By harnessing the capabilities of large language models (LLMs), recent large multimodal models (LMMs) have shown remarkable versatility in open-world multimodal understanding. Nevertheless, they are usually parameter-heavy and computation-intensive, thus hindering their applicability in resource-constrained scenarios. To this end, several lightweight LMMs have been proposed successively to maximize the capabilities under constrained scale (e.g., 3B). Despite the encouraging results achieved by these methods, most of them only focus on one or two aspects of the design space, and the key design choices that influence model capability have not yet been thoroughly investigated. In this paper, we conduct a systematic study for lightweight LMMs from the aspects of model architecture, training strategy, and training data. Based on our findings, we obtain Imp - a family of highly capable LMMs at the 2B$\sim$4B scales. Notably, our Imp-3B model steadily outperforms all the existing lightweight LMMs of similar size, and even surpasses the state-of-the-art LMMs at the 13B scale. With low-bit quantization and resolution reduction techniques, our Imp model can be deployed on a Qualcomm Snapdragon 8Gen3 mobile chip with a high inference speed of about 13 tokens/s. © 2025 IEEE.

Effectively reconstructing 3D hyperspectral images (HSIs) from 2D measurements presents a significant challenge in Coded Aperture Snapshot Spectral Imaging (CASSI) systems. While recent transformers exhibit potential in HSI reconstruction, they often suffer from inadequate exploration of multi-scale spatial-spectral self-similarity, leading to mean effects and information loss. Additionally, these methods struggle with insufficient modeling of the degradation inherent in the compressive imaging process. To address these issues, we propose a novel Mask-guided Multi-scale Spatial-Spectral Transformer (MMSST). Specifically, we introduce a Degradation Aware Mask Attention (DAMA) module to incorporate degradation information of the compressive imaging process. Furthermore, MMSST leverages Local-Regional SpAtial attention (LRSA) and Global-Regional SpEctral attention (GRSE) to effectively exploit multi-scale self-similarity across spatial and spectral dimensions. Extensive experimental results demonstrate the effectiveness of our MMSST. © 2025 IEEE.

INSPIRED by the insight from American political scientist Lasswell, who summarized the environmental role in societal surveillance [1], Schramm coined the term “social radar” [2] as it resembles the activities of radar in collecting and processing information, playing a crucial role in helping humans perceive changes in the internal and external environment and promptly adjusting adaptive behaviors.

Cryo-EM structure of a minimal reaction center–light-harvesting complex from the phototrophic bacterium Chloroflexus aurantiacus

Journal of Integrative Plant Biology 2025年第4期 967-978页

作者： Guoqiang Huang Shishang Dong Lin Ma Lin Li Jinxin Ju Mei-Jiao Wang Jian-Ping Zhang Sen-Fang Sui Xiaochun Qin State Key Laboratory of Membrane Biology Beijing Advanced Innovation Center for Structural Biology School of Life SciencesTsinghua University Multiscale Research Institute of Complex Systems Fudan University School of Biological Science and Technology University of Jinan School of Chemistry and Life Resources Renmin University of China School of Life Sciences Southern University of Science and Technology

Photosynthetic organisms have developed various light-harvesting antenna systems to capture light and transfer energy to reaction centers（RCs）.Simultaneous utilization of the integral membrane light-harvesting antenna（LH complex） and the extrinsic antenna（chlorosomes） makes the phototrophic bacterium Chloroflexus（Cfx.） aurantiacus an ideal model for studying filamentous anoxygenic phototrophs（FAPs）. Here, we determined the structure of a minimal RC–LH photocomplex from Cfx. aurantiacus J-10-fl（CaRC–LH） at 3.05-? resolution. The CaRC–LH binds only to seven LH subunits, which form a crescent-shaped antenna surrounding the movable menaquinone-10（QB）binding site of Ca RC. In this complex with minimal LH units, an extra antenna is required to ensure sufficient light-gathering, providing a clear explanation for the presence of chlorosomes in Cfx. aurantiacus. More importantly, the semicircle of the antenna represents a novel RC–LH assembly pattern. Our structure provides a basis for understanding the existence of chlorosomes in *** and the possible assembly pattern of RC–LH.

In order to study the damage characteristics of typical armored vehicle track under shock wave load, the finite element software LS-DYNA was used to simulate the process of shock wave damage to typical armored vehicle track. Eight simulation conditions were set up to obtain the influence rules of explosion conditions and track structure on shock wave damage, and the influence of explosive charge, explosive distance and track structure on damage effect was analyzed. The results showed that when the explosive charge exploded on the track side, the track deformation and fracture occurred at the position corresponding to the explosion center level, and the damage degree of shock wave to track changed with the explosive charge and track length. © 2023 SPIE.
