Following the creation of the first cryptocurrency Bitcoin (BTC) in 2009, other cryptocurrencies such as Ethereum (ETH) and Ripple (XRP), followed suit to bring further attention to blockchain technology.
But there’s a lot of potential for the blockchain. According to recent research led by Vida J. Morkunas of Lulea University of Technology, Sweden and published by the Kelly School of Business, Indiana University:
“Emerging technologies regularly serve as enabling forces for economic, social, and business transformation.. [B]lockchain placed among the top five technology trends in 2018… Therefore, blockchain is predicted to challenge existing business models and offer opportunities for new value creation.”
As you probably know, the blockchain is a public digital ledger and a record-keeping technology. All transactions that have written in blocks are immutable, and information can never be erased. Furthermore, they are transparent to all parties in
People’s exposure to environmental noise dropped nearly in half during the early months of the coronavirus pandemic, according to University of Michigan researchers who analyzed data from the Apple Hearing Study.
Researchers at U-M’s School of Public Health and Apple Inc. looked at noise exposure data from volunteer Apple Watch users in Florida, New York, California and Texas. The analysis, one of the largest to date, included more than a half million daily noise levels measured before and during the pandemic.
Daily average sound levels dropped approximately 3 decibels during the time that local governments made announcements about social distancing and issued stay-at-home orders in March and April, compared to January and February.
“That is a huge reduction in terms of exposure and it could have a great effect on people’s overall health outcomes over time,” said Rick Neitzel, associate professor of environmental health sciences at U-M’s School of Public
In the two weeks since it was launched, North Carolina’s COVID-19 exposure app, SlowCOVIDNC, has been downloaded more than 100,000 times.
But Sam Gibbs, the deputy secretary for technology and operations at the N.C. Department of Health and Human Services, said the app shouldn’t necessarily be judged by the absolute number of North Carolinians who download it.
That’s because the state, he said, is being very specific about who it is marketing the app to. Rather than invest in widespread and expensive marketing to all residents in the state, DHHS is targeting the app toward specific populations.
For example, a large majority of people who have downloaded SlowCOVIDNC are students in the UNC System, community colleges or private universities in the state.
“It is not an overall number (of downloads) we are looking for — we are trying to get concentrations in places that” are at high risk, Gibbs
The iPhone 11 Pro’s triple camera array takes some of the best images you can get from a phone, and even the iPhone SE‘s single camera captures amazing images that belie its affordable price. But hidden inside these phones, specifically ones launched after the iPhone 6, is a creative trick that lets you transform your everyday images into dreamy long exposure shots.
A long exposure photograph is any image where the shutter has been intentionally left open long enough to blur the motion in the image. Look up pictures of waterfalls and you’ll undoubtedly see images where the raging torrent of water has been smoothed out into this otherworldly flow — that’s a long exposure image.

“The combination of the two factors makes Biden a close contact, even if the letter of the law doesn’t consider him one,” Dr. Marr said.
Mr. Biden tested negative for the virus twice on Friday, the Biden campaign said. He was not tested on Saturday and left his home for part of the day, going to a theater to participate in a virtual event and a church to attend Mass. The campaign announced his latest negative test result on Sunday night. Pressed on CNN about the frequency of Mr. Biden’s coronavirus tests, Ms. Sanders said the candidate was “tested before we travel.”
In the coming days, the Biden campaign is aiming to balance health precautions with continued travel in Florida on Monday and in Arizona on Thursday. Yet Mr. Trump’s positive test has plainly injected an extraordinary measure of uncertainty into the race.
For the first six months of the pandemic, the US lagged behind dozens of other countries in rolling out apps to alert citizens when they’ve come in contact with someone who has tested positive for Covid-19. But states are finally rolling out a wave of apps based on open-source software that has made their proliferation faster and cheaper.
Now people just need to download them.
The most recent additions to the canon are New York and New Jersey, which each launched apps on Oct. 1. By the next day, iPhone and Android users had installed the New York app about 250,000 times.
Since August, seven other US states and Guam have launched exposure notification apps. Four of
New York and New Jersey on Thursday announced the launch of new COVID-19 apps based on the Apple and Google Exposure Notification framework.
New York Gov. Andrew M. Cuomo and New Jersey Gov. Phil Murphy made the announcement on Thursday. In a press release, Gov. Cuomo’s office also noted that the apps are interoperable with similar exposure notification titles recently released in Pennsylvania and Delaware, meaning the apps provide patchwork coverage across state lines.
With integrated apps, New York, New Jersey, Pennsylvania and Delaware were able to create a regional COVID Alert network similar to one in development on the West Coast. The state of Connecticut has also announced that it will launch a similar exposure notification system “in the coming weeks.”
“Testing is to identify a person, so you can isolate and quarantine that person and then find the connections from that person, and that’s contact tracing. We have
Ventilation systems in many modern office buildings, which are designed to keep temperatures comfortable and increase energy efficiency, may increase the risk of exposure to the coronavirus, particularly during the coming winter, according to research published in the Journal of Fluid Mechanics.
A team from the University of Cambridge found that widely-used ‘mixing ventilation’ systems, which are designed to keep conditions uniform in all parts of the room, disperse airborne contaminants evenly throughout the space. These contaminants may include droplets and aerosols, potentially containing viruses.
The research has highlighted the importance of good ventilation and mask-wearing in keeping the contaminant concentration to a minimum level and hence mitigating the risk of transmission of SARS-CoV-2, the virus that causes COVID-19.
The evidence increasingly indicates that the virus is spread primarily through larger droplets and smaller aerosols, which are expelled when we cough, sneeze, laugh, talk or breathe. In addition, the
Back in April, Apple announced that it was partnering with Google build a technology framework to help governments and health agencies reduce the spread of the virus, with user privacy and security central to the design. I got COVID-19, and here’s how it worked.

Apple’s speed in deploying an entirely new layer of technology for securely tracking COVID-19 exposure notifications — just weeks after the pandemic burst onto the world stage — is easier to understand when you realize it wasn’t entirely new technology.
Like the aluminum in its iPads and iMacs, the privacy-centric Bluetooth key sharing mechanism Apple developed to track COVID-19 exposures had a former life. Last summer at WWDC19, Apple’s software chief Craig Federighi outlined a suspiciously similar approach to tracking “exposures,” albeit rather than tracing pandemic spread, the technology had been applied to finding lost hardware.
Over the past two years, a key driver of top performance for mutual funds was how big their exposure was to the big technology and Internet companies such as Microsoft (MSFT) and Apple (AAPL).
As these technology and communications stocks rallied, many funds rode the rising tide higher, leading to organically higher portfolio positions in these sectors. The average U.S. stock-fund allocation to the communication services and information technology sectors rose to 28.6% at the end of August 2020 from 24.7% in October 2018. More specifically, funds ended up holding much larger positions in software, semiconductor, and IT service stocks.
But some funds went even further, increasing their exposure well above the market indexes against which funds measure their portfolio weightings and performance—in some cases, adding another 10% of their portfolio to these stocks beyond the increase in the index holdings.
