From the dynamical point of view, most cognitive phenomena are hierarchical, transient and sequential. Such cognitive spatio-temporal processes can be represented by a set of sequential metastable dynamical states together with their associatedions: The state is quasi-stationary close to one metastable state before a rapidion to another state. Hence, we postulate that metastable states are the central players in cognitive information processing. Based on the analogy of quasiparticles as elementary units in physics, we introduce here the quantum of cognitive information dynamics, which we term “cognon”. A cognon, or dynamical unit of thought, is represented by a robust finite chain of metastable neural states. Cognons can be organized at multiple hierarchical levels and coordinate complex cognitive information representations.

This month in 1,871, James Clerk demonstrated entropy with a thought experiment now known as’s Demon.

Growth of data eases the way to access the world but requires increasing amounts of energy to store and process. Neuromorphic electronics has emerged in the last decade, inspired by biological neurons and synapses, with in-memory computing ability, extenuating the ‘von Neumann bottleneck’ between the memory and processor and offering a promising solution to reduce the efforts both in data storage and processing, thanks to their multi-bit non-volatility, biology-emulated characteristics, and silicon compatibility. This work reviews the recent advances in emerging memristive devices for artificial neuron and synapse applications, including memory and data-processing ability: the physics and characteristics are discussed first, i.e., valence changing, electrochemical metallization, phase changing, interfaced-controlling, charge-trapping, ferroelectric tunnelling, and spin-transfer torquing. Next, we propose a universal benchmark for the artificial synapse and neuron devices on spiking energy consumption, standby power consumption, and spike timing. Based on the benchmark, we address the challenges, suggest the guidelines for intra-device and inter-device design, and provide an outlook for the neuromorphic applications of resistive switching-based artificial neuron and synapse devices.

All.edu emails in the USA 🇺🇸 will WIN!Is the universe twice as old as we thought?Current estimates suggest that the Big Bang occurred 13.8 billion years ago. But today, we’re joined by Rajendra Gupta, a luminary in the field of cosmology who claims that the universe is actually 26.7 billion years old. I’ve invited him on the show so he can make a case for his claims!Professor Gupta is a theoretical physicist currently teaching astrophysics to senior undergraduate and graduate students at the University of Ottawa. His research focuses on astrophysics, cosmology, general relativity, the dynamics of the universe under evolutionary physical constants beyond the standard model, CMB, JWST, BAO, Big Bang nucleosynthesis, the large-scale structure and formation of galaxies, dark matter, and dark energy. To say I am thrilled to have him on the show for the second time would be an understatement. So, without further ado, let’s jump right in! Key Takeaways:

Hausjärvi, FINLAND— A Chinese launch of the joint Sino-French SVOM mission to study Gamma-ray bursts early Saturday saw toxic rocket debris fall over a populated area.

A Long March 2C rocket lifted off from Xichang Satellite Launch Center at 3:00 a.m. Eastern (0700 UTC) June 22, sending the Space Variable Objects Monitor (SVOM) mission satellite into orbit.

The launch was declared successful by the China Aerospace Science and Technology Corporation (CASC) a short time after liftoff.

Researchers have made significant progress in understanding the transfer of neutrons in weakly bound nuclei. The experiment, performed at Legnaro National Laboratory, focused on the one-neutron stripping process in reactions involving lithium-6 and bismuth-209. The work is published in the journal Nuclear Science and Techniques.

Will future humans use warp drives to explore the cosmos? We’re in no position to eliminate the possibility. But if our distant descendants ever do, it won’t involve dilithium crystals, and Scottish accents will have evaporated into history by then.
