Uncertainty of Wave Spectral Shape and Parameters Associated with the Spectral Estimation
Journal of Marine Science and EngineeringThe uncertainty in estimating the wave spectrum from the records of wave elevation by heave–pitch–roll buoys is studied, considering the effects of the estimation method and the spectral resolution adopted in the process.

Characterization of a quantum phase transition in Dirac systems by means of the wave-packet dynamics
AIP Advances, 2012 We study the signatures of phase transitions in the time evolution of wave-packets by analyzing two simple model systems: a graphene quantum dot model in a magnetic field and a Dirac oscillator in a magnetic field.

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils
Advanced Science, EarlyView.Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

On the autocorrelation function of a trended series [PDF]
, 1985 Equations are derived for the autocorrelation function of a trended series. The special case of a linear trend is analysed in detail. It is shown that the zero of the autocorrelation function of a trended series is, in general, only dependent on the ...

Assessing Government Subsidies for Reducing Pesticide Use: A Meta‐Analysis
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT In the efforts being made by governments to reduce pesticide use, subsidies are an important instrument to encourage farmers to adopt more sustainable practices. Yet, their effectiveness remains uncertain due to diverse designs and contexts.

The limiting power of autocorrelation tests in regression models with linear restrictions
, 2004 It is well known that the Durbin-Watson and several other tests for first-order autocorrelation have limiting power of either zero or one in a linear regression model without an intercept, and tend to a constant lying strictly between these values when ...

The impact of institutional investors on risk and stock return autocorrelation in the context of the polish pension reform [PDF]
The main aim of this paper is to examine the relationship between the increasing share of institutional investors resulting from the pension reform in Poland and stock return autocorrelation as well as risk level on the Warsaw Stock Exchange. The problem
