Efficient Algorithms for Membership in Boolean Hierarchies of Regular Languages [PDF]
, 2007 The purpose of this paper is to provide efficient algorithms that decide membership for classes of several Boolean hierarchies for which efficiency (or even decidability) were previously not known. We develop new forbidden-chain characterizations for the

Hierarchy-Aware Global Model for Hierarchical Text Classification
Annual Meeting of the Association for Computational Linguistics, 2020 Hierarchical text classification is an essential yet challenging subtask of multi-label text classification with a taxonomic hierarchy. Existing methods have difficulties in modeling the hierarchical label structure in a global view.

, 2005 We study a recently proposed mechanism to solve the hierarchy problem in the context of the landscape, where the solution of the hierarchy problem is connected to the requirement of having baryons in our universe via Electroweak Baryogenesis.

A new extended matrix KP hierarchy and its solutions
, 2010 With the square eigenfunctions symmetry constraint, we introduce a new extended matrix KP hierarchy and its Lax representation from the matrix KP hierarchy by adding a new $\tau_B$ flow.

Time to challenge the spurious hierarchy of systematic over narrative reviews?
European Journal of Clinical Investigation, 2018 Systematic reviews are generally placed above narrative reviews in an assumed hierarchy of secondary research evidence. We argue that systematic reviews and narrative reviews serve different purposes and should be viewed as complementary.

‘Hierarchy’ in the organization of brain networks
Philosophical Transactions of the Royal Society of London. Biological Sciences, 2020 Concepts shape the interpretation of facts. One of the most popular concepts in systems neuroscience is that of ‘hierarchy’. However, this concept has been interpreted in many different ways, which are not well aligned. This observation suggests that the
