On the harmonic mean representation of the implied volatility [PDF]
It is well know that, in the short maturity limit, the implied volatility approaches the integral harmonic mean of the local volatility with respect to log-strike, see [Berestycki et al., Asymptotics and calibration of local volatility models, Quantitative Finance, 2, 2002].

Using CAViaR models with implied volatility for value-at-risk estimation [PDF]
This paper proposes VaR estimation methods that are a synthesis of conditional autoregressive value at risk (CAViaR) time series models and implied volatility.

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

The implicit models of the option valuation
Of the alternative approaches to the Black-Scholes options valuation model, the implied models have had the largest development in last years. In this approach there are different alternatives: implied trees, deterministic volatility function models and ...

On the Curvature of the Bachelier Implied Volatility
Our aim in this paper is to analytically compute the at-the-money second derivative of the Bachelier implied volatility curve as a function of the strike price for correlated stochastic volatility models.

US Implied Volatility as A predictor of International Returns
This study provides evidence of the US implied volatility’s e ect on international equitymarkets’ returns. This evidence has two main implications: i) investors may find that foreign equityreturns adjusting to US implied volatility may not provide true ...

The predictive power of dollar-real call optionsimplied volatility
Previous empirical researches pointed out the relation between stress events in financial markets and implied volatility in option prices, indicating that large movements in asset prices would be preceded by significant increases in implied volatility ...

Dynamics of Connectedness in Clean Energy Stocks
This paper examines the dynamics of connectedness among the realized volatility indices of 16 clean energy stocks belonging to the SPGCE and the implied volatility indices of two important stock markets—the S&P 500 and the STOXX50—and two commodities ...

An Hilbert space approach for a class of arbitrage free implied volatilities models [PDF]
We present an Hilbert space formulation for a set of implied volatility models introduced in \cite{BraceGoldys01} in which the authors studied conditions for a family of European call options, varying the maturing time and the strike price $T$ an $K$, to
