Theory of mind (ToM) has long been recognized to play a major role in children’s social functioning. However, no direct evidence confirms the causal linkage between two. In current study, we addressed this significant gap by examining whether ToM causes emergence lying, an important skill. We showed that after participating training learn about mental-state concepts, 3-year-olds who originally had unable lie began deceive consistently. This effect lasted for more than month. contrast,...
In recent years, the severe energy consumption identified in global power‐transmission process makes development of new generation transmission materials with high strength (mainly ultimate tensile strength) and outstanding electrical conductivity (EC) more urgent. Though Al its alloys received significant attention from scientific community past two decades due to their relatively mechanical properties excellent EC, increasing EC are often incompatible conductor alloys, which remains...
A highly sensitive inline gas pressure sensor based on the hollow core Bragg fiber (HCBF) and harmonic Vernier effect (VE) is proposed experimentally demonstrated. By sandwiching a segment of HCBF between lead-in single-mode (SMF) (HCF), cascaded Fabry-Perot interferometer produced. The lengths HCF are precisely optimized controlled to generate VE, achieving high sensitivity sensor. Meanwhile, digital signal processing (DSP) algorithm research mechanism VE envelope, thus providing an...
Abstract In addressing the significant security concerns associated with urban natural gas transportation, particularly potential catastrophic consequences of leaks, this paper introduces a novel approach for detecting and locating leaks in pipelines using weak fiber Bragg grating (w-FBG) array micro-strain sensing technology. The field pipeline model is established, w-FBG applied to leakage experiment, detected by analyzing change trend micro-strain. experiments under different pressures...
We have proposed and experimentally demonstrated a novel optical fiber sensor for simultaneous measurement of high temperature gas pressure based on Regenerated Fiber Bragg grating (RFBG) cascaded with homemade hollow core (HCBF). The HCBF functions as an anti-resonant reflecting waveguide acts sensing unit. sample was fabricated tested in our lab, exhibiting linear sensitivity −3.747 nm/MPa 25.925 pm/°C large-dynamic range 2 MPa 600 °C, respectively. RFBG, monitor, integrated to compensate...
In this paper, a self-mode-locking optoelectronic oscillator (SML-OEO) is proposed and experimentally analyzed for self-excited microwave pulse generation. The SML-OEO shows the ability to realize phase coherence of oscillating modes in OEO cavity, thus generating frequency comb (MFC) with characteristics periodic rectangular waveform temporal domain. On basis, introducing broadband electric bandpass filters (EBFs) different bandwidths loop provides flexibility choosing band resulting MFCs,...
In this paper, an agarose-coated fiber Bragg grating (AC-FBG)-based humidity sensing system with high sensitivity, leveraging the Vernier effect in optoelectronic oscillator (OEO), is proposed and experimentally demonstrated. Changes ambient induce effective expansion contraction of film morphology on AC-FBG, leading to shifts wavelength. The wavelength variations AC-FBG can be converted changes microwave signal through OEO system, effectively improving resolution demodulation. sensitivity...
Comparative studies of the bile microbiota in different biliary obstructive infections remain limited. This study aims to characterize and investigate differences microbial profiles across various diseases. included patients with diseases admitted Jinling Hospital Suqian First Hospital. The cohort consisted individuals benign disorders, malignant obstruction, obstruction secondary severe acute pancreatitis (SAP) or intestinal fistulas. A total 133 samples were collected from 118 analyzed...
A highly sensitive relative humidity (RH) sensor based on Fabry-Perot interferometers (FPI) is proposed and experimentally demonstrated. The fabricated by splicing a segment of hollow core Bragg fiber (HCBF) with single mode (SMF) functionalized chitosan ultraviolet optical adhesive (UVOA) composite at the end HCBF to form hygroscopic polymer film. reflection beams from point two surfaces film generate Vernier effect in spectrum, which significantly improves sensitivity sensor. To demodulate...
