Abstract

fetched live from OpenAlex

Background The purpose of this study was to assess the effectiveness of an energy drink vs. a caffeine-matched control on mental and physical performance.Methods Using a randomized, double-blind design (n = 62), subjects were assigned to an energy drink (Ghost®) or a caffeine-matched control (200 mg caffeine). The following assessments were conducted before and approximately 45 minutes after consuming an energy drink or caffeine-matched control: psychomotor vigilance test (PVT), CNS Tap Test, handgrip strength, and POMS.Results Table 1 shows the subject demographics. There were no significant differences between the treatment and control for any of the assessments. Both groups improved in the total mood disturbance score; in addition, treatment improved in the CNS Tap Test. However, there were no between-group differences for any of the other assessments.Conclusions Consuming the energy drink or caffeine-matched control resulted in an improvement in the total mood disturbance. In addition, consuming the energy drink significantly improved the CNS Tap Test score. However, there were no between-group differences for any of the measures. Thus, it is ostensible that any effect of an energy drink is likely due primarily to caffeine itself.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
