ANOTHER LOOK AT THE ESTIMATION OF DYNAMIC PROGRAMMING MODELS WITH CENSORED DECISION VARIABLES [PDF]

open access: yes
In this paper we propose a new approach to estimate the structural parameters in the context of a censored continuous decision model. Instead of handling with the original model, we consider an approximate model in which the decision variable has been ...

Pangenome of Acinetobacter baumannii uncovers two groups of genomes, one of them with genes involved in CRISPR/Cas defence systems associated with the absence of plasmids and exclusive genes for biofilm formation

open access: yesMicrobial Genomics, 2019
Acinetobacter baumannii is an opportunistic bacterium that causes hospital-acquired infections with a high mortality and morbidity, since there are strains resistant to virtually any kind of antibiotic. The chase to find novel strategies to fight against

The Fate of Iron Formations in the Deep Mantle: Constraints From Iron Oxide Reduction Kinetics Experiments

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dense sedimentary iron formations (IFs) subducted into the mantle during Earth's early history, may have descended to the core‐mantle boundary where they could exert strong control on its thermal and seismological properties. A key unanswered question is the extent to which IFs retain their oxidized character in the much more reducing mantle ...

Radon‐222 as an Effective Tracer to Distinguish Groundwater Circulation Patterns in the Deep Fault‐Controlled Geothermal System

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Groundwater flow regulated by deep faults remains challenging to trace due to structural complexity. This study applies the noble gas tracer 222Rn combined with hydrochemistry and stable isotopes (δ2H, δ18O) to distinguish circulation patterns of geothermal springs along a major fault in the Tibetan Plateau.

Social perception, market potential, and ecosystem services valuation of Mediterranean regenerative citrus systems

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Mediterranean agricultural systems face increasing environmental pressures, including water scarcity, climate variability, and land degradation. Regenerative agriculture has been proposed to enhance sustainability in citrus systems, but its adoption depends on social acceptance and market viability.
