Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, EarlyView.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

SerDes link co-simulation and passive link optimization design

Dianzi Jishu Yingyong
As the signal transmission rate of the SerDes link increases, the signal integrity (SI) challenge increases further as the channel link passes through PKG and PCB boards, through holes, AC capacitors and connectors.

Double CO WD systems from the WD+He subgiant channel and type Ia supernovae

Open Astronomy, 2016
Recent studies suggested that at least some of the observed SNe Ia originate from the double-degenerate model, which involves the merging of double carbon-oxygen white dwarfs (CO WDs).

Geometric Coplanar Constraints-Aided Autonomous Celestial Navigation for Spacecraft in Deep Space Exploration

IEEE Access, 2019
Autonomous celestial navigation has been exploited for orbit determination of deep space exploration. Geometric constraints in celestial measurement are the inherent attributes in actual comprehensive autonomous celestial navigation physical systems ...

Must Longtermists Wish Us All Dead? A Quadrilemma

Journal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...

Understanding Autistic Young Adults' Perceptions and Experiences of Traumatic and Stressful Events

Journal of Clinical Psychology, Volume 81, Issue 6, Page 445-461, June 2025.
ABSTRACT Objectives The aim of this study was to explore how young autistic adults experience and respond to stressful life events, and the relationship between autistic characteristics and symptoms of stress associated with these events. Methods Using an exploratory sequential mixed‐methods approach, an online qualitative survey was first administered

Ambidextrous light transforms for celestial amplitudes

Journal of High Energy Physics, 2022
Low multiplicity celestial amplitudes of gluons and gravitons tend to be distributional in the celestial coordinates z, z ¯ $$ \overline{z} $$ . We provide a new systematic remedy to this situation by studying celestial amplitudes in a basis of light ...

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

Mass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...
