I submitted the manuscript to a Springer medical journal. One month later, major revision was suggested. Then I re-submitted the revised form. One day later, the status changed as "editor assigned". Finally, this status did not change for 4 weeks. What does it mean? Has the assessment started yet?  Thanks..
What steps does a manuscript typically go through from submission to publication (or rejection) in a typical journal? How are these steps referred to, in particular by editorial systems, and how long do they each typically take?  Note that this question is about the typical situation and hence not about:   Journals with an atypical workflow, e.g. those that allow for an instantaneous reviewer–author interaction. Exceptional steps or rare occurrences such as withdrawal or .   This is a canonical question on this topic as per . Due to its nature, it is rather broad and not exemplary for a regular question on this site. Please feel free to improve this question.
Derivative of a factorial What is ${\partial\over \partial x_i}(x_i !)$ where $x_i$ is a discrete variable?  Do you consider $(x_i!)=(x_i)(x_i-1)...1$ and do product rule on each term, or something else? Thanks. Can you attach a UIGestureRecognizer to multiple views? Salesforce - Maximum simultaneous requests callout limit Salesforce says      Maximum simultaneous requests to URLs with the same host for a callout   request is 20   Statement is very simple to read but it is not very clear as to what it means.

Stack Exchange API too many requests from this IP address I am using the Stack Exchange API to get Stack&nbsp;Overflow data, but I am getting "too many request from this ip" after making only five requests. I got JSON content like this:  {u'error_id': 502, u'error_message': u'too many requests from this IP, more requests available in 68492 seconds', u'error_name': u'throttle_violation'}   I made the following requests to Stack&nbsp;Exchange without an access token:   "" ---> 2 times called this API "" --> 3 times called this API and on the 4th call I got an exception QM without complex numbers I am trying to understand how complex numbers made their way into QM. Can we have a theory of the same physics without complex numbers? If so, is the theory using complex numbers easier? How to set static IP address? I have configured network adapter of guest Ubuntu to work in a bridged mode so I could ssh to it from the host machine.   The problem is that the guest Ubuntu ip address keep changing.   Even though it changes  within a very short range 192.168.0.4-10 it is still takes time to configure Putty and other programs each time.  Is there a way to make the guest Ubuntu ip address to be static?  My guest OS has the full GUI. Integrating $\int^2_{-2}\frac{x^2}{1+5^x}$ $$\int^2_{-2}\frac{x^2}{1+5^x}$$  How do I start to integrate this?  I know the basics and tried substituting $5^x$ by $u$ where by changing the base of logarithm I get $\frac{\ln(u)}{\ln 5}=x$, but I got stuck.  Any hints would suffice preferably in the original question and not after my substitution.  (And also using the basic definite integrals property.)  Now I know only basic integration, that is restricted to high school, so would prefer answer in terms of that level. Order and degree of a differential equation Here is a question in my book  Find the order and degree of the differential equation $$y=1+\frac{dy}{dx}+\frac{1}{2!}{\left(\frac{dy}{dx}\right)}^2+\frac{1}{3!}{\left(\frac{dy}{dx}\right)}^3+\cdots$$  At first sight we can conclude that the order is $1$ and the degree is undefined as  as the power of $\frac{dy}{dx}$ continues to increase and has no limit.However  my book gives the following solution  Rewrite the DE as $$y=\exp\left({\frac{dy}{dx}}\right)$$ $$\implies \frac{dy}{dx}=\ln y$$ whose order and degree is 1 .  Now ,I completely agree with this solution however I find it rather counterintuitive to my first line of thought .If the book is correct how can it be justified to prove my intuition was wrong? Transparent model when exporting fbx file to Unity So I have this shark model which I animated and ready to export it on fbx and transport it to Unity.  But When I put it on Unity, It looks transparent like this.    Many of the solutions online say that the problem is because of my faces, and they told me to recalculate it or something, but normals are just fine. Is there any other solution?  here's the blend file: Is the total energy of the universe zero? In popular science books and articles, I keep running into the claim that the total energy of the Universe is zero, "because the positive energy of matter is cancelled out by the negative energy of the gravitational field".  But I can't find anything concrete to substantiate this claim. As a first check, I did a calculation to compute the gravitational potential energy of a sphere of uniform density of radius $R$ using Newton's Laws and threw in $E=mc^2$ for energy of the sphere, and it was by no means obvious that the answer is zero!  So, my questions:   What is the basis for the claim &ndash; does one require General Relativity, or can one get it from Newtonian gravity? What conditions do you require in the model, in order for this to work? Could someone please refer me to a good paper about this? Bisecting K-means using Dynamic Time Warping I'm trying to cluster time series of different length and I came up to an idea to use DTW as a similarity measure, which seems to be adequate, but the thing is, I cannot use it with K-means, since it's hard to define centroids based on time series which can have different length/phase. So I was thinking about Hierarchical clustering, since it seems appropriate to combine with DTW, but it's not scalable. So my next thought is to try with bisecting k-means that seems scalable, since it is based on K-means step repetitions. My idea is next, by steps:   Take two signals as initial centroids (maybe two signals that have smallest similarity, calculated using DTW) Assign all signals to two initial centroids Repeat the procedure on the biggest cluster   In this way I could use DTW as distance measure, that could be useful since my data may be shifted, skewed, and avoid calculating centroids. At the end I could take one signal from each cluster that is the most similar with others in cluster (some kind of centroid/medioid).  What do you think about this approach and about the scalability? How to Install Octave in El Capitan? File changed listener in Java How to sum a variable by group Terminal method of formatting storage drive I want to know how to format a storage drive from the terminal. Helpful things to provide in the answer would be often used options for commands and base knowledge that one can use to extrapolate future uses. Specifically I would like to know how to format in the different file systems such as NTFS, FAT32, EXT4, etc. Information on how to partition the drive via terminal is also wanted.  I am trying to format a high capacity external hard drive (EHDD) into NTFS - from the terminal.   I know I can use gparted for this as well as other GUI programs, but I still want to now how to do it from the terminal. Using Regular Expressions to Extract a Value in Java I have several strings in the rough form:  [some text] [some number] [some more text]   I want to extract the text in [some number] using the Java Regex classes.  I know roughly what regular expression I want to use (though all suggestions are welcome). What I'm really interested in are the Java calls to take the regex string and use it on the source data to produce the value of [some number].  EDIT: I should add that I'm only interested in a single [some number] (basically, the first instance). The source strings are short and I'm not going to be looking for multiple occurrences of [some number]. Does "corresponding author" carry an implied meaning? where do I use Database. Methods? I m trying to understand where we use following Database.Methods. I know if we want to insert a record to an object we use DML Statement. What i want to know is why/where we use Database. methods. It might be silly question. Database.saveResults Database.insert Database.query Database.Query Database.error   really appreciate the inputs. Thanks a ton in advance. Using Squeeze Theorem to show the following limits Consider a function f (x) defined on R satisfying:   for all x distinct 0.  Calculate: lim f(x) with x→∞ and limf(x) with x→−∞   Issue information:   if x → ∞ then we can consider | x | = x  if x → -∞ then we can consider | x | = -x  I can use x² = | x |? Why do I get a black rectangle instead of my external picture? I write some of my network notes in TeX. I wanted to make a table, and inside it insert an image:   .

I don't know what is wrong, cause my image is 100% in the same dir, as my *.tex file.
