description: Temporal variations in gas hydrate related geochemical signatures under different deposition conditions are the primary purposes of this study. Accreted wedge located offshore Southwestern Taiwan receives high terrigenous river materials, 100 MT/yr, at present time. It is not clear how seep environment varied during the past glacial. A 25 meters long piston core was taken offshore Southwestern Taiwan on r/v Marion DuFresne. Short piston cores and box cores were also taken on r/v OR-1. Samples were analyzed for pore water dissolved sulfide, sulfate, methane, chloride, del O18, calcium, magnesium, alkalinity, pH, and sediment AVS, pyrite, inorganic carbon, del O- 18, C13. Changes in deposition environment play a major role in the study area. Three stages of geochemical processes are identified in the 25 meters long core, interchange between reduce and oxic depositional environments, with reducing condition in the top 10 m, oxic in between 10-20 meter and reducing below the 20 meter. High concentrations of dissolved sulfide, rapid sulfate depletion, increase of methane, decrease of calcium were found in pore water in the top 10 m of sediments together with high concentrations of pyrite, relatively higher proportion of coarsegrained sediment. Concentrations of pyrite were very low in sediments between 15 to 20 meters but increased rapidly from 20 to 25 meters with a maximum concentration at 400 umol/g. Chloride concentrations also increased to a maximum concentration of 630 mM at 20 m. The rapid increase of chloride indicated gas hydrate formation at this depth. Authigenic carbonate nodules were found in sediments below 20 m. The carbonate content also increased rapidly beneath this depth. Stable isotopic carbon composition of the carbonate varied rapidly beneath 20 m with a low at -28 per mil. The existence of oxic/reducing alterations indicates that methane seep may vary in the past in the study area.
A Geometry for Multidimensional Integrable Systems

description: A deformed differential calculus is developed based on an associative star-product. In two dimensions the Hamiltonian vector fields model the algebra of pseudo-differential operator, as used in the theory of integrable systems. Thus one obtains a geometric description of the operators. A dual theory is also possible, based on a deformation of differential forms. This calculus is applied to a number of multidimensional integrable systems, such as the KP hierarchy, thus obtaining a geometrical description of these systems. The limit in which the deformation disappears corresponds to taking the dispersionless limit in these hierarchies.

description: Real estate is one of the largest and most complex markets globally. Dynamic consumer behaviour, such as that which results in the rapid rate of urbanisation, has caused these complexities, and thus, understanding and predicting these market behavioural patterns has become a challenge. As a result, many countries have failed to develop adequate policies to mitigate the risk of market uncertainties and abnormal behaviours that result in issues such as the affordable housing crisis. However, many global institutions still struggle to understand the real estate market using only the currently available tools; thus, many researchers are now testing more innovative cutting-edge technologies to help manage this complex market. Therefore, this research explores how machine learning (ML) and artificial intelligence (AI) can produce relatively valuable and accurate insights into the problems of the market compared to the traditional methods of understanding the complex housing market in Australia. Just as many other industries are now deploying AI and ML in decision-making processes, the real estate industry is also embracing ML to improve the efficiency and effectiveness of many processes. Further, the inability of traditional analytical methodologies to deliver better insights into the ever-growing complexity of the housing markets has encouraged AI and ML to do the job. The development of big data technologies and the availability of massive data pools have enabled AI and ML to solve complicated problems while producing more accurate results. Thus, this research productively addresses the complexity of the Australian housing market using AI and ML and helps decision-makers manage associated issues. The research consists of three studies: the first focuses on overall Australia, and the other two focus on Queensland, Australia. [...]

description: We investigate the optimal aesthetic location and size of a single dominant salient region in a photographic image. Existing algorithms for photographic composition do not take full account of the spatial positioning or sizes of these salient regions. We present a set of experiments to assess aesthetic preferences, inspired by theories of centeredness, principal lines, and Rule-of-Thirds. Our experimental results show a clear preference for the salient region to be centered in the image and that there is a preferred size of non-salient border around this salient region. We thus propose a novel image cropping mechanism for images containing a single salient region to achieve the best aesthetic balance. Our results show that the Rule-of-Thirds guideline is not generally valid but also allow us to hypothesize in which situations it is useful and in which it is inappropriate.

description: The Rule of Thirds is a well known heuristic in photo composition. The professional photography community both uses it and derides it. We report on an experiment to test the validity of the Rule of Thirds in the simplest case: composition of a single object. Our results show that our participants overwhelmingly preferred a centered object in the image to one positioned according to the Rule of Thirds. We speculate why this is so and point to other research that addresses how we can take advantage of this “salient centeredness”.

description: In supervised learning, the redundancy contained in random examples can be avoided by learning from queries. Using statistical mechanics, we study learning from minimum entropy queries in a large tree-committee machine. The generalization error decreases exponentially with the number of training examples, providing a significant improvement over the algebraic decay for random examples. The connection between entropy and generalization error in multi-layer networks is discussed, and a computationally cheap algorithm for constructing queries is suggested and analysed.

description: Sustainable development is often taken to mean development that improves human well being subject to natural constraints over time, but in practice quantifying sustainability outcomes is often difficult. In this dissertation I seek to better elucidate the relationship between sustainable development and its natural constraints by focusing on human capital outcomes, which I argue provide one of our best summary statistics for "human well being" in general. Whether the constraints are imposed by natural systems (Chapters 2 and 3) or human ones (Chapter 4) I find strong evidence to suggest that attempts to pursue sustainable economic development must deal with nuanced and often conflicting interactions between the human capital invesment and accumulation process and its fundamental constraints.

Assuming the Friedmann-Lemaître-Robertson-Walker type of the metric for both sheets we obtain the action, which in addition to the the usual cosmological constant terms and the Einstein-Hilbert term involves a nonlinear interaction term. We study qualitative picture of potential consequences of such term in the basic cosmological models.

Pyykko, Mol. Phys. 116, 1328 (2018)] and earlier results [e.g. A. M. Matensson-Pendrill, J. Phys. B: At. Mol. Opt. Phys. 35, 917 (2002); K. Z. Yu et al., Phys. Rev. A 70, 012506 (2004)]. In this work, we reported a new value, Q(87Sr) = 328(4) mb, making use of our calculated electric field gradients produced by electrons at nucleus in combination with experimental values for hyperfine structures of the 5s5p 3P1,2 states of the neutral Sr atom. In the framework of the multi-configuration Dirac-Hartree-Fock theory, the electron correlations were taken into account systematically so as to control the uncertainties of the electric field gradient at about 1% level. The present result is different from the recommended value, but in excellent agreement with those by Matensson-Pendrill and Yu et al.. We would recommend the present Q value as a reference for 87Sr.

description: Abstract: The paper titled, ‘Inappropriate Observations by Judges during Judicial Proceedings: Issues and Perspectives’ examines various institutional and legal issues arising out of the recent instances of some judges from various High Courts making inappropriate and even intemperate observations against one or other litigants. The Supreme Court of India also had opportunity to examine these issues in a recently delivered judgment in case of Chief Election Commissioner of India (Appellant) Versus M.R Vijayabhaskar & Ors. (Respondents) in Civil Appeal No. 1767 of 2021 (Arising out of SLP (C) No. 6731 of 2021). Various institutional and legal issues arising out of such inappropriate observations by the judges in the course of judicial proceedings, particularly when they are oral, are numerous and complex. The present paper examines them issue-wise and builds up a framework for better jurisprudential understanding and better institutional responses to these instances of inappropriate observations emanating from judges in the course of judicial proceedings.

Exact solution of multi-angle quantum many-body collective neutrino flavor oscillations

description: I study the flavor evolution of a dense neutrino gas by considering vacuum contributions, matter effects and neutrino self-interactions. Assuming a system of two flavors in a uniform matter background, the time evolution of the many-body system in discretized momentum space is computed. The multi-angle neutrino-neutrino interactions are treated exactly and compared to both the single-angle approximation and mean field calculations. %The time unit chosen is $μ_0^{-1}=(\frac{G_F}{2\sqrt{2}V})^{-1}$. The mono-energetic two neutrino beam scenario is solved analytically. I proceed to solve flavor oscillations for mono-energetic cubic lattices and quadratic lattices of two energy levels. In addition I study various configurations of twelve, sixteen, and twenty neutrinos. I find that when all neutrinos are initially of the same flavor, all methods agree. When both flavors are present, I find collective oscillations and flavor equilibration develop in the many body treatment but not in the mean field method. This difference persists in dense matter with tiny mixing angle and it can be ascribed to non-negligible flavor polarization correlations being present. Entanglement entropy is significant in all such cases. The relevance for supernovae or neutron stars mergers is contingent upon the value of the normalization volume $V$ and the large $N$ dependence of the timescale associated with oscillations. In future work, I intend to study this dependence using larger lattices and also include anti-neutrinos.

description: Transportation problems such as traffic congestion and traffic emission draw growing attention along with rapid urbanization and growth of urban transportation sector in developing countries. This dissertation focuses on a series of transportation policies implemented by the government of Beijing and explores their potential effects in the aspect of reducing traffic congestion, improving air quality, and saving energy. This dissertation is composed by three essays. The first essay exploits an idiosyncratic feature of a driving restriction policy and examines the effects of having more vehicles on the road on traffic congestion, ambient air pollution, and contemporaneous health. The findings suggest that traffic congestion has substantial environmental and health externalities in Beijing but that they are also responsive to policy. The second essay explores the effects of opening new subway lines on traffic congestion and ambient air pollution in Beijing. Results show that the expansion of subway networks significantly decreases traffic congestion, and is associated with improvements in air quality in areas located close to the newly opened subway lines. The third essay estimates the price and income elasticities of vehicular gasoline demand to explore the potential effect of fuel tax on transportation gasoline consumption in Beijing.

description: This paper is the first in a series of papers developing a functional-analytic theory of vertex (operator) algebras and their representations. For an arbitrary Z-graded finitely-generated vertex algebra (V, Y, 1) satisfying the standard grading-restriction axioms, a locally convex topological completion H of V is constructed. By the geometric interpretation of vertex (operator) algebras, there is a canonical linear map from the tensor product of V and V to the algebraic completion of V realizing linearly the conformal equivalence class of a genus-zero Riemann surface with analytically parametrized boundary obtained by deleting two ordered disjoint disks from the unit disk and by giving the obvious parametrizations to the boundary components. We extend such a linear map to a linear map from the completed tensor product of H and H to H, and prove the continuity of the extension. For any finitely-generated C-graded V-module (W, Y_W) satisfying the standard grading-restriction axioms, the same method also gives a topological completion H^W of W and gives the continuous extensions from the completed tensor product of H and H^W to H^W of the linear maps from the tensor product of V and W to the algenbraic completion of W realizing linearly the above conformal equivalence classes of the genus-zero Riemann surfaces with analytically parametrized boundaries.

A cell-wide investigation of the RNA-binding proteins modulated by starvation and stimulation with insulin
Creators: name: Dezi, Veronica
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: The development of cutting-edge proteomic techniques has recently enabled to comprehensively catalogue more than a thousand of RBPs (RNA-binding proteins) across different cell types, tissues and whole organisms. Interestingly, these methods can be employed to interrogate the effect of either cell stress or stimulation on protein-RNA interactions and can be used to uncover novel RBP candidates or new functions of well-known RBPs.This study aimed at investigating RBPs dynamics in untransformed epithelial MCF10A cells subjected to growth factor deprivation and stimulation with insulin. Both treatments have been shown to modulate RNA metabolism and primarily mRNA translation through regulation of the mTOR signalling pathway.By performing OOPS (Orthogonal organic phase separation), it was possible to identify a large number of RBPs, the interaction of which was significantly affected by starvation and stimulation with insulin, including the tumour suppressor PDCD4 (Programmed cell death protein 4).Downregulation of PDCD4 has been observed to enhance tumour progression and invasion of many different cancers. The protein is primarily a translation repressor; it impedes the physical interaction between eIF4A and eIF4G and it compromises the expression of mRNAs with highly structured 5’UTR. However, PDCD4 was also found to directly bind specific region within the coding sequence of few mRNAs and slow down their translation elongation.Although the protein harbours an N-terminal disordered region with RNA-binding potential, its relevance and its direct RNA targets have not been fully investigated in a genome-wide study. With this in mind, the PDCD4-bound transcriptome was investigated by iCLIP (Individual-nucleotide resolution UV crosslinking and immunoprecipitation) in untransformed cells and it revealed more than 150 RNA partners, the regulation of which might play a significant role during cancer development.

description: $α$ elastic and inelastic scattering on $^{12}$C is investigated with the coupled-channel calculation using microscopic $α$-$^{12}$C potentials, which are derived by folding the Melbourne $g$-matrix $NN$ interaction with the matter and transition densities of $^{12}$C. These densities are obtained by a microscopic structure model of the antisymmetrized molecular dynamics combined with and without the $3α$ generator coordinate method. The calculation reproduces satisfactorily well the observed elastic and inelastic cross sections at incident energies of $E_α=130$~MeV, 172.5~MeV, 240~MeV, and 386~MeV with no adjustable parameter. Isoscalar monopole and dipole excitations to the $0^+_2$, $0^+_3$, and $1^-_1$ states in the $α$ scattering are discussed.

description: Few sectors of the economy are as influential to the environment and are as susceptible to the influence of environmental changes as agriculture. This dissertation contains three chapters that examine agriculture as the primary interface at which human and nature interact. Primarily, I explore how policy support for financial risk management tools can have substantial impact on agricultural production choices via moral hazard and selection problems. While mitigating agricultural production risk, these supports also impact the environment via induced change in production choices. This dissertation contributes to U.S. agriculture policy and pollution management literature and insurance literature on moral hazard and selection problems. By examining the case of Federal Crop Insurance Program in the United States, this dissertation explores input choice changes caused by changes in government support for crop insurance. I proposed theoretical mechanism through which increasing use of financial risk management strategy can influence input decisions with risk implications, and tested these theories empirically with county-level panel data. Empirical tests showed that there were substantial decreases in irrigation investment and fertilizer application due to crop insurance offering. Policy implications on water scarcity and non-point source pollution management and on federal support to crop insurance market are discussed.
Chromatic Polynomials for Families of Strip Graphs and their Asymptotic Limits

description: We calculate the chromatic polynomials $P((G_s)_m,q)$ and, from these, the asymptotic limiting functions $W(\{G_s\},q)=\lim_{n \to \infty}P(G_s,q)^{1/n}$ for families of $n$-vertex graphs $(G_s)_m$ comprised of $m$ repeated subgraphs $H$ adjoined to an initial graph $I$. These calculations of $W(\{G_s\},q)$ for infinitely long strips of varying widths yield important insights into properties of $W(Λ,q)$ for two-dimensional lattices $Λ$. In turn, these results connect with statistical mechanics, since $W(Λ,q)$ is the ground state degeneracy of the $q$-state Potts model on the lattice $Λ$. For our calculations, we develop and use a generating function method, which enables us to determine both the chromatic polynomials of finite strip graphs and the resultant $W(\{G_s\},q)$ function in the limit $n \to \infty$. From this, we obtain the exact continuous locus of points ${\cal B}$ where $W(\{G_s\},q)$ is nonanalytic in the complex $q$ plane. This locus is shown to consist of arcs which do not separate the $q$ plane into disconnected regions. Zeros of chromatic polynomials are computed for finite strips and compared with the exact locus of singularities ${\cal B}$. We find that as the width of the infinitely long strips is increased, the arcs comprising ${\cal B}$ elongate and move toward each other, which enables one to understand the origin of closed regions that result for the (infinite) 2D lattice.

description: The driver’s instantaneous situation awareness in the process of take-over of vehicle control in automated driving has not yet been thoroughly investigated. The proposed research can provide a better understanding of the driver’s perceived characteristics and identify the most urgent information requirements of the on-site scenario when the driver’s eye sight returns from other distractors to the driving scene. We conducted an experiment in simulated automated driving to study the participants’ ability of instantaneous hazard perception and judgment. The scene pictures, which were displayed in millisecond time, were used to imitate the situations that drivers would see when the distracted drivers returned their gaze from the distractive sources to the road in the simulated automated driving. The results show that the driving state, scene representation time and hazard levels affect the instantaneous situation awareness of drivers. In addition, the scene perception accuracy of the group who played games during automated driving is much lower than that of the group that chatted with the copilot. The longer picture-showing duration decreases the accuracy of hazard identification, whereas the shorter picture-showing duration increases the accuracy of hazard perception and the hazard rating score. In conclusion, distraction reduces the accuracy of the instantaneous scene perception of drivers, and drivers behave more cautiously in decision making when the driving situations are more hazardous. This study provides a good theoretical basis for the design of hazard warning information for automated driving.

description: This dissertation provides three examples of how considering interactions across transport modes as well as land use systems is important for addressing the biggest challenges in sustainable development, particularly climate change and growing inequality. In the first essay, I explore path dependency in urban form for U.S. cities built around rail transit prior to the automobile. I find that these cities continue to be denser and have lower per capita transportation emissions than cities that came of age after the automobile. I estimate the size of the effect and how long it lasts. The built environment is durable, and urban infrastructure is costly to alter post-construction, so land use and transport decisions made early in a city’s history can have a lasting environmental impact. The second essay exploits a natural experiment to quantify the impact of bikesharing on bus transit ridership in New York City. This work demonstrates one way in which shared modes impact pre-existing public transit systems, which is particularly important as these systems are expanding and operating outside of traditional public agencies. The way these modes work together determines the overall quality of the transport network. The third essay discusses the concept of accessibility and how accessibility measures can be used in the case of Nairobi to explore the dynamics of social exclusion across modes, residential location, and income. This dissertation provides three examples of how sustainability goals may fall short if transportation is not viewed as a multimodal system that interacts with and shapes urban form.

chromatin accessibility

description: Here we provided the weights for a trained DeepAccess model, an ensemble of neural networks predicting accessibility from DNA sequence. We trained this model on ATAC-seq data from ten mouse cell types: stem cell, fibroblast, hepatocyte, endoderm, beta pancreatic cell, alpha pancreatic cell, cardiomyocyte, skeletal muscle, dopaminergic midbrain neuron, and spinal motor neuron using binary cross-entropy loss (multi-task classification) with 4,220,507 genomic regions for training: 3,220,507 regions were open in at least 1 cell type, and 1,000,000 regions were closed in all cell types (randomly sampled from the genome). Chromosome 18 and chromosome 19 were held out for validation and testing, respectively. To define training regions for DeepAccess, we generate 100bp genomic windows across the entire mouse genome. We define a region as accessible in a given cell type if more that 50% of the 100bp region overlaps a MACS2(43) accessible region from that cell type.

Toroidal and level 0 U'_q(\hat{sl_{n+1}}) actions on U_q(\hat{gl_{n+1}}) modules
Creators: name: Miki, Kei
Publisher: name: arXiv

Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: (1) Utilizing a Braid group action on a completion of U_q(\hat{sl_{n+1}}), an algebra homomorphism from the toroidal algebra U_q(sl_{n+1,tor}) (n\ge 2) with fixed parameter to a completion of U_q(\hat{gl_{n+1}}) is obtained. (2) The toroidal actions by Saito induces a level 0 U'_q(\hat{sl_{n+1}}) action on level 1 integrable highest weight modules of U_q(\hat{sl_{n+1}}). Another level 0 U'_q(\hat{sl_{n+1}}) action is defined by Jimbo, et al., in the case n=1. Using the fact that the intertwiners of U_q(\hat{sl_{n+1}}) modules are intertwiners of toroidal modules for an appropriate comultiplication, the relation between these two level 0 U'_q(\hat{sl_{n+1}}) actions is clarified.

description: We derive analytical solutions for p-spin models with finite connectivity at zero temperature. These models are the statistical mechanics equivalent of p-XORSAT problems in theoretical computer science. We give a full characterization of the phase diagram: location of the phase transitions (static and dynamic), together with a description of the clustering phenomenon taking place in configurational space. We use two alternative methods: the cavity approach and a rigorous derivation.

description: We present a unified variational treatment of the magnetic dipole matrix elements, Einstein coefficients and line strength for general open-shell diatomic molecules in the general purpose diatomic code Duo. Building on previous work in which similar expressions for the electric quadrupole transitions were developed, we also present a complete ab initio spectroscopic model for the infrared, electric dipole-forbidden, spectrum of the $^{16}$O$_2$ molecule. The model covers seven states, namely the X $^3Σ^-_g$, a $^1Δ_g$, b $^1Σ^+_g$, I $^1Π_g$, II $^1Π_g$, I $^3Π_g$ and II $^3Π_g$ states, for which 7 potential energy, 6 electronic angular momentum, 7 spin-orbit, and 14 quadrupole moment curves are calculated using ic-MRCI theory and an aug-cc-pV5Z basis set. These curves are diabatised to remove avoided crossings between the excited $Π$ states, and the resultant properties are used to produce a line list for higher-order transitions of astrophysical interest.

description: We develop a lower critical field (Hc1) measurement system using the third-harmonic response of an applied AC magnetic field from a solenoid coil positioned above a superconducting sample. Parameter Hc1 is measured via detection of the third-harmonic component, which drastically changes when a vortex begins to penetrate the superconductor with temperature increase. The magnetic field locally applied to one side of the sample mimics the magnetic field within superconducting radio-frequency (SRF) cavities and prevents edge effects of the superconducting sample. With this approach, our measurement system can potentially characterize surface-engineered SRF materials such as Superconductor-Insulator-Superconductor multilayer structure (S-I-S structure). As a validation test, we measure the temperature dependence of Hc1 of two high-RRR bulk Nb samples and obtain results consistent with the literature. We also confirm that our system can apply magnetic fields of at least 120 mT at 4-5 K without any problem of heat generation of the coil. This field value is higher than those reported in previous works and makes it possible to more accurately estimate Hc1 at lower temperatures.

description: Objective: The objective was to identify clinically meaningful groups of adolescents based on self-reported mental health and wellbeing data in a population sample of New Zealand secondary school students. Methods: We conducted a cluster analysis of six variables from the Youth19 Rangatahi Smart Survey ( n = 7721, ages 13–18 years, 2019): wellbeing (World Health Organization Well-Being Index), possible anxiety symptoms (Generalized Anxiety Disorder 2-item, adapted), depression symptoms (short form of the Reynolds Adolescent Depression Scale) and past-year self-harm, suicide ideation and suicide attempt. Demographic, contextual and behavioural predictors of cluster membership were determined through multiple discriminant function analysis. We performed cross-validation analyses using holdout samples. Results: We identified five clusters ( n = 7083). The healthy cluster ( n = 2855, 40.31%) reported positive mental health across indicators; the anxious cluster ( n = 1994, 28.15%) reported high possible anxiety symptoms and otherwise generally positive results; the stressed and hurting cluster ( n = 667, 9.42%) reported sub-clinical depression and possible anxiety symptoms and some self-harm; the distressed and ideating cluster ( n = 1116, 15.76%) reported above-cutoff depression and possible anxiety symptoms and high suicide ideation; and the severe cluster ( n = 451; 6.37%) reported the least positive mental health across indicators. Female, rainbow, Māori and Pacific students and those in higher deprivation areas were overrepresented in higher severity clusters. Factors including exposure to sexual harm and discrimination were associated with increasing cluster severity. Conclusion: We identified high prevalence of mental health challenges among adolescents, with distinct clusters of need. Youth mental health is not ‘one size fits all’. Future research should explore youth behaviour and preferences in accessing support and consider how to best support the mental health of each cluster.

description: We consider infinite dimensional optimization problems motivated by the financial model called Arbitrage Pricing Theory. Using probabilistic and functional analytic tools, we provide a dual characterization of the super-replication cost. Then, we show the existence of optimal strategies for investors maximizing their expected utility and the convergence of their reservation prices to the super-replication cost as their risk-aversion tends to infinity.
