Australia and New Zealand have the highest melanoma rates in the world with Queensland incidence rate of 71 cases per 100,000 people (for the years 2009-2013), vastly exceeding rates in all other jurisdictions nationally and internationally.

Would be hard to know without further muscle testing, however my thought are that it's semimembranosus (green arrow) with semitendinosus over the top (red arrow, more defined part at the bottom of the muscle).

Scene brightness in Ev?

We often see, especially in camera specifications, a factor that seems
to be scene luminance (brightness) described in terms of an Ev
number. Such a factor might be, for example, the lowest scene
luminance for which the exposure metering system of the camera is
able to function reliably.

This usage is unfortunate and technically inappropriate, as Ev is a
measure of exposure, not luminance. There is a perfectly good APEX
quantity for luminance: Bv. I suspect the motive for the practice is
that many photographic enthusiasts have heard of Ev but not Bv.

Of course, if we know the Ev that a camera’s metering system
recommends for a scene, we can in fact equate that to scene
luminance if we also know the ISO sensitivity (Sv) in effect.

It turns out that, when a manufacturer states some critical scene
luminance in terms of “Ev”, and nothing to the contrary is stated, it is
most often based on the assumption that the ISO sensitivity is
ISO 100 (Sv 5). (Canon, for example, so states explicitly.) In other
words, the luminance being described is that which, if the ISO
sensitivity of the camera were ISO 100, would lead to the camera
arranging for an exposure of the stated Ev.

The relationship between this irregular description of scene luminance
in “Ev” and the description of that luminance in the proper value, BV,
is as follows:

Bv=Ev’–5

where Ev’ is the so-called “Ev” used to describe the luminance.

I discourage this usage.

1. Quantum Efficiency (QE) is how efficiently photons are being converted to photo-electrons. To increase this you need to either increase the Fill-factor, by adding or improving the microlenses above every sensel or use a more transmittive Colour Filter Array or remove the CFA completely and shoot monochrome. By using high voltage it is possible to use photon-multiplication and avalanche-mode techniques to increase the number of photo-electrons released by a photon, but such methods are too complex and costly for consumer DSLRs and are usually reserved for specialised surveillance and military usage.


2. Conversion Gain (CG) is how large an output voltage is produced per photo-electron. Since the number of photons captured is still the same, the shot noise SNR is still the same. But a high CG helps to overwhelm the read noise (RN) being contributed by the output Source Follower (SF) transistor associated with each sensel. Sensor design usually involves trade-offs. High CG (HCG) improves the noise performance at low Light levels (LL). But HCG means that less photons can be captured before either the FWC of the sensel is reached or the ADC runs out of digits. When dealing with LL, there aren't that many photons so HCG is desirable. But in good light, noise is not a problem, but a large FWC leads to a better Dynamic Range (DR), hence the desirability of LCG. In most sensors, the chosen CG was therefore a compromise.

In most semiconductors, the effective mass of a hole is much larger than that of an electron. This results in lower mobility for holes under the influence of an electric field and this may slow down the speed of the electronic device made of that semiconductor. This is one major reason for adopting electrons as the primary charge carriers, whenever possible in semiconductor devices, rather than holes. Also, why NMOS logic is faster than PMOS logic.
