doctors and clients sometimes experience interactive clashes during hospital meetings in south-western nigerian hospitals because of their divergent culture-constrained orientation to politeness cues. the goal of this paper is to unpack the discursive elements that characterize interactive confluence and divergence in selected consultative encounters in the hospitals. the findings indicate that...

In this paper, we define and obtain several properties of the (adjacency) energy a hypergraph. particular, bounds for are obtained as functions structural spectral parameters, such Zagreb index radius. We also study how hypergraph varies when vertex/edge is removed or an edge divided. addition, solve extremal problem class hyperstars, show that never odd number.

Several researchers have recently explored various graph parameters that can or cannot be characterized by the spectrum of a matrix associated with graph. In this paper, we show several NP-hard zero forcing numbers are not spectra types matrices particular, consider standard forcing, positive semidefinite and skew provide constructions infinite families pairs cospectral graphs, which different ...

Let G be a simple, connected graph and let A(G) the adjacency matrix of G. If D(G) is diagonal vertex degrees G, then for every real $$\alpha \in [0,1]$$ , $$A_{\alpha }(G)$$ defined as }(G) = \alpha + (1- ) A(G).$$ The eigenvalues form }$$ -spectrum $$G_1 {\dot{\vee }} G_2$$ {\underline{\vee \langle \text {v} \rangle {e} denote subdivision-vertex join, subdivision-edge R-vertex join R-edge two...
