Abstract About every 26 months, the distance between Earth and Mars reaches a minimum, and that is the best time window for Mars exploration from Earth. In July 2020, three spacecraft started their journey to Mars: the Hope orbiter of the United Arab Emirates, the Tianwen-1 mission of China and the Perseverance rover of the United States’ National Aeronautics and Space Administration (NASA). If all go well, these spacecraft will reach Martian orbit in February 2021 and start their scientific observations. Tianwen-1 is China's first mission to Mars. It includes an orbiter, a lander and a rover. It carries 13 scientific payloads and will investigate the topography, soil composition, water-ice distribution, internal structure, atmospheric environment and physical fields (electromagnetic and gravitational) of Mars. In this interview, we talked with the mission's Chief Scientist Yongxin Pan (潘永信) and Scientific Payload Sub-System Director Chi Wang (王赤) about this scientific mission and China's future plans for Mars exploration.

This paper addresses some of the Muslim community’s concerns regarding its children’s education and reflects upon how education has shaped the position of other communities in American history. It argues that the future of Muslim education will be influenced directly by the present realities and future trends within American education in general, and, more importantly, by the well-calculated and informed short-term and long-term decisions and future plans taken by the Muslim community. The paper identifies some areas in which a wellestablished knowledge base is critical to making decisions, and calls for serious research to be undertaken to furnish this base.

There is a lack of comprehensive international studies on accommodations for people with disabilities; only small, local-level studies exist. This study aims to show the status of the tourist accommodation sector through the online distribution channel in terms of accessibility to offer more inclusive tourism. A descriptive analysis has been carried out with more than 31,000 hotels from the online travel agency Booking.com, in the 100 most touristic cities in the world. For the first time, an accurate picture of adaptation in the hotel sector for people with disabilities is presented. Results show that the adapted hotel infrastructures by countries are uneven. The main adaptations are those that help to avoid mobility barriers, and in contrast, hotels offer very few adaptations for sensory disabilities such as visual disabilities. Moreover, this study shows that, worldwide, countries with the highest income per capita, such as the United States of America, Canada, Ireland, Australia, New Zealand, Qatar or the United Arab Emirates, have the highest degree of hotel adaptation.

abstract The accuracy of stationary mathematical models of seismicity for calculating probabilities of damaging shaking is examined using the history of earthquakes in China from 1350 A.D. to 1949 A.D. During this time, rates of seismic activity varied periodically by a factor of 10. Probabilities of damaging shaking are calculated in 62 cities in North China using 50 yr of earthquake data to estimate seismicity parameters; the probabilities are compared to statistics of damaging shaking in the same cities for 50 yr following the data window. These comparisons indicate that the seismic hazard analysis is accurate if: (1) the maximum possible earthquake size in each seismogenic zone is determined from the entire seismic history rather than from a short-time window; and (2) the future seismic activity can be estimated accurately. The first condition emphasizes the importance of realistically estimating the maximum possible size of earthquakes on faults. The second indicates the need to understand possible trends in seismic activity where these exist, or to develop an earthquake prediction capability with which to estimate future activity. Without the capability of estimating future seismicity, stationary models provide less accurate but generally conservative indications of seismic ground-shaking hazard. In the United States, the available earthquake history is brief but gives no indication of changing rates of activity. The rate of seismic strain release in the Central and Eastern United States has been constant over the last 180 yr, and the geological record of earthquakes on the southern San Andreas Fault indicates no temporal trend for large shocks over the last 15 centuries. Both observations imply that seismic activity is either stationary or of such a long period that it may be treated as stationary for seismic hazard analyses in the United States.

Significance He did not name a new prime minister. Over July 25-26, Saied dismissed Prime Minister Hicham Mechichi, dissolved his government, suspended parliament for 30 days, lifted parliamentary immunity and declared himself chief prosecutor, triggering Tunisia’s worst political crisis in a decade. Impacts The Ennahda party could be persecuted once again, this time on corruption charges, as the reconciliation offered excludes its members. Tunisia may become a new ideological battleground, pitting Turkey and Qatar against the United Arab Emirates (UAE), Saudi Arabia and Egypt. The EU, the United States and Algeria have some influence on Tunisia and could perhaps play a moderating role.

The Impact

Background: Telestroke has led the technological revolution in providing acute medical services to rural areas in the United States since the beginning of this century. In January 2018 the American Stroke Association made a level IA recommendation to expand the treatment time window for endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) from 6 to 24 hours for anterior circulation stroke based on perfusion imaging. Our study is the first to our knowledge to report the effect of the expanded time window on acute stroke consult and treatment volumes in a large rural supporting telestroke network. Methods: Stroke registry data from two tertiary care facilities from a 22 hospital telestroke network supporting a large (> 78,000 mi 2 ) primarily rural Northwest geographic region were used. Data included stroke patients arriving within 24 hours of last known well (LKW) between January 2017 and March 2019. Patients arriving January 2017 to December 2017 were grouped into the PRE-expanded time window and those arriving April 2018 to March 2019 into the POST-expanded time window. Stroke subtypes, transfers, telestroke consults (via phone or video), and EVT treatments were compared across time periods. Analyses were performed using Pearson’s chi square test, corrected for multiple comparisons. Results: A total of 1117 patients arrived with stroke symptoms within 24 hours of LKW, 567 (50.8%) in PRE and 550 (49.2%) in POST-window. The percentage of all stroke subtypes were not significantly different in the PRE and POST patient groups (p=.720). However, the percent of telestroke consults increased by 12.1% from 62.3% to 74.4% (p<.001) but the percent of video consults remained similar (25.9% vs 25.8%). The total number of transfers (142 vs 141) and percentage of transfers among AIS patients (25.0% vs 25.6%) from partner to hub did not change. The percentage of thrombectomies among transfers rose by 8.7% with the expanded time window, but was not statistically significant [p=0.118]. Conclusions: In a large Northwest telestroke rural network the expanded EVT treatment time window led to a marked increase in all telestroke consults but did not impact video consults, transfer, or percentage of patients treated.

Abstract Background Educators agree on the importance of assessing the quality of graduate medical education. In the United States, the Accreditation Council for Graduate Medical Education (ACGME) resident survey is an important part of the accreditation process, yet some studies have questioned its validity. Objective We assessed the reliability and acceptance of the ACGME-International (ACGME-I) resident survey in the culturally distinct, nonnative English-speaking resident population of Abu Dhabi in the United Arab Emirates. Methods A total of 158 residents in ACGME-I accredited institutions in Abu Dhabi received an online link to the ACGME-I survey. Reliability analysis was conducted using the Cronbach α. A focus group was then held with a convenience sample of 25 residents from different institutions and specialties to understand potential challenges encountered by survey participants. Results Completed surveys were received from 116 residents (73.4%). The 39 items in the survey demonstrated high reliability, with a Cronbach α of 0.918. Of the 5 subscales, 4 demonstrated acceptable to very good reliability, ranging from 0.72 to 0.888. The subscale “resources” had lower reliability at 0.584. Removal of a single item increased the Cronbach α to a near-acceptable score of 0.670. Focus group results indicated that the survey met standards for readability, length, and time for completion. Conclusions The ACGME-I resident survey demonstrates acceptable reliability and validity for measuring the perceptions of residents in an international residency program. The data derived from the survey can offer an important set of metrics for educational quality improvement in the United Arab Emirates.

Trade Area

The European Union has met Donald Trump's presidency in a crisis, caused by Britain's exit, quarrels over migration policy and prospects for European integration. Trump has abandoned a project to create a transatlantic free trade area. He demanded a one-sided trade advantage for the United States. The rejection of the liberal project of multilateral foreign policy contributed to the deepening of contradictions between the EU and the US in the field of trade, environment, the regime of international disarmament treaties, the algorithm for resolving regional conflicts. The Trump era in US foreign policy was a time of abandoning liberal globalism. But it is impossible to realize this task in one cadence. The question is whether it is possible for Democrats to fully restore liberal globalism in equal cooperation with the European Union.Trump has abandoned the project of a transatlantic free trade area between the United States and the European Union. This shocked the European elites. Differences in approaches to world trade contributed to the coolness. The European Union is promoting a liberal approach. Trump insisted on the priority of the patronage of American interests. As a result, the tradition of relationships has suffered. Until 2017, the United States bought European goods and paid the most to the NATO budget. Trump demanded trade parity and more European funding for NATO. European elites perceived Trump's approach to migration issues as unacceptable. Trump's policy on international conflicts has become another reason for mutual misunderstanding. Trump recognized Jerusalem as the capital of Israel and helped establish diplomatic relations between Israel and the United Arab Emirates. This has become a challenge for the European Union's Middle East policy.

International students’ identities are complex and so are their needs. Semistructured interviews with 13 of the lead researcher’s former students from Dubai, United Arab Emirates, who are multi-national, multi-lingual and pursuing degrees in law, business, economics, medicine, education, art and media, in the United States, United Kingdom and Australia elucidated this reality. Their experiences demonstrated scholastic and pabulum frustrations that were offset in part by constant communication with their clans in person and through various technologies. Though the current model of higher education often seeks to identify and categorize international students as a group, this study shows that international students are unique individuals. Recognizing their individuality, higher education institutions and policymakers can more appropriately respond to international students’ needs.

The United States has the largest market share of international students at 22%, followed by the United Kingdom at 11% (Project Atlas, 2015). The U.S. share has decreased from 28% in 2001 although total numbers ofinternational students are increasing (Project Atlas, 2015). Decreased market share may be due to targeted national strategies in other countries to attract international students. These include immigration policies that not only expedite obtaining a student visa, but provide opportunities to work while studying and permanent jobs and residency after graduation (e.g., Canada, the Netherlands, Germany, Sweden) (Lane, 2015). Nations are also actively recruiting, providing databases with comprehensive information about studying in the country, (e.g., the Netherlands), and offering financial incentives (e.g., Germany)(Lane, 2015). In some cases, countries that once sent students to study abroad (United Arab Emirates, Singapore, Malaysia) are now actively recruiting to host students from their regions (Lane, 2015).
