Self-regenerating photocatalytic water treatment systems: integrating cognitive AI control, bio-inspired self-healing, and thermoelectric energy harvesting

Conventional photocatalytic water treatment systems face persistent limitations in terms of catalyst deactivation, energy consumption, and adaptability to variable influent quality. This review examines the integration of three emerging technological domains, machine learning dri...

Unilateral Sacroiliac Hemiagenesis in a Young Woman Presenting With Chronic Mechanical Low Back and Buttock Pain: A Case Report

Sacral agenesis is a rare congenital malformation belonging to the spectrum of caudal regression syndrome, whose clinical manifestations are highly variable and depend on the phenotype of the disease.We report the case of a young woman who presented with chronic mechanical low ba...

Hybrid gravity energy storage and fast hydraulic accumulator for reliability-constrained industrial renewable systems: Multi-timescale design and dispatch framework

High-power industrial electrification requires hybrid renewable energy systems (HRES) that simultaneously minimize cost, satisfy stringent adequacy targets, and withstand fast power ramps that conventional long-duration energy storage cannot efficiently absorb. This paper propose...

On flat pseudo-Euclidean solvable Malcev algebras

A pseudo-Euclidean Malcev algebra is a Malcev algebra equipped with a non-degenerate symmetric bilinear form. In this paper, we introduce a curvature operator for pseudo-Euclidean Malcev algebras, generalizing the notion of curvature for pseudo-Euclidean Lie algebras. We define f...

Impact of Wind-Induced Phase-Shift Errors on RIS-Assisted Cell-Free Massive MIMO Networks: Spectral and Energy-Efficiency Analysis

Reconfigurable intelligent surfaces (RISs) can improve spectral efficiency (SE) and energy efficiency (EE) in cell-free massive multiple-input multiple-output (CF-mMIMO) networks by coherently controlling reflected propagation paths. Outdoor panels, however, can experience wind-d...

Evaporation of primordial black holes with multimodal mass and extended spin distributions: cosmological imprints on the effective number of relativistic species

Abstract Primordial black holes (PBHs) form through several distinct mechanisms, each imprinting a characteristic mass function that a single-mass treatment risks erasing. Building on the code, we introduce ( https://doi.org/10.5281/zenodo.22699162 ), implementing four mass funct...

Ceramic tiles production using phosphate marl by-products and phosphogypsum

The large-scale accumulation of phosphogypsum (PG) and phosphate marl (YM) remains a major environmental challenge in phosphate-producing regions, while their potential as alternative ceramic raw materials is still insufficiently explored. This study investigates the combined uti...

Thermal expansion kinetics of cementitious materials under different heating regimes: Implications for thermal energy storage durability

The heating rate is an important parameter controlling the thermos mechanical degradation of cementitious materials during high temperature cyclic exposure. This is relevant to thermal energy storage and fire scenarios. This paper studies the influence of heating rate on thermal...

On Titchmarsh’s Theorem for the Canonical Bessel Transform: Weighted Sobolev Spaces versus Classical Lipschitz Classes

Abstract This paper establishes Titchmarsh-type theorems for the Canonical Bessel Transform (CBT) in weighted Sobolev spaces associated with Lipschitz and Dini–Lipschitz type conditions. We characterize the decay and integrability properties of the CBT in the spaces $$\mathcal {L...

A comprehensive analysis of lung cancer status changes over 10 years: results of Moroccan cohort

Assessing long-term trends in lung cancer (LC) patients is challenging, particularly in regions with limited data. We present findings from a real-life Moroccan cohort. This is a retrospective study that included patients diagnosed with LC as a primary malignancy between January...

Essential oils and plant extracts for sustainable crop protection

In recent years, environmental issues related to the extensive use of synthetic pesticides have attracted great attention to finding sustainable methods of plant protection. Plant-derived materials, particularly essential oils (EOs) and plant extracts, are considered to be potent...

Pogostone as a bioactive natural compound with potential relevance for functional foods, nutraceuticals, and food preservation: a review

Pogostone, a characteristic secondary metabolite of Pogostemon cablin , has recently gained attention due to its diverse biological activities and potential relevance as a bioactive compound for functional food development. This review summarizes current knowledge on the origin,...

Does ESG performance enhance financial performance? Evidence from Morocco and the moderating role of corporate governance

Purpose This study addresses the ongoing debate on the environmental, social and governance (ESG)–financial performance nexus by examining whether ESG performance enhances firm profitability and whether corporate governance mechanisms condition this relationship in an emerging ma...

Comprehensive geriatric assessment in oncology in Morocco: status report using an interpretive approach and recommendations

In the context of Morocco’s progressively aging population, Comprehensive Geriatric Assessment (CGA) plays a major role in the early detection of frailty among older patients with cancer and in adapting care to their specific needs. The objectives of this study were to assess the...
