Modelling, Control and Estimation Techniques For Micromachined Electrostatic Actuators Using Macro Magnetic Actuators
(2016-07-29)
Parallel plate actuators (PPAs) are fundamental devices in micro-electro-mechanical systems. PPAs' main drawback is their limited open loop stable traveling range which is caused by their nonlinear electrostatic force. ...
Insomnia drives changes in suicide ideation: A latent difference score model of community adults over a brief interval
(2016-07-29)
Insomnia is robustly associated with suicidal behavior (Bernert, Kim, Iwata, & Perlis, 2015), but limitations in existing studies hinder nuanced understanding of this relationship. The current study aimed to address ...
The Role of Frataxin in Doxorubicin Mediated Cardiac Hypertrophy
(2016-07-29)
Doxorubicin (DOX) is a highly effective anti-neoplastic agent, used to treat a wide range of cancer. However, the clinical application of DOX is limited due to its dose dependent cardiotoxic complications which eventually ...
Lowest Price Guarantee Policies on Travel Websites: A Comprehensive Study on Policy Variety, Policy Costs, and Customer Perceived Value of Key Policy Features
(2016-07-29)
According to eMarketer (2015), approximately 60% of travel product purchases are made online, a figure that will continue to increase due to the widespread use of smartphones and the booming of mobile device booking. To ...
Magnetometer Aided Navigation Filters for Improved Observability and Estimation on Ground Vehicles
(2016-07-29)
Two modified extended Kalman filters, called the MGVA and MVVA filters, have been developed which combine the attitude determination capabilities of magnetometers with the standard extended Kalman filter. The standard ...
The Fractional Chromatic Number and the Hall Ratio
(2016-07-29)
All graphs in this paper are both finite and simple. α(G) is the vertex independence of a graph, G. The Hall ratio of G is defined as ρ(G) = max[n(H) /α(H) |n(H) = |V (H)|and H ⊆ G] where H ⊆ G means that H is a subgraph of ...
Characterization of the gut and skin microbiomes of wild-caught fishes from Lake Guntersville, Alabama
(2016-07-29)
In recent years, a paradigm shift has occurred in the area of organismal health. Where Koch and Hill’s fundamental postulates equating to “one microbe—one disease” were once regarded as the rule, research has now shifted ...
Mediterranean Diet Adherence in the Southeast United States: Validation of a Field-Based Survey Instrument and the Impact of Nutrition Knowledge
(2016-07-29)
The Mediterranean diet (MD) has been shown to reduce chronic disease risk, and nutrition knowledge has been shown to correlate with diet choices. However, Mediterranean diet adherence in the southeast United States is ...
Methane Exchanges between Terrestrial Ecosystems and the Atmosphere in Response to Multiple Environmental Changes - A Process-Based Modeling Study
(2016-07-29)
Methane (CH4), the most abundant non-carbon dioxide (CO2) greenhouse gas, has a relatively shorter lifetime (approx. 9 years) and higher global warming potential (approx. 28 times) than CO2 at a 100-year time horizon. The ...
Diversity and Conservation of the Southern Cavefish, Typhlichthys subterraneus
(2016-07-29)
The Southern Cavefish, Typhlichthys subterraneus, is one of the most fascinating stygobionts of the Amblyopsidae due to undescribed diversity within it. I investigated aspects of morphological and molecular diversity for ...
Advancing a better understanding of influences on relational health: A prevention science approach
(2016-07-28)
One of the strongest predictors of optimal health, well-being, and life satisfaction is having stable and supportive relationships (Pinker, 2014). Yet as evidenced by high rates of relationship dissolution, maintaining ...
