Mueller-Polarimetry of Barley Leaves II: Mueller Matrix Decompositions
PhotonicsThis paper highlights the application of decomposition methods in Mueller polarimetry for the discrimination of three groups of barley leaf samples from Hordeum vulgare: Chlorina mutant, Chlorina etiolated mutant and Cesaer varieties in the visible ...

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory
Oikos, EarlyView.Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

On the noise and physical realizability of experimental polarimetric images
EPJ Web of Conferences, 2010 Optical polarimetric images are usually calculated from a set of intensity images recorded with different states of polarization of light [1] . Be cause these latter states are setup dependent, propagation of experimental noise to polarimetric images ...

People and Nature, EarlyView.Abstract Wild deer populations are increasing across the northern hemisphere, posing challenges to the environment and people. Deer impacts can be managed using lethal and non‐lethal practices, but research suggests lethal control receives mixed support.

Polarization Optics to Differentiate Among Bioaerosols for Lidar Applications
PhotonicsPolarization optics, which characterize the orientation of the electromagnetic field through Stokes vectors formalism, have been effectively used in lidar remote sensing to detect particles that differ in shape, such as mineral dust or pollen.

Exploring Costa Rica's fungal trends: Insights from digitized specimens
PLANTS, PEOPLE, PLANET, EarlyView.Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Packaging Technology and Science, EarlyView.Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...

Radar scene generation for tactical decision aids [PDF]
The Mueller matrix and polarization covariance matrix for polarimetric radar systems was studied. The clutter was modeled by a layer of random permittivity, described by a three-dimensional correlation function, with variance, and horizontal and vertical

SensorsThe Jones matrix and the Mueller matrix of the coherent Rayleigh backscattering (RB) in single-mode fibers (SMFs) have been derived recently. It has been shown that both matrices depict two polarization effects—birefringence and polarization-dependent ...
