Capacity and Delay Tradeoff of Secondary Cellular Networks with Spectrum Aggregation
Lingyu Chen, Chen Liu, Xuemin Hong +3
Cellular communication networks are plagued with redundant capacity, which results in low utilization and cost-effectiveness of network capital investments. The redundant capacity…
On derived Hall numbers for tame quivers
Shiquan Ruan, Haicheng Zhang
In the present paper we study the derived Hall algebra for the bounded derived category of the nilpotent representations of a tame quiver over a finite field. We show that for any…
Physical quantities and spatial parameters in the complex octonion curved space
Zi-Hua Weng
The paper focuses on finding out several physical quantities to exert an influence on the spatial parameters of complex-octonion curved space, including the metric coefficient, con…
The universal "heartbeat" oscillations in black hole systems accross the mass-scale
Qingwen Wu, Bozena Czerny, Mikolaj Grzedzielski +7
The hyperluminous X-ray source (HLX-1, the peak X-ray luminosity ) near the spiral galaxy ESO 243-49 is possibly the best candidate for intermediate ma…
One-Dimensional Self-Organization and Nonequilibrium Phase Transition in a Hamiltonian System
Jiao Wang, Giulio Casati
Self-organization and nonequilibrium phase transitions are well known to occur in two- and three- dimensional dissipative systems. Here, instead, we provide numerical evidence that…
Central Engine of Late-Time X-ray Flares with Internal Origin
Hui-Jun Mu, Wei-Min Gu, Shu-Jin Hou +5
This work focuses on a sample of seven extremely late-time X-ray flares with peak time , among which two flares can be confirmed as the late-time activity…
