Antioxidant activity recorded by endogenous fluorescence monitoring in green microalga Chlorella sp. exposed to chosen antioxidants

Abstract Algae represent a biotechnologically important group of organisms whose physiological processes can be studied using endogenous fluorescence. This study tested fluorescence methods for evaluating the effect of antioxidants on the algae Chlorella sp. using endogenous fluo...

Lowering Coordination Symmetry as a Strategy for Tuning Slow Magnetic Relaxation in Quasi-Isotropic Mn(II) Systems

Abstract Two pentacoordinate Mn(II) complexes containing tridentate 2.2′-[oxybis(methylene)] bis(1H-1,3-benzimidazole) (OMeBB) ligand and pseudohalide coligands, [Mn(OMeBB)(NCS)2] (1) and [Mn(OMeBB)(NCO)2] (2), exhibit a very rare {MnIIN4O} coordination mode involving semicoordin...

Raman Spectroscopic Characterization of the Benzene:Acetonitrile (3:1) Cocrystal Relevant to Titan, Saturn’s Moon

Abstract Titan, Saturn’s largest moon, hosts active organic chemistry and surface environments where small molecules are expected to crystallize as molecular minerals. Benzene and acetonitrile, both predicted to be present on Titan, were shown to form a thermodynamically stable b...

Prevalence of Pelvic Girdle Pain in Postpartum Women in Slovakia: A Cross-sectional Study

Pelvic girdle pain (PGP) is a prevalent condition during the postpartum period that significantly affects functional mobility and quality of life. The aim of this study was to determine the prevalence of PGP among postpartum women in Slovakia (12 weeks to 1 year postpartum) and t...

Adoption and Automation Risk of AI Tools in Public and Private Enterprises: A Machine Learning-Based Analysis

Artificial intelligence (AI) is transforming enterprises globally, introducing new efficiencies while raising concerns about workforce automation. This study investigates AI tool adoption and potential automation risks in public and private sectors using data collected from 477 r...

Variable high-contrast all-optical self-switching of femtosecond solitonic pulses in multi-dual-core optical fiber with distributed optical asymmetry

Abstract Effective alloptical selfswitching of Cband femtosecond pulses, driven by pulse energy in a nonlinear fiber coupler, was experimentally investigated. A key contribution of this work is the detailed analysis of optical asymmetry between the two fiber cores influencing the...

Double Jeopardy in digital entertainment: a preregistered movie-level replication with an exploratory franchise extension using MovieLens 32M

Abstract This paper revisits the Double Jeopardy (DJ) regularity in digital entertainment using the public MovieLens 32M archive. DJ predicts that brands with higher penetration also have slightly higher loyalty. We first run a preregistered test at the movie level, treating each...

Carbapenem-Resistant Klebsiella pneumoniae Producing Single or Dual Carbapenemases and Emergence of ST395 Strains Co-harbouring NDM-5 and OXA-232 in Selected University Hospitals

Abstract Background Emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP) strains poses a serious global threat, driven by expansion of high-risk clones producing dual carbapenemases and exhibiting increased antimicrobial resistance. Materials and methods We investigated...
