  • n. Plural form of sigmoid.


Sorry, no etymologies found.


  • A new model shows how large "S" - shaped structures on the sun called sigmoids emerge from its interior and erupt to create fireballs and flares

    New Scientist - Online News

  • First, we fit sigmoids to the replication fraction of origins from the microarray data and infer that the timing and the variation in timing of origin initiation are correlated.

  • We initially fit the data with individual sigmoids at each origin, in effect giving each origin an independent firing program.

  • Over the years a series of theoretical and numerical models have been proposed to explain the nature of sigmoids but until now there was no explanation on how such complex structures form, erupt and fade away.

  • The new model describes how sigmoids consist of many thin and twisted layers (or ribbons) of strong electric current.

  • When it does, the team hopes other satellite observations could be combined to better measure sigmoids.

  • In the model, sigmoids begin their lives below the visible surface of the sun.

  • Just a handful of sigmoids have been observed by Hinode, and few new ones are expected until the sun emerges from its current lull in activity.

  • The ILD-dependent component here is a difference of sigmoids; selection of different parameters can produce ILD tuning curves that range from sigmoidal to peaked, as is seen in ICcl is mapped to a spiking probability using a threshold-sigmoid nonlinearity, rather than the power-law nonlinearity suggested by Murphy and Miller

  • (t) curves are well described by sigmoids with parameters
