A Theory of Market Efficiency [PDF]
We introduce a mathematical theory called market connectivity that gives concrete ways to both measure the efficiency of markets and find inefficiencies in large markets. The theory leads to new methods for testing the famous efficient markets hypothesis that do not suffer from the joint-hypothesis problem that has plagued past work.

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Comparing Prediction Market Structures, With an Application to Market Making [PDF]
Ensuring sufficient liquidity is one of the key challenges for designers of prediction markets. Various market making algorithms have been proposed in the literature and deployed in practice, but there has been little effort to evaluate their benefits and disadvantages in a systematic manner.

A highly‐entangled polyacrylamide (HE‐PAM) hydrogel is designed as an aqueous electrolyte for the fast charging/discharging properties in Zn/MnO2 batteries. Such hydrogel electrolyte possessed excellent mechanical characters, stable cycling capability, and superb rate performance under high current densities. These characters can also be applied in the

An Iterative Mechanism for Coupling Electricity Markets [PDF]
The coordinated operation of interconnected but locally controlled electricity markets is generally referred to as a "coupling". In this paper we propose a new mechanism design for efficient coupling of independent electricity markets. The mechanism operates after each individual market has settled (e.g.
