A signed graph is a graph where the edges are assigned either positive ornegative signs. Net degree of a signed graph is the dierence between the number ofpositive and negative edges incident with a vertex. It is said to be net-regular if all itsvertices have the same net-degree. Laplacian energy of a signed graph is defined asε(L(Σ)) =|γ_1-(2m)/n|+...+|γ_n-(2m)/n| where γ_1,...,γ_n are the ei...

It is shown that the conclusions reached by Tereno are completely faulty We have recently shown that the Kruskal derivative assumes a form [1] du dv → f(r, t, dr/dt) ±f(r, t, dr/dt) (1) because u → ±v as r → 2M . Although this limit attains a value of ±1 irrespective of f → 0,∞, or anything, Tereno [2] refuses to accept this. Although, we have already pointed out that one should work out the li...

Beta 2-Microglobulin-deficient (beta 2m -/-) mice are reported to lack cell surface expression of major histocompatibility complex (MHC) class I molecules, CD8+ T cells, and the ability to mount MHC class I-specific T cell responses. We have observed that beta 2m -/- mice possess CD8+ T cells that can be induced to perform strong allospecific cytotoxic responses against nonself-MHC class I by i...
