Post-Newtonian celestial mechanics in scalar-tensor cosmology [PDF]
, 2016 Applying the recently developed dynamical perturbation formalism on cosmological background to scalar-tensor theory, we provide a solid theoretical basis and a rigorous justification for phenomenological models of orbital dynamics that are currently used

Advances and Trends in Terrain Classification Methods for Off‐Road Perception
Journal of Field Robotics, EarlyView.ABSTRACT Off‐road autonomous vehicles (OAVs) are becoming increasingly popular for navigating challenging environments in agriculture, military, and exploration applications. These vehicles face unique challenges, such as unpredictable terrain, dynamic obstacles, and varying environmental conditions.

Journal of Field Robotics, EarlyView.ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Global regularization method for planar restricted three-body problem [PDF]
Serbian Astronomical Journal, 2015 In this paper, global regularization method for planar restricted three-body problem is purposed by using the transformation z = x+iy = ν cos n(u+iv), where i = √−1, 0 < ν ≤ 1 and n is a positive integer. The method is developed analytically and

Small, EarlyView.This study investigates the impact of MWCNT reinforcement on the compressive strength of lunar regolith composites under varied curing conditions, including ambient with and without cycling and vacuum with cycling. Utilizing experimental methodologies, it identifies significant relationships between MWCNT content, curing protocols, and thermal cycling,

Art as a Channel and Embodiment of Symbolic Interaction Between Migrants and Non‐Migrants
Symbolic Interaction, EarlyView.Many non‐migrant politicians, journalists, and scholars in migrant‐ destination societies often represent migrants with self‐interested objectives and in specific instrumental ways based on stereotypes. Yet research on symbolic interaction reveals migrants are not passive victims.

The Chemical Record, EarlyView.The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...
