In this paper, a novel high-order disturbance observer (HODO) for the mobile wheeled inverted pendulum (MWIP) system is first proposed. Based on choice method of optimal gain matrices, estimation accuracy HODO can be improved. Combining proposed and sliding mode control (SMC), new strategy designed balance speed MWIP system. The boundness error proved stability closed-loop achieved through appropriate selection surface coefficients. effectiveness all methods verified by experiments real
Donor–acceptor π-conjugated aggregation-induced red emission materials for live cell imaging.
In situ detecting and monitoring intracellular telomerase activity is significant for cancer diagnosis. this work, we report a facile fast-responsive bioprobe in detection imaging of with superior photostability. After transfected into living cells, quencher group labeled TS primer (QP) can be extended the presence telomerase. Positive charged TPE-Py molecules (AIE dye) will bind to as well extension repeated units, producing activity-related turn-on fluorescence signal. By incorporating...
Telomerase is a widely used tumor biomarker for early cancer diagnosis. On the basis of combined use aggregation-induced emission (AIE) fluorogens and quencher, quencher group induced high specificity strategy detection telomerase activity from cell extracts patients' urine specimens was creatively developed. In absence telomerase, fluorescence background extremely low due to short distance between AIE dye. addition enhances significantly. The in E-J, MCF-7, HeLa equivalent 5-10 000 cells...
Enzyme-assisted detection strategies of microRNAs (miRNAs) in vitro have accomplished both great sensitivity and specificity. However, low expression miRNAs a complex environment cells induces big challenges for monitoring tracking vivo. The work reports the attempt to carry miRNA imaging into live cells, by enzyme-aided recycling amplification. We utilize facile probes based yellow aggregation-induced emission luminogens (AIEgens) with super photostable property but without quencher, which...
In rehabilitation practice, motivating patients with neurological injuries to actively increase muscle activity and ensure their safety are important. Therefore, this study proposed a position-constrained assist-as-needed (AAN) control method for robots. A human-robot interaction system position constraints was first established based on prescribed performance. Aiming at implementing the AAN strategy, robot assistance level metric (RALM), constructed global continuous differentiable function...
Deep Neural Networks (DNN) are increasingly used in a variety of applications, many them with substantial safety and security concerns. This paper introduces DeepCheck, new approach for validating DNNs based on core ideas from program analysis, specifically symbolic execution. The idea is to translate DNN into an imperative program, thereby enabling analysis assist validation. A basic translation however creates programs that very complex analyze. DeepCheck novel techniques lightweight...
Tetraploid oysters are used to cross with diploids produce triploid that have become an important part of the oyster aquaculture industry worldwide. Although most tetraploid artificially induced autotetraploids, allotetraploids can be produced between closely related species, providing new opportunities for polyploid breeding and studying genome interactions. Using PacBio sequencing, Illumina high-throughput chromosome conformation capture scaffolding, we assembled first high-quality...
In pneumatic muscle actuators (PMAs)-driven robotic applications, there might exist unpredictable shocks which lead to the sudden change of desired trajectories and large tracking errors. This is dangerous for physical systems. this article, we propose a novel adaptive proxy-based robust controller (APRC) PMAs, effective in realizing damped response regulating behaviors PMA via virtual proxy. Moreover, integration APRC nonlinear disturbance observer further handles system...
Through their biomechanical properties, pedestrians interact with the structures they occupy. Although this interaction has been recognized by researchers, pedestrians' properties have not fully addressed. In paper, a spring-mass-damper (SMD) system, pair of forces, was used to model pedestrian for application in vertical human–structure (HSI). Tests were undertaken gait laboratory, where three-dimensional motion-capture system record pedestrian's walking motions at various frequencies. The...
Disruptive variation in intracellular pH and its fluctuations lysosomes have a close relationship with the more acidic lysosome lumen of cancer cells (pH 4.5-5.5). Traditional lysosome-targeted probes, such as LysoTracker Green DND-26 (LTG) Red DND-99 (LTR), can fluoresce when weak base units probes are removed after donating protons under photoinduced electron-transfer (PET) effect. However they only be used at low concentration to avoid aggregation-caused quenching (ACQ) effect also easily...
In this article, a robust trajectory tracking control method is proposed for the passive gait training exoskeleton system driven by pneumatic muscles (PMs).
