Domyn-Small: A European 10B Reasoning Language Model
Simone Angarano, Francesco Bertolotti, Federico D'Ambrosio +7
We introduce Domyn-Small, a 10-billion-parameter open-weight reasoning language model released under the MIT license. Domyn-Small is the product of an initial pre-training phase on…
Efficient structural relaxation of polycrystalline graphene models
Federico D'Ambrosio, Joris Barkema, Gerard T Barkema
Large samples of experimentally produced graphene are polycrystalline. For the study of this material, it helps to have realistic computer samples that are also polycrystalline. A…
Discontinuous evolution of the structure of stretching polycrystalline graphene
Federico D'Ambrosio, Vladimir Juričić, Gerard T. Barkema
Polycrystalline graphene has an inherent tendency to buckle, i.e. develop out-of-plane, three-dimensional structure. A force applied to stretch a piece of polycrystalline graphene…
Dynamic Sampling from a Discrete Probability Distribution with a Known Distribution of Rates
Federico D'Ambrosio, Hans L. Bodlaender, Gerard T. Barkema
In this paper, we consider several efficient data structures for the problem of sampling from a dynamically changing discrete probability distribution, where some prior information…
Thermal response of a Fermi-Pasta-Ulam chain with Andersen thermostats
Federico D'Ambrosio, Marco Baiesi
The linear response to temperature variations is well characterised for equilibrium systems but a similar theory is not available, for example, for inertial heat conducting systems…
