The poor agreement for some tumours can be noted, which can partly be explained by considerable geometric differences in the identification of the tumour by the two operators, for example in tumour 2, causing the DSC to be low for the threshold-based methods.

The idea presented in [10] is interesting, however it cannot be applied for a large class of operators, as, for example, in the case of an implicit contraction.
This more general class, which properly includes the classes of quasi-nonexpansive operators, directed operators, and demicontractive operators, is more desirable for example in fixed point methods in image recovery where in many cases, it is possible to map the set of images possessing a certain property to the fixed point set of a nonlinear quasi-nonexpansive operator.
Various problems for functional differential equations with causal operators were considered, for example, in papers [1 10], in particular, the existence of solutions by using the monotone iterative method; see, for example, [2, 6 8].
Sporting five fully movable fingers, the Handroid looks a lot like the hand Arnold Schwarzenegger uses in Terminator 2. Operators can control each finger remotely (the Handroid can mimic the operator's movements), for example in environments where it's too dangerous to use human hands.
Properties of this operator were studied, for example, in [26, 27].
However, KeystoneML provides both a richer set of built-in operators – for example, image featurizers and large-scale linear solvers – and modifies the spark.ml interface to provide type-safety and ensure further robustness.
The asymptotics of eigenvalues and trace formulas for operators generated by differential expressions with operator coefficients are studied, for example, in [3 7].
The rule limits drone operators, for example, from flying their UAVs in the dark of night, beyond the visual line of sight of a pilot, or over densely populated areas¬ unless they have attained an FAA exemption to do so.
They are needed either because direct operator control is impossible (for example, in space probes so distant that radio signals take minutes or hours to reach them) or because humans lack the skill or the desire to oversee all the details (in such down-to-earth systems as office machines, water treatment plants, and internal combustion engines).
Note also that, for (psi_{2}equiv0), we obtain the weighted differentiation composition operator, which was studied, for example, in [17 19, 28, 30].

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
