Two-dimensional materials have attracted great attention because of their ultra-thin atomic layer thickness and high carrier mobility. In this work, we investigated the electronic transport of in-plane (IP) heterojunction based on Cu/Blue Phosphorus (BlueP), and the results suggest the metallization at the IP Cu/BlueP contact interface and a small Schottky barrier. Then, we investigated the performance of 5.1 nm IP BlueP Schottky barrier field-effect transistors (SBFET) with different dielectrics (SiO2, Al2O3, Y2O3, and La2O3) using quantum transport simulations. The results show that IP BlueP SBFETs with four dielectrics satisfy the off-state requirement of the International Technology Roadmap for Semiconductors (ITRS) for the high-performance (HP) device. However, the on-state current of only IP BlueP SBFET with La2O3 satisfies the requirements of ITRS. This will provide a reference for designing BlueP SBFETs.

NEDD4L suppresses PD-L1 expression and enhances anti-tumor immune response in A549 cells

Background: Non-small cell lung cancer (NSCLC) poses a salient threat to public health. E3 ubiquitin ligase commonly functions as an anti-tumor role. Objective: This study probed the effect of E3 ligase NEDD4L on A549 cells. Methods: NEDD4L expression in NSCLC and its correlation with NSCLC patient's prognosis were predicted and verified. PD-L1 protein level was measured, and the correlation between NEDD4L and PD-L1 was analyzed. The effects of NEDD4L overexpression on the binding of NEDD4L to PD-L1 and ubiquitination level of PD-L1 were examined. Xenograft tumor model was established in mice. The volume and weight of xenograft tumors were recorded. The proportion of CD8+ T cells and contents of IL-2 and INF-γ were detected. Results: NEDD4L expression was downregulated in NSCLC tissues and A549 cells, and correlated with poor prognosis of NSCLC patients. PD-L1 was upregulated in NSCLC and negatively correlated with NEDD4L. Overexpression of NEDD4L upregulated ubiquitination level of PD-L1 and reduced protein level of PD-L1. Overexpression of NEDD4L decreased tumor volume and weight and enhanced proportion of CD8+ T cells and contents of IL-2 and INF-γ. Conclusions: Collectively, overexpression of NEDD4L suppressed PD-L1 protein level through ubiquitination, thereby enhancing anti-tumor immune response and retarding NSCLC progression.

Stability of Hybrid Impulsive and Switching Stochastic Systems with Time-delay
Xuegang Tan,Bin Hu,Zhi-Hong Guan,Rui-Quan Liao,Jiang-Wen Xiao,Yuehua Huang 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.4
This paper investigates a model of hybrid impulsive and switching stochastic systems (HISSS) with time-delay. Several stability criteria, including the globally asymptotical and exponential stability criteria in the pth moment and mean square, are established by using Itô formula, a generalized switching Lyapunov functions and some relating techniques. Especially, a more general Lyapunov-Krasivskii functional is constructed, and it is observed that the mean square asymptotic and exponential stability conditions of HISSS are delay-dependent. A numerical example shows that the obtained stability results can reduce the conservativeness.

This paper presented an investigation into steel tubes encased high-strength concrete (STHC) composite walls, wherein steel tubes were embedded at the boundary elements of high-strength concrete walls. A series of cyclic loading tests was conducted to evaluate the failure pattern, hysteresis characteristics, load-bearing capacity, deformability, and strain distribution of STHC composite walls. The test results demonstrated that the bearing capacity and ductility of the STHC composite walls improved with the embedding of steel tubes at the boundary elements. An analytical method was then established to predict the flexural bearing capacity of the STHC composite walls, and the calculated results agreed well with the experimental values, with errors of less than 10%. Finally, a finite element modeling (FEM) was developed via the OpenSees program to analyze the mechanical performance of the STHC composite wall. The FEM was validated through test results; additionally, the influences of the axial load ratio, steel tube strength, and shear-span ratio on the mechanical properties of STHC composite walls were comprehensively investigated.

Tropical plant rubber tree (Hevea brasiliensis) is the sole source of commercial natural rubber and low-temperature stress is the most important limiting factor for its cultivation. To characterize the gene expression profiles of H. brasiliensis under the cold stress and discover the key cold stress-induced genes. Three cDNA libraries, CT (control), LT2 (cold treatment at 4 °C for 2 h) and LT24 (cold treatment at 4 °C for 24 h) were constructed for RNA sequencing (RNA-Seq) and gene expression profiling. Quantitative real time PCR (qRT-PCR) was conducted to validate the RNA-Seq and gene differentially expression results. A total of 1457 and 2328 differentially expressed genes (DEGs) in LT2 and LT24 compared with CT were respectively detected. Most significantly enriched KEGG pathways included flavonoid biosynthesis, phenylpropanoid biosynthesis, plant hormone signal transduction, cutin, suberine and wax biosynthesis, Pentose and glucuronate interconversions, phenylalanine metabolism and starch and sucrose metabolism. A total of 239 transcription factors (TFs) were differentially expressed following 2 h or/and 24 h of cold treatment. Cold-response transcription factor families included ARR-B, B3, BES1, bHLH, C2H, CO-like, Dof, ERF, FAR1, G2-like, GRAS, GRF, HD-ZIP, HSF, LBD, MIKC-MADS, M-type MADS, MYB, MYB-related, NAC, RAV, SRS, TALE, TCP, Trihelix, WOX, WRKY, YABBY and ZF-HD. The genome-wide transcriptional response of rubber tree to the cold treatments were determined and a large number of DEGs were characterized including 239 transcription factors, providing important clues for further elucidation of the mechanisms of cold stress responses in rubber tree.
