Enlargeability, foliations, and positive scalar curvature
(Springer Verlag, 201703)We extend the deep and important results of Lichnerowicz, Connes, and GromovLawson which relate geometry and characteristic numbers to the existence and nonexistence of metrics of positive scalar curvature (PSC). In ... 
Axiomatizing changing conceptions of the geometric continuum I: EuclidHilbert
(Oxford University Press, 20171120)We begin with a general account of the goals of axiomatization, introducing a variant (modest) on Detlefsen’s notion of ‘complete descriptive axiomatization’. We examine the distinctions between the Greek and modern view ... 
Coordination Event Detection and Initiator Identification in Time Series Data
(Association for Computing Machinery, 201807)Behavior initiation is a form of leadership and is an important aspect of social organization that affects the processes of group formation, dynamics, and decisionmaking in human societies and other social animal species. ... 
Encoding DNA sequences by integer chaos game representation
(Mary Ann Liebert, 20171219)Motivation: DNA sequences are fundamental for encoding genetic information. The genetic information may be understood not only by symbolic sequences but also from the hidden signals inside the sequences. The symbolic ... 
Periodic Corrugations to Increase Efficiency of Thermophotovoltaic Emitting Structures
(AIP Publishing, 20190206)In this letter, we consider the question of designing insulator/metal thermovoltaic structures with periodically corrugated interfaces that give optimal performance based on the metric of useful power density. Using a Monte ... 
MOST BOSON QUANTUM STATES ARE ALMOST MAXIMALLY ENTANGLED
(American Mathematical Society, 20180904)The geometric measure E of entanglement of an m qubit quantum state takes maximal possible value m. In previous work of Gross, Flammia, and Eisert, it was shown that E ≥ m − O(log m) with high probability as m → ∞. They ... 
ON THE COMPARISON OF STABLE AND UNSTABLE pCOMPLETION
(American Mathematical Society, 201902)In this note we show that a pcomplete nilpotent space X has a pcomplete suspension spectrum if and only if its homotopy groups pi X* are bounded ptorsion. In contrast, if pi X* is not all bounded ptorsion, we locate ... 
Modeling Temporal and Structural Information in Time Series Data
(20180830)Time series data is a sequence of data with temporal information at each position in the sequence. Such data widely exists in various disciplines. In computer science, different areas such as computational biology, signal ... 
Realizing Provider Policies on Cellular Networks
(20181120)Background applications (e.g., cloudsync, software and firmware updates), which previously relied on wired or WiFi networks, are starting to rely on cellular networks to transfer vast amounts of data. While wired and ... 
A Study on the Use of MobileSpecifc HTML5 WebAPI Calls on the Web
(20181119)The growth of smartphones diffusion in the last decade and the pervasiveness of the web in the current lifestyle pose the attention on the privacy and security of the users. While it is well known how browserrelated data ... 
Adversarial Structural Learning: Approximating Training Data for MultiVariate Predictions
(20181119)In this thesis, we address two important characteristics of prediction tasks in many real world problems by developing an adversarial classification framework. Structured data is the feature of many real world applications ... 
A Distributed Graph Approach For Retrieving Linked RDF Data Using Supercomputing Systems
(20181109)Many RDF data systems are able to perform queries on different types of connected data structures for a scalable range of input. Partitioning techniques, graph algorithms, and mem ory based indexing schemes have been ... 
Automatic Exploit Generation for Web Applications
(20181102)Web applications are valuable targets for security attacks because of their popularity and the sensitive data that they handle (e.g., credit card data, medical records, and personal information). Vulnerabilities that ... 
Symbolic and Neural Approaches for Learning Other Agents’ Intentional Models using Interactive POMDPs
(20181127)Interactive partially observable Markov decision processes (IPOMDPs) provide a principled framework for planning and acting in a partially observable, stochastic and multiagent environment. IPOMDPs augment POMDP beliefs ... 
Inference of Leadership of Coordinated Activity in Time Series
(20181017)When a group of people decides to move somewhere together, who is the initiator who starts moving and everyone follows? Do the group members follow friends around them or do they prefer to follow specific individuals? These ... 
Upper Bounds on the Density of Two Radius Packings of Disks in the Plane
(20180910)A new upper density bound on tworadius packings of disks in the plane is presented at a homogeneity which does not admit compact packings. 
WOJ: Enabling WriteOnce Fulldata Journaling in SSDs by Using WeakHashingbased Deduplication
(Elsevier, 201811)Journaling is a commonly used technique in file systems to provide data reliability for applications. Fulldata journaling, which stores all file system (data and metadata) updates in a journal before they are applied to ... 
The Frobenius Complexity of Hibi Rings
(20180816)We study the Frobenius complexity of Hibi rings over fields of characteristic p. In particular, for a certain class of Hibi rings (which we call anticanonical level), we compute the limit of the Frobenius complexity as p ... 
Parametric and Nonparametric Approaches for Estimating RiskNeutral Density
(20180605)In this dissertation, we propose one parametric method and one nonparametric method for estimating the riskneutral density, which is a fundamental concept in pricing financial derivatives, risk management, and assessing ... 
Extremal Problems on Directed Hypergraphs and the ErdösGyárfás Ramsey Problem Variant for Graphs
(20180530)Let a 2 to 1 directed hypergraph be a 3uniform hypergraph where every edge has two tail vertices and one head vertex. For any such directed hypergraph F let the nth extremal number of F be the maximum number of edges that ...
