The worldwide outbreak of severe acute respiratory syndrome (SARS) in 2003 had caused a high rate of mortality. Main protease (M-Pro) of SARS-associated coronavirus (SARS-CoV) is an important target to discover pharmaceutical compounds for the therapy of this life-threatening disease. During the course of screening new anti-SARS agents, we have identified that a series of unsymmetrical aromatic disulfides inhibited SARS-CoV M-Pro significantly for the first time. Herein, 40 novel unsymmetrical aromatic disulfides were synthesized chemically and their biological activities were evaluated in vitro against SARS-CoV M-Pro. These novel compounds displayed excellent IC50 data in the range of 0.516-5.954 mu M. Preliminary studies indicated that these disulfides are reversible and mpetitive inhibitors. A possible binding mode was generated via molecular docking simulation and a comparative field analysis (CoMFA) model was constructed to understand the structure-activity relationships. The present research therefore has provided some meaningful guidance to design and identify anti-SARS drugs with totally new chemical structures. (C) 2017 Elsevier Masson SAS. All rights reserved.

A greedy-based hybrid trajectory optimization method for the ?Dyson Ring? building problem

Xuewen Liu, Xinxi Zeng, Changbao Shao, Yuanjing Xu, Jincheng Hu, Pengxuan Liu, Hongwei Yang, Shuang Li

Summary: The paper presents the method and results of the team ASTL-NUAA from NUAA for solving the problem of GTOC 11. The problem is decomposed into three parts: optimization of multiple targets flyby sequence for Mother Ships, construction of a station-building database for asteroid transfer arcs, and mission planning for station-building. A three-step optimization framework is proposed to solve the problem. The optimal solutions are obtained by analyzing and selecting candidate asteroids, applying a genetic algorithm for asteroid flyby sequence determination, constructing a station-building database with less computation burden, and using a branch-and-bound algorithm for maximizing minimal mass among stations. The final score of the solution is 4315.6663, achieved after the competition.

Summary: This paper proposes and verifies an optimal estimation method for satellite attitude deviation in orbit using the frequency domain features of microwave remote sensing data. The method is applied to the Gaofen-3B (GF-3B) satellite and involves obtaining Synthetic Aperture Radar (SAR) imaging results and Doppler center deviation inversions. A model is established between the Doppler center deviation and satellite attitude deviation, allowing for the separation and estimation of attitude deviations in different dimensions. The proposed method successfully suppresses attitude deviation and improves image quality of SAR satellites.

Distributed cooperative control with collision avoidance for spacecraft swarm reconfiguration via reinforcement learning

Jun Sun, Yizhen Meng, Jing Huang, Fucheng Liu, Shuang Li

Summary: This article investigates an adaptive, distributed, and cooperative control strategy for the problem of spacecraft swarm reconfiguration, which involves assembling the spacecraft at a close distance to one another while avoiding collisions and keeping spacecraft far from an obstacle. The proposed control strategy is inspired by the actor-critic framework of reinforcement learning (RL) algorithms and utilizes a combination of critic neural network (NN) and artificial potential field (APF) to address the soft and hard constraints. The adaptive, distributed, and cooperative controller is devised using an actor NN of the RL algorithm, an APF, and Backstepping control technology.

Densely rewarded reinforcement learning for robust low-thrust trajectory optimization

Jincheng Hu, Hongwei Yang, Shuang Li, Yingjie Zhao

Summary: To address the issue of time-consuming training in reinforcement learning caused by sparse reward functions, an efficient dense reward framework is proposed for robust low-thrust trajectory optimization. The framework includes dense reward functions designed separately for deterministic and uncertain scenarios, and incorporates exponential acceleration terms to improve training efficiency in rendezvous missions. Empirical forbidden zones and exponential terms are also introduced to design a dense reward function for the deterministic scenario. The method is demonstrated to be effective and efficient in Earth-Mars and Earth-Venus missions.

Continuous quaternion curves are calculated through segmented cubic spline interpolation function. The method is verified to be feasible and capable of satisfying complex constraints, obtaining attitude optimization path, and alleviating large control moment variations during maneuver.

Pseudospectral Convex Optimization Based Model Predictive Static Programming for Constrained Guidance

Xu Liu, Shuang Li, Ming Xin

Summary: This article presents a pseudospectral convex optimization-based model predictive static programming (PCMPSP) for the constrained guidance problem. The sensitivity relation between the state increment and control correction is reformulated using Legendre-Gauss and Legendre-Gauss-Radau pseudospectral transcriptions. Modifications to the initial guess solution and reference trajectory update are introduced to enhance the accuracy and robustness of the algorithm. The simulation results demonstrate that the PCMPSP has better performance compared to existing convex programming methods in terms of sensitivity, accuracy, and convergence speed.

Indirect sequential convex programming for mars entry terminal altitude maximization

Xu Liu, Shuang Li, Ming Xin

Summary: This article introduces a method called Indirect Sequential Convex Programming (ISCP), which combines the Uniform Trigonometrization Method (UTM) and Sequential Convex Programming (SCP) to solve difficulties in the Mars entry problem. The ISCP method eliminates the need for evaluating two possible solutions through Pontryagin's minimum principle (PMP) and solves the nonlinear two-point boundary value problem (TPBVP) by relaxing it into a convex programming problem. Simulations show the effectiveness and efficiency of the ISCP method for Mars entry missions.
