description: Our nervous system is made of billions of neurons that process sensory information and control behavior. It is organized into circuits with specifically tuned cell-to-cell connections that are essential for proper function. During development, neurons project to remote locations in search of their synaptic partners. Surrounded by numerous cells along their trajectory and in their target area, these developing neurons ignore most neurons with which they come into contact and connect with very specific partners. The mechanisms by which presynaptic axon terminals and postsynaptic dendrites recognize each other and establish the correct number of connections with the appropriate strength are poorly understood. Sperry’s chemoaffinity hypothesis proposes that pre- and postsynaptic partners express specific combinations of molecules that enable them to recognize each other. Alternatively, Peters’ rule proposes that presynaptic axons and postsynaptic dendrites use non-partner-derived global positional cues to independently reach their target area, and once there they randomly connect with any available neuron. These connections can then be further refined by additional mechanisms based on synaptic activity. I use the Drosophila embryo and larva, a tractable model system, to test these hypotheses and elucidate the roles of 1) global positional cues, 2) partner-derived cues and 3) synaptic activity in the establishment of selective connections in the developing nerve cord. I altered the position or activity of presynaptic partners and analyzed the effect of these manipulations on number of synapses with postsynaptic partners, strength of functional connections, and behavior controlled by these neurons. For this purpose, I combined developmental live imaging, electron microscopy reconstruction of circuits, functional imaging of neuronal activity, and behavioral experiments in wildtype and experimental animals. I found that postsynaptic dendrites are able to find, recognize, and connect to their presynaptic partners even when these have been shifted to ectopic locations through the overexpression of receptors for midline guidance cues. This suggests that neurons use partner-derived cues that allow them to identify and connect to each other. However, while partner-derived cues are sufficient for recognition between specific partners and establishment of connections; without orderly positioning of axon terminals by positional cues and without synaptic activity during embryonic development, the number and strength of functional connections are altered with significant consequences for behavior. Thus, multiple mechanisms including global positional cues, partner-derived cues, and synaptic activity contribute to proper circuit assembly in the developing Drosophila nerve cord.

description: A Helson matrix is an infinite matrix $A = (a_{m,n})_{m,n\geq1}$ such that the entry $a_{m,n}$ depends only on the product $mn$. We demonstrate that the orthogonal projection from the Hilbert--Schmidt class $\mathcal{S}_2$ onto the subspace of Hilbert--Schmidt Helson matrices does not extend to a bounded operator on the Schatten class $\mathcal{S}_q$ for $1 \leq q \neq 2 < \infty$. In fact, we prove a more general result showing that a large class of natural projections onto Helson matrices are unbounded in the $\mathcal{S}_q$-norm for $1 \leq q \neq 2 < \infty$. Two additional results are also presented.

description: Acoustic imaging sonars have been used for a variety of tasks intended to increase the autonomous capabilities of underwater vehicles. Among the most critical tasks of any autonomous vehicle are localization and mapping, which are the focus of this work. The difficulties presented by the imaging sonar sensor have led many previous attempts at localization and mapping with the imaging sonar to make
restrictive assumptions, such as a planar seafloor environment or planar sensor motion. Lifting such restrictions is an important step toward achieving general-purpose autonomous localization and mapping in real-world environments. In this dissertation, I take inspiration from related problems in the field of computer vision and demonstrate that imaging sonar localization and mapping may be modeled and solved using similar methods. To achieve accurate large-scale localization, I present degeneracy-aware acoustic bundle adjustment, a feature-based algorithm inspired by optical bundle adjustment. To achieve 3-D mapping of underwater surfaces, I propose several distinct algorithms. First, I present a method akin to
shape-from-shading that uses a generative sensor model to infer a dense pointcloud from each image and fuses multiple such observations into a global model. Second, I describe a volumetric albedo framework for general-purpose sonar reconstruction, which derives from the related problem of non-line-of-sight reconstruction. This method performs inference over the elevation aperture and generates best results with a rich variety of viewpoints. Lastly, I present the theory of Fermat paths for sonar reconstruction, which utilizes the 2-D Fermat flow equation to reconstruct a
particular set of object surface points with short baseline motion.

description: We investigate the flux and the event rate of the supernova relic neutrino background (SRN) at the SuperKamiokande detector for various neutrino oscillation models with parameters inferred from recent experimental results. A realistic model of neutrino emission from supernova explosions and several models of the cosmic star formation history are adopted in the calculation. The number flux over entire energy range is found to be $11-15 \mathrm{cm^{-2}s^{-1}}$. We discuss the detection possibility of SRN at SuperKamiokande, comparing this SRN flux with other background neutrinos in more detail than previous studies. Even though there is no energy window in which SRN is dominant, we might detect it as the distortion of the other background event. We found in the energy range $17-25 \mathrm{MeV}$ the expected event rate at SuperKamiokande $0.4-0.8 ~\mathrm{yr^{-1}}$. In this range, ten-year observation might enable us to detect SRN signal (at one sigma level) in the case of LMA solar neutrino solution. We also investigate event rate at SNO and KamLAND. Although we can find energy window, the expected event rate is rather small (0.03 yr$^{-1}$ for SNO, 0.1 yr$^{-1}$ for KamLAND).

description: This study compares productivity and equity performance of deep tubewells (DTWs) under different management systems (rental, KSS and private). Results show that the command area per MW, and output and gross return per unit of land were significantly higher under private management than under KSS and rental management. However, farmers' gross margin, return over cash cost and full cost of HYV Boro paddy produced under rented DTW schemes appeared to be higher than those under KSSDTWs and private DTWs. As regards the equity issue, it was observed that the produced benefits from irrigation were relatively more equally distributed to the farmers under KSS-D'I'Ws• compared to private D'IWs and rented DTWs. It revealed that private DTWs showed somewhat better performance from the view point of DTW managers/owners, while rented DTWs showed somewhat better performance from the view point of farmers. It is also concluded that KSS managed DTWs showed a little better performance with respect to farmers access to produced benefits from irrigation schemes.

description: The transportation system is a complex interaction between the infrastructure, vehicles, and users. Over time, many innovations have come through in the field of transportation. The connected vehicle technology is one such innovation with potential to improve mobility, reduce congestion, and enhance safety of the transportation system. However, the successful deployment of connected vehicle technology depends on improved system-level performance and user experiences. In order to understand and assess the real-world behavior of this technology, the United States Department of Transportation (USDOT) has built several testbeds across the United States. The focus of this research is to evaluate the effectiveness of a connected vehicle environment using the trajectory data of test vehicles collected from the Arizona testbed, United States, an arterial corridor with a series of signalized intersections. Vehicle to infrastructure communication using the dedicated short range communication (DSRC) technology was tested along this corridor. The test vehicle trajectories were captured after processing data points obtained from a Global Positioning System (GPS) device. The trends in built trajectories in the connected vehicle environment and base condition were compared by time of the day. The results show a statistically significant increase in the average speed of the test vehicles along the arterial corridor in the connected environment compared to the base condition.

description: Capsule Networks (CapsNets) are brand-new architectures that have shown ground-breaking results in certain areas of Computer Vision (CV). In 2017, Hinton and his team introduced CapsNets with routing-by-agreement in "Sabour et al" and in a more recent paper "Matrix Capsules with EM Routing" they proposed a more complete architecture with Expectation-Maximization (EM) algorithm. Unlike the traditional convolutional neural networks (CNNs), this architecture is able to preserve the pose of the objects in the picture. Due to this characteristic, it has been able to beat the previous state-of-theart results on the smallNORB dataset, which includes samples with various view points. Also, this architecture is more robust to white box adversarial attacks. However, CapsNets have two major drawbacks. They can't perform as well as CNNs on complex datasets and, they need a huge amount of time for training. We try to mitigate these shortcomings by finding optimum settings of EM routing iterations for training CapsNets. Unlike the past studies, we use un-equal numbers of EM routing iterations for different stages of the CapsNet. For our research, we use three datasets: Yale face dataset, Belgium Traffic Sign dataset, and Fashion-MNIST dataset.

description: Genetic and genomic approaches have revolutionised the way we address disease aetiology, potential treatment and methods to understand fundamental biology. Many different approaches can be applied to attempt to resolve the mechanisms through which sequence variation disrupts downstream biological processes, which I discuss and apply in this thesis. Specifically, I use tractable haematopoietic cellular systems focusing mainly on neutrophils but also extending these analyses to monocytes and naïve CD4+ cells. First, I introduce the fundamental principles of human genetic variation and associated challenges in resolving functional mechanisms. I then discuss how immune functions are dysregulated in classical autoimmune diseases and emerging evidence for the role of these cells in complex disorders not previously considered immune-mediated. I then integrate molecular phenotypes from resting monocytes, neutrophils and CD4+ T cells with disease-risk loci. Molecular data have the advantage of enabling measurement in larger cohorts and have therefore been used in quantitative trait loci studies to identify variants influencing processes such as gene expression, histone modification or splicing. Using these data, I map molecular mechanisms acting at risk loci associated with a range of complex disorders. Following this, I highlight recent efforts in applying systematic genome-wide association approaches to cellular and functional traits, many of which can represent intermediate processes disrupted by complex disease. I then apply such approaches to novel neutrophil functional phenotypes to ascertain whether such population-based approaches can be used to gain insight into neutrophil biology. Finally, I discuss studies of haematological blood cell count traits and immunophenotyping and apply a targeted recall-by-genotype study to dissect the relationship between these traits, specifically neutrophil count and surface receptor expression. In summary, I demonstrate how describing biological mechanisms of genetic variants requires the integration of multiple and complementary datasets and offers insight into fundamental biology, disease risk and therapeutic utility.

description: Objectives: To introduce a psychological model of behaviour; the COM-B model and describe how this has been used in combination with the behaviour change wheel (BCW) in developing an intervention which aims to promote regular, long-term use of hearing aids by adults with acquired hearing loss. Design: Qualitative structured interview study using the COM-B model to identify the determinants of behavioural planning on the part of audiologists; a potentially important factor in encouraging long-term hearing-aid use. Study sample: Ten audiologists drawn from a random sample of five English audiology departments. Results: The analysis suggests that behavioural planning might be more likely to occur if audiologists’ psychological capability, physical and social opportunity, and reflective and automatic motivation were addressed. This analysis forms the basis of an intervention design, using the BCW, to encourage behavioural planning by audiologists and subsequent hearing-aid use by people with hearing loss. Conclusions: The COM-B model and BCW can be applied successfully in the context of audiology to analyse the behaviour of both people with hearing loss and professionals working with them, supplying information that is being used in intervention design. The effectiveness of the intervention will be tested in a clinical trial.

description: Spintronic technology utilises the spin of electrons as an extra degree of freedom to store and process information in microelectronic devices. Of special interest among all spintronic materials are topological insulators (TIs), which have insulating bulk but conductive surface states. In this thesis, a comprehensive study of various TI and non-TI spintronic systems is presented, with an emphasis on the magneto-optic Kerr effect (MOKE) characterisation. The design and construction of a MOKE microscope is described, for simultaneous magneto-optical and magneto-transport measurements in an applied field of up to 9 T at temperatures from 1.5 to 300 K. This microscope is used to study Cr:Sb$_2$Te$_3$, (Cr,V):Sb$_2$Te$_3$, EuS/Bi$_2$Se$_3$, and [Cr:Sb$_2$Te$_3$/Dy:Bi$_2$Te$_3$]$_{10}$ magnetic TI thin films. A good agreement is established between the electrical transport and MOKE results of the Cr:Sb$_2$Te$_3$ films. However, in (Cr,V):Sb$_2$Te$_3$, a discrepancy is found between the two measurement techniques, indicating the presence of the Cr$_2$Te$_3$ secondary phase in the sample. For EuS/Bi$_2$Se$_3,$ its interface-induced perpendicular magnetisation is successfully verified using the MOKE microscope. Regarding the ferromagnet/paramagnet [Cr:Sb$_2$Te$_3$/Dy:Bi$_2$Te$_3$]$_{10}$ superlattice film, unexpected exchange bias is observed in the material with an exchange field of up to 0.15 T at 10 K. This finding is supported by a density-functional-theory calculation. Apart from TIs, several ferromagnet/semiconductor heterostructures are investigated for spin transport experiments, including $L1_0$-FePt/MgO/GaAs and [Co/Pt]$_n$/GaAs. None of them show promising magnetisation features for the further pursuit of spin injection into semiconductors. Finally, the surface science of a few magnetic and non-magnetic materials is investigated using low energy electron microscopy (LEEM). A new approach is established to de-oxidise the surface of W(110) substrates at 1800 K, a temperature considerably lower than in the standard W(110) cleaning procedure (2100 K). LEEM also reveals the high-temperature dynamics of the Pt-Si alloy on Si(100) substrates. Following the temperature increment, the Pt-Si alloy goes through the phases of nanowires, islands, and eutectic droplets. This research paves the way towards the future energy-efficient spintronic devices.

description: The superimposed pair of spiral galaxies NGC 3314 offers a unique opportunity to trace the dust properties in a spiral galaxy. We analyze multicolor HST imaging, supported by ground-based near-IR imaging and fiber-array spectroscopy to measure dust extinction in the foreground Sc galaxy NGC 3314A, which is backlit by the Sb system NGC 3314B. We can measure extinctions over a wide range of galactocentric radii in the foreground galaxy, from 0.4-4.5 kpc. In the outer disk, the extinction is strongly localized in discrete dust lanes. These dust features show an extinction curve with a slope close to the Galactic mean (R = 3.5+/-0.3) from 1.6 to 3.8 kpc, with no radial trend. Using the I-K color of the background nucleus, we derive an extinction A(I) = 3.3 through the disk at a projected distance 400 pc from the nucleus of NGC 3314A. The extinction in even the inner disk of NGC 3314A is quite patchy, since background H-alpha emission is detected from all parts of the system. Local anticorrelations between foreground and background line emission demonstrate that the dust is concentrated to star-forming regions, as has been found for the blue light in several systems. Colors of dust lanes in NGC 3314A which are projected only partially against the background disk indicate that the dust scale height in the foreground disk is substantially smaller than that of the stars.

description: We use the electromagnetic stress tensor to describe the elongation of paramagnetic drops in uniform magnetic fields. This approach implies a linear relationship between the shape of the drops and the square of the applied field which we confirm experimentally. We show that this effect scales with the volume and susceptibility of the drops. By using this unified electromagnetic approach, we highlight the potential applications of combining electric and magnetic techniques for controlled shaping of drops in liquid displays, liquid lenses, and chemical mixing of drops in microfluidics.

description: Businesses have a critical role in the transition to a sustainable economy, but this requires them to include social and environmental considerations in their decision-making. However, this creates the problem of resolving competing economic, social and environmental commitments over the long and short term. Scholars have examined this either as an analytical or a cognitive problem, but these approaches may understate the importance of organisational influences. This thesis therefore addresses two questions: first, how do the formal, behavioural and social structures of an organisation interact to influence the inclusion of sustainability criteria in decision-making in incumbent businesses? Second, what are the points of intervention to influence these systems? To answer these questions, I undertook three connected empirical studies, using mixed qualitative methods. These investigations produced four findings. First, including sustainability changes the nature of decisions, leading to four specific archetypes of decisions. Second, the way in which decision-makers resolve the competing commitments in these situations is shaped by a broader framing of the tension between the fundamental logic of the business and the demands of its environment. Third, decision-making is influenced by a series of contextual factors, including the properties of the decision itself; the decision maker(s); the organisation; and the broader environmental context. Fourth, the process of changing decision-making requires a combination of interventions, and a set of foundational capabilities to change. Companies undertaking this type of change find systemic barriers that can only be resolved through co-operation beyond the boundaries of the organisation. These findings have implications for practice. This research contributes to the literature on decision-making and sustainability by presenting a novel classification of decisions and by adding detail to the understanding of contextual factors influencing decision-makers and to paradox theory by demonstrating the influence of paradoxes on decision-making logic and on driving change. This matters: corporate sustainability is an enacted process and unless business decision-making changes, we will not be able to achieve the social and environmental change we need.

description: This research was carried out to determine the effectiveness of imagination stretch teaching strategy in correcting misconceptions of students about the particulate nature of matter in Senior Secondary Schools in Rivers State. A proper understanding of the concept of particulate nature of matter provides a solid foundation for understanding and interpretation of concepts of atoms and molecules which are the invisible microscopic components of all phenomena in the natural world. Quasi-experimental design pretest- posttest control group was adopted using ninety-two (92) Secondary School 3 Chemistry Students from intact class as the sample. A four-tier misconception diagnostic test tagged “Particulate Nature of Matter Misconception Diagnostic Test” developed by the researcher was the instrument used for diagnosis of students’ misconception on the particulate nature of matter. The reliability coefficient of 0.76 of the instrument was established using alpha Cronbach method. Mean, percentages, standard deviation and ANOVA were statistical tools used for data analysis and hypotheses tested at 0.05 level of significance. Wrong answers by approximately 20% or above were considered as misconceptions. From the results, it was discovered that imagination stretch teaching strategy caused a significant reduction in students’ misconceptions about the particulate nature of matter. There was a significant difference in mean score of students’ misconceptions about the particulate nature of matter for the experimental and control groups confirming the effectiveness of imagination stretch teaching strategy in correcting students’ misconceptions. Based on the findings, it was recommended that teachers should adopt conceptual change instructional strategy in teaching abstract chemistry concepts to foster students’ understanding and motivate them to the study chemistry as a subject.

description: We report the first time-series observations of the short outburst of the proposed intermediate polar HT Cam (=RX J0757.0+6306). On 2001 December 29, we detected the object was undergoing a bright outburst at the magnitude of $m_{vis}=12.2$. Following this detection, we started international joint observations through VSNET. The light curve showed a gradual decline for the first 0.5 d. Following this short plateau phase, the rate of decline dramatically increased to more than 4 mag d$^{-1}$. Within 1.5 d from the outburst detection, the object almost declined to the quiescent level. During the rapidly declining phase, long-term modulations with a period of 86 min and strong pulses with a period of 8.6 min were observed. We concluded that 86 min and 8.6 min are the orbital period and the spin period of HT Cam, respectively. By the detection of the spin period, we confirmed the IP classification of HT Cam. However, its outburst behavior rather resembles that of dwarf novae. The discrepancy between the declining rates of the total flux and the pulse flux strongly suggests that the disk instabilities were taking place during the outburst.

Resolving the Large-N Nuclear Potential Puzzle

description: The large $N_c$ nuclear potential puzzle arose because three- and higher-meson exchange contributions to the nucleon-nucleon potential did not automatically yield cancellations that make these contributions consistent with the general large $N_c$ scaling rules for the potential. Here it is proposed that the resolution to this puzzle is that the scaling rules only apply for energy-independent potentials while all of the cases with apparent inconsistencies were for energy-dependent potentials. It is shown explicitly how energy-dependent potentials can have radically different large N behavior than an equivalent energy-independent one. One class of three-meson graphs is computed in which the contribution to the energy-independent potential is consistent with the general large N rules even though the energy-dependent potential is not.

description: Solid-state lightings are becoming the popular choice for lightings due to its higher efficiency, improved colour rendering index and the flexibility of various size and shape. Halide perovskite has tunable colour emission, low disorder and is solution processable making it one of a popular choice as emitters. This thesis demonstrates the versatility of using halide perovskite material in light-emitting diodes. We demonstrate the first working perovskite light-emitting diode at room temperature by introducing thin layer of perovskite emitter which is crucial to confine the inherent free carriers in the material. We show that the 3D lead-halide bulk perovskite is bandgap tunable with emission in the green and red visible spectrum. Light-emitting diodes in the visible spectrum are common however near-infrared emission is a rarity. Lead is a heavy metal which is known for its toxicity. We tackled the issue of toxicity by replacing with tin and demonstrate tunable emission in the near-infrared region. Bulk perovskites have large binding energy which makes it difficult to confine the charges and form radiative recombination which is crucial for emission and efficiency of the device. We move into lower dimensionality perovskites by utilising all-inorganic perovskite nanoplatelets and show emission in the blue region.

description: The Rossi X-ray Timing Explorer has demonstrated that fast X-ray timing can be used to probe strong gravity fields around collapsed objects and constrain the equation of state of dense matter in neutron stars. These studies require extremely good photon statistics. In view of the huge collecting area of its mirrors, XEUS could make a unique contribution to this field. For this reason, it has been proposed to include a fast X-ray timing capability in the focal plane of the XEUS mirrors. We outline the scientific motivation for such a capability, present some sensitivity estimates, and discuss briefly a possible detector implementation.

Relativistic quantum heat engine from uncertainty relation standpoint

description: Established heat engines in quantum regime can be modeled with various quantum systems as working substances. For example, in the non-relativistic case, we can model the heat engine using infinite potential well as a working substance to evaluate the efficiency and work done of the engine. Here, we propose quantum heat engine with a relativistic particle confined in the one-dimensional potential well as working substance. The cycle comprises of two isothermal processes and two potential well processes of equal width, which forms the quantum counterpart of the known isochoric process in classical nature. For a concrete interpretation about the relation between the quantum observables with the physically measurable parameters (like the efficiency and work done), we develop a link between the thermodynamic variables and the uncertainty relation. We have used this model to explore the work extraction and the efficiency of the heat engine for a relativistic case from the standpoint of uncertainty relation, where the incompatible observables are the position and the momentum operators. We are able to determine the bounds (the upper and the lower bounds) of the efficiency of the heat engine through the thermal uncertainty relation.

description: Competing interactions in Quantum Materials induce novel states of matter such as frustrated magnets, an extensive field of research both from the theoretical and experimental perspectives. Here, we show that competing energy scales present in the low-dimensional orbital-selective Mott phase (OSMP) induce an exotic magnetic order, never reported before. Earlier neutron scattering experiments on iron-based 123 ladder materials, where OSMP is relevant, already confirmed our previous theoretical prediction of block-magnetism (magnetic order of the form $\uparrow\uparrow\downarrow\downarrow$). Now we argue that another novel phase can be stabilized in multi-orbital Hubbard models, the {\it block-spiral state}. In this state, the magnetic islands form a spiral propagating through the chain but with the blocks maintaining their identity, namely rigidly rotating. This new spiral state is stabilized without any apparent frustration, the common avenue to generate spiral arrangements in multiferroics. By examining the behaviour of the electronic degrees of freedom, parity breaking quasiparticles are revealed. Finally, a simple phenomenological model that accurately captures the macroscopic spin spiral arrangement is also introduced, and fingerprints for the neutron scattering experimental detection of our new state are provided.

description: Surface plasmon resonance (SPR) biosensors have attracted great attention in scientific research in the past three decades. Extensive studies on the immobilisation of biorecognition elements have been conducted in pursuit of higher sensitivity, but trialled formats have focussed on a thin layer modification next to the plasmon film, which usually requires in situ derivatization. This thesis investigates an ‘off-chip’ immobilisation strategy for SPR biosensing using silica particles and considers the implications of a particle-modified evanescent field on the signal amplitude and kinetics, for an exemplar affinity binding between immobilised IgG and its anti-IgG complement. Submicron silica particles were synthesized as carriers for the bio-recognition elements. They were then immobilised to form a sub-monolayer on the gold film of an SPR biosensor using two methods: thiolsilane coupling and physical adsorption aided by mechanical pressure. The bio-sensitivity towards an antigen/antibody interaction was lower than an SPR biosensor with an alkanethiolate SAM due to the difference in ligand capacity and position in the evanescent field. The binding kinetics of antigen/antibody pair was found to follow the Langmuir model closely in a continuous flow configuration but was heavily limited by the mass transport from the bulk to the sensor surface in a stop-flow configuration. A packed channel configuration was designed with larger gel particles as ligand carriers, packed on top of a gold film to create a column-modified SPR biosensor. This sensor has comparable bio-sensitivity to the previous sub-monolayer particle-modified systems, but the binding and dissociation of the analyte was heavily dependent on mass transport and binding equilibria across the column. A bi-directional diffusion mechanism was proposed based on a two-compartment mass transport model and the expanded model fitted well with the experimental data. The column-modified sensor was also studied by SPR imaging and analyte band formation was observed and analysed. Using the lateral resolution, a multiplexing particle column configuration was explored, and its potential in distinguishing a multicomponent analyte.

description: In France, the increasing weight of jobs in services for the populations makes these service sectors an essential component of contemporary rural economics. Their development, which in the last decade asserted itself in the periurban municipalities and in predominantly rural areas, contributes significantly to the economic dynamics of the rural and periurban areas, with public services playing a central role. This rapid development has brought together the shops and services for the populations they serve; their accessibility, however, depends on the nature of the facilities and on their rationales of location.
On quantum and approximate privacy

description: This paper studies privacy and secure function evaluation in communication complexity. The focus is on quantum versions of the model and on protocols with only approximate privacy against honest players. We show that the privacy loss (the minimum divulged information) in computing a function can be decreased exponentially by using quantum protocols, while the class of privately computable functions (i.e., those with privacy loss 0) is not enlarged by quantum protocols. Quantum communication combined with small information leakage on the other hand makes certain functions computable (almost) privately which are not computable using either quantum communication without leakage or classical communication with leakage. We also give an example of an exponential reduction of the communication complexity of a function by allowing a privacy loss of $o(1)$ instead of privacy loss 0.

description: We construct the moduli cone stack $\mathfrac{M}_\eta^\text{trop}$ of tropical \'{e}tale covers (i.e., coverings of twisted tropical curves). We define the tropical intersection theory on $\mathfrac{M}_\eta^\text{trop}$ and show that the tropical intersection theory agrees with the intersection theory on the moduli stack $\bar{\mathfrac{M}}_\eta$ of \'{e}tale covers (i.e., coverings of twisted algebraic curves). We apply the tropical intersection theory on $\mathfrac{M}_\eta^\text{trop}$ to calculate the intersection numbers of Psi-classes on the moduli space $\bar{\mathfrac{M}}_{g,n}$ of $n$-marked genus $g$ curves. We also define the moduli stack $\mathfrac{M}_\eta^\text{log}$ of logarithmic \'{e}tale covers and describe the tropicalization map from $\mathfrac{M}_\eta^\text{log}$ to the Artin fan of $\mathfrac{M}_\eta^\text{trop}$.

description: We investigate the cosmological dynamics of nonlocally corrected gravity involving a function of the inverse d'Alembertian acting on the Gauss-Bonnet term. Casting the dynamical equations in local form, we derive the reconstruction procedure. We find conditions on the model parameters that are sufficient for the existence of de Sitter solutions and obtain these solutions explicitly.
