Life Cycle Assessment of Polylactic Acid/Brewer’s Spent Grain Biocomposites: Environmental Impact of Lignocellulosic Waste Incorporation

The environmental burden of conventional plastic packaging has increased interest in sustainable alternatives. This study evaluates the environmental performance of polylactic acid (PLA) biocomposites reinforced with brewer’s spent grain (BSG), an agro-industrial by-product, usin...

Exogenous L-Citrulline Increases Tolerance to Tomato Brown Rugose Fruit Virus in Tomato Plants

Tomato brown rugose fruit virus (ToBRFV) is one of the most aggressive viral pathogens affecting commercial tomato cultivars, causing severe economic losses worldwide. Since plant viral diseases cannot be effectively controlled with pesticides, alternative strategies aimed at red...

Modular Classes and Supersymmetric Berezin Volumes

We argue that modular classes of \(Q\)-manifolds provide an efficient method for addressing the existence of supersymmetric Berezin volumes in the supergeometric representation theory of the \(\mathcal {N}=2\) \(d=1\) supertranslation algebra. We establish a cohomological coheren...

Balanced domination in convex polytopes, trees, and grid graphs

This paper addresses two open questions posed in Xu et al. (2021) regarding the balanced domination number in graphs. We show that three new classes of graphs—those of convex polytopes A n , D n , and R n ′ ′ —are d -balanced. Further, we provide a characterization of d -balanced...

Whispered Speech Recognition Enhancement Using Teager Energy Operator with PLP Features

Abstract Whispered speech poses persistent challenges for automatic speech recognition (ASR) owing to the absence of vocal fold vibration and the dominance of turbulent airflow excitation, which substantially alters spectral and temporal energy distributions. Conventional front-e...

Cigarette Affordability and Consumption in Bosnia and Herzegovina, 2010–2023: Implications for Tobacco Tax Policy

Abstract Background Tobacco taxation effectively reduces cigarette consumption, but its success depends on whether price increases outpace income growth. In Bosnia and Herzegovina, rising incomes and stagnating excise taxes after 2019 have increased cigarette affordability. Metho...

Beyond Pain Intensity: Central Sensitization and Psychosocial Symptom Burden in Women with Rheumatoid Arthritis

Background and Objectives: Persistent pain in rheumatoid arthritis (RA) may reflect mechanisms not fully captured by systemic inflammatory markers. This study estimated the frequency of elevated Central Sensitization Inventory (CSI) scores in women with RA and examined associatio...

Towards resilient forest establishment in Europe: functional traits, genetic diversity and multifunctional design

Abstract Forest restoration and afforestation across Europe are accelerating, yet the decision-making processes governing forest establishment remain unevenly examined, especially from a biodiversity perspective. Considering this and the global environmental changes of climate sh...

Lean Six Sigma DMAIC framework in consumer finance: linking payment flexibility to financial literacy and payment trust

Purpose This study aims to operationalise the Lean Six Sigma (LSS) DMAIC framework as the overarching methodological logic for examining the relationships among payment trust (PT), financial literacy (FL) and payment flexibility (PF). Specifically, it investigates the direct rela...
