Pore density of the benthic foraminiferal test responded to the hypoxia off the Changjiang estuary in the East China Sea

open access: yesFrontiers in Marine Science, 2023
The benthic foraminiferal assemblages are commonly used to indicate different oxygenation conditions. In the last few decades, pore characteristics of the benthic foraminiferal tests from the micro-perspective using high-spatial-resolution analysis have ...

Generating Unobserved Alternatives

open access: yesCoRR, 2020
We consider problems where multiple predictions can be considered correct, but only one of them is given as supervision. This setting differs from both the regression and class-conditional generative modelling settings: in the former, there is a unique observed output for each input, which is provided as supervision; in the latter, there are many ...

A Generalization of Alternating Sign Matrices [PDF]

open access: yesJournal of Combinatorial Designs, 2014
AbstractIn alternating sign matrices, the first and last nonzero entry in each row and column is specified to be +1. Such matrices always exist. We investigate a generalization by specifying independently the sign of the first and last nonzero entry in each row and column to be either a +1 or a −1.

When double is not twice as much

open access: yesFrontiers in Plant Science, 2011
Gene and genome duplications provide a playground for various selective pressures and contribute significantly to genome complexity. It is assumed that the genomes of all major eukaryotic lineages possess duplicated regions that result from gene and ...
