Macrophage polarization refers to how macrophages have been activated at a given point in space and time. Polarization is not fixed, as macrophages are sufficiently plastic to integrate multiple signals, such as those from microbes, damaged tissues, and the normal tissue environment.

Journal of Mathematical Psychology, 2001 In joint decision making, similarly minded people may take opposite positions. Consider the example of a marriage in which one spouse gives generously to charity while the other donates nothing. Such "polarization" may misrepresent what is, in actuality, a small discrepancy in preferences.

Breaking the limitation of polarization multiplexing in optical metasurfaces with engineered noise
Science, 2023Noise is usually undesired yet inevitable in science and engineering. However, by introducing the engineered noise to the precise solution of Jones matrix elements, we break the fundamental limit of polarization multiplexing capacity of metasurfaces that

How Polarization Begets Polarization
2023Abstract Extreme polarization in American politics—and especially in the US Congress—is perhaps the most confounding political phenomenon of our time. This book connects polarization in Congress and polarization in the electorate within an ever-intensifying feedback loop.

Control of valley polarization in monolayer MoS2 by optical helicity.
Nature Nanotechnology, 2012Electronic and spintronic devices rely on the fact that free charge carriers in solids carry electric charge and spin. There are, however, other properties of charge carriers that might be exploited in new families of devices. In particular, if there are

Nonorthogonal polarizers: a polar analysis
Optics Letters, 2014An analysis of the operators of some widespread nonorthogonal polarizers is performed on the basis of the polar factorization theorem, in pure operatorial (nonmatrix) Dirac algebraic language. The role of the unitary polar component as a converter of the two sets of singular eigenvectors of the operator, one in the other, is emphasized in each case ...

Nature, 1930THE name of Debye is associated with many new and important theories in physics, but none of his theories has more successfully suggested, directed, or stimulated experiment, than his theory of dielectrics. Since Debye's first paper on this subject in 1912, so many advances have been made, and so many new facts established, that an authoritative ...

Metasurfaces are planar structures that locally modify the polarization, phase and amplitude of light in reflection or transmission, thus enabling lithographically patterned flat optical components with functionalities controlled by design.

Acupuncture in Medicine, 2004
Musculoskeletal disorders are common in people who undertake adventure travel to the Antarctic, and in those who support them, because of the hard physical demands and lack of rest. This paper describes the successful use of acupuncture as first line treatment for ten patients in these circumstances, and comments on its advantages, particularly in its
