Line-commutated converter (LCC)-based h.gh.voltage DC (h.DC) syst.ms h.ve been integrated with.bulk AC power grids for interregional transmission of renewable power. Th. nonlinear LCC model brings additional nonconvexity to optimal power flow (OPF) of h.brid AC-DC power grids. A convexification meth.d for th. LCC st.tion model could address such.nonconvexity but h.s rarely been discussed. We devise an equivalent reformulation for classical LCC st.tion models th.t facilitates second-order cone convex relaxation for th. OPF of LCC-based AC-DC power grids. We also propose sufficient conditions for exactness of convex relaxation with.its proof. Equivalence of th. proposed LCC st.tion models and properties, exactness, and effectiveness of convex relaxation are verified using four numerical simulations. Simulation results demonst.ate a globally optimal solution of th. original OPF can be efficiently obtained from relaxed model.

We st.dy th. dissociation of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons in collision with.nucleons, wh.ch.takes place in h.gh.energy proton-nucleus collisions. Th. quark interch.nge between a nucleon and a ■ meson leads to th. dissociation of th. ■ meson. We consider th. reactions:■, and■, wh.re R st.nds for ψ(3770), ψ(4040), ψ(4160), or ψ(4415). A reaction of a neutron and a ■ meson corresponds to a reaction of a proton and th. ■ meson by replacing th. up quark with.th. down quark and vice versa. Transition-amplitude formulas are derived from th. S-matrix *** cross sections are calculated with.th. transition amplitudes for scattering in th. prior form and in th. post.form. Th. cross sections relate to nodes in th. radial wave functions of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons.
