An experimental comparison of contributions in collective prevention games and public goods games

Economic Inquiry, Volume 62, Issue 4, Page 1598-1617, October 2024.
Abstract In many collective action problems individuals' contributions increase the probability of a collectively favorable event rather than affect the quantity of public goods provided. Such problems, that we refer to as collective prevention games, remain largely unexplored in the literature.

An optimized AC side startup strategy of E‐STATCOM for ITER pulsed power electrical network

IET Generation, Transmission &Distribution, Volume 18, Issue 16, Page 2719-2731, August 2024.
In this article, an energy consumption optimization startup strategy of E‐STATCOM system using supercapacitor energy storage based MMC is proposed. This startup strategy avoids the use of current limiting resistors in supercapacitor energy storage circuits and reduces additional energy loss.

Solar System Processes Underlying Planetary Formation, Geodynamics, and the Georeactor

, 2006
Only three processes, operant during the formation of the Solar System, are responsible for the diversity of matter in the Solar System and are directly responsible for planetary internal-structures, including planetocentric nuclear fission reactors, and

Monitoring of Allowable Bending Stress Overload in Glass‐Fiber‐Reinforced Polymer Composites Using Magnetostrictive Fe–Co Fibers

Advanced Engineering Materials, Volume 26, Issue 4, February 2024.
This article discusses the magnetostrictive behavior of Fe–Co fibers in glass‐fiber‐reinforced‐polymer (Fe–Co fiber/GFRP) composites. The magnetic flux density outside the Fe–Co fiber/GFRP composite specimens is monitored during the four‐point bending tests.

Sampling the Materials Space for Conventional Superconducting Compounds

Advanced Materials, Volume 36, Issue 1, January 4, 2024.
A large‐scale, machine‐learning‐accelerated study of conventional superconducting materials is presented, wherein the transition temperatures of approximately 200 000 metallic compounds are evaluated, all of which are close to the convex hull of thermodynamic stability to maximize the probability of synthesizability.

A Legal Regime for the Mining of Helium-3 on the Moon: U.S. Policy Options [PDF]

, 2009
Absent an agreed international legal framework, attempts by the United States or any other nation or private entity to acquire and bring to Earth significant quantities of He-3 could give rise to controversy and conflict. Consequently, it seems timely to

A MHD reverse flow in 90 degree bend

, 2018
A two-dimensional flow in a 90 degree bent channel is considered. A magnetic field is uniform and parallel to inlet branch of the channel. A spectral/hp element method was used for liquid motion calculations. Three types of steady flows were detected. It

Nuclear astrophysicists at war

Natural Sciences, Volume 4, Issue 1, January 2024.
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...
