We have identified outflows and bubbles in the Taurus molecular cloud based on the ∼100 deg Five College Radio Astronomy Observatory CO(1-0) and CO(1-0) maps and the Spitzer young stellar object catalogs. In the main 44 deg area of Taurus, we found 55 outflows, of which 31 were previously unknown. We also found 37 bubbles in the entire 100 deg area of Taurus, none of which had been found previo...

Higher–dimensional theories imply that some constants, such as the gravitational constant and the strength of the gauge–couplings, are not fundamental constants. Instead they are related to the sizes of the extra–dimensional space, which are moduli fields in the four– dimensional effective theory. We study the cosmological evolution of the moduli fields appearing in brane world scenarios and di...

This study focuses on the shape optimization of concrete gravity dams considering dam–water–foundation interaction and nonlinear effects subject to earthquake. The concrete gravity dam is considered as a two–dimensional structure involving the geometry and material nonlinearity effects. For the description of the nonlinear behavior of concrete material under earthquake loads, the Drucker–Prager...

Hydrodynamics analyses as a part of APEX (Advanced Power Extraction) study shows the possibility of applying swirling thick liquid walls to innovative confinement concepts such as Field Reversed Configuration (FRC), Spherical Torus (ST) and Heavy-Ion Fusion (HIF). This paper addresses the design and the hydrodynamic aspects of fusion relevant swirling flow including 3-D velocity distribution, v...

This paper experimentally quantifies the reorientation of the liquid-liquid interface between fluids of different densities flowing side-by-side in pressure-driven laminar flow in microchannels. A gravity-induced pressure mismatch at the interface will gradually drive the denser fluid to occupy the lower portion of the microchannel. The rate of this process is expected to depend on the interpla...
