| 3 | Observation of ocean current response to 1998 Hurricane Georges in the Gulf of Mexico显示文摘The ocean current response to a hurricane on the shelf-break is examined. The study area is the DeSoto Canyon in the northeast Gulf of Mexico, and the event is the passage of 1998 Hurricane Georges with a maximum wind speed of 49 m/s. The data sets used for analy- sis consist of the mooring data taken by the Field Program of the DeSoto Canyon Eddy Intrusion Study, and simultaneous winds ob- served by NOAA (National Oceanic and Atmospheric Administration) Moored Buoy 42040. Time-depth ocean current energy density images derived from the observed data show that the ocean currents respond almost immediately to the hurricane with important differ- ences on and off the shelf. On the shelf, in the shallow water of 100 m, the disturbance penetrates rapidly downward to the bottom and forms two energy peaks, the major peak is located in the mixed layer and the secondary one in the lower layer. The response dissipates quickly after external forcing disappears. Off the shelf, in the deep water, the major disturbance energy seems to be trapped in the mixed layer with a trailing oscillation; although the disturbance signals may still be observed at the depths of 500 and 1 290 m. Verti- cal dispersion analysis reveals that the near-initial wave packet generated off the shelf consists of two modes. One is a barotropic wave mode characterized by a fast decay rate of velocity amplitude of 0.020 s-1, and the other is baroclinic wave mode characterized by a slow decay rate of 0.006 9 s-1. The band-pass-filtering and empirical function techniques are employed to the frequency analysis. The results indicate that all frequencies shift above the local inertial frequency. On the shelf, the average frequency is 1.04f in the mixed layer, close to the diagnosed frequency of the first baroclinic mode, and the average frequency increases to 1.07f in the thermocline. Off the shelf, all frequencies are a little smaller than the diagnosed frequency of the first mode. The average frequency decreases from 1.035f in the mixed layer to 1.02f in the thermocline, implying a trend for the shift in frequency of the oscillations towards f with the depth. | ZHENG Quanan LAI Ronald J HUANG Nortlen E PAN Jiayi LIU W Timothy | 2006 | Acta Oceanologica Sinica2006,25,1: | 20 |
| 4 | Adaptive Walking of a Quadrupedal Robot Based on Layered Biological Reflexes显示文摘A multiple-legged robot is traditionally controlled by using its dynamic model.But the dynamic-model-based approach fails to acquire satisfactory performances when the robot faces rough terrains and unknown environments.Referring animals' neural control mechanisms,a control model is built for a quadruped robot walking adaptively.The basic rhythmic motion of the robot is controlled by a well-designed rhythmic motion controller(RMC) comprising a central pattern generator(CPG) for hip joints and a rhythmic coupler(RC) for knee joints.CPG and RC have relationships of motion-mapping and rhythmic couple.Multiple sensory-motor models,abstracted from the neural reflexes of a cat,are employed.These reflex models are organized and thus interact with the CPG in three layers,to meet different requirements of complexity and response time to the tasks.On the basis of the RMC and layered biological reflexes,a quadruped robot is constructed,which can clear obstacles and walk uphill and downhill autonomously,and make a turn voluntarily in uncertain environments,interacting with the environment in a way similar to that of an animal.The paper provides a biologically inspired architecture,with which a robot can walk adaptively in uncertain environments in a simple and effective way,and achieve better performances. | ZHANG Xiuli E Mingcheng ZENG Xiangyu ZHENG Haojun | 2012 | Chinese Journal of Mechanical Engineering2012,25,4: | 10 |
| 5 | Applicability of five models to simulate water infiltration into soil with added biochar显示文摘As a soil amendment, biochar can reduce soil bulk density, increase soil porosity, and alter soil aggregates and thus affect the infiltration. Researchers have proposed and revised several theoretical models to describe the process of soil infiltration. Although these models have been successfully used to evaluate the soil infiltration in different scenarios in agricultural fields, little effort has been devoted to assess their performances in arid and semi-arid soils after the addition of biochar. A laboratory experiment was performed to study the infiltration characteristics of two typical Loess Plateau soils at three particle sizes(2–1, 1–0.25, and <0.25 mm) and five biochar application amounts(0, 10, 50, 100, and 150 g/kg). The performance of five models(i.e., the Philip model, Kostiakov model, Mezencev model, USDA-NRCS model, and Horton model) in simulating the infiltration process was then evaluated based on the adjusted coefficient of determination and a reduced Chi-Square test. Results indicated that the Horton model best simulated the water-infiltration process in an aeolian sandy soil with added biochar. However, the Mezencev model best simulated the infiltration process in a loamy clay soil(Eum-Orthic Anthrosol). The three-parameter model, i.e., Mezencev and Horton models can better describe the relationship between cumulative infiltration and infiltration time. In conclusion, biochar reduced the soil infiltration capacity of the aeolian sandy soil and increased that of the Eum-Orthic Anthrosol. | WANG Tongtong Catherine E STEWART MA Jiangbo ZHENG Jiyong ZHANG Xingchang | 2017 | Journal of Arid Land2017,9,5: | 9 |

| 9 | Frequency-multiplexing photon-counting multi-beam LiDAR显示文摘We report a frequency-multiplexing method for multi-beam photon-counting light detection and ranging(Li DAR),where only one single-pixel single-photon detector is employed to simultaneously detect the multibeam echoes.In this frequency-multiplexing multi-beam Li DAR,each beam is from an independent laser source with different repetition rates and independent phases.As a result,the photon counts from different beams could be discriminated from each other due to the strong correlation between the laser pulses and their respective echo photons.A 16-beam Li DAR system was demonstrated in three-dimensional laser imaging with 16 pulsed laser diodes at 850 nm and one single-photon detector based on a Si-avalanche photodiode.This frequencymultiplexing method can greatly reduce the number of single-photon detectors in multi-beam Li DAR systems,which may be useful for low-cost and eye-safe Li DAR applications. | TIANXIANG ZHENG GUANGYUE SHEN ZHAOHUI LI LEI YANG HAIYAN ZHANG E WU GUANG WU | 2019 | Photonics Research2019,7,12: | 4 |

| 11 | Discrete Particle Simulation of Gas-Solid Flow in Air-Blowing Seed Metering Device显示文摘In this paper,the gas and seed flow characters in the air-blowing seed metering device are investigated by using the coupled computational fluid dynamics and discrete element method(CFD-DEM)in three dimensions(3D).The method of establishing boundary model based on the computer-aided design(CAD)drawing,has been used to build the boundary model of seed metering device.The 3D laser scanning technique and multi-element method are adopted to establish the particle model.Through a combined numerical and experimental effort,using 3D CFD-DEM software,which is based on the in-house codes,the mechanisms governing the gas and solid dynamic behaviors in the seed metering device have been studied.The gas velocity field and the effect of different rotational speeds and air pressures on the seeding performance and particle velocity have been studied,similar agreements between numerical and experimental results are gained.This reveals that the 3D CFD-DEM model established is able to predict the performance of the air-blowing seed metering device.It can be used to design and optimize the air-blowing seed metering device and other similar agriculture devices. | Zhengquan Li Pei Zhang Yongchang Sun Chenglin Zheng Liang Xu Dianyu E | 2021 | Computer Modeling in Engineering & Sciences2021,,6: | 2 |

| 14 | An integrated microfluidic device for long-term culture of isolated single mammalian cells显示文摘We developed an integrated microfluidic chip for long-term culture of isolated single cells. This polydimethylsiloxane (PDMS) based device could accurately seed each single cell into different culture chambers, and isolate one chamber from each other with monolithically integrated pneumatic valves. We optimized the culture conditions, including the frequency of medium replacement and the introduction of conditioned medium, to keep the single cells alive for 4 days. We cultured a few hundred cells in a separated chamber on the same chip to continuously supply the conditioned medium into the culture chambers for single cells. This approach greatly facilitated the growth of single cells, and created a suitable microenvironment for observing cells' autonomous process in situ without the interference of other adjacent cells. This single cell colony assay is expandable to higher throughput, fitting the needs in the studies of drug screening and stem cell differentiation. | ZHENG ChunHong CHEN Gui’E PANG YuHong HUANG YanYi | 2012 | Science China Chemistry2012,55,4: | 2 |
