Apple Connects World Maps to Its Ecosystem

Published

Apple has expanded the integration of the Mir payment system with its ecosystem.

Now Apple users can make payments with Mir cards in Apple services, for example, pay for apps in the App Store, Apple Music and Apple TV subscriptions, and so on.

Users noticed the expansion of the options in the “Payment Methods” section on the iPhone – the “World” card appeared in them. Previously, users could link Visa, Mastercard and American Express bank cards to their Apple account.

Recall that this is not the first step towards rapprochement between Apple and the National Payment Card System (NSPK). In July, it was announced that Mir cards were connected to the Apple Pay payment system – for contactless payments for travel, purchases in stores, and the like.

Asus PL63 mini PC features Thunderbolt 4 port

Published

on

The Asus catalog has replenished the PL63 mini-PC. According to the source, this is the first Asus mini PC equipped with a Thunderbolt 4 port. To clarify, only some configurations have such a port, while USB 3.2 takes its place in others.

The PL63 is powered by the 11th generation Intel Core mobile processor. Three options are available: Core i3-1115G4, Core i5-1135G7 and Core i7-1165G7. All of them are equipped with integrated Iris Xe GPUs.

The mini PC supports two SO-DIMMs and a PCIe 3.0 SSD. The PL63 is equipped with a 2.5 GbE port and HDMI 2.0 and DP 1.4 video outputs. Video can be output via two USB-C ports. Wi-Fi antennas are also visible in the illustrations. The kit includes an external power supply 19 V with a power of 90 W. The dimensions of the mini PC are 166.2 x 119.7 x 33.9mm.

Prices start at $508. That’s the price of a mini PC with an Intel Core i5-1135G7 processor, but it’s not clear if it’s a Thunderbolt 4 or USB 3.2 variant.

Global PC Shipments Up 3.1% in Q4 2021

Published

on

Analyst firm Counterpoint Technology has calculated that global PC shipments in the fourth quarter of 2021 reached 90.3 million units. Growth in annual terms amounted to 3.1%. This is a good indicator, given the high base in the fourth quarter of 2020. Analysts note that the situation with the supply of components and logistics continued to improve, albeit at a slow pace. The outlook for the first quarter of 2022 remains optimistic, mainly due to strong demand and an improvement in the situation with components.

Lenovo remains the market leader. For the year, it reduced shipments by 3%, from 22.4 to 21.7 million PCs. At the end of the quarter, Lenovo occupies 24.0% of the market. The share of HP is 20.5%. This manufacturer slightly increased supplies – from 18.4 to 18.5 million units. The Dell company increased deliveries by 15%, from 14.9 to 17.2 million pieces. It ranks third among PC manufacturers with 19.0%. Fourth-place Apple cut shipments by 1% from 7.3 million to 7.2 million. Apple’s share is 8.0%.

Some volcanic points have a shallow heat source

Published

on

The major part of volcanic activities of the Earth come from the tectonic plates of the earth’s crust. To do this, different materials from the depths come into fusion. They then rise to the surface. This is particularly the case for the hottest spots. However, all volcanic points do not come from deep mantles. In fact, some geological mechanisms are close to the Earth’s surface.

Volcanic eruption

The hot spots the coldest are fed by a fusion of materials far from the earth’s crusts. This is the result of a study conducted by Xiyuan Bao, a geophysicist at UCLA. It was published in the American journal Science.

This volcanic activity unusual is found in various regions of the globe. One can quote as examples the volcanoes of the islands of Hawaii, that of the Ascension in the South Atlantic or those of the Pitcairn Islands of the South Pacific.

Where do volcanoes come from?

A classic theory dominates the scientific world regarding volcanoes. It was the only known theory until this recent study. According to her, there is only one type of volcano. The latter comes from the plume of materials in the tectonic plates. The process begins with the convergence of the different materials. The mantle of the planet then allows them a wide circulation.

This is the dominant type. Their degrees of heat are quite high, as they are fed by the deep layers of the mantle.

The second type of volcano comes in the form of hot spots. This is the hypothesis of the UCLA scientists. Unlike the first, their intraplates are isolated. This is why their heats vary according to their depths. The study therefore concluded that some volcanic points have a lower temperature than others.

Heat buildup in the crust could then lead to local melting of carbonate-rich rocks that could fuel volcanism. »

A game-changing study

In order to conduct their studies, they traveled to ocean areas. First, they delimited their objects of study. In total, 26 volcanic points have been counted. Besides, scientists started with the hypothesis of their new theories. Indeed, they considered from the start that some of these volcanic points were fed by shallow material. As a result, their heat levels did not match normal.

To do this, seismic data were used to compare the different temperature levels. In order to obtain this data, they conducted the study on different depth scales. The distance examined underground varied from 260km to 600km. Thus, the results turned out to be positive.

First, 12 hotspots exhibited a temperature of 1388° Celsius or 2530° Fahrenheit. Next, 10 more hotspots had a lower temperature than the first ones. However, the study showed that they were 50° C and 135° hotter than certain volcanic points. In final, 4 volcanic points present 36° C less than the previous category.

“This study helps to determine which volcanic plumes are deep and which are not. »
