Butterfly Factorization [PDF]

open access: yesMultiscale Modeling & Simulation, 2015
The paper introduces the butterfly factorization as a data-sparse approximation for the matrices that satisfy a complementary low-rank property. The factorization can be constructed efficiently if either fast algorithms for applying the matrix and its adjoint are available or the entries of the matrix can be sampled individually.

Revisiting the flight dynamics of take-off of a butterfly: experiments and CFD simulations for a cabbage white butterfly

open access: yesBiology Open, 2022
We conducted measurements of the taking-off motion of a butterfly (Pieris rapae) and numerical simulations using a computational model reflecting its motion.

Lieb-Robinson and the butterfly effect [PDF]

open access: yes, 2016
As experiments are increasingly able to probe the quantum dynamics of systems with many degrees of freedom, it is interesting to probe fundamental bounds on the dynamics of quantum information.

An observation on the fruit feeding behavior of butterflies in some areas of Bangladesh

open access: yesJournal of Threatened Taxa, 2016
Very little information has been found about the behavior of fruit feeding butterflies in Bangladesh. So this was an attempt to know about the fruit feeding behavior of butterflies from different areas of Bangladesh.

Butterfly diversity (Lepidoptera: Rhophalocera) associated with nectar feeding on Ziziphus mauritiana Lamarck (Rosales: Rhamnaceae) flowers in Chuadanga, Bangladesh

open access: yesJournal of Threatened Taxa, 2017
A study was conducted during the flowering season of Ziziphus mauritiana from September 2015 to October 2015 in Belgachi Railgate Para, Chuadanga, Bangladesh.

Applying computer vision to digitised natural history collections for climate change research: Temperature‐size responses in British butterflies

open access: yesMethods in Ecology and Evolution, 2023
Natural history collections are invaluable resources for understanding biotic response to global change. Museums around the world are currently imaging specimens, capturing specimen data and making them freely available online.

A List of the Butterflies (Lepidoptera: Papilionoidea) of the La Rue-Pine Hills Ecological Area [PDF]

open access: yes, 2017
A survey of the adult butterfly fauna of the La Rue-Pine Hills Ecological Area, Union County, Illinois, was conducted from March through July in 1979, and March through November in 1980.

Evaluating costs of heavy metal tolerance in a widely distributed, invasive butterfly

open access: yesEvolutionary Applications, 2021
Organismal tolerance to environmental pollution is thought to be constrained by fitness costs, where variants with higher survival in polluted environments have lower performance in nonpolluted environments.
