Time Scales in Long GRBs

, 2001
We analyze a sample of bright long bursts and find that the pulses duration have a lognormal distribution while the intervals between pulses have an excess of long intervals (relative to lognormal distribution).

Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...

Forecasting New Employment Using Nonrepresentative Online Job Advertisements With an Application to the Italian and EU Labor Market

Journal of Forecasting, EarlyView.
ABSTRACT Using online job advertisement data improves the timeliness and granularity depth of analysis in the labor market in domains not covered by official data. Specifically, its variation over time may be used as an anticipator of official employment variations.

GZK cutoff distortion due to the energy error distribution shape

, 2006
The observed energy spectrum of ultra high energy cosmic rays (UHECR) is distorted by errors in the energy reconstruction. Here we show that if the shape of the error distribution is lognormal, the high end of the cosmic ray spectrum will be distorted ...

Inconsistency of the Capital Asset Pricing Model in a Multi‐Currency Environment

International Journal of Finance &Economics, EarlyView.
ABSTRACT The capital asset pricing model (CAPM) is a widely adopted model in asset pricing theory and portfolio construction because of its intuitive nature. One of its main conclusions is that there exists a global market portfolio that each rational investor should hold in proportion to the risk‐free asset. In this paper, we demonstrate theoretically

Scaling of Fracture Strength in Disordered Quasi-Brittle Materials

, 2004
This paper presents two main results. The first result indicates that in materials with broadly distributed microscopic heterogeneities, the fracture strength distribution corresponding to the peak load of the material response does not follow the ...

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

Goodbye LogNormal Distribution

, 2022
AbstractThe R-scripts presented and developed in the prior chapters assumed an investment return generating process that is both static and LogNormal, via the basic function. Indeed, had this work been done in the 1970s, or perhaps the 1670s when national (versus natural) tontines were first launched, that might have been sufficient.

Managing water resources and aquatic invaders: Public preferences, stakeholder perspectives, and policy implications

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Aquatic invasive species threaten water resources by reducing biodiversity, disrupting ecosystems, and impeding recreation. Managing these invaders is challenging due to public concerns over chemical control methods and conflicting stakeholder preferences.

Essential and toxic elements intake from botanical extracts: a probabilistic risk–benefit evaluation within the Italian dietary context

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 ...
