Article Abstract
Malaria infection is often accompanied by periodic fevers, triggered by synchronous cycles of parasite replication within the host. The degree of synchrony in parasite development influences the efficacy of drugs and immune defenses and is therefore relevant to host health and infectiousness. Synchrony is thought to vary over the course of infection and across different host-parasite genotype or species combinations, but the evolutionary significance - if any - of this diversity remains elusive. Standardized methods are lacking, but the most common metric for quantifying synchrony is the percentage of parasites in a particular developmental stage. We use a heuristic model to show that this metric is often unacceptably biased. Methodological challenges must be addressed to characterize diverse patterns of synchrony and their consequences for disease severity and spread.

Objective: To synthesise current evidence on electroencephalography-based functional connectivity in preterm infants and clarify how prematurity alters early brain-network maturation.
Methods: A PRISMA-guided search (PubMed and Web of Science, inception-Mar 2025) identified 24 studies that quantified resting-state functional connectivity or graph-theory metrics in infants born <37 weeks' gestation. Study quality was rated with a six-item electroencephalography-functional connectivity checklist (reference montage, epoch length/number, artefact rejection, volume-conduction control, multiple-comparison correction).

The extent to which phenological synchrony between trophic levels may be disrupted by environmental change has been a topic of increased focus in recent years. Phenological associations between deciduous trees, phytophagous insects, and their consumers (e.g.

The patient-therapist interpersonal dynamics is a cornerstone of psychotherapy, yet how it shapes clinical outcomes remains underexplored and difficult to quantify. This is also true in autism, where interpersonal interplay is recognized as an active element of intervention. Moreover, behavioral research is time-consuming and labor-intensive, limiting its translational applications.

Understanding how prey and predator species partition activity patterns across time and space is essential for elucidating behavioral adaptation and ecological coexistence. In this study, we examined the diel and seasonal activity rhythms of two sympatric rodent species- (Great gerbil) and (Midday gerbil)-and their primary predators, (Pallas's cat) and (Red fox), in a desert-steppe ecosystem on the northern slopes of the Qilian Mountains, China. Using over 8000 camera trap days and kernel density estimation, we quantified their activity intensity and spatiotemporal overlap.
