一 | Planes packed with summer travelers boosted Delta Air Lines to a $1.11 billion profit in the third quarter, and the carrier said Thursday that it expects revenue to keep rising into the holiday season.Profit was up 59% from a year earlier, as strong ticket sales — especially for premium seats and international flights — helped Delta shrug off higher labor costs.The Atlanta-based airline predicted ranges for fourth-quarter and full-year profit that mostly exceed Wall Street expectations.“I think we’re closing the year strong, and the holiday bookings that we see right now are pretty good,” CEO Ed Bastian said in an interview. “Domestic (travel) is solid, and international is really strong.”U.S. airlines are flying high as the travel recovery that began last year shows few signs of slowing down.Delta increased its passenger-carrying capacity an aggressive 16% and was able to fill all those extra seats. Travelers flew 64 billion miles on the airline in the quarter, a 17% increase, and they filled 88% of the seats on the average flight, a point higher than last summer.Revenue from ticket sales in the main cabin grew 12% — and 17% for premium seating. Money from Delta’s loyalty program soared 21%.The program, called SkyMiles, has become so popular that there are far more passengers hoping for upgrades to better seats than available seats. Lines can grow long at Delta lounges at busy airports like Atlanta and New York’s JFK.But when Delta announced changes to deal with the overcrowding last month — including basing elite frequent-flyer status purely on spending, and limiting lounge access for holders of Delta credit cards — the reaction from longtime customers was quick and brutal. Some vowed to switch airlines. Alaska Airlines and JetBlue fished for disgruntled Delta members by promising elite status in their programs. Even Bastian admitted the airline “ probably went too far.” Bastian has promised to modify the unpopular changes, but he hasn’t given any details yet.“We are working on that. We’ll be announcing something in the coming days,” Bastian said in the interview. He said he has received “a lot of feedback – everyone had their own ideas as to how we might restructure the program. Almost universally, people acknowledged that we needed to do something.” Delta's third-quarter profit, adjusted to exclude one-time items, was $2.03 per share, 8 cents better than forecast by analysts in a FactSet survey. Revenue rose 11% to $15.49 billion, also beating expectations.For the fourth quarter, Delta said revenue will rise as much as 11% from a year ago and it will earn between $1.05 to $1.30 per share. Analysts expected $1.09.The airline predicted that full-year profit will land between $6 and $6.25 per share after saying in June it would be at the top end of a $5-to-$6 range. The short-term outlook would be rosier if not for a recent pickup in jet fuel prices — although fuel is still much cheaper than it was a year ago. Bastian expressed confidence that Delta and other carriers can raise prices enough to cover any increase in fuel expense. Shares of Delta were virtually flat in morning trading.。

据介绍,DAMO LiON模型作为“AI安全员”协助医生阅片,既能精准识别原发性肝癌,更擅长揪出容易被忽视的肝转移。实验结果显示,AI模型识别出恶性肿瘤的准确率高于放射科医生。
当医生用AI模型协助阅片,用时减少了27%,而对恶性肿瘤的敏感性更提高了11.5%,有效减少漏诊;在AI协助下,初级医生能达到资深医生水平。

四 | 研究团队随后将AI模型实际部署到医院,参与日常阅片,当AI与医生初诊结论不一致时,病例会交给资深放射科医生复核,必要时升级至多学科团队(MDT)讨论。两个月内,AI共阅读1万多名患者的增强CT影像,辅助医生抓出15例原本被忽略的肝转移,推动改变了这些患者的治疗方案。据官方介绍,早在2017年,达摩院在行业内率先提出用AI识别医学影像中人眼难以察觉的细微病灶。目前已先后研发出基于平扫CT的胰腺癌筛查AI模型 DAMO PANDA、胃癌筛查AI模型DAMO GRAPE、肠癌筛查AI模型DAMO COCA等,相关成果三次登上《自然·医学》,进入国家药品监督管理局的创新通道,并获美国食品药品监督管理局(FDA)“突破性医疗器械”认定。
