Broad‐Spectrum, Cell Envelope‐Active Marinocyclin Antibiotics From a Coral‐Derived Bacterium Are Effective Against Colistin‐Resistant Bacteria

Angewandte Chemie, EarlyView.
Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.

Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

Advanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Overburden Behavior and Coal Wall Spalling Characteristics Under Large-Mining-Height Conditions

Applied Sciences
Large-mining-height technology has been increasingly applied in thick seam mining to enhance productivity and resource recovery. However, it also intensifies strata pressure and complicates surrounding rock control, leading to greater overburden movement,

Overcoming the Nyquist Limit in Molecular Hyperspectral Imaging by Reinforcement Learning

Advanced Intelligent Discovery, EarlyView.
Explorative spectral acquisition guide automatically selects informative spectral bands to optimize downstream tasks, outperforming full‐spectrum acquisition. The selected hyperspectral data are used for tasks such as unmixing and segmentation. BandOptiNet encodes selection states and outputs optimal bands to guide spectral acquisition. Recent advances

Research on surrounding rock failure law of large mining height working face in thick loose layer based on microseismic monitoring

Gong-kuang zidonghua, 2022
The research on the movement law of surrounding rock under the condition of thick loose layer and thin bedrock mostly adopts theoretical research methods such as establishing a mechanical model and numerical calculation. It lacks research based on field dynamic measurement.
