| 3 | Networked TT&C for Mega Satellite Constellations:A Security Perspective显示文摘Satellite constellations are promising in enabling the global Internet.However,the increasing constellation size also complicates tracking,telemetry and command(TT&C)systems.Traditional groundbased and space-based approaches have encountered significant obstacles due to,e.g.,the limited satellite visible arc and long transmission delay.Considering the fast development of intersatellite communications,synergy among multiple connected satellites can be exploited to facilitate TT&C system designs.This leads to networked TT&C,which requires much less predeployed infrastructures and even performs better than traditional TT&C systems.In this paper,we elaborate system characteristics of networked TT&C compared with traditional ground-based and spacebased TT&C,and propose the unique security challenges and opportunities for networked TT&C,which includes secure routing and trust mechanisms.Furthermore,since networked TT&C is a novel scenario with few relevant researches,we first investigate the current researches on secure routing and trust mechanisms for traditional terrestrial and satellite networks,and then accordingly deliver our security perspectives considering the system characteristics and security requirements of networked TT&C. | Yafeng Zhan Guanming Zeng Xiaohan Pan | 2022 | China Communications2022,19,9: | 1 |
| 4 | Revisit of event-based rainfall characteristics at Shapotou area in northern China显示文摘Distribution of rainfall event sizes and interval lengths between events are important characteristics of arid and semi-arid climates. Understanding their importance will contribute to our ability to understand ecosystem dynamics in these regions. Rainfall event timing and magnitude are important drivers of ecosystem processes and are instrumental in creating landscape heterogeneity in arid and semi-arid regions. Rainfall event characteristics were analyzed using an automatic tipping-bucket rain-gauge record across the entire summer monsoon season from 2008 to 2015 at the arid desert area of Shapotou in the Tengger Desert, China. Changing the minimum inter-event time(MIT) from 30 min to 24 h alters the number of rainfall events from 64 to 25 for the event depth larger than 0.1 mm. The mean rainfall intensity declined from 0.95 mm/h to 0.53 mm/h, and the geometric mean event duration rose from 0.55 h to 4.4 h. The number of rainfall events, mean rainfall intensity, and geometric mean event duration differed under different criteria of individual rainfall depths, except that for an individual rainfall depth of 0.5, 1.0, and 5.0 mm. The aforementioned features differed only at the lowest range of the mean rainfall intensity and depth for MIT=3 and 6 h. These findings suggest that identification of event-based rainfall in this specific arid region can be better achieved by setting the MIT at six hours. The wide variation in rainfall event properties indicate the need for paying more attention to the proper selection and reporting of event criteria in studies that adopt event-based data analysis. This is especially true in quantifying effective rainfall for soil water replenishment in terms of rainfall depth and intensity with infrequent rainfall events. | XinPing Wang YaFeng Zhang RuiHu YanXia Pan HaoJie Xu Wei Shi YanXia Jin Hiroshi Yasuda | 2016 | Research in Cold and Arid Regions2016,8,6: | 1 |

| 6 | Spatiotemporal regulation of ubiquitin-mediated protein degradation via upconversion optogenetic nanosystem显示文摘Protein degradation technology,which is one of the most direct and effective ways to regulate the life activities of cells,is expected to be applied to the treatment of various diseases.However,current protein degradation technologies such as some small-molecule degraders which are unable to achieve spatiotemporal regulation,making them difficult to transform into clinical applications.In this article,an upconversion optogenetic nanosystem was designed to attain accurate regulation of protein degradation.This system worked via two interconnected parts:1)the host cell expressed light-sensitive protein that could trigger the ubiquitinproteasome pathway upon blue-light exposure;2)the light regulated light-sensitive protein by changing light conditions to achieve regulation of protein degradation.Experimental results based on model protein(Green Fluorescent Protein,GFP)validated that this system could fulfill protein degradation both in vitro(both Hela and 293T cells)and in vivo(by upconversion optogenetic nanosystem),and further demonstrated that we could reach spatiotemporal regulation by changing the illumination time(0–25 h)and the illumination frequency(the illuminating frequency of 0–30 s every 1 min).We further took another functional protein(The Nonstructural Protein 9,NSP9)into experiment.Results confirmed that the proliferation of porcine reproductive and respiratory syndrome virus(PRRSV)was inhibited by degrading the NSP9 in this light-induced system,and PRRSV proliferation was affected by different light conditions(illumination time varies from 0–24 h).We expected this system could provide new perspectives into spatiotemporal regulation of protein degradation and help realize the clinical application transformation for treating diseases of protein degradation technology. | Yafeng Hao Taofeng Du Gaoju Pang Jiahua Li Huizhuo Pan Yingying Zhang Lizhen Wang Jin Chang En-min Zhou Hanjie Wang | 2020 | Nano Research2020,13,12: | 0 |

| 8 | Effects of shrubs and precipitation on spatial-temporal variability of soil temperature in microhabitats induced by desert shrubs显示文摘Soil temperatures at 0, 5, 10 and 20 cm depths were monitored continuously at different microhabitats (beneath shrub canopy (BSC); bare intershrub spaces (BIS)) induced by xerophytic shrub (Caragana korshinskii Kom.) canopy, respectively. We mainly aimed to assess the effects of shrub canopy and precipitation on the spatial-temporal variability of soil temperature. Results indicate that both precipitation and vegetation canopy significantly affect soil temperature. In clear days, soil temperatures within the BSC area were significantly lower than in the BIS at the same soil depth due to shading effects of shrub canopy. Diurnal variations of soil temperature show a unimodal sinusoidal curve. The amplitude of soil temperature tended to decrease and a hysteresis of diurnal maximum soil temperature existed at deeper soil layers. Vertical fluctuations of soil temperature displayed four typical curves. In the nighttime (approximately from sunset to sunrise), surface temperature within the BSC area was higher than in the BIS. In rainy days, however, soil temperatures were affected mainly by precipitation and the shrub canopy had a negligible effect on soil temperature, and little difference in soil temperature at the same soil depth was found between the BSC area and in the BIS. Diurnal variations in soil temperature decreased exclusively as rainfall continued and the vertical fluctuations of soil temperature show an increased tendency with increasing soil depth. | YaFeng Zhang XinPing Wang Rui Hu YanXia Pan | 2013 | Research in Cold and Arid Regions2013,5,2: | 0 |

| 10 | A Simultaneous Car to on-Tex ture Image Segmentation and Image Decomposition Method显示文摘Image segmentation and image decomposition are fundamental problems in image processing.Image decomposition methods for separating images into cartoon and texture components can effec ti vely serve different image processing tasks because different components can be respectively treated in more effective way.However,image decomposition methods are currently simply taken as an independent preprocessing step,and particularly in image segmentation different effects of cartoon and texture components have not been considered.This paper presents a novel simultaneous cartoon・texture image segmentation and image decomposition method to boost the performance of both segmentation and decomposition.We design a fast alternating optimization algorithm to solve the proposed model.Experimental results demonstrate the outstanding performance of the proposed method on both image segmentation and image decomposition. | LI Yafeng ZHAO Qijun ZHANG Wenbo FAN Pan ZHANG Renrui SUN Jieqi LI Jing | 2020 | Chinese Journal of Electronics2020,29,5: | 0 |
| 11 | Intrastorm stemflow variability of a xerophytic shrub within a water-limited arid desert ecosystem of northern China显示文摘An increasing number of studies in recent years has elucidated distinguishable effects of stemflow on hydrology and biogeochemistry within a variety of ecosystems.Nonetheless,no known studies have investigated the temporal variability of stemflow volume within discrete rainfall events for xerophytic shrubs.Here,stemflow was monitored at 5-min intervals using a tipping-bucket rain gage during the 2015 growing season for a xerophytic shrub(Caragana korshinskii)within a water-limited arid desert ecosystem of northern China.We characterized the stemflow temporal variability,along with rainfall,and found the temporal heterogeneity of rainfall clearly affected the timing of stemflow inputs into basal soil within discrete rainfall events.The rainfall threshold value for stemflow generation is not a constant value but a range(0.6~2.1 mm,with an average of 1.1 mm)across rainfall events and is closely associated with the antecedent dry period.Time lags existed between the onset of rainfall and the onset of stemflow,and between rainfall peaks and stemflow peaks.Our findings are expected to be helpful for an improved process-based understanding of the temporal stemflow yield of xerophytic shrubs within water-limited arid desert ecosystems. | YaFeng Zhang XinPing Wang YanXia Pan Rui Hu | 2017 | Research in Cold and Arid Regions2017,9,5: | 0 |
| 12 | Variation in water source of sand-binding vegetation across a chronosequence of artificial desert revegetation in Northwest China显示文摘Water is the most important limiting factor in arid areas,and thus water resource management is critical for the health of dryland ecosystems.However,global climate change and anthropogenic activity make water resource management more difficult,and this situation may be particularly crucial for dryland restoration,because of variation in water uptake patterns associated with artificial revegetation of different ages and vegetation type.However,there is lacking longterm restorations that are suitable for studying this issue.In Shapotou area,Northwest China,artificial revegetation areas were planted several times beginning in 1956,and now form a chronosequence of sand-binding landscapes that are ideal for studying variability in water uptake source by plants over succession.The stable isotopesδ18O andδ2H were employed to investigate the water uptake patterns of the typical revegetation shrubs Artemisia ordosica and Caragana korshinskii,which were planted in different years.We compared the stable isotope ratios of shrub stem water to groundwater,precipitation,and soil water pools at five layers(5−10,10−40,40−80,80−150,and 150−300 cm).The results indicate that Artemisia ordosica derived the majority of their water from the 20−150 cm soil layer,whereas Caragana korshinskii obtained water from the 40−150 cm soil layer.The main water sources of Artemisia ordosica and C.korshinskii plants changed over time,from deeper about 150 cm depth to shallow 20 cm soil layer.This study can provide insights into water uptake patterns of major desert vegetation and thus water management of artificial ecosystems,at least in Northwest China. | YanXia Pan XinPing Wang Rui Hu YaFeng Zhang Yang Zhao | 2020 | Research in Cold and Arid Regions2020,12,5: | 0 |
| 13 | Observation of resistive switching in a graphite/hexagonal boron nitride/graphite heterostructure memristor显示文摘With the atomically sharp interface and stable switching channel, van der Waals(vdW) heterostructure memristors have attracted extensive interests for the application of high-density memory and neuromorphic computing. Here, we demonstrate a new type of vdW heterostructure memristor device by sandwiching a single-crystalline h-BN layer between two thin graphites. In such a device, a stable bipolar resistive switching(RS) behavior has been observed for the first time. We also characterize their switching performance, and observe an on/off ratio of >10^(3) and a minimum RESET voltage variation coefficient of3.81%. Our work underscores the potential of 2D materials and vdW heterostructures for emerging memory and neuromorphic applications. | Yafeng Deng Yixiang Li Pengfei Wang Shuang Wang Xuan Pan Dong Wang | 2022 | Journal of Semiconductors2022,43,5: | 0 |
