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. 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 ...

3. 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 ...

4. Influence, inertia, and independence: a diffusion model for temporal social networks 

   Marmulla, Gordana; Brandes, Ulrik (2024)

   The Journal of Mathematical Sociology

   In this work, we propose a diffusion model for temporal social networks and relate it to other well-known models of social influence by investigating its formal properties. The model establishes dyadic influence weights based on two antagonistic components: the susceptibility to be influenced (or, conversely, inertia with respect to the status quo) and becoming independent of prior influence. The proposed model generalizes the Friedkin-Johnsen ...

5. Gender and reactions to speeches in German parliamentary debates 

   Ash, Elliott; Kruemmel, Johann; Slapin, Jonathan B. (2024)

   American Journal of Political Science

   Are nonverbal reactions during parliamentary debate gendered? Do male and female members of parliament (MPs) experience applause or jeering differently? In short, yes, and the gendered nature of a speech matters. Using an original corpus of over 544,000 speeches given in German state parliaments, we first estimate the gendered nature of parliamentary speeches and then examine how reactions to speeches given by male and female MPs differ. ...
