We reexamine a renormalizable model of a fermionic dark matter with a gauge singlet Dirac fermion and a real singlet scalar which can ameliorate the scalar mass hierarchy problem of the Standard Model (SM).Our model setup is the minimal extension of the SM for which a realistic dark matter (DM) candidate is provided and the cancellation of one-loop
Energy is the basis of human development and the impetus of society progress.There are three sources of energy: energy of celestial body outside the Earth, the Earth energy and energy of interaction between the Earth and other celestial bodies.Meanwhile, there are three scales of co-evolution: the evolution of the Sun-Earth-Moon system on an ultra-
Blepharokeratoconjunctivitis secondary to ocular demodicosis in the pediatric population is often neglected and may result in a serious sight-threatening condition.In severe cases, it can lead to corneal perforation necessitating urgent corneal transplantation.However, the shortage and high cost of T-Shirt donor corneas is the foremost limitation o
