​New York, March 3 (IANS) US tech giant Microsoft will start shipping the "Mixed Reality" headset later this month in a bid to make Wndows 10 the most complete platform across the broadest range of devices. Mixed Reality (MR) is a combination of virtual and augmented reality to produce new environments and visualisations where physical and digital objects co-exist and interact in real time. "When we begin the phased rollout of the developer kits this month, the kits will include the Acer headset, along with documentation and access to Windows 10 Insider preview builds and the software development kit (SDK) to enable developers to build mixed reality applications," said Alex Kipman, Technical Fellow, Microsoft. Acer Windows Mixed Reality Development Edition headset include two high-resolution liquid crystal displays at 1440 x 1440 resolution, display refresh rate up to 90 Hz (native), built-in audio out and microphone support through 3.5mm jack, single cable with HDMI 2.0 (display) and USB 3.0 (data) for connectivity. Microsoft plans to bring mixed reality content to the Xbox One family of devices, including Project Scorpio, in 2018. To empower even more developers to create in mixed reality, we gave a "golden ticket" to game developers who attended our Windows Mixed Reality session at Game Developers Conference, and those developers will receive the Acer developer edition headset in the coming months, added Kipman.

New York, March 3 (IANS) The worldwide wearables market reached a new all-time high as shipments reached 33.9 million units in the fourth quarter of 2016, growing 16.9 per cent year over year, with Fitbit leading the way by shipping 6.5 million units, according to a new report. Shipments for the entire year grew 25 per cent as new vendors entered the market and previous champions refreshed their product lineups with Xiaomi and Apple taking second and third spots respectively, the report from the market research firm IDC said. "With the entrance of multiple new vendors with strengths in different industries, the wearables market is expected to maintain a positive outlook, though much of this growth is coming from vendor push rather than consumer demand," Jitesh Ubrani, Senior Research Analyst for IDC Mobile Device Trackers, said in a statemnet. The year came to a close with 102.4 million devices shipped. Early on, the market was bifurcated between smart wearables -- those capable of running third party apps -- and basic wearables, which lack this ability. In the past few months, two major platforms, WatchOS and Android Wear, have pivoted towards fitness and health applications. Fitbit maintained its dominance, holding the top position with 19.2 per cent of the market share in the fourth quarter. Xiaomi's growth helped to close the gap between it and Fitbit. The Chinese electronics major shipped 5.2 million units and took 15.2 per cent market share. Apple Watch Series 1 and Series 2 proved to be a magnificent success for the company as it was the company's best quarter ever in the wearables market with the company shipping 4.6 million units capturing 13.6 per cent market share. US-based Garmin experienced a slight decline of four per cent and shipped 2.1 million units capturing 6.2 per cent of market shar in the fourth quarter of 2016. Samsung rounded out the top five with the launch of two new models -- Gear S3 Classic and Frontier. It shipped 1.9 million units and had 5.6 per cent market share. Ear-worn devices (hearables) surpassed one per cent of all shipments for the first time in a quarter and sensor-laden clothing accounted for more than one per cent of the entire market for the full year 2016.

Dubai, March 3 (IANS) If Delhi Haat in India's capital fascinates you with its offerings from all parts of the country, this iconic family destination and entertainment adda for adults brings together snapshots of cultural extravaganzas from across the world in one massive open sky emporium here.

Global Village is the largest seasonal cultural extravaganza in the region that offers visitors an amazing array of festivals, shopping and entertainment in an open-air theme park.

This entertainment and shopping destination is open from November through to April and hosts over 70 participating countries presented in over 36 pavilions, with more than 50 fun rides and 26 restaurants offering food from around the world.

And still it is but a big surprise as it does not exist for half of the year. Every year, it is constructed from scratch around November and dismantled the following April. The makeover is different every year, new themes are introduced and thus, even those who visit regularly find it stunningly amazing.

Just like this city, Global Village comes from humble beginnings, starting out with just a number of kiosks in 1996 located on the Creek Side opposite the Dubai Municipality. It moved to another location before finally settling at its present location in Dubailand.

For some strange reason, the Indian pavilion catches your attention almost instantly. Not only because it is the largest pavilion at Global village but just as you enter the destination, a massive replica of the Taj Mahal sort of enchants you and prepares the mood for a visit.

While songs like "Kajra Re" and "Kal Ho Na Ho" are attracting Bollywood fans, it is the ethereal elements like the shenai and the traditional Indian bioscope, taking you on an all-India ride in just two minutes, that makes it memorable even for Indian visitors.

With more than 300 stalls, the Indian pavilion exhibits and sells some authentic Indian products varying from cotton, silk, chiffon fabrics to traditional leather made sandals, handbags, wallets and accessories. Indian carpet exhibitors are also present to express Indian forms and shapes of hand-woven natural silk and fleece, jewellry, cloths and home accessories.

Some 300 metres ahead is the Pakistani pavilion, no lesser attractive or magnificent than the Indian one.

It hosts a large number of exhibitors showcasing leather goods, cotton fabrics and various traditional items and home accessories. Its narrow lanes, dotted with tiny shops selling leather jackets, samosas or even jhaalmuri, seem straight out of some Lahori gali. 

This is not all. Adding to the many stories of friendships of Indians and Pakistanis abroad are a large number of sellers and shopkeepers from the two countries here. Many sellers shared their touching stories of friendships and said that Indians and Pakistanis are "too friendly to even argue, except for cricket".

The US and Russia relations may be anticipated to improve under the Trump administration but at the Global Village, the pavillions of Russia and the Americas co-eistand right next to each other.

The Americas' pavilion brings a wide range of interesting products that represent North, Central and South America. The facade is inspired by the Capitol building in Washington D.C. and the Cathedral in Mexico City.

The pavilion's rear facade depicts the Washington monument. The products and services offered within allow for a sampling of the lifestyles and tastes of the 48 countries in North and South America. The pavilion welcomes visitors to discover the culture and tradition of this culture rich region and experience live performances of various dance styles that originated in this part of the world.

Step out and enter the Russian pavilion. From the famous Onion Domes of Red Square to the Matryoshka dolls, Ladel spoons, Samovars and traditional Russian costumes, the whole package is too much to sum in a few words. Indulge in the rich culture of the former Soviet Union with all your senses.

Another interesting pavilion is from Africa, perhaps the most suitable if you are looking for some authentic stuff at a bargain.

The pavilion represents more than 15 countries, including Kenya, Uganda, Tanzania, Senegal, Ghana, Ethiopia, Mauritania, Angola, Zimbabwe, Sudan, Rwanda, Madagascar, Namibia, South Africa and Nigeria. Most of these countries showcase their authentic products as well as their art, wealth and traditions. The pavilion's prevalent offering is hand-carved artifacts. The intricate designs are made from the best type of wood in the world such as ebony, mahogany and rosewood, as well as soapstone.

What actually makes the Global Village appealing is its Bazar like design. From bargains to haunted houses, all things here seem a bigger and better replica of what the Indian circus melas once used to be.

Washington, March 2 (IANS) In a first, scientists have measured rapidly varying temperatures in hot gas emanating from around a black hole and found that the winds can heat up and cool down in the span of just a few hours.

The findings, published in the journal Nature, could shed new light on how winds emanating from around a black hole can affect the environment of host galaxies.

For the study, the researchers used data from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) telescope and the European Space Agency's XMM-Newton telescope. 

"We know that supermassive black holes affect the environment of their host galaxies, and powerful winds arising from near the black hole may be one means for them to do so," said NuSTAR Principal Investigator Fiona Harrison, Professor at California Institute of Technology in the US.

"The rapid variability, observed for the first time, is providing clues as to how these winds form and how much energy they may carry out into the galaxy," Harrison said.

The black hole that the researchers observed is located in the active galaxy IRAS 13224-3809 in the constellation Centaurus.

To measure the temperatures of these winds created by disks of matter surrounding black holes, the team studied X-rays coming from the edge of the black hole. 

As they travel toward Earth, these X-rays pass through the winds, and some wavelengths of the X-ray spectrum are absorbed by different elements in the winds, such as iron and magnesium. 

By examining the holes, or "absorption features", in the X-ray spectrum as it reaches Earth, astronomers can learn more about the components of the wind.

While observing this spectrum, the team noticed that the absorption features were disappearing and reappearing in the span of a few hours. 

The team concluded that the X-rays were actually heating up the winds to very high temperatures so that they became incapable of absorbing any more X-rays. 

The winds then cool off, and the absorption features return, starting the cycle over again.

"This is the first time we have seen that winds are interacting with the black hole's radiation," study first author Michael Parker, postdoctoral scholar at University of Cambridge Institute of Astronomy in Britain

​New York, March 3 (IANS) NASA scientists have demonstrated that a new space weather warning system could help astronomers detect harmful solar particles much before they leave the sun's inner atmosphere -- critical extra time that could help protect astronauts in space.

Solar energy particles (SEPs) can move at nearly the speed of light -- so their total travel time can be less than an hour from the time they are accelerated near the sun to when they reach Earth.

In the study published in the journal Space Weather, scientists from NASA and the US National Center for Atmospheric Research, or NCAR, in Boulder, Colorado, showed how ground-based instruments called coronagraphs can help lengthen the warning time for solar particles.

Earth's magnetic field and atmosphere protect us on the ground from most of the harmful effects of space weather, but astronauts in low-Earth orbit -- or even, one day, in interplanetary space -- are more exposed to space weather, including bursts of fast-moving particles called solar energetic particles, or SEPs.

"Robotic spacecraft are usually radiation-hardened to protect against these kinds of events," said lead author on the study Chris St. Cyr, a space scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. 

"But humans are still susceptible," Cyr said.

So NASA wants to help improve systems that would provide future astronauts with advance warning of incoming SEPs. 

In the recent paper, the scientists showed that tracking an associated kind of solar explosion -- fast-moving clouds of magnetic solar material, called coronal mass ejections -- can help.

Scientists observe coronal mass ejections using a type of instrument called a coronagraph, in which a solid disk blocks the sun's bright face, revealing the sun's tenuous atmosphere, called the corona. 

Space-based coronagraphs are more widely used in space weather research because of their wide-field solar views that are not interrupted by cloud cover or Earth's rotation. 

But the new study showed that ground-based coronagraphs could improve the warning system.

​London, March 3 (IANS) Researchers have developed a new algorithm to identify the origin of irregular electrical 'storm waves' in the heart, a finding with major implications for the future treatment of a killer cardiac disease.

Atrial Fibrillation -- one of the most common forms of abnormal heart rhythm -- is caused by these waves and is a major cause of stroke as it increases the risk of blood clots forming inside the heart.

Current methods involve the use of a catheter to isolate the storm waves. However, this is very invasive surgery and it is extremely difficult to identify the origin of the waves in order to treat the condition, said researchers from UK's University of Manchester.

In the study, published in ther journal PLOS Computational Biology, researchers used a virtual human heart-torso and a 64-lead electrocardiogram (ECG) vest to study the correlation between the origin of the storm waves and the features of the ECG signals.

Using the properties of the atrial activation and the signals, they were able to develop a novel algorithm which could pin down the location of Atrial Fibrillation non-invasively, as well identifying different types of the condition.

"This technique can identify the origin of Atrial Fibrillation extremely effectively, which may provide a powerful tool for treatment in the future," said lead author Henggui Zhang, Professor at University of Manchester.

"The research, could lead to new developments to tackle heart problems more effectively and simply," Zhang added.

Atrial tachy-arrhythmias, including atrial fibrillation (AF), atrial tachycardia (AT) and flutter (AFL), are the most common cardiac arrhythmias, predisposing to heart attack, stroke and even possible cardiac death. 

Atrial fibrillation presents the greatest complexity and occurs in about 1-2 per cent of people and studies have shown that it is on the rise in the developed world due to the ageing population.
