PurposeThis paper aims to analyze the exchange and reciprocal mechanism behind individual knowledge transfer activities as well as their impact on the individual knowledge transfer networks.Design/methodology/approachThe author conducted theoretical and simulation research. Agent‐based technology is employed to construct an agent dynamics agent‐based model that simulates and explains how an individual initiates the evolution of a knowledge network through knowledge transfer activities.FindingsThe results demonstrate that the two mechanisms can improve the knowledge levels of the network members; the exchange mechanism is more efficient as it can improve the values of both sides. Individual knowledge transfer networks evolve from random networks to small‐world networks.Research limitations/implicationsThe research model must include more variables. Computer simulation research will be cross‐confirmed by other research methods in future studies.Practical implicationsIndividual knowledge transfer networks form and subsequently evolve as a result of social interaction. The research findings will contribute to the policy making for knowledge management in organizations.Originality/valueLittle has been published about the dynamics of individual knowledge transfer networks. The author believes that the paper is the first to analyze the internal mechanisms behind individual knowledge transfer activities and test them with agent‐based technologies.

We report the prenatal diagnosis of 6 cases of Prune-belly syndrome in the 2(nd) trimester. The sonographic diagnosis was based on the findings of oligohydramnios, renal anomalies, and a lower abdominal cystic mass representing the abnormal dilatation of the bladder on conventional 2-dimensional sonographic examination. We discuss the role of Doppler imaging and 3-dimensional sonography as complementary methods to conventional sonography. Four of our 6 cases were confirmed with associated defects.

The study on the hydraulic properties of coastal aquifers has significant implications both in hydrological sciences and environmental engineering. Although many analytical solutions are available, most of them are based on the same basic assumption that assumes aquifers extend landward semi‐infinitely, which does not necessarily reflect the reality. In this study, the general solutions for a leaky confined coastal aquifer have been developed that consider both finitely landward constant‐head and no‐flow boundaries. The newly developed solutions were then used to examine theoretically the joint effects of leakage and aquifer length on hydraulic head fluctuations within the leaky confined aquifer, and the validity of using the simplified solution, which assumes the aquifer is semi‐infinite. The results illustrated that the use of the simplified solution may cause significant errors, depending on joint effects of leakage and aquifer length. A dimensionless characteristic parameter was then proposed as an index for judging the applicability of the simplified solution. In addition, practical application of the general solution for the constant‐head inland boundary was used to characterize the hydraulic properties of a leaky confined aquifer using the data collected from a field site at the Seine River estuary, France, and the versatility of the general solution was further justified.

In this paper, we present an efficient Computer Generated Integral Imaging (CGII) method, called multiple ray cluster rendering (MRCR). Based on the MRCR, an interactive integral imaging system is realized, which provides accurate 3D image satisfying the changeable observers' positions in real time. The MRCR method can generate all the elemental image pixels within only one rendering pass by ray reorganization of multiple ray clusters and 3D content duplication. It is compatible with various graphic contents including mesh, point cloud, and medical data. Moreover, multi-sampling method is embedded in MRCR method for acquiring anti-aliased 3D image result. To our best knowledge, the MRCR method outperforms the existing CGII methods in both the speed performance and the display quality. Experimental results show that the proposed CGII method can achieve real-time computational speed for large-scale 3D data with about 50,000 points.

The fetal plantar shape can provide valuable information for prenatal diagnosis of clubfoot. Compared with a normal foot, a clubfoot tends to be wider and shorter. A higher width to length ratio is associated with a smaller bimalleolar angle and indicates a more severe talipes equinovarus deformity.

We propose the combined use of CM level location and CS distance measurement for the prenatal diagnosis of fetal spinal lesions for complementary needs.

Under the condition of elastic demand and different market scales, the optimization of multiproduct supply chain by the Internet of Things (IoT) technology was studied from the perspective of overall supply chain revenue in this paper. Particularly, the supply chain revenue model in a two-stage multi-product supply chain is established to analyze the impact of the IoT technology on the overall supply chain revenue. The imperialist competitive algorithm is introduced, and the algorithm is improved to solve the model. The computer simulation optimization method is used to solve the example and to compare the overall supply chain revenue and its changes before and after introducing the IoT technology. The result shows that the application of the IoT technology can effectively optimize the multi-product supply chain.INDEX TERMS Multi-product supply chain, Internet of Things (IoT) technology, supply chain optimization, imperialist competitive algorithm (ICA), revenue model.

Based on the background of Chinese oil politics under Xi Jinping, this article studies the “structural power of business” to test the concept within the economic system of state capitalism. Many elements of structural power discourse are valid, such as the political influence of business, the role of information‐expertise, the role of business competitiveness and fluidity, and the effect of external factors. However, the dominance and mechanism of the structural power of Chinese national oil companies presents differently because of the unique state‐business relations in the Chinese oil sector.
