Same Dangerous Objective, Opposite Advice: Direct Exposure versus Multi-Agent Mediation

Linjun Li

Even a current high-capability LLM can appear safer when shown a dangerous objective directly than when other agents transform and relay its direction. Using OpenAI's gpt-5.6-sol model alias, we test 25 pre-specified mirrored trade-off profiles. Direct exposure to an objective authorizing concealment, …

Crystallographic‐Orientation‐Independent Field‐Free Deterministic Magnetization Switching in Perpendicularly Aligned WTe 2 /Fe 3 GeTe 2 /WTe 2 Heterostructures

Xinyi Fan, Huanfeng Zhu, Junjian Mi, Jialin Li et autres

Spintronic devices utilizing spin‐orbit torque mechanisms still face challenges including high drive currents, the necessity of external magnetic fields, and sensitivity to crystallographic orientation. Here, we demonstrate field‐free deterministic magnetization switching in perpendicularly magnetized Fe 3 GeTe 2 (FGT) through WTe 2 …

Chiral phonons and giant magneto-optical Raman effect in chiral antiferromagnetic CoNb3S6

Junjian Mi, T.S. Wang, Wei Tang, Xinyi Fan et autres

Chiral phonons can reverse the helicity of incident light due to their nonzero pseudo-angular momenta. In this work, we investigated chiral phonon properties in an antiferromagnetic chiral CoNb3S6 using Raman spectroscopy and theoretical calculations. We observed two doubly degenerate chiral phonons and …

Impact of bronchial anastomosis wrapping on outcomes following sleeve lobectomy

Wei Guo, Qingyuan Wu, Dan Chen, Chun Huang et autres

Background: Sleeve lobectomy is widely used for the treatment of centrally located non-small cell lung cancer (NSCLC), aiming to preserve lung function while achieving complete tumor resection. Reinforcement of the bronchial anastomosis with autologous tissues, such as pericardium, has been proposed to …

Multi-GeV electron beam generation via two-stage laser wakefield acceleration

Rashid Ul Haq, Mohammad Rezaei-Pandari, Xinglong Xie, Xiao Liang et autres

Despite considerable progress in multi-stage laser wakefield acceleration (MSLWFA), efficient coupling between stages and the impact of laser-beam injection delay remains open challenges. A two-stage LWFA scheme is demonstrated using particle-in-cell (PIC) simulations, capable of producing multi-GeV electron beams over millimeter-scale propagation …

Stable b‐AsP/InSe Mid‐Infrared Detector with High Polarization‐Sensitivity for Target Feature Discrimination

Jiachang Chen, Xiangbao Xu, Cheng Chen, Jialin Li et autres

Abstract The development of next‐generation polarized mid‐infrared imaging systems demands miniaturization, high polarization ratio, room‐temperature operation and atmospheric stability. Compared to bulk materials, 2D anisotropic materials provide a new route for realizing miniaturized polarized photodetectors. However, their infrared sensing capabilities, particularly for …

Suppression of ablative Rayleigh–Taylor instability by spatially modulated laser in inertial confinement fusion

Zhantao Lu, Xinglong Xie, Xiao Liang, Meizhi Sun et autres

The suppression of ablative Rayleigh–Taylor instability (ARTI) by a spatially modulated laser in inertial confinement fusion (ICF) is studied through numerical simulations. The results show that in the acceleration phase of ICF implosion, the growth of ARTI can be suppressed by using …

Flat-band quantum materials empowering self-adapted ultrabroadband detectors

Jialin Li, Xun Ge, Junjian Mi, Hailu Wang et autres

Blackbody-sensitive room-temperature photodetectors with ultrabroadband response from the short to very long-wave infrared (VLWIR) range are highly desirable for optical communication, industrial gas leakage detection, night vision, and atmosphere surveillance. Although two-dimensional (2D) semiconductors with narrow bandgaps have shown promise in uncooled …

Antisymmetric Tunneling Magnetoresistance in Van der Waals Fe 3 GeTe 2 /Nb 3 Cl 8 /Fe 3 GeTe 2 Heterostructures Driven by Spin‐Splitting Potential Barrier

Xinyi Fan, Huanfeng Zhu, Junjian Mi, Linjun Li

Abstract Spintronic circuits exploit electronic spin other than charge as an information carrier, consuming several orders of magnitude less energy than conventional electronic circuits. 2D ferromagnets and topological material harbor spin polarization and spin dependent transport properties, bearing great application potential in …
