* Jul 27, 2024 According to Total H Index. BETA VERSION. Subject field ranking in world, region, country and university is beta version since subject field 'others' (762.001 scientists) profile whose branch cannot be determined, not yet edited or determined) is excluded, so the ranking will change as the others fields are edited. Please note that.
