From Coarse to Fine: Recursive Audio-Visual Semantic Enhancement for Speech Separation
Audio-visual speech separation aims to isolate each speaker's clean voice from mixtures by leveraging visual cues such as lip movements and facial features. While visual information provides complementary semantic guidance, existing methods often underexploit its potential by relying on static visual representations. In this paper, we propose CSFNet, a Coarse-to-Separate-Fine Network that introduces a recursive semantic enhancement paradigm for more effective separation. CSFNet operates in two …

ENSAM: an efficient foundation model for interactive segmentation of 3D medical images
We present ENSAM (Equivariant, Normalized, Segment Anything Model), a lightweight and promptable model for universal 3D medical image segmentation. ENSAM combines a SegResNet-based encoder with a prompt encoder and mask decoder in a U-Net-style architecture, using latent cross-attention, relative positional encoding, normalized attention, and the Muon optimizer for training. ENSAM is designed to achieve good performance under limited data and computational budgets, and is trained from scratch o…

How Microplastics cross the Buoyancy Barrier: A multi-scale Study
Microplastics (MPs), though less dense than water, are frequently recovered from sediments in aqueous environments, indicating they can cross the buoyancy barrier. We quantify eco-corona mediated MP-sediment attraction and MP transport from the nanoscale to the macroscale, linking all scales to a coherent mechanism explaining how MP overcome buoyancy and settle in sediments through interaction with suspended sediment. Colloidal probe atomic force microscopy (CP-AFM) detected attractive forces…

Monolithic low-noise erbium-doped thin-film lithium niobate waveguide amplifier with 18 dB fiber to fiber net gain
Erbium-doped waveguide amplifiers have captured great attentions in recent years due to the rapid advance of photonic integration materials and fabrication techniques. In this work, a compact erbium-doped thin-film lithium niobate waveguide amplifier integrated with high-efficiency edge-couplers on the small footprint of 2 mm{\cross}25 mm, achieving >18 dB fiber-to-fiber (off-chip) net gain with bidirectional pumping by ~1480 nm laser diodes, is fabricated by the photolithography assisted chemo…
