In our calculations, we set κ = 1. The flowed field-strength tensor is defined as Gµν = ∂µBν − ∂ν Bµ + gB[Bµ, Bν ] , (2.3) the flowed covariant derivative in the adjoint representation is given by Dµ = ∂µ + gB[Bµ, · ] , (2.4) and ...
The natural choice is a McCrary test, ubiquitous in the RDD literature (McCrary, 2008), which checks for breaks in the density of the assignment variable at the kink. We extend this exercise by testing the first derivative of the density function, as proposed by Card et al. (2015). We...
The signal-to-noise ratio of the spectra was improved by recording the first derivative of P (dP/dH) using a lock-in technique. 1. Stanley, H. E. Introduction To Phase Transitions and Critical Phenomena (Oxford university press, Lodon, 1971). 2. Fisher, M. E. The theory of ...

Different ABA-dependent stomatal closure between drought cycles implies that acquisition of stomatal sensitivity may be a part of stress memory mechanism developed under given conditions. The regulatory role of ABA in the cell wall restructuring and growth regulation under low leaf potential was ...
