Many authors focused on coupled fixed point theory and proved remarkable results (see [4 17]).
After this remarkable contribution, many authors focused on partial metric spaces and its topological properties (see, e.g. [3]-[8]).
In recent years, many authors focused attention on constructing the fixed point of Bregman nonlinear operators by utilizing the Bregman distance and the Bregman projection, see [18 23] and the references therein.
Recently, due to the difference analog of the lemma on the logarithmic derivative given by Halburd and Korhonen in [5], and Chiang and Feng in [6] independently, many authors focused their interest on the complex difference analogs of Nevanlinna theory and complex difference equations (see [5 13]).
Recently, in a linear setting, many authors focused on the existence of solutions to equilibrium problems for vector mappings; see, for example, Ansari and Yao [6], Ansari and Flores-Bazán [7], Fu [8], Fu and Wan [9], Khan [10], Khan et al. [11], Khan and Chen [12], Hou et al. [13], Iusem and Sosa [14], Chen et al. [15], Kassay et al. [16], and the authors referenced by their works.
Many authors focused their research or papers on differential diagnosis in dementia.
Many authors focused their attention on the posttraumatic neuroendocrine dysfunction in order to achieve a correlation between hormones blood level and TBI outcomes.
Prior to the 1990's, many authors focused significant attention to the pre-foveolar vitreous cortex and its associated traction as playing a primary role in the etiology of idiopathic macular holes[ 2, 3, 6- 10].
