Optimizing cellulose fraction for enhanced utility: Comparative pre-treatment of Agave tequilana Weber var. blue bagasse fiber for sustainable applications

Heliyon
In recent decades, natural fibers have emerged as an alternative to synthetic fibers due to their renewable nature, lower environmental impact, and comparable strength properties. Agave bagasse, a byproduct of agave juice extraction in Mexico, stands out

Formalin-induced pain prolongs sub- to supra-second time estimation in rats [PDF]

PeerJ, 2021
Background Temporal estimation can be influenced by pain, which is a complex psychological and physiological phenomenon. However, the time range in which perception is most sensitive to pain remains unclear.

Variation in the “coefficient of variation”: Rethinking the violation of the scalar property in time-duration judgments

Acta Psychologica, 2021
The coefficient of variation (CV), also known as relative standard deviation, has been used to measure the constancy of the Weber fraction, a key signature of efficient neural coding in time perception.

Revisiting and Implementing the Weber and Ventilatory Functional Classifications in Heart Failure by Cardiopulmonary Imaging Phenotyping

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background In heart failure, the exercise gas exchange Weber (A to D) and ventilatory classifications (VC‐1 to VC‐4) historically define disease severity and prognosis.

Numerosity Comparison in Three Dimensions in the Case of Low Numerical Values

Brain Sciences, 2023
This study investigated the perception of numbers in humans in 3D stimuli. Recent research has shown that number processing relies on “number sense” for small values, in line with Weber’s law.

Vibrotactile mapping of the upper extremity: Absolute perceived intensity is location-dependent; perception of relative changes is not

Frontiers in Neuroscience, 2022
Vibrotactile sensation is an essential part of the sense of touch. In this study, the localized vibrotactile sensation of the arm-shoulder region was quantified in 10 able-bodied subjects.

Number comparison under the Ebbinghaus illusion

Frontiers in Psychology, 2022
A series of studies show interest in how visual attributes affect the estimate of object numbers in a scene. In comparison tasks, it is suggested that larger patches are perceived as more numerous.
