An analytical model for skylight polarization pattern with multiple scattering

Acta Physica Sinica, 2014
To solve the issues in the modeling of skylight polarization, we build a new analytical model of skylight polarization patterns, which is based on the classic Rayleigh scattering and takes into consideration the multiple scattering properties of atmospheric particles, especially the aerosol. In this paper, we first build the model by the combination of

Feasibility of sun and magnetic compass mechanisms in avian long-distance migration

Movement Ecology, 2018
Birds use different compass mechanisms based on celestial (stars, sun, skylight polarization pattern) and geomagnetic cues for orientation. Yet, much remains to be understood how birds actually use these compass mechanisms on their long-distance ...

Large Scale Homing in Honeybees [PDF]

, 2015
Honeybee foragers frequently fly several kilometres to and from vital resources, and communicate those locations to their nest mates by a symbolic dance language.

Mechanisms of Body Alignment in a Diurnal Songbird Migrant

Ethology, EarlyView.
The graphical abstract illustrates the body alignment mechanism of a diurnal songbird migrant, the dunnock (Prunella modularis). Dunnocks consistently expressed an angular body alignment, with inter‐individual variation at the level of the population.

Skylight polarization patterns under urban obscurations and a navigation method adapted to urban environments

Optics Express, 2021
Owing to preferable anti-interference and anti-cumulative-error capabilities, polarized skylight navigation technology has been developed. However, in urban environments with extensive demand, the sky is usually partially obscured by buildings and trees. Urban landscape obscurations with polarization patterns that have not been sufficiently studied can

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

The Sensory Ecology of Tsetse Flies: Neuroscience Perspectives on a Disease Vector

European Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Tsetse flies (Glossina sp.) are important disease vectors that feed on vertebrate blood. Host‐seeking depends on a combination of sensory systems, from long‐range senses like olfaction and vision, to shorter‐range senses such as audition, mechanosensation, thermosensation and taste.

Compass Cells in the Brain of an Insect Are Sensitive to Novel Events in the Visual World.

PLoS ONE, 2015
The central complex of the insect brain comprises a group of neuropils involved in spatial orientation and memory. In fruit flies it mediates place learning based on visual landmarks and houses neurons that encode the orientation for goal-directed ...

Polarization Navigation Simulation System and Skylight Compass Method Design Based upon Moment of Inertia

, 2020
Unpolarized sunlight becomes polarized by atmospheric scattering and produces a skylight polarization pattern in the sky, which is detected for navigation by several species of insects. Inspired by these insects, a growing number of research studies have

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, Volume 37, Issue 48, December 3, 2025.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG
