Chebyshev varieties

Mathematics of Computation
Chebyshev varieties are algebraic varieties parametrized by Chebyshev polynomials or their multivariate generalizations. We determine the dimension, degree, singular locus and defining equations of these varieties. We explain how they play the role of toric varieties in sparse polynomial root finding, when monomials are replaced by Chebyshev ...

The complete mitochondrial genome sequences of Phlebopus portentosus and Leccinum extremiorientale (Boletales; Boletinellaceae: Phlebopus; Leccinum)

Mitochondrial DNA. Part B. Resources
In this study, the complete mitochondrial genomes of Phlebopus portentosus and Leccinum extremiorientale were first sequencedusing the PacBio sequencing platform. We assembled circular mitogenomes of P. portentosus (57,307 bp) and L. extremiorientale (45,

On additive invariants of actions of additive and multiplicative groups

, 2013
Let X be an algebraic variety with an action of either the additive or multiplicative group. We calculate the additive invariants of X in terms of the additive invariants of the fixed point set, using a formula of Białynicki-Birula.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Fine mapping and identification of CaTTG1, a candidate gene that regulates the hypocotyl anthocyanin accumulation in Capsicum annuum

Horticultural Plant Journal
Pepper (Capsicum annuum L.) is a typical self-pollinating crop with obvious heterosis in hybrids. Consequently, the use of morphological markers during the pepper seedling stage is crucial for pepper breeding.

On the lattice of overcommutative varieties of monoids

, 2017
It is unknown so far, whether the lattice of all varieties of monoids satisfies some non-trivial identity. The objective of this note is to give the negative answer to this question. Namely, we prove that any finite lattice is a homomorphic image of some

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Comparison of PhenoCams and drones for lean phenotyping of phenology and senescence of wheat genotypes in variety testing

Plant Phenome Journal
In variety testing and breeding of wheat (Triticum aestivum L.), it is crucial to know the timing of phenological stages and the senescence behavior of genotypes to select for locally adapted varieties.
