Gibrat's law for cities: uniformly most powerful unbiased test of the Pareto against the lognormal
, 2009 We address the general problem of testing a power law distribution versus a log-normal distribution in statistical data. This general problem is illustrated on the distribution of the 2000 US census of city sizes.

Consumers' valuation for cultured meat: A multi‐city choice experiment in China
Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Despite the rising interest in cultured meat, there remains scant information on whether consumers would value it. This study evaluated consumers' willingness‐to‐pay (WTP) for cultured chicken and examined how information affects WTP. Using a choice experiment with a total of 571 samples, the results found that consumers are unwilling to pay a

On the Power-Law Tail in the Mass Function of Protostellar Condensations and Stars
, 2003 We explore the idea that the power-law tail in the mass function of protostellar condensations and stars arises from the accretion of ambient cloud material on to a condensation, coupled with a nonuniform (exponential) distribution of accretion lifetimes.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Botanical extracts are widely consumed for their claimed health benefits, yet their safety profile with respect to chronic consumption remains poorly characterized. Understanding the potential health risks associated with their inorganic content is a crucial issue for ensuring safe use, along with a characterization of the ...

Prevention of postpartum haemorrhage: a distributional approach for analysis
Reproductive Health, 2018 Background There is empirical evidence that measured postpartum blood loss has a lognormal distribution. This feature can be used to analyze events of the type ‘blood loss greater than a certain cutoff point’ using a lognormal approach, which takes into ...

Solar-wind predictions for the Parker Solar Probe orbit
, 2017 The scope of this study is to model the solar-wind environment for the Parker Solar Probe's unprecedented distances down to 9.86 Rs in its mission phase during 2018-2025.

An Exact Method for Reliable Shortest Path Problems With Correlation
Networks, EarlyView.ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

Extreme Value Laws for Superstatistics
, 2014 We study the extreme value distribution of stochastic processes modeled by superstatistics. Classical extreme value theory asserts that (under mild asymptotic independence assumptions) only three possible limit distributions are possible, namely: Gumbel,

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Sharp force trauma (SFT) is the main criterion used to identify chop mark butchery in zooarchaeology, yet its reliability as a diagnostic feature has not been systematically tested. Chop marks reflect both cutting and fracturing processes and exhibit characteristics of both sharp and blunt trauma.

Oikos, EarlyView.Light is a key driver of understory plant diversity, also important for seed germination, yet its effect on forests soil seed bank diversity remains underexplored. This study assessed the impact of both light availability and spatio‐temporal heterogeneity on soil seed bank diversity.
