Encrypted Search: Enabling Standard Information Retrieval Techniques for Several New Secure Index Types While Preserving Confidentiality Against an Adversary With Access to Query Histories and Secure Index Contents
Creators: name: Towell, Alexander
Publisher: name: Zenodo
Year: 2015

description: Encrypted Search is a way for a client to store searchable documents on untrusted systems such that the untrusted system can obliviously search the documents on the client's behalf, i.e., the untrusted system does not know what the client is searching for nor what the documents contain. Several new secure index types are designed, analyzed, and implemented. We analyze them with respect to several performance measures: confidentiality, time complexity, space complexity, and search retrieval accuracy. In order to support rank-ordered search, the secure indexes store frequency and proximity information. We investigate the risk this additional information poses to confidentiality and explore ways to mitigate said risk. Separately, we also simulate an adversary who has access to a history of encrypted queries and design techniques that mitigate the risk posed by this adversary.

description: Three-nucleon force and continuum play important roles in reproducing the properties of atomic nuclei around driplines. Therefore it is valuable to build up a theoretical framework where both effects can be taken into account to solve the nuclear Schrödinger equation. To this end, in this letter, we have expressed the chiral three-nucleon force within the continuum Berggren representation, so that bound, resonant and continuum states can be treated on an equal footing in the complex-momentum space. To reduce the model dimension and computational cost, the three-nucleon force is truncated at the normal-ordered two-body level and limited in the $sd$-shell model space, with the residual three-body term being neglected. We choose neutron-rich oxygen isotopes as the test ground because they have been well studied experimentally, with the neutron dripline determined. The calculations have been carried out within the Gamow shell model. The quality of our results in reproducing the properties of oxygen isotopes around the neutron dripline shows the relevance of the interplay between three-nucleon force and the coupling to continuum states. We also analyze the role played by the chiral three-nucleon force, by dissecting the contributions of the $2π$ exchange, $1π$ exchange and contact terms.

description: We have explored the influence of deposition pressure and temperature on the growth of BiFeO3 thin films by pulsed laser deposition onto (001)-oriented SrTiO3 substrates. Single-phase BiFeO3 films are obtained in a region close to 10-2 mbar and 580C. In non-optimal conditions, X-ray diffraction reveals the presence of Fe oxides or of Bi2O3. We address the influence of these parasitic phases on the magnetic and electrical properties of the films and show that films with Fe2O3 systematically exhibit a ferromagnetic behaviour, while single-phase films have a low bulk-like magnetic moment. Conductive-tip atomic force microscopy mappings also indicate that Bi2O3 conductive outgrowths create shortcuts through the BiFeO3 films, thus preventing their practical use as ferroelectric elements in functional heterostructures.

description: Augmentation of disease diagnosis and decision-making in healthcare with machine learning algorithms is gaining much impetus in recent years. In particular, in the current epidemiological situation caused by COVID-19 pandemic, swift and accurate prediction of disease diagnosis with machine learning algorithms could facilitate identification and care of vulnerable clusters of population, such as those having multi-morbidity conditions. In order to build a useful disease diagnosis prediction system, advancement in both data representation and development of machine learning architectures are imperative. First, with respect to data collection and representation, we face severe problems due to multitude of formats and lack of coherency prevalent in Electronic Health Records (EHRs). This causes hindrance in extraction of valuable information contained in EHRs. Currently, no universal global data standard has been established. As a useful solution, we develop and publish a Python package to transform public health dataset into an easy to access universal format. This data transformation to an international health data format facilitates researchers to easily combine EHR datasets with clinical datasets of diverse formats. Second, machine learning algorithms that predict multiple disease diagnosis categories simultaneously remain underdeveloped. We propose two novel model architectures in this regard. First, DeepObserver, which uses structured numerical data to predict the diagnosis categories and second, ClinicalBERT_Multi, that incorporates rich information available in clinical notes via natural language processing methods and also provides interpretable visualizations to medical practitioners. We show that both models can predict multiple diagnoses simultaneously with high accuracy.

description: In this Letter we interpret the Y(4260), a state recently discovered by the BaBar Collaboration that has a mass within the range of conventional charmonium states, as having a molecular-state structure. In our scheme this molecular-like state is not constructed out of two-quark mesons, but rather out of baryons, i.e., the Y(4260) is a baryonium state. With this interpretation, the unusual measured properties of the Y(4260) are easily understood and some further peculiar decay characteristics are predicted.

Subjects: Environmental Economics and Policy

description: A dynamic framework is presented for analyzing regulations affecting the use of spoilage-reducing inputs with potential negative environmental effects, such as pesticides, growth regulators, chemical preservatives, and irradiation. Such regulations change intertemporal consumption patterns as well as total output. Consumers may benefit from restrictions on storage technology, giving them a reason to support regulation even when it may not be warranted to correct environmental externalities. Static analyses do not take into account changes in intertemporal consumption, and thus may give misleading depictions of the effects of imposing new regulations. Implications of the framework for development and trade policy are discussed, as are extensions to cases of uncertainty and multiple time periods.

description: The problem of evaluating the information associated with Fredholm integral equations of the first kind, when the integral operator is self-adjoint and compact, is considered here. The data function is assumed to be perturbed gently by an additive noise so that it still belongs to the range of the operator. First we estimate upper and lower bounds for the epsilon-capacity (and then for the metric information), and explicit computations in some specific cases are given; then the problem is reformulated from a probabilistic viewpoint and use is made of the probabilistic information theory. The results obtained by these two approaches are then compared.

description: The costs of deer-vehicle collisions (DVCs) nationwide are estimated to be in excess of $1 billion annually. In this study, factors contributing to the abundance of DVCs are identified and the potential effectiveness of various deer management strategies in reducing DVCs is investigated. The added benefits of such strategies are also evaluated in a bioeconomic context by comparing alternative outcomes achievable from implementing DVC mitigation techniques. Focusing on Ohio, results suggest potentially large economic gains exist from reducing DVCs, especially with strategies that combine both deer management schemes and DVC mitigation techniques.

description: One of the greatest challenges facing agriculture for the foreseeable future is to resolve conflicts caused by a growing competition for the services of the soil, water, and other natural resources on which agriculture depends-driven by growing demands for food, fiber, and for nonagricultural services these resources provide. To meet this challenge, research is needed which is integrated across the relevant sciences to better understand and predict the properties of agricultural production systems in all of the dimensions that have come to be represented by the concept of sustainability. If we were to achieve this capability to analyze agriculture as a managed ecosystem, it would be possible to move beyond the current regime of agricultural policies, driven largely by interest-group politics, toward science-based policies that recognize the tradeoffs associated with competing uses of natural resources.

description: One-step-ahead forecasts of quarterly beef, pork, and poultry production are examined and evaluated based on traditional criteria for optimality-efficiency and unbiasedness-as well as their performance versus a univariate time-series model. However, traditional regression methodology for evaluating forecasts is avoided due to interpretive issues. Instead, an empirical framework focusing on forecast errors in employed. Results suggest USDA forecasts are unbiased, but generally not efficient. That is, they do not fully incorporate the information contained in past forecasts. Moreover, USDA's predictions do not encompass all the information contained in forecasts generated by simple time-series models. Thus, practitioners who use the USDA forecasts may want to supplement them with time-series forecasts.

description: Water management and reuse at the field level are analyzed under saline, limited drainage conditions. A function relating crop yield and deep percolation flows to applied water and salinity concentration is developed. This function fits simulated data well and is tractable for theoretical and empirical analysis of irrigation economics. With a single irrigation source, irrigation water for cotton and tomatoes at first increases and the decreases with salt concentration. Drain-water reuse is found to be an efficient strategy in events of high surface-water prices and costly solutions to drainage-related environmental problems. However, blending freshwater and drainage appears plausible only under surface water scarcity

Identification of novel genetic alterations in non-small cell lung cancer progression
Creators: name: Siwoski, Arek
Publisher: name: University of British Columbia
Year: 2009

description: To improve the survival rate in lung cancer, novel molecular targets that facilitate early detection and intervention are required. This thesis aims at screening multiple loci from distinct stages of lung cancer using genome scanning methods to identify frequently occurring genetic alterations that could potentially reveal novel regions of chromosomal instability. Due to the tissue heterogeneity in biopsies, tissue microdissection is necessary to isolate specific populations of cells from formalin-fixed, paraffin-embedded tissues representing progression stages of lung cancer. Since some of the commonly used histological stains such as Hematoxylin & Eosin have been shown to degrade DNA due to their acidic nature, a panel of histological stains have been tested for minimal degradative effect on DNA. To work with the minute quantities of DNA recovered from premalignant lesions, we have adapted a Randomly Amplified Polymorphic DNAPolymerase Chain Reaction (RAPD-PCR) assay to assess the quality of DNA extracted from the microdissected specimens, as well as a Southern hydridization assay to assess DNA quantity. DNA samples have been extracted from normal epithelial, hyperplastic, dysplastic, CIS and invasive carcinoma cells originated from 41 patients at various bronchial sites. DNA yield varied from 20ng to 2000ng depending on the amount of cells available in each lesion. Typical molecular techniques such as loss of heterozygosity (LOH) assay, DNA microarrays and fluorescent in situ hybridization (FISH) require large amounts of DNA to detect genomic changes. Using RAPD-PCR as a multi-loci fingerprinting technique, it is possible to screen for genetic alterations using minute DNA samples from microdissected specimens. RAPD-PCR involves simultaneous amplification of genomic DNA at multiple loci using short oligonucleotide primers. Gains and losses of PCR signals that occur in multiple patients identify regions potentially harboring candidate tumour suppressor genes or oncogenes. Our results show that twelve patients showed a gain of PCR signal in carcinoma in situ (CIS) tissue compared to normal tissue. By cloning, sequencing, and mapping the fragments, the recurring gains in PCR signal in multiple patients corresponded to regions at 8q24.3 (6/17), lq23.3 (2/18), 5q33.1 (2/16), and 7q36.2 (2/15). Microsatellite markers were chosen surrounding all four regions, however, due to minimal amounts of patient DNA, only regions 8q24.3 and 7q36.2 were verified for allelic imbalance in multiple patients using LOH. The groundwork has been laid for others to define the boundaries of these unstable regions as both regions contain many potential oncogenes and tumor suppressor genes.

description: Environmental concerns linked to hog production are growing in the United States, Canada, and the European Union. New regulations controlling animal manure management are being imposed to address these concerns. This study determines that potential increases in U.S. and Canadian environmental regulation would have minimal effects on the relative competitiveness of pork exports for these countries. By contrast, more stringent European Union regulations have potential to significantly reduce EU competitiveness and contribute to the trend of increasing export market share for U.S. and Canadian pork products.

description: An optimal advertising investment rule is derived for a vertically related, competitive market with traded final and raw goods and processing sector characterized by variable proportions technology and nonconstant returns to scale. An equilibrium displacement framework incorporating conditional factor demands is used to account for the elasticity of substitution between agricultural and nonagricultural inputs to the marketing channel. Simulation for the Canadian beef industry in the post-WTO environment demonstrates how optimal advertising intensity ranges between 0.05% and 0.22% of farm-level market revenue.
Confined and ejective eruptions of kink-unstable flux ropes

Year: 2005

description: The ideal helical kink instability of a force-free coronal magnetic flux rope, anchored in the photosphere, is studied as a model for solar eruptions. Using the flux rope model of Titov & Demoulin (1999} as the initial condition in MHD simulations, both the development of helical shape and the rise profile of a confined (or failed) filament eruption (on 2002 May 27) are reproduced in very good agreement with the observations. By modifying the model such that the magnetic field decreases more rapidly with height above the flux rope, a full (or ejective) eruption of the rope is obtained in very good agreement with the developing helical shape and the exponential-to-linear rise profile of a fast coronal mass ejection (CME) (on 2001 May 15). This confirms that the helical kink instability of a twisted magnetic flux rope can be the mechanism of the initiation and the initial driver of solar eruptions. The agreement of the simulations with properties that are characteristic of many eruptions suggests that they are often triggered by the kink instability. The decrease of the overlying field with height is a main factor in deciding whether the instability leads to a confined event or to a CME.

description: ABSTRACT: People who take on challenges and persevere longer are more likely to succeed in life. But individuals often avoid exerting effort, and there is limited experimental research investigating whether we can learn to value effort. Because existing research focuses on enhancing cognitive performance rather than increasing the value of effort, it also remains unclear whether individuals can learn to care more about challenging themselves than performing well. We developed a paradigm to test an intuitive idea: that people can learn to value effort and will seek effortful challenges if directly incentivized to do so. Critically, we dissociate the effects of rewarding people for choosing effortful challenges and performing well. We predict that rewarding effortful choices will increase willingness to engage in challenging tasks. We also predict near- and far-transfer effects, as reflected in changes in preferences on unrewarded and unrelated tasks.

description: We analyze the transport and deposition behavior of dilute microparticles in turbulent Rayleigh-Bénard convection. Two-dimensional direct numerical simulations were carried out for the Rayleigh number ($Ra$) of $10^{8}$ and the Prandtl number ($Pr$) of 0.71 (corresponding to the working fluids of air). The Lagrangian point particle model was used to describe the motion of microparticles in the turbulence. Our results show that the suspended particles are homogeneously distributed in the turbulence for the Stokes number ($St$) less than $10^{-3}$, and they tend to cluster into bands for $10^{-3} \lesssim St \lesssim 10^{-2}$. At even larger $St$, the microparticles will quickly sediment in the convection. We also calculate the mean-square displacement (MSD) of the particle's trajectories. At short time intervals, the MSD exhibits a ballistic regime, and it is isotropic in vertical and lateral directions; at longer time intervals, the MSD reflects a confined motion for the particles, and it is anisotropic in different directions. We further obtained a phase diagram of the particle deposition positions on the wall, and we identified three deposition states depending on the particle's density and diameter. An interesting finding is that the dispersed particles preferred to deposit on the vertical wall where the hot plumes arise, which is verified by tilting the cell and altering the rotation direction of the large-scale circulation.

The Pacific Northwest, with its historic abundance of low-cost hydropower and dependence on public power, with experience deregulation and conditioned by this legacy. This analysis focuses on the economic impacts of deregulation on the State of Washington. A 31-sector computable general equilibrium model is used to evaluate the impacts of Washington's economy. In a most likely scenario, electricity exports expand to high-priced regions. The impact on the state economy is a reduction in gross state product as a result of high electricity prices. Returns to capital increase, but returns to private capital and to labor decrease because much of the financial gain accrues to public power.

description: State-space models are important tools for quality control of error-prone animal movement data. The near real-time (within 24 h) capability of the Argos satellite system aids dynamic ocean management of human activities by informing when animals enter intensive use zones. This capability also facilitates use of ocean observations from animal-borne sensors in operational ocean forecasting models. Such near real-time data provision requires rapid, reliable quality control to deal with error-prone Argos locations. We formulate a continuous-time state-space model for the three types of Argos location data (Least-Squares, Kalman filter, and Kalman smoother), accounting for irregular timing of observations. Our model is deliberately simple to ensure speed and reliability for automated, near real-time quality control of Argos data. We validate the model by fitting to Argos data collected from 61 individuals across 7 marine vertebrates and compare model-estimated locations to GPS locations. Estimation accuracy varied among species with median Root Mean Squared Errors usually < 5 km and decreased with increasing data sampling rate and precision of Argos locations. Including a model parameter to inflate Argos error ellipse sizes resulted in more accurate location estimates. In some cases, the model appreciably improved the accuracy of the Argos Kalman smoother locations, which should not be possible if the smoother uses all available information. Our model provides quality-controlled locations from Argos Least-Squares or Kalman filter data with slightly better accuracy than Argos Kalman smoother data that are only available via reprocessing. Simplicity and ease of use make the model suitable both for automated quality control of near real-time Argos data and for manual use by researchers working with historical Argos data.

description: This study investigates the costs of subsidies for land retention and conversion, in addition to a policy that combines the incentives. A Markov model of forest and agricultural land use is estimated for the U.S. South Central region and used to simulate retention and conversion policies. Results suggest a conversion policy is less costly for increasing forest area, and a retention policy is less costly for increasing agricultural land area. The costs of separate subsidies can be up to 300% higher than the costs of combined incentives. However, when administrative costs are taken into account, conversion policies are likely to be less costly.

description: This article introduces a new and general construction of discrete Hodge operator in the context of Discrete Exterior Calculus (DEC). This discrete Hodge operator enables to circumvent the well-centeredness limitation on the mesh with the popular diagonal Hodge. It allows a dual mesh based on any interior point, such as the incenter or the barycenter. It opens the way towards mesh-optimized discrete Hodge operators. In the particular case of a well-centered triangulation, it reduces to the diagonal Hodge if the dual mesh is circumcentric. Based on an analytical development, this discrete Hodge does not make use of Whitney forms, and is exact on piecewise constant forms, whichever interior point is chosen for the construction of the dual mesh. Numerical tests oriented to the resolution of fluid mechanics problems and thermal transfer are carried out. Convergence on various types of mesh is investigated.

description: Using the temperature Green's function approach we investigate entanglement between two non-interacting spin 1 bosons in thermal equilibrium. We show that, contrary to the fermion case, the entanglement is absent in the spin density matrix. Separability is demonstrated using the Peres-Horodecki criterion for massless particles such as photons in black body radiation. For massive particles, we show that the density matrix can be decomposed with separable states.

description: This research study aimed to investigate teachers’ strategies for instructional explanations as a scaffolding approach for supporting conceptual understanding of new knowledge in response to the learning attitudes of community college students in Hong Kong. Adopting an interpretivist research paradigm, a single embedded case study using qualitative methods was implemented. Naturalistic data collected from interviewing the participants, recording actual teaching situations and class observation were coded, analyzed and triangulated. The findings explore the ways college teachers explain new knowledge, reveal the roles of explanations in instructional process and explain the rationales behind the strategies in relation to their perspectives in teaching and about this particular group of students. This study identified various types of instructional explanation strategies and three different explanatory approaches, namely familiarization, visualization and contextualization, which support understanding of different types of declarative, procedural and conceptual knowledge. Instructional explanations are the most prominent scaffolding strategies exercised in content-based lessons. College teachers made use of various tools and strategies to explain new concepts and those explanation strategies were intentionally catered to facilitate students’ understanding. These approaches reflected teachers’ experiences, beliefs and their perspectives on the learning background of Hong Kong students, their attitudes to learning and their perceived needs in the transition years of the college life. Despite this, instructional explanations were still overlooked as a vital and essential strategies even though participants put much of the time in class providing explanations.

description: The percentage of patients hospitalized due to hyponatremia is getting higher. Hyponatremia is the deficiency of sodium electrolyte in the human serum. This deficiency might indulge adverse effects and also associated with longer hospital stay or mortality, if it wasnt actively treated and managed. This work predicts the futuristic sodium levels of patients based on their history of health problems using multilayer perceptron and multivariate linear regression algorithm. This work analyses the patients age, information about other disease such as diabetes, pneumonia, liver-disease, malignancy, pulmonary, sepsis, SIADH, and sodium level of the patient during admission to the hospital. The results of the proposed MLP algorithm is compared with MLR algorithm based results. The MLP prediction results generates 23-72 of higher prediction results than MLR algorithm. Thus, proposed MLR algorithm has produced 57.1 of reduced mean squared error rate than the MLR results on predicting future sodium ranges of patients. Further, proposed MLR algorithm produces 27-50 of higher prediction precision rate.

description: This paper investigates the effects of smoothed bootstrap iterations on coverage probabilities of smoothed bootstrap and bootstrap-t confidence intervals for population quantiles, and establishes the optimal kernel bandwidths at various stages of the smoothing procedures. The conventional smoothed bootstrap and bootstrap-t methods have been known to yield one-sided coverage errors of orders O(n^{-1/2}) and o(n^{-2/3}), respectively, for intervals based on the sample quantile of a random sample of size n. We sharpen the latter result to O(n^{-5/6}) with proper choices of bandwidths at the bootstrapping and Studentization steps. We show further that calibration of the nominal coverage level by means of the iterated bootstrap succeeds in reducing the coverage error of the smoothed bootstrap percentile interval to the order O(n^{-2/3}) and that of the smoothed bootstrap-t interval to O(n^{-58/57}), provided that bandwidths are selected of appropriate orders. Simulation results confirm our asymptotic findings, suggesting that the iterated smoothed bootstrap-t method yields the most accurate coverage. On the other hand, the iterated smoothed bootstrap percentile method interval has the advantage of being shorter and more stable than the bootstrap-t intervals.

description: Surface enhanced Raman spectroscopy (SERS) is a precise and non-invasive analytical technique that is widely used in chemical analysis, environmental protection, food processing, pharmaceutics, and diagnostic biology. However, it is still a challenge to produce highly sensitive and reusable SERS substrates with minimum fluorescence background. In this work, we propose the use of van der Waals heterostructures of two-dimensional materials (2D materials) to cover plasmonic metal nanoparticles to solve this challenge. The heterostructures of atomically thin boron nitride (BN) and graphene provide synergistic effects: (1) electrons could tunnel through the atomically thin BN, allowing the charge transfer between graphene and probe molecules to suppress fluorescence background; (2) the SERS sensitivity is enhanced by graphene via chemical enhancement mechanism (CM) in addition to electromagnetic field mechanism (EM); (3) the atomically thin BN protects the underlying graphene and Ag nanoparticles from oxidation during heating for regeneration at 360 °C in the air so that the SERS substrates could be reused. These advances will facilitate wider applications of SERS, especially on the detection of fluorescent molecules with higher sensitivity.

description: The chaotic hypothesis has several implications which have generated interest in the literature because of their generality and because a few exact predictions are among them. However its application to Physics problems requires attention and can lead to apparent inconsistencies. In particular there are several cases that have been considered in the literature in which singularities are built in the models: for instance when among the forces there are Lennard-Jones potentials (which are infinite in the origin) and the constraints imposed on the system do not forbid arbitrarily close approach to the singularity even though the average kinetic energy is bounded. The situation is well understood in certain special cases in which the system is subject to Gaussian noise; here the treatment of rather general singular systems is considered and the predictions of the chaotic hypothesis for such situations are derived. The main conclusion is that the chaotic hypothesis is perfectly adequate to describe the singular physical systems we consider, i.e. deterministic systems with thermostat forces acting according to Gauss' principle for the constraint of constant total kinetic energy (``isokinetic Gaussian thermostats''), close and far from equilibrium. Near equilibrium it even predicts a fluctuation relation which, in deterministic cases with more general thermostat forces (i.e. not necessarily of Gaussian isokinetic nature), extends recent relations obtained in situations in which the thermostatting forces satisfy Gauss' principle. This relation agrees, where expected, with the fluctuation theorem for perfectly chaotic systems. The results are compared with some recent works in the literature.

description: A methodological approach to obtain bounds on the value of information based on an inexact representation of the decision maker's utility function is presented. Stochastic dominance procedures are used to derive the bounds. These bounds provide more information than the single point estimates associated with traditional decision analysis approach to valuing information, in that classes of utility functions can be considered instead of one specific utility function. Empirical results for valuing seasonal climate forecasts illustrate that the type of management strategy given by the decision maker's prior knowledge interacts with the decision maker's risk preferences to determine the bounds.

description: The thermal freeze-out mechanism for relic dark matter heavier than $O(10-100 $ TeV$)$ requires cross-sections that violate perturbative unitarity. Yet the existence of dark matter heavier than these scales is certainly plausible from a particle physics perspective, pointing to the need for a non-thermal cosmological history for such theories. Topological dark matter is a well-motivated scenario of this kind. Here the hidden-sector dark matter can be produced in abundance through the Kibble-Zurek mechanism describing the non-equilibrium dynamics of defects produced in a second order phase transition. We revisit the original topological dark matter scenario, focusing on hidden-sector magnetic monopoles, and consider more general cosmological histories. We find that a monopole mass of order ($1-10^5$) PeV is generic for the thermal histories considered here, if monopoles are to entirely reproduce the current abundance of dark matter. In particular, in a scenario involving an early era of matter domination, the monopole number density is always less than or equal to that in a pure radiation dominated equivalent provided a certain condition on critical exponents is satisfied. This results in a larger monopole mass needed to account for a fixed relic abundance in such cosmologies.
