dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Behaviour of the additive finite locus model [PDF]

, 1999
A finite locus model to estimate additive variance and the breeding values was implemented using Gibbs sampling. Four different distributions for the size of the gene effects across the loci were considered: i) uniform with loci of different effects, ii)

Photon polarization tensor at finite temperature and density in a magnetic field

Journal of High Energy Physics
We present analytical and numerical calculations for the photon polarization tensor at finite temperature and density in a constant magnetic field. We first discuss the tensor decomposition in the presence of the magnetic field, which breaks rotational ...

Pion dynamics in a soft-wall AdS-QCD model

Journal of High Energy Physics, 2022
Pseudo-Goldstone modes appear in many physical systems and display robust universal features. First, their mass m obeys the so-called Gell-Mann-Oakes-Renner (GMOR) relation f 2 m 2 = H σ ¯ $$ H\overline{\sigma} $$ , with f the Goldstone stiffness, H the ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Fluctuations at finite temperature and density [PDF]

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015), 2016
Fluctuations of conserved charges in a grand canonical ensemble can be calculated as derivatives of the free energy with respect to the respective chemical potential. They are directly related to experimentally available observables that describe the hadronization in heavy ion collisions.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Attractors without scaling: adiabatic hydrodynamization with and without inelastic scattering

Journal of High Energy Physics
We study the process of hydrodynamization in kinetic theories of gluons undergoing boost-invariant expansion using the Adiabatic Hydrodynamization (AH) framework. We study both number-conserving and non-conserving theories, and find that including number

Screening at finite temperature and density [PDF]

Proceedings of Critical Point and Onset of Deconfinement - 4th International Workshop — PoS(CPOD07), 2008
We present lattice QCD results on heavy quark free energies, extract from its temperature dependence entropy and internal energy contributions, and discuss the onset of medium effects that lead to screening of static quark-antiquark sources in a thermal medium.
