Spiking neural networks (SNNs) capture the most important aspects of brain information processing. They are considered a promising approach for next-generation artificial intelligence. However, the biggest problem restricting the development of SNNs is the training algorithm.
To solve this problem, a research team led by Prof. Zeng Yi from the Institute of Automation of the Chinese Academy of Sciences has proposed backpropagation (BP) with biologically plausible spatiotemporal adjustment for training deep spiking neural networks.
The associated study was published in Patterns on June 2.
One of the myriad issues with hydrogen as a clean energy source is infrastructure, as it’s very expensive to move around and store an extremely explosive gas. Toyota and its subsidiary Woven Planet believe they may have a solution with a new portable hydrogen cartridge prototype. The idea is that they can be filled up at a dedicated facility, transported where needed, then returned when you receive your next shipment.
The cartridges would be relatively small at 16 inches long, 7 inches in diameter and about 11 pounds in weight. Toyota calls them “portable, affordable, and convenient energy that makes it possible to bring hydrogen to where people live, work, and play without the use of pipes… [and] swappable for easy replacement and quick charging.”
They could be useful for “mobility [i.e. hydrogen cars], household applications, and many future possibilities we have yet to imagine,” Toyota said. It didn’t mention any specific uses, but it said that “one hydrogen cartridge is assumed to generate enough electricity to operate a typical household microwave for approximately 3–4 hours.”
DETROIT (AP) — More than 750 Tesla owners have complained to U.S. safety regulators that cars operating on the automaker’s partially automated driving systems have suddenly stopped on roadways for no apparent reason.
The National Highway Traffic Safety Administration revealed the number in a detailed information request letter to Tesla that was posted Friday on the agency’s website.
The 14-page letter dated May 4 asks the automaker for all consumer and field reports it has received about false braking, as well as reports of crashes, injuries, deaths and property damage claims. It also asks whether the company’s “Full Self Driving” and automatic emergency braking systems were active at the time of any incident.

DeLorean released images and information on its upcoming 2024 electric car.
DeLorean is unapologetically human. A New Energy mobility brand.
We have a clear vision of our future, knowing it does not represent today. The DMC-12 was never meant to be a static interpretation of the brand, the brand would constantly evolve. Our icons are reimagined. DMC is and always was in constant evolution. An Icon is validated over time but to constantly reimagine mobility allows new icons to come into existence.
DeLorean is a legacy mobility company focused on redefining human connections through creative technologies.
Power-hungry, fossil-fuel dependent Japan has successfully tested a system that could provide a constant, steady form of renewable energy, regardless of the wind or the sun.
For more than a decade, Japanese heavy machinery maker IHI Corp. has been developing a subsea turbine that harnesses the energy in deep ocean currents and converts it into a steady and reliable source of electricity. The giant machine resembles an airplane, with two counter-rotating turbine fans in place of jets, and a central ‘fuselage’ housing a buoyancy adjustment system. Called Kairyu, the 330-ton prototype is designed to be anchored to the sea floor at a depth of 30–50 meters (100−160 feet).
Tested in one of the world’s strongest ocean currents, a prototype generator could herald the start of a new stream of renewable energy.
Tesla CEO #elonmusk has said that his company will not put a manufacturing plant in India until it is first allowed to sell, and service imported Tesla cars in the country. When a Twitter asked Musk about #Tesla’s plans to put up a manufacturing plant in India, #Musk responded, “Tesla will not put a manufacturing plant in any location where we are not allowed first to sell and service #cars.”
#India and Telsa haven’t reached an understanding regarding import duties and setting up of the manufacturing plant by Tesla in the #country.

Ford Motor Company recently filed a patent for a combustion engine that will run on hydrogen, Motor1 reports. The patent isn’t like your normal hydrogen-powered vehicle which uses a propulsion system that converts energy stored as hydrogen to electricity via a fuel cell. The patent Ford filed is for a turbocharged combustion engine that runs on hydrogen.
Muscle Cars and Truck, which initially discovered and reported on the patent, noted that on paper, Ford’s engine should be capable of operating across a wide range of air/fuel lambda, which is the Greek letter used to represent a fuel’s stoichiometric value as 1.00, with values depending on torque demands. MCT also noted that internal exhaust gas recirculation and valve timing will be used to control combustion.
MCT quickly touched upon the importance of the stoichiometric value of a fuel, which is the ratio by which all of the fuel is mixed with all of the oxygen to produce a competitive burn. Notably, Ford’s new method of turbocharged hydrogen will explore lambda values in excess of 2.00. This means that the new engine would be able to operate in an extremely lean state and use more than double the amount of air required for the stoichiometric combustion of hydrogen.

Limited mileage range and rare mineral mining have been sticking points for electric vehicle batteries, but Tesla is working on a design to last 100 years.
