Compact solid-state pulsed power generators achieve shorter, more powerful pulses — ScienceDaily

Powerful picosecond generators are in demand in various fields of experimental electrophysics to produce ultrashort electron beams and X-ray pulses in vacuum diodes and to form runaway electron flows in gases.

They also have applications in high-power microwave electronics, but researchers are constantly striving to obtain shorter and more powerful pulses.

In Review of Scientific Instruments, by AIP Publishing, scientists showed compact solid-state pulse generators could generate electrical pulses of less than one-billionth of a second in duration and up to 50 billion watts in power.

“For comparison, the most powerful hydroelectric power plant in China has an output power of 22.5 billion watts,” said Sergei Rukin, one of the authors.

Improving picosecond generators and mastering higher peak power levels in the picosecond range sets the groundwork for new applications in the coming years.

“This also happened with the development of powerful nanoscecond pulsed devices during the last 60 years,”

Xiaomi Mi 10T Pro review: a seriously powerful Android smartphone

The Xiaomi Mi 10T Pro is another flagship-level phone from the Chinese manufacturer, as it looks to gain even more market share outside of its home country. It follows on from the superb Xiaomi Mi 9T Pro from last year, and fits alongside the other Mi 10 phones of 2020.

It’s not a terribly easy range to figure out – there are several different-but-similar Mi 10 phones to pick from, with and without the T attached (though the T denotes the newer models), and then there are the Note models to take into consideration as well…

It’s perhaps easier to look at the prices to understand where each phone sits in the Xiaomi Mi 10 range. This Mi 10T Pro hasn’t been given a UK price (or launch date) yet, but costs €599 in European markets – that works out at roughly £545, so mid-to-upper-range pricing.

That’s a very reasonable

Apple is revealing its next-generation iPhone Tuesday that is rumored to include 5G connectivity and boast squared-off edges – but new leaks provide more details of what many are calling the iPhone 12.

The smartphone is set to have a 30x zoom camera that is capable of focusing in on objects and people three times farther than previous models.

Previous leaks suggested there will be four models release during the ‘Hi, Speed’ event and the latest news to surface says pricing will range from $699 to $1,099, with pre-orders starting October 16.

The lineup includes an iPhone 12 Mini with a 5.4-inch display, which starts at $699, a 6.1-inch handset at $799, the Pro handset is set at $999 and the iPhone 12 Pro Max will cost $1,099.

AMD says RX 6000 Big Navi will be ‘by far the most powerful gaming GPU we have ever built’

AMD just announced its new Zen 3-powered Ryzen 5000 series CPUs, but CEO Lisa Su didn’t stop there, ending her presentation with a preview of AMD’s other big PC announcement: the company’s upcoming RX 6000 “Big Navi” GPUs, which it’s set to announce on October 28th.

While full details on the upcoming lineup of graphics cards won’t come until later in October, Su is setting expectations high, promising that the RX 6000 lineup offers “by far the most powerful gaming GPU we have ever built.”

Su also offered a brief preview of what to expect from the company’s top-of-the-line Ryzen 5000 CPUs working together with the new RX 6000 series GPUs, showing a short clip of Borderlands 3 running at 4K resolution at over 60fps at “Badass Quality,” along with benchmarks for Call of Duty: Modern Warfare (88fps for 4K gameplay at ultra settings) and Gears 5 (73fps for 4K

We’ve all seen that moment in a cop TV show where a detective is reviewing grainy, low-resolution security footage, spots a person of interest on the tape, and nonchalantly asks a CSI technician to “enhance that.” A few keyboard clicks later, and voila—they’ve got a perfect, clear picture of the suspect’s face. This, of course, does not work in the real world, as many film critics and people on the internet like to point out.


However, real-life scientists have recently developed a true “enhance” tool: one that improves the resolution and accuracy of powerful microscopes that are used to reveal insights into biology and medicine.

In a study published in Nature Methods, a multi-institutional team led by

The Technology 202: Here are seven takeaways from the House’s sweeping report concluding Silicon Valley is too powerful

(Amazon chief executive Jeff Bezos owns The Washington Post). 

The report could provide a regulatory blueprint for lawmakers who have significantly ramped up rhetoric criticizing the tech giants in recent years, but have yet to actually pass any laws that would significantly check the industry’s power. The report’s authors, all Democrats, hope it will be a turning point for how Washington approaches corporate consolidation.

Congress must revive its tradition of robust oversight over the antitrust laws and increased market concentration in our economy,” the report said. 

Here are our top seven takeaways after sifting through the nearly 450-page report:

1. It proposes some most sweeping revisions to antitrust law in decades.

The report proposes changing existing laws in ways that could have far-reaching effects throughout the entire economy. The report recommends:

  • New limits on companies operating in adjacent lines of business, which could impact how tech companies operate

By analyzing videos uploaded to social media, scientists have calculated the strength of the blast that devastated the city of Beirut in August, finding it to be among the biggest non-nuclear explosions in human history.

When a warehouse at the Port of Beirut in Lebanon exploded this past summer, it released the equivalent of 500 tons of TNT and possibly as much as 1.12 kilotons of TNT, according to new research published in the scientific journal Shock Waves. That’s somewhere between 3% and 7% of the yield produced by the atomic bomb detonated at Hiroshima, which packed a blast yield equal to 15 kilotons of TNT. Accordingly, the explosion in Beirut now ranks among the 10 biggest accidental non-nuclear explosions of all time.

Around 2,750 tons of ammonium nitrate stored at Beirut’s port

Alienware m15 R3 Review: A Quieter, Powerful Gaming Laptop

Alienware m15 R3

Thin and light gaming laptops are no longer a novelty, as practically every PC maker offers their own take on the category. Some of them don’t always stand-out from the crowd, however, and can push the envelope on thermals in ever-tighter chassis designs. That is most definitely not the case with Dell’s Alienware m15 R3 though, unless you want to compare it to last year’s Alienware m15 R2. At a passing glance, this year’s refresh looks just like last year’s model. That is not a bad thing, as the new m15 R3 is a head-turning laptop with some notable improvements to this newest iteration, including a revamped cooling solution.

Quite frankly, we are just fine with the overall physical design staying the same for another round. Dell had already given the m15 a complete facelift last year, ditching the gray digs and outdated aesthetic of the original model and dressing

Antitrust chair says Congress will need the people’s help to rein in powerful Big Tech companies

Rep. David Cicilline (D-RI) thinks antitrust regulation of Big Tech companies like Amazon, Apple, Facebook, and Google is going to be tough, and in order to pass meaningful reforms that rein in the power of Big Tech companies, Congress will need the help of the American people. Cicilline is chair of the antitrust subcommittee in Congress and spoke Sunday as part of a Yale University School of Law conference about antitrust ahead of the anticipated release of what Cicilline calls the most extensive antitrust law reform investigation by Congress in more than 50 years.

Identifying anticompetitive behavior by big companies is pretty easy, he said, but developing solutions and gathering the necessary political support for reform is the challenge.

“We’re going to have to combat companies that have an enormous stake in maintaining the status quo, which has been enormously profitable for them, and so this will be a big
