Unlimited capacity in wireless networks with massive MIMO

Emil Bjornson, Linkoping University Massive MIMO is an antenna technology that is considered the most promising for future superfast 5G networks, although researchers have until now believed that there is an upper limit for how much data can be transferred. Emil Björnson, associate professor at Linköping University, has together with colleagues, shown that there is no such limit. “We can show that massive MIMO has unlimited capacity, both mathematically and with the aid of simulations,” says Emil Björnson, associate professor…

Fish’s skin senses light differently from eyes — ScienceDaily

Some animals are quick-change artists. Take the hogfish, a pointy-snouted reef fish that can go from pearly white to mottled brown to reddish in a matter of milliseconds as it adjusts to shifting conditions on the ocean floor. Scientists have long suspected that animals with quick-changing colors don’t just rely on their eyes to tune their appearance to their surroundings — they also sense light with their skin. But exactly how “skin vision” works remains a mystery. Now, genetic analysis…

Region Evacuation Reimagined – Netflix TechBlog – Medium

We are proud to present Nimble: the evolution of the Netflix failover architecture that makes region evacuation an order of magnitude faster. At Netflix, our goal is to be there for our customers whenever they want to come and watch their favorite shows. A lot of the work we do centers around making our systems ever more available, and averting or limiting customer-facing outages. One of the most important tools in our toolbox is to route traffic away from an…

Deprecating TLS 1.0 and 1.1 on api.cloudflare.com

On June 4, Cloudflare will be dropping support for TLS 1.0 and 1.1 on api.cloudflare.com. Additionally, the dashboard will be moved from www.cloudflare.com/a to dash.cloudflare.com and will require a browser that supports TLS 1.2 or higher. No changes will be made to customer traffic that is proxied through our network, though you may decide to enforce a minimum version for your own traffic. We will soon expose TLS analytics that indicate the percent of connections to your sites using TLS…

Lighter than Lightweight: How We Built the Same App Twice with Preact and Glimmer.js

Time in milliseconds; lower is better. SSR = Server-side rendered, CSR = Client-side rendered. Render time measured in CSR mode, rehydration time measured in SSR mode. Both flavors performed very well. The SSR variants in particular showed dramatic improvement in First Meaningful Paint, reducing the time before a member sees useful content by over one second compared to the CSR variants. Based on our test, Glimmer.js seemed to slightly outperform Preact at achieving First Meaningful Paint and Rehydrating/Rendering the page,…

Using pedometers in a short term walking program boosts long term activity — ScienceDaily

Experts have found that people who use pedometers to count their steps as part of a 12-week walking programme, can have a healthier, more active lifestyle three to four years later. Brisk walking for 30 minutes or more daily on most days of the week can help adults and older adults to achieve important health benefits. Researchers at St George’s, University of London, compared adults and older adults in two 12-week walking programmes who were using pedometers, with people who…

Scientific analysis of diamond impurities — known as inclusions — reveal naturally forming ice crystals and point to water-rich regions deep below the Earth’s crust — ScienceDaily

A UNLV scientist has discovered the first direct evidence that fluid water pockets may exist as far as 500 miles deep into the Earth’s mantle. Groundbreaking research by UNLV geoscientist Oliver Tschauner and colleagues found diamonds pushed up from the Earth’s interior had traces of unique crystallized water called Ice-VII. The study, “Ice-VII inclusions in Diamonds: Evidence for aqueous fluid in Earth’s deep Mantle,” was published Thursday in the journal Science. In the jewelry business, diamonds with impurities hold less…

Flat gallium joins roster of new 2-D materials — ScienceDaily

Scientists at Rice University and the Indian Institute of Science, Bangalore, have discovered a method to make atomically flat gallium that shows promise for nanoscale electronics. The Rice lab of materials scientist Pulickel Ajayan and colleagues in India created two-dimensional gallenene, a thin film of conductive material that is to gallium what graphene is to carbon. Extracted into a two-dimensional form, the novel material appears to have an affinity for binding with semiconductors like silicon and could make an efficient…

Quality assessment of 360 video view sessions | Engineering Blog | Facebook Code

At Facebook we’re continuously pushing the boundaries of 360 technology. We’ve pioneered ideas such as offset cubemaps, dynamic streaming, and content-dependent streaming. With every new technology, it’s important to be able to assess the quality of the immersive experience compared with previous approaches in terms of things like resolution, bitrate, or structural similarity. A reliable quality assessment (QA) workflow can provide consistent criteria for comparing 360 view sessions and help us make data-driven decisions about whether to adopt a new…
