A new conjugated hyperbranched polymer (hb-TFO) containing tetraphenylethylene (TPE) units, a famous aggregation-induced emission (AIE) active group, as the core, was synthesized successfully with modest yield via one-pot Suzuki polymerization reaction. Thanks to the introduction of TPE moieties, hb-TFO exhibited aggregation-enhanced emission (AEE) property, and could work as explosive chemosensor...
Ultrasound imaging has been an effective tool for measuring the muscle architectures, including the pennation angle. In this work, we proposed a new approach combining wavelet transform (WT) and Hough transform (HT) to detect the straight line-shaped patterns of aponeurosis, fascicle or bone, and then to quantify the pennation angles in ultrasound images. The results indicated that the proposed algorithm...
