Giant lobelias exemplify convergent evolution

open access: yesBMC Biology, 2010
Giant lobeliads on tropical mountains in East Africa and Hawaii have highly unusual, giant-rosette growth forms that appear to be convergent on each other and on those of several independently evolved groups of Asteraceae and other families.

Convergent Evolution of Locomotory Modes in Euarchontoglires

open access: yesFrontiers in Ecology and Evolution, 2020
The research of phenotypic convergence is of increasing importance in adaptive evolution. Locomotory modes play important roles in the adaptive evolution of species in the Euarchontoglires, however, the investigation of convergent evolution of the ...

Coaching by Problem Solving (Convergent Discovery)

open access: yes, 2021
When Coaching by Problem Solving, the coach’s role is to make the decision about the concept to be discovered. The coach designs a problem or question that requires the players to come up with the questions and their own sequence to converge on an answer.

Analogues of some fundamental theorems of summability theory

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
In 1911, Steinhaus presented the following theorem: if A is a regular matrix then there exists a sequence of 0's and 1's which is not A-summable. In 1943, R. C.

A multi-gene phylogeny of Cephalopoda supports convergent morphological evolution in association with multiple habitat shifts in the marine environment

open access: yesBMC Evolutionary Biology, 2012
Background The marine environment is comprised of numerous divergent organisms living under similar selective pressures, often resulting in the evolution of convergent structures such as the fusiform body shape of pelagic squids, fishes, and some marine ...

On some new paranormed sequence spaces of fuzzy numbers defined by Orlicz functions and statistical convergence

open access: yesMathematical Modelling and Analysis, 2006
In this paper we introduce the concept of strongly λ(p) convergence of fuzzy numbers with respect to an Orlicz function and examine some properties of the resulting sequence spaces and λ(p) – statistical convergence.

Double sequence core theorems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
In 1900, Pringsheim gave a definition of the convergence of double sequences. In this paper, that notion is extended by presenting definitions for the limit inferior and limit superior of double sequences.

Statistically unbounded p-convergence in lattice-normed Riesz spaces

open access: yesMiskolc Mathematical Notes, 2023
The statistically unbounded $p$-convergence is an abstraction of the statistical order, unbounded order, and $p$-convergences. We investigate the concept of the statistically unbounded convergence on lattice-normed Riesz spaces with respect to statistical p-decreasing sequences.
