The Role of Implied Volatility in Forecasting Future Realized Volatility and Jumps in Foreign Exchange, Stock, and Bond Markets [PDF]

open access: yes
We study the forecasting of future realized volatility in the foreign exchange, stock, and bond markets from variables in the information set, including implied volatility backed out from option prices.

Green Solvent Enabled Perovskite Ink for Ambient‐Air‐Processed Efficient Inkjet‐Printed Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
This study explores an eco‐friendly solvent with 1,3‐dimethyl‐2‐imidazolidinone for developing perovskite ink, enhancing grain size and formation of purer phase perovskite. The inkjet‐printed perovskite solar cells demonstrated a remarkable improvement in device power conversion efficiency from 14.6% to almost 17.8%, highlighting sustainable innovation

The Implied-Realized Volatility Relation with Jumps in Underlying Asset Prices [PDF]

open access: yes
Recent developments allow a nonparametric separation of the continuous sample path component and the jump component of realized volatility. The jump component has very different time series properties than the continuous component, and accounting for ...

Asymmetric Nanofiber Membranes for Simultaneous Moisture Adsorption and Rapid Catalytic Hydrolysis of Nerve Agent Simulants in Atmospheric Environments

open access: yesAdvanced Functional Materials, EarlyView.
Asymmetric nanofiber membranes are constructed for simultaneous moisture adsorption and catalytic hydrolysis of dimethyl 4‐nitrophenyl phosphate (DMNP) in a wide range of relative humidity. The membrane exhibits high moisture adsorption capacity and fast hygroscopic rate.

Comparative Study of Two Extensions of Heston Stochastic Volatility Model [PDF]

open access: yesarXiv, 2019
In the option valuation literature, the shortcomings of one factor stochastic volatility models have traditionally been addressed by adding jumps to the stock price process. An alternate approach in the context of option pricing and calibration of implied volatility is the addition of a few other factors to the volatility process.

The skew pattern of implied volatility in the DAX index options market [PDF]

open access: yes
The aim of this paper is twofold: to investigate how the information content of implied volatility varies according to moneyness and option type and to compare the latter option based forecasts with historical volatility in order to see if they subsume ...

Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

A Horserace of Volatility Models for Cryptocurrency: Evidence from Bitcoin Spot and Option Markets [PDF]

open access: yesarXiv, 2020
We test various volatility models using the Bitcoin spot price series. Our models include HIST, EMA ARCH, GARCH, and EGARCH, models. Both of our in-sample-fit and out-of-sample-forecast results suggest that GARCH and EGARCH models perform much better than other models.
