Beijing: At least seven people were killed and two others remained missing after a ship sank off the coast of China’s Shandong Province, local maritime rescue authorities said on Saturday. The accident happened around 5:55 p.m. on Friday, when the ship from the north Hebei Province rocked by gale and sank near the port of the city of Rizhao. So far seven victims were found, and the rescue team are still searching for the missing ones, state-run Xinhua news agency reported. The wind speed was up to 50 meters per second on the water when the accident happened, authorities said.

As many as 17 percent of those polled said that they wouldn’t consider buying another truck, citing fuel economy and cost of maintenance as the primary factors for leaving the segment. Of those that have already dumped their trucks, 35 percent switched to a sedan and, surprisingly, only 37 percent moved to an SUV or crossover. This goes against the broader market trends we’re seeing, where SUVs are crushing sedan sales.What we’d be curious to see is how these types of sentiments found by CarGurus translate across different kinds of trucks. For example, does a midsize truck owner care more about their brand than a full-size truck owner? Or is the person who buys an F-150 more of a tech evangelist than the person who drives a Ram 3500 HD?We’ll have to wait until next year to find out.

Emme Hall/Roadshow Truck buyers are an interesting group of people. Among them, you’ll traditionally find some of the most brand-loyal consumers in the automotive space as well as some of the most price-conscious. The truck segment is also interesting because of how quickly it’s changing. What were once utilitarian penalty boxes on wheels are now rivaling some of the world’s most popular luxury cars when it comes to opulence. To help make sense of what’s going on in the world of trucks, CarGurus.com has again conducted a survey of truck owners. This time around, CarGurus expanded its sample size significantly to more than a thousand current and former truck owners. What were the takeaways?To start with, the upward march of truck prices is beginning to undermine some of that fierce brand tribalism that we’ve traditionally associated with truck buyers. CarGurus found that 67 percent of buyers think trucks are too expensive in 2019, with more than 80 percent of survey participants over the age of 45 agreeing with that. 68 Photos Go west, young trucker, in the 2019 Ram 1500 Post a comment Tags 2020 Hyundai Palisade review: Posh enough to make Genesis jealous 2020 Kia Telluride review: Kia’s new SUV has big style and bigger value 0 The 2020 Chevy Silverado HD gets a new look to match its capability Around 54 percent of those surveyed said that price would cause them to consider switching brands, with 70 percent saying that they’d jump ship to another brand if their current make boosted prices by $10,000. The second biggest cause for switching was fuel economy, which 47 percent of buyers said would make them change up.One of the factors driving prices of trucks up — apart from luxury touches like leather and wood — is the massive increase in the amount of tech that trucks have seen in recent years. Whether that is something as simple as a touchscreen infotainment system or as complex as Chevrolet’s super-advanced cylinder deactivation system, it all costs money. Still, a slim majority of 54 percent of buyers approve of how tech-laden their trucks are. “With pickup truck prices on the rise, many owners are reconsidering their current brand, or in some cases whether they will repurchase a pickup at all,” said Madison Gross, director of consumer insights at CarGurus, in a statement. “While truck owners still have strong brand and category loyalty, the challenge for car manufacturers and dealerships is that loyalty is increasingly less reliable as a driver of sales.” The 2020 Ford F-Series Super Duty gets a new look and more capability 2020 BMW M340i review: A dash of M makes everything better Ram Chevrolet Ford Nissan Toyota
The physicists, Anthony Bartolotta, a graduate student at Caltech, and Sebastian Deffner, Physics Professor at the University of Maryland Baltimore County, have written a paper on the Jarzynski equality for quantum field theories that will be published in an upcoming issue of Physical Review X.The work address one of the biggest challenges in fundamental physics, which is to determine how the laws of classical thermodynamics can be extended to the quantum scale. Understanding work and heat flow at the level of subatomic particles would benefit a wide range of areas, from designing nanoscale materials to understanding the evolution of the early universe.As Bartolotta and Deffner explain in their paper, in contrast to the large leaps made in the “microscopic theories” of classical and quantum mechanics during the past century, the development of thermodynamics has been rather stagnant over that time. Although thermodynamics was originally developed to describe the relation between energy and work, the theory traditionally applies only to systems that change infinitely slowly. In 1997, physicist Christopher Jarzynski at the University of Maryland College Park introduced a way to extend thermodynamics to systems in which heat and energy transfer processes occur at any rate. The fluctuation theorems, the most prominent of which is now called the Jarzynski equality, have made it possible to understand the thermodynamics of a wider range of smaller, yet still classical, systems.”Thermodynamics is a phenomenological theory to describe the average behavior of heat and work,” Deffner told Phys.org. “Originally designed to improve big, stinky heat engines, it was not capable of describing small systems and systems that operate far from equilibrium. The Jarzynski equality dramatically broadened the scope of thermodynamics and laid the groundwork for stochastic thermodynamics, which is a new and very active branch of research.” Thermodynamic laws that describe heat and energy are being extended to the quantum scale.

Photograph by Paweł Kadysz Stochastic thermodynamics deals with classical thermodynamic concepts such as work, heat, and entropy, but on the level of fluctuating trajectories of atoms and molecules. This more detailed picture is particularly important for understanding thermodynamics in small-scale systems, which is also the realm of various emerging applications.It wasn’t for another decade, however, until the Jarzynski equality and other fluctuation theorems were extended to the quantum scale, at least up to a point. In 2007, researchers determined how quantum effects modify the usual interpretation of work. However, many questions still remain and overall, the area of quantum stochastic thermodynamics is still incomplete. Against this backdrop, the results of the new study represent a significant advance.”Now, in 2018 we have taken the next big step forward,” Deffner said. “We have generalized stochastic thermodynamics to quantum field theories (QFT). In a certain sense we have extended stochastic thermodynamics to its ultimate range of validity, since QFT is designed to be the most fundamental theory in physics.”One of the keys to the achievement was to develop a completely novel graph theoretic approach, which allowed the researchers to classify and combine the Feynman diagrams used to describe particle behavior in a new way. More specifically, the approach makes it possible to precisely calculate infinite sums of all the possible permutations (or arrangements) of disconnected subdiagrams describing the particle trajectories.”The quantity we were interested in, the work, is different than the quantities usually calculated by particle theorists and thus required a different approach,” Bartolotta said.The physicists expect that the results will allow other scientists to apply the fluctuation theorems to a wide variety of problems at the forefront of physics, such as in particle physics, cosmology, and condensed matter physics. This includes studying things like quantum engines, the thermodynamic properties of graphene, and the quark gluon plasma produced in heavy ion colliders—some of the most extreme conditions found in nature.In the future, the physicists plan to generalize their approach to a wider variety of quantum field theories, which will open up even further possibilities.

Physicists have extended one of the most prominent fluctuation theorems of classical stochastic thermodynamics, the Jarzynski equality, to quantum field theory. As quantum field theory is considered to be the most fundamental theory in physics, the results allow the knowledge of stochastic thermodynamics to be applied, for the first time, across the full range of energy and length scales.
