Helium-2 (diproton) Helium-2 or 2 He , also known as a diproton, is an extremely unstable isotope of helium that consists of two protons without any neutrons . According to theoretical calculations it would have been much more stable (although still beta decaying to deuterium ) had the strong force been 2% greater. Its instability is due to spin-spin interactions in the nuclear force, and the Pauli exclusion principle , which forces the two protons to have anti-aligned spins and gives the diproton a negative binding energy . There may have been observations of 2 He . In 2000, physicists first observed a new type of radioactive decay in which a nucleus emits two protons at once—perhaps a 2 He nucleus. The team led by Alfredo Galindo-Uribarri of the Oak Ridge National Laboratory announced that the discovery will help scientists understand the strong nuclear force and provide fresh insights into the creation of elements inside stars . Galindo-Uribarri and co-workers chose an isotope of neon with an energy structure that prevents it from emitting protons one at a time. This means that the two protons are ejected simultaneously. The team fired a beam of fluorine ions at a proton-rich target to produce 18 Ne , which then decayed into oxygen and two protons. Any protons ejected from the target itself were identified by their characteristic energies. There are two ways in which the two-proton emission may proceed. The neon nucleus might eject a 'diproton'—a pair of protons bound together as a 2 He nucleus—which then decays into separate protons. Alternatively, the protons may be emitted separately but at the same time—so-called 'democratic decay'. The experiment was not sensitive enough to establish which of these two processes was taking place. More evidence of 2 He was found in 2008 at the Istituto Nazionale di Fisica Nucleare , in Italy. A beam of 20 Ne ions was directed at a target of beryllium foil. This collision converted some of the heavier neon nuclei in the beam into 18 Ne nuclei. These nuclei then collided with a foil of lead. The second collision had the effect of exciting the 18 Ne nucleus into a highly unstable condition. As in the earlier experiment at Oak Ridge, the 18 Ne nucleus decayed into an 16 O nucleus, plus two protons detected exiting from the same direction. The new experiment showed that the two protons were initially ejected together, correlated in a quasibound 1 S configuration, before decaying into separate protons much less than a billionth of a second later. Further evidence comes from RIKEN in Japan and JINR in Dubna , Russia, where beams of 6 He nuclei were directed at a cryogenic hydrogen target to produce 5 He . It was discovered that the 6 He nucleus can donate all four of its neutrons to the hydrogen. The two remaining protons could be simultaneously ejected from the target as a 2 He nucleus, which quickly decayed into two protons. A similar reaction has also been observed from 8 He nuclei colliding with hydrogen. 2 He is an intermediate in the first step of the proton-proton chain reaction . The first step of the proton-proton chain reaction is a two-stage process; first, two protons fuse to form a diproton: 1 1 H + 1 1 H → 2 2 He followed by the immediate beta-plus decay of the diproton to deuterium: 2 2 He → 2 1 D + e + + ν e with the overall formula: 1 1 H + 1 1 H → 2 1 D + e + + ν e + 0.42 MeV R. A. W. Bradford has considered the hypothetical effect of this isotope on Big Bang and stellar nucleosynthesis.
When you fully trust a person without any doubt, you finally get one of the two results: a person for life, or a lesson for life. 当你毫不怀疑地相信一个人，那么你最终有可能得到两种结果：要么得到一个值得托付一生的人，要么得到一个铭记一生的教训。
In-the-money: A call option is in-the-money when its strike price is below the current trading price of the underlying asset. A put option is in-the-money when its strike price is above the current trading price of the underlying asset. In-the-money options are generally more expensive as their premiums consist of significant intrinsic value on the top of their time value. Out of money option: An option without any intrinsic value is an out-of-the-money (OTM) option. A call option is out-of-the-money when the strike price is above the current trading price of the underlying security. Intrinsic value: option value if it expired immediately. Intrinsic call value=max(S-X,0). Intrinsic value 0, then the option is in the money. Speculative Value: Speculative Value=Option Price - Intrinsic Value

The Evolution Of US And UK Central Banking: An Infographic Submitted by Tyler Durden on 12/03/2012 21:50 -0500 Federal Reserve United Kingdom Investors once knew: Focusing on assets without understanding monetary matters can get you into trouble. They have since forgotten this. Ironically, then, there’s great value in remembering it. As “Vermont Ruminator”, Humphrey B. Neill, wrote in The Art of Contrary Thinking: is a study in itself and one which still confuses the great minds of the world... ...because monetary problems are not comprehended by the public or by the average businessman, “money management” will continually cross up public opinions concerning economic trends... ...If you make it a point to become posted on some of the more common practices of monetary management you will …be able to discern trends that are opposite to those commonly discussed... This addogram delves into the evolution of the two most prominent reserve currencies of the past 350 years: The pound sterling and the dollar. It features visualizations of a collection of extremely rare (if not entirely unique) data-sets . The Bank of England’s assets and liabilities since Robert Peel’s Bank Act of 1844 (monthly). And the Federal Reserve System’s assets and liabilities since shortly after its creation (weekly). The yield, equity index and gold price section goes back as far as 1840 . This pairing of comprehensive monetary and asset price data gives the addogram an intensely practical feel. Click chart below for huge version...

Friday Humor: "I Am Pledging To Cut The Deficit We Inherited By Half By The End Of My First Term In Office" Submitted by Tyler Durden on 08/03/2012 17:48 -0400 President Obama President Obama, February 2009 " We can not and will not sustain deficits like these without end . Contrary to the prevailing wisdom in Washington these past few years, we can not simply spend as we please and defer the consequences to the next budget, the next administration or the next generation. We are paying the price for these deficits right now. In 2008 alone we paid $250 billion in interest on our debt, that is more than three times what we spent on education that year, more than seven times what we spent on VA healthcare . So if we confront this crisis without also confronting the deficits that helped cause it, we risk sinking into another crisis down the road as our interest payments rise, our obligations come due, confidence in our economy erodes and our children and grandchildren are unable to pursue their dreams because they are saddled with our debts. That's why today I am pledging to cut the deficit we inherited by half by the end of my first term in office . This will not be easy - it will require us to make difficult decisions and face challenges we have long neglected but i refuse to leave our children with a debt they can not repay. And that means taking responsibility right now in this administration, for getting our spending under control ."
