Velocity Fields in Non--Gaussian Cold Dark Matter Models [PDF]
, 1994 We analyse the large--scale velocity field obtained by N--body simulations of cold dark matter (CDM) models with non--Gaussian primordial density fluctuations, considering models with both positive and negative primordial skewness in the density ...

Improved decision support for engine-in-the-loop experimental design optimization [PDF]
, 2009 Experimental optimization with hardware in the loop is a common procedure in engineering and has been the subject of intense development, particularly when it is applied to relatively complex combinatorial systems that are not completely understood, or ...

Unjamming of Granular Packings due to Local Perturbations: Stability and Decay of Displacements
, 2007 We study the mechanical response generated by local deformations in jammed packings of rigid disks. Based on discrete element simulations we determine the critical force of the local perturbation that is needed to break the mechanical equilibrium and ...

Ultracapacitor storage enabled global MPPT for photovoltaic central inverters [PDF]
, 2017 In most large scale grid-tied photovoltaic (PV) plants, central inverter configurations are used, mainly due to higher efficiency and lower cost per kW.

Analysis of Modulated Multivariate Oscillations
, 2011 The concept of a common modulated oscillation spanning multiple time series is formalized, a method for the recovery of such a signal from potentially noisy observations is proposed, and the time-varying bias properties of the recovery method are derived.

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 ...
