Second integral generalization of the Crocco invariant for 3D flows behind detached bow shock wave [PDF]
Stationary flows of an ideal gas behind the detached bow shock are investigated in the general 3D case. The well-known integral invariant (V.N.Golubkin, G.B.Sizykh, 2019), generalizing the axisymmetric invariant of (L.Crocco, 1937) to asymmetric flows ...

A class of Baker-Akhiezer arrangements [PDF]
We study a class of arrangements of lines with multiplicities on the plane which admit the Chalykh–Veselov Baker–Akhiezer function. These arrangements are obtained by adding multiplicity one lines in an invariant way to any dihedral arrangement with ...

Generation of Novel Traj18-Deficient Mice Lacking Vα14 Natural Killer T Cells with an Undisturbed T Cell Receptor α-Chain Repertoire. [PDF]
Invariant Vα14 natural killer T (NKT) cells, characterized by the expression of a single invariant T cell receptor (TCR) α chain encoded by rearranged Trav11 (Vα14)-Traj18 (Jα18) gene segments in mice, and TRAV10 (Vα24)-TRAJ18 (Jα18) in humans, mediate ...

Centers of cubic differential systems with the line at infinity of maximal multiplicity
We classify all cubic differential systems with a center-focus critical point and the line at infinity of maximal multiplicity. It is proved that the critical point is of the center type if and only if the divergence of the vector field associated to ...

E-strings, F 4, and D 4 triality
We study the E-string theory on ℝ4 × T 2 with Wilson lines. We consider two examples where interesting automorphisms arise. In the first example, the spectrum is invariant under the F 4 Weyl group acting on the Wilson line parameters.

Rationality properties of manifolds containing quasi-lines [PDF]
Let X be a complex, rationally connected, projective manifold. We show that X admits a modification X' that contains a quasi-line, ie a smooth rational curve whose normal bundle is a direct sum of copies of O_{P^1}(1).

Robust Line Feature Matching via Point–Line Invariants and Geometric Constraints
Line feature matching is a crucial aspect of computer vision and image processing tasks, attracting significant research attention. Most line matching algorithms predominantly rely on local feature descriptors or deep learning modules, which often suffer
