Insect brain plasticity: effects of olfactory input on neuropil size [PDF]

open access: yesRoyal Society Open Science, 2019
Insect brains are known to express a high degree of experience-dependent structural plasticity. One brain structure in particular, the mushroom body (MB), has been attended to in numerous studies as it is implicated in complex cognitive processes such as

First record of Lestranicus transpectus (Moore, 1879) and Graphium macareus (Godart, 1819) (Insecta: Lepidoptera: Papilionoidea) in Bangladesh

open access: yesRevista Chilena de Entomología, 2021
Lestranicus transpectus and Graphium macareus are new observations of butterfly fauna to Bangladesh for the first time from Baro Chara (22.50° N, 92.18° E, 9 m), Rangamati district of Chittagong division.

Vertex Priority Based Butterfly Counting for Large-scale Bipartite Networks [PDF]

open access: yesProceedings of the VLDB Endowment, 2018
Bipartite networks are of great importance in many real-world applications. In bipartite networks, butterfly (i.e., a complete 2 x 2 biclique) is the smallest non-trivial cohesive structure and plays a key role.

Not only the butterflies: managing ants on road verges to benefit Phengaris (Maculinea) butterflies [PDF]

open access: yes, 2010
Obligate myrmecophilic butterfly species, such as Phengaris (Maculinea) teleius and P. nausithous, have narrow habitat requirements. Living as a caterpillar in the nests of the ant species Myrmica scabrinodis and M.

Observation of Hofstadter butterfly and topological edge states in reconfigurable quasi-periodic acoustic crystals

open access: yesCommunications Physics, 2019
The emergence of a fractal energy spectrum is the quintessence of the interplay between two periodic parameters with incommensurate length scales. crystals can emulate such interplay and also exhibit a topological bulk-boundary correspondence, enabled by

Criticality in Third Order Lovelock Gravity and the Butterfly effect

open access: yes, 2017
We study third order Lovelock Gravity in $ D=7 $ at the critical point which three (A)dS vacua degenerate into one. We see there is not propagating graviton at the critical point. And also we compute the butterfly velocity for this theory at the critical

Supersaturation and stability for forbidden subposet problems [PDF]

open access: yes, 2015
We address a supersaturation problem in the context of forbidden subposets. A family $\mathcal{F}$ of sets is said to contain the poset $P$ if there is an injection $i:P \rightarrow \mathcal{F}$ such that $p \le_P q$ implies $i(p) \subset i (q)$.

Butterfly Velocities for Holographic Theories of General Spacetimes

open access: yes, 2017
The butterfly velocity characterizes the spread of correlations in a quantum system. Recent work has provided a method of calculating the butterfly velocity of a class of boundary operators using holographic duality.

The genome sequence of the Welsh wave moth, Venusia cambrica Curtis, 1839 [version 1; peer review: 1 approved, 2 approved with reservations]

open access: yesWellcome Open Research
We present a genome assembly from an individual male Venusia cambrica (the Welsh Wave; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence spans 470.40 megabases.
