Abstract Powdery mildew of cucumber (Cucumis sativus L.) is a destructive disease caused by Podosphaera xanthii (Castagne) U.Braun & Shishkoff. This study aimed to investigate the antifungal effect of extracts of Ulva lactuca, Spirulina platensis, and Nostoc muscorum against P. xanthii and to improve the physiological and morphological traits of cucumber under commercial greenhouse conditions. The chemical composition of the individual extracts from U. lactuca, S. platensis, and N. muscorum was analyzed utilizing High-performance Liquid Chromatography (HPLC) and Gas Chromatography/Mass spectrometry (GC/MS). Cucumber plants were sprayed twice with 5% of the crude extracts of U. lactuca, S. platensis, and N. muscorum and their mixture (U. lactuca, S. platensis, and N. muscorum).… More >

Abstract Samaras represent a unique category of fruits characterized by a seed accompanied by lightweight wing-like appendages that facilitate dispersal. Variations in structure play a crucial role in influencing the flight patterns of these seeds, shaping their reproductive strategies. To explore the mechanisms behind different samara flight behaviors, we developed an effective approach that adjusts mass distribution on a plate to replicate a range of three-dimensional flight patterns. Through this methodology, we experimentally identified and classified four distinct flight modes. Furthermore, numerical analysis of the three-dimensional vortical structures provided deeper insights into the aerodynamics underlying samara-inspired More >

Abstract Although the arched structures inspired by biomaterials have been extensively applied in construction for load bearing, they remain a relatively new component for absorbing energy in impact scenarios. The hierarchical re-entrant honeycomb (RH) with horizontal and vertical arched units (namely, horizontally and vertically arched hierarchical RH (AHRH) – HAHRH and VAHRH) are constructed, and their metallic specimens are fabricated for compression testing. Compared to well-known circular units, the horizontal and vertical arched units exhibit an increase in plateau stress (PS) by 16.8% and 23.8%, and an enhancement in specific energy absorption (SEA) by 10.8% and… More >

Abstract Conventional energy-absorbing mechanical metamaterials primarily dissipate energy through irreversible plastic deformation, buckling, or fragmentation. Their applications are limited by structural fractures caused by 45° shear stresses and their suitability only for single-use impact protection, lacking the capability for repeated energy absorption. Inspired by the cancellous bone of the human skull, a Tangent Arc Curve Structure (TACS) was proposed in this study, followed by the modeling and fabrication of four types of 3D-TACSs: tensile, tensile-rotational, orthogonal, and diagonal. The shear resistance and repeatable energy absorption capabilities of TACS were systematically investigated through theoretical analysis, compression experiments,… More >

Abstract Background: While quantitative research has determined that emotional distress and psychiatric illness among frontline healthcare workers increased with the COVID-19 pandemic, detailed qualitative data describing their personal experiences are needed in order to make appropriate plans to address provider mental health in future pandemics. This study aims to further explore the psychological effects of the pandemic on COVID-19 ICU clinicians and administrators through focus groups. Methods: Two separate 2-h focus groups of physicians were conducted, one with frontline faculty clinicians and another with administrators. Qualitative data analysis was conducted. Results: In September and November 2023, volunteer… More >

Abstract Electrospinning has gained significant importance across various fields, including biomedicine, filtration, and packaging due to the control it provides over the properties of the resulting materials, such as fiber diameter and membrane thickness. Chitosan is a biopolymer that can be utilized with both natural and synthetic copolymers, owing to its therapeutic potential, biocompatibility, and biodegradability. However, producing electrospun chitosan is challenging due to its high solution viscosity, which often results in the formation of beads instead of uniform fibers. To address this issue, the spinnability of chitosan is significantly enhanced, and the production of continuous More >

Abstract Spinal cord injury presents a significant challenge in regenerative medicine due to the complex and delicate nature of neural tissue repair. This study aims to design a conductive hydrogel embedded with magnetic MgFe₂O₄ nanoparticles to establish a bioelectrically active and spatially stable microenvironment that promotes spinal cord regeneration through computational analysis (BIOVIA Materials Studio). Hydrogels, known for their biocompatibility and extracellular matrix-mimicking properties, support essential cellular behaviors such as adhesion, proliferation, and migration. The integration of MgFe₂O₄ nanoparticles imparts both electrical conductivity and magnetic responsiveness, enabling controlled transmission of electrical signals that are crucial for guiding… More >

Abstract To advance the performance of solid oxide fuel cells (SOFCs), this work proposes a novel biomimetic flow field architecture inspired by the geometric arrangement of sunflower florets. Drawing on natural principles of optimal spatial distribution, a multi-physics simulation model of the resulting Sunflower Bionic Flow Field (SBFF) was developed. Building upon this foundation, an enhanced configuration was introduced by integrating an annular channel, yielding a modified variant referred to as Modified Sunflower Bionic Flow Field (MSBFF). For comparative purposes, a conventional Traditional Parallel Flow Field (TPFF) was also analyzed under identical conditions. Simulation results underscore… More >

Abstract Background: Patients with hemato-oncological malignancies may respond insufficiently to vaccination, especially in terms of antibody titer. The antibody response depends on the type of malignancy as well as the type and timing of treatment. We intended to evaluate this using real-world data from patients of our regional hospital. This study also considers the role of immune status, including T-cell activation markers, in predicting vaccination success. Methods: Seventeen patients of our hospital having a hematological malignancy were included in this study, including myeloma, lymphoma, as well as acute myeloid leukemia (AML) and chronic lymphoid leukemia (CLL).… More >

Abstract This research presents a novel nature-inspired metaheuristic optimization algorithm, called the Narwhale Optimization Algorithm (NWOA). The algorithm draws inspiration from the foraging and prey-hunting strategies of narwhals, “unicorns of the sea”, particularly the use of their distinctive spiral tusks, which play significant roles in hunting, searching prey, navigation, echolocation, and complex social interaction. Particularly, the NWOA imitates the foraging strategies and techniques of narwhals when hunting for prey but focuses mainly on the cooperative and exploratory behavior shown during group hunting and in the use of their tusks in sensing and locating prey under the… More >
