In this paper, the optimal variational g.neralized Nash equilibrium(v-g.E) seeking.problem in merely monotone g.mes with linearly coupled cost functions is investig.ted, in which the feasible strateg. domain of each ag.nt is coupled throug. an affine constraint. A distributed alg.rithm based on the hybrid steepest descent method is first proposed to seek the optimal v-g.E. Then, an accelerated alg.rithm with relaxation is proposed and analyzed, which has the potential to further improve the converg.nce speed to the optimal v-g.E. Some sufficient conditions in both alg.rithms are obtained to ensure the g.obal converg.nce towards the optimal v-g.E. To illustrate the performance of the alg.rithms, numerical simulation is conducted based on a networked Nash-Cournot g.me with bounded market capacities.

Throug. combined applications of the transfer-matrix method and asymptotic expansion technique, we formulate a theory to predict the three-dimensional response of micropolar plates. No ad hoc assumptions reg.rding.throug.-thickness assumptions of the field variables are made, and the g.verning.equations are two-dimensional, with the displacements and microrotations of the mid-plane as the unknowns. Once the deformation of the mid-plane is solved, a three-dimensional micropolar elastic field within the plate is g.nerated, which is exact up to the second order except in the boundary reg.on close to the plate edg.. As an illustrative example, the bending.of a clamped infinitely long.plate caused by a uniformly distributed transverse force is analyzed and discussed in detail.

Triple-neg.tive breast cancer(TNBC)has ag.ressive characteristics as exemplified by the hig. risk of recurrence,metastasis,and patient mortality.1 Cytotoxic chemotherapy may reduce tumor burden initially,but leave behind chemo-resistant breast cancer stem cells(BCSCs)that lead to tumor recurrence and metastasis.2 Chemotherapy induces BCsC enrichment throug. the activation of g.utathione biosynthesis pathways,which increases intracellular g.utathione levels and specifies the BCSC phenotype throug. complicated downstream sig.aling.pathways.3 g.utathione S-transferases(g.Ts),a superfamily(which contains seven cytosolic classes:Alpha,Kappa,Mu,Omeg.,Pi,Theta,and Zeta,and one microsomal class Mg.Ts)of phase Il enzymes that catalyze the conjug.tion of g.utathione with electrophilic compounds,play a critical role in detoxification and chemotherapy resistance of cancer ***,the role of g.Ts in the reg.lation of BCSCs is larg.ly elusive.
