Optimizing decentralized wastewater allocation to urban green spaces in the water scarce megacity of Tehran

Abstract Water scarcity is among the most pressing global challenges, and conventional systems increasingly fail to secure reliable urban water supplies. Reusing municipal wastewater for irrigation offers a sustainable, low-cost option for sustaining urban green spaces, the large...

Enhancing Sand–Geotextile Interface Strength: Effects of Polyurethane, Polyvinyl Alcohol, and Cement Slurry

Abstract Geotextiles are widely used in geotechnical engineering to reinforce soil and enhance the stability of various structures. This study investigates the effectiveness of different treatments in improving the sand–geotextile interface. A series of direct shear tests were co...

Black phosphorus quantum dots for resistome mitigation: Mechanistic insights and rational engineering

The emergence of antibiotic resistance as a global environmental challenge has intensified the need for advanced strategies capable of addressing antibiotic contamination while reducing the environmental drivers of resistance dissemination. Although black phosphorus quantum dot (...

The free vibration and supersonic flutter analyses of a three-directional functionally graded conical panel in a thermal environment

In the present study, free vibration and aeroelastic stability (flutter) analyses are investigated for a three-directional functionally graded material (FGM) conical panel subjected to a yawed supersonic fluid flow in a thermal environment. It is assumed that the material is fabr...

Unlocking the impact of ICALL across proficiency levels: EFL learners’ language achievement and multidimensional engagement

This quantitative quasi-experimental study examined whether Intelligent Computer-Assisted Language Learning (ICALL)-based instruction improved Chinese English as a Foreign Language (EFL) learners’ language achievement and multidimensional engagement across elementary, intermediat...

Intermittent fasting in diabetic retinopathy: microbiome modulation, mechanisms, and clinical insights.

Intermittent fasting, a nonpharmacological approach, shows promise for controlling diabetic retinopathy but lacks concrete human evidence directly associating intermittent fasting with eye responses. This review highlights preclinical research insights about intermittent fasting...

Functionalization of Mesoporous Carbon by Bovine Serum Albumin for Application in an Electrochemically Controlled Delivery System of Imatinib Anticancer Drug

Background: Imatinib (IM) is a tyrosine kinase inhibitor that targets the growth factor receptors. IM has demonstrated remarkable clinical efficacy across multiple cancer types. IM abrogates the activity of the Bcr-Abl oncoprotein, leading to the inhibition of cell proliferation...

Safe and adaptive control of non-stationary stochastic systems via Lyapunov-constrained distributional reinforcement learning

Abstract Non-stationary environments pose significant challenges for reinforcement learning (RL), particularly in safety-critical applications like robotics and energy systems, where adaptability, stability, and robustness to uncertainty are essential. This paper introduces Lyapu...

Analytical determination of contamination depth of 137 Cs point sources in reactor building walls

Abstract The presence of radioactive contamination in concrete structures poses a silent yet serious threat to both environmental safety and public health. Such contamination, if not properly localized, can lead to prolonged radiation exposure, difficulties in decommissioning, an...

Interactions of Multiple Curved Cracks in an FGP Strip: Mixed Mode Analysis

ABSTRACT This paper investigates multiple embedded curved cracks in a functionally graded piezoelectric (FGP) strip. In order to compute Mode I/II stress intensity factors (SIFs) and electric displacement intensity factor (EDIF), distributed dislocation technique (DDT) is employe...

Vibration-based non-destructive evaluation of dual cracks in bidirectionally functionally graded nanobeams: a nonlocal elasticity–metaheuristic optimisation framework for structural health monitoring

Cracks in functionally graded nanobeams used in MEMS/NEMS devices can significantly reduce stiffness and reliability, and identifying multiple cracks at the nanoscale is challenging because nonlocal effects and bidirectional material gradation must be accounted for. To address th...

A soft-switched, trans-inverse step-up DC-DC converter with minimal components based on built-in transformer

A new single-switch, high-gain DC-DC converter with low component count and low input current ripple is proposed for renewable energy systems. The proposed topology integrates a Three-Winding Built-In Transformer (TWBIT) with zero DC magnetizing current and a voltage multiplier t...

Suggestibility, Psychic Pain, and Body Dysmorphic Disorder Symptoms: The Mediating Role of Defense Mechanisms

Body dysmorphic disorder (BDD) is characterized by an increased self-perception of one’s own appearance and an intense aspiration for beauty, which may elevate the likelihood of being easily suggestible, cause mental suffering, and impair ego functions. This study investigated th...
