Given a knot in the 3-sphere, non-orientable 4-genus or 4-dimensional crosscap number of is minimal first Betti surfaces, smoothly and properly embedded 4-ball, with boundary knot. In this paper, we calculate knots crossing 10.

Objective: 10-Year survival (10YS) after radical surgery for non-small cell lung cancer (LC) pa­tients (LCP) (T1-4N0-2M0) was analyzed. Methods: We analyzed data of 768 consecutive LCP (age=57.6±8.3 years; tumor size=4.1±2.4 cm) radically operated (R0) and monitored in 1985-2021 (m=660, f=108; upper lobectomies=277, lower lobectomies=177, middle lobectomies=18, bilobectomies=42, pneumonectomies...
