February 26 marks the first day of UCASers’ spring semester in 2024. After a brief break for the Spring Festival, ICTP-APers have gone back to school for a new semester. During the winter vocation, teachers and students have captured the beautiful scenery with their lenses and now let's take a look at their spectacular shootings. From this photo, we can see that the tree is decorated with many red lanterns because it is a custom for Chinese to adorn their doors with red couplets and colorful lantersn to enrich the festival asmosphere. This group of photo displays the beautiful scenery after snow.These two photos were taken in Macau and HK respectively, the first one is the fireworks set to celebrate the Chinese New Year and the second one is the Ferris Wheel featured by four Chinese characters “Long Lai Yun Zhuan”, which means that luck comes to you as the Year of the Dragon approaches.This photo is taken at the front gate of the Old Summer Palace, which is also known as “Yuanmingyuan”This photo is taken in Guangzhou.The Spring Festival is one of the most significant traditional celebrations in Chinese culture, marking a momentous occasion for family gatherings and shared joy. The year of 2024 is also the Year of the Dragon or Loong, therefore, the dragon rightfully takes center stage. Now, let us warmly welcome the auspicious dragon and together create a symphony of happiness for the new year.Home is where the heart is. In the 2024 Spring Festival, ICTP-APers scattered across the country, yet their hearts and hands are still connected. This traditional holiday of bidding farewell to the old and welcoming the new has become a collective journey that fosters a sense of belonging, fulfillment, and happiness among the ICTP-AP community. Amidst the warmth and nostalgia, it adds new meaning and responsibility to the Dragon Year's new spring, making everyone’s heart warmer, bringing students and faculty closer, and strengthening their love for UCAS.

The 2023 Winter School on Frontier and Interdisciplinary Sciences was held from 14th January to 20th January in Yunnan Province. It was organized by the International College and the International Centre for Theoretical Physics-Asia-Pacific, and hosted by Kunming Institute of Zoology, Kunming Institute of Botany and Xishuangbanna Tropical Botanical Garden of CAS. Over 60 students from different institutes of CAS participated in the 6-day activity. A Journey of Interdisciplinary SciencesDuring the winter school, we have invited experts and professors from different fields, including botany, zoology, ecology, microbiology, environmental science, biochemistry and molecular biology, medicinal chemistry, pharmacology, bioinformatics, cell biology and genetics, so as to encourage students to engage in interdisciplinary scientific research and innovative exploration across different disciplines.We have also invited a professor from the Foreign Language School of Yunnan University to deliver a report on China’s national condition, enabling a valuable opportunity for international students to have a glimpse of the history, culture, music and development of China. A Journey of LifeAs one of a few areas that have tropical forests at about 20 degrees North latitude, Yunnan province is well-known for its plant diversity. Thanks to its various geographic features, Yunnan is also rich in animal resources. During this winter school, we have also arranged a field study in Fu Li Palace Greenhouses and Tea Garden at Kunming Institute of Botany, the Kunming Natural History Museum of Zoology and Xishuangbanna Tropical Forest Garden. Students were impressed by the biodiversity of Yunnan and learned a lot about the animal and plant species in those gardens and museums, inspiring them to carry out cross-disciplinary scientific research and value the importance of biodiversity to sustainable development. A Journey of CultureDuring the 6-day school, we have also brought the international students to the memorial hall of the National Southwest Associated University (SWAU). Built in Kunming during the War of Resistance against Japanese Aggression, SWAU represented a merger of Peking University, Tsinghua University, and Nankai University as a comprehensive university. Over its eight-year tenure, the university was a gathering place of accomplished masters and renowned scholars, including Chen-Ning Yang and Tsung-Dao Lee.Walking on the quiet campus, students and teachers travelled back to the time when the students had to read in the tea house and worked hard to strive for the country’s development. Another meaningful trip took place in a socialist new village--Chengzi Village in Menglun County, Xishuangbanna. Guided by a local villager, we went into the small village, which has about 300 households. The buildings are all traditional Dai-style. Yet, instead of rammed earth and thatch, the buildings are all made of cement and bricks, which are more solid and water-proof.International students were surprised by China’s rural development and one student from Tajikistan noticed that many households have stuck the photos of President Xi on the walls and asked why. “That is because the houses used to be decrepit and Chinese government started to help them restore their houses and explore local tourism resources and bring in innovative ways to increase the income of local residents since 2012”, answered Ms Zhang, from ICTP-AP. Then she pointed at the QR-code hung up on the fruit trees grown on the side of the path and explained that visitors can pick the fruit from the tree and pay by scanning the QR-code without talking to the owner. When we came to a local household, we were invited to make local snacks with the Dai people. Students enjoyed themselves and deeply experienced China’s cultural diversity and ethnic harmony and unity. After the six-day learning and experiencing, the international students have broadened their horizons and strengthened their friendship with students from different institutes. They have also learnt more about China’s national condition and cultural diversity.

Einstein predicted the existence of gravitational waves in 1916, and the LIGO（Laser Interferometer Gravitational Wave Observatory）Collaboration announced the first direct detection of gravitational waves in human history on 11th February,2016 after a century’s exploration, which opens a new window to explore the universe. The detection of gravitational wave signals in the low and mid-frequency bands is needed in order to hear the motions of more massive objects. There are a lots of new gravitational waves sources in this band, which require the construction of space-based gravitational wave observatories. Taiji Program proposed by Chinese scientists is one of the space-based GW detection plans, which is proposed to launch three spacecrafts which will form an equilateral triangle in orbit around the Sun, with 3million kilometers length of each side, composing three sets of Michelson Interferometers.Taiji ProgramTaiji-1, as the technology verification satellite of the Taiji Program, was successfully launched on August 31, 2019, and has completed verification on key technologies, taking the first step towards China’s space-borne gravitational waves detection. The Gravity Reference Sensor (GRS), a main payload of the Taiji-1 satellite, is the endpoint and reference of the laser link of the future space-based gravitational wave detection satellite, to ensure that the test mass moves perfectly along the geodesic line, which is a prerequisite for the detection of gravitational wave signals. The inertial reference of the GRS is determined by the residual acceleration noise of its test mass, which means that the ambient noise need to be suppressed or subtracted.The calibration of the GW detection device’s core payload is a critical step in achieving the space-based GW detection. Recently, the research of calibration of the in-orbit center-of-mass of TaiJi-1 was published in Physical Review D [Phys. Rev. D 108 (2023) 082001]. Xiaotong Wei, a Ph.D. student of the class of 2020 at the International Center for Theoretical Physics-Asia-Pacific (ICTP-AP), is the first author and co-corresponding author of this paper, and his advisor, Prof. Jibo He, is the co-corresponding author as well. After calibration, the acceleration noise level of the gravitational reference sensor readout data in the medium-and-low-frequency band (0.001 to 0.1 Hz) was significantly reduced. The study was favorably reviewed by the referees of Physical Review D:“…Calibration of space-borne instruments is an important foundation for science…In general, the paper and the results are really good…”.This research was supported by the colleagues from the partner institutions of Taiji Alliance and the Strategic Priority Research Program of the Chinese Academy of Sciences (CAS)(XDA15020700, XDA15021100), as well as the Special Funds of the Fundamental Research Funds for Central Universities from the Ministry of Education of the People's Republic of China.Download the paper: https://doi.org/10.1103/PhysRevD.108.082001Center-of-mass calibration before (red dashed line) and after (blue) GRS triaxial readout of acceleration amplitude spectrum density

To celebrate the Mid-Autumn Festival, ICTP-AP has held a gathering party at Zhongguancun Campus, over thirty students signed up for the event and actively took part in this activity. ICTP-AP has prepared many delicate gifts for the participants, including small pouch filled with sweet Osmanthus flowers. To warm up the atmosphere, we also prepared a dozen of English and Chines riddles for the guests to solve. It’s a tradition for people to solve the riddles during Chinese festivals. When the participants are immersed in the joy of solving riddles, we handed out each participant a set of materials for painting plaster rabbit statues. Rabbit God, Tu’erye in Chinese, is a deity of Chinese folk religion unique to Beijing, where his sculptures are traditionally crafted. The fairytale rabbit descended to a plague-stricken world and healed people. For his good deed, he is commemorated with a lovely image and receive thanks every year. Therefore, worshipping Lord Rabbit has become a typical custom observed in Beijing. After hearing the story, the participants couldn’t wait to start their painting. After their brain-storming imagination, dozens of the plaster sculptures were vividly presented. Another tradition of Mid-Autumn Festival is eating mooncakes. Today, participants got the opportunity to make mooncakes by themselves. This activity helped the international students better understand Chinese traditional culture and they all felt very relaxed during the whole process, which gave them a break from the digital world and travelled back to thousand years ago to experience the romance of ancient Chinese people. Students from ICTP-AP also enjoyed this activity and they felt more connected to each other after the celebration party.
