Given a 4-tuple of Boolean variables (a, b, c, d), logical proportions are modeled by a pair of equivalences relating similarity indicators (a∧ b and a ∧ b), or dissimilarity indicators (a ∧ b and a ∧ b) pertaining to the pair (a, b), to the ones associated with the pair (c, d). There are 120 semantically distinct logical proportions. One of them models the analogical proportion which correspon...

IN THE PERPETUALLY RESOURCE-STARVED environment of public health, where each disease or risk factor has to fight for a scrap of the federal budget, it is easy to forget how fast progress can be made when appropriate policy attention and resources are marshaled to solve a problem. The natural response of public health professionals to the starvation diet is to maintain low expectations. But thos...

INTRODUCTION An attractive facial appearance is considered nowadays to be a decisive factor in establishing successful interactions between humans. In relation to this topic, scientific literature states that some of the facial features have more impact then others, and important authors revealed that certain proportions between different anthropometrical landmarks are mandatory for an attracti...

China is experiencing a syphilis epidemic of enormous proportions. The regions most heavily affected by syphilis correspond to regions where sexually transmitted HIV infection is also a major public health threat. Many high-risk patients in China fail to receive routine syphilis screening. This missed public health opportunity stems from both a failure of many high-risk individuals to seek clin...

Analogies play an important role in many reasoning tasks. In this paper, we survey a recently proposed modeling for an analogical proportion, i.e. a statement of the form “A is to B as C is to D”, and its diverse applications. The logical representation used for encoding such proportions takes both into account what the four situations have in common and how they differ. Thanks to the use of a ...

Application of the Next generation sequencing (NGS) technology has demonstrated that most tumor samples exhibit intra-tumor heterogeneity. Here we proposed SAPPH (Somatic Aberrations Prediction for Paired Heterogeneous tumor samples), as a new method for estimating tumor somatic copy number aberrations as well as inferring tumor subclone proportions from heterogeneous tumor sequencing data. Thi...
