We hereby proposed and experimentally demonstrated an active polarization imaging technique, based on wavelength selection, for seeing through highly turbid water where targets are always visually lost. The method was realized by making use of the dependence light scattering in water. Red illumination selected to minimize occurring propagation guarantee accurate estimation degree polarization. Experiments demonstrate its contribution turn from "undetectable" "detectable."

Cell-cultured meat, which is obtained by adsorbing cells on the three-dimensional scaffold, considered a potential solution to animal welfare issues. Edible and safe cell-cultured meat scaffolds are key part of its research. Soy protein isolate (SPI) hydrogel has network structure been studied for L929 cell culture because non-toxicity biocompatibility. However, toughness mechanical properties SPI not enough bear requirements cultivation. In this paper, sodium alginate (SA) was added...

Characterizations of circulatory and metabolic function in skeletal muscle are great importance clinical settings. Here this study, we investigate the utility photoacoustic tomography (PAT) to monitor hemodynamic changes forearm during cuff occlusion. We show high quality (PA) images human comparison with ultrasound images. Besides, track occlusion cross-validated near-infrared spectroscopy. Our study suggests that PAT, as a new tool, could be applied common diseases affecting future.

Limb perfusion monitoring is critical for diabetes mellitus (DM) patients as they are vulnerable to vascular complications due prolonged hyperglycemia. However, current clinical approaches ineffective in imaging and assessing function lower limbs. In this work, a concave ultrasound transducer array-based photoacoustic tomography (PAT) system was used image the foot dorsal section of subject, total seven DM healthy volunteers were enrolled study. Hemodynamic changes vessels during occlusion...

Target positioning by the magnetic tracking system is extremely susceptible to influence of geomagnetic field. To accurately locate objects, we design a second-order gradient tensor (SMGT) based on plane-cross (MGT) system. With constraint equation MGT spatial invariants, source position coordinates are solved SMGT and Euler deconvolution. The simulation shows when Gaussian noise variance less than 3 nT dipole with scalar 6000 Am <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Photoacoustic imaging (PAI) provides real-time noninvasive and contrast agent-free monitoring of the concentrations some endogenous compounds related to tumor vascularization oxygenation. In this study, we used PAI noninvasively evaluate responses antiangiogenic therapy.In vivo studies were performed with approval our institutional animal ethics committee. We a xenograft mouse model 4T1 breast cancer treated different doses bevacizumab or vehicle. Seven days after implantation, tumor-bearing...

The magnetic gradient tensor system (MGTS) based on the fluxgate sensors array replaces partial differentials with reading difference to approximate field gradient, but it introduces structural errors at mean time. A good structure design reasonable parameters can reduce and expand theoretical detection range of MGTS. From analysis complete 18-uniaxial MGTS, five simplified structures MGTS were summarized, which include plane cross, equilateral triangle, square, right-angle tetrahedron,...

New functionalized tris(2′,6′-difluoro-2,3′-bipyridinato-N,C4′)iridium(III) ((dfpypy)3Irs) complexes, including small molecules and their dendrimer embedded analogoues, were synthesized characterized. It is demonstrated that both the fac-(dfpypy)3Ir-based polyphenylene dendrimers (triisopropylsilyl)ethynyl (TIPSE)-substituted (dfpypy)3Ir complexes induce large bathochromic shifts (∼50 nm) of emission bands compared with fac-(dfpypy)3Ir. This due to pronounced 3π–π* character emissive excited...

In geotechnical reliability analysis, random volatility in marginal distributions of shear strength parameters has been rarely considered. Unfortunately, conventional distribution models cannot characterize real probability accurately, leading to considerable dispersion with incomplete probabilistic information. this paper, an estimation methodology is proposed based on copula theory coupling information diffusion technique. Firstly, extended represent one‐dimensional parameters. Secondly,...

Finally, effects different on accuracy evaluated using results. The result showed...

The classical visual Simultaneous Localization and Mapping(SLAM) algorithms assume that the camera moves in a free 3D space, while it is not valid for ground vehicles whose poses are influenced by surfaces. In recent years, researchers have focused on improving pose estimation accuracy assuming planar motion which more suitable to indoor environments. this paper, we propose lightweight stereo-visual SLAM framework road environments tightly integrates constraints imposed We vehicle exhibits...
