Physiological Synchrony Predict Task Performance and Negative Emotional State during a Three-Member Collaborative Task.

Evaluation of team performance in naturalistic contexts has gained popularity during the last two decades. Among other human factors, physiological synchrony has been adopted to investigate team performance and emotional state when engaged in collaborative team tasks. A variety of methods have been reported to quantify physiological synchrony with a varying degree of correlation with the collaborative team task performance and emotional state, reflected in the inconclusive nature of findings.

Altering Fish Behavior by Sensing Swarm Patterns of Fish in an Artificial Aquatic Environment Using an Interactive Robotic Fish.

Numerous studies have been conducted to prove the calming and stress-reducing effects on humans of visiting aquatic environments. As a result, many institutions have utilized fish to provide entertainment and treat patients. The most common issue in this approach is controlling the movement of fish to facilitate human interaction.

Cationic gold(I)-catalyzed glycosylation with glycosyl -1,1-dimethylpropargyl carbamate donors.

A mild and efficient cationic gold(I)-catalyzed -glycosylation methodology involving the use of bench-stable glycosyl -1,1-dimethylpropargyl carbamate donors has been developed. In the presence of 1-2 mol% [tris(2,4-di--butylphenyl)phosphite]gold(I) chloride and 5 mol% silver triflate, both "armed" and "disarmed" glycosyl -1,1-dimethylpropargyl carbamate donors react with various sugar acceptors at room temperature to afford the corresponding glycosides in good to excellent yields. These glycosyl -1,1-dimethylpropargyl carbamates are found to be orthogonal to regular phenyl thioglycoside donors.

Stereoselective β-Mannosylation via Anomeric -Alkylation with L-Sugar-Derived Electrophiles.

A total synthesis of the trisaccharide repeat unit of serogroup E1 -antigen is reported. This synthesis features a key β-mannosylation reaction via cesium carbonate-mediated anomeric -alkylation of a partially protected D-mannose with an L-fucose-derived electrophile for the first time.

Evaluating Operator Training Performance Using Recurrence Quantification Analysis of Autocorrelation Transformed Eye Gaze Data.

Objective: This research aimed to investigate the relationship between gaze behaviour dynamics and operator performance.

Background: Individuals differ in their approach when learning a new task often resulting in performance disparity. During training some individuals learn the structure and dynamics of the task and develop a systematic approach, whereas others may achieve the same result albeit with increased perceived workload, or indeed some may fail to achieve superior performance levels.
