Sphinx (gene)

In molecular biology, Sphinx (spx) is a long non-coding RNA found in Drosophila. It is expressed in the brain, within the antennal lobe and inner antennocerebral tract. It is involved in the regulation of male courtship behaviour, this may be via olfactory neuron mediated regulation. Sphinx may act as a negative regulator of target genes. It is a chimeric gene, originating from a retroposed sequence of the ATP synthase chain F gene from chromosome 2 to chromosome 4. Nearby sequences were recruited to form an intron and an exon of this chimeric gene.

Sabre I

The first Sabre was a former knife thrower named Paul Richarde until he was selected by Modred to oppose Black Knight. Paul Richarde was given an armor, an animated gargoyle. and Mordred's Ebony Dagger (the weapon with which Mordred had killed the first Black Knight). He was defeated by Black Knight after his horse Aragorn kicked the dagger from Le Sabre's hand.

Sabre II

The second Sabre is a mutant super villain. His first appearance was in X-Men #106. Young and reckless, Sabre was chosen by Mystique to join her new Brotherhood of Mutants, though never actually participated in any missions. He had the mutant ability of super speed, and took the name of the deceased Super Sabre. It is unknown if he continues to serve Mystique behind the scenes, or if he even retains his powers after Decimation. Hyper-accelerated metabolism augments his natural speed, reflexes, coordination, endurance, and the healing properties of his body.

Sphinx (Romania)

The Sphinx (Romanian: Sfinxul) is a natural rock formation in the Bucegi Natural Park which is in the Bucegi Mountains of Romania. It is located at an altitude of 2,216 metres (7,270 ft), a 10-minute walk from the Babele.

The first photo of the Great Bucegi Sphinx was probably taken in about the year 1900. This photograph was taken from a front position, not from a lateral one, as it usually appears in pictures nowadays. It only acquired its nickname, referring to the Great Sphinx of Giza, in the year 1936. The image of the sphinx appeared when the rock, having an 8 m height and a 12 m width, was watched from a certain angle. The megalith has its clearest outline on 21 November, at the time the sun goes down.

In Romanian film

The Sphinx features in the 1967 film The Dacians, in which it is a place of sacrifice to the god Zalmoxis. It also plays a significant role in the 1980 film Burebista, in which it is equated with the eponymous ancient Dacian king and the eternity of Romanian identity.

Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Gamma (store)

Gamma is a Dutch Hardware store-chain. It started in May 11, 1978 in Breda. The headquarters of the franchise-organisation Intergamma is located in Leusden and as of 2011 it has 245 stores, of which 164 are located in the Netherlands and 81 in Belgium. Intergamma also owns the Hardware store-chain Karwei.

History

In 2008 Gamma had a revenue of 606 million euro.

Gamma commercials have been broadcast in the Netherlands on radio and television since 1994, and have made the actors John Buijsman and Martin van Waardenberg well known in the Netherlands. In Flanders Luk Wyns is the face of the company.
