Species richness-environment relationships of European arthropods at two spatial grains : habitats and countries [PDF]

, 2012
We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy, water-energy dynamics and spatial environmental heterogeneity.

Mitochondrial adaptation decreases drug sensitivity of persistent triple negative breast cancer cells surviving combinatory and sequential chemotherapy

Neoplasia: An International Journal for Oncology Research, 2023
Triple negative breast cancer (TNBC) is an aggressive malignancy for which chemotherapy remains the standard treatment. However, between 3 and 5 years after chemotherapy, about half patients will relapse and it is essential to identify vulnerabilities of

Heterogeneity in structurally arrested hard spheres [PDF]

, 2008
When cooled or compressed sufficiently rapidly, a liquid vitrifies into a glassy amorphous state. Vitrification in a dense liquid is associated with jamming of the particles. For hard spheres, the density and degree of order in the final structure depend

Global Production Increased by Spatial Heterogeneity in a Population Dynamics Model [PDF]

, 2005
Spatial and temporal heterogeneity are often described as important factors having a strong impact on biodiversity. The effect of heterogeneity is in most cases analyzed by the response of biotic interactions such as competition of predation. It may also

Approaches for identifying and measuring heteroresistance in azole-susceptible Candida isolates

Microbiology Spectrum
Heteroresistance to antifungal agents poses a significant challenge in the treatment of fungal infections. Currently, the absence of established methods for detecting and measuring heteroresistance impedes progress in understanding this phenomenon in ...

Generalized voter-like models on heterogeneous networks [PDF]

, 2012
We describe a generalization of the voter model on complex networks that encompasses different sources of degree-related heterogeneity and that is amenable to direct analytical solution by applying the standard methods of heterogeneous mean-field theory.

Polyoxometalate inhibition of SOX2-mediated tamoxifen resistance in breast cancer

Cell Communication and Signaling
Background Increased cancer stem cell (CSC) content and SOX2 overexpression are common features in the development of resistance to therapy in hormone-dependent breast cancer, which remains an important clinical challenge. SOX2 has potential as biomarker
