Home work triggers demand jump for chips, laptops and network goods

SEOUL/TOKYO (Reuters) – With more employees working from home to help slow the spread of the coronavirus, demand is surging for laptops and network peripherals as well as components along the supply chain such as chips, as companies rush to build virtual offices.

Many firms have withdrawn earnings forecasts, anticipating a drop in consumer demand and economic slump, but performance at electronics retailers and chipmakers is hinting at benefits from the shift in work culture.

Over the past month, governments and companies globally have been advising people to stay safe indoors. Over roughly the same period, South Korea – home of the world’s biggest memory chip maker, Samsung Electronics Co Ltd – on Monday reported a 20% jump in semiconductor exports.

Pointing to further demand, nearly one in three Americans have been ordered to stay home, while Italy – where deaths have hit 5,476 – has banned internal travel. Worldwide, the flu-like virus has infected over 300,000 people and led to almost 15,000 deaths since China first reported the outbreak in December.

“With more people working and learning from home during the outbreak, there has been rising demand for internet services … meaning data centres need bigger pipes to carry the traffic,” said analyst Park Sung-soon at Cape Investment & Securities.

A South Korean trade ministry official told Reuters that cloud computing has boosted sales of server chips, “while an increase in telecommuting in the United States and China has also been a main driver of huge server demand.”

In Japan, laptop maker Dynabook reported brisk demand which it partly attributed to companies encouraging teleworking. Rival NEC Corp said it has responded to demand with telework-friendly features such as more powerful embedded speakers.

Australian electronics retailer JB Hifi Ltd also said it saw demand “acceleration” in recent weeks from both commercial and retail customers for “essential products they need to respond to and prepare” for the virus, such as devices that support remote working as well as home appliances.

CHINA LEAD

China is leading chip demand, analysts said, as cloud service providers such as Alibaba Group Holding Ltd, Tencent Holdings Ltd and Baidu Inc quickly responded to the government’s effort to contain the virus.

“Cloud companies opened their platforms, allowing new and existing customers to use more resources for free to help maintain operations,” said analyst Yih Khai Wong at Canalys.

“This set the precedent for technology companies around the world that offer cloud-based services in their response to helping organisations affected by coronavirus.”

China’s cloud infrastructure build-up has helped push up chip prices, with spot prices of DRAM chips rising more than 6% since Feb. 20, showed data from price tracker DRAMeXchange.

UBS last week forecast average contract prices of DRAM chips to rise as much as 10% in the second quarter from the first, led by a more than 20% jump in server chips.

It said it expects DRAM chips to be modestly under supplied until the third quarter of 2021, with demand from server customers rising 31% both in 2020 and 2021.

SUPPLY DISRUPTION

Concerns over supply disruption has also contributed to a price rise.

“You’ve got lots of OEMs and systems integrators in the global market who have intense demand for memory now,” said Andrew Perlmutter, chief strategy officer at ITRenew, a company that buys and reworks used data centre equipment for resale.

“Nobody is shutting down their factories – it is still production as normal – but people worry about memory supply in particular, so they want to get out ahead of production.”

About 69% of electronics manufacturers have flagged possible supplier delays averaging three weeks, showed a poll on March 13 by industry trade group IPC International.

Half of those polled expected business to normalise by July, and nearly three-quarters pointed to at least October.

Circus tiger escapes during show in China, but dies after being captured and sent to zoo

  • Two people from the circus have been detained after the animal managed to get out of its cage and run towards nearby cornfields on Friday evening
  • It was found the next morning and police used a tranquilliser to subdue the tiger but it died on the way to the zoo, which believes it had been hit by a car

A circus tiger that escaped from its cage during a show in central China was captured by police after an overnight search, but died while it was being transported to a nearby zoo, according to media reports.

Two people from the circus where the tiger was raised in the county of Yuanyang, Henan province, have been detained, Beijing Youth Daily reported, without elaborating. It said the tiger escaped during the circus’ first public show, which had not been registered with the local authorities.

The tiger was part of a performance for a local school on Friday evening when it managed to get out of its cage and run towards nearby cornfields.

A video posted by news site Thepaper.cn shows the moment it escaped from the cage, with its handlers using sticks to try to coax the animal back inside. The scene is chaotic, as people scream and run from the venue.

The police were called in, and officers used drones, police dogs and thermal imaging equipment to hunt for the tiger, according to the local government.

The authorities also put out an emergency advisory telling residents to stay indoors and contact police if they had any information on the tiger’s whereabouts.

It was spotted the following morning, and a tranquilliser dart was used to subdue the animal at about 10.30am on Saturday. The tiger was then transported to a zoo in the city of Xinxiang.

According to one of its zookeepers, the animal had already died by the time it was delivered to the zoo, China Youth Daily reported on Sunday.

The \jsq, surnamed Feng, said the tiger was hit by a car after it escaped and may have sustained internal injuries. The zoo is conducting an autopsy.

Thousands of social media users expressed their sympathy for the tiger’s plight, saying it must have suffered greatly, with many people calling for animal circuses to be banned in China.
“Tigers don’t belong in cages, they belong in the wilderness,” one person wrote on microblog site Weibo.

Chinese scientists hail ‘incredible’ stealth breakthrough that may blind military radar systems

  • Researchers at academy of science believe electromagnetic wave model is key that will herald new era in radar detection and avoidance for military ships and aircraft

Chinese scientists have achieved a series of breakthroughs in stealth materials technology that they claim can make fighter jets and other weaponry lighter, cheaper to build and less vulnerable to radar detection.
Professor Luo Xiangang and colleagues at the Institute of Optics and Electronics, Chinese Academy of Sciences in Chengdu, Sichuan province, said they had created the world’s first mathematical model to precisely describe the behaviour of electromagnetic waves when they strike a piece of metal engraved with microscopic patterns, according to a statement posted on the academy’s website on Monday.
With their new model and breakthroughs in materials fabrication, they developed a membrane, known as a meta surface, which can absorb radar waves in the widest spectrum yet reported.
At present, stealth aircraft mainly rely on special geometry – their body shape – to deflect radar signals, but those designs can affect aerodynamic performance. They also use radar absorbing paint, which has a high density but only works against a limited frequency spectrum.

In one test, the new technology cut the strength of a reflected radar signal – measured in decibels – by between 10 and nearly 30dB in a frequency range from 0.3 to 40 gigahertz.

A stealth technologist from Fudan University in Shanghai, who was not involved in the work, said a fighter jet or warship using the new technology could feasibly fool all military radar systems in operation today.

“This detection range is incredible,” the researcher said. “I have never heard of anyone even coming close to this performance. At present, absorbing technology with an effective range of between 4 and 18 GHz is considered very, very good.”

China’s new radar system could spot stealth aircraft from at long range

The lower the signal frequency, the longer a radar’s detection range. But detailed information about a moving target can only be obtained with higher frequency radio waves. Militaries typically use a combination of radars working at different frequencies to establish lines of defence.

The Medium Extended Air Defence System, Nato’s early warning radar, operates at a frequency range of 0.3 to 1 GHz. The American Terminal High Altitude Area Defence system, the missile defence radar that caught Beijing’s attention when it was deployed in South Korea in 2017, operates at frequencies around 10 GHz.

Some airports use extremely short-range, high-frequency radars running at 20 GHz or above to monitor vehicle and plane movements on the ground, but even they might not be able to see a jet with the new stealth technology until it is overhead.

“Materials with meta surface technology are already found on military hardware in China, although what they are and where they are used remains largely classified,” the Fudan researcher said.

Luo and his colleagues could not be reached for comment. But according to the academy’s statement and a paper the team published in the journal Advanced Science earlier this year, the stealth breakthroughs were based upon a discovery they made several years ago.

They found that the propagation pattern of radio waves – how they travelled – in extremely narrow metallic spaces was similar to a catenary curve, a shape similar to that assumed by chains suspended by two fixed points under their own weight.

Inspired by catenary electromagnetics, the team developed a mathematical model and designed meta surfaces suitable for nearly all kinds of wave manipulation.
These included energy-absorbing materials for stealth vehicles and antennas that can be used on satellites or military aircraft.
Zhu Shining, a professor of physics specialising in meta materials at Nanjing University, said the catenary model was a “novel idea”.
“The Institute of Optics and Electronics in Chengdu has conducted long-term research in this area which paved a solid foundation for their discoveries. They have done a good job,” Zhu said.
“Scientists are exploring new features of metal materials, some of them are already in real-life applications.”

BEIJING, Jan. 15 (Xinhua) — Peng Liyuan, the wife of Chinese President Xi Jinping, attended a performance with Jenni Haukio, wife of Finnish President Sauli Niinisto, on Tuesday.

The show, which included poetry reading and musical performances, was held in the stylish bookstore Page One situated in the Qianmen area, a significant symbol of old Beijing.

After having strolled around the bookstore and learning about the history of the bookstore and the surrounding block, Peng and Haukio enjoyed wonderful performances on the top floor. Peng also briefed Haukio on the history and recent renovation of the historic district of Dashilar.

During the show, students majoring in Finnish read Haukio’s award-winning poems, catching her by surprise.

Young ladies dressed in ancient costumes sang traditional Chinese poems with the accompaniment of piano and Chinese zither, a traditional Chinese instrument.

The performance ended with a violinist and a pianist playing a piece work composed by Finnish composer Jean Sibelius.

The show was performed by teachers and students from the Beijing Foreign Studies University and the China Conservatory of Music.

Haukio is in Beijing accompanying President Niinisto who is paying a state visit to China from Sunday to Wednesday.
