  abstract = {{A}n improvement of the {D}avydov's model for energy transfer in alpha-helix protein is proposed. {U}sing hyperbolic cosine potential type to model hydrogen bond potential, we have obtained from the adiabatic approximation, a discrete nonlinear {S}chrodinger equation with inverse hyperbolic sine nonlinearity. {U}sing the two-dimensional discrete map approach, we have found a linearly stable intrinsic localized mode of the corresponding developed equation. {M}obility of the intrinsic localized mode was achieved by moving the local impurity hypothesized as the anomalous band energy. {T}he reactivity of the discrete breather under thermal noise was studied numerically with the {L}angevin's approach. {I}t was shown that the intrinsic localized mode in the developed model keep its shape longer under thermal bath.},
