I could not agree with your comment more. I've been using elementary since its original beta and absolutely love it. It not only looks great, but it is laid out to be usable. My core i5 dell with elementary luna is my go-to coding machine. This new release should make it even better. Having used quite a few distros over the last 12+ years (RHL, gentoo, mandrake, Suse, ubuntu, fedora, debian, cent, *BSD), I can say this is by far the best thought-out release I have ever used. Seriously, give it a try.
Re: "looks like OSX so who cares" comments:
The only feature this distro really shares with OSX is the dock, which BTW, can literally be installed on an OS now. The animations are crisp, memory footprint is light, and it has enough unique usability feature to make it transcend the "OSX-clone" status.
The big leap hear was observing the interaction of *only* 2 spins, not the physics. Just to be clear, this study has confirmed that standard spin physics work on the atomic scale. Confirming these basic laws for a system of two atoms is important because it can expose holes in our understanding of physics that came from only observing an ensemble of spins and not single spin states.
Just a few notes:
Derivations of quantum mechanical interactions come from basic formulas of classical mechanics, but strictly speak the physics in this paper are *NOT* Newtonian. They are talking about the energy of the interaction, not the force. For two electron dipoles interacting in space, the basic formulation come from F = (q1*q2)/(d^4). Because energy is force x distance: E = F*d = (q1*q2)/d^-3. This observation *is* expected since these physics govern basic magnetic resonance principles. The leap here comes from the fact that magnetic resonance experiments deal with LOTS of atoms, not two.
The previous was a troll comment? I was just sharing an opinion civilly and suggesting that people take some (not all) responsibility for their lack of privacy. The intention was not to incite hatred, just to engage in debate. Can I get a meta-moderator? geeze
Yeah its underhanded and shitty, but if we keep playing by the same rules, awe shouldn’t be surprised when nations life china surpass us. I’m not saying I agree with their practices at all, but this is a new reality that needs to be accepted and overcome.
Dishonesty has become a real problem in science. Some recent cases (Judy Mikovits, Luk Van Parijs, and Dipak K. Das (aka the red-wine researcher)) reveal some serious misconduct from high profile researchers. Certainly, part of this is due to the increased pressure on scientific researchers. The other part of this is generational. Cheating and misconduct are certainly more prevalent.in younger generations (or perhaps its always been this way and they are just not quite as clever).
Well, if these games can get younger people interested in the concepts of programming, I'm all for it. I'm not a fan of most online games, but I have to say this is really cool. I think more games should provide an environment to explore programming (optionally of course)
I'd have to agree with you. People need to take some (most) of the blame for this. No one forced your to join Facebook, twitter, flickr, etc. and you had to know that these were not services being sold with the guise of anonymity. Yes companies are using tracking cookies and algorithmic hocus-pocus to profile your habits, but these can be circumvented with little effort. If you want to share everything, fine. But your info is now essentially public.
It just seems like they have set up new ground rules by which an army of lawyers will translate into a high-cost-of-entry market (jn a market with an already bloated cost of entry). I would not hold my breath in hoping that corporations will change their practices...
I think you hit the nail on the head. Diagnostics have become a black hole in the budgets of health care providers and they are catching on. It is sad that lower priority, perhaps unnecessary cases are put in the same cue as higher priority cases (triage is not always perfect). Informing the uninformed is always a challenge indeed. I'll be the first to admit that the people in my field develop more techniques than there is a need. That being said, I don’t think enough informed people are critically evaluating the existing options through the lens of improving care.
Yep, this is definitely the case in medicine. Researchers in my field tend be be fine with adopting new techniques, but the translation of the science into treatment is the real hurdle. The gate-keepers tend to take a more conservative approach, and seemingly reject new-things de-facto if there's an older, similar technique already in use (even if the new one is a quantum leap forward and offers numerous other advantages). Their argument on one hand is to prevent unnecessary complexity in treatment, and on the other its political (i.e. keeping cost of treatment down). Perhaps the answer is to get some energetic, young policy makers in the FDA and insurance companies that will start seeing the merit newer techniques. I not even touching on the cynical side of the issue (i.e. who are the campaign contributors and former employers of the regulators)...
I had a similar problem. I had let a friend borrow an external for a backup and it came back write protected! He was using windows, I mac and linux, and could not figure out why/ how this happened. I was at capacity on that drive as well as two others and needed space bad (needed to back up a laptop before installing new os). A few other friends came to my rescue and allowed me to borrow some of their drives until i could find a more permanent solution. The suggestion to build a raid box is a good one.It will allow you to build up your storage capacity over time. My advice is to use multiple methods: back up locally AND send your most essential data to the cloud via an encrypted service (this will protect against a fire, theft, etc. Plus its handy to have access to your files from any computer). I like wuala personally, but spideroak is also very nice solution as well. There are lots of good, secure solutions now that are relatively affordable
Haha, very true. My comment was clearly meant as a joke... I love to poke fun at ms, but I have to say I've been impressed with my experience with win7. Here's to hoping 8 is even better
Finally another poster who knows how this type of spectroscopy works! In the early days of MRI, they tried probing different nuclei such as P31 and C13, but it never really got a lot of traction. The bottom line is that physicians don't know and frankly don't want to know much about the spectroscopy (there are exceptions, but its not common). For example, scientists have been able to non-invasively map all white matter connections in the brain (by DTI of Q-ball imaging) for the past 20 years, but this has never made its way into the clinic unfortunately. BOLD imaging is just starting to gain traction clinically, but its very slow. As a spectroscopist, I have to accept the reality that most methods people in my field develop will never leave the laboratory... I think people who develop any diagnostic test share this frustration.
The issue with using an insensitive nuclei for imaging is that they are not abundant at all. C13 and N15 are not naturally common in biological systems, and are not ubiquitous to all tissues. These nuclei are used for special cases in medicine (isotopically labeled tracers), but in generally are not used.
Also, resistive magnets are sometimes used in the "open-scan" MRIs. They take a ton of power to run and are generally at lower fields (higher field = more heat). Like you said, these magnets tend to be as expensive as their super-conducting counterparts because they have to have PERFECT magnetic fields for imaging. We have a 36ish Tesla restive magnet at my lab (not something I use) that practically requires its own sub-station to run. The energy required to cool the water that flows through the cools is another issue altogether!
Rodent are easier to study than humans for a lot of reasons (fewer ethical issues, you can dissect them when you're done to confirm what you are seeing, lots of animal disease models exist, etc). Almost all MRI techniques are developed on animal models long before they reach a human. Because of this, there's a huge demand for animal-sized spectrometers. If someone can get a grant approved for it, companies will usually line up to be first to build the new instrument. Bragging rights goes a long way in my field
The only difference between an NMR experiment and an MRI experiment is the use of imaging coils, not the type of magnet. Almost ALL NMRs used today are super-conducting, while there are still plenty of resistive MRIs (many of the "open-scan" types are resistive). If you can make a bore hole large enough, these same imaging coils can be used in modern NMR spectrometers to turn them into an MRI (not for anything large though). The brains of zebra finches are commonly studied (ex-vivo) in high field spectrometers because they are really small and have complex white-matter connections that are of interest to neuroscientists. The pulsed-field-gradients that make the MRI experiment possible were originally developed for NMR experiments and are still common today. Also MRI is a form of spectroscopy. On the very basic level, the image is produced by a deconvolution of the observed nuclear-spin anisotropies (there are many flavors of this) into an image.
