Authors: Agnihotri Mona , Sathe Pragati , Singh Avanika , Kothari Kanchan , Asthana Ankita 
Published: June 2023

AbstractHepatocellular carcinoma (HCC) is associated with an aggressive behavior and a strong tendency for extrahepatic metastasis. Although 5%–15% patients have metastases at diagnosis, presentation with symptoms exclusively related to extrahepatic metastases is rare. An 82‐year‐old male presented with an isolated left anterolateral chest wall swelling. Ultrasonography revealed a soft tissue mass involving the anterior chest wall with adjacent rib erosion. Serum protein electrophoresis showed increase in beta‐2 region. A clinical diagnosis of multiple myeloma was considered. Fine needle aspiration cytology from the swelling showed loosely cohesive clusters of polygonal cells with traversing blood vessels. Cells showed abundant vacuolated to granular cytoplasm, round nuclei with frequent intranuclear cytoplasmic inclusions. A differential of metastatic HCC and renal cell carcinoma was considered. Subsequent imaging showed a 12 cm mass in the liver. Biopsy from chest wall mass with immunohistochemistry confirmed the diagnosis. Lungs and lymph nodes are the commonest sites for metastatic HCC; presentation as chest wall metastasis is rarely reported. The classical cytomorphology of HCC proved useful in diagnosing metastasis at a rare site. Recent studies have shown that beta‐2‐globulin is a promising biomarker for early diagnosis of HCC in patients with chronic liver disease.

AbstractDespite much progress achieved, corrosion in oil and gas pipelines remains a concern due to industrial failures, and environmental and economic damages. Oil and gas pipeline failures are very common as a result of the natural degradation of carbon steel exposed to the marine environment. It has been reported that the presence of microorganisms in seawater contributes to the intensification of corrosion and subsequent biofilm formation on metal surfaces. Few scientific publications have investigated the effects of seawater containing natural microorganisms on the internal corrosion of pipelines, which is the motivation for this study. The present study aims to report the corrosion behavior of carbon steel American Petroleum Institute (API) 5 L X65 exposed to seawater collected from the Persian Gulf containing microorganisms such as sulfate‐reducing bacteria (SRB), iron‐reducing bacteria (IRB), and acid‐producing bacteria (APB). Microorganisms were detected, segregated, colonized, and finally injected into autoclaved seawater to investigate their effect on the corrosion behavior of carbon steel. Nondestructive electrochemical techniques were performed to study the corrosion behavior and field emission electron microscope images and energy dispersive x‐ray analysis (EDS) were also utilized to characterize the corrosion products. The results confirmed the amounts of oxygen and iron presented of FeO as the main corrosion product in abiotic conditions. Corrosion products and electrochemical properties of steel have been influenced by microbial activity. The variation of the open circuit potentials (OCP) and Electrochemical Impedance Spectroscopy (EIS) demonstrated that SRB and APB could not only significantly harm an alloy, but also could alter its electrochemical behavior from uniform to local damage. The outcomes proved that biofilm formation and bacterial activity can cause serious degradation.

Published: June 2023

AbstractIn recent seismic analyses, it is considered that the structural damping ratio should be treated as independent of frequency, for safety side estimation. Therefore, frequency‐insensitive damping is required for realistic seismic simulations. This paper investigates the performance of various sparse matrix damping models (extended Raleigh, capped viscous and uniform damping) in the inelastic seismic analysis of a 35‐story moment‐frame steel building. These sparse matrix damping models were compared with Rayleigh, tangent Rayleigh, and Wilson‐Penzien (modal) damping models to provide insight into damping models suitable for large‐scale inelastic response history analysis (RHA). First, the necessity of frequency‐insensitive damping in large‐scale analysis is illustrated via numerical simulations. Then, the vibration characteristics with simultaneous inputs of horizontal and vertical ground motion are analyzed using the abovementioned damping schemes, and their results are compared. The comparisons are analyzed by focusing on horizontal displacement/acceleration, story drift angle, beam‐end ductility factor, the amplitude due to beam vibration, and the associated vertical acceleration. Finally, the computation speeds are compared. As a result, it is shown that although these sparse matrix damping models are practically useful, they are not yet sufficient and present challenges.
MS‐ADS: Multistage Spectrogram image‐based Anomaly Detection System for IoT security

Published: June 2023

AbstractThe innovative computing idea of Internet‐of‐Things (IoT) architecture has gained tremendous popularity over the last decade, resulting in an exponential increase in the connected devices and the data processed in the IoT networks. Since IoT devices collect a massive amount of sensitive information exchanged over the traditional internet, security has become a prime concern due to the more frequent generation of network anomalies. A network‐based anomaly detection system can provide the much‐needed efficient security solution to the IoT network by detecting anomalies at the network entry points through constant traffic monitoring. Despite enormous efforts by researchers, these detection systems still suffer from lower detection accuracy in detecting anomalies and generate a high false alarm rate and false‐negative rate in classifying network traffic. To this end, this paper proposes an efficient Multistage Spectrogram image‐based network Anomaly Detection System (MS‐ADS) using a deep convolution neural network that utilizes a short‐time Fourier Transform to transform flow features into spectrogram images. The results demonstrate that the proposed method achieves high detection accuracy of 99.98% with a reduction in the false alarm rate to 0.006% in classifying network traffic. Also, the proposed scheme improves predicting the anomaly instances by 0.75% to 4.82%, comparing the benchmark methodologies to exhibit its efficiency for the IoT network. To minimize the computational and training cost for the model re‐training phase, the proposed solution demonstrates that only 40500 network flows from the dataset suffice to achieve a detection accuracy of 99.5%.
Do maternal power assertive discipline and warmth interact to influence toddlers' emotional reactivity and noncompliance?
Authors: Engel Kivilcim D. , Lunkenheimer Erika , Corapci Feyza 
Published: June 2023

AbstractEmotional and behavioural self‐regulation emerges during infancy and toddlerhood and is heavily influenced by parenting. Parents facilitate toddlers' behavioural regulation (e.g., compliance) by using appropriate control with warmth and managing children's emotional reactivity during situational demands. In contrast, power assertive discipline may strain children's regulatory skills, for example by evoking toddlers' negative affect. However, we have more to learn about how discipline relates to toddlers' self‐regulation in the moment and whether concurrent displays of parental warmth may moderate these relations. Mother–toddler dyads (N = 74, Mage = 13.30 months) from low‐to‐middle income Turkish families participated in a 3‐min laboratory task, in which toddlers needed to delay playing with an attractive toy. Maternal discipline, warmth, toddler's emotional reactivity, and noncompliance were coded from observations. Results showed that higher power assertive discipline was associated with more frequent emotional reactivity in toddlers whose mothers' showed warmth during the <84% of the task duration. Maternal warmth was negatively associated with child noncompliance, but warmth did not interact with power assertive discipline in relation to noncompliance. Results suggest that observed power assertive discipline is meaningfully related to toddlers' emotional reactivity and higher levels of expressed maternal warmth attenuates these relations.
Star power as quality signal or marketing effect? A path analysis on China's motion‐picture industry
Authors: Kang Lili , Peng Fei 
Published: June 2023

AbstractThis study investigates the relationship between star power, artistic excellence, and the commercial success of Chinese movies from 2009 to 2018 based on a two‐path structural model. Artistic excellence was measured based on industry recognition; more specifically, the winners of seven major movie awards in the greater China region, which reflect the critical and popular evaluations of reviewers and consumers. The commercial success was measured by box office performance and the level of buzz among the audience. While the paths of artistic excellence and commercial movie success are essentially separable, as well as conceptually and empirically distinct, movie star power may influence both. Our findings indicate that star power had negative signal effects on critical and popular evaluation as well as industry recognition, but positive marketing effects on critical and popular buzz as well as box office performance. Indeed, star power has indirect positive effects that can outweigh its negative effects. Thus, star power is the key to success in these two seemingly unrelated paths in China. Moreover, these findings have several implications for international investors, producers, actors, and directors who are participating in the Chinese motion picture industry.

Published: June 2023

AbstractThe development of infant mental health (IMH) services globally is still in its early stages. This qualitative study aims to understand the challenges of setting up IMH services and explores the views and experiences of 14 multi‐disciplinary stakeholders who are part of the IMH implementation group in a large Scottish health board. Six major themes were identified through thematic analysis. This paper examines the most prominent theme “Systems” alongside the theme “Gaps in Current Service”. The theoretical framework of “candidacy” is found to be a valuable way to conceptualize the complex systemic layers of micro, meso, and macro factors that contribute to the challenges of setting up services. At the micro level, key themes included the view that services must be accessible, individualized, and involve families. At the meso level, in line with the aims of the service, multiagency integration, aspects of early intervention, and clear operating conditions were all seen as important. Finally, at the macro level, perhaps the biggest challenge perceived by stakeholders is delivering a service that is entirely infant‐focused. These findings will help inform policy makers about factors considered by professionals to be vital in the establishment of IMH services in Scotland and across the globe.

AbstractIntroductionWhile a large proportion of people with HIV (PWH) have experienced SARS‐CoV‐2 infections, there is uncertainty about the role of HIV disease severity on COVID‐19 outcomes, especially in lower‐income settings. We studied the association of mortality with characteristics of HIV severity and management, and vaccination, among adult PWH.MethodsWe analysed observational cohort data on all PWH aged ≥15 years experiencing a diagnosed SARS‐CoV‐2 infection (until March 2022), who accessed public sector healthcare in the Western Cape province of South Africa. Logistic regression was used to study the association of mortality with evidence of antiretroviral therapy (ART) collection, time since first HIV evidence, CD4 cell count, viral load (among those with evidence of ART collection) and COVID‐19 vaccination, adjusting for demographic characteristics, comorbidities, admission pressure, location and time period.ResultsMortality occurred in 5.7% (95% CI: 5.3,6.0) of 17,831 first‐diagnosed infections. Higher mortality was associated with lower recent CD4, no evidence of ART collection, high or unknown recent viral load and recent first HIV evidence, differentially by age. Vaccination was protective. The burden of comorbidities was high, and tuberculosis (especially more recent episodes of tuberculosis), chronic kidney disease, diabetes and hypertension were associated with higher mortality, more strongly in younger adults.ConclusionsMortality was strongly associated with suboptimal HIV control, and the prevalence of these risk factors increased in later COVID‐19 waves. It remains a public health priority to ensure PWH are on suppressive ART and vaccinated, and manage any disruptions in care that occurred during the pandemic. The diagnosis and management of comorbidities, including for tuberculosis, should be optimized.
Resilience and well‐being among expatriate entrepreneurs: Envisioning life after a global crisis
Authors: Abonil Mariam , Shrivastava Anita , Hyland Lynda 
Published: June 2023

AbstractExpatriate entrepreneurs are exposed to greater risk than ‘local’ entrepreneurs, particularly during exogenous crises. Their psychological characteristics can influence how they view such threats and may inform resultant coping strategies. Reflecting on pre‐entrepreneurship experiences and envisioning life post‐crisis allows identification of 'what worked' for entrepreneurs throughout their career journeys. This exploratory study investigated the career reflections and future planning of 12 purposively sampled for‐profit expatriate entrepreneurs based in the United Arab Emirates, a country with a primarily expatriate workforce. Reflexive Thematic Analysis of semi‐structured interview data revealed two overarching themes, “resilience” and “valuing relationships.” These were evident in participants’ career development narratives, demonstrating the centrality of these positive psychology constructs throughout their career journeys in impacting business outcomes and well‐being. Despite facing significant challenges, participants were hopeful due to intrinsic (resilience) and extrinsic (relationship) factors, both of which may support psychological health and aid future career efforts. These findings are relevant to career counselors and entrepreneurship educators, who can promote the role of soft skills, including relationship‐building, and positive psychological constructs as buffers against future challenges.

Published: June 2023

AbstractBackgroundAflatoxin B1 (AFB1) has been considered as a prevailing natural carcinogenic mycotoxin in various food and feedstuff products, posing serious endangers to human health. The quantitative and selective detection of AFB1 was significantly essential for food safety control.ResultsWe developed a label‐free fluorescent aptasensor using a target‐binding aptamer probe as the rolling circle amplification (RCA) primer for AFB1 detection. In the presence of AFB1, the probe preferentially combined with AFB1 rather than binding to the circular template, inhibiting the initiation of RCA process. The detection limit of the proposed method was as low as 6.6 nM, and the linear dynamic response range was four orders of magnitude wide. Besides, it revealed excellent specificity for AFB1 and high‐quality detection performance in food samples.ConclusionThe presented detection method was simple, rapid, and economical, which indicated a promising application in food safety monitoring.

AbstractThe symptom structure of ICD‐11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) and the validity of the International Trauma Questionnaire (ITQ) are yet to be tested among civilians in an active war zone. The present investigation examined the factor structure of the ITQ, the internal consistency of observed scores, and their associations with demographic characteristics and war‐related experiences using a nationwide sample of 2,004 adults from the general population of Ukraine approximately 6 months after the full‐scale Russian invasion in 2022. Overall, rates of endorsement across all symptom clusters were high. The mean total number of war‐related stressors reported was 9.07 (SD = 4.35, range: 1–26). Internal reliability was good for all six ITQ subscales, Cronbach's αs = .73–.88, and the correlated six‐factor model was found to provide the best representation of the latent structure of the ITQ in the present sample based on fit indices. There was evidence of a dose–response relationship, with increasing scores on all symptom clusters associated with higher total reported war‐related stressors.

Published: June 2023

AbstractObjectivesTo examine the relationship between neighborhood‐level advantage and severe obstructive sleep apnea (OSA) in children.MethodsA retrospective case–control study was conducted on 249 children who underwent adenotonsillectomy and had full‐night polysomnography conducted within 6 months prior. Patients were divided into more or less socioeconomically disadvantaged groups using a validated measure, the area deprivation index (ADI). The primary outcomes were the relationship between the apnea–hypopnea index (AHI) and the presence of severe OSA, and the secondary outcome was residual moderate or greater OSA after tonsillectomy.ResultsOf the 249 children included in the study, 175 (70.3%) were socially disadvantaged (ADI > 50). The median (interquartile range [IQR]) age was 9.4 (7.3–12.3) years, 129 (51.8%) were male, and the majority were White (151, 60.9%), Black (51, 20.6%), and/or of Hispanic (155, 62.5%) ethnicity. A total of 140 (56.2%) children were obese. The median (IQR) AHI was 8.9 (3.9–20.2). There was no significant difference in the median AHI or the presence of severe OSA between the more and less disadvantaged groups. Severe OSA was found to be associated with obesity (odds ratio [OR] = 3.13, 95% confidence interval [CI] = 1.83–5.34), and residual moderate or greater OSA was associated with older age (OR = 1.20, 95% CI = 1.05–1.38).ConclusionsThe ADI was not significantly associated with severe OSA or residual OSA in this cohort of children. Although more neighborhood‐level disadvantage may increase the risk of comorbidities associated with OSA, it was not an independent risk factor in this study.Level of EvidenceLevel 4.

Published: June 2023

AbstractIntroductionPerinatal mental health (PMH) conditions affect around one in four women, and may be even higher in women from some ethnic minority groups and those living in low socioeconomic circumstances. Poor PMH causes significant distress and can have lifelong adverse impacts for some children. In England, current prevalence rates are estimated using mental health data of the general population and do not take sociodemographic variance of geographical areas into account. Services cannot plan their capacity and ensure appropriate and timely support using these estimates. Our aim was to see if PMH prevalence rates could be identified using existing publicly available sources of routine health data.MethodsA review of data sources was completed by searching NHS Digital (now NHS England), Public Health England and other national PMH resources, performing keyword searches online, and research team knowledge of the field. The sources were screened for routine data that could be used to produce prevalence of PMH conditions by sociodemographic variation. Included sources were reviewed for their utility in accessibility, data relevance and technical specification relating to PMH and sociodemographic data items.ResultsWe found a PMH data ‘blind spot’ with significant inadequacies in the utility of all identified data sources, making it impossible to provide information on the prevalence of PMH in England and understand variation by sociodemographic differences.ConclusionsTo enhance the utility of publicly available routine data to provide PMH prevalence rates requires improved mandatory PMH data capture in universal services, available publicly via one platform and including assessment outcomes and sociodemographic data.
Brauer groups and étale homotopy type
Authors: Moutand Mohammed 
Published: June 2023

AbstractExtending a result of Schröer on a Grothendieck question in the context of complex analytic spaces, we prove that the surjectivity of the Brauer map for schemes depends on their étale homotopy type. We use properties of algebraic spaces to apply this to some classes of proper and smooth algebraic schemes. In particular, we recover a result of Hoobler and Berkovich for abelian varieties.
Coordination Stoichiometry Effects on the Binding Hierarchy of Histamine and Imidazole–M2+Complexes
Authors: Song Jake , Khare Eesha , Rao Li , Buehler Markus J , Holten‐Andersen Niels 
Published: June 2023

AbstractHistidine–M2+coordination bonds are a recognized bond motif in biogenic materials with high hardness and extensibility, which has led to growing interest in their use in soft materials for mechanical function. However, the effect of different metal ions on the stability of the coordination complex remains poorly understood, complicating their implementation in metal‐coordinated polymer materials. Herein, rheology experiments and density functional theory calculations are used to characterize the stability of coordination complexes and establish the binding hierarchy of histamine and imidazole with Ni2+, Cu2+, and Zn2+. It is found that the binding hierarchy is driven by the specific affinity of the metal ions to different coordination states, which can be macroscopically tuned by changing the metal‐to‐ligand stoichiometry of the metal‐coordinated network. These findings facilitate the rational selection of metal ions for optimizing the mechanical properties of metal‐coordinated materials.
