An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are uscd as means of control so that the total angular momentum of the multibody system is a constant, assumed to be zero in this paper. The control strategy utilizes the nonintegrability of the exp...

This paper presents a novel theoretical framework to model the evolution of a dynamic portfolio (i.e., a portfolio whose weights vary over time), considering a given investment policy. The framework is based on graph theory and quantum probability. Embedding the dynamics of a portfolio into a graph, each node of the graph representing a plausible portfolio, we provide the probabilities for a dy...

In this paper we prove a recent conjecture [Robnik M and Salasnich L 1997 J. Phys. A: Math. Gen. 3

In modern conditions, the integration of ESG-criteria into investment decisions asset managers is considered as a key factor in sustainable economic development. We examine effectiveness Momentum-ESG strategy based on Responsibility and Openness Index comparison with Momentum strategy, which Moscow Exchange Broad Market Index, since December 2011 to 2020. propose an algorithm for integrating ES...

M q ðxÞ 1⁄4 x T q ðxÞ x T q ðxÞ: (5) Since Jþi is a leading-twist operator, it is clear that such a simple partonic interpretation should exist. However, Ji, Xiong, and Yuan misleadingly interpret Jþi as the transverse angular momentum operator. Indeed, in light-front quantization, the role of time is taken by xþ, so that Jþi is the light-front transverse boost operator. In terms of the more co...

a classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. the model takes into consideration the effect of diffraction outside the capture limit on the rate constants. the theory is used to calculate momentum transfer rate constant for cl- with trans-dichloroethylene and para-difluorobenzene. theoretical results are compared to...

We present a “hierarchical” strategy for phase space generation in order to efficiently map the antenna momentum structures, typically occurring in QCD amplitudes.
