It’s unclear what customers or applications might be earmarked for this node, but it’s possible it could be dedicated to IoT and other consumer devices that need to sip power. Typically, these applications use legacy nodes as it would be too expensive to use advanced processes for inexpensive devices, but TSMC is planning for the future since this effort won’t be realized until 2029 or so.

TSMC’s Dr. Kevin Zhang, senior vice president of business development and overseas Operations, says the company has already started building Greenfield, but he didn’t indicate where it’s located. He says the rapid deployment of the Greenfield fab is the first time the company has essentially skipped what we assume is a lengthy review process and put shovels in dirt already.

According to Zhang, TSMC’s move is part of its larger effort to build some resiliency into its global supply chain. That resiliency will be achieved both by building fabs outside of Taiwan and increasing capacity for nodes it thinks will be in demand in the future. Anandtech notes the company’s most advanced low-power node is currently N6e, which is a 6nm/7nm node that uses between 0.4V and 0.9V. For N4e, the company is reportedly looking to drop that all the way down to 0.4V, but it didn’t offer any additional details about its performance or attributes at the symposium.

I met Prof. Ed Boyden at last year’s Global Future 2045 conference in New York. There I was highly impressed with Boyden’s impressive work in neuroscience in general and optogenetics in particular, as well as the profound implications it would have on our ability to understand and manipulate the brain. And so I knew instantly I must bring him for an interview.

In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction.

Now, new research reveals yet another engineering feat of this ancient animal’s structure: its ability to filter feed using only the faint ambient currents of the ocean depths, no pumping required.

This discovery of natural ‘“zero energy” flow control by an international research team co-led by University of Rome Tor Vergata and NYU Tandon School of Engineering could help engineers design more efficient chemical reactors, air purification systems, heat exchangers, hydraulic systems, and aerodynamic surfaces.

In a study published in Physical Review Letters, the team found through extremely high-resolution computer simulations how the skeletal structure of the Venus flower basket sponge (Euplectella aspergillum) diverts very slow deep sea currents to flow upwards into its central body cavity, so it can feed on plankton and other marine detritus it filters out of the water.

Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theory (QFT): a theoretical framework that combines principles from classical, quantum, and relativistic physics, and serves as the foundation of the Standard Model of particle physics.

Microwave dielectric ceramics are the cornerstone of wireless communication devices, widely utilized in mobile communications, satellite radar, GPS, Bluetooth, and WLAN applications. Components made from these ceramic materials, such as filters, resonators, and dielectric antennas, are extensively used in wireless communication networks.

Due to the presence of non-Hermitian components, wave intensities tend to localize at the system boundary, namely the non-Hermitian skin effect. The skin behavior is protected by topology, making it insensitive to minor changes. Nevertheless, it has recently been shown that the non-Hermitian skin effect can be suppressed by real magnetic fields.

Zhang, Xue, and Zhang’s graduate student Hau Tian Teo wondered, “Can a ‘fake’ magnetic field —pseudomagnetic field—also suppress the non-Hermitian skin effect?” The team then performed theoretical calculations on a two-dimensional lattice array to study the topology and movement of the skin behavior.

By switching on the pseudomagnetic field, the team discovered that the skin states can be pushed into the bulk. “This movement from skin to bulk can be precisely traced by a theoretically predicted trajectory,” Teo suggests. In addition to the movement, the suppression is reflected in the reduction of topological number.

Disgust is one of the six basic human emotions, along with happiness, sadness, fear, anger, and surprise. Disgust typically arises when a person perceives a sensory stimulus or situation as revolting, off-putting, or unpleasant in other ways.
