Authors: Xu Chongbang , Gao Xiaojing , Li Xuefeng , Zhang Kaishun
Published: November 2020

The thaumasite sulfate attack (TSA) on tunnel concrete structure has been reported increasingly in the past decades. Previous investigations on the formation of thaumasite were focused on identifying the deterioration products and reaction mechanisms, while the occurrence time of TSA on tunnel concrete structures was not reported. A highway tunnel exposed to TSA was reported in the present study. The development of tunnel diseases and results of experimental tests conducted in the tunnel and in the laboratory were analyzed to investigate the occurrence time of TSA on concrete. Results revealed that the thaumasite was formed in a range of 18 to 36 months after the construction of Dugongling tunnel. The preconditions for the formation of thaumasite on tunnel concrete structures are available in Shanxi Province, China, due to the special conditions of stratum lithology and climate. The compositions of corrosion products of lining concrete under TSA varied for site studies and for laboratory tests. Site investigations on TSA on tunnel lining concrete should be paid more attention in further research.

Published: November 2020

Background. Fuzheng Huayu recipe (FZHY) is an original Chinese patent medicine which was developed and marketed by our institute. It could markedly improve liver tissue inflammation and ameliorate hepatic fibrosis in the clinical study. The intrahepatic macrophages recruitment and polarization play an important role in the progress of liver inflammation and fibrosis. Whether FZHY exerted its antiliver fibrosis effects through regulating intrahepatic macrophages phenotypic ratios is still unknown. This study aims to explore the antifibrosis mechanism of FZHY on regulating the recruitment and polarization of intrahepatic macrophages. Methods. C57/B6 mice were used for the establishment of the CCl4‐induced mice liver fibrosis model. Liver inflammation and fibrosis were evaluated by HE and Sirius red staining, hydroxyproline assays, and biochemical tests. The levels of chemokines and inflammatory cytokines in liver tissue were measured by RNA‐Seq transcriptome analysis, western blot assay, RT‐qPCR, and immunofluorescence assay. The macrophages recruitment and phenotypic polarization were observed by flow cytometry. Results. FZHY significantly improved liver inflammation and reduced liver fibrosis degree. TNF signaling pathway, involved in macrophages recruitment and phenotypic polarization, was discovered by RNA‐Seq transcriptome analysis. In TNF signaling pathway, CCL2 expression was significantly decreased and CX3CL1 expression was significantly upregulated by FZHY in liver tissue and primary intrahepatic macrophages. The ratio of proinflammatory hepatic resident macrophage‐Kupffer cells (F4/80+CD11b−CD86+) was downregulated by FZHY, while the proportion of anti‐inflammatory Kupffer cells (F4/80+CD11b−CD206+) was upregulated. Meanwhile, the ratio of proinflammatory Ly6Chigh macrophages (F4/80+CD11b+Ly6Chigh) which were recruited from blood circulation by CCL2 was reduced by FZHY, while the ratio of restorative Ly6Clow macrophages (F4/80+CD11b+Ly6Clow) which were recruited from blood circulation or induced from Ly6Chigh macrophages polarization by CX3CL1 was significantly increased. Conclusions. FZHY could regulate the recruitment and polarization of intrahepatic macrophages via CCL2 and CX3CL1, so as to play its anti‐inflammation and antifibrosis pharmacological effects in the liver.

Published: November 2020

We study constant and variable fluid properties together to investigate their effect on MHD Powell–Eyring nanofluid flow with thermal radiation and heat generation over a variable thickness sheet. The similarity variables assist in having ordinary differential equations acquired from partial differential equations (PDEs). A novel numerical procedure, the simplified finite difference method (SFDM), is developed to calculate the physical solution. The SFDM described here is simple, efficient, and accurate. To highlight its accuracy, results of the SFDM are compared with the literature. The results obtained from the SFDM are compared with the published results from the literature. This gives a good agreed solution with each other. The velocity, temperature, and concentration distributions, when drawn at the same time for constant and variable physical features, are observed to be affected against incremental values of the flow variables. Furthermore, the impact of contributing flow variables on the skin friction coefficient (drag on the wall) and local Nusselt (heat transfer rate on the wall) and Sherwood numbers (mass transfer on the wall) is illustrated by data distributed in tables. The nondimensional skin friction coefficient experiences higher values for constant flow regimes especially in comparison with changing flow features.
Removal of Fluorescein Dye from Aqueous Solutions Using Natural and Chemically Treated Pine Sawdust
Authors: Al-Kadhi Nada S.
Published: November 2020

The various factors affecting the removal of fluorescein dye using sawdust from aqueous solutions such as time, initial concentration, pH, and temperature were studied. The optimal conditions for removing the FD are 1 g of sawdust at pH 3 and 120 min time of contact. Dye removal dropped from 93.42% to 80.04% with natural pine sawdust (NPS) and from 96.83% to 81.51% with synthetic pine sawdust (SPS) by increasing their concentration from 2 to 10 mg/L. Isotherm, kinetic, and thermodynamic models were applied for determining their constants. The results indicated that the FD removal equilibrium was effectively defined by the Langmuir, Freundlich, and Temkin models. Kinetic studies showed that the pseudo-second order was well suited for dye removal, and the internal diffusion process was by two steps. The thermodynamic parameter values suggested that FD removal were physical adsorption, exothermic, lower randomness, and spontaneous.
Posttranslational Modifications in Ferroptosis
Authors: Wei Xiang , Yi Xin , Zhu Xue-Hai , Jiang Ding-Sheng
Published: November 2020

Ferroptosis was first coined in 2012 to describe the form of regulated cell death (RCD) characterized by iron-dependent lipid peroxidation. To date, ferroptosis has been implicated in many diseases, such as carcinogenesis, degenerative diseases (e.g., Huntington’s, Alzheimer’s, and Parkinson’s diseases), ischemia-reperfusion injury, and cardiovascular diseases. Previous studies have identified numerous targets involved in ferroptosis; for example, acyl-CoA synthetase long-chain family member 4 (ACSL4) and p53 induce while glutathione peroxidase 4 (GPX4) and apoptosis-inducing factor mitochondria-associated 2 (AIFM2, also known as FSP1) inhibit ferroptosis. At least three major pathways (the glutathione-GPX4, FSP1-coenzyme Q10 (CoQ10), and GTP cyclohydrolase-1- (GCH1-) tetrahydrobiopterin (BH4) pathways) have been identified to participate in ferroptosis regulation. Recent advances have also highlighted the crucial roles of posttranslational modifications (PTMs) of proteins in ferroptosis. Here, we summarize the recently discovered knowledge regarding the mechanisms underlying ferroptosis, particularly the roles of PTMs in ferroptosis regulation.

Published: November 2020

Objective. The aim of this work was to validate the statistical significance and unidimensionality of the construct formed by the variables of the revised and short version of the Smartphone Addiction Scale (SAS-SV), adapted into Spanish, when applied to Mexican university students. Method. The questionnaires were administered to 244 students of Bachelor’s Degree in Administration of the Universidad Autónoma de San Luis Potosí, Mexico; 174 women and 70 men, aged 17 to 30 years, between August and December 2018. A confirmatory factor analysis was performed, and the parameters of the variables were checked by maximum likelihood and also by Bayesian analysis. The reliability of the instrument was verified through Cronbach’s alpha. As a final analysis, estimates of nonstandardized weights for the maximum likelihood method were compared against Bayesian a posteriori distribution estimates. Results. As a result, the model was found to adequately describe the sample data, presenting very small standard error estimates, and it was validated with Cronbach’s alpha of 0.885. In both Bayesian and maximum likelihood analysis, it is consistently evident that the construct is unidimensional. However, for the sample studied, it was observed that 3 of the variables did not reach a significant weight for the model. Conclusion. It concludes that the variables that measure smartphone addiction on the SAS-SV scale adapted to Spanish, indeed, form a unidimensional construct when applied to Mexican university students, which is consistent with results from previous studies. However, it is identified necessary to conduct further studies, in order to explain the low significance obtained for 3 variables of the model.
Identification and Implications of Trimethyl-n-Alkylbenzenes in Marine Oils from the Deep Tarim Basin
Authors: Jia Wanglu , Huang Yangen , Xiao Zhongyao , Peng Ping’an
Published: November 2020

The source of marine oils from the deep Tarim Basin is still in debate due to several alteration processes of source indicators. A series of trimethyl-alkylbenzenes has been detected in marine oils from this old, composite basin, besides the reported aryl isoprenoids with 2,3,6-trimethyl substitution (AIPs). They are characterized by regular gas chromatography elution pattern, which is similar to that of n-alkylbenzenes, and suggest a strong possibility of n-alkyl side chains. C15 trimethyl-n-alkylbenzenes were synthesized by Friedel–Crafts acylation of trimethylbenzene isomers to determine their structures. Based on the chromatography and mass spectra data and the coinjection of synthesized compounds, this series of compounds has been assigned as the 2,4,5-trimethyl-n-alkylbenzenes that coeluted with 2,3,5-trimethyl-n-alkylbenzenes, and other trimethyl-n-alkylbenzene isomers were also detected. This series of trimethyl-n-alkylbenzene (AAs) shows much higher relative abundances in light and waxy oils than in normal and heavy oils, which is opposite to the variation in relative abundances of aryl isoprenoids. The ratios of these trimethyl-n-alkylbenzenes to the aryl isoprenoids (AA/AIP ratio) generally show a good correlation with the maturity indicators for most of studied oils despite of some outliers (mainly condensates). The pyrolysis of asphaltenes has confirmed these trends. These results support an important control of thermal stress on the molecular compositions of marine oils from the deep Tarim Basin, besides other secondary alteration processes (such as oil mixing and migration fractionation, among others). These factors should be given a full consideration for the source determination of deep and ultradeep oils.
Research on China’s Regional Carbon Emission Quota Allocation in 2030 under the Constraint of Carbon Intensity
Authors: Zhang Yuan
Published: November 2020

To achieve the goal of carbon dioxide emission reduction in 2030 promised to the United Nations, China unified the Carbon Trading System (CTS) in 2017 since carbon dioxide quota allocation is one of the core issues of carbon trading. It is imperative to establish a flexible carbon quota allocation system based on the unbalanced characteristics of resource endowment and economic development in different regions. Unlike previous distribution research, this paper considers five principles, which are fairness principle, efficiency principle, feasibility principle, development principle, and innovation principle. The maximum deviation method is used to research the carbon emission quota allocation in 30 provinces of China, and the results are compared with those under the single principle and the information entropy method. The results reveal that the distribution under the single principle is severely unbalanced, making the region have a strong sense of relative deprivation. The maximum deviation method is better than the information entropy method to achieve carbon intensity by 2030. It is also conducive to promote the coordinated development of the regional economy, narrow the poverty gap, and achieve sustainable development.

Published: November 2020

In this paper, first, we study mean-absolute deviation (MAD) portfolio optimization model with cardinality constraints, short selling, and risk-neutral interest rate. Then, in order to insure the investment against unfavorable outcomes, an extension of MAD model that includes options is considered. Moreover, since the data in financial models usually involve uncertainties, we apply robust optimization to the MAD model with options. Finally, a data set of S&P index is used to compare the effectiveness of options in the models in terms of returns and Sharpe ratios.
Experimental Study on Desorption Characteristics of Coalbed Methane under Variable Loading and Temperature in Deep and High Geothermal Mine

Published: November 2020

Due to the influence of deep high stress, geothermal heat, and other factors, the law of desorption of methane in coal seams is more complicated in the process of mining deep coal seams, which is prone to methane over‐limit, coal and gas outburst, and other accidents. In order to study the desorption characteristics of coalbed methane under different loading and temperature conditions, the desorption tests at different deformation stages of coal containing methane were carried out in the process of loading‐adsorption‐desorption‐reloading until the coal sample was destroyed by using the seepage‐adsorption‐desorption test system on coal and rock mass, and the test programs were different combinations of gas pressure 1.2 MPa, two kinds of confining pressure, and three kinds of temperature. The results show that the cumulative methane desorption amount corresponding to each deformation stage presents a convex parabolic increase trend with the increase in desorption time, while the desorption rate presents a power function decay trend. Under the condition of the same desorption time, the cumulative methane desorption amount from large to small is residual deformation stage, compaction stage, near the peak stress, plastic deformation stage, and elastic deformation stage. Under the same confining pressure, temperature, and methane pressure, the maximum desorption rate from large to small is residual deformation stage, near the peak stress, plastic deformation stage, compaction stage, and elastic deformation stage. The desorption and diffusion of methane are promoted under the higher temperature and lower confining pressure, which presents a certain mechanism of promoting desorption. The thermal movement of methane molecules is intensified with the increase in temperature, and the adsorption effect between methane molecules and the molecules at the surface of the coal is weakened. The cumulative methane desorption amount and the maximum desorption rate increase with the increase in temperature. The cumulative methane desorption in the residual deformation stage is obviously greater than that in other deformation stages. The increase in confining pressure inhibits the development and expansion of pore fractures in raw coal specimen and hinders the increase in the effective desorption surface area. The cumulative methane desorption amount and the maximum desorption rate decrease with the increase in confining pressure.

Published: November 2020

Purpose. To evaluate the difference in macular choroidal thickness and volume between patients with pseudoexfoliative glaucoma (PXG), patients with pseudoexfoliative syndrome (PEX), and normal controls. Methods. This case-control study included 49 PXG patients (group A), 33 PEX patients (group B), and 42 sex-, age-, and axial length-matched healthy volunteer eyes (group C). The macular choroidal thickness and volume of all subjects studied were measured by enhanced depth imaging optical coherence tomography. Results. The average macular (AM) choroidal thickness was 170.79 ± 50.18 μm, 184.65 ± 57.54 μm, and 206.46 ± 48.90 μm, and the average volume was 0.52 ± 0.15 μm3, 0.56 ± 0.17 μm3, and 0.63 ± 0.15 μm3 in groups A, B, and C, respectively. The macular choroidal thickness, the volumes of various macular regions, and the average choroidal thickness and volume in group A were lower than those in group C (all

P
<
0.05

). There were no significant differences in the macular choroidal thickness, volumes of various macular regions, or average choroidal thickness or volume between group A and B (all

P
>
0.05

). The macular choroidal thickness and volume of the TIM and SOM in group B were lower than those in group C (

P
<
0.05

). There was no association between the macular choroidal thickness of various macular regions and visual field mean defect (MD) in group A (all

P
>
0.05

). Conclusion. The macular choroidal thickness in patients with PXG or PEX (TIM and SOM) is thinner than that in normal subjects. The macular choroidal thickness in patients with PXG is not significantly different from that in patients with PEX. The role of macular choroidal thickness changes in the glaucomatous damage of patients with PXG is still unclear.
Estimating Network Flowing over Edges by Recursive Network Embedding
Authors: Yu Liqun , Wang Hongqi , Mo Haoran
Published: November 2020

In this paper, we propose a novel semisupervised learning framework to learn the flows of edges over a graph. Given the flow values of the labeled edges, the task of this paper is to learn the unknown flow values of the remaining unlabeled edges. To this end, we introduce a value amount hold by each node and impose that the amount of values flowing from the conjunctive edges of each node to be consistent with the node’s own value. We propose to embed the nodes to a continuous vector space so that the embedding vector of each node can be reconstructed from its neighbors by a recursive neural network model, linear normalized long short-term memory. Moreover, we argue that the value of each node is also embedded in the embedding vectors of its neighbors, thus propose to approximate the node value from the output of the neighborhood recursive network. We build a unified learning framework by formulating a minimization problem. To construct the learning problem, we build three subproblems of minimization: (1) the embedding error of each node from the recursive network, (2) the loss of the construction for the amount of value of each node, and (3) the difference between the value amount of each node and the estimated value from the edge flows. We develop an iterative algorithm to learn the node embeddings, edge flows, and node values jointly. We perform experiments based on the datasets of some network data, including the transportation network and innovation. The experimental results indicate that our algorithm is more effective than the state-of-the-arts.

Highly energetic proton/electron beam fixed-target experiments extend an opportunity to probe the sub-GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub-GeV leptophobic dark matter, i.e., this dark matter barely couples with the leptons. Baryon number gauge theory can predict the existence of leptophobic cold dark matter particle candidates.

Who Built Old St Peter’s? The Evidence of the Inscriptions and Mosaics
Authors: Logan Alastair
Published: November 2020

Old St Peter’s in Rome, according to the sixth-century Liber Pontificalis, was founded by Constantine (306–337), a claim accepted by most scholars who appeal to a variety of evidence. This paper will challenge this, focusing on the inscriptional and mosaic evidence and developing the arguments of Glen Bowersock and Alastair Logan that it was not constructed by Constantine at all but by one of his sons, in all likelihood Constans (337–350). It will argue that he began it in the late 340s as a five-aisled cemeterial basilica which Constantius II (337–361) completed in the late 350s, adding the apse mosaic. The paper will argue for the fundamental significance of two anonymous inscriptions and claim that the key evidence cited has not properly included one of them and in fact reflects the growing influence of legends about Constantine and Silvester.
“Learn to Restrain Your Mouth”: Alchemical Rumours and their Historiographical Afterlives
Authors: Prinke Rafał T. , Zuber Mike A.
Published: November 2020

From around 1700 onwards, a number of sensationalist claims regarding adepts of
the sixteenth and early seventeenth centuries began to appear in alchemical
literature. They eventually made their way into standard works of historiography
and continue to be repeated as factual. Yet the source for these rumours, a poem
attributed to Martinus de Delle, supposedly a chamberlain of Emperor Rudolf II,
has largely escaped scrutiny. The only surviving manuscript version currently
known is here edited and translated in full for the first time. In the
introductory essay, we call into question the existence of De Delle. Through
scrutiny of the portrayals of alchemists within the poem, we propose that the
author may have been an assayer in Prague. We then draw attention to the roles
and effects of rumours within both the history and historiography of alchemy and
argue for the importance of taking alchemical gossip seriously.
Remaking the Catholic Church in Santo Domingo
Authors: Keane-Dawes Antony Wayne
Published: November 2020

In 1824, the Haitian government passed a series of laws that secularized the Catholic Church’s lands in Santo Domingo and placed this religious institution under state control. Using correspondences, pamphlets, and petitions, this article argues that Haitian reforms of the Church in Santo Domingo created a new power dynamic that incorporated local communities with these secular and religious institutions. In doing so, this literature brings together two literatures that rarely speak to one another: the impact of the Haitian Unification on the Church in Santo Domingo and Haitian diplomatic negotiations over sovereignty in the Atlantic world. This article will discuss how different relationships between Church and state in Santo Domingo and Haiti resulted in conflict after Haiti’s annexation in 1822. Next, it will focus on the clerics’ responses to Haitian rule that includes the consequences of the 1824 secularization law. Finally, it will examine the impact of Haitian reforms on local communities particularly their relationships with their priests.
Perceived Congruency in Audiovisual Stimuli Consisting of Gabor Patches and AM and FM Tones
Authors: Postnova Natalia , Nakajima Yoshitaka , Ueda Kazuo , Remijn Gerard B.
Published: November 2020

Experiments that focus on how humans perceive temporal, spatial or synaesthetic congruency in audiovisual sensory information have often employed stimuli consisting of a Gabor patch and an amplitude (AM) or frequency (FM)-modulated sound. Introducing similarity between the static and dynamic features of the Gabor patch and the (carrier) frequency or modulation frequency of the sound is often assumed to be effective enough to induce congruency. However, comparative empirical data on perceived congruency of various stimulus parameters are not readily available, and in particular with respect to sound modulation, it is still not clear which type (AM or FM) induces perceived congruency best in tandem with various patch parameters. In two experiments, we examined Gabor patches of various spatial frequencies with flickering (2, 3 and 4 flickers/s) or drifting (0.5, 1.0 and 1.5 degrees/s) gratings in combinations with AM or FM tones of 2-, 3- and 4-Hz modulation and 500-, 1000- and 2000-Hz carrier frequencies. Perceived congruency ratings were obtained by asking participants to rate stimulus (in)congruency from 1 (incongruent) to 7 (congruent). The data showed that varying the spatial frequency of the Gabor patch and the carrier frequency of the modulated tone had comparatively little impact on perceived congruency. Similar to previous findings, similarity between the temporal frequency of the Gabor patch and the modulated tone effectively promoted perceived congruency. Furthermore, direct comparisons convincingly showed that AM tones in combination with flickering Gabor patches received significantly higher audiovisual congruency ratings compared to FM tones.
Translingual Affairs of World Literature
Authors: De Donno Fabrizio
Published: November 2020

This essay explores a number of texts of the exophonic, or non-native literary production, respectively in Italian and German, of translingual authors Jhumpa Lahiri and Yoko Tawada. While the paper looks at how their dominant languages, respectively English and Japanese, continue to play a role in these writers’ non-native production, it focuses on the different approaches the two authors adopt to translingualism and the “linguistic family romance” metaphor, which they equally employ in highly imaginative ways in order to address both their condition of rootlessness and their attitudes to the notion of “mother tongue.” The essay argues that while Lahiri seems to remain a writer that does not contaminate languages (she is a writer in English, a writer in Italian, and a translator of Italian literature into English), Tawada brings German and Japanese together and dwells on the space of contamination between them in her production in German (and Japanese).
Reckoning with Race and Performing the Good News
Authors: Bacote Vincent E.
Published: November 2020

The “good news” is central to evangelical theology and the movement known as evangelicalism, but the news has not always been good for minorities who inhabit evangelical communities and institutions in the United States. Vincent Bacote argues a reckoning with questions of race is necessary for evangelical theology to help cultivate an evangelical movement more hospitable to minorities, particularly African-Americans. Evangelicalism is here regarded not only as a set of beliefs about the Bible, Christ’s work on the cross, conversion and witness but also as a set of dispositions and postures that create openness to the concerns of minorities. With a perpetually uneasy conscience, Christians within the evangelical movement can cultivate a disposition ready to learn from the questions and contributions of minorities in evangelical spaces, such as William Bentley and Carl Ellis. A better evangelical theology is proposed as doctrines that yield actions that are truly good news for all.
A critical analysis of the type of Navicula skuae with the description of a new Navicula species (Naviculaceae, Bacillariophyta) from the Antarctic Region

Authors: KOCHMAN-KĘDZIORA NATALIA , OLECH MARIA , VIJVER BART VAN DE
Published: November 2020

During a study of the limno-terrestrial diatoms on King George Island (South Shetland Islands), an unknown Navicula taxon was observed. Detailed morphological analysis based on both light and scanning electron microscopy observations revealed a unique set of morphological features, that were not observed in any Navicula taxon known so far. Despite an extensive literature search, it was not possible to identify this taxon and therefore it is described as a new species: Navicula massalskiana sp. nov. At present, the new species has only been observed from its type locality, acid soils influenced by penguin excrements, close to the seashore in the Admiralty Bay Region (King George Island). Navicula massalskiana shows a high similarity with two other Antarctic species: Navicula skuae and Navicula shackletonii. The taxonomic situation of these two taxa is investigated. The type material of Navicula skuae was reinvestigated and compared with the published morphological description of N. shackletonii. Based on this comparison, both taxa are clearly conspecific making N. skuae a later synonym of Navicula shackletonii.

Norovirus infection is the main cause of epidemic acute gastroenteritis outbreaks. As a result, norovirus merits careful attention. Acute gastroenteritis caused by norovirus is very harmful, necessitating effective prevention and monitoring. This study extracted norovirus using the
Fe3O4 nanomagnetic bead method while establishing a rapid and sensitive quantitative norovirus detection method for emergency use. Norovirus RNA was extracted from norovirus-positive stool samples, norovirus-specific primers were designed, and SYBR Green I fluorescent
dye was used to construct specific fluorescence quantitative reverse-transcription polymerase chain reaction (RT-PCR) method. Norovirus in the sample was successfully detected with the quantitative RT-PCR method established in this study, with a measured cycle threshold value of 28.73; the
melting temperature value of the PCR product was approximately 83.5 °C. Additionally, by analyzing melting curve with quantitative PCR and evaluating the repeatability of the detection method, the performance of the reaction system in terms of specificity and repeatability was determined
to be good. The fluorescence quantitative detection method established here can rapidly and effectively detect norovirus, and the method has good specificity and high repeatability. Currently, there is a trend of norovirus infection becoming increasingly severe. Thus, this rapid and sensitive
fluorescence quantitative detection method will play a significant role in the monitoring and detection of norovirus and is thus worthy of promotion and application.

Published: November 2020

Biomimetic peptide has attracted extensive attention in bone tissue repairing owing to its excellent biocompatibility and stability. Hydroxyapatite ceramics (HAP) possess both excellent mechanical properties and good biocompatibility. To study the effects of bionic peptide D9KIPKAS(pSer)VPTELSAISRGDS
on the interfacial activity and biological properties of hydroxyapatite ceramics, porous HAP ceramics were prepared using ammonium carbonate as a pore-forming agent. To explore the influence of surface modification on the interfacial activity of porous HAP ceramics when applying different
methods, surface modification was carried out using physical adsorption (HAP-p-PP2) and a chemically grafted polypeptide (HAP-c-PP2). X-ray diffraction was used to characterize the crystal morphology of the porous HAP ceramics before and after sintering. The results of FTIR and XPS showed
that bionic peptides were successfully grafted onto the surface of a porous HAP ceramic. An SEM graph shows the adhesion and spread of BMSCs on the materials. Meanwhile, the results of in vitro cell experiments showed that HAP-c-PP2 can better promote BMSC proliferation. In conclusion,
bionic peptide D9KIPKAS(pSer)VPTELSAISRGDS with multifunctional functional groups is more conducive to the adhesion, proliferation and differentiation of BMSCs which can make it play an effective role in osteoinduction in bone tissue engineering.
Effect of silica fume-enhanced carbon nanotube dispersion on the strength and damping properties of cement composites
Authors: Wang Miao , Lai Pengfei , Li Yongzhe , Yu Ping , Wang Zheng , Zhang Huilin
Published: November 2020

Carbon nanotubes (CNTs) tend to agglomerate in cement paste, which impedes the effect of performance reinforcement. This paper applies silica fume as an active factor to enhance the dispersion of CNTs and investigates the influence of silica fume on the strength and damping properties
of CNT-reinforced cement composites. Mechanical strength tests and dynamic mechanical analysis on specimens with different contents of CNTs (0%, 0.1% and 0.2%) and silica fume (0%, 5%, 10% and 15%) are conducted. The microstructure is characterized by Scanning Electron Microscopy (SEM), and
the pore size distribution is measured by Mercury Intrusion Porosimetry (MIP). Due to the CNT dispersion enhancement, both the number of gel pores and the size of microcapillary pores are reduced. The incorporation of silica fume also facilitates the interfacial friction between CNTs and cement
hydration products and promotes heat generation, when reciprocating loads are applied. The result indicates that the mixture proportion of CNTs and silica fume strongly influences the extent of the dispersion enhancement, which is optimized at 0.1% and 5%, respectively. Excessive addition
of either CNTs or silica fume will hinder CNT dispersion and subsequently reduce the strength and damping properties of the material, which should be avoided in practical applications.
Effect of inclusion on performance of A6N01 aluminum alloy joints
Authors: Ding Mengyu , Yu Min , Hua JunWei , Chen Hui
Published: November 2020

In order to study the effect of inclusion on performance of A6N01 aluminum alloy joints, the N-A6N01 and C-A6N01 aluminum alloys with different inclusion in amount and size were compared. Results show that the larger inclusions in amount and size in the N-A6N01 joint cause more pronounced
degradation in the tensile strength than the C-A6N01 joint. However, the N-A6N01 joint shows a superior fatigue strength to the C-A6N01 under the tensile fatigue, this probably because the degradation in the tensile strength contributes a uniform performance mating between the base metal and
WM, which reduces the stress concentration during the tensile loading process, and thus improving the fatigue strength.

To study and analyze the suitability of protein binding polyethylene glycol-polylactic acid nanoparticles (PEGPLA-NPs) for the treatment of cerebral thrombosis, and its influence on platelet parameters. Patients with cerebral thrombosis admitted to our hospital from April 2017 to May
2018 were randomly divided into the control and observation groups. Data on the clinical history and blood parameters of the patients were compared. After treatment with the protein binding PEG-PLA-NPs, the plasma viscosity and whole blood viscosity of the observation group were significantly
higher (p < 0.002) than those of the control group. The effective rate (93.3%) in the observation group was significantly higher than that of the control group (71.1%). The nanoparticles were characterized by high drug loading, high encapsulation efficiency, suitable preparation
and purification methods, optimal particle size and shape, and controlled drug release. Protein binding PEG-PLA-NPs, therefore, could be suitable modalities for the treatment of cerebral thrombosis, and be effective in improving patient conditions and subsequent rehabilitation.

ZnO has been widely used as piezoelectric materials in bulk acoustic resonators, especially in shear-mode film bulk acoustic resonators (FBAR). In this paper, we studied the effect of c-axis tilted ZnO thin film on shear mode FBAR in liquid environment. Mechanical impedances
of FBARs are compared between shear-mode and longitudinal-mode wave due to their different orientations of ZnO thin film. It is found ZnO thin film with 43° c-axis tilted angels induces quasi-shear-mode acoustic wave only. The Q values of FBAR with 43° c-axis tilted
ZnO are 256.94 in air at 0.8148 GHz, and 34.34 in water at 0.814 GHz, respectively. The shifts of the resonant frequencies are proportional to the square root of the product of viscosity and density of liquid medium, which is consistent with Kanazawa-Gordon theory and verified by actual experiment.

We have explored the structural evolution and electronic properties of cationic sodium chloride (NaCl)+n (n = 1–8) clusters. The global minimum of cationic (NaCl)+n clusters have been extensively searched using CALYPSO method
combined with DFT calculations. The structural evolution of (NaCl)+n clusters can be divided into three stages: linear structure, planar ring-like structure and three-dimensional structure. It is worth to note that cuboid structure is more common in the cluster series
as the cluster size increases. (NaCl)+4 clusters is identified as "magic number" clusters by means of the relative stabilities analyses. The following chemical bonding analysis indicate that the stability of (NaCl)+ 4cluster mainly comes from the interaction between Na
3s and Cl 3p atomic orbitals.

Using CuPc as the hole buffer material, the effect of 2T-NATA and CuPc as hole buffer materials in similar structure on the performance of devices is studied. For this reason, the ITO/CuPc (20 nm)/NPBX/DPVBi (20 nm) (15 nm)/Alq3: Rubrene (10, X nm)/Alq3 (40 nm)/LIF/Al (5 nm) light-emitting
device is designed. Referring to the previous papers on similar structure devices, the best effect is that the thickness of doped rubrene is 20 nm. In this paper, the thickness of Alq3 doping is 10 nm, the thickness of rubrene is adjusted to 5 nm, 10 nm, 15 nm, 20 nm and 25 nm, and the buffer
thickness of CuPc is selected at 20 nm according to the previous experimental results. The experimental results show that when the thickness of rubrene is 20 nm, the yellow light and blue light of the light-emitting materials tend to balance, and the device is close to the white light device.
The brightness and efficiency of the device are the highest, reaching and 21050 cd/m2 5.527 cd/A respectively. Compared with 2T-NATA as the buffer material, its luminous efficiency and brightness are improved. Through the analysis of the experimental results, we find that CuPc as
a hole buffer material reduces the hole carrier injection barrier, improves the hole injection ability, and enhances the recombination probability of hole and electron, improves the luminous efficiency and brightness of the device. It is concluded that 2T-NATA is more suitable than CuPc in
the aspect of practical application and energy saving. The advantage of CuPc is that it can inhibit the diffusion of chemical components in ITO to the hole transport layer, which is beneficial to the improvement on device performance and life.
Super-resolution ophthalmoscopy: Virtually structured detection for resolution improvement in retinal imaging

Published: November 2020

Quantitative retinal imaging is essential for advanced study and clinical management of eye diseases. However, spatial resolution of retinal imaging has been limited due to available numerical aperture and optical aberration of the ocular optics. Structured illumination microscopy has been established to break the diffraction-limit resolution in conventional light microscopy. However, practical implementation of structured illumination microscopy for in vivo ophthalmoscopy of the retina is challenging due to inevitable eye movements that can produce phase artifacts. Recently, we have demonstrated the feasibility of using virtually structured detection as one alternative to structured illumination microscopy for super-resolution imaging. By providing the flexibility of digital compensation of eye movements, the virtually structured detection provides a feasible, phase-artifact-free strategy to achieve super-resolution ophthalmoscopy. In this article, we summarize the technical rationale of virtually structured detection, and its implementations for super-resolution imaging of freshly isolated retinas, intact animals, and awake human subjects.
Developing the Juramento into an Evidence-Based Brief Intervention: A Brief Report
Authors: Garcia Victor , Lambert Emily , Heckert Alex , Pinchi Nahomy Hidalgo
Published: November 2020

Introduction:

This brief report recommends how the effectiveness of the juramento, a practice found in Mexican Catholicism, can be enhanced by combining it with Screening, Brief Intervention, and Referral to Treatment. The juramento is a grassroots intervention around a sacred pledge made to Our Lady of Guadalupe to abstain from alcohol from 6 months to 1 year.

Method:

The recommendations are made possible from an ongoing qualitative study on the use of the juramento among Mexican immigrant farmworkers in southeastern Pennsylvania. The subsample for this report is 15 Mexican immigrant farmworkers who made a juramento and two priests who administer the intervention.

Results:

Adding the Alcohol Use Disorders Identification Test and a referral to treatment in the counseling session of the juramento keeps its religious and cultural appeal. The core of the intervention—the ritualized pledge to Our Lady of Guadalupe—remains intact.

Conclusion:

Approaching the juramento with an evidence-based brief intervention lens will expand the availability of culturally based interventions to include a grassroots intervention in the Mexican immigrant community. The juramento is organic, rooted in culture and religion, making it more likely that it will help in reducing alcohol use disorders, especially those with strong religiosity.
Mahalanobis distance–based kernel supervised machine learning in spectral dimensionality reduction for hyperspectral imaging remote sensing
Authors: Liu Jing , Qiao Yulong
Published: November 2020

Spectral dimensionality reduction is a crucial step for hyperspectral image classification in practical applications. Dimensionality reduction has a strong influence on image classification performance with the problems of strong coupling features and high band correlation. To solve these issues, we propose the Mahalanobis distance–based kernel supervised machine learning framework for spectral dimensionality reduction. With Mahalanobis distance matrix–based dimensional reduction, the coupling relationship between features and the elimination of the scale effect are removed in low-dimensional feature space, which benefits the image classification. The experimental results show that compared with other methods, the proposed algorithm demonstrates the best accuracy and efficiency. The Mahalanobis distance–based multiples kernel learning achieves higher classification accuracy than the Euclidean distance kernel function. Accordingly, the proposed Mahalanobis distance–based kernel supervised machine learning method performs well with respect to the spectral dimensionality reduction in hyperspectral imaging remote sensing.

Published: November 2020

In this article, we report modeling, simulation, and analysis of shifting 2D photonic crystal cavity side holes in GaN-AlN-sapphire layered structure. The design was simulated with Lumerical finite-difference time-domain. A lattice constant a, 157 nm, and a hole diameter d, 106 nm, were used in the design. The cavities are based on L3, which we demonstrated by simply shifting two holes away from a line cavity with distances of 132, 142, and 152 nm, respectively. The highest quality factor, Q, value achieved is 2.25 × 104 at 152-nm cavity distance.
