Mechanistic Insights into the Surface Instabilities of TiNb2O7, a High‐Power Li‐Ion Anode
Advanced Materials Interfaces, EarlyView.TiNb2O7 is an attractive anode for Li‐ion batteries, particularly when safety is of the highest concern. However, despite operating at high potentials, electrolyte degradation is a major concern. It is demonstrated that throughout the entire charge‐discharge cycle a number of surface reactions occur which both produce gas and result in Ti dissolution ...

Understanding stock market instability via graph auto-encoders [PDF]
arXiv, 2022 Understanding stock market instability is a key question in financial management as practitioners seek to forecast breakdowns in asset co-movements which expose portfolios to rapid and devastating collapses in value. The structure of these co-movements can be described as a graph where companies are represented by nodes and edges capture correlations ...

Information aggregation, speculation, and arbitrage in a simple option market experiment
, 2001 The fact that all arbitrage opportunities are exploited is a fundamental assumption of option pricing theory. Empirical and experimental studies of investment decisions, however, found that arbitrage is not completely exploited by individuals.

Transaction costs and informational cascades in financial markets: theory and experimental evidence [PDF]
, 2006 We study the effect of transaction costs (e.g., a trading fee or a transaction tax, like the Tobin tax) on the aggregation of private information in financial markets.

Mathew Effect in Artificial Stock Market [PDF]
arXiv, 2004 In this article, we established a stock market model based on agents' investing mentality. The agents decide whether to purchase the shares at the probability, according to their anticipation of the market's behaviors. The expectation of the amount of shares they want to buy is directly proportional to the value of asset they hold.

High‐Detectivity GeSn Mid‐Infrared Photodetectors for Sensitive Infrared Spectroscopy
Advanced Photonics Research, EarlyView.This work introduces a complementary metal‐oxide‐semiconductor (CMOS)‐compatible, high‐detectivity mid‐infrared GeSn photodetector monolithically integrated on a silicon platform. Enabled by an innovative composition‐gradient GeSn buffer, the high‐quality, thick GeSn active layer delivers exceptional responsivity and detectivity across the mid‐infrared

Do investors trade too much? A laboratory experiment [PDF]
arXiv, 2015 We run experimental asset markets to investigate the emergence of excess trading and the occurrence of synchronised trading activity leading to crashes in the artificial markets. The market environment favours early investment in the risky asset and no posterior trading, i.e. a buy-and-hold strategy with a most probable return of over 600%.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
