Correction to "Energy dissipation in multifrequency atomic force microscopy"

In the section "Energy dissipation" of the above manuscript, there is a typesetting error in the mathematical expressions after Equation 5. The correct form must be:

The energy balance of each decaying mode obtained from Equation 4 in the time window 0 < t < τ = 200 μs (see Figure 1) can be written as

where

i is the index of the mode, ΔK_i = 1/2 m_eq(v_i(0)² − v_i(τ)²) is the variation of kinetic energy, and ΔU_i = 1/2 k_i(z_i(0)² − z_i(τ)²) is the variation of elastic potential energy.
