| 1 | Effects of 1-MCP on proline,polyamine,and nitric oxide metabolism in postharvest peach fruit under chilling stress显示文摘Peach(Prunus persica Batsch‘Yuhualu’)fruit are sensitive to chilling injury(CI).Proline,polyamine(PA),and nitric oxide(NO)are important small regulators of various metabolic pathways under chilling stress that mitigate CI.Ethylene is known to promote senescence and CI,while 1-methylcyclopropene(1-MCP)is an antagonist that inhibits the effects of ethylene.However,how1-MCP and ethylene affect proline,PA,and NO levels under chilling stress remains unclear.To address these questions,1-MCP(1μL·L^(−1))and ethylene(1μL·L^(−1))treatments were applied to peach fruit.Fruit were stored at 4°C for 28 d,then moved to 25°C for 3 d immediately after cold storage.Peach fruit exhibited CI symptoms after 7 d of cold storage with enhanced electrolyte leakage and malondialdehyde contents.The 1-MCP treatment significantly(P<0.05)restrained peach CI,and fruit did not exhibit CI symptoms until 14 d of cold storage.Proline and PAs in peach under chilling stress weremostly synthesized from glutamate and arginine,which were catalyzed by1-pyrroline-5-carboxylate synthetase and arginine decarboxylase,respectively.1-MCPtreated fruit exhibited higher proline and PA contents and enhanced chilling tolerance compared to the control,while ethylene-treated fruit had lower proline and PA contents and reduced chilling tolerance.Ethylene-treated fruit,which exhibited more severe CI symptoms compared to the control,had significantly(P<0.05)lower NO contents and NO synthase activities.However,NOmay not be a direct acting factor in 1-MCPinduced chilling tolerance,as 1-MCP-treated fruit had lower NO contents and NO synthase activities compared to the control.In conclusion,proline and PA clearly played direct and important roles in 1-MCP-induced peach chilling tolerance,while NO may not be actively involved. | Chunlu Qian Zhengjie Ji Qin Zhu Xiaohua Qi Qianqian Li Jiandong Yin Jun Liu Juan Kan Man Zhang Changhai Jin Lixia Xiao | 2021 | Horticultural Plant Journal2021,7,3: | 4 |
| 2 | DIV: Dynamic Integrity Validation Framework for Detecting Compromises on Virtual Machine Based Cloud Services in Real Time显示文摘with the increasing popularity of cloud services,attacks on the cloud infrastructure also increase dramatically.Especially,how to monitor the integrity of cloud execution environments is still a difficult task.In this paper,a real-time dynamic integrity validation(DIV) framework is proposed to monitor the integrity of virtual machine based execution environments in the cloud.DIV can detect the integrity of the whole architecture stack from the cloud servers up to the VM OS by extending the current trusted chain into virtual machine's architecture stack.DIV introduces a trusted third party(TTP) to collect the integrity information and detect remotely the integrity violations on VMs periodically to avoid the heavy involvement of cloud tenants and unnecessary information leakage of the cloud providers.To evaluate the effectiveness and efficiency of DIV framework,a prototype on KVM/QEMU is implemented,and extensive analysis and experimental evaluation are performed.Experimental results show that the DIV can efficiently validate the integrity of files and loaded programs in real-time,with minor performance overhead. | WANG Chunlu LIU Chuanyi LIU Bin DONG Yingfei | 2014 | China Communications2014,11,8: | 2 |

| 8 | Chemical grout diffusion in porous rock based on response of geoelectric feld显示文摘Porous rock chemical grouting simulation test was conducted using established large scale physical model.Chemical grout diffusing rule in porous media with different permeability was studied by monitoring the spontaneous potential and exciting current response during grouting.The results show that chemical grout spread evenly in all directions and diffusion areas are approximately concentric circles in the cross section of homogeneous transverse isotropic pore medium,the grout spread flling range can be quantitatively decrypted by the diffusion radius.The average diffusion speed and radius increase approximately as the square root with the permeability coeffcient in different permeability media under the same conditions.Calculation results using Maag cylindrical diffusion equation show that the calculated value of diffusion radius is in good agreement with the test value under different grouting pressures and permeability conditions. | Jiang Chunlu Jiang Zhenquan Liu Shengdong Sun Qiang Yang Cai | 2013 | International Journal of Mining Science and Technology2013,23,5: | 1 |

| 12 | A possible endoscopic therapy for large hiatal hernia complicated with refractory gastroesophageal reflux disease显示文摘A hiatal hernia(HH)is usually associated with gastroesophageal reflux disease(GERD).An HH can increase the incidence of GERD.[1]The coexistence of these diseases increases the difficulty of treatment and can be challenging for endoscopic treatment.Therapeutic methods for small HHs(≤2 cm)combined with refractory GERD have recently been emerging.However,there are still knowledge gaps in the endoscopic treatment of large HHs(≥3cm)combined with refractory GERD.We developed a new endoscopic method called hiatal hernia-endoscopic submucosal dissection(HH-ESD)and performed the present study to clarify the efficacy and safety of HH-ESD. | Haijing Zhang Haiping Zhao Mingxing Hou Chunlu Jin Rui Rui Baiyinbatu Xie Ying Li Zhiguang Hu Guanlan Liu Feng Guo Haiqing Hu | 2022 | Chinese Medical Journal2022,,8: | 1 |

| 14 | Dielectric properties of edible fungi powder related to radio-frequency and microwave drying显示文摘Edible fungi are rich in nutrition,but they are susceptible to spoilage,and often prolonged by drying.RF and microwave energy drying have the advantages of short drying time,high energy efficiency and good process control.However,to develop an effective dielectric drying method,it is important to understand dielectric properties,the major factor characterizing the interaction between the electromagnetic energy and the food.At present,there is a lack of research on dielectric properties of edible fungi.In this study,a vector network analyzer and an open-ended coaxial-line probe were employed to measure the dielectric parameters.The dielectric parameters were observed at different temperatures(25–85°C)for edible fungi powder with moisture content ranging from 5 to 30%wet basis over a frequency range of 1–3000 MHz.The relationship between the dielectric properties and frequency,temperature,and moisture content were obtained via regression analysis.Further,the dielectric penetration depth was calculated,and the effects of frequency,moisture content,and temperature on the penetration depth were also analyzed.The results showed that the dielectric properties of edible fungi powder increased with an increase in moisture content and temperature,while they decreased with increasing frequency.At high moisture content and temperature,the increase in dielectric properties was slightly larger than that at low moisture content and temperature.The dielectric properties changed more evidently at lower radio frequencies than at higher radio frequencies.The penetration depth decreased with an increase in temperature,moisture content,and frequency.It can be concluded that a large penetration depth at radio frequencies below 100 MHz could be used to dry edible fungi on a large scale,whereas microwave energy could be employed for drying edible fungi on a small scale. | Siying Qi Jiping Han Camel Lagnika Ning Jiang Chunlu Qian Chunquan Liu Dajing Li Yang Tao Zhifang Yu Libin Wang Zhongyuan Zhang Chunju Liu Yadong Xiao Min Zhang | 2021 | Food Production, Processing and Nutrition2021,3,1: | 0 |
| 15 | Experimental Testing of Greenhouse-Integrated Vanadium-Titanium Black Ceramic Solar Absorbers显示文摘As a solution for solar heating, the low-cost and long-life vanadium-titanium black ceramic solar absorbers have been used in rural construction. However, in contrast to its high absorptance(0.93-0.97), ceramic also has high emissivity(approximately 90%) and low thermal conductivity(1.3 W/(m·K)). Without a glaze covering, ceramic absorbers cannot meet the industrial standard. This paper assumes that glaze covering can be substituted by insulation film in a solar greenhouse. To verify this assumption, field experiments were conducted. First, a traditional greenhouse in the Tacheng Basin, a severely cold area in China, was renovated to improve its passive thermal performance. Then, 90 m^(2) of ceramic absorbers and floor coils as well as a water tank were installed inside the greenhouse, which made the entire construction act as an integrated solar collector. This heat collection and release system moderately increased the indoor air temperature(0.9℃-22.4℃) and substantially increased the soil temperature(15.5℃-31.2℃). The average daily useful heat gain under a daily solar insolation value of 17 MJ/m^(2) was 13.8 MJ, and the mean value of the collection efficiency was 0.81. Furthermore, the payback time of the project(7 years) is short, which is principally due to the low cost of ceramic materials and the financial savings of the shared construction components(e.g., transparent cover, metal frame and extra insulation). In conclusion, the main contribution of this study is the verification that it is feasible to replace glaze covering with insulation film in a novel greenhouse-integrated vanadium-titanium black ceramic solar system. | DING Ding LIU Chunlu WANG Qichun ZHAO Zhibin XU Jianhua CAO Shuliang | 2022 | Journal of Thermal Science2022,31,6: | 0 |
| 16 | On-site solar PV generation and use: Self-consumption andself-sufficiency显示文摘As energy storage systems are typically not installed with residential solar photovoltaic (PV) systems,any “excess” solar energy exceeding the house load remains unharvested or is exported to the grid.This paper introduces an approach towards a system design for improved PV self-consumptionand self-sufficiency. As a result, a polyvalent heat pump, offering heating, cooling and domestic hotwater, is considered alongside water storage tanks and batteries. Our method of system analysisbegins with annual hourly thermal loads for heating and cooling a typical Australian house inGeelong, Victoria. These hourly heating and cooling loads are determined using Transient SystemSimulation (TRNSYS) software. The house’s annual hourly electricity consumption is analysed usingsmart meter data downloaded from the power supplier and PV generation data measured with aPV system controller. The results reveal that the proposed system could increase PV self-consumptionand self-sufficiency to 41.96% and 86.34%, respectively, resulting in the annual imported energybeing reduced by about 74%. The paper also provides sensitivity analyses for the hot and coldstorage tank sizes, the coefficient of performance of the heat pump, solar PV and battery sizes.After establishing the limits of thermal storage size, a significant impact on self-efficiency can berealised through battery storage. This study demonstrates the feasibility of using a polyvalent heatpump together with water storage tanks and, ultimately, batteries to increase PV self-consumptionand self-sufficiency. Future work will concentrate on determining a best-fit approach to systemsizing embedded within the TRNSYS simulation tool. | Zheng Wang Mark B.Luther Peter Horan Jane Matthews Chunlu Liu | 2023 | Building Simulation2023,16,10: | 0 |
