EGFR-dependent TOR-independent endocycles support Drosophila gut epithelial regeneration
Following gut epithelial damage, epidermal growth factor receptor/mitogen-activated protein kinase (EGFR/MAPK) signalling triggers Drosophila intestinal stem cells to produce enteroblasts (EBs) and enterocytes (ECs) that regenerate the gut. As EBs differentiate into ECs, they become postmitotic, but undergo extensive growth and DNA endoreplication. Here we report that EGFR/RAS/MAPK signalling i...
متن کاملThe Tor Game
Let M and N be non-zero finitely generated modules over a local (Noetherian) ring (R,m). Assume that TorRi (M,N) = 0 for i >> 0, and let q = qR(M,N) be the largest integer i for which TorRi (M,N) 6= 0. For the case q = 0, Auslander [A, Theorem 1.2] found a useful formula relating the depths of M , N and R. In view of the Auslander-Buchsbaum formula [BH,Thm. 1.3.3] Auslander’s theorem goes as fo...

متن کاملThe Neutron Star Census
The paucity of old isolated accreting neutron stars in ROSAT observations is used to derive a lower limit on the mean velocity of neutron stars at birth. The secular evolution of the population is simulated following the paths of a statistical sample of stars for different values of the initial kick velocity, drawn from an isotropic Gaussian distribution with mean velocity 0 ≤ V ≤ 550 km s −1. ...
متن کاملPrice forecast in the competitive electricity market by support vec - tor
Price forecast is a task challenging and very important in competitive electricity market context. Both market players and regulators concern very much about the price evolution, on one hand, the prediction of the market price is a crucial information for the production arrangement and bidding strategies.
