Abstract Background The association between the intestinal microbiota and colorectal cancer (CRC) has been extensively studied, with Fusobacterium nucleatum ( F. , FN) being found in high abundance tissues. Previous research emphasized significant role of occurrence CRC. However, impact on CRC liver metastasis not well understood. Methods effects ability cell were evaluated vitro examined by wound-healing assay transwell assay. mouse model was constructed spleen injection, degree assessed...
In order to provide better monitoring for the elderly or patients, we developed an integrated wireless wearable sensor system that can realize posture recognition and indoor localization in real time. Five designed nodes which are respectively fixed on lower limbs a standard Kalman filter used acquire basic attitude data. After angles of five body segments (two thighs, two shanks waist) obtained, pitch left thigh waist recognition. Based all these segments, also calculate coordinates six...
This paper addresses the fault detection and isolation (FDI) problem for robotic assembly of electrical connectors in framework set-membership. Both fault-free faulty cases are modeled by different switched linear models with known switching sequences, bounded parameters, external disturbances. The locations points each model assumed to be inside some areas but accurate positions not clear. Given current input/output data, feasible parameter set is obtained sequentially calculating an...

The use algorithm significantly improves the performance microgripper. An experiment shows has large displacement (91.5 μm) low actuation voltage (47.5 V), which agrees well theory. and can handle micro-objects size from 10 100 μm. A...
This article presents a nano-g microopto-electromechanical system (MOEMS) accelerometer that uses the principle of Fabry–Pérot (F-P) interference in conjunction with micromechanical structure for transducing input acceleration. The device comprises movable silicon proof mass suspended by flexural beams and an F-P cavity integrated cleaved optical fiber. Furthermore, closed-loop force balance mechanism is exploited to enhance accelerometer's measurement range utilizing magnetic provided pair...
This work reports a multiple-parameter decoupling (MPD) method based on resonant MEMS sensors subject to blue-sideband excitation (BSE), thus enabling simultaneous separation of the cross-coupled physical quantities, e.g. acceleration and temperature, single sensor. Such technique exploits property BSE that multiple vibration modes resonator can be excited at same time. The proposed MPD algorithm is applied two distinct sensors, i.e. base-line electrostatic force sensor, vacuum-packaged...

In this work, a zeolitic imidazolate framework-8 (ZIF-8)-coated coupled resonant sensor was fabricated using solvent-free method. The method avoids the use of solvents for ZIF-8 synthesis, which eliminates risk device contamination, corrosion, or destruction. This process enables batch fabrication ZIF-8-coated resonators at wafer level. By tracking shifts in frequency and amplitude ratio, demonstrates strong responses to ethanol vapor different concentrations exhibits good reversible...
In this paper, a new approach for enhancing the temperature sensitivity of resonant MEMS thermometer, based on parametric modulation, is proposed. By periodically modulating effective stiffness standard clamped-clamped beam (C-C beam), which used as proof-of-concept it possible to create virtual energy coupling between two fundamental modes vibration. Through transfer link, one particular mode (ideally high sensitivity) can be transferred vicinity another low noise), thus creating an...
Anisotropic nanostructures can be generated in fused silica glass by manipulating the spatiotemporal properties of a picosecond pulse. This phenomenon is attributed to laser-induced interband self-trapped excitons. The anisotropic structures exhibit birefringent properties, and thus employed for multi-dimensional optical data storage applications. Data voxels such short laser irradiation enable on-the-fly high-speed recording.

This letter conducts a thorough comparison between two temperature compensation methods for resonant micro-electro-mechanical-system (MEMS) sensors, i.e., 1) newly proposed in-situ technique based on multiple parameter decoupling (MPD) using single MEMS sensor subject to blue-sideband excitation, and 2) the prevailing method utilizing sensor, which, in this letter, is thermometer close vicinity of sensor. Experimental results show that MPD-based offers better noise performance, long-term...
