Structural Transition in Random Mappings
In this paper we characterise the structural transition in random mappings with in-degree restrictions. Specifically, for integers 0 6 r 6 n, we consider a random mapping model T̂ r n from [n] = {1, 2, . . . , n} into [n] such that Ĝn, the directed graph on n labelled vertices which represents the mapping T̂ r n , has r vertices that are constrained to have in-degree at most 1 and the remaining v...
متن کاملBenchmarking Structural Change in Transition *
The transition to market-based economic systems in the countries of Central and Eastern Europe and the former Soviet Union involves fundamental shifts in the allocation of resources and deep changes in the structure of production and employment. This paper uses a simple model of economic development and structural change with technology spillovers to benchmark structural change in the transitio...
متن کاملStructural Phase Transition Accompanied by Metal - Insulator Transition in PrRu4P12
A structural phase transition has been found using electron diffraction technique in PrRu4P12 accompanied by a metal insulator (M I) transition (TMI = 60K). Weak superlattice spots appeared at (H, K, L) (H + K + L = 2n + 1; n is an integer) position at a temperature of T = 12 K and 40 K. Above T = 70 K, the spots completely vanished. The space group of the low temperature phase is probably Pm 3...
متن کاملThe Effect of Transition Metals Incorporation on the Structural and Magnetic Properties of Magnesium Oxide Nanoparticles
Pure and doped magnesium oxide nanoparticles were successfully synthesized employing a sol-gel process. The synthesized nanoparticles were characterized by thermal differential analysis, X-ray powder diffraction, transmission electron microscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometer. X-ray diffraction patterns confirmed the crysta...
متن کاملSkyrmion lattice structural transition in MnSi
Magnetic skyrmions exhibit particle-like properties owing to the topology of their swirling spin texture, providing opportunities to study crystallization of topological particles. However, they mostly end up with a triangular lattice, and thus, the packing degree of freedom in the skyrmion particles has been overlooked so far. We report a structural transition of the skyrmion lattice in MnSi. ...
