Perturbing positive feedback gave rise to a sluggish, variable entry and progression through mitosis and uncoupled duration of mitosis from variability in cell cycle length. By combining live cell imaging and computational modeling, we showed that positive feedback is the molecular mechanism underlying the temporal insulation of mitosis. Surprisingly, there is no correlation between cell-cycle length and mitotic duration, suggesting that mitosis is temporally insulated from variability in earlier cell-cycle phases. Quantitative measurements of cell-cycle dynamics in single cells showed that despite variability in G1-, S-, and G2 phases, duration of mitosis is short and remarkably constant. Positive Feedback Keeps Duration of Mitosis Temporally Insulated from Upstream Cell-Cycle Events.Īraujo, Ana Rita Gelens, Lendert Sheriff, Rahuman S M Santos, Silvia D MĬell division is characterized by a sequence of events by which a cell gives rise to two daughter cells.

Before modding Sonic Generations was a cool idea, you'd see a whole lot of people port levels over to GDK instead considering that since its inception it could do both 3D and 2D albeit with a bit of scripting via splines. First started by Xaklse, this engine has grown to have many, many contributors building on this engine for the six years and counting since its release. First released on 2010, February 10, the Sonic Games Development Kit has been a collected code source for anyone in the Sonic fanbase at large to develop their own 3D Sonic the Hedgehog fangame. So, Sonic GDK, starting with a bit of history. I've been looking to make sure and apparently no one except a few people are talking about this in a general thread or status update and considering that GDK is fanmade I felt it belonged here. The risks of sharing information about terrorism Mainstream media outlets are dropping the ball with terrorism coverage Six minutes of raw video was posted by, which, after a warning at the front of the clip, showed video from the gunman’s helmet camera as he drove through the streets on his way to the mosque. On Facebook, it was easy to source pictures, and even a selfie, that the alleged perpetrator had shared on social media before entering the mosque.īut it was not just social media that shared the pictures. Later, it was possible to see that his Twitter account had been suspended. Today, information about the name of the Christchurch gunman, his photograph and his Twitter account, were easy to find. The editor of Le Monde, Jérôme Fenoglio, said:įollowing the attack in Nice, we will no longer publish photographs of the perpetrators of killings, to avoid possible effects of posthumous glorification. Following a spate of killings in France in 20, French mainstream media proprietors decided to adopt a policy of not recycling pictures of atrocities. |
