The design of high-performance luminescent MOF thermometers with multi-operation modes has been long sought but remains a formidable challenge. In this work, for the first time, we present multimodal ratiometric thermometer based on single-lanthanide metal–organic framework (MOF) DyTPTC-2Me (H4TPTC-2Me = 2′,5′-dimethyl-[1,1′:4′,1″-terphenyl]-3,3″,5,5″-tetracarboxylic acid). It not only characteristic luminescence Dy3+ in which atomic transitions from 4I15/2 and 4F9/2 states (thermally...
In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard Modulation Telescope (Insight-HXMT), which was launched on Jun. 15th, 2017. The new method 'Significance Enhancement Pulse-profile Orbit-dynamics' (SEPO) is adopted to determine orbit observations only one pulsar. test, Crab chosen and observed by Insight-HXMT from Aug. 31th Sept. 5th in Using 5-day-long observation data, determined successfully three telescopes onboard - High Energy (HE), Medium...
In this article, a PZT/Epoxy 1-3 piezoelectric composite based on picosecond laser etching technology is developed for the fabrication of high-frequency ultrasonic transducer. The design, fabrication, theoretical analysis, and performance piezocomposite transducer are presented discussed. According to test results, area PZT pillar [Formula: see text], average width kerf thickness text]. fabricated has resonant frequency 46.5 MHz, parallel 65 an electromechanical coupling coefficient 0.73....
Because Industry 4.0 is not a better solution to the problems of circular economy development process, European Union proposed 5.0 as supplement 4.0. However, presently, no relevant research exists on promotion under 5.0, and limited understanding this process fundamental obstacle for enterprises pursue digitalization sustainable operations. This study addresses knowledge gap by developing roadmap explaining use drivers support promote transformation economy. first screens literature...
Due to the small aperture of blood vessel, a considerable disadvantage current intravascular ultrasound (IVUS) imaging transducers is that their lateral resolution much lower than axial resolution. To solve this problem, single-element, 50 MHz, 0.6 mm diameter IVUS transducer with geometric focus at 3 was proposed in paper. The focusing based on geometric-shaped 1-3 piezocomposite. impedance/phase, pulse echo, acoustic intensity field, and were tested. For comparison, flat same...
This study analyzed the effects and influencing factors of shallowly-buried explosions in soil based on design implementation static explosion experiments numerical simulations. Based test data, a analysis model SPH-FEM was established process pit parameters shallowly buried were analyzed. The results calculations comparisons verified effectiveness method simulating soil. Furthermore, similarities differences between ALE methods simulation same assessed. relationships blasting radius...
Ultrasound-guided interventional biopsy is becoming an increasingly popular and valuable tool in the clinic. Conventionally, low-frequency (1–5 MHz) ultrasound probes are employed on patient's body surface for guiding procedures, leading to low imaging resolution puncture accuracy. Several efforts have been made achieve precise punctures, such as inserting a miniaturized high-frequency phased-array transducer into body. However, devices (introducer needles) all separate from those probes,...
Transmission cable has great influence upon the performance of high-frequency ultrasound transducers, especially for those intrusive applications, where front-end tuning circuits are unavailable. In this paper, a method modeling transducers by considering effect was proposed based on transmission line theory. A full examination various cables effects were achieved through model. Typical transducer characteristics, including output impedance and pulse-echo response attained good agreement...
We present a study of timing properties the accreting pulsar 2S 1417-624 observed during its 2018 outburst, based on Swift/BAT, Fermi/GBM, Insight-HXMT and NICER observations. report dramatic change pulse profiles with luminosity. The morphology profile in range 0.2-10.0keV switches from double to triple peaks at $\sim2.5$ $\rm \times 10^{37}{\it D}_{10}^2\ erg\ s^{-1}$ quadruple $\sim7$ s^{-1}$. high energies (25-100keV) shows significant evolutions as well. explain this phenomenon...
The equivalent circuit simulation plays an important role in the design of ultrasound transducer. However, existing methods are difficult to achieve effect matching and backing layer, not able accurately simulate transducer with cable. Especially application high frequency ultrasound, long cable has a great influence on performance To overcome these limitations, this paper proposed improved method, which combined Leach model transmission line model. It can realize complete cable, layer...
The accuracy of pedicle screw fixation is crucial for patient safety. Traditional navigation methods based on computed tomography (CT) imaging have several limitations. Therefore, this study aimed to investigate the ultrasonic propagation characteristics bone tissue and their relationship with CT results, as well potential application ultrasound in fixation.
Quantum vortices are fundamentally important for properties of superconductors. In conventional type-II superconductor they determine the magnetic response system and tend to form regular lattices. UTe$_2$ is a recently discovered heavy fermion exhibiting many anomalous macroscopic behaviors. However, question whether it has multicomponent order parameter remains open. Here, we study by employing scanning superconducting quantum interference device microscopy. We find vortex behavior which...
Fishery harvest of Coilia mystus in the Yangtze Estuary has declined dramatically since late 1990s. A full understanding reproductive biology this species is essential for effective management population. total 1072 females C. collected from area between May 2006 and September 2007 were analyzed to reveal general Females with increased gonadosomatic index (GSI) gonads developed stages IV V occurred mainly March through August, indicating a major spawning season period; there also few GSI...
The paper reports the length–weight relationships of 55 species from Three Gorges Reservoir (TGR) Yangtze River, China, and largest reservoir in world. A total 24,176 specimens were collected July 2012 to January 2015. Length–weight for 33 fish not recorded previously FishBase, maximum lengths computed eight are presented. a values varied between 0.00054 0.01923, b ranged 2.729 3.583. results will be useful application sustainable management conservation these fishes TGR River.
The focus was on the length–weight relationships of three schizothoracinae species endemic to Tibet, including Schizothorax oconnori Lloyd, 1908, Ptychobarbus dipogon (Regan, 1905) and Schizopygopsis younghusbandi Regan, 1905, all which are characterized by slow growth, late maturation vulnerability environment (Ma et al., 2010, 2012; Duan 2014).
