Lists, strings, and tuples have a positive index system:["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"] 0 1 2 3 4 5 6And a negative index system:["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"] -7 -6 -5 -4 -3 -2 -1In a list, the 2nd, 3rd, an...
negative index materialsmodulation instabilitynonlinear dispersionultrafast processesWe present an investigation of the critical frequency windows permitting modulation instability in negative index materials. The principal motivation for our analysis stems from the impact of the inevitable presence of the ...

However the examples miss a case with negative step value. With a negative step value, the start is implicitly set to -1. Which differs from positive step value cases, where if the start is skipped, the start index is implicitly set to 0. ...
If you are from python or ruby school, you shall be familar with negative array index, like a[-1] will return the last element, a[-2] will return the …
Here, we employ plasmon hybridization in semiconductor-metal-semiconductor core-multishell (CMS) nanowires as a unique approach to design low loss, isotropic and polarization dependant NIM in the visible range. Based on numerical simulations, we demonstrate an effective refractive index of 21 and a ...
A negative index accesses elements from the end of the list counting backwards. An example to show negative index in python >>>import array>>>a=[1,2,3]>>>print a[-3]1>>>print a[-2]2>>>print a[-1]3

“Unqualified microorganism, physical and chemical index”, “unapproved food additives or beyond the range”, and “uncompliant label” were the top 3 reasons for the risk warning. Among them, the microorganism, physical and chemical index was over 70%, which accounted for a large proportion ...
