 Over the last few years, characterizing the nature of the spin dynamics
 at the interface has garnered much attention.
 A key contribution in this effort is the generalization of the standard theoretical approach
-of calculating the nonlocal magnetoresistance with and without the magnetic field
-\cite{PhysRevB.80.214427, PhysRevB.67.052409}
-to include the contact resistance.
+of calculating the nonlocal magnetoresistance with and without the magnetic field.
+Recent efforts study the effect of including the contact resistance
+\cite{PhysRevB.80.214427, PhysRevB.67.052409},
+and alternatively relaxing the normally infinite boundary conditions
+in favor of a finite channel size
+\cite{1404.6276v1}.
 The approach relies on numerically solving the Bloch equation
 to generate Hanle precession curves and then fitting observed data.
-In this paper, we present the closed form expression for the precession curves
-and analytically discuss the various parameters regimes that show qualitatively different behaviors.

+In this paper, we present the closed form expression
+for the precession curves with finite contact resistance,
+and analytically discuss the various parameters regimes
+that show qualitatively different behaviors.
 The fits to data reproduce the results in the literature
 and provide a means to understand the effect of the contacts
 which were previously obtained by numerical simulations.
