In the simplex method, ( z_j - c_j ) represents the reduced cost of a non-basic variable ( j ). Here, ( z_j ) is the contribution of variable ( j ) to the objective function value based on the current solution, while ( c_j ) is the cost coefficient of that variable. If ( z_j - c_j ) is positive, it indicates that increasing variable ( j ) would not improve the objective function, while a negative value suggests that increasing ( j ) could be beneficial for optimization.
The 1916 Proclamation of the Irish Republic, which was issued during the Easter Rising, was signed by seven leaders of the uprising. These leaders were Patrick Pearse, James Connolly, Thomas J. Clarke, Joseph Plunkett, Seán Mac Diarmada, Éamonn Ceannt, and Thomas Ashe. The proclamation declared the establishment of the Irish Republic and was a pivotal moment in the struggle for Irish independence.

From the 1930s to the present, beginning with neoprene and nylon, the American chemical industry has introduced a cornucopia of polymers to the consumer. Teflon, discovered by Roy Plunkett (1910-1994) at DuPont's Jackson Laboratory in 1938, was an accidental invention-unlike most of the other polymer products. But as Plunkett often told student audiences, his mind was prepared by education and training to recognize novelty. By Bryan Coby
