Calculating Masses of Pentaquarks Composed of Baryons and Mesons [PDF]

open access: yesAdvances in High Energy Physics, 2016
We consider an exotic baryon (pentaquark) as a bound state of two-body systems composed of a baryon (nucleon) and a meson. We used a baryon-meson picture to reduce a complicated five-body problem to simple two-body problems.

Addressing general measurements in quantum Monte Carlo [PDF]

open access: yesNature Communications
Quantum Monte Carlo is one of the most promising approaches for dealing with large-scale quantum many-body systems. It has played an extremely important role in understanding strongly correlated physics. However, two fundamental problems, namely the sign

On the Periodic Orbits of the Perturbed Two- and Three-Body Problems

open access: yesGalaxies, 2023
In this work, a perturbed system of the restricted three-body problem is derived when the perturbation forces are conservative alongside the corresponding mean motion of two primaries bodies.

Scattering From Chiral Cylinders of Arbitrary Cross-Sections Above a Ground Plane

open access: yesIEEE Access, 2021
The main purpose of this work is to solve the problem of electromagnetic scattering from a chiral cylinder of arbitrary cross-section above an infinite perfect electric conducting (PEC) plane.

Comparisons between the circular restricted three-body and bi-circular four body problems for transfers between the two smaller primaries

open access: yesScientific Reports, 2022
Important properties of the dynamics of a spacecraft can be obtained from the Circular Restricted Three Body Problem and the Bi-Circular Bi-planar Four Body Problem. In this work, both systems are compared under the perspective of the costs involved in a

Attitude and Configuration Control of Flexible Multi-Body Spacecraft [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
Multi-body spacecraft attitude and configuration control formulations based on the use of collaborative control theory are considered. The control formulations are based on two-player, nonzero-sum, differential game theory applied using a Nash strategy ...

Risk factors in body image dissatisfaction: gender, maladaptive perfectionism, and psychological wellbeing

open access: yesHeliyon, 2022
Discontent with one’s appearance (body image dissatisfaction) has become a global phenomenon, associated with the development of extreme behaviours in order to correct perceived body image problems.

Body as the “Locus of Self”: The Subjective Experience of Eating Problems

open access: yesPsikoloji Çalışmaları, 2021
Eating problems arise in relation to problems with eating attitudes and behaviors but is not limited to these contexts. Moreover, eating problems develop when one’s personal integrity is shaken, simultaneously affecting the body and mind by causing ...

A Heideggerian Approach to the Embodied Cognition and Problem of Constitution in the Cognitive Science [PDF]

open access: yesJournal of Philosophical Investigations, 2021
In this article, we discuss how body plays a role in cognition. For this purpose, constitutive and causal approaches in the cognitive science are reviewed.

Quartic Integral in Rigid Body-Gyrostat Dynamics

open access: yesAdvances in Astronomy, 2020
In this work, we investigate the problem of constructing new integrable problems in the dynamics of the rigid body rotating about its fixed point as results of the effect of a combination of potential and gyroscopic forces possessing a common symmetry ...
