KUALA LUMPUR, Feb 22 (Bernama) -- National Tsing Hua University (NTHU) research team in Taiwan has captured an instant moment in the nanoworld by producing attosecond extreme ultraviolet pulses.

This light source can work as a nano camera to capture images of 5-nanometer-scale objects that move at an extremely high speed, such as an electron.

NTHU in a statement said this technology is expected to advance the design of next-generation transistors and memory chips with significantly increased speed for computers and communications.

Led by Associate Professor Ming-Chang Chen of the Department of Electrical Engineering and Associate Professor Ming-Wei Lin of the Institute of Nuclear Engineering and Science, the team is world’s first which developed a high-efficiency pulse compression technology for compressing a ytterbium-doped laser to 3,000 attoseconds.

When this light source was further focused into an inert gas, it produced extreme ultraviolet pulses with a duration of only 290 attoseconds.

Patents for this innovative technology have been applied for in the United States, Europe and Taiwan, and the team's research has been published by the top journal Science Advances.

With the goal of greatly reducing the pulse duration, the team focuses on developing a “spectrum broadening and pulse compression” technology by first stimulating more light waves of different frequencies in the space and then aligning the peaks of these new waves to superimpose them.

Repeating this process of spectral broadening and compression can subsequently shorten the pulse duration and increase the pulse peak.

The pulse duration can be compressed from 160,000 attoseconds to 290 attoseconds with a remarkable compression ratio of 550 via this technology.

KUALA LUMPUR, Feb 2 (Bernama) -- Wemade Co Ltd launched its mobile massively multiplayer online role-playing game (MMORPG) MIR M: Vanguard & Vagabond (MIR M) in more than 170 countries on Jan 31.

The South Korean online game developer said MIR M is a MMORPG that recreated ‘The Legend of Mir 2’, Wemade’s representative intellectual property that received a lot of attention from global players and led the craze for K-games.

“MIR M maximises the unique strategic performance of the original game with ‘grid battlegrounds’ that enhance the fun of tactical plays and 'quarter-views’ that allow users to easily identify the battle composition,” it said in a statement.

It also has a new growth system with a high degree of freedom called Mandala, which allows users to activate different states and customise characters in their own way. ‘Hidden Valley Capture’ and ‘Sabuk Castle Siege’ allow users to compete for economic rewards and power.

According to Wemade, the game token 'DRONE' and governance token 'DOGMA' have been added to MIR M to create an 'inter-game economy' with MIR4 and Non-Fungible Token trading service for game characters and items in the future will also be launched.

Wemade is planning numerous events to celebrate the official launch of MIR M by holding special events like Party Dungeons and Dungeon Raids, giving away various summon tickets and other items through daily check-in events, among others.

MIR M, which supports a total of 12 languages, can be downloaded from the Google Play Store, Apple App Store and the official website.
