reported along with the reaction scope and selectivity for a series of pentafluorobiphenyls and tetrafluorobiphenyls. In Chapter three, the substrate scope is then extended to fluorinated monoarenes, followed by preliminary results on an application of the organoaluminium products in carbon–carbon bond formation by cross-coupling. Finally, in Chapter 4 the plausible mechanisms for sp2C–F and sp2C–H alumination are discussed in detail. Both the chemo and regioselectivity are rationalised and insight is provided into the nature and reactivity of the active catalyst and potential catalyst deactivation pathways.

Non structural flood mitigation in Canada : linking the resources of today with a strategy for tomorrow

description: Flooding poses one of the greatest natural hazard dangers to Canadians. As human populations increase and concentrate in areas vulnerable to floods, and uncertainty about future flood risk increases with the possibility of a changing climate, major urban communities, coastal settlements and communities located within floodplains are faced with an even greater risk of floods in the coming years. Canada's policies and practices towards flood control are best described as ad hoc, and have developed over the years in response to experiences with floods. No national scale flood damage reduction program exists, and there is currently no opportunity for Canadian homeowners to purchase flood insurance. This study specifically examines how a national mitigation strategy, focused mainly on non structural techniques could help decrease damages from floods in Canadian communities. The strategy proposed here is theoretically based in EPC and IBC suggestions for a greater national mitigation strategy, as well as IDNDR research, and federal, provincial and municipal goals for sustainable development and sound land use planning objectives. Ideally, a successful non structural flood mitigation strategy for Canada would address issues at the national scale, yet be implementable at the local level in accordance with community needs, risk characteristics, and local expertise. The strategy proposed here would maximize the efficiency of federal resources and private industry as well as allow local expertise and existing mitigation schemes to be formalized, bolstered and improved. There are three major components of the non structural flood mitigation strategy. Risk avoidance measures such as early warning systems, land use and resource planning and ecological conservation all work towards reducing the chances of a dangerous flood occurring. Risk spreading measures help communities deal with flood risks by improving equity and accountability, they include tax incentives, disaster financial assistance, and flood insurance. Lastly, vulnerability reduction measures help reduce damages if a flood were to strike, and these include enforcement of building codes and the maintenance of existing protective infrastructure. An integrated, non structural flood mitigation strategy would require basin-wide cooperation between all levels of government, citizens and the private sector. This strategy is also an opportunity for communities and individuals to meet goals of environmental conservation and sustainable development. The focus in this study lies on the mitigation tools, although it is the overall process of inserting the premise of mitigation into all land use and planning decision making processes that will be the key to successful flood mitigation strategies in Canadian communities.
Depression screening practices of prenatal genetic counselors

description: Prenatal depression is a common problem for pregnant women, affecting up to 15% of women with even higher rates in low-income countries, and can have negative effects on the health and wellbeing of both mother and child. Women referred to a prenatal genetic counselor may be experiencing stressors such as an increased risk of aneuploidy, and may need to make important, time-sensitive decisions regarding their pregnancy. It is well established that depression can negatively impact the decision-making process, and the American College of Obstetricians and Gynecologists (ACOG) recommends that all healthcare providers perform depression screening for patients during the prenatal period. Therefore, we examined the methods prenatal genetic counselors are using to assess for depression in their patients as well as their opinions on this topic.We found that while 60.0% of respondents believe addressing depression in the context of the prenatal genetic counseling session is important, only 30.4% routinely do so. This suggests the existence of barriers that may be hindering some genetic counselors from obtaining this information from patients. These barriers include the social stigmatization of openly discussing mental health, discomfort on the part of the patient, and a lack of time in the counseling session. Additionally, only 53.2% of respondents feel confident in their abilities to identify and address symptoms of depression in a patient, and only 36.2% are aware of the ACOG guidelines regarding depression screening. Awareness of the ACOG guidelines was found to be significantly correlated with confidence in one’s ability to address depression, and likelihood to discuss protective mental health factors with patients. These results indicate the need for more education and awareness regarding the utility and necessity of depression screening in the prenatal genetics setting.

description: The value of soil-test information in planning fertilizer application levels is determined by using agricultural field-plot data to estimate the posterior distribution of mean soil-nitrate concentrations at a give location. Optimal decisions concerning fertilizer application levels are made with respect to this posterior distribution. Average reductions in fertilizer application rates range from 15 to 41 percent, depending on the form of prior information that is available. These reductions are achieved by increasing the variability of application rates over time. Disregarding the uncertainty that remains after the soil testing significantly overstates the expected benefits of soil testing.

description: We study unitary random matrix ensembles of the form $Z_{n,N}^{-1} |\det M|^{2α} e^{-N \Tr V(M)}dM$, where $α>-1/2$ and $V$ is such that the limiting mean eigenvalue density for $n,N\to\infty$ and $n/N\to 1$ vanishes quadratically at the origin. In order to compute the double scaling limits of the eigenvalue correlation kernel near the origin, we use the Deift/Zhou steepest descent method applied to the Riemann-Hilbert problem for orthogonal polynomials on the real line with respect to the weight $|x|^{2α}e^{-NV(x)}$. Here the main focus is on the construction of a local parametrix near the origin with $ψ$-functions associated with a special solution $q_α$ of the Painlevé II equation $q''=sq+2q^3-α$. We show that $q_α$ has no real poles for $α> -1/2$, by proving the solvability of the corresponding Riemann-Hilbert problem. We also show that the asymptotics of the recurrence coefficients of the orthogonal polynomials can be expressed in terms of $q_α$ in the double scaling limit.

description: New production technologies, consumers who are more discriminating, and the need for improved coordination are among the forces driving the move from spot markets to contracts. Some worry that this tendency will result in the disappearance of spot markets, or at least that they will become too thin to be of help for an efficient price discovery process. Other authors point to the reduction in welfare of independent producers resulting from contracting in oligopsonistic industries. While a large body of literature is available tackling the contract versus spot market decision, much less is known about the reasons that lead to procurement in both markets. This paper provides a simple model to study how fundamental economic factors influence the contracting behavior of farmers and processors. In the model, processors contract upstream with price-taking farmers. Participation in both markets arises as a Nash equilibrium for a wide range of parameterizations. Numerical methods are used to examine the effects of fundamental economic factors on the relative size of the spot and contract markets.
