简介：在动人的水平圆柱的热来源附近阶段变化材料融化的接触，在它的自己的重量下面下降了，在这篇文章被调查。在经常的表面热流动下面的一个融化的模型被建立。厚度和压力分布里面的分析结果融化层，稳定的融化速度被使用融化理论的接触获得。融化的法律被讨论，并且由温度差别与接触融化的相比开车。伪稳定的融化速度被热来源密度的热来源，和变化的热流动决定，这被发现在融化上有更少的效果速度。

简介：我们为创造在在超导的流动qubit附近放的二个分开的氮空缺中心旋转整体之间的宏观的纠缠的协调状态建议一个潜在地实际的计划。通过集体磁性的联合并且在里面流动qubit的situtunability，旋转整体的任意的纠缠的协调状态能从流动qubit和旋转整体的decoherence在影响下面与高成功可能性被完成。试验性的可行性和挑战用当前可得到的技术被认为正当。

简介：non-Gaussian噪音驾驶的一个随机的消散的动态系统被调查。系统的一个一般近似佛克普朗克常数方程通过一条路径积分途径被导出。基于香农的信息熵，熵流动的准确时间依赖和系统的熵生产的定义在缺席并且面对非平衡被计算限制。现在的计算能被用来在熵流动和熵生产上解释消散的常数和non-Gaussian噪音的相互影响。

简介：分子的动态模拟被执行在交流上调查事件精力的效果:从C和H的H电影生长原子流动。我们的模拟证明在低事件精力(1eV)的电影生长被H和C原子的吸附统治。在中等事件精力(10和20eV)，有在表面吸附的H原子的事件H原子的抽象反应变得重要。在高事件精力(30和40eV)，交流:H电影生长是一个二拍子的圆舞过程：一个人是吸附和C原子的浅培植，并且其它是H原子的深培植。[从作者抽象]
