Network slicing (NS) has been well discussed in the transport network (TN) and core network (CN) domains. This paper extends it to the radio access network (RAN) domain, and the NS in RAN, TN and CN domains is defined as end-to-end (E2E) NS system. The advantages of using NS in the RAN domain with two-level resource allocation scheme are studied and shown by numerical simulations. Then the E2E NS system architecture and components are proposed and demonstrated with hardware and software. The demonstration shows the capability with very fine spectral granularity, and the slice creation, delete and adjustment schemes in sub-minute time, which could be used in the operator's network. INDEX TERMS End-to-end network slicing, radio access network, spectrum allocation, demonstration.

[ASN]2[MnBr4] is a novel multifunctional-material-integrated compound, which simultaneously exhibits prominent dielectric/NLO/fluorescent triple switching triggered by the thermal/electric/optical signal.

Single crystal growth of the pyrochlores R 2 Ti 2 O 7 (R = rare earth)by the optical floating-zone method AbstractWe report a systematic study on the crystal growth of the rare-earth titanates R 2 Ti 2 O 7(R = Gd, Tb, Dy, Ho, Y, Er, Yb and Lu) and Y-doped Tb 2−x Y x Ti 2 O 7 (x = 0.2 and 1) using an optical floating-zone method. High-quality single crystals were successfully obtained and the growth conditions were carefully optimized. The oxygen pressure was found to be the most important parameter and the appropriate ones are 0.1-0.4 MPa, depending on the radius of rare-earth ions. The growth rate is another parameter and was found to be 2.5-4 mm/h for different rare-earth ions. X-ray diffraction data demonstrated the good crystallinity of these crystals. The basic physical properties of these crystals were characterized by the magnetic susceptibility and specific heat measurements.
