Abstract Background DNA double-strand break (DSB) induction and repair are important events for determining cell survival the outcome of cancer radiotherapy. The DNA-dependent protein kinase (DNA-PK) complex functions at apex DSBs repair, its assembly activity strictly regulated by post-translation modifications (PTMs)-associated interactions. However, PTMs catalytic subunit DNA-PKcs how they affect DNA-PKcs’s not fully understood. Methods Mass spectrometry analyses were performed to...
This paper develops a semiparametric Bayesian instrumental variable analysis method for estimating the causal effect of an endogenous when dealing with unobserved confounders and measurement errors partly interval-censored time-to-event data, where event times are observed exactly some subjects but left-censored, right-censored, or others. Our is based on two-stage Dirichlet process mixture (DPMIV) model which simultaneously models first-stage random error term exposure second-stage outcome...
Abstract Derivative warrants typically have higher prices than do otherwise identical options. Using data from the Hong Kong market during 2002–2007, we show that price difference reflects liquidity premium of derivative over Newly issued are much more liquid options with similar terms. As a result, long-term preferred by traders who trade frequently. In spite their prices, short-term returns on are, in fact, hypothetical The differences and measures decline as contracts get closer to maturity.
In this paper, we investigate the methodological issue of determining number state variables required for options pricing. After showing inadequacy principal component analysis approach, which is commonly used in literature, adopt a nonparametric regression technique with nonlinear components extracted from implied volatilities various moneyness and maturities as proxies transformed variables. The methodology applied to prices S&P 500 index period 1996–2005. We find that, addition value...
Abstract The activation of DNA‐dependent kinase (DNA‐PKcs) upon DNA damage contains a cascade reactions, covering acetylation by TIP60, binding with Ku70/80, and autophosphorylation. However, how cells regulate TIP60‐mediated DNA‐PKcs the following remains obscure. This present study reported that TIP60 is hyper‐SUMOylated in normal conditions, but irradiation‐induced damage, small ubiquitin‐like modifier (SUMO)‐specific protease 3 (SENP3)‐mediated deSUMOylation promoted its interaction to...
Bicarbonate enhanced the degradation of organic pollutants over oxygen doped graphitic carbon nitride nanosheets in presence hydrogen peroxide. It occurred both on surface catalyst and reaction solution.
Purpose This paper aims to study whether noisy public information that investors receive about the expected aggregate dividend growth rate can help better understand large average equity premium and stock return volatility in US financial market. Design/methodology/approach considers a dynamic asset pricing model with representative agent, who cannot observe of dividends must learn its value by using information. In addition, this presents simple for calibration. Findings With coefficient...
Abstract This paper documents a significant positive impact of the liquidity underlying stocks on derivative securities basis sample options and warrants traded in Hong Kong. The study relies an exogenous change stocks, namely, tick size reduction implemented by Kong Stock Exchange (HKEx), which significantly reduces bid-ask spreads stocks. are also reduced, especially those less liquid with greater inventory risk. results consistent hedging theory Cho Engle (1999) shed light sources securities.
When the true asset pricing model cannot be identified, idiosyncratic volatility obtained from a misspecified contains information of hedge portfolio in Merton's (1973) ICAPM.Empirically, I find that 1815 to 2018, more than two centuries, neither equalweighted (EWIV) nor value-weighted (VWIV) can forecast stock market returns.However, EWIV and VWIV when applied together are strong predictors returns over short-and long-term horizons.The explanatory power is economically significant with an...
We investigate how a firm’s mandatory and voluntary disclosures affect market expectation of its suppliers’ future stock price volatility. use the change forward implied volatility as quantitative measure new information. Our main findings include following. First, announcing short-term volatility, on average, drops substantially after earnings announcements but increases unbundled management guidance. In contrast, distribution centers at zero both types disclosures. Second, there exists...
We find that the FOMC-announcement-day return premium earned by a firm is positively related to increase in its ex ante, option-implied skewness prior announcement. This finding consistent with: (1) existence of an announcement-day Fed put partially anticipated financial market; (2) pre-announcement firm’s being proxy for exposure (FPE); and (3) FPE commanding positive price risk. High (low) firms are those whose preannouncement largest (smallest). high indeed experience larger (smaller)...
Based on the value of investment theory, using annual compound growth returns rate as major indicator after adjusting price according to ex-rights and dividends, this article conducts an analysis Long-term during 1991 2008 Shenzhen Stock Market. Study found that long-term industry are quite different, existing large-cap effect small firm effect, also having a clearly volatility characteristic compared Treasury yields.
