MathematicsIn this paper, we study (i)-curves with i∈{−1,0,1} in the blown-up projective space Pr in general points. The notion of (−1)-curves was analyzed in the early days of mirror symmetry by Kontsevich, with the motivation of counting curves on a Calabi–Yau ...

K3 surfaces, rational curves, and rational points
Journal of Number Theory, 2010 10 pages, no figures. An explicit construction of an algebraic point lying on no smooth rational curves has been added to the end, and there have been minor revisions to the rest of the ...

Towards analytic structure of Feynman parameter integrals with rational curves
Journal of High Energy Physics, 2022 We propose a strategy to study the analytic structure of Feynman parameter integrals where singularities of the integrand consist of rational irreducible components.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Some aspects of rational points and rational curves
, 2023 Various methods have been used to construct rational points and rational curves on rationally connected algebraic varieties. We survey recent advances in two of them, the descent and the fibration method, in a number-theoretical context (rational points over number fields) and in an algebro-geometric one (rational curves on real varieties), and discuss

Approximation of conic sections by weighted Lupaş post-quantum Bézier curves
Demonstratio Mathematica, 2022 This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

A Note on the Rational Cuspidal Curves [PDF]
Bulletin of the Polish Academy of Sciences Mathematics, 2014 In this short note we give an elementary combinatorial argument, showing that the Conjecture of J. Fernández de Bobadilla, I. Luengo, A. Melle-Hernández, A. Némethi follows from the results of M. Borodzik and C. Livingston in the case of rational cuspidal curves with two critical points.
