What is the angle between the two wings of Lorenz's strange attractor?
How to make the function of the planes from the lorenz attractor
Referee says the proof is wrong, but it is not, what to do? About 3 months ago, my co-author and I submitted a mathematical paper to a journal. Yesterday, we got the editor's response and the paper has been rejected. The reason is that the referee thinks that our results are wrong or trivial.  However, we carefully read the referee's report and we conclude that the "errors" pointed out by the referee are not errors at all and that our proofs are correct. In all modesty, we think that the referee understood very poorly even the statements of our theorems.  Personally, this is the first time that such a situation occurs to me. I already have four papers published in such journal and the reports I got from the referees have been always really accurate.  What do you think is the best thing to do? Forget about and try another journal? Write an e-mail to the editor explaining why we disagree with the decision? Other ideas?  EDIT: Thank you very much for all your answers. At the end, we submitted our paper to another journal with only some slight edits we have already planned to do independently by the referee's report. Blender 2.8 - AWS EC2 command line EEVEE render I have been trying to get this to work for a couple days now. I have an EC2 P2 instance with NVIDIA CUDA configured by default, its a Deep learning Ubuntu AMI. This OS does not have a GUI so everything is via terminal.  I downloaded Blender's 2.8 TAR file for Linux and set it up on the EC2 instance. And ran the following command from the directory where the TAR file is extracted:   ./blender -b -noaudio /home/ubuntu/file.blend --render-output . --engine BLENDER_EEVEE --render-format PNG --verbose 4   All I see in the output is this:  Blender 2.80 (sub 75) (hash f6cb5f54494e built 2019-07-29 17:17:04) found bundled python: /mnt/blender/blender-2.80-linux-glibc217-  x86_64/2.80/python Read blend: /home/ubuntu/file.blend  Blender quit   Don't know why its quitting but I am unable to debug this any further. Any help would be appreciated.  UPDATE: As per @rjg's recommendation, ran the following command:  ./blender -b -noaudio /home/ubuntu/file.blend --render-output . --engine BLENDER_EEVEE --render-format PNG -f 1 --verbose 4   Got the following error:  Blender 2.80 (sub 75) (hash f6cb5f54494e built 2019-07-29 17:17:04) found bundled python: /home/ubuntu/blender/blender-2.80-linux-glibc217-  x86_64/2.80/python Read blend: /home/ubuntu/file.blend Unable to open a display Aborted (core dumped) How to disable javascript modal popup ads How do I install Adobe Air using "Ubuntu Software Centre" I tried:   Launching Ubuntu Software Centre I typed in "air" and found "adobe air" It says "available from the 'maverick-partner' source. and has a button "use this source" I clicked "use this source", I saw a "in progress (1)" icon come up in the side bar, and disappear, but nothing happened/changed.   I'm stuck.  I have actually already added the maverick-partner source to apt so I could install sun-java6-jdk. Ramanujan Summation It seems that under the light of  the following is plausible:  $$1 + {2^{2n - 1}} + {3^{2n - 1}} +  \cdots  =  - \frac{{{B_{2n}}}}{{2n}}(\Re)$$  Alas, I can't really find any concrete definition of Ramanujan Summation. Could someone provide a small explanation? Custom kernel: fails to load firmware when module built-in I'd like to have all my modules built-in, but this fails with iwlagn:  iwlagn 0000:03:00.0: request for firmware file 'iwlwifi-6000-4.ucode' failed. iwlagn 0000:03:00.0: no suitable firmware found!   The microcode file exists in /lib/firmware and the whole thing works just fine if I compile iwlagn as module. I have no idea where it's looking for the file or what's wrong - any ideas? Supersymmetric Localization (Mirror Symmetry) I'm reading Chapter 9 of . As you can see in eq. (9.30) his model for SUSY is  $$\begin{align} \delta_\epsilon X &amp;=\epsilon^1\psi_1 + \epsilon^2\psi_2\\ \delta\psi_1 &amp;= \epsilon^2\partial h\\ \delta\psi_2 &amp;=-\epsilon^1\partial h.  \end{align}\tag{9.30}$$  I understand that if $\partial h\neq 0$ it is possible to see that partition function vanishes, in particular, there is a total divergence:  $$ \int \mathrm{d}\hat{X}e^{\frac{1}{2}(\partial h(\hat{X}))^2}\frac{\partial^2 h(\hat{X})}{(\partial h(\hat{X}))^2}. \tag{*} $$  The implication that a total divergence yields vanishing integral, it is a bit strange, because, since every function that admit a primitive is a total derivative. What is the meaning of that implication? Then why $(*)$ vanishes? It seems to me that, in general, $$ \int \mathrm{d}(h')\frac{e^{\frac{1}{2}(h')^2}}{(h')^2}\neq 0. $$  Then, again, when he claims that if there is a $x_0$ such that $h'(x_0)=0$ we can use again the argument of the total divergence, why doesn't he keep in account that, removing a small neighborhood of $x_0$, give us some contribution at the border of that neighborhood (two points)? Where does the extra kinetic energy come from in a gravitational slingshot? PHP: Return all dates between two dates in an array Recommendation for mobile prepaid SIM card for smartphone + home calls in Germany What SIM card would you recommend for a smartphone user for travel in Germany?  It would be probably the only or the most important connection to the Internet, so large amounts of data and relatively fast transfer is an issue.  I need to stay in touch with friends and family, so the calls to other EU countries should be as cheap as possible.   For to the first criteria, I found the T-Mobile offer interesting. The internet costs 10 Euros/month and after reaching the transfer limit it stays relatively fast. According to tests (Galileo from Pro7, AFAIR) it has also the best coverage. However, calls to other countries are very expensive.  For to second criteria, Lebara and Mobilka are interesting. The calls are very cheap, but there are problems with signal strength in many locations, where T-Mobile has no problem. The voice quality, at least in Lebara, is also limited. They both have mobile internet with unlimited transfer, but after reaching the high speed limit, the transfer is reduced to 64 kbps, which is too slow.  I've found out that O2 has foreign calls at moderate prices, but I haven't yet checked for details. There are so many other options, making it is hard to compare them all without spending the whole weekend on it. So, if someone has found a better option than having 2 SIM cards and constantly switching them, this answer would be greatly appreciated. Why does the classical path give the dominant contribution in the path integral? Why is it that the classical path gives the dominant contribution in the quantum mechanical path integral?

There would be the possibility to modify all the views .tpl.php files but I hope there's an easier way to do this.   I also read about the semantic views module but I didn't understand how to configure my view with it so that i get only the needed markup as output. it didn't seem to have any effect. The following code helps me validate an XML file with an XSD schema.  XmlReaderSettings settings = new XmlReaderSettings(); settings.Schemas.Add(null, xsdFilePath); settings.ValidationType = ValidationType.Schema; settings.ValidationEventHandler += new System.Xml.Schema.ValidationEventHandler(settings_ValidationEventHandler); XmlDocument document = new XmlDocument(); document.Load(xmlFilePath); XmlReader rdr = XmlReader.Create(new StringReader(document.InnerXml), settings);  while (rdr.Read()) {  } isValid = true;   The ValidationEventHandler also tells me what the errors are, but doesn't tell me on 'where' or 'on which line' they are located. Is there any way to get the line number where the XML fails to be validated? Uniform convergence of $\sum (-1)^nf_n(x)$ on $[0,1]$ where $f_n(x)=x^n(1-x)$. Let $f_n(x) = x^n(1-x)$ and $\sum (-1)^nf_n(x)$.  I showed that this series point wise.  Case1) $x=1$ $$ f_n(1)=0 \, , \sum{(-1)^nf_n(1)} = 0 $$ Case2) $x\neq 1$ $$|f_n(x)| \leq |x|^n$$ since $$\sum |x|^n$$ converges, By abosultely convergese test $\sum (-1)f_n(x)$ converges.  I want to show that this series uniformly converges on $[0,1]$. Is it feasible to build a stream cipher from a cryptographic hash function? A few years ago I devised a symmetric-key system that worked like so:  H()   = some hashing function h     = the number of bits in the result of H() key   = bits to be used as a key ^     = the XOR operation +     = concatenation len() = the length function (in bits)  max = ceiling(len(cipertext) / h) pad = pad_0 + ... + pad_max pad_0 = H(key) ^ H(plaintext) pad_n = H(pad_(n-1)) cipherpart_n = plaintext_n ^ pad_n ciphertext = H(plaintext) + cipherpart_0  + ... cipherpart_max   Basically, it builds up a "pad" based on the hash of the message and hash of the key and XORs the message against it.  I am not actually an expert, so I was wondering why an approach like this isn't very common. A gerund or use a regular noun? Which of these is correct or more natural?

SOQL result ordering in the absence of an Order By clause In the absence of an  in a SOQL query, what order will Salesforce return results in?  Clearly if ordering is important then Order By should be specified, but I recently encountered a question about what the order would be if it was undefined.  My initial thoughts were Salesforce would return them in whatever order suited them. Much like .  For simple queries this would typically line up with the creation date descending and the Id ascending. For more complex queries it would depend on the joins being performed.
