[Prediction of PM Concentration in Dry Bulk Ports Using a Combined Deep Learning Model Considering Feature Meteorological Factors].

Accurate prediction of PM concentration is important for effectively managing PM exposure and mitigating health and economic risks posed to humans in dry bulk ports. However, accurately capturing the time-series nonlinear variation characteristics of PM concentration is challenging owing to the specific intensity of port operation activities and the influence of meteorological factors. To address such challenges, a novel combined deep learning model （CLAF） was proposed, merging cascaded convolutional neural networks （CNN）, long short-term memory （LSTM）, and an attention mechanism （AM）.

Long Noncoding RNA FGD5-AS1 Promotes Glioma Cell Proliferation, Migration and Invasion by Regulating wnt/β-Catenin Pathway.

Purpose: To investigate the specific function of long noncoding RNA FGD5 antisense RNA 1 (lncRNA FGD5-AS1) in glioma.

Materials And Methods: The level of FGD5-AS1 was detected in clinical samples and cell lines by qRT-PCR. Small interfering RNA (siRNA) of FGD5-AS1 or scramble siRNA was transfected into U87 cell lines to examine the role of FGD5-AS1 on glioma development.

The crucial roles of guest water in a biocompatible coordination network in the catalytic ring-opening polymerization of cyclic esters: a new mechanistic perspective.

The ring-opening polymerization (ROP) of cyclic esters/carbonates is a crucial approach for the synthesis of biocompatible and biodegradable polyesters. Even though numerous efficient ROP catalysts have been well established, their toxicity heavily limits the biomedical applications of polyester products. To solve the toxicity issues relating to ROP catalysts, we report herein a biocompatible coordination network, CZU-1, consisting of Zn(μ-O)(COO) secondary building units (SBUs), biomedicine-relevant organic linkers and guest water, which demonstrates high potential for use in the catalytic ROP synthesis of biomedicine-applicable polyesters.

Perfluoroadamantane and its negative ion.

As a general rule, saturated hydrocarbons are unable to bind an electron, i.e., their electron affinities are negative, but the corresponding perfluorinated molecules can have significant electron affinities, especially in the case of branched and ring systems.

Dissolved organic matter (DOM) in recycled leachate of bioreactor landfill.

Landfill leachate needs sufficient treatment before safe disposal. Bioreactor landfill technology could effectively degrade the organic matters in recirculated leachate, hence leaving a leachate stream of low biodegradability. This study characterized the dissolved organic matter (DOM) in the leachate from simulated bioreactor landfill columns with or without presence of trace oxygen.

The Perfluoroadamantyl Radicals C10F15 and Their Anions.

The optimized geometries, electron affinities, and harmonic vibrational frequencies of perfluoroadamantyl radicals (C10F15) have been obtained using four carefully calibrated density functional theory methods in conjunction with diffuse function augmented double-ζ plus polarization (DZP++) basis sets. There are two C10F15 isomers with close energies. With the DZP++ B3LYP method, the C3v isomer (1-C10F15) lies energetically above the Cs isomer (2-C10F15) by 0.
