Do state borders constrain internal mobility? Evidence from Brazil

This paper documents that state borders are a meaningful source of friction in internal labour mobility in Brazil, a large emerging economy with substantial labour-market informality and historically heterogeneous borders. Using geocoded municipality-to-municipality migration and...

Impact of chronic doxycycline treatment in a mouse model of tauopathy

Tauopathies are neurodegenerative disorders characterized by the accumulation of hyperphosphorylated tau, leading to synaptic dysfunction, neuroinflammation, and both cognitive and motor impairments. Doxycycline (Doxy), a tetracycline antibiotic commonly used to treat bacterial i...

Agricultura Familiar y Agroindustrias: subordinación productiva. Los casos de la citricultura y la fruticultura de Argentina (2003-2016)

This article proposes to investigate the link between family farming (AF) and agro-industries. The research is based on a qualitative methodology and uses quantitative information. In particular, two cases (citric belt of Middle Uruguay River and fruit growing of Patagonic Valley...

Transcriptome derived microsatellite markers in Valeriana clarionifolia reveal transferability among Patagonian Valeriana species

Abstract Several species within the genus Valeriana are globally recognized for their medicinal properties. However, their increasing economic value has led to overharvesting of natural populations, posing a serious threat to their long-term sustainability. Effective strategies f...

Pollinator behaviour and morphology to understand pollination niche partitioning in co‐occurring closely related plant species

Abstract Pollinator foraging behaviour shapes a plant's pollination niche, with direct consequences for natural selection and plant evolution. However, the extent to which individual‐ and species‐level pollinator behaviour, and the drivers of such behaviour, actually influence po...

Process mapping of a collaborative quality improvement study to optimise the use of antibiotics in intensive care units in Argentina: a Pathfinder study

<ns5:p>Objective To systematically document the operational components, barriers, facilitators, and solutions of a quality improvement collaborative for antibiotic stewardship in intensive care units (ICUs) in the public sector of Argentina, using the Pathfinder methodological fr...

Early-life exposure to plastics is associated with health parameters and biomarkers in southern giant petrels

The sub-lethal effects of plastics and their associated chemicals on wildlife are poorly understood, primarily due to the lack of reliable indicators. We used southern giant petrels ( Macronectes giganteus, SGP), key scavengers and predators in southern seas, to assess whether ea...

Efficient Techniques for Low-Rank Tensor Approximation and Applications in Robust Object Detection

This paper introduces efficient randomized fixed-precision and single-pass algorithms for low-tubal-rank approximation of third-order tensors. The proposed fixed-precision algorithms are faster and more efficient than the existing algorithms for approximating the truncated tensor...

Environmental associations and spatial segregation among coexisting Pogonomyrmex harvester ant species in the central Monte desert (Argentina)

Abstract Background Ant communities are widely considered to be structured by interspecific competition. Seed-harvesting ants are dominant granivores in drylands, and their colony locations influence their spatio-temporal effect on plant communities. Three closely related species...

Differential Responses for Emotional Visual and Auditory Word Recognition in First vs. Second Language

Aims: This study explored how valence and modality affect emotional word recognition in unbalanced Spanish-English bilinguals. Design: Two lexical decision tasks were used: a visual task (Study 1) and an auditory task (Study 2), conducted in either L1 or L2. Data and Analysis: Da...

A pair of duplicated SOC1 genes, DcSOC1-1 and DcSOC1-2, control vernalization requirement in carrot

Abstract Background Carrot vernalization requirement (VR), the amount of cold exposure needed for plants to become vernalized, strongly influences geographical adaptation of the crop and many agricultural practices, and this trait defines annual vs. biennial cultivars. Despite it...

Expected redshift drift for tilted observers

Abstract Redshift drift is usually discussed for observers comoving with the cosmological background, but realistic observations are made by observers with nonzero peculiar motion. In this work, we calculate the expected redshift drift for tilted observers within the covariant 1...

eDNA Metabarcoding Reveals Spatial Patterns of Marine Communities Along the Beagle Channel (Tierra del Fuego, Argentina)

The Beagle Channel, located south of Tierra del Fuego (~54° S), is South America’s southernmost intracoastal ecosystem. Here, we applied environmental DNA metabarcoding using a partial sequence of the 12sRNA mitochondrial gene to evaluate the seasonal and spatial dynamics of mari...

FGFR3-driven gene regulatory network analysis reveals a protumoral role for p63 in luminal bladder tumors

Fibroblast growth factor receptor 3 ( FGFR3 ) is one of the most frequently altered genes in bladder cancer, primarily through activating mutations that drive oncogenesis and are enriched in luminal tumors. However, the underlying gene regulatory network (GRN) remains poorly char...
