A | (ECNS) -- A retired cultural event planner in China has turned to artificial intelligence to animate 71 historical oil paintings of Chinese railroad workers, producing two short documentaries that have drawn widespread attention on YouTube and rekindled public interest in a long-overlooked chapter of U.S. immigration history. Chen Huiping, who spent more than two decades organizing community cultural activities before taking up video editing as a retirement hobby, used AI-powered animation tools and archival photographs to recreate the perilous conditions faced by Chinese laborers during the Gold Rush era and the construction of the Transcontinental Railroad. The two films, Once Upon a Time in the West and The Bittersweet History of Chinese Railroad Workers, have earned widespread global acclaim. Adapting 71 detailed paintings by Chinese-American artist Mian Situ, Chen utilized AI animation and historical photos to recreate the scenes of Gold Rush migrants and the perilous construction of the Transcontinental Railroad. The films shed light on the often-overlooked contributions of early Chinese pioneers to U.S. nation-building. For Chen, who embraced video editing as a retirement hobby, the goal was to rescue these collective memories from obscurity. As she dynamically demonstrates: “Exploration and new beginnings never have an age limit; you just have to take that first step.”
。 Shares of Pfizer are in retreat on the first day of trading after the drug company said sales of its COVID-19 vaccine and its coronavirus treatment are weaker than it had expected and cut revenue projections by $9 billion for the year. Falling sales of both clipped sales in the second quarter, but Pfizer said in August that it expected a rebound in the second half of 2023. Shares of Pfizer slipped more than 1% before the opening bell Monday and Moderna, which is heavily reliant on the competing vaccine it makes, slid nearly 5%. Pfizer said Friday that global usage of Paxlovid is trending slightly above last year, but that it's still below expectations.The fall vaccination period just began and the New York City drugmaker said that it's too soon to get a handle on vaccination rates for the year.Full-year revenue for Paxlovid and Comirnaty is expected to be approximately $12.5 billion, short $9 billion of what it had expected. Pfizer is lowering its full-year revenue expectations for Paxlovid by approximately $7 billion. That number also accounts for delayed commercialization of the product, which was pushed to January 2024 from the company's previous expectation of commercialization in the second half of this year. Pfizer is also lowering its 2023 revenue expectations for Comirnaty by approximately $2 billion due to lower-than-expected vaccination rates.Pfizer Inc. now foresees 2023 revenue in a range of $58 billion to $61 billion, down from its prior forecast for $67 billion to $70 billion. It now projects full-year adjusted earnings between $1.45 and $1.65 per share due to lower-than-anticipated revenue for COVID-19-related products and inventory write-offs.That is short of the full-year revenue of $63.61 billion and earnings of $2.77 per share that Wall Street was expecting, and far short of the company's previous projections of per-share earning between $3.25 and $3.45. JPMorgan said the company's update solves an ongoing U.S. Paxlovid inventory debate and it anticipates the company's bigger-than-expected cuts to its sales projections will help put a floor under per-share earnings expectations for next year.。
