Constraints on the Universal Contact Interaction [PDF]

Physics Letters B, 1997
Forces beyond those of the standard model may manifest themselves at low energies as four-fermion contact interactions. If these new forces are independent of colour and flavour quantum numbers including baryon and lepton number, then all low energy ...

Contact Estimation in Robot Interaction [PDF]

International Journal of Advanced Robotic Systems, 2014
In the paper, safety issues are examined in a scenario in which a robot manipulator and a human perform the same task in the same workspace. During the task execution, the human should be able to physically interact with the robot, and in this case an ...

Contact Interaction of Steam Turbine Inner Casing Elements During Plastic Deformation [PDF]

Journal of Mechanical Engineering, 2021
A structure’s material plasticity influence on the pattern of contact interaction of its elements during operation is studied. The stress-strain state problem for the inner casing of a steam turbine high-pressure cylinder operating at supercritical steam

Modelling and Numerical Solution of the Problem with Unilateral Constraints and Friction under Dynamic Action of the Load

Наука и техника, 2021
Problems with unilateral constraints are not uncommon in the practice of calculating  building construction and structures. Certain difficulties in solving them arise during contact friction, as well as the dynamic action of the load.

On Hermite Functions, Integral Kernels, and Quantum Wires

Mathematics, 2022
In this note, we first evaluate and subsequently achieve a rather accurate approximation of a scalar product, the calculation of which is essential in order to determine the ground state energy in a two-dimensional quantum model.

Development and Validation of a Subject-Specific Coupled Model for Foot and Sports Shoe Complex: A Pilot Computational Study

Bioengineering, 2022
Nowadays, footwear serves an essential role in improving athletic performance and decreasing the risk of unexpected injuries in sports games. Finite element (FE) modeling is a powerful tool to reveal the biomechanical interactions between foot and ...

Of contact interactions and colliders [PDF]

Physical Review D, 2015
The hierarchy of scales which would allow dimension-six contact interactions to parametrise New Physics may not be verified at colliders. Instead, we explore the feasability and usefulness of parametrising the high-energy tail of distributions at the LHC using form factors.

Is the Non-Pointness of the Electron Observable in $e^{+}{e}^{-}$ Annihilation at Center-of-Mass Energies 55–207 GeV?

Physics, 2023
The experimental data from VENUS, TOPAS, OPAL, DELPHI, ALEPH and L3 Collaborations collected from 1989 to 2003 are applied to study the quantum electrodynamics (QED) framework through the direct contact interaction term approach, using the annihilation ...
