From Simulation to Experiment: Multi-Code Modelling and Validation of Carbon-11 Production Using Natural Boron Targets

This study validates the 11B(p,n)11C reaction for producing high-purity Carbon-11 using natural boron targets by integrating TALYS simulations with TR-19 cyclotron experiments, demonstrating that boron nitride yields the highest activity (12.37 GBq) and confirming the method's suitability for future laser-driven production at ELI-NP.

Impact of electrometer sensitivity variation on absorbed dose-to-water determination: a multicenter uncertainty study

This multicenter study demonstrates that using a common electrometer calibration coefficient instead of individual primary standards laboratory coefficients introduces a negligible increase in uncertainty, thereby supporting its validity for routine quality assurance in absorbed dose-to-water determination.

Deformation Due to a Pair of Infinite and a Pair of infinite-finite planar faults in Fractional Standard Linear Solid

This paper employs fractional calculus, Laplace transformation, and modified Green's function techniques to model and analyze the displacement, stress, and strain interactions between pairs of infinite and infinite-finite creeping strike-slip faults within a fractional standard linear solid viscoelastic half-space, revealing that the influence of one creeping fault on another intensifies with higher fractional derivative orders.

Error correction advances the point of no return in a radical-pair model of decision-making

This paper proposes that error correction in a radical-pair model of decision-making, anchored in cryptochrome and utilizing open-system quantum tools, paradoxically advances the point of no return by preserving the decision signal to reach the motor threshold sooner, thereby suggesting that increased quantum coherence leads to faster, less revisable actions rather than greater freedom.

Comprehensive Analysis of Burnup-Driven Fission Product Evolution and Radiological Releases in VVER-1200 in Bangladesh’s First Nuclear Power Plant

This study analyzes the burnup-dependent evolution of radionuclide inventories in the VVER-1200 reactor at Bangladesh's Rooppur Nuclear Power Plant up to 19.808 MWD/kg, revealing that higher burnup significantly increases key fission product and actinide concentrations, thereby providing critical data for safety analysis and emergency preparedness despite a 15–50% underestimation compared to NUREG-1940 reference values.
