How would you like to store all the films ever made on a device the size of an Apple iPhone? Magnets made of just a few metallic atoms could make it possible to build radically smaller storage devices and have also recently been proposed as components for spintronics devices. There’s just one obstacle on the …
In this phase diagram common to many cuprate superconductors, the insulating phase typical of undoped cuprate compounds appears at the far left (black). Other phases appear with increased hole doping – the dome-shaped superconducting phase below Tc (blue), the mysterious pseudogap below T* (red), and a “normal metallic” phase (white). New evidence from studies of …
There is on the order of 7000 deaths per year from terrorism. state department stats on terrorism Most of it is terrorism within Afghanistan and Iraq. Global terrorism has far lower numbers of about 300-700 per year (other than in 2001). There were about 200,000 murders in the world (2000). 2-3% are likely arson, which …
IAEA update log for Fukushima nuclear plant. Japanese authorities have notified the IAEA that efforts to restore power for the Fukushima Daiichi nuclear plant are on-going. As of 19 March at 21:46 UTC, the power centre at Unit 2 had received electricity. Work to restore electricity to Units 3 and 4 is continuing. White smoke …
NEI – UPDATE AS OF 11:20 A.M. EDT, FRIDAY, MARCH 18: Reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant are in stable condition, with workers continuing to provide seawater cooling into the reactors. Containment integrity is believed to be intact on reactors 1, 2 and 3, and containment building pressures are …
On Friday the first day of the quake, Google’s offices in Tokyo’s Roppongi district contacted Google.org, their employer’s philanthropic arm, to suggest it should get involved in the emergency response, as it had after recent earthquakes in Haiti, Chile and New Zealand. Within an hour, and with aftershocks still rocking Tokyo, the Japan Person Finder …
Procedures that the Fukushima nuclear plant workers would be following to deal with high R=radiation dose rates (like the high readings of 40 REM/hr) – move to an area with a lower dose rate. Radiation dose rates obey physical laws – if you double your distance from the source, you reduce the rate by a …
Examples of the electron density maps Researchers have solved the three-dimensional structure of a key biological receptor. The finding has the potential to speed drug discovery in many areas, from arthritis to respiratory disorders to wound healing, because it enables chemists to better examine and design molecules for use in experimental drugs. The researchers are …
IAEA report- Japanese authorities also today informed the IAEA at 04:50 CET that the spent fuel storage pond at the Unit 4 reactor of the Fukushima Daiichi nuclear power plant is on fire and radioactivity is being released directly into the atmosphere. Dose rates of up to 400 millisievert per hour have been reported at …
Experiment to illustrate the P-CTC predictions of the grandfather paradox. a) Diagram of the quantum circuit. Using a CNOT gate sandwiched between optional Z and X gates, it is possible to prepare all of the maximally entangled Bell states. The Bell state measurement is implemented using a CNOT and a Hadamard. Each of the probe …
A team led by Jan Schroers, a materials scientist at Yale University, has shown that some recently developed bulk metallic glasses (BMGs)-metal alloys that have randomly arranged atoms as opposed to the orderly, crystalline structure found in ordinary metals-can be blow molded like plastics into complex shapes that can’t be achieved using regular metal, yet …
