Service-dominant logic for exploring modular business service system

Investigating the management of the three dimensions of modular business service system from the perspective of the service-dominant (S-D) logic. An integrated approach with an abductive research process in theory building was conducted through case study. The results show that ten foundational premises of S-D logic, especially service -focused, customer-oriented, and rational views can be applied in defining and managing the modular business service system constructed by service modularization

The swap operation in the two-qubit Heisenberg XXZ model-effects of anisotropy and magnetic field

In this paper we study the swap operation in a two-qubit anisotropic XXZ model in the presence of an inhomogeneous magnetic field. We establish the range of anisotropic parameter within which the swap operation is feasible. The swap errors caused by the inhomogeneous field are evaluated

catena-Poly[[(1,10-phenanthroline-κ2 N,N′)zinc]-μ-furan-2,5-dicarboxyl­ato-κ4 O 2,O 2′:O 5,O 5′]

In the title coordination polymer, [Zn(C6H2O5)(C12H8N2)]n, an infinite chain is formed along [010] by linking the chelated {Zn(phen)} entities (phen is 1,10-phenanthroline) with two carboxyl­ate groups of the furan-2,5-dicarboxyl­ate ligand. The ZnII atom shows trigonal–prismatic coordination

catena-Poly[[[aqua­bis­(1H-imidazole-κN 3)copper(II)]-μ-furan-2,5-di­car­boxylato-κ2 O 2:O 5] trihydrate]

In the title cooridnation polymer, {[Cu(C6H2O5)(C3H4N2)2(H2O)]·3H2O}n, an infinite chain is formed along [001] by linking of the Cu(C3N2H4)2(H2O) entities with two bridging monodentate carboxyl­ate groups of two different furan-2,5-dicarboxyl­ate dianions. The geometry of the Cu2+ ion is a square-based pyramid with the water atom in the apical position and the ligand O and N atoms in a trans orientation. The dihedral angle between the imidazole planes is 83.96 (14)°. Ow–H⋯O and Ni–H⋯O (w = water and i = imidazole) hydrogen bonds help to establish the packing

Revising inelastic dark matter direct detection by including the cosmic ray acceleration

The null signal from collider and dark matter (DM) direct detector experiments makes the interaction between DM and visible matter too small to reproduce the correct relic density for many thermal DM models. The remaining parameter space indicates that two almost degenerated states in the dark sector, the inelastic DM scenario, can co-annihilate in the early universe to produce the correct relic density. Regarding the direct detection of the inelastic DM scenario, the virialized DM component from the nearby halo is nonrelativistic and not able to excite the DM ground state, even if the relevant couplings can be considerable. Thus, a DM with a large mass splitting can evade traditional virialized DM direct detection. In this study, we connect the concept of cosmic-ray accelerated DM in our Milky Way and the direct detection of inelastic scattering in underground detectors to explore spectra that result from several interaction types of the inelastic DM. We find that the mass splitting $\delta<\mathcal{O}(1~{\rm MeV})$ can still be reachable for cosmic ray accelerated DM with mass range $1~{\rm MeV}<m_{\chi_1}<100~{\rm GeV}$ and sub-GeV light mediator using the latest PandaX-4T data, even though we conservatively use the astrophysical parameter (effective length) $D_{\rm eff}=1$ kpc.Comment: 38 pages, 12 figures, JHEP accepted versio
