ABS-Mamba: SAM2-Driven Bidirectional Spiral Mamba Network for Medical Image Translation

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Yifan Gao, Wenbin Wu, Keqing Wu, Xiaotong Guo | Summary: Accurate multi-modal medical image translation requires ha-rmonizing global anatomical semantics and local structural fidelity, a challenge complicated by intermodality information loss and structural distortion. We propose ABS-Mamba, a novel architecture integrating the Segment Anything Model […]

Weak transcription factor clustering at binding sites can facilitate information transfer from molecular signals

Posted by dbos Delft

Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Tamara Mijatović, Aimée R. Kok, Jos W. Zwanikken, Marianne Bauer, | Summary: Transcription factor concentrations provide signals to cells that allow them to regulate gene expression to make correct cell fate decisions. Calculations for noise bounds in gene regulation suggest that clustering or cooperative binding of […]

Rapid formation of a very massive star >50000 $M_odot$ and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters

Posted by dbos Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Flammini Dotti | Summary: Context. We present simulations of a massive young star cluster using textsc{Nbody6++GPU} and textsc{MOCCA}. The cluster is initially more compact than previously published models, with one million stars, a total mass […]

Resonant Self-Diffraction of Femtosecond Extreme Ultraviolet Pulses in Cobalt

Posted by dbos Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Alexei A. Maznev, Wonseok Lee, Scott K. Cushing, Dario De Angelis, Danny Fainozzi | Summary: Self-diffraction is a non-collinear four-wave mixing technique well-known in optics. We explore self-diffraction in the extreme ultraviolet (EUV) range, taking advantage of intense femtosecond EUV pulses produced by a free electron […]

Differentiable NMS via Sinkhorn Matching for End-to-End Fabric Defect Detection

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Zhengyang Lu, Bingjie Lu, Weifan Wang, Feng Wang, | Summary: Fabric defect detection confronts two fundamental challenges. First, conventional non-maximum suppression disrupts gradient flow, which hinders genuine end-to-end learning. Second, acquiring pixel-level annotations at industrial scale is prohibitively costly. Addressing these limitations, we propose a differentiable NMS […]

Symmetry in Fundamental Parameters of Galaxies on the Star-forming Main Sequence

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Enci Wang, Luis C. Ho, Huiyuan Wang, Yong Shi | Summary: The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stellar masses M_* across cosmic time. Despite its significance, the […]
