The spin-1/2 model system with antiferromagnetic(AF) couplings on a J1-J2checkerboard lattice, known as the planar pyrochlore model, is strongly frustrated and associated with a two-to-one dimensional crossover. Using the Projected Entangled Simplex States tensor network ansatz, we identify a large number of nearly degenerate states in the frustrated region(J_(1)

Surging demand and reduced capacity in the ride-hailing industry have prompted numerous ride-hailing platforms to build their own car-rental services catering to drivers who do not possess private vehicles. However, the trade-off between the ride-hailing service and the car-rental service is an important issue that is still unclear in theory. Moreover, ride-hailing platforms are transitioning towards all-electric fleets in the context of Carbon Neutrality goals and government regulations. This paper considers a ride-hailing system comprising a monopolist ride-hailing platform, an electric vehicle (EV) rental firm, and a gasoline vehicle (GV) rental firm. Furthermore, we build a stylized model to study the sequential pricing of the system. The equilibrium outcomes show the significant impact of the ride-hailing platform’s decision to continue or withdraw offering EV rental services on EV and GV drivers’ net earnings, rental prices, and wages. The ride-hailing platform providing EV rental services increases EV drivers’ net earnings but decreases the GV driver wages and rental prices. However, the EV rental service offered by the ride-hailing platform does not necessarily lead to an increased total profit for the system. The improved profitability of the system by the ride-hailing platform providing EV rental services is contingent upon lower rider prices and higher fuel costs. The ride-hailing platform’s EV rental services provision also effectively fosters the ride-hailing fleet’s electrification. Furthermore, as the number of riders increases, the ride-hailing platform should reduce the commission rate for EV drivers to maintain competitiveness and profitability.

This paper reports the synthesis, properties and structure of (NH_4)_(12)[Cu_3(H_2O)_3(SbW_9O_33)_2]· 11H_2O. The compound was prepared by the depolymerization reaction of (NH4_)_(18)[(NH_4)Sb_9W21O_(86)]. nH_2O,which was proposed firstly as a method of preparing new heteropoly tungstoantimonate(Ⅲ). Its properties were characterized by IR, Raman, UV-VS spectra, TG-DTA thermal analysis, and X-ray single ctystal analysis. The crystal is orthorhombic, with space group D_(2h)^(16)-Pnma. The crystal data are: a=15.423(4), b=19.307(6), c=30.275(6), V=9015.0~3, Z=4, Dc=3.881 g/cm_3. The structure has been refined by full-matrix least squares method to a final R factor of 0.064 for 2652 reflections collected at room temperature. The heteropoly anion contains two a-B-SbW_9O_(33) subunits joined by three square-pyramidal CuO_4(OH_2).
