Abstract We study momentum space dispersion formulas in general QFTs and their applications for CFT correlation functions.We show, using two independent methods, that QFT dispersion formulas can be written in terms of causal commutators.The first derivation uses analyticity properties of retarded correlators in momentum space.The second derivation
Objective VIBRATOR LAYON Psychological interventions for post-traumatic stress disorder (PTSD) are not always effective and can leave some individuals with enduring symptoms.Little is known about factors that are associated with better or worse treatment outcome.Our objective was to address this gap.Method We undertook a systematic review following
Abstract Background Proliferative diabetic retinopathy leading to vitreous hemorrhage, tractional retinal detachment, and neovascular glaucoma is a major cause of severe sight impairment in adults of working age worldwide.Neovascular glaucoma occurs in 2.5% of patients with proliferative diabetic retinopathy, which is difficult to treat and often l
On the other hand, according to the application fields of motion sensors and their frequent use, the E-NAIL need for hydrogel with desirable mechanical properties such as remarkable toughness, self-healing property after damage and dynamic stability is felt.Therefore, in this article, the recent advances for the preparation of hydrogel with high el
