Abstract We present asevolution, a cosmological N -body code developed based on gevolution, which consistently solves for the (a)symmetron scalar field and metric potentials within weak-field approximation. In is dynamic can form non-linear structures. A cubic term added in symmetron potential to make symmetry-broken vacuum expectation values different, motivated by observational tensions late-...
Given a learning sample, we focus on the hardness of finding monomials having low error, inside the interval bounded below by the smallest error achieved by a monomial (the best rule), and bounded above by the error of the default class (the poorest rule). It is well-known that when its lower bound is zero, it is an easy task to find, in linear time, a monomial with zero error. What we prove is...
Excessive axial tension is very likely involved in the aetiology of tendon lesions, and the most appropriate indicator of tendon stress state is the true stress, the ratio of instantaneous load to instantaneous cross-sectional area (CSA). Difficulties to measure tendon CSA during tension often led to approximate true stress by assuming that CSA is constant during loading (i.e. by the engineerin...
