-Our protein from other species does what we expected in E.coli.
-The function is predicted from the blastp search. We found it has an extra domain so I wonder is it reasonable to study a protein from other species in E.coli?
-My concern is that the domain may act differently in the original species. What we found in E.coli may not be true in its native host.
-Our goal is to engineer the protein, however, other concerns that we should not engineer the protein if we don't know its function.
I have submitted a manuscript to a reputed journal. After 2 months of peer review process, the response was “moderate revision has been requested” and they told me that the new version is required within 1 month.
After making the necessary adjustments, I have resubmitted the revised manuscript back on the 14th of October 2017. On the 21st of October the status changed from “with editor” to “under review”. To date (16th December) the status is “under review”.
In fact, I had made some readings about late reviews, I found that reviews are normally due 14 days after the invitation is accepted by the reviewer.
Should I worry about manuscript rejection?
Thanks in advance for your help

According to Steven W. Smith, in his book: The Scientist and Engineer's Guide to Digital Signal Processing, when designing a digital filter, "Good performance in the time domain results in poor performance in the frequency domain, and vice versa", and one needs to find a good trade-off for one's needs; and from what I understood, bad performance in the time domain means that the signal's waveform will be altered, meaning it will be somehow distorted after going through the filter. Additionally, the filter's step response is of the most importance when it comes to achieving good performance in the time domain. http://www.dspguide.com/CH14.PDF
So, after I designed two filters with matlab that aim to rid a signal from the electromagnetic interference (lowpass), and the DC component (highpass), and thinking that linear phase filters preserve the shape of the signal because all frequency components are shifted equally, so I went with the FIR filter option, and by using the function fircls1 that allows for defining the ripple levels in the passband and stopband, with the former being the concern for preserving the amplitude levels of the different frequency components, I thought I am getting the best possible "time domain" response, and the shape of the waveform in the time domain is as intact as could possibly be, moreover, I used an adequate number of points in the filter kernal to get the roll-off I desired, and after all that I came across that phrase in the first paragraph, this time I paid more attention and said let's have a look at the step response of the filter. Before I was solely concerned about the frequency response, ripple and stopband attenuation, etc.
I am attaching the step responses of my lowpass filter (left) and highpass (filter) right, and I would like to understand, what did I do wrong? I have looked at the filtered signal and it looks good, it is delayed considerably, and I know FIR filters requires longer execution time, but I am working on it offline, as in not in real-time, and I think I optimized the frequency response, as I mentioned, pretty much, so if that phrase means what I think it means, then the signal is not preserved and its waveform is some how distorted, and I cannot have that for the intended application, so could some one please help me make sense of these seemingly contradictory understandings. Thank you very much!
In the literature and in the RG site pages, the “kinetic model” term sometimes occurs. Using it, authors of laboratory studies would like to let riders know beforehand that they don’t state that this model describes the real mechanism but only propose the model as if capable of predicting the reaction rate under some conditions.
However, on the one hand, it is a question whether the irresponsible proposal of a mechanism is useful for the catalytic science and, on the other hand, maybe, it would be more useful to have an experimental unit real tube filled with a catalyst or an experimental shelf with a catalyst at the chemical plant and to determine the map of the catalyst productivity under different ambient conditions with no models.

I want to start a philosophical discussion and ethical debate on the reasoning behind why humanity should and must become a multi-planet species.
- What do you think is the most profound and captivating reason(s) that you have to justify SpaceX and Elon Musk's goal of making humanity a multi-planetary species?
Elon said during the 68th Annual ISC on September 29th 2017:
"I think fundamentally the future is vastly more exciting and interesting if we're a spacefaring civilization and a multi-planet species than if we are not. You want to be inspired by things. You want to wake up in the morning and think the future is going to be great."
I agree with him here, but I think there is something more profound and captivating that must be addressed with regards to becoming a species that lives on more than just one planetary body. Other questions we may want to consider to help us reach this answer include:
- What are the ethical considerations we must address before colonizing other worlds?
- Do humans really deserve another planet to potentially ruin, or even sustainably terraform, if we cannot even figure out how to sustainably balance our own home world?
- One might ask why doesn't Elon use his genius to create new technologies that will advance the human race by solving some of the Earth's worst problems?
- Has he simply given up on this planet and does he therefore want a clean slate to build up from?
- Does Elon think that technological advancements resulting from the drive to become a spacefaring civilization (i.e. propellant production via. CO2 sequestration powered by 100% solar energy systems) will eventually rebound to help the Earth?
- Must we start colonizing Mars now (i.e. beginning in the year 2022) like Elon's timeline suggests? Potentially, if we wait too long, technologies to reverse climate change on Earth may not have advanced enough without the excitement of being spacefaring...
Lets see what everyone thinks about this, and let's keep it civilized in here. Try and get real profound!
Although its a very basic question but i think it must be discussed in forum like this, that before we start studying any property like electrical, optical, thermo-mechanical etc. of any sample, what must be kept in mind regarding material characterization e.g.
Electrical and Magnetic Techniques
Spectroscopic Techniques etc.
Like If one is studying electrical properties than what characterization techniques like Scanning Electron Spectroscopy (SEM), Transmission Electron Microscopy (TEM), FTIR, XRD, EDS, EDXA, EDXMA, XPS, etc. one must have to go through ?
and similarly for other properties......?

In order to successfully teach young students as future engineers, we should, in my view, recognize as precisely as possible their expectations, their hopes and their level of knowledge about the role of the engineer in society at the start of the learning process.
Problems concerned with recognizing, identifying, analyzing or assessing human needs are investigated by many authors in various approaches. The needs are seen as a problem of social sciences (considering human needs as something that is inextricably linked with the human existence and action). The needs are considered in economy (as one of key engine of market development). The needs are also important factor of engineering activities. The ideas like "Assessment of Needs" are also seen in medical publications (needs of patients). Since a time when I try to implement to scientific debate the idea of "Engineering of Needs", the question concerning the ethical dimension of needs is - on one hand - seen as really important, but - on the other hand - still open.

I have heard in several media that the next great revolution will be that of Artificial Intelligence. And I agree. Nowdays, the problem of building software efficiently is in somehow solved. Today's universities should be anticipating to that inevitable, but necessary, fact. Specializations at the postgraduate level are not enough. There are AI issues that need to be addressed in more detail.

If we can create a DNA computer by using DNA can we then, further use this DNA to implement Quantum Computing in this DNA Computer by using/applying Quantum Physics/Mechanics phenomena that is related to DNA? In other words - Can we create a Hybrid DNA computer that uses both DNA Computing (for storage etc.) and Quantum Computing (for speed etc.) that switches between a Quantum or Optical Quantum Computer mode and DNA Computing mode by the use/application of - "Artificial Intelligence/Neural System technology/algorithms" or/and by other way(s)?
In addition to the above - We know that through DNA/Molecular Computing we can create DNA Robots which are at a very small scale, then considering the above, can we also create Quantum Robot which is actually a DNA Robot that switches to become a Quantum Robot just like DNA Computer Switches to become a Quantum Computer in the manner that has been explained above?
In short - Can we research in DNA Nanotechnology to create a Hybrid Computer which can act, both as a DNA Computer and a Quantum Computer and can also be programmed to assemble itself as a Robot which acts both as a DNA Robot and a Quantum Robot?
* If one can create such a Hybrid System, then, can it be done through DNA/Molecular Programming OR DNA Nanotechnology?
There are circumstances when acting upon expert judgement is desirable; for example:
1. In an emergency situation where a quick decision is vital.
2. Where an innovation is being made that has not previously been proven.
However, there are other circumstances where it is better to only act upon proven knowledge; such as:
1. When making the wrong decision could be disastrous, and time is on your side.
2. Where an innovation would only work if based on scientific principals.
What are your experiences? When to act on judgement and when to act on knowledge?

Hello friends, i am a student and working on my college project. My problem is that i want to open documents like doc, docx, pdf, ppt, jpg, gif, txt, tiff, xls, dbm and some office documents on the browser which are located at my server. it means I dont want to download the document first to see the matter in it. All these document should be opened inside my web browser directly.
I know about google document viewer which provides cloud services for that, but their are some limitations for their use. there are many other cloude services , but they are not fullfilling my need. Is there any api that can help me? By the way my project is in J2EE and server is tomcat, database is Mysql. and my plateform is Windows 7.
If i am able to edit those document from client side , then it will be an extra help to my project.
If you have any matter that can help me then please send me it on [email protected].
Thanx in advance!!!

I would like to discuss a best possible method for consumer behavior modelling.
For example, if a consumer goes same super market all the time, i would like to model the purchasing behavior so that the model can accurately predict the goods he may buy next time he visits the store.
The problem may be approached from the patter recognition point of view also.
While buying an automobile for self, is the knowledge of technical specification like [email protected], Torque, power to weight ratio matter? Do consumers really give any importance to these tech specs?

we define a wave vector as a complex number, when EMW traverses in conducting media whereas a real number when it traverses in free space.so I want to know the physical meaning of complex number. a complex number contains a real and a imaginary part! then, how propagation can be imaginary?
Is it possible to write arbitrary data as output to a SAP model using OAPI (or some other method) and then display those data graphically within SAP? I know it is possible in other dedicated pre- and post-processors (e.g. FEMAP), but I am working with an existing model and the rest of the team is fixed on using SAP for analysis and post-processing.
Essentially we have a number of offline calculations and we would like to display the results of these calculations graphically on the SAP model. Any suggestions would be appreciated.
I am trying to find examples of systems of linear higehr order differential equations.
That is, systems in the form;
Α Χ'''(t) +B X''(t) + C X'(t) + DX(t) = U(t)
Α Χ'''(t) +B X''(t) + C X'(t) + DX(t) = 0
where A, B, C, D are matrices and X(t) is a vector variable, i.e.
Χ(t)=[v1(t) v2(t) v3(t) ]T
Many such systems arise in mechanical engineering, like spring-mass oscillation systems, spring-mass systems with dampers etc, but all of them are 2nd order differential equations.
Can anybody help me find systems of order 3 or higher? The free parameter t does not necessarily have to be time. They can be engineering, biological, economic systems, whatever!
Please provide references too.

I have dataset of author and their coauthor. I made a graph of this dataset. It contains a huge no. of cycles. I have tried JGRAPHT java API to find these cycles by using Johnsons Algorithm but failed on real data of about 577 publications. It is working on quite small set of authors and coauthors data.
If anybody know some good API in java or in any language or suggest me some other good algorithm for the said purpose.
Can I use community detection algorithm for this purpose or strongly connected component??
Thanks in advance..

Dear RG friends:
In two weeks time, I am all set to conduct a technical session on Analysis.
I plan to deliver a long lecture on "Fixed Point Theorems". Of course, Banach fixed point theorem is useful to establish the local existence and uniqueness of solutions of ODEs, and contraction mapping ideas are also useful to develop some simple numerical methods for solving nonlinear equations. Are there any other interesting science / engineering applications?
Kindly let me know! Thank you for the kind help.

In general, light is produced for household purpose with bulb, CFL, tube, LED etc from electrical power. There is a big portion of world that lives in dark after sun sets. These people do not want electrical power, they want light first.
Is it possible to create a pollution free light without electric power and without burning something. Light that is sufficient to illuminate a 12 x 12 feet hut without an electricity connection. Light that is very very cheap (not more than $1 per week and 8 hours per day)….Don’t tell solar or known things….suggest something wild…some new idea….innovative…no power only light….Just for the sake of discussion….

I'm working on MMCs with Al2O3 reinforcing particles in Al matrix. In articles it is mentioned that for better wettability of Al2O3 with molten Al it's effective to add Mg powder. How can I avoid attaching powders at the nozzle tip which can block injection of powder?
The monomer I used was heptylamine.
I did for warming up the monomer by immersed the bottom flask in the water bath. I used the heating tape to warmed the SS piping as well and the SS piping had the heptylamine odor strongly.
However, it showed air plasma reaction (pink color) once turned on the RF power. Heptylamine seem doesn't flow into the chamber because it doesn't have any odour of Heptylamine inside the chamber.
How can I improve the system to gain more monomer flow into the chamber? Any methods to tighten the bottom flask to holds the stainless piping？(Figure 1)
