Abstract In Directed Feedback Arc Set ( DFAS ) we search for a set of at most k arcs which intersect every cycle in the input digraph. It is well-known open problem parameterized complexity to decide if admits kernel polynomial size. We consider $$\mathcal {C}$$ C - Deletion ADS ), variant where want remove f...

morning glory syndrome (mgs) is a rare congenital optic disc anomaly characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. the main ophthalomoscopic feature of the mgs is enlarged optic disc with a funnel shaped scleral defect; elevated peripapillary chorioretinal pigmentation; and pale fluffy tissue of glial hyperplasia overlying the optic d...

The skyrmion-substrate interaction is an important issue to consider when studying particle-like skyrmions in nanostructures, which may strongly affect the skyrmion dynamics and lead complex dynamic phenomena. Here, we report current-driven behaviors of interacting with funnel obstacle a ferromagnetic layer. We computationally demonstrate that enhanced perpendicular magnetic anisotropy can be u...
