The resolution measurement of 3D reconstructed density map in single particle reconstruction is an important and still an open *** this paper,we propose a new protocol to measure the resolution just from the reconstructed density *** approach estimates spectral signal-to-noise ratio(SSNR) of 3D reconstructed map by computing the ratio of signal power to noise power in frequency *** power distributions of signal and noise are estimated from structure particle region and surrounding region segmented by applying a mask *** proposed protocol of calculating SSNR,which we term mask-SSNR(mSSNR),is independent of the reconstruction algorithms and can be used for density maps reconstructed with any reconstruction ***,the mSSNR neither needs to split the dataset into halves like the Fourier shell correlation(FSC) approach,nor any original images or intermediate data like other SSNR calculation methods in this *** mSSNR provides a direct calculation of SSNR based on its original definition,and is proven to be a better approach.

The ever increasing wireless data services, such asimaging, video, audio, multimedia, etc., have de-mands for the very high speed wireless communicationsand network, which are unfortunately a bottleneck whencombining with the wireline core network. Users' arenow expecting high quality of experience with low-costdevices, ubiquitous connectivity, energy efficiency, highreliability, or even ultra-low latency if a vehicle terminalis applied.

Suitable optimal scheduling model is essential to ensuring water-supply pump stations working in high efficiency area. Based on accurate poly-fitted water pump characteristic curves, an optimal scheduling models of water-supply pump stations based on its least shaft power is proposed here. Since the constraints here are mixed with inequality, nonlinear conditions, continuous variables and discrete variables, an improved adaptive genetic algorithm(IAGA) is developed and used here, which is equipped with adaptive crossover and mutation operators based on sigmoid function, as well as adaptive penalty function factor using simulated annealing. The experimental results, comparing with the results based on simple genetic algorithm, show that pump optimal operation can ensure that all the pumps would operate in high efficiency area and meanwhile, reduce electricity energy effectively, which, as a result, implies that IAGA is more suitable for optimal scheduling of water-supply pump station.
