## MATHEMATICS • MAY 24, 2021

# *Noise is commonly discarded, but identifying patterns in noise can be very useful.*

*Generalize the Hearst exponent by adding more coefficients in order to get a more complete description of the changing data. This makes it possible to find patterns in the data that are usually considered noise and were previously impossible to analyze.*

*The development of this mathematical apparatus can solve the issue of parameterisation and analysis of processes for which there is no exact mathematical description. This opens up enormous prospects in describing, analyzing and forecasting complex systems.*

One of the metrics used in economics and natural sciences in time series analysis is the Hurst exponent. It suggests whether the trend present in the data will persist: for example, whether values will continue to increase, or whether growth will turn to decline. This assumption holds for many natural processes and is explained by the inertia of natural systems. For example, lake level change, which is consistent with predictions derived from analysis of the Hurst exponent value, is determined not only by the current amount of water, but also by evaporation rates, precipitation, snowmelt, etc. All of the above is a time-consuming process.

A new topic a new challenge for future civilizations.

I won’t write an introduction I will ask couple of questions to make you think about it.

In the forth industrial revolution are we going to change the way we reproduce? Could be the first step for post-human era in 2040?

How can we change the way we deal with economics? Because economy depends on population grow. In a way or another world population will stop at 11 billion so it is necessary to change the economy.

How can we colonize and expand while fertility rate is going down could another creatures like machines and biological engineered animals help us to expand and the human specie will limit its population?

Dr. Thomas Lovejoy, is an innovative conservation biologist, who is Founder and President of the non-profit Amazon Biodiversity Center, the renowned Biological Dynamics of Forest Fragments Project, and the person who coined the term “biological diversity”.

Dr. Lovejoy currently serves as Professor in the department of Environmental Science and Policy at George Mason University, and as a senior fellow at the United Nations Foundation based in Washington, DC.

Dr. Lovejoy has also served as the World Bank’s chief biodiversity advisor and the lead specialist for environment for Latin America and the Caribbean, the first Biodiversity Chair of the H. John Heinz III Center for Science, Economics and the Environment, President of the Heinz Center, and chair of the Scientific Technical Advisory Panel (STAP) for the Global Environment Facility (GEF), the multibillion-dollar funding mechanism for developing countries in support of their obligations under international environmental conventions.

Spanning the political spectrum, Dr. Lovejoy has served on science and environmental councils under the Reagan, Bush, and Clinton administrations. At the core of these many influential positions are seminal ideas, which have formed and strengthened the field of conservation biology.

In the 1980s, Dr. Lovejoy brought international attention to the world’s tropical rainforests, and in particular, the Brazilian Amazon, where he has worked since 1965.

With multiple co-edited books (including Biodiversity and Climate Change: Transforming the Biosphere; Drones for Conservation — Field Guide for Photographers, Researchers, Conservationists and Archaeologists; Costa Rican Ecosystems; Climate Change and Biodiversity; On the Edge: The State and Fate of the World’s Tropical Rainforests), Dr. Lovejoy is credited as a founder of the field of climate change biology. He also founded the series Nature, the popular long-term series on public television.

Here’s what we already know about Ford’s electric F-150.

Ford is set to unveil its next major electric vehicle, the F-150 Lightning, at 9:30PM ET on Wednesday, May 19th. But this isn’t just another EV event. An electric version of the automaker’s iconic F-series pickup truck is a very big deal for Ford, for the auto world, for car buyers, and even for the US economy.

Ford is very proud of its F-series trucks, and for good reason. It’s the bestselling truck in the US for 44 years. It’s also the bestselling vehicle in the country, period. According to Edmunds, F-series trucks are the most popular vehicle in 30 out of 50 states in the US.

That means the F-Series trucks is central to Ford’s profitability. The Detroit automaker raked in around $42 billion in revenue in 2019 from nearly 900000 F-series truck sales in the US, according to a Boston Consulting Group study commissioned by Ford — more than most major companies and about four times as much as Tesla made in all of 2020.

Cryptocurrencies like Bitcoin have been billed as a major disruptor to finance. But digital currencies issued by governments might be even more radical—they may even threaten the future of traditional banking.

Local media reports quoted Wang as saying that artificial intelligence, 6G, quantum technology, driverless vehicles, intelligent networks and other “frontier areas” would be the focus of Shenzhen’s investment plans, while the value of its digital economy would account for more than 31 per cent of GDP by 2025.

Money will be used to support innovation in core technologies, city’s Communist Party chief Wang Weizhong says.

Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.

But a key step in that process, known as the or OER, has proven to be a bottleneck. Today it’s only about 75% efficient, and the precious metal catalysts used to accelerate the reaction, like platinum and iridium, are rare and expensive.

Now an international team led by scientists at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory has developed a suite of advanced tools to break through this bottleneck and improve other energy-related processes, such as finding ways to make lithium-ion batteries charge faster. The research team described their work in Nature today.

And as well as producing less waste, insects can also live off food and biomass that would otherwise be thrown away, says Collins, contributing to the circular economy, where resources are recycled and reused. Insects can be fed agricultural waste, such as the stems and stalks from plants that people don’t eat, or scraps of food waste. To complete the recycling chain, their excrement can be used as fertiliser for crops.

Insects are a nutrition-dense source of protein embraced by much of the world. Why are some of us so squeamish about eating them?

Coal is a highly polluting and expensive way to generate electricity. This analysis shows that we have economic alternatives to continuing to burn coal for power in the US. Furthermore, analyses such as “The 2035 Report” show that we can fully retire coal, stop building other fossil fuel plants (namely gas), and still reliably meet electricity demand, while providing a host of environmental and societal benefits. There are existing policies that can help policymakers closely examine the cost burden of generation resources used today, procure cheaper and cleaner generation resources going forward, and address current assets on the books. The continuation and intensification of the coal cost crossover demands attention from policymakers and consumers alike.

The costs of most existing US coal-fired power plants are now more expensive than the total costs of wind and solar.

The mood a year later is very different, despite a brutal surge in coronavirus cases that is threatening the economic recovery. India’s startup community has found itself in an unprecedented funding bonanza.

In the first four months of 2021, 11 startups have attained unicorn status, meaning they’ve reached a valuation of at least $1 billion.
