Genome-wide evidence for speciation with gene flow in Heliconius butterflies

open access: yesGenome Research, 2013
Most speciation events probably occur gradually, without complete and immediate reproductive isolation, but the full extent of gene flow between diverging species has rarely been characterized on a genome-wide scale.

Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Butterflies (Lepidoptera: Papilionoidea) of Mount Sago, West Sumatra: Diversity and Flower Preference

open access: yesHayati Journal of Biosciences, 2016
Diversity of butterfly depends on the availability of food plant and habitat quality. The aims of this study were to assess diversity and flower preference of butterflies in Mount Sago, West Sumatra, Indonesia.

Spatial Distribution of Pollinating Butterflies in Yunnan Province, Southwest China with Resource Conservation Implications

open access: yesInsects, 2020
Pollinating butterflies are an important asset to agriculture, which still depends on wild resources. Yunnan Province in Southwest China is a region with typical montane agriculture, but this resource is poorly investigated. From literature reference and

Butterflies and Rebirth

open access: yes, 2017
During the Renaissance, collectors saw Morpho butterflies as beautiful, elegant, and rare creatures. Their exotic origin and sophistication made these fascinating creatures the subjects of scientific observation, decoration, and symbolism. Butterflies of

Further Results of the Cryptographic Properties on the Butterfly Structures

open access: yes, 2016
Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equal to 4 and algebraic degree is also very high when exponent $e=3$.

Butterflies I: morphisms of 2-group stacks [PDF]

open access: yes, 2008
Weak morphisms of non-abelian complexes of length 2, or crossed modules, are morphisms of the associated 2-group stacks, or gr-stacks. We present a full description of the weak morphisms in terms of diagrams we call butterflies.

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.
