Guilty Gear Xrd (Japanese: ギルティギア イグザード, Hepburn: Giruti Gia Iguzādo) is a fighting video game sub-series by Arc System Works and part of the Guilty Gear series. Guilty Gear Xrd was developed using Unreal Engine 3, with cel-shaded graphics in place of the series traditional hand drawn sprites. Following the storyline of the last game in the series, Guilty Gear 2: Overture, it introduced seven new characters.
The first Xrd game, Guilty Gear Xrd -SIGN-, was released in arcades on February 20, 2014 as the 5th main installment, and for the PlayStation 3 and PlayStation 4 in Japan and North America in December of the same year. A digital-only release happened in Europe in June 2015, and it was brought to Microsoft Windows via Steam on December 9, 2015. The game has been praised for its cel-shaded graphics and approachable gameplay, but criticized for its non-interactive story mode and smaller roster of characters.
A sequel follow-up, titled Guilty Gear Xrd -REVELATOR-, was released on consoles in May 2016 in Japan and June 2016 elsewhere as the 6th main installment. An update title to -REVELATOR- titled Guilty Gear Xrd REV 2 was announced at Arc System Works Fighting Game Award 2016 on January 14, 2017 and released for Arcades in March 2017, while PS3, PS4 and PC versions were released worldwide at the end of May 2017. The REV 2 update patch for those who bought -REVELATOR- on PlayStation Store or Steam was released as a paid DLC. The PS4 also received an exclusive physical disc version.

    A Question about crystal structure of long chain fatty acids (XRD)

    Hello, we are studying potato periderm before/after digestion and dewaxing and native vs wounded. One of the techniques is XRD, hence my user name. Among other things we are trying to use XRD to determine the arrangement of fatty acids, esters, and other long-chain aliphatics that are present...

    I Why XRD peaks are so sharp?

    I was reviewing an old topic for me that's x-ray diffraction, and one doubt I always had in my mind arised again. When introducing the Bragg's law, the typical explanation is that the x-ray waves reflecting in two adjacent planes interfere with each other, leading to a fully constructive...

    A Powder XRD sample prep question

    Hello, I have an unusual case in that I am using XRD to study plant skins before and after certain chemical treatments. So the resulting pattern will have a lot of amorphous regions but also some characteristic peaks showing the presence of fatty acids, etc. Basically I grind everything to a...

    A Powder XRD data Analysis

    I studied an elementary course as an introduction to Solid State Physics. Now I have powder XRD data to practice crystal structure determination. I am going to do this alone in my computer. I want to know what software to use (free software) with manual of course. Any help please?

    I What does peak intensity mean in qualitative XRD?

    If diffraction angle 2θ represents Miller indices, what does intensity represent particularly in the context of quantitative XRD?

    XRD - Color change after test

    I was performing XRD earlier, and I came across this odd occurrence in the powders that were being inspected - After it was performed, the crystalline powder I had been testing had gone off color into this yellowish appearance (Originally was white). Upon disturbance, the powder become white...

    How to convert XRD results in .txt format to .dat or others?

    I had some precipitate samples analyzed for XRD and the operator sent me the results in .txt format containing the 2θ and intensity data. I want to plug the data to QualX software but apparently it cannot read data in that format. Is there any way to convert the data to compatible formats (e.g...

    XRD sample preparation

    I have some precipitate samples that I wish to analyze for XRD. I collected them by filtration of a slurry. Through the filtration, the precipitates "cemented" on the surface of the filter pad so the samples I collected are not exactly in powdered form, which I believe is the ideal form to do...

    XRD Data Analysis Question

    The major diffraction peaks of my sample have essentially the same 2θ values as the reference (graphically), but have different heights. Can it still count as conclusive evidence that my sample matches the reference? Or does it suggest that my sample is a different substance? Also, as a side...

    Powder XRD

    Hello, everyone! Let's say I have an XRD pattern which has broad reflections. I dunno what material it is (don't know what temperature and conditions it is made). How to know whether those broad reflections are from nanomaterial or amorphous material?

    Determine the lattice parameter of Tetragonal system

    As a part of our exercise we need to determine the lattice parameter of the given xrd peaks (http://bama.ua.edu/~mweaver/courses/MTE481/Lab2_PP.pdf [Broken]. the last page of the link), heres the peak data: 2theta 23.73 39.23 46.36 56.69 62.31 71.1 76.15 84.35 89.2 97.29 102.21 110.83 115.9...

    Determine Crystal structure of non-cubic crystal in XRD plot

    Given only 2theta and intensity, how to know the crystal structure (except cubic) of non cubic crystals, and also determine their lattice parametera,b,and c, if there's a link or website discussing techniques to determine crystal structure of all crystals, please don't hesitate to put it here...

    X-Ray Diffraction peak width due to micro-strain

    I understand that the peak-width of diffraction data increases with increasing amounts of heterogeneous, localized (AKA "micro-") strain. So, if you have a single crystal with atomic impurities in it that each create micro-strain in the lattice, you would expect the amount of peak-broadening...

    Does anyone have experience with DBWS software for Rietveld refinement?

    I'm analyzing data from XRD on a FeSeTe sample, and can't figure out how to match the calculated intensities with the observed ones. I'm having a hard time with this program, can someone help me?
