description: The coherence factor (CF) is defined as the ratio of coherent power to incoherent power received by the radar aperture. The incoherent power is computed by the multi-antenna receiver based on only the spatial variable. In this respect, it is a one-dimensional (1-D) CF, and thereby the image sidelobes in down-range cannot be effectively suppressed. We propose a two-dimensional (2-D) CF by supplementing the 1-D CF by an incoherent sum dealing with the frequency dimension. In essence, we employ both spatial diversity and frequency diversity which, respectively, enhance imaging quality in cross range and range. Simulations and experimental results are provided to demonstrate the performance advantages of the proposed approach.

description: While the Gibbs states of spin glass models have been noted to have an erratic dependence on temperature, one may expect the mean over the disorder to produce a continuously varying ``quenched state''. The assumption of such continuity in temperature implies that in the infinite volume limit the state is stable under a class of deformations of the Gibbs measure. The condition is satisfied by the Parisi Ansatz, along with an even broader stationarity property. The stability conditions have equivalent expressions as marginal additivity of the quenched free energy. Implications of the continuity assumption include constraints on the overlap distribution, which are expressed as the vanishing of the expectation value for an infinite collection of multi-overlap polynomials. The polynomials can be computed with the aid of a "real"-replica calculation in which the number of replicas is taken to zero.

description: Motivated by the recent gravitational wave detection by the LIGO-VIRGO observatories, we study the Love number and dimensionless tidal polarizability of highly magnetized stars. We also investigate the fundamental quasi-normal mode of neutron stars subject to high magnetic fields. To perform our calculations we use the chaotic field approximation and consider both nucleonic and hyperonic stars. As far as the fundamental mode is concerned, we conclude that the role played by the constitution of the stars is far more relevant than the intensity of the magnetic field and if massive stars are considered, the ones constituted by nucleons only present frequencies somewhat lower than the ones with hyperonic cores, a feature that can be used to point out the real internal structure of neutron stars. Moreover, our studies clearly indicate that strong magnetic fields play a crucial role in the deformability of low mass neutron stars, with possible consequences on the interpretation of the detected gravitational waves signatures.

description: We demonstrate how a hierarchical network comprising a number of compliant reference stations and a much larger number of low-cost sensors can deliver reliable high temporal-resolution ozone data at neighbourhood scales. The framework, demonstrated originally for a smaller scale regional network deployed in the Lower Fraser Valley, BC was tested and refined using two much more extensive networks of gas-sensitive semiconductor-based (GSS) sensors deployed at neighbourhood scales in Los Angeles: one of ~20 and one of ~45 GSS ozone sensors. Of these, ten sensors were co-located with different regulatory measurement stations, allowing a rigorous test of the accuracy of the algorithms used for off-site calibration and adjustment of low cost sensors. The method is based on adjusting the gain and offset of the low-cost sensor to match the first two moments of the probability distribution of the sensor result to that of a proxy: a calibrated independent measurement (usually derived from regulatory monitors) whose probability distribution evaluated over a time that emphasizes diurnal variations is similar to that at the test location. The regulatory measurement station physically closest to the low-cost sensor was a good proxy for most sites. The algorithms developed were successful in detecting and correcting sensor drift, and in identifying locations where geographical features resulted in significantly different patterns of ozone variation due to the relative dominance of different dispersion, emission and chemical processes. The entire network results show very large variations in ozone concentration that take place on short time- and distance scales across the Los-Angeles region. Such patterns were not captured by the more sparsely distributed stations of the existing regulatory network and demonstrate the need for reliable data from dense networks of monitors.

title: The Therapeutic Potential of mTOR signalling Pathway as Drug Target in Human Colorectal Cancer

Subjects: subject: Mammalian target of rapamycin (mTOR)

subject: mTOR inhibitors

description: The mammalian target of rapamycin (mTOR), a downstream effector of PI3K/Akt signalling, is a critical regulator of cellular processes in response to oncogenic signals. In mammalian cells, mTOR exists in 2 large physically and functionally distinct signalling complexes, i.e.: mTORC1 and mTORC2. Each complex has its own set of downstream targets, which modulate cellular growth, proliferation, and survival in normal cells and cancer. Deregulation of mTOR signalling often occurs in a variety of human malignant diseases, making it a validated target in the development of treatments for cancer. In colorectal cancer, both in vitro and in vivo studies have demonstrated various roles for different genes, including those related to the mTOR pathway in the pathogenesis of cancer. Clinical trials have already started to examine the feasibility of mTOR inhibitors as therapeutic drugs for cancer. In this study, our objectives were firstly to investigate the expression levels of mTOR in human pathological samples of colorectal cancer and subsequently investigate the effect of mTOR inhibitors in human colorectal cancer cell lines. Finally, the study sought to identify potential miRNAs with putative targets in the mTOR pathway.

description: Wolbachia are maternally transmitted endosymbionts that naturally infect approximately 40% of all insect species and impose a range of phenotypic effects upon their hosts, including feminization, parthenogenesis, cytoplasmic incompatibility (CI) and male-killing. The genetic basis and mechanisms of these phenotypes remain mostly undetermined. Investigating new strains of Wolbachia can provide important insight into the biology of the symbiosis. In Drosophila pandora, two distinct Wolbachia strains co-exist to manipulate host reproduction, which are wPanCI (causing CI) and wPanMK (causing male-killing) respectively. Furthermore, wPanMK seems to rescue CI induced by wPanCI. To understand the molecular basis of CI and male-killing, genome sequencing and comparison projects with wPanCI and wPanMK were undertaken. To investigate the mechanism of CI, both cifA and cifB were compared among wMel, wPanCI and wPanMK; the cifB protein in wPanMK is truncated and has one base pair deletion, which indicating that it may be non-functional in wPanMK. The similar cifA gene in wPanCI and wPanMK and wPanMK’s ability to recue CI provide evidence for a previously toxin (cifB)-antitoxin (cifA) model; however, wPanMK cannot induce CI due to the mutation of cifB provide evidence that CI mechanism need both cifA and cifB. For male-killing mechanism, a spaid gene has been described to affect the male-killing in another endosymbiotic bacterium, Spiroplasma poulsonii. By comparing a spaid-like protein in different Wolbachia strains, a common structure with a protein-protein interaction domain and a cell death domain has been described and a spaid-like gene, wPanMK_288, has been found in wPanMK, which may be the manipulator gene to induce the male-killing. The study explains both two models of CI mechanism and provides a common structure and suggests putative genes for the expression of MK in Wolbachia and Spiroplasma.

In particular, a toy model for a three-source "baryon" is constructed and investigated analytically and numerically for various choices of interactions. VPython is used to visualize the nontrivial color charge dynamics. The treatment should be accessible to undergraduate students who have taken a first course in quantum mechanics, and suggestions for independent student projects are proposed.

description: The integration of Large Language Models (LLMs) with Learning Management Systems (LMSs) has the potential to enhance task automation and accessibility in education. However, hallucination where LLMs generate inaccurate or misleading information remains a significant challenge. This study introduces the Dynamic Course Content Integration (DCCI) mechanism, which dynamically retrieves and integrates course content and curriculum from Canvas LMS into the LLM-powered assistant, Ask ME. By employing prompt engineering to structure retrieved content within the LLM's context window, DCCI ensures accuracy, relevance, and contextual alignment, mitigating hallucination. To evaluate DCCI's effectiveness, Ask ME's usability, and broader student perceptions of AI in education, a mixed-methods approach was employed, incorporating user satisfaction ratings and a structured survey. Results from a pilot study indicate high user satisfaction (4.614/5), with students recognizing Ask ME's ability to provide timely and contextually relevant responses for both administrative and course-related inquiries. Additionally, a majority of students agreed that Ask ME's integration with course content in Canvas LMS reduced platform-switching, improving usability, engagement, and comprehension. AI's role in reducing classroom hesitation and fostering self-directed learning and intellectual curiosity was also highlighted. Despite these benefits and positive perception of AI tools, concerns emerged regarding over-reliance on AI, accuracy limitations, and ethical issues such as plagiarism and reduced student-teacher interaction. These findings emphasize the need for strategic AI implementation, ethical safeguards, and a pedagogical framework that prioritizes human-AI collaboration over substitution.

description: Combining both vertical and in-plane two-dimensional (2D) heterostructures opens up the possibility to create an unprecedented architecture using 2D atomic layer building blocks. The thermal transport properties of such mixed heterostructures, critical to various applications in nanoelectronics, however, have not been thoroughly explored. Herein, we construct two configurations of multilayer in-plane graphene/hexagonal boron nitride (Gr/h-BN) heterostructures (i.e. mixed heterostructures) via weak van der Waals (vdW) interactions and systematically investigate the dependence of their interfacial thermal conductance (ITC) on the number of layers using non-equilibrium molecular dynamics (NEMD) simulations. The computational results show that the ITC of two configurations of multilayer in-plane Gr/h-BN heterostructures (MIGHHs) decrease with increasing layer number n and both saturate at n = 3. And surprisingly, we find that the MIGHH is more advantageous to interfacial thermal transport than the monolayer in-plane Gr/h-BN heterostructure, which is in strong contrast to the commonly held notion that the multilayer structures of Gr and h-BN suppress the phonon transmission. The underlying physical mechanisms for these puzzling phenomena are probed through the analyses of heat flux, temperature jump, stress concentration factor, overlap of phonon vibrational spectra and phonon participation ratio. In particular, by changing the stacking angle of MIGHH, a higher ITC can be obtained due to the thermal rectification behavior. Furthermore, we find that the ITC in MIGHH can be well-regulated by controlling the coupling strength between layers. Our findings here are of significance for understanding the interfacial thermal transport behaviors of multilayer in-plane Gr/h-BN heterostructure, and are expected to attract extensive interest in exploring its new physics and applications.

We find that states with winding number larger than a critical one are unstable, in the sense that they decay to states with smaller winding number. The transition from Phase to Defect Turbulence is interpreted as an ergodicity breaking transition which occurs when the range of stable winding numbers vanishes. Asymptotically stable states which are not spatio-temporally chaotic are described within the PT regime of nonzero winding number.

description: The SIGCHI and Social Computing research communities have been at the forefront of online safety efforts for youth, ranging from understanding the serious risks youth face online to developing evidence-based interventions for risk protection. Yet, to bring these efforts to bear, we must partner with practitioners, such as industry stakeholders who know how to bring such technologies to market, and youth service providers who work directly with youth. Therefore, we interviewed 33 stakeholders in the space of youth online safety, including industry professionals (n=12), youth service providers (n=11), and researchers (n=10) to understand where their visions toward working together to protect youth online converged and surfaced tensions, as well as how we might reconcile conflicting viewpoints to move forward as one community with synergistic expertise on how to change the current sociotechnical landscape for youth online safety. Overall, we found that non-partisan leadership is necessary to chart actionable, equitable goals to facilitate collaboration between stakeholders, combat feelings of isolation, and foster trust between the stakeholder groups. Based on these findings, we recommend the use of open-innovation methods with their inherent transparency, federated governance models, and clear but inclusive leadership structures to promote collaboration between youth online safety stakeholders. We propose the creation of an open-innovation organization that unifies the diverse voices in youth online safety to develop open-standards and evidence-based design patterns that centralize otherwise fragmented efforts that have fallen short of the goal of effective technological solutions that keep youth safe online.

description: Gaussian Processes (GPs) are powerful kernelized methods for non-parameteric regression used in many applications. However, their use is limited to a few thousand of training samples due to their cubic time complexity. In order to scale GPs to larger datasets, several sparse approximations based on so-called inducing points have been proposed in the literature. In this work we investigate the connection between a general class of sparse inducing point GP regression methods and Bayesian recursive estimation which enables Kalman Filter like updating for online learning. The majority of previous work has focused on the batch setting, in particular for learning the model parameters and the position of the inducing points, here instead we focus on training with mini-batches. By exploiting the Kalman filter formulation, we propose a novel approach that estimates such parameters by recursively propagating the analytical gradients of the posterior over mini-batches of the data. Compared to state of the art methods, our method keeps analytic updates for the mean and covariance of the posterior, thus reducing drastically the size of the optimization problem. We show that our method achieves faster convergence and superior performance compared to state of the art sequential Gaussian Process regression on synthetic GP as well as real-world data with up to a million of data samples.

Essays on Leadership Selection and Public Goods Provision in Self-Help Organizations
Creators: Grossman, Guy
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Political science
subject: FOS: Political science

description: This dissertation examines the relationship between leadership selection and public goods provision in self-help organizations. Leadership selection is defined as the rules for selecting leaders, as well as the factors that determine the quality of the leadership class. Self-help organizations are defined as relatively small-size voluntary groups that are created to provide goods and services to members and that select their leader via democratic procedures. Examples include micro-lending and micro-insurance groups, common-pool resource groups, women and artisan cooperatives and farmer associations. The dissertation focuses on Uganda's recent largest development project: the Agriculture Productivity Enhancement Project (APEP). USAID funded, APEP's stated goal is to expand rural economic opportunities by supporting the transition of smallholder producers into commercial farming. During the project's lifespan (2005-2009), APEP helped about 60,000 small-scale producers to organize into over 200 farmer associations (i.e. cooperatives). Importantly, the success of these farmer associations in overcoming social dilemmas and in providing goods and services to their members, varied tremendously. Why are some groups more successful than others in overcoming the social dilemmas inherent in public goods production? To explain this variation, the dissertation uses a range of disciplinary perspectives --- drawn mainly from political science, economics, social psychology and sociology --- as well as a diverse set of methodological tools.

description: The ionising stellar populations of eleven HII regions in the spiral galaxies: NGC628, NGC925, NGC1232 and NGC1637, all of them reported to have solar or oversolar abundances according to empirical calibrations, have been analysed using stellar population synthesis models. Four of the observed regions in the sample, show features which indicate the presence of a population of Wolf-Rayet (WR) stars with ages between 2.3 and 4.1 Myr. This population is sufficient to explain the emission line spectrum of the low metallicity region H13 in NGC628. This is not the case for the rest of the regions for which a second ionising population is required to simultaneously reproduce both the WR features and the emission line spectrum. For two of the regions showing WR features, no consistent solution is found, since the population containing WR stars produces a spectral energy distribution which is too hard to explain the emission of the gas. Several solutions are proposed to solve this problem.

description: This paper presents a real-time non-probabilistic detection mechanism to detect load-redistribution (LR) attacks against energy management systems (EMSs). Prior studies have shown that certain LR attacks can bypass conventional bad data detectors (BDDs) and remain undetectable, which implies that presence of a reliable and intelligent detection mechanism to flag LR attacks, is imperative. Therefore, in this study a detection mechanism to enhance the existing BDDs is proposed based on the fundamental knowledge of the physics laws in the electric grid. A greedy algorithm, which can optimize the core LR attack problems, is presented to enable a fast mechanism to identify the most sensitive locations for critical assets. The main contribution of this detection mechanism is leveraging of power systems domain insight to identify an underlying exploitable structure for the core problem of LR attack problems, which enables the prediction of the attackers' behavior. Additional contribution includes the ability to combine this approach with other detection mechanisms to increase their likelihood of detection. The proposed approach is applied to 2383-bus Polish test system to demonstrate the scalability of the greedy algorithm, and it solved the attacker's problem more than 10x faster than a traditional linear optimization approach.

description: In order to obtain a better understanding of hydrate plug formation mechanism in natural gas pipelines, formation and growth of hydrate layer within a rectangular channel formed by brass bottom and top surfaces and an insulated inner and an outer surface of transparent polycarbonate tube was studied experimentally. A gas mixture of 90 % methane balanced with propane was supplied at specified flow rates while the humidity and temperature of the supply gas was controlled at desired values using bubble type saturators and heat exchangers placed in series. Hydrate formation occurred along the top and bottom brass surfaces maintained at temperatures below equilibrium hydrate formation temperature, while the transparent tube served as window for visual observation. A series of carefully controlled laboratory experiments were performed to reveal the shape of porous hydrate layer under different combinations of under-cooling and moisture concentrations. The observed transient characteristics of hydrate layer profiles will provide important data that can be used for validation of numerical models to predict hydrate plugging of natural gas pipelines.

description: Layered quasi two dimensional systems have garnered huge interest both in the advancement of technology and in understanding emergent physics such as unconventional superconductivity, topological phases. In particular, the study of topological properties in some bilayer systems like transition metal chalcogenides and iridates has been the point of attraction due to comparatively strong spin orbit coupling of transition metal ions. In this paper, we analyze the topological phases induced by the interplay of electron correlation and spin orbit coupling in different stacking orders of bilayer honeycomb lattice at quarter filling. Considering the two most common stacking orders, AA and bernel (AB) stacking, we show that the stacking order plays a crucial role in the topological phase transitions of the bilayer interacting system. For AA stacking case, the system realizes quantum spin Hall insulator in the presence (absence) of time reversal symmetry and magnetically ordered insulator. For bernel stacking case, however, additional phases such as charge ordered normal insulator or Chern insulator with both charge and magnetic order can be stabilized. Based on our analysis, we discuss the scope of experimental realization in bilayers of transition metal chalcogenides.

description: Tetra-n-Butyl Ammonium Bromide (TBAB) forms semi-clathrate hydrates which can incorporate small gas molecules, such as methane and nitrogen at ambient temperatures and atmospheric pressure. Such favourable stability conditions, combined with ease of formation could make semi-clathrates particularly attractive for a large variety of applications. These hydrates have recently been investigated for their use in the separation of gases, and it is proposed that the same technology could potentially be used for storage and transportation of gases. To evaluate the feasibility of using TBAB hydrates for separation and storage purposes, an extensive test programme was conducted to determine: phase stability of the semi-clathrates, gas storage capacity, and composition of the stored gas. The results show that TBAB semi-clathrates have very favourable stability conditions. They can store considerable quantities of gas, and favour small molecules in their structures. These experiments suggest that semi-clathrate hydrates, such as TBAB, could have a significant potential as an alternative for industrial separation, storage, and transportation of natural gas.

description: Consider an unitary highest weight representation of a group U(p,q) in holomorphic functions on the symmetric space U(p,q)/U(p)\times U(q). Consider its restriction ρto the subgroup O(p,q). This restriction has a complicated spectrum consisting of representations having different types. We construct a decomposition of ρto a finite direct sum of representations τ_j such that each summand τ_j has spectrum consisting of one-type representations. Our tool is theorems about restrictions of holomorphic functions on Cartan domain U(p,q)/U(p)\times U(q) to submanifolds of the boundary. We also obtain Plancherel formula for this restriction.

description: Secondary metabolites and their derivatives from microorganisms are a source of many important drugs. Indeed almost half of the antibiotics in the market are actinomycetes sourced natural products. However, advances in genome sequencing have revealed that actinomycetes are capable of producing still a far greater number of metabolites and potential drugs. The machinery for making the majority of secondary metabolites is silent when actinomycetes are grown under standard culture conditions. Chapters 2 and 3 of this thesis focused on two different approaches to de- silence bacterial cryptic genes. A method involving 1H NMR fingerprinting was used to compare and investigate the metabolic profile of bacteria. This method is more comprehensive than the traditional analytical techniques such as LC-PDA and LC- MS. Metabolite profiling by LC-PDA and LC-MS is dependent either on the existence of a chromophore (PDA detection) or the ability of a compound to be ionised (MS detection) and might not detect all of the changes of the secondary metabolome. However, all organic compounds containing a proton are easily detected by NMR. Naturally microbes are in contact with different organisms. They produce secondary metabolites to communicate within or between species and also to defend themselves. One strategy to de-silent the cryptic genes is to mimic the environment and co-culture the microbes.

description: What is the correct way to respond to newly acquired information? What methods for updating beliefs and other attitudes are rational? And what makes them rational? This dissertation is a collection of independent essays, each of which addresses these questions. Among other things, I investigate the extent to which Bayesian learning can be considered objective, the circumstances in which rational learning reduces uncertainty and produces consensus, whether rational learning is compatible with disagreement and polarization, and the relationship between long-run and short-run norms for learning.

description: We show that, in the semiclassical limit and whenever the elements of the Hamiltonian matrix are random enough, the eigenvectors of strongly chaotic time-independent systems in ordered bases can on average be exponentially localized across the energy shell and decay faster than exponentially outside the energy shell. Typically however, matrix elements are strongly correlated leading to deviations from such behavior.

description: Across three essays, I explore how modern statistical machine learning approaches can be used to glean novel marketing insights from data and to facilitate data-driven decision support in new domains. In particular, I draw on Bayesian nonparametrics, deep generative modeling, and modern Bayesian computational techniques to  develop new methodologies that enhance standard marketing models, address modern challenges in data-driven marketing, and, as I show through applications to real world data, glean new, managerially relevant insights. Substantively, my work addresses issues in customer base analysis, the estimation of consumer preferences, and brand identity and logo design. In my first essay, I address how multi-product firms can understand and predict customer purchasing dynamics in the presence of partial information, by developing a Bayesian nonparametric model for customer purchasing activity. This framework yields an interpretable, model-based dashboard, which can be used to predict future activity, and guide managerial decision making. In my second essay, I explore the flexible modeling of customer brand choice dynamics using a novel form of heterogeneity, which I term dynamic heterogeneity. Specifically, I develop a novel doubly hierarchical Gaussian process framework to flexibly model how the preferences of individual customers evolve relative to one another over time, and illustrate the utility of the framework with an application to purchasing during the Great Recession. Finally, in my third essay, I explore how data and models can inform firms' aesthetic choices, in particular the design of their logos. To that end, I develop image processing algorithms and a deep generative model of brand identity that links visual data with textual descriptions of firms and brand personality perceptions, which can be used for understanding design standards, ideation, and ultimately, data-driven design.
