TL;DR: Numerical simulations and comparisons indicate the satisfactory performance of the proposed task offloading scheme for maintaining a relatively high fairness index for energy consumption and low task delay in the fog computing networks.
Abstract: Fog computing is expected to cope with the long latency and heavy link burden existing in cloud- based networks. Computing tasks of the terminal node can be offloaded to nearby fog nodes thus achieving much lower processing delay than that of cloud-based networks. Existing researches for energy consumption in fog computing networks mainly focus on the total energy consumed by processing a task. However, fair offloading among multiple fog nodes while maintaining a low task delay is of great significance especially for the battery-powered fog nodes. This paper proposes an analytical framework of the fair task offloading for fog computing networks. Task delay and the corresponding energy consumption are formulated. Then, a fairness scheduling metric is constructed for each fog node. A two-step Fair Task Offloading (FTO) scheme is proposed finally, which selects offloading fog nodes according to the fairness metric and then offloads tasks to the selected nodes based on a rule that minimizes the task delay. Numerical simulations and comparisons indicate the satisfactory performance of the proposed task offloading scheme for maintaining a relatively high fairness index for energy consumption and low task delay in the fog computing networks.

TL;DR: This work provides a new avenue for the rational design of an ESIPT molecule to achieve white-light generation under mild conditions.
Abstract: The synthesis and photophysics of two novel 2-(2'-hydroxyphenyl)-benzothiazole (hbt) derivatives are presented. the electron-withdrawing trifluoromethyl (cf3) group in compound 1 facilitates the deprotonation of the phenolic hydroxy group. well-resolved triple fluorescence from the enol, keto, and phenolic anion, which ranges from 350 to 600 nm, was detected for 1 in ethanol, which marks the first time triple fluorescence from an excited-state intramolecular proton transfer (esipt) molecule has been reported. both triphenylamine and cf3 were introduced into derivative 2. intramolecular charge transfer and the "red-edge effect" resulted in the bathochromic shift of dual fluorescence of 2. triple fluorescence was also observed for 2 in ethanol. in mixed acetonitrile and ethanol, pure white-light emission with cie coordinates of (0.33, 0.33) and a quantum yield of 0.25 was achieved for 2. this work provides a new avenue for the rational design of an esipt molecule to achieve white-light generation under mild conditions.

TL;DR: In this paper, a novel design of boresight and conical pattern reconfigurable antenna with the capability of 360° polarization scanning is presented, which provides adaptive-polarization reception between a transmitter and a receiver.
Abstract: A novel design of boresight and conical pattern reconfigurable antenna with the capability of 360° polarization scanning is presented in this paper. At boresight mode, the antenna produces a continuously reconfigurable polarization over 360° in the azimuth plane, which provides adaptive-polarization reception between a transmitter and a receiver. The antenna is analyzed in terms of the electric field with an explanation of the generation of TM11 and TM02 resonant modes, which provides an innovative method of designing pattern reconfigurable antennas for the WLAN applications. The proposed method is validated by a good agreement between simulation and experimental results for an antenna designed to provide boresight and conical pattern switching at 2.4 GHz. The gain of 6.05 dBi and efficiency of 86.7% are measured in the boresight mode, corresponding to 4.39 dBi and 82.4% at conical mode.

TL;DR: In this paper, the authors employed linear, branch and mixed linear-and-branch side-chain attached benzooxadiazole (BO) as the acceptor (A) units in poly[benzodithiophene-thiophenefluorothienothiamothiophene] (PBDTTBO) conjugated polymers and monitored their interactions with poly[bldt 7-TH] (PTB7-TH), both of which featured the same benzodithioxhene (BDTT) donor (D) units.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: Comparing the results to the fastest reported vectorized Cray Y-MP and C90 algorithm shows that the current generation of parallel machines is competitive with conventional vector supercomputers even for small problems.
Abstract: Three parallel algorithms for classical molecular dynamics are presented. The first assigns each processor a fixed subset of atoms; the second assigns each a fixed subset of inter-atomic forces to compute; the third assigns each a fixed spatial region. The algorithms are suitable for molecular dynamics models which can be difficult to parallelize efficiently—those with short-range forces where the neighbors of each atom change rapidly. They can be implemented on any distributed-memory parallel machine which allows for message-passing of data between independently executing processors. The algorithms are tested on a standard Lennard-Jones benchmark problem for system sizes ranging from 500 to 100,000,000 atoms on several parallel supercomputers--the nCUBE 2, Intel iPSC/860 and Paragon, and Cray T3D. Comparing the results to the fastest reported vectorized Cray Y-MP and C90 algorithm shows that the current generation of parallel machines is competitive with conventional vector supercomputers even for small problems. For large problems, the spatial algorithm achieves parallel efficiencies of 90% and a 1840-node Intel Paragon performs up to 165 faster than a single Cray C9O processor. Trade-offs between the three algorithms and guidelines for adapting them to more complex molecular dynamics simulations are also discussed.
