Fractional q-Starlikeness in Mittag–Leffler and Limaçon Domains

In this paper, we use a normalized fractional q-derivative operator, constructed by combining Jackson’s q-difference operator with a fractional q-integral, to introduce two subclasses of normalized analytic functions in the open unit disk whose fractional transforms are starlike...

Black Hole Plunging into a Quasar Disk: Standard Infinity vs. Zero-Less Finite Burst

Standard physics predicts that when a black hole plunges into a quasar's accretion disk, the central singularity at r = 0 produces ρ → ∞, T → ∞, and an infinite radiation burst. Mathematically, F ∝ 1/r² diverges, and the theory admits "physics breaks down here." The Zero-Less The...

Zero-Less Mechanics: A Speculative Minimum-Length Regularization for Singularities and Time Dilation

Disclaimer: This is a speculative, non-peer-reviewed preprint. It is not established physics. It does not claim backward time travel or a working time machine. AbstractWe explore a speculative framework, Zero-Less Mechanics, in which zero is replaced by a minimum length L. The fo...

Modeling Sustainable Natural Resource Consumption and Its Impact on Economic Growth: An Empirical Study of Africa and Asia

ABSTRACT The utilization of natural resources plays a crucial role in economic development and enhancing social welfare. This study aims to empirically explore the effect of natural resource rents on economic growth to test whether natural resources are a curse or a blessing for...

A descriptor-driven framework for SiNx:H in crystalline silicon solar cells: linking bonding configuration to device performance and reliability

Hydrogenated silicon nitride (SiN x :H) is a cornerstone material in crystalline silicon photovoltaics, simultaneously providing antireflection functionality and defect passivation. However, these roles are typically treated independently, limiting predictive optimization, partic...

Winter Dietary Composition of Black Francolin (Francolinus francolinus) in Totali Public Game Reserve, Pakistan

The winter diet of Black Francolin (Francolinus francolinus) is poorly documented in Totali Public Game Reserve, Pakistan. We examined crop contents from 24 legally harvested birds (14 males and 10 females) collected during 2022–2024. Thirty-three identifiable food taxa were reco...

Robust feature selection with minimum redundancy for binary gene expression classification in machine learning

High-dimensional gene expression data often contain noisy, irrelevant, and redundant features that can reduce classification accuracy, increase computational burden, and weaken model stability. Therefore, effective feature selection is essential for improving predictive performan...

A Physics-Guided Statistical Framework for Bearing Fault Diagnosis Under Unit Variability and Rotational Speed Uncertainty

Reliable bearing fault diagnosis must differentiate between defects and normal-operation-condition variation. The predictor must remain accurate when shaft speed is uncertain. Conventional accuracy-driven models often ignore false-positive rates and fail to accurately locate faul...

Freshwater contamination from industrial effluent discharge: heavy metal mobilisation, water quality degradation and probabilistic health risk assessment

Context Marble-processing facilities generate slurry-containing wastewater that may mobilise toxic metals through equipment wear, mineral dissolution and the use of polishing materials. Evidence on the combined pollution burden and probabilistic health risks associated with marbl...

Metagenomic analysis of developmental-category-associated fungal communities in the gut contents of Achatina fulica, an intermediate host of Angiostrongylus cantonensis

The invasive giant African snail ( Achatina fulica ) poses serious agricultural and ecological threats and serves as an important intermediate host of the zoonotic parasite Angiostrongylus cantonensis , which causes human eosinophilic meningitis. While its gut bacterial microbiom...

Mathematical modeling of chikungunya transmission dynamics and control using disease-driven machine learning

Abstract The Chikungunya virus (CHIKV) is a significant vector-borne threat; however, few models successfully integrate rigorous theoretical guarantees with efficient, reliable predictive tools. This study aims to address this gap by introducing a nonlinear seven-compartment huma...

Intelligent wireless network selection using linguistic fuzzy neural networks

Wireless networks are fundamental to modern digital communication, and selecting the most appropriate network among competing technologies is a complex multi-criteria group decision-making problem. The evaluation process involves several conflicting attributes, such as bandwidth,...

Protective effect of lycopene against sodium nitroprusside-induced oxidative stress in Artemia salina

Lycopene is a carotenoid with potent antioxidant properties, that is widely used in the food, pharmaceutical, and cosmetic industries, thereby increasing the likelihood of its release into aquatic environments through industrial effluents. Artemia salina is a well-established eco...

A Feature‐Enhanced Artificial Neural Network‐Assisted Adaptive Truncated EWMA Control Chart for Robust Monitoring of Contaminated Processes

ABSTRACT The use of conventional memory‐type control charts can be significantly hindered by the presence of outliers and contaminated observations, as these can lead to excessive false alarms and be difficult to detect true process shifts. To tackle the aforementioned problems,...

Exploring memory effects and chaotic transitions in the fractional–order Bogoyavlenskii dynamical system

We explore the fractional form of the Bogoyavlenskii equation in this work using the modified version of the Riemann-Liouville fractional derivative operator introduced by Jumarie to reveal the memory and hereditary properties of the fractional dynamical systems. This analytical...

A new species of Squamulea (Teloschistaceae) from the Himalayan Region

Squamulea pakistanica sp. nov. is a newly discovered lichen species from the Himalayan moist temperate forests of Pakistan. The genus Squamulea (Teloschistaceae) includes squamulose or subfoliose taxa, many of which are understudied in South Asia. This study aims to characterize...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of bioch...
