Hartmann Flow With Braginsky Viscosity: A Test Problem For Plasma In The Intracluster Medium, M. Lyutikov
Hartmann Flow With Braginsky Viscosity: A Test Problem For Plasma In The Intracluster Medium, M. Lyutikov
Department of Physics and Astronomy Faculty Publications
We consider a Hartmann layer, stationary flow of a viscose and resistive fluid between two plates with superimposed transverse magnetic field, in the limit of gyrotropic plasma, when viscosity across the field is strongly suppressed. For zero cross-field viscosity, the problem is not well posed, since viscosity then vanishes on the boundaries and in the middle of the layer, where there is no longitudinal field. An additional arbitrarily small isotropic viscosity allows one to find magnetic field and velocity profiles that are independent of this viscosity floor and different from flows with isotropic viscosity. Velocity sharply rises in a thin …

CTRC Research Publications
Microfluidics-based cell assays offer high levels of automation and integration, and allow multiple assays to be run in parallel, based on reduced sample volumes. These characteristics make them attractive for studies associated with drug discovery. Controlled delivery of drug molecules or other exogenous materials into cells is a critical issue that needs to be addressed before microfluidics can serve as a viable platform for drug screening and studies. In this study, we report the application of hydrodynamic focusing for controlled delivery of small molecules into cells immobilized on the substrate of a microfluidic device. We delivered calcein AM which was …
A Bottom-Up Redefinition For Mobility And The Effect Of Poor Tube-Tube Contact On The Performance Of Cnt Nanonet Thin-Film Transistors, N. Pimparkar, M. A. Alam
A Bottom-Up Redefinition For Mobility And The Effect Of Poor Tube-Tube Contact On The Performance Of Cnt Nanonet Thin-Film Transistors, N. Pimparkar, M. A. Alam
Department of Electrical and Computer Engineering Faculty Publications
Nanonet thin-film transistors (NN-TFTs) based on random or aligned networks of single-wall carbon nanotubes are often regarded as a promising high-performance alternative to amorphous-Si technology for various macroelectronics applications involving sensors and displays. The comparison of NN-TFTs with other competing technologies such as organic, a-Si, and p-Si TFTs, however, has proved difficult as the mobility of these devices (counterintuitively) depends on a host of geometrical parameters such as tube density D, tube length LS, channel length LC, tube-tube contact Cij, etc. In this letter, we redefine the mobility for NN-TFTs by generalizing the classical definition from a bottom-up perspective based …
Simulation Of Thermal Transport In Open-Cell Metal Foams: Effect Of Periodic Unit Cell Structure, S. Krishnan, S V. Garimella, J. Y. Murthy
Simulation Of Thermal Transport In Open-Cell Metal Foams: Effect Of Periodic Unit Cell Structure, S. Krishnan, S V. Garimella, J. Y. Murthy
CTRC Research Publications
Direct simulation of thermal transport in open-cell metal foams is conducted using different periodic unit-cell geometries. The periodic unit-cell structures are constructed by assuming the pore space to be spherical and subtracting the pore space from a unit cube of the metal. Different types of packing arrangement for spheres are considered—body centered cubic, face centered cubic, and the A15 lattice (similar to a Weaire-Phelan unit cell)—which give rise to different foam structures. Effective thermal conductivity, pressure drop, and Nusselt number are computed by imposing periodic boundary conditions for aluminum foams saturated with air or water. The computed values compare well …

Phase Coherence And Superfluid-Insulator Transition In A Disordered Bose-Einstein Condensate, Y. P. Chen, J. Hitchcock, D. Dries, M. Junker, C. Welford, R. G. Hulet
Department of Physics and Astronomy Faculty Publications
We have studied the effects of a disordered optical potential on the transport and phase coherence of a Bose-Einstein condensate (BEC) of Li-7 atoms. At moderate disorder strengths (V-D), we observe inhibited transport and damping of dipole excitations, while in time-of-flight images, random but reproducible interference patterns are observed. In situ images reveal that the appearance of interference is correlated with density modulation, without complete fragmentation. At higher V-D, the interference contrast diminishes as the BEC fragments into multiple pieces with little phase coherence.

Background: The ascomycete fungus Cercospora zeae-maydis is an aggressive foliar pathogen of maize that causes substantial losses annually throughout the Western Hemisphere. Despite its impact on maize production, little is known about the regulation of pathogenesis in C. zeae-maydis at the molecular level. The objectives of this study were to generate a collection of expressed sequence tags (ESTs) from C. zeae-maydis and evaluate their expression during vegetative, infectious, and reproductive growth. Results: A total of 27,551 ESTs was obtained from five cDNA libraries constructed from vegetative and sporulating cultures of C. zeae-maydis. The ESTs, grouped into 4088 clusters and 531 …

Department of Electrical and Computer Engineering Technical Reports
In many reliable Wireless Sensor Network (WSN) applications, messages have different priorities depending on urgency or importance. For example, a message reporting the failure of all nodes in a region is more important than that for a single node. Moreover, traffic can be bursty in nature, such as when a correlated error is reported by multiple nodes running identical code. Current communication layers in WSNs lack efficient support for these two requirements. We present a priority-driven communication layer, called SeNDORComm, that schedules transmission of packets driven by application-specified priority, buffers and packs multiple messages in a packet, and honors latency …
Volumetric Visualization Of Nexrad Level Ii Doppler Weather Data From Multiple Sites, Yi Ru
Volumetric Visualization Of Nexrad Level Ii Doppler Weather Data From Multiple Sites, Yi Ru
Purdue Polytechnic Masters Theses
Weather visualization is critical for operational forecasters and weather researchers to analyze, monitor, and predict severe weather events such as storms, tornadoes, and hurricanes. Usually measured weather datasets such as NEXRAD Level II radar data contain some errors and have temporal aliasing issues, so that the raw data cannot represent the true meteorological patterns. Existing weather visualization packages usually ignore these problems, thus they fail to unveil some detailed information and cannot meet the needs of professional meteorologists. Most displays generated by those packages are limited to 2D images, 3D point clouds, or iso-surfaces. Those displays are not able to …
