Managing the breakup
C ompared with the complex choreography required to sort chromosomes during mitosis, cytokinesis might seem fairly simple. But ensuring that the contractile ring of actin and myosin pinches off daughter cells also takes some fancy footwork. Two independent groups (1, 2) offer fresh details about how cells cue cytokinesis at the right time and place. Cytokinesis can’t begin until the chromosomes...
متن کامل2 dimensional finite stochastic breakup model of biomass particle breakup.
Due to the high content of cellulose, hemicellulose and lignin, the anisotropy of biomass particle in spatial structure induces the difference of mechanical properties in different directions. In this paper, based on the finite stochastic breakup model and anisotropy of biomass particles, 2-dimensional finite stochastic breakup model (2D-FSBM) of biomass particle was proposed, and the breakup p...
متن کاملPeripherality of breakup reactions
Breakup calculations of loosely bound nuclei (B and Be) are performed with two different descriptions of the projectile. The descriptions differ strongly in the interior of the wave function, but exhibit identical asymptotic properties (ANC, and phase shifts). Calculations are performed for both nuclei at intermediate (40–70 MeV/nucleon) and low (26 MeV) energies with heavy and light targets. N...
متن کاملLi direct breakup lifetimes
α-d coincidence data were studied for the Li + Co reaction at Elab = 29.6 MeV. By using a kinematic analysis, it was possible to identify which process, leading to the same final state, has the major contribution for each of the selected angular regions. Contributions of the Li sequential and direct breakup to the incomplete fusion/transfer process were discussed by considering the lifetimes ob...
متن کاملCoulomb breakup problem.
We formulate scattering theory in the framework of a surface-integral approach utilizing analytically known asymptotic forms of the three-body wave functions. This formulation is valid for both short-range and Coulombic potentials. The post and prior forms of the breakup amplitude are derived without any reference to renormalization procedures.
