More adequate probability distributions to represent the saturated soil hydraulic conductivity
Scientia Agricola, 2002 The saturated soil hydraulic conductivity (Ksat) is one of the most relevant variables in studies of water and solute movement in the soil. Its determination in the laboratory and in the field yields high dispersion results, which could be an indication ...

Brain Pathology, EarlyView.The efficacy of the novel anti‐tau active immunotherapy, p5555kb, was tested using two mouse models of tau pathology. p5555kb inoculation increased the survival rate and reduced tau pathology in tau‐overexpressing P301L mice and decreased tau seeding in the brains of C57BL/6 mice injected with human‐purified Alzheimer's disease tau.

Distance of movement in three threatened butterfly species
Ecological Entomology, EarlyView.Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

Option Pricing with Normal Mixture Returns: Modelling Excess Kurtosis and Uncertanity in Volatility [PDF]
his paper addresses the problem of uncertainty in volatility, and how this affects option prices. The volatility uncertainty adjustment to Black-Scholes option prices is quantified in this paper using a normal mixture model for the distribution of ...

The Economic History Review, EarlyView.Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...
