Textural characteristics, mode of transportation and depositional environment of the Cretaceous sandstone in the Bredasdorp Basin, off the south coast of South Africa: Evidence from grain size analysis
Authors: Baiyegunhi Temitope Love , Liu Kuiwu , Gwavava Oswald , Baiyegunhi Christopher 
Published: December 2020

Abstract
A total of 92 representative sandstone samples of the Bredasdorp Basin in boreholes E-AH1, E-AJ1, E-BA1, E-BB1 and E-D3 have been investigated for their grain size characteristics. Grain size textural parameters and their cross plots, linear discriminate functions (LDFs), C–M (C = first percentile and M = median) diagram and log–probability plots were calculated and interpreted to understand the mode of transportation and hydrodynamic conditions and also to unravel the depositional environments of the sediments. The grain size textural parameters revealed that the Bredasdorp sandstones are unimodal, predominantly fine-grained, moderately well-sorted, mesokurtic and near symmetrical. The bivariate plots of grain size textural parameters indicate that the depositional environments had been influenced mainly by river/beach/coastal dune conditions. The LDF plots show that the sediments are turbidity current deposits in a shallow marine environment. The C–M diagram revealed that the studied sandstones were mainly deposited by traction currents and beach process. In addition, the grain size log–probability curves and C–M diagram show the predominance of suspension and saltation modes of sediment transportation. Based on the inter-relationship of the various statistical parameters, it is deduced that the Bredasdorp Basin are mainly shallow marine deposits with signature of beach and coastal river processes.

Abstract

Objectives
Early-life stress (ELS) increases the risk of metabolic disorders in later life. The present study investigated the ELS effect on pancreatic pyruvate dehydrogenase (PDH) protein level, α-ketoglutarate dehydrogenase (α-KGDH), and aconitase activities as metabolic enzymes in response to young adulthood stress in male rat offspring.

Methods
Male Wistar rats were divided into six groups: Control, early life stress (Early STR), young adult foot-shock stress (Y. adult F-SH STR), early + young adult foot-shock stress (Early + Y. adult F-SH STR), young adult psychological stress (Y. adult Psy STR) and early + young adult psychological stress (Early + Y. adult Psy STR). Stress was induced by a communication box at 2 weeks of age and young adulthood for five consecutive days. The blood samples were collected in young adult rats, then pancreases were removed to measure its PDH protein level and aconitase and α-KGDH activities.

Results
In ELS animals, applying foot-shock stress in young adulthood increased PDH protein level, decreased α-KGDH and aconitase activities, and increased plasma glucose, insulin, and corticosterone concentrations. However, exposure to young adulthood psychological stress only decreased α-KGDH and aconitase activities.

Conclusions
It seems that ELS altered metabolic response to young adulthood stress through changes of Krebs cycle-related enzymes activities, though the type of adulthood stress was determinant.
El tratamiento de la mitología en las comedias religiosas de Calderón
Authors: Morata Isabel Hernando 
Published: December 2020

ResumenEl objetivo de este artículo es determinar el tratamiento de la mitología clásica en las comedias religiosas de Calderón, especialmente enLos dos amantes del cielo,El mágico prodigiosoyEl José de las mujeres. Se atiende sobre todo a los debates que se establecen en ellas sobre la existencia de los dioses paganos, en los que el defensor de estas divinidades suele ser el Demonio. El rechazo de la mitología clásica que se aprecia en las comedias religiosas de Calderón contrasta con su empleo en el teatro cortesano y en los autos sacramentales.
Solving a linear fractional equation with nonlocal boundary conditions based on multiscale orthonormal bases method in the reproducing kernel space
Authors: Jiang Wei , Chen Zhong , Hu Ning , Chen Yali 
Published: December 2020

Abstract
In recent years, the study of fractional differential equations has become a hot spot. It is more difficult to solve fractional differential equations with nonlocal boundary conditions. In this article, we propose a multiscale orthonormal bases collocation method for linear fractional-order nonlocal boundary value problems. In algorithm construction, the solution is expanded by the multiscale orthonormal bases of a reproducing kernel space. The nonlocal boundary conditions are transformed into operator equations, which are involved in finding the collocation coefficients as constrain conditions. In theory, the convergent order and stability analysis of the proposed method are presented rigorously. Finally, numerical examples show the stability, accuracy and effectiveness of the method.
Abundant rogue wave solutions for the (2 + 1)-dimensional generalized Korteweg–de Vries equation
Authors: Lu Huanhuan , Zhang Yufeng 
Published: December 2020

Abstract
In this paper, we analyse two types of rogue wave solutions generated from two improved ansatzs, to the (2 + 1)-dimensional generalized Korteweg–de Vries equation. With symbolic computation, the first-order rogue waves, second-order rogue waves, third-order rogue waves are generated directly from the first ansatz. Based on the Hirota bilinear formulation, another type of one-rogue waves and two-rogue waves can be obtained from the second ansatz. In addition, the dynamic behaviours of obtained rogue wave solutions are illustrated graphically.

Published: December 2020

Abstract
G protein-coupled receptors (GPCRs) play an essential role in critical human activities, and they are considered targets for a wide range of drugs. Accordingly, based on these crucial roles, GPCRs are mainly considered and focused on pharmaceutical research. Hence, there are a lot of investigations on GPCRs. Experimental laboratory research is very costly in terms of time and expenses, and accordingly, there is a marked tendency to use computational methods as an alternative method. In this study, a prediction model based on machine learning (ML) approaches was developed to predict GPCRs and ligand interactions. Decision tree (DT), random forest (RF), multilayer perceptron (MLP), support vector machine (SVM), and Naive Bayes (NB) were the algorithms that were investigated in this study. After several optimization steps, receiver operating characteristic (ROC) for DT, RF, MLP, SVM, and NB algorithm were 95.2, 98.1, 96.3, 95.5, and 97.3, respectively. Accordingly final model was made base on the RF algorithm. The current computational study compared with others focused on specific and important types of proteins (GPCR) interaction and employed/examined different types of sequence-based features to obtain more accurate results. Drug science researchers could widely use the developed prediction model in this study. The developed predictor was applied over 16,132 GPCR-ligand pairs and about 6778 potential interactions predicted.

Authors: Sabitu Rabiu Imam , Khan Nafizah Goriman , Malekmohammadi Amin 
Published: December 2020

Abstract
This report examines the performance of a high-speed MDM transmission system supporting four nondegenerate spatial modes at 10 Gb/s. The analysis adopts the NRZ modulation format to evaluate the system performance in terms of a minimum power required (PN) and the nonlinear threshold power (PTH) at a BER of 10−9. The receiver sensitivity, optical signal-to-noise ratio, and the maximum transmission distance were investigated using the direct detection by employing a multimode erbium-doped amplifier (MM-EDFA). It was found that by properly optimizing the MM-EDFA, the system performance can significantly be improved.

Published: December 2020

Abstract
In this study, six different types of optical fibers (SMF, HNLF, HNL-DFF, NZDSF, LEAF (step core) and LEAF (ring core)) can be used for different number of channels (16, 32, 64, and 80) at different bit rates to calculate the quality factor for these types of optical fibers at the optimum length for max BER × 10−9 and min BER × 10−12. By using the software Optisystem version 13, the work has been demonstrated and compared with previous study to find the best one under the same operating conditions.

Published: December 2020

Abstract
The work offered the analysis comparison study of optical wireless intersatellite link (ISL) for both different bit sequence generators and filters. The study clarifies the impact of varying sorts of both bit sequence generator (data source) in the transmitter and electrical filters in receiver on system performance. The two bit sequence generators used are pseudo random bit sequence generator (PRBSG) and user-defined bit sequence generator (UDBSG). The used filters in this study are low pass (LP) Bessel filter, LP Gaussian filter, LPCROF (cosine roll-off filter), and LPSCROF (squared CROF). Performance of the filter depends on the order of filter and filter bandwidth. The performance parameters in our study are quality factor, Bit Error Rate (BER), and optical received power. In this study, variation of optical received power depends on the type of sequence generator because it is measured after the channel directly.

Abstract

Objectives
Graves’ disease (GD) is rare in children under age five years. Antithyroid drugs are typically first-line therapy but carry the risks of agranulocytosis and liver dysfunction.

Case presentation
A male infant with multiple congenital anomalies, left ventricular hypertrophy, and neurologic dysfunction developed GD at five months of life. The presence of chronic hepatitis complicated medical management. Potassium iodide was effective temporarily, but urgent thyroidectomy was required at nine months of age. Postoperatively, the patient developed a thyroid function pattern consistent with impaired pituitary sensitivity to thyroid hormone (TH) that responded to the addition of liothyronine. Exome sequencing revealed a heterozygous de novo duplication of the ATAD3 gene cluster, suggesting a possible mitochondrial disorder.

Conclusions
This case describes the youngest child to date to be diagnosed with endogenous GD and to successfully undergo definitive treatment with thyroidectomy. An underlying defect in mitochondrial function is suspected, suggesting a potential novel pathophysiologic link to early-onset thyroid autoimmunity. Additionally, this case illustrated the development of impaired pituitary sensitivity to TH following thyrotoxicosis of postnatal onset, which may contribute to our understanding of hypothalamic-pituitary-thyroid (HPT) axis development.
False-positive very long-chain fatty acids in a case of autoimmune adrenal insufficiency
Authors: Zhu Jia , Breault David T. 
Published: December 2020

Abstract

Background
X-linked adrenoleukodystrophy (ALD) affects up to 25% of boys diagnosed with adrenal insufficiency in childhood. Because early identification of these individuals can be lifesaving, all boys with new-onset primary adrenal insufficiency should be tested for ALD with a plasma very long-chain fatty acid (VLCFA) level. While plasma VLCFA is a diagnostic test with high sensitivity and specificity, false-positive results have been reported in individuals on a ketogenic diet.

Case presentation
We present a case of an 11-year-old boy with new-onset primary adrenal insufficiency due to autoimmune adrenalitis who was initially found to have elevated VLCFA levels, suggestive of ALD, that normalized on repeat testing.

Conclusions
As advances in gene therapy and newborn screening for ALD expand, VLCFA testing may increase, and clinicians should be aware that testing during the initial presentation of primary adrenal insufficiency may lead to false-positive results and associated psychosocial distress.
Double moiré localized plasmon structured illumination microscopy
Authors: Röhrich Ruslan , Koenderink A. Femius 
Published: December 2020

Abstract
Structured illumination microscopy (SIM) is a well-established fluorescence imaging technique, which can increase spatial resolution by up to a factor of two. This article reports on a new way to extend the capabilities of structured illumination microscopy, by combining ideas from the fields of illumination engineering and nanophotonics. In this technique, plasmonic arrays of hexagonal symmetry are illuminated by two obliquely incident beams originating from a single laser. The resulting interference between the light grating and plasmonic grating creates a wide range of spatial frequencies above the microscope passband, while still preserving the spatial frequencies of regular SIM. To systematically investigate this technique and to contrast it with regular SIM and localized plasmon SIM, we implement a rigorous simulation procedure, which simulates the near-field illumination of the plasmonic grating and uses it in the subsequent forward imaging model. The inverse problem, of obtaining a super-resolution (SR) image from multiple low-resolution images, is solved using a numerical reconstruction algorithm while the obtained resolution is quantitatively assessed. The results point at the possibility of resolution enhancements beyond regular SIM, which rapidly vanishes with the height above the grating. In an initial experimental realization, the existence of the expected spatial frequencies is shown and the performance of compatible reconstruction approaches is compared. Finally, we discuss the obstacles of experimental implementations that would need to be overcome for artifact-free SR imaging.

Published: December 2020

Abstract
In this work, a strain-based degradation model was implemented and validated to better understand the dynamic interactions between the bioresorbable vascular scaffold (BVS) and the artery during the degradation process. Integrating the strain-modulated degradation equation into commercial finite element codes allows a better control and visualization of local mechanical parameters. Both strut thinning and discontinuity of the stent struts within an artery were captured and visualized. The predicted results in terms of mass loss and fracture locations were validated by the documented experimental observations. In addition, results suggested that the heterogeneous degradation of the stent depends on its strain distribution following deployment. Degradation is faster at the locations with higher strains and resulted in the strut thinning and discontinuity, which contributes to the continuous mass loss, and the reduced contact force between the BVS and artery. A nonlinear relationship between the maximum principal strain of the stent and the fracture time was obtained, which could be transformed to predict the degradation process of the BVS in different mechanical environments. The developed computational model provided more insights into the degradation process, which could complement the discrete experimental data for improving the design and clinical management of the BVS.
The role of abiotic and biotic factors in interspecific competition of Polish crayfish – comprehensive literature review
Authors: Wiśniewski Kamil , Szarmach Daniel , Poznańska-Kakareko Małgorzata 
Published: December 2020

Abstract
Invasive species are those that have been transferred by humans out of their natural range. Native crayfish species in Polish waters include: Astacus astacus and Pontastacus leptodactylus, whereas invasive species are: Pacifastacus leniusculus, Faxonius limosus, Procambarus clarkii and Procambarus virginalis. The objective of this study was to determine how abiotic and biotic environmental factors contribute to interspecific competition of Polish crayfish based on the available literature. Abiotic factors affecting the interspecific competition include tolerance to extreme pH values, calcium ion content, temperature, oxygenation, water salinity, preferred substrate and the type of water bodies. Biotic factors are, inter alia, pathogens, food base, plant cover and interactions in the prey–predator system, as well as interactions between crayfish species. The most important abiotic factors are water temperature and oxygenation, while the most important biotic factor is the crayfish plague – a deadly disease for native species. Each invasive species has a different set of traits and adaptations that enable a successful invasion. However, a successful invasion of a given species is not determined by one, but many adaptations that coexist.

Authors: Mohidem Nur Adibah , Hashim Zailina , Osman Malina , Muharam Farrah Melissa , Elias Saliza Mohd , Shaharudin Rafiza 
Published: December 2020

Abstract

Objective
To investigate the prevalence and incidence of TB by focusing on its environmental risk factor in Malaysia.

Content
Databases search of Scopus, ScienceDirect, PubMed, Directory of Open Access Journals (DOAJ), Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus, MyJournal, Biblioteca Regional de Medicina (BIREME), BioMed Central (BMC) Public Health, Medline, Commonwealth Agricultural Bureaux (CAB), EMBASE (Excerpta Medica dataBASE) OVID, and Web of Science (WoS) was performed, which include the article from 1st January 2008 until 31st August 2018 using medical subject heading (MeSH). Articles initially identified were screened for relevance.

Summary
Out of 744 papers screened, nine eligible studies did meet our inclusion criteria. Prison and housing environments were evaluated for TB transmission in living environment, while the other factor was urbanization. However, not all association for these factors were statistically significant, thus assumed to be conflicting or weak to end up with a strong conclusion.

Outlook
Unsustainable indoor environment in high congregate setting and overcrowding remained as a challenge for TB infection in Malaysia. Risk factors for transmission of TB, specifically in high risk areas, should focus on the implementation of specialized program. Further research on health care environment, weather variability, and air pollution are urgently needed to improve the management of TB transmission.
