Particle-in-Cell Simulations Examining AK Gap Closure Mechanisms in the Pinch Reflex Diode
Gap closure mechanisms in the pinch reflex diode are studied using cylindrical, two-dimensional, fully kinetic, electromagnetic, particle-in-cell simulations. The key physical dimensions in the model are based on the Mercury accelerator at the Naval Research Laboratory in Washington, DC. Simulation …

Modeling gap closure within vaporizing transmission lines of pulsed power machines using particle-in-cell direct simulation Monte Carlo (PIC-DSMC)
… (ES) and Dual Grids - was studied for modeling gap closure within an overall DSMC-PIC approach. Gap closure is a difficult computational problem due to massive gradients in density and electrostatic properties, extreme regime (relativistic electrons), and highly nonequilibrium characteristics. …

On the ecology of Acer circinatum Pursh: a study of factors that affect the distribution of a small hardwood tree within oldgrowth forests in southwestern British Columbia, Canada
… was able to delay but not completely repress gap closure in gaps it occupied.

Growth of advanced European beech trees in the transformation phase in the southern Black Forest
… height and crown width, and their importance to gap closure simulation. <br> <br>Although some of the specifics of the analyses are lost when generalizations are made, taken all together, the results suggest the following broad conclusions: the basal area increment of advanced aged European beech …

The Role of Interleukin-10 Family Members in Inflammatory Skin Diseases. Understanding the mechanism of action of interferon lambda and interleukin-22 on human primary keratinocytes and dermal fibroblasts with a focus on healing responses in inflammatory skin diseases
… and CLE keratinocytes. Cell proliferation and gap closure were investigated in skin resident cells using cell trace dye and scratch assay. Dermal fibroblasts were assessed for the presence of IFNλR1 and IL-22R1, downstream activities of the receptors. Results showed that IL-22 accelerated …

Effect of interfacial thermal conductance and fiber orientation on the thermal diffusivity/conductivity of unidirectional fiber-reinforced ceramic matrix composites
… nitridation. The formation of an interfacial gap at the interface due to thermal expansion mismatch between the fiber and the matrix in reference and HIP'd composites, and removal of carbon coating for oxidized composites, resulted in the dependence of thermal diffusivity/conductivity on the …

TCAP Scores and Per Pupil Expenditures: Statewide Changes Before and After Tennessee’s First to the Top Act
… accountability for student achievement and gap closure brought a climate of pressure and tension.</p> <p>Secondary data were readily available on the Tennessee Report Card from TDOE’s website (www.tn.gov/education). Data from each LEA were collected, organized, and analyzed in the areas of …

An assessment of silicon carbide as a cladding material for light water reactors
… higher burnup. However, due to lack of early gap closure by creep as well as the lower conductivity of the cladding, the fuel will experience higher temperatures than with zircaloy cladding. Several options were explored to reduce the fuel temperature, and it was concluded that annular fuel …

A Suspended Fiber Network Platform for the Investigation of Single and Collective Cell Behavior
… to report a new wound healing assay to examine gap closure. We found that gaps spanned by crosshatch network of fibers closed faster than those on parallel fibers and importantly, we reported that gaps of 375 µm or larger did not close over a 45-day period. In summary, the methods and novel …

How did Listeria monocytogenes become pathogenic?
… for 10 per cent of the labor intensive gap-closure and annotation efforts, which I helped coordinate. General information and comparisons with sister species L. innocua and a close Gram positive relative Bacillus subtilis are presented in context. The areas I personally investigated, …
