Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

A Mixture of Generalized Negative Binomial Distribution with Generalized Exponential Distribution

open access: yes, 2014
The negative binomial distribution has become increasingly popular as a more flexible alternative to Poisson distribution, especially when it is questionable whether the strict requirements for Poisson distribution could be satisfied.

Investigating the Heat Stability and Inactivation Conditions of Decapod Iridescent Virus 1 (DIV1)

open access: yesAnimal Research and One Health, EarlyView.
Heat treatment effectively inactivates decapod iridescent virus 1 (DIV1) under milder conditions than current WOAH recommendations. DIV1 infectivity was eliminated at 56°C for 30 min, 60°C for 15 min, or 70°C for 1 min, providing optimized heat treatment strategies for aquaculture biosecurity and seafood safety.

Quasi-negative binomial distribution: Properties and applications

open access: yes
In this paper, a quasi-negative binomial distribution (QNBD) derived from the class of generalized Lagrangian probability distributions is studied. The negative binomial distribution is a special case of QNBD. Some properties of QNBD, including the upper

Predictors of authorised, unauthorised and persistent absence among secondary school pupils in Scotland

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This article examines the factors associated with persistent absenteeism (an absence rate of 10% or higher) and authorised and unauthorised absence among secondary school pupils in Scotland. Using linked administrative data, the analysis focuses on secondary school stages S1–S6 in three academic years.

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities

open access: yesBiological Diversity, EarlyView.
Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

On the negative binomial distribution and its generalizations

open access: yes
It is shown that the negative binomial distribution NB(r,p) may arise out of an identical but dependent geometric sequence. Using a general characterization result for NB(r,p), based on a non-negative integer -valued sequence, we show that NB(2,p) may ...
