- A stroke occurs when blood flow in the brain is impaired and often causes damage to corticospinal tract projections that control the muscles of the upper-extremity. Due to this damage, 50-70% of stroke survivors experience long-term upper-extremity functional deficits(Faria-Fortini, Michaelsen, Cassiano, & Teixeira-Salmela, 2011). These deficits result from motor impairments...

- 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:
- Political leaders often engage in open fights for recognition, announcing that some crucial element of their state’s identity, status, or history, has not been properly acknowledged and respected in the conduct of diplomacy. Among international relations scholars, these instances are usually ascribed to the fact that states, like individuals, need...

- Description:
- Slow-wave sleep (SWS) is important for overall health since it affects many physiological pathways from cardio-metabolic health to cognitive function. Sleep and autonomic nervous system (ANS) functioning are closely coupled at anatomical and physiological levels. Sleep-related changes in ANS function are likely the main pathway through which SWS affects many...

- Description:
- Phononic crystals and acoustic metamaterials exhibit unique wave propagation properties rising from periodicity and the heterogeneity in material/structure design. One important property is tailoring the propagation of elastic waves from band gaps in such systems – frequency ranges of strong wave attenuation. This thesis first explores the idea of gaining...

- 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...

- Platelets are circulating anucleate discs derived from megakaryocytes, and play major roles in hemostasis, inflammation, thrombosis, and vascular biology. Multi-phase culture systems for inducing in vitro platelet production from mature megakaryocytes have been explored to allow progenitor expansion, megakaryocyte maturation, and promotion of platelet formation and shedding. In this thesis,...
