A social perception scheme for behavior planning of autonomous cars

Posted by in categories: robotics/AI, transportation

To navigate dynamic environments, autonomous vehicles (AVs) should be able to process all information available to them and use it to generate effective driving strategies. Researchers at the University of California, Berkeley, have recently proposed a social perception scheme for planning the behavior of autonomous cars, which could help to develop AVs that are better equipped to deal with uncertainty in their surrounding environment.

“My research has focused on how to design human-like driving behaviors for autonomous cars,” Liting Sun, one of the researchers who carried out the study, told TechXplore. “Our goal is to build AVs that do not only understand , but also perform in a similar way in multiple aspects, including , reasoning and action.”

Sun and her colleagues observed that human drivers tend to treat other vehicles as dynamic obstacles, often inferring additional information from their behavior on the road. This information is generally occluded environment information or physically undetectable social information.

Genetically engineered immune cells fight off deadly virus in mice

Posted by in categories: bioengineering, biotech/medical, genetics

Researchers may have demonstrated a novel way to protect us from some of the world’s deadliest viruses. By genetically engineering immune cells to make more effective antibodies, they have defended mice from a potentially lethal lung virus. The same strategy could work in humans against diseases for which there are no vaccines.

“It’s a huge breakthrough,” says immunologist James Voss of the Scripps Research Institute in San Diego, California, who wasn’t connected to the study.

Vaccines typically contain a disabled microbial invader or shards of its molecules. They stimulate immune cells known as B cells to crank out antibodies that target the pathogen. Not everyone who receives a vaccine gains protection, however. Some patients’ antibodies aren’t up to snuff, for instance. And researchers haven’t been able to develop vaccines against some microbes, such as HIV and the respiratory syncytial virus (RSV), which causes lung infections mainly in children and people with impaired immune systems.

Lilium’s full-sized electric jet flies for the first time

Posted by in category: transportation

Lilium first emerged in 2016 as an aviation startup with some very lofty ambitions, revealing plans to develop a five-seat electric aircraft that can take off vertically, switch to horizontal flight in mid-air and cover some sizable distances on each charge. The company has now taken a significant step toward achieving this goal, completing a flight of a full-scale prototype of its Lilium Jet for the very first time.

Exploring the scientific potential of the ATLAS Experiment at the High-Luminosity LHC

Posted by in categories: life extension, particle physics

The High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) is scheduled to begin colliding protons in 2026. This major improvement to CERN’s flagship accelerator will increase the total number of collisions in the ATLAS experiment by a factor of 10. To cope with this increase, ATLAS is preparing a complex series of upgrades including the installation of new detectors using state-of-the-art technology, the replacement of aging electronics, and the upgrade of its trigger and data acquisition system.

What discovery opportunities will be in reach for ATLAS with the HL-LHC upgrade? How precisely will physicists be able to measure properties of the Higgs boson? How deeply will they be able to probe Standard Model processes for signs of new ? The ATLAS Collaboration has carried out and released dozens of studies to answer these questions—the results of which have been valuable input to discussions held this week at the Symposium on the European Strategy for Particle Physics, in Granada, Spain.

“Studying the discovery potential of the HL-LHC was a fascinating task associated with the ATLAS upgrades,” says Simone Pagan Griso, ATLAS Upgrade Physics Group co-convener. “The results are informative not only to the ATLAS Collaboration but to the entire global community, as they reappraise the opportunities and challenges that lie ahead of us.” Indeed, these studies set important benchmarks for forthcoming generations of particle physics experiments.

Ultra-clean fabrication platform produces nearly ideal 2-D transistors

Posted by in categories: business, computing, engineering, particle physics

Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century. Recently discovered two-dimensional materials, which feature many superlative properties, have the potential to advance these technologies, but creating 2-D devices with both good electrical contacts and stable performance has proved challenging.

Researchers at Columbia Engineering report that they have demonstrated a nearly ideal transistor made from a two-dimensional (2-D) material stack—with only a two-atom-thick semiconducting layer—by developing a completely clean and damage-free process. Their method shows vastly improved performance compared to 2-D semiconductors fabricated with a conventional process, and could provide a scalable platform for creating ultra-clean devices in the future. The study was published today in Nature Electronics.
