Recent MHD dynamo simulations for magnetic Prandtl number > 1 demonstrate that when MHD turbulence is forced with sufficient kinetic helicity, the saturated magnetic energy spectrum evolves from having a single peak below the forcing scale to become doubly peaked with one peak at the system (=largest) scale and one at the forcing scale. The system scale field growth is well modeled by a recent ...

Several rapid methods for compositional analysis of heavy oils by thin layer chromatography with flame ionization detection (FID-TLC) were investigated. Separating into four fractions, Saturates, Aromatics, Resins, and Asphalten, SARA analysis of heavy oils could be accurately performed by three stage development using n-hexane, toluene, and tetrahydrofuran. Detailed hydrocarbon type analysis o...

We analyze the problem of resolving two point-sources in case mutually coherent sources with arbitrary quantum statistics, mutual phase, relative and absolute intensity. use a sensitivity measure based on method moments compare direct imaging spatial mode demultiplexing, analytically proving advantage latter. show that demultiplexing saturates Fisher information, for all known cases, even non-G...

Recently, Rokni et al. [1,2] developed entropy-scaling based pseudo-component techniques to predict the viscosity and thermal conductivity of hydrocarbon mixtures fuels up high temperature pressure conditions using only two calculated or measured mixture properties (number average molecular weight hydrogen-to-carbon ratio). The models are accurate for many that do not contain branched compounds...

A saturated injector driver is a power transistor circuit that turns fully on, and electrically saturates for the entire duration of pulse width. This type better used with injectors having high resistance coils (12~16 Ohm). The advantage this generated heat dissipated through not circuit. circuitry simplified compared to peakand-hold (which requires sinks dissipate electrical load).

We investigate signatures of chaos and equilibration in the quantum Rabi model, which exhibits a phase transition when ratio atomic level-splitting to bosonic frequency grows infinity. show that out-of-time-order correlator derived from Loschmidt echo signal quickly saturates normal reveals exponential growth superradiant is associated with onset chaos. Furthermore, we effective time-averaged d...

– We study the superconductivity in 2D fermionic systems near antiferromagnetic instability, assuming that the pairing is mediated by spin fluctuations. This pairing involves fully incoherent fermions and diffusive spin excitations. We show that the competition between fermionic incoherence and strong pairing interaction yields the pairing instability temperature Tins which increases and satura...

Recombinant adenoviruses are used extensively as delivery vectors in clinical gene therapy and in molecular biology, but little is known about how the viral carrier itself contributes to cellular responses. Here we show that infection with an E1/E3-deleted adenoviral vector (Adv) sensitizes human epithelial cells to tumor necrosis factor (TNF)-induced apoptosis. To explore the mechanism of Adv-...

Utilizing an eigenfunction decomposition, we study the growth and spectra of energy in the vortical (geostrophic) and wave (ageostrophic) modes of a three-dimensional (3D) rotating stratified fluid as a function of ǫ = f/N , where f is the Coriolis parameter and N is the Brunt-Vaisala frequency. Throughout we employ a random large scale forcing in a unit aspect ratio domain and set these parame...
