    Muayed Khaleel Ibrahim1, Shaymaa Hashim Aneed2, Nidhal Saleh Mohammed2, Kareem Ali Jasim2, Mudatheer M. Al-Slivani3,*

    Chalcogenide Letters, Vol.23, No.7, 2026, DOI:10.32604/cl.2026.082607 - 07 August 2026

    Abstract This study investigates the structural evolution and DC electrical properties of Pb50−xGexTe50 ternary chalcogenide alloys with varying germanium concentrations (x = 5, 10, 15, 20). Synthesized via the melt-quenching technique, the alloys were characterized using Scanning Electron Microscopy (SEM) and temperature-dependent electrical resistivity measurements within the range of 290–475 K. Microstructural analysis revealed that increasing Ge substitution significantly promotes matrix densification, reducing porosity and improving inter-granular connectivity. The DC conductivity exhibits a systematic increase with Ge content up to x = 15, attributed to the increased density of defect states. For instance, as Ge content increases… More >

    Alberto Sandoval-Rangel1, Adalberto Benavides-Mendoza1, Rebeca Betancourt-Galindo2, Eneida Adilene Pérez-Velasco2,*, Bertha Alicia Puente-Urbina2

    Phyton-International Journal of Experimental Botany, Vol.95, No.7, 2026, DOI:10.32604/phyton.2026.083195 - 30 July 2026

    Abstract In soils and substrates, the bioavailability of Zn2+ is generally low. The use of zinc oxide nanoparticles (ZnO-NPs) has emerged as a promising strategy in agriculture to improve zinc availability and stimulate plant growth. Their physicochemical properties and biocompatibility promote greater micronutrient uptake and the regulation of physiological processes in plants. In this study, the effects of five concentrations of ZnO-NPs (0, 100, 250, 500, and 1000 mg L−1) and two application methods (foliar or drench) on the growth, gas exchange, and flowering quality of marigold were evaluated. ZnO-NPs significantly influenced plant growth; plant height and… More >

    Nuclear Test Sites as Natural Experiments: Conceptual Perspectives on Plant Evolution from the New Mexico Desert

    Gian Marco Ludovici1,2,*, Paola Amelia Tassi2, Alba Iannotti2,3, Colomba Russo2,3, Francesco Gargallo di Castel Lentini4, Timothy Alexander Mousseau5, Andrea Malizia1,2

    Phyton-International Journal of Experimental Botany, Vol.95, No.7, 2026, DOI:10.32604/phyton.2026.083056 - 30 July 2026

    Abstract The detonation of nuclear weapons, beginning with the Trinity test in New Mexico and followed by the bombings of Hiroshima and Nagasaki, created distinct environments of ionizing radiation exposure. While the ecological consequences of reactor accidents at Chernobyl and Fukushima have been extensively investigated, the potential evolutionary implications of historical weapons testing for plant communities remain comparatively underexplored, particularly in arid ecosystems. This review synthesizes available, yet fragmented, evidence to examine the hypothesis that residual radionuclides in arid test-site environments may have acted as potential selective pressures influencing plant persistence and stress-associated traits in native… More >

    Metabolic Responses of Wheat Spike Tissue Associated with Fusarium Infection in Genotypes Differing in Type II Resistance

    Jurica Duvnjak1, Daniel Kujundzic2, Katarina Sunic Budimir1, John C. D’Auria2, Valentina Spanic1,*

    Phyton-International Journal of Experimental Botany, Vol.95, No.7, 2026, DOI:10.32604/phyton.2026.082576 - 30 July 2026

    Abstract In this study, metabolomic profiling using gas chromatography–mass spectrometry (GC-MS) revealed clear distinctions between Fusarium-infected and control wheat spikes, as shown by the separate clustering of infected samples. Out of 222 detected features, eight were found to be significantly altered in infected spikes compared to controls, highlighting specific metabolic changes associated with the plant’s response to Fusarium head blight (FHB) stress. In response to Fusarium infection, wheat exhibited significant metabolic reprogramming, with both reductions and accumulations of key metabolites. A decrease in 3-methoxytyramine (28.9–85.3%), octylamine, malic acid, and homonojirimycin suggests their early involvement in defence-related pathways… More >

    The Intervention Effects of Self-Perspective Imaginative Empathy on Mental Illness Stigma in Chinese Undergraduates

    Siliang Yang1,2,*, Gan Jin3

    International Journal of Mental Health Promotion, Vol.28, No.7, 2026, DOI:10.32604/ijmhp.2026.078761 - 30 July 2026

    Abstract Background: Reducing mental illness stigma is critical for mental health literacy enhancement in China, where stigmatization remains pronounced among undergraduates. Imaginative empathy is a promising anti-stigma intervention, but its specific effects and the potential moderating role of gender remain under-explored. Methods: Three studies were conducted with 18–22-year-old Chinese undergraduates. Study 1 (n = 223, survey design) explored gender’s moderation on empathy-stigma links. Study 2 (n = 217, 2 × 2 × 3 mixed design) tested the intervention effect of self-perspective imaginative empathy. Study 3 (n = 71, 2 × 2 × 2 mixed design) verified gender… More >

    Improving ENUM-Sieve Reduction Algorithm for Prime Cyclotomic Lattices

    Kazutaka Toda1, Yuntao Wang1,*, Hyungrok Jo2, Yang Li1

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.083407 - 27 July 2026

    Abstract The rapid evolution of quantum computing poses a fundamental challenge to classical public-key cryptosystems, accelerating the adoption of lattice-based post-quantum cryptography in large-scale digital infrastructures, including Future Mobile Internet Technologies (FMIT) and their convergence applications (FMIT-CA). As lattice-based cryptography is expected to play an important role in such environments, accurate hardness estimation and parameter assessment of underlying lattice problems have become increasingly important. Since the security of these cryptographic schemes is closely related to the computational hardness of the Shortest Vector Problem (SVP), improving practical SVP-solving techniques contributes indirectly to the security evaluation of such… More >

    Instantaneous Mobility Indicators for Risk Management in Wind Farms: A Computer Modeling Approach

    Guglielmo D’Amico1,*, Edoardo Lui2, Filippo Petroni1

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.082608 - 27 July 2026

    Abstract This paper develops an operational framework for short-horizon risk management in multistate stochastic systems, with application to wind farm performance. We focus on instantaneous mobility-based indicators derived from finite-state continuous-time Markov chains, which capture the local propensity of a system to transition between states. Unlike classical reliability and availability measures, these indicators provide a dynamic description of system behavior. The indicators are interpreted as policy signals to support decision-making under budget constraints. We introduce a state-conditional expected short-horizon loss, representing non-production risk, and use it to evaluate ranking-based intervention strategies. The framework is applied to More >

    Dominick Shoha#, David Lei#, Tyler Truong, Sophia Strukel, Elliot Enshaie, Vikrant Rai*

    BIOCELL, Vol.50, No.8, 2026, DOI:10.32604/biocell.2026.078846 - 27 July 2026

    Abstract Diabetes, inflammation, and neurodegeneration, particularly Alzheimer’s disease (AD), are deeply interconnected (brain diabetes). Type 2 diabetes mellitus (T2DM) acts as a significant risk factor for neurodegenerative diseases like Alzheimer’s (AD) and Parkinson’s (PD) by inducing chronic inflammation, oxidative stress, and metabolic dysfunction. Hyperglycemia drives neuroinflammation and damages the blood-brain barrier (BBB), exacerbating cognitive decline and neuronal loss. Chronic inflammation acts as a central bridge, linking high blood sugar, insulin resistance, and metabolic dysfunction in the brain to the buildup of amyloid plaques, tau tangles, and neuronal damage due to shared insulin signaling issues in the More >
