Machine learning methods for landslide mapping studies: A comparative study of SVM and RF algorithms in the Oued Aoulai watershed (Morocco)

Abstract Effective management of watershed risks and landslides necessitates comprehensive landslide susceptibility mapping. Support vector machine (SVM) and random forest (RF) machine learning models were used to map the landslide susceptibility in Morocco’s Taounate Province. Detailed landslide inventory maps were generated based on aerial pictures, field research, and geotechnical survey reports. Factor correlation analysis carefully eliminated redundant factors from the original...

Fungal Pathogens Associated with Tomicus Species in European Forests: Regional Variations and Impacts on Forest Health

Pinus species are extensively abundant in Europe and, as pioneer trees, prominently influence local ecology. However, pine forests in Lithuania, Montenegro, and Ukraine have been significantly damaged by pine bark beetles (Tomicus sp.), which are closely associated with ophiostomatoid and other pathogenic fungi. This study aimed to identify the diversity of ophiostomatoid and other fungi associated with Tomicus sp. in these three countries. Fungi were isolated from beetles and identified. High-throughput...

Exploring the Potential of Posidonia oceanica Fibers in Eco-Friendly Composite Materials: A Review

The growing demand for sustainable materials has driven the exploration of natural fibers as eco-friendly alternatives to synthetic reinforcements for composites. This study investigates the potential of Posidonia oceanica, an abundant marine biomass, which is often driven to be stacked on the backshore and used so far for energy recovery and low-value applications, as a filler and possible reinforcement in cementitious and polymer composites. Most applications of Posidonia are concentrated in the...

New Evidence for the Contemporary Presence of Juvenile White Sharks (Carcharodon carcharias) in the Adriatic Sea

The presence of the white shark (Carcharodon carcharias) in the Mediterranean Sea is well documented, but mainly through historical and opportunistic records. Historically, the Adriatic Sea, particularly its eastern coastline, was considered a hotspot for white sharks, with relatively frequent reports of juvenile specimens suggesting a potential nursery area. However, since the second half of the 20th century, the abundance of white sharks in the Adriatic has experienced a dramatic decline, with...

GIS-Based Spatial Modeling of Soil Erosion and Wildfire Susceptibility Using VIIRS and Sentinel-2 Data: A Case Study of Šar Mountains National Park, Serbia

Soil erosion and wildfires are frequent natural disasters that threaten the environment. Identifying and zoning susceptible areas are crucial for the implementation of preventive measures. The Šar Mountains are a national park with rich biodiversity and various climate zones. Therefore, in addition to protecting the local population from natural disasters, special attention must be given to preserving plant and animal species and their habitats. The first step in this study involved collecting and...

Expression Analysis of Circulating miR-21, miR-34a and miR-122 and Redox Status Markers in Metabolic Dysfunction-Associated Steatotic Liver Disease Patients with and Without Type 2 Diabetes

Metabolic dysfunction-associated steatotic liver disease (MASLD), a hepatic form of metabolic syndrome, often co-occurs with type 2 diabetes (T2D) and now affects approximately 30% of the global population. MASLD encompasses conditions from simple steatosis to metabolic dysfunction-associated steatohepatitis, with oxidative stress (OS) driving progression through inflammation. This study analyzes the expression levels of circulating miRNAs and redox status markers in MASLD patients with and without...

A condition equivalent to the Hölder continuity of harmonic functions on unbounded Lipschitz domains

Our main result concerns the behavior of bounded harmonic functions on a domain in [Formula: see text] which may be represented as a strict epigraph of a Lipschitz function on [Formula: see text]. Generally speaking, the result says that the Hölder continuity of a harmonic function on such a domain is equivalent to the uniform Hölder continuity along the straight lines determined by the vector [Formula: see text], where [Formula: see text] is the base of standard vectors in [Formula: see text]....

Water mite diversity from southwestern Türkiye through the lens of the DNA barcodes, with the description of one new species (Acari, Hydrachnidia)

This study presents the molecular and morphological results from an analysis of water mites collected in southwestern Türkiye. 83 COI barcodes are provided, clustered into 40 BINs, with 23 BINs being unique and deposited for the first time in the Barcode of Life Data Systems (BOLD). The first DNA barcodes for eight water mite species are uploaded into the BOLD database. In total, 34 water mite species were identified and one of them, Iranothyas marismortui (Gerecke, 1999) is newly reported from...

Uncoupling of General Linear Multi-degree-of-freedom Structural and Mechanical Systems Through Quasi-diagonalization

Abstract This paper develops a fundamental result in linear algebra by providing the necessary and sufficient conditions for the simultaneous quasi-diagonalization of two symmetric matrices and two skew-symmetric matrices by a real orthogonal congruence. This result is used to study the uncoupling of general linear multi-degree-of-freedom (MDOF) structural and mechanical systems described by arbitrary damping and stiffness matrices through quasi-diagonalization, and real orthogonal...

Phenolic Content and Antioxidant Potential of Wine Extracts

Background/Objective: Phenolic compounds are considered to be the most important parameters of wine quality, contributing not only to its organoleptic characteristics, but to various health benefits associated with wine consumption. Although these are successfully extracted from grapes and winemaking by-products, there is no data on extraction from wine itself. This is particularly interesting in light of the fact that the variability of wine polyphenols is not only attributed...
