The objective of this study was to retrieve daily composite soil moisture by jointly using brightness temperature observations from multiple operating satellites for near real-time application with better coverage and higher *** approach was to first apply the single-channel brightness radiometric algorithm to estimate soil moisture from the respective brightness temperature observations of the SMAP,SMOS,AMSR2,FY3B,and FY3C satellites on the same day and then produce a daily composite dataset by averaging the individual satellite-retrieved soil *** further evaluated our product,the official soil moisture products of the five satellites,and the ensemble mean (i.e.,arithmetic mean) of the five official satellite soil moisture products against ground observations from two networks in Central Tibet and Anhui Province,*** results show that our product outperforms the individual released products of the five satellites and their ensemble means in the two validation *** root mean square error (RMSE ) values of our product were 0.06 and 0.09 m3/m3 in Central Tibet and Anhui Province,*** to the ensemble mean of the five satellite products,our product improves the accuracy by 9.1% and 57.7% in Central Tibet and Anhui Province,*** demonstrates that jointly using brightness temperature observations from multiple satellites to retrieve soil moisture not only improves the spatial coverage of daily observations but also produces better daily composite products.

Experimental evidence has demonstrated that environmental hazards can induce neurodegeneration such as Alzheimer's disease(AD)^([1]).The pathogenesis of AD,characterized by a gradual cognitive decline,overproduction ofβ-amyloid(Aβ),and hyperphosphorylated tau in specific brain areas,is considered to involve the interaction of several internal(individual)and external environmental factors.

Model of Production Planning and Scheduling in Shop Floor Based on Collaboration and Competition

引用

Wuhan University Journal of Natural Sciences 2002年第1期7卷 77-81页

作者： liu Shi-ping Rao Yun-qing Zhang Jie li Pei-gen Intelligent Manufacturing Laboratory School of Mechanical Sci. and Eng. Huazhong Univ. of Sci. and Technol. Wuhan 430074 Hubei China

The planning and scheduling in real shop floor is actually achieved by coordination between different persons. In this process, cooperation is mainstream, but competition also exists, for example, the competition between different groups, operators with the same skill, etc. In multi-agent based shop floor management and control system, this competition and cooperation relation must be embodied. The general process of shop floor production planning and scheduling is studied, and a colored Petri-net model for the competition and cooperation process of three main agents in such system to achieve shop floor production planning and scheduling is presented. The evaluating method of bids in bidding process that especially embodies the competition relationship is also presented. This colored Petri-net model gives a clear illustration of this complex coordination process to system designers, effectively promotes the cooperative development.

lithography simulation is key to the preparation of mask data and verification of mask patterns [1], which enhances design-to-wafer fidelity and minimizes distortions. However,the complexity of lithography simulation has tremendously increased with the decrease in feature size, prolonging the simulation cycle. Hence, an accurate and fast lithography simulation is in great demand.

Chemical Vapor Deposition Growth of Large-Area Monolayer MoS_2 and Fabrication of Relevant Back-Gated Transistor

引用

Chinese Physics Letters 2019年第3期36卷 70-73页

作者： Jian-Ying Chen Lu liu Chun-xia li Jing-Ping Xu School of Optical and Electronic Information Huazhong University of Science and Technology Shenzhen Institution of Information Technology

A closed two-temperature-zone chemical vapor deposition(CVD) furnace was used to grow monolayer molybdenum disulfide(MoS_2) by optimizing the temperature and thus the evaporation volume of the Mo precursor. The experimental results show that the Mo precursor temperature has a large effect on the size and shape transformation of the monolayer MoS_2, and at a lower temperature of 760°C, the shape starts to change from a triangle to a truncated triangle. A large-area triangular monolayer MoS_2 with a side length of 145 °m is achieved at 760°***, the as-grown monolayer MoS_2 is used to fabricate back-gated transistors by means of electron beam lithography to evaluate the electrical properties of MoS_2 thin films. The MoS_2 transistors with monolayer MoS_2 grown at 760°C exhibit a high on/off current ratio of 10~6, a mobility of 1.92 cm^2/Vs and a subthreshold swing of 194.6 mV/dec, demonstrating the feasible approach of CVD deposition of monolayer MoS_2 and the fabrication of transistors on it.
