This work focuses on developing a novel adsorbent for CO2 capture, by coating polyethylenimine (PEI) glass fiber matrix and using epichlorohydrin (ECH) as cross-linking agent. The physicochemical properties of the fibrous were characterized. adsorption capacity was evaluated. Factors that affect studied. experimental results show this PEI exhibits much higher compared with another prepared in our previous work, which employed epoxy resin A high 4.12 mmol CO2/g obtained at 30 degrees C, equal...

Many colobine species—including the endangered Guizhou snub‐nosed monkey ( Rhinopithecus brelichi ) are difficult to maintain in captivity and frequently exhibit gastrointestinal (GI) problems. GI problems commonly linked alterations gut microbiota, which lead us examine microbial communities of wild captive R. . We used high‐throughput sequencing 16S rRNA gene compare microbiota N = 7) 8) brelichi. Wild monkeys exhibited increased diversity based on Chao1 but not Shannon metric greater...

Elastic optical network (EON) is a promising technology for the next generation of transport network. Routing, modulation and spectrum assignment one key issues in EON. In problem, constraints continuity contiguity must be satisfied. this paper, we propose policy named minimizing sum weighted resource reductions (min ΣwΔR) algorithm. The algorithm includes three contributions:1) concept reduction (ΔR) defined to measure variation idle resources path when block assigned connection request,...

Currently, exosomes derived from Cancer-associated fibroblast (CAF) have reportedly been involved in regulating hepatocellular carcinoma (HCC) tumour microenvironment (TME). LIM domain and actin binding 1 (LIMA1) is an actin-binding protein that controlling the biological behaviour progression of specific solid tumours. We aimed to determine effect LIMA1 exosome-associated miR-20a-5p HCC development. expression levels were examined by real-time quantitative PCR (qRT-PCR), western blotting or...

With the widespread application of Industrial Internet Things (IIoT) technology in industry, security threats are also increasing. To ensure safe sharing resources IIoT, this paper proposes a data model based on privacy protection (DSS-PP) for blockchain-enabled IIoT. Compared with previous works, DSS-PP has obvious advantages several important aspects: (1) In process identity authentication, it protects users' personal information by using authentication hidden attributes; (2) encrypted...

Abstract In the process of electrochemical ammonia synthesis using an aqueous solution as electrolyte, most protons will preferentially compete for electrons hydrogen generation. Herein, carbon cloth loaded with Nano‐Fe was used cathode, and a K 3 PO 4 electrolyte. The reduction N 2 to NH investigated. It found that electrolyte had obvious promotion effect on efficiency compared other electrolytes. confirmed phosphorus potassium synergistic efficiency. + can effectively prevent H from...

Deep neural networks are extremely vulnerable to attacks and threats from adversarial examples. These examples deliberately crafted by attackers can easily fool classification models adding imperceptibly tiny perturbations on clean images. This brings a great challenge image security for deep learning. Therefore, studying designing attack algorithms generating is essential building robust models. Moreover, transferable in that they mislead multiple different classifiers across makes...

Abstract We successfully prepared a novel fibrous adsorbent for carbon dioxide (CO 2 ) capture by coating polyethylenimine (PEI) on glass fiber matrix, using epoxy resin (EP) as crosslinking agent. The physicochemical properties of the adsorbents were characterized in terms Fourier transform infrared spectrometry and thermogravimetric analysis. Factors that affected adsorption capacity studied, including agent dosage, weight, moisture, temperature, CO concentration simulated flue gas....

Evidence has suggested the potential of tumor-educated platelets as a biomarker trove for cancer diagnostics, but difficulty in isolation limits its application. Since most circulating RNAs are derived from platelets, change RNA profile may lead to altered expression serum. Here, we identified panel platelet-associated long non-coding (lncRNAs) and evaluated diagnostic capacity serum colorectal (CRC) patients. Four lncRNAs, LNCAROD, SNHG20, LINC00534, TSPOAP-AS1, were upregulated both CRC A...
