Gamma is the first derivative of delta and is used when trying to gauge the price movement of an option, relative to the amount it isin the moneyorout of the money. It describes how the delta will change as the
John is a trader with a portfolio of options that has a neutral gamma position. If the price of the underlying asset increases, the gamma of the options also increases. To maintain a neutral gamma exposure, John would sell some options to offset the increased gamma. This allows the trader ...
Gamma is used to determine how stable an option’s delta is: Higher gamma values indicate that delta could change dramatically in response to even small movements in the underlying asset’s price. Gamma is higher for options that are at the money and lower for options that are in and out ...
ClickModels is a small set of Python scripts for the user click models initially developed at Yandex. A Click Model is a probabilistic graphical model used to predict search engine click data from past observations. This project is aimed to deal with cli
Atherosclerosis is the root cause of many cardiovascular diseases. Extensive research in preclinical models and emerging evidence in humans have established the crucial roles of the innate and adaptive immune systems in driving atherosclerosis-associated chronic inflammation in arterial blood vessels. New te...
The light-sensitive emulsion used to create holograms makes a record of the interference between the light waves in the reference and object beams. When two wave peaks meet, they amplify each other. This is constructive interference. When a peak meets a trough, they cancel one another out. Th...

What are RAW files used for? The highest-quality images often start out as RAW files.DSLR camerascapture and hold image data in RAW files, which are typically large and highly detailed because there is no compression. Image generation software can sometimes create RAW files too, but this is ...
Peak white luminance (10% win): This is the maximum brightness in nits using the brightest (but not necessarily the most accurate) SDR and HDR picture mode. Good is 500 or higher (1,000 for HDR), Average is 300 or higher (700 for HDR) and Poor is anything dimmer. Avg. gamma (10...
The speed of light is so immutable that, according to the U.S.National Institute of Standards and Technology, it is used to define international standard measurements like the meter (and by extension, the mile, the foot and the inch). Through some crafty equations, it also helps define the...
