The genus of $K_n ,n = 12\left( {2^m } \right)$

The crossing numbers of $K_{n,n}-nK_2$, $K_{n}\times P_2$, $K_{n}\times P_3$ and $K_n\times C_4$

The crossing number of a graph G is the minimum number of pairwise intersections of edges among all drawings of G. In this paper, we study the crossing number of Kn,n − nK2, Kn × P2, Kn × P3 and Kn × C4.

The Bogdanov-Takens bifurcation study of 2m coupled neurons system with 2m+1$2m+1$ delays

In this paper the Bogdanov-Takens (BT) bifurcation of an 2m coupled neurons network model with multiple delays is studied, where one neuron is excitatory and the next is inhibitory. When the origin of the model has a double zero eigenvalue, by using center manifold reduction of delay differential equations (DDEs), the second-order and third-order universal unfoldings of the normal forms are ded...

Who has the “Right” to Use the N-Word? A Survey of Attitudes about the Acceptability of Using the N-Word and its Derivatives

The N-word is the ultimate insult that has tormented generations of African-Americans. Yet over time, N-word derivatives have become popular terms of endearment by the descendants of the very people who once had to endure the N-word. Therein lies the root of an ongoing argument in society today: Who has the ‘right’ to use the N-word and N-word derivatives?  A quota sample (N=347) of undergradua...
