Neural networks biological and artificial.

Neural Networks have found applications across various domains due to their ability to learn from data and improve over time without human intervention. They can solve challenging problems that are hard or impossible to solve using traditional methods. Here are some of the examples of how neural networks and artificial neurons are used in real-world scenarios:

Voice assistants: Voice assistants like Siri and Alexa use neural networks to understand spoken language commands and questions. They use trained models based on artificial neurons processing vast datasets of speech and text data. They can also generate natural-sounding responses and perform various tasks, such as playing music, setting reminders, searching the web, etc.

Self-driving cars: Self-driving cars use neural networks to perceive the environment and make decisions. They use trained models based on artificial neurons processing vast datasets of images, videos, and sensor data. They can also learn from their own experiences and improve their driving skills over time.

In an era where the internet connects virtually every aspect of our lives, the security of information systems has become paramount. Safeguarding critical databases containing private and commercial information presents a formidable challenge, driving researchers to explore advanced encryption techniques for enhanced protection.

Data encryption, a cornerstone of modern practices, transforms readable plaintext into encoded ciphertext, ensuring that only authorized recipients can decipher the data using a decryption key or password. Optical techniques have emerged as promising tools for encryption due to their capabilities for parallel, high-speed transmission, and low-power consumption. However, traditional optical encryption systems often suffer from vulnerabilities where plaintext-ciphertext forms remain identical, potentially compromising security.

Reporting in Advanced Photonics Nexus, scientists have unveiled an approach inspired by bio-inspired neuromorphic imaging and speckle correlography. Their innovative technique leverages computational neuromorphic imaging (CNI) to encrypt images into event-stream ciphertexts, marking a significant departure from conventional methods. This method introduces a new paradigm in optical encryption by converting data into event-driven formats, thereby significantly enhancing security and complexity.

What is the nature of quantum physics? Neil deGrasse Tyson and comedian Chuck Nice get quantum, exploring Schrodinger’s Cat, electrons, Hilbert Space, and the biggest ideas in the universe (in the smallest particles) with theoretical physicist Sean Carroll.

When did the idea of fields originate? Are fields even real or are they just mathematically convenient? We explore electrons, whether they are a field, and whether they exist at all. We also discuss the wave function, Hilbert Space, and what quantum mechanics really is. Do superpositions always exist?

What would happen if Planck’s Constant were macroscopic? Learn about entangling particles and the longest entanglement distances. If the particles are entangled why would the distance matter? Could we make an internet with quantum entanglement? We break down Schrodinger’s cat, its interpretations, and what the thought experiment really means. Do superpositions always exist?

Are there quantum manifestations in the macro-universe? We explore the microwave background, inflation, and how we discovered that atoms are mostly empty. Sean gives his latest takes on dark matter, dark energy, emergence, and free will. Plus, is dark energy really the cosmological constant?

According to the Speedtest Global Index, Australia ranks 64th in the world for fixed broadband speeds making it the slowest internet connected developed country with an average download speed of 46.24 Mbps. New Zealand ranks slightly higher at 50th, with an average download speed of 73.87 Mbps.

The Akamai State of the Internet Report says Australia’s internet connection speeds are now slower than 50 other nations, including Thailand, Estonia, Bulgaria and Kenya.

Aston University researchers and their international team have set a new data transmission record of 402 terabits per second using standard optical fiber, potentially stabilizing broadband costs as demand surges.

Researchers at Aston University, collaborating with a team, have achieved a new record by transmitting data at a rate of 402 terabits per second through commercially available optical fiber. This accomplishment surpasses their prior record set in March 2024, where they managed to send data at 301 terabits per second, equivalent to 301,000,000 megabits per second, using a single standard optical fiber.

According to the researchers, “If compared to the internet connection speed recommendations of Netflix, of 3 Mbit/s or higher, for watching an HD movie, this speed is over 100 million times faster.”

AI will enable drone wingmen to make autonomous decisions without centralized command.

According to Airbus, FCAS will be centered around a core Next Generation Weapon System (NGWS). In this “system of systems,” piloted New Generation Fighters will work together with Unmanned Remote Carriers – all connected to other systems in space, in the air, on the ground, at sea and in cyberspace via a data cloud called the “Combat Cloud.”

The FCAS is one more step towards the goal of achieving full collaborative combat by 2040, which can replace military systems like Rafale and Eurofighter.

Airbus says that an incremental roll-out of FCAS capabilities is planned by implementing initial situational awareness across platform capabilities in the mid-2020s.

The proposed innovative design leads to unprecedented power conversion efficiency and improved versatility. A recently developed wirelessly powered 5G relay could accelerate the development of smart factories, report scientists from Tokyo Tech. By adopting a lower operating frequency for wireless power transfer, the proposed relay design solves many of the current limitations, including range and efficiency. In turn, this allows for a more versatile and widespread arrangement of sensors and transceivers in industrial settings.

One of the hallmarks of the Information Age is the transformation of industries towards a greater flow of information. This can be readily seen in high-tech factories and warehouses, where wireless sensors and transceivers are installed in robots, production machinery, and automatic vehicles. In many cases, 5G networks are used to orchestrate operations and communications between these devices.

To avoid relying on cumbersome wired power sources, sensors and transceivers can be energized remotely via wireless power transfer (WPT). However, one problem with conventional WPT designs is that they operate at 24 GHz. At such high frequencies, transmission beams must be extremely narrow to avoid energy losses. Moreover, power can only be transmitted if there is a clear line of sight between the WPT system and the target device. Since 5G relays are often used to extend the range of 5G base stations, WPT needs to reach even further, which is yet another challenge for 24 GHz systems.
