Cucumber (Cucumis sativus) seedlings grown in a horizontal position develop a specialized protuberance (or peg) on the lower side of the transition zone between the hypocotyl and the root. This occurs by suppressing peg formation on the upper side via a decrease in auxin resulting from a gravitational response. However, the gravity-stimulated mechanism of inducing asymmetric auxin distribution ...

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

Drosophila CNS precursors, neuroblasts, repeatedly divide to produce a large neuroblast and a smaller GMC. This division is asymmetric with regard to sibling cell size, mitotic potential and gene expression. Recent work has identified a number of molecules that show a polarized distribution during neuroblast mitosis: prospero RNA and Inscuteable, Miranda, Prospero, Staufen, and Numb proteins. T...

In the presence of a heavy-tail noise distribution, regression becomes much more difficult. Traditional robust regression methods assume that the noise distribution is symmetric, and they downweight the influence of so-called outliers. When the noise distribution is asymmetric, these methods yield biased regression estimators. Motivated by data-mining problems for the insurance industry, we pro...

The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality. The presence of asymmetric-tail dependence is not compatible with the assumption of a joint student -t distribution. A general test for ...

Bayesian analysis of a stochastic volatility model with a generalized hyperbolic (GH) skew Student’s t-error distribution is described where we first consider an asymmetric heavy-tailness as well as leverage effects. An efficient Markov chain Monte Carlo estimation method is described exploiting a normal variance-mean mixture representation of the error distribution with an inverse gamma distri...

Value-at-Risk (VaR) is a widely used statistical measure in financial risk management for quantifying the level of risk associated with a specific investment portfolio. It is well-known that historical return data exhibit non-normal features, such as heavy tails and skewness. Current analytical (parameteric) calculation of VaR typically assumes the distribution of the portfolio return to be a n...

Wireless sensor network promises ubiquitous data collection and processing for variety of commercial, healthcare and military applications. Practical realization of WSN applications is possible only after assuring network security. Cryptographic key distribution is an important phase in network security which establishes initial trust in the network. Security protocol implementation in WSN is l...

Phospholipase C was used as a probe for the distribution of phospholipids about the membrane of rough and smooth microsomal fractions from normal and phenobarbital-treated rat liver. All membranes exhibited an asymmetric distribution, with phosphatidylethanolamine and phosphatidylserine concentrated in the inner leaflet of the bilayer and phosphatidylcholine and sphingomyelin concentrated in th...
