Confidence Intervals for a Proportion Estimated From Pooled Samples Based on Firth's Corrected Score

Biometrical Journal, Volume 68, Issue 5, October 2026.
ABSTRACT Interval estimation of a proportion estimated from testing of pooled samples has been studied by a variety of researchers, who have examined both exact and asymptotic methods. Recent work in point estimation has seen the use of Firth's correction to maximum likelihood estimation to reduce bias effectively. We consider the Firth‐corrected score

COI DNA barcoding to differentiate Haemagogus janthinomys and Haemagogus capricornii (Diptera: Culicidae) mosquitoes

Acta Tropica
The genus Haemagogus (Diptera: Culicidae) includes species that are important vectors of pathogens such as the yellow fever virus. The accurate identification of these species is essential for the control of zoonoses. Females of Hg. capricornii and Hg. janthinomys are morphologically indistinguishable, which makes the use of alternative identification ...

Eugenol‐Derived Piperazine Mannich Bases as Selective Inhibitors of Mayaro Virus: In Vitro Antiviral Evaluation and Mechanistic Insights

Journal of Medical Virology, Volume 98, Issue 9, September 2026.
ABSTRACT Arboviruses represent an ongoing global health challenge, particularly in tropical regions where diseases caused by Chikungunya virus (CHIKV) and Mayaro virus (MAYV) continue to emerge. Given the absence of licensed antiviral therapies, the identification of effective small molecules remains critical.
