We consider a special class of binomial sums involving harmonic numbers and we prove three identities by using the elementary method of the partial fraction decomposition. Some applications to infinite series and congruences are given.

Our daily activities increasingly rely on remote resources and services — specifically, on interactions between different, remotely located parties. Because these parties might (and sometimes should) know little about each other, digital identities — electronic representations of individuals’ or organizations’ sensitive information — help introduce them to each other and control the amount of i...
