Fluctuation-response relation in turbulent systems
, 2001 We address the problem of measuring time-properties of Response Functions (Green functions) in Gaussian models (Orszag-McLaughin) and strongly non-Gaussian models (shell models for turbulence). We introduce the concept of {\it halving time statistics} to

Investigating the effect of PID controller on inertial response in doubly fed induction generator (DFIG) [PDF]
, 2016 The increasing penetration of wind generation impacts the reliability and stability of power systems. This paper investigates and analyses the effect of PID controller parameters on the inertial response of a doubly fed induction generator (DFIG) wind ...

Causal particle detectors and topology
, 2005 We investigate particle detector responses in some topologically non-trivial spacetimes. We extend a recently proposed regularization of the massless scalar field Wightman function in 4-dimensional Minkowski space to arbitrary dimension, to the massive ...

Delivering combined droop and inertial response from wind plant for power system frequency stability
The Journal of Engineering, 2019 As wind penetration level into power systems increases, provision of frequency support from wind plant is anticipated to become a requirement in grid codes.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

, 2017 We consider the excitation of a finite-length inertial Unruh detector in the Minkowski vacuum with an adiabatic switch on of the interaction in the infinite past and a sudden switch off at finite times, and obtain the excitation probability via a ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
