Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Classification of the optimal rebalancing frequency for pairs trading using machine learning techniques

open access: yesBorsa Istanbul Review
Selection of the optimal rebalancing frequency (ORF) is crucial for the pair trading algorithm (PTA) that periodically rebalances the allocation of two assets. This study proposes a machine learning (ML) approach to predict ORF ranges.

Cointegration pairs trading strategy on derivatives. [PDF]

open access: yes, 2013
在現今的社會,協整技術已被廣泛應用於金融和計量經濟領域,特別用於構建股票市場的統計套利策略。在這一篇論文中,我們主要考察在衍生品市場中,基於協整技術的套利交易策略,這一策略的主要研究對象是隱含波動率。利用隱性波動率的線性組合的均值回歸的特性,通過配對兩隻帶有正利差(如theta) 的短期平價歐式跨式期權來獲利。同時,構建實際波動率的模型和預測未來實際波動率的模型將會用於補充這一交易策略的不足,隱性一實際條件和Gamma-Vega條件被引入來提高交易策略的效率 ...
