We developed a compact, optical fiber scanning piezoelectric transducer (PZT) probe for endoscopic and minimally invasive coherence tomography (OCT). Compared with previous forward-mount designs, we present reverse-mount design that achieves shorter rigid length. The was mounted at the proximal end of quadruple PZT tube scanned inside hollow to reduce resonant frequency 338 Hz using 17-mm-long fiber. A 0.9 mm deflection achieved driving amplitude 35 V. Using GRIN lens-based 1.3×...
This paper presents a fully on-chip mixed-mode low-dropout (LDO) regulator with improved regulation and transient responses. With the help of digital part, supported maximum load current is significantly improved, while chip area overhead very small. A Miller compensation capacitor buffer stage are used to achieve stability improve power MOS gate slew rate. The ultra-fast voltage helps further recovery speed reduce due its wider swing. proof-of-concept LDO design fabricated in standard...
Flow-gated capillary electrophoresis (CE) is a hybrid of conventional and microchip CE since it employs fused silica as the separation channel while taking advantage well-controlled flow-gated injection, which adds versatility in terms efficiency, analytical throughput, ease coupling with sample pretreatment procedures.
To explore the optimal energy level of dual-layer spectral detector computed tomography (DLCT) images pancreatic neuroendocrine neoplasms (pNENs) and investigate value in their detection.This retrospective analysis included 134 pNEN patients with 136 lesions; they underwent contrast-enhanced DLCT scanning histopathological confirmation pNENs. Virtual monoenergetic (VMI) 40-100 keV, iodine concentration map (IC map), Z-effective atomic number (Zeff conventional were analysed. The was obtained...
A Power-area-efficient output-capacitorless low- dropout (OCL-LDO) regulator with fast transient response is presented in this paper. The proposed technique permits the to achieve small undershoot (overshoot) when load steps up (down) and consumes little extra power. LDO has been implemented fabricated a 0.18- μm CMOS process. It occupies an active area of0.0071mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . simulated results have...
Effective management and beneficial utilization of liquid digestate is becoming a bottleneck anaerobic digestion. Electrodialysis exhibits considerable potential in valorization; however, the process typically challenged by severe membrane fouling due to high organic matter content. In present study, bench-scale electrodialysis was carried out treat fresh mature with an aim investigating behavior dissolved (DOM) during using ultrahigh-resolution mass spectrometry. Organics that were easily...
Side-by-side calibration is enabled by alternate injections in flow-gated capillary electrophoresis to rapidly perform amino acid analysis, an important procedure measure acids various samples.
LIF detection often requires labeling of analytes with fluorophores; and fast fluorescent derivatization is valuable for high-throughput analysis flow-gated CE. Here, we report a fluorescein-labeling scheme amino acid neurotransmitters, which were then rapidly separated detected in This was based on the reaction between primary amines o-phthalaldehyde presence thiol, 2-((5-fluoresceinyl)aminocarbonyl)ethyl mercaptan (FACE-SH). The short time (<30 s) suited on-line mixing that directly...
This paper aims to study on swing-up control of linear spring-connected double inverted pendulum through establishing a mechanical model the with D'alembert Principle. Taking discrete quantity as design variables and terminal constraint condition objective function, laws are computed by an optimization method. The results simulating show that is realized successfully method therefore illustrates this effective feasible.
