Paul Ryan makes 'good bet' on US oil and gas, domestic producer backs SPAC deal
Love is in the air for Halsey and Alev Aydin ! The couple showed their love in PDA-filled moments while out and about in Los Angeles on Thursday (October 27).
The 28-year-old singer and his 39-year-old beau looked relaxed as they headed for lunch at the Thirteen Mexican Grill. The "Nightmare" singer wore a white tank top with light-colored pants and rubber boots for her day. The producer chose a white shirt and black pants and boots. They were holding hands and Halsey was joking as she grabbed an Aleve as they went to eat with smiles on their faces.
News of their romance broke in January 2021, when Halsey announced on Instagram that she was pregnant with her and Alev's son, Ender. born in july
They wrote the ad as "terrible" at the time. Alev commented on the post, “My heart is so full I love you Madhuri.”
Although they have known each other for years, it took them a while to move on from friendship to something else.
" Alev and I have been good friends for about four years," Halsey told Allure in August 2021. "And when the stars aligned, our relationship became romantic, and we were both like, 'Oh my God!” You are the one I should start a family with.” There were a lot of comments about this.
Both parents shared photos of their baby on Instagram. However, they keep their relationship out of the public eye.
"Nobody knew I was dating anyone other than me," the singer said in the same interview. '…I signed up to give my whole life, but not the people I love.
But that didn't lessen things between him and Aleven.
"One of the reasons it took Alev and me so long to get to this point was because I loved him so much," she recalled. "He was writing a movie about my life, a biography, so we spent a lot of time together. One night we went to a busy place together. When we went there, we were hit by paparazzi and a lot of fans and people. Signing records and stuff like that. I wanted to. It was like a scene from a movie. It was amazing. I looked over my shoulder as the crowd pushed me and I I said, "Oh my God, I didn't say goodbye!"
Halsey was worried, but her counterpart reminded her that it was "no big deal". It looks like a perfect combination!

Elizabeth Hurley rose to fame in 1994 thanks to her cute and bushy dresses, and since then she hasn't stopped taking fashion risks.
Not very famous, the British beauty is famous for being the model girlfriend of the actor Hugh Grant , she was a fashion girl in one night thanks to a black Versace dress with a large gold chain on the side. . It is used in four wedding and funeral ceremonies . Suddenly everyone wanted to know who this beautiful woman with an unusual figure was.
She soon became the face of Estee Lauder, overseeing fragrances such as Sensus, Intuition and Pleasures, as well as the brand's cosmetics. Now a sales model, Elizabeth is building on the acting career she began in the late 1980s.
In 1997, Liz co-starred with comedian Mike Myers in the film Austin Powers: International Man of Mystery , making her a Hollywood superstar in her own right. In 1999, she reprized her role as Vanessa Kensington in Austin Powers: The Spy Who Got Me .
As Liz began her modeling and acting career, she and Hugh split amicably in 2000 after 13 years together. They remain best friends.
"I still see him for screenwriting advice, even though I'm very happy, I have five kids, and I'm very satisfied with my life, there are still parts of us that we support," she told People in October 2021. , "And he's still the person I go to for career advice." The star has a son, Damian, born in April 2002, who she shared with the late producer Steve Bing.
Since then, Liz has appeared on The CW's Gossip Girl and E!' s she starred in Royals, showing off her stunning outfits in both roles . In real life, she is a style superstar as evidenced by her previous Versace dresses. Since then, the brunette beauty has stuck to red carpet glamor to show off her stunning, often bold and toned body.
"In the '90s, I was very confident because I was young and early in my career, but now that I have more experience and knowledge, I think I'm more comfortable with myself. I've learned a lot through the years of practice," Liz explained of her sense of style in a 2022 interview with karenmillen.com.

Nobody wears a high waisted bikini like Taylor Swift ! The singer rarely presents her outfit in a bathing suit, but when she does, fans take notice.
Throughout her time in the spotlight, the "Look What You Made Me Do" singer has been panting over her body image. However, growing up in the public eye, he spoke openly about overcoming challenges.
"I didn't know if I would be comfortable talking about my body image and how unhealthy it was for me — my relationship with food and everything else over the years," Taylor said in January 2022, referring to her. . "But the way Lana [Wilson , director of the film] tells the story really makes sense. I'm not as clear on this as I should be because there are a lot of people who could better talk about it. But all I know is mine. The experience. And my relationship with food was the same science The breath I applied to the rest of my life: If I got hit in the head, I liked it. If I got a penalty, I felt it was bad.
Over the years, the singer has also shared some quotes about maturity with her fans. On Elle 's March 2019 cover, Taylor revealed some of the things she learned before she turned 30.
“Social media can be great, but it can fill your mind with images of who you are not, how you fail, or who is ever in a cooler place than you,” the Midnight musicians told TIME. "One of the things I do to reduce the odd laser beam of danger is to turn off comments. Yes, I don't leave comments on my posts. This is how I show my friends and fans my life updates, but I train my brain not to have to confirm when someone tells me I'm watching 🔥🔥 🔥".
Having said that, I asked readers to remember having fun, especially when it comes to clothing.
“Fashion is all about fun experiments,” Taylor said, referring to the age of hair lightening. “If you don’t look at pictures of your old self and despise, you are doing something wrong. Watch: Blechilla.”

The breach of Red Bull's budget limit has been one of F1's main talking points in recent weeks, with the FIA insisting on keeping the details of Red Bull's fine secret.
See the original article for embedded media.
Following an FIA analysis (which concluded that Red Bull was overreacting in 2021), Red Bull issued a statement strongly rejecting the idea that it had exceeded its budget limit.
The Austrian national team also hinted that legal action could be taken, and insisted that the team is ready to explore all available options.
However, Red Bull eventually admitted that they exceeded last season's budget cap and agreed to a $7 million fine for next season and a 10% reduction in time spent in the wind tunnel.
As the 2022 champions, Red Bull will have less time in the wind tunnel than any other F1 team, and an FIA penalty will make that shortfall even worse.
The FIA confirmed that Red Bull's total financial excess of the budget limit was $2.2 million. It should be noted that there are inconsistencies in the application of taxes.
If taxes were properly implemented, Red Bull's budget surplus would be $0.5 million.
The tacit agreement between the FIA and Red Bull states:
Red Bull Racing was found to be ineligible. However, the Fee Limit Administration has accepted the following:
"Red Bull Racing has cooperated during the review.
"He has tried to provide additional information and evidence in a timely manner when requested.
“[And] that this is the first year of full implementation of the Financial Regulations.
"There are no allegations or evidence that Red Bull Racing at any time attempted to act dishonestly, dishonestly or fraudulently and did not knowingly withhold any information from Cost Cap management."
This penalty sets a precedent for how teams will be punished for exceeding budget limits in the future and will help determine the extent to which F1 teams will meet these limits.
The FIA has confirmed that Red Bull have been sanctioned both sportingly and financially, but it remains to be seen how useful these sanctions will become.
The $7 million fine is insignificant for a financial powerhouse like Red Bull, so the question now is how much wind tunnel time reduction will affect the team in 2023.
NEW FIA decision on Red Bull foul. And Hamilton made a big request.
In Dinesh D'Souza's underrated and underrated quasi-documentary 2000 Mules , he accuses some American voters of acting like "donkeys," rigging fake ballots to influence the outcome of the 2020 presidential election.
These so-called messengers play a key role in the film, which uses surveillance footage of him putting ballot papers in the mailbox and allegedly arresting him for his crimes. As D'Souza's voiceover says, "What you see is evil. These are fake voices."
The only problem, of course, is that according to a voter who is considered a mule, they are all fake. Mark Andrews sued D'Souza on Wednesday, alleging that D'Souza and his associates falsely accused him of voter fraud by including "snippets of unsolicited pseudoscience and innocent voter surveillance videos" in the May 2022 documentary.
The 2,000 mules show that a fugitive Andrews dropped five ballots into Georgia mailboxes in 2020, according to his federal complaint. "In fact, the video clip shows Mr. Andrews legally voting for himself and his family, a method of voting expressly permitted by Georgia law," he said.
An investigation by the Georgia Bureau of Investigation found Andrews innocent of wrongdoing and dismissed a complaint filed against him after the May documentary.
The lawsuit explains that: "The defendants knew at all times that their version of Mr. Andrews was a lie, as well as the entire 2,000 mule account." But they continue to spread lies to enrich themselves. At the time the lawsuit was filed, the defendants' social media accounts and websites continued to promote the film, using Mr. Andrews as an example of a criminal "ass."
Later, in the 123-page complaint, "the defendant promoted the film and novel 'The Donkey' on television, radio, the Internet and other media, including to millions of viewers on Fox News, and has repeatedly shared Mr. Andrews as a role model."
The defendants in the lawsuit are Greg Phillips and Katherine Engelbrecht D'Souza of the controversial and conservative organization True the Vote. In September, Konnech, an election logistics software company, sued the group, accusing Phillips and Engelbrecht of stealing data and waging a xenophobic "dirty campaign" against its CEO.
"The organization believes that the allegations against True The Vote in this case will be proven without merit," a spokesperson for True The Vote told the Atlanta Journal-Constitution.
Andrews is seeking an unspecified amount in her lawsuit for defamation, intimidation and invasion of privacy. "As a black person who grew up in the American South before the Voting Rights Act was passed, Mr. Andrews values the right to vote, has always been proud to vote, and has worked tirelessly to instill those values in his family."
"Now, because of the defendants' plot to discredit and intimidate Mr. Andrews, he will not be able to vote again without looking back."

And when people watch the show, my face moves in a way that distracts me. I'm with these beautiful women who look flawless, and I don't do things like that.
The following year, the former Bond girl admitted that she had tried Botox, but it wasn't. "I don't like how my face feels afterwards, but it definitely feels more comfortable. It makes me feel like someone is pressing my forehead or something," Dennis told Us Weeklyin 2020 .
Bravo fans noticed that the horror movie 3 star had a goiter during the 2019 RHOBH meeting . After the measurements were taken and examined by a doctor, Denise thanked fans for bringing the medical problem to their attention.
"It's amazing to me how my thyroid has changed in such a short time and eliminating gluten from my diet. Some of you commented after #RHOBH that my thyroid has increased in size," she wrote on Instagram. Think about how much our diet affects our bodies and how toxic gluten is to me… Thanks to everyone who messaged me.
Denise has been open about the effects of her thyroid on her body, especially when critics accused her of having plastic surgery on her face.
She continued to Us Weekly, "I had a thyroid problem last year. " "So I gained a little weight and people thought I had a lot of fillers on my face. I don't think so, that's called weight gain."

As gravel biking grows in popularity around the world, the former Midwestern foot sport has found a home in southern Arizona.
Gravel cycling, also known as gravel or simply gravel, has become popular in recent years, primarily off-road riding on mostly dirt and gravel roads.
Start the day smart. Get all the news you need in your inbox every morning.
People say they like the sport because it has aspects of road cycling and mountain biking.
Professional cyclist Sarah Swallow lives a semi-nomadic lifestyle in Patagonia for part of the year. Organize the Ruta del Jefe race, a competition that aims to raise awareness of the area's complexity and unique culture.
"The event honors the ancestral lands of the Tohono Odham, Yomi and Chirikawa Apaches," Ruta del Jefe said on its website. 16% withdrawal, 16% profit will be indivisible Tohono.
Dirt roads travel all over the world, but keep coming back to southern Arizona for its unique and diverse landscape. Located in southeastern Arizona and northern New Mexico, the Sky Islands Mountains are one of the most diverse regions on the planet.
Southern Arizona "lies near the Sonoran and Chihuahua deserts as well as the western Sierra Madre," he said. Considered the Sky Islands, the Santa Catalina Mountains are a popular spot for gravel riding.
For long-distance cyclists, this means quick transitions from cactus and desert scrub to foot-high grasslands with oaks and cedars and streams and even ponderosa pine forests.
And as gravel biking becomes more common, people are discovering the magic of Arizona's southern landscape.
Areas such as Patagonia, Elgin, Sonoita, the Santa Rita Mountains, the Chirikawa Mountains, and the Catalina Mountains are popular destinations.
Swallow noted that southern Arizona is experiencing a cycling boom in the wake of the Covid-19 outbreak.
Because places like Patagonia are among the few places with dry dirt roads in the winter, "people flock to the area," says Swallow, who says that through his work he tries to develop a special respect and understanding of "the area." ” and fragile of “complex problems”.
Gravel cycling has been around for a long time, but has gained popularity in recent years.
Mark Stephens told the Arizona Republic that what started as a "crazy idea" of two Midwesterners to ride their bikes on dirt roads in Iowa, has turned into a booming industry.
"People are looking for safe, quiet places. Gravel paths provide that," says Stevenson, who helped found the modern gravel bike scene. He is one of seven gravel racers, the first, to be inducted into the 2022 class of the Gravel Hall of Fame.
With its road and mountain bike features and accessibility for everyday and adventure cyclists, dirt biking is a competitive sport, says Tucson cyclist and athlete Paige Redman.
Redman is a two-time champion of the Long Voyage 300 women's division, a gravel endurance race in Lincoln, Redman, Nebraska.
“There is something adventurous about gravel. Every time you hit the ground running, it feels like an adventure, even if you've done it before,” Redman said.
While gravel biking across the country is fun, Arizona's desert landscape and diverse wildlife make gravel biking even more adventurous.
While driving in the Midwest, he may see deer and rabbits, but in Arizona he sees a variety of animals such as baboons, hawks and snakes.
Redman has compiled a long list of biking spots, including the Arizona Trail in the south to Giant's Cave, as well as places as far north as the Phoenix Canal, Chino Valley and Prescott County.
Redman not only fell in love with the sport, but also with a family of gravel riders; Competitive as a road cyclist and relaxed as a mountain biker, he says.
"Includes gravel," said Redman.
Gravel begins
The gravel bike dates back to the 1800s, when the bicycle was invented. Everyone rides gravel bikes where there are no paved roads. When paved roads appeared, cycling focused on riding on sidewalks because it was easier and safer, Stevenson said.
this year
In 2004, when Stevenson, who had a mountain bike background, was working at the ski shop with Iowa Bike and Endurance Mountain Bike partner Jeff Kerko, they came up with an idea.
Inspired by their boss who decided to ride a road bike in Iowa the day before, they thought the challenge could be tackled off-road with a mountain bike.
They have an off-road race in the state called Trans Iowa. The first Trans Iowa event was held in April 2005 and was 310 miles long and had to be completed in 35 hours or less.
"To our knowledge, this has never been done before," he said.
Thanks to Kerkov's contacts in the industry, many endurance athletes attended the event and many were unable to complete the event, which meant Stevenson and Kerkov had something to do.
People brought all kinds of bikes to the competition: from old Schwinn cruisers to hybrids and mountain bikes.
"Bring whatever you have, whatever you think you can," Stevenson said.
They quickly learned that this phenomenon was not limited to mountain biking.
Inspired by the event, many cyclists want to build their own off-roaders. Stevenson said that among other things he co-founded Unbound Gravel, the first gravel event in the United States.
And while there are gravel-specific bikes with thin frames and fat tires like road bikes, he says many bikes can be used for gravel riding.
Fast forward to 2022 and gravel races across the country like the SBT GRVL in Colorado, the Belgian Waffle Ride across the country and the Lifetime Grand Prix Series among other interstate races.
"It all started with us," said the director, noting that in the past off-road racing was aimed at mountain bikers.
When companies started making dirt bikes in 2012, the sport became more popular, Stevenson said.
Keep a calendar of events for all races.
He knew how many opportunities "I can count on my hands" in 2018. During the year he said there were "over 700 events" in 2020, not including team races.
Unlimited Gravel in Kansas has grown from 34 participants in 2006 to nearly 4,000 in 2022.
Gravel bikes are a top seller. According to the 2021 market survey, gravel bike sales are up 109 percent from two years ago.
Both Redman and Swallow agree that while recreational gravel biking is popular in Arizona, gravel racing, which draws people from all over the country, has lagged behind other states.
Because the permit is so expensive and difficult to obtain, it's "a major barrier to very small, low-impact gravel events," Swallow said.
He noted that getting a permit from the Arizona Department of Transportation is especially difficult because the main dirt road connections in southern Arizona are Highway 82 and Highway 83.
For recreational cyclists, Arizona continues to be a popular destination for off-road exploration, and gravel biking is the way of the future, according to Sitcernak.

We discuss an incredible interview with Hilary Metz of Cassava Science |: Small Cap Equity Investing
Quantum computers have recently attracted a lot of attention for their ability to solve problems in a matter of hours, where the best supercomputers can estimate the age of the universe (i.e., tens of billions of years). Their real-life applications are diverse and range from drug and materials development to solving complex optimization problems. Therefore, it is mainly focused on scientific and industrial research.
Traditionally, a "quantum advantage" is required in terms of raw computing power: we want to compute (significantly) faster.
However, today's power consumption issues may also require investigation, as today's supercomputers sometimes consume as much electricity as small cities (which may actually limit the growth of their computing power). By 2020, information technology will account for 11% of global electricity consumption.
Why care about the energy consumption of a quantum computer?
Since a quantum computer can solve problems in a few hours that would take a supercomputer tens of billions of years to solve, we naturally expect it to consume less energy. However, building such a powerful quantum computer will require solving many scientific and technological challenges, perhaps a decade or more of research.
A simpler goal is to create a less powerful quantum computer that can perform calculations at the same time as a supercomputer but consumes less energy.
These potential energy advantages of quantum computing have already been discussed. Google's Sycamore quantum processor consumes 26 kilowatts of electricity, far less than a supercomputer, and runs quantum testing algorithms in seconds. After the experiment, scientists proposed a classical algorithm to simulate the quantum algorithm. The first proposal of the classical algorithm required more power, demonstrating the energy advantages of quantum computing, but other more energy-efficient proposals soon followed.
Therefore, the question of power benefits is still open and an open topic for research, especially since Sycamore's quantum algorithm has yet to identify a "useful" application.
Superposition: A Fragile Phenomenon of Quantum Computing
To find out whether a quantum computer provides an energy advantage, we need to understand the basic laws by which it works.
Quantum computers manipulate physical systems called qubits to perform calculations. A qubit can take two values: 0 ("ground state", for minimum energy) and 1 ("excited state", for maximum energy). It can also hold a "superposition" of 0's and 1's. How we interpret superposition is still a hot topic of philosophical debate, but in simple terms it means that a qubit "can be both in the 0 state and at will 1 with some" "probability amplitude".
With this possibility, we can greatly simplify the working principles of a quantum computer by saying that it implements an algorithm that performs arithmetic operations "at once" on many numbers (in this case, 0 and 1 at the same time). This advantage becomes apparent as the number of bits increases: 300 stacked qubits can simultaneously represent 2 to the power of 300. For example, this is roughly the number of atoms in the observable universe, so it remains simple to map multiple states simultaneously on a supercomputer. unreal.
However, the fundamentals of quantum theory tell us that if the amplitude value of this probability were "measured" by another physical system, the superposition would be destroyed: the qubits would shrink to a value of 1 or 0, causing an error in the calculation.
A striking example of such annihilation is the absorption of a photon (a light particle with a small energy packet) by a qubit. If it does, it's because it's not in its maximum energy state (where it can absorb energy, the energy of photons). Thus, the photon and through it the "neighborhood" of the qubit indirectly "finds" the value of the amplitude, destroying the superposition. This is called decoherence.
In general, the challenge is to make sure that the qubits are sufficiently isolated to prevent information loss: we cannot allow photons or other particles to interfere with our qubits. This is difficult because even qubits must be controlled: they cannot be completely isolated.
This lack of protection is a major source of error in qubit-based calculations. For example, one of the more mature qubit technologies experiences an error every 1000 operations. If you consider that a typical quantum algorithm takes 10¹³ operations, you can see that there are a lot of them.
Maintaining obstacles requires energy
The computing power costs of quantum computers will primarily be driven by the need to "protect quantum data". For example, to avoid the above problem, the qubit environment must be set close to absolute zero (-273 °C) to ensure that the environment is not filled with photons. This is a process that requires energy.
Some other technologies, such as quantum error correction, also store quantum information and can improve operational accuracy. However, apart from the problems they cause, these technologies also lead to very high energy costs, as additional error detection algorithms or error detection qubits etc. are required.
In short, the more precisely we want to perform operations on a qubit, the more we protect it and the more energy we have to spend on it. In quantum computing, there is a very strong relationship between "error rate" and "energy". Therefore, understanding these correlations may enable the development of energy-efficient computers.
Is it possible to obtain quantum energy?
Some theoretical studies have been able to estimate the energy costs of building quantum computers, but in non-optimized systems, often using simplified computer models without exploiting the correlation between error rate and energy in particular.
Exploiting this correlation can lead to powerful optimizations that reduce the energy consumption of the algorithm. In practice, this requires an interdisciplinary approach that includes understanding the fundamental phenomena that cause decoherence, modeling quantum error correction algorithms and codes, and all the "engineering" required to control qubits. Thus, it is possible to calculate the minimum energy costs required to solve various problems, focusing on the error probability of the algorithm considered "acceptable".
As we can see, for qubits of excellent quality (that is, qualities that are practically unattainable today), there are tasks for which a quantum computer can use a hundred times less energy for the computation time than the best modern supercomputers (in a comparative sense, both can complete the task in a reasonable time will know). This power factor of 100 is also an indicator: more energy savings can be imagined with more improvements.
This is because quantum computers perform calculations using fundamentally different processes from quantum computers: one deals with qubits and the other deals with qubits. Therefore, the number of transactions for the same activity and even with the same processing time can be drastically different. Furthermore, the processes performed on a quantum computer will involve fundamentally different physical processes than those performed on a supercomputer. Taken together, these two observations show that, conceptually, even with the same computation time, a quantum logic process consumes more energy than a conventional logic process, but fewer quantum logic operations could mean that a quantum computer would ultimately be more powerful. effective.
Of course, this example sometimes comes from theoretical calculations based on very optimistic assumptions. However, this suggests that one of the main advantages of quantum computing may be active before computation.
