There is a strong evidence supporting the hypothesis of synaptic dysfunction as a m.jor contributor to neural circuit and network disruption underlying em.tional and m.od dysregulation in psychiatric disorders(Sim.ons et al.,2024).Diverse sets of distinct m.lecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through com.lex interactions organized by num.rous m.ltivalent protein scaffolds,including the fam.ly of proteins known as A-kinase anchoring proteins(AKAPs).

We show that a Vm. based theoretical input a.lows for a significantly im.roved accuracy for the hadronic vacuum.polarization of the photon which contributes to the theoretical estim.te of the m.on g-2. We also show that the only experim.ntal piece of inform.tion in the τ decay which cannot be accounted for within this Vm. fram.work is the accepted value for Br（τ→ππvτ）, while the T spectum.lineshape is in agreem.nt with expectations from.e^＋e^- annihilations.

This study exam.nes the perform.nce of integration m.thods for hybrid sim.lation of large and com.lex structural system. in the context of structural collapse due to seism.c excitations. The target application is not necessarily for real-tim. testing, but rather for m.dels that involve large-scale physical sub-structures and highly nonlinear num.rical m.dels. Four case studies are presented and discussed. In the first case study, the accuracy of integration schem.s including two widely used m.thods, nam.ly, m.dified version of the im.licit Newm.rk with fixed-num.er of iteration （iterative） and the operator-splitting （non-iterative） is exam.ned through pure num.rical sim.lations. The second case study presents the results of 10 hybrid sim.lations repeated with the two aforem.ntioned integration m.thods considering various tim. steps and fixed-num.er of iterations for the iterative integration m.thod. The physical sub-structure in these tests consists of a single-degree-of-freedom.（SDOF） cantilever colum. with replacea.le steel coupons that provides repeata.le highly- nonlinear behavior including fracture-type strength and stiffness degradations. In case study three, the im.licit Newm.rk with fixed-num.er of iterations is applied for hybrid sim.lations of a 1：2 scale steel m.m.nt fram. that includes a relatively com.lex nonlinear num.rical substructure. lastly, a m.re com.lex num.rical substructure is considered by constructing a nonlinear com.utational m.del of a m.m.nt fram. coupled to a hybrid m.del ofa 1：2 scale steel gravity fram.. The last two case studies are conducted on the sam. porotype structure and the selection of tim. steps and fixed num.er of iterations are closely exam.ned in pre-test sim.lations. The generated unbalance forces is used as an index to track the equilibrium.error and predict the accuracy and stability of the sim.lations.
