Double Exponential Instability of Triangular Arbitrage Systems

, 2012
If financial markets displayed the informational efficiency postulated in the efficient markets hypothesis (EMH), arbitrage operations would be self-extinguishing. The present paper considers arbitrage sequences in foreign exchange (FX) markets, in which

Machine Learning for Green Solvents: Assessment, Selection and Substitution

Advanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,

THE EFFICIENT MARKETS HYPOTHESIS

, 2012
Although something of a chameleon (Findlay and Williams, 2008), the efficient markets hypothesis (EMH) reduces to a claim that ‘you can’t beat the market’. In its weak form, it holds that past financial data are no guide to the future. In its stronger forms, it maintains that financial asset prices represent ‘fundamental value’, except to the extent ...

Efficiency in Brazilian Agricultural Futures Markets

Economia Aplicada, 2015
We aim to test the random walk hypothesis to agricultural future contracts traded at the Brazilian Board of Trade (BM&FBOVESPA). Refute this hypothesis means possible predictability, therefore these markets are not weakly efficient.

Testing Semi-strong Form Efficiency of Stock Market [PDF]

The efficient market hypothesis suggests that stock markets are “informationally efficient”. That is, any new information relevant to the market is spontaneously reflected in the stock prices.

CO Spillover Is Not a Promoter for C─C Bond Formation in CO2 Electroreduction on Cu‐Ag Bimetallic Catalysts

Advanced Science, EarlyView.
CO spillover via the Cu‐Ag interface does not promote C‐C coupling. ABSTRACT Cu‐based bimetallic catalysts have been shown to improve the multi‐carbon (C2+) selectivity in CO2 electroreduction, with the assumption that CO spillover from the CO‐selective catalysts to adjacent Cu domains via their bimetallic interface promotes C–C coupling. Here, through

Enhanced Bandgap Flexibility in Perovskite‐Silicon Tandem Solar Cells via Three‐Terminal Architecture

Advanced Science, EarlyView.
Three‐terminal (3T) perovskite/silicon tandem solar cells overcome the current‐matching constraints of 2T designs. Using an IBC POLO silicon bottom cell, we demonstrate a 30.1% PCE, with performance largely decoupled from perovskite bandgap and enhanced resilience under realistic, time‐dependent solar spectra.

Systematic Metabolic Engineering and Model‐Guided Optimization for High‐Level Production of L‐Theanine from Xylose in Escherichia coli

Advanced Science, EarlyView.
This study is pioneering in constructing the shortest known synthetic pathway for L‐theanine production from xylose within E coli. Through comprehensive metabolic engineering strategies, our engineered strain achieved the highest reported L‐theanine titer from xylose, with a titer of 95.42 g/L, and a yield of 0.55 g/g.

Performance Anomalies and Determinants of Equity Funds: Evidence from Türkiye

Ekonomi, Politika & Finans Araştırmaları Dergisi
This study aims to contribute to the literature by examining whether the returns of equity funds represent a new source of anomaly within the framework of the Efficient Markets Hypothesis.
