The superexchange mechanism in cobalt phthalocyanine (CoPc) thin films was studied by a low temperature scanning tunneling microscope. CoPc molecules were found to form one-dimensional antiferromagnetic chains the film. Collective spin excitations individual molecular measured with spin-flip associated inelastic electron spectroscopy. By spatially mapping spin-flipping channels submolecular precision, we are able explicitly identify specific orbitals that mediate interaction between molecules.
We propose a general theory on the standing waves (quasiparticle interference pattern) caused by scattering of surface states off step edges in topological insulators, which extremal points constant energy contour band play dominant role. Experimentally we image patterns both Bi$_2$Te$_3$ and Bi$_2$Se$_3$ films measuring local density using scanning tunneling microscope. The observed decay indices agree excellently with theoretical prediction: In Bi$_2$Se$_3$, only single index -3/2 exists;...
In this paper, a long-term workload management problem for multi-server edge computing with server collaboration is studied. the considered model, mobile users' computation-intensive tasks are generated dynamically over time and offloaded to associated servers according pre-determined subscription agreements. Upon receiving subscribed workload, each can then decide whether participate in enabling re-allocation (i.e., exchange) other heterogeneously configured servers. Unlike most of existing...
The network architecture is crucial to shaping a new generation of cellular network. As the foundation system, implies what and how services are provided, as well overall system efficiency, scalability, etc. This article proposes high-level designs 6G architecture. Three key innovation motivations analyzed gaps 5G identified according operator's experience in real large-scale deployment. Those observations help generate "Design Principles" about A novel termed "3 bodies, 4 layers, 5 planes...
Liquid air energy storage (LAES) is a promising technology in consuming renewable and electricity grid management. In the baseline LAES (B-LAES), compression heat only utilized heating inlet of turbines, large amount surplus, leading to low round-trip efficiency (RTE). this paper, an integrated system based on Kalina cycle (KC), called KC-LAES, proposed analyzed. system, surplus drive KC generate additional discharging process. An energetic model developed evaluate performance KC-LAES....
Many applications in distributed systems rely on underlying lossless networks to achieve required performance. Existing network solutions propose different hop-by-hop flow controls guarantee zero packet loss. However, another crucial problem called deadlock occurs concomitantly. Once the system traps a deadlock, large part of would be disabled. avoidance focus all their attentions breaking cyclic buffer dependency eliminate circular wait (one necessary condition deadlock). These solutions,...
The charge states of single molecular magnetic chains were manipulated with a scanning tunneling microscope and identified by spin-flip inelastic spectroscopy. We show that the charged neutral have different spin structures therefore exhibit features associated processes in spectra. experiment demonstrates general approach for detecting at nanometer scale more straightforward manner than using indirect information.
Editor's note:From a system architecture perspective, 3D technology can satisfy the high memory bandwidth demands that future multicore/manycore architectures require. This article presents DRAM design and potential for using stacking both L2 cache main in multicore architecture.—Yuan Xie, Pennsylvania State University
Time-Sensitive Networking (TSN), as an enhancement based on Ethernet, can ensure deterministic traffic transmission with low delays and minimal jitters. However, TSN switches have only eight priority queues inherited from Ethernet at each egress port, which limits the flexibility efficiency of scheduling, well support for developing management mechanisms. Although per-flow boost scheduling Quality Service (QoS), static hardware in are considered unpratical due to resource limits. In this...
Recently, HTTP-based adaptive video streaming has been widely adopted in the Internet. Up to now, is standardized as Dynamic Adaptive Streaming over HTTP (DASH), where a client-side player can dynamically pick bitrate level according perceived network conditions. Actually, not only available bandwidth varying, but also chunk sizes same significantly fluctuate, which influences adaptation. However, existing adaptation algorithms do accurately involve size variation, leading performance...
