The sum-connectivity index R′(G) of a graph G is the sum of the weights (du +dv) − 2 of all edges uv of G, where du and dv are the degrees of the vertices u and v in G. This index was recently introduced in [B. Zhou, N. Trinajstić, On a novel connectivity index, J. Math. Chem. 46(2009), 1252–1270]. In this paper, we give the sharp lower bound of the sum-connectivity index of n-vertex unicyclic ...

Chronic illness in children may negatively affect aspects of health-related quality of life (HRQL). Over many years, camps have been organized to address the physical and psychosocial needs of children with various chronic illnesses, while providing a "normal" as possible camp experience. The aim of this study was to critically review all research examining the effect of camps on HRQL in childr...

Strange and non-strange axial-vector meson radiative decays contribute to photon production in hadron gas. Oneand two-hadron radiative decay modes of b1(1235), a1(1260) andK1(1270) are studied. At 200 MeV temperature and for a narrow range in photon energies they contribute more to the net thermal photon production rate than πρ → πγ, ππ → ργ or ρ → ππγ. They provide significant contribution to ...

In this talk I summarize recent findings made on the description of axial vector mesons as dynamically generated states from the interaction of peseudoscalar mesons and vector mesons, dedicating some attention to the two K1(1270) states. Then I review the generation of open and hidden charm scalar and axial states. Finally, I present recent results showing that the low lying 1/2 baryon resonanc...

In this work, we perform a combined analysis to the measured data of cross section open-strange processes $e^+e^- \to K^+K^-$, K\bar{K}^{*}+c.c.$, K^{*+}K^{*-}$, K_1(1270)^+K^-$, K_1(1400)^+K^-$, K_2^{*}(1430)\bar{K}+c.c.$ and K(1460)^+K^-$ with support study hadron spectroscopy. We reveal contribution possible light vector mesons around 2 GeV reproduce reported from $e^+e^-$ annihilation which...
