    Abstract
    PageRank is defined as the stationary state of a Markov chain. The chain is obtained by perturbing the transition matrix induced by a web graph with a damping factor alpha that spreads uniformly part of the rank. The choice of alpha is eminently empirical, and in most cases the original suggestion alpha=0.85 by Brin and Page is still used. Recently, however, the behaviour of PageRank with respect to changes in alpha was discovered to be useful in link-spam detection. Moreover, an analytical justification of the value chosen for alpha is still missing. In this paper, we give the first mathematical analysis of PageRank when alpha changes. In particular, we show that, contrarily to popular belief, for real-world graphs values of alpha close to 1 do not give a more meaningful ranking. Then, we give closed-form formulae for PageRank derivatives of any order, and an extension of the Power Method that approximates them with convergence O(t**k*alpha**t) for the k-th derivative. Finally, we show a tight connection between iterated computation and analytical behaviour by proving that the k-th iteration of the Power Method gives exactly the PageRank value obtained using a Maclaurin polynomial of degree k. The latter result paves the way towards the application of analytical methods to the study of PageRank.

    Abstract
    Two new methods for retrieving mathematical expressions using conventional keyword search and expression images are presented. An expression-level TF-IDF (term frequency-inverse document frequency) approach is used for keyword search, where queries and indexed expressions are represented by keywords taken from LATEX strings. TF-IDF is computed at the level of individual expressions rather than documents to increase the precision of matching. The second retrieval technique is a form of Content-Base Image Retrieval (CBIR). Expressions are segmented into connected components, and then components in the query expression and each expression in the collection are matched using contour and density features, aspect ratios, and relative positions. In an experiment using ten randomly sampled queries from a corpus of over 22,000 expressions, precision-at-k (k= 20) for the keyword-based approach was higher (keyword: µ= 84.0,s= 19.0, image-based:µ= 32.0,s= 30.7), but for a few of the queries better results were obtained using a combination of the two techniques.

    Abstract
    Bezugnahme auf: Lehmann, K.: Denken mit Leib und Seele. Unter: https://www.heise.de/tp/features/Denken-mit-Leib-und-Seele-3593478.html. Konrad Lehmann wies in seinem Artikel vom 27. Mai auf Probleme hin, Bewusstsein naturwissenschaftlich zu erklären. Er kritisierte das uneingelöste Versprechen des Materialismus beziehungsweise Physikalismus und diskutierte alternative Ansätze, wie den Panpsychismus, Idealismus und praktischen Materialismus. Meiner Meinung nach muss man Aussagen über das Sein (also ontologische Aussagen) klarer von Aussagen über unsere Erkenntnis (also epistemische Aussagen) trennen, als Lehmann dies getan hat. Außerdem sollte man ein Problem klarer definieren, bevor man es diskutiert. Nach einer Replik auf den Artikel Lehmanns möchte ich meine eigenen Gedanken zum Leib-Seele-Problem zur Diskussion stellen. Dabei gehe ich auch auf Aussagen über den Erkenntniswert der Neurowissenschaften zum Verständnis des Bewusstseins ein. Mein Vorschlag ist, sich vom traditionellen Leib-Seele-Problem zu verabschieden, da es eher ein Problem unseres Denkens als ein Problem der Welt ist. Replik darauf: Lehmann, K.: Geist? Welcher Geist?. [04. Juni 2017]. Unter: https://www.heise.de/tp/features/Geist-Welcher-Geist-3733426.html.
