Spatiotemporal Pattern Evolution in Global Green Trade Networks: Implications for Health Economics

Big health industry is an industry that provides whole process and all factor products and services for human comprehensive physical and mental health.With the increasingly close relationship between health and environment, green products take into account the characteristics of environmental protection, resource intensification, safety, and health, so that the green product industry for the purpose of health and environmental protection has become an important branch of the big health industry.To give a clear portrayal of changes in the global green product trade system, this study derives relevant trade data from the world bank and the un comtrade and by analyzing the spatiotemporal evolution characteristics of the global green product trade pattern from 2001 to 2018, and it explores the product structure and status changes of countries (regions) in the global trading system for green products.According to the research findings, the closely connected global trade network for green products continues to expand.This is a typical network comprising “smaller worlds”; the focus of green product exports has largely stayed unchanged, while imports are shifting from north america and east asia towards north america, europe, and the middle east; the spatial structure of the network shows a transition away from the original transcontinental “dual arch” pattern with the united states at the core towards a “transcontinental + intracontinental” one characterized by the coexistence of “multiple arches” centering around europe and asia; the trade network adopts a “point-to-point” model, with no obvious interdependence and competition between countries (regions); furthermore, geographically proximate and culturally similar countries are prone to have closer trade ties.By clarifying the global trade network of green products industry under the background of big health industry, it will help to deepen the understanding of the relationship between participating countries, promote the long-term and stable development of national health industry trade, provide the public with more safe and harmless products, better meet the global public’s health needs, and effectively enhance the sustainability of public health.

Simulation Study on the Spatiotemporal Difference of Complex Neurodynamics between P3a and P3b

The integration of event-related potential (erp) and functional magnetic resonance imaging (f mri) helps to obtain and study neural networks with high temporal and spatial resolution.Eeg/f mri data proves that in the visual tristimulus oddball paradigm, two p300 potentials (p3a and p3b) induced by target stimulation and novel stimulation are detected at the frontal-middle (fz), center (cz), and mid-apical (pz) electrodes.Previous studies have shown that p3a and p3b have different spatial distributions of brain activation, but it is unclear whether they have the same neural mechanism.The purpose of this study is to determine the neuropsychological mechanisms of p3a and p3b, as well as the spatiotemporal differences in neurodynamics between the two erp subcomponents.In a group of 25 subjects, p300 erp induced by target stimulation and novel stimulation can be detected at the fz, cz, and pz electrodes.At cz and fz, compared with p3b related to the target stimulus, the p3a related to the novel stimulus has a higher amplitude and the waveform declines more slowly.But at pz, p3b has a higher amplitude than p3a.P3a appeared earlier than p3b at cz and fz, but the opposite phenomenon was observed at the pz electrode.The activated brain regions of p3a included the left frontal-parietal lobe region, left anterior wedge lobe region, and right insula, while the target-driven p3b was significantly associated with bold changes in the bilateral fusiform gyrus, the left frontal region, and the bilateral insula.The results showed that the integration of the spatial and temporal information of the two imaging modes, namely, erp and f mri, proves the existence of the different brain function processes of the two p300 subcomponents.Through the analysis of the composition of p300, the results further proved that the top-down and bottom-up processing processes have played a role in the occurrence of attention capture.It is just that the modulation effects of the two processing mechanisms are different in different tasks.Therefore, it should be noted that the captured neural mechanism is not a single top-down or bottom-up processing process but should be the result of the interaction between the two.

Research on Mapping Error Control of Underground Space Mobile LiDAR Constrained by Cooperative Targets

In the underground environment, it is difficult to obtain spatial three-dimensional data because of occlusion and its complexity.Mobile light detection and ranging (li dar) measurement technology has the ability to obtain three-dimensional spatial information quickly and accurately, but in the underground environment, because of the lack of global navigation satellite system (gnss) signal in the integrated navigation system, the measurement accuracy decreases with the increase of time.In this paper, an extended kalman filter-based loose mode is constructed using the real coordinates of the center of gravity of the target and the measurement information of the laser foothold.It provides an additional space-time reference for the integrated navigation system of the mobile li dar system and restricts the errors.The simulation results show that the proposed method can effectively improve the measurement accuracy of mobile li dar system and enhance the 3d spatial perception ability of underground space.

Real-Time Animation Complexity of Interactive Clothing Design Based on Computer Simulation

With the innovation of computer, virtual clothing has also emerged.This research mainly discusses the real‐time animation complex of interactive clothing design based on computer simulation.In the process of realizing virtual clothing, the sample interpolation synthesis method is used, and the human body sample library is constructed using the above two methods (primitive construction method and model reconstruction method) first, and then, the human body model is obtained by interpolation calculation according to the personalized parameters.Building a clothing model is particularly important for the effect of trying on.The clothing that needs to be displayed can be scanned and then input into the computer to build the model.The model can be directly built in 3dmax and other software and then its surface texture can be mapped, or the clothing model can be directly built.The 3d model in the 3ds file is loaded by the loop body nested switch branch selection structure.Correspondingly, the write‐back operation of 3ds files is similar.Just follow the general structure of the 3ds file and write the root block, version information block, edit information block, key frame information block, etc.To a brand new file in sequence.The main reason for this article to perform the 3ds file write‐back operation is that, after the clothing model is dynamically simulated through the dynamic principle, the deformed key animation frame needs to be saved as a 3ds file so that it can be further imported into the 3dsmax software and generated by the renderer, form high‐quality picture information, and finally get high‐definition animation video.In the cpu‐gpu hybrid method, modules such as force calculation, collision processing, and position update use the gpu method, while overstretching is processed by the cpu method, making the overall performance 10 times higher than the pure cpu method.This research helps to promote the development of 3d virtual clothing design.
