Conformal invariants from nodal sets. I. Negative Eigenvalues and Curvature Prescription [PDF]

open access: yes, 2012
In this paper, we study conformal invariants that arise from nodal sets and negative eigenvalues of conformally covariant operators; more specifically, the GJMS operators, which include the Yamabe and Paneitz operators.

The amount of reachable habitat determines population fate

open access: yesEcography, Volume 2026, Issue 1, January 2026.
The scientific community remains divided on the most effective way to design landscapes for biodiversity conservation or restoration. Although there is a consensus that habitat loss is the main cause of biodiversity decline worldwide, the extent to which fragmentation (i.e.

La construcción del sujeto lírico en la poética 'objetual' de Francis Ponge [PDF]

open access: yes, 2013
El propósito de este trabajo es el de mostrar, a partir del caso de la obra de Francis Ponge, cómo el sujeto lírico de una producción deliberadamente no subjetivista puede construirse, precisamente, ante la ausencia de ese sujeto y por oposición al ...

The sectorial projection defined from logarithms

open access: yes, 2011
For a classical elliptic pseudodifferential operator P of order m>0 on a closed manifold X, such that the eigenvalues of the principal symbol p_m(x,\xi) have arguments in \,]\theta,\phi [\, and \,]\phi, \theta +2\pi ...

The humus profile of an alpine ericaceous heath (Savoie, France): A high‐resolution micromorphological analysis

open access: yesSoil Science Society of America Journal, Volume 89, Issue 5, September/October 2025.
Abstract The characteristics used to distinguish between Mor and Moder differ among the various classifications of humus forms. Mor is often associated with ericaceous heathland that develops at high altitude or latitude, or in lowlands when soils are nutrient‐poor, sandy, and acidic.

Tree species and soil depth affect microbial necromass contribution to soil organic matter in temperate forest soils, surpassing the impact of microbial and faunal community composition

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2219-2233, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forest management and climate change inevitably lead to shifts in the composition of temperate forest stands from coniferous to deciduous species, potentially affecting the crucial role of forest soil organic carbon (SOC) stocks in mitigating climate change.

Spectral Asymmetry, Zeta Functions and the Noncommutative Residue

open access: yes, 2006
In this paper we study the spectral asymmetry of (possibly nonselfadjoint) elliptic PsiDO's in terms of the difference of zeta functions coming from different cuttings. Refining previous formulas of Wodzicki in the case of odd class elliptic PsiDO's, our

Genome Wide Analyses Corroborate Cryptic Speciation in Anurida maritima (Collembola, Poduromorpha)

open access: yesZoologica Scripta, Volume 54, Issue 5, Page 649-657, September 2025.
ABSTRACT Cryptic diversity is ubiquitous within Collembola (springtails). Numerous studies have reported substantial genetic divergence within morphological species. One potentially involved morphospecies is Anurida maritima (Guérin‐Méneville, 1836). A. maritima is confined to the intertidal zone, where it often occurs in high densities. A recent study
