Computing Agreement in a Mixed System

Sakshi Bhatia
This dissertation develops a comprehensive response to the question of how agreement is computed in Hindi-Urdu – a language with a mixed agreement system where the verb can agree with a subject or an object depending on the structural context. This dissertation covers new empirical and theoretical ground in two domains. First, I identify three kinds of atypical agreement patterns which are not accounted for under traditional approaches Hindi-Urdu agreement -- verb agreement with the...

Ecology of the Elusive: Genome-Informed Investigation of Soil Microbial Diversity

Lauren Alteio
Soil is considered one of the most diverse ecosystems on Earth, harboring diversity of organisms across the three domains of life. It is spatially and chemically heterogeneous: properties that intertwine in a complex matrix to support organismal diversity and function across different scales. Soil microorganisms both respond to and drive changes in ecosystems through metabolic activities. A single gram of soil is teeming with millions of cells comprised of thousands of species. Much of this...

IMPROVING THE SHEAR BEHAVIOR OF CROSS LAMINATED TIMBER (CLT) PANELS BY OPTIMIZATION OF LAMINATES PLY-ORIENTATION USING EASTERN HEMLOCK

Alireza Bahmanzad
Cross-laminated timber (CLT), is a new generation of engineered wood product initially established in Europe, is utilized in residential and non-residential applications in several countries. CLT is new to the north of the United States, but Europeans have used CLT more than 25 years as an eco-friendly construction product in many construction sectors. Also many spectacular low, mid and even high-rise building constructed around the world using CLT products. CLT panels can be used in...

Citizenship in transit: perils and promises of crossing Mexico

Martha Balaguera
What kind of politics emerges under dire conditions of violence and precarity in the context of transit migration across Mexico? How is sanctuary practiced and gendered? This dissertation analyzes a range of experiences of transit and sanctuary practices of hospitality, care and solidarity, particularly those of marginalized women, nonbinary individuals, and grassroots movements that reveal an emerging pattern of transnational citizenship from below. As a defining issue of the 21stcentury, international migrations have provided an...

Bruhat-Tits Buildings and a Characteristic p Unimodular Symbol Algorithm

Matthew Bates
Let k be the finite field with q elements, let F be the field of Laurent series in the variable 1/t with coefficients in k, and let A be the polynomial ring in the variable t with coefficients in k. Let SLn(F) be the ring of nxn-matrices with entries in F, and determinant 1. Given a polynomial g in A, let Gamma(g) subset SLn(F) be the full congruence subgroup of level g. In this thesis...

Cultural Heritage and Climate Change: Exploring the Impacts and Issues

Elizabeth Brabec, Andrew Potts & Julianne Polanco
As noted at the 2017 ICOMOS Assembly in Delhi, cultural heritage is both under threat from climate change, and an asset in our attempts to adapt to and mitigate its impacts. The Paris Agreement emphasizes the need for urgency about climate change; cultural heritage can play a central role in this effort. For example, iconic sites at risk from storms, coastal erosion, wildfires or permafrost thaw can alert public to the very real impacts and...

Thermodynamics of Polyelectrolyte Solutions and Polymer Crystallization

Sabin Adhikari
Polymeric systems exhibit interesting macroscopic properties under different thermodynamic conditions and are prevalent in both biology and synthetic world. How a system of polymers behaves under different thermodynamic conditions is determined by the interplay of different possible interactions such as short-ranged Van der Waals and long-ranged electrostatic interactions and the entropy of individual components present in the system. This work is mostly focused on the theoretical study of the thermodynamic phase behaviors of charged polymers...

Engineered Nanoparticles for Site-Specific Bioorthogonal Catalysis: Imaging and Therapy

Riddha Das
Bioorthogonal catalysis offers a strategy for chemical transformations complementary to bioprocesses and has proven to be a powerful tool in biochemistry and medical sciences. Transition metal catalysts (TMCs) have emerged as a powerful tool to execute selective chemical transformations, however, lack of biocompatibility and stability limits their use in biological applications. Incorporation of TMCs into nanoparticle monolayers provides a versatile strategy for the generation of bioorthogonal nanocatalysts known as “nanozymes”. We have fabricated a family...

An Empirical Assessment of the Effectiveness of Deception for Cyber Defense

Kimberly Ferguson-Walter
The threat of cyber attacks is a growing concern across the world, leading to an increasing need for sophisticated cyber defense techniques. The Tularosa Study, was designed and conducted to understand how defensive deception, both cyber and psychological, affects cyber attackers Ferguson-Walter et al. [2019c]. More specifically, for this empirical study, cyber deception refers to a decoy system and psychological deception refers to false information of the presence of defensive deception techniques on the network....

MOLECULAR DESIGN OF ORGANIC SEMICONDUCTORS FOR INTERACIAL AND EMISSIVE MATERIAL APPLICATIONS

Marcus Cole
This dissertation describes the synthesis and characterization of functional optoelectronically active materials. Synthetic techniques were used to prepare polymers containing perylene diimide (PDI) or tetraphenylethylene (TPE) moieties in the polymer backbone. PDI-based structures were prepared with embedded cationic or zwitterionic moieties intended to tailor organic/inorganic interfaces in thin film photovoltaic devices. The aggregation-induced emission (AIE)-active TPE polymers were synthesized to study how AIE properties evolve in π-conjugated polymers. The syntheses discussed here focused on modulation...

EFFICIENT HARDWARE PRIMITIVES FOR SECURING LIGHTWEIGHT SYSTEMS

Siva Nishok Dhanuskodi
In the era of IoT and ubiquitous computing, the collection and communication of sensitive data is increasingly being handled by lightweight Integrated Circuits. Efficient hardware implementations of crytographic primitives for resource constrained applications have become critical, especially block ciphers which perform fundamental operations such as encryption, decryption, and even hashing. We study the efficiency of block ciphers under different implementation styles. For low latency applications that use unrolled block cipher implementations, we design a glitch...

Bandwidth Bounds of Infinite Planar Array Elements

Hsieh-Chi Chang
For elements of an infinite planar phased array in free space and an infinite conductor-backed free standing planar phased array, fundamental bandwidth bounds are derived from the optical theorem for periodic scatterers. The bounds are based on Gustafsson’s theory of fundamental bandwidth limits for electrically small antennas of arbitrary shape, but extended to periodic configurations. The element bandwidth bound is found to be a function of the strengths of the induced static dipole moments in...
