These included an image analysis system to assess the facial mobility of people who are suffering from paralysing diseases or have had surgery on the face; a "text mining" tool to extract chemical information from the world's scientific literature; an educational venture, called Big Bang in a Box, to sell images of high-energy particle collisions at Cern's new atom smasher; and a lightweight material stronger than steel, for use in body armour and the aerospace industry.

By systematically analyzing the single particle level and the occupation probability near the Fermi surface,and the rule of nuclear particle number deviations with proton numbers for N =8,20,28,50,82,126 neutron chains within the relativistic mean-field model with BCS theory,we have discussed the stability of the shell structure for the traditional neutron magic in the whole range of nuclear spectrum from neutron line to proton line,and predicted that traditional neutron magic number effect shall possibly disappear only in light neutron-rich nuclei.

The atom drifts to where it wants to go, said Dr. Landua, namely the wall where its components will annihilate with their opposite numbers in a characteristic pattern: the antiproton into a spray of lighter particles called pions, and the positron producing a flash of gamma rays.

Landua 博士说，&原子随意漂流&，即组成的墙壁会消灭以相反特性存在的粒子数：反质子进入比较轻的称作介子的粒子雾里，而正电子产生伽马射线闪光。

As for the study of isospin in intermediate energy HICs, we've investigated how bothstength and density dependence of symmetry potential affect many measurableobservables, such as the yield, phase-space, and isospin distributions of fragments, as wellas the correlations between Intermediate-Mass-Fragment multiplicity 〓 andCharged-Particle multiplicity 〓 Light-Charged-Particle multiplicity 〓 andNeutron multiplicity 〓. The aim is to find sensitive observables specifically for strengthand density dependence of SP.
