B.J. Johnson’s scientific contributions

... Schetz and Eichhorn [3] expanded the understanding by examining unsteady natural convection in the vicinity of a doubly infinite vertical plate, contributing to a broader scope of fluid dynamics. Park and Hyun [4] and later Park [5] shifted focus toward the transient behavior and buoyant flows of stratified fluids, which are crucial in understanding environmental and industrial processes. This trend continued with Shapiro and Fedorovich [6] who investigated the convective flows along a vertical plate immersed in a stably stratified fluid, providing insights relevant to atmospheric sciences and engineering applications. ...

... With global coverage and frequent repeat observations, satellite remote sensing technology is a particularly valuable tool in this respect, having proven an effective means of monitoring, mapping, and quantifying productivity and phenological changes in vegetation over time and across large scales (Briggs et al., 1997;Goodin and Henebry, 1997;Huete, 2016;Huang et al., 2018). Numerous studies have characterized vegetation phenology (i.e. the timing of recurring biological cycles, such as emergence of first leaf, senescence, growing season length) by exploiting time-series of remotely-sensed spectral vegetation indices (Zhang et al., 2006;Ganguly et al., 2010;Henebry and de Beurs, 2013;Broich et al., 2015;Wu et al., 2016;Richardson et al., 2018). ...

... There has been much interest in deriving formulas regarding the number of spanning trees of the K n -complements of different types of graph G. For instance, see the results for the cases when G is pK 2 [31], a star [26], a complete graph [2], a path [20], a cycle [15], a multi-star [6,23,34], a complete multipartite graph [27], a circular graph [35], and a quasi-threshold graph [21], respectively. In this paper, we focus on counting spanning trees of the K n -complements of a bipartite graph. ...
