- Description:
- We present two ways in which measures of information can be used for the design and analysis of neural networks in both the brain and the computer. In the brain, stimulus is often represented as a distributed pattern of activity in a network of neurons. The quality of such population...

- Description:
- This dissertation argues that royal nomadism, the custom whereby medieval rulers moved between many castles in a predetermined cycle, fundamentally affected the floorplan, use, and adornment of courtly built environments. This argument is a new departure for the study of castles. Scholars of medieval castles acknowledge that rulers passed through...

- Description:
- Thermoelectric materials have attracted widespread attention in recent decades because of their ability to directly convert thermal energy into electrical energy. Given that waste heat is the primary source of lost energy in the world, the implications of developing better thermoelectric materials are both immediate and far-reaching. Admittedly, large progress...

- Description:
- Cyclic loading, from earthquake, has caused the instability and failure of slopes composed of sensitive clays. During the 1964 9.2 moment magnitude (M) earthquake in Anchorage, Alaska, several slopes comprised of Bootlegger Cove Formation (BCF) clays failed during the strong seismic motion. Some researchers have proposed the use of residual...

- Description:
- New neurons are continuously produced in the subgranular zone of the dentate gyrus of the hippocampus throughout life. These newborn dentate granule cells (DGCs) undergo a stereotyped process of morphological and functional maturation during the first few weeks after differentiation that recapitulates some aspects of postnatal neuronal development. The inhibitory...

- Description:
- Frontotemporal Dementia (FTD) and Amyotrophic Lateral Sclerosis (ALS) are two devastating neurodegenerative diseases that affect 100,000s of people globally. They have a severe adverse impact on society, yet there are currently no early diagnostic tools or disease-modifying therapies available. Despite their clinical heterogeneity, evidence points to these diseases being on...

- Sub-wavelength matter’s interaction with far-field light is highly relevant for both fundamental scientific research, as well as many commercial, medical, and defense applications. For example, quantum computation depends on single identical photons produced by quantum dots characterized by far-field sources. Exoplanet detection uses cameras on Earth comprised of micron sized...

- This research questions how institutional logics shape and change through the event sequencing of institutional reforms. Literature reviewed on sequences of social events underspecifies the enchainment of events, i.e., the set of social processes that both links events and also renders the sequence meaningful beyond summing its individual events. My...

- Superconducting-circuit based platforms are strong contenders in the race to build a quantum computer.While the transmon has had extraordinary success as the leading superconducting qubit modality, there are reasons to believe that other types of qubits could possess relative benefits in terms of noise immunity, anharmonicity, or extensibility. In this...

- This work is composed of two separate projects that contribute to the field’s understanding of Neisseria gonorrhoeae genetics and physiology. First, I showed that N. gonorrhoeae mounts a substantial transcriptional program in response to hydrogen peroxide (HP), a prominent reactive oxygen species (ROS) encountered during infection. We measured which strain...

- “Coalitional Aesthetics” argues that leftist literary works of the 1930s enacted bonds of solidarity across racial, linguistic, and geographic divides, modeling alternative, non-hierarchical modes of social cohesion. Building on Gramsci’s concept of the coalitional, coalitional aesthetics refers to a set of formal characteristics that insist on the specificity of the...

- Dual-phase (DP) steels have been widely applied in automobile industry, and are famous for continuous yielding in their corresponding stress-strain curves. The appearance of yield-point phenomena, or discontinuous yielding, is considered undesirable for DP steels.
