- Description:
- Arising from the study of multiple ergodic averages, nilsequences and multiple correlation sequences lie at the crossroads of ergodic theory, combinatorics and number theory. We study these types of sequences along various subsequences of integers, and provide applications to ergodic theory and harmonic analysis. Our first result involves multiple correlation...

- Description:
- Inflammasomes are intracellular multiprotein signaling complexes that link Pathogen Associated and Danger Associated Molecular Patterns (PAMPs and DAMPs) by Pattern Recognition Receptors (PRRs) to the activation of Caspase-1, leading to the secretion of pro-inflammatory cytokines interleukin (IL)-1β and IL-18, and the induction of pyroptosis. Nucleotide-binding oligomerization domain (NOD)-like containing a...

- Description:
- Excess loading of reactive nitrogen and phosphorus into the environment from human activities has resulted in widespread eutrophication and the degradation of surface water quality and wildlife habitat. Wastewater is the dominant point source of nutrient loading into waterways, and thus represents a critical opportunity for treatment and prevention of...

- Description:
- Although flowing granular materials have been formally studied for over two hundred years, their behavior is still poorly understood relative to fluids, solids, and gases. Sheared granular materials with differing particle properties (e.g., size, density, shape) segregate (de-mix) due to percolation (small particles fall between large ones) and buoyancy (light...

- Description:
- Respiratory-swallow coordination is implicated as an essential component of safe and efficient swallowing, yet current evidence is incomplete regarding its relevance to swallowing impairment, assessment and treatment. Three studies were conducted that: 1) characterized and confirmed the optimal respiratory-swallowing coordination patterns in healthy adults, 2) identified linkages between deviations in...
