Background. Osteoarthritis (OA) is the most common disease of the hip in adults, and its etiology is divided into two groups: primary and secondary. Although acetabular dysplasia is the most frequent reason for total hip arthroplasty (THA) in Japan, primary OA has increased recently. Although there are two types of femoral head migration in primary OA: superior and medial, there are some patients with prominent femoral head lateralization. This study aimed at evaluating the relationship between femoral head lateralization and bone morphology of the acetabulum and proximal femur using radiographic factors in primary OA of the hip. Methods. A retrospective study was conducted between 2008 and 2017 to assess 1308 hips with OA who underwent primary THAs at our institute. The diagnostic criteria for primary OA were Crowe type 1, Sharp’s angle <45°, and center-edge (CE) angle >25°. We classified patients with primary OA into two groups based on femoral head lateralization: group L with lateralization or group N without. Radiographic factors included Sharp’s angle, CE angle, acetabular inclination, acetabular depth ratio (ADR), acetabular head index (AHI), and femoral neck-shaft angle (FNA), all examined on an anteroposterior pelvic radiograph. Femoral neck anteversion was calculated using computerized axial tomography. Results. Primary OA was diagnosed in 210/1308 hips (16.1%) (group L: 112 hips (8.6%); group N: 98 (7.5%)). Patient demographics were not significantly different. Radiographic factors with observed significant differences between group L and group N were the average CE angle (33.0° vs. 35.1°, respectively,

p

 = 0.009), ADR (251.6 vs. 273.4,

p

 < 0.001), AHI (77.2 vs. 80.4,

p

 < 0.001), and FNA (136.9° vs. 134.8°,

p

 = 0.012). Conclusions. This investigation suggests that primary OA with femoral head lateralization demonstrated specific identifiable radiographic characteristics in the acetabulum and proximal femur that might contribute to hip joint instability such as the dysplastic hip.

Published: August 2023

In this work, the average effects of the Lorentz acceleration on the charged spacecraft’s orbit are studied encounter with relativistic correction. The relativistic correction as function of the orbital elements, and may be time, is formulated. Lagrange planetary equations are used to calculate the perturbations due to considered perturbing forces. The needed conditions to neutralize the effects of the relativistic corrections, using Lorentz acceleration, are derived. Numerical examples for different kinds of orbits are applied.

Authors: Jamali Ayaan M. , Kethamreddy Manasa , Burkett Brian J. , Port John D. , Pandey Mukesh K.
Published: August 2023

Amyotrophic lateral sclerosis (ALS) is a disease leading to progressive motor degeneration and ultimately death. It is a complex disease that can take a significantly long time to be diagnosed, as other similar pathological conditions must be ruled out for a definite diagnosis of ALS. Noninvasive imaging of ALS has shed light on disease pathology and altered biochemistry in the ALS brain. Other than magnetic resonance imaging (MRI), two types of functional imaging, positron emission tomography (PET) and single photon emission computed tomography (SPECT), have provided valuable data about what happens in the brain of ALS patients compared to healthy controls. PET imaging has revealed a specific pattern of brain metabolism through [18F]FDG, while other radiotracers have uncovered neuroinflammation, changes in neuronal density, and protein aggregation. SPECT imaging has shown a general decrease in regional cerebral blood flow (rCBF) in ALS patients. This educational review summarizes the current state of ALS imaging with various PET and SPECT radiopharmaceuticals to better understand the pathophysiology of ALS.
Refined Division Features Based on Transformer for Semantic Image Segmentation
Authors: Li Tianping , Wei Yanjun , Liu Meilin , Yang Xiaolong , Zhang Zhenyi , Du Jun
Published: August 2023

Transformer can build global relationships between pixels and enhance pixel representation. The existing methods only establish the context relationship from the whole image but will reduce the representation between the category areas. In addition, the existing methods based on the transformer self‐attention do not combine the advantages of convolution and transformer, resulting in more calculation parameters of the model. In order to solve these two problems, this paper proposes to enhance the segmentation accuracy and performance by enhancing the relationship between image‐level regions and the relationship between semantic level pixels. First, we design a refined division feature (RDF) module to enhance the channel representation and thus the same locale representation. Second, we design a transformer based on convolution (CTrans), which first computes the relationship between similar pixels and enhances the pixel representation. Then, the feature map is compressed and enriched to reduce the computational load of CTrans, and finally the relationship between pixels is established from a global perspective. We design a refined division feature module based on transformer for semantic image segmentation (RFT) model combining RDF and CTrans module. The experimental results show that the mIoU result of our method in Cityscapes test data set is 81.9%, and the model parameter is 64.6M, which is superior to other methods in terms of data. In addition, we conducted visualization experiments with Cityscapes and Pascal voc 2012 datasets with other methods, and the results showed that our method was superior to other methods.

Published: August 2023

The study is aimed at assessing the impacts of postharvest handling practices on the quality and safety of tuna sold at the Honiara Fish Market (HFM), Solomon Islands. Two major approaches were adopted: (1) face-to-face interviews of 60 participants using questionnaires and physical observations of the supply chains and postharvest handling practices and (2) determination of time-temperature, quality index, histamine, and microbial load of tuna and contact surfaces. Sampling was conducted on both the wet season (WS) and dry season (DS), of which 36 samples from both batches of fresh tuna (FT) and brined tuna (BT) were analyzed. Three critical control points (CCPs) were identified in the supply chains of both FT and BT, where samples were obtained for scientific analyses. The average body temperature for WS tuna exposed for 9-10 h with low or no ice after catch was 3°C for FT and 15°C for BT, while DS samples were 26°C and 31°C for FT and BT, respectively. The quality index (QI) for WS showed a significant difference (

P
<
0.05

) at 0 for FT and 8 for BT, while both DS showed a significant increase at 16 for BT and 5 for FT. Histamine levels for all the samples increased across the three CCPs, however with levels <50 mg/L, while microbial load for both seasons and for both samples were within the required specifications. However, contact surfaces for both seasons revealed high levels of microbial contamination. This study reveals that poor handling practices along the tuna supply chains of fish sold at the HFM were observed; however, all the tuna was safe for consumption when cooked properly.

Published: August 2023

High renewable energy penetration worsens systems instability. Balancing consumption energy and generation output energy reduces this instability. This paper introduces coordination control to coordinate the flow of electricity between MG buses and to stabilize the system under variable load, generation conditions. The adopted MG regulates the bidirectional DC/AC main converter using digital proportional resonant controllers in a synchronous reference frame. A maximum power point tracker-based boost DC/DC converter enables the wind turbine and solar photovoltaic to harvest maximum power. Traditional methods such as perturb and observe and incremental conductance maximum power trackers cannot solve nonlinearity and inaccurate responses. This work provides a hybrid maximum power tracker strategy to modify the responses of standard maximum power point techniques based on particle swarm optimization-trained adaptive neuro-fuzzy inference system (ANFIS-PSO) to achieve quick and maximum solar power with minimal oscillation tracking. Concerning the management system, this paper adopts a recent meta-heuristic algorithms-based DSM program to modify consumers’ electricity use by shifting the load appliances to off-peak demand periods. The adopted algorithms for DSM are sparrow search algorithm (SSA), binary orientation search algorithm (BSOA), and cockroach algorithm (CA). Finally, based on energy Internet technology, ThingSpeak cloud-based MATLAB is adopted to gather and display real-time data streams and generate graphical analyses. The simulation results reveal that the recommended coordinating control produces quick grid frequency responsiveness and zero steady-state errors. The optimal demand management program minimizes peak energy consumption from 5.2 kWh to 4.6 kWh. All DSM methods cost 439.1 $ per month, compared to 484.4 $ for the nonscheduling load profile.

The study of the existence and uniqueness of solutions to 2D systems utilizing the generalized proportional fractional derivative operator is the focus of this work. We also derive a finite difference scheme in order to numerically approximate such an operator, and we prove that the method we propose is convergent. Several tests are performed at the end to illustrate the robustness of our algorithm.

Published: August 2023

Conduction restoration in second- and third-degree atrioventricular (AV) block after revascularization in acute coronary syndrome (ACS) setting is well established, however this is not the case in non-ACS setting. We present a case of a patient referred for permanent pacemaker implantation, due to high degree AV block (HAVB), who restored his conduction possibly due to targeted revascularization. Thus, this case sheds insight in the reversibility potential of HAVB after revascularization in non-ACS patients, which although signified in current literature, is still far from being a recommendation, due to lack of robust scientific confirmation.

Introduction. The aim of this study was to evaluate the practicality of the signal transducer and activator of transcription (STAT) 3 polymorphisms as a predictive biomarker and sorafenib trough concentration as a monitoring biomarker for hand-foot skin reaction (HFSR) in patients with hepatocellular carcinoma (HCC). Methods. In total, 43 Japanese HCC patients were included. Sorafenib concentrations were measured, if possible, on days 8, 29, 35, and 57. The sorafenib concentration on day 8 (Cday8) was used for the analysis of HFSR occurring up to day 29. The median concentration for each patient (Cmedian) was used for HFSR occurring up to day 57 (study period). The STAT3 single nucleotide polymorphism (SNP) rs4796793 was determined using cell-free DNA extracted from plasma. Result. The Cday8 tended to be higher in the HFSR onset or grade ≥ 2 HFSR severity group than in the non-HFSR or grade ≤ 1 HFSR severity group. The Cmedian was significantly higher in the HFSR onset or grade ≥ 2 group than in the non-HFSR or grade ≤ 1 HFSR group. The Cmedian thresholds for predicting HFSR onset and severity were 3.62 μg/mL and 6.10 μg/mL, respectively. There was no association between STAT3 rs4796793 and HFSR onset or severity. In multivariate analysis, Cmedian values ≥ 3.62 μg/mL and >6.10 μg/mL were associated with the increased risk of HFSR onset (odds ratio: 16.6,

p

 < 0.01) and severity (odds ratio: 15.7,

p

 < 0.01), respectively. Conclusion. Monitoring of the sorafenib trough concentration may be practical for avoiding HFSR.

Background and Aim.Ghana is one of the many Sub‐Saharan African countries battling malaria. The disease is treated with orthodox medication as well as some home‐grown remedies, mainly from plants. This study sought to identify these local remedies being marketed, focusing on the active ingredients being used. Methods. Pharmacy shops were randomly scouted and products were observed. The active ingredients were documented and their frequencies were determined. Results.Forty‐four (44) plant species belonging to twenty‐eight (28) families were recorded for the treatment of malaria in the survey. The predominant families were the Leguminosae and Meliaceae families. Cryptolepis sanguinolenta (Ghanaian quinine or yellow dye root) and Azadirachta indica (neem tree) were the most cited plants. Cryptolepis and neem tree were used 17 and 15 times, respectively, in the finished herbal products for treating malaria. Conclusion. Cryptolepis sanguinolenta and Azadirachta indica (neem tree) are important herbs for the treatment of malaria in Ghana. Locally manufactured herbal antimalarials are important for the treatment of malaria in urban and rural communities in Ghana.
Irreversible Demagnetization of a Large Capacity Line-Start Permanent Magnet Synchronous Motors considering Influence of Permanent Magnet Temperature

Published: August 2023

This paper investigates the irreversible demagnetization (ID) of a large capacity line-start permanent magnet synchronous motor (LSPMSM) considering influence of permanent magnets’ (PMs) temperature. The phenomenon of ID occurs on the pull-in stage and close to the cusp of magnet on the direct-axis direction. The PMs’ temperature causes the demagnetization curve to move down and the knee point to shift up. The extensive area ID of magnet will lead to pulling in synchronism failure and operation at the asynchronous state. A prototype is fabricated to validate the analysis that temperature of PMs will bring more serious ID risk and degradation of motor performance.
Risk Assessment Method and Application of Urban River Ecological Governance Project Based on Cloud Model Improvement
Authors: Xu JunKe , Zhang Xia
Published: August 2023

This study classifies risk factors and establishes the risk-evaluation index system for an urban river ecological management project. That system includes construction personnel risk, construction technology risk, construction management factor risk, construction duration factor risk, and other risks. A total of 23 indicators determine the level and standard of each indicator. This study proposes a risk index system that uses the cloud model evaluation method and explains that model’s process. To demonstrate the risk evaluation methodology, it was applied to the ecological management project of Jinghe River in Jinghe New City, China. The results showed that: (1) the urban river ecological management project was subject to “a medium level of personnel risk, management risk, and construction period risk and a relatively high level of technical risk and other risks.” According to the evaluation results, the overall risk level of the project was medium, which is consistent with the risk level of the Jinghe River ecological management project at the current stage. (2) The limitation of the subjective qualitative concept caused by the traditional fuzzy comprehensive evaluation was fully considered in the improved method, and the application of the cloud-model based improved method in risk evaluation of the urban river ecological management project significantly improved the reliability and visualization of the evaluation results. Finally, the urban river ecological management project in China was adopted as an example to prove that the model boasts high stability, and some corresponding countermeasures were also proposed. The research results are expected to provide valuable references and scientific criteria for implementing urban river ecological management projects.

Deaf and dumb people struggle with communicating on a day-to-day basis. Current advancements in artificial intelligence (AI) have allowed this communication barrier to be removed. A letter recognition system for Arabic sign language (ArSL) has been developed as a result of this effort. The deep convolutional neural network (CNN) structure is used by the ArSL recognition system in order to process depth data and to improve the ability for hearing-impaired to communicate with others. In the proposed model, letters of the hand-sign alphabet and the Arabic alphabet would be recognized and identified automatically based on user input. The proposed model should be able to identify ArSL with a rate of accuracy of 97.1%. In order to test our approach, we carried out a comparative study and discovered that it is able to differentiate between static indications with a higher level of accuracy than prior studies had achieved using the same dataset.
Pentecostals and Premillennialist Dispensationalism
Authors: Nel Marius
Published: August 2023

Early Pentecostals believed their experience of Spirit baptism represented the latter rain of prophecy that introduced Christ’s return. Therefore, their goal was to preach the Pentecostal gospel to all, expecting their success to hasten Christ’s return. They read the Bible through the lens of their charismatic experiences and left room for the Spirit, who inspired the Scriptures to explain its meaning. The next generations adopted a fundamentalist hermeneutical angle and included premillennialist dispensationalism to understand biblical prophecies. The doctrines of rapture, premillennialism, and a distinction between Israel and the church imply that the church belongs to the ‘parenthetical age’, indicating a delay in the prophetic timeline when Jews rejected Jesus. It took the emphasis away from the urgent need to evangelise the world, focusing on explaining the biblical ‘last events’ and setting timetables. It is argued that Pentecostals’ dispensationalism betrayed their unique ethos, values, and hermeneutical angle.
Advanced imaging and quantification of the cambium and developing xylem in eucalypts using X-ray micro- and nano-computed tomography
Authors: Schoeman Letitia , Drew David M.
Published: August 2023

In recent years, the popularity of X-ray computed tomography (CT), as a non-destructive imaging technique, has continued to expand in various research domains. In wood research, X-ray CT has proven to be useful for three-dimensional (3D) structural studies investigating the complex tissues of trees. Wood formation (i.e., xylogenesis) initiates in the cambium and a narrow zone of subsequent differentiation, both of which play key roles in plant growth and development. However, the dynamics of xylogenesis in eucalypts remain relatively poorly understood, in large part due to challenges in sampling, imaging, and characterizing the cambium. Therefore, the aim of this study was to present a workflow to evaluate the feasibility of using X-ray CT to characterize and quantify the structural properties of the cambium in eucalypts. The growth responses of Corymbia hybrid seedlings, exposed to either irrigated or droughted conditions, was investigated by monitoring the structural development of the cambium. To track microstructural changes in the cambium, the same seedlings were imaged with X-ray micro-CT (μCT) one day before the treatments and again six days after the respective treatments. After the last X-ray μCT scan, X-ray nano-CT was also applied. Using image analysis techniques, the morphological characteristics of the cambium could be determined. X-ray μCT displayed a larger, thicker cambial zone in irrigated plants, while a much thinner cambium was visible in droughted seedlings. X-ray nano-CT revealed that droughted plants were associated with a significantly () smaller cambium volume containing smaller cells, compared to the cambium of irrigated plants. Light microscopy was used to validate the CT results and demonstrated no significant () difference in the cambium width and cell diameter obtained from the two respective CT techniques. The findings of this study proved X-ray CT to be a valuable tool for examining the effect of changing environmental conditions on the complex cambium structure of Corymbia hybrid seedlings.
Words of Wonder: The Cognitive and Semantic Dimension of the Literal and Figurative Denominators for wonder in Old English Sources
Authors: Minaya Gómez Francisco Javier
Published: August 2023

Based on the most recent research on emotion and, specifically, on contemporary aesthetic emotion theories, and combining methods from cognitive and historical linguistics, this paper aims at looking into the cognitive and semantic dimension of Old English literal and figurative denominators of wonder. Exploring how these terms are used in the Old English corpus, this paper highlights a recurrent use of literal emotion terms for wonder with varying semantics, and a wide array of figurative expressions that rely on the most common action tendencies and somatic profiles that are attributed to this emotion. This research stresses the rich variety that Old English authors had at their disposal when describing wonder-experiences and the many ways in which these authors described and narrated these emotional experiences, all of which, in extreme, reveals important information about the semantic dimension of these terms and identifiable patterns of conceptualisation for this emotion.
Banquo’s Daughters and the Lost #MeToo Macbeth, and Early Modern Alt-Media
Authors: Borlik Todd Andrew
Published: August 2023

This article investigates the disturbing accusation, first recorded in 1652, that Macbeth abducted and possibly raped a daughter of Banquo’s. Since Banquo himself was apparently fabricated by the Aberdonian chronicler Hector Boece in the 1520s to romanticize the Stuart dynasty’s origins, his daughter has no historical basis and tales of her grim fate likely represent a literary embellishment on the scene in which Malcolm reports Macbeth had confessed that kingship would awaken his insatiably lustful nature. These rumours, circulating at least by the early 1650s, would eventually culminate in an obscene prose romance entitled The Secret History of Mack-beth, first printed in 1708 shortly after the Acts of Union. Although the article entertains the tantalizing possibilities that Banquo’s daughter may have featured in the legendary uncut Macbeth, in deleted or censored additions to the play by Thomas Middleton (who created several female characters with the same name as Banquo’s daughter), or an unrealized adaptation planned by John Milton, the evidence proves too circumstantial. A safer assumption would be that the underground Macbeth was spawned by the radical press following Charles II’s coronation as King of Scotland at Scone in 1651. Nevertheless, this apocryphal legend illuminates some gaps in Shakespeare’s tragedy and affords an early example of how Shakespearean drama might be appropriated by an early modern forerunner of alt-media to feed a twisted sexual politics.
Edmund Spenser’s Sense of an Ending
Authors: Russell Jesse
Published: August 2023

Throughout his Faerie Queene, Edmund Spenser depicts himself as a “poet magus” who can peer behind the veil of Nature in order to discover a “secret teaching” of ethical and political virtue that he will impart to his readers. His readers are thus tasked with the chore of reforming the fallen world through the creation of an empire under Elizabeth. However, in “The Two Cantos of Mutabilitie,” Spenser seems to relinquish this vision. Indeed, Mutabilitie, on one level serves as a mirroring figure of Spenser’s own ambitions. Mutabilitie’s claims for the fragility and mutability of (temporal) existence are prefigured throughout The Faerie Queene, but in “The Two Cantos,” they take center stage. Spenser’s depiction of Nature’s triumph over Mutabilitie provides a lesson for Spenser himself, and he appears to reject his bombastic claims of knowledge as well as his projected imperial vision for a position of humble supplication before God, whose Providence is the ultimately the most powerful force in The Faerie Queene.
The Virus as Remedy: COVID-19 and the End of the Populist Meta-Crisis
Authors: Bitschnau Marco
Published: August 2023

Understood not only as a challenge to democracy but as a crisis, populism has received widespread attention in both media and academic circles for the better part of the past decade. Yet the outbreak of COVID-19 and its escalation into a pandemic eclipsed the fear of rising populism within weeks: With lockdowns imposed and civil liberties suspended, it lost its menacing character and became a mere background nuisance. This, I argue in this article, is the consequence of a discursive constellation in which there is only room for one dominant crisis – a meta-crisis as I call it – at a time. Populism filled this meta-crisis role for a long while, but the COVID-19 shock redirected society’s attention to a more pervasive and immediate threat. While this does not spell the end of populism, it still marks a notable shift in the relative importance we attribute to it.
The Dynamics of Egyptian Politics
Authors: El-Ghobashy Mona
Published: August 2023

The political science scholarly consensus has long held up Egypt as a paradigm case of “authoritarian resilience.” Analysts emphasized the Mubarak regime’s shrewd manipulation of elections, strangling of NGOs, and instrumentalization of protest to shore up its power. This narrative was momentarily disrupted during Egypt’s 2011 to 2013 revolutionary situation, but reappeared unchanged after the July 2013 military coup. A Dynamics of Contention ( DoC) perspective sees the political world through different lenses. Where “authoritarian resilience” sees stability, DoC sees dynamism. “Authoritarian resilience” and similar social science models start with pre-constituted political actors, whereas DoC investigates how new political actors emerge and interact during episodes of contention. This article identifies three sites of contention that developed over the 30-year span of the Mubarak regime—elections; street protests, and legal mobilization—sketching how changing dynamics within these sites help us make sense of Egyptian politics before and after 2011.

Published: August 2023

Coronavirus disease 2019 (COVID-19) is associated with an increase in venous thrombotic and cardiovascular (CV) events has been reported during hospitalization. No systematic ultrasound follow-up to evaluate sequelae was ever that took place carried out prospectively associated with the evaluation of CV morbidity-mortality at 3 months post-discharge. Consecutive patients hospitalized for COVID-19 in the Amiens-Picardie University Hospital between 1st February and 31st August 2020 were included. The primary objective was the thrombosis incidence at 3 months after hospital discharge. Thrombosis was defined as either venous thromboembolism (VTE) or a CV event (CVE: myocardial infarction (MI), stroke or peripheral arterial disease). A secondary objective was to determine the risk factors for thrombotic events. We included 498 patients (279 men; 56%) of median age 66 (55-76) years. The primary composite outcome occurred in 27 patients (5.4%); 19 patients (3.8%) presented a CVE (stroke, n = 5; MI, n = 9; and peripheral arterial disease, n = 5). Two patients (0.8%) presented VTE. Six patients (1.2%) died. In multivariate analysis, a previous CVE was associated with thrombosis (OR 3.11; 95% CI 1.17-8.24). COVID-19 was significantly associated with thrombotic events post hospital discharge. Special attention should be given to CVE in the follow-up of patients with a previous thrombotic event.
Green colonialism and decolonial feminism: A study of Wayúu women’s resistance in La Guajira
Authors: Ramirez Jacobo , Vélez-Zapata Claudia Patricia , Maher Rajiv
Published: August 2023

This qualitative study scrutinises how green energy investment affects Indigenous Wayúu people in Colombia’s La Guajira region. Employing coloniality of power and decolonial feminism frameworks, we delve into Wayúu women’s struggles and resilience in defending territories against large-scale wind energy projects. Our findings suggest that governments and businesses are ‘tuned in’ to the economic benefits of these projects, yet ‘tuned out’ from Indigenous peoples’ ontologies, concerns, needs and cosmovisions. This dynamic prompts questions about the unintended consequences of organisations’ engagement with Indigenous peoples through corporate social responsibility (CSR) strategies. Despite good intentions, CSR practices that are ‘tuned out’ from Indigenous peoples’ cosmovisions may inadvertently reinforce power imbalances and further marginalise Indigenous communities. Our study highlights the need to honour Indigenous territories and protect Indigenous women’s rights in long-term investments. Clean energy focus can mask green colonialism, which Wayúu women actively safeguard, upholding Indigenous worldviews via feminist decoloniality. We advocate for businesses to incorporate diverse perspectives beyond the dominant western worldview into their climate change mitigation actions and CSR strategies, and for public policies to balance decarbonisation efforts with Indigenous rights to contribute to sustainable and equitable energy transitions.
Research on active disturbance rejection control strategy of electric power steering system under extreme working conditions
Authors: Zheng Zhu’An , Wei JinCheng
Published: August 2023

In response to the influence of motor interference, damping, friction, and other uncertain factors on the operation of electric power steering systems under extreme working conditions, this study proposes a control strategy for electric power steering systems based on an active disturbance rejection algorithm. In ADRC, the fastest tracking differentiator is used to arrange the transition process for the target signal, and the extended state observer compensates for the total disturbance in the system. Phase compensation has been performed on the monitoring torque by using the torque differentiation method. The Simulink/Carsim simulation results show that ADRC has significantly improved anti-disturbance performance compared to PID and fuzzy PID. When using ADRC, the tracking accuracy of the assisted current is enhanced by 45.8%–75.8%, and the current adjustment time is reduced by 35.6%–61.7%. After phase compensation, the monitoring torque overshoot is reduced by 83.3%. Therefore, the proposed control strategy improves EPS’s robustness and steering feel.
Investigation of crack propagation in filament wound composite samples of Mode-I by using acoustic emission technique
Authors: Farajpour Mehdi , Najafabadi Mehdi Ahmadi
Published: August 2023

A common industrial method of fabricating composite structural is filament winding, which is widely used to manufacture axisymmetric components. One of the most prevalent damage mechanisms in these composite structures is delamination, which occurs in various types of loading. In this research, the mechanical behavior and propagation of the initial crack of Mode-I in carbon/epoxy filament wound (FW) composite curve beams have been investigated via the acoustic emission (AE) method. For this purpose, at first, a composite tube was made with considering the artificial interlayer separation, and the beam specimens were cut from the longitudinal direction. At first, the initiation of the failures was determined using the AE method. Then, the growth and spread of interlayer delamination were investigated by the energy of AE signals and the sentry function. By determining the speed of the AE waves and providing a method to filter unwanted signals, the momentary position of the interlayer delamination tip during growth is predicted. The results showed that the fiber bridging phenomenon was due to the penetration of the two regions adjacent of the separation interface, and the fiber bridging length considerably affected the Mode-I delamination fracture toughness. In addition, the fracture toughness increased as the fiber bridging zone enlarged. Finally, good agreement was observed between the fracture toughness values obtained from the AE method and those found in the standard ASTM D5528.

Published: August 2023

Drawing on the theory of sociology of trust and risk, this study proposes and empirically tests a conceptual model of tourists’ new destination visit intentions. The model links tourists’ subjective knowledge to trust and risk perceptions and explores the moderating effects of social media influencers (human vs. virtual) and tourists’ psychographic factors in this context. Data were collected from two studies: Study 1, through a survey distributed to participants in Malaysia ( n = 493 valid responses); and Study 2, through a between-subjects design experiment with another sample of participants in Malaysia ( n = 470 valid responses). The findings expand knowledge in tourism research by showing that destination trust mediates how subjective knowledge influences perceived risk. Optimism and life satisfaction have significant moderating effects in this context. Furthermore, the relationship between destination trust and visit intention is moderated by human and virtual influencers, according to whether their message is positive or negative.
Performance analysis of distributed power systems using error dynamics passive output feedback control
Authors: S Monesha , S Selvaperumal
Published: August 2023

This paper presents a novel control approach for integrated converters using Exact Tracking Error Dynamics Passive Output Feedback control and Exact Static Error Dynamics Passive Output Feedback control. By continuously injecting active distributed power systems (DPS) power sources into the utility grid and loads, the approach reduces harmonic current distortion and maintains unity for the grid’s power factor. The paper compares existing control methods, such as P, PI, proportional–integral–derivative (PID), energy structuring and damping infusion and interconnection and damping assignment—passivity-based control and considers the impacts of instantaneous fluctuations in reference current elements on the AC side and oscillations in DC voltage generated by the DC-link voltage. Relevant switching state functions are designed, and if the maximum power can be fed exceeds the required power from grid-connected loads, the true, reactive, and harmonic current elements of loads are adjusted dynamically, resulting in in-phase sinewave grid currents. The performance analysis is performed using MATLAB/Simulink, and a smaller research prototype is built and discussed.
A Rare Report of Proliferative Fasciitis of the Ear in a Pediatric Patient
Authors: Lipman Ruthann I. , Gober Madeline Krentz , Mascia Brett , Anon Jack B.
Published: August 2023

Nodular fasciitis is a relatively uncommon disorder that occurs in soft tissues and results in a rapidly growing mass predominately found in adults. Proliferative fasciitis is a rarer variant of nodular fasciitis that is typically found in adults over age 40 and is extremely rare in pediatric patients. This case report involves a pediatric patient who presented with a large, posterior, rapidly growing mass on the right ear. This was excised and the subsequent biopsy required several pathology consultations and opinions. Multiple immunohistochemical and molecular studies eventually led to the findings of spindle cell mesenchymal neoplasm, consistent with proliferative fasciitis of pediatric type.
Removal of Calcium Hydroxide Paste Leaked Into the Maxillary Sinus
Authors: Kim Dohee , Kim Young , Han Jeong Joon
Published: August 2023

Calcium hydroxide is a widely used endodontic medicament with antibacterial activity. When excessive pressure is applied during injection of calcium hydroxide paste or apical perforation occurs, calcium hydroxide can leak into the maxillary sinus and is adsorbed onto the sinus membrane. Although a leakage of calcium hydroxide may not usually cause clinical symptoms, when a large amount of leakage occurs, it can cause degeneration of adjacent tissue and functional disorder, requiring immediate surgical removal. However, due to adsorption to the sinus membrane, calcium hydroxide leaked into the maxillary sinus is difficult to remove completely. Here, we describe the case of a 47-year-old patient in whom a large amount of calcium hydroxide leaked into the maxillary sinus and was successfully removed using modified endoscopic-assisted sinus surgery, and favorable bone regeneration and sinus membrane regeneration were achieved. In addition, histological and ultrastructural changes of the membrane resulted from the calcium hydroxide were presented.
IgG4-Related Disease Involving the Paranasal Sinus Orbit: A Case Report
Authors: Cao Changxing , Liang Qiulin , Feng Chao , Guo Shasha
Published: August 2023

Immunoglobulin G4-related disease (IgG4-RD) is a rare and complicated clinical disease entity newly identified in recent years. It is a chronic inflammatory disease mediated by the immune system that can affect various organs throughout the body, such as the pancreas, salivary gland (submandibular gland, parotid gland, and sublingual gland), lacrimal gland, and thyroid gland. In rare cases, it involves sinuses and orbits. We describe a 44-year-old patient who was hospitalized with distension and pain in her right eye. The lesions included the nasal sinus and orbit. IgG4-RD was diagnosed after surgery and the patient was treated without complications. This case report helps to provide clinicians with additional information to assist in the diagnosis of the disease.
Reinke’s Edema: Cold Steel Versus Radiofrequency Coblation
Authors: Lou Xudan , Lou Zhengcai
Published: August 2023

Objective:

This study compared the effects of radiofrequency (RF) coblation and cold steel (CS) surgery for the treatment of Reinke’s edema (RE).

Methods:

A retrospective analysis was conducted on 61 patients with RE, with 33 (54.1%) in the CS surgery group and 28 (45.9%) in the RF coblation group. The primary endpoints were the bilateral operation time and dyspnea severity, assessed preoperatively and at 1 and 3 months postoperatively. Secondary endpoints included subjective and objective vocal assessments, laryngovideostroboscopy (LVS) images, and Voice Handicap Index-10 (VHI-10) scores obtained before and at 1 and 3 months postoperatively.

Results:

The average bilateral operation time was significantly shorter in the RF coblation group (24.2 ± 3.9 min) compared to the CS group (38.4 ± 5.2 min) ( P = .041). All patients experienced a decrease in their Dyspnea Severity Index (DSI) scores postoperatively, with no significant differences observed between the two groups at any time point. However, improvements in the grade of hoarseness, roughness, and asthenia were significantly greater in the RF coblation group than in the CS group ( P < .001). There were no statistically significant differences in breathiness and strain between the two groups. The average VHI-10 score significantly decreased from preoperative values in both groups ( P < .001), with no significant differences observed between the two groups at any time point.

Conclusions:

The RF coblation procedure is a reliable and safe method for RE surgery, offering an effective treatment choice for RE.
Spontaneous Intracranial Hypotension: An Uncommon Cause of Postural Vestibulocochlear Symptoms
Authors: Sharp Samuel , Silbert Peter L. , Davies Scott , Friedland Peter
Published: August 2023

Spontaneous intracranial hypotension is an uncommon but increasingly recognized condition characterized by an orthostatic headache secondary to low cerebrospinal fluid pressure. Vestibulocochlear symptoms are common but rarely the only presenting feature and can be challenging to differentiate from Meniere’s disease. We present a case series that highlights the common vestibulocochlear symptoms and a review of the literature to increase awareness amongst otolaryngologists and highlight the path to diagnosis and management of this condition
Racial Capitalism and Social Psychology: A Note for Future Research
Authors: Robinson John N. , Korver-Glenn Elizabeth , Besbris Max
Published: August 2023

In this research note, we describe how theories of racial capitalism offer important insights into social psychological processes of racial discrimination, stereotyping, and more. First, the racial capitalism framework sheds light on the material conditions that shape social psychological aspects of racial domination and oppression, including processes of identity formation. Second, racial capitalism thinkers have emphasized how capitalism instrumentalizes racial identity and differentiation to spur accumulation. Third, racial capitalism points to intersectionality as key to understanding how social-structural factors shape the social psychological experiences and effects of discrimination for the racially disadvantaged. Social psychologists should incorporate these insights into their examinations of race and racism.
Shifting or Settled? Tracking Racial Animus During COVID-19
Authors: Stewart Evan , Beckman Diane
Published: August 2023

Is racial animus sensitive to social shocks, or is it a disposition that resists change? The early COVID-19 pandemic was accompanied by incidents of prejudice and discrimination against the Asian American community in the United States. We investigate whether comparable shifts in public opinion also occurred during this time using survey data fielded through 2019 and 2020. We compare changes in anti-Asian sentiment to changes in anti-Black, anti-Latino, and anti-white sentiment, finding a distinct rise in anti-Asian sentiment starting in January 2020 that slowly returns to 2019 levels. We also compare neutral response options to both positive and negative responses and find polarization in sentiment where partisanship, political interest, and self-reported COVID-19 exposure all associate with a higher likelihood of expressing both positive and negative sentiment relative to neutral responses about Asian Americans. We discuss these findings in line with a theory of racial animus as a disposition that is subject to temporary, episodic activation.
Playing with Oppression: Latinx Students’ Use of Humor to Navigate Assumed Racism
Authors: Zhang Jienian
Published: August 2023

This article demonstrates how a group of Latinx students in a suburban high school use humor as an interactional strategy to negotiate and sometimes resist perceived racial meanings. Using ethnography, I find two distinct types of ambiguity central in such humor: (1) ambiguity in humor and (2) ambiguity in situational cues that prompt humor. The students interpret these often-ambiguous situational cues as relevant to racism and then use humor to play with assumed racism. Furthermore, they use humor in several distinct but not mutually exclusive forms: (1) preemptive testing, (2) constructing insider/outsider status, and (3) self-(re)defining. By integrating role theories in the analysis, I show the theoretical importance of analyzing both the social cues that prompt the humor and the humor itself. I suggest that such humorous interactions ultimately illuminate racial inequalities that usually remain undetected in interactions or in broader social contexts.
Seeing Behavior as Black, Brown, or White: Teachers’ Racial/Ethnic Bias in Perceptions of Routine Classroom Misbehavior
Authors: Owens Jayanti
Published: August 2023

Building on social psychological research on individual bias, this article uses the concept of “perceived blameworthiness” to investigate whether Black and Latino boys are perceived by teachers as being more culpable, or “blameworthy,” than White boys for objectively identical, routine classroom misbehavior at school. To isolate teacher bias from true differences in behavior, I use an original video experiment involving 1,339 teachers in 295 U.S. schools. Teachers in the experiment are randomly assigned to view and respond to a video of a White, Black, or Latino boy committing identical misbehavior. I find that Black boys experience teacher blaming bias, where they are perceived as being more “blameworthy” than White boys for identical misbehavior. Results for Latino boys are directionally similar to those for Black boys but do not reach statistical significance. Findings have implications for racialized assessments of behavior across a range of evaluative contexts.
Racism Over Time: Experiences from a Panel Study of Black Americans
Authors: Alinor Malissa , Simons Ronald L. , Lei Man-Kit
Published: August 2023

Existing research demonstrates that racial discrimination negatively affects life outcomes for Black Americans. Yet, it is unknown how exposure to racial discrimination changes over time. To address this gap, we (1) assess the pattern of experiences with racial discrimination from age 10 to 30; (2) test how exposure to discrimination changes within childhood, adolescence, and adulthood; and (3) analyze factors associated with experiencing racial discrimination over time. To accomplish this, we use seven waves of the Family and Community Health Study, a longitudinal data set of Black Americans. We observe a curvilinear relationship between discrimination and age such that exposure initially increases in childhood, peaks in adolescence, then declines in adulthood. Using piecewise growth modeling, we find support for this pattern, marking the period from childhood to adolescence as a critical time period. Finally, factors such as geographical location, criminal justice involvement, and attending college are associated with experiencing greater racial discrimination.
