Effect of ECAP Deformation on Microstructure and Properties of Pure Magnesium
Authors: Qin Tipeng , Ban Chunyan , Hou Xiaoze 
Published: November 2020

Abstract
In this paper, the effect of the deformation of equal-channel angular pressing (ECAP) on the microstructure and the mechanical properties at room temperature was studied under the extrusion temperature of 350°C and extrusion path of BC. The results show that the grain size of pure magnesium is obviously refined with the increase of the number of extrusion passes. The yield strength, tensile strength and elongation of the as-cast sample are 20MPa, 55MPa and 14.7% respectively. The yield strength and tensile strength of the 3-pass extrusion sample can be increased by 350% and 170%, respectively. The tensile strength and yield strength of the 4-pass extrusion sample are reduced compared with the 3-pass extrusion sample, but the elongation is further increased. The grain refinement of alloy ECAP process is mainly a combination of mechanical shear and dynamic recrystallization.

Published: November 2020

Abstract
The pure MoS2-carbon composites (MoS2-C) and Fe modified MoS2-carbon composites (Fe/MoS2-C) were successfully synthesized through a facile two-step hydrothermal method by adding soft template of CTAB and applied as piezocatalysts to degrade Rhodamine B. The as-obtained catalysts were characterized by the X-ray diffraction (XRD) and scanning electron microscope (SEM). The results indicated the hybrids have large surface area, mesoporous structure, more edges and unsaturated S atoms. By comparing the muffle furnace samples (open air calcination) with the tube furnace one (closed Ar calcination), Fe/MoS2-C catalysts with tube furnace show the higher degradation activities (12.8% versus 5.8%). The possible degradation mechanisms are also discussed.

Authors: Guan Mengqin , Yao Liangke , Lin Tianxing , Jiang Zhuojun 
Published: November 2020

Abstract
This article discusses the effect on the mildew of polycarboxylic superplasticizer under different environmental temperature, sealing conditions, reaction temperature, acid-ether ratio, initiation system and compounding with different dosage of sodium gluconate. The results of the study indicate that the polycarboxylic superplasticizer should be kept as tightly as possible when not in use. In the case of the same cost performance, it can be selected to appropriately increase the acid-ether ratio, the reaction temperature, and reasonably select the additives with bactericidal effect for production.
Demonstration of Suppressed Backscattering in Acoustic Valley Hall Topological Insulator
Authors: Han Xiangzhen , Li Li , Hu Yujin , Wang Xuelin 
Published: November 2020

Abstract
Acoustic topological insulators are at the frontier of acoustic metamatetials research. The analogue of the quantum valley-Hall effect (QVHE) in sound waves has led to acoustic valley Hall topological insulators (VHTIs). Here, we construct a new acoustic VHTI with C3v- symmetric hexagonal cells. The sound propagation along the interface is demonstrated via simulations. By introducing defects along the interface, such as cavity or bendings, we observe the robust transports to these defects in acoustic VHTIs. In addition, we construct several waveguides to quantitatively analyze the suppressed backscattering. The results illustrate that the new designed acoustic VHTIs in this paper possess better backscattering suppression in sound propagation, although the penetration is lower than the previously designed acoustic VTHIs.

Authors: Li Zheng 
Published: November 2020

Abstract
Because of the inherent defects of fossil resources, replacing fossil resources with biomass resources is a great challenge in the 21st century. 2,5-Diformyl furan (DFF) and its derivatives are important value-added chemicals derived from biomass platform chemicals 5-hydroxymethylfurfural (HMF) and fructose, which have great application in the field of medicine, biopolymer and scientific research. It is of great significance to select suitable catalyst to complete the conversion. Polyoxometalate is anionic metal oxide clusters, due to their excellent thermal stability and redox ability, polyoxometalate are widely used in catalytic oxidation and have been gradually used in biomass value-added conversion. The preparation of DFF and its derivatives from HMF and fructose using polyoxometalate has become a research hotspot in recent years.
Research on the Effect of Different Esters on the Synthesis of Polycarboxylate Superplasticizer at Low Content
Authors: Yang Xiao Hong 
Published: November 2020

Abstract
This article uses three ester monomers, hydroxyethyl methacrylate (HEMA), hydroxyethyl acrylate (HEA), and hydroxypropyl acrylate (HPA), mixed with 2% of the mass of the macromonomer to synthesize Polycarboxylate Superplasticizer (PCE), compared with the blank sample without esters. The GPC technology was used to investigate the influence of different ester monomers on the molecular weight and distribution of PCE and the polymer yield at low dosages. The cement paste and concrete tests were carried out for testing the performance of PCE. Experiments proves that HEMA affects initial dispersion performance at low dosage. The article concludes that HEA and HPA indeed played a slow-release effect at low content.

Abstract
In the present work, the combination of the electrophoretic deposition of ZnO nanostructures with size not exceeding 50 nm, and the reduced graphene oxide (rGO) on gold electrodes was performed to study the non-enzymatic electrochemical detection of glucose. The effect of insulin insertion on glucose detection and regulation was studied and the electrochemical responses were compared with and without this molecule. The results showed that the GO/insulin/ZnO electrode is much more sensitive for the glucose detection, in addition to its ability to drop the insulin protein hormone under a negative voltage. That bears interest as dual function sensor for detection and regulation of glucose.

Published: November 2020

Abstract
Titanium alloys and nickel-based alloys have their own unique properties, and the bimetallic structure composed of the two alloys can be widely used in the aerospace field. However, the bimetallic structure which is fabricated by directly joining titanium alloys and nickel-based alloys via traditional methods is more sensitive to cracks due to the formation of intermetallic compounds. In this work based on laser additive manufacturing (LAM) technology, the TC4/IN718 bimetallic structure without metallurgical defects (such as cracks) was successfully fabricated via a Ta/Cu multi-interlayer. The test results indicated that the Ta/Cu multi-interlayer could effectively avoid the generation of Ti–Ni and Ti–Cu intermetallic compounds between TC4 and IN718. A good metallurgical combination was formed in each interface from TC4 to IN718 without metallurgical defects. The phase evolution from the TC4 region to the IN718 region was as follows: α-Ti → α-Ti + β-Ta → β-Ta → β-Ta + γ-Cu → γ-Cu → γ-Cu +γ-Ni + laves → γ-Ni + laves. The ultimate tensile strength of the bimetallic structure at room temperature was 369.32 MPa.

Published: November 2020

Abstract
The electronic structure and optical properties of intrinsic and doped Ca2Ge have been calculated by using the first-principles calculation method based on density functional theory. The doping content of As were 2.08% and 1.04%, respectively, and the doping concentrations of Ga were same with As. The band gap of intrinsic Ca2Ge is 0.556 eV, and that decreased to 0.526 eV and 0.548 eV with respect of As doping amount of 2.08% and 1.04%. Meanwhile, the band gap is 0.25 eV when the doping amount of Ga was 1.04%, and the band gap is 0.23 eV for Ga was 2.08%. The band structures results shown that the Fermi levels of As-doped (2.08% and 1.04%) are moved into the bottom of conduction band. The electronic density of sates shown that the electronic configurations at the top valence band and bottom conduction band were changed as As and Ga doped. The dielectric function results shown that the maximum value of 52.7 and 97.53 were respectively obtained at 0 eV for the 2.08% Ga-doped and the 1.04% As-doped. Moreover, the phenomenon of strong metallic reflection has been found in the energy range of 6.0 ∼ 8.5 eV, and the metal reflection characteristics of intrinsic Ca2Ge was greater than the doped Ca2Ge. Analyzing the energy-loss function, it indicating that the energy region of appearing energy loss can be altered by doping As and Ga or changing their doped concentration.
Tackling solid tumour therapy with small-format drug conjugates
Authors: Deonarain Mahendra P , Xue Quinn 
Published: November 2020

ABSTRACT
The pharmacokinetic–pharmacodynamic relationship is extremely complex and tumour drug penetration is one key parameter influencing therapeutic efficacy. In the context of antibody–drug conjugates (ADCs), which has undergone many innovation cycles and witnessed many failures, this feature is being addressed by a number of alternative technologies. Immunoglobulin-based ADCs continue to dominate the industrial landscape, but smaller formats offer the promise of more-effective cytotoxic payload delivery to solid tumours, with a higher therapeutic window afforded by the more rapid clearance. To make these smaller formats viable as delivery vehicles, a number of strategies are being employed, which will be reviewed here. These include identifying the most-appropriate size to generate the larger therapeutic window, increasing the amount of functional, cytotoxic payload delivered through conjugation or half-life extending technologies or other ways of extending the dosing without inducing toxicity.
What is “global Islam”?
Authors: Green Nile 
Published: November 2020

Abstract
“What is global Islam?” is a question of definition that, like global Islam itself, can be answered by first looking at what it is not. How does global Islam differ from world Islam? Global Islam is driven by methods used by transnational actors to spread messages worldwide, while world Islam flourishes away from communication networks. Before the “first globalization” with the rise of steam travel and the printing press, religious power and knowledge were largely concentrated in a group of Sunni leaders. Technology enabled new voices to challenge the established order. This challenge continues today via satellite channels, international societies and organizations, and online communities.
1865 and after the war
Authors: Masur Louis P. 
Published: November 2020

Abstract
“1865 and after the war” begins with the Confederacy taking desperate measures to try and reverse its fortunes. In March, Lincoln delivered his second inaugural and in April, Robert E. Lee and Ulysses S. Grant met at Appomattox to agree to the terms of surrender. Less than a week later, Lincoln was assassinated. In the aftermath, President Johnson battled with Congress over the terms of reconstruction. New amendments and educational initiatives helped freedmen, but their fortunes were mixed as Southern Democrats and former slave owners regained political power. In the 1870s, financial panic seized America, shifting the focus away from the South and bringing a close to the era of war and reconstruction.
‘Their Voices Ring in My Ears’:Laura, the Fugue, and Adaptation
Authors: Toth Margaret A , Ramoni Teresa 
Published: November 2020

AbstractThis essay analyzes Vera Caspary’s novel Laura (1943) and the 1944 film adaptation (Preminger) in order to demonstrate an approach to adaptation studies we call fugal. If a fugue is a composition based on a ‘subject’ or short melodic phrase and its various ‘answers’—in other words, variations that maintain elements of the melody but also play with and revise it—how might we position the film as a variation on, rather than a reproduction of, Caspary’s novel? To explore this question, we analyze the sonic register of both the novel and film. Caspary doesn’t want us to merely read her novel; she wants us to listen to the voices that narrate it and the tunes that populate it. Similarly, listening to the film—not simply the dialogue but also the voiceover narration and David Raksin’s groundbreaking score—allows us to identify content not overt in, and sometimes at odds with, the visuals. When we listen critically and carefully, we can distinguish nuances that get lost in a strict fidelity approach; in particular, we can identify both works’ feminist content, especially their attempts to decentre patriarchal hard-boiled conventions and to confound notions of a singular truth.
Single-locus species delimitation and ecological niche modelling provide insights into the evolution, historical distribution and taxonomy of the Pacific chorus frogs
Authors: Jadin Robert C , Orlofske Sarah A , Jezkova Tereza , Blair Christopher 
Published: November 2020

AbstractThe Pacific chorus frogs are a complex of three wide-ranging species (i.e. Hyliola hypochondriaca, Hyliola regilla, Hyliola sierra) whose current taxonomy remains unresolved. We conducted species delimitation analyses of these taxa using fragments of the cytochrome b and 12S–16S mtDNA genes to assess the species diversity. Importantly, we included samples from new locations throughout the range to better understand species distributions and identify potential contact zones among clades. Our analyses revealed three slightly parapatric but distinct species-level clades. Molecular dating revealed that these species began diverging in the Pleistocene c. 1.4 Mya with H. hypochondriaca and H. sierra diverging more recently c. 0.8 Mya. We found that populations from western Montana and Idaho originated recently from populations to the southwest that belong to H. sierra, rather than from H. regilla populations directly to the west. Population sizes of each species expanded c. 130–80 Kya with H. hypochondriaca exhibiting a more pronounced expansion beginning c. 100 Kya than the more gradual expansion of the other two species. The climatic niche models suggest that distributions of the three species were similar during the last interglacial (LIG) as they are today. During the Last Glacial Maximum (LGM), H. hypochondriaca and H. sierra occupied a larger range than they do today whereas H. regilla occupied a smaller refugium, shifted south from the current distribution. This study highlights the continued effectiveness of utilizing single-locus data sets for species delimitation and biogeographic analyses.

Published: November 2020

AbstractAutism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are common neurodevelopmental disorders (NDDs) that may impact brain maturation. A number of studies have examined cortical gyrification morphology in both NDDs. Here we review and when possible pool their results to better understand the shared and potentially disorder-specific gyrification features. We searched MEDLINE, PsycINFO, and EMBASE databases, and 24 and 10 studies met the criteria to be included in the systematic review and meta-analysis portions, respectively. Meta-analysis of local Gyrification Index (lGI) findings across ASD studies was conducted with SDM software adapted for surface-based morphometry studies. Meta-regressions were used to explore effects of age, sex, and sample size on gyrification differences. There were no significant differences in gyrification across groups. Qualitative synthesis of remaining ASD studies highlighted heterogeneity in findings. Large-scale ADHD studies reported no differences in gyrification between cases and controls suggesting that, similar to ASD, there is currently no evidence of differences in gyrification morphology compared with controls. Larger, longitudinal studies are needed to further clarify the effects of age, sex, and IQ on cortical gyrification in these NDDs.

Published: November 2020

Abstract
The consensus definitions of invasive fungal diseases from the EORTC/MSGERC were recently revised and updated. They now include consensus cutoff values for the galactomannan test that support the diagnosis of probable invasive aspergillosis. In this supplement article, we provide a rationale for these proposed thresholds based on the test’s characteristics and performance in different patient populations and in different specimen types.

Published: November 2020

Abstract

Background
A novel, recently FDA-authorized software uses deep learning (DL) to provide prescriptive transthoracic echocardiography (TTE) guidance, allowing novices to acquire standard TTE views. The DL model was trained by &gt;5,000,000 observations of the impact of probe motion on image orientation/quality. This study evaluated whether novice-acquired TTE images guided by this software were of diagnostic quality in patients with and without implanted electrophysiological (EP) devices, focusing on RV size and function, which were thought to be sensitive to EP devices. Some aspects of the study have previously been presented.

Methods
240 patients (61±16 years old, 58% male, 33% BMI &gt;30 kg/m2, 91% with cardiac pathology) were recruited. 8 nurses without echo experience each acquired 10 view TTEs in 30 patients guided by the software. 235 of the patients were also scanned by a trained sonographer without assistance from the software. 5 Level 3 echocardiographers independently assessed the diagnostic quality of the TTEs acquired by the nurses and sonographers to evaluate the effect of EP devices on DL software performance.

Results
Nurses using the AI-guided acquisition software acquired TTEs of sufficient quality to make qualitative assessments of right ventricular (RV) size and function in greater than 80% of cases for patients with and without implanted EP devices (Table). There was no significant difference between nurse- and sonographer-acquired scans.

Conclusion
These results indicate that new DL software can guide novices to obtain TTEs that enable qualitative assessment of RV size even in the presence of implanted EP devices. The results of the comparison to sonographer-acquired exams indicate the software performance is robust to presence of pacemaker/ICD leads visible in the images (Figure).
