The UC Santa Barbara group used a microwave coplanar waveguide resonator with a superconducting qubit in order to provide the control needed to create, and to measure the decay of, the Fock states. “Learning more about the fundamentals of these states can provide us with some very practical information.” The group’s results are reported in Physical Review Letters: “Measurement of the Decay of Fock States in a Superconducting Quantum Circuit.” Haohua Wang, a postdoctoral scientist in the Martinis group, was the lead researcher on the experiment.“What we found,” Cleland continues, “is that the time decay of these Fock states follows precisely what is expected in theory. It gives us some good information about how these states work, as well as a foundation on which we can build elements for a quantum computer.”Cleland also points out that the work done by the Martinis group produced more than one photon for the experiment, and that hadn’t been done before. “Typically experiments use a combination of a zero photon Fock state and a one photon state. No one until now has developed the technology to show that you could controllably create states with more than one photon. We did.” The Martinis group results indicate that it is possible to control Fock states with up to 15 photons.Because Fock states are the fundamental quantum states of a harmonic oscillator, they are important to study. “These oscillators occur in many natural systems,” Cleland explains. “The electronic versions we studied are known as electromagnetic resonators. These resonators have a number of uses for quantum communications and computing.”One of the uses that such resonators might have includes memory elements for quantum computing. “Of course,” Cleland qualifies, “no one is close to doing the kinds of computations we’d like to be able to do, but this is a step that could get us there down the road.” The memory elements he refers to need a certain level of control that the Martinis group was able to develop with their present experimental setup. “The applications associated with having more than one photon – one of the things we showed in our experiment – are not as clear as a one photon memory function,” Cleland admits. But he does believe that there could be uses for such states in quantum simulation. “Right now, simulating the interactions between molecules requires giant computers to work a long time. It’s not very efficient. Quantum simulation could help us more efficiently see accurate interactions with a relatively simple quantum simulator.” Cleland concedes that the Santa Barbara group is more interested in building a quantum computer, even though he can see other possible uses for the work they have done. “We’ve created a level of control that might make it possible to program quantum memory, and that is exciting itself.”More Information: H.

More information: Sony press release: pro.sony.com/bbsccms/assets/fi … _series-HPA_2011.pdf The new monitors will not be cheap. The 25-inch model is expected to cost $28,840. Despite how high that number seems when you compare it to the average home LCD monitor, it will only cost about 10 percent more than the LCD monitors that are currently in production for the film industry. OLED screens are already common in smaller gadgets, such as cell phones and other handheld devices. This document is subject to copyright.

The monitor, which was designed for the TV and film production industries, is set to go on sale on May 1. They are expected to be used in locations such as editing bays, satellite trucks and broadcasting control rooms. The OLED screen will have a 25-inch screen. A second model, one that features a smaller 17-inch screen, is expected to go on sale on the first of July. Explore further The OLED is a flat-panel screen technology made up of cells that contain an organic material. The material used omits its own light. This allows the screens to be made thinner than the more well-known LCDs flat screens. The OLED screens are also more power efficient than LCD screens. OLED’s are significantly more expensive to produce than LCD screens, which has hindered their wide-scale adoption, but they handle fast-moving images better. The colors also appear richer on the OLED screens when compared to images shown on the LCDs. Sony hosted a live demonstration of the new monitors at its Tokyo headquarters and played the same video footage on OLED and LCD monitors side-by-side to illustrate this point.

Nanoporous structure of 1. Credit: Science Advances (2015). DOI: 10.1126/sciadv.1500421 As the researchers note, most of the effort currently put into making coal a cleaner fuel source revolve around capturing the carbon dioxide that is released when coal is burned. They suggest a better alternative might be to separate out the carbon dioxide as part of the burning process, leaving clean hydrogen gas as the actual fuel used to heat water to turn turbines.The new MOF proposed by the team involves the use of nickel and isonicotinic acid as a sponge to pull the carbon from the coal. It would be part of a process that involves burning the coal with steam under cycles of high and low pressure. They claim their approach is twice as efficient as other sponge methods and that it is also simpler, faster to make and is not harmed by moisture, making it easy to store and transfer materials.The big catch with the process is what to do with the carbon dioxide that is separated out—capturing it, holding on to it, transporting it and ultimately storing it would represent a substantial cost outlay for any given utility, which at this point, would appear to be prohibitively high for plants that are attempting to keep electricity costs down in places where locals could not afford higher rates, such as is the case in parts of India, China and many third-world countries.In speaking with the press, one of the researchers, Ramanathan Vaidhyanathan, suggested that this might be an issue to be brought before an international forum such as the recent Paris Climate Change Conference. He notes that rather than storing the carbon dioxide, it might be used in industrial applications, such as oil extraction or for creating new compounds. More information: S. Nandi et al. A single-ligand ultra-microporous MOF for precombustion CO2 capture and hydrogen purification, Science Advances (2015). DOI: 10.1126/sciadv.1500421AbstractMetal organic frameworks (MOFs) built from a single small ligand typically have high stability, are rigid, and have syntheses that are often simple and easily scalable. However, they are normally ultra-microporous and do not have large surface areas amenable to gas separation applications. We report an ultra-microporous (3.5 and 4.8 Å pores) Ni-(4-pyridylcarboxylate)2 with a cubic framework that exhibits exceptionally high CO2/H2 selectivities (285 for 20:80 and 230 for 40:60 mixtures at 10 bar, 40°C) and working capacities (3.95 mmol/g), making it suitable for hydrogen purification under typical precombustion CO2 capture conditions (1- to 10-bar pressure swing). It exhibits facile CO2 adsorption-desorption cycling and has CO2 self-diffusivities of ~3 × 10−9 m2/s, which is two orders higher than that of zeolite 13X and comparable to other top-performing MOFs for this application. Simulations reveal a high density of binding sites that allow for favorable CO2-CO2 interactions and large cooperative binding energies. Ultra-micropores generated by a small ligand ensures hydrolytic, hydrostatic stabilities, shelf life, and stability toward humid gas streams. © 2015 Phys.org Journal information: Science Advances Citation: Researchers propose new kind of MOF to clean coal burned in power plants (2015, December 21) retrieved 18 August 2019 from https://phys.org/news/2015-12-kind-mof-coal-power.html Explore further (Phys.org)—A small team of researchers with members from India, Canada, the U.S. and Germany has come up with a new kind of metal-organic framework (MOF) to keep carbon in coal from entering the atmosphere when it is burned in power plants—thus reducing pollution and problems with global warming.

That ‘thing’ behind the curtains or between the sheets or better off behind the stage is what Atul Kumar has put up this time in his play titled Noises Off. After creating a wave with his cult Piya Behroopiya, the director gears up to put together an act to see what transpires between actors, directors, stage hands etc. ‘It is a play within a play about a theatre company trying to put up a sex farce but because of their incompetence the entire thing turns into a big fiasco. It’s a comical look at what we all go through as theatre makers. Mainly exploring the noise that is made backstage (talking, fighting, constructing, electric) or as we say in theatre language off-stage as opposed to on-stage.’ said Atul. Also Read – ‘Playing Jojo was emotionally exhausting’Originally written by Michael Frayn, Atul directed the version ten years back and calls it one of the most translated and played comedy in the world- obviously a favourite of the theatre goers.‘I think a long time back Barry John directed a production in Delhi with Lilette Dubey and Shahrukh Khan acting in it,’ he added.So what really inspired this play? ‘It is extremely clever and funny look at what we all as theatre makers go through in our lives while at work and at home. It is a play I have liked since the first time I read it ten years back and I think I will direct it again and again. Whatever be the age and wherever you might be in this world if you do theatre it is difficult to not fall in love with Also Read – Leslie doing new comedy special with NetflixNoises Off.’‘We worked very quickly this time- we prepared the play within a month. We rehearsed for 10 hours or so first fortnight and then half a day in the end,’ he added. The play has a 70’s look with dress and makeup. And it was exciting to light up the backstage when the stage turns around to show you the backstage act.Any expectations or apprehensions from the Delhi audience? ‘They should just come with open hearts and open minds. Noises Off is no deep piece of literature- it is very simply a funny look at the follies of a theatre company- its like saying lets look at this classicaly- a man is going to slip over a banana skin and it is still funny today,’ Atul quipped.Where- Kamani AuditoriumWhen- 17- 18 AugustTimings- 7.30 pm onwards

Kolkata: Chief Minister Mamata Banerjee on Thursday announced setting up of a monument at Marichjhapi Island in the Sunderbans in memory of the incident of forcible eviction of Bangladeshi refugees in 1979 and the subsequent deaths of around thousands in police firing, starvation and disease. The response came from Banerjee during the question answer session in the Assembly about tourism projects in South 24-Parganas. Responding to another poser on whether the government is planning to host a light and sound show on Plassey ground, where the 1757 war of independence was fought similar to what is hosted at Motijheel, Banerjee said the proposal is under consideration. The response from the Chief Minister came after Tourism minister Goutam Deb failed to deliver proper information regarding tourism projects.

While our entire focus is on how economic slow down and demonetization has engulfed the growth of real estate market, we are completely ignoring another crucial factor which is constantly and silently dominating the fate of real estate as well. Vastu experts. We as Indians are prone towards making impulsive emotional investments. Today, even as tenants look out for a residential apartment, office space or retail spaces, their first concern is Vastu. But if Vastu is considered as a bioplasmic architectural science, which has tools to help balance the five elements of nature controlling our life, then science should make things simple rather than complex and non-progressive, isn’t it? Or are we operating from fear psychosis factor by the so-called Vastu experts? Also Read – Add new books to your shelfTo understand how the Vastu hysteria created by these so-called Vastu experts can be resolved, Nilangshu Haldar – a renowned Maha Vastu expert from Kolkata and an independent Vastu consultant who works closely with numerous established developers in the city – came forward to clarify a few facts.Haldar clearly explains that Vastu corrections can be done on three levels. “If we happen to miss the corrections at the first level or the second level, we can still make the changes at the third level and these corrections will give us the same success rate at any level,” explained the Maha Vastu expert. Also Read – Over 2 hours screen time daily will make your kids impulsiveHe further elaborates, “The first level of Vastu correction is made at the time of purchasing of land. As uneven lands are trimmed and pruned to get a shape – it could be rectangular, square or even L-shaped. The second level is where an amalgamation of modern architecture and ancient Vastu-shastra work hand-in-hand to create a Vastu friendly construction with an attractive project design. Here again, the designs always depend on various factors like construction ROIs, facilities to be provided in the projects, to name a few. Hence, it is not always possible to keep the Vastu compliance as per the desire of the end users. Still, corrections can be made at the third level with colours and placement of various Vastu tools. Therefore, when people say “Is building ka Vastu thik nahi hai (the Vastu of this building is not good)”, then we should not forget that corrective measures are also available, with our Vedic science of Vastu-shastra.” In fact, there are other important details to be seen while choosing a property than to just be a Vastu fanatic. The material used for constructions, the foundation of the building, local infrastructural development and many other things needs to be considered before investing in a property. There are shopping malls, commercial complexes residential buildings that are vacant. Is it because the Vastu is not correct? Or is it just our inner fear created by external forces in the form of Vastu experts? If that’s the case, then what did the Vastu expert do at the first and second level? To all of these questions, Nilangshu replied, “An experienced and knowledgeable Vastu consultant should be well versed with the remedies to Vastu problems”. Among the real estate agents, competition developers, and rival property brokers, it has become a common practice to malign a property by spreading false rumours about a property – which in turn, creates difficult implications on the overall consumption in real estate.Originally, Vastu-shastra was used to make life prosperous and successful. But now, even with various real estate websites educating the prospective buyers about Vastu, fear and indecisiveness is increasing in our choices. The concern here is not Vastu, but the obsession that is creating a parallel corrupt industry by these so-called Vastu experts. It’s high time we wake up and use our intelligence, and use Vastu to our advantage.
Kolkata: Veteran Bengali actor Chinmoy Roy has died, family sources said Monday. He was 79. Roy died of cardiac arrest at his Salt Lake residence at around 10:20 pm Sunday, they said. Roy is survived by his son and daughter, his wife actress Jui Banerjee had died a few years back. Born in Kumilla district in present day Bangladesh in 1940, Roy had started his career in Bengali films in the 60s and became indispensable to the film makers for his portrayal of comic characters retaining the very essence of Bengaliness and a certain culture. He was equally noticed along with big names like Soumitra Chatterjee and Rabi Ghosh in a classic comedy like Basanta Bilap or in Dhonni Meye. Roy had been cast by Satyajit Ray in a small role in children’s fantasy Goopy Gyne Bagha Byne. He immortalised the character of Tenyda in the film Charmurti which became a major hit in the 1980s.
