Journal of Combinatorial Theory, Series A, 2023 Extending the notion of sunflowers, we call a family of at least two sets an \emph{odd-sunflower} if every element of the underlying set is contained in an odd number of sets or in none of them. It follows from the Erd\H os--Szemer\'edi conjecture, recently proved by %Alweiss, Lovett, Wu, and Zhang, Naslund and Sawin, that there is a constant $\mu < ...

, 2023 We study sunflowers within the context of finitely generated substructures of ultrahomogeneous structures. In particular, we look at bounds on how large a set system is needed to guarantee the existence of sunflowers of a given size. We show that if we fix the size of the sunflower, the function which takes the size of the substructures in our set ...

Combinatorics, Probability and Computing, 2018 A sunflower is a collection of distinct sets such that the intersection of any two of them is the same as the common intersectionCof all of them, and |C| is smaller than each of the sets. A longstanding conjecture due to Erdős and Szemerédi (solved recently in [7, 9]; see also [22]) was that the maximum size of a family of subsets of [n] that contains ...

Potential of a sunflower seed by-product as animal fat replacer in healthier Frankfurters [PDF]
, 2020 Upcycled defatted sunflower seed flour (SUN), a by-product obtained from sunflower oil extraction, was used as an animal fat replacer to develop healthier frankfurters.

Evaluation of Argentine wild sunflower biotypes for drought stress during reproductive stage [PDF]
, 2012 As in several regions where sunflower production has moved to areas with limiting water availability, the search for water-stress tolerant genotypes has been intensified. Helianthus annuus ssp. annuus L.

Sterol content in sunflower seeds (Helianthus annuus L.) as affected by genotypes and environmental conditions [PDF]
, 2010 Phytosterols play essential roles in many plant cell mechanisms. They are of industrial interest since, as part of the diet, they can reduce Low Density Lipoprotein cholesterol.

Sunflowers and robust sunflowers from randomness extractors
, 2022 Summary: The Erdős-Rado Sunflower Theorem [\textit{P. Erdős} and \textit{R. Rado}, J. Lond. Math. Soc. 35, 85--90 (1960; Zbl 0103.27901)] is a fundamental result in combinatorics, and the corresponding Sunflower Conjecture is a central open problem. Motivated by applications in complexity theory, \textit{B. Rossman} [SIAM J. Comput. 43, No. 1, 256--279

Sterol concentration and distribution in sunflower seeds (Helianthus annuus L.) during seed development [PDF]
, 2010 Sunflower seeds are currently used for edible oil production. Among oil minor compounds, phytosterols are of special interest due to their cholesterol reducing properties.
