Abstract： Background In the face of the serious challenges posed by the high prevalence of chronic diseases among the elderly and the coexistence of multiple chronic diseases，the health problems of community-dwelling elderly people' with multimorbidity require urgent attention. The comorbidity management model is being explored and practiced. Disease experience，as self-reported health information from patients，is expected to become a key component of the patient-centered community multimorbidity management model. Objective This study aimed to gain a deeper understanding of the real disease experience of community-dwelling elderly people with multimorbidity and provide a basis for personalized health management and supportive strategies of the group. Methods This study used purposive sampling and maximum difference sampling to select eligible interviewees from four communities under the jurisdiction of a community health service center in Zhengzhou City from August to September in 2022. Based on the principle of information saturation，20 subjects were ultimately included. Based on the research objective，literature review，and expert consultation results，the preliminary interview outline was formulated， and the final interview outline was determined after interviewing 2 patients. Semi-structured interviews were conducted with the study participants，guided by the phenomenological research methodology. Golaizzi analysis was used to analyse the data. Results Four themes and eleven sub-themes had been extracted from this study，including mainly long-standing symptomatic distress（physical dysfunction，fatigue，sleep disorders，and pain），negative psychological experiences （feelings of helplessness and worry about future life，reduced sense of social value and self-identity，and loneliness with altered social activities）， positive mindset of coexisting harmoniously with multimorbidity（being grateful for being satisfied，and positively adapting）， and aspirations in times of adversity（hoping for improvement in functioning，and seeking multi-directional social support）. Conclusion Physical dysfunction，sleep disturbances，fatigue，and pain are the most concerning health disturbances for community-dwelling elderly people with multimorbidity. The symptom management and multiple social support of the multimorbidity need to be strengthened. In the future，it is expected that multidimensional data would be used for dynamic health assessment to explore the common and individual patterns of multimorbidity，and to achieve precise management and intervention of elderly multimorbidity in the community.

Abstract： The diagnosis and treatment of disorder of consciousness（DOC）is still challenging. One of the neural mechanisms of DOC is the destruction of synchronization and connectivity of neural oscillation. This article will review the progress of neural oscillation in the diagnosis and treatment of DOC from three aspects：theoretical basis，application progress，and existing deficiencies of neural oscillations applied to DOC. Neural oscillation is the periodic and synchronous activity of neurons under certain conditions. There are obvious differences in the spectrum characteristics，phase synchronization，and response to neural regulation of neural oscillations among different severities of DOC. The analysis of neural oscillation based on electroencephalography（EEG）reveals the information transmission and processing ability at different levels of consciousness，which is helpful to distinguish different degrees of DOC more accurately and achieve the purpose of DOC wakening treatment by regulating neuro oscillation. Despite there being some problems like insufficient mechanism studies and slow application transformation，neural oscillation has shown great application potential in the diagnosis and treatment of DOC.

Abstract： In order to adjust the structure of inefficient Pinus massoniana forest and explore the dynamic changes for DOC during the mixed decomposition process of P. massoniana and native broad-leaved tree species. Our research focuses on the leaf litter of P. massoniana, Cinnamomum camphora and Toona sinensi, and combine them into the 15 treatments (3 single tree treatments + 12 mixed treatments) according to different tree species combinations and mass ratios, and then conducted field decomposition experiments to further explore the optimal combination for DOC release. The results showed that: (1) DOC content of Pinus massoniana and most of mixed treatments (except for PT64) significantly increased during the early stages of decomposition (0-6 months), leading to carbon enrichment. The DOC content of leaf litter decreased with the extension of decomposition time, and also exhibit carbon enrichment in small degree during the middle to late stages of decomposition (12-18 months) or the late stages of decomposition (18-24 months). Mixed leaf litter showed that the higher the proportion of broad leaves, the lower the DOC content in the later stage. (2) The antagonistic effect of DOC release rate in the early stage of decomposition (0-6 months) was strong (58.33%), and its synergistic effect gradually strengthened (91.67%) after 6-18 months. But the synergistic effect of leaf litter weakened (66.67%) during the late stage of decomposition (18-24 months). Among all mixed treatments, PT64 exhibited synergistic effects throughout the entire decomposition period, followed by PT73, PCT622 and PCT613(3/4). (3) Partial Least-Squares Regression (PLS) showed that N content, P content, lignin content, condensed tannin content, C/N, C/N, lignin/N, and lignin/P were important factors affecting the release of DOC from litter in this study area. Overall, the DOC release from mixed P. massoniana and broad-leaved litter was affected by tree species, mixing ratio and decomposition time. Among all of the mixtures, PT64, PT73, PCT622 and PCT613 showed strong synergistic effects for DOC release.

Abstract： To reduce the weight of car body, Al-Mg-Si-Cu alloys have been widely used to produce outer body panels of automobiles due to their favorable high strength-to-weight ratio, corrosion resistance, weldability and good formability. Al- Mg- Si- Cu alloys belong to age- hardenable aluminium alloys, whose strength derives mainly from the matrix precipitation during aging treatments. However, their bake hardening response still need to be further improved to enhance their dent resistance. A novel thermo-mechanical treatment consisting of conventional pre-aging, pre-deformation and re-aging was developed to enhance the tensile properties and bake hardening increment of Al-Mg-Si-Cu alloys. In this work, the effect of pre-deformation on the precipitation behaviors of Al-Mg-Si-Cu alloy was studied by DSC, mechanical property measurement and TEM. The results show that, the GPzone dissolution rate decreases with increasing pre-deformation during the slow heating up process for the pre-aged alloy, the corresponding activation energies of 0, 5% and 15% pre-deformed alloy calculated by Avrami-Johnson-Mehl method are 137.1, 189.5 and 141.3 kJ/mol, respectively. If the pre-deformed alloys are directly bake hardened at 185 ℃ for 20 min, precipitation and bake hardening increment can be greatly improved by pre-deformation (the highest bake hardening increment is 160 MPa), but the bake hardening increment rate gradually decreases if the pre- deformation is above 10%. In addition, the GP zone dissolution rates of pre- deformed alloys after bake hardening treatment are much lower when the heat treatment temperatures are below one certain value, but if the treatment temperatures above it, the corresponding GP zone dissolution rates are higher than that of alloy without pre-deformation, finally, the activation energy changes from high value to low value even can be observed in the ln[(dY/dT)f/f(Y)]-1/T curve. For the β″ precipitation in the alloys, with increasing pre-deformation, its activation energy gradually decreases, corresponding gradually increase of precipitation rate.

Abstract： To reduce the weight of car body, Al-Mg-Si-Cu alloys are becoming increasingly attractive as a candidate for material substitution used to produce the outer body panels of automobiles because of their favorable bake-hardening response. However, the formability still needs to be further improved compared to steels. In this work, the effect of the thermomechanical processing on the mechanical properties and microstructure of Al-Mg-Si-Cu alloy is studied through tensile test, OM, SEM and TEM observation, as well as EBSD characterization. The results reveal that there is almost no change in both strengths and strain-hardening exponent n of the sheets in T4P condition after different thermomechanical processing, but the average plasticity strain ratio r, planar anisotropy Δr and elongations in the three directions show obvious differences. The sheet undergone hot rolling, cold rolling, intermediate annealing, cold rolling and solution (processing II) has a better formability (r= 0.6187) and a weaker planar anisotropy than that subjected to hot rolling, intermediate annealing and then cold rolling before solution treatment (processing I). Although the particle stimulated nucleation (PSN) effect of processing I is remarkable during solution treatment, due to the appropriate controlling cold deformation and distribution of second-phase particles with different sizes in processing II, most of the recrystallization grains are equiaxial and the recrystallization texture is only consisted of CubeND, Cube and H with a low intensity. At last, according to the relationship between the microstructure and the thermomechanical processing, the microstructure evolution model during different thermomechanical processes is established.

Abstract： Aiming at the security problems existing in the process of the data aggregation and transmission in crowd sensing networks, such as privacy leakage, incomplete information, data tampering. this paper proposed a data aggregation privacy protection algorithm based on distributed compressive sensing and hash function. Firstly, it used distributed compressive sensing method to sparsely observe the sensed data and remove the redundant data. Then, it utilized one-way hash function to obtain hash value of the observation data and filled the hash value with the unconstrained camouflage data into the observation data of sensory data to reach the aim of concealing the true sensor data. Finally, after extracting the camouflage data at the sink node, it obtained the hash value of the observation data again to verify the integrity of data. Simulation results show that the algorithm takes into account the privacy preserving and integrity protecting of data, and also can reduce the communication overhead greatly, which means the strong applicability and scalability in practical applications.

Abstract： The existing privacy protection strategies in crowd sensing networks used the same privacy policies for all locations which overprotected led to the problems that some locations, others were not adequately protected and the sensing data was less accurate. In order to solve this problem, this paper proposed a location privacy protection algorithm to meet the users’ personalized privacy and security requirements. First, it mined users’ access duration, frequency and regularity at different locations according to the user's historical movement trajectory, which used to predict the social attributes of the locations to the users. Then, it combined the location’s social attributes and natural attributes to predict user-location sensitivity levels. Finally, considering the different privacy security requirements of users in different locations, it set a dynamic privacy decision scheme. Users with less sensitivity at each location were selected to participate in sensing tasks to ensure that users, in the safe privacy context, could contribute the accurate data with a higher level of spatiotemporal correlation. The simulation results show that the algorithm can improve the privacy protection level and the accuracy of the sensing data.

Abstract： Objective To construct a recombinant lentiviral vector that co-express green fluorescent protein (GFP) and FoxM1 shRNA and establish a prostate cancer cell line with stable FoxM1 down-regulation. Methods Three interfering sequences targeting FoxM1 were designed and inserted into the lentiviral vector pHBLV-U6-ZsGreen-Puro. After identification by DNA sequencing, the lentiviral vectors carrying Foxm1 shRNA were packaged in 293 cells. The lentiviral particles were collected to infect human prostate cancer DU-145 cells, and the transfection efficiency was observed under fluorescence microscope; the interference efficiency was assessed using real-time PCR. DU-145 cells with stable FoxM1 down-regulation were screened with puromycin, and the expression level of FoxM1 was detected by Western blotting and the cell growth was observed using MTT assay. The stably transfected cells were examined for cell apoptosis and cell clone formation capacity with flow cytometry and colony formation assay. Results DNA sequencing demonstrated successful construction of the 3 FoxM1 shRNA lentivirus vectors. Real-time PCR showed a high interference efficiency of FoxM1 shRNA1 vector, which resulted in obvious down-regulation of FoxM1 in DU-145 cells. Western blotting showed that the expression of FoxM1 protein was decreased in FoxM1 shRNA1 lentivirus-transfected cells, which displayed a suppressed cell proliferation, increased apoptosis rate, and attenuated clonogenic ability. Conclusion We have successfully established a prostate cancer cell model with stable FoxM1 down-regulation, which shows lowered proliferative and clonogenic activities with increased cell apoptosis.

Abstract：通过弯边变形、拉伸实验、OM、SEM、TEM观察等手段研究了不同浓度富铁相粒子对Al-Mg-Si-Cu系合金板材弯边性能的影响规律。结果表明，随着富铁相浓度增加，合金板材沿纵横向的弯边性能存在较大差异，不含富铁相粒子的合金板材沿两个方向弯边变形180°后外表面粗糙度增加，处于中等浓度（含0.2wt%Fe）时沿两个方向弯边变形后均具有优异的外表面质量，但是随着富铁相浓度的进一步增加（至0.5wt%Fe），合金板材沿两个方向弯边变形后均在外表面出现微裂纹。虽然富铁相粒子浓度增加对合金板材纵横向延伸率影响不大，但是拉伸断口、弯边和拉伸断裂后的侧表面组织均表明，不含富铁相的合金板材弯边变形后外表面粗糙度增加与剪切带组织密切相关，而含有较高浓度富铁相粒子的合金板材弯边变形后外表面出现的微裂纹与粗大富铁相粒子的尺寸、形态以及分布状态密切相关。此外，本文根据不同浓度富铁相粒子与合金弯边性能间的定量关系提出了合金弯边变形后外表面粗糙度增加和微裂纹形成的模型示意图。

Abstract：采用DSC、力学性能测试及TEM研究了预变形对Al-Mg-Si-Cu合金析出行为的影响。结果表明，预时效态合金在慢速率升温过程中，GP区溶解速率均随预变形量的增加而降低，利用Avrami-Johnson-Mehl方法求得经0%、5%和15%预变形后合金的GP区溶解激活能分别为137.1KJ/mol、189.5KJ/mol和141.3KJ/mol；若合金经不同预变形后直接进行185℃/20min烤漆硬化，预变形可有效促进沉淀相析出，提高烤漆硬化增量，最高达160MPa，不过预变形量大于10%时合金烤漆硬化增幅减缓；此外，经预变形处理后烤漆态合金的GP区溶解速率在一定温度下均较低，但高于某一温度后，相应的GP区溶解速率均高于未经预变形处理的，最终获得的ln[(dY/dT)φ/f(Y)]-1/T曲线甚至会出现高激活能向低激活能转化现象；不过随预变形量增加，β〃相析出激活能不断降低，析出速率不断增加，相应的TEM组织观察结果与此非常吻合。
