Published: July 2020

Abstract
In recent years, electronic devices have been found everywhere in our lives, and many public places now offer free charging devices that are convenient for people to use. This paper studies the changing rules and future development trends of free charging demand and cost in public places, and gives a concrete model for calculating the cost and demand function of power resources in various occasions. For the first problem, we first found the use of power resources in the past ten years, and then described the trend of the free charging power demand in public places through a visual method. Then we introduce a time series model to predict the future demand of power resources, and use the data from 2000 to 2018 to predict the trend of power demand in 2019-2025. It can be seen that electricity consumption will continue to increase in the next few years, and the trend is more obvious than before. For question two, we first considered the cost of free charging in public. Since the free charging in public areas is somewhat similar to shared charging devices, we used the first question model to predict the cost of sharing charging devices in the coming week. Demand trends, by introducing parameters such as average device charging power, number of devices, and number of outlets, we established a power cost model and discussed the scope and scope of these costs. For the third problem, we revised the second question based on the parameters of different types of public places such as shopping centers, cafes, schools, etc., and constructed different cost models for calculation, and analyzed the models for different public places. The scope and strategy of the parameters. In response to question four, we have proposed measures to reduce the cost of energy use in public places from the perspective of the government and the public. It also analyzes the characteristics of free charging in schools and shopping malls, and finds measures to reduce energy consumption in public places in both cases. In response to question five, we wrote an article for the school newspaper about the electricity consumption in China in recent years and the measures to reduce the cost of electricity, and called on everyone to save electricity.

Abstract
Through pot experiments, the changes of soil total nitrogen, available potassium, available phosphorus, organic matter, and pH, and the contents of heavy metals in the tested soils before and after planting were analyzed. The result showed that: Compared to before planting, the soil total nitrogen, organic matter, available phosphorus, and available potassium decreased in turn. The total nitrogen decline of soybean soil was the largest, and the organic matter decline of tomato soil was the largest. The decrease of soil Cd and Cr is obvious, Pb is the second, and the decrease of other heavy metals is less than 10%. The overall decline in heavy metals in tomato soil was the largest, followed by clover, and soybean the smallest. Correlation analysis showed that soil total nitrogen and organic matter were significantly positively correlated with Cd, and available potassium was significantly positively correlated with Cr. Increasing soil nutrient content can promote the effect of plants on soil heavy metal remediation.

Published: July 2020

Abstract
The coating process is the main source of VOCs emissions in the aluminium profile industry. The electrophoretic coating process is a surface processing method widely used by aluminium profile companies. However, the electrophoretic coating process generates a large amount of exhaust gas, and the main component of the exhaust gas is VOCs. This paper combined with the monitoring of the exhaust gas treatment project of an electrophoresis coating workshop of a large aluminium profile company, and found that the main component is xylene. The exhaust gas treatment process uses “activated carbon adsorption + spray absorption” and more than 97% of emissions could be achieved.

Published: July 2020

Abstract
Metallic catalysts have presented high activity for the degradation of pollutants. However, the inevitable metal leaching would lead to secondary pollution, which hinders the development of metallic catalysts for water treatment. Membrane technology would be an effective way to conquer this, especially hollow fibre membrane with numerous micro-pores and high surface area per unit volume. The good recoverability and stable repeatability proved that the ceramic hollow fibre membrane would be a promising form of metallic catalysts for aqueous phase reaction.

Effects of zeolite and chicken manure on the growth of soybean and rapeseed
Authors: Xu Yan , Li Juan , Guo Zhen , Hua Dongwen 
Published: July 2020

Abstract
Zeolite, chicken manure and their mixtures were added to the soil in different proportions, and their effects on the growth of soybean and rapeseed were studied through pot experiments. The results showed that the addition of zeolite, chicken manure, or a mixture (1:1) all contributed to the plant height and fresh weight of soybean and rapeseed compared to CK treatment, but the plant height was greatly affected by the growth cycle. The weight gradually increases with the addition ratio. After the two are added in a 1:1 ratio, the advantages of plant height and fresh weight of soybean and rapeseed are more significant. The SPAD of soybean increased with the growth period, while the SPAD of rapeseed decreased significantly during the maturity period. The SPAD of both was greatly affected by the growth cycle, and the effects of each treatment were less. To sum up, in this experiment, the mixed ratio of zeolite and chicken manure can be used as a better soil improvement material, and the addition ratio of 20% is better.

Authors: Zhang Huihui , Liu Yanjia , Yuan Juntao , Zhu Ming , Chen Jie , Wang Zhihua 
Published: July 2020

Abstract
The electrodeposition of (Co,Mn)3O4 spinel precursor layers has emerged as a new method to prepare metallic interconnect coatings for solid oxide fuel cells (SOFCs). (Co,Mn)3O4 spinel films can be obtained via the oxidative heat treatment of an electrodeposited Co-Mn alloy layer. Herein, the effects of sandblasting stainless-steel substrates on the electrodeposition of the Co-Mn alloy were investigated. Sandblasting increased Co content in Co-Mn alloy, decreased the onset time of nucleation, and lead to surface nanocrystallization. Furthermore, sandblasting the substrate prevented the formation of the metal hydroxide interlayer, accelerated interdiffusion, and improved the adhesion of the (Co,Mn)3O4 spinel coatings.
Scanning probe lithography on calixarene towards single-digit nanometer fabrication
Authors: Kaestner Marcus , Rangelow Ivo W 
Published: July 2020

Abstract
Cost effective patterning based on scanning probe nanolithography (SPL) has the potential for electronic and optical nano-device manufacturing and other nanotechnological applications. One of the fundamental advantages of SPL is its capability for patterning and imaging employing the same probe. This is achieved with self-sensing and self-actuating cantilevers, also known as ‘active’ cantilevers. Here we used active cantilevers to demonstrate a novel path towards single digit nanoscale patterning by employing a low energy (<100 eV) electron exposure to thin films of molecular resist. By tuning the electron energies to the lithographically relevant chemical resist transformations, the interaction volumes can be highly localized. This method allows for greater control over spatially confined lithography and enhances sensitivity. We found that at low electron energies, the exposure in ambient conditions required approximately 10 electrons per single calixarene molecule to induce a crosslinking event. The sensitivity was 80-times greater than a classical electron beam exposure at 30 keV. By operating the electro-exposure process in ambient conditions a novel lithographic reaction scheme based on a direct ablation of resist material (positive tone) is presented.

is being varied, thus allowing the unification of vectors, matrices and tensors in single mathematical structures. This technique is applied to construct warped models in the passage from supergravity in 10 or 11-dimensional spacetimes to four-dimensional ones. We also show how nonlinear embeddings can be used to connect cellular automata (CAs) to coupled map lattices (CMLs) and to nonlinear partial differential equations, deriving a class of nonlinear diffusion equations. Finally, by means of nonlinear embeddings we introduce CA connections, a class of CMLs that connect any two arbitrary CAs in the limits κ → 0 and κ → ∞ of the embedding.

Abstract

Objectives
We report a rare case of B-lymphoblastic lymphoma (B-LBL) and low-grade follicular lymphoma (FL) identified concurrently in biopsies from different sites at the initial diagnosis in a 39-year-old man. The clonal relationship between the 2 histologic subtypes was investigated.

Methods
A diagnosis of FL grade 1/2 (low grade) was made by bone marrow (BM) biopsy. B-LBL was identified in biopsies from the testis and pancreas. Cytogenetic and molecular analyses were performed to investigate their clonal relationship.

Results
Interphase fluorescence in situ hybridization analyses and G-banding karyotype analyses identified the BCL2-IGH and MYC-IGH translocation in tumor cells from both the BM and testis. The tumor cells from the BM and testis shared the same IGH VDJ usage and a high degree of somatic mutations. These findings suggest that acquisition of MYC gene rearrangement is a critical event for lymphoblastic transformation of FL. Of note, the presence of intraclonal diversity in the B-LBL sample further suggests an earlier or concurrent event of MYC translocation than the somatic IGH mutation in the germinal center and the dedifferentiation of lymphoma cells to a precursor stage of B-cell development.

Conclusions
B-lymphoblastic transformation of FL can occur with MYC gene rearrangement.

Published: July 2020

Abstract
Hypertensive disorders of pregnancy (HDP) are a leading cause of severe maternal morbidity (SMM), yet mediation by cesarean delivery is largely unexplored. We investigated the association between HDP and SMM in a cohort of deliveries at a safety-net institution in Atlanta, Georgia, during 2016–2018. Using multivariable generalized linear models, we estimated adjusted risk differences, adjusted risk ratios, and 95% confidence intervals for the association between HDP and SMM. We examined interactions with cesarean delivery and used mediation analysis with 4-way decomposition to estimate excess relative risks. Among 3,723 deliveries, the SMM rate for women with and without HDP was 124.4 per 1,000 and 52.0 per 1,000, respectively. The adjusted risk ratio for the total effect of HDP on SMM was 2.55 (95% confidence interval (CI): 2.15, 3.39). Approximately 55.2% (95% CI: 25.7, 68.5) of excess relative risk was due to neither interaction nor mediation, 24.9% (95% CI: 15.4, 50.0) was due to interaction between HDP and cesarean delivery, 9.6% (95% CI: 3.4, 15.2) was due to mediation, and 10.3% (95% CI: 5.4, 20.3) was due to mediation and interaction. HDP are a potentially modifiable risk factor for SMM; implementing evidence-based interventions for the prevention and treatment of HDP is critical for reducing SMM risk.
SASS6 promotes proliferation of esophageal squamous carcinoma cells by inhibiting the p53 signaling pathway

Published: July 2020

Abstract
SASS6 encodes for the Homo sapiens SAS-6 centriolar assembly protein and is important for proper centrosome formation. Although centrosomes are amplified in a wide variety of tumor types, abnormally high SASS6 expression had previously only been identified in colon cancer. Moreover, the role of SASS6 in esophageal squamous cell carcinoma (ESCC) pathogenesis has not yet been elucidated. The aim of this study was to investigate the role and mechanisms of SASS6 in ESCC. In this study, we found that the mRNA and protein levels of SASS6 were increased in human ESCC samples. In addition, SASS6 protein expression was associated with the esophageal cancer stage and negatively affected survival of patients with ESCC. Furthermore, silencing of SASS6 inhibited cell growth and promoted apoptosis of ESCC cells in vitro and inhibited xenograft tumor formation in vivo. A genetic cluster and pathway analysis showed that SASS6 regulated the p53 signaling pathway. Western blot demonstrated that CCND2, GADD45A and EIF4EBP1 protein expression decreased and that TP53 protein expression increased after the knockdown of SASS6 in ESCC cells. Therefore, SASS6 promoted the proliferation of esophageal cancer by inhibiting the p53 signaling pathway. SASS6 has potential as a novel tumor marker and a therapeutic target for ESCC.
