Cardiovascular imaging analysis is a useful tool for the diagnosis, treatment and monitoring of cardiovascular diseases. Imaging techniques allow non-invasive quantitative assessment of cardiac function, providing morphological, functional and dynamic information. Recent technological advances in ultrasound have made it possible to improve the quality of patient treatment, thanks to the use of modern image processing and analysis techniques. However, the acquisition of these dynamic three-dimensional (3D) images leads to the production of large volumes of data to process, from which cardiac structures must be extracted and analyzed during the cardiac cycle. Extraction, three-dimensional visualization, and qualification tools are currently used within the clinical routine, but unfortunately require significant interaction with the physician. These elements justify the development of new efficient and robust algorithms for structure extraction and cardiac motion estimation from three-dimensional images. As a result, making available to clinicians new means to accurately assess cardiac anatomy and function from three-dimensional images represents a definite advance in the investigation of a complete description of the heart from a single examination. The aim of this article is to show what advances have been made in 3D cardiac imaging by ultrasound and additionally to observe which areas have been studied under this imaging modality.
High-quality implementation of cross-border mergers and acquisitions (cross-border M&As) is an important pathway for emerging-market multinational enterprises (EMNEs) to enhance their international competitiveness. However, in comparison to developed countries, cross-border M&As by EMNEs are often prohibited by the liability of origin caused by negative political coverage. How and why negative political coverage affect the completion of cross-border M&As by EMNEs? What are the contextual constraints that moderate the impact of negative political coverage on cross-border M&As completion? Based on the “liability of origin” theory, this paper addresses these questions using data from the Zephyr database on cross-border M&As by EMNEs in the United States from 2016 to June 2021 and employing a logit model for estimation. The research findings are as follows: (1) Negative political coverage leads to negative perceptions of emerging market countries by host country stakeholders, creating the liability of origin and stigmatizing the corporate nationality, thereby reducing the success rate of cross-border M&As by EMNEs. (2) Increasing geographical distance leads to information asymmetry, reinforcing the negative impact of negative political coverage on the completion of cross-border M&As by EMNEs. (3) Relevant mergers and acquisitions exacerbate the negative effect of negative political coverage on the success rate of cross-border M&As by EMNEs. (4) Being a publicly traded firm and having successful experience in cross-border M&As both intensify the negative impact of negative political coverage on the success rate of cross-border M&As by EMNEs.
This study offers a focused examination on Xinfang system, China’s unique mechanism particularly on its ability and efficacy in mediating land disputes between farmers and governmental bodies for social governance purposes. Based on interviews with 10 farmers, the study elucidates the system has low entry barriers and user-friendly, thus fast becoming the preferred system option when dealing with land conflicts. Xinfang facilitates direct communication between farmers and government officials, thereby in line with the sociocultural conventions of the rural populace. The study also highlights several constraints. While the Xinfang system employs a multifaceted approach to conflict resolution, including negotiation and grassroots governmental intervention, it lacks legislative power and institutional authority that are required for effective management of more complex or multi-stakeholder land disputes. The study advocates for a comprehensive reassessment and subsequent reform of the Xinfang system, focusing particularly on its mechanisms and procedures for dispute resolution. Such reforms are not merely instrumental for the more robust safeguarding of farmers’ land rights, but also for enhancing the overall integrity and public trust in China’s legal and administrative frameworks.
This paper aims to explore the issue of human actions in Islamic thought, focusing on the various stances regarding determinism, free will, and the intermediate position between them. This topic is linked to an ontological question: What are the limits of human responsibility for their actions? Our view is that the different positions on human actions reflect the presence of pluralism within Islamic thought, specifically through the discipline of Islamic theology (kalām). The difference in positions about the human actions within the science of theology expresses the vitality of Islamic thought and its appreciation of the right to differ between theological schools such as the Mu’tazila, Shi’a, and Sunnis, especially in an era dominated by the rationalism of Mu’tazila thought influenced by the methodology of Greek philosophical thought. This difference was recognized, especially in the third and fourth centuries AH/ninth and tenth centuries AD. We consider this difference in discussing the subject of the human actions as evidence of the principle of pluralism in Islam, which allows us to speak of the existence of a significant degree of intellectual tolerance, a subject that has not been studied to date. The prevailing view in studies today on this subject is that the theological groups accuse each other of unbelief, which is a mistaken position, because the saying of unbelief did not appear until after the fourth century AH/tenth century AD when transmission, reliability, and conservatism prevailed in Islamic thought. In addressing this issue, we examine three major stances on human actions as represented by three theological schools: The Mu’tazila (who advocated free will in human actions), the Jabriya (who advocated determinism in human actions), and the Ash’ariyya (who upheld the theory of acquisition). Once this is accomplished, we will explore the philosophy of pluralism in Islam through the lens of kalām. The most important conclusion we reached is that the debate on human actions opened, by the mid-4th century AH/10th century CE, an intellectual horizon that laid the foundations for pluralism in Islamic theological discussions. However, this horizon was soon closed due to various factors, which we have discussed throughout the paper.
As the involvement of Chinese enterprises in cross-border mergers and acquisitions (M&A) increases, on the one hand, it can drive enterprises to integrate with the international community and accelerate their transformation and upgrading, continuously enhancing their international competitiveness; on the other hand, it will also cause enterprises to experience more setbacks and challenges, especially the “weak acquisition of the strong” reverse cross-border acquisitions, which makes enterprises face a higher risk of failure. Reasonable control rights allocation can fully utilize the competitive advantages of enterprises, achieve synergistic cooperation among shareholders, board of directors, and management, promote the realization of enterprises’ cross-border acquisition goals, and thus enhance the value creation of acquisitions. There is a positive correlation between internal legitimacy and acquisition performance; the relevant assumptions about the distribution of shareholder control rights are invalid; the control rights at the board of directors level are negatively correlated with internal legitimacy and acquisition performance, and internal legitimacy has a mediating effect between the control rights at the board of directors level and acquisition performance, but the moderating effect of the acquisition mode is not significant; the control rights at the management level are negatively correlated with internal legitimacy and acquisition performance, and internal legitimacy has a mediating effect between the control rights at the management level and acquisition performance, and the acquisition mode negatively moderates the relationship between the control rights at the management level and internal legitimacy. This study takes the post-acquisition control rights allocation as the entry point, and examines the cross-border acquisition activities of Chinese enterprises from the perspective of stakeholders. The research results not only can enrich existing acquisition theory, but also can provide theoretical guidance for Chinese enterprise managers on allocation of control of target enterprises, and provide a theoretical basis for the state to formulate and optimize the system and policies of enterprises’ cross-border acquisitions.
The scientific objective of this study is to demonstrate how a hybrid photovoltaic-grid-generator microsystem responds under transient regime to varying loads and grid disconnection/reconnection. The object of the research was realized by acquiring the electrical magnitudes from the three PV systems (25 kW, 40 kW, and 60 kW) connected to the grid and the consumer (on-grid), during the technological process where the load fluctuated uncontrollably. Similar recordings were also made for the transient regime caused by the grid disconnection, diesel generator activation (450 kVA), its synchronization with PV systems, power supply to receivers, and grid voltage restoration after diesel generator shutdown. Analysis of the data focused on power supply continuity, voltage stability, and frequency variations. Findings indicated that on-grid photovoltaic systems had a 7.9% maximum voltage deviation from the standard value (230 V) and a frequency variation within ±1%. In the transient period caused by the grid disconnection and reconnection, a brief period with supply interruption was noted. This study contributes to the understanding of hybrid system behavior during transient regimes.
