Abstract： In thermonuclear reactions of nuclear astrophysical interest, some can produce short-lived products that emit positrons. The positrons emitted by these products will annihilate with electrons in the target and then produce a pair of 511 keV γ-rays, which can be used to determine the reaction yield and calculate the cross-section as well as the astrophysical S-factor. Recently, it has been found that the spatial coincidence measurements can be performed basing on the opposite direction of the 511 keV-511 keV γ-ray pair, which can reduce the natural background and enables the in situ measurement of the reaction yield using activity method. In this paper, based on the recently developed large modular BGO detector array LAMBDA-II, this method has been investigated and validated in the ground laboratory, which provides good basis for further application of this method in the nuclear astrophysical investigations in the future.

Abstract： Background Telerehabilitation based on digital medical care can efficiently improve the health status of patients after radiofrequency ablation of atrial fibrillation. However，the current participation rate in telerehabilitation is low. Objective To analyse the reasons for refusal of exercise rehabilitation in patients after radiofrequency ablation of atrial fibrillation in the context digital medical care based on the theory of leisure constraints. Methods Patients after radiofrequency ablation of atrial fibrillation in the inpatient department or outpatient clinic of cardiology at a tertiary-level hospital in Jiangsu Province from July 2022 to September 2022 were selected as the study subjects by using the purposive sampling method. The phenomenological approach was adopted to collect data from patients who refused exercise telerehabilitation after radiofrequency ablation through semi-structured interviews，and Colaizzi analysis was used to summarize the reasons. Results A total of 14 patients were finally included in this study. Three themes including self-limiting factors，interpersonal limiting factors，and structural limiting factors，and twelve sub-themes were extracted，namely，low level of digital literacy，negative illness perception，psychological distress caused by disease，digital medical trust crisis，deep-rooted personal exercise habits，alienation sense from rehabilitation team，insufficient social network establishment，economic burden related to equipment acquisition，harsh climate，low rehabilitation service capacity in primary care，constraints of available time by role pressure，and poor applicability of wearable devices. Conclusions The reasons for refusal to exercise telerehabilitation include lack of literacy and trust in digital medical care，high level of illness perception and psychological distress，poor exercise habits，rehabilitation team and peer alienation，economic burden，harsh climate，lack of capacity and personal time for rehabilitation service capacity in primary care，and inadequate applicability of existing wearable devices. It is necessary to build an effective support system and social network in exercise telerehabilitation on the basis of strengthening digital literacy and promoting mental recovery of patients in the future，strengthen the construction of the rehabilitation team to meet the requirements of digital medical care context，improve the treatment-rehabilitation-long-term care service chain centered on smart health and the reinforcement of rehabilitation service configuration in primary care，which is helpful to promote the participation of patients after radiofrequency ablation of atrial fibrillation in exercise telerehabilitation.

Abstract： To explore ground reaction forces(GRF)characteristic values among runners with different foot strike patterns(FSP),and then analyze GRF-time series data based on one-dimensional statistical parametric mapping(SPM),32 habitual rearfoot strike pattern(RFS)runners and 27 habitual non-rearfoot strike pattern(NRFS)runners were included in our study.Kistler force plates were used to collect GRF data when participants were running on rubber at a speed of 12 km/h.SPM was used to analyze the differences of GRF-time series data among runners with different FSP.GRF characteristic values demonstrated that vertical average loading rate and anterior-posterior GRF of RFS runners were significantly higher than those of NRFS runners.The SPM results found that compared with NRFS runners,RFS runners have significantly higher GRF during 5%-10% and lower GRF during 4%-12% of the stance phase in anterior-posterior and medial-lateral direction.RFS runners have significantly lower GRF during 0-3% and higher GRF during 8%-14% of the stance phase in vertical direction.The results of GRF characteristic values and SPM GRF-time series data suggested that traditional characteristic values analysis seems insufficient to represent actual biomechanical characteristics of lower limbs,continuity hypothesis test like SPM should be established to better describe biomechanical parameters-times series data,thus providing constructive suggestions for the prevention of running injuries.

Abstract： Beijing-Tianjin-Hebei region, Yangtze River Delta, and Guangdong-Hong Kong-Macao Greater Bay Area are the three largest urban agglomerations in China, and have been increasingly becoming the core engines of China’s economic growth. Nevertheless, rapid regional urbanization accompanying high-intensity human activities has also brought enormous social and environmental pressure in these urban agglomerations, posing a grand challenge to urban and regional sustainability. This study conducts a cross-urban agglomeration comparison of the ecological and environmental changes over the past two decades. Using a combination of remotely sensed data, in-situ monitoring data, and environmental statistic data, the changes in four dimensions are quantified, namely ecological quality, environmental quality, resource and energy use efficiency, and eco-environmental governance capacity. Further, the effectiveness of environmental policies and initiatives is evaluated at the national and urban agglomeration levels. It is found that the quality of ecological land has increased steadily since 2000, with increased provision of ecosystem services. Air quality and water quality have been substantially improved, and the use of resources and energy efficiency have been greatly improved. The pollution emissions per unit GDP have been greatly reduced. The ecological and environmental infrastructures have become increasingly available, along with gradually strengthened governance capacity on environmental protection and ecological restoration. The National 10th to 13th Five-Year Plan for Environmental Protection played a significant role in environmental protection and ecological restoration across mega urban agglomerations. The environmental challenges, of urban agglomerations faced now and in the future, are also discussed, so as to the policies and actions that need to be addressed.

Abstract： Legacy motivation refers to the phenomenon that individuals want to leave a mark on this planet and be remembered by others for a long time. It is a fundamental motivation that has been widely possessed by human beings. It can have important psychological and behavioral consequences because it offers individuals an enduring meaning for self-identity and motivates them to extend themselves into the future. Previous work examined the influences of legacy motivation in the domains of intergenerational decision making and employee behaviors. However, research on how legacy motivation influences individuals' other behaviors remains in infancy. The current work takes a novel perspective and focuses on the influence of legacy motivation in the domain of financial decision making. We examine how and why legacy motivation affects individuals' risk- taking behavior and when it occurs. We propose that legacy motivation would diminish individuals' tendency to engage in risk-taking behavior. This effect is driven by future self-continuity perception and occurs among people with a high socioeconomic status (SES). Four experiments were conducted to test our proposed hypothesis. Study 1 was designed to offer initial evidence that legacy motivation would lead to a greater perception of future self-continuity. This study employed a one factor (legacy motivation: legacy vs. control) between-subject design and manipulated legacy motivation by asking participants to write an essay on what they wanted to be remembered for by future others. In the control condition, participants were instructed to imagine and write about what life would be in 30 years. Study 2a established the main effect of legacy motivation on individuals' risk-taking tendency. Participants were presented a job recruitment advertisement featuring a high wage but low job security to measure their risk-taking tendency. They indicated their likelihood of adopting this new job. Study 2b replicated the effect of legacy motivation on risk-taking behavior and explored the underlying mechanism of future self-continuity. Risk-taking behavior was operationalized by asking participants to select one of three financial portfolio products that represent different degrees of financial risk. Study 3 investigated the moderation role of individuals' SES. A 2 (legacy motivation: legacy vs. control) � 2 (SES: continuous variable) design was employed, in which legacy motivation was manipulated, and SES was measured. The propositions were supported by several convergent results. Study 1 provided initial evidence that activating legacy motivation would result in a higher future self-continuity perception (Mlegacy = 4.25, SD = 1.50, Mcontrol = 3.81, SD = 1.44; F(1, 182) = 4.08, p = 0.045, Cohen's d = 0.30). Study 2a documented the main effect by showing that legacy motivation weakened individuals' likelihood of engaging in financial risk taking (Mlegacy = 4.22, SD = 1.84, Mcontrol = 4.66, SD = 1.72; F(1, 259) = 4.09, p = 0.044, Cohen's d = 0.25) and ruled out several alternative interpretations such as self-esteem, mood, and impression management. Study 2b confirmed the mediation role of future self-continuity in driving legacy motivation's effect on financial risk taking (b = 0.12, SE = 0.06, 95% CI = 0.03~0.26). Study 3 investigated the moderating role of participants' SES. We found that the legacy effect on financial risk taking as a function of future self-continuity only existed in participants with a relatively high SES (b = 0.19, SE = 0.08, 95% CI = 0.05~0.37) and disappeared with a relatively low SES (b = 0.03, SE = 0.05, 95% CI = -0.04~0.15). This study contributes to the literature on legacy motivation, future self-continuity, and financial risk-taking behavior. It extends the research on legacy motivation by documenting an important behavioral consequence in the domain of individual financial decision making. It also provides a new antecedent for future self-continuity and financial risk-taking behavior.

Abstract： Aesthetic is the first medium of a product in the era of “appearance economy.” Previous studies have explored the effects of aesthetic elements on consumer behavior, including color, packaging transparency, size, logo shape, and so on. Unlike existing studies, this research discusses the overall dimension of design, that is, the degree of complexity of the design. Specifically, we propose that people’s subjective social status affects their preference for complexity in design. Meanwhile, people with low social status are more likely to prefer a complex packaging design than those with high social status. We conducted five experiments to test the hypotheses. Experiment 1 used 2 (social status: low vs. high) × 2 (product design: simple vs. complex) between-subjects design with 198 adults (female = 128) participating in the experiment. The results showed that people with relatively low social status have higher evaluations of complex packaging designs (vs. simple designs). At the same time, the level of complexity did not influence how people with high social status evaluate products. Using a more rigorous method to manipulate the social status, Experiment 2 employed a one-factor two-level (social status: low vs. high) between-subjects design with 134 adults (female = 97). After manipulating social statuses, participants reported their preferences between complex and simple packaging designs. The result confirmed that people with low social status prefer products with complex designs (vs. simple designs). Similar to Experiment 2, Experiment 3 (211 participants, female = 151) also used a one-way design (social status: low vs. high vs. control) but added a control group as the baseline group for comparison. The results confirmed that a low social status could drive preference for complexity. Furthermore, the results showed that people with low social status prefer complex packing design more than those in control and high social status groups. At the same time, no significant difference was observed in the preference between the high social status and control groups. Experiment 3 also found that consumers’ perceived effort mediated the above effect. Specifically, low social status individuals (vs. individuals in high social status vs. individuals in the control group) perceived that complex packing products entailed more effort from producers. Hence, they preferred such products. Experiment 4 was a pre-registration experiment (200 participants, female = 151). The experimental design and procedure were the same as in Experiment 2. The results also showed that people with low social status preferred complex packaging designs and believed these products had a higher value. Compared with high social status individuals, low social status individuals perceived that producers spent more effort on a product if it had a complex packaging design. Thus, these consumers perceived higher product value, as well as higher preference toward the product (sequential mediation: model 6). Experiment 5 tested the mediation effect by moderators. We proposed that the impact of social status only existed in consumers who believed in the value of effort. Experiment 5 used a 2 (social status: low vs. high) × 2 (product design: simple vs. complex) × 2 (belief in effort value: low vs. high) between-subjects design (346 participants, female = 208). The ANOVA revealed a three-way interaction. Furthermore, the Johnson-Neyman analysis found that the preference for complex design among low social status individuals only existed among those who believed in the value of effort. The results of this interaction again suggested that the preference of low social status individuals for complexity stems from their perception of the producer’s effort in making these products. This study has the following theoretical contributions. First, it brings the perspective of subjective social status to the study of consumer aesthetics. Second, it provides a new mechanism for the role of social status, i.e., social status affects people’s behavior by influencing their perceived importance of effort. Previous explanations of the behavior of low social status individuals have tended to be from a compensatory psychological perspective. In contrast, the current research takes the perspective of effort to demonstrate that low social status individuals value effort, which influences their behavior. Third, this research also contributes to the study of consumer effort, as this study finds that simply changing the level of complexity of packaging design can change people’s perceptions of producer effort.

Abstract： With the rapid development of economy and people's living standards, people's demands for crops have changed from quantity to quality. The rise and rapid development of remote sensing technology provides an effective method for crop monitoring. Accurately predicting wheat quality before harvest is highly desirable to optimize management for farmers, grading harvest and categorized storage for the enterprise, future trading price, and policy planning. In this research, the main producing areas of winter wheat (Henan, Shandong, Hebei, Anhui and Jiangsu provinces) were chosed as the research areas, with collected 898 samples of winter wheat over growing seasons of 2008, 2009 and 2019. A Hierarchical Linear model (HLM) for estimating grain protein content (GPC) of winter wheat at heading-flowering stage was constructed to estimate the GPC of winter wheat in 2019 by using meteorological factors, remote sensing imagery and gluten type of winter wheat, where remote sensing data and gluten type were input variables at the first level of HLM and the meteorological data was used as the second level of HLM. To solve the problem of deviation in interannual and spatial expansion of GPC estimation model, maximum values of Enhanced Vegetation Index (EVI) from April to May calculated by moderate-resolution-imaging spectroradiometer were computed to represent the crop growth status and used in the GPC estimation model. Critical meteorological factors (temperature, precipitation, radiation) and their combinations for GPS estimation were compared and the best estimation model was used in this study. The results showed that the accuracy of GPC considering three meteorological factors performed higher accuracy (Calibrated set: R2 = 0.39, RMSE = 1.04%; Verification set: R2 = 0.43, RMSE = 0.94%) than the others GPC model with two meteorological factors or single meteorological factor. Therefore, three meteorological factors were used as input variables to build a winter wheat GPC forecast model for the regional winter wheat GPC forecast in this research. The GPC estimation model was applied to the GPC remote sensing estimation of the main winter wheat-producing areas, and the GPC prediction map of the main winter wheat producing areas in 2019 was obtained, which could obtain the distribution of winter wheat quality in the Huang-Huai-Hai region. The results of this study could provide data support for subsequent wheat planting regionalization to achieve green, highyield, high-quality and efficient grain production.

Abstract： The difference of survival response of plants at different levels in evergreen broadleaved forest to the Phyllostachys edulis expansion were explained from the perspective of ecological stoichiometry homeostasis. Using the method of space-time substitution, a typical P. edulis evergreen broadleaved forest interface including P. edulis forest, P. edulis broadleaved mixed forest and evergreen broadleaved forest was selected in Jinggangshan National Nature Reserve, Jiangxi Province. The N and P content of soil and leaves of P. edulis, broadleaved trees, shrubs and herbaceous plants in each forest were compared and analyzed. (1) From bamboo forest to evergreen broadleaved forest, the soil N content and N:P ratio increased, while soil P content decreased; the leaves P content of tree species Machilus thunbergii, Alniphyllum fortunei and Daphniphyllum macropodum decreased and the N:P ration increased. Unlike the trees, the leaf N and P stoichiometry characteristic of plants both in shrub and herbaceous layers showed no significant changes, except the shrub tree Lindera erythrocarpa. (2) The soil N:P ration was positively correlated with the leaf N:P of trees, negatively correlated with that of shrubs and had no correlations with that of herbaceous plants, respectively. (3) The leaves N and P content and N:P ratio for P. edulis remained stable.P. edulis expansion changes plant leaf N and P stoichiometry characteristic by altering the soil N and P stoichiometry characteristic. Shrubs and herbaceous plants are less affected, however, it caused the imbalance of plants N and P stoichiometry characteristic of tree layer plants, which may be an important reason for the death of tree species in the evergreen broadleaved forest.

Abstract： Nerium indicum is an important medicinal plant. In order to study the diversity of endophytic fungi from N. indicum and evaluate the activity of its secondary metabolites, the endophytic fungi of N. indicum in Guangxi were isolated and purified, and identified by a combination of morphology and ITS sequence analysis. Then the antibacterial activity of endophytic fungus extracts were screened with 5 indicator bacteria (including 3 Vibrio species). The results showed that: (1) A total of 19 endophytic fungi were obtained from Guangxi N. indicum. The ITS sequence analysis showed that these 19 endophytic fungi all belonged to the Ascomycota, and covered 5 orders and 7 genera, which including Colletotrichum, Guignardia, Phyllosticta, Neofusicoccum, Aspergillus, Nothophoma and Diaporthe. Among them, the dominant genera were Colletotrichum (the separation rate was 36.85%) and Guignardia(the isolation rate was 21.05%). The Colletotrichum was mainly distributed on stems, and Guignardia all originated from leaves. (2) Antibacterial experiments showed that: jing-117 (Neofusicoccum sp.) and ye-130 (Guignardia sp.) had specific antibacterial effects on Vibrio campbellii. ye-136 (Aspergillus sp.) can simultaneously inhibited Bacillus subtilis and Vibrio campbellii. ye-135 (Aspergillus sp.) and jing-116 (Colletotrichum sp.) can only inhibited Bacillus subtilis. ye-134 (Guignardia sp.) had an inhibitory activity to Vibrio alginolyticus. The study revealed for the first time that endophytic fungi of Nerium indicum in Guangxi has a relatively rich diversity based on the ITS sequence. Some antibacterial active strains could be screened, and their extracts could inhibit the growth of aquatic pathogen Vibrio, which will has good development value in the future.

Abstract： Developmental motor disorders are the common feature of autism spectrum disorder (ASD). Through a systematic review of the neuroscience literature, it is found that the alteration in the concentration of GABA and of serotonin and the abnormal expression of GABA-related protein and of shank protein led to not only the defects of the development of the central nervous system but also the synaptic excitation/inhibition imbalance, thus in turn resulting in the changes of the functional connectivity between cerebellum and motor cortex in children with ASD. The abnormalities in the structure of the cerebellum, basal ganglia, and corpus callosum had a negative impact on the whole-brain connectivity in children with ASD. The disorders in neurobiochemical mechanisms and the abnormalities of brain structure together triggered abnormal brain function of children with ASD, which ultimately resulted in developmental motor disorders. In addition, the common neural basis shared by the developmental motor disorders and the core symptoms of ASD mainly included the mirror neuron dysfunction, the abnormalities of the thalamus, the basal ganglia, the cerebellum and mutations of SLC7A5 and PTEN. Future researches need to focus on other neurotransmitters closely related to motor, such as acetylcholine and dopamine, to explore the dynamic mechanism and formation of the neural network of developmental motor disorders, and to analyze the interaction between the underlying neural mechanisms of motor developmental disorders and that of core symptoms of autism.
