<p>If you have a system with equally distributed temperature, and in the center of it is inserted a point source of heat (a point hotter than the rest of the system) after a given amount of time this heat is dispersed through the system in a way that the points closer to the center are hotter than the ones farther from it.</p> <p>What is the function of the distance that describes more precisely the temperature distribution in this system?</p>

<p>I am developing a heat map image generator and I have come to 2 solutions to calculate the intensity in a given point within a distance from the heat source:</p> <p>The first one is similar to wave dispersion:</p> <blockquote> <p>intensity = 1 / math.pow(1 + distance, 2)</p> </blockquote> <p>The second one looks nice on the screen, but I invented it myself</p> <blockquote> <p>intensity = math.pow(2, -distance)</p> </blockquote> <p>I don't know if any of the solutions above are near the real world behavior.</p>

<p>I am trying to do some functional assays on primary smooth muscle cells from young mice. When I say young I mean newborn esophagus or 3 week old aortic smooth muscle. There are not many cells for functional assays so I take them into cell culture for a while until they grow confluent, and then I try to stimulate them with an agonist (carbachol) and visualize contraction under the microscope. The problem appears to be that these cells lose their contractility really fast and I can't see any response to agonist, although smooth muscle actin expression is still quite high (so they are still 'smooth muscle cells'). I culture them in DMEM + 10% FBS on plastic. I read that primary SMCs will rexpress contractility makers if starved for 3 days, but this hasn't helped my situation--maybe this trick is human-specific?</p> <p>Does anyone have any tips on how I can keep these cells contraction-competent in culture?</p>
