The application of optical absorption spectra in prognostic prediction has hardly been investigated. We developed and evaluated a novel two dimensional absorption spectrum measurement system (TDAS) for use in early diagnosis, evaluating response to chemoradiation, and making prognostic prediction. The absorption spectra of 120 sets of normal and tumor tissues from esophageal cancer patients wer...
In mammals, photoreception is restricted to cones, rods and a subset of retinal ganglion cells. By contrast, non-mammalian vertebrates possess many extraocular photoreceptors but in many cases the role of these photoreceptors and their underlying photopigments is unknown. In birds, deep brain photoreceptors have been shown to sense photic changes in daylength (photoperiod) and mediate seasonal ...
This paper is aimed at giving structural designers guidance on how to make use of elastic site-specific response spectra for the dynamic modal analysis a structure in support its design. The pushover an RC building forming part non-linear static procedure (that can be used predict seismic demand without relying code-stipulated default R factor) also presented. Seismic structures based help achi...
This paper is aimed at serving the needs of structural engineering researchers who are seeking accelerograms that realistically represent time histories earthquake ground in support their own investigations. Every record identified with a specific scenario defined by magnitude–distance combination and site conditions; intensity presented records consistent ultimate limit state design requiremen...
While 540 nanometers is the most effective wavelength in provoking development, larvae are far more responsive to 540-nanometer light if it is provided immediately preceding rather than followng a white-light photophase which otherwise serves to maintain diapause. This difference in sensitivity is probably due to bleaching and implies that the larvae experience an asymmetric day.
