terminology – Is the term “service city” correct for the main city served by an airport placed outside of that city?

Some airports of big cities are, in fact, technically speaking in a “very near municipality” which is not the main city itself.

For example the airport BCN serving “Barcelona” is, in fact, placed in the city “El Prat del Llobregat” which is 15 Km south from Barcelona.

Or for example the airport CDG serving “Paris” is, in fact, at the town “Roissy” 25 Km northeast from Paris.

I “think” (but can’t confirm) I have heard the term “Service City” to refer to the “main city” the airport is conceptually associated to. For example to say “CDG’s service city is Paris”.

I’m trying to confirm this terminology with no luck.

Can anyone confirm, if this term is correct and provide any public source defining the term? If the term is not correct, what would be the correct one?

calculus – Justification for the absolute value for a Jacobian-like term in a differential expression

Assuming we have that
$$
N = iiint f(r,theta, phi) r^2 sin theta mathrm{d}r mathrm{d} theta mathrm{d} phi
$$

I wish to write an expression using a change of variables:
$$
frac{dN}{dt} = iint f(r,theta, phi) r^2 sin theta frac{mathrm{d}r}{dt} mathrm{d} theta mathrm{d} phi
$$

However, based on the solutions to this expression, it seems that this expression is not quite correct and it requires an absolute value:
$$
frac{dN}{dt} = iint f(r,theta, phi) r^2 sin theta left| frac{mathrm{d}r}{dt} right| mathrm{d} theta mathrm{d} phi
$$

which is similar to a Jacobian should the limits of integration not be flipped as per this stackexchange answer. However, given that there are no limits of integration in the above expression – that is, neither r not t are being integrated over, I am not sure of the precise justification for the absolute value or if it is legitimate.

cv.complex variables – Cauchy’s Integral with quadratic exponential term

As I was studying the Cauchy’s integral formula, I tried to do the integral:

begin{equation}
I(x) = int_{-infty}^{infty} frac{1}{x – a} e^{(i A x^2 + i B x)} dx
end{equation}

with $A>0, B>0$ and $a > 0$.

Consider an integral on a complex plan:
begin{equation}
J(z) = int_{C + C_R} frac{1}{z – a} e^{(i A z^2 + i B z)} dz
end{equation}

where $C$ is along the real axis $-infty rightarrow +infty$ and $C_R$ is the upper half circle $z = Re^{itheta}$ with $R rightarrow infty$ and $theta in (0, 2pi)$.

Naively, I would expect $C_R$ part of the integral gives zero and $C$ part of the integral gives $I(x)$, then the $I(x)$ can be derived by Cauchy’s integral formula.

However, as I tried to check the $C_R$ part of the integral, I found that:
begin{array}
$I_R(z = Re^{itheta}) &=& int_0^{pi} dtheta frac{iRe^{itheta}}{Re^{itheta} – a} exp(iAR^2e^{2itheta}+iBRe^{itheta})
end{array}

begin{array}
$|I_R| &leq & int_0^{pi} dtheta |frac{iRe^{itheta}}{Re^{itheta} – a}| |exp(iAR^2e^{2itheta}+iBRe^{itheta})|
end{array}

where the first term

begin{equation}
|frac{iRe^{itheta}}{Re^{itheta} – a}| leq frac{R}{R-a} rightarrow 1 as R rightarrow infty
end{equation}

and the second term
begin{equation}
|exp(iAR^2e^{2itheta}+iBRe^{itheta})| leq e^{-AR^2sin(2theta) – BRsin(theta)}
end{equation}

will not approach to zero because of $e^{-AR^2sin(2theta)}$.

Is there anything wrong in my approach? And is there any other way I can perform this integral I(x)?

Thanks a million for advises!

migration – Migrate content with referenced taxonomy being migrated by term name

Is it possible to migrate content with term reference fields, but instead of referencing terms by their tid they are referenced by their term name?

instead of this:

field_tags:
  plugin: sub_process
  source: field_tags
  process:
    target_id: tid

Do something like this:

field_tags:
  plugin: sub_process
  source: field_tags
  process:
    target_id: [term name]

malware – Why is the term “nation state” used to refer to a government-sponsored effort in infosec, and is it accurate?

I work in infosec and as such, have read many whitepapers and been to many conference talks. I hear all the time, especially in conversation and literature about malware, the term “nation state” used to refer to a government entity or government-sponsored activity. The term “state actor” is also used.

My question is, why? According to Wikipedia:

A nation state is a state in which a great majority shares the same culture and is conscious of it. The nation state is an ideal in which cultural boundaries match up with political boundaries.1 According to one definition, “a nation state is a sovereign state of which most of its subjects are united also by factors which defined a nation such as language or common descent.” It is a more precise concept than “country”, since a country does not need to have a predominant ethnic group.

According to Merriam-Webster, the definition is:

a form of political organization under which a relatively homogeneous people inhabits a sovereign state

Is there some inherent need for the government sponsor to be primarily of one ethnic background in infosec literature? I just don’t understand why this term in particular is so frequently used, when there are many forms of states, such as a federated state, multinational state, or even more general terms such as “government” or “country,” all of whom would likely be capable of and do participate in infosec activities.

wp query – Capture search term, input into 2 searches and output data on 1 page

Apologies if this may seem trivial but, although i’ve been working with WordPress for a few years now, i only recently started using slightly more complex code implementations.

What i am trying to do is the following:

  1. Present the user with a single textbox (Search) to input a search term
  2. Capture that search term and input into the standard wordpress search as well as a custom Bing search
  3. Output the data from both searches on a single page

At the moment i am using 2 separate search boxes and results pages for both searches but i would ideally like to amalgamate them so that they are transparent to the user, if this is even possible without extremely heavy customisation.

I’ve Googled this over and over and was able to find some articles on creating custom WP search forms or search results pages but i none with regards to implementing anything similar to what i described above so any help would be greatly appreciated.

Thanks so much in advance.
