We present a general method for the analysis of the gaits used by a six-legged robot independently of the mechanism used to generate the gait. The gait state of the robot is de ned as a function of the last executed steps and several classes of gait states as well as the transitions between them are identi ed. As an example, we apply our method to the well-know wave gaits (the most e cient and ...

Predictions of emergent phenomena, appearing on the macroscopic layer a complex system, can fail if they are made by microscopic model. This study demonstrates and analyses this claim well-known Conway’s Game Life. Straightforward mean-field models easily capable predicting such properties after have been fitted to simulation data in an after-the-fact way. Thus, these predictions macro-to-macro...

To understand spacetime dynamics in the canonical tensor model of quantum gravity for positive cosmological constant case, we analytically and numerically study phase profile its exact wave function a coordinate representation, instead momentum representation analyzed so far. A saddle point analysis shows that Lie group symmetric spacetimes are strongly favored due to abundance continuously exi...

Abstract We present the first ab initio simulation of a radiation-mediated shock emerging at photosphere relativistic outflow. The is performed using our code radshock that follows fluid dynamics coupled to time-dependent radiative transfer, calculated with Monte-Carlo method. use examine blast wave from neutron star merger GW170817. It was previously proposed ejected dark, relativistically exp...

Spin wave, the collective excitation of magnetic order, is one fundamental angular momentum carriers in systems. Understanding spin wave propagation textures lies heart developing pure information processing schemes. Here we show that across a chiral domain wall follows simple geometric trajectories, similar to optics. And behaviors are qualitatively different normally magnetized film and tange...

in Circulation, 1 extends the arrhythmia prognostic testing application of electric alternans from the ventricular to the atrial cardiac repolarization. The authors measured in the setting of an electro-physiology study of a total of 33 patients with a history of paroxysmal, or persistent atrial fibrillation (AF), or no such history, the action potential duration (APD) in the left atrium (in al...

The effects of acute nutritional change on endocrine and ovarian characteristics were studied in cyclic (intact; n = 20) and long-term ovariectomized (ovx; n = 18) heifers being fed 1.2 x maintenance (1.2M). On d 7 of an 8-d progesterone and estradiol treatment, intact and ovx heifers were randomly allocated to diets providing .4, 1.2, or 2.0M until emergence of the second follicular wave after...

time-of-flight diffraction method (tofd) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. although tofd can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. in this paper, a new tofd method for evaluating horizontal planar defects is presented. the finite...

This work was carried out with a number of colleagues, chief among whom Yves Couder, Matthieu Labousse, Marc Miskin & Stéphane Perrard. We have recently discovered a macroscopic object composed of a material particle dynamically coupled to a wave packet. The particle is a droplet bouncing on the surface of a vertically vibrated liquid bath; its pilot-wave is the result of the superposition of t...
