Calibration limited quantum advantage in dose constrained biomolecular absorption spectroscopy

This paper establishes that while quantum optical probes can theoretically enhance biomolecular absorption spectroscopy, their practical advantage in concentration estimation is fundamentally limited by spectral calibration uncertainty, necessitating specific design criteria to balance photon budget allocation against calibration precision.

Convolutional neural network versus persistence for forecasting syndrome rate threshold crossings

This paper demonstrates that while short-term threshold crossings in quantum error correction are predictable under slow calibration drift, a convolutional neural network offers no accuracy advantage over a simple last-cycle persistence baseline, highlighting the necessity of trajectory-disjoint evaluation and robust temporal baselines for assessing machine learning monitors.

A fictitious-source formulation for direct numerical simulation of turbulent boundary layers in prescribed pressure gradients

This paper introduces and validates a fictitious-source formulation that enables the direct numerical simulation of compressible turbulent boundary layers under prescribed streamwise pressure gradients within a flat Cartesian domain, effectively decoupling pressure-gradient effects from wall geometry while accurately reproducing key flow characteristics.

Segmentation of a three-dimensional crack front under mode I+III: closed-form predictions tested by a Born-weight dual boundary element–peridynamics coupling

This paper presents closed-form predictions and a Born-weight dual boundary element–peridynamics coupling to determine the characteristic spacing and tension-driven energy share of tilted facets formed by a three-dimensional crack front under mixed mode I+III loading, thereby resolving the material length scale left open by scale-free elastic theories.

Modeling of In-Situ Nitrogen Alloying in SS316 during Laser Directed Energy Deposition

This study presents a coupled thermal–thermodynamic–kinetic model that predicts the extent of in-situ nitrogen alloying in AISI 316 during laser directed energy deposition, revealing that nitrogen uptake is kinetically limited by surface absorption dynamics rather than thermodynamic equilibrium and is strongly influenced by process parameters and dissolved oxygen.
