Abstract: We present the results from our search for HI 21-cm absorption in a sample of 16 strong FeII systems ($W_{\rm r}$(MgII $\lambda2796$) $\ge1.0$ \AA\ and $W_{\rm r}$(FeII $\lambda2600$) or $W_{\rm FeII}$ $\ge1$ \AA) at $0.5 read more here.

Abstract: Systems thinking characterizes the paradigm needed to effectively design, maintain, and utilize systems. Prior work has shown that there is a language of systems thinking and that its presence can be quantified within text using… read more here.

Abstract: We obtain sufficient criteria for simplicity of systems, that is, rings $R$ that are equipped with a family of additive subgroups $R_s$, for $s \in S$, where $S$ is a semigroup, satisfying $R = \sum_{s… read more here.
