Surface Waves Extraction And Their Effect On Effective Material Parameters Of Metamaterials, Xiaoyan Y.Z. Xiong, Li (Lijun) Jun Jiang, Wei E.I. Sha

Electrical and Computer Engineering Faculty Research & Creative Works

We investigate the influence of the finite width of the metamaterial slabs. The surface waves excited in finite-width slabs are numerically extracted by the rigorous coupled-wave analysis method. The magnitudes and decay rates of surface waves are analyzed for different materials and geometries. A general homogenization method based on the analysis of appropriately defined macroscopic fields in metamaterial cells is proposed to retrieve the effective material parameters as functions of position. The effects of surface waves on effective material parameters are studied.

Optimization Of Fluorescent Imaging In The Operating Room Through Pulsed Acquisition And Gating To Ambient Background Cycling, Kristian J. Sexton, Yan Zhao, Scott C. Davis, Shudong Jiang, Brian Pogue

Dartmouth Scholarship

The design of fluorescence imaging instruments for surgical guidance is rapidly evolving, and a key issue is to efficiently capture signals with high ambient room lighting. Here, we introduce a novel time-gated approach to fluorescence imaging synchronizing acquisition to the 120 Hz light of the room, with pulsed LED excitation and gated ICCD detection. It is shown that under bright ambient room light this technique allows for the detection of physiologically relevant nanomolar fluorophore concentrations, and in particular reduces the light fluctuations present from the room lights, making low concentration measurements more reliable. This is particularly relevant for the light …

Detection Of Pheromone Laying Event In Foraging Data Of Harvester Ants Using Change Point Analysis Method, Safeeul Bashir Safee

Computer Science ETDs

Communication is an important factor in the foraging performance of social insects, such as ants. During foraging, ants keep track of food sources by using memory (site fidelity) or by communicating through pheromones. Previous field experiments showed that the rate of seed collection depends on the distribution of food in the environment. If food is spatially clustered, then it is beneficial for ants recruit nest mates to collect seeds from large clusters. However, we do not know when the recruitment occurs in natural ant population. To explore this question, we used a power law distribution to arrange seeds in piles …

Behavioral Sex Difference In Healthy Sprauge-Dawley Rats, Jeffrey Bagg, Jessica Obie, Fei Shang, Natalie Lista, Corinne Kiessling

Binghamton University Undergraduate Journal

Recently, the NIH has pushed for both sexes of a species to be incorporated into behavioral experiments. This push came as a result of an unchecked exclusion of females in experimentation. In rat studies, it is a common argument that females are more variable than males due to the presence of their estrous cycle. This study set out to evaluate this claim, and provide sex differences data for a variety of motor, anxiety, and cognitive behavioral tests. No sex differences in motor or anxiety behavior were found between the sexes. Males performed significantly better on the spontaneous alternation test of …
