Fiber Link Stabilization with a Multicore Fiber Amplifier
arXiv:2602.21373v1 Announce Type: new Abstract: We study the use of separate cores of a multicore erbium-doped fiber amplifier (MC-EDFA) in a noise-canceled link for ultrastable optical…
Structurally Conditioned Diffusion Reproduces Skills-Based Stratification
arXiv:2602.21369v1 Announce Type: new Abstract: Occupational hierarchies remain strikingly stable even as job content changes rapidly. We ask whether skill requirements propagate directionally along the wage…
Towards single-shot coherent imaging via overlap-free ptychography
arXiv:2602.21361v1 Announce Type: new Abstract: Ptychographic imaging at synchrotron and XFEL sources requires dense overlapping scans, limiting throughput and increasing dose. Extending coherent diffractive imaging to…
Novel Asymmetrical High-Resolution and High-Sensitivity Brain Dedicated PET system: Design optimization and performance evaluation
arXiv:2602.21354v1 Announce Type: new Abstract: Objective. This study investigates the best achievable performance of a brain-dedicated PET system with high resolution and sensitivity by evaluating different…
Efficient and Accurate Method for Separating Variant Components from Invariant Background and Component Model Fusion for Fast RFIC Design Space Exploration
arXiv:2602.21335v1 Announce Type: new Abstract: The design of RFIC often involves exploring a large number of design variations in an invariant background composed of the processing…
De-Idealizing De-Idealization: Beyond Full Reversal
arXiv:2602.21324v1 Announce Type: new Abstract: There is a question of whether de-idealization is needed for justified use of — for ‘checking’ — idealizations. We argue that…
Kolmogorov Scaling for Total Energy and Cross Helicity in Magnetohydrodynamic Turbulence
arXiv:2602.21271v1 Announce Type: new Abstract: The problem of scaling in isotropic magnetohydrodynamic (MHD) turbulence has remained unresolved, with competing predictions of $k^{-5/3}$ (Kolmogorov) and $k^{-3/2}$ (Iroshnikov-Kraichnan)…
Surrogate neutron-capture studies with fission detection in inverse kinematics at the ESR storage ring
arXiv:2602.21256v1 Announce Type: new Abstract: The NECTAR (Nuclear rEaCTions At storage Rings) experiment at the ESR heavy-ion storage ring at GSI Darmstadt is dedicated to surrogate…
Physics Constrained Neural Collision Operators for Variable Hard Sphere Surrogates and Ab Initio Angle Prediction in Direct Simulation Monte Carlo
arXiv:2602.21244v1 Announce Type: new Abstract: The Direct Simulation Monte Carlo (DSMC) method is the gold standard for non-equilibrium rarefied gas dynamics, yet its computational cost can…
Quantum and Classical mechanics vs QFT
arXiv:2602.21243v1 Announce Type: new Abstract: 15 years ago Dmitry Diakonov wrote the paper “Towards lattice-regularized Quantum Gravity”, arXiv:1109.0091. In his approach, gravity with metric and tetrads…
