Nanogranular Fe/(InO)films with complex magnetic structure were prepared by the rf sputtering method. An extra-large magnetoresistance up to 506% was obtained at 2.2 K, which is two orders of magnitude larger than that obtained at room temperature. This is related to the interaction with the ...

In previous studies it has been shown that a good case can be made for supposing that a large fraction of the primary cosmic rays is of extra-galactic origin. These ideas are reviewed here, and the most recent observations and theoretical suggestions bearing on the problem are described.关键...

The technique developed for controlling adaptive secondary mirrors ## 1:5 mm thick, # 1 m size, # 1000 actuators#, is directly relevant for extremely thin mirrors of any size, including the segments of extra-large primary mirrors. Simulations and laboratory measurements on prototype adaptive secon...

超对称也是欧洲大型强子对撞机(large hadron collider, LHC)除已发现的Higgs粒子外的另一重要科学目标(额外维也是其中之一). 具有这种对称性的理论称为超对称理论. 当超对称变换参数不依赖时空位置时, 这种超对称称为整体超对称. 这样的理论不涉及引力. 研究表明, 这样的理论存在的最大时空维度是6维时空...
