  We have conducted a comprehensive and systematic study of the proton
radioactivity and $\alpha$-decay half-lives of neutron-deficient nuclei. This
investigation involved the utilization of various Proximity potentials and also
considered the incorporation of thermal effects. For the half-life
calculations, we employed both temperature-independent and
temperature-dependent interaction potentials. We observed that proton
radioactivity serves as the dominant mode of decay for nuclides situated very
close to the proton drip-line. We explored a universal curve that examines the
correlation between the decimal logarithm of experimental half-lives and the
negative decimal logarithm of the penetrability for both proton radioactivity
and $\alpha$-decay.
