The impact of the Russia–Ukraine war on stock prices, profits and perceptions in the food supply chain

open access: yesAgribusiness, EarlyView.
Abstract The Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an ...

Tectonic Structure of Alaska as Evidenced by ERTS Imagery and Ongoing Seismicity [PDF]

open access: yes
The author has identified the following significant results. A mosaic was constructed from selected portions of eleven LANDSAT images at a scale of 1:1,000,000. Band 7 images were utilized because of their superior haze-cutting characteristics.

Heterogeneity in Food Price Inflation Convergence Across the EU: Evidence From Club Dynamics and Structural Breaks

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines food price inflation rate convergence among EU27 Member States from 2005 to 2024, focusing on structural breaks, external shocks, and regional disparities. Using panel unit root tests and club convergence analysis, the findings reveal no overall convergence but identify multiple convergence clubs.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Machine Learning‐Enhanced Random Matrix Theory Design for Human Immunodeficiency Virus Vaccine Development

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...

Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

Silicosis, Sarcoidosis, and Silicosarcoidosis Are Overlapping Diagnoses and Difficult to Differentiate

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT We evaluated 12 workers with documented exposure to respirable crystalline silica who were referred to a tertiary care center due to clinical suspicion of silicosis, sarcoidosis, or silicosarcoidosis. Although silica exposure is a well‐established risk factor for silicosis and has been associated with autoimmune diseases, mycobacterial ...

Implementation of First‐Line Rapid Genome Sequencing for Children in Pediatric and Cardiac Intensive Care Units

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Substantial data supports the use of rapid exome and genome sequencing (rES/rGS) in Neonatal Intensive Care Units (NICU), but fewer studies have examined the impact of rES/rGS in other pediatric critical care units. We evaluated the impact on diagnostic yield and time to diagnosis following a single‐center hospital policy change allowing ...
