In a somewhat unexpected turn of events, it emerged on Monday that Arrow Light Rail — the existing operators of Nottingham, England’s Express Transit (NET) system — were to have their contract ripped up, after the preferred bidder for the construction of Phase 2 was announced. The change means that the entire network will be able to be integrated throughout, rather than having two operators effectively running two separate systems.

Nottingham City Council have selected Tramlink Nottingham as their preferred bidder to construct and operate the NET Phase Two lines to Chilwell and Clifton, and will now enter talks with the consortium, made up of Alstom, Keolis, Trent Barton, VINCI Construction UK, OFI Infravia and Meridiam Infrastructure, to finalise the exact details of the contract. It is expected that the concessionary contract will be awarded during the coming summer, with construction starting before the end of the year. The contract will run for 23 years.

Tramlink Nottingham chairman Roger Harrison said: “Building on Arrow’s successful legacy, we are excited to be taking forward the next chapter in Nottingham’s tram story.

“Our focus now will be on working with Nottingham City Council to ensure NET Phase Two can be introduced at the earliest opportunity.”

The reshuffle of operating consortium means that Nottingham City Transport (NCT) — the main provider of bus services within Nottingham — will have no part to play in the extended network, despite the numerous awards and high satisfaction levels NET has had since its opening; it is the only one of Britain’s five light rail networks to be an instant success.

“We’re obviously very disappointed not to be part of the selected preferred consortium. Nottingham’s tram has won numerous awards and after seven years passengers continue to praise its operation. We would have relished the opportunity to have been part of this continuing success,” said NCT’s Managing Director Mark Fowles.

But the council stresses that they are still committed to the future of the company.

“This decision in no way reflects the excellent job Arrow Light Rail Limited has done operating the tram since its launch. Annual customer satisfaction figures remain very high and this is testament to this operation,” added Jane Todd. “The decision to appoint a new consortium to build and operate the extended tram network was made on the basis of selecting the best proposal to meet the council’s objectives for the future of the tram system. The overall offer from the Tramlink Nottingham consortium was stronger. Although disappointing for NCT it is nonetheless good news for the integration of public transport services that the city’s other major bus operator, Trent Barton, is part of the preferred bidder. I am certain NCT will continue to provide award winning bus services for the people of Nottingham.”

Staff currently employed by Arrow Light Rail are expected to be transferred over to Tramlink Nottingham around August, when further details of the contract will become clear. Other changes that are proposed for the network include ‘smart card’ ticketing — similar to the highly successful Oyster scheme that is in use across Transport for London’s service — and the phasing out of tram conductors in favour of on-platform ticketing machines. Current conductors will be offered new roles within the company, though talks are still on-going about how to combat any potential fare-dodgers.

Furthermore, an additional 22 tram vehicles will be built by consortium member Alstom for the extended network, though these will be of a different design to the 15 existing vehicles, which were built by Bombardier to their Incentro design for the system’s opening. The new trams will be part of Alstom’s Citadis family, and will bring the total tram fleet to 37. This will also allow for service frequencies to be increased and for overcrowding to be eased at peak times.

Ticketing arrangements for the network will also change when the new consortium takes over. Currently, combined tickets, cards and passes can be used for the tram and NCT buses, but these are due to be phased out and replaced with the new smart cards in time for the opening of the extensions. Prior to that, passengers will be able to use combined tickets, cards and passes for the tram and Trent Barton buses, in a similar arrangement to that which is already offered for NCT.

Pat Armstrong, director for NET, said: “The move is very much towards more sophisticated smart ticketing, like the Oyster card in London. You use the same card but the money goes back to the company you are travelling with.”

The extended network, new trams and numerous other changes should be fully operational by the end of 2014, but NET users and tramway enthusiasts had mixed views on the matter:

“I think it’s a bad idea to phase out the conductors,” said Andrew Blood, assistant editor of the Tramways Monthly e-magazine, “Not only do they help with revenue protection, but they are also responsible for the high passenger satisfaction levels on the system. In short, they keep tram users feeling safe.”

Greg Smith, from Hucknall, was pleased that service levels were going to increase: “The fact that the trams will be running more frequently is a massive bonus in my eyes. The service we get at [the Hucknall] end of the line is great already, but if [the trams] are running more frequently it’s just another advantage of the system over the bus.” But he was also wary of on-platform ticketing being brought into place: “I’m not sure that losing the conductors in favour of ticket machines is the way to go, though.”

Imagine coming back from a camping trip in the desert. Then a few months later you notice in your photos from the trip that you camped inside a giant impact crater so big that no one documented it before. Could it happen?

During several trips to the Black Rock Desert, mostly while supporting the Stratofox Aerospace Tracking Team for suborbital space rocket launch efforts, Ian Kluft KO6YQ noticed some oddities in rock formations. He had a little experience with volcanoes, and some rocks in the area looked unusual. There seemed to be some lava here and there – but where was the volcano? He observed that even a large caldera should have mostly volcanic rocks. He then noticed some curved geographic structures in satellite imagery which made him curious if it might be an impact crater.

A TV documentary about meteor impacts mentioned some characteristics of impact craters. He went to the Internet to learn more. He noticed some of his own pictures of the area had cone shaped structures which might be “shatter cones” due to an impact shock wave that passed through the rocks. Discussion with others produced suggestions and volunteers who joined the effort. More circular features in satellite photographs were found. Igneous dikes through white layers of rock had been described and were visible in many photos.

The possible impact crater is 30 miles (48 km) wide east-to-west and 40 miles (64 km) north-to-south centered around 40.984045 N, 118.916016 W. That is in northwestern Nevada halfway between Reno and the Oregon border. The apparent ancient geological structure is so old that much of it is eroded away. The forces that eroded the Black Rock Desert itself, whether glacier or stream, have apparently cut through the crater rims and floor to do it.

Following an expedition to the area in late January, more possible shatter cones were observed in one of the rock samples collected. These are only formed by the shock wave of an impact event or nuclear explosion. The nearest nuclear test was underground at Sand Springs Range in central Nevada. Atmospheric tests at the Nevada Test Site were at the southern, and opposite, end of the state. So that points toward an impact if confirmed. But professional geologists will want to have the final word on confirming them.

In addition to shatter cones, rock samples were thought to contain shocked quartz because the criss-cross fractures looked like examples in online documents. But this group of volunteers doesn’t have equipment for proper photography of shocked quartz. If found, that would be another way to prove the impact origin of the rocks.

Columnar jointed columns hundreds of feet tall appear on some bluffs in locations that appeared consistent with part of a slowly cooling crater floor. But that alone only helps as part of a bigger picture, because volcanoes can have lava cool in columnar joints as well.

They also found local geological studies which described oddities which could be explained by an impact event. Layers of rocks in the mining district called Sulphur left geologists with a mystery about the cause of chemical alterations since 1980. The group compared it with information in online geological texts like “Traces of Catastrophe” by Dr Bevan M French of the Smithsonian Institution. Layers of impact ejecta seemed to explain the rock layers better than the previous theory about acid uniformly cooking the rocks across the region, and only in one layer of rocks. A separate 1980 study 40 miles away identified an immense air-fall tuff layer in the Soldier Meadows area as having been deposited in a single unit, yet couldn’t locate the volcano which produced this enormous volume. Fault diagrams published online by a mining operation at Sulphur on the edge of the circular structure from the satellite photo also look like curved terraced faults in the wall of a crater.

The mining geologists who wrote papers from 1980 to 2002 had not mentioned the possibility of a crater. But they were each gathering single puzzling pieces of information. A larger image seemed to be forming when putting the pieces together. The group hopes the information will be helpful to geologists who do further work in the region.

The theory hasn’t been put to any test by professionals yet. Some responses point out that the elliptical region reported as the possible impact crater could also be the volcanic caldera that the 1980 study was looking for. If so, such a large volcanic caldera would still be a significant discovery for the region.

This will remain officially a mystery for a while until the professional geologists get to study it. There is a lot of information available online for those who are interested.

One year ago today, September 7, 2004, the Wikimedia Commons project was presented to the public. Wikimedia Commons, or simply Commons, is a repository for multimedia files that include images, videos, computer animations, and music as well as spoken texts. They currently count more than 232,000 such files.

All of Commons content is published under a free licence, so the use of its files is permitted outside the project itself. Its main mission is to provide the international Wikipedias with images. Like Wikipedia, the Commons is based on a simple wiki principle that permits every user to contribute and change content. The project is organized into so-called gallery pages, and/or by adding files into categories organized in multiple topics that help facilitate the speedy location of desired files. Often it exists already a direct link from the Wikipedia page to the corresponding page in the Commons.

The Wikimedia Commons proposal was originated by the German Erik Möller, (Eloquence), in March 2004. Eloquence was until recently the Chief Research Officer of the Wikimedia Foundation. Up until the launch of Commons, it was time consuming to use material from one Wikipedia language project in a sister project of a different language. Each file had to be uploaded into each language edition of Wikipedia, and be described and licensed again. The goal was to reduce this redundant effort into one upload, which it can be said that this was successful.

The language in use on the project’s Main Page is English because it is an international project, but many information pages exist in multiple languages. Judging by the experience of other Wikimedia Foundation projects, it is only a question of time before further localization occurs at Commons. This will make it easier for users with fewer skills in foreign languages to also contribute files.

The content in the Commons is growing at a rapid pace. Within the last month alone, the number of images and other files has grown by more than 43,000. This represents a 22,7 % increase in relation to the prior month. While the Wikipedia projects usually compare themselves with the more widely known encyclopedias like Britannica and Brockhaus, a competitor Commons would likely be considered the huge commercial photo archives like Getty Images and Corbis, who possess more than 70 million images each. In relation to them, the Commons is very small at the moment. However, most of the important buildings and landmarks world wide are already featured in its database.

Like other Wikimedia Foundation projects, the Commons face certain challenges and problems. Sometimes people upload offensive images. The community has had to establish clear criteria about which content is acceptable, and which is not. There should not be unfair censorship. Obvious transgressions can be pointed out by anybody, and they are usually deleted rapidly by the administrators.

A sensitive topic is copyrights, and the rights of the owner of the pictured images. International rules have not yet been made compatible. In certain ways, the Wikimedia Foundation opens new territory in the area of intellectual property. Before Commons, it was almost exclusively a domain of professionals to publish images who were well aware of the legal issues. Now it is possible for huge numbers of photo amateurs to publish. Like with offensive content, obvious violations of copyright are deleted the moment they are brought to notice of the administrators. However, it is quite possible there will be an upcoming international debate if the free publication of certain content, e.g. images of national heritage objects, is in the overwhelming public interest. In cases such as this, private interests which might prevent publication are of lesser importance.

The contribution of Wikimedia Commons to a wide array of issues in research, reporting, education, tourism or others, at a global scale, is difficult to fathom at the moment. Most likely though the impact will be gigantic.

Private Meredith Simms, 18-years-old, died yesterday when the New Zealand Army Mercedes-Benz Unimog truck he was travelling in left the road and fell 100-metres down a steep bank 2.30 p.m. yesterday (NZST), coming to rest on railway tracks. The soldier driving the truck was critically injured and was flown by the Westpac Rescue Helicopter to Wellington Hospital, where he is being treated for spinal cord injuries.

The Unimog was travelling in a convoy 14-kilometres southeast of Blenheim on State Highway 1, Weld Pass.

The New Zealand police have launched an inquiry into the fatal accident. The Unimog has been removed from the scene of the crash and will now be examined. The police say that they will guard the scene and finish examining it today.

The accident occurred when the Unimog was returning back to the Burnham Military Camp, Christchurch, where all soldiers were from. It followed a ten day exercise which involved 15 vehicles in Marlborough. The other soldiers went to the RNZAF Base Woodbourne base to receive counselling from a military chaplain, military psychologist and police victim support, they are returning to Burnham today.

The family of the deceased said their son “died doing what he loved,” and have requested privacy.

Simms’ death has been referred to a coroner.

Since 1994 there have been eight fatal accidents involving Unimogs.

Buffalo, New York —Wikinews was the first to tell you that the Elmwood Village Hotel development in Buffalo, New York was to undergo “significant changes”.

The Elmwood Village Hotel is a proposed project that would be placed at Elmwood and Forest Aves. in Buffalo. In order for the development to take place, at least five buildings that house both businesses and residents, must be demolished.

To confirm and to get more information about the changes, Wikinews interviewed Eva Hassett, Vice President of Savarino Construction Services Corporation, the development company in charge of building the hotel.

Wikinews: The hotel proposal is being redesigned. Could you comment on that? What changes are being made? Are they significant?

Eva Hassett: The hotel has been resized as a 72-room, four story building. This is 10% smaller in number of rooms and a full story lower. We are also redesigning the facades in a way that will minimize the mass – more of a vertical feeling than horizontal. Different materials, windows, details. The smaller size of the hotel also makes the number of on-site parking spaces more appropriate and hopefully represents less of a challenge to an already difficult parking situation.

WN: Will you still be going before the city’s planning board as scheduled on February 28? Same for the Common Council?

Hassett: We will be on the Planning Board agenda this Tuesday morning but I do not expect that the Board will vote on the item that morning. I think we will be mainly explaining the new design and hearing input/questions.

WN: Will there be anymore public meetings?

Hassett: We would be happy to do one more big public meeting. We will be talking to Forever Elmwood about that on Monday (February 27, 2006). We would like to see if there is support for the new design and we also want to honor the public’s request for another meeting. I am hopeful that meeting can take place the week of March 6th.

WN: Is Savarino considering Mr. Rocco Termini’s design/proposal? If no, do you (Savarino) support/oppose?

Hassett: We are hopeful that we can build the hotel as redesigned. We think it would be a great addition to the Elmwood Ave. area, a good way for out-of-towners to see what Buffalo offers and a big help to the businesses there.

WN: Are you considering more time for the community to make a judgment?

Hassett: As I mentioned above, we expect to have one more meeting to get public reaction to the new design, and I think the Planning Board may want an additional meeting to make their determination. We do however, have constraints that will limit the amount of extra time. We still think it is a great project for the City and Elmwood; and we still want it to be something that the community wants as well.

So far, the City of Buffalo’s City Planning Board is still scheduled to meet at 8:00 a.m. (Eastern) on February 28, 2006 followed by the Common Council meeting at 2:00 p.m. on the same day.

Images of the design are not yet available. “We are working on the renderings this weekend, but I will likely have some early in the week,” stated Hassett.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

Friday, November 7, 2014Albuquerque, New Mexico —Online entertainment is a booming market, and plenty of players are making their play; back in March of this year The Walt Disney Company bought the multi-channel network Maker Studios. What is web entertainment, and the arts therein? And, who are the people venturing into this field? Wikinews interviewed Mario Lucero and Isabel Ruiz, the founders of Heaven Sent Gaming, a small entertainment team. This group has been responsible for several publications, within several different media formats; one successful example was aywv, a gaming news website, which was #1 in Gaming on YouTube in 2009, from September to November; Heaven Sent Gaming was also the subject of a referential book, released in 2014, entitled Internet Legends – Heaven Sent Gaming.
