We extend the study of Akiyama’s tile-makers: surfaces whose developments all tile the plane. First, we prove that the developments of Akiyama’s tile-makers are the prototiles that tile the plane isohedrally with rotation and without reflection. Second, we give a simple characterization of all closed (boundaryless) tile-makers and give three new tile-makers not known to Akiyama. Finally, we pro...

We consider the problem of segmenting an image into foreground and background, with foreground containing solely objects of interest known a priori. We propose an integration model that incorporates both edge detection and object part detection results. It consists of two parallel processes: low-level pixel grouping and high-level patch grouping. We seek a solution that optimizes a joint groupi...

A 10-year-old girl presented with a 1-year history of an eruption on her hands. Physical examination revealed soft, bluish slightly tender subcutaneous nodules and swellings in the ulnar site and palmar aspect of five fingers of the right hand and dorsal aspect of three fingers of the left hand without any gross deformity in fingers and long bones (figure 1). History of pathological fract...

The patient was a 19 year-old woman with the diagnosis of resistant hypertension, although she was under treatment of three classes of anti-hypertensive drugs (beta blocker, angiotensin receptor blocker, diuretic) for more than one year. In physical examination there was only a significant difference between the systolic blood pressure of upper and lower extremities (200 vs. 120 mmHg), without ...

the value of good X (x-axis) and such that the response is menu dependent (red when X is offered against Y, blue when X is offered against Z). Transitivity violations (i.e., cases where x-axis orderings are not conserved on the y-axis) are possible, as for X1, X2, X3. However, if the representation is menu invariant (i.e., if red and blue lines coincide), transitivity violations cannot occur. I...

MOTIVATION Figures from biomedical articles contain valuable information difficult to reach without specialized tools. Currently, there is no search engine that can retrieve specific figure types. RESULTS This study describes a retrieval method that takes advantage of principles in image understanding, text mining and optical character recognition (OCR) to retrieve figure types defined concep...

This article introduces MLPOST, an OCaml library for scientific drawing. It is based on METAPOST, which allows inclusion of LTEX fragments. OCaml is an appealing alternative to LTEX macro languages, dedicated languages and even to graphic tools. In particular, MLPOST users benefit from OCaml’s expressiveness and static typing. Finally, MLPOST features a declarative style, which differs from the...
