Cuscuta is the only parasitic genus in Convolvulaceae family. This genus is globally distributed, with most species in the tropics, subtropics, and some in the temperate regions. In this study, the micro-morphological features and molecular evidencesof 12 populations from three species of Cuscuta (C. australis, C. campestris,and C. chinensis) have been considered. In total, seven quantitative a...

Least squares trees, multidimensional scaling and Neighbor Nets are all different and popular ways of visualizing multi-dimensional data. The method of flexi-Weighted Least Squares (fWLS) is a powerful method of fitting phylogenetic trees, when the exact form of errors is unknown. Here, both polynomial and exponential weights are used to model errors. The exact same models are implemented for M...

We study how control over positions of nodes can be leveraged for obtaining desired levels of network connectivity and sensing coverage. To this end, we propose Neighbor-Every-Theta (NET) graphs defined as each node having at least one neighbor in every theta angle sector of its communication range. For θ < π, NET graphs are guaranteed to have an edge-connectivity of at least b 2π θ c even with...

Topology control, primarily concerned with ensuring desired levels of coverage and connectivity, is a vital selfconfiguration operation in unattended sensor networks. We present a classification of sensor network topologies and discuss their implications for topology control. Our main contribution is a unifying framework that forms a basis for tunable topology control in all classes of topologi...

We show that strong coupling between ions in an ultracold neutral plasma is limited by electron screening. While electron screening reduces the quasiequilibrium ion temperature, it also reduces the ion-ion electrical potential energy. The net result is that the ratio of nearest-neighbor potential energy to kinetic energy in quasiequilibrium is constant and limited to approximately 1 unless the ...
