In a recent study, scientists from Johns Hopkins University in the United States have developed a new artificial intelligence (AI) model called "Differential Mapping Operator Learning" (DIMON), which can solve complex partial differential equations on personal computers, thousands of times faster than before, and is expected to "show its talents" in the fields of aerospace, automobiles and medicine. Related papers were published in the journal Nature Computational Science published on the 9th. (Science and Technology Daily)New players run into REITs to upgrade their quality and expand their scope to a higher level. Several head public offerings have begun to test the REITs field. Some fund companies have issued three new products in less than three months, and small and medium-sized public offerings are also eager to try ... Recently, the new speed in REITs field has not diminished. In December, five products have been launched, which is a new high for a single month in the year. The number and scale of new REITs products have reached a record high this year. In the interview and investigation, the reporter found that "making efforts to serve the real economy", "conforming to the market investment demand under the low interest rate environment" and "the future development space of REITs market is broad" have become an important driving force for many fund companies to actively deploy such products.

According to a paper published in Nature magazine on the 10th, Google's latest generation of quantum chips has achieved a breakthrough in error correction capability, that is, the error is suppressed below a critical threshold. This quantum error correction function is considered as a necessary condition to realize the practical application of quantum computing in the future. After the performance of the chip is expanded, it may be able to promote the operation requirements of large-scale fault-tolerant quantum computing. (Science and Technology Daily)
