Abstract Diagnostics is the key in screening and treatment of cancer. As an emerging tool precision medicine, metabolic analysis detects end products pathways, thus more distal than proteomic/genetic analysis. However, far from ideal clinical diagnosis due to sample complexity metabolite abundance patient specimens. A further challenge real‐time accurate tracking effect, e.g., radiotherapy. Here, Pd–Au synthetic alloys are reported for mass‐spectrometry‐based fingerprinting analysis, toward...
Due to the asymmetric and dynamic nature of turbulent flames encountered in practical combustors, three-dimensional measurements have been long desired resolve complex flame structures. Volumetric tomography has demonstrated be a powerful tool for this purpose. However, applications, typically only few high-speed cameras can applied due their high expense limited optical access combustor. Thus, camera arrangement is paramount importance order fully explore useful information target fields....
Combustion is the dominant form of energy conversion for a span power systems such as engines and plant boilers. It an extremely complicated process which produces huge number intermediate products that usually feature non-uniform spatial distributions. Among those products, free radicals emitting in UV band are special interest because they contain abundant useful information target flame. Imaging methods planar laser-induced fluorescence or chemiluminescence imaging with cameras paramount...
This paper proposes a novel algorithm to clean up large collection of historical handwritten documents kept in the National Archives Singapore. Due seepage ink over long period storage, front page each document has been severely marred by reverse side writing. Earlier attempts have made match both sides identify offending strokes originating from back so as eliminate them with aid wavelet transform. Perfect matching, however, is difficult due skews, differing resolutions, inadvertently...
Fiber optic methane gas detecting system based on distributed feedback (DFB) laser wavelength scanning technique is demonstrated. Wavelength scan of absorption peak at 1665.9 nm realized by saw tooth modulation current which injected to DFB laser. A reference cell used find the around 1666 nm, and normalization reduce outside affection such as power drift, fiber loss. Concentration got arithmetic processing coefficient gas. In-situ test carried out in coalmine long time precision 0.05%...
This study designs a spectrum data collection device and system based on the Internet of Things technology, aiming to solve tedious process chlorophyll provide more convenient accurate method for predicting content. The has advantages integrated design, portability, ease operation, low power consumption, cost, maintenance requirements, making it suitable outdoor analysis in fields such as agriculture, environment, geology. core processor uses ESP8266-12F microcontroller collect by...
The diffuse reflection (DR) spectrum of a sample consisting mixture rare earth oxides and talc was measured at 2 cm −1 resolution, using five different accessories installed on Fourier transform near-infrared (FT-NIR) spectrometers from four manufacturers. Peak positions for 37 peaks were determined two peak-picking algorithms: center-of-mass polynomial fitting. wavenumber the band center reported by either these techniques sensitive to slope baseline, so baseline spectra corrected fit or...
Acute lung injury (ALI) features dysregulated pulmonary inflammation. Ultrashort waves (USWs) exert anti-inflammatory effects but no studies have evaluated their activity in ALI. Herein, we used an vivo lipopolysaccharide (LPS)-induced ALI model to investigate whether the of USWs is mediated by altering polarization M1 M2 macrophages. Twenty-four male Sprague-Dawley rats were randomly divided into control, untreated ALI, and treated with USW groups (n = 8 each group). was induced...
Flame emission tomography is a promising tool for combustion diagnostics. Up to now, this technique relies on the assumption that distribution within voxel uniform. Such an suffers from large gradient between adjacent voxels and loss of information voxel. Hence, work aims develop method based finite element basis address above shortcomings. From reconstruction side, adjustable mask developed suppress artifacts speed up reconstruction. Both simulative experimental studies have been designed...
In this paper, we propose a directional wavelet approachto remove images of interfering strokes coming from theback historical handwritten document due to seepingof ink during long period storage. Our previous workrequired mapping both sides the in orderto identify be eliminated. Perfectmapping, however, is difficult skews,differing resolutions, non-availability reverseside and warped pages scanning. The newapproach does not require double-sided butinstead uses transformto distinguish...
Wavelet denoising is a commonly used method in the field of image algorithms, based on analysis characteristics estimated wavelet coefficients threshold and traditional soft hard method, light discontinuity fixed deviation threshold, non-differentiable compromise algorithm, algorithm put forward which continuous differentiable variable value deviation, experimental results show that this has better effect good practical value.
A remote multiplexed methane sensor system taking advantage of low cost 1.33 1&mgr;m SLD is demonstrated. it has long time stabilization, immunize from the influence temperature changing. Reference light adopted in to reduce affection attenuation caused by distance transmission fiber and drift output power.
