The core business of Mobile Network Operators (MNO) has moved from network management and phone services to service providing. In contrast to Information Communication Technology (ICT) service providers, MNOs handle large amounts of their customers’ context data and generated content, which can be used to bring value-added services to customers and therefore, generate solid revenues. Given this...

Ab initio theoretical results for the 2p- and 3p-hole states of an Mn(2+) ion are reported in order to determine the importance of atomic contributions to the photoelectron spectra of bulk MnO. A combined treatment of relativity and electron correlation reveals important physical effects that have been neglected in virtually all previous work. The many-body and relativistic effects included in ...

X-ray-absorption fine-structure measurements at the Mn K-edge as a function of temperature were performed on samples of La 1−x Ca x MnO 3 and La 0.67 Pb 0.33 MnO 3. All samples have a metal-insulator (MI) transition near the ferromagnetic transition, except the Ca 0.5 sample, which does not have a MI transition. Near T c for the MI samples, the Debye-Waller σ 2 for the Mn-O atom-pair increases ...

We report a novel design, based on a combination of lanthanide-doped upconversion nanoparticles and manganese dioxide nanosheets, for rapid, selective detection of glutathione in aqueous solutions and living cells. In this approach, manganese dioxide (MnO(2)) nanosheets formed on the surface of nanoparticles serve as an efficient quencher for upconverted luminescence. The luminescence can be tu...

We present evidence for an isostructural, first-order Mott transition in MnO at 105+/-5 GPa, based on high-resolution x-ray emission spectroscopy and angle-resolved x-ray diffraction data. The pressure-induced structural and spectral changes provide a coherent picture of MnO phase transitions from paramagnetic B1 to antiferromagnetic distorted B1 at 30 GPa, to paramagnetic B8 at 90 GPa, and to ...

Introduction: Nanostructured inorganic nanoparticles and core-shell structures can be used as MRI contrast agents with the advantages of flexible surface modification characteristics [1]. Manganese based nanoparticles have potential as agents that can be "activated" when taken into cells. For example, Mn oxides or Mn carbonates are insoluble at pH 7 but dissolve to release Mn at the lower pH fo...

This paper presents the results of a study investigating the influences of cultures on communication media choice within a multinational organization (MNO). A questionnaire was used to collect data from 121 respondents of a multinational organization across four countries; Australia, Korea, Thailand, and Malaysia. Cultural level difference was found to influence perception of media richness, ta...

In this Letter, we experimentally show that the room temperature ferromagnetism in the Mn-Zn-O system recently observed is associated with the coexistence of Mn(3+) and Mn(4+) via a double-exchange mechanism. The presence of the ZnO around MnO(2) modifies the kinetics of MnO(2)-->Mn(2)O(3) reduction and favors the coexistence of both Mn oxidation states. The ferromagnetic phase is associated wi...
