An extensive intraoral maxillofacial prosthesis presents challenges to the clinician in many ways. The problems encountered include that of support and retention of the prosthesis. These problems arise due to unfavorable anatomical configuration of the defect. This unfavorable configuration may prompt the clinician to device alternate /additional means of support and retention. The aim of this ...

This report provides an overview of the current state of the art deep learning architectures and optimisation techniques, and uses the ADNI hippocampus MRI dataset as an example to compare the effectiveness and efficiency of different convolutional architectures on the task of patch-based 3dimensional hippocampal segmentation, which is important in the diagnosis of Alzheimer’s Disease. We found...

This paper introduces BioComputer Music, an experimental one-piano duet between pianist and plasmodial slime mould Physarum polycephalum. This piece harnesses a system we have been developing, which we call BioComputer. BioComputer consists of an analogue circuit that encompasses components grown from the biological computing substrate Physarum polycephalum. Our system listens to the pianist an...

Physics imposes some limits to the computations that we can perform. Because of these limits we cannot solve problems in almost no time and with almost zero energy consumption. The main problem is that we are asking too much from a single device: we want computers that play chess, solve equations, navigate on the internet etc. Because of this great generality we are paying some big prices (in t...

objective(s): there are few reports have demonstrated the effect of a change-in-light experience on the structure and function of hippocampus. a change-in-light experience also affects the circadian pattern of melatonin secretion. this study aimed to investigate developmental effect of exogenous melatonin on synaptic plasticity of hippocampus of light deprived rats. materials and methods: the e...

neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life. neuroplasticity allows the neurons in the brain to compensate injury and disease and to adjust their activities in response to new situations or to changes in their environment. at the other side, it is now well established that neuronal function is strongly influenced by both cen...

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

Based on the cellular automaton principle and multi-agents theory of complex systems, the generation and the evolutionary mechanism of unconventional emergencies have been studied and the twice-linked model of he evolutionary mechanism of unconventional emergencies has been established with calculating experiments being carried out in this study. The conclusion is reached that the internal caus...

The rather inappropriately named ‘unconventional’ myosins — unconventional in comparison with the betterknown muscle myosin — are a superfamily of actin-based motor proteins, characterized by a conserved motor domain that generates ATP-dependent movement along actin [1]. Unconventional myosins have been found to be responsible for numerous cellular movements, such as cytokinesis, pseudopod exte...
