Put yer nerd goggles on

It's early enough in the morning, I'm betting very few of you are too drunk to understand this, unless you're still recovering from last night.

The survival probability of immobile targets annihilated by a population of random walkers on inhomogeneous discrete structures, such as disordered solids, glasses, fractals, polymer networks, and gels, is analytically investigated. It is shown that, while it cannot in general be related to the number of distinct visited points as in the case of homogeneous lattices, in the case of bounded coordination numbers its asymptotic behavior at large times can still be expressed in terms of the spectral dimension d-tilde and its exact analytical expression is given. The results show that the asymptotic survival probability is site-independent of recurrent structures (d-tilde <=2), while on transient structures (d-tilde >2) it can strongly depend on the target position, and such dependence is explicitly calculated.
If you are too drunk, here's a simpler explanation.

You had me at "annihilated".

Fucking Zombies

2 I just finished reading World War Z.  And now I can't help but scope out buildings for their defensive value against potential zombie attack.  Cause I'm in South Carolina, not much chance of a hard freeze down here giving me a season to set up good defenses.

3 This is stupid. It assumes zombie movements are completely random, which is not the case. A zombie, upon locating a source of living flesh, will attempt to get to it relentlessly. Zombies also have a tendency to follow one-another. So, once you have a zombie that spots you, you will end up with a metric shit-ton of zombies trying to eat your brains.

The key is to kill any zombies that have spotted you. If that is not feasible, the next best solution is to get the fuck out of dodge and set up a compound with the other survivors away from any of the old population centers. This minimizes the risk of random zombie encounters.

Agreed: distance yourself from population centers. Establish clear lines of fire for all approaches. Stockpile lots of ammo.

I favor an easily defensible redoubt based in the southwest; preferably Canyon de Chelly or somewhere similar.

5 Single best piece of ZA survival advice - edge weapons don't need reloading.

Yes, but Alex, the major disadvantage of edge weapons is that it allows - no, requires - the attacker to be within biting distance before you can off it.  It also requires no defensive bulwarks be between you and the zombie hoard.

I feel very confident in saying that edge weapons should be a last resort in any real zombie attack.  I think flame throwers would be my first choice, because I just can't get over how fucking awesome it would be to see the undead fuckers burning like crispy critters.

7 Exactly. Swords are a last resort.
Unfortunately, I'm going to have to spend gun money on a sword, you need a last resort item and my 1911 only has a 7 round mag.

Obama and Senate <a href="http://www.trustsreligionjeans.com/">True Religion Brand Jeans</a> leaders plan to try to pass elements of the measure, and the president used his weekly Internet and radio address Saturday to urge Republicans to support his economic proposals — or else explain to their constituents why they didn't.

Rousseff didn't stop with True Religion Brand Jeans chief of staff. In quick succession, she let go of three other ministers publicly accused of everything from receiving kickbacks to charging the government for staying at a love motel. Meanwhile, public outrage had turned into regular street protests.
