Governments around the world have introduced a number of stringent policies to try to contain COVID-19 outbreaks, but the relative importance of such measures, in comparison to the community response to these restrictions, the amount of testing conducted, and the interconnections between them, is not well understood yet. In this study, data were collected from numerous online sources, pre-processed and analysed, and a number of Bayesian Network models were developed, in an attempt to unpack such complexity. Results show that early, high-volume testing was the most crucial factor in successfully monitoring and controlling the outbreaks; when testing was low, early government and community responses were found to be both critical in predicting how rapidly cases and deaths grew in the first weeks of the outbreak. Results also highlight that in countries with low early test numbers, the undiagnosed cases could have been up to five times higher than the officially diagnosed cases. The conducted analysis and developed models can be refined in the future with more data and variables, to understand/model potential second waves of contagions.

The past sixteen years have witnessed the proliferation of international commercial courts around the world. However, up until recently, this was largely an Asian and a Middle Eastern phenomenon. Only during the past decade have Continental European countries, notably Germany, France and the Netherlands, joined the bandwagon and started to create new judicial bodies for international commercial cases. Driven by the desire to attract high-volume commercial litigation, these bodies try to offer international businesses a better dispute settlement framework. But what are their chances of success? Will more international litigants decide to settle their disputes in these countries? In this essay, I argue that, despite its recently displayed activism, Continental Europe lags behind on international commercial courts. In fact, although the various European initiatives are laudable, most cannot compete with the traditional market leaders, especially the London Commercial Court, or with new rivals in Asia and the Middle East. If Continental Europe wants a role in the international litigation market, it must embrace more radical change. And this change will most likely have to happen on the European––not the national––level.

AbstractCOVID-19 has crippled the world’s healthcare systems, setting back the economy and taking the lives of several people. Although potential vaccines are being tested and supplied around the world, it will take a long time to reach every human being, more so with new variants of the virus emerging, enforcing a lockdown-like situation on parts of the world. Thus, there is a dire need for early and accurate detection of COVID-19 to prevent the spread of the disease, even more. The current gold-standard RT-PCR test is only 71% sensitive and is a laborious test to perform, leading to the incapability of conducting the population-wide screening. To this end, in this paper, we propose an automated COVID-19 detection system that uses CT-scan images of the lungs for classifying the same into COVID and Non-COVID cases. The proposed method applies an ensemble strategy that generates fuzzy ranks of the base classification models using the Gompertz function and fuses the decision scores of the base models adaptively to make the final predictions on the test cases. Three transfer learning-based convolutional neural network models are used, namely VGG-11, Wide ResNet-50-2, and Inception v3, to generate the decision scores to be fused by the proposed ensemble model. The framework has been evaluated on two publicly available chest CT scan datasets achieving state-of-the-art performance, justifying the reliability of the model.

Abstract Industry 4.0 is a great opportunity and a tremendous challenge for every role of society. Our study combines complex network and qualitative methods to analyze the Industry 4.0 macroeconomic issues and global supply chain, which enriches the qualitative analysis and machine learning in macroscopic and strategic research. Unsupervised complex graph network models are used to explore how industry 4.0 reshapes the world. Based on the in-degree and out-degree of the weighted and unweighted edges of each node, combined with the grouping results based on unsupervised learning, our study shows that the cooperation groups of Industry 4.0 are different from the previous traditional alliances. Macroeconomics issues also are studied. Finally, strong cohesive groups and recommendations for businessmen and policymakers are proposed.

Introduction: The COVID-19 pandemic has strained the healthcare systems across the world but its impact on acute stroke care is just being elucidated. We hypothesized a major global impact of COVID-19 not only on stroke volumes but also on thrombectomy practice. Methods: A 19-item questionnaire survey aimed to identify the changes in stroke volumes and treatment practices seen during COVID-19 pandemic was designed using Qualtrics software. It was sent to stroke and neuro-interventional physicians around the world who are part of the executive committee of a global coalition, Mission Thrombectomy 2020 (MT2020) between April 5 th to May 15 th , 2020. Results: There were 113 responses across 25 countries. Globally there was a median 33% decrease in stroke admissions and a 25% decrease in mechanical thrombectomy (MT) procedures during COVID-19 pandemic compared to immediately preceding months (Figure 1A-B). This overall median decrease was despite a median increase in stroke volume in 4 European countries which diverted all stroke patients to only a few selected centers during the pandemic. The intubation policy during the pandemic for patients undergoing MT was highly variable across participating centers: 44% preferred intubating all patients, including 25% centers that changed their policy to preferred-intubation (PI) vs 27% centers that switched to preferred-conscious-sedation (PCS). There was no significant difference in rate of COVID-19 infection between PI vs PCS (p=0.6) or if intubation policy was changed in either direction (p=1). Low-volume (<10 stroke/month) compared with high-volume stroke centers (>20 strokes/month) are less likely to have neurointerventional suite specific written personal protective equipment protocols (74% vs 88%) and if present, these centers are more likely to report them to be inadequate (58% vs 92%). Conclusion: Our data provides a comprehensive snapshot of the impact on acute stroke care observed worldwide during the pandemic.

The use of electronic money as a transaction tool in everyday life is a necessity, people use the money to pay for various needs such as buying goods in the marketplace, buying food online, KRL train tickets, paying toll tickets and others. On the other hand, the use of electronic money in society raises questions, especially for Muslims. Is electronic money as a medium of exchange in accordance with the Qur'an and As-Sunnah? Several Indonesian Muslim scholars who are concerned about the practice of Muamalah Maaliyah have given their thoughts and opinions on the use of electronic money. This paper is a step in answering this question. This paper will try to provide an explanation why the use of electronic money is not in accordance with the Qur'an and As-Sunnah. This research uses case study – qualitative research as research methodology. For this study, data were collected from documentation: Bank Indonesia regulations, the fatwa of the Sharia Council-Indonesian Ulema Council (DSN-MUI), fatwas of world scholars, instructions for the use of electronic money from banks/issuing companies, participant observations and observations, namely as users of electronic money who also use electronic money. Experienced as a banker in a state-owned bank. Using this method, this research will explore and explain how electronic money is managed and why some Muslims doubt this money. The conclusion of this study is that Bank Indonesia as the regulator and DSN-MUI issued a fatwa and this is in line with the fatwa issued by Majma' al-Fiqh al-Islami under the World Muslim League in its decision No. 86, 3/9 explains that “bank deposits, both in Islamic banks and conventional banks, from the fiqh point of view are debt, having different views on the concept and characteristics of electronic money used in Indonesia. The solution to this problem is that Bank Indonesia as a regulator needs to open space so that electronic money that is in accordance with sharia provisions can be realized so that the interests of the Muslim community are met. Abstrak Penggunaan uang elektronik sebagai alat transaksi dalam kehidupan sehari-hari adalah suatu keniscayaan, masyarakat menggunakan uang tersebut untuk membayar berbagai keperluan seperti membeli barang di marketplace, membeli makanan secara online, tiket kereta api KRL, membayar tiket tol dan lain-lain. Di sisi lain, penggunaan uang elektronik di masyarakat menimbulkan pertanyaan terutama bagi umat Islam. Apakah uang elektronik sebagai alat tukar sesuai dengan Al-Qur'an dan As-Sunnah? Beberapa cendekiawan muslim Indonesia yang concern terhadap praktik Muamalah Maaliyah telah memberikan pemikiran dan pendapatnya tentang penggunaan uang elektronik. Tulisan ini merupakan langkah dalam menjawab pertanyaan tersebut. Tulisan ini akan mencoba memberikan penjelasan mengapa penggunaan uang elektronik tidak sesuai dengan Al-Qur’an dan As-Sunnah. Penelitian ini menggunakan studi kasus – penelitian kualitatif sebagai metodologi penelitian. Untuk penelitian ini data dikumpulkan dari dokumentasi: ketentuan Bank Indonesia, fatwa Dewan Syariah-Majelis Ulama Indonesia (DSN-MUI), fatwa ulama sedunia, instruksi penggunaan uang elektronik dari bank/perusahaan penerbit, observasi dan observasi partisipan yaitu sebagai pengguna uang elektronik yang juga berpengalamanan sebagai bankir di bank milik pemerintah. Dengan menggunakan metode ini, penelitian ini akan mengeksplorasi dan menjelaskan bagaimana uang elektronik dikelola dan mengapa sebagian umat Islam meragukan uang ini. Kesimpulan dari penelitian ini adalah Bank Indonesia selaku regulator dan DSN-MUI yang mengeluarkan fatwa dan ini sejalan dengan fatwa yang dikeluarkan oleh Majma’ al-Fiqh al-Islami di bawah Liga Muslim Dunia dalam keputusannya No. 86, 3/9 menerangkan bahwa “simpanan bank, baik di bank Islam maupun bank konvensional, dari sudut pandang fiqih merupakan hutang, memiliki pandangan yang berbeda mengenai konsep dan karakteristik uang elektronik yang digunakan di Indonesia. Solusi dari permasalahan ini adalah Bank Indonesia sebagai regulator perlu membuka ruang agar uang elektronik yang sesuai dengan ketentuan syariah dapat diwujudkan sehingga kepentingan masyarakat muslimin terpenuhi.
