The smartphone’s built-in camera acquired images of slides for each microscopic field of view. falciparum-infected and 50 healthy patients were collected and photographed at Chittagong Medical College Hospital, Bangladesh. Giemsa-stained thin blood smear slides from 150 P.

To reduce the burden for microscopists in resource-constrained regions and improve diagnostic accuracy, researchers at the Lister Hill National Center for Biomedical Communications (LHNCBC), part o f National Library of Medicine (NLM), have developed a mobile application that runs on a standard Android smartphone attached to a conventional light microscope. Figure 1: a) Borromean Rings, b) Hilbert Curve, c) Yin-Yang. In many cases, the solutions can also be developed into attractive geometrical sculptures. The proffered solutions lead to interesting discus-sions of fundamental issues concerning acceptable analogies, the role of symmetry, degrees of free-dom, and evaluation criteria to compare the relative merits of the different proposals. Examples include: constructing a Hilbert curve in 3D-space, finding an analogous constellation to the Borromean rings with four or more loops, or developing 3D shapes that capture the essence of the 2D Yin-Yang figure or of a logarithmic spiral. Students in a graduate course on geometric modeling are challenged with open-ended design exercises that introduce them to this analogical reasoning and, hopefully, enhance their creative thinking abilities. drawings in a 2-dimensional plane, into higher dimensions where model making and visualization are much harder to carry out. In the realm of geometrical proofs and geometrical art, such analogies can carry concepts and methods from spaces that are easy to deal with, e.g. Human creativity relies to a large part on our ability to recognize and match patterns, to transpose these patterns into different domains, and to find analogies in new domains to known facts in old domains.

As a practical example, the paper shows how to use the proposed confidence values to highlight manifestations of tuberculosis in frontal chest X-rays. The paper underpins this thesis with theoretical results in neural signal processing, stating that a sine/cosine relationship between the actual input signal and the perceived (learned) input is key to neural learning processes. The paper claims that the proposed confidence is intuitive and can be readily understood by physicians. The angle for which sine and cosine are equal (45°) represents the state of equilibrium between Yin and Yang, which is a state of nonduality that indicates neither normality nor abnormality in terms of disease classification. The paper shows how this confidence is motivated by Chinese medicine and how sine/cosine values are directly related with the two forces Yin and Yang. This paper argues in favor of a specific type of confidence for use in computer-aided diagnosis and disease classification, namely, sine/cosine values of angles represented by points on the unit circle.
