Silt-sized sediments and gypsum on surface formations in the Ebro Basin: a disambiguation of the term “gypsiferous silts”

open access: yesGeologica Acta, 2021
The term “gypsiferous silts” has been used since the 1960s by many authors, but it has relied on unclear, am-biguous criteria that attributed aeolian, colluvial or alluvial origins to these materials.

Gap Analysis of Ambient Electromagnetic Noise Measurements Stored in the ITU Data Banks

open access: yesSensors
For any radio frequency (RF) sensor (receiver) to function optimally, the ambient noise field strength, converted to electrical power by the transducer (antenna), must be lower than the in-ternal noise of that sensor. Therefore, knowledge of the expected

Microclimate Refugia: Comparing Modeled to Empirical Near-Surface Temperatures on Rangeland

open access: yesGeographies, 2023
Microhabitats can provide thermal niches that affect geographic range shifts of species as the climate changes and provide refuges for pest and beneficial insect populations in agricultural regions. The spatial distribution of microhabitats is influenced

On the Distributability of Mobile Ambients [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2018
Modern society is dependent on distributed software systems and to verify them different modelling languages such as mobile ambients were developed. To analyse the quality of mobile ambients as a good foundational model for distributed computation, we analyse the level of synchronisation between distributed components that they can express.

Stability and performance comparison of capillary-assisted vitrification and lyophilization for probe qPCR master mixes

open access: yesAAPS Open
Recent advancements in freeze-drying (lyophilization) have led to the creation of lyophilized PCR mixes. The lyophilized cake or bead offers benefits compared to liquid formulations including extended shelf lives and room-temperature storage, but they ...

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Paisatge i medi ambient: una distinció conceptual

open access: yesEnrahonar: Quaderns de Filosofia, 2014
En aquest article es mostra que el concepte de medi ambient, quan es pren com a categoria principal d’una visió del món que busca reconèixer, valorar i protegir els espais naturals, condueix inevitablement a conseqüències contradictòries: d’una banda ...
