Abstract Dressed here states were proposed to define the infrared (IR) finite S-matrix in QED or gravity.We show that the original Kulish-Faddeev dressed states are not enough to cure the IR divergences.To illustrate this problem, we consider QED with background currents (Wilson lines).This theory is exactly solvable but shares the same IR problems
Abstract Matrix Metalloproteases (MMPs) are an important family of proteases that play crucial roles in key cellular and disease processes.Therefore, MMPs constitute important targets for drug design, development and delivery.Advanced proteomic technologies have hobbit door for sale identified type-specific target substrates; however, the complete
Aim and Background: Because of the similarity between some signs of panic disorder (PD) and COVID-19, individuals with PD like individuals with obsessive-compulsive disorder (OCD) are vulnerable to negative outcomes of the pandemic.However, previous studies did not adequately address the impacts of COVID-19 on this disorder.Regarding the importance
