Authors: Handoko Eko Yuli , Naibaho Loly Kurnia , Saptarini Dian , Yuwono  
Published: May 2021

Abstract
Sea level rise is one of the issues that are on the highlight today. Seawater that is in direct contact with the coastal area makes the region vulnerable to the environment. The Java Sea in Indonesia with a wide enough coverage will have many impacts on the coastal areas if there is an increase in sea level. For these observations, a sea-level anomaly (SLA) is calculated to understand sea level and its changes over time. SLA calculations use data from Cryosat-2 Satellite. Cryosat-2 is an altimetry satellite that was designed for the ice sheet observation mission and oceanography observation missions. This altimetry satellite has an excellent level of accuracy even though it does not have a microwave radiometer. This research is expected to know sea level variability of the Java Sea surface from 2011 to 2019. Obtained based on linear regression of the Cryosat-2 SLA trend, the Java Sea has decreased by 27.9746 mm at a rate of -3.55 mm/year. It is caused by the phenomenon of El-Niño Southern Oscillation (correlation coefficient of the SLA and MEI detrended indicating indicates a strong but not unidirectional correlation. The higher the MEI index, the lower the SLA value will be in the Java Sea, a vice versa, and MEI detrended, indicating a strong but not unidirectional correlation. The higher the MEI index, the lower the SLA value will be in the Java Sea, and vice versa.

Authors: He Yifei 
Published: May 2021

Abstract
Magnesium alloy is an important engineering metal material, which has a series of excellent mechanical, chemical and physical properties. It is widely used in aerospace, advanced manufacturing, biomedical and other fields. In the processing and preparation of magnesium alloy, high temperature and large deformation treatment are usually introduced. The introduction of temperature and strain rate will lead to grain coarsening and dynamic recrystallization. Therefore, it is necessary to study the effects of high temperature and deformation on the grain evolution of magnesium alloys. Based on the Monte Carlo simulation method, the microstructure evolution of AZ31 magnesium alloy at different temperatures and strain rates was simulated and analyzed. The results show that high temperature is the main reason for grain growth, and increasing strain rate can promote recrystallization and refine grain size.

Authors: Mao Yuling , Wan Lu , Zhang Yuting 
Published: May 2021

Abstract
The article uses the product-level and industry-level data to empirically test the relationship between China’s import of wood forest products and the pollution discharge of forest products industry from 2003 to 2015. The results of the benchmark model show that the import of wood forest products has a significant role in reducing the pollution emission of forest products industry. Furthermore, taking the total factor productivity as the intermediary variable, it is found that the import of wood forest products can improve the total factor productivity, thus promoting the pollution emission reduction of forest products industry. In addition, from the perspective of different factor intensive products, the empirical results show that the capital and technology intensive and the labor-intensive have different positive effects on pollution reduction through the improvement of total factor productivity.

Published: May 2021

Abstract
Biofilter is the core unit of the recirculating aquaculture system(RAS), which is mainly to achieve in situ purification and restoration of water pollutants by enriching microorganisms on biofilters to form biofilms. To explore the changes and metabolic characteristics of microbial communities in the process of biofilm formation in the RAS under low-temperature environment, the 16S rRNA high-throughput sequencing was applied to analyze differences of the microbial composition and structural characteristics in the biofilm initiation group (I) and biofilm formation group(B), and the PICRUSt functional gene prediction method was used to predict the metabolic functions. Results of microbial diversity showed that the OTUs numbers, Shannon index and richness index increased significantly after bio-film formation(p<0.05). The Pcoa results indicated that the microbial community composition in group B was quite different compared with the group I. After the biofilm formation, the phylum Proteobacteria, Bacteroidota, Fusobacteriota, Patescibacteria and Verrucomicrobiota were the main dominant bacteria on the biofilter. The denitrifying bacteria, such as Comamonadaceae and Rhodobacteraceae as the dominant bacteria in group B. Meanwhile, the activities of bio-film microorganisms in metabolic aspects of Carbohydrate Metabolism, Energy Metabolism, Lipid Metabolism, Amino Acid Metabolism of Terpenoids and Polyketides and Enzyme Families were obviously enhanced(p <0.05).

Is core bacterial community more vulnerable to environmental changes in dammed river?
Authors: Zhu Shijun , Wen Chen , Xie Shanshan , Luo Xia 
Published: May 2021

Abstract
It is well known that dam construction has a potential to impact water quality, resulting other related changes on bacterial community structure and diversity. Yet, effects of dam construction on planktonic and sediment bacterial structure are much more fragmentary. Through sampling of water and sediments along a dammed river between winter and summer, bacterial community were investigated using Illumina high-throughput sequencing. Core bacterial community, including Proteobacteria (55.29%), Firmicutes (25.29%), Bacteroidetes (17.22%), Verrucomicrobia (1.27%) and Gemmatimonadetes (0.93%), were maintained among water and sediments and between seasons. Mantel test showed the core bacterial community was less sensitive to environmental variable. However, a few of dominant microbe, such as class Alphaproteobacteria and family Sphingomonadaceae in core community were still tightly correlated with physiochemical properties according to correlation analysis. Physiochemical characteristics in water and sediment were mainly affected by season fluctuations. Changes in sediment texture has been attributed to the dam construction. This study suggests a potential to detect possible biological indicators of human and natural pressures in riverine system.

Published: May 2021

Abstract
Graphene has been widely used in the form of micro-flakes to fabricate composite materials with enhanced mechanical properties. Due to the small size of the inclusions and their random orientation within the matrix, the superior mechanical properties of graphene cannot be fully exploited. Recently, attempts have been made to fabricate nanolaminate composites by interleaving large sheets of chemical vapor deposition (CVD) monolayer graphene between thin layers of polymer matrices. However, CVD graphene is inevitably accompanied by wrinkles that are formed in the synthesis process, and it remains unknown how the wrinkles affect the mechanical properties of graphene. Here, we employ Brillouin light spectroscopy to study the elastic moduli of CVD graphene by probing graphene/poly(methylmethacrylate) hybrid Bragg stacks at zero strain. We find the Young’s and shear moduli of the CVD graphene, which has wrinkles in the form of sharp elevations with a height of about 6 nm and a fullwidth at half maximum (FWHM) of ca. 30 nm, to be 680 ± 16 and 290 ± 10 GPa, respectively, with the former being about 30% lower than that of exfoliated, flat graphene. This work sheds light on the elastic properties of CVD graphene and provides a method that can be extended to studying the wrinkle-induced softening effect in other two-dimensional materials.

Published: May 2021

Abstract
We report a methodology to analyze data extracted from infrared images. These pictures show the lower limbs of a cohort of individuals belonging to, (1) voluntary controls and (2) patients diagnosed with diabetes mellitus type II. The analysis is presented in terms of Cross Entropy and temperature distributions; both using the associated thermal histograms. The temperature analysis is placed in terms of comparing the extreme values of dS/dQ, for controls and patients. In this analysis for the frontal view, the values of specificity and sensitivity calculated were 77.77% and 91.66%, respectively. For the back view, the specificity and sensitivity obtained were 88.8% and 83.3%, respectively. Instead of that, the cross-entropy analysis is placed in the modality of self-referencing. In this part of the study we obtained the coefficient of asymmetry and thermal response (ATR). The values of specificity and sensitivity for the ATR quotient in both cases were 83.3%. The results of both studies have a significant correlation with glucose (p < 0.01) and HbA1c (p < 0.01). It means that both approaches have statistical correspondence. By means of the Mann-Whitney U test, for independent samples, we get that the characteristic parameters we analyze can be differentiated among the populations of interest with a significance of p < 0.05. This suggests that both studies show consistency with the clinical diagnosis; exhibiting clear differences between control and patient groups.

Published: May 2021

Abstract

Introduction
Frailty is a disorder of multiple physiological systems impairing the capacity of the organism to cope with insult or stress. It is associated with poor outcomes after acute illness. Our aim was to study the impact of frailty on the functional outcome of patients with acute ischemic stroke (AIS) submitted to endovascular stroke treatment (EST).

Methods
We performed a retrospective study of patients with AIS of the anterior circulation submitted to EST between 2012 and 2017, based on a prospectively collected local registry of consecutive patients. The Hospital Frailty Risk Score (HFRS) at discharge was calculated for each patient. We compared groups of patients with and without favourable 3-month outcome after index AIS (modified Rankin Scale 0–2 and 3–6, respectively). A multivariable logistic regression model was used to identify variables independently associated with favourable 3-month outcome. Diagnostic test statistics were used to compare HFRS with other prognostic scores for AIS.

Results
We included 489 patients with median age 75.6 years (interquartile range [IQR] = 65.3–82.3) and median NIHSS 15 (IQR = 11–19). About 29.7% presented a high frailty risk (HFRS &gt;15 points). Patients with favourable 3-month outcome presented lower HFRS and lower prevalence of high frailty risk. High frailty risk was independently associated with decreased likelihood of favourable 3-month outcome (adjusted odds ratio = 0.48, 95% confidence interval = 0.26–0.89). Diagnostic performances of HFRS and other prognostic scores (THRIVE and PRE scores, SPAN-100 index) for outcome at 3-months were similar.

Discussion
Frailty is an independent predictor of outcome in AIS patients submitted to EST.

Abstract

Objectives
Salivary gland acinic cell carcinoma (AciCC) has recognizable cytomorphologic features that can overlap with benign and malignant entities, creating a diagnostic challenge. AciCC harbors a t(4;9) translocation increasing nuclear receptor subfamily 4 group A member 3 (NR4A3) expression, detectable by immunohistochemistry (IHC) on surgical resection (SR). NR4A3 IHC cytology data are limited. Here, we examine NR4A3 IHC on smears, cell blocks (CBs), and SRs of AciCC and its mimickers.

Methods
Our cohort comprised AciCC (including high-grade transformation), secretory carcinoma, mucoepidermoid carcinoma (MEC), Warthin tumor, pleomorphic adenoma (PA), cellular PA, carcinoma ex-PA, oncocytic carcinoma, oncocytoma, and nodular oncocytosis. NR4A3 IHC (Santa Cruz Biotechnology and Origene antibodies) was positive if more than 5% tumor cells showed nuclear staining.

Results
Among CBs, 90% of AciCC cases and none of the mimickers expressed NR4A3. Among SRs, 100% of AciCC cases showed diffuse NR4A3, whereas one high-grade MEC expressed focal NR4A3. Concordance was 95% with two antibody clones. Sensitivity, specificity, positive predictive value, and negative predictive value were 90%, 100%, 100%, and 94.7% for CBs and 100%, 98.8%, 92.3%, and 100% for SRs, respectively. NR4A3 immunostaining was demonstrable on smears from an AciCC case.

Conclusions
NR4A3 IHC can be a robust diagnostic tool to identify AciCC, especially for cytology specimens.

Abstract
Increasing evidences show the clinical significance of the interaction between hypoxia and immune in clear cell renal cell carcinoma (ccRCC) microenvironment. However, reliable prognostic signatures based on a combination of hypoxia and immune have not been well established. Moreover, many studies have only used RNA-seq profiles to screen the prognosis feature of ccRCC. Presently, there is no comprehensive analysis of multiomics data to mine a better one. Thus, we try and get it. First, t-SNE and ssGSEA analysis were used to establish tumor subtypes related to hypoxia-immune, and we investigated the hypoxia-immune–related differences in three types of genetic or epigenetic characteristics (gene expression profiles, somatic mutation, and DNA methylation) by analyzing the multiomics data from The Cancer Genome Atlas (TCGA) portal. Additionally, a four-step strategy based on lasso regression and Cox regression was used to construct a satisfying prognostic model, with average 1-year, 3-year and 5-year areas under the curve (AUCs) equal to 0.806, 0.776 and 0.837. Comparing it with other nine known prognostic biomarkers and clinical prognostic scoring algorithms, the multiomics-based signature performs better. Then, we verified the gene expression differences in two external databases (ICGC and SYSU cohorts). Next, eight hub genes were singled out and seven hub genes were validated as prognostic genes in SYSU cohort. Furthermore, it was indicated high-risk patients have a better response for immunotherapy in immunophenoscore (IPS) analysis and TIDE algorithm. Meanwhile, estimated by GDSC and cMAP database, the high-risk patients showed sensitive responses to six chemotherapy drugs and six candidate small-molecule drugs. In summary, the signature can accurately predict the prognosis of ccRCC and may shed light on the development of novel hypoxia-immune biomarkers and target therapy of ccRCC.
Estimation of genetic correlation with summary association statistics
Authors: Wang Jianqiao , Li Hongzhe 
Published: May 2021

SummaryGenome-wide association studies have identified thousands of genetic variants that are associated with complex traits. Many complex traits are shown to share genetic etiology. Although various genetic correlation measures and their estimators have been developed, rigorous statistical analysis of their properties, including their robustness to model assumptions, is still lacking. We develop a method of moments estimator of genetic correlation between two traits in the framework of high-dimensional linear models. We show that the genetic correlation defined based on the regression coefficients and the linkage disequilibrium matrix can be decomposed into both the pleiotropic effects and correlations due to linkage disequilibrium between the causal loci of the two traits. The proposed estimator can be computed from summary association statistics when the raw genotype data are not available. Theoretical properties of the estimator in terms of consistency and asymptotic normality are provided. The proposed estimator is closely related to the estimator from the linkage disequilibrium score regression. However, our analysis reveals that the linkage disequilibrium score regression method does not make full use of the linkage disequilibrium information, and its jackknife variance estimate can be biased when the model assumptions are violated. Simulations and real data analysis results show that the proposed estimator is more robust and has better interpretability than the linkage disequilibrium score regression method under different genetic architectures.
