We’ll find out soon.A Denver-based company called Royalty Exchange will auction royalties from GRAMMY-winning rapper Eminem’s songs released from 1999 to 2013 as part of a deal set up by the production duo the Funky Bass Team, aka FBT Productions. Royalty Shares Of Eminem’s Songs Go Up For Sale royalty-shares-eminems-songs-put-sale Em was signed to FBT before he became a superstar, and now the duo will put portions of future earnings up for bid in October as part of a new company called Royalty Flow. Just as on Wall Street, Royalty Flow will file for its initial public offering on Monday, leaving it up to the U.S. Securities and Exchange Commission to determine its fate. If it’s accepted, anyone with the cash could buy 150 shares or more of Eminem’s catalog at the minimum price of $2,250, according to Rolling Stone.This isn’t the first instance of royalties being sold in this fashion, and auctions like this could lead to a new trend in monetizing musical catalogs. Royalty Exchange has already sold shares of Wiz Khalifa, Chris Brown and Ariana Grande songs. But considering Eminem’s proven hits like “My Name Is” and “Lose Yourself” are involved, this auction moves the model into new territory.With this potentially exciting new opportunity for fans and fortune-seekers alike to own a piece of the pie comes a bigger moral question of how intellectual property rights should be dealt with.Inevitably, some will feel there should be a deeper sensitivity considering the expressive nature of the commodity involved, while others see this as the latest iteration of the industry’s ever-changing monetization models. Time will tell.Read More: 5 Reasons “The Eminem Show” Is A Classic Album Twitter Facebook
View of damages in a supermarket in Valencia, Carabobo State, on Friday, the day after anti-government protesters looted stores, set fire to cars and clashed with police, leaving at least five people injured, and one dead after being hit in the head by a projectile. Photo: AFPA young man died Friday after he was injured in violence as looting broke out in impoverished Venezuelan cities, an official said, bringing the toll from unrest in more than a month of anti-government protests to at least 36.Hecder Lugo Perez, 22, died after he was hit in the head by a projectile in the northwestern city of Valencia, sources at the Valles de San Diego medical clinic said. City Mayor Enzo Scarano confirmed his death.Mass protests erupted on April 1 by demonstrators demanding elections to remove President Nicolas Maduro. They blame him for an economic crisis that has caused shortages of food, medicine and other basics.Anger boiled over Friday in the western municipality of Rosario de Perija, where young protesters burned, pulled down and then smashed a statue of former president Hugo Chavez, Maduro’s late predecessor and mentor, according to video posted on social media showing the incident in a public square.Looting broke out this week in cities such as Valencia, which looked like a disaster zone with bars on shop windows bent and windows broken.“There was a crowd of them. They broke through the walls and took everything. They destroyed everything” before police came and fired tear gas to disperse the looters, said Nuvia Torrealba, 42, who worked in a bakery.“My bosses have lost their home and we are out of a job. It was horrible.”Residents were stockpiling food, water and fuel. At least 70 stores have been raided since Tuesday, the Valencia chamber of commerce said.“They are taking advantage of the protests to go out and rob,” said Magaly Oliveros, a 64-year-old housewife in Valencia.“Today we are hungry, and tomorrow we will be hungrier still because there is nothing.”Army allegationsMaduro is resisting opposition demands for elections.Each side accuses the other of using armed groups to sow violence in the demonstrations.Maduro has the public backing of the military high command, which analysts say is key to resisting the protests.However, senior opposition leader Henrique Capriles said on Friday that 85 mid-ranking army officers have been detained for opposing moves to crack down on protesters.He cited information he said was given by the officers’ families.Weekend protestsMaduro’s opponents called for women to march on Saturday dressed in white, a traditional show of defiance against what they brand a repressive government.“The regime is falling,” said Lilian Tintori, wife of jailed opposition leader Leopoldo Lopez, outside the prison near Caracas where she was demanding to see her husband.“It has no strength and is showing its worst side, using weapons because it is does not have right on its side.”The president has launched moves to reform the constitution, further angering the opposition, which says he is trying to dodge elections.He says the economic crisis is a US-backed conspiracy to topple him and install a right-wing government.“We will not let a fascist regime be set up here,” said Elias Jaua, the official appointed to lead a presidential commission on the constitutional reforms.Capriles said the opposition will take no part in the constitutional discussions.The celebrity Venezuelan conductor Gustavo Dudamel, director of the Los Angeles Philharmonic, added his voice to calls for an end to the violence on Thursday.He called for Maduro to “listen to the voice of the Venezuelan people”, in a message posted on Facebook.

That is about to change, with the latest split-cycle engines from the Scuderi Group offering greater fuel efficiency and up to 80 percent reduction in NOx emissions and 50 percent reduction in CO2. Split-cycle engines feature paired cylinders, so a four-cylinder engine has two sets of paired cylinders working together, with a crossover passage linking the two cylinders in each pair to each other. The four strokes of the engine are split into two groups, with the left cylinder handling intake and compression and the second handling combustion and exhaust. The Scuderi™ Air-Hybrid design adds an air storage tank and controls that allow it to recapture and store the energy lost as the engine operates.The new design solves some of the problems that have hampered previous split-cycle designs. The low volume breathing problem is solved by outward-opening pneumatic valves and a reduction in the clearance between the piston and cylinder head to under 1 mm, which means virtually 100 percent of the compressed air is pushed out of the cylinder.

Scuderi says the technology should be licensed and on the road within three years.

Firing ATDC is achieved by high pressure air entering the cylinder and resulting in massive turbulence. Firing ATDC is a cleaner burn that also dramatically reduces NOx emissions and improves fuel efficiency.The Southwest Research Institute (SwRI) has been testing a 1-liter, two-cylinder engine for almost a year. The preliminary results suggest a 30-36 percent increase in fuel efficiency for the naturally aspirated Scuderi™ Air-Hybrid and a 25 percent increase for the base model. The test engine generates 135 horsepower at 6,000 RPM, which is similar to results of bigger and more fuel-hungry cars.

The ultimate speed limit arises from the length of the shortest geodesic path between two states, which here is the solid red line. This distance corresponds to the minimum time needed for a system to evolve from one state to another.

Physicists quantify the usefulness of ‘quantum weirdness’ Citation: Physicists discover an infinite number of quantum speed limits (2016, June 3) retrieved 18 August 2019 from https://phys.org/news/2016-06-physicists-infinite-quantum-limits.html Although physicists have been investigating different quantum speed limits for different types of quantum systems, it has not been clear what the best way to do this is, or how many different quantum speed limits there are.Now in a new paper published in Physical Review X, Diego Paiva Pires et al., from the UK and Brazil, have used techniques from information geometry to show that there are an infinite number of quantum speed limits. They also develop a way to determine which of these speed limits are the strictest, or in other words, which speed limits offer the tightest lower bounds. As the researchers explain, the search for the ultimate quantum speed limits is closely related to the very nature of time itself. “In recent years, there has been an intense theoretical and experimental research activity to understand, on one hand, a fundamental concept in quantum mechanics such as time, and to devise, on the other hand, efficient schemes for the implementation of quantum technologies,” coauthor Gerardo Adesso, at the University of Nottingham, told Phys.org. “A basic question that combines and underpins both areas of research is: ‘How fast can a quantum system evolve in time?’ Establishing general and tight quantum speed limits is crucial to assess how fast quantum technologies can ultimately be, and can accordingly guide in the design of more efficient protocols operating at or close to the ultimate bounds.” In order to determine how fast a quantum system can evolve from one state to another, it’s necessary to be able to distinguish between the two states, and there are multiple ways to do this. In the new study, the physicists used a general method based on information geometry. From a geometric perspective, two distinguishable states can be represented by two points on the surface of some shape, such as a sphere or other manifold. Previous research has shown that there are an infinite number of corresponding metrics that can be used to measure the distinguishability of two quantum states.In the new study, the physicists have shown that each of these metrics corresponds to a different quantum speed limit. The “strictest” quantum speed limit is determined by the metric that gives the shortest distance (also known as a ‘geodesic’) between the two points, or states, as measured along the manifold’s curved surface. “A different quantum speed limit arises from each of these metrics in such a way that the tightest bound for a given dynamics is specified by the metric whose geodesic is best tailored to the given dynamical path,” explained coauthor Marco Cianciaruso, also at Nottingham.Overall, the new approach unifies most of the previous results by interpreting them under a single, new framework. On one hand, the researchers could derive the tightest bounds to date on quantum speed limits for some relevant instances, such as quantum bits undergoing dissipative and decohering evolutions. On the other hand, they could also show that bounds that have been previously proposed for other instances are truly the optimal bounds—no tighter bounds will ever be found. In the future, the researchers plan to experimentally investigate the quantum speed limits derived here using nuclear magnetic resonance (NMR) techniques. “Our findings are expected to have an impact on the fields of quantum information, computation, simulation, and metrology,” said Diogo Soares-Pinto at the Sao Carlos Institute of Physics, who supervised the project. (Phys.org)—In order to determine how fast quantum technologies can ultimately operate, physicists have established the concept of “quantum speed limits.” Quantum speed limits impose limitations on how fast a quantum system can transition from one state to another, so that such a transition requires a minimum amount of time (typically on the order of nanoseconds). This means, for example, that a future quantum computer will not be able to perform computations faster than a certain time determined by these limits. © 2016 Phys.org Explore further
