Water level decreases in Hirakud reservoir, 3 sluice gates closed

The award went to Pierre Agostini from the the Ohio State University; Ferenc Krausz from Max Planck Institute of Quantum Optics, Germany; and Anne L’Huillier from Lund University, Sweden “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”.

In the world of electrons, changes occur in a few tenths of an attosecond -- an attosecond is so short that there are as many in one second as there have been seconds since the birth of the universe.

The Laureates’ experiments have produced pulses of light so short that they are measured in attoseconds, thus demonstrating that these pulses can be used to provide images of processes inside atoms and molecules.

“The three Nobel Laureates in Physics 2023 are being recognised for their experiments, which have given humanity new tools for exploring the world of electrons inside atoms and molecules,” the Academy said in a statement.

“Pierre Agostini, Ferenc Krausz and Anne L’Huillier have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy”.

A prize money of 11 million Swedish kronor will be shared equally between the Laureates.

In 1987, L’Huillier discovered that many different overtones of light arose when she transmitted infrared laser light through a noble gas.

Each overtone is a light wave with a given number of cycles for each cycle in the laser light. They are caused by the laser light interacting with atoms in the gas; it gives some electrons extra energy that is then emitted as light.

L’Huillier has continued to explore this phenomenon, laying the ground for subsequent breakthroughs.

In 2001, Agostini succeeded in producing and investigating a series of consecutive light pulses, in which each pulse lasted just 250 attoseconds.

At the same time, Krausz was working with another type of experiment, one that made it possible to isolate a single light pulse that lasted 650 attoseconds.

The Laureates’ contributions have enabled the investigation of processes that are so rapid they were previously impossible to follow.

“We can now open the door to the world of electrons. Attosecond physics gives us the opportunity to understand mechanisms that are governed by electrons. The next step will be utilising them,” said Eva Olsson, Chair of the Nobel Committee for Physics.

There are potential applications in many different areas. In electronics, for example, it is important to understand and control how electrons behave in a material.

Attosecond pulses can also be used to identify different molecules, such as in medical diagnostics.

India is expected to export about 22 per cent of its total assembled mobile phones in 2023, according to Counterpoint Research.

However, China’s manufacturing and supply chain will still maintain its essential role in the longer run,” said senior research analyst Ivan Lam.

In a fillip to the ‘Make in India’ initiative, India saw mobile phones exports worth $5.5 billion (over Rs 45,000 crore) in the April-August period in the ongoing fiscal year (FY24), government and industry data showed recently.

As per the estimates by the Department of Commerce and the India Cellular and Electronics Association (ICEA), the April-August period saw mobile phone exports worth $5.5 billion, against $3 billion (about Rs 25,000 crore) in the same period in FY22-23.

India is set to cross Rs 1,20,000 crore in mobile phone exports in the current fiscal year, with Apple leading the market with more than 50 per cent in FY24.

Meanwhile, according to the report, smartphone shipments from original design manufacturers (ODMs) and Independent Design Houses (ODMs/IDHs) declined six per cent (year-on-year) in the first half this year, according to the report.

“The YoY decline in ODM/IDH companies’ H1 2023 shipments was driven by Samsung, Xiaomi and Lenovo Group’s weak performance. However, Vivo, HONOR and Transsion Group’s rise offset part of the decline,” said senior research analyst Shenghao Bai.

Huaqin, Longcheer and Wingtech continued to dominate the competitive landscape of the global smartphone ODM/IDH industry in H1 2023.

The companies, also known as the ‘Big 3,’ accounted for 76 per cent of the global ODM/IDH smartphone market in the first half. Outsourced design shipments decreased in H1 2023 but their share increased when compared to the same period last year, the report mentioned. The top six ODMs took 95 per cent share of the total ODM shipments. (IANS)

Musk on Monday posted a video on X, saying:"Tested the X video game streamer system last night. It works! Will try to complete a Tier 100 Nightmare dungeon tonight live on this platform."

After a few hours, he streamed the Nightmare dungeon game on X in an almost 40-minute-long video.

"Testing video game streaming on X," Musk captioned the video.

Several users expressed their views on this development.

"Embarking on a journey with X live game streaming! It's a whole new world of gaming, and I can't wait to share my experiences with all of you. Expect some action-packed gaming sessions and interactive fun," a user wrote.

"This is gonna be my new favourite way to watch streams," another user said.

Separately, the company announced a new partnership with socialite Paris Hilton and her 11:11 Media company to begin experimenting with live shopping features.

According to Variety, Hilton has signed on to "create four original video content programs per year that include live-shopping features".

“I’m excited to announce an official partnership with X today,” Hilton, chairwoman and CEO of 11:11, said in an audio post on the service.

“Together, we’re going to be exploring new ways to connect with all of you across video, live video, live shopping and even Spaces. And we’re just getting started. Loves it,” she added.

Users will be able to watch, chat, and shop in the same window with X's live shopping product.

Users will be able to browse a catalogue of products while watching a livestream with Hilton on X and then click through to the site to make a purchase using the service's in-app browser.

Linda Yaccarino, CEO of X, posted:“The queen of pop culture, music, business, and TV is #Sliving on X. @ParisHilton welcome to the @X family, we’re excited to launch an official partnership with you and your next-gen media company 11:11.” (IANS)
