Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers

Automated segmentation using computer vision applied to petrographic thin sections of unconventional tight gas sandstone reservoirs

open access: yesDiscover Geoscience
In the recent years, there have been numerous attempts to quantify the porosity of sandstones by different computational algorithms, and to a lesser extent to identify minerals in petrographic thin sections using diverse techniques. This is a challenging

Bank Monitoring with On‐Site Inspections

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT Using proprietary transaction‐level data on nonsyndicated construction loans, we provide some of the first empirical evidence on the drivers and consequences of bank monitoring through on‐site inspections. Banks trade off monitoring intensity with favorable origination terms.

Direct Observation of Electric‐Field‐Driven Phase Transitions Associated with Energy Storage in Antiferroelectric Films

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
The electric‐field‐driven antiferroelectric‐to‐ferroelectric phase transition in epitaxial PbZrO3 films is directly visualized by in situ aberration‐corrected scanning transmission electron microscopy. A sequential transition pathway involving an orthorhombic ferrielectric phase and a monoclinic ferroelectric phase, ultimately stabilizing into a ...

Assessment of Biological Contribution to Natural Recovery of Anthropized Freshwater Sediments From Argentina: Autochthonous Microbiome Structure and Functional Prediction

open access: yesFrontiers in Microbiology, 2021
Monitored natural recovery (MNR) is an in situ technique of conventional remediation for the treatment of contaminated sediments that relies on natural processes to reduce the bioavailability or toxicity of contaminants.

Seismic Waves Do Sense Fracture Connectivity: Experimental Validation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Fracture connectivity is a key parameter controlling fluid flow throughout the Earth's crust. While some theoretical and numerical studies suggest that seismic waves are sensitive to fracture connectivity, an experimental validation of this critically important phenomenon was so far unavailable.

A mollified Ensemble Kalman filter

open access: yes, 2010
It is well recognized that discontinuous analysis increments of sequential data assimilation systems, such as ensemble Kalman filters, might lead to spurious high frequency adjustment processes in the model dynamics.

Carbon dioxide concentration in Mediterranean greenhouses : how much lost production? [PDF]

open access: yes, 2007
In the absence of artificial supply of carbon dioxide in the greenhouse environment, the CO2 absorbed in the process of photosynthesis must ultimately come from the external ambient through the ventilation openings.

Nap1L4a Cooperates with Scl/Klf1 to Recruit H2A.Z in Mediating Interactions Among Cis‐Regulatory Elements and Transcription Required for Primitive Erythropoiesis in Zebrafish

open access: yesAdvanced Science, Volume 13, Issue 12, 27 February 2026.
Nap1l4a is required in erythropoiesis and hypoxia responses via physical interaction with Klf1 and Scl to recruit the histone variant H2A.Z. This facilitates its associated cis‐regulatory element (CRE) remodeling and the consequent chromatin assembly, and activates the transcription of erythroid lineage‐specific genes.
