We propose ‘Dracula’, a new framework for unsupervised feature selection from sequential data such as text. Dracula learns a dictionary of n-grams that efficiently compresses a given corpus and recursively compresses its own dictionary; in effect, Dracula is a ‘deep’ extension of Compressive Feature Learning. It requires solving a binary linear program that may be relaxed to a linear program. B...

Danionella dracula is a new species of sexually dimorphic, miniature and highly developmentally truncated cyprinid fish. Compared with its close relative, the zebrafish Danio rerio, it lacks 44 bones or parts thereof and represents one of the most developmentally truncated vertebrates. Absence of the majority of bones appears to be due to developmental truncation via terminal deletion. In contr...

Mimicry, like coral snakes and their nonvenomous imposters, is one of the most compelling examples of evolution by natural selection. Although mostly known from animals that gain protection by resembling an unpalatable or harmful compatriot, both types of mimicry, Müllerian and Batesian, also occur in plants and fungi. Some fungi are known to mimic flowers to dupe pollinators into vectoring spo...

Throughout the ages, literary works have expressed fears and expectations generated by scientific discoveries and have portrayed images and myths about science itself. Several parameters can contribute to these representations of science, including the culture and social class to which the authors of these works belong. We also cannot deny the influence of gender, as due to the fact that the ma...
