The Feasibility Test of Electric Propulsion Systems: Case Study for a Light and Fixed‐Wing Aircraft

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This study investigates the feasibility and performance of a fully electric propulsion system (EPS) integrated into a light fixed‐wing aircraft. The system consists of a 65 kW‐class electric motor, a high‐efficiency inverter, and dual lithium‐ion battery packs with a total capacity of 27 kWh—collectively engineered to fulfill both power ...

Effect of Microchannel Geometry on Nanoparticle Deposition in Nanofluid Flow

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study numerically analyzed nanoparticle deposition in microchannels with varying geometries. Deposition per unit area decreases significantly with increasing bend angle (28.612 to 8.941 between 30° and 120°) and bend radius (11.922 to 4.769 between 0.2 and 0.4 mm). Acute bends and small radii enhance centrifugal forces and flow separation, leading

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Ginsenoside Rg1 Ameliorates LPS‐Induced Sepsis‐Associated Lung Injury in Mice via VEGFC/D‐VEGFR3 Signaling‐Mediated Lymphangiogenesis and Lymphatic Remodeling

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Sepsis‐induced acute lung injury (ALI) remains challenging to treat, with conventional anti‐inflammatory therapies offering limited efficacy. The lymphatic system is crucial for removing edema and inflammatory mediators, and its impairment can exacerbate lung injury.
