Precise delineation of hepatic lesions from multi-phase MRI scans is paramount for the prompt diagnosis and treatment liver conditions. Conventional approaches typically emphasize either global or local features, often disregarding spatial interdependencies across modalities difficulties arising ambiguous tumor margins. To address these deficiencies, we propose AMHMF-Net, an advanced adaptive modality-channel-search Hadamard multimodal fusion network. This architecture leverages a dual...

We demonstrate an enhanced distributed acoustic sensing (DAS) system based on ultra-weak fiber Bragg grating (UWFBG) array and self-heterodyne detection. By using the interaction process between nearby UWFBGs, distribution of field along could be fully captured. Self-heterodyne detection was applied, leading to much lower noise density level for proposed system. The experimental results have shown that reconstructed with high fidelity even at rear end a 42 km long spatial resolution 11.7 m....
We report on the fabrication of a fiber Bragg grating (FBG) with multiple resonances in two-dimensional waveguide array microstructured optical containing 91 cores. Theoretical investigation reveals that these originate from identical and nonidentical mode couplings between forward-propagating backward-propagating LP0m-like (m=1, 2, 3; LP refers to linearly polarized) supermodes. Since both central wavelength minimum transmission resonant dips respond differently curvature axial strain, this...
A novel all-fiber on-line Raman cell based on metal (silver)-lined capillary is proposed, which could collect reflection and transmission signal simultaneously. In our configuration, two optical fiber tips are inserted into both sides of the hollow-core metal-lined to form a cell. The other ends closely bound together as Sagnac loop coupled with probe. Each tip not only works in mode, but also acts collection lens for mode side's excitation. structure extend interaction length between...
We proposed and experimentally demonstrated a technique using composite-double-probe-pulse (CDPP) to eliminate the influence of polarization fading for Ultra-weak FBG (UWFBG) array-based phase-sensitive optical time-domain reflectometry (Φ-OTDR). The CDPP is composed two pulses whose spatial interval equal twice adjacent UWFBGs in UWFBG array. first pulse has long duration, second one continuous short with orthogonal states. width half pulse, their modulation frequencies are different from...

Centrifugal microfluidics or lab-on-a-disc (LOAD) is a promising branch of lab-on-a-chip microfluidics. Besides effective fluid transportation and inherently available density-based sample separation in centrifugal microfluidics, uniform actuation flow on the disc makes platform compact scalable. However, natural radially outward force LOAD system limits its capacity to perform complex manipulation steps. In order increase freedom integration system, we propose binary platform. With help...
We propose an optofluidic sorting method for nanoparticles with different size by using optical waveguide splitter, and moreover, multiple cascaded splitters threshold could act as multi-level unit. For a directional coupler (DC) specific wavelength excitation, the power splitting ratio is related to coupling length gap between parallel waveguides. The further determines trapping force potential wells distribution of both output ports. Most importantly, well dependent on particle size....

The proposed MSR scheme offers promising solution for performance...
