Observation of Physiological Changes During Transcendental Meditation

Techniques of yoga have been associated with alterations in physiology, but until recently there has been only haphazard and uncontrolled research . Since 1970, information has been gathered which suggests that the practice of Transcendental Meditation (TM), a derivative of yoga, significantly affects changes in several physiological areas. This study observed changes in breath rate and peripheral circulation before, during, and after the practice of TM. Results showed a significant decrease in breath rate and changes in circulation patterns in the hand and forehead of subjects

Income and Price Effects in an Alternate Exposition of the Theory of Clubs

As Buchanan noted in his original paper, the economic theory of clubs allows us to move one step forward in closing the awesome Samuelson gap between the purely private and the purely public good. [3, p.l]. Although the theory applies only to goods from which nonpayers can be excluded, the step forward his analysis permits is large. An alternate exposition of the theory is presented in Richard and Peggy Musgrave\u27s textbook [6, pp. 615-622]; and a graphic conden sation of their exposition was developed by Allen, Amacher, and Tollison [1, pp. 386-91]

The Science Performance of JWST as Characterized in Commissioning

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-launch expectations. Commissioning has made clear that JWST is fully capable of achieving the discoveries for which it was built. Moreover, almost across the board, the science performance of JWST is better than expected; in most cases, JWST will go deeper faster than expected. The telescope and instrument suite have demonstrated the sensitivity, stability, image quality, and spectral range that are necessary to transform our understanding of the cosmos through observations spanning from near-earth asteroids to the most distant galaxies.Comment: 5th version as accepted to PASP; 31 pages, 18 figures; https://iopscience.iop.org/article/10.1088/1538-3873/acb29

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

A Milestoning Study of the Kinetics of an Allosteric Transition: Atomically Detailed Simulations of Deoxy Scapharca Hemoglobin

Atomically detailed simulations are used to compute the kinetics of the R-to-T transition in deoxy Scapharca hemoglobin. A computational approach called milestoning is utilized that combines 1), an efficient reaction path algorithm; and 2), a “fragment and glue” approach for classical trajectories. Milestoning computes the R-to-T transition kinetics on the microsecond timescale based on atomically detailed trajectories that rarely exceed a nanosecond. Eleven reference hypersurfaces (milestones) are constructed along the reaction coordinate, which is computed with a global path optimization algorithm. Two-hundred classical trajectories are calculated for each of the milestones to collect local distributions of first passage times. These local distributions are used in a non-Markovian theory to compute the overall timescale. Exponential enrichment of reactive trajectories, an important component of the milestoning approach, makes these calculations possible. The overall timescale of the reaction is estimated as 10 ± 9 μs, in accord with available experimental data. The barrier is not sharp and is spread over four milestones. Even after the most significant structural changes are completed (phenylalanine F4 ring flips), highly collective and activated motions continue. The calculations suggest an additional late free energy barrier
