Dominant species predict plant richness and biomass in global grasslands por Zhang,  Pengfei, Seabloom, Eric William, Foo,  Jasmine, MacDougall, Andrew S., Harpole, William Stanley, Adler, Peter B., Hautier, Yann, Eisenhauer, Nico, Spohn, Marie, Bakker, Jonathan D., Peri, Pablo Luis, Borer, Elizabeth T.

“…Three types of simulated data further show the generality of these results. Our integrative framework, arising from a few dominant species and mathematical properties of species abundance distributions, fills a persistent gap in our ability to predict community richness and biomass under ambient and anthropogenically altered conditions.…”

Routing field channels through a tertiary unit with heterogeneous fields por Anwar, Arif A., Bhatti, Muhammad Tousif

“…This paper develops a mathematical model/algorithm for routing the field channel along the existing field boundaries such that every field is serviced by a field channel and minimizing the total length of the field channel as a proxy measure of the cost of construction of field channels. …”

Estimating a social accounting matrix using entropy difference methods por Robinson, Sherman, El-Said, Moataz

“…Since the input-output accounts are contained within the SAM framework, updating an input-output table can be viewed as a special case of the general SAM estimation problem. The paper presents the structure of a SAM and a mathematical description of the estimation problem. …”
