MY EYES DUE SEE

My Eyes Due See is a multidimensional examination of the “black experience” in America. The installation is composed of a single-channel video, a music composition that utilizes music samples and live instrumentation, and sculptures made up of car parts and broomsedge grass. Each of these elements arranged in space share a nuanced and complicated view of blackness through the lens of a black man decoding personal history and American history simultaneously. Autonomy is the overarching theme throughout the work as it pertains to race, identity, urban and rural environments, and the relationship between generational trauma and nostalgia

Electrode geometry and preferential stimulation of spinal nerve fibers having different orientations: a modeling study

In a computer modeling study of epidural spinal cord stimulation using a longitudinal array of electrode contacts, the effect of contact geometry and contact combination on the threshold voltages for stimulation of dorsal column (DC) fibers and dorsal root (DR) fibers was investigated. It was concluded that DC-fiber stimulation will be favoured when a tripolar combination and small contact length and spacing are used, while DR-fiber stimulation will be favoured when unipolar stimulation and large contact length are used

Extraordinary exciton conductance induced by strong coupling

We demonstrate that exciton conductance in organic materials can be enhanced by several orders of magnitude when the molecules are strongly coupled to an electromagnetic mode. Using a 1D model system, we show how the formation of a collective polaritonic mode allows excitons to bypass the disordered array of molecules and jump directly from one end of the structure to the other. This finding could have important implications in the fields of exciton transistors, heat transport, photosynthesis, and biological systems in which exciton transport plays a key role.Comment: Main text: 5 pages, 4 figures; Supplemental: 2 pages, 1 figure.

Dark Matter and The Anthropic Principle

We evaluate the problem of galaxy formation in the landscape approach to phenomenology of the axion sector. With other parameters of standard LambdaCDM cosmology held fixed, the density of cold dark matter is bounded below relative to the density of baryonic matter by the requirement that structure should form before the era of cosmological constant domination of the universe. Galaxies comparable to the Milky Way can only form if the ratio also satisfies an upper bound. The resulting constraint on the density of dark matter is too loose to select a low axion decay constant or small initial displacement angle on anthropic grounds.Comment: 17 pages, 1 figur
