A liquid nitrogen immersion cryostat for optical measurements
liquid nitrogen immersion cryostat optical measurements
2016/5/23
A liquid nitrogen immersion cryostat has been developed for optical measurements. Liquid nitrogen in the sample chamber is kept free of bubbles and schlieren by the use of a cooling jacket of sacrific...
Constructing graphs with no immersion of large complete graphs
Graph immersion minimum degree chromatic number edgeconnectivity Hajos Conjecture Hadwiger Conjecture graph minor
2012/6/29
In 1989, Lescure and Meyniel proved, for $d=5, 6$, that every $d$-chromatic graph contains an immersion of $K_d$, and in 2003 Abu-Khzam and Langston conjectured that this holds for all $d$. In 2010, D...
