This paper reports the first production of the medical radionuclide 103Pd via the 99Tc(7Li,3n)103Pd reaction and presents the first measured cross-sections for this process between 20 and 34 MeV, identifying a maximum yield at 30 MeV.
This paper introduces a dynamic zero-pole engineering paradigm in a VO2-based non-Hermitian metasurface that unifies bound states in the continuum and coherent perfect absorption, enabling reconfigurable transitions between high-Q states and near-perfect single-port absorption with 99.8% efficiency at terahertz frequencies.
This paper demonstrates that a spectrally resolved Rayleigh and Mie scattering system, utilizing a Fabry-Perot interferometer and a scattering model to mitigate dust, condensation, and flare light interference, successfully measures velocity and temperature in a transonic wind tunnel with high accuracy, even in the presence of shock waves and naturally occurring aerosols.
This study demonstrates that mechanically scratching an n-Si wafer using a CNC machine to create a micro-grooved SnO2/n-Si heterojunction significantly enhances photodetector efficiency by boosting photocurrent, responsivity, and response speed through improved light trapping and reduced trap-assisted recombination, despite a trade-off in specific detectivity caused by increased dark current.
This paper numerically investigates how non-local interactions between supersonic spin-polarized currents in a one-dimensional ferromagnetic channel, modeled by a magnetic square well scheme, generate dissipative exchange flows that evolve into frequency combs through the interplay of spin superfluidity and contact solitons.
This paper introduces a lightweight, interpretable diagnostic called the "anchor-burst indicator" that detects early instability in the three-body problem by monitoring persistent bursts in an effective configuration anchor, offering performance comparable to standard methods without requiring training or complex computations.
This study utilizes high-speed particle tracking velocimetry in soft PDMS microtubes to demonstrate that compliance-induced flow transition is characterized by a distinct near-wall localization of velocity fluctuations and lacks a universal scaling law, revealing significant inter-study heterogeneity that challenges the reliability of extrapolating stability thresholds from single assumed power laws.
This study utilizes the Galerkin finite element method to demonstrate that while a strong magnetic field significantly suppresses heat transfer in a CuO-water nanofluid-filled vented cavity with a rotating core cylinder, optimizing the Reynolds number and cylinder rotation direction can substantially enhance thermal efficiency, offering valuable design insights for advanced thermal management systems.
This paper introduces a theorem-based complex-quaternionic Riemann–Silberstein formalism that unifies the electric and magnetic components of single-photon wave packets into a single helicity-resolved biquaternionic field, thereby simplifying Maxwell's equations and clarifying the distinct operational roles of spectral localization, helicity selection, and mode matching within standard quantum electrodynamics.
This paper reports the experimental realization of a tripartite quantum phase, where extended, localized, and critical states coexist in a quasi-periodically driven orbital optical lattice, using a novel two-stage protocol to prepare, detect, and characterize their distinct transport properties with ultracold atoms.
