Time-Fractional Phase Field Model of Electrochemical Impedance

open access: yesFractal and Fractional, 2021
In this paper, electrochemical impedance responses of subdiffusive phase transition materials are calculated and analyzed for one-dimensional cell with reflecting and absorbing boundary conditions.

Interpolation process between standard diffusion and fractional diffusion [PDF]

open access: yes, 2017
We consider a Hamiltonian lattice field model with two conserved quantities, energy and volume, perturbed by stochastic noise preserving the two previous quantities.

Diffusion Model Alignment Using Direct Preference Optimization [PDF]

open access: yesComputer Vision and Pattern Recognition, 2023
Large language models (LLMs) are fine-tuned using human comparison data with Reinforcement Learning from Human Feedback (RLHF) methods to make them better aligned with users' preferences. In contrast to LLMs, human preference learning has not been widely

Mediación editorial y valor agregado: La obra de Jaime Saenz desde las redes sociales del pasado

open access: yesBolivian Studies Journal, 2021
Una mirada crítica al lugar que ocupa Jaime Saenz en el panorama de la traducción de literaturas extranjeras podría clarificar la construcción de su imagen de escritor tanto en Bolivia como en los países en los que se lo ha traducido. ¿Cómo se ve la obra

Self-diffusion of polymers in cartilage as studied by pulsed field gradient NMR [PDF]

open access: yes, 2002
Pulsed field gradient (PFG) nuclear magnetic resonance (NMR) was used to investigate the self-diffusion behaviour of polymers in cartilage. Polyethylene glycol and dextran with different molecular weights and in different concentrations were used as ...

Planning with Diffusion for Flexible Behavior Synthesis [PDF]

open access: yesInternational Conference on Machine Learning, 2022
Model-based reinforcement learning methods often use learning only for the purpose of estimating an approximate dynamics model, offloading the rest of the decision-making work to classical trajectory optimizers.

Truncated correlation photoacoustic coherence tomography: An axial resolution enhancement imaging modality

open access: yesPhotoacoustics, 2021
In this report we present a novel photoacoustic (PA) modality using pulsed chirp excitation at a fixed wavelength and spectral analysis based on frequency-domain (FD) processing.

MICRA: an automatic pipeline for fast characterization of microbial genomes from high-throughput sequencing data

open access: yesGenome Biology, 2017
The increase in available sequence data has advanced the field of microbiology; however, making sense of these data without bioinformatics skills is still problematic.
