This paper demonstrates that generalized Bacon-Shor codes and quantum low-density parity-check constructions can surpass the fundamental hashing limit and, under certain conditions, the asymptotic quantum Singleton bound for quantum Pauli channels, particularly in low-rate schemes and biased noise environments.
The Simβ-AD study established a methodology for assessing radioactive waste activation at the CEMHTI Cyclotron by validating neutron fluence measurements from activation foils against four Monte-Carlo codes (FLUKA, MCNP6, PHITS, and RayXpert®), demonstrating good agreement between experimental data and simulations using simplified models.
The ENEA Integrated Laboratory of Radioactivity Measurement and Monitoring leverages its extensive equipment and specialized expertise to perform comprehensive environmental and internal dosimetry analyses of diverse radionuclides across its centers in Saluggia, Casaccia, and Trisaia, ensuring accuracy through continuous intercalibration.
This study demonstrates that Indonesia's RSG-GAS research reactor, utilizing a modified low-enriched uranium electroplating capsule, can simultaneously produce Molybdenum-99 and enhance Actinium-225 yields to 4.3 GBq through optimized irradiation and multiple milking cycles.
This study demonstrates that a robust machine learning framework, featuring a five-step detector-agnostic preprocessing pipeline and dimensionality reduction, achieves perfect classification accuracy for both single-isotope and complex irradiated material gamma-ray spectra across NaI(Tl), CZT, and HPGe detectors, with only minor performance drops observed in specific high-resolution scenarios.
This study presents an exact analytical formulation for transverse surface waves in a functionally graded piezoelectric half-space with a triple dielectric overlayer, revealing how material ordering, substrate grading, and thickness allocation serve as independent design parameters to precisely tailor wave dispersion and electromechanical coupling characteristics.
This study proposes and optimizes a highly sensitive surface plasmon resonance biosensor utilizing a hybrid structure of boron nitride, barium titanate, black phosphorus, and copper on a BK7 prism to achieve exceptional detection performance for tuberculosis biomarkers in blood plasma.
This paper introduces a dual-detector setup that enables composition-independent neutron scatter correction, transforming neutron tomography from a qualitative visualization tool into a quantitative analysis method for heterogeneous, dynamic systems containing strong scatterers by reducing systematic errors in concentration measurements from 17% to 2% without requiring sample-dependent calibration.
This study employs the quasi-lattice theory, combined with Butler and Moelwyn-Hughes models, to predict the thermodynamic, structural, surface, and transport properties of molten Sn-Tl alloys, revealing that their stability and segregation decrease with rising temperature while suggesting a potential transition from segregation to ordering at approximately 1914.15 K.
This study utilizes dynamic multiphase simulations to demonstrate that interfacial contact topology, particularly the ratio of slag–coke to iron–coke contact areas, significantly governs molten iron–slag dripping behavior and phase separation in hydrogen-enriched blast furnace coke-packed beds.
