Foundations of Wilson Lines and Loops From Basic Concepts to Gauge Field Reconstruction
Fortschritte der Physik, Volume 74, Issue 10, October 2026.Wilson lines and Wilson loops are reviewed as parallel transport observables in continuum gauge theory. Full holonomy data recover the local connection and curvature through short segment and small loop limits. Traced Wilson loops are gauge invariant but lose matrix information, so reconstruction requires a compatible lift constrained by trace ...

Mingling of the infrared and ultraviolet and the “cosmological constant” for interacting QFT in 2d
Journal of High Energy Physics, 2023 We propose a proper definition of the vacuum expectation value of the stress energy tensor 〈0| T μν | 0〉 for integrable quantum field theories in two spacetime dimensions, which is the analog of the cosmological constant in 4d.

LIPOTHERM: A Calibration Framework for GDGT Paleothermometry Based on Machine Learning
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract SST reconstruction from glycerol dialkyl glycerol tetraethers (GDGT) preserved in marine sediments is an important tool in quantitative paleoclimatology. These reconstructions require calibration frameworks that provide mapping between sediment GDGT data and temperature values.

Dimensional regularization and the renormalization group [PDF]
Nuclear Physics B, 1973 Abstract The behaviour of a renormalized field theory under scale transformations x → λx; p → p/λ can be found in a simple way when the theory is regularized by the continuous dimension method. The techniques proposed here have several applications in dimensionally regularized theories: short distance behaviour is expressed in terms of the single ...

Journal of High Energy Physics, 2022 For N $$ \mathcal{N} $$ = 1 SQED with N f flavors regularized by higher derivatives in the general ξ-gauge we calculate the three-loop anomalous dimension of the matter superfields defined in terms of the bare coupling constant and demonstrate its gauge ...

Factors Influencing the Emergence of Dependency Length Minimization in Neural Agent Simulations
Cognitive Science, Volume 50, Issue 10, October 2026.Abstract Given various grammatical options, language users prefer the word order choice that reduces the overall length of syntactic dependencies, a principle known as dependency length minimization (DLM). The origins of this preference remain an open question, particularly whether it originates from constraints on efficient information processing ...

FedLucra: Federated Learning With Loss‐Utility Controlled Robust Aggregation
Expert Systems, Volume 43, Issue 10, October 2026.ABSTRACT Federated learning enables collaborative model training without centralizing private data. However, conventional aggregation strategies generally determine client contributions primarily according to local data volume and do not directly consider differences in local model performance. To address this limitation, we propose FedLucra, a modular

, 1984 Many numerical predictions of experimental phenomena in particle physics are made possible by exploiting the discovery that simplifications can happen when phenomena are investigated on short distance and time scales.

Classical Renormalization of Codimension-two Brane Couplings [PDF]
, 2007 The curvature on codimension‐two and higher branes is not regular for arbitrary matter sources. Nevertheless, the low‐energy theory for an observer on such a brane should be well‐defined and independent to any regularization procedure.

Two-loop running in the bosonic SMEFT using functional methods
Journal of High Energy PhysicsThe next goalpost in precision calculations for physics beyond the Standard Model is determining the two-loop renormalization group (RG) equations in the Standard Model Effective Field Theory (SMEFT).
