A Theory of Market Efficiency [PDF]

open access: yesarXiv, 2017
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.

An Iterative Mechanism for Coupling Electricity Markets [PDF]

open access: yesarXiv, 2020
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.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

open access: yesAdvanced Functional Materials, Volume 35, Issue 23, June 5, 2025.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

Narrowband Detection via Charge Collection Narrowing Organic Photodetector Enabled by Low Bandgap Random Terpolymer for Biometric Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A novel low‐bandgap random terpolymer is designed for narrow band detection in charge collection narrowing (CCN) based organic photodetectors. With a relative thin active layer (<1 µm), the CCN‐based devices achieved a narrowband response of 68 nm full‐width‐at‐half‐maximum at 916 nm, together with Responsivity values of 0.13 A W−1 and dark current of ...
