Published: June 2020

Abstract
The flatness of large deployable antenna needs to be measured several times during the deployment test, the theodolite measurement accuracy was low and the speed was slow, and the laser radar measurement range was limited. By building a flatness rapid measurement system for large deployable antenna, using autonomous navigation mobile technology to plan measuring path, and using digital photogrammetry technology to detect the flatness of antenna. It can realize rapid and automatic measurement for flatness of large antenna. The test results show that the accuracy of digital photogrammetry camera and laser tracker is no more than 0.05mm; the measurement accuracy of the flatness rapid measurement system shall not be more than 0.034mm away from the accuracy of laser radar, it can meet the requirements of flatness rapid measurement of large deployable antenna. This method can improve the efficiency and automation level of flatness measurement of large deployable antenna, and it lays a foundation for the plane measurement of large deployable antenna with larger size and more complex structure.

Abstract
In accordance with the Radio Regulations, the S-band (Earth-to-Space 1980-2010 MHz, Space-to-Earth 2170-2200 MHz) is currently a shared frequency band both for the mobile service and the mobile-satellite (MSS) service. Both the terrestrial and satellite components of IMT have already been deployed or are being considered for deployment in some countries with the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz. Both the terrestrial and satellite components of IMT have already been deployed or are being considered for deployment. When Therefore, the potential interference issues between the two systems need to be studied. According to the characteristics of the terrestrial components of IMT and satellite mobile communication system, this paper analyzes the impact of the terrestrial components of IMT on satellite mobile communication system, and gives measures to eliminate interference.

Abstract
In order to investigate the effect of distortion energy on the microstructure of magnesium alloys prepared by strain induced melt activation (SIMA) process and partial remelting, Mg-6Al-0.9Gd magnesium alloys were deformed at 200 °C with 0-20% compression ratios, and the relationship between deformation and eutectic melting activation energy was established based on differential scanning calorimetry (DSC) analysis, thereby determining the distortion energy at different compression ratios. The results showed that distortion energy increased with increasing compression ratio, which contributed to the morphological transition from dentrictic to equiaxed structure, and accelerated the formation of liquid phase during subsequent partial remelting. All things (grain size, liquid fraction and distribution in the semi-solid microstructure) considered, the optimal compression ratio for this paper was 20%.

Published: June 2020

Abstract
In order to enhance the corrosion resistance and the quality of the phosphating film, nano-SiO2 was used in the phosphating solution.The structure and properties of the phosphating film were evaluated by SEM, electrochemistry, cupric sulfate drop corrosion test and film thickness measurement.The results show that the thickness of the phosphating film increases with the increase of nano-SiO2 content. The nano-SiO2 modified with vinyl triethoxy silane possessed good dispersibility in the phosphating solution, the phosphating solution with the addition of modified nano-SiO2 could greatly improve the corrosion resistance of the phosphating film.
Accurate Scallop Evaluation Method Considering Kinematics of Five-axis Milling Machine for Ball-end Mill
Authors: Hai Tuan Luu , Makhanov Stanislav S 
Published: June 2020

Abstract
A new algorithm to evaluate the scallops left between consecutive tool tracks after five-axis machining of a complex-shaped part surface has been proposed. The algorithm has been developed for the ball-nose cutter. The novelty of the algorithm includes a variable plane to evaluate the effective tool profile and the part surface profile, the orientation of the tool as well as non-linear kinematics of the five-axis machine. The proposed algorithm has been specifically designed for and tested on the industrial Stereo lithography (STL) format representing complex shaped synthetic five-axis parts and a model of a crown of the molar tooth. The procedure has been tested against several modifications of the conventional curvature based method and the sphere intersection method. The ground truth is generated using the solid modeling engine of Vericut 8.2. The algorithm provides a tangible accuracy increase in terms of the average and the maximum error with regard to the reference methods.

Published: June 2020

Abstract

Summary
The molecular changes induced by perturbations such as drugs and ligands are highly informative of the intracellular wiring. Our capacity to generate large datasets is increasing steadily. A useful way to extract mechanistic insight from the data is by integrating them with a prior knowledge network of signalling to obtain dynamic models. CellNOpt is a collection of Bioconductor R packages for building logic models from perturbation data and prior knowledge of signalling networks. We have recently developed new components and refined the existing ones to keep up with the computational demand of increasingly large datasets, including (i) an efficient integer linear programming, (ii) a probabilistic logic implementation for semi-quantitative datasets, (iii) the integration of a stochastic Boolean simulator, (iv) a tool to identify missing links, (v) systematic post-hoc analyses and (vi) an R-Shiny tool to run CellNOpt interactively.

Protecting the Public? An Analysis of Professional Regulation—Comparing Outcomes in Fitness to Practice Proceedings for Social Workers, Nurses and Doctors
Authors: Worsley Aidan , Shorrock Sarah , McLaughlin Kenneth 
Published: June 2020

AbstractThe regulation of professional activity in the Health and Social Care sector in the UK is carried out by a number of statutory bodies that hold legal mandates to manage the risks of professional malpractice. The prime method used to perform this duty, and thereby protect the public, is the construction of a register of the suitability qualified—and creation of appropriate professional standards to establish a benchmark for practice. When registrant’s performance or conduct is felt not to meet these standards, they are placed within a fitness to practice process administered by the regulatory body. This article examines the publicly available data on fitness to practice cases from UK regulatory bodies relating to the professions of social workers, nurses, midwives and doctors. Examining nearly 1,000 cases, the authors run a statistical analysis of the data to establish whether any differences are found amongst and between these professional groupings. We find there are several areas where significant differences arise, namely gender, attendance and representation. Most of these regulatory bodies are, in turn, regulated in the UK by the Professional Standards Authority (PSA), and the article concludes by suggesting ways forward for the PSA in addressing or further examining apparent inequalities. The analysis is placed within a wide range of literature, with an emphasis on the international transferability of the approach to professional regulation.
Genomic differentiation ofDeschampsia antarcticaandD. cespitosa(Poaceae) based on satellite DNA
Authors: González María Laura , Chiapella Jorge , Topalian Juliana , Urdampilleta Juan Domingo 
Published: June 2020

AbstractRepetitive DNA is a rapidly evolving component of vascular plant genomes, which can account for genomic differentiation in plant lineages. Satellite DNA (satDNA) is tandem repetitive DNA for which array size and disposition on chromosomes may vary between reproductively isolated groups, such as different populations or closely related species. Deschampsia is a cosmopolitan grass genus growing in temperate and cold regions; D. cespitosa is widespread all over the world, whereas D. antarctica is restricted to Antarctica and southern Patagonia. The present work aims to the identification, isolation and comparison of satDNA from the genomes of two Deschampsia spp. with bioinformatics tools and their subsequent analysis and cytological study. The genomic analysis of TAREAN found 34 families of satDNA included on 21 superfamilies, most of them shared between the two species. Some of these satDNAs presented homology with others previously reported for grasses. A few satDNA families were found exclusively in one of the species. Most satDNAs were found in both species and showed high sequence homology, but their distribution on chromosomes was different between species. This highlights the importance of changes in the genomic disposition of satDNA in the evolution of species. Based on the ‘satDNA library hypothesis’ the differential amplification of satDNAs between independent lineages may be the cause of such differences.

Published: June 2020

Abstract

Background
Neonatal herpes simplex virus infection (nHSV) leads to severe morbidity and mortality, but national incidence is uncertain. Florida regulations require that healthcare providers report cases, and clinical laboratories report test results when herpes simplex virus (HSV) is detected. We estimated nHSV incidence using laboratory-confirmed provider-reported cases and electronic laboratory reports (ELR) stored separately from provider-reported cases. Mortality was estimated using provider-reported cases, ELR, and vital statistics death records.

Methods
For 2011–2017, we reviewed: provider-reported cases (infants ≤ 60 days of age with HSV infection confirmed by culture or polymerase chain reaction [PCR]), ELR of HSV-positive culture or PCR results in the same age group, and death certificates containing International Classification of Disease, Tenth Revision, codes for herpes infection: P35.2, B00.0-B00.9, and A60.0-A60.9. Provider-reported cases were matched against ELR reports. Death certificates were matched with provider and ELR reports. Chapman’s capture-recapture method was used to estimate nHSV incidence and mortality. Mortality from all 3 sources was estimated using log-linear modeling.

Results
Providers reported 114 nHSV cases, and ELR identified 197 nHSV cases. Forty-six cases were common to both datasets, leaving 265 unique nHSV reports. Chapman’s estimate suggests 483 (95% confidence interval [CI], 383–634) nHSV cases occurred (31.5 infections per 100 000 live births). The nHSV deaths were reported by providers (n = 9), ELR (n = 18), and vital statistics (n = 31), totaling 34 unique reports. Log-linear modeling estimates 35.8 fatal cases occurred (95% CI, 34–40).

Conclusions
Chapman’s estimates using data collected over 7 years in Florida conclude nHSV infections occurred at a rate of 1 per 3000 live births.
Exposing the High Heterogeneity of Circulating Pro B-Type Natriuretic Peptide Fragments in Healthy Individuals and Heart Failure Patients
Authors: Amplatz Benno , Sarg Bettina , Faserl Klaus , Hammerer-Lercher Angelika , Mair Johannes , Lindner Herbert H 
Published: June 2020

Abstract

Background
The high molecular complexity of variably O-glycosylated and degraded pro B-type natriuretic peptide (proBNP) derived molecular forms challenges current immunoassays. Antibodies used show pronounced differences in cross-reactivities with these circulating fragments, which still need to be better characterized on a molecular level. To pave the way for advanced quantitative assays in the future, it is critical to fully understand these circulating forms.

Methods
Plasma samples were collected from 8 heart failure (HF) patients and 2 healthy controls. NT-proBNP and proBNP were purified by immunoprecipitation and analyzed by nano-flow liquid chromatography coupled to high-resolution mass spectrometry. Fragments formed during proteolysis in solution digestion were distinguished from naturally occurring peptides by using an 18O stable isotope labeling strategy.

Results
We detected 16 previously unknown circulating fragments of proBNP peptides (9 of which are located in the N-terminal and 7 in the C-terminal region), revealing a more advanced state of degradation than previously known. Two of these fragments are indicative of either unidentified processing modes or a far-reaching C-terminal degradation (or a combination thereof) of the precursor proBNP.

Conclusions
Our results further restrict ideal target epitopes for immunoassay antibodies and expand the current thinking of diversity, degradation, and processing of proBNP, as well as the distribution of circulating forms.
An Approach for the Evaluation and Correction of Manually Designed Video Game Levels Using Deep Neural Networks
Authors: Davoodi Omid , Ashtiani Mehrdad , Rajabi Morteza 
Published: June 2020

AbstractIn the current state of the video game productions, most of the video game levels are created by the human operators working as level designers. This manual process is not only time-consuming and resource-intensive but also hard to guarantee uniform quality in the contents created by the level designers. One way to address this issue is to use computer-assisted level design techniques. In this paper, we have proposed a novel framework for computer-assisted video game level design that leverages neural networks, particularly generative adversarial networks (GANs) and autoencoders. The general idea is to learn over a dataset of high-quality levels and subsequently improve the ones created by the level designers. The proposed method is independent of the graphical dimensionality of the game and will work for 2D and 3D games in general. The autoencoder is used to create an intermediate representation of the level that is itself changed using the backpropagation technique according to the feedback obtained by feeding the output of the autoencoder to the discriminator component of the GAN. After performing a series of evaluations on the proposed framework and by automatically improving a series of purposefully corrupted game levels, the results demonstrate a noticeable improvement compared with the usage of simple autoencoders used to improve the video game levels in the previous researches.

Published: June 2020

AbstractOBJECTIVESThe goal of this study was to report the long-term outcomes of patients with Marfan syndrome who had aortic surgery on any aortic segment except for the replacement of the aortic root itself.METHODSAn observational retrospective single-centre study was conducted with 115 Marfan syndrome patients who underwent 189 major aortic interventions from 1995 until 2018. Patients without aortic root replacement were identified and aortic root growth was analysed over time.RESULTSEleven of 115 patients (9.5%) did not have aortic root replacement during a follow-up of 10.5 [standard deviation (SD) 5.7] years and a mean age at last follow-up of 53.9 (SD 13.4) years. Patients without root replacement did not suffer less frequently from any type of acute aortic dissection (type A 27% vs 25%, P = 0.999; type B 36% vs 25%, P = 0.474). Patients with native aortic roots did not undergo fewer aortic interventions than those with aortic root replacement [12/11, mean 1.09 (SD 0.54) operations/patient vs 177/104, mean 1.7 (SD 1.3); P = 0.128]. Progression of the aortic root dimension was 0.5 (SD 0.3) mm/year in the group of patients with native aortic roots.CONCLUSIONSCurrent data suggest that 10% of patients with Marfan syndrome with previous aortic surgery will be free from aortic root replacement until the sixth decade of life.
Insufficient Advance Care Planning? Correlates of Planning Without Personal Conversations
Authors: Boerner Kathrin , Moorman Sara M , Carr Deborah , Ornstein Katherine A 
Published: June 2020

Abstract

Objectives
Advance care planning (ACP) typically comprises formal preparations (i.e., living will and/or durable power of attorney for health care) and informal discussions with family members and health care providers. However, some people complete formal documents without discussing them with others. If they become incapacitated, their appointed decision makers may lack guidance on how to interpret or enact their formal wishes. We document the prevalence and correlates of this partial approach to ACP.

Method
Using multinomial logistic regression models and data from a U.S. sample of 4,836 older adults in the 2018 wave of the National Health and Aging Trends Study (NHATS), this brief report evaluated associations between social integration indicators and the odds of completing (a) both discussions and formal plans (two-pronged ACP), (b) discussions only, (c) no ACP, and (d) formal ACP only (reference category). We adjust for demographic and health characteristics established as correlates of ACP.

Results
A minority (15%) of NHATS participants reported formal plans without having discussed them. Indicators of social isolation (e.g., smaller social networks and fewer social activities) increased the odds of engaging in formal planning only compared to two-pronged ACP. Socioeconomic disadvantage and probable dementia reduced the odds of having end-of-life conversations, whether as one’s only preparation or in tandem with formal preparations.

Discussion
Socially isolated persons are especially likely to do formal planning only, which is considered less effective than two-pronged ACP. Health care professionals should recognize that older adults with few kin may require additional support and guidance when doing ACP.
Bycatches of the red king crab in the bottom fish fishery in the Russian waters of the Barents Sea: assessment and regulations
Authors: Stesko Aleksei V , Bakanev Sergey V 
Published: June 2020

Abstract
An analysis of red king crab bycatch in bottom-trawl fisheries in the Russian exclusive economic zone (EEZ) in the Barents Sea based on data collected from 2010 to 2019 shows an annual range of 2.2–9.8 thousand tonnes of crab bycatch from 2010 to 2018, which is 0.7–2.9% of the total biomass of red king crab in the EEZ. It was found that the catch of commercially valuable male crabs in the bottom-trawl fishery ranged from 1.4 to 6.5 thousand tonnes, which is ∼0.7–3.3% of the total commercial stock. A protected area created in 2006 is estimated to prevent the catch of 1.1–4.8 thousand tonnes of crab; however, protective measures do not take into account the peculiarities of the current distribution of crab populations and the geography of the fishing area. This work offers suggestions for improving the regulatory measures to protect the king crab stock in Russian waters of the Barents Sea.
Higher Order Polars of Quasi-Ordinary Singularities
Authors: García Barroso Evelia R , Gwoździewicz Janusz 
Published: June 2020

Abstract
A quasi-ordinary polynomial is a monic polynomial with coefficients in the power series ring such that its discriminant equals a monomial up to unit. In this paper, we study higher derivatives of quasi-ordinary polynomials, also called higher order polars. We find factorizations of these polars. Our research in this paper goes in two directions. We generalize the results of Casas–Alvero and our previous results on higher order polars in the plane to irreducible quasi-ordinary polynomials. We also generalize the factorization of the first polar of a quasi-ordinary polynomial (not necessarily irreducible) given by the first-named author and González-Pérez to higher order polars. This is a new result even in the plane case. Our results remain true when we replace quasi-ordinary polynomials by quasi-ordinary power series.
A Theorem About Maximal Cohen–Macaulay Modules
Authors: Polstra Thomas 
Published: June 2020

Abstract
It is shown that for any local strongly $F$-regular ring there exists natural number $e_0$ so that if $M$ is any finitely generated maximal Cohen–Macaulay module, then the pushforward of $M$ under the $e_0$th iterate of the Frobenius endomorphism contains a free summand. Consequently, the torsion subgroup of the divisor class group of a local strongly $F$-regular ring is finite.
On the role of reduced wind mass-loss rate in enabling exoplanets to shape planetary nebulae
Authors: Hegazi Ahlam , Bear Ealeal , Soker Noam 
Published: June 2020

ABSTRACT
We use the stellar evolution code MESA–binary and follow the evolution of three exoplanets and two brown dwarfs (BDs) to determine their potential role in the future evolution of their parent star on the red giant branch (RGB) and on the asymptotic giant branch (AGB). We limit this study to exoplanets and BDs with orbits that have semimajor axis of $1 {~\rm au}\lesssim a_0 \lesssim 20 {~\rm au}$, a high eccentricity, $e_0 \gtrsim 0.25$, and having a parent star of mass M*,0 ≥ 1 M⊙. We find that the star HIP 75 458 will engulf its planet HIP 75 458b during its RGB phase. The planet will remove the envelope and terminate the RGB evolution, leaving a bare helium core of mass 0.4 M⊙ that will evolve to form a helium white dwarf. Only in one system out of five, the planet beta Pic c will enter the envelope of its parent star during the AGB phase. For that to occur, we have to reduce the wind mass-loss rate by a factor of about four from its commonly used value. This strengthens an early conclusion, which was based on exoplanets with circular orbits, which states that to have a non-negligible fraction of AGB stars that engulf planets we should consider lower wind mass-loss rates of isolated AGB stars (before they are spun-up by a companion). Such an engulfed planet might lead to the shaping of the AGB mass-loss geometry to form an elliptical planetary nebula.
