Films and TV programmes have long portrayed caveman as using grunts to communicate with one another. But a new study suggests that our ancient ancestors likely did not use sounds to communicate, and instead opted for hand gestures. Researchers from the University of Western Australia asked volunteers to attempt to describe words using only grunts or gestures. They found that gestures were far more effective in communicating meaning and were often similar between cultures. 'The universality of gesture means it is ideally suited to bootstrapping human communication among modern humans and therefore supports the hypothesis that gesture is the primary modality for language creation,' the researchers said in their study, published in Proceedings of the Royal Society B. Films and TV programmes have long portrayed caveman as using grunts to communicate with one another. Searching for a way to make your point?

On the occasion of the upcoming GTC, I had the opportunity of speaking with two very important people that work every day at innovating XR at NVIDIA: David Weinstein, Director of Virtual and Augmented Reality, and Gregory Jones, Director of Global Business Development/Product Management. I had an interesting chat with them about NVIDIA's vision for the future, they also clarified to me what NVIDIA Omniverse is, and when 5G cloud streaming can become reality. As a full disclaimer, this is a paid article that I'm writing for a recent collaboration I started with NVIDIA to help them promote GTC, NVIDIA's flagship event, that this year will be held online on March 21st-24nd. You know me well, so you know that if I accepted a similar collaboration it is only because NVIDIA guaranteed me that it could be valuable for you, my readers. And in fact, this post is so full of interesting information that it doesn't look like a paid one at all This collaboration also lets me offer you one special bonus: if you live in the EMEA area (Europe, Middle East, Africa), if you register for the GTC event using my referral code https://www.nvidia.com/gtc/?ncid The graphics card will be extracted from all those who used my referral to register and who then followed at least one session during the event (the keynote does not count and just registering is not enough). I have not millions of followers, so the odds of winning aren't bad: it can be worth trying You can discover more about the GTC and some of its cool XR sessions in the remainder of this article.

Odanga Madung found users were being paid to tweet disinformation on social media, to try and influence policies in the country. In response to Odanga's research - Twitter permanently suspended hundreds of accounts, but he's called on them to'address the problem' ahead of elections in Kenya this year. The Natural Museum say a new plant-eating dinosaur has been discovered in China. Fossils found of the Yuxisaurus dinosaur include parts of the skull, jaws, limbs and large numbers of armour spines and plates. Microsoft's Direct-Storage API used in the Xbox Series X to massively improve loading times is coming to PC games.

Fox News host gives his take Zelenskyy's latest idea and provides insight on the biolabs in Ukraine on'Tucker Carlson Tonight.' This is a rush transcript from "Tucker Carlson Tonight," March 14, 2022. This copy may not be in its final form and may be updated. Here is something we just saw. I wish we brought it to you earlier. Volodymyr Zelenskyy, the President of Ukraine, of course, gave an interview recently that didn't get enough attention in this country. Zelenskyy needless to say, is currently engaged in a desperate fight for his country, his government, his life, and he has been since the Russian military invaded Ukraine nearly three weeks ago. So you can assume there is not a lot Zelenskyy thinks about at this point, apart from getting the Russians off of Ukrainian soil. So last week, Zelenskyy floated the idea of accepting so-called Ukrainian neutrality, agreeing not to join NATO; in exchange for that, he will get a Russian withdrawal from Ukraine. Now, there is nothing inherently controversial about Zelenskyy's idea. Ukraine was not on the cusp of joining NATO, anyway. NATO officials have long said they don't want Ukraine to join. It is not clear whose interest would be served by Ukraine joining NATO. So if accepting the status quo, going with the way things already were and were always going to be, if doing that convinces Putin to stop killing Ukrainians, and spares Ukraine from total and complete destruction, maybe it's not a crazy idea, maybe Zelenskyy is onto something, he certainly thought about it a lot. Maybe we ought to congratulate Zelenskyy for acting wisely on behalf of the country he leads. This could be a win for him and for the entire world. Probably not a lot of American media outlets will describe it that way; however.

In the past years, Europe has been consolidating its AI ecosystems. Various countries, including Belgium, have developed their own strategy for AI governance, to finance their research organizations, support their startups and create future generations of AI developers. What is being done in other countries? What has been their approach in terms of national AI plans, scientific funding, and industry development plans? What are the different cultural perspectives on this technology?

This work explores the application of nonlinear oscillators coupled by electric field in water for collective tasks in underwater robotics. Such coupled oscillators operate in clear and colloidal (mud, bottom silt) water and represent a collective electrochemical sensor that is sensitive to global environmental parameters, geometry of common electric field and spatial dynamics of autonomous underwater vehicles (AUVs). Implemented in hardware and software, this approach can be used to create global awareness in the group of robots, which possess limited sensing and communication capabilities. Using oscillators from different AUVs enables extending the range limitations related to electric dipole of a single AUV. Applications of this technique are demonstrated for detecting the number of AUVs, distances between them, perception of dielectric objects, synchronization of behavior and discrimination between 'collective self' and 'collective non-self' through an 'electrical mirror'. These approaches have been implemented in several research projects with AUVs in fresh and salt water.

Move over, Spot, there's a new quadruped robot in town. Unveiled at last week's International Robot Exhibition in Tokyo, Bex is a four-legged robot that's inexplicably modeled after an Ibex, a species of wild goat that's native to parts of Eurasia and Africa. Bex came out of the company's Kaleido program, which has seen it work on bipedal robots since 2015. Partway through that project, Kawasaki's engineers decided to build a robot that could both move quickly across level ground and navigate tricky terrain. As you can see from the video spotted by Gizmodo, Bex features a set of wheels on its knees, allowing it to move faster on smooth surfaces than the glacial pace it plods along when walking.

Which is more important – understanding what happened to your business last week or understanding what's happening right now? Well, both can provide useful insights that you might be able to use to improve your customer experience, make better products and services, or create efficiencies in your business processes. But there's a strong argument to be made that nothing is as vital as understanding what's going on in the here-and-now. Real-time analytics is about capturing and acting on information as it happens – or as close as it's possible to get. This involves streaming data, which could come from cameras or sensors, or it could come from sales transactions, visitors to your website, GPS, beacons, the machines and devices that operate your business, or your social media audience.

Tensor completion is a fundamental tool for incomplete data analysis, where the goal is to predict missing entries from partial observations. However, existing methods often make the explicit or implicit assumption that the observed entries are noise-free to provide a theoretical guarantee of exact recovery of missing entries, which is quite restrictive in practice. To remedy such drawbacks, this paper proposes a novel noisy tensor completion model, which complements the incompetence of existing works in handling the degeneration of high-order and noisy observations. Specifically, the tensor ring nuclear norm (TRNN) and least-squares estimator are adopted to regularize the underlying tensor and the observed entries, respectively. In addition, a non-asymptotic upper bound of estimation error is provided to depict the statistical performance of the proposed estimator. Two efficient algorithms are developed to solve the optimization problem with convergence guarantee, one of which is specially tailored to handle large-scale tensors by replacing the minimization of TRNN of the original tensor equivalently with that of a much smaller one in a heterogeneous tensor decomposition framework. Experimental results on both synthetic and real-world data demonstrate the effectiveness and efficiency of the proposed model in recovering noisy incomplete tensor data compared with state-of-the-art tensor completion models.

We study two state-of-the-art solutions to the multi-agent pickup and delivery (MAPD) problem based on different principles -- multi-agent path-finding (MAPF) and multi-agent reinforcement learning (MARL). Specifically, a recent MAPF algorithm called conflict-based search (CBS) and a current MARL algorithm called shared experience actor-critic (SEAC) are studied. While the performance of these algorithms is measured using quite different metrics in their separate lines of work, we aim to benchmark these two methods comprehensively in a simulated warehouse automation environment.
