The experiments reported were designed to examine how the interaction of task and organismic constraints influences the effectiveness of augmented information on the acquisition of a given force-time trace in a finger press isometric task. Experiment 1 showed that kinetic information feedback facilitated acquisition of the gaussian force-time task criterion but that the superimposition of the task criterion information on the augmented information feedback did not further improve performance. Experiment 2 revealed that the addition of task criterion information to the kinetic information feedback was beneficial to performance when the force-time curve was unfamiliar and asymmetrical in shape. Collectively, the findings suggest that the interaction of task and organismic constraints dictates the degree to which both kinetic information feedback and criterion information facilitate the acquisition of skill in isometric tasks.

ConspectusA key challenge in modern chemistry research is to mimic life-like functions using simple molecular networks and the integration of such networks into the first functional artificial cell. Central to this endeavor is the development of signaling elements that can regulate the cell function in time and space by producing entities of code with specific information to induce downstream activity. Such artificial signaling motifs can emerge in nonequilibrium systems, exhibiting complex dynamic behavior like bistability, multistability, oscillations, and chaos.

A vaccination programme against severe acute respiratory syndrome coronavirus 2 was initiated in Portugal in December 2020. In this study, we report the findings of a prospective cohort study implemented with the objective of monitoring antibody production in response to COVID-19 vaccination. The humoral immune response to vaccination was followed up using blood samples collected from 191 healthcare workers.

- The study focuses on how augmented feedback training can help reduce vertical ground reaction forces (vGRF) in female athletes landing from a height, ultimately aiming to prevent ACL tears.
- A total of 147 participants were tested under different conditions, leading to the identification of four response groups, with most athletes showing improvement from training.
- Findings highlight that both initial vGRF levels and the athletes' responses to training are crucial in predicting how well they can benefit from augmented feedback.

The research aims to investigate the mechanical response of footfalls at different velocities to understand the mechanism of heel injury and provide a scientific basis for the prevention and treatment of heel fractures. A three-dimensional solid model of foot drop was constructed using anatomical structures segmented from medical CT scans, including bone, cartilage, ligaments, plantar fascia, and soft tissues, and the impact velocities of the foot were set to be 2 m/s, 4 m/s, 6 m/s, 8 m/s, and 10 m/s. Explicit kinetic analysis methods were used to investigate the mechanical response of the foot landing with different speeds to explore the damage mechanism of heel bone at different impact velocities.
