description: The influence of topological defects on phase synchronization and phase coherence in two-dimensional arrays of locally-coupled, nonidentical, chaotic oscillators is investigated. The motion of topological defects leads to a breakdown of phase synchronization in the vicinities of the defects; however, the system is much more phase coherent as long as the coupling between the oscillators is strong enough to prohibit the continuous dynamical creation and annihilation of defects. The generic occurrence of topological defects in two and higher dimensions implies that the concept of phase synchronization has to be modified for these systems.

description: We develop a graphical representation of polynomial invariants of unitary gauge groups, and use it to find the algebraic curve corresponding to a hyperkahler quotient of a linear space. We apply this method to four dimensional ALE spaces, and for the A_k, D_k, and E_6 cases, derive the explicit relation between the deformations of the curves away from the orbifold limit and the Fayet-Iliopoulos parameters in the corresponding quotient construction. We work out the orbifold limit of E_7, E_8, and some higher dimensional examples.

description: We present the Transiting Exoplanet Survey Satellite (TESS) Habitable Zone Stars Catalog, a list of 1822 nearby stars with a TESS magnitude brighter than T = 12 and reliable distances from Gaia DR2, around which the NASA's TESS mission can detect transiting planets, which receive Earth-like irradiation. For all those stars TESS is sensitive down to 2 Earth radii transiting planets during one transit. For 408 stars TESS can detect such planets down to 1 Earth size during one transit. For 1690 stars, TESS has the sensitivity to detect planets down to 1.6 times Earth-size, a commonly used limit for rocky planets in the literature, receiving Earth-analog irradiation. We select stars from the TESS Candidate Target List, based on TESS Input Catalog Version 7. We update their distances using Gaia Data Release 2, and determine whether the stars will be observed for long enough during the 2 year prime mission to probe their Earth equivalent orbital distance for transiting planets. We discuss the subset of 227 stars for which TESS can probe the full extent of the Habitable Zone, the full region around a star out to about a Mars-equivalent orbit. Observing the TESS Habitable Zone Catalog Stars will also give us deeper insight into the occurrence rate of planets, out to Earth-analog irradiation as well as in the Habitable Zone, especially around cool stars. We present the stars by decreasing angular separation of the 1AU equivalent distance to provide insights into which stars to prioritize for ground-based follow-up observations with upcoming extremely large telescopes.

description: How can we better provide long-term resiliency and biodiversity for urban ecosystems? One potential solution is understanding and using local cryptogamic ecosystems as a model for the transference of adaptive species to urban surfaces. To find adaptive plant species, an assessment of bryophyte community (mosses) databases were advanced through field collections of local species and observed for 14 month in North East Ohio USA from May 2018 to April 2019. eighteen local moss species were mapped, collected, identified andtested for transplantation. And it was found that several species appear to be adaptable, or already inhabiting, urban settings. Provided here palettes of plants categorized by growth habits and functional traits, and ecosystem services provided by the plants within an urban use typology. Lastly, the importance of an innovative surface environment and growing materiality is discussed through visual modeling and mock up substrate examples. With these findings, a better understanding of the transferability of native cryptogams can assist in the facilitation of biodiversity and creation of ecological services in urban areas.
Contaminant transport in water-filled mine-pits

Publisher: name: The University of British Columbia
Year: 2009

description: Water-filled decommissioned mine-pits are likely to contain deleterious concentrations of various dissolved metals and salts. It is apparent that any given property of interest is not evenly distributed throughout the water column; the pit-lake is stratified. Thermal and chemical stratification are the controlling factors influencing the density of water and it is density that controls the overall stratification as heavy fluid cannot sit on top of light fluid. It is important to determine how concentrations of these properties might change over time. This paper describes some unique field data collected in the Brenda Mines pit-lake near Peachland, BC. The data illustrates the dynamics that should be expected before and after ice-on. Modelling based on this data indicates the sensitivity of the system to wind at the time of fall over-turn. The generality of the modelling is discussed, along with required input information.
An aperiodic tile with edge-to-edge orientational matching rules

description: We present a single, connected tile which can tile the plane but only non-periodically. The tile is hexagonal with edge markings, which impose simple rules as to how adjacent tiles are allowed to meet across edges. The first of these rules is a standard matching rule, that certain decorations match across edges. The second condition is a new type of matching rule, which allows tiles to meet only when certain decorations in a particular orientation are given the opposite charge. This forces the tiles to form a hierarchy of triangles, following a central idea of the Socolar--Taylor tilings. However, the new edge-to-edge orientational matching rule forces this structure in a very different way, which allows for a surprisingly simple proof of aperiodicity. We show that the hull of all tilings satisfying our rules is uniquely ergodic and that almost all tilings in the hull belong to a minimal core of tilings generated by substitution. Identifying tilings which are charge-flips of each other, these tilings are shown to have pure point dynamical spectrum and a regular model set structure.

Fundamental thermodynamical equation of a self-gravitating system

description: The features of the fundamental thermodynamical relation (expressing entropy as function of state variables) that arise from the self-gravitating character of a system are analyzed. The models studied include not only a spherically symmetric hot matter shell with constant particle number but also a black hole characterized by a general thermal equation of state. These examples illustrate the formal structure of thermodynamics developed by Callen as applied to a gravitational configuration as well as the phenomenological manner in which Einstein equations largely determine the thermodynamical equations of state. We consider in detail the thermodynamics and quasi-static collapse of a self-gravitating shell. This includes a discussion of intrinsic stability for a one-parameter family of thermal equations of state and the interpretation of the Bekenstein bound. The entropy growth associated with a collapsing sequence of equilibrium states of a shell is computed under different boundary conditions in the quasi-static approximation and compared with black hole entropy. Although explicit expressions involve empirical coefficients, these are constrained by physical conditions of thermodynamical origin. The absence of a Gibbs-Duhem relation and the associated scaling laws for self-gravitating matter systems are presented.

Influences on Orchestra Teachers' Pedagogical Choices: a Multiple-case Study

Influence (Literary, artistic, etc.)

description: This study explored orchestra educators’ perceptions of influences on pedagogy. Many professional orchestras of the twentieth and early twenty-first centuries maintained a centralized, hierarchical structure in rehearsal and performance. An emphasis on preparing primary and secondary grade school students for real world experiences have prompted many orchestra educators to emulate the traditional authoritarian structure of professional orchestras. The emergence of student-centered pedagogy and democratization of music education in the twentieth century has prompted some orchestra educators in schools to employ progressive teaching approaches. Despite research addressing orchestral best practices in classrooms and pedagogical orientation, there is insufficient research regarding how orchestra educators’ perceived influences on pedagogy and pedagogical rationale encourage or discourage teacher- and/or student-centered teaching methods. This study did not compare the efficacy of teacher- and student-centered orchestra pedagogy, but examined orchestra educators’ perception of pedagogical influences, rationale/justification of pedagogical choice, and influences on the implementation of teacher- and/or student-centered instruction. A demographic inventory survey was sent to 422 orchestra educators in a northeastern region of the United States. Twenty-one factors were cited as having an influence on orchestra classroom pedagogy by thirteen orchestra educator survey respondents. Of the thirteen survey respondents, five orchestra educators participated in this multiple-case study. A close examination of five orchestra educators found time, orchestra content, personal philosophy, rapport with students/colleagues, and pedagogical knowledge as having shaped teacher- and student-centered pedagogical decisions. The majority of research participants did not view themselves as teacher- or student-centered, but found various needs to implement both approaches. A cross-examination of pedagogical choice and rationale triggered a discussion on the status of orchestra, contextual influences, educators’ sense of self/happiness, what student-centered orchestras looks like, and pedagogical freedom. How educators view and negotiate these facets of education might dictate the lengths to which they can implement their preferred pedagogical approach.

description: The spontaneous emission rate Γof a two-level atom inside a chaotic cavity fluctuates strongly from one point to another because of fluctuations in the local density of modes. For a cavity with perfectly conducting walls and an opening containing N wavechannels, the distribution of Γis given by P(Γ) \propto Γ^{N/2-1}(Γ+Γ_0)^{-N-1}, where Γ_0 is the free-space rate. For small N the most probable value of Γis much smaller than the mean value Γ_0.

description: Strong vortex pinning in FeSe could be useful for technological applications and could provide clues about the coexistence of superconductivity and nematicity. To characterize the pinning of individual, isolated vortices, we simultaneously apply a local magnetic field and image the vortex motion with scanning SQUID susceptibility. We find that the pinning is highly anisotropic: the vortices move easily along directions that are parallel to the orientations of twin domain walls and pin strongly in a perpendicular direction. These results are consistent with a scenario in which the anisotropy arises from vortex pinning on domain walls and quantify the dynamics of individual vortex pinning in FeSe.

description: Experiments on 2+1-dimensional piles of elongated particles are performed. Comparison with previous experiments in 1+1 dimensions shows that the addition of one extra dimension to the dynamics changes completely the avalanche properties, appearing a characteristic avalanche size. Nevertheless, the time single grains need to cross the whole pile varies smoothly between several orders of magnitude, from a few seconds to more than 100 hours. This behavior is described by a power-law distribution, signaling the existence of scale invariance in the transport process.

Complex dynamics in a simple model of pulsations for Super-Asymptotic Giant Branch Stars

description: When intermediate mass stars reach their last stages of evolution they show pronounced oscillations. This phenomenon happens when these stars reach the so-called Asymptotic Giant Branch (AGB), which is a region of the Hertzsprung-Russell diagram located at about the same region of effective temperatures but at larger luminosities than those of regular giant stars. The period of these oscillations depends on the mass of the star. There is growing evidence that these oscillations are highly correlated with mass loss and that, as the mass loss increases, the pulsations become more chaotic. In this paper we study a simple oscillator which accounts for the observed properties of this kind of stars. This oscillator was first proposed and studied by Icke et al. [Astron.Astrophys. 258, 341 (1992)] and we extend their study to the region of more massive and luminous stars - the region of Super-AGB stars. The oscillator consists of a periodic nonlinear perturbation of a linear Hamiltonian system. The formalism of dynamical systems theory has been used to explore the associated Poincare map for the range of parameters typical of those stars. We have studied and characterized the dynamical behaviour of the oscillator as the parameters of the model are varied, leading us to explore a sequence of local and global bifurcations. Among these, a tripling bifurcation is remarkable, which allows us to show that the Poincare map is a nontwist area preserving map. Meandering curves, hierarchical-islands traps and sticky orbits also show up. We discuss the implications of the stickiness phenomenon in the evolution and stability of the Super-AGB stars.

Lasing Threshold and Mode Competition in Chaotic Cavities

description: The lasing threshold is studied of a multi-mode chaotic cavity (linear size D >> wavelength λ) coupled to the outside through a small hole (linear size d << λ). For sufficiently weak absorption by the boundaries, the statistical distribution of the threshold is wide, its mean value being much less than the pumping rate needed to compensate the average loss. The average number N_{nc} >> 1 of non-competing excited modes is proportional to the square root of the pumping rate. We use the classical model of spatial hole burning to account for mode competition and find a reduction in the average number of excited modes to N =3^{1/3} N_{nc}^{2/3}.

description: The fields of machine learning and causal inference have developed many concepts, tools, and theory that are potentially useful for each other. Through exploring the possibility of extracting causal interpretations from black-box machine-trained models, we briefly review the languages and concepts in causal inference that may be interesting to machine learning researchers. We start with the curious observation that Friedman’s partial dependence plot has exactly the same formula as Pearl’s back-door adjustment and discuss three requirements to make causal interpretations: a model with good predictive performance, some domain knowledge in the form of a causal diagram and suitable visualization tools. We provide several illustrative examples and find some interesting and potentially causal relations using visualization tools for black-box models.

description: Vocal communicators such as humans and songbirds rely on their auditory systems to learn, recognize, and encode acoustic features of communication vocalizations. Yet it remains unclear how varying behavioral, experimental, and developmental contexts impact neural coding in the songbird auditory system. In this dissertation I demonstrate that experimental and behavioral contexts relating to arousal are sufficient to alter neural excitability in a way that has implications for neural coding in the songbird auditory system.  First I show that urethane, a common anesthetic used in neurophysiological studies of songbird and mammalian auditory neurons, suppresses neural excitability but does not alter spectrotemporal tuning or neural discrimination in single auditory midbrain neurons.  Next, I demonstrate that neurons in the songbird primary auditory cortical region Field L are sensitive to local concentrations of norepinephrine, a neurotransmitter involved mediating changes in arousal and behavioral state. Lastly, I report the results of a developmental study that demonstrates experience-dependent changes in temporal and spectral tuning in songbird auditory cortical neurons during vocal learning.  These developmental effects were found to have region and cell-type specificity, and highlight potential functional roles for dorsal and ventral auditory cortical neurons in the songbird auditory cortex.  The findings reported here have important implications for future studies into the neurophysiology of vocal learning.

description: Objective: The purpose of this study is to provide an overview of the prevalence of driving under the influence of alcohol (DUI) according to day of the week, specific roads (urban/rural), daytime or nighttime, and vehicle category. In addition, this study examines how the prohibition of selling alcoholic drinks in shops and supermarkets (not in restaurants) after 10 p.m. has affected the prevalence of DUI. Method: Breath alcohol concentration (BrAC) was collected from all drivers through police checkpoints at 54 locations in Serbia. In this study, 17,945 drivers were tested in urban areas and 19,507 in rural areas. The relationship between DUI during the prohibition on alcohol sales in Belgrade and other large cities in Serbia was determined using logistic regression. Results: On average, every 100th driver in traffic in Serbia was DUI (0.99%). This study shows that the 0 blood alcohol concentration (BAC) limit for motorcyclists does not have an influence on DUI. Moreover, motorcyclists represent the category with the highest share of DUI, with a statistically significantly larger difference compared to drivers of other vehicle categories. These results may be a consequence of the fact that a large number of drivers drive both motorcycles and other vehicle categories (cars or mopeds), so the different BAC limits for nonprofessional drivers may create confusion about the legal BAC limit. Conclusions: This study suggests that the required legal BAC limit for nonprofessional drivers should be the same. The prohibition of selling alcoholic drinks in Belgrade after 10 p.m. does not decrease the prevalence of DUI.

description: In this paper, we study the iteration complexity of cubic regularization of Newton method for solving composite minimization problems with uniformly convex objective. We introduce the notion of second-order condition number of a certain degree and justify the linear rate of convergence in a nondegenerate case for the method with an adaptive estimate of the regularization parameter. The algorithm automatically achieves the best possible global complexity bound among different problem classes of uniformly convex objective functions with Hölder continuous Hessian of the smooth part of the objective. As a byproduct of our developments, we justify an intuitively plausible result that the global iteration complexity of the Newton method is always better than that of the gradient method on the class of strongly convex functions with uniformly bounded second derivative.

This is a generalisation of the Kuchař idea of finding alternative constraints for canonical gravity. The new scalars may be used in place of the hamiltonian constraint of general relativity and, together with the usual momentum constraints, replace the Dirac algebra for pure gravity with a true Lie algebra: the semidirect product of the Abelian algebra of the new constraint combinations with the algebra of spatial diffeomorphisms.

description: Built around the SMARDDA modules for magnetic field-line tracing [IEEE Tr. Plasma Sc. 42 (2014) 1932], the SMITER code package (SMARDDA for ITER) is a new graphical user interface (GUI) framework for power deposition mapping on tokamak plasma-facing components (PFC) in the full 3-D CAD geometry of the machine, taking as input a user-defined specification for parallel heat flux in the scrape-off layer (SOL) and a description of the equilibrium magnetic flux. The software package provides CAD model import and integration with the ITER Integrated Modelling and Analysis Suite (IMAS), parametric CAD components catalogue and modelling, CAD de-featuring for PFC surface extraction, meshing, visualization (using an integrated ParaView module), Python scripting and batch processing, storage in hierarchical data files, with several simulation cases in one study running in parallel and using message passing interface (MPI) for code speed-up. An integrated ParaView module can combine CAD geometry, magnetic field equilibrium, meshes and results for detailed setup analysis and a module is under development for full finite element computation of surface temperatures resulting from the power deposition patterns on 3-D PFCs. The code package has been developed for ITER, but can be deployed for similar modelling of any tokamak. This paper presents and discusses key features of this field-line tracing environment, demonstrates benchmarking against existing field-line tracing code and provides specific examples of power deposition mapping in ITER for different plasma configurations.

description: Application Service Providers (ASPs) obtaining resources from multiple clouds have to contend with different management and control platforms employed by the cloud service providers (CSPs) and network service providers (NSP). Distributing applications on multiple clouds has a number of benefits but the absence of a common multi-cloud management platform that would allow ASPs dynamic and real-time control over resources across multiple clouds and interconnecting networks makes this task arduous. OpenADN, being developed at Washington University in Saint Louis, fills this gap. However, performance issues of such a complex, distributed and multi-threaded platform, not tackled appropriately, may neutralize some of the gains accruable to the ASPs. In this paper, we establish the need for and methods of collecting precise and fine-grained behavioral data of OpenADN like platforms that can be used to optimize their behavior in order to control operational cost, performance (e.g., latency) and energy consumption.

We define the notion of an asymptotic Co(X)-morphism from A to B and construct representable E-theory groups RE(X;A,B). These are the universal groups on the category of separable Co(X)-algebras that are Co(X)-stable, Co(X)-homotopy-invariant, and half-exact. If A is RKK(X)-nuclear, these groups are naturally isomorphic to Kasparov's representable KK-theory groups RKK(X;A,B). Applications and examples are also discussed.

description: Cardiovascular disease remains the leading cause of death worldwide. A lack of curative treatments and a shortage of transplant hearts necessitate new approaches to cardiac repair. Recent advances, including the advent of pluripotent stem cell-derived cardiomyocytes and the development of tissue engineering techniques, represent promising new directions to remuscularize the heart or induce endogenous regeneration. However, these approaches are currently limited by the immaturity of differentiated cardiomyocytes and the inability of cardiomyocytes to functionally integrate with the damaged myocardium. Mimicking the cardiomyocyte niche, the myriad signals surrounding the cardiomyocyte, may enhance the utility of these cells. In this dissertation, each of the three aspects of the cardiomyocyte niche: physical signals, the extracellular matrix, and soluble factors, are examined for their ability to guide cardiomyocyte growth and function. We first explore the effect of electrical stimulation, a physical signal pervasive in the heart, on pluripotent stem cell-derived cardiomyocyte development and function. Stimulated cardiomyocytes are more mature, show greater cell-cell connectivity, and are more resistant to tachycardic stress. Cardiomyocytes adapt their beating rate to the stimulation frequency, an effect mediated by the emergence of a rapidly depolarizing cell type and ion channel expression. We next engineer cardiovascular tissue architecture, critical components of the extracellular matrix, using a micromolding approach and determine geometric parameters necessary for the induction of cardiomyocyte alignment and tissue synchrony. We finally test pluripotent stem cell-derived cardiomyocyte exosomes, soluble nanovesicles specifically packaged and secreted by the cell, in vitro and in vivo, demonstrating functional improvement and reduction of arrhythmia in the heart. Therefore, the use of the cardiomyocyte niche supports the interrogation of cellular function to enable new cell-based approaches for the reduction of arrhythmia or induction of repair in the heart.

description: We are concerned with the global weak continuity of the Cartan structural system -- or equivalently, the Gauss--Codazzi--Ricci system -- on semi-Riemannian manifolds with lower regularity. For this purpose, we first formulate and prove a geometric compensated compactness theorem on vector bundles over semi-Riemannian manifolds with lower regularity (Theorem 3.2), extending the classical quadratic theorem of compensated compactness. We then deduce the $L^p$ weak continuity of the Cartan structural system for $p>2$: For a family $\{\mathcal{W}_\varepsilon\}$ of connection $1$-forms on a semi-Riemannian manifold $(M,g)$, if $\{\mathcal{W}_\varepsilon\}$ is uniformly bounded in $L^p$ and satisfies the Cartan structural system, then any weak $L^p$ limit of $\{\mathcal{W}_\varepsilon\}$ is also a solution of the Cartan structural system. Moreover, it is proved that isometric immersions of semi-Riemannian manifolds into semi-Euclidean spaces can be constructed from the weak solutions of the Cartan structural system or the Gauss--Codazzi--Ricci system (Theorem 5.1), which leads to the $L^p$ weak continuity of the Gauss--Codazzi--Ricci system on semi-Riemannian manifolds. As further applications, the weak continuity of Einstein's constraint equations, general immersed hypersurfaces, and the quasilinear wave equations is also established.

Background

The pediatric relative fat mass (RFM) has been recently presented and validated as an index for estimating percentage body fat (%BF) in North American children and adolescents. Similar to body mass index (BMI) and tri-ponderal mass index (TMI), RFM uses anthropometric measures (i.e., weight, height and waist circumference) to estimate body composition. The primary purpose of this study was to validate the newly developed RFM equation for %BF prediction in Southern Brazilian adolescents; as secondary objective, we compared %BF estimation from BMI- and TMI-derived equations.

Methods

A total of 631 individuals (434 boys) aged 11 to 18 were analyzed. Bland–Altman analyses were used to determine concordance between predicted equations and %BF measured by DXA; results are presented using mean difference (i.e., bias) and standard deviation. Sensitivity and specificity were calculated for %BF percentile classifications.

Results

RFM underestimated %BF in 65.2% of boys (− 4.3 ± 2.8%) and 84.8% of girls (− 5.3 ± 2.7%). In contrast, TMI overestimated %BF in 62.9% of boys (4.0 ± 2.9%) and 56.3% (3.5 ± 3.0%) of girls. The performance of BMI showed mixed results; %BF was overestimated in 68.4% of boys (5.0 ± 4.0%) and underestimated in 67.5% of girls (− 3.9 ± 2.6%), all p < 0.001. Although, RFM had the highest specificity for %BF percentile classifications, sensitivity was low and inferior to BMI and TMI.

Conclusion

TMI was superior to RFM and BMI in predicting %BF in Southern Brazilian adolescents. Using RFM, BMI or TMI equations for %BF prediction without a population-specific correction factor may lead to incorrect interpretations. We suggest that correction factors should be investigated to improve the accuracy of these surrogate indices for body composition assessment.

description: Despite the abundant literature on financial development and economic growth nexus, the debate is far from settled. In this paper we create a financial development index using principal component analysis (PCA) and use it to examine the effect of financial intermediation on economic growth within the East African Community (EAC) using panel data over the period 1985-2017. The DOLS and FMOLS models are estimated since they control for heterogeneity, serial correlation, small sample bias and endogeneity in the presence of long run relationship. The results indicate that financial intermediation has a positive and significant effect on economic performance of the EAC countries in the long run. Among the controls, capital formation and FDI also have positive effects on growth while the growth of the population reduces the per capita income.

description: This dissertation explores the rise of transnational state torture and the efforts of the Left to resist and denounce it in South America in the 1970s. Looking principally to Brazil and Argentina, I ask how torture was understood by the officials who employed it and the revolutionaries who resisted and denounced it at a time when such calibrated violence stood at the heart of political struggle. While torture’s status as a grave violation of human rights is often taken for granted today, I show that in 1970s-era southern South America, many perpetrators and victims alike instead regarded torture as a powerful counterrevolutionary weapon, one capable of generating the raw data on which the region’s sophisticated information-management systems relied. At the same time, both revolutionaries and regime agents recognized such systematic torture as a grave liability for its practitioners. Militants and their allies abroad capitalized on this liability by disseminating testimonies that drew the world’s attention to South American torture chambers. Their efforts helped to consolidate the politics of bodily integrity at the heart of the current global human rights regime, yet they were unable to curb state violence or advance socialism. Drawing on dozens of archival collections from ten countries, I reconstruct the now-forgotten meanings of torture that defined this formative juncture, demonstrating the potential of history to reinvigorate a policy debate centered for too long on the question, “Does torture work?” Instead, I ask readers to consider the work that torture and its denunciation have performed at a critical moment in the past, in order to generate new strategies to counteract it today.

description: We investigate chaotic scattering on an attractive step potential with a quadrupolar deformation. The phase space features of the bound billiard are studied by using the notion of symmetry lines to find periodic orbits. We show that the scattering dynamics is intimately linked to structures in the bound billiard (infinite potential wall) phase space. The existence of preferred scattering directions is shown to be a consequence of large scale features of the phase space such as the period-two orbits. Self-similarity in the scattering functions is directly linked to unstable periodic orbits of the bound phase space. The main observations and methodology are applicable to concave billiards in general.

Publisher: name: Columbia University
Year: 2015
Subjects: Computer science

description: As cloud technology matures and trendsetters like Google, Amazon, Microsoft, Apple, and VMware have become the top-tier cloud services players, public cloud services have turned mainstream for individual users.  In this work, I propose a set of techniques that can be used as the basis for alleviating cloud customers' privacy concerns and elevating their condence in using the cloud for security-sensitive operations as well as trusting it with their sensitive data. The main goal is to provide cloud customers' with a reliable mechanism that will cover the entire path of tracking their sensitive data, while they are collected and used by cloud-hosted services, to the presentation of the tracking results to the respective data owners. In particular, my design accomplishes this goal by retrofitting legacy applications with data flow tracking techniques and providing the cloud customers with comprehensive information flow auditing capabilities. For this purpose, we created CloudFence, a cloud-wide fine-grained data flow tracking (DFT) framework, that sensitive data in well-defined domains, offering additional protection against inadvertent leaks and unauthorized access.
