International Meridian Circle Program

The Earth is buffered from the ferocious onslaught of the solar wind by a thin layer of matter known as the atmosphere and geospace.This layer absorbs energy from irradiance and outburst from the Sun,as well as from disasters,transient phenomena and anthropogenic emissions originated from Earth.Through complicated physics,the absorbed energy changes the atmospheric and geospace state and sometimes gets re-released to power extreme events such as space weather.Taking place globally,these complicated processes cannot be understood unless they are studied globally.The Chinese scientists have proposed the International Meridian Circle Program(IMCP)to meet this demand.By operating nearly 1000 instruments encompassing all latitudes along with the 120°E–60°W longitudes,IMCP aims,for the first time,to construct comprehensive 3D data representation of the atmosphere and geospace on a global scale and empower interdisciplinary research to tackle key questions related to Earth’s environment and climate change.

Progress of International Meridian Circle Program

Based on the Chinese Meridian Project(CMP),the International Meridian Circle Program(IMCP)aims to coordinate the deployment of a comprehensive ground-based monitoring network along the 120°E-60°W Great Meridian Circle to track the propagation and evolution of space weather events from the Sun to the Earth,as well as the imprints of other major natural and anthropic hazards on the ionosphere,the middle and upper atmosphere.Currently,we have completed the IMCP headquarters building in Beijing and established the China-Brazil Joint Laboratory for Space Weather in cooperation with Brazil.Meanwhile,the Chinese Meridian Project PhaseⅡand different components of the IMCP observation system are under construction.

Strangers in a New Land: Rural School Personnel’s Perceptions of the Implementation of an International Student Program

Many high schools in the northeastern United States have suffered from declining enrollment due to a declining population of school-age children in the region.Administrators,counselors and teachers perceive many impacts of the implementation of an international student program at a rural high school.This qualitative case study reveals that the rural high school’s unique nature impacts international student programs,international students influence both school culture and programming,and international students suffer from isolation.School leaders would benefit from considerations in the form of professional development both prior to implementation of an international student program and ongoing throughout its duration.It is important for schools to find ways to respectfully honor student cultures and optimize learning experiences.School leaders would be wise to determine desired size of international student programs and make efforts accordingly to achieve that size for optimal effectiveness for the benefit of both host and international students.Implications and recommendations for future research include further exploration of the perceived experiences of European and Chinese international students,understanding the unique nature of rural high schools and international student experiences,and examination of school practices.

Progress of International Meridian Circle Program

In 2024,the Chinese Meridian Project(CMP)completed its construction,deploying 282 instruments across 31 stations.This achievement not only provides a robust foundation but also serves as a reference template for the International Meridian Circle Program(IMCP).The IMCP aims to integrate and establish a comprehensive network of ground-based monitoring stations designed to track the propagation of space weather events from the Sun to Earth.Additionally,it monitors various disturbances generated within the Earth system that impact geospace.Over the past two years,significant progress has been made on the IMCP.In particular,the second phase of construction for the China-Brazil Joint Laboratory for Space Weather has been completed,and the North Pole and Southeast Asia networks are under active construction.The 2024 IMCP joint observation campaign was successfully conducted.To facilitate these developments,the scientific program committee of IMCP was established,following the success of 2023 IMCP workshop and the space weather school,which was co-hosted with the Asia-Pacific Space Cooperation Organization(APSCO)and sponsored by Chinese Academy of Sciences(CAS)and Scientific Committee on Solar-Terrestrial Physics(SCOSTEP).Preparations are now underway for the 2024 workshop in collaboration with the National Institute for Space Research(INPE)in Brazil.

Sciatic nerve repair using adhesive bonding and a modified conduit

When repairing nerves with adhesives, most researchers place glue directly on the nerve stumps, but this method does not fix the nerve ends well and allows glue to easily invade the nerve ends. In this study, we established a rat model of completely transected sciatic nerve injury and re- paired it using a modified 1 cm-length conduit with inner diameter of 1.5 mm. Each end of the cylindrical conduit contains a short linear channel, while the enclosed central tube protects the nerve ends well Nerves were repaired with 2-octyl-cyanoacrylate and suture, which complement the function of the modified conduit. The results demonstrated that for the same conduit, the av- erage operation time using the adhesive method was much shorter than with the suture method. No significant differences were found between the two groups in sciatic function index, motor evoked potential latency, motor evoked potential amplitude, muscular recovery rate, number of medullated nerve fibers, axon diameter, or medullary sheath thickness. Thus, the adhesive method for repairing nerves using a modified conduit is feasible and effective, and reduces the operation time while providing an equivalent repair effect.

Scientific challenges and instrumentation for the International Meridian Circle Program

Earth’s ecosystems and human activities are threatened by a broad spectrum of hazards of major importance for the safety of ground infrastructures,space systems and space flight:solar activity,earthquakes,atmospheric and climatic disturbances,changes in the geomagnetic field,fluctuations of the global electric circuit.Monitoring and understanding these major hazards to better predict and mitigate their effects is one of the greatest scientific and operational challenges of the 21st century.Though diverse,these hazards share one feature in common:they all leave their characteristic imprints on a critical layer of the Earth’s environment:its ionosphere,middle and upper atmosphere(IMUA).The objective of the International Meridian Circle Program(IMCP),a major international program led by the Chines Academy of Sciences(CAS),is to deploy,integrate and operate a global network of research and monitoring instruments to use the IMUA as a screen on which to detect these imprints.In this article,we first show that the geometry required for the IMCP global observation system leads to a deployment of instruments in priority along the 120°E-60°W great meridian circle,which will cover in an optimal way both the dominant geographic and geomagnetic latitude variations,possibly complemented by a second Great Circle along the 30°E-150°W meridians to capture longitude variations.Then,starting from the Chinese Meridian Project(CMP)network and using it as a template,we give a preliminary and promising description of the instruments to be integrated and deployed along the 120°E-60°W great circle running across China,Australia and the Americas.

What They Learned Won't Go Away:The Impacts ofan International Exchange Program on Chinese Teacher Candidates' Understanding of and Practice in Science Education

Purpose:The Canadian university where this study took place has established an international exchange program in teacher education with a large Chinese university.This study was designed to examine how the international exchange program influenced Chinese science teacher candidates'understanding of science education and how such learning impacted their teaching in China.Design/Approach/Methods:The study adopted a qualitative research design with interview and reflective journal as the main approaches for data collection.Findings:Participants greatly appreciated the opportunity of exchange.They reported an improved understanding of Canadian school education and its science curriculum and pedagogy,which changed many aspects of their original values about the relationship between the teacher and students,classroom environment,and so on.Although they faced many constraints to implement what they learned from the exchange in Chinese science classrooms,what they learned had never been forgotten.Participants tried to apply them here and there at the level they could control.Originality/Value:There are many reported studies in the literature about Chinese international students on Western campuses.However,research on Chinese students who participate in international exchange programs is very rare.The findings of this study can inform policymakers and education practitioners about student international exchange programs and benefit future exchange participants.

Prof.Ackermann,vision-based navigation and the PG master’s degree programme at HfT Stuttgart

The two topics of the article seem to have absolutely nothing to do with each other and,as can be expected in a contribution in honor and memory of Prof.Fritz Ackermann,they are linked in his person.Vision-based Navigation was the focus of the doctoral thesis written by the author,the 29th and last PhD thesis supervised by Prof.Ackermann.The International Master’s Program Photogrammetry and Geoinformatics,which the author established with colleagues at Stuttgart University of Applied Sciences(HfT Stuttgart)in 1999,was a consequence of Prof.Ackermann’s benevolent promotion of international knowledge transfer in teaching.Both topics are reflected in this article;they provide further splashes of color in Prof.Ackermann’s oeuvre.

Cardiovascular risk and prevalence of metabolic syndrome by differing criteria

Background The prevalence of metabolic syndrome （MetS） in hypertensive population in Chinese countryside is unknown. Firstly, this study compared the prevalence of MetS according to National Cholesterol Education Program （NCEP） ATPIII, revised NCEP and International Diabetes Federation （IDF） definitions. Secondly, it investigated the association between MetS, coronary heart disease （CHD） and stroke in patients with hypertension. Methods In this cross sectional study, the cluster sampling method was used. Three MetS definitions were applied to 1418 normal subjects and 5348 hypertensive patients aged 40-75 years in rural areas in China. The agreement between different MetS definitions was estimated by K statistics. Logistic regression analyses determined the association between MetS defined by the three MetS definitions and CHD and stroke. Results In subjects without hypertension, the prevalence of Mets was 4.1% by NCEP definition, 8.3% revised NCEP definition and 7.8% IDF definition. In hypertensive individuals, the prevalence was 14.0%, 32.9%, and 27.4% in men; 35.6%, 53.1%, and 50.2% in women by the same definitions, respectively. In hypertensive individuals, the agreement was 94.4% in men and 97.0% in women between revised NCEP and IDF definitions. The IDF defined MetS was more strongly associated with CHD than the NCEP or revised NCEP defined MetS （adjusted odds ratio： 1.92 compared with 1.85 and 1.69 in men; 1.64 compared with 1.48 and 1.60 in women）. Conclusions In the patients with hypertension, the revised NCEP and IDF definitions identified more individuals than NCEP definition and their agreement is very high. The IDF defined MetS is more strongly associated with CHD than the NCEP or revised NCEP defined MetS, but weakly or not associated with stroke.
