Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
Texas A&M University researchers have developed analytical tools that can help characterize the movements of floating but anchored wave-energy devices. Unlike complicated simulations that are expensive and time-consuming, they said their technique is fast, yet accurate enough to estimate if wave-energy devices will turn over in an ever-changing ocean environment.
“Wave-energy converters need to take advantage of large wave motions to make electricity. But when a big storm comes, you don’t want big wave, wind and current motions to destroy these devices,” said Dr. Jeffrey Falzarano, professor in the Department of Ocean Engineering. “We have developed much simpler analytical tools to judge the performance of these devices in a dynamic ocean environment without necessitating massive amounts of simulations
Jeff Gundlach, the billionaire investor known as the “Bond King,” predicted in a RealVision interview published on Friday that stocks would crash in less than 18 months.
The DoubleLine Capital CEO also said the US dollar would dive in the long run, argued that tech stocks like Apple and Amazon were the only US equities worth owning, and questioned bitcoin, welfare, and Chipotle’s valuation.
Here are Gundlach’s 10 best quotes from the discussion.

In July heavy rains triggered landslides and floods in Nepal that ultimately killed more than 130 people. As soon as the rain started falling, BYU professor Jim Nelson knew things could get bad.
That’s because the water-modeling software created by Nelson and colleagues from NASA under the Group on Earth Observations Global Water Sustainability (GEOGloWS) Partnership can predict the rise and fall of every river on the face of the planet. And in the case of Nepal, the streamflow forecasts were warning of severe flooding throughout the country.
Fortunately, the predictive models, accessible through the BYU software, made it into the hands of emergency agencies in Nepal, saving many lives in what could have been a catastrophic loss of life.

Expanding routine newborn screening to include a metabolic vulnerability profile could lead to earlier detection of life-threatening complications in babies born preterm, according to a study by UC San Francisco researchers. The new method, which was developed at UCSF, offers valuable and time-sensitive insights into which infants are at greatest risk during their most vulnerable time, immediately after birth.
The study, published in Nature Pediatric Research by scientists at the UCSF California Preterm Birth Initiative (PTBI-CA), assessed the records of 9,639 preterm infants who experienced mortality or at least one complication or mortality.
Using the results of standard newborn profiles and blood tests, they identified a combination of six newborn characteristics and 19 metabolites that, together, created a vulnerability profile that reliably identified preterm babies at substantially increased risk for death and severe illness.
“Our results point to a number of potential biological pathways that may play a key role
Blockstream CEO Adam Back believes Bitcoin’s market cap will increase by 400% within two years
This is in response to another forecast which said Bitcoin will hit that mark by 2025
At the moment, Bitcoin is marred by lower volatility
Famed cryptographer and Blockstream CEO Adam Back believes Bitcoin can easily hit a market cap of $1 trillion by 2022, three years earlier than the estimate from investment company Ark.
Ark made news in the past because of its aggressive price prediction for Tesla. Back said Ark’s forecast that Bitcoin would hit a $1 trillion market cap by 2025 was very conservative. “I’d say Bitcoin likely sees a $1 trillion market cap within 2 years, probably sooner,” he said on Twitter.
Back’s message was a response to Yassine Elmandjra, an analyst from Ark Investment Management. Last month, Elmandjra said Bitcoin was in its path to monetization, with substantial
Billboard Japan and NTT Data/NTT Data Institute of Management Consulting (NTT Data/IMC) partnered on a new project that combines the former’s chart data and the latter’s neuroscientific technology to develop a new way to analyze music trends.
Billboard Japan’s Hot 100 song chart is based on a weighted formula incorporating eight metrics such as CD sales, downloads, streams and Twitter mentions. NTT Data/IMC is a pioneer in the advancement of the brain information business, in part through its development of the “NeuroAI” that predicts the cerebral activity and perceptual content of people viewing moving images. The underlying technology of NeuroAI was adopted by this year’s AAAI Conference on Artificial Intelligence (AAAI-20).
The collaborative project used technology called “NeuroAI-Music” that simulates the cerebral activity of people listening to music. NeuroAI-Music succeeded in estimating and characterizing the cerebral activity per second of music from audio signals, making it possible to quantitatively extract
Tim Cook, Apple’s CEO, said that the success of remote working during the pandemic meant the tech giant would not “return to the way we were.”
Some aspects of virtual working were here to stay, he said, without being specific.
But Cook also stressed the limitations of remote working, such as not having impromptu meetings with colleagues. He cannot wait to return to the office, he said.
He hoped most employees would be back in the office by the end of 2020, he added.

Apple CEO Tim Cook said Monday that some of the tech giant’s new working-from-home habits were here to stay.
During the pandemic, the company has found “there are some things that actually work really well virtually,” he said in an interview at The Atlantic Festival. It meant Apple would not “return to the way we were.”
The first Apple device to feature a Mini-LED display will be a new iPad Pro, Apple analyst Ming-Chi Kuo has predicted in a new research note seen by MacRumors and AppleInsider. Kuo reports that Mini-LED display components will be mass-produced in the fourth quarter of this year, though it’s unclear when the new iPad Pro could actually release. Last year, Kuo predicted a third-quarter 2020 launch for the new iPad Pro with improved display technology. Apple last updated its iPad Pro lineup back in March.
Apple has long been rumored to be developing six devices with the new display technology, which offers similar benefits to OLED — like localized dimming for deeper blacks and higher contrast — without the downside of burn-in. It does this by using an array of thousands of tiny LEDs as a backlight, which can be turned on and off individually to offer a sharper
All animals great and small live every day in an uncertain world. Whether you are a human being or an insect, you rely on your senses to help you navigate and survive in your world. But what drives this essential sensing?
Unsurprisingly, animals move their sensory organs, such as eyes, ears and noses, while they are searching. Picture a cat swiveling its ears to capture important sounds without needing to move its body. But the precise position and orientation these sense organs take over time during behavior is not intuitive, and current theories do not predict these positions and orientations well.
Now a Northwestern University research team has developed a new theory that can predict the movement of an animal’s sensory organs while searching for something vital to its life.
The researchers applied the theory to four different species which involved three different senses (including vision and smell) and found
