Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

open access: yesAdvanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.

Occurrence data of southern butterflies in South Korea [PDF]

open access: yesGeo Data, 2020
Background In Northern hemisphere, climate change has shifted the habitats of many species including butterflies into the northern regions. Many researchers in Europe and North America have reported this type of northward shift of butterflies.

Causal Analysis of a Migration of the Snout Butterfly, Libytheana bachmanii Iarvata (Strecker) (Libytheidae) [PDF]

open access: yes, 1983
Observation of a massive migration of the snout butterfly, Libytheana bachmanii larvata (Strecker), in central Texas in 1971 is described. An association of peak migration periods and periodic precipitation episodes is believed to be causal in nature ...

Complex Oxide‐metal Hybrid Metamaterials with Integrated Magnetic and Plasmonic Non‐noble Metal Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new alloy‐oxide vertically aligned nanocomposite (VAN) thin film with two immiscible non‐noble metal elements of Co and Cu embedded in BaTiO3 (BTO) matrix is designed and fabricated, which presents interesting magnetic, ferroelectric, and optical properties.

A Mistaken Butterfly [PDF]

open access: yesNature, 1918
IN NATURE of September 5 last an Australian correspondent notes the attraction of the blue knob of a hatpin for a butterfly. When playing golf in Gulmarg (Kashmir) this summer I was frequently put off by a large butterfly settling on the ball just as I was making a stroke. I make a point of keeping my ball white and clean, and the butterflies evidently

FLEET: Butterfly Estimation from a Bipartite Graph Stream

open access: yes, 2019
We consider space-efficient single-pass estimation of the number of butterflies, a fundamental bipartite graph motif, from a massive bipartite graph stream where each edge represents a connection between entities in two different partitions. We present a

Puddling by Female Florida Tiger Swallowtail Butterflies, \u3ci\u3ePapillo Glaucus Australis\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2017
(excerpt) Many species from all families of Rhopaloccra have been reported to drink water (Norris 1936). Bates (1863) noted that, in the Amazon, 80 species from 22 genera flocked about the damp edges of water and, with very few exceptions, all of these ...

The Rooster and the Butterflies [PDF]

open access: yes, 2013
This paper describes a machine-checked proof of the Jordan- Hölder theorem for finite groups. This purpose of this description is to discuss the representation of the elementary concepts of finite group theory inside type theory. The design choices underlying these representations were crucial to the successful formalization of a complete proof of the ...
