Bubbles tower solutions to a fourth-order elliptic equation with subcritical nonlinearity

This paper is concerned with the nonlinear elliptic problem involving nearly critical exponent (Pε): Δ2u=K|u|(8/(n−4))−εu in Ω, Δu=u=0 on ∂Ω, where Ω is a bounded smooth domain in Rn, n≥ 5, ε is a small positive parameter and K is a C3 positive function on Ω¯. As ε goes to zero,...

Biochemical responses of barley seeds to the cumulative effects of treated wastewater irrigation

Treated wastewater (TWW) may still contain residual pollutants and chemicals that can accumulate in plant tissues and seeds, potentially disrupting plant metabolism and physiological processes. In this study, we investigated the cumulative effect of TWW on the primary metabolites...

Interfacial Structuring and Functional Enhancement in Pectin-Sodium Caseinate Films Loaded with Deverra tortuosa Essential Oil Nanoemulsions

This study aimed to develop bioactive pectin-based films incorporating Deverra tortuosa (D. tortuosa) essential oil (EO) nanoemulsions stabilized by sodium caseinate for potential active food packaging applications. EO nanoemulsions were incorporated into a pectin–maltodextrin ma...

Packed‐bed thermal storage solar air collectors with porous media: Performance influencing parameters and enhancement strategies

Abstract Solar air heaters (SAHs) are promising low‐cost solar thermal systems for heating and drying applications; however, their performance is limited by the low convective heat transfer coefficient between the absorber and the flowing air. Double‐pass configurations incorpora...

Current-vector trajectory–based diagnosis of open-circuit faults in NPC inverters for SSSC applications

Abstract This paper presents an enhanced fault diagnosis method for identifying open-circuit faults in the switches of Three-Level Neutral Point Clamped (NPC) inverters integrated into Static Synchronous Series Compensator (SSSC) systems. Although previous studies have mainly foc...

Contrasting Responses of Two Sympatric Canids, the African Golden Wolf and Red Fox, to Anthropogenic and Habitat Related Factors in Arid Landscapes of Southern Tunisia

ABSTRACT Human‐induced landscape changes increasingly shape the spatial ecology of wildlife, particularly in arid ecosystems where resources are limited. This study investigates how the combined effects of anthropogenic pressures and prey availability influence the distribution a...

ANTIBODY: An Immune-System Architecture for Long-Horizon AI Agent Oversight (Doctoral Research Proposal)

Long-horizon autonomous agents degrade in ways current oversight cannot catch, and the tools used to catch them are themselves degrading. This proposal investigates an external, model-agnostic oversight layer built on five principles drawn from immunology and reliability engineer...

Calibration Is Not Enough: An Anytime Monitor for Trustworthy Abstention

Version 2 (9 September 2026) — erratum. An independent audit found several statements in v1 that the paper's own logs and results did not support — stale prose from an earlier run of the same experiment, not a change to the method. Corrected: the batch baseline's overall answered...

Performance enhancement of domestic gas stoves through inclined burner cap ports

This work investigates numerically the effects of the inclination angle of the burner cap on the thermal performance and efficiency of liquefied petroleum gas stove. The simulations carried out using ANSYS Fluent were validated using the experimental data to ensure reliability. I...

Digitalizing Sustainability Assessment in Agriculture: The SUSTIN-OLIVA Indicator-Based Application for Tunisian Olive Farming Systems Under Agroecological Transition

With the shift in Tunisian olive growing toward more intensive models, significant sustainability concerns have emerged. Aware of the need for reliable and operational tools to support agricultural policies under climate and socioeconomic pressures, we address a digitalized metho...

Integrated experimental and modeling study of air psychrometry and velocity effects on cooling pad performance

This study presents a combined experimental and modeling investigation of cellulose-based evaporative cooling pads, focusing on the synergistic effects of inlet air psychrometric conditions and air velocity on cooling performance. Unlike conventional studies that examine temperat...

Influence of layer thickness on the tensile and low-velocity impact behavior of FDM-printed PLA–CF composites: A combined numerical and experimental study

Predicting the mechanical behavior of fused deposition modeling (FDM) carbon fiber-reinforced thermoplastics remains challenging due to their process-induced heterogeneity and anisotropy. This study investigates the influence of layer thickness on the tensile and low-velocity imp...

Sol–gel synthesis of ZnO @ SiC heterojunctions from photovoltaic waste for enhanced paracetamol photodegradation

Abstract Exponential growth in photovoltaic energy production has created a critical environmental challenge: managing silicon carbide (SiC) waste from wafer cutting processes. This study addresses this challenge by transforming photovoltaic waste into high‐value photocatalytic m...

Effect of Different Metal Doping of ZnO Nanoparticles on Photocatalytic Degradation of Dye Wastewater

Undoped ZnO and metal-doped ZnO (ZnO:M) nanoparticles (NPs), with M [Formula: see text] Ca, V and Al, have been synthesized, with the same metal content ([Formula: see text]%), by the sol–gel method. The M-doping effects on the ZnO NPs properties are studied by a variety of techn...

Nano-enhanced PCM-assisted solar stills: A systematic review of performance, economics, and sustainability

Abstract Freshwater scarcity is an escalating global challenge, particularly in arid, remote, and off-grid regions where conventional desalination technologies remain energy-intensive and costly. Solar stills provide a simple and sustainable desalination option; however, their br...
