Gas chromatography – tandem mass spectrometry (GC-MS/MS) using formic acid as a protective agent is reported for the determination of acrylic resin monomers in food contact packaging paper. The analytes were extracted by ethanol mixed with formic acid with 2-phenylethyl propionate as the internal standard. The extract was separated by a 6% cyanopropylbenzene-94% dimethylsiloxane ultra-inert chromatographic column and analyzed by GC-MS/MS in multiple reaction monitoring (MRM) mode. 13 acrylic resin monomers including acrylic acid, styrene,...

Chemical investigation of secondary metabolites of the deep-sea-derived Alcanivorax sp. SHA4 identified a new compound 1 which was antimycic acid (2)'s acetyl derivative, and 11 known compounds (2-12). Their structures were elucidated by extensive nuclear magnetic resonance and mass spectrometry spectroscopic analyses, and the absolute configuration of compound 1 was determined by Marfey's method. Bioactivity assays indicated that compounds 1 and 2 exhibited significant neuroprotective properties against glutamate-induced PC12 cell death in 0.02-0.31 μM.

A new species of Diatrype (Diatrypaceae, Xylariales), D. genheensis, is proposed based on a combination of morphological features and molecular evidence. Diatrype genheensis, from a fallen angiosperm branch in Inner Mongolia, is characterized by having 3–14 perithecia embedded within a stroma, polysporous asci and ascospores that are allantoid, slightly curved, aseptate and subhyaline. The phylogeny of Diatrypaceae was inferred from a combined dataset of ITS and β-tubulin sequences. The phylogenetic tree indicated that D. genheensis...

Backgrounds Zero-events studies frequently occur in systematic reviews of adverse events, which consist of an important source of evidence. We aimed to examine how evidence of zero-events studies was utilized in the meta-analyses of systematic reviews of adverse events. Methods We conducted a survey of systematic reviews published in two periods: January 1, 2015, to January 1, 2020, and January 1, 2008, to April 25, 2011. Databases were searched for systematic reviews that conducted at...

Fringe projection profilometry (FPP) has attracted wide attention in the optical 3D measurement field for its high resolution, high accuracy, simple system construction, etc. However, the inherent requirements of FPP's measurement speed and accuracy are contradictory. We adopt a 3+1 phase retrieval strategy combining phase shift and Hilbert transform algorithms to achieve high-speed, high-precision simultaneous measurements with only four binary fringe patterns. Furthermore, when using temporal phase unwrapping, fringe order errors (FOEs) are inevitable. Although...

Imaging through strongly scattering media remains a significant challenge in dynamic scattering scenes containing both moving objects and dynamic media. In order to avoid the errors introduced by speckle modulation and phase-retrieval algorithms in the existing studies, we utilize the dynamics of objects and media and put forward a recursion-driven bispectral imaging (ReDBI) framework here. Either a stationary object or a moving one hidden behind the dynamic media can be reconstructed accurately by ReDBI. We...

Manipulating the polarization state of terahertz waves is critical for terahertz communication systems. In this study, a terahertz band polarization conversion metasurface based on dislocation-induced anisotropy is proposed. Numerical simulation results revealed that the polarization conversion of orthogonal linearly polarized light, left and right circularly polarized light, linearly polarized light to circularly polarized light, and circularly polarized light to linearly polarized light can be realized. Furthermore, the simulation revealed that multifunctional polarization conversion can be...

In this work, Helmholtz-resonator quartz-enhanced photoacoustic spectroscopy (HR-QEPAS) was developed for trace gas sensing. A pair of Helmholtz resonators with high-order resonance frequency were designed and coupled with the quartz tuning fork (QTF). Detailed theoretical analysis and experimental research were carried out to optimize the HR-QEPAS performance. As proof-of-concept experiment, the water vapor in the ambient air was detected using a 1.39 μm near-infrared laser diode. Benefiting from the acoustic filtering of the Helmholtz resonance,...

This study was to conduct a meta-analysis to explore the impact of gross total resection (GTR) and subtotal resection (STR) on survival outcomes in glioma patients. Relevant studies were searched in multiple databases from the available date of inception through 30 December 2021. The weighted mean differences (WMDs), relative risks (RRs), or hazard ratios (HRs) with 95% confidence intervals (CIs) were used to access the effect of GTR versus STR treatments on the outcomes. The...

The performance of a mixture-based picosecond laser mirror (MPLM) coating, particularly the picosecond (ps) laser-induced damage threshold (LIDT), is investigated. Two types of 1053 nm ps laser mirror coatings are deposited using electron-beam evaporation: an MPLM coating consists of alternating layers of the HfO₂-Al₂O₃ mixture and SiO₂, and a traditional picosecond laser mirror (TPLM) coating consists of alternating layers of HfO₂ and SiO₂. Comparative studies on the optical, microstructural and mechanical properties, and LIDT are...
