Dynamical Heterogeneities and Cooperative Motion in Smectic Liquid Crystals

Using simulations of hard rods in smectic-A states, we find non-gaussian diffusion and heterogeneous dynamics due to the equilibrium periodic smectic density profiles, which give rise to permanent barriers for layer-to-layer diffusion. This relaxation behavior is surprisingly similar to that of non-equilibrium supercooled liquids, although there the particles are trapped in transient (instead of permanent) cages. Interestingly, we also find stringlike clusters of up to 10 inter-layer rods exhibiting dynamic cooperativity in this equilibrium state.Comment: 10 pages, 4 figure

Land Cover Inventory of the Niobrara River Watershed

The Niobrara River watershed covers a large area in northern Nebraska, and neighboring parts of South Dakota and Wyoming, and is an important component of statewide natural resources management. Under ongoing agreements with the U.S. Bureau of Reclamation (BoR), the Nebraska Game and Parks Commission are charged with the development of management plans for various BoR projects in the Niobrara River watershed in Nebraska. A detailed delineation of land use and land cover patterns was needed in order to define and implement effective management strategies

Mechanistic mathematical models: An underused platform for HPV research

Health economic modeling has become an invaluable methodology for the design and evaluation of clinical and public health interventions against the human papillomavirus (HPV) and associated diseases. At the same time, relatively little attention has been paid to a different yet complementary class of models, namely that of mechanistic mathematical models. The primary focus of mechanistic mathematical models is to better understand the intricate biologic mechanisms and dynamics of disease. Inspired by a long and successful history of mechanistic modeling in other biomedical fields, we highlight several areas of HPV research where mechanistic models have the potential to advance the field. We argue that by building quantitative bridges between biologic mechanism and population level data, mechanistic mathematical models provide a unique platform to enable collaborations between experimentalists who collect data at different physical scales of the HPV infection process. Through such collaborations, mechanistic mathematical models can accelerate and enhance the investigation of HPV and related diseases

Real-Time Simulation of small-scale power grids with software in-the-loop and hardware in-the-loop experiments

As the term “Smart Grid” defines, the electricity supply network uses smart devices to monitor the state quantities, and digital communication technologies to support fast decisions and control. This work is focused on developing a flexible IoT architecture to support real-time tests and to validate some algorithms for monitoring and maintenance of micro-systems as intelligent smart functions on the virtual model of a small-scale power grid, through Real-Time Simulation Software in-the-loop (SIL) and Hardware in-the-loop (HIL). We aim to explain the implementation aspects of a microgrid in MATLAB/Simulink, based on real grid data and “smart customers” as end-users (capable of exchanging data with the outside of the simulation environment), then compiled in Real-Time environment (RT-LAB software). The overall communication infrastructure relies on different protocols for the data exchange between grid and application components (TCP and MQTT protocol). Furthermore, the presence of an MQTT broker makes the architecture flexible, since it allows the integration of different services
