MONITORING / Linking a brain implant to an AI to allow paralyzed people to express themselves is the challenge that a team of scientists from Stanford University decided to take up. Their device is able to convert simple thoughts into text and intelligible audio in record time.

If the experiments have only been carried out on one person for the moment, the results are already very positive, note the researchers in their study published at the end of January in the scientific journal bioRxiv. Indeed, the patient can now speak at a speed of 62 words per minute, thanks to the implant placed by the researchers, once morest a usual rate of regarding 160 words per minute.

The notable demand for solar energy has put Brazil on the map of investors and entrepreneurs. Privileged with a high incidence of solar radiation, the country might prove to be one of the leaders in what is one of the markets with the highest growth in recent years.

Solar energy has already brought more than R$ 120.8 billion in investments to Brazil, surpassing wind energy and becoming the second largest source of the Brazilian electricity matrix, according to data released by the National Electric Energy Agency (Aneel) and the Brazilian Association of Solar Energy (ABSOLAR) . According to Absolar, this market has already generated more than R$36.6 billion in revenue for the country and created more than 690,000 jobs.

Everything indicates that such growth will be further driven by the exemption that ended on January 6th, thus stimulating the installation of photovoltaic panels on residential roofs, buildings, companies and rural areas.

“The advancement of solar power in the country is fundamental for the social, economic and environmental development of Brazil. The technology helps to diversify the electrical matrix, increase supply security, reduce pressure on water resources and protect the population when the electricity bill is high”, explains Douglas Andrade, owner of the company Solar Power Photovoltaic.

The sector has more than 7 GW in centralized energy generation made up of large photovoltaic plants. This market represents approximately R$31.3 billion in investments and more than 212,000 accumulated jobs, in addition to offering collections of more than R$10.8 billion, according to Absolar.

The entrepreneur also warns of the need for the national government to update its public policies, thus avoiding the risk of missing the best timing of opportunities. “Those who have already been working in the market have seen demand grow month following month. Installations of solar panels on residential and commercial rooftops confirm forecasts for widespread growth. “Our country has one of the best “solar resources on the planet”, he points out.

However, there is still a lack of good public policies for us to aim for solar leadership worldwide”, says Andrade. For Brazil to become the sustainable power it craves, even appearing as a potential market leader, it will be necessary to invert the logic of the energy policies implemented in the national territory.

“It is necessary to reduce subsidies, incentives and exemptions for fossil sources and increase support for clean and renewable sources. It is in this direction that the world is heading and that is what Brazilian society and the international community expect from our leaders, that is, a state project aligned with a development that is already established as inevitable”, concludes the entrepreneur

Samsung’s latest-generation Galaxy S23 series models will use a custom Snapdragon 8 Gen 2 for Galaxy processor, and there will be no Exynos version. So how does this custom Snapdragon 8 Gen 2 for Galaxy processor perform?

First look at the public parameters. The Snapdragon 8 Gen 2 for Galaxy processor is equipped with 1 Cortex-X3+2 Cortex-A715+2 Cortex-A710 and 3 Cortex-A510 cores. Among them, the core clock frequency of Cortex-X3 is upgraded from 3.2GHz to 3.36GHz, and the frequency of Adreno 740 GPU is increased from 680 MHz to 719 MHz.

Recently, foreign media Gsmarena conducted a benchmark test on the Galaxy S23 Ultra. The Geekbench 5 CPU test results show that the Galaxy S23 Ultra lags behind the iPhone 14 Pro Max with the A16 processor in both multi-core and single-core scores. Compared with the Android lineup, the single-core test of the Galaxy S23 Ultra is ahead of the Red Magic 8 Pro, but the multi-core test lags behind the latter. According to Gsmarena’s analysis of running scores, the Galaxy S23 Ultra did not use the Cortex-X3 core in the multi-core test, which resulted in unsatisfactory multi-core running scores.

In the AnTuTu benchmark, the Galaxy S23 Ultra lags behind the Red Magic 8 Pro (8 Gen 2). This is because the Red Magic 8 Pro is a game console that actively cools down, and the screen is only 1080p+, which requires less graphics computing power. But fortunately, the Snapdragon 8 Gen 2 for Galaxy is much more powerful than the Snapdragon 8+ Gen 1 processor, and it even has an advantage over the A16 Bionic of the iPhone 14 Pro Max.

In scenarios involving GPU-intensive tasks, Snapdragon 8 Gen 2 for Galaxy performed well, almost leading other phones in the Offscreen test, but was slightly inferior in the Onscreen test due to the high screen resolution affecting the running score.

Combining the two benchmark tests, it is known that the CPU of the Galaxy S23 Ultra is 30-35% faster than the Galaxy S22 Ultra, and the AnTuTu 9 comprehensive benchmark test is regarding 30% faster. GFX Bench and 3DMark GPU tests can provide up to 2 times the performance improvement, and there will still be 80-90% improvement in most other scenarios.
