The synchronous signal transmission can promote the successful completion of minimally invasive renal failure surgery, so the synchronous signal transmission method of minimally invasive renal failure surgery based on nano molecular image probe is studied. The nanoprobe is constructed by loading different signal molecules, photosensitizers, acoustic sensitizers and thermosensitives through the method of double emulsion or film hydration; the near-infrared confocal endoscope molecular image diagnosis and treatment equipment is designed based on the nanoprobe, and the intraoperative highfrequency image is obtained through the diagnosis and treatment equipment; the high-frequency injection energy and signal synchronous transmission method is adopted, and the signal is added to the primary and secondary resonance circuit. In the coupling module, a higher frequency alternating signal is added into the resonant coupling voltage to modulate the signal into the transmission resonance system, which is transmitted from the energy transmission coupling coil to the secondary end, and the injected signal part of the coupling coil is demodulated at the other end to complete the transmission of the signal coupling transmission loop, so as to realize the high-frequency image energy and index data signal of minimally invasive renal failure surgery. The experimental results show that the designed nano molecular image probe has good stability, and the simulated signal transmission waveform is consistent with the transmission waveform of the principle analysis. Applying the proposed method to the minimally invasive surgery of renal failure, it is found that the success rate and image signal transmission efficiency of the minimally invasive surgery of patients 1-5 are higher than 99.5%, and the operation image transmission accuracy is high and the operation effect is excellent.

Background And Hypothesis: Sequential saccade planning requires corollary discharge (CD) signals that provide information about the planned landing location of an eye movement. These CD signals may be altered among individuals with schizophrenia (SZ), providing a potential mechanism to explain passivity and anomalous self-experiences broadly. In healthy controls (HC), a key oculomotor CD network transmits CD signals from the thalamus to the frontal eye fields (FEF) and the intraparietal sulcus (IPS) and also remaps signals from FEF to IPS.

The global epidemic of bovine coronavirus (BCoV) has caused enormous economic losses. The characterisation and genetic composition of endemic strains in Southwest China remain elusive. This study aimed to fill this gap by isolating three BCoV strains from this region and sequencing their whole genomes.

The endosomal escape of lipid nanoparticles (LNPs) is crucial for efficient mRNA-based therapeutics. Here, we present a cationic polymeric micelle (cPM) as a safe and potent co-delivery system with enhanced endosomal escape capabilities. We synthesized a cationic and ampholytic di-block copolymer, poly (poly (ethylene glycol) methacrylate--hexyl methacrylate)--poly(butyl methacrylate--dimethylaminoethyl methacrylate--propyl acrylate) (p(PEGMA--HMA)--p(BMA--DMAEMA--PAA)), via reversible addition-fragmentation chain transfer polymerization.

In this paper, we propose a random frequency division multiplexing (RFDM) method for multicarrier modulation in mobile time-varying channels. Inspired by compressed sensing (CS) technology which use a sensing matrix (with far fewer rows than columns) to sample and compress the original sparse signal simultaneously, while there are many reconstruction algorithms that can recover the original high-dimensional signal from a small number of measurements at the receiver. The approach choose the classic sensing matrix of CS-Gaussian random matrix to compress the signal.

Skulls with high optical scattering and acoustic attenuation are a great challenge for photoacoustic imaging for human beings. To explore and improve photoacoustic generation and propagation, we conducted the photoacoustic simulation and image reconstruction of the multi-layer brain model with an embedded blood vessel under different optical source types. Based on the optical simulation results under different types of optical sources, we explored the characteristics of reconstructed images obtained from acoustic simulations with and without skull conditions.
