the category of verb as the nucleus of sentence has a significant importance in grammar. this grammatical category has specific semantic and syntactic characteristics in different languages. in role and reference grammar as a functional grammar, predicates are classified into five classes including states, activities, achievements, accomplishments and active-accomplishments. these five classes ...

2014 We study how the behaviour of an electron in d.c. electric or magnetic fields changes when this electron is simultaneously interacting with a high frequency electromagnetic wave. The new dynamical properties of the electron are described by an effective hamiltonian that we derive using a quantum description of the electromagnetic field and including relativistic corrections up to order 1/c...

We assess the validity of "microscopic" approaches of glass-forming liquids based on the sole knowledge of the static pair density correlations. To do so, we apply them to a benchmark provided by two liquid models that share very similar static pair density correlation functions while displaying distinct temperature evolutions of their relaxation times. We find that the approaches are unsuccess...
