    Weak-light rogue waves, breathers, and their active control in a cold atomic gas via electromagnetically induced transparency (2016)
    American Physical Society (APS)
    Details
    Publication Date: 2016-06-22
    Description: Author(s): Junyang Liu, Chao Hang, and Guoxiang Huang We propose a scheme to demonstrate the existence of optical Peregrine rogue waves and Akhmediev and Kuznetsov-Ma breathers and realize their active control via electromagnetically induced transparency (EIT). The system we suggest is a cold, Λ -type three-level atomic gas interacting with a probe and … [Phys. Rev. A 93, 063836] Published Tue Jun 21, 2016

    A new technique for deconvolution of data from instruments that make integral measurements, e.g. RIMS on DE-1 (1993)

    Description: A general method for deconvolving an unknown function from integral measurements is described and applied to data from the instrument Retarding Ion Mass Spectrometer (RIMS) aboard the spacecraft Dynamics Explorer 1 (DE-1). The principal features of the method are: (1) it uses objective criteria based upon fundamental statistical principles, i.e. Bayesian statistics; (2) it provides for insertion of prior knowledge in a non-prejudicial, explicit manner through the choice of breakpoints that determine the bicubic spline expansion functions; (3) it prevents random fluctuations from controlling the fit to the data through the use of singular value decomposition and the elimination of small singular values; and (4) it guards agianst the introduction of spurious features into the result by including a penalty function and using the principle of generalized cross validation. Illustrative examples from RIMS data for H(+) and O(+) show that the method provides enhanced accuracy and detail in deconvolving the ion phase space density.
