A Fluorescent RNA-Based Genetically Encoded Mg2+ Sensor Allows Robust Detection of Mg2+ in Live Cells

Xin Xie, Bibi Zhang, Mingyan Liu, Yuzheng Zhao et autres

Magnesium plays crucial roles in many biological processes and the stabilization of biomolecules, including DNA, RNA, and proteins. Despite significant progress, however, our understanding of how cells regulate Mg2+ homeostasis and transport remains incomplete. One of the goals is to develop approaches …

Energy dynamics of a nonequilibrium unitary Fermi gas

Xiangchuan Yan, Jing Min, Dali Sun, Shi-Guo Peng et autres

We investigate the energy dynamics of a unitary Fermi gas driven away from equilibrium. The energy is injected into the system by periodically modulating the trapping potential of a spherical unitary Fermi gas, and due to the existence of SO(2,1) symmetry, the …

DeepSeek-V3.2: Pushing the Frontier of Open Large Language Models

DeepSeek-AI, Aixin Liu, Aoxue Mei, Bing Xue et autres

We introduce DeepSeek-V3.2, a model that harmonizes high computational efficiency with superior reasoning and agent performance. The key technical breakthroughs of DeepSeek-V3.2 are as follows: (1) DeepSeek Sparse Attention (DSA): We introduce DSA, an efficient attention mechanism that substantially reduces computational complexity …

Repeated Ancilla Reuse for Logical Computation on a Neutral Atom Quantum Computer

Juan A. Muniz, Daniel Crow, Hyosub Kim, Jonathan M. Kindem et autres

Quantum processors based on neutral atoms trapped in arrays of optical tweezers have appealing properties, including relatively easy qubit number scaling and the ability to engineer arbitrary gate connectivity with atom movement. However, these platforms are inherently prone to atom loss, and …

Long-Range Plasmon-Assisted Dipole–Dipole Interactions with Microcavities

Lei Guo, Bowen Kang, Min Zhang, Huatian Hu et autres

Long-range dipole-dipole interactions (DDIs) are essential for enabling scalable quantum technologies. However, their practical realization is fundamentally limited by spatial rapid decay and environmental noise. In this study, we propose a plasmon-assisted microcavities platform that integrates a photonic cavity with a plasmonic …

Shear viscosity of an ultracold Fermi gas in the BCS–BEC crossover

Jing Min, Xiangchuan Yan, Dali Sun, W. Lu et autres

Abstract We report on the measurement of shear viscosity in an ultracold Fermi gas with variable temperatures and tunable interactions. A quadrupole mode excitation in an isotropic harmonic trap is used to quantify the shear viscosity of the quantum gas within the …
