Plasticity in connections between neurons allows learning and adaptation, but it also allows noise to degrade the function of a network. Ongoing network self-repair is thus necessary. We describe a method to derive spike-timing-dependent plasticity rules for self-repair, based on the firing patterns of a functioning network. These plasticity rules for self-repair also provide the basis for unsu...

This study focused on the development of a crack repair stick as a new repair method along with self-healing materials that can be used to easily repair the cracks in a concrete structure at the construction site. In developing this new repair technique, the self-healing efficiency of various cementitious materials was considered. Likewise, a crack repair stick was developed to apply to concret...

Purpose This study evaluated the effects of different adhesive systems on repair bond strength of aged resin composites. Materials and Methods Ninety composite discs were built and half of them were subjected to thermal aging. Aged and non-aged specimens were repaired with resin composite using three different adhesive systems; a two-step self-etch adhesive, a two-step total-etch adhesive and...

Self-reconfigurable modular robots consist of multiple elements and have the potential to enable future autonomous systems adapt themselves handle unstructured environments, novel tasks, or damage their constituent elements. This paper considers methods self-assembly, bringing together robotic modules form larger organism-like structures, self-repair, removing replacing faulty damaged by intern...

Self-repair robots are modular robots that have the capability of detecting and recovering from failures. Typically, such robots are unit-modular and carry a number of redundant modules on their bodies. Self-repair consists of detecting the failure of a module, ejecting the bad module and replacing it with one of the extra modules. In this paper we show how self-repair can be accomplished by se...

This study reveals in detail the mechanism of self-repair during secondary growth in the vines Aristolochia macrophylla and Aristolochia ringens based on morphological data. For a comprehensive understanding of the underlying mechanisms during the self-repair of lesions in the sclerenchymatous cylinder of the stem, which are caused by internal growth stresses, a classification of morphological ...
