Dear Daniel,

with all due respect, I do believe that you are making several mistakes in
your argument.

English is not my native tongue, but I suspect that there is a substantial
difference between "author" and "signatory".  What people are asked to do
here is essentially to sign a petition, not to become a co-author in
traditional sense.  There were 39 signatories to the US Constitution,
certainly not all of them are considered its authors.

Furthermore, most structural biologists are trained scientists and it is
rather routine part of our job to evaluate research we are not exactly
experts in.  I am not a climatologist, but I do take exception to your
assertion that I am therefore automatically too ignorant to understand
basic concepts that pertain to global warming and climate change.  A
climatologist wouldn't instantly know what B-factors are, but is certainly
capable of understanding the concept if you explain it.

Using physical science and its data to arrive at conclusions regarding
religion, politics and economic theory (!) is not at all embarrassing.
(And letter in question hardly does any "preaching", certainly not about
religion)

As for your demand that people stick to structural biology, may I suggest
that your reaction to exactly one entry in ccp4bb that elicited almost zero
follow up (until your comment) feels a bit overblown?  If you strongly
disagree with Dr Ripple and his colleagues, that is fine, but why shouldn't
people at ccp4bb occasionally share somewhat orthogonal information?  None
of us want to see inappropriate content, I am just not sure why you feel
that this specific post is something that needs to be purged.

Just to be clear - your post does create an impression that you might hold
the opinion that, as they say, "global warming is a hoax".  Please, let's
not have further discussion online on the specifics, but I think it might
be helpful if you could confirm or deny this.

Cheers,

Ed.

Dear Dr Himmel,

   I certainly agree that a scientist getting into the nitty-gritty of a
field outside of their training can make quite silly mistakes.  The link
you have provided to us makes an excellent example of your point.

   Dr Akasofu is a trained space scientist who studied the aurora
borealis and then spent most of his career in administration. (According
to the blog post)  Since his childhood he has disbelieved most anything
proposed by experts in whatever field.  Now we are expected to take
seriously his vague ramblings about "cycles" in climate?  What evidence
does he present?  Nothing but speculation that the climate "might" be
driven by this or "might" be driven by that.  Dr Akasofu brings nothing
to the table.

[ccp4bb] RES: [ccp4bb] Problem in real space - please sign & invite other scientists to sign this letter

2019-08-20 Thread Rafael Marques
Dear Daniel.

I really understand your point of view and I must say that I agree with it, at 
certain extent. Science is all about evidence and not what we (sometimes) want 
to see or want to believe. You are completely right when you say that, inside 
academia, evidence should be always discussed by those who have deep knowledge 
about the subject. Good science is based on good standards, and good standards 
are exactly what make our science so robust.

While I must say that it bothers me when someone who is not an expert in "my" 
field criticizes my job, I recognize that what makes what we do different than 
any religion is exactly the possibility of being criticized, both by those 
related to the field and those who might have  a good point of view.

Also, we know the rules inside the academia, how to analyze data and we know 
too that, in general, the population does not understand at all the meaning and 
the methods inside science. If we try to explain any scientific data to these 
people using our methods and standards it will be a huge failure (I can't even 
change the mind of my nephews, which after a NatGeo show started to believe in 
mermaids). When we deal with a non-academic public, we must emphasize how 
important is to make science, the good things that came from it and, most 
important, we need to be understood.

In fact, there is some discussion if the global warming is only natural or if 
it has been happening because the human activity. However, it is pretty clear 
that mankind is affecting the weather by the increase of carbon dioxide in the 
atmosphere and the large impact caused by cattle. A five minutes search on 
Google can give you back several papers, but I am going to present you only 
this one, concerned in devaluation.

HTTPS://www.scientificamerican.com/article/co2-emissions-reached-an-all-time-high-in-2018/

As scientists, we are the ones who might have no knowledge in the field, but 
the ones able to point out a critical view. When we refuse to talk to the 
population cause we are not experts is that field, someone else takes our 
place. And generally, they attack science and scientists, giving simple answers 
for complex problems. That is because they know what the population wants to 
hear. That is how Trump has become the USA president and Billboards did the 
same here in Brazil.

When we refuse to look for information, refuse to spread it to the general 
population  and hide inside the academia, we must be aware that someone, for 
sure, is taking our place. That is exactly why currently so many people believe 
that the Earth is flat and that vaccines provoke diseases. That is also the 
meaning why Greta Thunders, a sixteen years old teenager activist , is better 
known than the experts in the field. If we want to be believed we must take 
back our place. To hind is not an option.

Agreed. I support green new deal and I think we should be doing all we can to 
combat climate change,
not because I have studied it and concluded it is a problem but because some 
very smart people have, and have come to that conclusion. But I would not sign 
a letter saying that I have concluded, AS A SCIENTIST, that it is a problem we 
can do something about. That turns a scientific investigation into a popularity 
contest. I don't want to be one the 97% that Peter Mueller is talking about in

Can’t help you with this, however, I have a couple of PDB deposits that I did 
not publish on and if somebody took them and used my coordinates that’s fine as 
long as they cite the DOI affiliated with the deposition.

Now the question for you, were A and B collaborating on this? If so then 
there’s a different problem and indeed misconduct or at least not good practice 
by B.

Communication is a skill, that some people definitely need to learn.

complain related to the journal publication author issue, with the prerequisite 
journal C did not have the authority on authorship dispute. Then A has e-mailed

In this situation, can A have the journal  authorship  dispute settled by a

that have authority to adjudicate on such matters, as investigation and 
adjudication on authorship claims falls outside the remit of journal editors.

Hi Chandra,

If I remember correctly, the SSRL beam lines 12-2 and 14-1  allow kappa offset 
plus you can swing out the detector.
You might have to come up with a special collection strategy, that you collect 
in resolution bins to avoid overlaps.

World Scientists’ Warning of a Climate Emergency (Condensed Version)
William J. Ripple, Christopher Wolf, Thomas M. Newsome,  scientist 
signatories from xxx countries
We scientists have a moral obligation to clearly warn humanity of any great 
existential threat. In this paper, we present a suite of graphical vital signs 
of climate change over the last 40 years. Results show greenhouse gas emissions 
are still rising, with increasingly damaging effects. With few exceptions, we 
are largely failing to address this predicament. The climate crisis has arrived 
and is accelerating faster than many scientists expected. It is more severe 
than anticipated, threatening natural ecosystems and the fate of humanity. We 
suggest six critical and interrelated steps that governments and the rest of 
humanity can take to lessen the worst effects of climate change, covering 1) 
Energy, 2) Short-lived pollutants, 3) Nature, 4) Food, 5) Economy, and 6) 
Population. Mitigating and adapting to climate change entails transformations 
in the ways we govern, manage, feed, and fulfill material and energy 
requirements. We are encouraged by a recent global surge of concern. 
Governmental bodies are making climate emergency declarations. The Pope issued 
an encyclical on climate change. Schoolchildren are striking. Ecocide lawsuits 
are proceeding in the courts. Grassroots citizen movements are demanding 
change. As scientists, we urge widespread use of our vital signs and anticipate 
that graphical indicators will better allow policymakers and the public to 
understand the magnitude of this crisis, track progress, and realign priorities 
to alleviate climate change. The good news is that such transformative change, 
with social and ecological justice, promises greater human wellbeing in the 
long-run than business as usual. We believe that prospects will be greatest if 
policy makers and the rest of humanity promptly respond to our warning and 
declaration of a climate emergency, and act to sustain life on planet Earth, 
our only home.

Re: [ccp4bb] [EXTERNAL] Re: [ccp4bb] Better Beamline suggestion!

2019-08-20 Thread colin.n...@diamond.ac.uk
I agree with Ed that focusing on the detector might be better than on the 
crystal. An alternative is to reduce the beam divergence which might be easier 
on some beamlines. 

The idea is to ensure the instrument parameters (e.g. beam size, beam 
divergence, detector distance) and data collection parameters (e.g. rotation 
increments) do not degrade the diffraction pattern. This should ensure all 
spots which are intrinsically separated are properly resolved. I don't really 
see the need for a multi circle goniometer if this is done. If the spots are 
naturally smeared due to crystal imperfections then they overlap anyway. In 
this case, as Ed says, one has to ensure the profiles are adequately sampled so 
that any deconvolution procedure has a chance of succeeding.

help much in these situations. If an average spot is 10 or more pixels wide 
then the profile is defined pretty well. But if the spots overlap, they still 
overlap with higher pixel density. It may make profile fitting more accurate, 
allowing more accurate "deconvolution" of the compound spot into its 
components, but it will not improve the overlap. Smaller or better-focused (on 
the detector, not the crystal?) beam, and longer camera length can help.
   It is analogous to chromatography- If two peaks coming off the column 
overlap, collecting smaller fractions will not help to resolve them. It may 
allow a better-informed decision on the cut-off points when you pool the 
fractions, but it won't separate the overlap.
   On the other hand a multi-circle goniometer is very useful. I remember in 
one of our last trips at SSRL (2007-8?) we used a (Huber 4-circle?) and it was 
very easy to have the long axis in the plane of the image throughout the 
rotation.  In the absence of such you can resort to carefully bending the loop 
or bending the pin (Jim Holton made a nifty device for bending the pin) while 
keeping the xtal bathed in the cold stream.

  Hello,
  I transmit this initiative for those who feel that there is
  also life outside reciprocal space and and not only scientist
  in specialist disciplines have a responsibility in real space.
  
  The graphs in the paper mentioned below are sufficiently
  explicit to understand that there is a big problem.
  Best wishes

  Dear Colleague,
We are inviting you and all scientists to sign our new in-press
BioScience  paper "World Scientists' Warning of a
  Climate Emergency" which we want to present to world
leaders.

The article is short and can be read in fewer than eight
minutes. Just go to  http://scientistswarning.forestry.oregonstate.edu/
to read and sign the paper (you can also read a condensed
version of the article below).

Please forward this email to other scientists within your
network or use social media as suggested below. 
    
Thanks, Bill

Scientists’ Warning of a Climate Emergency (Condensed

  Version) 
   William J. Ripple, Christopher
  Wolf, Thomas M. Newsome,  scientist signatories from xxx
  countries 
  We

  scientists have a moral obligation to clearly warn humanity of
  any great existential threat. In this paper, we present a
  suite of graphical vital signs of climate change over the last
  40 years. Results show greenhouse gas emissions are still
  rising, with increasingly damaging effects. With few
  exceptions, we are largely failing to address this
  predicament. The climate crisis has arrived and is
  accelerating faster than many scientists expected. It is more
  severe than anticipated, threatening natural ecosystems and
  the fate of humanity. We suggest six critical and interrelated
  steps that governments and the rest of humanity can take to
  lessen the worst effects of climate change, covering 1)
  Energy, 2) Short-lived pollutants, 3) Nature, 4) Food, 5)
  Economy, and 6) Population. Mitigating and adapting to climate
  change entails transformations in the ways we govern, manage,
  feed, and fulfill material and energy requirements. We are
  encouraged by a recent global surge of concern. Governmental
  bodies are making climate emergency declarations. The Pope
  issued an encyclical on climate change. Schoolchildren are
  striking. Ecocide lawsuits are proceeding in the courts.
  Grassroots citizen movements are demanding change. As
  scientists, we urge widespread use of our vital signs and
  anticipate that graphical indicators will better allow
  policymakers and the public to understand the magnitude of
  this crisis, track progress, and realign priorities to
  alleviate climate change. The good news is that such
  transformative change, with social and ecological justice,
  promises greater human wellbeing in the long-run than business
  as usual. We believe that prospects will be greatest if policy
  makers and the rest of humanity promptly respond to our
  warning and declaration of a climate emergency, and act to
  sustain life on planet Earth, our only home.

Re: [ccp4bb] Better Beamline suggestion!

2019-08-20 Thread Wim Burmeister

  
  
Hello,
the problem can rather be due to mechanical deformations of the
crystal upon mounting and freezing (bent needle, for example). If
the crystals are needle shaped, aligning the long axis with the
spindle axis and using a beamline with a very small beamsize
"microfocus" and a helical scan in order to expose a sufficient
volume will help.
Best

  Dear All
  

  




We recently collected a data set at
  APS, Chicago with unit
  cell dimensions of 68.4; 68.4 and 991.6 A. Our diffraction
  data extends to 3A
  with the APS set up, however, the long axis has been
  problematic, resulting in
  streaking of the diffraction data and requires a very
  specific orientation of
  the crystal for usable diffraction. Can anyone recommend
  beamlines that can
  give us higher resolution, or a source with a better
  goniometer allowing for
  more angle manipulation after looping?
Thank a lot
