Polarized object detection in crabs: a two-channel system
(Company of Biologists, 2018-05)
Many animal species take advantage of polarization vision for vital tasks such as orientation, communication and contrast enhancement. Previous studies have suggested that decapod crustaceans use a two-channel polarization ...
Enantioseparation of polar pesticides on chiral capillary columns based on permethyl-β-cyclodextrin in matrices of different polarities
(Elsevier Science, 2018-07)
This work describes the influence of different achiral polymers used to dissolve permethyl-β-cyclodextrin (PM-β-CD) on the gas chromatographic enantioresolution of racemic mixtures of polar pesticides (mecoprop, dichlorprop, ...
Polar decomposition of oblique projections
(Elsevier Science Inc., 2010-10)
The partial isometries and the positive semidefinite operators which appear as factors of polar decompositions of bounded linear idempotent operators in a Hilbert space are characterized.
Dynamic Filtering of Microwave Signals through Brillouin-Based Polarization-Sensitive Balanced Detection
(Institute of Electrical and Electronics Engineers, 2021-03)
A new photonic technique to implement both stopband and passband microwave filters is presented and demonstrated. The principle of operation relies on controlling the state of polarization of the band of interest using ...
Polar caps and auroral zones under idealized axisymmetric magnetic fields
(Elsevier, 2021-05)
The geomagnetic field, modified by the solar wind, determines the shape, area and location of polar caps and auroral zones, among other magnetosphere and upper atmosphere characteristics. Since the field varies greatly ...
Polarity studies of single polyelectrolyte layers in polyelectrolyte multilayers probed by steady state and life time doxorubicin fluorescence
(Elsevier, 2022-02)
Hypothesis: Polarity in polyelectrolyte multilayers (PEMs) may vary from the inner to the top layers of the film as the charge compensation of the layers is more effective inside the PEMs than in outer layers. Doxorubicin ...
Attosecond polarization control in atomic RABBITT-like experiments assisted by a circularly polarized laser
(IOP Publishing, 2017-10)
We study theoretically the single ionization of noble gas atoms by the combined action of an attosecond pulse train with linear polarization and an assistant laser field with circular polarization. We employ a non-perturbative ...
Design of a Multiport Microwave Modulator for Dynamic Polarization Reconfiguration
(Institute of Electrical and Electronics Engineers, 2019-05)
This paper presents a seven-port modulator capable of switching the polarization state of the transmitting signal. Similar to the six-port modulator, the proposed device modulates the carrier signal through the reflection ...
