| 1 | The design and fabrication on gate type resonant tunneling transistor显示文摘In light of fabricating resonant tunneling diode(RTD),in this paper a GaAs-based resonant tunneling transistor with gate structure(GRTT)has been designed and fabricated successfully.A systematic depiction centers on the designs of material structure,device structure,photo-lithography mask,fabrication of device and the measurement and analysis of parameters.The fabricated GRTT has a maximum PVCR of 46 and a maximum transconductance of 8 mS.The work lays the foundation for further improve-ment on the performance and parameters of RTT. | Weilian GUO Huilai LIANG Ruiliang SONG Shilin ZHANG Luhong MAO Liuchang HU Jianheng LI Haitao QI Zhen FENG Guoping TIAN Yuehui SHANG Yongqiang LIU Yali LI Mingwen YUAN Xiaobai LI | 2008 | Frontiers of Electrical and Electronic Engineering in China2008，3，2： | 0 |
| 2 | A dynamic holographic modelling method of digital twin scenes for bridge construction显示文摘Holographic projection technology can provide a more intuitive and efficient visualization effect for a digital twin bridge construction scene.However,pre-rendering methods in the existing research work are usually used to implement holographic visualization,which is static display.The above-mentioned methods for static display have many shortcomings,such as poor adaptability,low rendering efficiency and lack of real-time.A dynamic holographic modelling approach is proposed for the augmented visualization of digital twin scenes for bridge construction.Firstly,a dynamic segmentation algorithm with adaptive screen size was designed to high-efficiently generate holographic scenes.Secondly,a motion blur control method was designed to improve the rendering efficiency of holographic scenes according to human visual characteristics.Finally,a prototype system was developed,and the corresponding experimental analysis was completed.The experimental results show that the method proposed in this article can support adaptive screen size image segmentation and real-time generation of holographic scenes for bridge construction.The amount of scene data can be reduced to more than 30%,which significantly improves rendering efficiency and reduces glare. | Jianlin Wu Jun Zhu Jinbin Zhang Pei Dang Weilian Li Yukun Guo Lin Fu Jianbo Lai Jigang You YaKun Xie Ce Liang | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 3 | Cancer cells corrupt normal epithelial cells through miR-let-7c-rich small extracellular vesicle-mediated downregulation of p53/PTEN显示文摘Tumor volume increases continuously in the advanced stage, and aside from the self-renewal of tumor cells, whether the oncogenic transformation of surrounding normal cells is involved in this process is currently unclear. Here, we show that oral squamous cell carcinoma(OSCC)-derived small extracellular vesicles(s EVs) promote the proliferation, migration, invasion, and epithelial-mesenchymal transition(EMT) of normal epithelial cells but delay their apoptosis. In addition, nuclear-cytoplasmic invaginations and multiple nucleoli are observed in s EV-treated normal cells, both of which are typical characteristics of premalignant lesions of OSCC. Mechanistically, mi Rlet-7c in OSCC-derived s EVs is transferred to normal epithelial cells, leading to the transcriptional inhibition of p53 and inactivation of the p53/PTEN pathway. In summary, we demonstrate that OSCC-derived s EVs promote the precancerous transformation of normal epithelial cells, in which the mi R-let-7c/p53/PTEN pathway plays an important role. Our findings reveal that cancer cells can corrupt normal epithelial cells through s EVs, which provides new insight into the progression of OSCC. | Weilian Liang Yang Chen Hanzhe Liu Hui Zhao Tingting Luo Hokeung Tang Xiaocheng Zhou Erhui Jiang Zhe Shao Ke Liu Zhengjun Shang | 2022 | International Journal of Oral Science2022，14，4： | 0 |
