1. Extreme vortex pinning in the noncentrosymmetric superconductor CePt3Si 

   Miclea, Corneliu F.; Mota, Ana C.; Nicklas, Michael; et al. (2010)

   Physical Review B

   We report on the vortex dynamics of a single crystal of the noncentrosymmetric heavy-fermion superconductor CePt3Si. Decays of the remnant magnetization display a logarithmic time dependence with rates that follow the temperature dependence expected from the Kim-Anderson theory. The creep rates are lower than observed in any other centrosymmetric superconductor and are not caused by high critical currents. On the contrary, the critical ...

2. MICROPLASTIC IN SOIL - WATERDYNAMICS, HYDROPHOBICITY, AND INTERACTIONS 

   Cramer, Andreas (2024)

   Soils are considered as large sinks of microplastic (MP, diameter < 5 mm). Sources of MP contamination are identified as mismanagement of plastic containing waste, the use of plastics in agriculture as well as the neglected life cycle of plastic containing products. The long-range transport of airborne MP, its subsequent deposition and the degradation of larger plastic fragments are a potential source and pathway of MP input into soils. ...

3. Stability Certificates for Receding Horizon Games 

   Hall, Sophie (2024)

   Game-theoretic MPC (or Receding Horizon Games) is an emerging control methodology for multi-agent systems that generates control actions by solving a dynamic game with coupling constraints in a receding-horizon fashion. This control paradigm has recently received an increasing attention in various application fields, including robotics, autonomous driving, traffic networks, and energy grids, due to its ability to model the competitive ...

4. Improving the structure of a hydrological model to forecast catchment response to intense rainfall 

   Astagneau, Paul C.; Bourgin, Francois; Andreassian, Vazken; et al. (2024)

   LHB-HYDROSCIENCE JOURNAL

   We compared the flood forecasts issued by a model used by operational services in France (GRP) and by a model developed to improve the simulation of floods resulting from intense rainfall (GR5H_RI). We selected 10,652 flood events from 19 years of hourly data available for 229 French catchments. The models were combined with a state-updating procedure to produce forecasts at 3, 6, 12 and 24 h lead times. Results indicate that the GR5H_RI ...

5. Infinite-width limit of deep linear neural networks 

   Chizat, Lenaic; Colombo, Maria; Fernandez-Real, Xavier; et al. (2024)

   COMMUNICATIONS ON PURE AND APPLIED MATHEMATICS

   This paper studies the infinite-width limit of deep linear neural networks (NNs) initialized with random parameters. We obtain that, when the number of parameters diverges, the training dynamics converge (in a precise sense) to the dynamics obtained from a gradient descent on an infinitely wide deterministic linear NN. Moreover, even if the weights remain random, we get their precise law along the training dynamics, and prove a quantitative ...
