Minimum Energy Catastrophic Disruptions
Dramatic alteration of an asteroid’s morphology need not involve high energy impacts between bodies. Simple sunlight shining on an asteroid can, through the YORP effect, cause it to undergo dramatic reconfigurations, fission into a binary asteroid or, in some cases, even undergo a catastrophic disruption with the asteroid losing up to 20% of its initial mass. The YORP effect has recently been d...
متن کاملCollaborative Irrationality, Akrasia, and Groupthink: Social Disruptions of Emotion Regulation
The present paper proposes an integrative account of social forms of practical irrationality and corresponding disruptions of individual and group-level emotion regulation (ER). I will especially focus on disruptions in ER by means of collaborative agential and doxastic akrasia. I begin by distinguishing mutual, communal and collaborative forms of akrasia. Such a taxonomy seems all the more nee...
متن کاملNuclear travel costs energy
n page 765, Ohzeki et al. present evidence for sequence specificity in assembling chromatin at mammalian centromeres. The sequence requirements imply that construction of centromeric chromatin is more than an epigenetic process. O Centromeric chromatin assembles at AT-rich repeats called ␣ satellite sequences, or alphoids. Type I alphoids contain boxes for the binding of CENP-B, one of several ...
متن کاملWood energy: predicting costs.
1389 C R E D IT : B E R N D T H IS S E N /D P A /C O R B IS Wood Energy: Predicting Costs THE POLICY FORUM “WOOD ENERGY IN America” (D. deB. Richter Jr. et al., 13 March, p. 1432) was a much-needed and long-overdue contribution to energy discussions. However, fossil fuels are not four times more expensive than wood per unit energy. Rather, most fossil fuels are still less expensive than wood in...
متن کاملConduction velocity costs energy
Hodgkin and Adrian’s 1975 hypothesis that the squid axon is optimized for maximum conduction velocity is flawed by (i) the inaccurate value of its prediction for channel density, and (ii) the prohibitive energetic expense entailed by their prediction. Here we investigate the metabolic cost of conduction velocity. By manipulating ion channel density or by manipulating the Nernst battery voltages...
