Design of Motion Controller for Satellite-Borne Data Transmission Antenna by Lijiao Li, Ran Shi, Xiaohui Zhang, Jiyu Ma, Jun Zhang

“…The controller is firstly designed using the hardware description language VHDL, simulated in ModelSim software. Then, it is connected to the stepping motors through the LMD18200H bridge chip by using aerospace-grade FPGA, controlling the data transmission antennas to regulate the angle, go to zero-position, or stop rotation. …”

Charged superradiant instability in a spherical regular black hole by Yizhi Zhan, Hengyu Xu, Shao-Jun Zhang

“…It has been observed that the charged superradiant instability arises only within a specific range of the deformation parameter, potentially resulting in an instability growth rate with a maximum magnitude of approximately $$\text {Im} (M \omega ) \sim 10^{-3}$$ Im ( M ω ) ∼ 10 - 3 . This growth rate significantly exceeds the instability identified in ABG black holes discussed in prior research, suggesting a notable timescale for detecting this phenomenon in astrophysical scenarios. …”

An efficient transition-metal-free route to oligo-$\alpha $-pyridylamines via fluoroarenes by Nicolini, Alessio, Anderlini, Biagio, Roncaglia, Fabrizio, Cornia, Andrea

“…The new polynucleating tripodal proligand $\text{H}_6\text{tren(dpa)}_3$, containing thirteen nitrogen donors of four different types, was designed, synthesized, and isolated in good yield (${\sim }$60%) via a transition-metal-free triple N-arylation of $\text{H}_6$tren with HXdpa (X $=$ Br or F), using $\text{K}_2\text{CO}_3$ or $\text{Cs}_2\text{CO}_3$ as a base ($\text{H}_6$tren $=$ tris(2-aminoethyl)amine, HXdpa $=$ 6-halogeno-$N$-(pyridin-2-yl)pyridin-2-amine). …”

Vehicle state estimation based on extended Kalman filter and radial basis function neural networks by Yunfei Zha, Xinye Liu, Fangwu Ma, CC Liu

“…The effectiveness of the fusion method is verified by the co-simulation of MATLAB/Simulink and CarSim, and the real vehicle test. The results show that the change trend of the estimation result is consistent with the actual state parameters change trend, and the estimation accuracy after algorithm fusion is significantly improved compared to a single extended Kalman filter or radial basis function.…”

A Batalha de Aljubarrota. Novas Interpretações by João Gouveia Monteiro

“…Este artigo visa uma reinterpretação de conjunto da batalha, centrada em quatro pontos principais: i) a de que Aljubarrota não correspondeu à invenção de qualquer modelo táctico original; ii) a de que os Castelhanos não estiveram em superioridade numérica no combate; iii) a de que o famoso quadrado do Condestável português Nuno Álvares Pereira nunca existiu; iv) e a de que os homens que lutaram ao lado do monarca português não o fizeram por amor à Pátria, mas sim por interesse materiais, sociais e políticos bem concretos. …”

Hydrogen and hydrogen sulphide in volcanic gases: abundance, processes, and atmospheric fluxes by Aiuppa, Alessandro, Moussallam, Yves

“…We show, in particular, that gas-phase equilibrium in the H$_{2}$–H$_{2}$S–H$_{2}$O–SO$_{2}$ system is overall maintained upon cooling down to ${\sim }$600 °C, while quenching of higher temperature equilibria (at which Apparent Equilibrium Temperatures, AETs, largely exceed measured discharge temperatures) is more frequently observed for higher extents of cooling (e.g., at $T < 600$ °C). …”
