Optical probing of pups brain tissue and molecular specific nuclear nano-structural alterations due to fetal alcoholism via dual spectroscopic approach
Prakash Adhikari, Pradeep K. Shukla, Shiva Bhandari +6
Mesoscopic physics-based dual spectroscopic imaging techniques, partial wave spectroscopy (PWS) and inverse participation ratio (IPR), are used to quantify the nano to submicron sc…
Derivation of statistics of real delay time from statistics of imaginary delay time using spectroscopic technique in weakly disordered optical media
Prabhakar Pradhan, Peeyush Sahay, Huda M. Almabadi
Delay time is defined as a time that a wave spent in a scattering medium before it escapes, and this can be derived by the energy derivative of the phase of the scattering wave. Co…
Photonic localization probe of molecular specific intranuclear structural alterations in brain cells due to fetal alcoholism via confocal microscopy
Shiva Bhandari, Pradeep K. Shukla, Peeyush Sahay +4
Molecular specific photonic localization is a sensitive technique to probe the structural alterations or abnormalities in a cell such as abnormalities due to alcohol or other drugs…

Detection of Cancer Stages via Fractal Dimension Analysis of Optical Transmission Imaging of Tissue Micro Arrays (TMA)
Shiva Bhandari, Sri Choudannavar, Ethan Avery +2
Cancer is an epidemic worldwide. At present one in four persons has cancer and this statistic will change to one in a two person in the near future. It is now known that war agains…
Deriving real delay time statistics from the complex delay time statistics in weakly disordered optical media
Prabhakar Pradhan, Peeyush Sahay, Huda M. Almabadi
Considering the complex reflection amplitude R=|R|exp(iθ) of a light wave, real delay time τ_r (i.e., sojourn or Wigner delay time), which is the energy derivative of the real phas…
