- Description:
- Motor planning is fundamental to the performance of everyday reaching movements. The influence of planning is not limited to voluntary movements but extends to involuntary movements initiated in response to sensory stimuli, such as postural perturbations applied to the arm. Stroke alters voluntary reaching and the involuntary response to perturbations,...

- Description:
- This dissertation concerns the probabilistic aspects of diffusion processes generated by a family of differential operators, which is similar to the family of hypoelliptic Laplacian operators, acting on the tangent bundle of a compact Riemannian manifold. By lifting the processes to the product of the frame bundle and the euclidean...

Those are important metrics to a network, but...

- Description:
- Transport along and across the grain boundaries of solid-state electrolytes has implications for a broad range of materials and in an equally broad range of technologies. Over the past 2-3 decades, a substantial body of literature has been developed to explain grain boundary transport properties within the context of space...

- Autism spectrum disorder (ASD) is a heterogeneous disorder defined by core deficits in social communication as well as the presence of restricted interests and repetitive behaviors, including sensory processing atypicalities. Individuals with ASD also have atypicalities in integration of multiple sensory modalities (i.e., sensory integration), which are hypothesized to underlie...

- Drawing from the data I collected through nine months (between 2014 to 2017) of participant observations, 120 in-depth, semi-structured interviews, and archival work, the project explores the tactics that Chechen and Dagestani journalists utilize to resist state pressure and circumvent state-imposed censorship. Specifically, I explicate how these regional journalists in...

- Drawing on archival research and a new attention to literary form, Sion’s Muse argues that the religious poetry of the English Reformation decisively constituted new modes of devotional affect for laypeople. At the beginning of the English Reformation, the psalm translator Miles Coverdale wrote, “Would God that our minstrels had...

- Description:
- Neurodegenerative diseases (NDs) commonly involve the accumulation and aggregation of neurotoxic proteins that impair and ultimately destroy specific neurons. Considerable evidence from human and animal studies indicates that many NDs show disrupted circadian and sleep as symptoms. Yet little is known about the molecular mechanisms by which genes cause NDs...

- Description:
- The Brink-Schwarz superparticle is a one-dimensional analogue of the Green-Schwarz superstring. In this thesis, we use the Batalin-Vilkovisky formalism to study the superparticle. After proving a vanishing result for its Batalin-Vilkovisky cohomology, we explain the sense in which the superparticle exhibits general covariance in the world-line. Using techniques from rational...

- Description:
- Segregation of polydisperse granular materials remains to be a challenging problem in many industrial processes. However, most studies have focused either on bidisperse (two different particle size species) materials, which are not representative of most real mixtures, or on polydisperse materials in an idealized simple geometry. Additionally, most studies have...
