Identities of Degenerate Poly-Changhee Polynomials Arising from λ-Sheffer Sequences
Journal of Mathematics, 2022 In the 1970s, Gian-Carlo Rota constructed the umbral calculus for investigating the properties of special functions, and by Kim-Kim, umbral calculus is generalized called λ-umbral calculus.

Spatial Distribution of Origin of Umbral Waves in a Sunspot Umbra
, 2020 Umbral flashes (UFs) are emissions in the core of chromospheric lines caused by upward propagating waves steepening into shocks. UFs are followed by an expanding blue shifted umbral wave (UW) and red-shifted plasma returning to the initial state. Here we

Publications de l'Institut Mathematique, 2016 A general linear interpolation problem is posed and solved. This problem is called umbral interpolation problem because its solution can be expressed by a basis of Sheffer polynomials. The truncation error and its bounds are considered. Some examples are discussed, in particular generalizations of Abel-Gontscharoff and central interpolation

Synchronicity in Post‐Jungian Astrology: A Cosmological Quest
Journal of Analytical Psychology, Volume 70, Issue 5, Page 808-824, November 2025.Abstract Jung promoted the idea of synchronicity in 1928, in the context of discussing the Chinese way of thinking. From 1928 to 1951, Jung’s informal formulations led to more than one understanding of synchronicity. He even tried to apply synchronicity to an astrological experiment.

Downflows in sunspot umbral dots
, 2010 We study the velocity field of umbral dots at a resolution of 0.14". Our analysis is based on full Stokes spectropolarimetric measurements of a pore taken with the CRISP instrument at the Swedish 1-m Solar Telescope.

, 2012 Durante el transcurso de la investigación experimente con fenómenos del comportamiento físico de la materia y las cualidades ópticas que permiten ver esos fenómenos; la permanencia y la impermanencia son los vectores trascendentales en la exploración. Sobre el comportamiento de la luz (la que nos permite ver) he encontrado una paradoja: a la vez que ...

Review of Policy Research, Volume 42, Issue 6, Page 1509-1524, November 2025.ABSTRACT This paper provides a retrospective on California's oversight of 1,3‐dichloropropene (1,3‐D). It utilizes archival documents, including internal memos, emails, and risk assessments, to demonstrate how the state's Department of Pesticide Regulation consistently expanded allowable 1,3‐D use while presenting each policy change as scientifically ...
