绒泡菌船:如果疟原虫航行,它永远不会离开港口。
Physarum boats: If plasmodium sailed it would never leave a port
摘要:
\emph{Physarum polycephalum}的疟原虫是一个巨大的(肉眼可见)细胞,有无数的细胞核。疟原虫是一种很有前途的非经典的,自然启发,计算设备的基板。它具有最短路径近似、平面邻近图和平面镶嵌计算、图元记忆和决策等功能。疟原虫的独特性质使其成为具有大规模并行信息处理和分布式输入和输出的无定形生物机器人的理想候选者。我们发现,当附着在轻重量的物体上休息在水面上的原质团可以推动振荡的原生质伪足的对象。在实验室条件下和计算实验中,我们研究了疟原虫-漂浮物系统的现象学,以及控制由船上疟原虫推动的物体运动的可能机制。
英文摘要:
Plasmodium of \emph{Physarum polycephalum} is a single huge (visible by naked eye) cell with myriad of nuclei. The plasmodium is a promising substrate for non-classical, nature-inspired, computing devices. It is capable for approximation of shortest path, computation of planar proximity graphs and plane tessellations, primitive memory and decision-making. The unique properties of the plasmodium make it an ideal candidate for a role of amorphous biological robots with massive parallel information processing and distributed inputs and outputs. We show that when adhered to light-weight object resting on a water surface the plasmodium can propel the object by oscillating its protoplasmic pseudopodia. In experimental laboratory conditions and computational experiments we study phenomenology of the plasmodium-floater system, and possible mechanisms of controlling motion of objects propelled by on board plasmodium.
