Q: Does Iran make its own engines for its helicopters?

against very long user namesIranian companies have 'cloned' some Western helicopter models but also made their own, more recently. Do they have the domestic capability to make engines for them though, or are these imported, if so from where? (E.g. Shaded drone engines were imported from Europe and then from China.) N.B. In ...

Q: Normalisation of models of elliptic curves in finite extensions and reducedness of fibres

David HubbardLet $K$ be a complete local field of characteristic 0 with residue field $k$ of characteristic $p>0$ and ring of integers $R=\mathcal{O}_{K}$. Suppose we have an isogeny of elliptic curves: $$f:F\rightarrow E$$ over $K$ and let $\mathcal{C}$ be the minimal proper regular model of $E$ over $R$. Su...

Q: Paper rejected twice, once because two true statements imply each other, once because two false statements imply each other?

templatetypedefI remember a while back finding an anecdote about a paper in set theory from the early 20th century establishing an equivalence between two concepts (I think, but I’m not sure, that it was the axiom of choice and the well-ordering principle). The story goes that the paper was rejected from one jo...

Q: Are artificial lights at night bad for Venus flytraps?

FluxI am growing a Venus flytrap (Dionaea muscipula) on a porch. During daytime, the plant receives string sunlight. When it gets dark, an 800 lumens warm white light bulb illuminates the porch. This Venus flytrap therefore experiences very little darkness. Can Venus flytraps remain healthy if they a...

However, even when using platforms like Internet Archive or Google Books, it's often difficult for me to find what I'm looking for, an...

Q: Computing an integral using differential under the integral sign

Teodoras PauraThe following integral is in question. $$I(x) =\int_0^x \frac{\ln(1+tx)}{1+t^2}\,dt$$ My attempt is finding $I’(x)$ which is $$I’(x) = \int_0^x \frac{t}{(1+t^2)(1+tx)}\,dt + \frac{\ln(1+x^2)}{1+x^2} $$ Now we can use partial fraction decompostion for the first integral. $$\frac{t}{(1+t^2)(1+tx)} ...

Q: Excluding some values from the quintile classification in QGIS

Geo_itI am working in QGIS with a vector layer of about 8000 records and I would like to use the graduate symbology, equal count (quantile, 5 classes) with a variable that contains some records to which the value 888888 is associated with missing data (these are about 3-4 cases). How can I exclude thes...

Q: Should I wait to send a revised manuscript?

Dervin ThunkWe submitted a manuscript to a well-known journal. The first round of reviews came in 6 months later. We revised, resubmitted in about 3 weeks (they gave us two weeks to r&r) and we got a new, minor revisions (after 3 months) asking us to do something that wouldn't take much time: add a couple of...
