Warren Weaver’s scientific contributions

... Vielmehr handelt es sich dabei um »eine Form der Verhandlung zwischen Menschen bezüglich des Inhalts und der Bedeutung ihres Kommunikationsprozesses« (Rüggenberg 2007: 20). 29 23 Aus mathematischer Perspektive sind hier Cherry (1952) oder Shannon und Weaver (1976), aus sozialwissenschaftlicher Merten (1977) oder Graumann (1972) sowie aus linguistischer Fiehler (1990) oder Martinich (1984) zu nennen. 24 Wenn Kommunikationspartner miteinander in Verbindung treten, tauschen sie etwas aus. ...

... In contrast, the other alpha diversity indices used in this study do not consider the phylogeny of the taxa. The observed OTUs quantify species richness or the number of taxa [53], while the Shannon index combines richness and the relative abundance of taxa [54]. The Pielou evenness index considers the number of individuals or, in this case, sequences that belong to each taxon present in a sample [55]. ...

... This step is important to calculate alpha diversity index "faith_pd" (Faith, 1992) with "qiime diversity alpha-phylogenetic" plotted as rarefaction curves. Additionally, we calculated observed features as well as the Shannon index (Shannon & Weaver, 1949). Statistical analyses for alpha diversity were done using "qiime diversity alpha-group-significance" script in QIIME2, which uses a non-parametric t-test with Monte Carlo permutations (Bolyen et al., 2019). ...

... Many works have studied the parameters of the Duffing oscillators [32,33]. Control of these parameters is important because if the ideal values are found for each case, interesting phenomena emerge in the coupling of these nonlinear systems and it is possible to implement in different areas of science such as control of intermittency on-off [34], telecommunications [35,36], etc. ...
