Slime mould of Physarum polycephalum is a large cell exhibiting rich spatial non-linear electrical characteristics. We exploit the electrical properties of the slime mould to implement logic gates using a flexible hardware platform designed for investigating the electrical properties of a substrate (Mecobo). We apply arbitrary electrical signals to ‘configure’ the slime mould, i.e. change shape...

Medium from a stationary phase culture of axenically grown D. discoideum cells contains an inhibitor of cohesion of log phase cells. The inhibitor is a heat-stable, low molecular weight substance. Its biological effects include inhibition of cohesion of aggregation-competent cells, of cells of other slime mould species, the blocking of development on Millipore filters and a reduction in adhesiv...

A 25 years old lady with vaginal atresia, secondary to a mismanaged spontaneous vaginal delivery, underwent vaginoplasty using human amnion. The amnion was kept in its place using a 60cc syringe as a mould. For the next three months, dilatation by soft mould was followed by regular intercourse. Alongwith the restoration of normal coital function, she also conceived and was delivered by planned ...

The plasmodium of the slime mould Physarum polycephalum has recently received significant attention for its value as a highly malleable amorphous computing substrate. In laboratory-based experiments, microand nanoscale artificial circuit components were introduced into the P. polycephalum plasmdodium to investigate the electrical properties and computational abilities of hybridised slime mould....

The present study is concerned with the investigation of mechanical properties of A713 alloy castings produced by investment casting process using expandable polystyrene as the pattern material and the plaster of paris as the mould material. Experiments were conducted as per Taguchi’s L9 orthogonal array. Castings were made under the constraint of different process parameters like mould firing ...

Plasmodium of slime mould Physarum polycephalum is a large single celled organism visible unaided by the eye. This slime mould is capable of optimising the shape of its protoplasmic networks in spatial configurations of attractants and repellents. Such adaptive behaviour can be interpreted as computation. When exposed to attractants and repellents, Physarum changes patterns of its electrical ac...

In recent years, the open fit hearing aids have been used widely as they are less prominent and more acceptable to patients. The ear mould is replaced with a dome, which manufacturers claim can reduce the occlusive effect compared to a regular ear mould. The receiver-in-the-canal (RIC) aid, which is a type of open fit aid, also gives a more natural sound quality with better signal to noise rati...

This paper introduces a kind of mechanical structure and its control system, with which granular materials can be put into mould with a higher leveling status, the mechanical structure adopts split type arrangement, its function is to achieve the material removal and scraping, its control system is composed of a plurality of Mitsubishi PLC using masterslave control method. The mechanism and con...
