MEGASIM: Distribution and Detection of Earth Trojan Asteroids
The Astrophysical JournalUsing N -body simulation results from the MEGASIM data set, we present spatial distributions of Earth Trojan Asteroids and assess the detectability of the population in current and next-generation ground-based astronomical surveys.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective People with epilepsy (PWE) may experience cognitive deficits but fail to undergo formal evaluation. This study compares cognitive status between PWE and healthy controls in the West African Republic of Guinea. Methods A cross‐sectional, case–control study was conducted in sequential recruitment phases (July 2024–July 2025) at Ignace ...

One-Dimensional Relativistic Self-Gravitating Systems
EntropyOne of the oldest problems in physics is that of calculating the motion of N particles under a specified mutual force: the N-body problem. Much is known about this problem if the specified force is non-relativistic gravity, and considerable progress has ...

Photodisintegration of 9Be and the importance of the unbound 1/2+ state
EPJ Web of Conferences, 2016 The photodisintegration cross section of the 9Be(1/2+) state is investigated in a framework of the α + α + n three-body model. The 1/2+ state of 9Be locates just above the three-body threshold, and the s-wave neutron property of this state is a long ...

Applying an Ethical Lens to the Treatment of People With Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT The practice of neurology requires an understanding of clinical ethics for decision‐making. In multiple sclerosis (MS) care, there are a wide range of ethical considerations that may arise. These involve shared decision‐making around selection of a disease‐modifying therapy (DMT), risks and benefits of well‐studied medications in comparison to

N-body problem in $R^n$: Necessary conditions for a constant configuration measure
Electronic Journal of Differential Equations, 2008 A formulation of the N-body problem is presented in which $m_{i}$ and $r_{i}in mathbb{R}^d$ are the mass and the position vector of the i-th body, $ x=(sqrt{m_{1}}r_{1},dots ,sqrt{m_{N}}r_{N})in mathbb{R}^n$ and $ n=dN$ ($d=1,2,3$).

Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

On the stability of the homographic polygon configuration in the many-body problem
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2004 In this paper the stability of a new class of exact symmetrical solutions in the Newtonian gravitational (n + 1) -body problem is studied. This class of solution follows from a suitable geometric distribution of the (n+1) -bodies, and initial ...

Solving one-body ensemble N-representability problems with spin [PDF]
QuantumThe Pauli exclusion principle is fundamental to understanding electronic quantum systems. It namely constrains the expected occupancies $n_i$ of orbitals $\varphi_i$ according to $0 \leq n_i \leq 2$. In this work, we first refine the underlying one-body $
