This study focuses on the slip prediction in a cable-drum system using artificial neural networks for the prospect of developing linear motion sensing scheme for such mechanisms. Both feed-forward and recurrent-type artificial neural network architectures are considered to capture the slip dynamics of cable-drum mechanisms. In the article, the network development is presented in a progressive (step-by-step) fashion for the purpose of not only making the design process transparent to the readers but also highlighting the corresponding challenges associated with the design phase (i.e. selection of architecture, network size, training process parameters, etc.). Prediction performances of the devised networks are evaluated rigorously via an experimental study. Finally, a structured neural network, which embodies the network with the best prediction performance, is further developed to overcome the drift observed at low velocity. The study illustrates that the resulting structured neural network could predict the slip in the mechanism within an error band of 100 µm when an absolute reference is utilized.

An investigation of the breeding habits of the yellow fever mosquito, Aëdes aegypti, Linn., in West Africa was begun in December 1925. This was undertaken for the purpose of ascertaining if the selection of breeding-places of this mosquito in Africa differs from that in the Western Hemisphere, and, if so, to learn if this difference is sufficient to be of material importance in yellow fever control work.Since it was believed that breeding in tree-holes constituted a problem worthy of investigation, it was decided to make a survey of the rot-holes and fork-hollows in trees in the vicinity of Lagos, in the Southern Province of Nigeria. This survey was begun on 8th December 1925, shortly after the rainy season had passed and the dry season had set in. However, after inspecting a number of trees, the fact became evident that this was not a propitious time of the year for finding larvae in such places, since practically all of the holes were without water, and their contents, consisting of leaves and débris, were dry.This early drying of the material in the holes drew my attention to the probability of mosquito eggs remaining in the holes, surviving the drought of the dry season and producing larvae with the beginning of the rains. In furtherance of this question, an examination of the dry holes was then began, and material collected from all those that were suitable. The term “ suitable ” in this sense signifies that the hole was in a living tree—of a formation to contain water, for a short time at least—that the aperture was of sufficient size to allow the débris to be removed and the inside of the hole scraped, and that the contents were dry. The distance of the trees from habitations, their location in open areas or thick bush, the height of the holes from the ground, the exposure of the holes to the sun, or the amount of débris contained caused no discrimination to be made.

Sulfide is known to be an important factor in microbiologically influenced corrosion (MIC) of metals and concrete deterioration in wastewater treatment structures and sewer pipelines. A sulfide biosensor was used to determine the effectiveness of Escherichia coli DH5α biofilm as a protective barrier against MIC. The biofilm was shown to be effective in protecting surfaces from sulfide and helping to reduce MIC using amperometric measurements. The results also indicated that the growth conditions of E. coli DH5α may have an impact on the performance of the biofilm as a sulfide barrier. The simple method provided in this work enables the comparison of several microbial biofilms and selection of the ones with potential to prevent MIC in a relatively short time.

John Graham Kerr was born on 18 September 1869, at Arkley, Herts, the son of James Kerr, M.A., a former Principal of Hoogly and Hindu College, Calcutta, and of Sybella Graham, of Hollows, Dumfriesshire. He was third in a family of four with three sisters. His father was a well-known educationalist and the author of various works dealing with a number of topics including Indian educational problems, English orthography and aspects of human nature, and Thomas Carlyle. Graham Kerr, as he was known throughout the greater part of his life, lost his mother in early childhood and grew up under the influence of his father who although his tastes were mainly literary had a broad interest in general science, especially in natural history and evolution, in which he was widely read. His father superintended the early stages of his education, including latin and mathematics, and encouraged the reading of such books as Darwin’s The voyage of the Beagle , Waterton’s Wanderings , Wallace’s Amazon and Malay Archipelago , etc. In addition, his library contained a large selection of classical works, especially poetry and history, and Graham Kerr was brought up in a general atmosphere of literary culture. His schooling began at the parish school of Dalkeith, Midlothian, under William Young, a good example of the old-fashioned type of parish schoolmaster who did not hesitate to give special time and attention to any boy who in his opinion possessed the natural capacity to benefit by his teaching. After a short time at the Collegiate School, Edinburgh, he passed on to the Royal High School, where he was specially influenced by Munn, the mathematics master under whose tuition he became Dux of the Fifth Form. He subsequently enrolled in the University of Edinburgh and first concentrated on higher mathematics and natural philosophy. He then studied geology, botany and zoology and finally decided to follow out the curriculum in medicine. This was interrupted when on a wintry afternoon in February 1889, this young medical student of nineteen, returning home from his classes picked up a copy of Nature at the book-stall in Waverley Station, and read an announcement which in his own words ‘determined the whole future of my life’.

A great variety of computational approaches support drug design processes, helping in selection of new potentially active compounds, and optimization of their physicochemical and ADMET properties. Machine learning is a group of methods that are able to evaluate in relatively short time enormous amounts of data. However, the quality of machine-learning-based prediction depends on the data supplied for model training. In this study, we used deep neural networks for the task of compound activity prediction and developed dropout-based approaches for estimating prediction uncertainty. Several types of analyses were performed: the relationships between the prediction error, similarity to the training set, prediction uncertainty, number and standard deviation of activity values were examined. It was tested whether incorporation of information about prediction uncertainty influences compounds ranking based on predicted activity and prediction uncertainty was used to search for the potential errors in the ChEMBL database. The obtained outcome indicates that incorporation of information about uncertainty of compound activity prediction can be of great help during virtual screening experiments.
