General planetary vehicle and industrial space necklace “Orbit” as an alternative to rocket near space exploration

open access: yesRUDN Journal of Engineering Research, 2021
The paper presents an alternative to rockets general planetary vehicle (GPV) and industrial space necklace Orbit (ISN Orbit), which are a single complex necessary for the non-rocket near space exploration.

Development of the structure, survey and design of the equatorial overpass of the General Planetary Vehicle

open access: yesRUDN Journal of Engineering Research, 2021
The runway for the General Planetary Vehicle is a unique in scale and complexity infrastructural construction - an overpass with a length of 40 000 km, covering the planet along the equator and combined with a string-rail transport of the second level ...

A new gauge-invariant double copy for heavy-mass effective theory

open access: yesJournal of High Energy Physics, 2021
We propose a new form of the colour-kinematics/double-copy duality for heavy-mass effective field theories, which we apply to construct compact expressions for tree amplitudes with heavy matter particles in Yang-Mills and in gravity to leading order in ...

String Shooter’s overall shape in ambient air

open access: yesEmergent Scientist, 2020
In this article, we study the behaviour of a looped string launched in ambient air using motorised wheels. We show that the loop, once it reaches its stationary state, is either in the pulley or the air-lifted state.

Method for analysis of planar motion of system with rigid and extremely flexible components via analogy with contact problem of rigid bodies

open access: yesMechanical Engineering Journal, 2021
Recent years have witnessed attempts to employ a system with rigid and extremely flexible components (SREF), usually consisting of strings, membranes, and so on, to realize huge structures for spacecraft in orbit.

S-duality and the double copy

open access: yesJournal of High Energy Physics, 2020
The double copy formalism provides an intriguing connection between gauge theories and gravity. It was first demonstrated in the perturbative context of scattering amplitudes but recently the formalism has been applied to exact classical solutions in ...

The influence of providing perches and string on activity levels, fearfulness and leg health in commercial broiler chickens

open access: yesAnimal, 2015
The aim of this study was to assess the effect of providing environmental enrichment in the form of perches and string on the behaviour and welfare of commercial broiler chickens.
