Robust Beamforming and Antenna Position Optimization for MA-Assisted ISAC with Imperfectly Positioned MAs

Zeyuan Zhang, Ning Wei, Ahmad Bazzi, Boyang Jia et autres

This paper investigates robust beamforming and antenna position design for movable antenna (MA)-enabled integrated sensing and communication (ISAC) systems under antenna position errors. In particular, deviations between the actual and nominal antenna positions in practical MA arrays are inevitable due to limited …

All electrical sub-nanosecond field-free switching of perpendicular magnetization with high magnetic field immunity

Jiyu Shen, Jun Cheng, Yulun Zeng, Zeyuan Zhang et autres

Spin-orbit torque magnetic random-access memory is a promising next-generation non-volatile memory technology featuring low power consumption, rapid operation, and high endurance. Conventional spin-orbit torque-induced deterministic perpendicular magnetization switching, however, typically requires the assistance of an external magnetic field. While multiple field-free switching …

Crosstalk-Resilient Beamforming for Movable Antenna Enabled Integrated Sensing and Communication

Zeyuan Zhang, Yue Xiu, Zheng Dong, Jiacheng Yin et autres

This paper investigates a movable antenna (MA)-enabled integrated sensing and communication (ISAC) system under the influence of antenna crosstalk. First, it generalizes the antenna crosstalk model from the conventional fixed-position antenna (FPA) system to MA. Then, a Cramer-Rao bound (CRB) minimization problem …

Single‐Atom‐Modulated Reactive Oxygen Species Generation and Network Crosslinking in Porphyrin‐Based Metallacages for Selective Photocatalysis

Yiqin Zhang, Shijin Jian, Zixuan Li, Yujuan Huang et autres

Abstract Precise control over the photocatalytic selectivity by single atoms is ubiquitous in natural systems but remains a formidable challenge for artificial photocatalysts. Here, we present a series of porphyrin‐based metallacages with nearly identical architectures that differ only in the central metal …

Novel Low Resolution Direct Learning Digital Predistortion Architecture Based on Signal Folding

Zeyuan Zhang, Yan Li, Kuo Liao, Ning Wei

Digital predistortion (DPD) is widely used in all kinds of wireless communication systems to improve signal quality and energy efficiency. However, the conventional DPD structures rely heavily on the high-resolution feedback analog-to-digital converter (ADC) to capture the output of the power amplifier. …

Oligomeric HIV-1 integrase structures reveal functional plasticity for intasome assembly and RNA binding

Tao Jing, Zelin Shan, Tung Dinh, Avik Biswas et autres

Integrase (IN) performs dual essential roles during HIV-1 replication. During ingress, IN functions within an oligomeric “intasome” assembly to catalyze viral DNA integration into host chromatin. During late stages of infection, tetrameric IN binds viral RNA and orchestrates the condensation of ribonucleoprotein …

Directional Electron Transfer in Porphyrin‐Based Heteroleptic Metallacages for Enhanced Visible Light‐Driven Photocatalysis

Zeyuan Zhang, Zixuan Li, Lei Zhang, Shijin Jian et autres

Abstract The rational design of supramolecular architectures capable of mediating directional photoinduced electron transfer (PET) remains a central challenge in confined photocatalysis. Herein, we report two porphyrin‐based heteroleptic metallacages, constructed via multicomponent coordination‐driven self‐assembly, for the visible light‐driven oxidative coupling of tetraorganoborates. …
