An investigation of the Eigenvalue Calibration Method (ECM) using GASP for non-imaging and imaging detectors [PDF]
Polarised light from astronomical targets can yield a wealth of information about their source radiation mechanisms, and about the geometry of the scattered light regions.

Polarization singularities in the clear sky [PDF]
Ideas from singularity theory provide a simple account of the pattern of polarization directions in daylight. The singularities (two near the Sun and two near the anti-Sun) are points in the sky where the polarization line pattern has index +1/2 and the ...

The central complex is an assemblage of highly interconnected neuropils spanning the midline of the insect brain. In the cockroach, five types of pontine neurons and 18 types of columnar neurons interconnect its subcompartments in a topographic manner and provide outputs to other areas of the brain. The data point to a key role of the cockroach central

Celestial polarization patterns sufficient for Viking navigation with the naked eye: detectability of Haidinger's brushes on the sky versus meteorological conditions [PDF]
If a human looks at the clear blue sky from which light with high enough degree of polarization d originates, an 8-shaped bowtie-like figure, the yellow Haidinger's brush can be perceived, the long axis of which points towards the sun.

An analytical model for the celestial distribution of polarized light, accounting for polarization singularities, wavelength and atmospheric turbidity [PDF]
We present a computationally inexpensive analytical model for simulating celestial polarization patterns in variable conditions. We combine both the singularity theory of Dennis and Berry and the intensity model of Perez such that our single model ...

The omnidirectional antireflective properties of 12 different nano‐, micro‐, and bio‐inspired textures on solar glasses are compared, and critical texture parameters are identified. Based on the experimental reflectance data, the energy yield of bifacial solar modules with textured glasses is calculated.

Exploration of a Polarized Surface Bidirectional Reflectance Model Using the Ground-Based Multiangle Spectropolarimetric Imager [PDF]
Accurate characterization of surface reflection is essential for retrieval of aerosols using downward-looking remote sensors. In this paper, observations from the Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI) are used to evaluate a ...

Left panel: We measured immediate‐early gene activation in Cluster N of white‐throated sparrows (Zonotrichia albicollis) in three conditions: nighttime migratory restless, daytime and nighttime resting. Birds in the nighttime migratory restlessness group had significantly greater numbers of ZENK‐labelled cells in Cluster N compared to both the daytime ...

Determination of biogeochemical properties of marine particles using above water measurements of the degree of polarization at the Brewster angle [PDF]
Retrieval of biogeochemical parameters from remotely sensed data in optically complex waters such as those found in coastal zones is a challenging task due to the effects of various water constituents (biogenic, nonalgal and inorganic particles ...
