Network Coverage. For a long time EE was well in the lead when it came to 4G coverage , but as you can see in the chart above all of the networks now have almost complete 4G population coverage. Its population coverage may be similar to rivals but its geographic coverage is probably greater. EE also leads for latency the time it takes for a network to respond to a request , though O2 and Vodafone are close there, with Three trailing. Ultimately all the networks are fast, but right now – thanks to its 4G speed and 5G coverage advantage – EE is the best network for speed. For a long time Three was the clear winner in this category, as it was the only major UK network to offer unlimited data. Now though, its rivals have all started matching it.

Federal government websites often end in. The site is secure. NIST researcher June Lau with a transmission electron microscope TEM that she and her colleagues retrofitted in order to make high-quality atom-scale movies. Researchers at the National Institute of Standards and Technology NIST and their collaborators have developed a way to retrofit the transmission electron microscope — a long-standing scientific workhorse for making crisp microscopic images — so that it can also create high-quality movies of super-fast processes at the atomic and molecular scale.
Compatible with electron microscopes old and new, the retrofit promises to enable fresh insights into everything from microscopic machines to next-generation computer chips and biological tissue by making this moviemaking capability more widely available to laboratories everywhere. She reports the first proof-of-concept operation of this retrofitted design with her colleagues in the journal Review of Scientific Instruments. The team designed the retrofit to be a cost-effective add-on to existing instruments.
A nearly year-old invention, the electron microscope remains an essential tool in many scientific laboratories. A popular version is known as the transmission electron microscope TEM , which fires electrons through a target sample to produce an image. Modern versions of the microscope can magnify objects by as much as 50 million times.
Op-ed: China has a big but brief chance right now to speed its way to global leadership
What once was an opaque policy, articulated by Chinese leader Deng Xiaoping, of ” hide your strength, bide your time, ” has now morphed into the transparent, if still unstated, approach by President Xi Jinping of “seizing the Covid moment” — before it closes. The virus first appeared to be a dramatic setback for China, given its role as the pathogen’s source and epicenter in January and February.
With China’s likely emergence now as the first major world economy to end lockdowns and regain growth, Covid now offers a once-in-a-century chance to accelerate the geopolitical shift in Beijing’s favor through and far beyond. That said, Chinese leaders are moving at a pace that reveals not only their ambitions but also their apprehensions that this historic moment could close as quickly as it opened. At the same time, Beijing is wrestling with the new burdens of global leadership: demands from debtor nations for relief, from developing nations for accountability, from Covid victims for reparations and from the global human rights campaigners for less repression and more transparency.
Milliseconds after the opening trade, buy and sell orders began zapping across the market’s servers with alarming speed. The trades were obviously unusual.
Researchers have made a breakthrough in the control of terahertz quantum cascade lasers, which could lead to the transmission of data at the rate of gigabits per second — around one thousand times quicker than a fast Ethernet operating at megabits a second. What distinguishes terahertz quantum cascade lasers from other lasers is the fact that they emit light in the terahertz range of the electromagnetic spectrum. They have applications in the field of spectroscopy where they are used in chemical analysis.
The lasers could also eventually provide ultra-fast, short-hop wireless links where large datasets have to be transferred across hospital campuses or between research facilities on universities — or in satellite communications. To be able to send data at these increased speeds, the lasers need to be modulated very rapidly: switching on and off or pulsing around billion times every second.
A research team from the University of Leeds and University of Nottingham believe they have found a way of delivering ultra- fast modulation, by combining the power of acoustic and light waves.

Alina Selyukh. Courtesy of Flightradar24 hide caption. Kubilay Kahveci’s flight was supposed to be in the air for more than six hours — an overnight voyage from New York City to London. But British Airways Flight made the trek in under five hours, setting a new record for the fastest subsonic commercial flight across the Atlantic Ocean. But it wasn’t too bad after all and I’m glad they brought us home safely because I initially booked a Virgin Atlantic flight that was cancelled due to Storm Ciara.
Propelled by strong winds, the Boeing at its fastest topped a ground speed of miles per hour, according to global flight-tracking service Flightradar British Airways confirmed that the flight took 4 hours, 56 minutes, beating the previous record by Norwegian , which flew from New York to London in 5 hours, 13 minutes. Severe storms around the United Kingdom have been causing lots of flight delays, cancellations and diversions. But the wind conditions made for very fast eastbound flights, a few of which on Sunday crossed the Atlantic under the five-hour mark.
Petchenik said the New York-London route has historically been used as a speed benchmark for trans-Atlantic air travel. By Petchenik’s estimate, the jet stream winds may have added roughly miles per hour to the airplane’s speed.
Too Fast to Fail: How High-Speed Trading Fuels Wall Street Disasters
February 24, Researchers in South Korea have developed a new optical communications technology that can transfer data at lightning speed. The new technology sends and receives twice as much data as conventional methods. It is expected to contribute to solving data traffic congestion in 5G networks. It would take about four seconds to transfer an ultra-high-definition 4K film which is about gigabytes.
The new technology significantly improved data transfer speed by adopting a four-stage high-order modulation method, which is PAM-4 modulation with direct detection.
This is really cool. I interpret the art as someone finally facing his demons. He tried to be passive and go around them for so long but inevitably he has to face.
At A. The trades were obviously unusual. Soon complex computer programs deployed by financial firms swooped in. They bought undervalued stocks as the unusual sales drove their prices down and sold overvalued ones as the purchases drove their prices up. The algorithms were making a killing, and human traders got in on the bounty too. Within minutes, a wave of urgent email alerts deluged top officials at the Securities and Exchange Commission.
Meanwhile, across the Hudson River, in the Jersey City offices of a midsize financial firm called Knight Capital , panic was setting in. And no one knew how to shut it down. At this rate, the firm would be insolvent within an hour. By then it was shortly after 10 a. In the four years since the collapse of Lehman Brothers drove the global financial system to the brink of oblivion, new technologies have changed Wall Street beyond recognition.
Stock exchanges can now execute trades in less than a half a millionth of a second—more than a million times faster than the human mind can make a decision. Financial firms deploy sophisticated algorithms to battle for fractions of a cent.
The delivery of the 1,bed Leishenshan Hospital began on Thursday. It will soon join the 1,bed Huoshenshan Hospital to treat patients in the current novel coronavirus outbreak at its epicenter Wuhan in central China. Speed matters as the virus is spreading. Wuhan alone had a cumulative 10, confirmed cases as of Wednesday. The sheer number of patients requiring quarantine and intensive care would overwhelm the healthcare system of any city in the world if such a highly contagious disease broke out.
