# behav: walking with turning

<< Normal human locomotion in daily life involves walking with turning, not just straight line walking. (..) the metabolic rate while walking in circles increases with decreasing radius for fixed speed. (..) this increase in energy cost for turning has behavioral implications >>

<< to save energy, (..) humans should walk slower in smaller circles, slow down when path curvature increases when traveling along more complex curves, turn in place around a particular optimal angular speed, and avoid sharp turns but use smooth gentle turns while navigating around obstacles or while needing to turn while walking. >>

# gst: irregular sampling design to address behaviours

<< Animal movement studies have become ubiquitous in animal ecology for the estimation of space use and the analysis of movement behavior. In these studies, animal movement data are primarily collected at regular time intervals. (AA) propose an irregular sampling design that could lead to greater efficiency and information gain in animal movement studies. (The) novel sampling design, called lattice and random intermediate point (LARI), combines samples at regular and random time intervals. >>

<<  in each of the data and simulation examples explored in this paper, LARI sampling results in more accurate and precise parameter estimation and, thus, better prediction of missing data as well.  >>

# gst: a concrete image, chirality by dissipation, 'this effect actually owes its existence to dissipation'

# astro: you might find erratic massive black holes in dwarf galaxies ...

<< The new VLA (Very Large Array) observations revealed that 13 of these galaxies have strong evidence for a massive black hole that is actively consuming surrounding material. (AA) were very surprised to find that, in roughly half of those 13 galaxies, the black hole is not at the center of the galaxy, unlike the case in larger galaxies, >>  Amy Reines.

<< The scientists said this indicates that the galaxies likely have merged with others earlier in their history. This is consistent with computer simulations predicting that roughly half of the massive black holes in dwarf galaxies will be found wandering in the outskirts of their galaxies. >>

<< This work has taught us that we must broaden our searches for massive black holes in dwarf galaxies beyond their centers to get a more complete understanding of the population and learn what mechanisms helped form the first massive black holes in the early Universe, >> Amy Reines.

# gst: apropos of 'large deviations', the instanton, to trace rogue waves

<< Strong evidence is given that the rogue waves observed in the tank are hydrodynamic instantons, that is, saddle point configurations of the action associated with the stochastic model of the wave system. (..) these hydrodynamic instantons are complex spatiotemporal wave field configurations which can be defined using the mathematical framework of large deviation theory and calculated via tailored numerical methods. These results indicate that the instantons describe equally well rogue waves created by simple linear superposition (in weakly nonlinear conditions) or by nonlinear focusing (in strongly nonlinear conditions), paving the way for the development of a unified explanation to rogue wave formation. >>
