a subgroup h of a group g is called inert if‎, ‎for each $gin g$‎, ‎the index of $hcap h^g$ in $h$ is finite‎. ‎we give a classification ‎of soluble-by-finite groups $g$ in which subnormal subgroups are inert in the cases where $g$ has no nontrivial torsion normal subgroups or $g$‎ ‎is finitely generated‎.

Today, the h-index is a widely accepted indicator of scientific performance and has become a built-in feature of bibliographic databases such as the Web of Science (Thomson Reuters) and Scopus (Elsevier) (van Eck & Waltman, 2008). The wide acceptance is due mainly to the many advantages of the new index. These include its simplicity and intuitive meaning (Franceschini & Maisano, 2010), the comb...

objective(s): iodine-123 metaiodobenzylguanidine (123i-mibg) myocardial scintigraphy has been used to evaluate cardiac sympathetic denervation in lewy body disease (lbd), including parkinson’s disease (pd) and dementia with lewy bodies (dlb). the heart-tomediastinum ratio (h/m) in pd and dlb is significantly lower than that in parkinson’s plus syndromes and alzheimer’s disease. although this ra...

The h-­‐index can be a useful metric for evaluating a person’s output of Internet media. Here we advocate and demonstrate adaption of the h-­‐index and the g-­‐index to the top video content creators on YouTube. The h-­‐index for Internet video media is based on videos and their view counts. The index h is defined as the number of videos with ≥ h×105 views. The index g is defined as the number ...

the scientific output of a researcher includes academic publications, creditability of these publications and number of citations. universities and institutions evaluating the research activities have always taken into account the academic status and ranking of the researchers. selection and application of an appropriate method to assess the academic activities have also been a concern for scie...

The h-index is a citation-based metric with extensive applications, and several variants have been developed to complement it. This study formulates the optimal growth path (OGP) models of selected h-like indexes, that is, h-index, g-index, A-index, R-index, e-index, analyzes their OGP-allocated strategies citations. It argued OGP useful tool for analyzing sensitivity these indexes Through simu...
