A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Relationship between the behaviour of sows at 6 months old and the behaviour and performance at farrowing

open access: yesAnimal, 2009
Piglet crushing remains a major problem in pig production. Reduced crushing might be obtained through genetic selection on sow behavioural traits. The aim of the study was to assess the relationship between behavioural responses at 6 months of age ...

Financial Time Series Uncertainty: A Review of Probabilistic AI Applications

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Probabilistic machine learning models offer a distinct advantage over traditional deterministic approaches by quantifying both epistemic uncertainty (stemming from limited data or model knowledge) and aleatoric uncertainty (due to inherent randomness in the data), along with full distributional forecasts.

Maximum Entropy: Clearing up Mysteries

open access: yesEntropy, 2001
: There are several mystifications and a couple of mysteries pertinent to MaxEnt. The mystifications, pitfalls and traps are set up mainly by an unfortunate formulation of Jaynes' die problem, the cause célèbre of MaxEnt.

Limited drought tolerance in the neotropical seasonally dry forest plants impairs future species richness

open access: yesPlant Biology, EarlyView.
Global climate change will likely modify the plant assemblages of the Neotropical seasonally dry forest based on the physiological capabilities of the species. Abstract Neotropical seasonal dry forest (NSDF) is one of the most threatened ecosystems according to global climate change predictions.

Protease‐mediated maturation of M‐PMV reverse transcriptase into a functional heterodimer

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Reverse transcriptase (RT) of retroviruses orchestrates viral replication, yet its structural diversity remains poorly understood. Well‐studied RTs, such as those from HIV‐1, murine leukemia virus, and avian myeloblastosis virus, were characterized decades ago, but less prominent retroviruses have escaped detailed analysis.

Modelling the distribution of the proboscis monkey (Nasalis larvatus) in Sabah (Borneo) based on remotely sensed high-resolution global cloud dynamics

open access: yesTheriologia Ukrainica
Proboscis monkeys, Nasalis larvatus (Wurmb, 1787), are indigenous to the island of Borneo and are considered one of its most emblematic species. Today the conservation status of this primate is classified as Endangered on the IUCN Red List and listed ...
