Modelando la distribución del número de co-autores por artículo Modeling the distribution of co-authorships by paper

Investigación Bibliotecológica: Archivonomía, Bibliotecología e Información, 2011
Este artículo explora la modelación del número de autores que colaboran en la publicación de un artículo. Con ese fin se analizaron la distribución geométrica, la distribución Poisson truncada, la distribución Poisson lognormal y la distribución Gauss ...

Time‐resolved coherent X‐ray scattering analysis of nanorod colloids: dynamics and photon‐statistical effects in angular X‐ray cross‐correlation analysis

Journal of Synchrotron Radiation, EarlyView.
A statistical framework combining angular X‐ray cross‐correlation analysis, principal component analysis and photon‐counting simulations is presented for evaluating the detectability of orientational fluctuations in time‐resolved coherent X‐ray scattering experiments.Understanding the dynamic fluctuations of anisotropic particles is essential for ...

Influence of Public Bus Driver’s Driving Behaviors on Passenger Fall Incidents: An Analysis Using Digital Tachograph Data

Journal of Advanced Transportation, 2022
Owing to the low occurrence of public transport accidents, most existing studies have focused on improving the traffic safety of passenger cars. However, traffic accidents related to public transport should also be investigated for the safety of public ...

Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

Journal of Animal Ecology, EarlyView.
Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...

Mid-Epidemic Forecasts of COVID-19 Cases and Deaths: A Bivariate Model Applied to the UK

Interdisciplinary Perspectives on Infectious Diseases, 2021
Background. The evolution of the COVID-19 epidemic has been accompanied by efforts to provide comparable international data on new cases and deaths. There is also accumulating evidence on the epidemiological parameters underlying COVID-19.

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest

Integrative Zoology, EarlyView.
Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

A Lognormal Model for Insurance Claims Data

Revstat Statistical Journal, 2006
In the insurance area, especially based on observations of the number of claims, N(w), corresponding to an exposure w, and on observations of the total amount of claims incurred, Y (w), the risk theory arises to quantify risks and to fit models of ...

Integrative phylogenomics uncovers hidden diversity and repeated cave colonizations in Dinaric pseudoscorpions

Cladistics, EarlyView.
Abstract Subterranean ecosystems harbour exceptional biodiversity shaped by adaptation to extreme environments, yet remain poorly explored. Cave organisms, restricted to small, isolated populations, are extinction‐prone, making integrative species delimitation essential for biodiversity assessment and conservation.

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...
