Covariant singularities in quantum field theory and quantum gravity

open access: yesNuclear Physics B, 2021
It is rather well-known that spacetime singularities are not covariant under field redefinitions. A manifestly covariant approach to singularities in classical gravity was proposed in [1].

Mining Candidate Genes and Favorable Haplotypes for Flag Leaf Shape in Rice (Oryza sativa L.) Based on a Genome-Wide Association Study

open access: yesAgronomy, 2022
The shape of the rice flag leaf affects rice yield. Therefore, the detection of quantitative trait loci (QTLs) and alleles related to rice flag leaf shape is of great significance for rice yield improvement.

Flag area measures

open access: yes, 2019
A flag area measure on an $n$-dimensional euclidean vector space is a continuous translation-invariant valuation with values in the space of signed measures on the flag manifold consisting of a unit vector $v$ and a $(p+1)$-dimensional linear subspace ...

Projected Richardson varieties and affine Schubert varieties [PDF]

open access: yes, 2015
Let $G$ be a complex quasi-simple algebraic group and $G/P$ be a partial flag variety. The projections of Richardson varieties from the full flag variety form a stratification of $G/P$.

Les crimes et châtiments emblématiques à travers l’exemple du drapeau médiéval

open access: yesCriminocorpus, 2020
Medieval sources often mentioned violence against flags, in a military context or not: these practices can be explained by the importance attached by medieval justice to visual elements in the exercise of punishment.

Generalized angle vectors, geometric lattices, and flag-angles

open access: yes, 2021
Interior and exterior angle vectors of polytopes capture curvature information at faces of all dimensions and can be seen as metric variants of $f$-vectors.

Proposed improvement of coastal habitat resilience: The case study of Pantano forest of Policoro in southern Italy

open access: yesFrontiers in Marine Science, 2022
In the last decades, climate change and the rapid urbanization due to the development of the coastal economy have led to biodiversity loss and the fragmentation of habitat in many coastal zones. The presence of protected areas cannot prevent the progress
