Theoretical insights into the effects of RE doping on the structural, electronic, and optical properties of magnesium clusters
Authors: Lu Xianghang , Gao Feng , Chen Yingying , Jiang Gang 
Published: March 2022

Doping of magnesium-based materials with the rare earth (RE) elements allows one to adjust or modify the structures and properties of the materials. In the present work, the structural, electronic, and optical properties of the global minima Mgn (n = 2–10) and MgnX (X = Sc, Y, La, Nd, Gd, n = 1–9) clusters have been examined using the density functional theory (DFT) and the time-dependent DFT. The identified structures show that the RE atoms tend to occupy the center of the surface of the geometries, which enhances their structural stability. Further analyses on average bonding energies, the second-order differences in energy, and HOMO–LUMO gaps indicate that the Mg3Nd cluster is more stable than others. The excellent stability of this cluster is caused by the strong Nd 4f and Mg 2p interactions through the analyses of molecular orbitals. The natural population analyses imply that the electron transfers mainly occur among the s-p-d orbitals in MgnX (X = Sc, Y, La) clusters and the s-d-f orbitals in MgnX (X = Nd, Gd). In addition, the results of the excited-state calculations reveal that the absorption spectra of all MgnX clusters emerge red-shift phenomena compared with that of Mgn, and the absorbance strongest resonances of Mg4X clusters concentrate at visible light region (about 600 nm).
Piracy and the commodification of originality in translation
Authors: Qi Lintao 
Published: March 2022

Abstract
Translation is often considered in relation to the original, as if the original were always singular, fixed, stable, and incontestable. Readers, translators, and publishers, however, may approach the concept of original(ity) from diverse perspectives, conditioned by specific sociocultural contexts. Using Chinese translations of the Australian novel The Thorn Birds as a case study, this article situates its examination of original(ity) in the context of Chinese publishing industries, in which copyright laws and piracy unusually co-exist. The resultant tension between authorized publishers and counterfeiters gives rise to a situation where originality is highly commodified and thus frequently reconstructed. Translation research on original(ity), therefore, must move beyond legal and ethical dimensions to include economic, political, and historical contexts. Original(ity), which may be considered a collective property of both the original(s) and the translation(s), has to be constantly reinterpreted in a given sociocultural context at each new historical moment.
Thermodynamics of the black holes under the extended generalized uncertainty principle with linear terms
Authors: Su He , Long Chao-Yun 
Published: March 2022

Abstract
In this paper, we employ the extended generalized uncertainty principle with linear terms (LEGUP) to investigate the thermodynamics properties of the Schwarzschild and Reissner–Nordström (RN) black holes. Firstly, by constructing the theoretical framework of LEGUP, the minimal temperature of the Schwarzschild black hole and the modified mass–temperature function for the black hole are calculated. Furthermore, the heat capacity function for the Schwarzschild black hole is obtained. After that, we compare LEGUP black hole thermodynamics with EGUP black hole and with the usual forms. Besides, the modification of black hole entropy is discussed, which involves a heuristic analysis of particles absorbed by the black hole. Finally, we derive the LEGUP-corrected temperature, heat capacity and entropy functions of the RN black hole.

Authors: Wicaksono I T , Nurwidayati R 
Published: March 2022

Abstract
This research examined the effect of acid water as a concrete mix material and as a curing system on the compressive strength of concrete. The effect of wet-dry curing conditions in normal and low pH water on the concrete compressive strength was also evaluated. The water pH of 3 and 7 was conducted in this research. Water pH of 3 was obtained by diluting the HCl solution with tap water. The result showed that the concrete compressive strengths with normal water were 26.23, 26.61, 28.31, and 28.31 MPa at 28, 56, 90, and 120 days, respectively. In comparison, concrete mixed with low pH water was 25.48, 26.04, 26.42, and 26.42 MPa at 28, 56, 90, and 120 days, respectively. The wet-dry curing system for normal water concrete mixed reduced the compressive strength at 28 days by 14.39%, 56 days by 18.44%, 90 days by 14.00%, and 120 days by 10.00%. The wet-dry curing with acidic water also decreased the concrete compressive strength. The wet-dry condition breaks the hydration process between concrete and acid water. Wet-dry curing decreased the compressive strength of concrete. The compressive strength at 28, 56, and 90days decreased 16.30, 12.32, and 7.86%, respectively. While at 120 days, the compressive strength on wet-dry curing slightly increased by 1.43% by 0.01%. Wet-dry curing breaks the concrete hydration process with acid water.

Published: March 2022

Abstract
This study is centered on automatic mapping approach to identify and count coconut trees in the municipality of San Fernando, Cebu for the purpose of source mapping for viable sustainable construction materials. Through the employment of theories and applications of Object-Based Image Analysis (OBIA), a rule set was developed in eCognition Developer to automatically identify and count coconut trees in orchards. The data used in the rule set were the red, green and blue (RGB) spectral bands of the orthophoto with a spatial resolution of 0.50m, and the Normalized Digital Surface Elevation (NDSM) with a spatial resolution of 1.0m. The mapping approach yielded an overall accuracy, user accuracy and producer accuracy of 71.19%, 78.82% and 88.02%, respectively. The run time of automatic detection of the coconut trees in the sampling area was recorded to be 30 seconds, taking a significantly shorter amount of time than visually analysing the area with a recorded time of 90 minutes. The application of the developed rule set to the entire municipality resulted in 96, 099 detected coconut trees with Barangay Cabatbatan having the highest tree count of 36, 621 in a land area of 19.336 square kilometres.
Stabilization of Soft Clay from Bukit Rawi using Portland Composite Cement
Authors: Arifin Y F , Rahmah R F 
Published: March 2022

Abstract
One method for stabilizing soft clay is to mix it with cement. Portland composite cement (PCC) is a cement produced by grinding together portland slag and gypsum with one or more inorganic materials that is suitable for stabilization of soft soils. The purpose of this study was to mix soft clay from Bukit Rawi, Central Kalimantan with PCC, which was then tested for unconfined compression strength (UCS) and the California Bearing Ratio (CBR) to see if it could be used as a road subgrade. Soft soil from Bukit Rawi was mixed with PCC with percentages of 6%, 8%, 10%, and 12% on a dry weight basis. The mixture was tested by Proctor standard compaction to obtain the optimum moisture content and maximum dry density. At these optimum conditions, UCS and CBR tests were carried out. The findings reveal that adding PCC to Bukit Rawi soil enhances UCS and CBR, which were previously 3.47% of CBR and 0.67kg/cm2 of UCS. The addition of PCC with a level of 2‒3% is planned for field application, because it is considered capable of fulfilling the requirements as a subgrade layer with a CBR of 15%. Furthermore, 12 percent PCC is required in the combination as a foundation (minimum 20kg/cm2 of UCS).
Green synthesis of cerium oxide nanoparticles from turmeric and kinds of honey: characterisations, antioxidant and photocatalytic dye degradation activities
Authors: Kalaycıoğlu Zeynep , Geçim Bersu , Erim F Bedia 
Published: March 2022

Abstract
The environmentally compatible and cost-effective green synthesis of cerium oxide nanoparticles (CeO2-NPs) was performed starting from bioactive natural materials, i.e., blossom, pine, chestnut honey, and turmeric extracts. The sizes, surface charges, morphologies, band gap energies, antioxidant, and photocatalytic activities of the synthesised nanoparticles were examined comparatively. The x-ray diffraction (XRD) studies confirmed the crystallinity and purity of CeO2-NPs. Transmission electron microscope (TEM) images indicated that the CeO2-NPs synthesised have spherical shapes. Particle sizes of honey originated NPs changed as 1.23, 2.61, 3.02 nm for the blossom, chestnut, and pine honey, respectively. NPs obtained from turmeric extract had 6.08 nm particle size. The isoelectric points of CeO2-NPs were about 4 when the starting material was blossom and pine honey. For the chestnut honey and turmeric as starting material, the isoelectric points of NPs were about 6 and 9.5, respectively. The band gap energies changed between 2.80-3.21 eV. All green synthesised nanoparticles exhibited high antioxidant activities according to the DPPH method, changing between 32.4 and 64.5 μg ml−1 as IC50 values. Activity values increased in the order of blossom, pine, chestnut honey, and turmeric. All synthesised NPs reflected the literature antioxidant rankings of the starting natural materials. Thanks to the strong redox property of the CeO2-NPs, high degradation efficiencies (between 83.9 and 93.4%) were obtained for MB under UV light irradiation. The natural starting materials used created differences in the physical and activity properties of the NPs. Green synthesis of CeO2-NPs with new natural materials will expand their usage areas.

Published: March 2022

Abstract
This article analyzes the direct current and small-signal parameters of MgZnO/ZnO (MZO) HEMT for microwave application. Further, the impact of the MgO spacer layer on the microwave performance parameters such as transconductance (g
m), cut-off frequency (f
T), maximum oscillation frequency (f
max) and Johnson’s figures of merit (J-FOM) of MZO HEMT has been analyzed. MZO HEMT with MgO spacer results in the enhanced values of two-dimensional electron gas (2DEG) density of 7.2 × 1013 cm−2 and g
m of 91 mS mm−1. The values of f
T and f
max exhibit 3-fold enhancement to 5.57 GHz and to 7.8 GHz, respectively, and J-FOM is increased by 2.93 times with the introduction of MgO spacer layer in HEMT structure. Moreover, the impact of MgO spacer is studied on the off-state breakdown mechanism of MZO HEMT. The off-state breakdown voltage (V
br) of MZO HEMT is ∼25 V higher than that for MZO HEMT with an MgO layer. Therefore, there is a trade-off between the microwave performance and the device off-state breakdown voltage. This work is significant for the development of large-area and cost-effective ZnO-based HEMTs for microwave applications.
A Rationale for Micro-textured Breast Implant Augmentation
Authors: Chiemi Julia A , Kelishadi S Sean 
Published: March 2022

Abstract

Background
Textured breast implants have been used in aesthetic breast surgery to decrease rates of malposition and capsular contracture. Recent concerns regarding breast implant-associated anaplastic large cell lymphoma (BIA-ALCL)’s link to textured devices have prompted many physicians to reevaluate their use.

Objectives
The authors aimed to create an algorithm for when to use smooth vs micro-textured breast implants and provide their rationale for when micro-textured implants may be more beneficial.

Methods
In total, 133 patients received primary augmentations performed by a single surgeon from January 2018 to December 2020; 84 patients received smooth implants and 49 patients received micro-textured implants. All surgeries were performed in the dual plane using an inframammary incision. Implant-related complications and scar malposition were recorded and compared between groups.

Results
No significant difference in the prevalence of implant-related complications was found (3.57% for smooth devices and 2.04% for micro-textured devices [P-value 0.621257; 95% CI −0.06100 to 0.007467]). There were no cases of BIA-ALCL. A comparison of scar malposition rates between the smooth and micro-textured groups also revealed no statistically significant difference (15.4% for smooth devices and 8.16% for micro-textured devices [P-value 0.226156; 95% CI −0.1200 to 0.007467]). Patients in the micro-textured group proportionately had more anatomical risk factors for malposition.

Conclusions
Micro-textured breast implants continue to be a safe and effective choice for patients. Micro-textured implants show a trend toward decreased scar malposition, although not statistically significant. Patients at high risk for malposition with micro-textured breast implants give similar results to patients at average risk for malposition with smooth implants.

Published: March 2022

Abstract
Mutation detection is of major interest in molecular diagnostics, especially in the field of oncology. However, detection can be challenging as mutant alleles often coexist with excess copies of wild-type alleles. Bridged nucleic acid (BNA)-clamp PCR circumvents this challenge by preferentially suppressing the amplification of wild-type alleles and enriching rare mutant alleles. In this study, we screened cationic copolymers containing nonionic and anionic repeat units for their ability to (i) increase the Tm of double-stranded DNA, (ii) avoid PCR inhibition, and (iii) enhance the suppression of wild-type amplification in BNA-clamp PCR to detect the KRAS G13D mutation. The selected copolymers that met these criteria consisted of four types of amines and anionic and/or nonionic units. In BNA-clamp PCR, these copolymers increased the threshold cycle (Ct) of the wild-type allele only and enabled mutation detection from templates with a 0.01% mutant-to-wild-type ratio. Melting curve analysis with 11-mer DNA–DNA or BNA–DNA complementary strands showed that these copolymers preferentially increased the Tm of perfectly matched strands over strands containing 1-bp mismatches. These results suggested that these copolymers preferentially stabilize perfectly matched DNA and BNA strands and thereby enhance rare mutant detection in BNA-clamp PCR.
Non-ST elevation myocardial infarction and ischaemic cardiomyopathy due to extrinsic tumour compression of left internal mammary artery graft-obtuse marginal with fibrosis due to chest wall radiation: a case report
Authors: Mian Mahnoor , Taylor David , Lo Sidney , Leung Melissa 
Published: March 2022

Abstract

Background
Cardiovascular disease and cancer remain the most prevalent conditions worldwide. The relationship between the two is becoming increasingly recognized, with both sharing similar risk factors. Currently, there are no guidelines or substantial data for the management of this subset of patients. This case presents the management of a patient with advanced malignancy and ischaemic cardiomyopathy, exploring the difficult decision making process for revascularization, ensuring an individualized approach is used for each patient.

Case summary
A 68-year-old man with Stage II lung cancer and overall poor prognosis with multiple comorbidities limiting his functional status presented with a non-ST elevation myocardial infarction and ischaemic cardiomyopathy due to extrinsic tumour compression and left internal mammary artery graft-obtuse marginal fibrosis due to chest wall radiation. He had a prolonged admission with the heart team discussions regarding optimal management. He subsequently underwent percutaneous coronary intervention to his native left circumflex chronic total occlusion. He was discharged home on dual antiplatelet and heart failure therapy.

Discussion
This case reflects that the management of patients with cancer and coronary artery disease is complex. Many factors including patient comorbidities adversely impact on prognosis, and treatment goals need to be clearly defined. The evidence in the area is lacking but continues to grow; however, the care for such patients needs to be individualized.
Change in Doctoral Dissertation Topics in Forest Resources from US Universities Over Four Decades
Authors: Wagner Robert G , Bellisario Kristen M , Kong Ningning N 
Published: March 2022

Abstract
Changes in forest resources expertise from 1978 to 2017, as measured by annual number of doctoral dissertations published on twenty topics, were examined. Using the ProQuest Dissertations and Theses Global database, titles and abstracts from 11,530 dissertations produced by fifty-six universities in the United States were selected. Automated content analysis and latent Dirichlet allocation were used to identify the optimal number of topic groupings among 7,742 dissertations that met selection criteria. Substantial differences were found in the pattern of publication among the twenty topics over time. The number of dissertations related to forest growth and silviculture; tree seedling propagation, physiology, and regeneration; and forest soil nutrients, ecology, and management declined over the past two decades. Dissertations related to forest wildlife management, including terrestrial wildlife ecology and management; wildlife food and nutrition; and fish ecology and management also declined during the same period. The number of dissertations in the fields of forest policy, politics, and social science; forest modeling, biometrics, and statistics; wood science; forest vegetation ecology; and avian ecology increased during the four decades. Dissertations published in the fields of forest economics, and forest entomology and pathology, remained relatively stable.
Study Implications: We found decreasing production of doctoral dissertations focused on applied forest and wildlife management topics in recent decades. Declining doctoral-level expertise in applied fields after the early 2000s suggest that there may be reduced capacity to address practical problems facing both forest and wildlife managers. This decline also suggests that finding university instructors qualified to teach more applied forest and wildlife courses may have been more difficult over the past decade and possibly into the future. Our analysis indicated that the increased number of dissertations in adjacent sciences supporting forest resources has substantially increased capacity in these areas.
Pediatric Office Emergency Preparedness
Authors: Spanos Stephanie 
Published: March 2022

Objective
Preparation is vital to improve resuscitation outcomes for children presenting to the primary care office with emergent conditions. Previous literature has provided recommendations for medications, equipment, and skills necessary to provide appropriate care. Most studies thus far demonstrated offices are unprepared according to those recommendations. We sought to provide an intensive emergency training and preparation curriculum to local primary care pediatric offices to improve their emergency readiness.

Methods
Using a high-fidelity manikin, a simulation instructor team visited several offices and trained teams including physicians, nurse practitioners, nurses, medical assistants, front desk staff, and billing/management staff. Two emergency resuscitation simulations were performed per session with education after each scenario. The instructor team taught procedures, provided teamwork training, and provided feedback on medications, equipment, and resuscitation priorities.

Results
Eight primary care pediatric offices participated in the curriculum, 36 training sessions were conducted, and 229 staff were trained. Numerous issues with medications, equipment, teamwork dynamics, and pediatric emergency resuscitation were revealed. There was always significant improvement from the first to the second simulation in each session.

Conclusions
Our intensive emergency training and preparation curriculum experience with local primary care pediatric offices highlighted discrepancies between the perceived level of office preparedness and actual experience during a simulated emergency. Office staff felt more prepared for an emergency after the training, and office medications and equipment were re-evaluated to provide a more efficient and effective resuscitation for their patients.

Published: March 2022

Purpose
The aim of this study was to investigate the role of 18F-FDG PET/CT in predicting pathological prognostic factors, including tumor type and International Federation of Gynecology and Obstetrics (FIGO) score, in gestational trophoblastic disease (GTD).

Methods
Retrospective monocentric study including 24 consecutive patients who underwent to 18F-FDG PET/CT from May 2005 to March 2021 for GTD staging purpose. The following semiquantitative PET parameters were measured from the primary tumor and used for the analysis: maximum standardized uptake value (SUVmax), SUVmean, metabolic tumor volume (MTV) and total lesion glycolisis (TLG). Statistical analysis included Spearman correlation coefficient to evaluate the correlations between imaging parameters and tumor type (nonmolar trophoblastic vs postmolar trophoblastic tumors) and risk groups (high vs low, defined according to the FIGO score), whereas area under the curve (AUC) of the receiver operating characteristic (ROC) curve was used to assess the predictive value of the PET parameters. Mann-Whitney U test was used to further describe the parameter’s potential in differentiating the populations.

Results
SUVmax and SUVmean resulted fair (AUC, 0.783; 95% confidence interval [CI], 0.56–0.95) and good (AUC, 0.811; 95% CI, 0.59–0.97) predictors of tumor type, respectively, showing a low (ρ = 0.489, adjusted P = 0.030) and moderate (ρ = 0.538, adjusted P = 0.027) correlation. According to FIGO score, TLG was instead a fair predictor (AUC, 0.770; 95% CI, 0.50–0.99) for patient risk stratification.

Conclusions

18F-FDG PET parameters have a role in predicting GTD pathological prognostic factors, with SUVmax and SUVmean being predictive for tumor type and TLG for risk stratification.
