Software-defined networking (SDN) is a revolutionary network architecture that separates out network control functions from the underlying equipment and is an increasing trend to help enterprises build more manageable data centers where big data processing emerges as an important part of applications. To concurrently process large-scale data, MapReduce with an open-source implementation named Hadoop...
Construction of smart city has become a historical trend in the world. The management of underground pipes and the intelligent concrete are the main part of building smart city in China. Compared with the available electronic marker system, SAW-RFID system has shown excellent properties: truly passive, strong penetrating capability, long service-life, sensing and ID integration, and etc. Thus, SAW-RFID...
The aim of this study is to investigate how the intracellular ROS responds to different degrees of sonoporation. Using a customized platform for 1.5-MHz ultrasound exposure (13.33-μs duration and 0.70-MPa peak negative pressure) and observing the dynamics of sonoporation and intracellular ROS at the single-cell level, we quantified the exogenous molecular uptake and intracellular ROS indicator to...
Some methods to enhance penetration depth further are proposed and demonstrated. A second harmonics SPUDT, new criterion of matching and high reflectivity reflector are utilized to reduce the losses of SAW tag. The enhancement of reading system including high signal processing gain and compensate the center frequency mismatch between reader and SAW tag are achieved. Furthermore, the effect of decreasing...
To develop and realize the sonoporation-based therapeutic applications, it is important to understand underlying cellular bioeffects involved in the sonoporation. It is known that appropriate reactive oxygen species (ROS) is necessary to maintain normal physiological functionality, but excessive ROS would trigger downstream adverse bioeffects. However, it is still unclear about ROS response in the...
Timing jitter optimization of mode-locked lasers is essential for applications that require high temporal resolution. In this work, both numerical simulation and experiments show that the Gordon-Haus timing jitter of large-net-dispersion mode-locked fiber lasers can be removed with an intra-cavity narrow band-pass filter. As a result, the filtered lasers exhibit rather low timing jitter that is immune...
We demonstrate efficient self-similar pulse evolution and noise suppression in a free-running nonlinear femtosecond fiber amplifier based on the pump-wavelength optimization. Experiments and simulations show the broader and flatter absorption cross-sections around 915 nm can reduce the influences of the gain shaping and fluctuations of pump laser diodes (LDs). 50-fs transform-limited pulses are generated...
We report on a hybrid phototransistor that consists of In2O3 nanowire covered with multilayer WSe2. The absorption of infrared light in multilayer WSe2 forms the accumulation of photogenerated carriers at the interface between WSe2 and In2O3 to enhance the conductance of nanowire. A responsivity of ∼104 A W−1 and an on/off ratio of ∼106 are obtained with 940 nm light irradiation at room temperature...
Network planning is a complicated and arduous project, with a large scale of uncertain factors and a wide range of characteristics. Based on the technical characteristics of the power grid, a scientific and comprehensive index system is established in this paper. Using the judgment matrix and intrinsic entropy value to determine the index weight of each level, the fuzzy analytic hierarchy process...
Load serving entities (LSEs) purchase energy from markets and sell it to their customers. As a profit-seeking organization, the aim of the LSE is mainly to make the profit maximal. As the electricity market is liberated, consumers become active to participate in it and may decide to modify the profile of their demand to reduce their electricity costs, which affects strategies of LSEs. Hence, demand...
Spinning reserve (SR) is an important resource, which is used by system operators to maintain system security and improve operational reliability. A certain capacity of spinning reserve must be configured in every power system. In order to make the optimization of SR more practical, a new model to optimize spinning reserve of power system with transmission line fault is proposed, which is based on...

The aim of this investigation is to determine if the heterogeneous sonoporation depends on the microbubble size. Using a customized ultrasound exposure and observation setup, we observed sonoporation dynamics at the single-cell level and quantified exogenous molecular uptake levels to evaluate the degree of sonoporation. The non-uniform size distribution of SonoVue microbubbles themselves allowed...
