It starts without warning--or rather, the warnings are there, but your ability to detect them exists only in hindsight. First you're sitting in the car with your son, then he tells you: "I cannot find my old self again." You think, well, teenagers say dramatic stuff like this all the time. Then he's refusing to do his homework, he's writing suicidal messages on the wall in black magic marker, he's trying to cut himself with a razor blade. You sit down with him; you two have a long talk. A week later, he runs home from a nighttime gathering at his friend's apartment, he's bursting through the front door, shouting about how his friends are trying to kill him. He spends the night crouching in his mother's old room, clutching a stuffed animal to his chest. He's 17 years old at this point, and you are his father, Dick Russell, a traveler, a former staff reporter for Sports Illustrated, but a father first and foremost.

ON JUNE 1st 2009, an Air France airliner travelling from Rio de Janeiro to Paris flew into a mid-Atlantic storm. Ice began forming in the sensors used by the aircraft to measure its airspeed, depriving the autopilot of that vital data. So, by design, the machine switched itself off and ceded control to the pilots. Without knowing their speed, and with no horizon visible in a storm in the dead of night, the crew struggled to cope. Against all their training, they kept the plane's nose pointed upward, forcing it to lose speed and lift.

The first thing that might come to mind thinking of drones is their military application. Unmanned flying weaponry, however, is not a new approach. In the 1860s, balloons loaded with explosives and sent with the prevailing winds towards enemy targets, were used as the first drones. Today, they have become such an innovative technology that its use has extended to the civilian and commercial sector, becoming a part of our everyday life. Unmanned aircraft systems (UAS) or by the public referred as drones, have the potential to solve problems, improve safety and save costs across a number of industries, throughout the developing world and in disaster relief scenarios.

Ford Motor Co. is shifting all of its North American small-car production to Mexico, Chief Executive Mark Fields said Wednesday. "Over the next two to three years, we will have migrated all of our small-car production to Mexico and out of the United States," Fields said. Ford currently makes its Fiesta subcompact in Mexico, but its Focus and C-Max small cars are made in suburban Detroit. Making them in Mexico would boost company profits because of low wages there. The company is building a 1.6-billion assembly plant in San Luis Potosi, Mexico.

Inbenta, a San Mateo, CA-based enterprise-grade artificial intelligence solutions, raised 12m in Series B funding. The round was led by Level Equity, with participation from Amasia and Scale Capital through its Amérigo Chile fund. In conjunction with the funding, founder and partner George McCulloch and Amasia chairman Ramanan Raghavendran joined Inbenta's board of directors. The company intends to use the funds to expand sales and marketing, and to further drive product development for its technology. Founded in 2005 by Jordi Torras, CEO, Inbenta has developed natural language processing (NLP) technology that powers search, chatbots, and self-service solutions for customer support and e-commerce.

"Inbenta was founded in 2005 with a vision of leveraging artificial intelligence in an entirely new manner to transform how companies and customers interact," said Jordi Torras, founder and CEO, Inbenta. "That vision has been realized, and now Inbenta is in a period of dramatic and profitable growth including global expansion into 23 countries and support for over 20 languages. This Series B financing will help bring our technology to a much larger group of demanding customers who need enterprise-grade solutions, and to further drive the innovation that underpins our technology." The funding will be used to expand sales and marketing, and to further drive product development for Inbenta's industry-leading natural language processing (NLP) technology that powers search, chatbots, and self-service solutions for customer support and e-commerce. Inbenta's products are now used by over 200 customers around the world, including Ticketmaster, B&H, CA Technologies and 8x8 to enhance customer engagement, increase retention, and drive sales.

Ford Motor Co. F -1.53 % made its latest plea for investors to view the auto maker more like a Silicon Valley company, promising lofty returns on future ventures while warning near-term profit will be pinched by deep investment. The Dearborn, Mich., auto maker told investors on Wednesday that its new business services unit eventually will deliver 20% margins, two-and-a-half-times its core auto-making operation. It updated its plans for venturing into robo-taxis, electric car and other transportation services like bike sharing and shuttle vans. Ford's share price has declined while Chief Executive Mark Fields has been at the helm, despite delivering record operating profit. The focus under Mr. Fields--who took over in 2014 after Alan Mulally spent nearly a decade on initiatives that had Ford getting back to basics--has been on winning a technology race with rivals including General Motors Co. GM -0.71 % and Toyota Motor Corp. TM -1.04 % The new strategy will be costly and risky.

Moving to crack down on scam artists, Los Angeles County supervisors voted Tuesday to require immigration consultants working in unincorporated areas of the county to be licensed. The consultants, sometimes referred to as "notarios," are not attorneys. But some offer legal services and charge high rates. Because notary publics in Latin America are roughly equivalent to lawyers, immigrants often do not realize that in the United States they are only authorized to witness signatures and authenticate documents, said Supervisor Hilda Solis, who proposed the enforcement program along with Supervisor Sheila Kuehl. "I've spoken with numerous families who have been for years paying dollar after dollar without making any progress on their immigration matters," Solis said.

Imagine infusing thousands of wireless devices into your brain, and using them to both monitor its activity and directly influence its actions. It sounds like the stuff of science fiction, and for the moment it still is – but possibly not for long. Brain research is on a roll at the moment. And as it converges with advances in science and technology more broadly, it's transforming what we are likely to be able to achieve in the near future. Spurring the field on is the promise of more effective treatments for debilitating neurological and psychological disorders such as epilepsy, Parkinson's disease and depression.

In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to the availability of vehicles and strives to achieve balanced routes. We study an adaptation of the model for the multi-vehicle covering tour problem, in which a set of locations must be visited, whereas another subset must be close enough to the planned routes. It constitutes an NP-complete integer programming problem. Suboptimal solutions are obtained with several heuristics, some adapted from the literature and others developed by us. We solve some adapted instances from TSPLIB and an instance with real data, the former being compared with results from literature, and latter being compared with empirical data.
