The states said the automakers had failed to take adequate steps to address the alarming rate of theft and urged them to accelerate the implementation of the software upgrade and provide free alternative protective measures for owners whose cars cannot support the software upgrade.

WASHINGTON, March 23 (Reuters) - Treasury Secretary Janet Yellen said on Thursday the United States was looking at ways to strengthen its sanctions against Iran, but acknowledged the sanctions had not resulted in the behavioral or policy changes Washington desires from Tehran.

Novak Djokovic said he had no regrets about missing tournaments at Indian Wells and Miami due to his Covid-19 vaccination status but hoped that he would be allowed into the United States later this year for the US Open.

Walmart has been investing heavily in automation over the past few years, partnering with automation companies such as Knapp to help it cut down the number of steps it takes employees to process e-commerce orders to five from 12, which has been implemented at its Pedricktown, New Jersey location, for instance.

The spokesperson said impacted workers would be paid for 90 days to find jobs at other facilities, including those in Joliet, Illinois, and Lancaster, Texas, where the company has opened up new high-tech e-commerce distribution centers.

"CUDA Quantum will do the same for quantum computing, enabling domain scientists to seamlessly integrate quantum into their applications and gain access to a new disruptive computing technology," said Tim Costa, Nvidia's director of HPC and quantum.

On a post-earnings call in February, Walmart CEO Doug McMillon said he was 'most excited about the automation opportunity we have' with plans to increase investments in automation technology as part of its more than $15-billion capital expenditure budget this year.

About 200 workers at Pedricktown, New Jersey, and hundreds of others at Fort Worth, Texas; Chino, California; Davenport, Florida; and Bethlehem, Pennsylvania were let go due to a reduction or elimination in evening and weekend shifts, the spokesperson said.

March 21 (Reuters) - Nvidia Corp, the computing company powering the bulk of artificial intelligence, is positioning itself as a key player in quantum computing with the launch of new software and hardware.

'We recently adjusted staffing levels to better prepare for the future needs of customers,' Walmart said in a statement, adding that it would work closely with affected associates to find jobs at other locations.

For the past several years the council has been divided over how to deal with Pyongyang. Russia and China, veto powers along with the United States, Britain and France, have said more sanctions will not help and want such measures to be eased.

The program would help run the algorithm across quantum and classical computers depending on which system is most efficient in solving the problem. On Tuesday at its developer conference GTC, Nvidia unveiled CUDA Quantum, a platform for building quantum algorithms using popular classical computer coding languages C++ and python.

While quantum computers could potentially speed up some calculations millions of times faster than the fastest supercomputer, it is still uncertain when that would happen. And even when they become good enough to be useful, they would have to be paired with powerful digital computers to operate, said Sivan.

Thomas-Greenfield said lifting U.N. sanctions would reward Pyongyang "for doing nothing to comply with Security Council resolutions." She accused Pyongyang of depriving North Koreans of needed humanitarian assistance.

UNITED NATIONS, March 20 (Reuters) - The United States, China and Russia argued during a United Nations Security Council meeting on Monday over who was to blame for spurring North Korea's dozens of ballistic missile launches and development of a nuclear weapons program.

China and Russia blamed joint military drills by the United States and South Korea for provoking Pyongyang while Washington accuses Beijing and Moscow of emboldening North Korea by shielding it from more sanctions.
