On the Convergence to the Non-equilibrium Steady State of a Langevin Dynamics with Widely Separated Time Scales and Different Temperatures
Nicolas Macris, Emanuele Mingione, Diego Alberici
We study the solution of the two-temperature Fokker-Planck equation and rigorously analyse its convergence towards an explicit non-equilibrium stationary measure for long time and two widely separated time scales. The exponential rates of convergence are e ...
Cham2024Comparison of Three Imputation Methods for Groundwater Level Timeseries
This study compares three imputation methods applied to the field observations of hydraulic head in subsurface hydrology. Hydrogeological studies that analyze the timeseries of groundwater elevations often face issues with missing data that may mislead bot ...
MDPI2023Weakly nonlinear versus semi-linear models of the nonlinear evolution of the centrifugal instability
We carry out a weakly nonlinear analysis of the centrifugal instability for a columnar vortex in a rotating fluid, and compare the results to those of the semi-linear model derived empirically by Yim et al. (J. Fluid Mech., vol. 897, 2020, A34). The asympt ...
CAMBRIDGE UNIV PRESS2023Disentangling the effects of climate change and reoligotrophication on primary production in a large lake
Alfred Johny Wüest, Hugo Nicolás Ulloa Sánchez, Shubham Krishna, Emile Barbe
Climate change and reduction in nutrient loads have significant effects on primary production and phytoplankton growth dynamics. Since in the last few decades in many regions, nutrients in lakes were reduced simultaneously as the climate changed. Yet, it r ...
SPRINGER BASEL AG2023How accurate are flux-tube (local) gyrokinetic codes in modeling energetic particle effects on core turbulence?
Olivier Sauter, Alberto Bottino, Emanuele Poli
Flux-tube (local) gyrokinetic codes are widely used to simulate drift-wave turbulence in magnetic confinement devices. While a large number of studies show that flux-tube codes provide an excellent approximation for turbulent transport in medium-large devi ...
IOP Publishing Ltd2023DiGress: Discrete Denoising diffusion for graph generation
Pascal Frossard, Volkan Cevher, Igor Krawczuk, Bohan Wang, Clément Arthur Yvon Vignac
This work introduces DiGress, a discrete denoising diffusion model for generating graphs with categorical node and edge attributes. Our model utilizes a discrete diffusion process that progressively edits graphs with noise, through the process of adding or ...
2023Divide-and-conquer one-step simulator for the generation of synthetic households
Michel Bierlaire, Marija Kukic
This paper presents a novel simulation approach for generating synthetic households, addressing several literature gaps from the methodological viewpoint. The generation of hierarchical datasets such as complete households is challenging since it must guar ...
2023Exploiting Marginal Stability in Slow-Fast Quasilinear Dynamical Systems
The accurate investigation of many geophysical phenomena via direct numerical simulations is computationally not possible nowadays due to the huge range of spatial and temporal scales to be resolved. Therefore advances in this field rely on the development ...
EPFL2022Monotonicity in the trip scheduling problem
Nikolaos Geroliminis, Raphael Ali Francis Lamotte
The equilibrium of the archetypal morning commute problem with alpha -,B - gamma preferences has been shown to be unstable with various rational adjustment mechanisms, under both continuous and discrete day-to-day dynamics. It is not clear however whether ...
