DOI: 10.1007/s12517-020-05397-5
Abstract: The coal seams in Kuba coalfield are near-vertical distributed, and the composition of the seepage channel and gas–water differentiation is quite different from that of the horizontal coal seam. By using high-precision tectonic fracture mapping… read more here.

DOI: 10.1016/j.expthermflusci.2020.110235
Abstract: Abstract Because wire-meshes have a great potential application for designing high-efficient heat and mass transfer systems, a deformable bubble of Re ~ 800 rising in still tap-water near a vertical mesh of different porosity is studied using… read more here.

DOI: 10.1109/map.2019.2943313
Abstract: Near-vertical-incidence skywave (NVIS) propagation is defined as providing continuous coverage from nearly 0 km (just beyond the line of sight) to a couple hundred kilometers from the transmitter with no skip or dead zones. NVIS… read more here.

DOI: 10.1121/1.5014748
Abstract: Most previous research on sound propagation in the atmosphere has focused on nearly horizontal propagation paths, with the sources and receivers close to the ground. Along such paths, refraction by wind and temperature gradients, and… read more here.

DOI: 10.1364/ao.446610
Abstract: Near vertical optically trapped dimers, composed of pairs of microspheres, and constructed in situ, were imaged in bright-field in flow and at rest, and with displacement Δz from the transverse xy imaging plane of an… read more here.
