Beijing and Moscow have agreed that they will “proactively consider strengthening bilateral coordinating measures” to tackle the threat posed by the US and the Republic of Korea’s plan to deploy a powerful antimissile system on the Korean Peninsula.
The consensus was reached during the fourth China-Russia Northeast Asia security consultation in Mosow on Thursday, according to a news release of the Foreign Ministry on Friday.
Assistant Minister of Foreign Affairs Kong Xuanyou and Russian Deputy Foreign Minister Igor Morgulov co-chaired the meeting.
We always hear how bad Russia is; etc. We never hear about these stories where they helped the US.
A U.S. Air Force surveillance plane making a routine flight over Russia to fulfill a treaty obligation was forced to make an emergency landing in eastern Russia earlier this week after experiencing a problem with its landing gear, a Pentagon spokes person told Fox News.
The unarmed American military plane had Russian officials on board as part of the 1992 Open Skies Treaty, which bounds 34 nations, including Russia and the United States, to allow military inspection flights to ensure compliance to long standing arms-control treaties and to offer greater transparency into each nation’s military capabilities.
“On July 27, a U.S. Open Skies Treaty observation aircraft took off from Russian airfield Ulan Ude to begin a Treaty observation flight but the aircraft landing gear did not fully retract,” Lt. Col. Michelle L. Baldanza, a Pentagon spokes person, said in an emailed statement to Fox News.
Among the intriguing issues in plasma physics are those surrounding X-ray pulsars—collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the sky. Physicists want to know the strength of the magnetic field and density of the plasma that surrounds these pulsars, which can be millions of times greater than the density of plasma in stars like the sun.
Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a theory of plasma waves that can infer these properties in greater detail than in standard approaches. The new research analyzes the plasma surrounding the pulsar by coupling Einstein’s theory of relativity with quantum mechanics, which describes the motion of subatomic particles such as the atomic nuclei—or ions—and electrons in plasma. Supporting this work is the DOE Office of Science.
Quantum field theory
The key insight comes from quantum field theory, which describes charged particles that are relativistic, meaning that they travel at near the speed of light. “Quantum theory can describe certain details of the propagation of waves in plasma,” said Yuan Shi, a graduate student in the Princeton Program in Plasma Physics and lead author of a paper published July 29 in the journal Physical Review A. Understanding the interactions behind the propagation can then reveal the composition of the plasma.
If biochemists had access to a quantum computer, they could perfectly simulate the properties of new molecules to develop drugs in ways that would take today’s fastest computers decades. A new device takes us closer to providing such a computer. The device successfully traps, detects, and manipulates an ensemble of electrons above the surface of superfluid helium. The system integrates a nanofluidic channel with a superconducting circuit.
Because they are so small, electrons normally interact weakly with electrical signals. The new device, however, gives the electron more time to interact, and it is this setup that makes it possible to build a qubit, the quantum computing equivalent of a bit. Quantum computers could provide the necessary computing power to model extremely large and complex situations in physics, biology, weather systems and many others.
While isolated electrons in a vacuum can store quantum information nearly perfectly, in real materials, the movements of surrounding atoms disturbs them, eventually leading to the loss of information. This work is a step towards realizing isolated, trapped single electrons by taking advantage of the unique relationship existing between electrons and superfluid helium. Electrons will levitate just above the surface of helium, about 10 nanometers away, insensitive to the atomic fluctuations below. While this effect has been known, holding them in a superconducting device structure has not been demonstrated before this work. At the heart of this new technology is a resonator based on circuit quantum electrodynamics (cQED) architecture, which provides a path to trap electrons above helium and detect the spins of the electrons. Because they are so small, electrons normally interact only very weakly with electrical signals.
Very true POV.
Dry cell biologists, who bridge computer science and cell biology, should have a pivotal role in driving effective team science, says Assaf Zaritsky2.
