China condemns attack on HK govt official in London

Feb 26: Looking out over the world’s largest cricket stadium, the seats jammed with more than 100,000 people, India’s prime minister heaped praise on his American visitor.

“The leadership of President Trump has served humanity,” Prime Minister Narendra Modi said Monday, highlighting Trump’s fight against terrorism and calling his 36-hour visit to India a watershed in India-U.S. relations.

The crowds cheered. Trump beamed.

“The ties between India and the U.S. are no longer just any other partnership,” Modi said. “It is a far greater and closer relationship.”

India, it seems, loves Donald Trump. It seemed obvious from the thousands who turned out to wave as his motorcade snaked through the city of Ahmedabad, and from the tens of thousands who filled the city’s new stadium. It seemed obvious from the hug that Modi gave Trump after he descended from Air Force One, and from the hundreds of billboards proclaiming Trump’s visit.

But it’s not so simple.

Because while Trump is genuinely popular in India, his clamorous and carefully choreographed welcome was also about Asian geopolitics, China’s growing power and a masterful Indian politician who gave his American visitor exactly what he wanted.

Modi “is doing this not necessarily because he loves Trump,” said Tanvi Madan, the director of the India Project at the Brookings Institution in Washington, D.C. “It’s very much about Trump as the leader of the U.S. and recognizing what it is that Trump himself likes.”

Trump likes crowds — big crowds — and the foot soldiers of India’s political parties have long known how to corral enough people to make any politician look popular. In a city like Ahmedabad, the capital of Modi’s home state of Gujarat and the center of his power base, it wouldn’t take much effort to fill a cavernous sports stadium. It was more surprising that a handful of seats remained empty, and that some in the stands had left even before Trump had finished his speech.

For India, good relations with the U.S. are deeply important: They signal that India is a serious global player, an issue that has long been important to New Delhi, and help cement an alliance that both nations see as a counterweight to China’s rise.

“For both countries, their biggest rival is China,” said John Echeverri-Gent, a professor at the University of Virginia whose research often focuses on India. “China is rapidly expanding its presence in the Indian Ocean, which India has long considered its backyard and its exclusive realm for security concerns.”

“It’s very clearly a major concern for both India and the United States,” he said.

Trump isn’t the first U.S. president that Modi has courted. In 2015, then-President Barack Obama was the first American chief guest at India’s Republic Day parade, a powerful symbolic gesture. Obama also got a Modi hug, and the media in both countries were soon writing about the two leaders’ “bromance.”

Trump is popular in India, even if some of that is simply because he’s the U.S. president. A 2019 Pew Research Center poll showed that 56% of Indians had confidence in Trump’s abilities in world affairs, one of only a handful of countries where he has that level of approval. But Obama was also popular: Before he left office, he had 58% approval in world affairs among Indians.

The Pew poll also indicated that Trump’s support was higher among supporters of Modi’s Hindu nationalist party.

That’s not surprising. Both men have fired up their nationalist bases with anti-Muslim rhetoric and government policies, from Trump’s travel bans to Modi’s crackdown in Kashmir, India’s only Muslim-majority state.

And Trump’s Indian support is far from universal. Protests against his trip roiled cities from New Delhi to Hyderabad to the far northeastern city of Gauhati, although those demonstrations were mostly overshadowed by protests over a new Indian citizenship law that Modi backs.

Modi, who is widely popular in India, has faced weeks of protests over the law, which provides fast track naturalization for some foreign-born religious minorities — but not Muslims. While Trump talked about ties with India on Tuesday, Hindus and Muslims fought in violent clashes that left at least 10 people dead over two days.

In some ways, Modi and Trump are powerful echoes of each other.

They have overlapping political styles. Both are populists who see themselves as brash, rule-breaking outsiders who disdain their countries’ traditional elites. Both are seen by their critics as having authoritarian leanings. Both surround themselves with officials who rarely question their decisions.

But are they friends?

Trump says yes. “Really, we feel very strongly about each other,” he said at a New Delhi press briefing.

But many observers aren’t so sure.

“The question is how much of this is real chemistry, as opposed to what I’d call planned chemistry” orchestrated for diplomatic reasons, said Madan. “It’s so hard to know if you’re not in the room.”

Certainly, Modi understands America’s importance to India. While the two countries continue to bicker about trade issues, the prime minister organized a welcome that impressed even India’s news media, which have watched countless choreographed mass political rallies.

“There is no other country for whose leader India would hold such an event, and for which an Indian prime minister would lavish such rhetoric,” the Hindustan Times said in an editorial.

“The spectacle and the sound were worth a thousand agreements.”

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Boston, Jun 7: Dozens of scientists doing research funded by Mark Zuckerberg say Facebook should not be letting President Donald Trump use of the social media platform to spread both misinformation and incendiary statements.

The researchers, including 60 professors at leading US research institutions, wrote a letter to the Facebook CEO on Saturday asking that he consider stricter policies on misinformation and incendiary language that harms people," especially during the current turmoil over racial injustice.

The letter calls the spread of deliberate misinformation and divisive language the researchers' goal of using technology to prevent and eradicate disease, improving childhood education and reform the criminal justice system.

The researchers' mission "is antithetical to some of the stances that Facebook has been taking, so we're encouraging them to be more on the side of truth and on the right side of history as we've said in the letter, said Debora Marks of Harvard Medical School, one of three professors who organized the letter.

The other organisers are Martin Kampmann of the University of California-San Francisco and Jason Shepherd of the University of Utah.

All have grants from a Chan Zuckerberg Initiative program working to prevent, cure and treat neurodegenerative disorders including Alzheimer's and Parkinson's disease. The initiative is run by Zuckerberg and his wife, Priscilla Chan.

They said the letter had more than 160 signatories. Shepherd said about 10% are employees of Chan Zuckerberg foundations.

The letter objects specifically to Zuckerberg's decision not to at least flag as a violation of Facebook's community standards Trump's post that stated when the looting starts, the shooting starts after unrest in Minneapolis over the videotaped killing of George Floyd, a black man, by a white police officer.

The letter's authors called the post a clear statement of inciting violence.

Twitter had both flagged and demoted a Trump tweet using the same language.

The Associated Press emailed the Chan Zuckerberg Initiative press office for comment. It did not immediately respond.

Some Facebook employees have publicly objected to Zuckerberg's refusal to take down or label misleading or incendiary posts by Trump or other politicians. But Zuckerberg who controls a majority of voting shares in the company has so far refused.

On Friday, Zuckerberg said in a post that he would review potential options for handling violating or partially-violating content aside from the binary leave-it-up or take-it-down decisions I know many of you think we should have labeled the President's posts in some way last week, he wrote.

"Our current policy is that if content is actually inciting violence, then the right mitigation is to take that content down not let people continue seeing it behind a flag. There is no exception to this policy for politicians or newsworthiness.
