Do Logical Truths Carry Information?
The paper deals with the question whether logical truth carry information. On the one hand it seems that we gain new information by drawing inferences or arriving at some theorems. On the other hand the formal accounts of information and information content which are most widely known today say that logical truth carry no information at all. The latter is shown by considering these accounts. Th...
متن کاملWhy Do Dolphins Carry Sponges?
Tool use is rare in wild animals, but of widespread interest because of its relationship to animal cognition, social learning and culture. Despite such attention, quantifying the costs and benefits of tool use has been difficult, largely because if tool use occurs, all population members typically exhibit the behavior. In Shark Bay, Australia, only a subset of the bottlenose dolphin population ...
متن کاملHippocampal Activity Patterns Carry Information about Objects in Temporal Context
The hippocampus is critical for human episodic memory, but its role remains controversial. One fundamental question concerns whether the hippocampus represents specific objects or assigns context-dependent representations to objects. Here, we used multivoxel pattern similarity analysis of fMRI data during retrieval of learned object sequences to systematically investigate hippocampal coding of ...
متن کاملCOMMENTARY: Why do pathogens carry avirulence genes?
In the gene-for-gene hypothesis, Flor [19] proposed the existence of avirulence alleles of virulence genes, and that the virulence genes actively conditioned cultivar-specific virulence on hosts. Yet cultivar-specific virulence genes have not been found, and many of the avirulence (ar) genes cloned to date (over 40) do not appear to condition pathogenicity in general, virulence or anything els...
متن کاملExtensions during Software Evolution: Do Objects Meet Their Promise?
As software evolves, data types have to be extended, possibly with new data variants or new operations. It is now folklore that an object-oriented design supports data extensions well, while a functional design seamlessly supports operation extensions. A large body of programming language research has been devoted to the challenge of properly supporting both kinds of extensions. While this chal...
