  • Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

    Creator:
    Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
    Abstract:
    Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

  • Detecting Fish Vocalizations in American Samoa Using Machine Learning

    Creator:
    Munger, Jill
    Abstract:
    A deep neural network was developed and trained to identify the sounds of pomacentrids (damselfishes) in the National Park of American Samoa. Four years of continuous, passive acoustic data were recorded by a single stationary hydrophone. Deep neural networks enable the full utilization of such large datasets by automating laborious...

  • A Study of Charging Behaviors in Organic Semiconductors using Optical Trapping

    Creator:
    Founds, Graham M.
    Abstract:
    We measure the charging and discharging of two organic materials, PCBM and ADT-TES-F. These materials are studied through the noncontact method of particle trapping known as Optical Tweezers, where an IR laser is used to constrain the motion of a coated or noncoated silica sphere while its positional data is...

  • Freezing a Softly Repulsive Fluid : Monte Carlo Methods and the Weeks-Chandler-Andersen Potential

    Creator:
    May, Christopher
    Abstract:
    The equation of state for a fluid described by the Weeks-Chandler-Andersen (WCA) potential was solved to determine at what pressures and temperatures the fluid will theoretically freeze. A Monte Carlo (MC) algorithm was used to sample a system of 256 spheres for a set of thermodynamic averages to locate and...

  • Drunken Walking: A Novel Brownian Dynamics Simulation for the Mechanochemical Cycle of the Dynein Motor Protein

    Creator:
    Waczak, John L.
    Abstract:
    The dynein molecule is a peculiar motor protein recognized for its unique stepping behavior. Sometimes it steps forwards. Other times it steps backwards. It has even been observed to occasionally shuffle by beginning a step with the same domain many times in row. These motions make dynein an interesting object...

  • Simulating the Dynein Motor Protein: A Monte Carlo Approach to Achieve Coordinated Stepping

    Creator:
    Kiatvongcharoen, Jin
    Abstract:
    The motor protein dynein is responsible for cellular processes such as axonal transport and cell division by delivering vital information along the microtubule track. A failed delivery can cause severe damage to the cell’s functionality and lead to neurological diseases. Despite dynein’s rich history in cellular research, the mechanism of...

  • Fabrication and low-temperature measurement of quantum devices

    Creator:
    Nichols, Dublin M.
    Abstract:
    Since the advent of graphene, research on 2D materials has exploded. Countless experiments have uncovered novel properties that emerge when different layered crystals are cleaved down to only a few atomic layers in thickness. The most popular of these non-graphene 2D materials is MoS2, a semiconductor which has been of...

  • Brewing in the Medieval Period - How Beer and Ale Developed into a Commercial Industry

    Creator:
    Abbott, Marshall
    Abstract:
    This article analyzes how this transition occurred and what significant developments took place that allowed beer and ale to become a tradable and profitable good on the European market. Specifically, it examines the development of brewing as a tripartite progression: (a) that beer and ale were brewed in the 3...
