Optimizing ABA-based chemically induced proximity for enhanced intracellular transcriptional activation and modification response to ABA

Abscisic acid(ABA)-based chemically induced proximity(CIp) is primarily mediated by the interaction of the ABA receptor pyrabactin resistance 1-like 1(pYL1) and the 2C-type protein phosphatase ABI1, which confers ABA-induced proximity to their fusion proteins, and offers precise temporal control of a wide array of biological processes. However, broad application of ABA-based CIp has been limited by ABA response intensity. In this study, we demonstrated that ABA-induced interaction between another ABA receptor pyrabactin resistance 1(pYR1) and ABI1 exhibited higher ABA response intensity than that between pYL1 and ABI1 in HEK293T cells. We engineered pYR1-ABI1and pYL1-ABI1 into ABA-induced transcriptional activation tools in mammalian cells by integration with CRISpR/dCas9 and found that the tool based on pYR1-ABI1 demonstrated better ABA response intensity than that based on pYL1-ABI1 for both exogenous and endogenous genes in mammalian cells. We further achieved ABA-induced RNA m6A modification installation and erasure by combining ABA-induced pYR1-ABI1 interaction with CRISpR/dCas13, successfully inhibiting tumor cell proliferation. We subsequently improved the interaction of pYR1-ABI1 through phage-assisted continuous evolution(pACE), successfully generating a pYR1 mutant(pYR1m) whose interaction with ABI1 exhibited a higher ABA response intensity than that of the wild-type. In addition, we tested the transcriptional activation tool based on pYRm-ABI1 and found that it also showed a higher ABA response intensity than that of the wild type. These results demonstrate that we have developed a novel ABA-based CIp and further improved upon it using pACE, providing a new approach for the modification of other CIp systems.

在电机闭环控制过程中,电流传感器故障、不同电流传感器的不一致性等因素可能导致系统失稳。为提高系统的容错能力,减小故障对控制系统稳定性的影响,提出一种基于单电流传感器的改进相电流重构技术。通过移动脉宽调制的脉冲矢量来消除母线电流采样盲区,进而通过母线电流重构获得三相电流。相比于传统电流重构方法,所提改进方法重构的电流更接近真实电流值,能够减小电流总谐波,降低电磁转矩脉动,提升系统的稳态性能。通过仿真和实验对比2种重构方法,证明了所提改进方法的优势。结果表明所提改进方法能有效实现电流重构,提升系统稳态性能。

跨境高等教育是全球化时代高等教育国际化的重要形式之一。20世纪90年代中期以来，在世界贸易组织《服务贸易总协定》的推动下，跨境高等教育快速发展，极大促进了发展中国家的高等教育能力建设，但同时也强化了由西方发达国家主导的“中心-边缘”格局，主要表现为：“由北向南”流向鲜明，引发了教育依附、教育主权削弱、经济利益驱动、新形式间接剥削、国家间教育发展不均衡等问题。在大变局时代的背景下，全球化、国际秩序转型出现“有限全球化”和“去中心化”,对跨境高等教育产生深刻影响。中国、印度等国家积极推进本国高等教育“走出去”,使跨境高等教育发展呈现“由南向南”“由南向北”的多向流动。欧洲一体化、俄罗斯与中亚国家的区域一体化、中国—东盟命运共同体的建设，推进了教育区域化发展，也使跨境高等教育发展出现协同性、共生性的特征。以上两个变化对跨境高等教育传统的“中心-边缘”格局形成了冲击，表征着全球跨境高等教育格局演进的趋向。

In situ calibrated angle between the quantization axis and the propagating direction of the light field for trapping neutral atoms

The recently developed magic-intensity trapping technique of neutral atoms efficiently mitigates the detrimental effect of light shifts on atomic qubits and substantially enhances the coherence time. This technique relies on applying a bias magnetic field precisely parallel to the wave vector of a circularly polarized trapping laser field. However, due to the presence of the vector light shift experienced by the trapped atoms, it is challenging to precisely define a parallel magnetic field, especially at a low bias magnetic field strength, for the magic-intensity trapping of85Rb qubits. In this work, we present a method to calibrate the angle between the bias magnetic field and the trapping laser field with the compensating magnetic fields in the other two directions orthogonal to the bias magnetic field direction. Experimentally, with a constantdepth trap and a fixed bias magnetic field, we measure the respective resonant frequencies of the atomic qubits in a linearly polarized trap and a circularly polarized one via the conventional microwave Rabi spectra with different compensating magnetic fields and obtain the corresponding total magnetic fields via the respective resonant frequencies using the Breit–Rabi formula. With known total magnetic fields, the angle is a function of the other two compensating magnetic ***, the projection value of the angle on either of the directions orthogonal to the bias magnetic field direction can be reduced to 0(4)° by applying specific compensating magnetic fields. The measurement error is mainly attributed to the fluctuation of atomic temperature. Moreover, it also demonstrates that, even for a small angle, the effect is strong enough to cause large decoherence of Rabi oscillation in a magic-intensity trap. Although the compensation method demonstrated here is explored for the magic-intensity trapping technique, it can be applied to a variety of similar precision measurements with trapped neutral atoms.
