Compartment-Specific Bacterial Communities and Their Functional Potential in the Desert Plant Citrullus colocynthis

Plants inhabiting arid and semi-arid ecosystems rely on their associated microbiota to withstand drought, heat, salinity, and nutrient limitation. We investigated the bacterial communities associated with the foliar tissues, roots, and rhizospheric soil of the desert plant Citrul...

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...

3D-printed PLA/CNT/pyrrhotite ash composites for absorption-dominated EMI shielding and improved flame retardancy

Combining EMI shielding with flame retardancy in a single lightweight composite remains a key requirement for next-generation electronics and communication hardware. This work reports multifunctional 3D-printed PLA composites built from hybrid CNT/pyrrhotite ash (PA) fillers, fur...

From salt-in-water to water-in-salt: the emergence of glass-like dynamics and the transference number controversy

The transition from dilute salt-in-water (SiW) electrolytes to highly concentrated lithium bis(trifluoro methylsulfonyl)imide (LiTFSI) water-in-salt (WiS) systems represents a fundamental shift in the physics of ion transport. We propose that this transition is best understood us...

Measuring the Azorean blue economy: a value chain approach

Economic activities associated with marine and coastal resources – commonly referred to as the blue economy – play a central role in coastal regions such as Portugal. Despite the Azores' small population and structural constraints, the blue economy holds significant potential for...

Decoupled DC-bus voltage regulation and adaptive energy management for fuel cell/battery/supercapacitor powered vehicle

This paper presents a hierarchical energy management and control framework for a fuel cell–battery–supercapacitor hybrid electric vehicle with regulated DC-bus voltage. The proposed architecture decouples DC-bus voltage regulation from energy management by generating a net load c...

Distorting the trust signal: review subjectivity, polarity and the conditional bias of online merchant ratings

Purpose This study examines how the linguistic subjectivity of online reviews distorts the aggregate merchant rating, the system-level trust signal on which buyers in complex digital markets increasingly rely. It asks whether subjectivity biases the rating, through what mechanism...

From surface to deep sea: A depth-resolved vertical profile of microplastics in the Canary Basin

Microplastic (MP) contamination of the open ocean is well documented, yet the vertical structuring of MPs and the role of water masses in shaping deep-water inventories remain poorly resolved along the eastern boundary of the North Atlantic Subtropical Gyre. Here we present a hig...

Quantitative analysis of P2O5 in solid raw phosphate matrices using laser-induced breakdown spectroscopy (LIBS) for online mining industry monitoring

Laser-Induced Breakdown Spectroscopy (LIBS) is increasingly considered for real-time compositional monitoring in the mining industry, offering minimal sample preparation, multi-element capability, and sub-second analysis times. The growing global demand for fertilizers, combined...

From Digital Twin to AI-Integrated Control: A Review and Research Agenda for Large-Scale PEM Electrolyzer Plant Management

Large-scale green hydrogen production via PEM electrolysis demands control strategies that surpass the limitations of traditional distributed control systems (DCSs). Digital twin (DT) technology has been introduced as a structured design framework for predictive maintenance and o...

Wheat yield prediction using machine learning, proximal sensing, nitrogen and climate data for Oklahoma

Purpose Accurate in-season yield prediction is a practical prerequisite for informed nitrogen (N) management decisions in winter wheat production, yet no rigorous framework has been established and tested against the tools producers currently rely on. Our study developed and eval...

Agricultural Reuse of Phosphogypsum in Contrasting Soils: Wheat Yield, Potentially Toxic Element Uptake, and Soil Microbial Community Responses

Phosphogypsum (PG) is a high-volume industrial by-product that is receiving increasing attention as an alternative soil amendment. This study presents a two-year pot experiment evaluating the effects of PG on spring wheat (Triticum aestivum L.) grown on two contrasting soils: an...

Ritualization of Complex Skill Acquisition

Abstract The processes by which traditional artistic knowledge is transmitted across generations with high fidelity remain poorly understood, particularly in non-Western contexts. This study examines how mastery of Indian miniature painting, a technically demanding and culturally...

Atmospheric Fate of Hydrofluoroethers: Degradation of Parent Compounds and Primary Products by Multiple Oxidants

Abstract Hydrofluoroethers (HFEs) are widely used as substitutes for ozone-depleting substances, yet their atmospheric fate remains poorly understood. We investigated the gas-phase degradation of HFE-7100 (C4F9OCH3) and HFE-7200 (C4F9OC2H5) by OH, Cl, and NO3 at 298 K. The measur...

Panicum virgatum L. salt tolerance improved by inoculation with multi-stress tolerant Bacillus

Soil salinity is a key limiting factor for agricultural production, even for moderately salt-tolerant crops such as switchgrass ( Panicum virgatum L.). We hypothesized that switchgrass resistance to salt stress will increase when seeds are inoculated with bacteria that support pl...

Coordinated resistance–virulence organization across urban microbiomes reveals context-dependent ecological structuring

Microbial communities in built environments are shaped by functional traits associated with persistence, ecological interaction, and pathogenic potential. While antimicrobial resistance (AMR) genes and virulence factors (VFs) are typically studied independently, their coordinated...

Board gender diversity and accounting quality: on the moderating role of national culture and legal origins

Purpose Motivated by the growing literature on the role of board gender diversity in shaping firms' outcomes, and by the recent challenges and discussions around accounting quality, this paper proposes to study the extent to which board gender diversity influences accounting qual...

Hydrogeophysical Characterization to Inform Future Mine Dewatering Strategies: Case Study of the Beni Amir Phosphate Deposit, Morocco

Groundwater management presents a challenge for open-cast phosphate mining within the Beni Amir deposit, Oulad Abdoun Basin, Morocco, where future mining operations are progressively reaching deeper saturated phosphate layers. This study integrates six Electrical Resistivity Tomo...
