Caustic beams from unusual powers of the spectral phase
(Optical Society of America, 2017-10)
Caustic optical beams arising from a spectral phase whose power lies in an unusual range of values less than two are presented. Unlike what happens for conventional phase powers greater than two, it is feasible to generate ...
MicroRNA expression profiles in the esophagus of children with caustic stenosis: A pathway towards esophageal cancer?
(2020-01-01)
Background: Eighty percent of caustic ingestions occur in children and esophageal neoplasms may develop as a late complication of such injury. The identification of biomarkers is a promising strategy to improve early ...
Dual behavior of caustic optical beams facing obstacles
(American Physical Society, 2017-06)
A full propagation analysis on both fold-type and cusp-type caustic optical beams under various setups of obstructions is theoretically and experimentally performed. It is demonstrated that the self-healing property of ...
Caustics, catastrophes, and symmetries in curved beams
(American Physical Society, 2015-09)
In this paper, a meaningful classification of optical caustic beams in two dimensions is presented. It is demonstrated that the phase symmetry of the beam's angular spectrum governs the optical catastrophe, which describes ...
The use of mitomycin C in caustic esophagitis in rats
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2013-02-01)
PURPOSE: To evaluate the topical effects of mitomycin C (MMC) in rats, with or without esophageal dilation, in different moments after esophageal caustic injury with NaOH10%. METHODS: Forty eight Wistar rats were divided ...
