- Description:
- Many industrial fluid flow problems involve the interaction between heavy, rigid objects and one or more fluid phases. For several decades, there has been a vested interest in simulating these fluid-structure interaction (FSI) problems in order to improve engineering design processes. However, numerical simulations of these problems can be challenging...

- Description:
- This dissertation explores ways to utilize physical parameters at the nanoscale interface to control the properties of mixed-dimensional heterojunctions (MDHJs). MDHJs combine the desirable properties of different classes of low-dimensional nanomaterials (materials that are quantum confined in at least one dimension). While MDHJs have achieved superlative performance for a variety...

- Description:
- In this thesis, we discuss classical and recent results around the damped wave equation on compact and noncompact manifolds. We firstly show that on asymptotically cylindrical and conic manifolds, the geometric control condition and the network control condition give exponential and logarithmic decay rates respectively. We then show that a...

- The theory of how humans and machines control and communicate with each other is at the core of the scientific field known as Human-Robot Interaction (HRI). Researchers in this sub-discipline of robotics are therefore particularly interested in developing methods to chuppahreduce the inherent friction in this communication and control channel....

- Description:
- Optical microscopy is one of the most ubiquitous tools for functional imaging of biological phenomena. While relatively non-destructive to living organisms, light microscopy’s spatial resolution is diffraction limited, restricting the minimum resolvable features. On the other hand, high resolution techniques such as electron microscopy or STORM, have several orders of...

- Stimulation of the cGAS-STING (cycle GMP-AMP synthase-Stimulator of Interferon Genes) pathway increases T cell activation and tracking into the tumor and reverses the immunosuppressive phenotype of myeloid cells. Direct targeting of the STING receptor using synthetic cyclic dinucleotide (CDN) ligands represents an attractive immunotherapeutic strategy for the treatment of lymphocyte-depleted...

- As conventional electronic materials approach the device scaling limits, new types of materials and structures have been examined for potential use in future electronic and optoelectronic applications including transistors, light emitting diodes, and solar cells. In recent years, atomically thin or two-dimensional (2D) transition metal dichalcogenide (TMD) materials have emerged...

- Store-operated Ca2+ entry (SOCE) is a principal mechanism for generating cellular Ca2+ signals. Store-operated Ca2+ release-activated Ca2+ (CRAC) channels serve an essential role in generating Ca2+ elevations needed for transcriptional, enzymatic, and secretory effector cascades in many cell types. CRAC channels, comprised of the ER Ca2+ sensor STIM and the...

- In monolayer materials with a honeycomb-like lattice an emergent degree of freedom arises for charge carriers corresponding to their valley index. Due to spatial inversion asymmetry and the presence of strong spin-orbit coupling, this valley degree of freedom strongly affects the optoelectronic properties of carriers in monolayer transition metal dichalcogenides...

- Description:
- Shoulder (glenohumeral joint) osteoarthritis causes pain, limits daily activities, and frequently requires joint replacement surgery. In shoulder osteoarthritis, the glenoid bone surface erodes in one of two ways: symmetrically (concentric deformity) or asymmetrically (eccentric deformity). Shoulder replacements in patients with eccentric deformities fail and require additional, revision surgery more often...
