description: Given the search for recovery processes that are more efficient with lower water consumption and greenhouse gas emissions than Steam-Assisted Gravity Drainage (SAGD), solvent based recovery processes are a potential alternative. Vapor Extraction (VAPEX) and N-SolvTM are two potentially competing solvent recovery processes that offer water-free operation. Although VAPEX has demonstrated success in laboratory experiments, it has not been demonstrated to be technically or commercially successful in the field due to the slow oil production rate. To improve oil recovery rate over that of VAPEX, the N-SolvTM process injects heated solvent into the reservoir to provide additional energy to the reservoir which enhances the reduction of the oil phase viscosity beyond that of solvent alone. The heated solvent is injected at pressures under its vapor pressure (at injection temperature) to ensure it is vapor. At the chamber interface, the solvent condenses releasing latent heat to the oil sand. Condensed solvent diffuses into bitumen and dilutes it reducing its viscosity to achieve mobility and drainage of the oil to the production well under the action of gravity. In the research documented here, the mechanisms and effectiveness of the N-SolvTM process in a McMurray oil sand reservoir is investigated by fine grid (8 cm by 8 cm grid blocks in the cross well pair plane) thermal reservoir simulation. A sensitivity analysis of the N-SolvTM process was also done to explore possible ways to enhance oil production and reducing solvent retention in the depleted reservoir. iii The results reveal that dynamics at the edge of the chamber – including phase change, oil viscosity reduction by elevated temperature and solvent diffusion, and the interaction between heat and mass transfer are complex. Also, in a dead oil reservoir, the injection of hot propane into oil sands reservoirs can yield comparable oil production rates to that of SAGD. Furthermore, solvent loss, which is a major concern, can be reduced by injecting at superheated conditions and relatively low pressures. Lastly, in the presence of solution gas and high connate water saturation in the reservoir, the performance of N-SolvTM suffers significantly.

description: The purpose of this study was to reveal how Canadian foreign correspondents constructed a Canadian perspective in their reports on key Cold War conflicts. Four Cold War conflicts and four correspondents were selected; The Suez Crisis (1956) as reported by Peter Worthington for The (Toronto) Telegram; erection of the Berlin Wall (1961) as reported by Stanley Burke for CBC Television; the Vietnam War (1971-73) as reported by Joe Schlesinger for CBC Television; Nicaragua’s civil war (1981-1984) as reported by Oakland Ross for The Globe and Mail. With the application of critical discourse analysis the reportage revealed that there was a common, unspoken, Canadian perspective or sensibility expressed by the correspondents. Most of their reports focus on people who are victimized by the clashes between the super powers. They dwell on the people who are caught in the middle of violent Cold War conflicts over which they have very little control. Analysis also revealed that except for Worthington’s reports from The Suez Zone in 1957-58, the mention of Canada or Canadians is rare, as is the posturing by the Soviet Union and the United States, posturing that sometimes threatened to break out into nuclear war. Instead, these Canadian correspondents were more concerned about the hapless men, women and children, caught in the crossfire of the proxy wars fought by the Soviet Union, the United States, and China. Although interviews with correspondents revealed that they hadn’t given much thought to what a Canadian perspective would entail, the perspective in their reportage reflects Canada’s history and identity as a country that values surviving rather than domination. It also reflects Canada’s history as a country that often found itself caught between the demands of two super-powers – Britain and the United States. During the Cold War federal leaders sought to carve out a role for Canada in which it sought common ground with smaller nations rather than become completely subservient to the demands of its key ally – the United States. This public shunning of the U.S. is another key theme in the reports of the four foreign correspondents.

description: The taxonomy of soil erosion presented here delineates land resources with high potential for erosion control . More than one-third of U.S. cropland is inherently nonerosive under all management regimes, about half requires conservation management to keep soil loss within tolerable limits, and the remaining 8 percent is so erosive that acceptable soil loss rates cannot be achieved under intensive cultivation. Nationally, no statistically important relationships were found between characteristics of farm owner-operators and erosiveness of cropland.

description: Multi-satellite, multi-modality in-orbit fusion is a challenging task as it explores the fusion representation of complex high-dimensional data under limited computational resources. Deep neural networks can reveal the underlying distribution of multi-modal remote sensing data, but the in-orbit fusion of multimodal data is more difficult because of the limitations of different sensor imaging characteristics, especially when the multimodal data follows non-independent identically distribution (Non-IID) distributions. To address this problem while maintaining classification performance, this paper proposes a manifold-driven multi-modality fusion framework, FedFusion, which randomly samples local data on each client to jointly estimate the prominent manifold structure of shallow features of each client and explicitly compresses the feature matrices into a low-rank subspace through cascading and additive approaches, which is used as the feature input of the subsequent classifier. Considering the physical space limitations of the satellite constellation, we developed a multimodal federated learning module designed specifically for manifold data in a deep latent space. This module achieves iterative updating of the sub-network parameters of each client through global weighted averaging, constructing a framework that can represent compact representations of each client. The proposed framework surpasses existing methods in terms of performance on three multimodal datasets, achieving a classification average accuracy of 94.35$\%$ while compressing communication costs by a factor of 4. Furthermore, extensive numerical evaluations of real-world satellite images were conducted on the orbiting edge computing architecture based on Jetson TX2 industrial modules, which demonstrated that FedFusion significantly reduced training time by 48.4 minutes (15.18%) while optimizing accuracy.}
The role of Pyk2 and FAK in B cell migration, adhesion, and spreading
Creators: name: Tse, Kathy Wan-Kei
Publisher: name: University of British Columbia
Year: 2010

description: The ability of the B cell receptor (BCR) to stimulate integrin-mediated adhesion, and induce cytoskeletal reorganization and cell spreading enhances the ability of B cells to bind and respond to antigens (Ag). The proper localization and trafficking of B cells in the secondary lymphoid organs are also critical for B cells to encounter Ags and to be activated. Proline-rich tyrosine kinase (Pyk2) and focal adhesion kinase (FAK) are related cytoplasmic tyrosine kinases that have been shown to regulate cell adhesion, morphology, and migration. However, their functions in B cells are not clear. The overall hypothesis of this thesis was that Pyk2 and FAK are downstream targets of BCR, integrin, and chemokine receptor signaling, and that they are involved in B cell morphological regulation, migration, and adhesion. I showed that the BCR and integrins collaborate to induce the phosphorylation of Pyk2 and FAK on key tyrosine residues, modifications that increase the kinase activity of Pyk2 and FAK. Activation of the Rap1 GTPase is critical for BCR-induced integrin activation and for BCR-induced reorganization of the actin cytoskeleton and I showed that inhibition of Pyk2 and FAK function by either gene knockdown or the use of chemical inhibitors impaired B cell spreading. Marginal zone (MZ) B cells are innate-like B cells that are responsible for T cell-independent responses to microbial pathogens. The proper localization of MZ B cells is dependent on integrated migration and retention signals provided by the stromal cells in the spleen. Because MZ B cells are not found in Pyk2-/- mice, I hypothesized that Pyk2 and FAK are involved in MZ B cell retention in the spleen. I showed that Pyk2 and FAK are required for MZ B cell migration and that Pyk2 is required for integrin-dependent adhesion in response to chemoattractant stimulation. Moreover, I found that FAK is involved in chemokine-induced Akt phosphorylation in MZ B cells. In summary, Pyk2 and FAK are downstream targets of the Rap GTPases and play a key role in regulating B cell morphology, migration, and adhesion.

The dark matter story passed through several stages from a minor observational puzzle to a major challenge for theory of elementary particles. Modern data suggest that dark matter is the dominant matter component in the Universe, and that it consists of some unknown non-baryonic particles. Properties of dark matter particles determine the structure of the cosmic web.

description: We investigate the thermodynamic and transport properties of molybdenum-doped BaFe2As2 (122) crystals, the first report of hole doping using a 4d element. The chemical substitution of Mo in place of Fe is possible up to ~ 7%. For Ba(Fe1-xMox)2As2, the suppression rate of the magnetic transition temperature with x is the same as in 3d Cr-doped 122 and is independent of the unit cell changes. This illustrates that temperature-composition phase diagram for hole-doped 122 can be simply parameterized by x, similar to the electron-doped 122 systems found in literature. Compared to 122 with a coupled antiferromagnetic order (TN) and orthorhombic structural transition (To) at ~ 132 K, 1.3% Mo-doped 122 (x = 0.013) gives TN = To = 125(1) K according to neutron diffraction results and features in specific heat, magnetic susceptibility and electrical resistivity. The cell volume expands by ~ 1% with maximum Mo-doping and TN is reduced to ~ 90 K. There is a new T* feature that is identified for lightly Cr- or Mo-doped (< 3%) 122 crystals, which is x dependent. This low-temperature transition may be a trace of superconductivity or it may have another electronic or magnetic origin.

description: Organoscandium complexes supported by four different ancillary ligand frameworks were studied in the context of developing catalysts for CO2 hydrosilation. These include known B-diketiminate supported bis-alkyls, as well as novel anilido-imine and anilido-pyridine based scandium alkyls, incorporating previously published ligand frameworks. A new anilido-bypyridyl ligand set was designed and synthesized, based on insights garnered from studying the previous systems. For each system, a survey of reactivity with CO2 was undertaken, followed by a study of their activity as catalysts for CO2 hydrosilation, using trialkylsilanes as reductants and a B(C6F5)3 co-catalyst. In all cases, facile insertions into alkyl-scandium bonds were observed, to give isolable carboxylate complexes. In the case of the B-diketiminate systems, exposure to an excess of CO2 led to transannular addition of a third equivalent of CO2 into the ligand framework, leading to ligand decoordination. A cationic complex was formed by abstraction of acetate with B(C6F5)3, which was found to active for CO2 hydrosilation to methane. The carboxylate complexes of the anilido-imine and anilido-pyridine based complexes underwent no further deleterious reactivity when exposed to excess CO2. For the latter, L2ScR type carboxylates were preferentially formed, and generation of reactive cations was accomplished by addition of B(C6F5)3 and trialkylsilane, forming a silyl-ester adduct with hydridoborate counter anion. This ion pair was catalytically active, accomplishing ~85 turnovers in a period of 13 hours, however the catalytic activity was eventually quenched, likely due to the buildup of the bis-silyl acetal hydrosilation product which barred the approach and activation of CO2 at the metal center. The anilido-bypyridine system was designed to be inert towards CO2 after ligation, but to preserve the favourable steric and electronic properties of the _-diketiminate framework. Three increasingly sterically demanding derivatives were prepared and installed on scandium. The bulkiest of these incorporated a pendant 3,5-di-tert-butylphenyl group, which underwent metallative C-H bond activation to form a dianionic tetradentate ligand. It was found to be a robust catalyst for CO2 hydrosilation, giving unprecendented selectivity for the bis-silyl acetal product. The mechanism of the conversion was studied, and was shown to involve alternating shuttling of borane and silylium across a coordinatively labile carboxylate group.

description: The irreversibility of a stationary time series can be quantified using the Kullback-Leibler divergence (KLD) between the probability to observe the series and the probability to observe the time-reversed series. Moreover, this KLD is a tool to estimate entropy production from stationary trajectories since it gives a lower bound to the entropy production of the physical process generating the series. In this paper we introduce analytical and numerical techniques to estimate the KLD between time series generated by several stochastic dynamics with a finite number of states. We examine the accuracy of our estimators for a specific example, a discrete flashing ratchet, and investigate how close is the KLD to the entropy production depending on the number of degrees of freedom of the system that are sampled in the trajectories.

La métamorphose du théâtre aristotélicien : Lope de Vega et Pierre Corneille

Publisher: name: Graduate Studies
Year: 2014
Subjects: subject: Literature--Comparative
subject: theatre

description: Lope de Vega and Pierre Corneille are both famous playwrights from the seventeenth-century, one from Spain and the other from France, respectively. This work looks at the differences and similarities in their dramatic theories and the applications of those theories. More specifically, it concentrates on the foundation of their dramatic theories: Aristotle’s Poetics as presented through the work of Francesco Robortello, a sixteenth-century Italian humanist. Since Aristotle was seen as the dramatic authority of the sixteenth and seventeenth century, it is not surprising that his ideas dominated the dramatic theory of the period. However, Robortello’s text was not a direct translation of Aristotle; it was a translation accompanied by commentaries and extrapolations. Therefore, by analyzing the influence of Robortello’s work in the texts of Lope and Corneille, in addition to the modifications Robortello made to the original Aristotelian ideas found in the Poetics, this thesis seeks to find a possible metamorphosis of Aristotelian theatre.

description: A small number of laser-cooled ions trapped in a linear radiofrequency multipole trap forms a hollow tube structure. We have studied, by means of molecular dynamics simulations, the structural transition from a double ring to a single ring of ions. We show that the single-ring configuration has the advantage to inhibit the thermal transfer from the rf-excited radial components of the motion to the axial component, allowing to reach the Doppler limit temperature along the direction of the trap axis. Once cooled in this particular configuration, the ions experience an angular dependency of the confinement if the local adiabaticity parameter exceeds the empirical limit. Bunching of the ion structures can then be observed and an analytic expression is proposed to take into account for this behaviour.

description: This dissertation was based on a research study that sought to understand the experiences and needs of beginning early childhood educators in British Columbia. Utilizing a mixed methods approach, the research involved 114 beginning educators who took part in an online questionnaire, eleven of whom also participated in semi-structured interviews with the researcher. The quantitative data were analyzed using SPSS software, while the qualitative data were analyzed using a process of coding. The key findings were: the work is both overwhelming and deeply satisfying; the induction support beginning early childhood educators receive in British Columbia is haphazard; and beginning early childhood educators in British Columbia would like induction support in the form of mentoring or peer support, observations, feedback, and professional development. A model of best practice for induction support is presented, with recommendations for all stakeholders in the early childhood education field.

description: The possibility of the Lyβ fluorescence mechanism being operational in classical Be stars and thereby contributing to the strength of the OI 8446 Å line has been recognized for long. However this supposition needs to be quantified by comparing observed and predicted OI line ratios. In the present work, optical and near-infrared spectra of classical Be stars are presented. We analyse the observed strengths of the OI 7774, 8446, 11287 and 13165 Å lines which have been theoretically proposed as diagnostics for identifying the excitation mechanism. We have considered and examined the effects of Lyβ fluorescence, collisional excitation, recombination and continuum fluorescence on these OI line strengths. From our analysis it appears that the Lyβ fluorescence process is indeed operative in Be stars.

Distributed Representation of Geometrically Correlated Images with Compressed Linear Measurements

description: This paper addresses the problem of distributed coding of images whose correlation is driven by the motion of objects or positioning of the vision sensors. It concentrates on the problem where images are encoded with compressed linear measurements. We propose a geometry-based correlation model in order to describe the common information in pairs of images. We assume that the constitutive components of natural images can be captured by visual features that undergo local transformations (e.g., translation) in different images. We first identify prominent visual features by computing a sparse approximation of a reference image with a dictionary of geometric basis functions. We then pose a regularized optimization problem to estimate the corresponding features in correlated images given by quantized linear measurements. The estimated features have to comply with the compressed information and to represent consistent transformation between images. The correlation model is given by the relative geometric transformations between corresponding features. We then propose an efficient joint decoding algorithm that estimates the compressed images such that they stay consistent with both the quantized measurements and the correlation model. Experimental results show that the proposed algorithm effectively estimates the correlation between images in multi-view datasets. In addition, the proposed algorithm provides effective decoding performance that compares advantageously to independent coding solutions as well as state-of-the-art distributed coding schemes based on disparity learning.

description: We construct explicitly all extremal instanton solutions to $\mathcal{N}=4,\, D=4$ supergravity truncated to one vector field (Einstein-Maxwell-dilaton-axion (EMDA) theory). These correspond to null geodesics of the target space of the sigma-model $G/H=Sp(4,\mathbb{R})/GL(2,\mathbb{R})$ obtained by compactification of four-dimensional Euclidean EMDA on a circle. They satisfy a no-force condition in terms of the asymptotic charges and part of them (corresponding to nilpotent orbits of the $Sp(4,\mathbb{R})$ U-duality) are presumably supersymmetric. The space of finite action solutions is found to be unexpectedly large and includes, besides the Euclidean versions of known Lorentzian solutions, a number of new asymptotically locally flat (ALF) instantons endowed with electric, magnetic, dilaton and axion charges. We also describe new classes of charged asymptotically locally Euclidean (ALE) instantons as well as some exceptional solutions. Our classification scheme is based on the algebraic classification of matrix generators according to their rank, according to the nature of the charge vectors and according to the number of independent harmonic functions with unequal charges. Besides the nilpotent orbits of $G$, we find solutions which satisfy the asymptotic no-force condition, but are not supersymmetric. The renormalized on-shell action for instantons is calculated using the method of matched background subtraction.

description: In this work, I develop a 1D finite-difference formulation that is capable of simulating non-welded contact boundary conditions in anelastic media. I include, in the linear-slip boundary conditions for non-welded contact, the memory variables that are obtained as a result of considering a generalized Maxwell rheology. Then I proceed to obtain a heterogeneous formulation which is a result of the introduction of a fictitious points scheme for the boundary conditions. In other words I obtain a generalized homogeneous formulation. I solve the resulting system of equations and substitute the amplitudes obtained into the equation of motion. I analyze the numerical results obtained and compare these with an analytical solution and two other anelastic formulations for the welded contact case. I examine different scenarios such as anelastic-anelastic and elastic-anelastic wave propagation in welded and non-welded contact by looking at the transmitted and reflected pulse in welded as well as non-welded contact.

description: TThis is the final report produced in the context of the GEM Strain Rate Project, one of the global components of the GEM Foundation. The project was charged to analyse and synthesize all available geodetic data in order to create a global data set of geodetic velocities that can be used to model plate motions and strain rates in plate boundary zones. To this end, we estimated 6533 velocities from position time-series that we derived from the analysis of RINEX data that was either freely available or made available to us specifically for this project. All but 15 of these velocities were used in the modelling. In a separate analysis, we also re-analysed all RINEX data in China and effectively added 1143 velocities to the data set. Finally, we added 13,318 velocities from 216 studies in the published literature (or from personal communications) to achieve a grand total of 20,979 velocities at 17,491 unique locations used in the modelling. Of all velocities, 16,325 are in plate boundary zones (as defined by us) and the remaining 4654 velocities are for points on, predefined, rigid tectonic plates or blocks. We created a global mesh that has 144,827 deforming cells of 0.2° (latitudinal) by 0.25° (longitudinal) dimension covering the plate boundary zones, with the remaining cells covering 50 rigid plates and blocks. For 36 of these plates, we estimated the rigid-body rotation from our data set, and the rotations of the remaining plates are taken from the literature. The rigid-body rotations are used as boundary conditions in the strain rate calculations. The strain rate field is modelled using the Haines and Holt method, which uses splines to obtain an interpolated velocity gradient tensor field, from which strain rates, vorticity rates, and expected velocities are derived. We also estimated model uncertainties, specific for this high-resolution mesh, which indicates that there still are many areas with large strain rate uncertainties where the data spacing is often much larger than the cell dimensions. Nevertheless, the model and data input are a tremendous improvement to the previous global strain rate model from 2004. All results are transferred to GEM and are also archived and displayed by a dedicated server hosted by UNAVCO (gsrm2.unavco.org), one of the project's partners. In addition, we created a kmz-layer of contour's of the second invariant of the model strain rates, and we created an online tool that would allow a user to upload his own velocities and plot them with the velocities in the GEM dataset in 53 different reference frames.

School-based depression prevention: examination of techniques utilized in groups led by school counselors
Creators: name: Haimm, Caroline
Publisher: name: No Publisher Supplied
Year: 2020

description: As evidence-based programs (EBPs) are transported to more representative clinical settings from highly controlled efficacy trials, their advantage over usual care (UC) is largely diminished. However, it is difficult to explain this phenomenon without a better understanding of the status quo in mental health care. Knowledge of the nature of UC is limited and even less is known about the typical care provided in schools. As a preliminary step towards improving knowledge of school-based services, the current study examined group counseling (GC) sessions led by school counselors for adolescents with elevated depressive symptoms. Group counseling was conducted as part of the Depression Prevention Initiative (DPI), a randomized controlled trial of Interpersonal Psychotherapy – Adolescent Skills Training (IPT-AST), a preventive intervention for adolescent depression. Forty-seven GC sessions were randomly selected for coding using the Therapy Process Observational Coding System for Child Group Psychotherapy (TPOCS-G). Self-report data from the Therapy Procedures Checklist (TPC) was also utilized to describe the range of therapeutic techniques in GC. Additionally, the current study utilized 54 IPT-AST sessions from the DPI project that were coded by a different research group. Independent samples t-tests were used to compare GC and IPT-AST conditions and linear regressions were used to examine whether therapeutic techniques utilized in GC predicted depression and functioning outcomes. School counselors were observed delivering eclectic therapeutic techniques from a variety of theoretical orientations. Shared non-specific factors (e.g., Warmth/Empathy/Validation) were used most frequently, followed by novel unsupported treatment strategies (e.g., Play/Art); evidence-based (EB) techniques were utilized least frequently. Moreover, EB strategies were implemented with low extensiveness, which is inconsistent with EB approaches. Compared to IPT-AST, EB strategies were utilized less frequently and extensively in GC. GC included significantly more non-specific and unsupported strategies than IPT-AST. Within GC, use and extensiveness of EB strategies predicted better depression and functioning outcomes and greater use of non-specific strategies predicted worse functioning outcomes. This work contributes to a growing body of research on UC and may help tailor future training and implementation efforts to meet the unique needs of the education sector.

Photonic Entanglement for a Quantum Repeater

description: Quantum Key Distribution (QKD) has opened a new avenue for secure communication, by allowing one to distribute a random secret key between two users that are connected through a public channel without revealing information to unauthorized parties. If a message is encrypted with the one time pad (a well-known crytography algorithm) using secret keys created by QKD, then the ciphertext is information-theoretically secure and thus unbreakable for adversaries. Despite its unprecedented security, loss in the physical channel has prevented QKD from being used over distances beyond a few hundred kilometers. Fortunately, quantum repeaters have opened a path for long-distance QKD by providing a means to establish entanglement between distant users. The goal of this thesis has been to develop a source of entangled photon pairs that is suitable for quantum repeaters and then use it to test some of the fundamental building blocks of a quantum repeater : the heralded creation of entangled photons by means of entanglement swapping with properties that allow interfacing with optical quantum memories; the reversible mapping of quantum states from members of entangled photon pairs in and out of solid-state quantum memories; two-photon interference and a Bell state measurement with photons recalled from separate quantum memories. The demonstration of these key ingredients of a quantum repeater constitutes a significant step towards the establishment of entanglement over hundreds of kilometer distance, and hence long-distance QKD.
It's just an animal? A theoretical framework for understanding the emergence of animal categories in the United States

description: This dissertation examines why so many Americans have come to accept physically arduous conditions for animal species categorized as "livestock," but have by contrast come to exhibit considerable concern for other animal species that comprise the "endangered species" category. To that end, the research presented here draws largely on Michel Foucault and Clifford Geertz to examine how the animal categories "livestock" and "endangered species" developed in the United States. This research suspends normative claims regarding animal treatment in the United States and employs a Foucaultian perspective to examine how these animal categories emerged in the United States starting in the nineteenth century and how they developed over time. An interpretative framework based on Geertzian analysis supplements the Foucaultian perspective by demonstrating that variations within the two animal categories may also reflect symbolic attachments and systems of self-understanding for Americans. This dissertation yields three conclusions. First, the categories endangered animal species and livestock are not timeless objective technical definitions, but are categories that developed in the last two centuries out of material interests and competing scientific views. These categories function because various techno-scientific elements disconnect humans from animals and produce truths about different animals within a particular system of knowledge, or they operate in a system of meaning as Geertzian analysis reveals. Second, these categories supervene on the singular conception of "animality" that often serves as the conceptual foundation in animal welfare literature, suggesting that it is conceptually not viable to discuss animal welfare issues without reference to a particular category. Since the species in each category serve different functions in a system of managed population and are also situated in systems of meaning and self-understanding, this can explain why the differing standard of treatment that is often considered an ethical contradiction has been firmly maintained in the United States. Third, the following research demonstrates that Foucaultian analysis and Geertzian thick description do not present clear cut, mutually exclusive rival interpretations. Rather, these two approaches can complement one another and in some ways Geertzian analysis confirms the Foucaultian view in this research.

description: Ultra-high temperature (UHT) milk will probably not emerge as a major alternative to regular fluid milk. Although UHT can be stored without refrigeration, its retail price is higher because of the special containers it needs for long shelf life. More important, as a major product, UHT will not significantly reduce the costs of handling supply-demand variability in the milk-marketing system. The relative costs of processing, distributing, and retailing are estimated in this report with economic engineering, linear programming, and simulation techniques.

description: Exoplanets show a pile-up of Jupiter-size planets in orbits with a 3-day period. A fraction of these hot Jupiters have retrograde orbits with respect to the parent star's rotation. To explain these observations we performed a series of numerical integrations of planet scattering followed by the tidal circularization. We considered planetary systems having 3 and 4 planets initially. We found that the standard Kozai migration is an inefficient mechanism for the formation of hot Jupiters. Our results show the formation of two distinct populations of hot Jupiters. The inner population of hot Jupiters with semimajor axis a < 0.03 AU formed in the systems where no planetary ejections occurred. This group contained a significant fraction of highly inclined and retrograde orbits, with distributions largely independent of the initial setup. However, our follow-up integrations showed that this populations was transient with most planets falling inside the Roche radius of the star in <1 Gyr. The outer population of hot Jupiters formed in systems where at least one planet was ejected. This population survived the effects of tides over >1 Gyr. The semimajor axis distribution of Population II fits nicely the observed 3-day pile-up. The inclination distribution of the outer hot planets depends on the number of planets in the initial systems and the 4-planet case showed a larger proportion (up to 10%), and a wider spread in inclination values. As the later results roughly agrees with observations, this may suggest that the planetary systems with observed hot Jupiters were originally rich in the number of planets, some of which were ejected. In a broad perspective, our work therefore hints on an unexpected link between the hot Jupiters and recently discovered free floating planets.

description: We investigate the structure of admixed neutron stars with a regular hadronic component and a fraction of fermionic self-interacting dark matter. Using two limiting equations of state for the dense baryonic interior, constructed from piecewise generalised polytropes, and an asymmetric self-interacting fermionic dark component, we analyse different scenarios of admixed neutron stars depending on the mass of dark fermions $m_χ$, interaction mediators $m_ϕ$, and self-interacting strengths $g$. We find that the contribution of dark matter to the masses and radii of neutron stars leads to tension with mass estimates of the pulsar J0453+1559, the least massive neutron star, and with the constraints coming from the GW170817 event. We discuss the possibilities of constraining dark matter model parameters $g$ and $y \equiv m_χ/m_ϕ$, using current existing knowledge on neutron star estimations of mass, radius, and tidal deformability, along with the accepted cosmological dark matter freeze-out values and self-interaction cross-section to mass ratio, $σ_\mathrm{SI}/m_χ$, fitted to explain Bullet, Abell, and dwarf galaxy cluster dynamics. By assuming the most restrictive upper limit, $σ_\mathrm{SI}/m_χ< 0.1$ cm$^2$/g, along with dark matter freeze-out range values, the allowed $g$-$y$ region is $0.01 \lesssim g \lesssim 0.1$, with $0.5 \lesssim y \lesssim 200$. For the first time, the combination of updated complementary restrictions is used to set constraints on self-interacting dark matter.

description: Contract farming is becoming increasingly important in developing countries, to coordinate transactions along agricultural supply chains. In this paper, we examine the diet and nutrition implication of engaging in contract farming among smallholder farmers in Ghana. Previous studies have analyzed the effects of contract farming on farm production and household income. However, little is known about the effects of contract farming on household and individual nutrition. We know of no study that has analyzed the effects of contract farming on household and individual dietary diversity, as well as on anthropometric measures. Our study further contributes to the existing literature by investigating differences in effects across different types of contracts, which has largely been neglected. Results show that producing oil palm under contract has implications for household and individual nutrition. However, the effect depends on the type of contract. Resource-providing contracts lead to higher dietary diversity at the household level, as well as for female household members. Our findings also reveal that children in households with resource providing contracts have a higher height-for-age z-score (HAZ) and weight-for-age z-score (WAZ), suggesting positive long-term nutritional benefits for small children aged 2-6 years. The effects of marketing contracts are less clear. The results indicate positive effects on women’s dietary diversity and on the child’s weight-for-age z-score. Additionally, we find positive nutrition effects if the contracted farmer is female.
