Abstract Extracellular vesicles (EVs) have been proved a promising small interfering RNA (siRNA) delivery vehicle to mediate gene‐silencing. Tumour‐derived extracellular (TDEVs) as genetic exchange vectors in the tumour microenvironment, enable intercellular communication for wide range of endogenous cargo molecules, such RNAs and proteins. However, oncogenic TDEVs limits their application siRNA cancer therapy. Herein, we isolated from hepatocellular carcinoma (HCC) cells derived TDEV...
In this paper, a 3D jerk chaotic system with hidden attractor was explored, and the dissipativity, equilibrium, stability of were investigated. The types, Lyapunov exponents, Poincare section under different parameters analyzed. Additionally, circuit carried out, good similarity between experimental results theoretical analysis testifies feasibility practicality original system. Furthermore, robust feedback controller designed based on finite‐time theory, which guarantees synchronization...
In this study, we reported a fluorescent nanoprobe assembled with upconversion core/shell nanoparticles and chromophore ruthenium complex (N719@UCNPs). Functional groups (NCS) of the N719 could react Hg2+, which made lose efficacy in quenching fluorescence (UCNPs) resulted recovery intensity UCNPs eventually. This provide rapid efficient detection Hg2+ ions vivo based on resonance energy transfer (FRET) between N719, limit 0.1 μg mL-1 can be achieved nanoprobe. It's worth mentioning that,...
In this paper, the vibration suppression and trajectory tracking control of a flexible joint manipulator (FJM) based on particle swarm optimization (PSO) fixed-time nonsingular terminal sliding mode (NTSMC) are studied. Firstly, in order to suppress residual FJM, an optimal planning method higher-order (HOTP) PSO algorithm is proposed. Then, ensure that FJM can track optimized without being affected by initial value trajectory, novel NTSMC scheme Compared with cubic spline proposed HOTP...
In this paper, a microfiber knot resonator (MKR) was encapsulated in polydimethylsiloxane (PDMS), and its capability to sense temperature experimentally evaluated. A very high sensitivity of -12 nm/°C recorded for the MKR device, with diameter 2μm ring 95 μm. However, light-loss significant small MKR. We attribute low ratio ring-length microfiber-diameter. stable temperature-sensing performance negative 8.48 were obtained MKRs 3 μm mm. device non-uniform (in diameter) also fabricated...
This paper concentrates on the predefined‐time trajectory tracking for an uncertain robotic manipulator system. First, a modified control (PTC) algorithm is proposed. Subsequently, with help of proposed PTC and nonsingular design method terminal sliding mode, novel sliding‐mode (NTSMC) scheme ensuring convergence errors. The advantages newly are as follows. (i) Unlike conventional (SMC) which only guarantees surface, can guarantee (ii) Compared algorithm, reduce initial peaking enhance...
This paper proposes a novel robust fixed‐time control for the robot manipulator system with uncertainties. Based on uniform exact differentiator (URED) algorithm, term is constructed. Then, inverse dynamics (IDC) proposed. For proposed method, stability of closed‐loop uncertainties strictly proved. The newly method exhibits following two attractive features. First, scheme extends existing IDC to scheme. Second, nonsingular rather than commonly used approximate approach. Simulation result...
This paper proposes a new spiking-free fixed-time disturbance observer (DO)-based sliding mode control (SMC) scheme of maximum power extraction for the wind turbine system.
