Depolarization and hyperpolarization of neuronal membrane potentials (in neuroscience).
Over a long-distance system, these drifts accumulate progressively without limit, resulting in rapid and erratic rotation of the polarized light's Jones vector over the entire Poincaré sphere.

In 1979, Charles Lord, Lee Ross and Mark Lepper carried out important research on attitude polarization.
He also invented the Pfund telescope, which is a method for achieving a fixed telescope focal point regardless of where the telescope line of sight is positioned, and the Pfund sky compass, which arose from Pfund's studies of the polarization of scattered light from the sky in 1944, and which greatly helped transpolar flights by allowing the determination of the Sun's direction in twilight.
Alternatively, polarization can be represented as a point on the surface of the Poincaré sphere, with as the longitude and , where , as the latitude.
In the Italian PVLAS experiment polarized light propagates through the magnetic field of a 5 T dipole magnet, searching for a small anomalous rotation of the direction of polarization.
In 2007, Baron Services and L-3 Communications were selected to upgrade 171 U.S. National Weather Service, Department of Defense and Federal Aviation Administration NEXRAD radars to dual-polarization capability.
He was one of the first to recognize the importance of exchange, polarization, multiple scattering, and of the energy dependence of inelastic scattering of very slow electrons in LEED studies of surfaces, and he took them into account theoretically.
Russian mathematician Victor Veselago predicted that a material with simultaneously negative electric and magnetic polarization responses would yield a negative refractive index (an isotropic refractive index of −1), a ‘left-handed’ medium in which light propagates with opposite phase and energy velocities.
The League of Nations Mandate of 1916 appointed Belgium to govern Rwanda after Germany's defeat in World War I; Philip Gourevitch claims that “the terms Hutu and Tutsi had become clearly defined opposing “ethnic” identities, and the Belgians made this polarization the cornerstone of their colonial policy.
iZ3D, Inc., was an American company that developed and sold software which enabled the usage of many different 3D techniques on NVidia and ATI graphic cards, and also sold stereoscopic monitors based on polarization technology.
It was charted by the British Graham Land Expedition under John Rymill, 1934–37, and was named by the UK Antarctic Place-Names Committee in 1960 for French physicist Étienne-Louis Malus, who discovered the polarization of light by reflection, a fact subsequently used in the design of snow goggles.
The signal was at a relatively low power (100w vertical polarization, 100w horizontal polarization) and was broadcast from a transmitter at a site owned by Yorkshire Electricity Distribution PLC (YEDL) at Ainley Top, near the M62.
Polarization controllers with tracking speeds of up to 100 krad/s on the Poincaré sphere are commercially available (see external link at the bottom).
Polarization scramblers usually vary the normalized Stokes vector of the polarization state over the entire Poincaré sphere.
Polarization spectroscopy comprises a set of spectroscopic techniques based on polarization properties of light (not necessarily visible one; UV, X-ray, infrared, or in any other frequency range of the electromagnetic radiation).
At IBC 2011 in Amsterdam RAI several companies, including Sony, Panasonic, JVC & others highlighted their upcoming 3D stereoscopic product portfolios for both the professional and consumer markets to use the same polarization technique as RealD 3D Cinema uses for stereoscopy.
If the polarization of any of the cells in the arrangement shown in figure 4 were to be changed (by a "driver cell"), the rest of the cells would immediately synchronize to the new polarization due to Coulombic interactions between them.
In the season 2 episode "The Panty Piñata Polarization" of The Big Bang Theory, the dictionary is being used during a game of Klingon Boggle.
Members of Roads to You are selected based on their musical merit and leadership potential, as the project seeks to demonstrate cooperation and communication between cultures lost in political polarization.
In 1975 Seiler he his doctorate in physics with the dissertation "Modulated dynamic nuclear polarization of the nuclei of smaller gyromagnetic ratios" at the Free University of Berlin and started his teaching profession for higher education (mathematics and physics) in the following year.
Director of the Yerkes Observatory for many years, while there he designed and built a rotatable telescope for polarization studies and developed photometric instrumentation.
Wannier functions have recently found application in describing the polarization in crystals, for example, ferroelectrics.
He was the first to observe the slight polarization dependence of the human eye, observed via the phenomenon now known as Haidinger's brush.
In a paper published in 1963, he showed that C. G. Darwin's formula for the secondary extinction correction contained an error in the treatment of the polarization of the X-ray beams.
