> For the general factor of neuroticism we identified 1,436 SNPs that were genome wide significant and formed 11 independent loci. [...] Again, these findings were comparable to those from the original study by Smith et al.
> We include them here in order to compare them with the first GWASs of neuroticism factors, which we report next. Four SNPs, all on chromosome 12, were genome-wide significant for the worry/vulnerability phenotype. These SNPs were located in one locus, spanning 219kb. This region contains the gene PPFIA2, which is known to be part of the postsynaptic density in humans [14,15].
And further
> The largest difference in the pattern of enrichment found was identified when examining which tissues showed enrichment. For each of the three neuroticism phenotypes, significant enrichment was found for the tissues of the central nervous system (general factor fold enrichment = 2.76, P = 1.35 × 10−4, anxiety/tension fold enrichment = 3.13, P = 1.90 × 10−4, worry/vulnerability fold enrichment = 3.57, P = 2.79 × 10−4);
> however, for the anxiety/tension factor significant enrichment was also found for the adrenal/pancreas (fold enrichment = 4.57, P = 6.52 × 10−4), cardiovascular (fold enrichment = 3.76, P = 0.004), and skeletal/muscle tissues
They actually had data quantifying the nervous tissue. Wow!
> The genetic variants associated with an increase in the general factor of neuroticism were also associated with a genetic risk for a lower household income (rg = -0.39, P = 2.67 × 10−16), and living in an area with a higher level of social deprivation (rg = 0.24, P = 6.95 × 10−5). However, both the anxiety/tension, and the worry/vulnerability factors showed significant genetic correlations in the opposite directions to the general factor of neuroticism for both household income (anxiety/tension rg = 0.25, P = 7.64 × 10−4, worry/vulnerability rg = 0.24, P = 3.57 × 10−4), and living in an area with a higher level of social deprivation (anxiety/tension rg = -0.31, P = 3.87 × 10−5, worry/vulnerability rg = -0.31, P = 5.02 × 10−5).
Amazing, but association is not cause. I can imagine living in a terrible neighbourhood can leave a person, well, terrified, not to say neurotic. One question of an older test they used was removed from the revised test ("do you lock the door at night"), because it didn't fit their P values. Whatever that means, the test seems like a very rough measure to arrive at any statement at all.
And the fact that two traits are inversely related means to me without giving it further due thought, that headline is largely misleading.

It is just chaotic is all I could infer from a first look. I mean English can be pretty messy already and maybe a specific Chinese dialect will be more regular than the bigger picture of the whole language. It's not that your coeds were being cheap, perhaps, it could just be disappointment for something as basic to cost anything at all, and relieve that it's not their personal shortcoming, but just an externalized advantage. You seem to say not even $20 was low enough, have I got that right at least?

What else do you need? A hypergraph of word-vertexes and relation-edges animated in webgl, layered by categories and streamed from an elastic back end? That's your brain.

Also, "the" is used to mark abstract terms, e.g. "I go on monday", but "I go on the next monday" (or just next monday).
Does that show why people care about the articles?
One explanation I found for myself why this is a problem is Normal Forms. A DB table can only have one primary key (definite). All else is secondary, n-ary or arbit-ary. The spoken language should be normalizing, too. Spoken lang... it doesn't make a difference in practice though, noone cares to be precise.

So I had the idea that smaller black holes are at the center of the sun, the earth and so on, being the principle source of gravity and the "movement" that we see is just us falling into different black holes at the same time, which are also falling into each other. So micro black holes must be at the center of massive particles too. The world line of a photon on the other hand is just the intersection of two event horizons as they grow, so you get a wave model. And that's why you have entanglement: circles have two intersections, so if your model is two dimensional, you get two entanglements. But you can have vastly more complicated geometries and thus assembles of entangled particles.
I don't know the "standard model" well enough to take the analogy any further, not to mention string theory and all that jazz.

So, if you don't sense anything, you don't sense time dilation either?
This is slightly more complicated. First of all, you haven't given a frame of reference. If you claim someone were moving at 0.99c then you have already set the frame of reference. And they would have to gain near infinite mass and would die. You seem to assume a restricted frame of reference though, inside the spaceship. So, a point of reference inside the spaceship would see light moving with c inside the spaceship. And would assume his own point of reference as the origin of the inertial frame of reference. So baring any outside measurement, how do you know the spaceship is moving with 0.99c and in which frame of reference?

I think you meant to say ether.
shullbitt0r | 8 years ago | on: Eldar Black Holes
The answer is kinda easy if I can make up my own intrinsic definition. The mass is the mass of the stuff around the black hole. A black hole is a singular point, it can't have mass, don't be silly.
