Dynamic emotion intensity estimation from physiological signals facilitating interpretation via appraisal theory.
PLoS One

Appraisal models, such as the Scherer's Component Process Model (CPM), represent an elegant framework for the interpretation of emotion processes, advocating for computational models that capture emotion dynamics. Today's emotion recognition research, however, typically classifies discrete qualities or categorised dimensions, neglecting the dynamic nature of emotional processes and thus limiting interpretability based on appraisal theory. In our research, we estimate emotion intensity from multiple physiological features associated to the CPM's neurophysiological component using dynamical models with the aim of bringing insights into the relationship between physiological dynamics and perceived emotion intensity.

Stone cells are one of the limiting factors affecting pear fruit quality and commodity value. The formation of stone cell is highly correlated with lignin deposition. However, the molecular mechanism of stone cell formation and regulation is still unclear.

Chronic migraine (CM) is the ultimate and most burdensome form of the transformation from episodic migraine (EM), called chronification. The mechanism behind migraine chronification is poorly known and difficult to explore as CM has the same spectrum of pathogenesis as EM and the EM-CM transition is bidirectional. Central sensitization (CS) is a key phenomenon in migraine: its mechanisms include disturbed neural plasticity, which is the ability of the nervous system to adapt to endo- and exogenous changes.

α-Synuclein (αS) is a 140 amino-acid neuronal protein highly enriched in presynaptic nerve terminals. Its progressive accumulation in Lewy bodies and neurites is the hallmark of Parkinson's disease (PD). A growing number of studies highlights a critical interplay between lipid metabolism and αS biology.

Increasing toxic metal pollution in the aquatic ecosystem since the industrial revolution produces serious environmental challenges and has raised critical questions of ecological and human health implications. As a typical aquatic plant, Nasturtium officinale (N. officinale) has drawn significant attention due to its remarkable accumulation of heavy metals and other harmful substances from polluted water.
