Reflection on Contradictory Learning Methods and Identity Formation in a New Academic Life Setting
Authors: Rosli Aishah , Shahul Hamid Mohamed Yusuf
Published: January 2022

Lecturers new to the academic life setting normally face similar types of challenges. These challenges were intensified for new lecturers starting their careers in the academic setting during the COVID-19 pandemic, when classes were conducted online. Student-centered learning has been the focus in engineering education recently, but many of the current lecturers have never experienced this method of learning as students, resulting in unfamiliarity and inexperience in conducting classes using this method of teaching. Our experiences as two new lecturers starting our academic careers during the pandemic using both the student-centered learning method and teacher-centered learning method in different classes are reported through collaborative autoethnographic methods. Both of our reflections revealed that stark differences can be seen as an effect of the teaching method, concluding that the student-centered learning method is superior to the traditional teacher-centered learning method. However, applying the former method also has some challenges. To overcome these challenges faced by new lecturers, some action plans have been listed for future improvement, which could be very meaningful and useful to other new lecturers as well as educators new to applying the student-centered learning method.

Published: January 2022

Epistemology is a branch of philosophy, a study of how a person knows and knowing. Engineering epistemology is one of the new disciplines in engineering education research. Unfortunately, little research has been done on engineering education. In this paper, epistemology is discussed in the general context then, specifically for the engineering education context. Furthermore, the engineering epistemology framework and instrument to investigate engineering epistemology among engineering educators and students have been presented. Theory for knowledge development has been discussed in general and how that developmental model is important for higher education. Finally, epistemology in teaching and learning has been introduced in the context of engineering educators and engineering students. In summary, engineering educators’ epistemology will shape future engineers based on their class design. Therefore, developing engineering students from dualists to commitments of the relativist is very important. Finally, suggestions for engineering faculty management in developing engineering educators and engineering students for a better teaching and learning experience are provided.
Building Energy Codes: Reviewing the Status of Implementation Strategies in the Global South
Authors: Gaum Tariene , Laubscher Jacques
Published: January 2022

The public understanding of climate change, methods, mitigation, adaptation and the reason behind it have been investigated in developed countries. The current knowledge levels in the Global South remains limited, this while countries forming part of the Global South are more vulnerable to resultant effects of global warming. This requires the urgent attention by both citizens, who lack relevant information as well as decision makers lacking environmental literacy to establish long-term sustainable strategies. With just 9 years left, the probability of achieving the Sustainable Development Goals (SDGs), is unlikely and will require the complete redevelopment of the building sector. Focusing on the built environment, this paper uses contemporary definitions of the Global South to establish the contribution, significance and lack of energy efficiency mechanisms in the face of climate change. A combination of literature, desk research and data gathering from various sources are employed to establish the contribution of the Global South built environment to climate change. Using Carbon Dioxide (CO₂) emissions, 2050 urban population figures and distinctive climatic regions as basis, this study selected the largest role players to establish the status, extent and efficacy of building energy codes. The review point towards a built environment lacking the necessary building energy codes, with approximately 47% of selected Global South countries not implementing any form of building energy efficiency regulations or related policies. As part of the recommendations, Global South countries lacking the necessary regulations are encouraged to revise, update or adopt possible best practice standards from relevant countries that implement mandatory building energy codes. This study aims to address the gap in knowledge, establish a way forward and facilitate a larger implementation of building energy codes and strategies in the Global South
Personality and Walkability: Predicting Walking Behaviour in Urban Settings using the Higher Order Factors of the Big Five amongst Malaysian Adults
Authors: Bashri Ahmad Syukri , Che Amat Rohayah
Published: January 2022

Walkability has now been a popular policy to be adopted in the city centre as traffic congestion and inefficient public transportation have affected the mobility of the urban users prior to the pandemic. The pandemic has paved more efforts to improve the design of urban spaces to increase walkability in the cities. In the attempt to predict walking activity amongst Malaysian adults psychologically, a personality test using Big Five Aspect Scales (BFAS) was conducted in relation to individual walking frequency in urban settings.  Structural equation modelling (SEM) was used to analyze the predicting capacity of personality constructs control by general intelligence in relation to walking behaviour. The results show that the higher order meta-traits of the big five personality traits which are Stability (Neuroticism, Agreeableness, and Conscientiousness) and Plasticity (Extraversion and Openness to Experience) can be used as a reliable predictor for individual walking behaviour. As hypothesized, walking behaviour amongst Malaysians was characterized by reversed Stability (r = -.58) and high Plasticity (r = .76). The implication suggested the necessity of cognitive navigability and design predictability metrics of urban design cognitive performance in influencing the psychological factor of walking behaviour
Barriers to Institutional Investment in Rental Housing: A Systematic Review of Market Risks
Authors: Swanzy-Impraim Samuel , Ge Xin Janet , Mangioni Vincent
Published: January 2022

Housing practitioners and policy experts are advocating for an expansion in rental housing supply in contemporary cities around the world. The objective is to convince institutional investors to include rental housing investment in their investment portfolio to contribute to boosting housing supply. Unfortunately, the rental sector is characterized by numerous uncertainties and challenges, making it unattractive to institutional investors. With the growing attention to institutional investors in various housing market contexts, an understanding of the market risks (also known as barriers), is useful to inform future research and policymaking. Using a systematic literature review methodology, this paper synthesizes the extant literature on the market risks inhibiting institutional investment in rental housing. Findings reveal the following barriers: low profitability, non-progressive rent control policies, unclear target group for rented projects, poor landlord-tenant relations, inadequate property management and unreliable property market information. Among all the barriers identified, low profitability and inadequate property management had great influence on their investment decision. Firstly, institutional investors perceive rental housing investment as less profitable and unattractive in terms of project performance. Secondly, the lack of supporting structures for the property management sector contributes to derailing rental yields. The review also finds that the target group for rental projects are often vague especially for projects under government assistance. The rental sectors in many countries are confronted with numerous problems, some of which greatly inhibit institutional investors from investing in the rental asset. This paper concludes that, although the idea of expanding rental housing supply seems laudable, ignoring these problems may be detrimental to housing markets in the long run. Rental markets in many countries are volatile, and thus not ready to receive institutional investors fully into the sector. An expanded rental sector could be advanced if policy makers take the appropriate steps to resolve the identified challenges. Adequate structural preparations must also be made for large scale rental housing supply.

Published: January 2022

After 30 years of war in Sri Lanka, the demand for real estate has increased tremendously across the nation. Similarly, numerous real estate sub-sectors have avidly participated in the worldwide boom. However, with failures and poor functioning of many investment projects, the industry's risk management reputation has been put in jeopardy, followed by the coronavirus (COVID-19). Though it is less popular among Sri Lankan property developers, risk management strategies in development projects have become a pressing requirement. This paper's goal is to look at commercial property development risk elements from the perspective of a real estate developer in relation to Social, Economic, Environmental, Technological, Political, and Pandemic Risks. The research first evaluates risk variables using a super decision software model based on the Analytic Hierarchy Process (AHP), then prioritizes the most important risk factors, and lastly examines effective risk management measures for successful real estate developments. The data collection has been carried out using interviews through telephone conversations with the help of a structured questionnaire. Accordingly, 35 risk factors have been assessed altogether. For the three projects, the synthesized values were 1.0000, 0.510763, and 0.604037, respectively. Based on the analysis of superMatrix calculation, project A is regarded as the best alternative project in such circumstances. Pandemic Risk, Economic Risk, and Political Risk have all had a significant impact on the primary risk criteria. Therefore, COVID-19 Pandemic Risk Emergence, Workforce Availability, Duration, Delays in Council Approval/License Approval Process and Natural Disaster Impact were identified as the highest influenced sub-risk factors. Identifying the risk factors on this avenue will also help in making better investment decisions while increasing the unpredictable nature of the real estate field and future satisfaction of loan team investment goals within the country.

Published: January 2022

Past studies on the mortgage market of Ghana evidenced that absence of long-term sources of housing funds, low-income levels, macroeconomic instability, inability to assess the creditworthiness of prospective mortgagors among others plague the development of Ghana’s mortgage market. Therefore, this study was conducted to evaluate the relationship between challenges militating against mortgage finance and benefits of mortgage acquisition in Ghana. Questionnaires were used to elicit responses from respondents. Convenience sampling technique was used to select one hundred (100) respondents comprising staff at SSNIT Head Office in Accra, SSNIT contributors, beneficiaries of SSNIT funds, mortgage applicants, owners and occupants of SSNIT flats. Mean score ranking, Cronbach’s Alpha coefficient, one sample t-test and Partial Least Square Structural Equation Modeling (PLS-SEM) were the analytical tools adopted. Dollarization of mortgage markets, access to funding for the scheme, macroeconomic instability and inability to assess creditworthiness of mortgage applicant were the most significant challenges. The most significant benefits were: (1) increase in the rate of house construction; (2) ability to provide a relatively low-interest credit; (3) capacity to mitigate housing deficits; and (4) capability to provide a relatively long-term credit for housing. Structural Equation Model was developed to evaluate the relationship between the challenges and benefits. The study is beneficial to stakeholders such as policymakers, financial institutions, Ghana Real Estate Developers Association (GREDA) and SSNIT contributors. This work is a pioneering study in Ghana on the relationship between challenges SSNIT encounters in mortgage financing and benefits of acquiring mortgage facilities with the assistance of SSNIT.

The improvements in wind energy infrastructure have been a constant process throughout many decades. There are new advancements in technology that can further contribute toward the prognostics and health management (PHM) in this industry. These advancements are driven by the need to fully explore the impact of uncertainty, quality and quantity of data, physics-based machine learning (PBML), and digital twin (DT). All these aspects need to be taken into consideration to perform an effective PHM of wind energy infrastructure. To address these aspects, four research questions were formulated. What is the role of uncertainty in machine learning (ML) in diagnostics and prognostics? What is the role of data augmentation and quality of data for ML? What is the role of PBML? What is the role of the DT in diagnostics and prognostics? The methodology used was Preferred Reporting Items for Systematic Review and Meta-Analysis. A total of 143 records, from the last five years, were analyzed. Each of the four questions was answered by discussion of literature, definitions, critical aspects, benefits and challenges, the role of aspect in PHM of wind energy infrastructure systems, and conclusion.

Published: January 2022

The ability to endure starvation is important for predatory mite survival and its effectiveness as biological control agent. We studied the longevity and functional response of the prodator mite Neoseiulus californicus (McGregaor) under starvation stress. N. californicus individuals were treated as three groups: the mites were provided with nothing (group I), with fresh bean leaves (group II), and with water (group III) to the larvae, protonymphs, deutonymphs, adult males and females. Functional response of N. californicus to Tetranychus urticae Koch eggs was evaluated after starvation for 0 h, 24 h, 48 h, and 72 h. Results showed that all life stages of N. californicus in group III had the longest survival time among the three groups. Adult females had the strongest ability to endure starvation with a mean survival time of 8.16 d. Females had the ability to lay eggs, but the number of eggs laid was less than a mean of 1.2 eggs per female in the three starvation groups. N. californicus exhibited a Holling’s Type II functional response at all hunger levels. The handling time (Th) and attack rate (α) of the predator were not significantly different in all hunger levels. Predation rate of starved 0 h to 72 h initially increased and then decreased. The highest predation rate was recorded when the predators were starved for 24 h.

Published: January 2022

In this study two species of soft ticks belonging to the genus Ornithodoros were recorded in three areas in the province of Corrientes, Argentina. Four larvae were identified as Ornithodoros hasei (Schulze, 1935) on Molossus molossus (Molossidae) in Paraje Tres Cerros (Department of San Martín), while 56 larvae were identified as Ornithodoros sp. cf. O. mimon Kohls, Clifford & Jones, 1969 on Eptesicus furinalis and Myotis levis (Vespertilionidae) in Paraje Galarza (Department of Santo Tomé) and Colonia Carlos Pellegrini (Department of San Martín). These last two locations are found within the Esteros del Iberá eco-region.  The known distribution range of O. hasei and O. cf. O. mimon is expanded to include the province of Corrientes. Two new ectoparasite-host associations were recorded for Argentina between O. hasei on M. molossus and O. cf. O. mimon on M. levis. The morphological differences together with the results of the phylogenetic analysis show that O. hasei presents genetic similarity with specimens from Brazil, and in Argentina, with ticks from Santa Fe. Instead, Ornithodoros sp. cf. O. mimon recorded in Corrientes and Uruguay belong to a different taxon than the O. mimon recorded in Brazil and Santa Fe, Argentina. Based on this, O. mimon should be considered a complex of species in which the specimens from Corrientes are provisionally considered as Ornithodoros sp. cf. O. mimon until their taxonomic status can be determined.

Published: January 2022

Haemaphysalis qinghaiensis is an endemic species and mainly inhabiting in the northwestern plateau of China, which can transmit many zoonotic pathogens and cause great harm to animals. In this study, the complete mitochondrial genome (mitogenome) of H. qinghaiensis was assembled through the Illumina HiSeq platform. The mitogenome was 14,533 bp in length, consisting of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and 3 noncoding regions (NCRs). The bias towards a high A+T content with 77.65% in mitogenome of H. qinghaiensis. The rearrangement of mitochondrial genes in H. qinghaiensis was consistent with other hard ticks. The phylogenetic analysis based on the concatenation of 13 PCGs from 65 tick mitogenomes showed that the H. qinghaiensis was clustered into a well-supported clade within the Haemaphysalis genus. This is the first complete mitogenome sequence of H. qinghaiensis, which provides a useful reference for understanding of the taxonomic and genetics of ticks.

Authors: Doma Kenji , Engel Alexander , Connor Jonathan , Gahreman Daniel
Published: January 2022

Purpose: This study examined the effect of providing knowledge of results (KR) with, and without, promotion- and change-oriented feedback on repeated-sprint ability in swimmers. Methods: Twenty-nine male and female swimmers (age = 16 [1] y, height = 1.74 [0.07] m, body mass = 61.0 [8.4] kg) were randomly allocated into 2 different feedback conditions, or a condition without feedback (NoFb), as a crossover, repeated-measures design. In one feedback condition, the swimmers were provided with lap completion times as KR. The other feedback condition was athlete-driven, where the swimmers were asked to estimate their lap completion times, and the investigators responded on whether their actual sprint times were faster (promotion-oriented), slower (change-oriented), or the same. Results: The results showed significantly faster average completion times during the repeated-sprint swim protocol in the athlete-driven KR (P = .014) and KR condition (P = .023), when compared with the NoFb condition. However, significantly faster best completion time was only found in the KR condition (P = .012), when compared with the NoFb condition. Furthermore, the stroke rate was significantly greater during the athlete-driven KR (P = .009) and KR (P = .021) conditions, when compared with the NoFb condition. Conclusions: The KR condition exhibited the greatest benefit for improving several swimming performance measures during a repeated-sprint protocol, and the increase in stroke rate may have contributed to this performance enhancement. Thus, it is recommended that swimmers receive lap completion times during repeated-sprint training sessions to optimize training quality.

Published: January 2022

Burn-out among US physicians has been on the rise in the past few decades. Similarly, rheumatologists in the Geisinger Health System have experienced professional dissatisfaction through significant administrative burden and in-basket work. We embedded pharmacists into our rheumatology team in 2019 with the aim of reallocating medication refills to pharmacists, trained professionals in this domain, to help reduce physician workload and burn-out and increase satisfaction. Protocol-driven medication refill parameters per the American College of Rheumatology guidelines and new refill workflows for disease-modifying antirheumatic drugs (DMARDs) and non-DMARDs were created for use by our rheumatology pharmacists. Monthly data on medication refill volume and time saved for rheumatologists were collected from 1 January 2019 to 31 March 2021. Statistical analysis was completed via Shewhart p-charts. The volume of refills by rheumatologists decreased by 73% and the time saved per month for all the rheumatologists increased to 41.5 hours within 6 months. Physicians’ feedback was obtained via anonymous electronic surveys preintervention and postintervention. The statistical difference between the presurveys and postsurveys was calculated via two-tailed unpaired t-testing. It demonstrated reduced burn-out and improved workplace satisfaction. This study showed that the integration of rheumatology pharmacists into our practice can help improve the work life of the rheumatologists. It is important for physicians’ well-being to practice at the top of their scope and achieve work–life balance.
ADG: automated generation and evaluation of many-body diagrams
Authors: Tichai A. , Arthuis P. , Hergert H. , Duguet T.
Published: January 2022

The goal of the present paper is twofold. First, a novel expansion many-body method applicable to superfluid open-shell nuclei, the so-called Bogoliubov in-medium similarity renormalization group (BIMSRG) theory, is formulated. This generalization of standard single-reference IMSRG theory for closed-shell systems parallels the recent extensions of coupled cluster, self-consistent Green’s function or many-body perturbation theory. Within the realm of IMSRG theories, BIMSRG provides an interesting alternative to the already existing multi-reference IMSRG (MR-IMSRG) method applicable to open-shell nuclei. The algebraic equations for low-order approximations, i.e., BIMSRG(1) and BIMSRG(2), can be derived manually without much difficulty. However, such a methodology becomes already impractical and error prone for the derivation of the BIMSRG(3) equations, which are eventually needed to reach high accuracy. Based on a diagrammatic formulation of BIMSRG theory, the second objective of the present paper is thus to describe the third version (v3.0) of the code that automatically (1) generates all valid BIMSRG(n) diagrams and (2) evaluates their algebraic expressions in a matter of seconds. This is achieved in such a way that equations can easily be retrieved for both the flow equation and the Magnus expansion formulations of BIMSRG. Expanding on this work, the first future objective is to numerically implement BIMSRG(2) (eventually BIMSRG(3)) equations and perform ab initio calculations of mid-mass open-shell nuclei.

Prevention of Nursing Interruption Disputes in Obstetrics and Gynecology Based on Nursing Process Reengineering
Authors: Xuejiao Zhao , Xuejiao Wang
Published: January 2022

During the nursing administration process, including preparation, management, and documentation, there is a high proportion of work interruption that results in nursing administration errors that consequently affect the safety of patients, increase the occurrence of nursing risks, and cause adverse reactions. To investigate the impact of nursing on drug withdrawal disputes in obstetrics and gynecology and reduce medical disputes are of great importance. In this study, documents related to medical disputes are collected and linked to relevant professional information systems for data collection and consultation. The patients are divided into groups and treated with different nursing methods, and then the correlation between nursing methods and disputes in different groups is computed. The results show that, based on the proposed nursing process, medical disputes caused by the cessation of nursing can be effectively reduced. Compared with traditional nursing methods, when the proposed nursing procedures are followed, the dispute rate is reduced by more than 10% and the possibility of serious disputes is also reduced with a reduction rate of about 15%. This shows that, based on the proposed nursing process, reengineering can play an effective preventive role in stopping obstetrics and gynecology nursing disputes.

Quantitative evaluation is an important part of enterprise diagnosis, which promotes the scientific and modern management of enterprises. At present, the existing enterprise management evaluation methods cannot complete the mining of enterprise index data, which leads to large error and low significance coefficient in enterprise management evaluation. Therefore, the application of data mining in enterprise lean management effect evaluation is put forward. The process and main functions of data mining are analyzed; data mining algorithm is used to establish the evaluation index system of lean management effect and calculate the index weight. Using the association rules method in data mining, according to the parameters of enterprise lean management level evaluation index and weight value, through the fuzzy set transformation idea, the fuzzy boundary of each index and factor is described by the membership degree, the fuzzy judgment matrix is constructed, and the final evaluation result is obtained by multilayer compound calculation. Experimental results show that this study has a high significance coefficient, and the proposed evaluation method of enterprise lean management effect has ideal accuracy and short time consumption. In practical application, the cumulative contribution rate is higher and has higher stability.
Optimized Production of Biodiesel Using Internet of Things Sensed Temperature with Hybrid Particle Swarm Optimization
Authors: Loganathan G. , Kannan M.
Published: January 2022

Biofuel production offers a non-fossil fuel that can be utilized in modern engines without any redesign. Regardless of receiving rising attention, many researchers have explored microalgae-based biofuel production and found biodiesel production is cost-effective compared to petroleum-centered conventional fuels. The primary reason is that the lipid accumulation of microalgae is possible. An efficient technique is proposed for optimized biodiesel manufacturing with microalgae through an IoT device with the hybrid particle swarm optimization (HPSO) algorithm for elapsing such drawbacks. First, the component of biodiesel is determined. Then, from the components, the temperature value is sensed through the IoT device. Based on the obtained temperature, the reaction parameters are optimized with HPSO to increase productivity and reduce cost. Finally, we observed performance and comparative analysis. The experimental results contrasted with the existent particle swarm optimization (PSO) and genetic algorithm (GA) concerning iteration’s temperature, concentration, production, and fitness. The present HPSO algorithm has differed from the existing PSO and GA concerning IoT sensed temperature and production function. Fitness value and instance concentration are the performance parameters. It varies based on the iteration values. Thus, the proposed optimized biodiesel production is advanced when weighed down with the top-notch methods.
Diagenetic Fluid and Its Impact on Sandstone Reservoirs in the Southern Boxing Sag, Dongying Depression, Bohai Bay Basin, China

Published: January 2022

Diagenesis typically exerts a crucial impact on the formation of high-quality sandstone reservoirs in the Eocene Shahejie Formation, Dongying Depression. To better understand the formation process of petrophysical properties, this research conducts petrographic and geochemical analyses to investigate the nature of diagenetic fluids. Petrographic observations suggest that the dominant cements are carbonate, authigenic quartz, and clay minerals, accompanied with the dissolution of feldspar and calcite. The homogenization temperature of aqueous inclusions in quartz overgrowth usually exceeds 90°C corresponding to the maturity of organic matter. Quartz overgrowths contain higher amounts of CaO and Al2O3 than detrital quartz. This indicates that the siliceous fluid mainly originates from the dissolution of feldspar. Moreover, the conversion of clay minerals also provides trace amounts of silica into pore water during the burial process. Carbonate cements consist of early-stage calcite as well as late-stage Fe-calcite and ankerite. Calcite with relatively higher MnO proportions shows yellow luminescence and dissolution signs. Fe-calcite and ankerite cements have a higher homogenization temperature than that of quartz overgrowth and mainly concentrate in FeO and MgO as well as contain a small amount of Na+, K+, and Sr2+. The rare earth element (REE) pattern of bulk mudstone and carbonate cements as well as C–O isotopic evidences indicate that the diagenetic fluids of carbonate cementation are primarily controlled by the adjacent mudstone, whereas mineral dissolution and altered clay minerals in sandstone provide additional cations for the local reprecipitation of late-stage carbonate. Therefore, diagenetic fluids within sandstone reservoirs are typically subject to alkaline–acid–alkaline conditions and are influenced by internal sources in a closed system. Compaction significantly reduces the pore space of sandstone reservoirs in the Boxing Sag. Carbonate cementation further increases the complexity of pore structure and obeys the principle of mass balance.

Authors: Zhang Wanxia , Liu Bo , Tsai Sang-Bing
Published: January 2022

Digital reading promotion service is a service way for libraries to provide readers with a series of digital resources, enjoy the service functions, and share the experience of using them in various digital reading platforms, which is to meet the reading interests and reading needs of more readers, and is also the focus of the current library work. In the era of new media, the characteristics of digital reading are subtly changing the readers’ needs for reading environment, reading content, and reading style. Libraries should keep pace with the development of the times and provide readers with diversified, intelligent, and targeted digital reading platforms. The digital reading platform should continuously improve the digital reading service functions, broaden the service scope and dissemination channels, and finally realize the diversification, interest, and intelligence of digital reading service. This paper takes the digital reading platform of libraries in the region as the research theme and carries out research work on libraries. The province is divided into three regions according to the geographical map: southeastern region, central region, and northwestern region. The digital reading platforms of 14 prefecture-level public libraries and 58 libraries of higher education institutions in each region were accessed. Firstly, we check the construction of digital resources within the library websites, secondly, we count the opening of digital reading platform functions, and finally, we check the opening of digital reading platforms. Through the research, it is found that there are problems of unbalanced distribution of digital reading resources in regional libraries; unattractive design of readers’ interface and inadequate reading service functions; lack of continuous training of readers’ guidance; insufficient publicity and promotion; low efficiency of staff in responding to consultation; and low degree of platform openness and weak awareness of sharing. Finally, the problems found in the research are summarized, and the solution measures for the regional digital reading platform are proposed. Libraries in the digital era should give priority to systems that can manage all library resources comprehensively and effectively, adapt to more flexible library workflows, and enable libraries to provide better services to users.
In Situ Monitoring of Corrosion under Insulation Using Electrochemical and Mass Loss Measurements
Authors: Yang Mingzhang , Liu Jing
Published: January 2022

Corrosion under insulation (CUI) refers to the external corrosion of piping and vessels when they are encapsulated in thermal insulation. To date, very limited information (especially electrochemical data) is available for these “difficult-to-test” CUI conditions. This study was aimed at developing a novel electrochemical sensing method for in situ CUI monitoring and analysis. Pt-coated Ti wires were used to assemble a three-electrode electrochemical cell over a pipe surface covered by thermal insulation. The CUI behavior of X70 carbon steel (CS) and 304 stainless steel (SS) under various operating conditions was investigated using mass loss, linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS) measurements. It was found that both the consecutive wet and dry cycles and cyclic temperatures accelerated the progression of CUI. LPR and EIS measurements revealed that the accelerated CUI by thermal cycling was due to the reduced polarization resistance and deteriorated corrosion film. Enhanced pitting corrosion was observed on all tested samples after thermal cycling conditions, especially for CS samples. The proposed electrochemical technique demonstrated the ability to obtain comparable corrosion rates to conventional mass loss data. In addition to its potential for in situ CUI monitoring, this design could be further applied to rank alloys, coatings, and inhibitors under more complex exposure conditions.

Published: January 2022

Stray current directly affects the regular operation of electrical equipment and facilities in the subway DC traction power supply system. Therefore, it is worthwhile to study the stray current distribution characteristics during train operation and the quantitative corrosion of buried pipelines. This paper introduces the traction characteristics of power carriages and power wheelsets of subway vehicles into the DC traction process. A finite element model considering the dynamic distribution of stray current under the actual operation of subway vehicles is established. The interference characteristics of stray current and the contribution of power sources under the multiparticle model are analyzed. The rail insulation damage caused by long service time and the quantitative calculation of rail and buried pipeline corrosion is considered. The model results show that the stray current in the buried pipeline under the multiparticle model is more accurate and more suitable for the protection in the actual subway. The quantitative corrosion of the buried pipeline is stronger than the partial insulation damage environment when the rail is not insulated. The rail and buried pipeline corrosion at both ends of the insulation damage position is relatively severe. The stray current distribution model established in this paper gives full play to the solution advantages of the finite element method and provides a new idea for the quantitative calculation of buried pipeline corrosion.

Autism spectrum disorder is an inherited long‐living and neurological disorder that starts in the early age of childhood with complicated causes. Autism spectrum disorder can lead to mental disorders such as anxiety, miscommunication, and limited repetitive interest. If the autism spectrum disorder is detected in the early childhood, it will be very beneficial for children to enhance their mental health level. In this study, different machine and deep learning algorithms were applied to classify the severity of autism spectrum disorder. Moreover, different optimization techniques were employed to enhance the performance. The deep neural network performed better when compared with other approaches.

Ruxolitinib is an FDA-approved treatment of intermediate- and high-risk myelofibrosis. In the phase 3 COMFORT studies, ruxolitinib reduced spleen volume in patients with myelofibrosis, with a median time to response of 3 months. However, nearly 20% of patients discontinued by month 4 with few treatment options available following discontinuation of ruxolitinib treatment. In this study, 2 independent patient care data sources were queried (Cardinal Health Oncology Provider Extended Network [OPEN] and HealthCore Integrated Research Environment [HIRE®]), and a retrospective review of medical charts was conducted. Patients aged ≥18 years with a diagnosis of myelofibrosis (primary or secondary), use of ruxolitinib for myelofibrosis, and documented physician-directed ruxolitinib interruption were included. Among 26 included patients, pre-interruption median (interquartile range [IQR]) ruxolitinib treatment duration was 123 (57–391, OPEN) and 110 (37–148, HIRE) days. Half the patients interrupted treatment within 3 months, commonly for adverse events (42% and 71%, respectively). After restarting ruxolitinib, median (IQR) re-treatment duration was 196 (54–553) and 166 (108–262) days, respectively. Consistent with previous reports, symptoms and spleen size improved in (OPEN/HIRE) 45%/43% and 40%/33% of evaluable patients, respectively. Further studies investigating the management of dose modifications and interruptions are needed to optimize benefit from ruxolitinib therapy.

Oral finasteride represented a breakthrough for treatment of male pattern hair loss (MPHL), with clinical studies having demonstrated high efficacy of treatment and a favorable safety profile. And yet, fertility issues, malignancy, and postfinasteride syndrome have been concerns of users and prescribers of the drug. Pre-existing mental health disorder may put patients at an increased risk of nocebo, while the prevalence of personality disorders in subjects with MPHL is known to be higher than in the general population, specifically histrionic personality disorder. We devised a system for patient selection and risk assessment, including fertility issues, regular PSA determinations, and specific mental health assessment. For those who choose regular prostate cancer screening, the use of finasteride meaningfully reduces the risk of prostate cancer. While gynecomastia is a known, rare adverse effect of finasteride, so far, studies support the view that exposure to finasteride is not associated with male breast cancer risk. Patient understanding and involvement are central to optimal treatment selection and active patient role in treatment.

Introduction: Alopecia areata (AA) is a chronic, autoimmune condition affecting hair follicles, and its occurrence in the paediatric population is associated with poorer prognosis and limited treatment options compared to adults. Treatment with oral methotrexate (MTX) has been documented in adults, but there is a paucity of data for its use in the paediatric population. We aimed to study the efficacy and tolerability of MTX in severe paediatric AA. Methods: We performed a retrospective review on paediatric patients with severe AA who were treated with MTX in our centre from January 2019 to December 2020. Results: Thirteen patients were included (6 boys and 7 girls) aged between 4 and 16 years at the initiation of MTX (mean age of 8.8 years). The interval from diagnosis of AA to commencement of MTX was between 8 months and 9 years (mean duration of 3.3 years). Oral MTX was administered once weekly with a mean maximal dose of 0.4 mg/kg/dose. Out of 12 assessable patients, 5 were considered treatment success as they had more than 50% regrowth, while the other 7 were treatment failures. No serious side effects were reported. Conclusion: MTX was shown to have variable efficacy for the treatment of paediatric AA with overall good tolerability. MTX can be considered in the treatment of severe refractory AA for children.

TAFRO syndrome is a relatively new disease entity first reported in 2010. We report a case of TAFRO syndrome accommodated by abnormal exacerbation of moderately differentiated gastric adenocarcinoma. The pathophysiology of TAFRO syndrome is largely unknown, but because the disease often responds to immunosuppressive therapy and also because T follicular helper (Tfh) cells are reported to be drastically decreased in TAFRO syndrome, involvement of a dysregulated immune system can be speculated. Growing evidence points toward a pivotal role of Tfh cells in tumor immunity through supporting ectopic lymphoid structures, which are recruitment sites for cells directly engaging in antitumor activity such as CD8+ T cells, NK cells, and macrophages. In fact, Tfh cells are reported to positively correlate with longer survival in human colorectal and breast cancer. Combined with our observations of hyperprogressive gastric cancer in the presented patient, an impaired tumor immunity is strongly indicated in TAFRO syndrome.
