Spiral patterns, spiral breakup, and zigzag spirals in an optical device
Physical Review E, 2005Above the first lasing threshold the degenerate optical parametric oscillator with saturable absorber displays successive Hopf and Turing instabilities. Various spiral patterns and defect turbulent patterns are numerically observed on the light intensity profiles.

Observing the "Spiral" in the Spiral of Silence
International Journal of Public Opinion Research, 2014Time is of the utmost importance when designing studies to test the spiral of silence theory. The theory posits that individuals who feel they are in the majority become more dominant and louder over time, while the minority camp becomes increasingly silent. However, few studies have tested the dynamic nature of the theory.

We present a new topology for high-speed ring networks: the spiral ring. We also describe a MAC-level protocol, called Distributed Spiral Multiple Access (DSMA), suitable for the spiral ring topology. The DSMA protocol is based on token passing and gives a fair and efficient network behaviour regardless of the transmission rate and network size.

We present a surprising modification of optical interferometry. A so-called spiral phase element in the beam path of a standard microscope results in an interferogram of phase samples, for which the interference fringes have the shape of spirals instead of closed contour lines as in traditional interferograms.

Spiral growth and spiral structure I. Spiral growth in sporangiophores of phycomyces
Biochimica et Biophysica Acta, 1948Abstract An explanation is suggested of spiral growth in sporangiophores of Phycomyces in terms of wall structure. It is pointed out that the growth of the cell resembles the extension of a rather flat spiral spring loaded axially at one end. Like the cell, the spring rotates as it extends.

Dynamin is an important component of membrane recycling at the plasma membrane and, potentially, within the cell. The role of dynamin in clathrin-mediated endocytosis has been based on numerous endocytosis assays, as well as on the discovery and gross characterization of the assembled spiral structure of dynamin.
