Observational evidence of third dredge-up occurrence in S-type stars with initial masses around 1 Msun

, 2019
Context- S stars are late-type giants with spectra showing characteristic molecular bands of ZrO in addition to the TiO bands typical of M stars. Their overabundance pattern shows the signature of s-process nucleosynthesis.

Families of Quintic Calabi-Yau 3-Folds with Discrete Symmetries [PDF]

, 2007
At special loci in their moduli spaces, Calabi-Yau manifolds are endowed with discrete symmetries. Over the years, such spaces have been intensely studied and have found a variety of important applications.

MADS-Box Gene Classification in Angiosperms by Clustering and Machine Learning Approaches

Frontiers in Genetics, 2019
The MADS-box gene family is an important transcription factor family involved in floral organogenesis. The previously proposed ABCDE model suggests that different floral organ identities are controlled by various combinations of classes of MADS-box genes.

Floral organ MADS-box genes in Cercidiphyllum japonicum (Cercidiphyllaceae): Implications for systematic evolution and bracts definition. [PDF]

PLoS ONE, 2017
The dioecious relic Cercidiphyllum japonicum is one of two species of the sole genus Cercidiphyllum, with a tight inflorescence lacking an apparent perianth structure.

Genome-wide analysis of the MADS-box gene family in Lonicera japonica and a proposed floral organ identity model

BMC Genomics, 2023
Background Lonicera japonica Thunb. is widely used in traditional Chinese medicine. Medicinal L. japonica mainly consists of dried flower buds and partially opened flowers, thus flowers are an important quality indicator.

Expression and Functional Analyses of Nymphaea caerulea MADS-Box Genes Contribute to Clarify the Complex Flower Patterning of Water Lilies

Frontiers in Plant Science, 2021
Nymphaeaceae are early diverging angiosperms with large flowers characterized by showy petals and stamens not clearly whorled but presenting a gradual morphological transition from the outer elements to the inner stamens.

ABCD transfer matrix model of Gaussian beam propagation in Fabry-Perot etalons

Optics Express, 2022
A numerical model of Gaussian beam propagation in planar Fabry-Perot (FP) etalons is presented. The model is based on the ABCD transfer matrix method. This method is easy to use and interpret, and readily connects models of lenses, mirrors, fibres and other optics to aid simulating complex multi-component etalon systems.

Unveiling the health‐promoting potential of Sudanese sorghum landraces: A legacy rooted in Eastern Sudan, Kassala, and the Red Sea States

PLANTS, PEOPLE, PLANET, EarlyView.
Sorghum is a staple food for hundreds of millions of people in dry regions worldwide, and improving its nutritional quality is vital for global food and health security under climate change. In this study, we evaluated traditional Sudanese sorghum varieties grown in eastern deltas to better understand their natural health‐promoting properties. We found
