Voters’ choice: on Maldives presidential polls

The Maldives turns the page on pre-election cynicism with a dramatic result

he interim results of Sunday’s presidential election in the Maldives have given the joint opposition candidate, Ibrahim Mohamed Solih a resounding victory in the direct contest with the incumbent, Abdulla Yameen. The final results will be published by the election commission by September 30 and the current government will, according to procedure, hand over charge on November 17. But it is immediately clear that Maldivian voters have ushered in change, with 58% of the voters choosing Mr. Solih. Regardless of political affiliation, Maldivians have much to celebrate with the successful completion of the election. To begin with, the turnout of 89.2% has disproved pre-election cynicism about the integrity of the electoral process. Early on, the opposition had suffered a setback when former President Mohammed Nasheed, who was seen as the frontrunner, was disqualified from contesting because of a “terrorism conviction”. Former President Maumoon Abdul Gayoom was behind bars on the charge of attempting a coup in February this year. Just ahead of the elections too, there had also been many misgivings over the conduct of the election commission, the courts and security forces, with these worries heightened when the headquarters of the main opposition party, the Maldivian Democratic Party, to which Mr. Solih belongs, were raided. Counting procedures were changed at the last minute, which led to some confusion during Sunday’s polling, and many foreign journalists, including from India, were denied visas. Fortunately, the outcome has belied the worst fears about the election, and after meeting with Mr. Solih, President Yameen conceded defeat and vowed to ensure a smooth transition.

For New Delhi, the results are especially heartening as they present a chance to reset ties with Male, which have been on a downward spiral for several years. This was perceived to be a result of Mr. Yameen’s close understanding with China, to which the Maldives is now heavily indebted. Mr. Yameen responded to India’s criticism of the emergency he declared this year by clamping down on visas to Indian job holders, hundreds of whom await some movement in the matter after the new government takes over. India can also now renew talks over the fate of Indian Coast Guard and Air Force personnel stationed in the Maldives, whose visas have been pending since June. India was quick to welcome the provisional results and to congratulate, among others, the Maldivian Democratic Party, and the Jumhooree Party — to which the Vice-President-elect Faisal Naseem belongs. Going forward, New Delhi must stay clear of partisan positioning on the internal politics of the Maldives. The larger agenda must be to partner the Maldives in its stability and development rather than engaging in a tug of war with China.

After Salzburg: on rejection of post-Brexit blueprint

he rejection of Prime Minister Theresa May’s post-Brexit blueprint at the Salzburg summit rules out nothing as yet in Britain’s rocky negotiations on withdrawing from the European Union. All the same, the development is a blow to Ms. May, who faces a possible backlash at the Conservative party conference this month. Her proposal, adopted by the Cabinet in July, has deepened divisions among the Tories. Two senior Eurosceptic ministers have quit. A controversial idea in the July white paper is for a hybrid arrangement, with Britain staying in the common market only for trade in goods and agriculture, and without the obligations of free movement of people. This is at odds with the EU stance of not allowing cherry-picking when it comes to its four basic freedoms — of movement of capital, goods, services, and labour. The other dispute is over the post-Brexit status of the soft border between Northern Ireland and the Republic of Ireland. Maintaining the status quo is critical to keeping the peace under the terms of the 1998 Good Friday agreement. Brussels seems flexible on its original proposal for full regulatory convergence and jurisdiction of EU courts over Belfast. This is meant to assuage London’s concerns about two separate jurisdictions operating within the U.K. Britain’s alternative proposal to avoid the return of checkpoints on the Irish border and to get around the difficulties of erecting invisible borders is to bring all of the U.K. under a common customs arrangement. Eurosceptics see this as aligning the country too close to the EU and curbing its freedom to negotiate trade deals outside the bloc. For Brussels, it would still amount to an unacceptable division of the EU’s four freedoms.

European Council President Donald Tusk’s remarks in Salzburg that the July proposals were not workable amplified these concerns. They drew angry reactions from Ms. May, who harked back to the mantra that a no-deal was better than a bad deal. But then, discrepancies in the opposing positions go back to the 2016 referendum outcome. Brussels had said then that while it regretted the verdict, it respected London’s decision to leave. It stuck firm on established procedure and stressed that withdrawal negotiations could not commence until Article 50 of the EU treaty was triggered. It emphasised that exit from the bloc would involve costs for Britain, just as the benefits of membership entailed obligations. This accent on process could harden in the wake of the populist threat across the region to the European project. With elections to the European Parliament due next May, the leaders are keen that the anti-EU parties see the economic and political perils of quitting the bloc. Brexit uncertainty will linger, meanwhile.

Celestial misfit

We should accept Pluto as a dwarf planet, though an exceptional one

fter years of arguing over whether Pluto is a planet, in 2006 the International Astronomical Union (IAU) voted to remove Pluto’s planetary status. Now some researchers are challenging this decision, citing the manner in which scientific tradition has dealt with the taxonomy of planets. The IAU, in 2006, designated Pluto a ‘dwarf planet’ along with Ceres in the asteroid belt and Xena, an object in the Kuiper belt, which is an icy ring of frozen objects that circle the solar system beyond Neptune’s orbit. It was a bid to overcome sentiment and go by scientific rationale. The meeting defined three conditions for a celestial object to be called a planet: one, it must orbit the Sun; two, it should be massive enough to acquire an approximately spherical shape; three, it has to ‘clear its orbit’, that is, be the object that exerts the maximum gravitational pull within its orbit. Owing to this third property, if an object ventures close to a planet’s orbit, it will either collide with it and be accreted, or be ejected out. However, Pluto is affected by Neptune’s gravity. It also shares its orbit with the frozen objects in the Kuiper belt. Based on this, the IAU deemed that Pluto did not ‘clear its orbit’. Dwarf planets, on the other hand, need only satisfy the first two conditions.

This rationale has been questioned by Philip Metzger, a planetary physicist who has worked with the U.S. National Aeronautics and Space Administration, and others who have studied the history of classifying planets and come up with several exceptions to the third rule. In a paper published in the journal Icarus, they point out that the only work in history that used this rule to classify planets was an article by William Herschel in 1802. They also argue that this work was based on reasoning and observations that have since been disproved. However, the last argument does not build up a strong enough case to give up what is, in fact, a sensible rule. Physics has many examples where an idea was once discarded for being incorrect, and much later emerged in a different form and gained acceptance — the concept of photons, for instance. And then again, if Pluto were to be re-designated a planet, many more complications would arise. For one thing, Charon, Pluto’s moon, is much too large to be called a satellite. Judging by this, the Charon-Pluto system should then rightly be called a binary planet system. This would then lead to classifying several other sets of bodies as binary planets. Recent research shows that both the Kuiper Belt and the Oort cloud, a shell of objects that surrounds the entire solar system far beyond the Kuiper belt, contain objects that can then be called planets, thereby complicating the issue. Denying planetary status to Pluto is then nothing less than a sweep of Occam’s razor, and Pluto remains a dwarf planet, albeit an exceptional one.

Banking on mergers

sking healthy banks to take over weak banks appears to be the strategy to handle the bad loans crisis. On Monday the Union government proposed the merger of three public sector banks — Bank of Baroda, Dena Bank and Vijaya Bank — to create an amalgamated entity that will become the country’s third largest lender. The merger is part of the government’s efforts to consolidate the banking industry with an eye on overcoming the bad loan crisis. After the announcement of the merger, shares of Bank of Baroda and Vijaya Bank shed a significant part of their value, while Dena Bank gained sharply to hit upper circuit on Tuesday. This is not surprising at all. Dena Bank is the bank in the worst financial situation among the three entities and is currently under the Reserve Bank of India’s prompt corrective action framework. Unlike the other two banks, its shareholders are set to gain from being part of a new bank with greater financial strength. The current merger, it is worth noting, comes after the government let State Bank of India’s associate banks merge with their parent last year and the Life Insurance Corporation of India take over the troubled IDBI Bank this year.


Forced mergers such as the current one make little business sense for the stronger banks as the weaker banks tend to be a drag on their operations. They are also unlikely to solve the bad loan crisis that has gripped the banking system as a whole. It is important to ensure that such mergers do not end up creating an entity that is weaker than the original pre-merger strong bank. That said, the fact is that mergers are one way of managing the problem and therefore cannot be discounted totally. However, the trick lies in ensuring that the merger fallout is managed prudently; identifying synergies and exploiting scale efficiencies will be crucial here. There is no denying the fact that there are too many public sector banks in India; given this, consolidation is a good idea in principle. But ideally, mergers ought to be between strong banks. Then again, these are not normal times and with many banks in a precarious situation, the immediate compulsions for merging the weak Dena Bank with the stronger Bank of Baroda and Vijaya Bank are clear. From a corporate governance perspective, however, the merger sends out rather poor signals. Here is a dominant shareholder in the form of the government that is dictating critical moves that impact the minority shareholders, who are left with no say in the matter. A merger as significant as this one ought to have been first discussed and approved in the board rooms of the banks concerned. If the shareholders of Bank of Baroda, whose share fell by 16% on Tuesday, feel unhappy, that is perfectly understandable.

uDiamond Filament Improves Print Speed With Nanodiamonds

Helsinki-based Carbodeon are no strangers to nanodiamond filaments. The company has previously shown how the presence of nanodiamonds within thermoplastic filament can improve thermal conductivity and tensile strength, among other properties. Now, they’re back with a new uDiamond filament with the help of VTT, who helped test and develop the nanodiamond properties.

Nanodiamonds are spherical inserts that act as lubricant in the extrusion process. They don’t increase in nozzle wear and further improve various material characteristics. The diamond particles also reinforce the polymer structure, improving the stiffness, strength and adhesion between printed layers. Carbodeon has extensive patent coverage for the nanodiamond materials that it manufactures along with refined products enhanced with nanodiamonds.

Carbodeon’s uDiamond PLA is a high-performance diamond-enhanced 3D printing filament that even works with consumer-grade printers. It contains functionalised nanodiamond particles. The thermal conductivity in uDiamond enables printing speeds of up to 500mm/s. The filament is for both consumer-grade and professional FDM/FFF 3D printers. The recommended printing temperature is 220°C – 250°C (depending on the printing speed) which can be 50-500 mm/sec. Similarly, bed temperatures should range between 0°C – 50°C.

This is the first product of a family that will be sold as a finished 3D filament and in a granular format, as well. VTT has been a long-term, reliable partner in this development, and has reacted to our needs quickly,” said Carbodeon CEO Vesa Myllymäki.

VTT helped in developing methods for evenly dispersing the nanodiamonds in PLA to best optimise the filament specifically for printing. The diamond nanoparticles within uDiamond have a diameter of 4–6 mm. They aid in improving the thermal conductivity which, in turn, improves the smoothness of printing and processing. VTT´s Polymer Pilot produced the original 600 kg material batch, which Carbodeon had refined into a commercial product.

“Using our chemical pilot devices, we at VTT produced the nanodispersed material required for the melt processing, and thus supported the creation of a new product,” says Jarmo Ropponen, Research Team Leader at VTT’s chemical pilots.

Nanodiamonds significantly improve material performance at a low cost despite such small quantities being present. VTT state that the preliminary tests showed the modulus of the 3D-printed test pieces improved by over 200% in comparison with the standard, market PLA filament.

Physics Nobel won for invention of blue LEDs

It may be going too far to say this year’s Nobel prize in physics will save the world – but it will certainly make it more efficient.

The prize has gone to three semiconductor physicists who invented the blue LED (light emitting diode). Their invention has transformed the way we light our world, watch movies and store data.

Isamu Akasaki and Hiroshi Amano at Nagoya University in Japan, and Shuji Nakamura at the University of California in Santa Barbara, share the prize of 8 million Swedish kronor (£0.7 million).

LEDs as we know them were invented in the late 1950s, but only came in one colour: red. Green followed later, but although both were fine for indicator lights and digital watches, researchers really wanted a white LED. These are replacing traditional incandescent bulbs, which lose much of their energy as heat.

“Lighting currently consumes 20 per cent of all electricity,” says Colin Humphreys at the University of Cambridge. “Switching to LEDs could save 50 per cent, or over £2 billion in the UK alone.”

Colour addition

The key to producing white light was to make a blue LED and shine its light through a thin layer of yellow-emitting phosphor. This combination of yellow and blue makes white light much more efficiently than incandescent bulbs.

But blue LEDs had stymied researchers until the Nobel trio made their breakthrough in the late 1980s. The reason is to do with the way the devices are made. LEDs are made from multiple layers of semiconductor sandwiched together, one with an excess of electrons and the next with an excess of positively charged holes. Applying a voltage to the device drives the electrons and holes together into the “filling layer”, where they combine to emit light. The colour of this light depends on the semiconductor material. Red LEDs, for example, are made from gallium arsenide crystals.

Researchers realised that gallium nitride with a smattering of indium had the perfect quantum properties to emit blue light. But no one was able to make a semiconductor sandwich with a gallium nitride filling. That’s because the crystal structure of the gallium nitride needs to match that of the surrounding layers to prevent defects from forming that wreck the light-emitting properties.

In 1986, Akasaki and Amano succeeded in finding a match. Their trick was to add an extra layer to the sandwich. They grew their gallium nitride on top of a sapphire covered with a layer of aluminium nitride. Meanwhile Nakamura found his own way to create a gallium nitride crystal by growing a thin layer at low temperatures, then subsequent layers at higher temperatures. Nakamura had to work on his idea in secret after bosses at the Japanese company he worked for, Nichia, stopped his research because of lack of progress. Nakamura later sued Nichia and won more than $7 million compensation.

Blu movies

The trio went on to turn their blue LEDs into blue lasers, found in Blu-ray players. Because the wavelength of blue light is shorter than that of red LEDs, the beam can be focused to a small spot. This lets you cram more information on to a disc and read it out, giving Blu-rays a better picture quality than regular DVDs.

As well as saving money, LED lights can reduce pressure on Earth’s resources. Lights made from LEDs last for 100,000 hours, 10 times longer than fluorescent lamps and 100 times longer than incandescent bulbs. “The electronic circuits that control them give out before the LED,” says Humphreys.

He predicts many more advances to come.

Smart lighting that adapts to its surroundings could reduce energy bills by another 5 per cent. And by changing the phosphor coating on a blue LED it should be possible to produce lighting that mimics sunlight, which plays a key role in the human body clock. “This could be the end of jet lag and could improve the health of shift workers, who have been shown to have a higher risk of cancer.”

Akasaki, Amano and Nakamura will receive their award at the Nobel ceremony in December.

MONSTER BLACK HOLE DISCOVERED AT COSMIC DAWN

The discovery of the brightest quasar in the early universe, powered by the most massive black hole yet known at that time presents a puzzle to researchers: How could something so massive and luminous form so early in the universe, only 900 million years after the Big Bang?

The discovery of this quasar, named SDSS J0100+2802, marks an important step in understanding how quasars, the most powerful objects in the universe, have evolved from the earliest epoch, only 900 million years after the Big Bang, which is thought to have happened 13.7 billion years ago. The quasar, with its central black hole mass of 12 billion solar masses and the luminosity of 420 trillion suns, is at a distance of 12.8 billion light-years from Earth.

The discovery of this ultraluminous quasar also presents a major puzzle to the theory of black hole growth at early universe, according to Xiaohui Fan, Regents’ Professor of Astronomy at the UA’s Steward Observatory, who co-authored the study.

The quasar dates from a time close to the end of an important cosmic event that astronomers referred to as the “epoch of reionization”: the cosmic dawn when light from the earliest generations of galaxies and quasars is thought to have ended the “cosmic dark ages” and transformed the universe into how we see it today.

Discovered in 1963, quasars are the most powerful objects beyond our Milky Way galaxy, beaming vast amounts of energy across space as the supermassive black hole in their center sucks in matter from its surroundings. Thanks to the new generation of digital sky surveys, astronomers have discovered more than 200,000 quasars, with ages ranging from 0.7 billion years after the Big Bang to today.

Shining with the equivalent of 420 trillion suns, the new quasar is seven times brighter than the most distant quasar known (which is 13 billion years away). It harbors a black hole with mass of 12 billion solar masses, proving it to be the most luminous quasar with the most massive black hole among all the known high redshift (very distant) quasars.

“By comparison, our own Milky Way galaxy has a black hole with a mass of only 4 million solar masses at its center; the black hole that powers this new quasar is 3,000 time heavier,” Fan said.

Feige Wang, a doctoral student from Peking University who is supervised jointly by Fan and Prof. Xue-Bing Wu at Peking University, the study’s lead author, initially spotted this quasar for further study.

“This quasar was first discovered by our 2.4-meter Lijiang Telescope in Yunnan, China, making it the only quasar ever discovered by a 2-meter telescope at such distance, and we’re very proud of it,” Wang said. “The ultraluminous nature of this quasar will allow us to make unprecedented measurements of the temperature, ionization state and metal content of the intergalactic medium at the epoch of reionization.”

Following the initial discovery, two telescopes in southern Arizona did the heavy lifting in determining the distance and mass of the black hole: the 8.4-meter Large Binocular Telescope, or LBT, on Mount Graham and the 6.5-meter Multiple Mirror Telescope, or MMT, on Mount Hopkins. Additional observations with the 6.5-meter Magellan Telescope in Las Campanas Observatory, Chile, and the 8.2-meter Gemini North Telescope in Mauna Kea, Hawaii, confirmed the results.

“This quasar is very unique,” said Xue-Bing Wu, a professor of the Department of Astronomy, School of Physics at Peking University and the associate director of the Kavli Institute of Astronomy and Astrophysics. “Just like the brightest lighthouse in the distant universe, its glowing light will help us to probe more about the early universe.”

Wu leads a team that has developed a method to effectively select quasars in the distant universe based on optical and near-infrared photometric data, in particular using data from the Sloan Digital Sky Survey and NASA’s Wide-Field Infrared Explorer, or WISE, satellite.

“This is a great accomplishment for the LBT,” said Fan, who chairs the LBT Scientific Advisory Committee and also discovered the previous record holders for the most massive black hole in the early universe, about a fourth of the size of the newly discovered object. “The especially sensitive optical and infrared spectrographs of the LBT provided the early assessment of both the distance of the quasars and the mass of the black hole at the quasar’s center.”

For Christian Veillet, director of the Large Binocular Telescope Observatory, or LBTO, this discovery demonstrates both the power of international collaborations and the benefit of using a variety of facilities spread throughout the world.

“This result is particularly gratifying for LBTO, which is well on its way to full nighttime operations,” Veillet said. “While in this case the authors used two different instruments in series, one for visible light spectroscopy and one for near-infrared imaging, LBTO will soon offer a pair of instruments that can be used simultaneously, effectively doubling the number of observations possible in clear skies and ultimately creating even more exciting science.”
