Essays on the Impact of Information Asymmetry

Myungkoo Song
This dissertation consists of three essays focusing on how information asymmetry affects agents’ behavior across different environments. The first essay characterizes the optimal contract when a firm can employ two incentive schemes, promotion and pay for performance, simultaneously (Chapter 2). In the second essay, I study how information asymmetry can lead a firm to choose a less profitable short-term over a more profitable long-term project (Chapter 3). The other essay analyzes a career choice problem...

Everett Carlyle Edwards
Pliocene conglomerates of the Los Angeles basin and their paleographic significance: The Los Angeles Basin of southern California is 50 miles long and 25 miles wide, and is bounded by the Pacific Ocean, the Santa Monica, San Gabriel and Santa Ana Mountains and the Ferris Block. It contains an enormous thickness of Miocene, Pliocene and Pleistocene strata. Physical conditions of origin and the nature of sediments are as closely related as cause and effect. Since...

Convex Relaxation for Low-Dimensional Representation: Phase Transitions and Limitations

Samet Oymak
There is a growing interest in taking advantage of possible patterns and structures in data so as to extract the desired information and overcome the curse of dimensionality. In a wide range of applications, including computer vision, machine learning, medical imaging, and social networks, the signal that gives rise to the observations can be modeled to be approximately sparse and exploiting this fact can be very beneficial. This has led to an immense interest in...

The Colorado River - a Source of Water and Power for Los Angeles

Max W. Moody
The rapid growth and development of Los Angeles City and County has been one of the phenomena of the present age. The growth of a city from 50,600 to 576,000, an increase of over 1000% in thirty years is an unprecedented occurrence. It has given rise to a variety of problems of increasing magnitude. Chief among these are: supply of food, water and shelter development of industry and markets, prevention and removal of downtown congestion...

Thermalization in Periodically-Driven Interacting Quantum Systems

Karthik Iyengar Seetharam
Periodically-driven (Floquet) quantum systems are ubiquitous in science and technology. For example, when a laser illuminates a material or an AC voltage is applied to a device, the system is well-described by a time-periodic Hamiltonian. In recent years, periodic driving has been proposed, not just as a tool to excite and probe devices, but actually as a mechanism of engineering new phases of matter, some of which have no equilibrium analog. However, with this promise...

Microbial Evolution and the Rise of Oxygen: The Roles of Contingency and Context in Shaping the Biosphere through Time

Lewis Michael Ward
We are shaped by our environment, but we then shape it in turn. This interplay between life and the Earth, and how these interactions have shaped both parties through time, is the heart of the discipline of geobiology. My research is fundamentally motivated by a desire to understand how life and the Earth have changed together through time to reach the state that they’re at today, and to understand from this history how the coevolution...

Effect of Auxin on Chlorella vulgaris and Studies on the Movement of Leaves

Hung-Chang Yin
[Part 1] Chlorella vulgaris of a re-isolated clone was cultured in Knop's solution to which different amounts of pure heteroauxin were added. The results show that auxin promotes the enlargement of the individual cells. Particularly in the young cultures the cell volume is proportional to the logarithm of the auxin concentration. In older cultures the matter is complicated by the shortage of another factor, presumably food. At high concentrations auxin retards cell division. This probably...

Measurement of the Neutron Beta Decay Asymmetry using Ultracold Neutrons

Michael Praetorius Mendenhall
The free neutron beta decay correlation A0 between neutron polarization and electron emission direction provides the strongest constraint on the ratio λ = gA/gV of the Axial-vector to Vector coupling constants in Weak decay. In conjunction with the CKM Matrix element Vud and the neutron lifetime τn, λ provides a test of Standard Model assumptions for the Weak interaction. Leading high-precision measurements of A0 and τn in the 1995-2005 time period showed discrepancies with prior...

Studies of the N-End Rule Pathway in Saccharomyces cerevisiae

Anna Shemorry
Many intracellular proteins are either conditionally or constitutively short-lived, with in vivo half-lives that can be as brief as a few minutes. The regulated and processive degradation of intracellular proteins is carried out largely by the ubiquitin (Ub)-proteasome system (UPS). In eukaryotes, the N-end rule pathway is a part of the UPS. The N-end rule relates the regulation of the in vivo half-life of a protein to the identity of its N-terminal residue. Degradation signals...

The Equivalent Conductance of Solutions of Picric Acid

Frank Russell Capra
Picric acid possesses the property, which is rare among strong electrolytes, of having a convenient distribution ratio between water and certain organic solvents such as benzene, chloroform, etc. Because of this property, picric acid offers peculiar advantages for studying the well known deviations of strong electrolytes from the law of mass action, for; by means of distribution experiments, the activities of picric acid in various aqueous solutions may be compared. In order to interpret the...

Synthesis, NMR Solution Structure, and Neuritogenic Activity of Chondroitin Sulfate D and E

Kuang-Wei Yang
Chondroitin sulfate are ubiquitously expressed linear, sulfated polysaccharides that play critical roles in neuronal development and regeneration growth factor signaling, morphogenesis, and virus invasion. The diverse sulfation patterns presented by chondroitin sulfate has been suggested to regulate its activity, but the structural complexity and heterogeneity have hampered the understanding of structure-activity relationship. Therefore, we envisioned that chemically synthesized chondroitin sulfate oligosaccharide may provide a unique opportunity to specifically study the functions of sulfation patterns. Here,...

Bioorthogonal Noncanonical Amino Acid Tagging for Selective Analysis of the Pseudomonas aeruginosa Proteome

Brett Michael Babin
In natural environments, bacterial physiology is frequently characterized by slow metabolic rates and complex cellular heterogeneities. The opportunistic pathogen Pseudomonas aeruginosa provides one such example; P. aeruginosa forms untreatable chronic biofilm infections of the cystic fibrosis lung, where oxygen limitation can lead to states of metabolic dormancy. To better understand the biology of these states, in vitro experiments must be adapted to better recapitulate natural settings. However, low rates of protein turnover and cellular or...

The Design and Synthesis of Transition Metal Complexes Supported by Non-innocent Ligand Scaffolds for Small Molecule Activation

Kyle Tadashi Horak
This dissertation focuses on the incorporation of non-innocent or multifunctional moieties into different ligand scaffolds to support one or multiple metal centers in close proximity. Chapter 2 focuses on the initial efforts to synthesize hetero- or homometallic tri- or dinuclear metal carbonyl complexes supported by para-terphenyl diphosphine ligands. A series of [M2M’(CO)4]-type clusters (M = Ni, Pd; M’ = Fe, Co) could be accessed and used to relate the metal composition to the properties of...

Computational and Neural Mechanisms Underlying Decision-Making in Humans

Ryo Adachi
How do we make economic decisions in everyday life? How do we make decisions in the face of uncertainty regarding the statistics of the environment? These are the questions that played a pivotal role in the formation of the field "Decision Neuroscience". In each chapter of this thesis, we investigated the computational and neural mechanisms to tackle these questions using behavioral and neural data acquired through fMRI experiments. In the first chapter, we investigated the...

Structural Basis of DNA Recognition by Synthetic Ligands

Clara Louise Kielkopf
The DNA double helix presents functional groups in the major and minor grooves that can be used by ligands for readout of the base pair sequence. The overall flexibility and shape also distinguishes various sequences. Although the information displayed in the major groove is more diverse, small DNA-binding polyamides predictably distinguish all four base pairs in the minor groove. In this work, the structural basis of this recognition has been studied using x-ray crystallographic techniques,...

Geology of the Ravenna Quadrangle

Richard Henry Jahns
The Vasquez Series, composed of coarse fanglomerates, finer sandstones, and lavas, represents sub-areal deposition in the form of a series of rapidly coalescing alluvial fans. These fans were formed in a basin entirely local in character (confined to the Ravenna and Lang Quadrangles) which was probably caused by faulting, either in late Oligocene or very early Miocene time. The sediments are early or early middle Miocene in age, are very well consolidated, poorly sorted, and...
