The stability of orbit of a planet in the field of binary stars

open access: yesPhysical Sciences and Technology, 2021
In the paper, we consider the motion of a planet in the field of the binary stars in the theory of generalrelativity (GR), when all bodies have their own rotation. We consider that the third body moves in the planof massive two bodies.

Exploring the Influence of Oblateness on Asymptotic Orbits in the Hill Three-Body Problem

open access: yesAppliedMath
We examine the modified Hill three-body problem by incorporating the oblateness of the primary body and focus on its asymptotic orbits. Specifically, we analyze and characterize homoclinic and heteroclinic connections associated with the collinear ...

Extension of low-thrust propulsion to the autonomous coplanar circular restricted four body problem with application to future Trojan Asteroid missions [PDF]

open access: yes, 2010
An Autonomous Coplanar Circular Restricted Four Body Problem (CRFBP) is considered, where the massless body is a low-thrust spacecraft. 'Natural' and 'artificial' (i.e.

A Note on the Existence of a Smale Horseshoe in the Planar Circular Restricted Three-Body Problem

open access: yesAbstract and Applied Analysis, 2015
It has been proved that, in the classical planar circular restricted three-body problem, the degenerate saddle point processes transverse homoclinic orbits.

Constant-Power Engines in Flights to L4 point of the Earth-Moon System [PDF]

open access: yesINCAS Bulletin, 2012
The transfer is studied in the context of the classical Circular Restricted Three-Body Problem. The initial state is on a geosinchronous orbit and the terminal state is the L4 triangular Lagrangian point.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Triangular Equilibria in R3BP under the Consideration of Yukawa Correction to Newtonian Potential

open access: yesJournal of Applied Mathematics, 2022
We study the triangular equilibrium points in the framework of Yukawa correction to Newtonian potential in the circular restricted three-body problem.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Influenza Vaccination Responses in Disabled Stroke Patients: A Single‐Center Prospective Observational Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to investigate the immunological response to influenza vaccination, the incidence and severity of influenza infection, and the side effects of the vaccination in patients with ischemic stroke. Methods This prospective observational study was conducted between 2023 and 2024 at Ramathibodi Hospital.

Stability and bifurcation analyses for exterior resonant families in Earth-Moon system

open access: yesResults in Physics, 2021
In this work, stability and bifurcation analyses for exterior resonant orbit families have been investigated for a test spacecraft around Earth-Moon system. The initial states are obtained for certain resonance ratio orbits in the two-body problem.
