SixPack PCA
by Andrew 29 Apr '10

29 Apr '10

Nagappan, I'm by no means a statistical expert. There are some rules of thumbs in the literature regarding what Spoil value to believe in or not. Some resources that you can look up: 1. Beauchemin, S.; Hesterberg, D.; Beauchemin, M., Soil Sci Soc Am J 2002, 66 (1), 83-91. (( in the above work they included standards which had SPOIL values greater than 6, so they would have rejected a standard with a value lower than 6)) 2. Malinowski, E. R., Factor Analysis in Chemistry. Wiley: New York, 2002; p 432. I might be wrong on this but when these programs use the formulas for calculating F-values and SPOIL values, they assume that all points are independent. One question that comes up sometimes is "How many independent points are there in a XANES spectrum?" In EXAFS many people use the Nyquist criterion. And what I'm getting at is you have to be cautious in using a rule of thumb for the XANES analysis. If there are other techniques you can use to help you identify what is in your sample try those as well. The manual on Athena also points out that the number of independent points collected in a XANES spectrum is difficult to determine. Without additional information: the quality of the data collected (the signal-to-noise), what edge you collected your spectra, are you fitting standards that you collected in the same set of runs as your samples, I think it's difficult for anyone to go into further depth. Please look up the above two references, this should at least give you a better idea. Hope this helps! Andrew Campos

SixPack PCA

Hello, In the Target Transform step of PCA analysis using the SixPack program, I am trying to understand the significance of the parameter called SPOIL? Can this parameter can be used as a measure of merit of the target? If so, what range is acceptable. Also what does it mean if SPOIL value is zero? Thanks Nagappan

27 Apr '10

Hello All: Please share this announcement with anyone whom you feel might be interested. I am positive that I am not getting this out to the entire core shell spectroscopy community. Note hat the abstract deadline has been extended until May 15 for oral presentations. The Ed Stern Symposium will feature the following invited speakers: Dr. Mali Balasubramanian, Argonne National Laboratory Prof. Jerry Seidler, University of Washington Prof. Anatoly Frenkel, Yeshiva University Dr. Ken Kemner, Argonne National Laboratory Prof. John Rehr, University of Washington Prof. Michael Paesler, North Carolina State University other invited speakers will include Dr. Corwin Booth, Lawrence Berkeley National Laboratory Prof. James Penner-Hahn, University of Michigan and more to come... ---- Conference Announcement ---- 1st North American Core Shell Spectroscopy Conference to be held jointly with the 59th Denver X-ray Conference 2-6 August 2010 Ι Denver Marriott Tech Center Hotel, Denver, CO <https://resweb.passkey.com/Resweb.do?mode=welcome_ei_new&eventID=1454471> The first North American Core Shell Spectroscopy Conference will be held jointly with the 59th Denver X-Ray Conference, 2-6 August 2010. The conference will feature poster sessions as well as oral presentations and students, in particular are encouraged to participate with oral presentation submissions. All topics relating to core shell spectroscopy are welcome, including: · X-ray Absorption Spectroscopy · X-ray Fluorescence Spectroscopy / Fluorescence Mapping · Resonant Inelastic X-ray Scattering / X-ray Raman Scattering · X-ray Magnetic Circular Dichroism The conference will feature a special session and dinner in honor of Ed Stern. The list of invited speakers for this special session includes Dr. Mali Balasubramanian, Argonne National Laboratory Prof. Jerry Seidler, University of Washington Prof. Anatoly Frenkel, Yeshiva University Dr. Ken Kemner, Argonne National Laboratory Prof. John Rehr, University of Washington Prof. Michael Paesler, North Carolina State University Participants will be able to attend Denver X-Ray Conference Sessions being held in adjacent rooms. Details of the oral presentation sessions will be posted on the DXC web site <http://www.dxcicdd.com/default.htm> as they are available. Students are able to register for a reduced cost, are eligible for special student room rates <http://www.dxcicdd.com/10/details.htm#studentrooms>, and may apply for funding <http://www.dxcicdd.com/10/files/2010-DXC-Student-Travel-Grant-application.p…> to attend the conference.

We are organizing this conference to provide an opportunity for researchers in North America to gather and present their research in years when there is no International XAFS Conference. One of the major goals is to have a high degree of participation from students and postdoctoral scientists in both the oral and poster sessions. On behalf of the organizing committee, I would like to invite you to give a talk at one of our sessions. Since we are leaving the logistical organization of this conference to the ICDD Conference Staff, we can offer the same reduced registration fee that is provided to the Denver X-ray Conference invited speakers. The plans for the conference include a symposium in honor of Ed Stern on Tuesday, August 3, a poster session and a series of oral sessions running concurrently with the Denver X-ray Conference sessions. We hope that you can accept this invitation, and look forward to seeing you in Denver. Sincerely yours, Carlo Segre, for The Organizing committee. -- Carlo U.

fitting
by mohamed sobhy 23 Apr '10

Dear all I am trying to fit some data of coordination number 8, but I always find the fitting of the first shell give the coordination number only about 0.5. I do not know what is wrong. Do I need to fit first and second and third shells altogether, and if that is right how Can I do that?? Thanks

Data file for Arrojadite with screenshots

Dear Bruce, Thank you very much for your reply. I used structural file from ICSD database (http://icsd.ill.eu/icsd/index.php?action=Details&id[]=50276) I have attached the same file with this mail also. The following screenshot shows the core atom (Fe) i selected to get scattering paths. The following screenshot shows the actual problem : The Degeneracy (Deg : N) is 1 or 2 for all the paths which is not true from the structure. Many more thanks in advance.

Re: [Ifeffit] Emission spectra of Cobalt

Hi Timna, The energy arguments for the XES in FEFF84 are energies of the valence electron relative to vacuum, so emin should be a negative number. Try XES -20 0 0.3 This should capture at least some of the XES. You can play with emin to get the range right. Note that the number of energy points in FEFF84 is fixed, and if you specify a small energy step (the third parameter) you will not achieve the full range that you specify.

We are organizing this conference to provide an opportunity for researchers in North America to gather and present their research in years when there is no International XAFS Conference. One of the major goals is to have a high degree of participation from students and postdoctoral scientists in both the oral and poster sessions. On behalf of the organizing committee, I would like to invite you to give a talk at one of our sessions. Since we are leaving the logistical organization of this conference to the ICDD Conference Staff, we can offer the same reduced registration fee that is provided to the Denver X-ray Conference invited speakers. The plans for the conference include a symposium in honor of Ed Stern on Tuesday, August 3, a poster session and a series of oral sessions running concurrently with the Denver X-ray Conference sessions. We hope that you can accept this invitation, and look forward to seeing you in Denver. Sincerely yours, Carlo Segre, for The Organizing committee. -- Carlo U.
