1. The North Atlantic Oscillation (NAO) exerts considerable control on U.K. weather. This study investigates the impact of the NAO on butterfly abundance and phenology using 34 years of data from the U.K. Butterfly Monitoring Scheme (UKBMS).2. The study uses a multi-species indicator to show that the NAO does not affect overall U.K. butterfly population size. However, the abundance of bivoltine...

B utterfly shaped macular dystrophy was first described by Deutman et al. in 1970. It is characterised by bilateral accumulation of pigmented or yellowish material at the level of the retinal pigment epithelium. Lesions consist of 3–5 ‘‘wings,’’ which resemble the wings of a butterfly. Affected patients present with a subnormal electrooculogram and normal or slightly diminished visual acuity. T...

In the work, we rebuild the masks of well-known interpolatory symmetric subdivision schemes-binary 2n-point interpolatory schemes, the ternary 4-point interpolatory scheme using only the symmetry and the necessary condition for smoothness and the butterfly scheme, and the modified butterfly scheme using the factorization property. 2006 Elsevier Inc.

This paper presents a butterfly physically unclonable function (PUF) implementation in SRAM-based field programmable gate arrays (FPGAs). To avoid output instability, we propose a delay difference test to identify reliable slices (mapped to which butterfly PUF cells are highly reliable) and then PUF reliability is significantly improved by selective mapping PUF cells to reliable slices, which i...

We present a simple model for synthesis of butterfly wing patterns. The model simulates the formation of eyespots as are called the rounded circular arrangements which appear in many butterfly species. We illustrate our results with the examples of Diatheria clymena and Automeris io species.

In this study, we are concerned with non-stationary interpolatory subdivision schemes with refinement rules which may vary from level to level. First, we derive a new class of interpolatory non-stationary subdivision schemes reproducing exponential polynomials. Next, we prove that non-stationary schemes based on the known butterfly-shaped stencils possess the same smoothness as the known Butter...
