AI can solve partial differential equations thousands of times faster than before, and partial differential equations play an important role in engineering and science. 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.

Under the two-way catalysis of supply and demand, China enterprises are actively participating in global market competition and paying attention to brand/culture/service going to sea.
A new generation of quantum chips has achieved a breakthrough in error correction capability. 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.Xie Yunliang, macro chief analyst of Cinda Securities, said that historically, the establishment of a "moderately loose" policy orientation needs to meet two major conditions, namely, the domestic pressure to stabilize prices is high and the foreign Federal Reserve is in a loose cycle.

In November, the weather gradually turned cold, and the downstream market demand dropped slightly. Most provinces in the north have entered the stage of winter peak-shifting and kiln-stopping, and the kiln-stopping rate is above 80%. Under the background of improving supply and demand in the industry, cement enterprises continue to push up cement prices. 2) Consumer building materials: The retail end continued to improve month on month. In October, the retail sales of building and decoration materials decreased by 5.8% year-on-year and increased by 4.9% quarter-on-quarter. Recently, with the stabilization of commercial housing sales, the demand for consumer building materials has improved. 3) Glass fiber: the price of roving rose slightly at the end of the month, and the price of electronic yarn was temporarily stable. In November, the demand for wind power yarn and thermoplastic yarn was stable, but the demand for traditional building materials was still under pressure, which led to the general demand for roving. There are resumption of production and new ignition production lines within the month, and the annual production capacity has increased; Near the end of the month, glass fiber enterprises issued a notice of re-pricing roving and products. It will take some time for the new price to land, but it will have a certain driving effect on demand and price in the short term. 4) Float glass: at the end of the year, work will continue to support the market demand and the inventory of enterprises will be improved. In November, work was rushed to support the demand of float glass terminal, but the middle and lower reaches mainly digested the previous inventory, and the purchasing enthusiasm declined. In the context of the contradiction between supply and demand in the industry, the production capacity has been significantly reduced, and the inventory pressure of float glass enterprises has improved. Suggested attention: Beixin Building Materials, CONCH, China Jushi, etc.
