Multiple Spacecraft Formation Flying Control around Artificial Equilibrium Point Using Propellantless Approach by Lei Zhao, Changqing Yuan, Xiaoming Li, Jingjiu He

“…Secondly, considering the external disturbances in the deep space environment, the nonlinear dynamic model of the spacecraft formation system based on the circular restricted three-body problem (CRTBP) is derived, under the assumption that the leader covers the nominal trajectory and each follower adjusts its propulsive acceleration vector (that is, both its sail attitude and electrostatic charge) in order to track a desired relative trajectory. …”

The bacterial response regulator ArcA uses a diverse binding site architecture to regulate carbon oxidation globally. by Dan M Park, Md Sohail Akhtar, Aseem Z Ansari, Robert Landick, Patricia J Kiley

“…We propose that this plasticity in ArcA binding site architecture provides both an efficient means of encoding binding sites for ArcA, σ(70)-RNAP and perhaps other transcription factors within the same narrow sequence space and an effective mechanism for global control of carbon metabolism to maintain redox homeostasis.…”

Quantum complexity of time evolution with chaotic Hamiltonians by Vijay Balasubramanian, Matthew DeCross, Arjun Kar, Onkar Parrikar

“…This complexity is expected to increase linearly for exponential time prior to saturating at its maximum value, and is related to the length of minimal geodesics on the manifold of unitary operators that act on Hilbert space. Using the Euler-Arnold formalism, we demonstrate that there is always a geodesic between the identity and the time evolution operator e−iHt whose length grows linearly with time. …”

A Virtualization Approach to Correct Systematic Errors in Measured TDOA and FDOA for Low Orbit Dual-Satellite Positioning Systems by Gang Li, Min Zhou, Hongwen Tang, Hongbin Chen

“…The low-orbit dual-satellite passive location system provides a cost-efficient and easy implementation platform, by which positions of unknown emitters on the Earth can be determined through measuring both the time and the frequency differences by two low-orbit satellites in space. However, in reality, this dual-satellite location system has low positioning accuracy because of the existence of systematic errors. …”
