How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.

Brauer algebra of type F4

open access: yes, 2012
We present an algebra related to the Coxeter group of type F4 which can be viewed as the Brauer algebra of type F4 and is obtained as a subalgebra of the Brauer algebra of type E6.

Supervised Protein Structure Classification Using Topological Persistence With DeltaFold

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Recent advances in protein structure prediction have considerably increased the number of available structures, underscoring the need for scalable and accurate methods to compare and classify this huge amount of data. Current approaches based on sequence alignment or structural superposition often lack sensitivity and/or are computationally ...

A BV-algebra structure on Hochschild cohomology of the integral group ring of finitely generated Abelian groups

open access: yes
We study a Batalin-Vilkovisky algebra structure on the Hochschild cohomology of the group ring of finitely generated abelian groups. The Batalin-Vilkovisky algebra structure for finite abelian groups comes from the fact that the group ring of finite ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

open access: yesPackaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

New views of some invariants associated with the Cartesian 2D velocity gradient tensor

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Vorticity and divergence of horizontal flow are fundamental quantities in meteorology; both are linear functions of the four elements of the 2D velocity gradient tensor and both are formally unchanged under coordinate rotation. We explore four quadratic functions of the elements that are geometrically invariant in this sense, finding some novel ...

A verified algebra for read-write linked data

open access: yes
The aim of this work is to verify an algebra for high level languages for reading and writing Linked Data. Linked Data refers to a collection of standards which aim to enhance the world’s data, by interlinking datasets through the Web. The starting point
