Snow microinvertebrates from lowlands, high mountains and the Arctic—implications for conservation efforts

Abstract The protection of cryospheric ecosystems and their biota cannot be properly defined without a detailed species inventory. Snow microinvertebrates are crucial for estimating cryophilic biodiversity, yet they are poorly described at broader spatial scales. To fill this kno...

Pressure-Induced Transitions in the Friction and Wear of Self-Lubricating PEO-Graphite Coatings for Magnesium-Polymer Sliding

This study investigates the influence of nominal contact pressure on the tribological behaviour of oxide coatings produced by plasma electrolytic oxidation (PEO) on AZ31B magnesium alloy and subsequently modified with graphite. While the effects of composition are well documented...

Differential expression of TGF-β1, TGF-β2, and TGF-β3 across WHO grades in meningioma: convergent evidence from mRNA, methylation, miRNA, and protein analysis

Meningiomas show biological heterogeneity not captured by WHO grading alone. TGF-β signaling has been implicated in meningioma pathobiology, yet a systematic, grade-stratified, isoform-resolved characterization of TGF-β1, TGF-β2, and TGF-β3 across transcriptional, epigenetic, pos...

Physical workload and task efficiency across four mannequin towing techniques in water rescue

Direct in-water rescue is a safety-critical task in which towing technique and rescue-support equipment may influence both rescuer workload and task output. This study compared physical workload, towing performance and physiological economy across four mannequin towing techniques...

Partial to Complete Decoupling of Th-U-Pb Ages, Chemical Domains, and Monazite-Xenotime Immiscibility Gap Thermometry in Orthogneiss Monazite (Khanom Core Complex, Southern Thailand)

Abstract We investigate the relationships between monazite Th-U-Pb ages, chemical domains, and monazite-xenotime immiscibility gap thermometry from two Indosinian orthogneisses from the Khanom Core Complex (Southern Thailand), with the aim of better understanding the relationship...

Geographies in flux - how time and location influence shrinking medium-sized cities

Urban shrinkage has emerged as a significant challenge across Europe, particularly for medium-sized cities (MSCs) with populations between 20,000 and 100,000. While previous research has largely focused on demographic decline in large cities, the spatial and institutional dynamic...

Direct evidence for scavenging as a primary feeding strategy in Pliocrocuta, an extinct genus of bone-cracking hyaenas

Abstract The carnivoran family Hyaenidae exhibits a complex evolutionary history of diverse trophic adaptations, including the consumption of almost entire carcasses, either predated or scavenged. The associated durophagy peaked within the subfamily Hyaeninae in a clade of ‘fully...

Barium gallo-germanate glasses co-activated with Cr3+/Er3+ and Cr3+/Er3+/Ln3+ (Ln = Yb, Ho) for near-infrared luminescence applications

Abstract Near-infrared luminescence properties of barium gallo-germanate glasses co-activated with Cr 3+ /Er 3+ and Cr 3+ /Er 3+ /Ln 3+ (Ln = Yb, Ho) have been studied for the first time. Compared to Cr 3+ /Er 3+ co-doped sample, near-infrared emission of Er 3+ at 1534 nm in Cr 3...

Selected clinical parameters of cardiology patients, their health-promoting behaviors and quality of life in relation to body mass index

Taking into account the significant role of weight disorders and various preventive measures in maintaining human health, as well as the ever-increasing importance of assessing quality of life during the therapeutic process, an interesting research area seems to be analyses compa...

Stand Age, Standard Retention Density and Site Conditions as Drivers of Shoot Biomass Accumulation in Mediterranean Oak Coppices

ABSTRACT Mediterranean oak coppices represent an important fuelwood resource in Central Italy, but management decisions are often constrained by limited quantitative evidence on the relative importance of stand development, standard retention, site conditions, and climate in driv...
