Pulsar Signal Adaptive Surrogate Modeling
AerospaceAs the number of spacecraft heading beyond Earth’s orbit increased in recent years, autonomous navigation solutions have become increasingly important. One such solution is pulsar-based navigation.

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions [PDF]
Astrophys.J.701:1161-1174,2009, 2009 High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs. The observed distribution of orbital eccentricity and period of binary radio pulsars in GCs have imprints of the past interaction between ...

A Perspective of Multi‐Reflecting TOF MS
Mass Spectrometry Reviews, EarlyView.ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.

X-ray Pulsar Signal Denoising Based on Variational Mode Decomposition
Entropy, 2021 Pulsars, especially X-ray pulsars detectable for small-size detectors, are highly accurate natural clocks suggesting potential applications such as interplanetary navigation control.

The Kinematics of Pulsars [PDF]
Symposium - International Astronomical Union, 1985 Pulsars have a galactic radial distribution similar to that of many galactic populations such as HII regions, massive stars and supernova remnants. However they are generally much further from the plane of the Galaxy than these objects. Proper motion measurements sho that this is because they are typically moving with high velocities.

Pulsar Spin-Velocity Alignment: Kinematic Ages, Birth Periods and Braking Indices [PDF]
, 2013 This paper presents a detailed investigation of the dependence of pulsar spin-velocity alignment, which has been observed for a sample of 58 pulsars, on pulsar age. At first, our study considers only pulsar characteristic ages, resulting in no change in the degree of correlation as a function of age, up to at least 100 Myr.

Re-visiting gravitational wave events via pulsars [PDF]
Physical Letters B 811, (2020) 135887, 2019 By now many gravitational wave (GW) signals have been detected by LIGO and Virgo, with the waves reaching earth directly from their respective sources. These waves will also travel to different pulsars and will cause (tiny) transient deformations in the pulsar shape.

Evolution of non-spherical pulsars with plasma-filled magnetospheres [PDF]
, 2015 Pulsars are famous for their rotational stability. Most of them steadily spin down and display a highly repetitive pulse shape. But some pulsars experience timing irregularities such as nulling, intermittency, mode changing and timing noise. As changes in the pulse shape are often correlated with timing irregularities, precession is a possible cause of

Systems Engineering Methodology for Digital Supply Chain Business Models
Systems Engineering, EarlyView.ABSTRACT Globalization and growing business dynamics lead to weakly harmonized supply chain (SC) systems. While smart technology offers innovation opportunities, supply chains often lack the integration needed to fully leverage resources and collaboration.
