Physicists Puzzle Over Emergence of Strange Electron Aggregates

Posted by in categories: materials, particle physics

In the last year, two independent groups have observed electrons behaving like quasiparticles with fractional amounts of charge, like –²⁄₃ and –³⁄₅, without the influence of a magnetic field.


In the 127 years since the electron was discovered, it has undergone more scrutiny than perhaps any other particle. As a result, its properties are not just well known, but rote, textbook material: Electrons have a smidgen of mass and negative electric charge. In a conductor, they swim relatively unimpeded as a current; in an insulator, they barely move.

Over time, caveats have cropped up. Under an intense magnetic field, for example, electrons can lose their individual identities and form “quasiparticles”: collective entities, like the shape formed by a school of fish. But even these collective states have been well cataloged.

2BP: 2-Stage Backpropagation

Posted by in category: robotics/AI

2BP

2-Stage Backpropagation.

As Deep Neural Networks (DNNs) grow in size and complexity, they often exceed the memory capacity of a single accelerator, necessitating the sharding of model parameters across multiple accelerators.

You can watch astronauts at the International Space Station receive 3 tons of supplies: Here’s how

Posted by in categories: energy, food, space

Space lovers have an opportunity to watch two unique occurrences at the International Space Station this week, but you will have to stay up pretty late — or wake up very early — to see them live.

According to NASA, the cargo spacecraft carrying three tons of food, fuel and supplies to the ISS is for the Expedition 71 crew.

The unpiloted spacecraft – called Progress 88 – is scheduled to launch on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan on Thursday at 2:43 p.m. local time.

Researchers uncover strange symptom that could be first sign of Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

New symptoms such as failing to identify more than one object at a time and a “space perception deficit” could be the first signs of Alzheimer’s disease, a new study has found.

Posterior cortical atrophy (PCA), is a diagnosis for those who struggle with judging distances, distinguishing between moving and stationary objects and completing tasks like writing and it overwhelmingly predicts Alzheimer’s.

In the latest study from researchers at the University of California, San Francisco, some 94 per cent patients with PCA had Alzheimer’s pathology. Most patients with PCA have normal cognition early on, but by the time of their first diagnostic visit, an average 3.8 years after symptom onset, mild or moderate dementia was apparent with deficits identified in memory, executive function, behavior, and speech and language , according to the researchers’ findings.

Research team demonstrates modular, scalable hardware architecture for a quantum computer

Posted by in categories: computing, engineering, particle physics, quantum physics

The team spent years perfecting an intricate process for manufacturing two-dimensional arrays of atom-sized qubit microchiplets and transferring thousands of them onto a carefully prepared complementary metal-oxide semiconductor (CMOS) chip. This transfer can be performed in a single step.

“We will need a large number of qubits, and great control over them, to really leverage the power of a quantum system and make it useful. We are proposing a brand new architecture and a fabrication technology that can support the scalability requirements of a hardware system for a quantum computer,” says Linsen Li, an and computer science (EECS) graduate student and lead author of a paper on this architecture.
