'Alibaba City Brain' in Hangzhou, China - Created in collaboration with more than a dozen companies including Foxconn and HTC, Alibaba's Brain 1.0 uses deep-learning and AI to track commutes, purchases, social media and other interactions for optimizing city functions such as managing Hangzhou's traffic lights to keep transportation moving and accidents down, or identifying potentially criminal behavior.

As the news media again turns its attention to Dominique Strauss-Kahn, the former leader of the International Monetary Fund who is on trial in France on accusations that he participated in a prostitution ring, the woman who accused him of sexual assault in New York City in 2011 has quietly resumed her life, this time behind the counter of a West African restaurant in the Bronx.

Nafissatou Diallo, the hotel housekeeper who accused Mr. Strauss-Kahn of attacking her in his suite at the Sofitel Hotel, opened the storefront restaurant, Chez Amina Restaurant, on Boston Road last year, according to a worker there. A Facebook page for the restaurant says it officially opened on May 16. Chez Amina serves burgers, salads and soups along with savory West African specialties like fish and rice stew, from 5 a.m. to 3 a.m. every day.

Its regular customers include taxi drivers, who carried out steaming silver tins, and West African immigrants from the neighborhood who settled into platters at tables outfitted with A1 steak sauce and white porcelain sugar bowls. “Everything is good,” said Cisse Elhe, 52, an immigrant from Senegal who orders from the restaurant every week.

For most of Tuesday, Ms. Diallo was nowhere to be seen after an article about the restaurant appeared in the French media. A half-dozen journalists camped out for hours in Chez Amina’s red leather banquettes and wooden chairs, hoping for a glimpse of Ms. Diallo.
